 For purposes of this definition, whenever pro forma effect is to be given to an Asset Disposition or an acquisition of assets,
the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in accordance with Regulation S-X
under the Securities Act. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable
rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months). If any Indebtedness that is being given pro forma effect was

Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, the Intercreditor Agreements, the Applicable Procedures or stock exchange rules or usage. Each Note will be dated the date of its authentication.

 The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and
the Issuer, the Subsidiary Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the
express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of
outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal
amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

and no series of Notes shall have the right to vote or consent as a separate class on any matter. 
 The Trustee may appoint an
authenticating agent (the “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate Notes. Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An Authenticating Agent has the same rights as an Agent to deal with the Issuer and Affiliates of the Issuer.

 The Issuer shall maintain an office or agency which shall initially be the office of the Corporate Trust Office of
the Trustee, where (a) Notes may be presented or surrendered for registration of transfer or for exchange (the “Registrar”) and (b) Notes may be presented or surrendered for payment (the “Paying Agent”).
The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Register”). The Issuer, upon prior written notice to the Trustee, may have one or more co-Registrars and one or more additional Paying Agents
reasonably acceptable to the Trustee. The term “Paying Agent” includes any additional Paying Agent. 
 The
Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee in writing, in
advance, of the name and address of any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such. 

The Issuer initially appoints the Trustee as Registrar and Paying Agent in connection with the Notes. The Paying Agent or Registrar may
resign upon thirty (30) days’ written notice to the Issuer. 
 Section 2.04  Obligations of
Paying Agent. 
 The Issuer shall require each Paying Agent other than the Trustee to agree in writing that such Paying
Agent shall hold separate and apart from, and not commingle with any other properties, for the benefit of the Holders or the Trustee, all assets held by the Paying Agent for the payment of principal of, or interest on, the Notes (whether such assets
have been distributed to it by the Issuer or any other obligor on the Notes), and the Issuer and the Paying Agent shall notify the Trustee in writing of any Default by the Issuer (or any other obligor on the Notes) in making any such payment. The
Issuer at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any Payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon receipt by the Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying
Agent shall have no further liability for such assets.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and
addresses of the Holders. If the Trustee is not the Registrar, the Issuer shall furnish or cause the Registrar to furnish to the Trustee at least seven (7) Business Days before each Interest Payment Date and at such other times as the Trustee
may 

  
 43 

 
request in writing a list as of such date and in such form as the Trustee may reasonably request of the names and addresses of the Holders, which list may be conclusively relied upon by the
Trustee. 
 Section 2.06  Transfer and Exchange. 

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee
of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be
exchanged by the Issuer for certificated Notes in fully registered form without interest coupons (“Definitive Notes”) if: 
 (1) the Depositary notifies the Issuer that it is unwilling or unable to continue as depository for the Global Notes and a successor Depositary is not appointed by the Issuer within ninety (90) days
of such notice; 
 (2) the Issuer in its sole discretion determines that the Global Notes (in whole but not in
part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; provided that in no event shall the Notes issued under Regulation S be exchanged by the Issuer for Definitive Notes prior to
(A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or 

(3) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary to
issue Definitive Notes. 
 Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive
Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered
in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A
Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or
(c) hereof. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and
exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. None of the Issuer, the Trustee, Paying Agent, nor any agent of the
Issuer shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Note, or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in
the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a
U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or

 If any such transfer is effected pursuant to subparagraph (4) above at a time when an
Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Officers’ Certificate in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in

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

(1) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee will authenticate Global
Notes and Definitive Notes upon receipt of an Officers’ Certificate in accordance with Section 2.02 hereof. 

  
 55 

 (2) No service charge will be made to a Holder of a beneficial interest in a
Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than
any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 4.10, 4.11 and 9.04 hereof). 

(3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in
whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (4) All Global Notes and
Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes, made in accordance with this Section 2.06, will be the valid obligations of the Issuer, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (5) Neither the Registrar nor the Issuer shall be required: 
 (i)
to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business fifteen (15) days before the day of any mailing of a notice of redemption of Notes under Section 3.03 hereof and
ending at the close of business on the mailing of such notice of redemption; 
 (ii) to register the transfer of
or to exchange any Note called for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 
 (iii) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date. 

(6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may
deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the
Issuer shall be affected by notice to the contrary. 
 (7) The Trustee will authenticate Global Notes and
Definitive Notes in accordance with the provisions of Section 2.02 hereof. 
 (8) All certifications,
certificates and Opinions of Counsel required to be submitted pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

 (10) Each Holder agrees to indemnify the Issuer and the Trustee against any liability that may result from the
transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable United States Federal or state securities law. 

  
 56 

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

Section 2.07  Replacement Notes. 
 If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims in writing that the Note has been lost, destroyed or wrongfully taken, then, in the absence of written notice to the
Issuer upon its request or the Trustee that such Note has been acquired by a protected purchaser, the Issuer shall issue and the Trustee shall authenticate a replacement Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding. Except with respect to mutilated Notes, such Holder must provide an affidavit of lost certificate and an indemnity bond or other indemnity, sufficient in the judgment of both (i) the Trustee to protect the Trustee
and (ii) the Issuer to protect the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Issuer may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note, including
reasonable fees and expenses of its counsel and of the Trustee and its counsel. In case any mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Issuer in its discretion may pay such Note instead
of issuing a new Note in replacement thereof. Every replacement Note shall constitute an additional obligation of the Issuer, entitled to the benefits of this Indenture. 
 Section 2.08  Outstanding Notes. 
 Notes outstanding
at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Subject to the provisions of
Section 2.09 and Section 2.11 hereof, a Note does not cease to be outstanding because the Issuer or any of its Affiliates holds the Note. 
 If a Note is replaced pursuant to Section 2.07 hereof (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee receives proof satisfactory to
it that the replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07 hereof. 

If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay
all of the principal and interest, due on the Notes payable on that date and is not prohibited from paying such U.S. Legal Tender or U.S. Government Obligations to the Holders thereof pursuant to the terms of this Indenture, then on and after that
date such Notes cease to be outstanding and interest on them ceases to accrue. 

  
 57 

 Section 2.09  Treasury Notes; When Notes Are Disregarded.

 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent
or notice, Notes owned by the Issuer or any of its Affiliates shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes the pledgee’s right so
to act with respect to such Notes and that the pledgee is not one of the Issuer or any other obligor upon the Notes or any Affiliate of the Issuer or of such other obligor. 
 Section 2.10  Temporary Notes. 
 Until certificates
representing Notes are ready for delivery, the Issuer may prepare and execute and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Issuer in the form of an Officers’ Certificate. The Officers’
Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of certificates representing Notes but may have
variations that the Issuer consider appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate upon receipt of a written order of the Issuer pursuant to Section 2.02 hereof
certificates representing Notes in exchange for temporary Notes. Until so exchanged, the temporary Notes shall be entitled to the same benefits under this Indenture as certificates representing Notes. 

Section 2.11  Cancellation. 
 The Issuer at any time may deliver Notes previously authenticated hereunder to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them
for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel all Notes surrendered for transfer, exchange, payment or cancellation. Subject to
Section 2.07 hereof, the Issuer may not issue new Notes to replace Notes that they have paid or delivered to the Trustee for cancellation. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption
or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11 hereof. The Trustee shall dispose of all cancelled Notes in accordance
with customary procedures or, at the written request of the Issuer, shall return the same to the Issuer (unless applicable law or the Trustee’s procedures requires the Trustee to retain possession of such cancelled Notes). 

Section 2.12  CUSIP Numbers. 
 A “CUSIP” number shall be printed on the Notes, and the Trustee shall use the CUSIP number in notices of redemption, purchase or exchange as a convenience to Holders; provided that
any such notice may state that no representation is made as to the correctness or accuracy of 

  
 58 

 
the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee
in writing of any change in the CUSIP number. 
 Section 2.13  Deposit of Moneys. 

Prior to 11:00 a.m. New York City time on each Interest Payment Date and the Maturity Date, the Issuer shall deposit with the Paying
Agent U.S. Legal Tender sufficient to make cash payments, if any, due on such Interest Payment Date or the Maturity Date, as the case may be.

that after giving effect thereto, (a) the Issuer would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Coverage Ratio test in Section 4.08(a) hereof, or (b) the Consolidated
Coverage Ratio would be no worse than immediately prior thereto;

criteria of more than one of the categories of Indebtedness described in Section 4.08(b)(1) through (14) hereof or is entitled to be Incurred pursuant to Section 4.08(a) hereof, the Issuer shall, in its sole
discretion, classify (or later reclassify) such item of Indebtedness in any manner that complies with this Section 4.08 (including splitting into multiple exceptions) and shall only be required to include the amount and type of such
Indebtedness in one of such clauses of Section 4.08(b) or pursuant to Section 4.08(a) hereof; provided that all Indebtedness under the ABL Credit Agreement outstanding on the Issue Date shall be deemed to have been
Incurred on the Issue Date pursuant to Section 4.08(b)(1) hereof and the Issuer shall not be permitted to later reclassify all or any portion of such Indebtedness under the ABL Credit Agreement outstanding on the Issue Date. 

(d) The Issuer shall not, and shall not permit any Subsidiary Guarantor to, directly or indirectly Incur any Indebtedness that is
contractually subordinated in right of payment to any Indebtedness of the Issuer or such Subsidiary Guarantor, as the case may be, unless such Indebtedness is also contractually subordinated in right of payment to the Notes or the applicable
Subsidiary Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Subsidiary Guarantor, as the case may be; provided that (i) unsecured Indebtedness shall not be
treated as contractually subordinated to any other Indebtedness merely because it is unsecured; and (ii) Indebtedness shall not be treated as contractually subordinated in right of payment to other Indebtedness merely because such Indebtedness
has a junior priority with respect to any collateral. 

  
 67 

 (e) For purposes of determining compliance with any U.S. dollar-denominated restriction on
the Incurrence of Indebtedness, where the Indebtedness Incurred is denominated in a different currency, the amount of such Indebtedness will be the U.S. dollar equivalent determined on the date of the Incurrence of such Indebtedness; provided,
however, that if any such Indebtedness denominated in a different currency is subject to a currency agreement with respect to U.S. dollars covering all principal, premium, if any, and interest payable on such Indebtedness, the amount of such
Indebtedness expressed in U.S. dollars will be as provided in such currency agreement. The principal amount of any Refinancing Indebtedness Incurred in the same currency as the Indebtedness being refinanced will be the U.S. dollar equivalent of the
Indebtedness being refinanced, except to the extent that (1) such U.S. dollar equivalent was determined based on a currency agreement, in which case the Refinancing Indebtedness will be determined in accordance with the preceding sentence, and
(2) the principal amount of the Refinancing Indebtedness exceeds the principal amount of the Indebtedness being refinanced, in which case the U.S. dollar equivalent of such excess will be determined on the date such Refinancing Indebtedness is
Incurred. The maximum amount of Indebtedness that the Issuer or any Restricted Subsidiary may Incur pursuant to this covenant shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in
exchange rates or currency values. 
 Section 4.09   Limitation on Restricted Payments.

time the Issuer or such Restricted Subsidiary makes such Restricted Payment:

Indebtedness pursuant to Section 4.08(a) hereof; or

(proportionate to the Issuer’s equity interest in such Subsidiary) of the fair market value of the net assets of an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary after the Issue Date;
provided, however, that the foregoing sum shall not exceed, in the case of any such Person or Unrestricted Subsidiary, the amount of Investments previously made (and treated as a Restricted Payment) by the Issuer or any Restricted
Subsidiary in such Person or Unrestricted Subsidiary.

provided, however, that such dividend or redemption payment shall be included in the calculation of the amount of Restricted Payments;

provided, however, that (A) such Restricted Payments shall be excluded in the calculation of the amount of Restricted Payments, (B) will not be considered to be Net Cash Proceeds of a Stock Offering for purposes of

Restricted Payment as provided in this Section 4.09(b)(2)) and (D) will not be considered to be Net Cash Proceeds for purposes of Section 4.08(b)(14) hereof;

retirement for value of Subordinated Obligations of the Issuer or any Subsidiary Guarantor made by exchange for, or out of the proceeds of the substantially concurrent sale of, Subordinated Obligations that constitute Refinancing Indebtedness of the
Issuer; provided, however, that such purchase, repurchase, redemption, defeasance or other acquisition or retirement for value shall be excluded in the calculation of the amount of Restricted Payments; 

(4) the repurchase, redemption, cancellation or other acquisition or retirement of any Capital Stock of the Issuer or any
of its Subsidiaries from any future, current or former officer, director, employee or consultants of the Issuer or any of its Subsidiaries (or their permitted transferees, assigns, estates or heirs), pursuant to any management equity plan, stock

Disqualified Stock) of the Issuer to members of management, directors or consultants of the Issuer or any of its Subsidiaries that occurs after the Issue Date to the extent the Net Cash Proceeds from the sale of Capital Stock have not otherwise been
applied to the making of Restricted Payments pursuant to Sections 4.09(a)(3)(ii) or 4.09(b)(2) hereof; plus (ii) the cash proceeds of “key man” life insurance policies received by the Issuer or its Restricted

(6) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar
distribution) by a Restricted Subsidiary of the Issuer to the Holders of its Capital Stock on a pro rata basis; provided, however, that such payment shall be excluded in the calculation of the amount of Restricted Payments; 

  
 70 

 (7) the repurchase of Capital Stock deemed to occur upon the exercise of
stock options or warrants or similar stock-based instruments to the extent such Capital Stock represents a portion of the exercise price of those stock options or warrants or similar stock-based instruments or in connection with a gross-up or tax

(8) payments of cash, dividends, distributions, advances or other Restricted Payments by the Issuer or any of its
Restricted Subsidiaries to allow the payment of cash in lieu of the issuance of fractional shares upon (i) the exercise of options or warrants or (ii) the conversion or exchange of Capital Stock of any such Person; provided,

however, that such payment shall be included in the calculation of the amount of Restricted Payments; or 

(12) other Restricted Payments in an aggregate amount not to exceed $10.0 million; provided, however, that

Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Issuer or such Restricted Subsidiary, as the case may be, pursuant to
the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant will be determined in good faith by the Board of Directors of the Issuer. The Board of Directors’ determination must be

 Section 4.10  Repurchase upon Change of Control. 

(a) Upon the occurrence of a Change of Control, unless the Issuer at such time has given notice of redemption pursuant to
Section 3.01 hereof with respect to all outstanding Notes, the Issuer shall make an offer to purchase all of the Notes as described below (the “Change of Control Offer”), at a purchase price in cash (“Change of
Control Payment”) equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to but excluding, the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive
interest due on the relevant Interest Payment Date). 
 (b) Within thirty (30) days following a Change of Control, unless
the Issuer at such time has given notice of redemption pursuant to Section 3.01 hereof with respect to all outstanding Notes, the Issuer shall mail by electronic transmission (for Notes held in book-entry form) or first class mail a
notice to each Holder with a copy to the Trustee. Such notice shall state: 
 (1) that a Change of Control has
occurred and that such Holder has the right to require the Issuer to purchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but excluding, the date of
purchase (subject to the right of Holders of record on the relevant Record Date to receive interest on the relevant Interest Payment Date); 
 (2) the circumstances and relevant facts regarding such Change of Control; 
 (3) the purchase date (which shall be no earlier than thirty (30) days nor later than sixty (60) days from the date such notice is mailed, other than as may be required by law) (the

Paying Agent shall promptly deliver to the Holders so tendered the purchase price for such Notes and the Issuer shall promptly issue and the Trustee shall promptly (but in any case not later than five (5) days after the Change of Control
Payment Date) authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered; provided that each such new Note shall be in a principal
amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Notes not so accepted shall be promptly mailed (or caused to be transferred by book-entry) by the Issuer to the Holders thereof. For purposes of this Section 4.10,
the Trustee shall act as the Paying Agent. 

  
 72 

 (e) Any amounts remaining after the purchase of Notes pursuant to a Change of Control Offer
shall promptly be returned by the Trustee to the Issuer. 
 (f) Neither the Board of Directors of the Issuer nor the Trustee may
waive the Issuer’s obligation to offer to purchase the Notes pursuant to this Section 4.10. 
 (g) The Issuer
shall comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change
of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.10, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section 4.10 by virtue thereof. 
 (h) The Issuer shall not be required to make a
Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control
Offer made by the Issuer and purchases all Notes validly tendered and not properly withdrawn under such Change of Control Offer or (2) a notice of redemption has been given to the Trustee with respect to all of the Notes pursuant to
Section 3.03 hereof unless and until there is a default in payment of the applicable Redemption Price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, or
conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 
 Section 4.11  Limitation on Sales of Assets and Subsidiary Stock. 
 (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless: 

(1) the Issuer or such Restricted Subsidiary receives consideration at least equal to the fair market value (such fair
market value to be determined on the date of contractually agreeing to such Asset Disposition in good faith by an Officer of the Issuer or of such Restricted Subsidiary with responsibility for such transaction, or the Board of Directors if the Asset
Disposition exceeds $20.0 million, which determination shall be conclusive evidence of compliance with this provision), of the equity and assets subject to such Asset Disposition; 

(2) at least 75% of the consideration received by the Issuer or such Restricted Subsidiary is in the form of cash or
Temporary Cash Investments, Additional Assets or any combination thereof (collectively, the “Cash Consideration”); and 
 (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Issuer (or such Restricted Subsidiary, as the case may be), at its option: 

  
 73 

 (i) to the extent the property that is subject to such Asset Disposition
constitutes ABL Facility Priority Shared Collateral, to repay or prepay Indebtedness under the ABL Credit Agreement within 365 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, provided such
prepayment or repayment permanently retires, or reduces the related loan commitment for, such Indebtedness in an amount equal to the principal amount so prepaid or repaid; 

(ii) to the extent the property that is subject to such Asset Disposition constitutes INMETCO Collateral, to repay or
prepay Indebtedness under the INMETCO Facility within 365 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, provided such prepayment or repayment permanently retires, or reduces the related
loan commitment for, such Indebtedness in an amount equal to the principal amount so prepaid or repaid; 
 (iii)
to the extent the Issuer elects, to acquire Additional Assets in a Permitted Business within 365 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; 

(iv) to make a capital expenditure; 

(v) to the extent the property that is subject to such Asset Disposition does not constitute Collateral, to repay
Indebtedness and other Obligations of a Restricted Subsidiary of the Issuer that is not a Subsidiary Guarantor (other than Indebtedness owed to the Issuer or a Restricted Subsidiary of the Issuer); 

(vi) to the extent the property that is subject to such Asset Disposition does not constitute Collateral, to repay
(i) Indebtedness or other Obligations of the Issuer that rank pari passu with the Notes or (ii) Indebtedness and other Obligations of a Subsidiary Guarantor that rank pari passu with such Subsidiary Guarantor’s
Subsidiary Guarantee (other than Indebtedness owed to the Issuer or a Restricted Subsidiary of the Issuer); provided that the Issuer shall equally and ratably redeem or repurchase the Notes pursuant to Section 3.01 hereof or by
making an offer (in accordance with the procedures set forth in Section 4.11(b) hereof for an Asset Disposition Offer) to all holders to purchase the Notes at 100% of the principal amount thereof, plus accrued and unpaid interest, if
any, to but not including the date of repayment; or 
 (vii) to make a combination of repayments and investments
permitted by the foregoing clauses (i) through (vi). 
 Pending application of Net Available Cash pursuant to this
Section 4.11(a)(3), such Net Available Cash may be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit Indebtedness. 
 For the purposes of Section 4.11(a), the following shall be deemed to be cash or Temporary Cash Investments: (i) any liabilities, as shown on the Issuer’s or such Restricted
Subsidiary’s most recent balance sheet or in the notes thereto, of the Issuer or any Restricted 

  
 74 

 
Subsidiary (other than contingent liabilities and Subordinated Obligations) that are assumed by the transferee of any such assets and from which the Issuer and all Restricted Subsidiaries of the
Issuer have been released; (ii) any securities, notes or other obligations received by the Issuer or any such Restricted Subsidiary from such transferee that are within 180 days after the closing of such Asset Disposition, subject to ordinary
settlement periods, converted by the Issuer or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion; or (iii) any Designated Non-cash Consideration received by the Issuer or any of its Restricted
Subsidiaries in such Asset Disposition having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iii) that is at that time outstanding not to exceed $15.0 million
with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value. 
 (b) The amount of Net Available Cash not applied or invested as provided above will constitute “Excess Proceeds.” Within thirty (30) days of the date on which the aggregate amount of
Excess Proceeds equals or exceeds $20.0 million, or on any earlier date, if the Issuer so elects, the Issuer shall make such offer to purchase Notes (an “Asset Disposition Offer”) and any other Pari Passu Lien Indebtedness of the
Issuer containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, on or before the 366th day after the later of the date of such Asset Disposition or
the receipt of such Net Available Cash, provided, however, that if during such 365-day period referenced in clause (3)(iii) of Section 4.11(a) hereof, the Issuer or a Restricted Subsidiary enters into a definitive
binding agreement committing it to apply such Net Available Cash in accordance with the requirements of clause (3)(iii) of Section 4.11(a) hereof within 180 days of such commitment (an “Acceptable Commitment”),
such 365-day period will be extended with respect to the amount of Net Available Cash so committed for a period not to exceed 180 days until such Net Available Cash are required to be applied in accordance with such agreement (or, if earlier, until
termination of such agreement), and shall purchase Notes tendered pursuant to an Asset Disposition Offer by the Issuer for the Notes (and such other Pari Passu Lien Indebtedness of the Issuer) at a purchase price of 100% of their principal amount
without premium, plus accrued but unpaid interest (or, in respect of such other Pari Passu Lien Indebtedness of the Issuer, such lesser price, if any, as may be provided for by the terms of such Pari Passu Lien Indebtedness of the Issuer) in
accordance with the procedures (including prorating in the event of oversubscription) set forth in this Indenture. If the aggregate purchase price of the securities tendered exceeds the amount of Excess Proceeds, the Issuer shall select the
securities to be purchased on a pro rata basis but in round denominations, which in the case of the Notes will be denominations of $2,000 principal amount or integral multiples of $1,000 in excess thereof. Upon completion of such an Asset
Disposition Offer to purchase, Excess Proceeds will be deemed to be reset to zero. If any Excess Proceeds remain after consummation of an Asset Disposition Offer, the Issuer and its Restricted Subsidiaries may use those Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. 
 (c) The Issuer shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.11. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.11, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this covenant by virtue of its
compliance with such securities laws or regulations. 

  
 75 

 Section 4.12  Limitation on Restrictions on Distributions from
Restricted Subsidiaries. 
 (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, create or permit to
exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary (A) to pay dividends or make any other distributions on its Capital Stock to the Issuer or any of its Restricted Subsidiaries or pay
any Indebtedness owed to the Issuer or a Restricted Subsidiary, (B) to make any loans or advances to the Issuer or a Restricted Subsidiary or (C) to transfer any of its property or assets to the Issuer or a Restricted Subsidiary, except:

 (1) any encumbrance or restriction in an agreement in effect on the Issue Date (including, without limitation,
pursuant to or required by the ABL Credit Agreement or related documents as in effect on the Issue Date); 
 (2)
any encumbrance or restriction with respect to or pursuant to an instrument relating to any Indebtedness or Capital Stock of a Person in effect on or prior to the date on which such Person was acquired by the Issuer or became a Restricted Subsidiary
of the Issuer (other than Indebtedness Incurred as consideration in, or to provide all or any portion of the funds or credit support utilized to consummate, the transaction or series of related transactions pursuant to which such Person became a
Restricted Subsidiary or was acquired by the Issuer); 
 (3) any such encumbrance or restriction consisting of
customary nonassignment provisions in leases, subleases or licenses to the extent such provisions restrict the transfer of the lease or the property or assets subject to such agreements; 

(4) in the case of clause (C) above, any encumbrances or restrictions related to purchase money obligations or other
Obligations described in Section 4.08(b)(6) hereof for property so acquired that in each case impose restrictions of the nature described in clause (C) above on the property so acquired; 

(5) any restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or
disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary pending the closing of such sale or disposition; 
 (6) any encumbrance or restriction existing under or by reason of applicable law, rule, regulation or order; 
 (7) any encumbrance or restriction existing under or by reason of any other agreements governing Indebtedness permitted to be Incurred pursuant to Section 4.08 hereof that contains
encumbrances and restrictions that are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date under the ABL Credit Agreement (as determined in good faith by the Board of Directors of the
Issuer); 

  
 76 

 (8) Liens permitted to be Incurred under Section 4.13 hereof

 Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer shall furnish to the Holders of Notes, within fifteen (15) days after the time periods specified in the SEC’s
rules and regulations for a company that is subject to Section 13(a) or 15(d) of the Exchange Act: 
 (1)
all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Issuer were required to file such Forms, including a “Management’s Discussion and Analysis of
Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Issuer’s certified independent accountants; and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file
such reports; 
 provided that any such above information or reports filed with the Electronic Data Gathering and Retrieval System of the
SEC (or successor system) and available publicly on the Internet shall be deemed to be furnished to the Holders of Notes. 
 The
quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of
operations of the Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of the Issuer’s Unrestricted Subsidiaries. 
 In addition, whether or not required by the SEC, the Issuer shall file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability
within fifteen (15) days after the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request.
The Issuer agrees that it shall not take any action for the purpose of causing the SEC not to accept such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Issuer shall post the reports specified in
the preceding sentence on its website within the time periods that would apply if the Issuer were required to file those reports with the SEC. 

  
 82 

 In addition, to the extent not satisfied by the foregoing, the Issuer shall agree that, for
so long as any Notes remain outstanding, it shall furnish to Holders of Notes and securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

 Section 4.21  Changes in Covenants When Notes Rated Investment Grade. 

(a) If on any date following the Issue Date: 
 (1) the Notes are rated Investment Grade by both of the Rating Agencies; and 
 (2) no Default or Event of Default shall have occurred and be continuing (a “Suspension Event”), 
 then, beginning on that day and subject to the provisions of the following paragraph, the covenants under Sections 4.08, 4.09, 4.11, 4.12, 4.14, 4.16 and
5.01(a)(3) hereof will be suspended (collectively, the “Suspended Covenants”). 
 (b) During any period
that the foregoing covenants have been suspended, the Issuer’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the second paragraph of the definition of “Unrestricted Subsidiary”
unless the Issuer’s Board of Directors would have been able, under the terms of this Indenture, to designate such Subsidiaries as Unrestricted Subsidiaries if the Suspended Covenants were not suspended. Notwithstanding that the Suspended
Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the Suspension Period. In the event that the Notes are no longer rated Investment
Grade by one or both of the Rating Agencies, the foregoing covenants will be reinstituted as of and from the date on which the Notes are no longer rated Investment Grade (any such date, a “Reversion Date”). The period of time
between the suspension of covenants as set forth above and the Reversion Date is referred to as the “Suspension Period”. All Indebtedness Incurred during the Suspension Period will be deemed to have been Incurred or issued in reliance on
the exception provided by Section 4.08(b)(4). Calculations under reinstated Section 4.09 will be made as if Section 4.09 had been in effect prior to, but not during, the period that Section 4.09 was
suspended as set forth above; provided, for the sake of clarity, that no default will be deemed to have occurred solely by reason of a Restricted Payment made while Section 4.09 was suspended. For purposes of determining
compliance with Section 4.11, the Excess Proceeds from all Asset Dispositions not applied in accordance with Section 4.11 will be deemed to be reset to zero after the Reversion Date. 

(c) The Issuer and its Restricted Subsidiaries shall be permitted, without causing a Default or Event of Default, to honor any contractual
commitments to take actions following a Reversion Date; provided that such contractual commitments were entered into during the Suspension Period and not in contemplation of a reversion of the Suspended Covenants. 

Section 4.22  Further Assurances. 

  
 83 

 Neither the Issuer nor any of its Restricted Subsidiaries shall take or knowingly omit to
take any action that would materially impair the Liens in favor of the Collateral Agent, on behalf of itself, the Trustee and the Holders of the Notes, with respect to any material portion of the Collateral. The Issuer shall, and shall cause each
Subsidiary Guarantor to, at their sole cost and expense, (i) execute and deliver all such agreements and instruments as the Collateral Agent shall reasonably request to more fully or accurately describe the property intended to be Collateral or
the obligations intended to be secured by the Collateral Agreements and (ii) file any such notice filings or other agreements or instruments as may be reasonably necessary under applicable law to perfect (and maintain the perfection and
priority of) the Liens created by the Collateral Agreements, subject to Permitted Liens, at such times and at such places as the Collateral Agent may reasonably request, in each case subject to the terms of the Collateral Agreements. 

Section 4.23  Payments for Consent. 
 The Issuer shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, the Notes or any Collateral Agreement unless such consideration is offered to be paid and is paid to all holders of the Notes that consent, waive or
agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement; provided, however, that this covenant will not be breached if a Holder refuses such payment.

substantially all of the properties and assets of the Issuer.

or (3) the Issuer merging with or into an Affiliate solely for the purpose of reincorporating in another jurisdiction.

 (1) the resulting, surviving or transferee Person (if not such Subsidiary
Guarantor) shall be a Person organized and existing under the laws of the jurisdiction under which such Subsidiary Guarantor was organized or under the laws of the United States of America, or any State thereof or the District of Columbia, and, if
such Person is not the Issuer, such Person shall expressly assume, (A) by executing a Guarantee Agreement, all the obligations of such Subsidiary Guarantor, if any, under its Subsidiary Guarantee and (B) by amendment, supplement or other
instrument (in form and substance satisfactory to the Trustee and the Collateral Agent) executed and delivered to the Trustee and the Collateral Agent, all obligations of the Subsidiary Guarantor under the Collateral Agreements and in connection

 (2) immediately after giving effect to such
transaction or transactions on a pro forma basis (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such

Subsidiary Guarantee (other than by reason of release of a Subsidiary Guarantor from its Subsidiary Guarantee in accordance with the terms of this Indenture and the Guarantee). 

However, a default under clause (4) of this Section 6.01 will not constitute an Event of Default until the Trustee or
the Holders of at least 25% in principal amount of the outstanding Notes notify the Issuer of the default and the Issuer does not cure such default within the time specified after receipt of such notice. 

If a Default for a failure to report or failure to deliver a required certificate in connection with another default (the
“Initial Default”) occurs, then at the time such Initial Default is cured, such Default for a failure to report or failure to deliver a required certificate in connection with another default that resulted solely because of that
Initial Default shall also be cured without any further action. Any Default or Event of Default for the failure to comply with the time periods prescribed in Section 4.20 hereof or otherwise to deliver any notice or certificate pursuant
to any other provision of this Indenture shall be deemed to be cured upon the delivery of any such report required by such covenant or such notice or certificate, as applicable, even though such delivery is not within the prescribed period specified
in this Indenture. 
 Section 6.02   Acceleration. 

If an Event of Default (other than an Event of Default specified in Section 6.01(6) or (7) hereof) shall occur
and be continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Notes may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable by notice in writing to the
Issuer and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration.” Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in
Section 6.01(6) or (7) hereof occurs and is continuing, the principal of and interest on all the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the
Trustee or any Holders of the Notes. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any
existing Default or Event of Default and its consequences under this Indenture, if the rescission would not conflict with any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or
interest, if any, on, the Notes. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

Section 6.03   Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, or interest on the
Notes or, subject to the Intercreditor Agreements, to enforce the performance of any provision of the Notes, this Indenture or any of the other Indenture Documents. 

  
 89 

 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does
not produce any of them in the proceeding. A delay or omission by the Trustee, the Collateral Agent or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
 Section 6.04   Waiver of Past Defaults. 
 The Holders
of a majority in aggregate principal amount of the Notes then outstanding (including any Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or
purchase of, the Notes) by written notice to the Trustee may waive an existing Default or Event of Default and its consequences except (i) a continuing Default in the payment of the principal of or interest on a Note held by a non-consenting
Holder. When a Default or Event of Default is waived, such Default or Event of Default shall cease to exist and be deemed cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any
consequent right. 
 Section 6.05   Control by Majority. 

Subject to the provisions of Section 2.09 hereof and the Intercreditor Agreements, the Holders of a majority in principal
amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Collateral Agent or exercising any trust or power conferred on the Trustee or the Collateral
Agent. The Trustee or the Collateral Agent, however, may refuse to follow any direction that conflicts with law or this Indenture or any other Indenture Document or, subject to Section 7.01 hereof, that the Trustee or the Collateral
Agent determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee or the Collateral Agent in personal liability; provided, however, that the Trustee or the Collateral Agent may take
any other action deemed proper by the Trustee or the Collateral Agent that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee or the Collateral Agent shall be entitled to be furnished with indemnification
satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 

Section 6.06   Limitation on Suits. 

Subject to the provisions of Section 7.01 hereof, in case an Event of Default occurs and is continuing, the Trustee will be
under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders of the Notes unless such Holders have furnished to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless: 

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 

  
 90 

 (2) Holders of at least 25% in principal amount of the outstanding Notes
have requested the Trustee to pursue the remedy; 
 (3) such Holders have furnished the Trustee reasonable
security or indemnity against any loss, liability or expense; 
 (4) the Trustee has not complied with such
request within sixty (60) days after the receipt thereof and the offer of security or indemnity; and 
 (5)
the Holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such sixty (60) day period. 

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 any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and
interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

 Section 6.08   Collection Suit by Trustee or Collateral Agent. 

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, subject to the Intercreditor
Agreements, without the possession of any of the Notes or the production thereof in any proceeding related thereto, the Trustee or the Collateral Agent may recover judgment (i) in its own name and (ii)(x) in the case of the Trustee, as trustee
of an express trust or (y) in the case of the Collateral Agent, as collateral agent on behalf of each of the secured parties under the Security Agreement, in each case against the Issuer or any other obligor on the Notes for the whole amount of
principal of, premium, if any, and accrued interest remaining unpaid on, the Notes, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, if any, and
such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel and
any other amounts due any such Person under the Collateral Agreements and Section 7.07 hereof. 

Section 6.09   Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have
the claims of the Trustee (including any claim for the compensation, reasonable expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relating to the Issuer or any other
obligor upon the Notes, any of their respective creditors or any of their respective property and, subject to the Intercreditor Agreements, shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on
any such claims and to distribute 

  
 91 

 
the same, and any Custodian in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, reasonable expenses, taxes, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due any such
Person under the Collateral Agreements and Section 7.07 hereof. The Issuer’s payment obligations under this Section 6.09 shall be secured in accordance with the provisions of Section 7.07 hereof. Nothing
herein contained shall be deemed to authorize the Trustee or Collateral Agent to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights
of any Holder thereof, or to authorize the Trustee or the Collateral Agent, as the case may be, to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10   Priorities. 
 If the Trustee collects
any money or property pursuant to this Article VI, it shall, subject to the terms of the Intercreditor Agreements, pay out the money or property in the following order: 
 First: to the Trustee, the Collateral Agent, the Paying Agent and the Registrar for amounts due under Section 7.07 hereof and under the other Indenture Documents (including payment of all
compensation expense, all liabilities incurred and all advances made by the Trustee or the Collateral Agent, as the case may be, and the costs and expenses of collection); 
 Second: if the Holders are forced to proceed against the Issuer directly without the Trustee or the Collateral Agent, to Holders for their collection costs; 

Third: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 
 Fourth: to the Issuer or any other obligor on the Notes, as their interests may appear, or as a court of competent jurisdiction may direct. 

The Trustee, upon prior written notice to the Issuer, may fix a Record Date and payment date for any payment to Holders pursuant to this
Section 6.10. 
 Section 6.11   Undertaking for Costs. 

All parties to this Indenture agree, and each Holder by its acceptance of its Note shall be deemed to have agreed, that in any suit for
the enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the Collateral Agent, as the case may be, for any action taken or omitted by it as Trustee or the Collateral Agent, as the case may be, a court in its
discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee or the Collateral Agent, as the case may be, a suit by a Holder
pursuant to Section 6.07 hereof, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes. 

  
 92 

 Section 6.12   Restoration of Rights and Remedies. 

If the Trustee, the Collateral Agent or any Holder has instituted any proceedings to enforce any right or remedy under this Indenture and
such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee, the Collateral Agent or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, the
Trustee, the Collateral Agent and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee, the Collateral Agent and the Holders shall continue as though no
such proceeding has been instituted. 
 ARTICLE VII 

TRUSTEE AND COLLATERAL AGENT 
 Section 7.01   Duties of Trustee and the Collateral Agent. 
 The duties and responsibilities of the Trustee shall be as set forth herein. 
 (a)
If an Event of Default has occurred and is continuing, each of the Trustee and the Collateral Agent shall exercise such rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise thereof as a prudent
person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
 (b) With respect to
the Trustee, except during the continuance of an Event of Default, and at all times with respect to the Collateral Agent: 
 (1) the duties of the Trustee and the Collateral Agent shall be determined solely by the express provisions of this Indenture, the Collateral Agreements and the Intercreditor Agreements and the Trustee
and the Collateral Agent need perform only those duties that are specifically set forth in this Indenture, the Collateral Agreements and the Intercreditor Agreements and no others, and no implied covenants or obligations shall be read into this
Indenture against the Trustee and the Collateral Agent; and 
 (2) in the absence of bad faith on its part, the
Trustee and the Collateral Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and the Collateral Agent and conforming to the
requirements of this Indenture, the Collateral Agreements and the Intercreditor Agreements. However, in the case of any such certificates or opinions which by any provision hereof or the Collateral Agreements or the Intercreditor Agreements are
specifically required to be furnished to the Trustee or the Collateral Agent, as applicable, the Trustee or the Collateral Agent, as applicable, shall examine the certificates and opinions to determine whether or not they conform on their face to
the requirements of this Indenture, the Collateral Agreements and the Intercreditor Agreements, as applicable (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 

  
 93 

 (c) Neither the Trustee nor the Collateral Agent may be relieved from liabilities for its
own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this
clause (c) does not limit the effect of clause (b) of this Section 7.01; 
 (2) neither the
Trustee nor the Collateral Agent shall be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved in a court of competent jurisdiction that the Trustee or the Collateral Agents was negligent in ascertaining the
pertinent facts; and 
 (3) neither the Trustee nor the Collateral Agent shall be liable with respect to any
action it takes or omits to take in good faith in accordance with a direction received by it pursuant to the terms hereof. 

(d) Whether or not therein expressly so provided, every provision of this Indenture, the Collateral Agreements and the Intercreditor
Agreements, as applicable, that in any way relates to the Trustee or the Collateral Agent is subject to clauses (a), (b) and (c) of this Section 7.01. 
 (e) Neither the Trustee nor the Collateral Agent shall be under any obligation to exercise any of its rights or powers under this Indenture, the Collateral Agreements and the Intercreditor Agreements at
the request or direction of any of the Holders of the Notes unless the Holders have offered to the Trustee or the Collateral Agent, as applicable, indemnity or security satisfactory to the Trustee against any loss, liability or expense. 

(f) Neither the Trustee nor the Collateral Agent shall be liable for interest on any money received by it except as the Trustee or the
Collateral Agent may agree in writing with the Issuer. Money held in trust by the Trustee or the Collateral Agent need not be segregated from other funds except to the extent required by law. 

Section 7.02   Rights of Trustee and the Collateral Agent. 

Subject to the provisions of Section 7.01 hereof: 
 (a) Each of the Trustee and the Collateral Agent may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. Neither the Trustee nor the
Collateral Agent need investigate any fact or matter stated in the document, but the Trustee and the Collateral Agent, as applicable, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee or the Collateral Agent, as applicable, shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the sole
cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. Any permissive right or authority granted to the Trustee or the Collateral Agent shall not be construed as a mandatory
duty. 

  
 94 

 (b) Before the Trustee or the Collateral Agent acts or refrains from acting, it may require
an Officers’ Certificate or an Opinion of Counsel or both subject to the other provisions of this Indenture. Neither the Trustee nor the Collateral Agent shall be liable for any action it takes or omits to take in good faith in reliance on such
Officer’s Certificate or Opinion of Counsel. The Trustee and the Collateral Agent may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from
liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 
 (c) Each
of the Trustee and the Collateral Agent may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care. 

(d) Neither the Trustee nor the Collateral Agent shall be liable for any action it takes or omits to take in good faith that it
reasonably believes to be authorized or within the rights or powers conferred upon it by this Indenture, the Collateral Agreements or the Intercreditor Agreements. 
 (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if signed by an Officer of the Issuer. Neither the Trustee nor
the Collateral Agent shall have any duty to inquire as to the performance of the Issuer’s or any Subsidiary Guarantor’s covenants herein. 
 (f) None of the provisions of this Indenture, the Collateral Agreements or the Intercreditor Agreements shall require the Trustee or the Collateral Agent to expend or risk its own funds or otherwise to
incur any liability, financial or otherwise, in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or indemnity
satisfactory to it against such risk or liability is not assured to it. 
 (g) Neither the Trustee nor the Collateral Agent
shall be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee or the Collateral Agent, as applicable, has actual knowledge thereof or unless written notice of any event which is in fact such a Default is
received by the Trustee or the Collateral Agent, as applicable, at the Corporate Trust Office of the Trustee or the Collateral Agent, as applicable, and such notice references the existence of a Default or Event of Default, the Notes and this
Indenture. 
 (h) In no event shall the Trustee or the Collateral Agent be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee or the Collateral Agent has been advised of the likelihood of such loss or damage and regardless of the form of
action. 
 (i) The rights, privileges, protections, immunities and benefits given to each of the Trustee and the Collateral
Agent, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, each of the Trustee and the Collateral Agent in each of its capacities hereunder and under the Collateral Agreements and the
Intercreditor Agreements, and by each agent, custodian and other Person employed to act hereunder or thereunder. 

  
 95 

 (j) Neither the Trustee nor the Collateral Agent shall be required to give any bond or
surety in respect of the performance of its powers or duties. 
 (k) The Trustee and the Collateral Agent may request that the
Issuer deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, the Collateral Agreements and the Intercreditor Agreements,
which Officers’ Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

(l) The permissive rights of the Trustee and the Collateral Agent enumerated herein shall not be construed as duties. 

Section 7.03   Individual Rights of Trustee and the Collateral Agent. 

The Trustee or the Collateral Agent in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise
deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee or the Collateral Agent. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and
7.11 hereof. 
 Section 7.04   Disclaimer. 

Neither the Trustee nor the Collateral Agent shall be responsible for and makes no representation as to the validity or adequacy of this
Indenture, the Notes, the Collateral Agreements or the Intercreditor Agreements, it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any
provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee or the Collateral Agent, as the case may be, and it shall not be responsible for any statement or
recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 

Section 7.05   Notice of Default. 
 If a Default occurs and is continuing and if it is actually known to a Trust Officer of the Trustee, the Trustee shall mail or electronically transmit to Holders of Notes a notice of the Default within
the earlier of ninety (90) days after it occurs or thirty (30) days after it is actually known to a Trust Officer or written notice of it is received by the Trustee. Except in the case of a Default relating to the payment of principal,
premium, if any, or interest on any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of the
Holders of the Notes. The Trustee shall not be deemed to know of any Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the
Corporate Trust Office of the Trustee and references a Default or Event of Default. 

  
 96 

 Section 7.06   Compensation and Indemnity. 

The Issuer and the Subsidiary Guarantors, jointly and severally, shall pay to the Trustee and the Collateral Agent from time to time such
compensation for its acceptance of this Indenture and services hereunder and under the Collateral Agreements and the Intercreditor Agreements as the parties shall agree in writing from time to time. Neither the Trustee’s or the Collateral
Agent’s compensation shall be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee and the Collateral Agent promptly upon request for all reasonable disbursements, advances, expenses,
claims and damages incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s and the Collateral Agent’s agents and counsel.

 The Issuer and the Subsidiary Guarantors, jointly and severally, shall indemnify each of the Trustee, any predecessor
Trustee, the Collateral Agent and any predecessor Collateral Agent and their agents for, and hold the Trustee and the Collateral Agent harmless against, any and all loss, damage, claims, liability or expense (including attorneys’ fees and
including taxes (other than taxes based upon, measured by or determined by the income of the Trustee and the Collateral Agent)) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties
hereunder and under the Collateral Agreements and the Intercreditor Agreements (including the costs and expenses of enforcing this Indenture, the Collateral Agreements and the Intercreditor Agreements against the Issuer or any of the Subsidiary
Guarantors (including this Section 7.06) or defending itself against any claim whether asserted by any Holder, the Issuer, any Subsidiary Guarantor or any other Person, or liability in connection with the acceptance, exercise or
performance of any of its powers or duties hereunder). Each of the Trustee and the Collateral Agent shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee or the Collateral Agent to so notify the Issuer
shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee and the Collateral Agent may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not
reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee or the Collateral Agent through the Trustee’s or the Collateral Agent’s own willful misconduct, negligence or bad faith. 

The obligations of the Issuer under this Section 7.06 shall survive the satisfaction and discharge of this Indenture,
including any termination or rejection hereof under the Bankruptcy Code or any similar Federal or state law for the relief of debtors, or the earlier resignation or removal of the Trustee or the Collateral Agent. 

To secure the payment obligations of the Issuer and the Subsidiary Guarantors in this Section 7.06, the Trustee and the
Collateral Agent shall have a Lien prior to the Notes on all money or property held or collected by the Trustee and the Collateral Agent, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture. 

  
 97 

 When the Trustee or the Collateral Agent incurs expenses or renders services after an Event
of Default specified in Section 6.01(a)(6) or (7) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of
administration under the Bankruptcy Code or any similar Federal or state law for the relief of debtors. 

Section 7.07  Replacement of Trustee or Collateral Agent. 

A resignation or removal of the Trustee or the Collateral Agent and appointment of a successor Trustee or a successor Collateral Agent
shall become effective only upon the successor Trustee’s or successor Collateral Agent’s acceptance of appointment as provided in this Section 7.07. The Trustee or the Collateral Agent may resign in writing at any time and be
discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee or the Collateral Agent by so notifying the Trustee or the Collateral Agent, as
the case may be, and the Issuer in writing. The Issuer may remove the Trustee or the Collateral Agent if: 
 (1)
in the case of the Trustee, the Trustee fails to comply with Section 7.09 hereof; 
 (2) the Trustee
or the Collateral Agent, as the case may be, is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under the Bankruptcy Code or any similar Federal or state law for the relief of debtors; 

(3) a custodian or public officer takes charge of the Trustee or the Collateral Agent, as the case may be, or its
property; or 
 (4) the Trustee or the Collateral Agent becomes incapable of acting. 

If the Trustee or the Collateral Agent resigns or is removed or if a vacancy exists in the office of Trustee or the Collateral Agent for
any reason, the Issuer shall promptly appoint a successor Trustee or a successor Collateral Agent, as the case may be. Within one year after the successor Trustee or successor Collateral Agent takes office, the Holders of a majority in principal
amount of the then outstanding Notes may appoint a successor Trustee or a successor Collateral Agent to replace the successor Trustee or successor Collateral Agent appointed by the Issuer. 

If a successor Trustee or a successor Collateral Agent does not take office within sixty (60) days after the retiring Trustee or
Collateral Agent resigns or is removed, the retiring Trustee or Collateral Agent (at the Issuer’s expense), the Issuer or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee or successor Collateral Agent, as the case may be. 
 If the Trustee,
after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor Trustee. 

  
 98 

 A successor Trustee or successor Collateral Agent shall deliver a written acceptance of its
appointment to the retiring Trustee or Collateral Agent and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee or Collateral Agent shall become effective, and the successor Trustee or Collateral Agent shall have all the
rights, powers and duties of the Trustee or Collateral Agent under this Indenture. The successor Trustee or successor Collateral Agent shall mail a notice of its succession to Holders. The retiring Trustee or Collateral Agent shall promptly transfer
all property held by it as Trustee or Collateral Agent to the successor Trustee or successor Collateral Agent; provided all sums owing to the Trustee or the Collateral Agent hereunder have been paid and subject to the Lien provided for in
Section 7.06 hereof. Notwithstanding replacement of the Trustee or the Collateral Agent pursuant to this Section 7.07, the Issuer’s obligations under Section 7.06 hereof shall continue for the benefit of the
retiring Trustee or Collateral Agent. 
 Section 7.08  Successor by Merger, Etc. 

If the Trustee or the Collateral Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate
trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee or successor Collateral Agent. 
 Section 7.09  Eligibility; Disqualification. 
 There
will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is
subject to supervision or examination by Federal or state authorities and that has a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition. 

Section 7.10  Trustee as Paying Agent and Registrar. 

References to the Trustee in Sections 7.01(f), 7.02, 7.03, 7.04, 7.06, 7.07 and
Section 7.09 shall include the Trustee in its role as Paying Agent and Registrar. 

Section 7.11  Form of Documents Delivered to Trustee and the Collateral Agent. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary
that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more
other Persons as to other matters and any such Person may certify or give an opinion as to such matters in one or several documents. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be
consolidated and form one instrument. 

  
 99 

 ARTICLE VIII 
 DEFEASANCE 
 Section 8.01  Defeasance.

 (a) Subject to Sections 8.01(b) and 8.02 hereof, the Issuer at any time may, at its option, terminate
(i) all its obligations under the Notes, this Indenture and the Collateral Agreements and all obligations of the Subsidiary Guarantors under the Subsidiary Guarantees, this Indenture and the Collateral Agreements (“legal defeasance
option”) or (ii) its obligations and all obligations of the Subsidiary Guarantors under Section 4.04, Section 4.06, Sections 4.08 through 4.23 and the operation of Sections 6.01(4),
6.01(5), 6.01(6) (but only with respect to Significant Subsidiaries), 6.01(7) (but only with respect to Significant Subsidiaries), 6.01(8) and 6.01(11) and its obligations under Section 5.01(a)(3)
hereof (“covenant defeasance option”) and thereafter any omission to comply with those covenants or obligations will not constitute a Default or Event of Default with respect to the Notes. In the event the covenant defeasance option
occurs, all Events of Default described under Section 6.01 (except Sections 6.01(1), 6.01(2), 6.01(6) and 6.01(7)) will no longer constitute an Event of Default with respect to the Notes. 

The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Issuer
exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. If the Issuer exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an
Event of Default specified in Section 6.01(4), 6.01(5), 6.01(6) (but only with respect to Significant Subsidiaries), 6.01(7) (but only with respect to Significant Subsidiaries) or 6.01(8) or because of the
failure of the Issuer to comply with Section 5.01(a)(3) hereof. If the Issuer exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor shall be released from all its obligations with respect to
its Subsidiary Guarantee. 
 Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee
shall acknowledge in writing the discharge of those obligations that the Issuer terminates. 
 (b) Notwithstanding clauses
(a) and (b) above, the Issuer’s obligations in Sections 2.03, 2.04, 2.05, 2.07, 7.07, 7.08 and this Article VIII shall survive until the Notes have been paid in full. Thereafter,
the Issuer’s obligations in Sections 7.07, 8.03 and 8.04 shall survive. 

Section 8.02  Conditions to Defeasance. 

The Issuer may exercise its legal defeasance option or its covenant defeasance option only if: 

(1) the Issuer irrevocably deposits in trust with the Trustee U.S. Legal Tender or U.S. Government Obligations, or a
combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent accountants, to pay the principal and interest when due on all the Notes to the Maturity Date or the Redemption Date, as the
case may be; 

  
 100

 (2) [Reserved]; 

(3) No Default or Event of Default (other than a Default or Event of Default resulting from the borrowing of funds to be
applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of any Lien securing such borrowings) shall have occurred and be continuing on the date of such deposit; 

(4) such legal defeasance option or covenant defeasance option shall not constitute a default under any material agreement
or instrument (other than this Indenture) by which the Issuer is bound; 
 (5) in the case of the legal
defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this
Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders shall not recognize income, gain or loss for Federal income tax
purposes as a result of such deposit and legal defeasance and shall be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred; 

(6) in the case of the covenant defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel
confirming that the Holders of the respective outstanding Notes shall not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and covenant defeasance and shall be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and 
 (7) the Issuer delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions), each stating that all
conditions precedent relating to the legal defeasance or covenant defeasance have been complied with. 
 Before or after a
deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of Notes at a future date in accordance with Article III. 
 Section 8.03  Application of Trust Money. 
 The
Trustee shall hold in trust U.S. Legal Tender or U.S. Government Obligations deposited with it pursuant to this Article VIII. It shall apply the deposited U.S. Legal Tender and the U.S. Legal Tender from U.S. Government Obligations through
the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Notes. 

Section 8.04  Repayment to Issuer. 

  
 101

 The Trustee and the Paying Agent shall promptly turn over to the Issuer upon request any
money or securities held by them at any time which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that
would then be required for the Issuer to exercise its legal defeasance option or its covenant defeasance option pursuant to this Article VIII. 
 Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Issuer upon written request any money held by them for the payment of principal or interest that remains
unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Issuer for payment as general creditors. 
 Section 8.05  Indemnity for Government Obligations. 

The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or the principal and interest received on such U.S. Government Obligations other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 

Section 8.06  Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with this Article VIII 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 Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in accordance with this Article VIII; provided, however, that,
if the Issuer has made any payment of interest on, premium, if any, or principal of any Notes following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the
U.S. Legal Tender or U.S. Government Obligations held by the Trustee or Paying Agent. 
 ARTICLE IX 

AMENDMENTS, SUPPLEMENTS AND WAIVERS 
 Section 9.01  Without Consent of Holders. 
 (a) From
time to time, the Issuer, the Subsidiary Guarantors, the Trustee and, if such amendment, modification or supplement relates to any Collateral Agreement, the Collateral Agent, without the consent of any Holder of the Notes, may amend, modify or
supplement the Indenture Documents: 
 (1) to cure any ambiguity, defect or inconsistency; 

(2) to provide for the assumption of the Issuer’s or a Subsidiary Guarantor’s obligations to Holders of Notes
and Subsidiary Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s or such Subsidiary Guarantor’s assets, as applicable; 

  
 102

 (3) to provide for uncertificated Notes in addition to or in place of
certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);

 (4) to add guarantees with respect to the Notes (including any Subsidiary Guarantee); 

(5) if necessary, in connection with any addition or release of Collateral permitted under the terms of this Indenture or
the Collateral Agreements; 
 (6) to add to the covenants of the Issuer for the benefit of the Holders or
surrender any right or power conferred upon the Issuer or the Subsidiary Guarantors; 
 (7) to make any change
that does not adversely affect the rights of any Holder of the Notes; 
 (8) to conform this Indenture, the
Notes, the Subsidiary Guarantees or the Collateral Agreements to the “Description of the Notes” section of the Offering Memorandum; 
 (9) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date; or 

(10) to release a Subsidiary Guarantor of the Notes upon its sale or designation as an Unrestricted Subsidiary or other
permitted release from its Guarantee; provided that such sale, designation or release is in accordance with the applicable provisions of this Indenture. 
 Section 9.02  With Consent of Holders. 
 (a) Except
as provided below in this Section 9.02, from time to time, the Issuer, the Subsidiary Guarantors, the Trustee and, if such amendment, modification or supplement relates to any Collateral Agreement, the Collateral Agent, with the written
consent of the Holder or Holders of a majority in aggregate principal amount of the Notes then outstanding (including Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender
offer or exchange offer for, or purchase of, the Notes), may amend, modify or supplement the Indenture Documents and waive any existing Default or Event of Default or compliance with any provision of the Indenture Documents. 

(b) Without the consent of each Holder of an outstanding Note affected thereby, an amendment or waiver may not (with respect to any Notes
held by a non-consenting Holder): 
 (1) reduce the principal amount of Notes whose Holders must consent to an
amendment, supplement or waiver of any provision of the Indenture Documents; 
 (2) reduce the rate of or extend
the time for payment of interest on any Note; 

  
 103

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

 (4) reduce the premium payable upon a required purchase (to the extent the Issuer has at the time become
obligated by the terms of this Indenture to effect a required purchase), or the redemption of any Note or change the time at which any Note may be redeemed pursuant to Section 3.01 hereof; 

(5) make any Note payable in money other than that stated in the Note; 

(6) make any change in the provisions of this Indenture that impair the right of any Holder of the Notes to receive
payment of principal of and interest on such Holder’s Notes on or after the due dates therefor; 
 (7) make
any change in the amendment provisions which require each Holder’s consent or in the waiver provisions; 

(8) make the Notes or the Subsidiary Guarantees subordinated in right of payment to any other obligation; 

(9) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on, the Notes
(except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); 

(10) release any Subsidiary Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except
in accordance with the terms of this Indenture; or 
 (11) modify the provisions of the Indenture Documents
dealing with the application of proceeds of the Collateral in any manner that would adversely affect the Holders of the Notes in any material respect. 
 (c) In addition, no amendment, modification, supplement or waiver, including a waiver pursuant to Section 6.04 hereof, shall, without the consent of the Holders of at least 66 2/3% in principal amount of the then outstanding Notes issued under this Indenture, release all or substantially all of the Collateral otherwise than in accordance with the terms of this Indenture and the
Collateral Agreements. 
 (d) The consent of the Holders of the Notes shall not be necessary under this
Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

(e) After an amendment under this Section 9.02 becomes effective, the Issuer shall mail to Holders a notice briefly
describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02. 

  
 104

 Section 9.03  Revocation and Effect of Consents. 

Until an amendment, waiver or supplement becomes effective (which may be prior to any such amendment, waiver or supplement becoming
operative), a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made
on any Note. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by written notice to the Trustee and the Issuer received before the date on which the
Trustee and if such amendment, waiver or supplement relates to any Collateral Agreement, the Collateral Agent, receives written consents from the Holders of a requisite percentage in principal amount of the outstanding Notes or receives an
Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, waiver or supplement shall become
effective upon receipt by the Trustee or the Collateral Agent, as the case may be, of written consents from the Holders of the requisite percentage in principal amount of the outstanding Notes or such Officers’ Certificate, whichever first
occurs, and the execution thereof by the Trustee or the Collateral Agent, as the case may be. 
 The Issuer may, but shall not
be obligated to, fix a Record Date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a Record Date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Holders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such Record Date. No such
consent shall be valid or effective for more than 120 days after such Record Date. 

Section 9.04  Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about the changed terms on any Note thereafter authenticated. Alternatively, if the Issuer
so determines, the Issuer in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Any such notation or exchange shall be made at the sole cost and expense of the Issuer. Failure to make the
appropriate notation or issue a new Note shall not effect the validity and effect of such amendment, supplement or waiver. 

Section 9.05  Trustee and Collateral Agent to Sign Amendments, Etc. 

The Trustee and/or the Collateral Agent, as applicable, shall execute any amendment, supplement or waiver authorized pursuant to this
Article IX; provided that the Trustee or the Collateral Agent, as the case may be, may, but shall not be obligated to, execute any such amendment, supplement or waiver which adversely affects the rights, duties or immunities of the
Trustee or the Collateral Agent, as the case may be, under this Indenture or any Collateral Agreement. The Trustee or the Collateral Agent, as the case may be, shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel and an Officers’ Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture. Such Opinion of Counsel shall not be an
expense of the Trustee or the Collateral Agent, as the case may be, and shall be paid for by the Issuer. 

  
 105

 Notwithstanding the foregoing, no Opinions of Counsel will be required for the Trustee or
the Collateral Agent to execute any amendment or supplement adding a new Subsidiary Guarantor under this Indenture. 
 ARTICLE
X 
 GUARANTEE 
 Section 10.01  Guarantee. 
 Subject to this
Article X, each Subsidiary Guarantor hereby fully and unconditionally, jointly and severally guarantees on a senior secured basis (each such guarantee, as amended or supplemented from time to time, to be referred to herein as a
“Subsidiary Guarantee”), to each of the Holders and their respective successors and assigns that (i) the principal of, premium, if any and interest on the Notes shall be promptly paid in full when due, subject to any applicable
grace period, whether upon redemption pursuant to the terms of the Notes, by acceleration or otherwise, and interest on the overdue principal (including interest accruing at the then applicable rate provided in this Indenture after the occurrence of
any Event of Default set forth in Section 6.01(6) or (7), whether or not a claim for post-filing or post-petition interest is allowed under applicable law following the institution of a proceeding under bankruptcy, insolvency or
similar laws), if any, and interest on any interest, to the extent lawful, of the Notes and all other obligations of the Issuer to the Holders, the Trustee and the Collateral Agent hereunder, thereunder or under any other Indenture Document shall be
promptly paid in full or performed, all in accordance with the terms hereof, thereof and of the other Indenture Documents; and (ii) in case of any extension of time of payment or renewal of any of the Notes or of any such other obligations, the
same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise, subject, however, in the case of
clauses (i) and (ii) above, to the limitations set forth in this Section 10.01 and Section 10.03 hereof. The Guarantee of each Subsidiary Guarantor shall rank senior in right of payment to all future Subordinated
Obligations of such Subsidiary Guarantor and equal in right of payment with all other existing and future senior Obligations of such Subsidiary Guarantor. Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes, this Indenture or any other Indenture Documents, the absence of any action to enforce the same, any waiver or consent by any of the Holders with respect to any provisions
hereof or thereof, any release of any other Subsidiary Guarantor, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of
a Subsidiary Guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the
Issuer, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and in this Subsidiary Guarantee. 

  
 106

 The obligations of each Subsidiary Guarantor are limited to the maximum amount which, after
giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other
Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, shall result in the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under Federal or state law. The net worth of any Subsidiary Guarantor for such purpose shall include any claim of such Subsidiary Guarantor against the Issuer for reimbursement and any claim against any other
Subsidiary Guarantor for contribution. Each Subsidiary Guarantor may consolidate with, merge with or into, or transfer all or substantially all its assets to any other Person to the extent permitted under Section 5.01 hereof;
provided, however, that if such Person is not the Issuer, the Subsidiary Guarantor’s obligations under this Indenture and its Subsidiary Guarantee must be expressly assumed by such other Person. If any Holder, the Collateral Agent
or the Trustee is required by any court or otherwise to return to the Issuer, any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Subsidiary Guarantor, any amount paid by
the Issuer or any Subsidiary Guarantor to the Trustee, the Collateral Agent or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor further agrees that, as between
each Subsidiary Guarantor, on the one hand, and the Holders, the Collateral Agent and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of
this Guarantee notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article
VI, such obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of this Subsidiary Guarantee. 
 Section 10.02  Release of a Subsidiary Guarantor. 

(a) A Subsidiary Guarantor shall be automatically and unconditionally released from its Guarantee without any action required on the part
of the Trustee or any Holder: 
 (1) if (a) all of the Capital Stock issued by such Subsidiary Guarantor or
all or substantially all of the assets of such Subsidiary Guarantor are sold or otherwise disposed of (including by way of merger or consolidation) to a Person other than the Issuer or any other Subsidiary Guarantor or (b) such Subsidiary
Guarantor ceases to be a Restricted Subsidiary, and the Issuer otherwise complies, to the extent applicable, with Section 4.11 hereof; 
 (2) if the Issuer designates such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture; 

(3) if the Issuer exercises its legal defeasance option or its covenant defeasance option in accordance with
Section 8.01 hereof; or 
 (4) upon satisfaction and discharge of this Indenture in accordance with
Section 11.01 hereof or payment in full in cash of the principal of, premium, if any, accrued and unpaid interest on the Notes and all other Obligations that are then due and payable. 

  
 107

 At the Issuer’s request and expense, the Trustee will promptly execute and deliver an
instrument evidencing such release. A Subsidiary Guarantor may also be released from its obligations under its Guarantee in connection with a permitted amendment of this Indenture. 

Section 10.03  Limitation of Subsidiary Guarantor’s Liability. 

Each Subsidiary Guarantor and, by its acceptance hereof, each of the Holders hereby confirms that it is the intention of all such parties
that the guarantee by such Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar Federal or state law. To effectuate the foregoing intention, the Holders and such Subsidiary Guarantor hereby irrevocably agree that the obligations of such Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as
shall, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of
such other Subsidiary Guarantor under its Guarantee or pursuant to Section 10.04 hereof, result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting such fraudulent transfer or conveyance. 

Section 10.04  Contribution. 
 In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that each Subsidiary Guarantor that makes a payment or
distribution under a Guarantee shall be entitled to a pro rata contribution from each other Subsidiary Guarantor hereunder based on the net assets of each other Subsidiary Guarantor and the Issuer. The preceding sentence shall in no way affect the
rights of the Holders to the benefits of this Indenture, the Notes or the Subsidiary Guarantees. 

Section 10.05  Waiver of Subrogation. 

Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 

Section 10.06  Waiver of Stay, Extension or Usury Laws. 

Each Subsidiary Guarantor covenants to the extent permitted by law that it shall not at any time insist upon, plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law that would prohibit or forgive such Subsidiary Guarantor from performing its Guarantee as contemplated herein, wherever enacted, now or at any time
hereafter in force; and each Subsidiary Guarantor hereby expressly waives to the extent permitted by law all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to
the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 

  
 108

 Section 10.07  Execution and Delivery of Subsidiary Guarantees.

 Each Subsidiary Guarantor hereby agrees that its execution and delivery of this Indenture or any supplemental indenture
substantially in the form of Exhibit E hereto executed on behalf of such Subsidiary Guarantor by an Officer thereof in accordance with Section 4.16 hereof shall evidence its Subsidiary Guarantee set forth in this Article X
without the need for any further notation on the Notes. 
 ARTICLE XI 

SATISFACTION AND DISCHARGE. 
 Section 11.01  Satisfaction and Discharge. 
 This
Indenture (and all Liens on Collateral in connection with the issuance of the Notes) shall be discharged and shall cease to be of further effect as to all Notes issued hereunder, when: 

(a) either: 
 (1) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment U.S. Legal Tender has been deposited in trust and thereafter
repaid to the Issuer, have been delivered to the Trustee for cancellation; or 
 (2) all Notes that have not been
delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable by reason of the mailing of a notice of redemption or otherwise within one year and
the Issuer or any Subsidiary Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, U.S. Legal Tender, U.S. Government Obligations, or a combination thereof, in
amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal of, premium on, if any, and interest, if any,
on, the Notes to the Maturity Date or the Redemption Date; 
 (b) in respect of clause (a)(2), no Default or Event of Default
has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the
granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer is a party or by which the Issuer is bound (other than with respect to
the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such
borrowings); 
 (c) the Issuer or any Subsidiary Guarantor has paid or caused to be paid all sums payable by it under the
Indenture Documents; and 

  
 109

any Collateral from the terms of the Collateral Agreements shall not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Collateral is released pursuant to this Indenture and the
Collateral Agreements. 
 Notwithstanding any provision to the contrary herein, Collateral comprised of accounts receivable, and

the Liens securing its Guarantee and the other Indenture Obligations; 
 (4) with respect to any property and
assets owned by the Issuer or any Subsidiary Guarantor that are the subject of Permitted Liens described in clause (10) or (11) of the definition thereof so long as such Permitted Liens are in effect and the Indebtedness secured thereby
otherwise prohibits any other Liens thereon or creates a right of termination in favor of any party (other than the Issuer or any Subsidiary Guarantor); 
 (5) if such release is required in accordance with the terms of the Intercreditor Agreement or any Collateral Agreements; or 

(6) upon legal defeasance or covenant defeasance or satisfaction and discharge of this Indenture.

subordination prepared by the Issuer, the Collateral Agent shall execute, deliver or acknowledge such instruments or releases as the Issuer or any Subsidiary Guarantor may reasonably request to evidence the release of any Collateral or the
Subordination of any Lien on the Collateral permitted to be released or subordinated pursuant to this Indenture or the Collateral Agreements. 
 Section 13.05  Release upon Satisfaction or Defeasance of All Outstanding Obligations.

discharge of this Indenture as described above under Section 11.01 and (iii) the occurrence of the legal defeasance option or the covenant defeasance option as described above under Section 8.01.

interest, rents, lease payments, issues, profits, revenues, proceeds and other income thereof. 

Section 13.07  Form and Sufficiency of Release.

otherwise dispose of any portion of the Collateral that may be sold, exchanged or otherwise disposed of by the Issuer or such Subsidiary Guarantor to a Person other than the Issuer or any Subsidiary Guarantor in accordance with the terms of this
Indenture and the Collateral Agreements, and the Issuer or such Subsidiary Guarantor requests in writing the Collateral Agent to furnish a written disclaimer, release or quit-claim of any interest in such property under this Indenture and the
Collateral Agreements, the Collateral Agent shall execute, acknowledge and deliver to the Issuer such Subsidiary Guarantor (in proper form prepared by the Issuer or such Subsidiary Guarantor) such an instrument promptly after receipt of an
Officers’ Certificate to the extent that such release complies with Section 13.04 hereof (upon which the Trustee and the Collateral Agent may exclusively and conclusively rely). Notwithstanding the preceding sentence, all purchasers
and grantees of any property or rights purporting to be released herefrom shall be entitled to rely upon any release executed by the Collateral Agent hereunder as sufficient for the purpose of this Indenture and as constituting a good and valid
release of the property therein described from the Lien of this Indenture or of the Collateral Agreements. 

Section 13.08  Purchaser Protected.

Trustee or the Collateral Agent to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority; nor shall any purchaser or grantee of any property or rights permitted by this Indenture

terms of the Collateral Agreements and (ii) collect and receive any and all amounts payable in respect of the Obligations of the Issuer and the Subsidiary Guarantors hereunder and under the Notes, the Guarantees and the Collateral Agreements

unlawful or in violation of the Collateral Agreements or this Indenture, and suits and proceedings as the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Trustee and the Holders in the Collateral

of, or compliance with, such enactment, rule or order would impair the security interest thereunder or be prejudicial to the interests of the Collateral Agent, the Holders or the Trustee). Notwithstanding the foregoing, the Collateral Agent may, at
the expense of the Issuer, request the direction of the Holders with respect to any such actions and upon receipt of the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes, shall take such
actions; provided that all actions so taken shall, at all times, be in conformity with the requirements of the applicable Intercreditor Agreements, to the extent the Intercreditor Agreements are applicable to such actions.

INMETCO Collateral pursuant to the Indenture Documents for the period and to the extent granted therein and to receive a share of the proceeds thereof, if any, after the Discharge of INMETCO Facility Claims has occurred. 

(c) Subject to the first proviso to the first sentence of Section 3.1(a) above and without limiting the effect of other
provisions of this Agreement, (i) the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, agrees that the Collateral Agent, the Trustee and the other Indenture Holders will not take any action that would hinder
any exercise of remedies undertaken by the INMETCO Agent under the INMETCO Facility Documents with respect to the INMETCO Collateral, including any sale, lease, exchange, transfer or other disposition of the INMETCO Collateral, whether by
foreclosure or otherwise, and (ii) the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, hereby waives any and all rights it or the other Indenture Holders may have as a junior lien creditor to object to the
manner in which the INMETCO Agent or the INMETCO Facility Lenders seek to enforce or collect the INMETCO Facility Claims or the Liens granted in any INMETCO Collateral, regardless of whether any action or failure to act by or on behalf of the
INMETCO Agent or INMETCO Facility Lenders is adverse to the interest of the Indenture Holders. 
 (d) The Collateral Agent, on
behalf of itself, the Trustee and the other Indenture Holders, hereby acknowledges and agrees that no covenant, agreement or restriction contained in any Indenture Document shall be deemed to restrict in any way the rights and remedies of the
INMETCO Agent or the INMETCO Facility Lenders with respect to the INMETCO Collateral as set forth in this Agreement and the INMETCO Facility Documents.

 3.2 Cooperation. 

Subject to the first proviso to the first sentence of Section 3.1(a) above, the Collateral Agent, on behalf of itself, the
Trustee and the other Indenture Holders, agrees that, unless and until the Discharge of INMETCO Facility Claims has occurred, it will not commence, or join with any Person (other than the INMETCO Facility Lenders and the INMETCO Agent upon the
request thereof) in commencing, any enforcement, collection, execution, levy or foreclosure action or proceeding with respect to any Lien held by it in any INMETCO Collateral under any of the Indenture Documents or otherwise. 

SECTION 4. Payments. 

4.1 Application of Proceeds. So long as the Discharge of INMETCO Facility Claims has not occurred, the INMETCO Collateral or
proceeds thereof (or amounts in respect thereof) received in connection with the sale or other disposition of, or collection on, such INMETCO Collateral upon the exercise of remedies (or in respect of any INMETCO Collateral in the event of the
occurrence of an Insolvency or Liquidation Proceeding with respect to a Grantor), shall be applied: 
 (i) first, to the
payment of the costs and expenses incurred by the INMETCO Agent or the Collateral Agent, as the case may be, in connection with such sale or other disposition or collection until all such costs and expenses shall have been paid in full in cash;

 (ii) second, by the INMETCO Agent to the INMETCO Facility Claims (other than Excess INMETCO Facility Claims) in such
order as specified in the relevant INMETCO Facility Documents (or, if an order is not specified in the INMETCO Facility Documents, in such order determined by the INMETCO Agent in its sole discretion) until the Discharge of INMETCO Facility Claims
(other than Excess INMETCO Facility Claims) has occurred; 
 (iii) third, by the Collateral Agent to the Indenture
Obligations (other than Excess Indenture Obligations) in such order as specified in the Indenture (or if an order is not specified in the Indenture, in such order determined by the Trustee acting at the direction of the requisite Indenture Holders)
until the Discharge of Indenture Obligations (other than Excess Indenture Obligations) has occurred; 
 (iv) fourth, by
the INMETCO Agent to the Excess INMETCO Facility Claims; 
 (v) fifth, by the Collateral Agent to the Excess Indenture
Obligations; and

entitled to receive the same or as a court of competent jurisdiction may direct, of any surplus then remaining from such proceeds. 
 4.2 Payments Over . Any INMETCO Collateral or proceeds thereof (or amounts in respect thereof) received by the Collateral Agent, the Trustee or any other Indenture Holder in connection with the
exercise of any right or remedy (including set-off) relating to the INMETCO Collateral in contravention of this Agreement shall be segregated and held in trust and forthwith paid over to the INMETCO Agent for the benefit of itself and the INMETCO
Facility Lenders in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct. 

  
 G-12

 
The INMETCO Agent is hereby authorized to make any such endorsements as agent for the Collateral Agent, the Trustee or any such other Indenture Holder. This authorization is coupled with an
interest and is irrevocable. 
 SECTION 5. Other Agreements. 
 5.1 Releases in Respect of INMETCO Collateral. 
 (i) If in connection with:

 (A) the exercise of the INMETCO Agent’s remedies in respect of the INMETCO Collateral; or 

(B) any sale, lease, exchange, transfer or other disposition of any INMETCO Collateral that is permitted or not prohibited under
(i) the terms of the INMETCO Facility Documents (whether or not an “event of default” thereunder, and as defined therein, has occurred and is continuing) and (ii) the terms of the Indenture, the INMETCO Agent, for itself and on
behalf of the INMETCO Facility Lenders, releases any of its Liens on any part of the INMETCO Collateral, the Liens, if any, of the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, on such INMETCO Collateral shall
be automatically, unconditionally and simultaneously released and the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, promptly shall execute and deliver to the INMETCO Agent or the Issuer such termination
statements, releases and other documents as the INMETCO Agent or the Issuer may reasonably request to effectively confirm such release. 
 (ii) The Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, hereby irrevocably constitutes and appoints the INMETCO Agent and any officer or agent of the INMETCO Agent,
with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Collateral Agent or such holder or in the INMETCO Agent’s own name, from time to time in the
INMETCO Agent’s discretion, for the purpose of carrying out the terms of this Section 5.1, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish
the purposes of this Section 5.1, including any termination statements, endorsements or other instruments of transfer or release. 
 5.2 Insurance. Unless and until the Discharge of INMETCO Facility Claims has occurred, the INMETCO Agent and the INMETCO Facility Lenders shall have the sole and exclusive right under the INMETCO
Facility Documents, to the extent such a right is granted in the INMETCO Facility Documents, to settle and adjust settlement for any insurance policy covering the INMETCO Collateral in the event of any loss thereunder and to approve any award
granted in any condemnation or similar proceeding relating to the INMETCO Collateral. Unless and until the Discharge of INMETCO Facility Claims has occurred, all proceeds of any such policy and any such award if in respect to the INMETCO Collateral
shall be paid to the INMETCO Agent for the benefit of the INMETCO Facility Lenders to the extent required under the INMETCO Facility Documents and thereafter to the Collateral Agent for the benefit of the other Indenture Holders to the extent
required under the Indenture Documents and then to the owner of the subject property or as a court of competent jurisdiction may otherwise direct. If the Collateral Agent, the Trustee or any other Indenture Holder shall, at any time, receive any
proceeds of any such insurance policy or any such award in contravention of this Agreement, it shall pay such proceeds over to the INMETCO Agent in accordance with the terms of Section 4.2. 

5.3 Legend. 

  
 G-13

 The Collateral Agent agrees that the Indenture Collateral Document shall include the
following language (or (i) language to similar effect approved by the INMETCO Agent, or (ii) as revised to the extent necessary to properly refer to any amendment, restatement, replacement or other modification to this Agreement):

 “Notwithstanding anything herein to the contrary, the lien and security interest granted to the Collateral Agent pursuant
to this Agreement and the Indenture Collateral Documents and the exercise of any right or remedy by the Collateral Agent hereunder and thereunder are subject to the provisions of that certain Intercreditor Agreement, dated
[            ], 201[    ], by and between: (i) U.S. Bank National Association, as Collateral Agent (and its successors and assigns), for the benefit of the holders
from time to time of the Indenture Obligations (as defined therein) and (ii) [            ], as INMETCO Agent (and its successors and assigns), for the benefit of the holders from time
to time of the INMETCO Facility Claims (as defined therein) (as may be amended, restated, modified or supplemented or replaced, from time to time in accordance therewith, the “Intercreditor Agreement”). In the event of any conflict
between the terms of the Intercreditor Agreement and this Agreement with respect to lien priority or rights and remedies in connection with the INMETCO Collateral (as defined in the Intercreditor Agreement), the terms of the Intercreditor Agreement
shall govern.” 
 5.4 Rights As Unsecured Creditors. Notwithstanding anything to the contrary in this Agreement,
each of the Collateral Agent, the Trustee and the other Indenture Holders may exercise rights and remedies as an unsecured creditor against INMETCO or any other Grantor that has guaranteed the Indenture Obligations in accordance with the terms of
the Indenture Documents and applicable law. Nothing in this Agreement shall prohibit the receipt by the Collateral Agent, the Trustee or any other Indenture Holders of the required payments of interest, premium, if any, and principal on the
Indenture Obligations and related fees and expenses so long as such receipt is not the direct or indirect result of the exercise by the Collateral Agent, the Trustee or any other Indenture Holder of rights or remedies as a secured creditor or
enforcement in contravention of this Agreement of any Lien held by any of them in respect of any INMETCO Collateral (or received or paid in respect of any INMETCO Collateral in the event of the occurrence of an Insolvency or Liquidation Proceeding
with respect to a Grantor). In the event the Collateral Agent, the Trustee or any other Indenture Holder becomes a judgment lien creditor in respect of INMETCO Collateral as a result of its enforcement of its rights as an unsecured creditor, such
judgment lien shall be subordinated to the Liens securing INMETCO Facility Claims on the same basis as the other Liens securing the Indenture Obligations are so subordinated to such INMETCO Facility Claims under this Agreement. Nothing in this
Agreement shall impair or otherwise adversely affect any rights or remedies the INMETCO Agent or the INMETCO Facility Lenders may have with respect to the INMETCO Collateral. 
 5.5 Agent and Bailee for Perfection and Control. 
 (i) The INMETCO Agent
agrees to hold the Pledged Collateral that is part of the INMETCO Collateral in its possession or control (or in the possession or control of its agents or bailees) as agent and bailee for the Collateral Agent and any assignee solely for the purpose
of perfecting the security interest (or improving the priority thereof) granted in such Pledged Collateral pursuant to the Indenture Documents, subject to the terms and conditions of this Section 5.5. 

  
 G-14

 (ii) Until the Discharge of INMETCO Facility Claims has occurred, the INMETCO Agent shall be
entitled to deal with such Pledged Collateral in accordance with the terms of the INMETCO Facility Documents as if the Liens of the Collateral Agent under the Indenture Collateral Documents did not exist. The rights of the Collateral Agent shall at
all times be subject to the terms of this Agreement and, with respect to the INMETCO Collateral, to the INMETCO Agent’s rights under the INMETCO Facility Documents. 
 (iii) The INMETCO Agent shall have no obligation whatsoever to the Collateral Agent, the Trustee or any other Indenture Holder to assure that such Pledged Collateral is genuine or owned by any of the
Grantors or to preserve rights or benefits of any Person except as expressly set forth in this Section 5.5. The duties or responsibilities of the INMETCO Agent under this Section 5.5 shall be limited solely to holding such
Pledged Collateral as agent and bailee for the Collateral Agent for purposes of perfecting the Lien (or improving the priority thereof) held by the Collateral Agent. 
 (iv) The INMETCO Agent shall not have, by reason of the Indenture Collateral Documents or this Agreement or any other document, a fiduciary relationship in respect of the Collateral Agent, the Trustee or
any other Indenture Holder. 
 (v) Upon the Discharge of INMETCO Facility Claims, the INMETCO Agent shall deliver to the
Collateral Agent or, if applicable, cause the Collateral Agent to have control of such remaining Pledged Collateral (if any) (or the proceeds thereof) in its possession together with any necessary endorsements (or otherwise allow the Collateral
Agent, if applicable, to obtain control of such Pledged Collateral) or as a court of competent jurisdiction may otherwise direct. Such Pledged Collateral (if any) will be delivered or control in respect thereof will be made without recourse and
without any representation or warranty whatsoever as to the enforceability, perfection, priority or sufficiency of any Lien securing or guarantee or other supporting obligation for any Indenture Obligation, together with any necessary endorsements.

 (vi) Promptly upon the execution of this Agreement by the parties hereto, the Collateral Agent will, to the extent permitted
by applicable law, deliver to the INMETCO Agent any INMETCO Collateral in the possession or under the control of, the Collateral Agent, and all proceeds of INMETCO Collateral in the possession or under the control of the Collateral Agent, whether
arising out of the action taken to enforce, collect or realize upon any INMETCO Collateral or otherwise. Such INMETCO Collateral and such proceeds will be delivered without recourse and without any representation or warranty whatsoever as to the
enforceability, perfection, priority or sufficiency of any Lien securing or guarantee or other supporting obligation for any INMETCO Facility Claim, together with any necessary endorsements. 

5.6 Cooperation. 
 (a) Upon written request of the INMETCO Agent from time to time, the Collateral Agent, at the joint and several expense of the Grantors, shall promptly disclose to the INMETCO Agent all information in its
possession reasonably requested by the INMETCO Agent with respect to the INMETCO Collateral, including the identity of the Grantors and guarantors of any Indenture Obligations and the description, location and timing of perfection of Liens purported
to be created on the INMETCO Collateral to secure Indenture Obligations and shall promptly deliver to the INMETCO Agent copies of the Indenture Documents and other documents relating to the INMETCO Collateral, such as Uniform Commercial Code
Financing Statements and record copies of Indenture Collateral Documents. 

  
 G-15

 (b) Upon written request of the Collateral Agent from time to time, the INMETCO Agent, at
the joint and several expense of the Grantors, shall promptly disclose to the Collateral Agent all information in its possession reasonably requested by the Collateral Agent with respect to the INMETCO Collateral, including the identity of the
Grantors and guarantors of any INMETCO Facility Claims and the description, location and timing of perfection of Liens purported to be created on the INMETCO Collateral to secure INMETCO Facility Claims and shall promptly deliver to the Collateral
Agent copies of the INMETCO Facility Documents and other documents relating to the INMETCO Collateral, such as Uniform Commercial Code Financing Statements and record copies of INMETCO Facility Collateral Documents. 

(c) Neither the INMETCO Agent, nor any INMETCO Facility Lender, nor any of their respective officers, directors, employees, attorneys, or
agents are or will be responsible for the existence, genuineness, value or protection of any INMETCO Collateral, for the legality, enforceability, effectiveness or sufficiency of any Indenture Collateral Document, for the creation, perfection,
priority, sufficiency or protection of any Lien created under any Indenture Collateral Document or for any failure to demand, collect, foreclose or realize upon or otherwise enforce any Indenture Collateral Document or any Lien created thereunder,
or for any delay in doing so. Neither the Collateral Agent, nor the Trustee, nor any other Indenture Holder, nor any of their respective officers, directors, employees, attorneys, or agents are or will be responsible for the existence, genuineness,
value or protection of any INMETCO Collateral, for the legality, enforceability, effectiveness or sufficiency of any INMETCO Facility Collateral Document, for the creation, perfection, priority, sufficiency or protection of any Lien created under
any INMETCO Facility Collateral Document or for any failure to demand, collect, foreclose or realize upon or otherwise enforce any INMETCO Facility Collateral Document or any Lien created thereunder, or for any delay in doing so. 

SECTION 6. Insolvency or Liquidation Proceedings. 
 6.1 Financing Matters. 
 If any INMETCO Company shall be subject to any
Insolvency or Liquidation Proceeding and the INMETCO Agent shall desire to permit the use of cash collateral under Section 363 of Title 11 of the United States Code or any similar Bankruptcy Law or to permit any INMETCO Company to obtain
financing under Section 363 or Section 364 of Title 11 of the United States Code or any similar Bankruptcy Law (“DIP Financing”) in an aggregate principal amount that when taken together with the aggregate principal amount
of Indebtedness then outstanding under the Credit Agreement does not exceed the Maximum Credit Facility Principal Amount, then the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, agrees that it will raise no
objection to such use of cash collateral or DIP Financing and will not request adequate protection or any other relief in connection therewith (except to the extent permitted by Section 6.3) and, to the extent the Liens securing the
INMETCO Facility Claims are subordinated or pari passu with such DIP Financing, will subordinate its Liens in the INMETCO Collateral to such DIP Financing (and all Obligations relating thereto) on the same basis as the Liens on the INMETCO
Collateral that secure the Indenture Obligations are subordinated to the Liens thereon that secure the INMETCO Facility Claims under this Agreement, and agrees that notice received three (3) Business Days prior to the entry of an order
approving such usage of cash collateral or approving such financing on an interim basis shall be adequate notice; provided that the Collateral Agent, the Trustee and the other Indenture Holders retain the right to (i) object to any
ancillary agreements or arrangements regarding cash collateral use or the DIP Financing relating to any provision or content of plan of reorganization or similar dispositive restructuring plan that are materially prejudicial to the interests of the
Indenture Holders, (ii) object to any DIP Financing relating to any provision or content of a plan of reorganization or similar dispositive restructuring plan (other than to the extent requiring repayment in full of such DIP Financing) or
(iii) propose any other DIP Financing to such INMETCO Company or the bankruptcy court. 

  
 G-16

 6.2 Relief from the Automatic Stay. Until the Discharge of INMETCO Facility Claims
has occurred, the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, agrees that none of them shall seek relief from the automatic stay or any other stay in any Insolvency or Liquidation Proceeding in respect of the
INMETCO Collateral, without the prior written consent of the INMETCO Agent. 
 6.3 Adequate Protection. The Collateral
Agent, on behalf of itself, the Trustee and the other Indenture Holders, agrees that none of them shall, directly or indirectly, contest (or support any other Person contesting): (a) any request by the INMETCO Agent or the INMETCO Facility
Lenders for adequate protection; or (b) any objection by the INMETCO Agent or the INMETCO Facility Lenders to any motion, relief, action or proceeding based on the INMETCO Agent or the INMETCO Facility Lenders claiming a lack of adequate
protection, in each case, in respect of the INMETCO Collateral. Notwithstanding the foregoing contained in this Section 6.3, in any Insolvency or Liquidation Proceeding, (i) if the INMETCO Facility Lenders (or any subset thereof) are
granted adequate protection in the form of additional collateral from any Grantor in connection with any DIP Financing or use of cash collateral of any Grantor under Section 363 or Section 364 of Title 11 of the United States Code or any
similar Bankruptcy Law, then the Collateral Agent, on behalf of itself, the Trustee or any of the other Indenture Holders, may seek or request adequate protection in the form of a replacement Lien on such additional collateral, which Lien, if any,
shall be subordinated to the Liens securing the INMETCO Facility Claims and such DIP Financing (and all Obligations relating thereto) on the same basis as the other Liens on the INMETCO Collateral that secure the Indenture Obligations are so
subordinated to the Liens thereon that secure the INMETCO Facility Claims under this Agreement, and (ii) in the event the Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, seeks or requests adequate protection
and such adequate protection is granted in the form of additional collateral, then the Collateral Agent, on behalf of itself, the Trustee or any of the other Indenture Holders, agrees that the INMETCO Agent shall also be granted a senior Lien on
such additional collateral as security for the INMETCO Facility Claims and any such DIP Financing and that any Lien on such additional collateral securing the Indenture Obligations shall be subordinated to the Liens on such collateral securing the
INMETCO Facility Claims and any such DIP Financing (and all Obligations relating thereto) and any other Liens granted to the INMETCO Facility Lenders as adequate protection on the same basis as the other Liens on the INMETCO Collateral that secure
the Indenture Obligations are so subordinated to the Liens thereon that secure such INMETCO Facility Claims under this Agreement. 
 6.4 No Waiver. Nothing contained herein shall prohibit or in any way limit the INMETCO Agent or any INMETCO Facility Lender from objecting in any Insolvency or Liquidation Proceeding or otherwise
to any action taken by the Collateral Agent, the Trustee or any of the other Indenture Holders with respect to the INMETCO Collateral, including objecting to the seeking by the Collateral Agent, the Trustee or any other Indenture Holder of adequate
protection (other than as allowed pursuant to Section 6.3(a) above) or the asserting by the Collateral Agent, the Trustee or any other Indenture Holder of any of its rights and remedies under the Indenture Documents or otherwise in respect of
the INMETCO Collateral. 
 6.5 Preference Issues. If any INMETCO Facility Lender is required in any Insolvency or
Liquidation Proceeding or otherwise to turn over or otherwise pay to the estate of any Grantor any amount (a “INMETCO Facility Claim Recovery”), then the INMETCO Facility Claims shall be reinstated to the extent of such INMETCO Facility
Claim Recovery and the INMETCO Facility Lenders shall be entitled to receive payment in full in cash (including, in the case of any letter of credit, cash collateral therefor) with respect to all such recovered amounts. If this Agreement shall have
been terminated prior to such INMETCO Facility Claim Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties
hereto. The Collateral Agent, the Trustee and each other Indenture Holder agree 

  
 G-17

 
that none of them shall be entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation made in accordance with this Agreement, whether by
preference or otherwise; it being understood and agreed that the benefit of such avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement.

 6.6 Asset Dispositions in an Insolvency or Liquidation Proceeding. None of the Collateral Agent, the Trustee, or any
other Indenture Holder shall, in an Insolvency or Liquidation Proceeding or otherwise, oppose any sale or disposition of any INMETCO Collateral that is supported by the INMETCO Facility Lenders, and the Collateral Agent, the Trustee and each other
Indenture Holder will be deemed to have consented under Section 363 of Title 11 of the United States Code (and otherwise) to any such sale supported by the requisite INMETCO Facility Lenders (as determined in accordance with the Credit
Agreement) and to have released their Liens in such assets. 
 6.7 Separate Grants of Security and Separate
Classification. 
 The Indenture Holders and the INMETCO Facility Lenders acknowledge and agree that: (a) the grants of
Liens pursuant to the INMETCO Facility Collateral Documents and the Indenture Collateral Documents constitute two separate and distinct grants of Liens; and (b) because of, among other things, their differing rights in the INMETCO Collateral,
the Indenture Obligations are fundamentally different from the INMETCO Facility Claims and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency or Liquidation Proceeding. To further effectuate the intent
of the parties as provided in the immediately preceding sentence, if it is held that the claims against the INMETCO Facility Lenders and Indenture Holders in respect of the INMETCO Collateral constitute only one secured claim (rather than separate
classes of senior and junior secured claims), then, the Indenture Holders hereby acknowledge and agree that all distributions shall be made as if there were separate classes of senior and junior secured claims against the Grantors in respect of the
INMETCO Collateral (with the effect being that, to the extent that the aggregate value of the INMETCO Collateral is sufficient (for this purpose ignoring all claims held by the Indenture Holders), the INMETCO Facility Lenders shall be entitled to
receive from the INMETCO Collateral or proceeds thereof, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of all interest accrued (or which would have, absent
the commencement of an Insolvency or Liquidation Proceeding, accrued) after the commencement of an Insolvency or Liquidation Proceeding before any distribution is made from the INMETCO Collateral or proceeds thereof in respect of the claims held by
the Indenture Holders), with the Indenture Holders hereby acknowledging and agreeing to turn over to the INMETCO Facility Lenders amounts otherwise received or receivable by them from the INMETCO Collateral or proceeds thereof to the extent
necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Indenture Holders. 
 6.8 Certain Waivers as to Section 1111(b)(2) of Bankruptcy Law. 
 The
Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, waives any claim they may hereafter have against any INMETCO Facility Lender arising out of the election by INMETCO Agent or any other INMETCO Facility Lender of the
application of Section 1111(b)(2) of the Bankruptcy Law, or any comparable provision of any similar law. The INMETCO Agent, on behalf of itself and the other INMETCO Facility Lenders, waives any claim they may hereafter have against any
Indenture Holder arising out of the election by Collateral Agent, Trustee or any other Indenture Holder of the application of Section 1111(b)(2) of the Bankruptcy Law, or any comparable provision of any similar law. 

6.9 Effectiveness in Insolvency or Liquidation Proceedings. 

  
 G-18

 This Agreement shall be effective both before and after the commencement of an Insolvency or
Liquidation Proceeding involving any Grantor, including, without limitation, the filing of any petition by or against any Grantor under any Bankruptcy Law and all converted or subsequent cases in respect thereof, and all references herein to any
Grantor shall be deemed to apply to the trustee for such Grantor and such Grantor as debtor-in-possession. The relative rights of the INMETCO Facility Lenders and the Indenture Holders in or to any distributions from or in respect of any INMETCO
Collateral or proceeds thereof shall continue after the institution of any Insolvency or Liquidation Proceeding involving any Grantor, including, without limitation, the filing of any petition by or against any Grantor under the Bankruptcy Law and
all converted cases and subsequent cases, on the same basis as prior to the date of such institution, subject to any court order approving the financing of, or use of cash collateral by, any Grantor as debtor-in-possession, or any other court order
affecting the rights and interests of the parties hereto not in conflict with this Agreement. This Agreement shall constitute a subordination agreement for the purposes of Section 510(a) of the Bankruptcy Code and shall be enforceable in any
Insolvency or Liquidation Proceeding in accordance with its terms. 
 SECTION 7. Reliance; Waivers; Etc. 

7.1 Reliance. 
 All loans and other extensions of credit made or deemed made on and after the date hereof by the INMETCO Facility Lenders to the Company or any other Grantor shall be deemed to have been given and made in
reliance upon this Agreement. All extensions of credit or other financial accommodations made or deemed made on and after the date hereof by the Indenture Holders to the Issuer or any other Grantor shall be deemed to have been given and made in
reliance upon this Agreement. 
 7.2 No Warranties or Liability. 

The Collateral Agent, on behalf of itself, the Trustee and the other Indenture Holders, acknowledges and agrees that each of the INMETCO
Agent and the INMETCO Facility Lenders have made no express or implied representation or warranty, including with respect to the execution, validity, legality, completeness, collectibility or enforceability of any of the INMETCO Facility Documents,
the ownership of any INMETCO Collateral or the perfection or priority of any Liens thereon. 
 The INMETCO Agent, on behalf of
itself and the INMETCO Facility Lenders, acknowledges and agrees that each of the Collateral Agent, the Trustee and the other Indenture Holders have made no express or implied representation or warranty, including with respect to the execution,
validity, legality, completeness, collectibility or enforceability of any of the Indenture Documents, the ownership of any INMETCO Collateral or the perfection or priority of any Liens thereon. 

The INMETCO Facility Lenders will be entitled to manage and supervise their respective loans and extensions of credit under the INMETCO
Facility Documents as they may, in their sole discretion, deem appropriate, and the INMETCO Facility Lenders may manage their loans and extensions of credit without regard to any rights or interests that the Collateral Agent, the Trustee or any of
the other Indenture Holders have in the INMETCO Collateral or otherwise, except as otherwise provided in this Agreement. Neither the INMETCO Agent nor any INMETCO Facility Lender shall have any duty to the Collateral Agent, the Trustee or any of the
other Indenture Holders to act or refrain from acting in a manner which allows, or results in, the occurrence or continuance of an event of default or default under any agreements with the Issuer or any other Grantor (including the Indenture
Documents), regardless of any knowledge thereof which they may have or be charged with. 

  
 G-19

 The Indenture Holders will be entitled to manage and supervise their respective loans and
extensions of credit under the Indenture Documents as they may, in their sole discretion, deem appropriate. Neither the Collateral Agent, the Trustee nor any other Indenture Holder shall have any duty to the INMETCO Agent or any of the INMETCO
Facility Lenders to act or refrain from acting in a manner which allows, or results in, the occurrence or continuance of an event of default or default under any agreements with the Issuer or any other Grantor (including the INMETCO Facility
Documents), regardless of any knowledge thereof which they may have or be charged with. 
 7.3 No Waiver of Lien
Priorities. 
 (i) No right of the INMETCO Facility Lenders, the INMETCO Agent or any of them to enforce any provision of
this Agreement or any INMETCO Facility Document shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or any other Grantor or by any act or failure to act by any INMETCO Facility Lender or the
INMETCO Agent, or by any noncompliance by any Person with the terms, provisions and covenants of this Agreement, any of the INMETCO Facility Documents or any of the Indenture Documents, regardless of any knowledge thereof which the INMETCO Agent or
the INMETCO Facility Lenders, or any of them, may have or be otherwise charged with; 
 (ii) Without in any way limiting the
generality of the foregoing paragraph but subject to Section 2.4, the INMETCO Facility Lenders, the INMETCO Agent and any of them, may, at any time and from time to time, without the consent of, or notice to, the Collateral Agent, the
Trustee or any other Indenture Holder, without incurring any liabilities to the Collateral Agent, the Trustee or any other Indenture Holder and without impairing or releasing the Lien priorities and other benefits provided in this Agreement (even if
any right of subrogation or other right or remedy of the Collateral Agent, the Trustee or any other Indenture Holder is affected, impaired or extinguished thereby) do any one or more of the following: 

(A) change the manner, place or terms of payment or change or extend the time of payment of, or amend, renew, exchange, increase or
alter, the terms of any of the INMETCO Facility Claims or any Lien on any INMETCO Collateral or guaranty thereof or any liability of the Issuer or any other Grantor, or any liability incurred directly or indirectly in respect thereof (including any
increase in or extension of the INMETCO Facility Claims, without any restriction as to the amount, tenor or terms of any such increase or extension so long as the maximum aggregate principal amount of INMETCO Facility Claims described in clause
(a) of the definition thereof does not exceed the Maximum Credit Facility Principal Amount) or otherwise amend, renew, exchange, extend, modify or supplement in any manner any Liens held by the INMETCO Agent or any of the INMETCO Facility

 SECTION 8. Miscellaneous. 

8.1 Conflicts. 
 In the event of any conflict between the provisions of this Agreement and the provisions of the INMETCO Facility Documents or the Indenture Documents, the provisions of this Agreement shall govern;

provisions of this Agreement by the Collateral Agent or the INMETCO Agent shall be deemed to be made unless the same shall be in writing signed on behalf of each party hereto or its authorized agent. Each waiver, if any, shall be in writing, signed
by the party granting the waiver, and shall be a waiver only with respect to the specific instance involved and shall in no way impair the rights of the parties making such waiver or the obligations of the other parties to such party in any other
respect or at any other time. The Issuer and other Grantors shall not have any right to consent to or approve any amendment, modification or waiver of any provision of this Agreement.

Holders’ portion of the Indenture Obligations outstanding on the date of purchase held by all such Indenture Holders, or as otherwise agreed by such Indenture Holders). When all such letters of credit have been cancelled with the consent of the

Agreement. If the right set forth in this Section 8.15 is exercised: (1) the parties shall endeavor to close promptly thereafter but in any event within ten (10) Business Days of the notice thereof, (2) such purchase of
the Indebtedness under the Credit Agreement shall be exercised pursuant to documentation mutually and reasonably acceptable to each of the INMETCO Agent and the Collateral Agent, and (3) such Indebtedness under the Credit Agreement shall be
purchased pro rata among the Indenture Holders giving notice to the Collateral Agent of their intent to exercise the purchase option hereunder according to such Indenture Holders’ portion of the Indenture Obligations outstanding on the date of
purchase (or as otherwise agreed by such Indenture Holders giving notice) pursuant to this Section 8.15. In the event that any one or more of the Indenture Holders exercises the purchase option set forth in this Section 8.15:
(A) the INMETCO Agent shall have the right, but not the obligation, to immediately resign under the INMETCO Facility Documents upon the closing of such purchase, (B) the purchasing Indenture Holders shall have the right, but not the
obligation, to require the INMETCO Agent to immediately resign under the INMETCO Facility Documents upon the closing of such purchase, and (C) the INMETCO Agent shall take such action with respect to the INMETCO Collateral in an Insolvency or
Liquidation Proceeding as may be reasonably requested in good faith and in writing by the Collateral Agent (at the direction and on behalf of the purchasing Indenture Holders) until the closing of such purchase (but in no event later than ten
(10) Business Days after the delivery of notice thereof); provided, however, (I) if the INMETCO Agent so requests, it shall first be indemnified to its reasonable satisfaction from the purchasing Indenture Holders against any
and all liability, loss and expense that may be incurred by it by reason of taking or continuing to take, or refraining from taking, any such action, (II) the INMETCO Agent shall not be required to take any action that, in the determination of the
INMETCO Agent in its sole discretion, is not permitted under the INMETCO Facility Documents or applicable law or will result in liability to the INMETCO Agent or any of the INMETCO Facility Lenders, (III) unless and until the INMETCO Agent has
received any such written request and indemnification, the INMETCO Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Insolvency or Liquidation Proceeding as it shall deem advisable
or as the INMETCO Facility Lenders shall so direct, and (IV) the INMETCO Agent shall have the right, but not the obligation, to appoint any purchasing Indenture Holder, as its agent for the purposes of taking any action requested by the Collateral
Agent pursuant to this clause (C).

any of the rights and remedies of the Collateral Agent and the Holders hereunder or thereunder. All present and future laws, statutes, codes, ordinances, orders, judgments, decrees, rules, regulations and requirements of every Governmental Authority
applicable to Mortgagor or to any of the Mortgaged Property and all covenants, restrictions, and conditions which now or later may be applicable to any of the Mortgaged Property are collectively referred to as the “Legal
Requirements.” 

  
 H-4

	 	(b)	From and after the date of this Mortgage, Mortgagor shall not by act or omission permit any building or other improvement on any premises not subject to the lien
created by this Mortgage to rely on the Premises or any part thereof or any interest therein to fulfill any Legal Requirement, and Mortgagor hereby assigns to Mortgagee any and all rights to give consent for all or any portion of the Premises or any
interest therein to be so used. Mortgagor shall not by act or omission impair the integrity of any of the Real Estate as a single zoning lot separate and apart from all other premises. Mortgagor represents that each parcel of the Real Estate
constitutes a legally subdivided lot, in compliance with all subdivision laws and similar Legal Requirements. Any act or omission by Mortgagor which would result in a violation of any of the provisions of this subsection shall be void.

 4. Payment of Taxes and Other Impositions. 

 

	 	(a)	Promptly when due, Mortgagor shall pay and discharge all taxes, assessments and governmental charges imposed upon or assessed against or which may become a lien on any
of the Mortgaged Property, or arising in respect of the occupancy, use or possession thereof (all of the foregoing are collectively referred to as the “Impositions”) in accordance with Section 4.04 of the Indenture. If by law
any Imposition, at Mortgagor’s option, may be paid in installments (whether or not interest shall accrue on the unpaid balance of such Imposition), Mortgagor may elect to pay such Imposition in such installments and shall be responsible for the
payment of such installments with interest, if any. 

  

	 	(b)	If Mortgagor is in default of its obligation to pay and discharge Impositions as required under this Section 5, then Mortgagee, at its option, may pay any
Imposition after the date such Imposition shall have become due. Any sums paid by Mortgagee in discharge of any Impositions shall be payable on demand by Mortgagor to Mortgagee together with interest at the Default Rate as set forth above.

  

	 	(c)	Mortgagor shall not claim, demand or be entitled to receive any credit or credits toward the satisfaction of this Mortgage or on any interest payable thereon for any
taxes assessed against the Mortgaged Property or any part thereof, and shall not claim, to the extent any such claim could materially affect the lien of this Mortgage, any deduction from the taxable value of the Mortgaged Property by reason of this
Mortgage. 

 5. Insurance. 
  

	 	(a)	 Mortgagor shall maintain insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of
Mortgagor, are adequate and appropriate for the conduct of the business of Mortgagor in a prudent manner, with reputable insurers or with the government of the United 

  
 H-5

	 	
States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the good faith judgment of Mortgagor, for companies similarly
situated in the industry in which Mortgagor is engaged. 

  

	 	(b)	If any portion of the Premises is located in a federally designated special flood hazard area, the Mortgagor shall keep the improvements on the Premises insured against
loss by flood in an amount at least equal to the outstanding Obligations or the maximum limit of coverage available with respect to such improvements under the applicable federal statute, whichever is less. 

 

	 	(c)	Mortgagor will cause any property and casualty insurance policies with respect to the Mortgaged Property to be endorsed or otherwise amended to include a
“standard” or “New York” lender’s loss payable endorsement, which endorsement or policy shall provide that if the insurance carrier shall have received written notice from Mortgagee of the occurrence of an Event of Default,
the insurance carrier shall pay all proceeds otherwise payable to Mortgagor under such policies directly to the Trustee. Mortgagor shall cause all such policies to provide that neither Mortgagor, Mortgagee nor any other party shall be a coinsurer
thereunder and to contain a “Replacement Cost Endorsement” or similar endorsement without any deduction for depreciation. Liability insurance policies shall name Mortgagee as an additional insured and contain a waiver of subrogation
against Mortgagee. 

  

	 	(d)	If Mortgagor is in default of its obligations to insure as required under this Section 5, then Mortgagee, at its option, may effect such insurance from year to
year, and pay the premium or premiums therefor, and Mortgagor shall pay to Mortgagee on demand such premium or premiums so paid by Mortgagee with interest from the time of payment at the Default Rate. 

 

	 	(e)	In the event of foreclosure of this Mortgage or other transfer of title to the Mortgaged Property, all right, title and interest of Mortgagor in and to any insurance
policies then in force shall pass to the purchaser or grantee. 

 6. Restrictions on Liens and Encumbrances.
Except for the lien of this Mortgage and the Permitted Liens, and except as expressly permitted under the Indenture, Mortgagor shall not further mortgage, nor otherwise encumber the Mortgaged Property nor create or suffer to exist any lien, charge
or encumbrance on the Mortgaged Property, or any part thereof, whether superior or subordinate to the lien created by this Mortgage and whether recourse or non-recourse. 
 7. Due on Sale and Other Transfer Restrictions. Except as expressly permitted under the Indenture, Mortgagor shall not sell, transfer, convey or assign all or any portion of, or any interest in,
the Mortgaged Property. 

  
 H-6

 8. Maintenance; No Alteration; Inspection; Utilities. 

(a) Mortgagor shall maintain or cause to be maintained all the Improvements in good condition and repair and shall not commit or suffer
any waste of the Improvements. Mortgagor shall repair, restore, replace or rebuild promptly any part of the Premises which may be damaged or destroyed by casualty. The Improvements shall not be demolished (without replacing) or altered, nor any
additions built, which in any of the foregoing events would materially reduce the fair market value of the Mortgaged Property. 

(b) Mortgagee and any persons authorized by Mortgagee shall have the right upon reasonable notice to enter and inspect the Premises and
all work done, labor performed and materials furnished in and about the Improvements. 
 (c) Mortgagor shall pay or cause to be
paid when due all utility charges which are incurred for gas, electricity, water or sewer services furnished to the Premises and all other assessments or charges of a similar nature, whether public or private, affecting the Premises or any portion
thereof, whether or not such assessments or charges are liens thereon. 
 9. Condemnation/Eminent Domain. Promptly upon
obtaining knowledge of the institution of any proceedings for the condemnation of the Mortgaged Property, or any portion thereof, Mortgagor will notify Mortgagee of the pendency of such proceedings. Mortgagee is hereby authorized and empowered by
Mortgagor to settle or compromise any claim in connection with such condemnation and to receive all awards and proceeds thereof to be held by Mortgagee as collateral to secure the payment and performance of the Obligations. Notwithstanding the
preceding sentence, provided no Event of Default shall have occurred and be continuing, Mortgagor shall, at its expense, diligently prosecute any proceeding relating to such condemnation, settle or compromise any claims in connection therewith and
receive any awards or proceeds thereof, provided that Mortgagor shall promptly repair and restore the Mortgaged Property to its condition prior to such condemnation, regardless of whether any award shall have been received or whether such award is
sufficient to pay for the costs of such repair and restoration. 
 10. Restoration. Mortgagor shall use all insurance
proceeds and all condemnation proceeds and awards to restore the Mortgaged Property promptly to its condition prior to such casualty or condemnation (giving effect to the remaining configuration of the Premises after such condemnation), and in
compliance with all Legal Requirements. 
 11. Further Assurances. To further assure Mortgagee’s rights under this
Mortgage, Mortgagor agrees upon demand of Mortgagee to do any act or execute any additional documents (including, but not limited to, security agreements on any personalty included or to be included in the Mortgaged Property and a separate
assignment of each Lease in recordable form) as may be required by Mortgagee to confirm the lien of this Mortgage and all other rights or benefits conferred on Mortgagee. 

  
 H-7

 12. Mortgagee’s Right to Perform. Upon the occurrence and during the
continuation of an Event of Default, Mortgagee may, at any time, but shall be under no obligation to, pay or perform any of the covenants or agreements of Mortgagor, without waiving or releasing Mortgagor from any obligation or default under this
Mortgage, and the amount or cost thereof, with interest at the Default Rate, shall immediately be due from Mortgagor to Mortgagee and the same shall be secured by this Mortgage and shall be an encumbrance on the Mortgaged Property prior to any
right, title to, interest in or claim upon the Mortgaged Property attaching subsequent to the date of this Mortgage. No payment or advance of money by Mortgagee under this Section shall be deemed or construed to cure Mortgagor’s default or
waive any right or remedy of Mortgagee. 
 13. Secured Amount. The maximum aggregate amount of all
indebtedness that is, or under any contingency may be secured at the date hereof or at any time hereafter by this Mortgage is $[            ]2 (the “Secured Amount”), plus, to the extent
permitted by applicable law, collection costs, sums advanced for the payment of taxes, assessments, maintenance and repair charges, insurance premiums and any other costs incurred to protect the security encumbered hereby or the lien hereof,
expenses incurred by the Mortgagee by reason of any default by the Mortgagor under the terms hereof, together with interest thereon, all of which amount shall be secured hereby. So long as the aggregate amount of the Obligations exceeds the Secured
Amount, any payments and repayments of the Obligations shall not be deemed to be applied against or to reduce the Secured Amount. 
 14. Events of Default. The occurrence of an Event of Default under the Indenture shall constitute an Event of Default hereunder. 

15. Remedies. 
 (a) Upon the occurrence and during the continuation of an Event of Default, in addition to any other rights and remedies Mortgagee may have pursuant to the Indenture or any of the Collateral Agreements,
or as provided by law, and without limitation, Mortgagee may immediately take such action, without notice or demand, as it deems advisable to protect and enforce its rights against Mortgagor and in and to the Mortgaged Property, including, but not
limited to, the following actions, each of which may be pursued concurrently or otherwise, at such time and in such manner as Mortgagee may determine, in its sole discretion, without impairing or otherwise affecting the other rights and remedies of
Mortgagee: 
 (i) Mortgagee may elect to cause the Mortgaged Property or any part thereof to be sold as follows: 

(A) Mortgagee may proceed as if all of the Mortgaged Property were real property in accordance with subparagraph (C) below, or
Mortgagee may elect to treat any of the Mortgaged Property which consists of a right in action or which is property that can be severed from the Real Estate without causing structural damage thereto as if the same were personal property, and dispose
of the same in accordance with the provisions of this Mortgage which relate to the exercise of remedies with respect to that portion of the Mortgaged Property which is personal property, separate and apart from the sale of real property. 

 
  

	2 	 Insert $192,500,000; provided that if the Land subject to this Mortgage is located in a jurisdiction where a mortgage tax with respect to this
Mortgage is calculated based on the amount secured hereby, insert an amount equal to 110% of the fair market value of such Land. 

  
 H-8

 (B) Mortgagee may cause any such sale or other disposition to be conducted immediately
following the expiration of any grace period, if any, herein provided, and any advertisement, the giving of any notices and the expiration of any time period required by law or herein, or Mortgagee may delay any such sale or other disposition for
such period of time as Mortgagee deems to be appropriate. Should Mortgagee desire that more than one (1) such sale or other disposition be conducted, Mortgagee may, at its option, cause the same to be conducted simultaneously, or successively,
on the same day, or at such different days or times and in such order as Mortgagee may deem to be appropriate. 
 (C) Should
Mortgagee elect to sell the Mortgaged Property or any part thereof which is real property or which Mortgagee has elected to treat as real property, upon such election, the Mortgagee shall give such notice of default and election to sell as may then
be required by law. Thereafter, upon the expiration of such time and the giving of the required notice(s) and after having advertised the sale as required by law, and without the necessity of any demand on Mortgagor except as required herein or by
law, Mortgagee, at the time and place specified in the notice of sale, shall sell the Mortgaged Property or any portion thereof specified by Mortgagee, at public auction to the highest bidder for cash in lawful money of the United States. Mortgagee
may, from time to time, postpone the sale by public announcement thereof at the time and place noticed therefor. If the Mortgaged Property consists of several lots or parcels, Mortgagee may designate the order in which such lots or parcels shall be
offered for sale or sold. Any person, including Mortgagor or Mortgagee, may purchase at the sale. Upon any sale, Mortgagee shall execute and deliver to the purchaser or purchasers a deed or deeds conveying the property so sold, but without any
covenant or warranty whatsoever, express or implied, whereupon such purchaser or purchasers shall be entitled to immediate possession. 
 (D) In the event of a sale or other disposition of the Mortgaged Property, or any part thereof, and the execution of a deed or other conveyance pursuant thereto, the recitals therein of facts, such as
default, the giving of notice of default and notice of sale, demand that such sale should be made, postponement of sale, terms of sale, sale, purchase, payment of purchase money and other facts affecting the regularity or validity of such sale or
disposition, shall be conclusive proof of the truth of such facts; any such deed or conveyance shall be conclusive against all persons as to such facts recited therein. 
 (E) The acknowledgment of the receipt of the purchase money, contained in any deed or conveyance executed as aforesaid, shall be sufficient discharge to the grantee from all obligations to see to the
proper application of the consideration therefor as hereinafter provided. 
 (ii) Mortgagee may, to the extent permitted by
applicable law, (A) institute and maintain an action of judicial foreclosure against all or any part of the Mortgaged Property, (B) institute and maintain an action on the Note, (C) sell all or part of the Mortgaged Property
(Mortgagor expressly granting to Mortgagee the power of sale) as set forth above or (D) take such other action at law or in equity for the enforcement of this Mortgage, the 

  
 H-9

 
Indenture or any of the other Collateral Agreements as the law may allow. Mortgagee may proceed in any such action to final judgment and execution thereon for all sums due hereunder, together
with interest thereon at the Default Rate and all costs of suit, including, without limitation, reasonable attorneys’ fees and disbursements. Interest at the Default Rate shall be due on any judgment obtained by Mortgagee from the date of
judgment until actual payment is made of the full amount of the judgment. 
 (iii) Mortgagee may, to the extent permitted by
applicable law, personally, or by its agents, attorneys and employees and without regard to the adequacy or inadequacy of the Mortgaged Property or any other collateral as security for the Obligations enter into and upon the Mortgaged Property and
each and every part thereof and exclude Mortgagor and its agents and employees therefrom without liability for trespass, damage or otherwise (Mortgagor hereby agreeing to surrender possession of the Mortgaged Property to Mortgagee upon demand at any
such time) and use, operate, manage, maintain and control the Mortgaged Property and every part thereof. Following such entry and taking of possession, Mortgagee shall be entitled, without limitation, (A) to lease all or any part or parts of
the Mortgaged Property for such periods of time and upon such conditions as Mortgagee may, in its discretion, deem proper, (B) to enforce, cancel or modify any Lease and (C) generally to execute, do and perform any other act, deed, matter
or thing concerning the Mortgaged Property as Mortgagee shall deem appropriate as fully as Mortgagor might do. 
 (iv) Upon the
completion of any sale or sales made by Mortgagee, as the case may be, under or by virtue of this subsection (a), Mortgagee or any officer of any court empowered to do so, shall execute and deliver as aforesaid, to the accepted purchaser or
purchasers a good and sufficient instrument, or good and sufficient instruments, conveying, assigning and transferring all estate, right, title and interest in and to the property and rights sold. Mortgagee is hereby appointed irrevocably the true
and lawful attorney of Mortgagor in its name and stead to make all necessary conveyances, assignments, transfers and deliveries of the Mortgaged Property or any part thereof and the rights so sold and for that purpose, Mortgagee may execute all
necessary instruments of conveyance, assignment and transfer, and may substitute one or more persons with like power, Mortgagor hereby ratifying and confirming all that its attorney or any substitute or substitutes shall lawfully do by virtue
hereof. Nevertheless, Mortgagor, if so requested by Mortgagee, shall ratify and confirm any such sale or sales by executing and delivering to Mortgagee or to such purchaser or purchasers all such instruments as may be advisable, in the judgment of
Mortgagee, for the purpose as may be designated in such request. 
 (v) Mortgagor hereby expressly waives any right which it may
have to direct the order in which any of the Mortgaged Property shall be sold in the event of any sale or sales pursuant hereto. 
 (b) Mortgagee, in any action to foreclose this Mortgage in a judicial procedure or in connection with the exercise of any power of sale, shall be entitled to the appointment of a receiver. In case of a
trustee’s sale or foreclosure sale, the Real Estate may be sold, at Mortgagee’s election, in one parcel or in more than one parcel and Mortgagee is specifically empowered (without being required to do so, and in its sole and absolute
discretion) to cause successive sales of portions of the Mortgaged Property to be held. 

  
 H-10

 (c) In the event of any breach of any of the covenants, agreements, terms or conditions
contained in this Mortgage, Mortgagee shall be entitled to enjoin such breach and obtain specific performance of any covenant, agreement, term or condition and Mortgagee shall have the right to invoke any equitable right or remedy as though other
remedies were not provided for in this Mortgage. 
 16. Right of Mortgagee to Credit Sale. Upon the occurrence of any sale
made under this Mortgage, whether made under the power of sale or by virtue of judicial proceedings or of a judgment or decree of foreclosure and sale, Mortgagee may bid for and acquire the Mortgaged Property or any part thereof. In lieu of paying
cash therefor, Mortgagee may make settlement for the purchase price by crediting upon the Obligations or other sums secured by this Mortgage the net sales price after deducting therefrom the expenses of sale and the cost of the action and any other
sums that Mortgagee is authorized to deduct under this Mortgage. In such event, this Mortgage, the Indenture, and documents evidencing the Obligations and the other expenditures secured hereby may be presented to the person or persons conducting the
sale in order that the amount so used or applied may be credited upon the Obligations as having been paid. 
 17. Appointment
of Receiver. If an Event of Default shall have occurred and be continuing, Mortgagee as a matter of right and without notice to Mortgagor, unless otherwise required by applicable law, and without regard to the adequacy or inadequacy of the
Mortgaged Property or any other collateral as security for the Obligations or the interest of Mortgagor therein, shall have the right to apply to any court having jurisdiction to appoint a receiver or receivers or other manager of the Mortgaged
Property, and Mortgagor hereby irrevocably consents to such appointment and waives notice of any application therefor (except as may be required by law). Any such receiver or receivers shall have all the usual powers and duties of receivers in like
or similar cases and all the powers and duties of Mortgagee in case of entry as provided in this Mortgage, including, without limitation and to the extent permitted by law, the right to enter into leases of all or any part of the Mortgaged Property
and exercise all such powers until the date of confirmation of sale of the Mortgaged Property unless such receivership is sooner terminated. 
 18. Extension, Release, etc. 
 (a) Without affecting the lien or charge of
this Mortgage upon any portion of the Mortgaged Property not then or theretofore released as security for the full amount of the Obligations, Mortgagee may, from time to time and without notice, agree to (i) release any person liable for any
portion of the Obligations, (ii) extend the maturity or alter any of the terms of the indebtedness guaranteed under any guaranty of any of the Obligations, (iii) grant other indulgences, (iv) release or reconvey, or cause to be
released or reconveyed at any time at Mortgagee’s option any parcel, portion or all of the Mortgaged Property, (v) take or release any other or additional security for any Obligation herein mentioned, or (vi) make compositions or
other arrangements with debtors in relation thereto. If at any time this Mortgage shall secure less than all of the principal amount of the Obligations, it is expressly agreed that any repayments of the principal amount of the Obligations shall not
reduce the amount of the encumbrance created by this Mortgage until the encumbrance amount shall equal the principal amount of the Obligations outstanding. 

  
 H-11

 (b) No recovery of any judgment by Mortgagee and no levy of an execution under any judgment
upon the Mortgaged Property or upon any other property of Mortgagor shall affect the encumbrance of this Mortgage or any liens, rights, powers or remedies of Mortgagee hereunder, and such liens, rights, powers and remedies shall continue unimpaired.

 (c) If Mortgagee shall have the right to foreclose this Mortgage, Mortgagor authorizes Mortgagee at its option to foreclose
the lien of this Mortgage subject to the rights of any tenants of the Mortgaged Property. The failure to make any such tenants parties defendant to any such foreclosure proceeding and to foreclose their rights will not be asserted by Mortgagor as a
defense to any proceeding instituted by Mortgagee to collect the Obligations or to foreclose the lien of this Mortgage. 
 (d)
Unless expressly provided otherwise, in the event that ownership of this Mortgage and title to the Mortgaged Property or any estate therein shall become vested in the same person or entity, this Mortgage shall not merge in such title but shall
continue as a valid lien on the Mortgaged Property for the amount secured hereby. 
 19. Fixture Filing. To the extent any
of the Mortgaged Property constitutes “fixtures” within the meaning of the Uniform Commercial Code (the “Code”) of the state where the Real Estate is located, then this Mortgage is to be filed and effective as a
financing statement filed as a fixture filing within the meaning of the Code. The Mortgagor is the “Debtor,” and the address of the Debtor set forth in the initial paragraph of this Mortgage is the mailing address of the Debtor. The
Mortgagee is the “Secured Party” and the place of business of the Mortgagee set forth in the initial paragraph of this Mortgage is an address of the Secured Party from which information concerning the security interest may be
obtained. 
 20. Assignment of Rents. Mortgagor hereby assigns to Mortgagee the Rents as further security for the payment
and performance of all of the Obligations, and Mortgagor grants to Mortgagee the right to enter the Mortgaged Property for the purpose of collecting the same and to let the Mortgaged Property or any part thereof, and to apply the Rents on account of
the Obligations. The foregoing assignment and grant is present and absolute and shall continue in effect until the Obligations are paid and performed in full, but Mortgagee hereby waives the right to enter the Mortgaged Property for the purpose of
collecting the Rents, and Mortgagor shall be entitled to collect, receive, use and retain the Rents unless an Event of Default shall be in effect; such right of Mortgagor to collect, receive, use and retain the Rents may be revoked by Mortgagee if
an Event of Default occurs by giving not less than five days’ written notice of such revocation to Mortgagor, in the event such notice is given, Mortgagor shall pay over to Mortgagee, or to any receiver appointed to collect the Rents, the Rents
and any lease security deposits. Mortgagor shall not accept prepayments of installments of Rent to become due for a period of more than one month in advance (except for security deposits and estimated payments of percentage rent, if any).

 21. Trust Funds. To the extent required under applicable law, all lease security deposits of the Real Estate shall be
treated as trust funds not to be commingled with any other funds of Mortgagor. Within 10 days after request by Mortgagee, Mortgagor shall furnish Mortgagee satisfactory evidence of compliance with this section, together with a statement of all lease
security deposits by lessees and copies of all Leases not previously delivered to Mortgagee, which statement shall be certified by Mortgagor. 

  
 H-12

 22. Additional Rights. The holder of any subordinate lien or subordinated mortgage on
the Mortgaged Property shall have no right to terminate any Lease whether or not such Lease is subordinate to this Mortgage, nor shall Mortgagor consent to any holder of any subordinate lien joining any tenant under any Lease in any action to
foreclose such lien or modify, interfere with, disturb or terminate the rights of any tenant under any Lease. By recordation of this Mortgage all subordinate lienholders and the beneficiaries under subordinate mortgages are subject to and notified
of this provision, and any action taken by any such lienholder or beneficiary contrary to this provision shall be null and void. If an Event of Default occurs and is continuing, Mortgagee may, in its sole discretion and without regard to the
adequacy of its security under this Mortgage, apply all or any part of any amounts on deposit with Mortgagee under this Mortgage against the Obligations as more fully set forth in the Indenture. Any such application shall not be construed to cure or
waive any Default or Event of Default or invalidate any act taken by Mortgagee on account of such Default or Event of Default. 

23. Notices. All notices or other communications hereunder shall be given in the manner and to the addresses determined under the
Indenture. 
 24. No Oral Modification. This Mortgage may not be changed or terminated orally. Any agreement made by
Mortgagor and Mortgagee after the date of this Mortgage relating to this Mortgage shall be superior to the rights of the holder of any intervening or subordinate lien or encumbrance. 

25. Partial Invalidity. In the event any one or more of the provisions contained in this Mortgage shall for any reason be held to
be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof, but each shall be construed as if such invalid, illegal or unenforceable provision had never been
included. Notwithstanding anything to the contrary contained in this Mortgage, the Indenture or any of the other Collateral Agreements, the obligations of Mortgagor and of any other obligor under the Indenture and the Collateral Agreements shall be
subject to the limitation that Mortgagee shall charge, take or receive, and neither Mortgagor nor any other obligor shall be obligated to pay to Mortgagee, any amounts constituting interest in excess of the maximum rate permitted by law to be
charged by Mortgagee. 
 26. Mortgagor’s Waiver of Rights. To the fullest extent permitted by law, Mortgagor waives
the benefit of all laws now existing or that may subsequently be enacted providing for (i) any appraisement before sale of any portion of the Mortgaged Property, (ii) any extension of the time for the enforcement of the collection of the
Obligations or the creation or extension of a period of redemption from any sale made in collecting such debt and (iii) exemption of the Mortgaged Property from attachment, levy or sale under execution or exemption from civil process. To the
full extent Mortgagor may do so, Mortgagor agrees that Mortgagor will not at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any appraisement, valuation, stay of execution,
exemption, extension or redemption, or requiring foreclosure of this Mortgage before exercising any other remedy granted hereunder and Mortgagor, for Mortgagor and its successors and 

  
 H-13

 
assigns, and for any and all persons ever claiming any interest in the Mortgaged Property, to the extent permitted by law, hereby waives and releases all rights of redemption, valuation,
appraisement, stay of execution, notice of election to mature or declare due the whole of the secured indebtedness and marshalling in the event of exercise by Mortgagee of the power of sale or other rights hereby created. Mortgagor further waives,
to the extent permitted by applicable law, all errors and imperfections in any proceedings instituted by Mortgagee under this Mortgage, and all notices of any Event of Default (except as may be provided for under this Mortgage) or of
Mortgagee’s election to exercise its actual exercise of any right, remedy or recourse provided for under this Mortgage. 

27. Remedies Not Exclusive. Mortgagee shall be entitled to enforce payment and performance of all of the Obligations and to
exercise all rights and powers under this Mortgage, or under any of the Collateral Agreements, or other agreement or any laws now or hereafter in force, notwithstanding some or all of the Obligations may now or hereafter be otherwise secured,
whether by mortgage, security agreement, pledge, lien, assignment or otherwise. Neither the acceptance of this Mortgage nor its enforcement, shall prejudice or in any manner affect Mortgagee’s right to realize upon or enforce any other security
now or hereafter held by Mortgagee, it being agreed that Mortgagee shall be entitled to enforce this Mortgage and any other security now or hereafter held by Mortgagee in such order and manner as Mortgagee may determine in its absolute discretion.
No remedy herein conferred upon or reserved to Mortgagee is intended to be exclusive of any other remedy herein or by law provided or permitted, but each shall be cumulative and shall be in addition to every other remedy given hereunder or now or
hereafter existing at law or in equity or by statute. Every power or remedy given by the Indenture or any of the Collateral Agreements to Mortgagee or to which Mortgagee may otherwise be entitled, may be exercised, concurrently or independently,
from time to time and as often as may be deemed expedient by Mortgagee. In no event shall Mortgagee, in the exercise of the remedies provided in this Mortgage (including, without limitation, in connection with the assignment of Rents to Mortgagee,
or the appointment of a receiver and the entry of such receiver on to all or any part of the Mortgaged Property), be deemed a “beneficiary in possession,” and Mortgagee shall not in any way be made liable for any act, either of
commission or omission, in connection with the exercise of such remedies. 
 28. Multiple Security. If (a) the
Premises shall consist of one or more parcels, whether or not contiguous and whether or not located in the same county, or (b) in addition to this Mortgage, Mortgagee shall now or hereafter hold or be the beneficiary of one or more additional
deeds of trust, liens, mortgages or other security for the Obligations upon other property in the state where the Real Estate is located (whether or not such property is owned by Mortgagor or by others) or (c) both the circumstances described
in clauses (a) and (b) shall be true, then to the fullest extent permitted by law, Mortgagee may, at its election, commence or consolidate in a single foreclosure action all foreclosure proceedings against all such collateral securing the
Obligations (including the Mortgaged Property), which action may be brought or consolidated in the courts of any county in which any of such collateral is located. Mortgagor acknowledges that the right to maintain a consolidated foreclosure action
is a specific inducement to some or all of the Lenders to make certain loans to and to enter into certain agreements with Mortgagor, and for Mortgagee to enter into the Indenture, and Mortgagor expressly and irrevocably waives any objections to the
commencement or consolidation of the foreclosure proceedings in a single action and any objections to the laying of venue or based on 

  
 H-14

 
the grounds forum non conveniens which it may now or hereafter have. Mortgagor further agrees that if Mortgagee shall be prosecuting one or more foreclosure or other proceedings against a
portion of the Mortgaged Property or against any collateral other than the Mortgaged Property, which collateral secures the Obligations, or if Mortgagee shall have obtained a judgment of foreclosure and sale or similar judgment against such
collateral, then, whether or not such proceedings are being maintained or judgments were obtained in or outside the State in which the Premises are located, Mortgagee may commence or continue foreclosure proceedings and exercise its other remedies
granted in this Mortgage against all or any part of the Mortgaged Property and Mortgagor waives any objections to the commencement or continuation of a foreclosure of this Mortgage or exercise of any other remedies hereunder based on such other
proceedings or judgments, and waives any right to seek to dismiss, stay the execution of, remove, transfer or consolidate either any action under this Mortgage or such other proceedings on such basis. Neither the commencement nor continuation of
proceedings to foreclose this Mortgage nor the exercise of any other rights hereunder nor the recovery of any judgment by Mortgagee in any such proceedings shall prejudice, limit or preclude Mortgagee’s right to commence or continue one or more
foreclosure or other proceedings or obtain a judgment against any other collateral (either in or outside the state where the Real Estate is located) which secures the Obligations, and Mortgagor expressly waives any objections to the commencement of,
continuation of, or entry of a judgment in such other proceedings or exercise of any remedies in such proceedings based upon any action or judgment connected to this Mortgage, and Mortgagor also waives any right to seek to dismiss, stay the
execution of, remove, transfer or consolidate either such other proceedings or any action under this Mortgage on such basis. It is expressly understood and agreed that to the fullest extent permitted by law, Mortgagee may, at its election, cause the
sale of all collateral which is the subject of a single foreclosure action at either a single sale or at multiple sales conducted simultaneously and take such other measures as are appropriate in order to effect the agreement of the parties to

terms and provisions of this Mortgage to be performed by Mortgagor. Mortgagee may release, regardless of consideration and without the necessity for any notice to or consent by the beneficiary of any subordinate mortgage or the holder of any
subordinate lien on the Mortgaged Property, any part of the security held for the

lien or mortgage.

LAWS OF THE STATE IN WHICH THE REAL ESTATE IS LOCATED, EXCEPT THAT MORTGAGOR EXPRESSLY ACKNOWLEDGES THAT BY ITS TERMS THE INDENTURE SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF
CONFLICT OF LAW, AND FOR PURPOSES OF CONSISTENCY, MORTGAGOR AGREES THAT IN ANY IN PERSONAM PROCEEDING RELATED TO THIS MORTGAGE THE RIGHTS OF THE PARTIES TO THIS MORTGAGE SHALL ALSO BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK GOVERNING CONTRACTS MADE AND TO BE PERFORMED IN THAT STATE, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAW. 
 32. Waiver of Trial by Jury. Mortgagor and Mortgagee each hereby irrevocably and unconditionally waive trial by jury in any action, claim, suit or proceeding relating to this Mortgage and for any
counterclaim brought therein. Mortgagor hereby waives all rights to interpose any counterclaim in any suit brought by Mortgagee for foreclosure hereunder and all rights to have any such suit consolidated with any separate suit, action or proceeding.

other reasonable time, and from time to time, for the purpose of inspecting the Collateral and any and all records pertaining thereto and the operation of any Grantor’s business. Further, at such times as Agent deems advisable or necessary,
Agent shall cause to be conducted an appraisal of the Inventory of any Grantor and/or a field examination of any Grantor; provided that the Grantors shall be responsible for the expense of any such appraisal and/or field examination no more
than (i) one (1) time per year with respect to the Grantors’ Inventory, and (ii) one (1) time per year with respect to field examinations, unless in any case an Event of Default has occurred and is continuing, in which event
no such frequency limitation shall apply and the Grantors shall be responsible for any expenses associated with any and all appraisals and field examinations conducted pursuant to this Section 4.10. 

4.11 Insurance. 
 The assets and properties of each Grantor at all times shall be maintained in accordance with the requirements of all insurance carriers which provide insurance with respect to the assets and properties
of such Grantor so that such insurance shall remain in full force and effect. Each Grantor shall bear the full risk of any loss of any nature whatsoever with respect to the Collateral. At the Grantor’s own cost and expense in amounts and with
carriers reasonably acceptable to Agent, each Grantor shall (a) keep all its insurable properties and properties in which such Grantor has an interest insured against the hazards of fire, flood, sprinkler leakage, those hazards covered by
extended coverage insurance and such other hazards, and for such amounts, as is customary in the case of companies engaged in businesses similar to such Grantor’s including business interruption insurance; (b) maintain a bond in such
amounts as is customary in the case of companies engaged in businesses similar to such Grantor insuring against larceny, embezzlement or other criminal misappropriation of insured’s 

  
 - 13 -

 
officers and employees who may either singly or jointly with others at any time have access to the assets or funds of such Grantor either directly or through authority to draw upon such funds or
to direct generally the disposition of such assets; (c) maintain public and product liability insurance against claims for personal injury, death or property damage suffered by others; (d) maintain all such worker’s compensation or
similar insurance as may be required under the laws of any state or jurisdiction in which such Grantor is engaged in business; and (e) furnish Agent with (i) evidence of the maintenance of such policies by the renewal thereof before any
expiration date, and (ii) appropriate loss payable endorsements in form and substance satisfactory to Agent, naming Agent as an additional named insured and lender loss payee as its interests may appear with respect to all insurance coverage
referred to in clauses (a) and (c) above, and providing (A) that all proceeds thereunder shall be payable to Agent, (B) no such insurance shall be affected by any act or neglect of the insured or owner of the property described
in such policy, and (C) that such policy and loss payable clauses may not be cancelled, amended or terminated unless prior written notice is given to Agent in accordance with the terms and provisions of the applicable insurance policy(ies).
Each Grantor shall provide copies of all such insurance policies (including the appropriate lender loss payee, mortgagee and additional insured endorsements) within thirty (30) days after Agent’s reasonable request, however, only
certificates of insurance shall be required on the Closing Date. In the event of any loss thereunder, the carriers named therein hereby are directed by Agent and each Grantor to make payment for such loss to Agent and not to such Grantor and Agent
jointly. If any insurance losses are paid by check, draft or other instrument payable to any Grantor and Agent jointly, Agent may endorse such Grantor’s name thereon and do such other things as Agent may deem advisable to reduce the same to
cash. Agent is hereby authorized during the existence of an Event of Default to adjust and compromise claims under insurance coverage referred to in clauses (a) and (b) above. All loss recoveries received by Agent upon any such insurance
may be applied to the Obligations, in such order as Agent in its sole discretion shall determine. Any surplus shall be paid by Agent to the applicable Grantor or applied as may be otherwise required by law. Any deficiency thereon shall be paid by
the Grantors to Agent, on demand. Anything hereinabove to the contrary notwithstanding, and subject to the fulfillment of the conditions set forth below, Agent shall remit to the Grantors insurance proceeds received by Agent during any calendar year
under insurance policies procured and maintained by the Grantors which insure the Grantors’ insurable properties to the extent (i) no Event of Default 

  
 - 14 -

 or Default shall have occurred and be continuing and (ii) Undrawn Availability, both
prior to and after giving effect to any such payment, is equal to or greater than Twenty Million and 00/100 Dollars ($20,000,000.00). In the event either (i) an Event of Default or Default shall have occurred and be continuing or
(ii) Undrawn Availability, both prior to and after giving effect to any such payment, is less than Twenty Million and 00/100 Dollars ($20,000,000.00), then Agent may, in its sole discretion, either remit the insurance proceeds to Grantors upon
Grantors providing Agent with evidence reasonably satisfactory to Agent that the insurance proceeds will be used by the Grantors to repair, replace or restore the insured property which was the subject of the insurable loss, or apply the proceeds to
the Obligations, as aforesaid. The agreement of Agent to remit insurance proceeds in the manner above provided shall be subject in each instance to satisfaction of the condition that the Grantors shall use such insurance proceeds to repair, replace
or restore the insurable property which was the subject of the insurable loss and for no other purpose. 
 4.12
Failure to Pay Insurance. 
 If any Grantor fails to obtain insurance as hereinabove provided, or to keep
the same in force, Agent, if Agent so elects, may obtain such insurance and pay the premium therefor on behalf of such Grantor, and charge Borrower’s Account therefor as a Revolving Advance of a Domestic Rate Loan and such expenses so paid
shall be part of the Obligations. 
 4.13 Payment of Taxes 

Each Grantor will pay, when due, all taxes, assessments and other Charges lawfully levied or assessed upon such Grantor or
any of the Collateral including real and personal property taxes, assessments and charges and all franchise, income, employment, social security benefits, withholding, and sales taxes. If any tax by any Governmental Body is or may be imposed on or
as a result of any transaction between any Grantor and Agent or any Lender which Agent or any Lender may be required to withhold or pay or if any taxes, assessments, or other Charges remain unpaid after the date fixed for their payment, or if any
claim shall be made which, in Agent’s or any Lender’s opinion, may possibly create a valid Lien on the Collateral, Agent may without notice to any Grantor pay the taxes, assessments or other Charges and each Grantor hereby indemnifies and
holds Agent and each Lender harmless in respect thereof. Agent will not pay any taxes, assessments or 

  
 - 15 -

 
Charges to the extent that any Grantor has Properly Contested those taxes, assessments or Charges. The amount of any payment by Agent under this Section 4.13 shall be charged to
Borrower’s Account as a Revolving Advance maintained as a Domestic Rate Loan and added to the Obligations and, until the Grantors shall furnish Agent with an indemnity therefor (or supply Agent with evidence satisfactory to Agent that due
provision for the payment thereof has been made), Agent may hold without interest any balance standing to the Borrower’s credit and Agent shall retain its security interest in and Lien on any and all Collateral held by Agent. 

4.14 Payment of Leasehold Obligations. 

Each Grantor shall at all times pay, when and as due, its rental obligations under all leases under which it is a tenant,
and shall otherwise comply, in all material respects, with all other terms of such leases and keep them in full force and effect and, at Agent’s request will provide evidence of having done so. 

4.15 Receivables. 
 (a) Nature of Receivables. Each of the Receivables shall be a bona fide and valid account representing a bona fide indebtedness incurred by the Customer therein named, for a fixed sum as set forth

 (d) Collection of Receivables. Prior to a Cash Dominion Event, each Grantor will, at such
Grantor’s sole cost and expense, collect all amounts due on Receivables; provided, however, that to the extent such Grantor deposits such amounts in an account, such account shall be an account with respect to which a Blocked Account Agreement
has been entered into but will not go into effect until the occurrence of a Cash Dominion Event. Upon the occurrence of a Cash Dominion Event and until, as applicable, no Event of Default shall have occurred and be continuing or upon the occurrence
of a Testing Event Cure, each Grantor shall deliver to the Agent, or deposit in the Blocked Account, on Agent’s behalf and for Agent’s account, in original form and on the date of receipt thereof, all checks, drafts, notes, money orders,
acceptances, cash and other evidences of Indebtedness payable to such Grantor on Receivables, and shall not commingle such collections with such Grantor’s funds or use the same except to pay Obligations. 

(e) Notification of Assignment of Receivables. At any time upon the occurrence and during the continuance of an
Event of Default, Agent shall have the right to send notice of the assignment of, and Agent’s security interest in and Lien on, the Receivables to any and all Customers or any third party holding or otherwise concerned with any of the
Collateral. Thereafter, Agent shall have the sole right to collect the Receivables, take possession of the Collateral, or both. Agent’s actual collection expenses, including, but not limited to, stationery and postage, telephone and telegraph,
secretarial and clerical expenses and the salaries of any collection personnel used for collection, may be charged to Borrower’s Account and added to the Obligations.

continuance of an Event of Default, Agent shall have the right to receive, endorse, assign and/or deliver in the name of Agent or any Grantor any and all checks, drafts and other instruments for the payment of money relating to the Receivables, and

during the continuance of an Event of Default, (i) to endorse such Grantor’s name upon any notes, acceptances, 

  
 - 17 -

against Customers, assignments and verifications of Receivables; (iii) to send verifications of Receivables to any Customer; (iv) to sign such Grantor’s name on all financing statements or any other documents or instruments deemed
necessary or appropriate by Agent to preserve, protect, or perfect Agent’s interest in the Collateral and to file same; (v) to demand payment of the Receivables; (vi) to enforce payment of the Receivables by legal proceedings or
otherwise; (vii) to exercise all of such Grantor’s rights and remedies with respect to the collection of the Receivables and any other Collateral; (viii) to settle, adjust, compromise, extend or renew the Receivables; (ix) to

attorney or designee are hereby ratified and approved, and said attorney or designee shall not be liable for any acts of omission or commission nor for any error of judgment or mistake of fact or of law, unless done maliciously or with gross (not
mere) negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment); this power being coupled with an interest is irrevocable while any of the Obligations remain unpaid. Agent shall have the right at any time,
after the occurrence and during the continuance of an Event of Default, to change the address for delivery of mail addressed to any Grantor to such address as Agent may designate and to receive, open and dispose of all mail addressed to any Grantor.

 (g) No Liability. Neither Agent nor any Lender shall, under any circumstances or in any event
whatsoever, have any liability for any error or omission or delay of any kind occurring in the settlement, collection or payment of any of the Receivables or any instrument received in payment thereof, or for any damage resulting therefrom, except
to the extent that any of the foregoing arises out of the willful misconduct or gross negligence of Agent or any Lender. At any time after the occurrence and during the continuance of an Event of Default, Agent may, without notice or consent from
any Grantor, sue upon or otherwise collect, extend the time of payment of, compromise or settle for cash, credit or upon any terms any of the Receivables or any other securities, 

  
 - 18 -

 
instruments or insurance applicable thereto and/or release any obligor thereof. At any time after the occurrence and during the continuance of an Event of Default, Agent is authorized and

received such proceeds directly, they shall be deposited by such Grantor into) either a lockbox account, dominion account or such other “blocked account” (“Blocked Accounts”) established at a bank or banks (each such bank, a
“Blocked Account Bank”) pursuant to an arrangement with such Blocked Account Bank as may be selected by such Grantor and be acceptable to Agent. Each Grantor, Agent and each Blocked Account Bank shall enter into a deposit account control
agreement (each, a “Deposit Account Control Agreement”) in form and substance satisfactory to Agent directing such Blocked Account Bank to transfer such funds so deposited to Agent, either to any account maintained by Agent at said Blocked
Account Bank or by wire transfer to appropriate account(s) of Agent. All funds deposited in such Blocked Accounts shall immediately become the property of Agent and each Grantor shall obtain the agreement by such Blocked Account Bank to waive any
offset rights against the funds so deposited. Neither Agent nor any Lender assumes any responsibility for such blocked account arrangement, including any claim of accord and satisfaction or release with respect to deposits accepted by any Blocked
Account Bank thereunder. Alternatively, upon the occurrence of a Cash Dominion Event and until, as applicable, no Event of Default shall have occurred and be continuing or upon the occurrence of a Testing Event Cure, Agent may establish depository

granted unto Mortgagee, its successors and assigns for the uses and purposes set forth, until the Obligations are fully paid and performed. 
 Terms and Conditions 
 Mortgagor further represents, warrants, covenants
and agrees with Mortgagee as follows:

times and places and in the manner specified in the Credit Agreement and the Other Documents, as applicable. 
 3.
Requirements. 
  

	 	(a)	Mortgagor shall promptly comply with, or cause to be complied with, and conform to all present and future laws, statutes, codes, ordinances, orders, judgments, decrees,
rules, regulations and requirements, and irrespective of the nature of the work to be done, of each of the United States of America, any state and any municipality, local government or other political subdivision thereof and any agency, department,
bureau, board, commission or other instrumentality of any of them, now existing or subsequently created (collectively, “Governmental Authority”) which has jurisdiction over the Mortgaged Property and all covenants, restrictions and
conditions now or later of record which may be applicable to any of the Mortgaged Property, or to the use, manner of use, occupancy, possession, operation, maintenance, alteration, repair or reconstruction of any of the Mortgaged Property, the
failure to comply with which could have a material adverse affect on Mortgagor’s continued operations at the Mortgaged Property or on the validity or enforceability of this Mortgage, the Credit Agreement or any of the Other Documents or any of
the rights and remedies of the Agent and the Lenders hereunder or thereunder. All present and future laws, statutes, codes, ordinances, orders, judgments, decrees, rules, regulations and requirements of every Governmental Authority applicable to
Mortgagor or to any of the Mortgaged Property and all covenants, restrictions, and conditions which now or later may be applicable to any of the Mortgaged Property are collectively referred to as the “Legal Requirements.”

  
 4 

	 	(b)	From and after the date of this Mortgage, Mortgagor shall not by act or omission permit any building or other improvement on any premises not subject to the lien
created by this Mortgage to rely on the Premises or any part thereof or any interest therein to fulfill any Legal Requirement, and Mortgagor hereby assigns to Mortgagee any and all rights to give consent for all or any portion of the Premises or any
interest therein to be so used. Mortgagor shall not by act or omission impair the integrity of any of the Real Estate as a single zoning lot separate and apart from all other premises. Mortgagor represents that each parcel of the Real Estate
constitutes a legally subdivided lot, in compliance with all subdivision laws and similar Legal Requirements. Any act or omission by Mortgagor which would result in a violation of any of the provisions of this subsection shall be void.

 4. Payment of Taxes and Other Impositions. 

 

	 	(a)	Promptly when due, Mortgagor shall pay and discharge all taxes, assessments and governmental charges imposed upon or assessed against or which may become a lien on any
of the Mortgaged Property, or arising in respect of the occupancy, use or possession thereof (all of the foregoing are collectively referred to as the “Impositions”) in accordance with Section 4.13 of the Credit Agreement. If
by law any Imposition, at Mortgagor’s option, may be paid in installments (whether or not interest shall accrue on the unpaid balance of such Imposition), Mortgagor may elect to pay such Imposition in such installments and shall be responsible
for the payment of such installments with interest, if any. 

  

	 	(b)	If Mortgagor is in default of its obligation to pay and discharge Impositions as required under this Section 5, then Mortgagee, at its option, may pay any
Imposition after the date such Imposition shall have become due. Any sums paid by Mortgagee in discharge of any Impositions shall be payable on demand by Mortgagor to Mortgagee together with interest at the Default Rate. 

 

	 	(c)	Mortgagor shall not claim, demand or be entitled to receive any credit or credits toward the satisfaction of this Mortgage or on any interest payable thereon for any
taxes assessed against the Mortgaged Property or any part thereof, and shall not claim, to the extent any such claim could materially affect the lien of this Mortgage, any deduction from the taxable value of the Mortgaged Property by reason of this
Mortgage. 

 5. Insurance. 
  

	 	(a)	 Mortgagor shall maintain insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of
Mortgagor, are adequate and appropriate for the conduct of the business of Mortgagor in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality thereof, in such amounts, with such

  
 5 

	 	
deductibles, and by such methods as shall be customary, in the good faith judgment of Mortgagor, for companies similarly situated in the industry in which Mortgagor is engaged.

  

	 	(b)	If any portion of the Premises is located in a federally designated special flood hazard area, the Mortgagor shall keep the improvements on the Premises insured against
loss by flood in an amount at least equal to the outstanding Obligations or the maximum limit of coverage available with respect to such improvements under the applicable federal statute, whichever is less. 

 

	 	(c)	Mortgagor will cause any property and casualty insurance policies with respect to the Mortgaged Property to be endorsed or otherwise amended to include a
“standard” lender’s loss payable endorsement, which endorsement or policy shall provide that if the insurance carrier shall have received written notice from Mortgagee of the occurrence of an Event of Default, the insurance carrier
shall pay all proceeds otherwise payable to Mortgagor under such policies directly to the Trustee. Mortgagor shall cause all such policies to provide that neither Mortgagor, Mortgagee nor any other party shall be a coinsurer thereunder and to
contain a “Replacement Cost Endorsement” or similar endorsement without any deduction for depreciation. Liability insurance policies shall name Mortgagee as an additional insured and contain a waiver of subrogation against Mortgagee.

  

	 	(d)	If Mortgagor is in default of its obligations to insure as required under this Section 5, then Mortgagee, at its option, may effect such insurance from year to
year, and pay the premium or premiums therefor, and Mortgagor shall pay to Mortgagee on demand such premium or premiums so paid by Mortgagee with interest from the time of payment at the Default Rate. 

 

	 	(e)	In the event of foreclosure of this Mortgage or other transfer of title to the Mortgaged Property, all right, title and interest of Mortgagor in and to any insurance
policies then in force shall pass to the purchaser or grantee. 

 6. Restrictions on Liens and Encumbrances.
Except for the lien of this Mortgage and the Permitted Liens, and except as expressly permitted under the Credit Agreement, Mortgagor shall not further mortgage, nor otherwise encumber the Mortgaged Property nor create or suffer to exist any lien,
charge or encumbrance on the Mortgaged Property, or any part thereof, whether superior or subordinate to the lien created by this Mortgage and whether recourse or non-recourse. 
 7. Due on Sale and Other Transfer Restrictions. Except as expressly permitted under the Credit Agreement, Mortgagor shall not sell, transfer, convey or assign all or any portion of, or any interest
in, the Mortgaged Property. 
 8. Maintenance; No Alteration; Inspection; Utilities. 

(a) Mortgagor shall maintain or cause to be maintained all the Improvements in good condition and repair and shall not commit or suffer
any waste of the Improvements. Mortgagor shall repair, restore, replace or rebuild promptly any part of the 

  
 6 

 
Premises which may be damaged or destroyed by casualty. The Improvements shall not be demolished (without replacing) or altered, nor any additions built, which in any of the foregoing events
would materially reduce the fair market value of the Mortgaged Property. 
 (b) Mortgagee and any persons authorized by
Mortgagee shall have the right upon reasonable notice to enter and inspect the Premises and all work done, labor performed and materials furnished in and about the Improvements. 

(c) Mortgagor shall pay or cause to be paid when due all utility charges which are incurred for gas, electricity, water or sewer services
furnished to the Premises and all other assessments or charges of a similar nature, whether public or private, affecting the Premises or any portion thereof, whether or not such assessments or charges are liens thereon. 

9. Condemnation/Eminent Domain. Promptly upon obtaining knowledge of the institution of any proceedings for the condemnation of the
Mortgaged Property, or any portion thereof, Mortgagor will notify Mortgagee of the pendency of such proceedings. Mortgagee is hereby authorized and empowered by Mortgagor to settle or compromise any claim in connection with such condemnation and to
receive all awards and proceeds thereof to be held by Mortgagee as collateral to secure the payment and performance of the Obligations. Notwithstanding the preceding sentence, provided no Event of Default shall have occurred and be continuing,
Mortgagor shall, at its expense, diligently prosecute any proceeding relating to such condemnation, settle or compromise any claims in connection therewith and receive any awards or proceeds thereof, provided that Mortgagor shall promptly repair and
restore the Mortgaged Property to its condition prior to such condemnation, regardless of whether any award shall have been received or whether such award is sufficient to pay for the costs of such repair and restoration. 

10. Restoration. Mortgagor shall use all insurance proceeds and all condemnation proceeds and awards to restore the Mortgaged
Property promptly to its condition prior to such casualty or condemnation (giving effect to the remaining configuration of the Premises after such condemnation), and in compliance with all Legal Requirements. 

11. Further Assurances. To further assure Mortgagee’s rights under this Mortgage, Mortgagor agrees upon demand of Mortgagee to
do any act or execute any additional documents (including, but not limited to, security agreements on any personalty included or to be included in the Mortgaged Property and a separate assignment of each Lease in recordable form) as may be required
by Mortgagee to confirm the lien of this Mortgage and all other rights or benefits conferred on Mortgagee. 
 12.
Mortgagee’s Right to Perform. Upon the occurrence and during the continuation of an Event of Default, Mortgagee may, at any time, but shall be under no obligation to, pay or perform any of the covenants or agreements of Mortgagor,
without waiving or releasing Mortgagor from any obligation or default under this Mortgage, and the amount or cost thereof, with interest at the Default Rate, shall immediately be due from Mortgagor to Mortgagee and the same shall be secured by this
Mortgage and shall be an encumbrance on the Mortgaged Property prior to any right, title to, interest in or claim upon the Mortgaged Property 

  
 7 

 
attaching subsequent to the date of this Mortgage. No payment or advance of money by Mortgagee under this Section shall be deemed or construed to cure Mortgagor’s default or waive any right
or remedy of Mortgagee. 
 13. Secured Amount. The maximum aggregate amount of all indebtedness that is, or under any
contingency may be secured at the date hereof or at any time hereafter by this Mortgage is $[            ] (the “Secured Amount”), plus, to the extent permitted by
applicable law, collection costs, sums advanced for the payment of taxes, assessments, maintenance and repair charges, insurance premiums and any other costs incurred to protect the security encumbered hereby or the lien hereof, expenses incurred by
the Mortgagee by reason of any default by the Mortgagor under the terms hereof, together with interest thereon, all of which amount shall be secured hereby. So long as the aggregate amount of the Obligations exceeds the Secured Amount, any payments
and repayments of the Obligations shall not be deemed to be applied against or to reduce the Secured Amount. 
 14. Events of
Default. The occurrence of an Event of Default under the Credit Agreement shall constitute an Event of Default hereunder. 

15. Remedies. 
 (a) Upon the occurrence and during the continuation of an Event of Default, in addition to any other rights and remedies Mortgagee may have pursuant to the Credit Agreement or any of the Other Documents,
or as provided by law, and without limitation, Mortgagee may immediately take such action, without notice or demand, as it deems advisable to protect and enforce its rights against Mortgagor and in and to the Mortgaged Property, including, but not
limited to, the following actions, each of which may be pursued concurrently or otherwise, at such time and in such manner as Mortgagee may determine, in its sole discretion, without impairing or otherwise affecting the other rights and remedies of
Mortgagee: 
 (i) Mortgagee may elect to cause the Mortgaged Property or any part thereof to be sold as follows: 

(A) Mortgagee may proceed as if all of the Mortgaged Property were real property in accordance with subparagraph (C) below, or
Mortgagee may elect to treat any of the Mortgaged Property which consists of a right in action or which is property that can be severed from the Real Estate without causing structural damage thereto as if the same were personal property, and dispose
of the same in accordance with the provisions of this Mortgage which relate to the exercise of remedies with respect to that portion of the Mortgaged Property which is personal property, separate and apart from the sale of real property. 

(B) Mortgagee may cause any such sale or other disposition to be conducted immediately following the expiration of any grace period, if
any, herein provided, and any advertisement, the giving of any notices and the expiration of any time period required by law or herein, or Mortgagee may delay any such sale or other disposition for such period of time as Mortgagee deems to be
appropriate. Should Mortgagee desire that more than one (1) such sale or other disposition be conducted, Mortgagee may, at its option, cause the same to be conducted simultaneously, or successively, on the same day, or at such different days or
times and in such order as Mortgagee may deem to be appropriate. 

  
 8 

 (C) Should Mortgagee elect to sell the Mortgaged Property or any part thereof which is real
property or which Mortgagee has elected to treat as real property, upon such election, the Mortgagee shall give such notice of default and election to sell as may then be required by law. Thereafter, upon the expiration of such time and the giving
of the required notice(s) and after having advertised the sale as required by law, and without the necessity of any demand on Mortgagor except as required herein or by law, Mortgagee, at the time and place specified in the notice of sale, shall sell
the Mortgaged Property or any portion thereof specified by Mortgagee, at public auction to the highest bidder for cash in lawful money of the United States. Mortgagee may, from time to time, postpone the sale by public announcement thereof at the
time and place noticed therefor. If the Mortgaged Property consists of several lots or parcels, Mortgagee may designate the order in which such lots or parcels shall be offered for sale or sold. Any person, including Mortgagor or Mortgagee, may
purchase at the sale. Upon any sale, Mortgagee shall execute and deliver to the purchaser or purchasers a deed or deeds conveying the property so sold, but without any covenant or warranty whatsoever, express or implied, whereupon such purchaser or
purchasers shall be entitled to immediate possession. 
 (D) In the event of a sale or other disposition of the Mortgaged
Property, or any part thereof, and the execution of a deed or other conveyance pursuant thereto, the recitals therein of facts, such as default, the giving of notice of default and notice of sale, demand that such sale should be made, postponement
of sale, terms of sale, sale, purchase, payment of purchase money and other facts affecting the regularity or validity of such sale or disposition, shall be conclusive proof of the truth of such facts; any such deed or conveyance shall be conclusive
against all persons as to such facts recited therein. 
 (E) The acknowledgment of the receipt of the purchase money, contained
in any deed or conveyance executed as aforesaid, shall be sufficient discharge to the grantee from all obligations to see to the proper application of the consideration therefor as hereinafter provided. 

(ii) Mortgagee may, to the extent permitted by applicable law, (A) institute and maintain an action of judicial foreclosure against
all or any part of the Mortgaged Property, (B) institute and maintain an action on the Notes, (C) sell all or part of the Mortgaged Property (Mortgagor expressly granting to Mortgagee the power of sale) as set forth above or (D) take
such other action at law or in equity for the enforcement of this Mortgage, the Credit Agreement or any of the Other Documents as the law may allow. Mortgagee may proceed in any such action to final judgment and execution thereon for all sums due
hereunder, together with interest thereon at the Default Rate and all costs of suit, including, without limitation, reasonable attorneys’ fees and disbursements. Interest at the Default Rate shall be due on any judgment obtained by Mortgagee
from the date of judgment until actual payment is made of the full amount of the judgment. 

  
 9 

 (iii) Mortgagee may, to the extent permitted by applicable law, personally, or by its
agents, attorneys and employees and without regard to the adequacy or inadequacy of the Mortgaged Property or any other collateral as security for the Obligations enter into and upon the Mortgaged Property and each and every part thereof and exclude
Mortgagor and its agents and employees therefrom without liability for trespass, damage or otherwise (Mortgagor hereby agreeing to surrender possession of the Mortgaged Property to Mortgagee upon demand at any such time) and use, operate, manage,
maintain and control the Mortgaged Property and every part thereof. Following such entry and taking of possession, Mortgagee shall be entitled, without limitation, (A) to lease all or any part or parts of the Mortgaged Property for such periods
of time and upon such conditions as Mortgagee may, in its discretion, deem proper, (B) to enforce, cancel or modify any Lease and (C) generally to execute, do and perform any other act, deed, matter or thing concerning the Mortgaged
Property as Mortgagee shall deem appropriate as fully as Mortgagor might do. 
 (iv) Upon the completion of any sale or sales
made by Mortgagee, as the case may be, under or by virtue of this subsection (a), Mortgagee or any officer of any court empowered to do so, shall execute and deliver as aforesaid, to the accepted purchaser or purchasers a good and sufficient
instrument, or good and sufficient instruments, conveying, assigning and transferring all estate, right, title and interest in and to the property and rights sold. Mortgagee is hereby appointed irrevocably the true and lawful attorney of Mortgagor
in its name and stead to make all necessary conveyances, assignments, transfers and deliveries of the Mortgaged Property or any part thereof and the rights so sold and for that purpose, Mortgagee may execute all necessary instruments of conveyance,
assignment and transfer, and may substitute one or more persons with like power, Mortgagor hereby ratifying and confirming all that its attorney or any substitute or substitutes shall lawfully do by virtue hereof. Nevertheless, Mortgagor, if so
requested by Mortgagee, shall ratify and confirm any such sale or sales by executing and delivering to Mortgagee or to such purchaser or purchasers all such instruments as may be advisable, in the judgment of Mortgagee, for the purpose as may be
designated in such request. 
 (v) Mortgagor hereby expressly waives any right which it may have to direct the order in which
any of the Mortgaged Property shall be sold in the event of any sale or sales pursuant hereto. 
 (b) Mortgagee, in any action
to foreclose this Mortgage in a judicial procedure or in connection with the exercise of any power of sale, shall be entitled to the appointment of a receiver. In case of a trustee’s sale or foreclosure sale, the Real Estate may be sold, at
Mortgagee’s election, in one parcel or in more than one parcel and Mortgagee is specifically empowered (without being required to do so, and in its sole and absolute discretion) to cause successive sales of portions of the Mortgaged Property to
be held. 
 (c) In the event of any breach of any of the covenants, agreements, terms or conditions contained in this Mortgage,
Mortgagee shall be entitled to enjoin such breach and obtain specific performance of any covenant, agreement, term or condition and Mortgagee shall have the right to invoke any equitable right or remedy as though other remedies were not provided for
in this Mortgage. 

  
 10 

 16. Right of Mortgagee to Credit Sale. Upon the occurrence of any sale made under
this Mortgage, whether made under the power of sale or by virtue of judicial proceedings or of a judgment or decree of foreclosure and sale, Mortgagee may bid for and acquire the Mortgaged Property or any part thereof. In lieu of paying cash
therefor, Mortgagee may make settlement for the purchase price by crediting upon the Obligations or other sums secured by this Mortgage the net sales price after deducting therefrom the expenses of sale and the cost of the action and any other sums
that Mortgagee is authorized to deduct under this Mortgage. In such event, this Mortgage, the Credit Agreement, and documents evidencing the Obligations and the other expenditures secured hereby may be presented to the person or persons conducting
the sale in order that the amount so used or applied may be credited upon the Obligations as having been paid. 
 17.
Appointment of Receiver. If an Event of Default shall have occurred and be continuing, Mortgagee as a matter of right and without notice to Mortgagor, unless otherwise required by applicable law, and without regard to the adequacy or
inadequacy of the Mortgaged Property or any other collateral as security for the Obligations or the interest of Mortgagor therein, shall have the right to apply to any court having jurisdiction to appoint a receiver or receivers or other manager of
the Mortgaged Property, and Mortgagor hereby irrevocably consents to such appointment and waives notice of any application therefor (except as may be required by law). Any such receiver or receivers shall have all the usual powers and duties of
receivers in like or similar cases and all the powers and duties of Mortgagee in case of entry as provided in this Mortgage, including, without limitation and to the extent permitted by law, the right to enter into leases of all or any part of the
Mortgaged Property and exercise all such powers until the date of confirmation of sale of the Mortgaged Property unless such receivership is sooner terminated. 
 18. Extension, Release, etc. 
 (a) Without affecting the lien or charge of
this Mortgage upon any portion of the Mortgaged Property not then or theretofore released as security for the full amount of the Obligations, Mortgagee may, from time to time and without notice, agree to (i) release any person liable for any
portion of the Obligations, (ii) extend the maturity or alter any of the terms of the indebtedness guaranteed under any guaranty of any of the Obligations, (iii) grant other indulgences, (iv) release or reconvey, or cause to be
released or reconveyed at any time at Mortgagee’s option any parcel, portion or all of the Mortgaged Property, (v) take or release any other or additional security for any Obligation herein mentioned, or (vi) make compositions or
other arrangements with debtors in relation thereto. If at any time this Mortgage shall secure less than all of the principal amount of the Obligations, it is expressly agreed that any repayments of the principal amount of the Obligations shall not
reduce the amount of the encumbrance created by this Mortgage until the encumbrance amount shall equal the principal amount of the Obligations outstanding. 
 (b) No recovery of any judgment by Mortgagee and no levy of an execution under any judgment upon the Mortgaged Property or upon any other property of Mortgagor shall affect the encumbrance of this
Mortgage or any liens, rights, powers or remedies of Mortgagee hereunder, and such liens, rights, powers and remedies shall continue unimpaired. 

  
 11 

 (c) If Mortgagee shall have the right to foreclose this Mortgage, Mortgagor authorizes
Mortgagee at its option to foreclose the lien of this Mortgage subject to the rights of any tenants of the Mortgaged Property. The failure to make any such tenants parties defendant to any such foreclosure proceeding and to foreclose their rights
will not be asserted by Mortgagor as a defense to any proceeding instituted by Mortgagee to collect the Obligations or to foreclose the lien of this Mortgage. 
 (d) Unless expressly provided otherwise, in the event that ownership of this Mortgage and title to the Mortgaged Property or any estate therein shall become vested in the same person or entity, this
Mortgage shall not merge in such title but shall continue as a valid lien on the Mortgaged Property for the amount secured hereby. 
 19. Fixture Filing. To the extent any of the Mortgaged Property constitutes “fixtures” within the meaning of the Uniform Commercial Code (the “Code”) of the state
where the Real Estate is located, then this Mortgage is to be filed and effective as a financing statement filed as a fixture filing within the meaning of the Code. The Mortgagor is the “Debtor,” and the address of the Debtor set
forth in the initial paragraph of this Mortgage is the mailing address of the Debtor. The Mortgagee is the “Secured Party” and the place of business of the Mortgagee set forth in the initial paragraph of this Mortgage is an address
of the Secured Party from which information concerning the security interest may be obtained. 
 20. Assignment of Rents.
Mortgagor hereby assigns to Mortgagee the Rents as further security for the payment and performance of all of the Obligations, and Mortgagor grants to Mortgagee the right to enter the Mortgaged Property for the purpose of collecting the same and to
let the Mortgaged Property or any part thereof, and to apply the Rents on account of the Obligations. The foregoing assignment and grant is present and absolute and shall continue in effect until the Obligations are paid and performed in full, but
Mortgagee hereby waives the right to enter the Mortgaged Property for the purpose of collecting the Rents, and Mortgagor shall be entitled to collect, receive, use and retain the Rents unless an Event of Default shall be in effect; such right of
Mortgagor to collect, receive, use and retain the Rents may be revoked by Mortgagee if an Event of Default occurs by giving not less than five days’ written notice of such revocation to Mortgagor, in the event such notice is given, Mortgagor
shall pay over to Mortgagee, or to any receiver appointed to collect the Rents, the Rents and any lease security deposits. Mortgagor shall not accept prepayments of installments of Rent to become due for a period of more than one month in advance
(except for security deposits and estimated payments of percentage rent, if any). 
 21. Trust Funds. To the extent
required under applicable law, all lease security deposits of the Real Estate shall be treated as trust funds not to be commingled with any other funds of Mortgagor. Within 10 days after request by Mortgagee, Mortgagor shall furnish Mortgagee
satisfactory evidence of compliance with this section, together with a statement of all lease security deposits by lessees and copies of all Leases not previously delivered to Mortgagee, which statement shall be certified by Mortgagor. 

22. Additional Rights. The holder of any subordinate lien or subordinated mortgage on the Mortgaged Property shall have no right to
terminate any Lease whether or not such Lease is subordinate to this Mortgage, nor shall Mortgagor consent to any holder of any 

  
 12 

 
subordinate lien joining any tenant under any Lease in any action to foreclose such lien or modify, interfere with, disturb or terminate the rights of any tenant under any Lease. By recordation
of this Mortgage all subordinate lienholders and the beneficiaries under subordinate mortgages are subject to and notified of this provision, and any action taken by any such lienholder or beneficiary contrary to this provision shall be null and
void. If an Event of Default occurs and is continuing, Mortgagee may, in its sole discretion and without regard to the adequacy of its security under this Mortgage, apply all or any part of any amounts on deposit with Mortgagee under this Mortgage
against the Obligations as more fully set forth in the Credit Agreement. Any such application shall not be construed to cure or waive any Default or Event of Default or invalidate any act taken by Mortgagee on account of such Default or Event of
Default. 
 23. Notices. All notices or other communications hereunder shall be given in the manner and to the addresses
determined under the Credit Agreement. 
 24. No Oral Modification. This Mortgage may not be changed or terminated orally.
Any agreement made by Mortgagor and Mortgagee after the date of this Mortgage relating to this Mortgage shall be superior to the rights of the holder of any intervening or subordinate lien or encumbrance. 

25. Partial Invalidity. In the event any one or more of the provisions contained in this Mortgage shall for any reason be held to
be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof, but each shall be construed as if such invalid, illegal or unenforceable provision had never been
included. Notwithstanding anything to the contrary contained in this Mortgage, the Credit Agreement or any of the Other Documents, the obligations of Mortgagor and of any other obligor under the Credit Agreement and the Other Documents shall be
subject to the limitation that Mortgagee shall charge, take or receive, and neither Mortgagor nor any other obligor shall be obligated to pay to Mortgagee, any amounts constituting interest in excess of the maximum rate permitted by law to be
charged by Mortgagee. 
 26. Mortgagor’s Waiver of Rights. To the fullest extent permitted by law, Mortgagor waives
the benefit of all laws now existing or that may subsequently be enacted providing for (i) any appraisement before sale of any portion of the Mortgaged Property, (ii) any extension of the time for the enforcement of the collection of the
Obligations or the creation or extension of a period of redemption from any sale made in collecting such debt and (iii) exemption of the Mortgaged Property from attachment, levy or sale under execution or exemption from civil process. To the
full extent Mortgagor may do so, Mortgagor agrees that Mortgagor will not at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any appraisement, valuation, stay of execution,
exemption, extension or redemption, or requiring foreclosure of this Mortgage before exercising any other remedy granted hereunder and Mortgagor, for Mortgagor and its successors and assigns, and for any and all persons ever claiming any interest in
the Mortgaged Property, to the extent permitted by law, hereby waives and releases all rights of redemption, valuation, appraisement, stay of execution, notice of election to mature or declare due the whole of the secured indebtedness and
marshalling in the event of exercise by Mortgagee of the power of sale or other rights hereby created. Mortgagor further waiver, to the extent permitted by applicable 

  
 13 

 
law, all errors and imperfections in any proceedings instituted by Mortgagee under this Mortgage, and all notices of any Event of Default (except as may be provided for under this Mortgage) or of
Mortgagee’s election to exercise its actual exercise of any right, remedy or recourse provided for under this Mortgage. 

27. Remedies Not Exclusive. Mortgagee shall be entitled to enforce payment and performance of all of the Obligations and to
exercise all rights and powers under this Mortgage, or under any of the Security Documents, or other agreement or any laws now or hereafter in force, notwithstanding some or all of the Obligations may now or hereafter be otherwise secured, whether
by mortgage, security agreement, pledge, lien, assignment or otherwise. Neither the acceptance of this Mortgage nor its enforcement, shall prejudice or in any manner affect Mortgagee’s right to realize upon or enforce any other security now or
hereafter held by Mortgagee, it being agreed that Mortgagee shall be entitled to enforce this Mortgage and any other security now or hereafter held by Mortgagee in such order and manner as Mortgagee may determine in its absolute discretion. No
remedy herein conferred upon or reserved to Mortgagee is intended to be exclusive of any other remedy herein or by law provided or permitted, but each shall be cumulative and shall be in addition to every other remedy given hereunder or now or
hereafter existing at law or in equity or by statute. Every power or remedy given by the Credit Agreement or any of the Other Documents to Mortgagee or to which Mortgagee may otherwise be entitled, may be exercised, concurrently or independently,
from time to time and as often as may be deemed expedient by Mortgagee. In no event shall Mortgagee, in the exercise of the remedies provided in this Mortgage (including, without limitation, in connection with the assignment of Rents to Mortgagee,
or the appointment of a receiver and the entry of such receiver on to all or any part of the Mortgaged Property), be deemed a “beneficiary in possession,” and Mortgagee shall not in any way be made liable for any act, either of
commission or omission, in connection with the exercise of such remedies. 
 28. Multiple Security. If (a) the
Premises shall consist of one or more parcels, whether or not contiguous and whether or not located in the same county, or (b) in addition to this Mortgage, Mortgagee shall now or hereafter hold or be the beneficiary of one or more additional
deeds of trust, liens, mortgages or other security for the Obligations upon other property in the state where the Real Estate is located (whether or not such property is owned by Mortgagor or by others) or (c) both the circumstances described
in clauses (a) and (b) shall be true, then to the fullest extent permitted by law, Mortgagee may, at its election, commence or consolidate in a single foreclosure action all foreclosure proceedings against all such collateral securing the
Obligations (including the Mortgaged Property), which action may be brought or consolidated in the courts of any county in which any of such collateral is located. Mortgagor acknowledges that the right to maintain a consolidated foreclosure action
is a specific inducement to some or all of the Lenders to make certain loans to and to enter into certain agreements with Mortgagor, and for Mortgagee to enter into the Credit Agreement, and Mortgagor expressly and irrevocably waives any objections
to the commencement or consolidation of the foreclosure proceedings in a single action and any objections to the laying of venue or based on the grounds forum non conveniens which it may now or hereafter have. Mortgagor further agrees that if
Mortgagee shall be prosecuting one or more foreclosure or other proceedings against a portion of the Mortgaged Property or against any collateral other than the Mortgaged Property, which collateral secures the Obligations, or if Mortgagee shall have
obtained a judgment of foreclosure and sale or similar judgment against such collateral, then, 

  
 14 

 
whether or not such proceedings are being maintained or judgments were obtained in or outside the State in which the Premises are located, Mortgagee may commence or continue foreclosure
proceedings and exercise its other remedies granted in this Mortgage against all or any part of the Mortgaged Property and Mortgagor waives any objections to the commencement or continuation of a foreclosure of this Mortgage or exercise of any other
remedies hereunder based on such other proceedings or judgments, and waives any right to seek to dismiss, stay the execution of, remove, transfer or consolidate either any action under this Mortgage or such other proceedings on such basis. Neither
the commencement nor continuation of proceedings to foreclose this Mortgage nor the exercise of any other rights hereunder nor the recovery of any judgment by Mortgagee in any such proceedings shall prejudice, limit or preclude Mortgagee’s
right to commence or continue one or more foreclosure or other proceedings or obtain a judgment against any other collateral (either in or outside the state where the Real Estate is located) which secures the Obligations, and Mortgagor expressly
waives any objections to the commencement of, continuation of, or entry of a judgment in such other proceedings or exercise of any remedies in such proceedings based upon any action or judgment connected to this Mortgage, and Mortgagor also waives
any right to seek to dismiss, stay the execution of, remove, transfer or consolidate either such other proceedings or any action under this Mortgage on such basis. It is expressly understood and agreed that to the fullest extent permitted by law,
Mortgagee may, at its election, cause the sale of all collateral which is the subject of a single foreclosure action at either a single sale or at multiple sales conducted simultaneously and take such other measures as are appropriate in order to
effect the agreement of the parties to dispose of and administer all collateral securing the Obligations in the most economical and least time-consuming manner. 
 29. Successors and Assigns. All covenants of Mortgagor contained in this Mortgage are imposed solely and exclusively for the benefit of Mortgagee and its respective successors and assigns, and no
other persons or entities shall have standing to require compliance with such covenants or be deemed, under any circumstances, to be a beneficiary of such covenants. All such covenants of Mortgagor shall run with the land and bind Mortgagor, the
successors and assigns of Mortgagor (and each of them) and all subsequent owners, encumbrances and tenants of the Mortgaged Property, and shall inure to the benefit of Mortgagee and its successors and assigns. The word “Mortgagor”
shall be construed as if it read “Mortgagors” whenever the sense of this Mortgage so requires, and if there shall be more than one Mortgagor, the obligations of the Mortgagors shall be joint and several. 

30. No Waivers, etc. Any failure by Mortgagee to insist upon the strict performance by Mortgagor of any of the terms and provisions
of this Mortgage shall not be deemed to be a waiver of any of the terms and provisions hereof, and Mortgagee, notwithstanding any such failure, shall have the right thereafter to insist upon the strict performance by Mortgagor of any and all of the
terms and provisions of this Mortgage to be performed by Mortgagor. Mortgagee may release, regardless of consideration and without the necessity for any notice to or consent by the beneficiary of any subordinate mortgage or the holder of any
subordinate lien on the Mortgaged Property, any part of the security held for the obligations secured by this Mortgage without, as to the remainder of the security, in any way impairing or affecting the lien of this Mortgage or the priority of such
lien over any subordinate lien or mortgage. 

  
 15 

 31. GOVERNING LAW, ETC. THIS MORTGAGE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE IN WHICH THE REAL ESTATE IS LOCATED, EXCEPT THAT MORTGAGOR EXPRESSLY ACKNOWLEDGES THAT BY ITS TERMS THE CREDIT AGREEMENT SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF
PENNSYLVANIA, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAW, AND FOR PURPOSES OF CONSISTENCY, MORTGAGOR AGREES THAT IN ANY IN PERSONAM PROCEEDING RELATED TO THIS MORTGAGE THE RIGHTS OF THE PARTIES TO THIS MORTGAGE SHALL ALSO BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA GOVERNING CONTRACTS MADE AND TO BE PERFORMED IN THAT STATE, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAW. 

32. Waiver of Trial by Jury. Mortgagor and Mortgagee each hereby irrevocably and unconditionally waive trial by jury in any action,
claim, suit or proceeding relating to this Mortgage and for any counterclaim brought therein. Mortgagor hereby waives all rights to interpose any counterclaim in any suit brought by Mortgagee for foreclosure hereunder and all rights to have any such
suit consolidated with any separate suit, action or proceeding. Such waiver shall not be construed so as to prevent Mortgagor or Borrower from interposing a counterclaim against Mortgagee concerning the Obligations. 

33. Certain Definitions. Unless the context clearly indicates a contrary intent or unless otherwise specifically provided herein,
words used in this Mortgage shall be used interchangeably in singular or plural form and the word “Mortgagor” shall mean “each Mortgagor or any subsequent owner or owners of the Mortgaged Property or any part thereof or
interest therein,” the term “Mortgagee” shall mean “Mortgagee or any successor agent for the Lenders,” the word `person” shall include any individual, corporation, partnership, trust, unincorporated association,
government, governmental authority, or other entity, and the words “Mortgaged Property” shall include any portion of the Mortgaged Property or interest therein. Whenever the context may require, any pronouns used herein shall
include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural and vice versa. The captions in this Mortgage are for convenience of reference only and in no way limit or amplify
the provisions hereof. 
 34. Intercreditor Agreement. Notwithstanding anything herein to the contrary, the lien and
security interest granted to the Mortgagee pursuant to this Mortgage and the Other Documents and the exercise of any right or remedy by the Mortgagee hereunder and thereunder are subject to the provisions of the Intercreditor Agreement. In the event
of any conflict between the terms of the Intercreditor Agreement and this Mortgage with respect to lien priority or rights and remedies in connection with the Shared Collateral (as defined in the Intercreditor Agreement), the terms of the
Intercreditor Agreement shall govern.
