of 801 Cherry St, Suite 3700, Unit 19, Fort Worth, Texas 76102 (the “Mortgagor”), and JPMORGAN CHASEBANK, N.A., with offices and banking quarters at 2200 Ross Ave., 3rd Floor, Dallas, Texas 75201, as Global Administrative Agent
(“Mortgagee”) for its benefit and the benefit of the Canadian Administrative Agent, the other Secured Parties (as defined in each of the Credit Agreements) (collectively, the “Combined Secured Parties”). 

R E C I T A L S 
 A. The
Mortgagor, as borrower, JPMorgan Chase Bank, N.A., as global administrative agent (the “Global Administrative Agent”), and the various financial institutions party thereto as agents or lenders (the “U.S. Lenders”)
entered into that certain Amended and Restated Credit Agreement dated as of December 22, 2011 (as amended by Omnibus Amendment No. 1 dated as of May 23, 2012, Omnibus Amendment No. 2 dated as of August 6, 2012, Omnibus
Amendment No. 3 dated as of October 5, 2012, and Omnibus Amendment No. 4 dated as of April 30, 2013, and as further amended, supplemented or modified, the “U.S. Credit Agreement”)). 

B. The Mortgagor, as parent, Quicksilver Resources Canada, Inc., the Canadian borrower, the JPMorgan Chase Bank, N.A., Toronto Branch, as
Canadian administrative agent, the Global Administrative Agent, and the various financial institutions party thereto as agents or lenders (the “Canadian Lenders”) entered into that certain Amended and Restated Credit Agreement dated

 D. On December 22, 2011, Mortgagor, as borrower, and Mortgagee entered into the First

performance of the Secured Indebtedness (as defined under the U.S. Credit Agreement) and the Secured Indebtedness (as defined under the Canadian Credit Agreement) (each such Secured Indebtedness being collectively referred to as the
“Combined Secured Obligations”). 
 E. On the date hereof, the Mortgagor expects to enter into Permitted Second Lien Debt
(as defined in the U.S. Credit Agreement) that will be secured pursuant to a mortgage by a second priority lien on the property that secures the Mortgage and in order to comply with Section 8.13(f) of each Combined Credit Agreement and to

F. The Mortgagor and Mortgagee also desire to amend and supplement the Mortgage to add to Exhibit A thereto certain leases (including leases
in Hood County, Texas that were inadvertently omitted from the Mortgage), which are described on Exhibit A attached hereto (the “Additional Properties”). With respect to any Additional Properties located in Erath County, Texas, a
copy of the Mortgage is attached to the counterpart of this Amendment to be recorded in that county as Exhibit B. 
 G. The Mortgage was
duly recorded in the office designated for filing of a record of deed of trust in the jurisdictions and under the recording information for each set forth in Annex I hereto. 

NOW, THEREFORE, in view of the foregoing, Mortgagor and Mortgagee do hereby agree as follows:

and (c) the aggregate amount of the Senior Obligations may be increased, in each case, without notice to or consent by the Second Priority Representatives or the Second Priority Debt Parties and without affecting the provisions hereof (it being
understood, for avoidance of doubt, that any such increase is subject to the 2nd paragraph of the definition of Senior Obligations to the extent applicable). The Lien priorities provided for in Section 2.01 shall not be altered or otherwise affected
by any amendment, supplement or other modification, or any Refinancing, of either the Senior Obligations or the Second Priority Debt Obligations, or any portion thereof. As between the Company and the other Grantors and the Second Priority Debt
Parties or Senior Secured Parties, as the case may be, the foregoing provisions will not limit or otherwise affect the obligations of the Company and the Grantors contained in any Second Priority Debt Document or Senior Debt Document, as the case
may be, with respect to the incurrence of additional Senior Obligations or Second Priority Debt, as the case may be.

as provided in Section 2.01) or any of the Senior Debt Documents. 
 SECTION 2.04. No New Liens. The parties hereto agree that,
so long as the Discharge of Senior Obligations has not occurred, (a) none of the Grantors shall grant or permit any additional Liens on any asset or property of any Grantor to secure any Second Priority Debt Obligation unless it has granted, or
concurrently therewith grants, a Lien on such asset or property of such Grantor to secure the Senior Obligations; (b) subject to Section 2.06, none of the Grantors shall grant or permit any additional Liens on any asset or property of any
Grantor to secure any Senior Obligations unless it has granted, or concurrently therewith grants, a Lien on such asset or property of such Grantor to secure the Second Priority Debt Obligations (it being understood, for the avoidance of doubt, that
this clause (b) shall not apply to Senior Canadian Collateral); and (c) if any Second Priority Representative or any Second Priority Debt Party shall hold any Lien on any assets or property of any Grantor securing any Second Priority Debt
Obligations that are not also subject to the first-priority Liens securing all Senior Obligations under the Senior Collateral Documents, such Second Priority Representative or Second Priority Debt Party (i) shall notify the Senior
Representative promptly upon becoming aware thereof and, unless such Grantor shall promptly grant a similar Lien on such assets or property to the Senior Representative as security for the Senior Obligations, shall assign such Lien to the Senior
Representative as security for all Senior Obligations for the benefit of the Senior Secured Parties (but may retain a junior lien on such assets or property subject to the terms hereof) and (ii) until such assignment or such grant of a similar
Lien to the Senior Representative, shall be deemed to hold and have held such Lien for the benefit of the Senior Representative and the other Senior Secured Parties as security for the Senior Obligations. 

To the extent that the foregoing provisions are not complied with for any reason, without limiting any other rights and remedies available to
the Senior Representative and/or the Senior Secured Parties, the Second Priority Representative, on behalf of Second Priority Debt Parties, agrees that any amounts received by or distributed to any of them pursuant to or as a result of Liens granted
in contravention of this Section 2.04 shall be treated in the same manner as set forth in Section 4.02. 
 SECTION 2.05. Perfection
of Liens. Except for the limited agreements of the Senior Representative pursuant to Section 5.05 hereof, neither the Senior Representative nor the Senior Secured Parties shall be responsible for perfecting and maintaining the perfection of
Liens with respect to the Shared Collateral for the benefit of the Second Priority Representatives or the Second Priority Debt Parties. The provisions of this Agreement are intended solely to govern the respective Lien priorities as between the
Senior Secured Parties and the Second 

  
 13 

 
Priority Debt Parties and shall not impose on the Senior Representative, the Senior Secured Parties, the Second Priority Representatives, the Second Priority Debt Parties or any agent or trustee
therefor any obligations in respect of the disposition of Proceeds of any Shared Collateral which would conflict with prior perfected claims therein in favor of any other Person or any order or decree of any court or governmental authority or any
applicable law. 
 SECTION 2.06. Certain Cash Collateral. Notwithstanding anything in this Agreement or any other Senior Debt
Documents or Second Priority Debt Documents to the contrary, collateral consisting of cash and cash equivalents pledged to secure Senior Obligations consisting of reimbursement obligations in respect of Letters of Credit or otherwise held by the
Senior Representative pursuant to Section 2.08(j) of each of the Combined Credit Agreements as in effect on the date hereof (or any equivalent successor provision) shall be applied as specified in the U.S. Credit Agreement and will not
constitute Shared Collateral. 
 ARTICLE III 

Enforcement 

SECTION 3.01. Exercise of Remedies. 

(a) So long as the Discharge of Senior Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has been
commenced by or against the Company or any other Grantor, 
 (i) neither any Second Priority Representative nor any Second
Priority Debt Party will (A) exercise or seek to exercise any rights or remedies (including setoff or recoupment) with respect to any Shared Collateral in respect of any Second Priority Debt Obligations, or institute any action or proceeding
with respect to such rights or remedies (including any action of foreclosure); provided, that, subject to extension as a result of any Permitted Delay, the Designated Second Priority Representative may exercise any or all such rights (but not
rights the exercise of which is otherwise prohibited by this Agreement including ARTICLE VI) after a period (such period, as extended as a result of any Permitted Delay, the “Standstill Period”) of 180 consecutive days has elapsed
from the date of delivery of written notice from the Designated Second Priority Representative to the Senior Representative stating that (1) an Event of Default (as defined under the Second Priority Debt Documents) has occurred and is
continuing thereunder, (2) the Second Priority Debt Obligations are currently due and payable in full (whether as a result of acceleration thereof or otherwise) in accordance with the terms of the Second Priority Debt Documents, and
(3) the Designated Second Priority Representative intends to exercise its rights to take such actions, only so long as the Senior Representative or Senior Secured Parties are not then diligently pursuing their rights and remedies with respect
to all or a material portion of the Shared Collateral or diligently attempting to vacate any stay or prohibition against such exercise or the Company or any other Grantor is then a debtor under or with respect to (or otherwise subject to) any
Insolvency or Liquidation Proceeding (any such period while the Senior Representatives or Senior Secured Parties are diligently pursuing such rights and remedies or making any such attempt or any such Grantor is a debtor, a “Permitted
Delay”), (B) contest, protest or 

  
 14 

 
object to any foreclosure proceeding or action brought with respect to the Shared Collateral or any other Senior Collateral by the Senior Representative or any Senior Secured Party in respect of
the Senior Obligations, the exercise of any right by the Senior Representative or any Senior Secured Party (or any agent or sub-agent on their behalf) in respect of the Senior Obligations under any lockbox agreement, control agreement, landlord
waiver or bailee’s letter or similar agreement or arrangement to which the Senior Representative or any Senior Secured Party either is a party or may have rights as a third party beneficiary, or any other exercise by any such party of any
rights and remedies relating to the Shared Collateral under the Senior Debt Documents or otherwise in respect of the Senior Collateral or the Senior Obligations, (C) object to the forbearance by the Senior Secured Parties from bringing or
pursuing any foreclosure proceeding or action during the Standstill Period or any other exercise of any rights or remedies relating to the Shared Collateral in respect of Senior Obligations or (D) credit bid (it being understood, for the
avoidance of doubt, that a credit bid which includes a cash portion sufficient to cause a Discharge of Senior Obligations will not be precluded), and 

(ii) except as otherwise provided herein, the Senior Representative and the Senior Secured Parties shall have the exclusive
right to enforce rights, exercise remedies (including setoff, recoupment and the right to credit bid their debt) and, in that connection, to make determinations regarding the release, disposition or restrictions with respect to the Shared Collateral
without any consultation with or the consent of any Second Priority Representative or any Second Priority Debt Party; provided, however, that (A) in any Insolvency or Liquidation Proceeding commenced by or against the Company or
any other Grantor, any Second Priority Representative may file a claim, proof of claim, or statement of interest with respect to the Second Priority Debt Obligations under its Second Priority Debt Facility, (B) any Second Priority
Representative may take any action (not adverse to the prior Liens on the Shared Collateral securing the Senior Obligations or the rights of the Senior Representative or the Senior Secured Parties to exercise remedies in respect thereof) in order to
create, prove, perfect, preserve or protect (but not enforce) its rights in, and perfection and priority of its Lien on, the Shared Collateral, (C) any Second Priority Representative and the Second Priority Debt Parties may exercise their
rights and remedies as unsecured creditors, as provided in Section 5.04, (D) any Second Priority Representative may exercise the rights and remedies provided for in Article VI, (E) in any Insolvency or Liquidation Proceeding, any Second
Priority Debt Party may file any necessary or appropriate responsive or defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading made by any person objecting to or otherwise seeking the disallowance of the
claims or Liens of the Second Priority Debt Parties, including without limitation any claims secured by the Shared Collateral, if any, in each case in accordance with the terms of this Agreement, and (F) in any Insolvency or Liquidation
Proceeding, the Second Priority Debt Parties may vote on any plan of reorganization, but only to the extent consistent with the provisions hereof and, in respect of any such vote for a reorganization plan which constitutes a “cram-up”
under Section 1129(b) of the Bankruptcy Code on the Senior Secured Parties, to which the Senior Representative consents. In exercising rights and remedies with respect to the Senior Collateral, the Senior Representative and the Senior Secured
Parties may enforce the provisions of the Senior Debt Documents and exercise remedies thereunder, all in such 

  
 15 

 
order and in such manner as they may determine in the exercise of their sole discretion. Such exercise and enforcement shall include the rights of an agent appointed by them to sell or otherwise
dispose of Shared Collateral upon foreclosure, to incur expenses in connection with such sale or disposition and to exercise all the rights and remedies of a secured lender under the Uniform Commercial Code of any applicable jurisdiction and of a
secured creditor under Bankruptcy Laws of any applicable jurisdiction. 
 (b) Until the expiration of the Standstill Period and subject to
Section 4.02, each Second Priority Representative, on behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, agrees that it will not, in the context of its role as secured creditor, take or receive any Shared
Collateral or any Proceeds of Shared Collateral in connection with the exercise of any right or remedy (including setoff and recoupment) with respect to any Shared Collateral in respect of Second Priority Debt Obligations. Without limiting the
generality of the foregoing, unless and until the expiration of the Standstill Period has occurred, except as expressly provided in the proviso in clause (ii) of Section 3.01(a), the sole right of the Second Priority Representatives and the Second
Priority Debt Parties with respect to the Shared Collateral is to hold a Lien on the Shared Collateral in respect of Second Priority Debt Obligations pursuant to the Second Priority Debt 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 Senior Obligations has occurred. 
 (c) Subject to the proviso in
clause (ii) of Section 3.01(a), (i) each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, agrees that neither such Second Priority Representative nor any such
Second Priority Debt Party will take any action that would hinder any exercise of remedies undertaken by the Senior Representative or any Senior Secured Party with respect to the Shared Collateral under the Senior Debt Documents, including any sale,
lease, exchange, transfer or other disposition of the Shared Collateral, whether by foreclosure or otherwise, and (ii) each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority
Debt Facility, hereby waives any and all rights it or any such Second Priority Debt Party may have as a junior lien creditor or otherwise to object to the manner in which the Senior Representative or the Senior Secured Parties seek to enforce or
collect the Senior Obligations or the Liens granted on any of the Senior Collateral, regardless of whether any action or failure to act by or on behalf of the Senior Representative or any other Senior Secured Party is adverse to the interests of the
Second Priority Debt Parties. 
 (d) Each Second Priority Representative hereby acknowledges and agrees that no covenant, agreement or
restriction contained in any Second Priority Debt Document shall be deemed to restrict in any way the rights and remedies of the Senior Representative or the Senior Secured Parties with respect to the Senior Collateral as set forth in this Agreement
and the Senior Debt Documents. 
 (e) Until the expiration of the Standstill Period, the Senior Representative shall have the exclusive
right to exercise any right or remedy with respect to the Shared Collateral and shall have the exclusive right to determine and direct the time, method and place for exercising such right or remedy or conducting any proceeding with respect thereto.

  
 16 

 Following the Discharge of Senior Obligations, the Second Lien Agent shall have the exclusive
right to exercise any right or remedy with respect to the Collateral, and the Designated Second Priority Representative shall have the exclusive right to direct the time, method and place of exercising or conducting any proceeding for the exercise
of any right or remedy available to the Second Priority Debt Parties with respect to the Collateral, or of exercising or directing the exercise of any trust or power conferred on the Second Priority Representatives, or for the taking of any other
action authorized by the Second Priority Collateral Documents; provided, however, that nothing in this Section shall impair the right of any Second Priority Representative or other agent or trustee acting on behalf of the Second
Priority Debt Parties to take such actions with respect to the Second Priority Collateral after the Discharge of Senior Obligations as may be otherwise required or authorized pursuant to any intercreditor agreement governing the Second Priority Debt
Parties or the Second Priority Debt Obligations. 
 SECTION 3.02. Cooperation. Subject to the proviso in clause (ii) of Section
3.01(a), each Second Priority Representative, on behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, agrees that, unless and until the Discharge of Senior Obligations or the expiration of the Standstill
Period has occurred, it will not commence, or join with any Person (other than the Senior Secured Parties and the Senior Representative upon the request of the Senior Representative) in commencing, any enforcement, collection, execution, levy or
foreclosure action or proceeding with respect to any Lien held by it in the Shared Collateral under any of the Second Priority Debt Documents or otherwise in respect of the Second Priority Debt Obligations. 

SECTION 3.03. Actions upon Breach. Should any Second Priority Representative or any Second Priority Debt Party, contrary to this
Agreement, in any way take, attempt to take or threaten to take any action with respect to the Shared Collateral (including any attempt to realize upon or enforce any remedy with respect to this Agreement) or fail to take any action required by this
Agreement, the Senior Representative or other Senior Secured Party (in its or their own name or in the name of the Company or any other Grantor) may obtain relief against such Second Priority Representative or such Second Priority Debt Party by
injunction, specific performance or other appropriate equitable relief. Each Second Priority Representative, on behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, hereby (a) agrees that the Senior
Secured Parties’ damages from the actions of the Second Priority Representatives or any Second Priority Debt Party may at that time be difficult to ascertain and may be irreparable and waives any defense that the Company, any other Grantor or
the Senior Secured Parties cannot demonstrate damage or be made whole by the awarding of damages and (b) irrevocably waives any defense based on the adequacy of a remedy at law and any other defense that might be asserted to bar the remedy of
specific performance in any action that may be brought by the Senior Representative or any other Senior Secured Party. 
 ARTICLE IV 

Payments 

SECTION 4.01. Application of Proceeds. After an event of default under any Senior Debt Document has occurred and until such event
of default is cured or waived, so long as the Discharge of Senior Obligations has not occurred, the Shared Collateral or Proceeds 

  
 17 

 
thereof received in connection with the sale or other disposition of, or collection on, such Shared Collateral upon the exercise of remedies shall be applied by the Senior Representative to the
Senior Obligations in such order as specified in the relevant Senior Debt Documents until the Discharge of Senior Obligations has occurred. Upon the Discharge of Senior Obligations, the Senior Representative shall deliver promptly to the Designated
Second Priority Representative any Shared Collateral or Proceeds thereof held by it in the same form as received, with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct, to be applied by the Designated Second
Priority Representative to the Second Priority Debt Obligations in such order as specified in the relevant Second Priority Debt Documents. 

SECTION 4.02. Payments Over. Unless and until the Discharge of Senior Obligations has occurred, any Shared Collateral or Proceeds
thereof received by any Second Priority Representative or any Second Priority Debt Party in connection with the exercise of any right or remedy (including setoff or recoupment) relating to the Shared Collateral shall be segregated and held in trust
for the benefit of and promptly paid over to the Senior Representative for the benefit of the Senior Secured Parties in the same form as received, with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct. The
Senior Representative is hereby authorized to make any such endorsements as agent for each of the Second Priority Representatives or any such Second Priority Debt Party. This authorization is coupled with an interest and is irrevocable. 

ARTICLE V 
 Other Agreements

 SECTION 5.01. Releases. 

(a) Each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility,
agrees that, in the event of a sale, transfer or other disposition of any specified item of Shared Collateral (including all or substantially all of the equity interests of any subsidiary of the Company) in connection with (i) the exercise of
remedies in respect of Collateral or (ii) any sale, transfer or other disposition that is permitted under the Second Priority Debt Documents as in effect on the date hereof or subsequently permitted thereunder, the Liens granted to the Second
Priority Representatives and the Second Priority Debt Parties upon such Shared Collateral to secure Second Priority Debt Obligations shall terminate and be released, automatically and without any further action, concurrently with the termination and
release of all Liens granted upon such Shared Collateral to secure Senior Obligations. Upon delivery to a Second Priority Representative of an Officer’s Certificate stating that any such termination and release of Liens securing the Senior
Obligations has become effective (or shall become effective concurrently with such termination and release of the Liens granted to the Second Priority Debt Parties and the Second Priority Representatives) and any necessary or proper instruments of
termination or release prepared by the Company or any other Grantor, such Second Priority Representative will promptly execute, deliver or acknowledge, at the Company’s or the other Grantor’s sole cost and expense, such instruments to
evidence such termination and release of the Liens. Nothing in this Section 5.01(a) will be deemed to affect any agreement of a Second Priority Representative, for itself and on behalf of the Second Priority Debt Parties under its Second Priority
Debt Facility, to release the Liens on the Second Priority Collateral as set forth in the relevant Second Priority Debt Documents. 

  
 18 

 (b) Each Second Priority Representative, for itself and on behalf of each Second Priority Debt
Party under its Second Priority Debt Facility, hereby irrevocably constitutes and appoints the Senior Representative and any officer or agent of the Senior Representative, 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 such Second Priority Representative or such Second Priority Debt Party or in the Senior Representative’s own name, from time to time in the Senior Representative’s discretion,
for the purpose of carrying out the terms of Section 5.01(a), to take any and all appropriate action and to execute any and all documents and instruments that may be necessary or desirable to accomplish the purposes of Section 5.01(a), including any
termination statements, endorsements or other instruments of transfer or release. 
 (c) Unless and until the Discharge of Senior
Obligations has occurred, each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, hereby consents to the application, whether prior to or after an event of default
under any Senior Debt Document of Proceeds of the Senior Collateral to the repayment of Senior Obligations pursuant to the Senior Debt Documents, provided that nothing in this Section 5.01(c) shall be construed to prevent or impair the rights of the
Second Priority Representatives or the Second Priority Debt Parties to receive proceeds in connection with the Second Priority Debt Obligations not otherwise in contravention of this Agreement. 

(d) Notwithstanding anything to the contrary in any Second Priority Collateral Document, in the event the terms of a Senior Collateral
Document and a Second Priority Collateral Document each require any Grantor (i) to make payment in respect of any item of Shared Collateral to, (ii) to deliver or afford control over (to the extent only one party can have control of such
Shared Collateral) any item of Shared Collateral to, or deposit any item of Shared Collateral with, (iii) to register ownership of any item of Shared Collateral in the name of or make an assignment of ownership of any Shared Collateral or the
rights thereunder, and (iv) to hold any item of Shared Collateral in trust for (to the extent such item of Shared Collateral cannot be held in trust for multiple parties under applicable law), in favor of, in any case, both the Senior
Representative and any Second Priority Representative or Second Priority Debt Party, such Grantor may, until the Discharge of Senior Obligations has occurred, comply with such requirement under the Second Priority Collateral Document as it relates
to such Shared Collateral by taking any of the actions set forth above only with respect to, or in favor of, the Senior Representative. 

SECTION 5.02. Insurance and Condemnation Awards. Unless and until the Discharge of Senior Obligations has occurred, the Senior
Representative and the Senior Secured Parties shall have the sole and exclusive right, subject to the rights of the Grantors under the Senior Debt Documents, (a) to adjust settlement for any insurance policy covering the Shared Collateral in
the event of any loss thereunder and (b) to approve any award granted in any condemnation or similar proceeding affecting the Shared Collateral. Unless and until the Discharge of Senior Obligations has occurred, all proceeds of any such policy
and any such award, if in respect of the Shared Collateral, shall be paid (i) first, prior to the occurrence of the Discharge of Senior Obligations, to the Senior Representative for the benefit of Senior Secured

  
 19 

 
Parties pursuant to the terms of the Senior Debt Documents, (ii) second, after the occurrence of the Discharge of Senior Obligations, to the Second Lien Agent for the benefit of the Second
Priority Debt Parties pursuant to the terms of the applicable Second Priority Debt Documents and (iii) third, if no Second Priority Debt Obligations are outstanding, to the owner of the subject property, such other Person as may be entitled
thereto or as a court of competent jurisdiction may otherwise direct. If any Second Priority Representative or any Second Priority Debt Party 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 Senior Representative in accordance with the terms of Section 4.02. 

SECTION 5.03. Amendments to Second Priority Collateral Documents. 

(a) No Second Priority Collateral Document may be amended, supplemented or otherwise modified or entered into to the extent such amendment,
supplement or modification, or the terms of any new Second Priority Collateral Document, would be prohibited by or inconsistent with any of the terms of this Agreement. The Company agrees to deliver to the Senior Representative copies of
(i) any amendments, supplements or other modifications to the Second Priority Collateral Documents and (ii) any new Second Priority Collateral Documents promptly after effectiveness thereof. Each Second Priority Representative, for itself
and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, agrees that each Second Priority Collateral Document under its Second Priority Debt Facility shall include the following language (or language to similar
effect reasonably approved by the Senior Representative): 
 “Notwithstanding anything herein to the contrary, (a) the liens and
security interests granted to the [Insert Second Priority Representative] pursuant to this Agreement are expressly subject and subordinate to the liens and security interests granted in favor of the Senior Secured Parties (as defined in the
Intercreditor Agreement referred to below), including liens and security interests granted to (i) JPMorgan Chase Bank, N.A., as global administrative agent, pursuant to or in connection with the Amended and Restated Credit Agreement, dated as
of December 22, 2011 (as amended, restated, supplemented or otherwise modified from time to time), among the Company, the banks, financial institutions and other lending institutions from time to time parties as lenders thereto and JPMorgan
Chase Bank, N.A., as global administrative agent, and (ii) JPMorgan Chase Bank, N.A., Toronto Branch, as administrative agent, pursuant to or in connection with the Amended and Restated Credit Agreement, dated as of December 22, 2011 (as
amended, restated, supplemented or otherwise modified from time to time), among the Company, Quicksilver Resources, Canada, Inc., as borrower, the banks, financial institutions and other lending institutions from time to time parties as lenders
thereto and JPMorgan Chase Bank, N.A., as global administrative agent, and JPMorgan Chase Bank, N.A., Toronto Branch, as administrative agent, and (b) the exercise of any right or remedy by [Insert Second Priority Representative] hereunder is
subject to the limitations and provisions of the Intercreditor Agreement dated as of June 21, 2013 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”), among JPMorgan
Chase Bank, N.A., as Senior Representative, 

  
 20 

 
Credit Suisse AG, Cayman Islands Branch, as Initial Second Priority Representative and as Administrative Agent, The Bank of New York Mellon Trust Company N.A., as Trustee, the Company and its
subsidiaries and affiliated entities party thereto. In the event of any conflict between the terms of the Intercreditor Agreement and the terms of this Agreement, the terms of the Intercreditor Agreement shall govern.” 

(b) In the event that the Senior Representative or the Senior Secured Parties enter into any amendment, waiver or consent in respect of any of
the Senior Collateral Documents for the purpose of adding to or deleting from, or waiving or consenting to any departures from any provisions of, any Senior Collateral Document or changing in any manner the rights of the Senior Representative, the
Senior Secured Parties, the Company or any other Grantor thereunder (including the release of any Liens in Senior Collateral), then such amendment, waiver or consent shall apply automatically to any comparable provision of each comparable Second
Priority Collateral Document without the consent of any Second Priority Representative or any Second Priority Debt Party and without any action by any Second Priority Representative, the Company or any other Grantor; provided, however,
that (i) no such amendment, waiver or consent shall have the effect of (A) removing assets subject to the Lien of the Second Priority Collateral Documents, except to the extent that a release of such Lien is permitted by Section 5.01 of
this Agreement and provided that there is a corresponding release of the Lien securing the Senior Obligations, (B) imposing duties on the Designated Second Priority Representative without its consent or (C) altering the terms of the Second
Priority Debt Documents to permit other Liens on the Collateral not permitted under the terms of the Second Priority Debt Documents as in effect on the date hereof or Article VI hereof and (ii) written notice of such amendment, waiver or
consent shall have been given to each Second Priority Representative within ten (10) Business Days after the effectiveness of such amendment, waiver or consent. 

SECTION 5.04. Rights as Unsecured Creditors. Notwithstanding anything to the contrary in this Agreement, during an Event of
Default (as defined under the Second Priority Debt Documents), the Second Priority Representatives and the Second Priority Debt Parties may exercise rights and remedies as unsecured creditors against the Company and any other Grantor in accordance
with the terms of the Second Priority Debt Documents and applicable law so long as such rights and remedies do not violate any express provision of this Agreement. Nothing in this Agreement shall prohibit the receipt by any Second Priority
Representative or any Second Priority Debt Party of the required payments of principal, premium, interest, fees and other amounts due under the Second Priority Debt Documents so long as such receipt is not the direct or indirect result of the
exercise by a Second Priority Representative or any Second Priority Debt Party of rights or remedies as a secured creditor in respect of Shared Collateral. In the event any Second Priority Representative or any Second Priority Debt Party becomes a
judgment lien creditor in respect of Shared Collateral as a result of its enforcement of its rights as an unsecured creditor in respect of Second Priority Debt Obligations, such judgment lien shall be subordinated to the Liens securing Senior
Obligations on the same basis as the other Liens securing the Second Priority Debt Obligations are so subordinated to such Liens securing Senior Obligations under this Agreement. Nothing in this Agreement shall impair or otherwise adversely affect
any rights or remedies the Senior Representative or the Senior Secured Parties may have with respect to the Senior Collateral. 

  
 21 

 SECTION 5.05. Gratuitous Bailee for Perfection. 

(a) The Senior Representative acknowledges and agrees that if it shall at any time hold a Lien securing any Senior Obligations on any Shared
Collateral that can be perfected by the possession or control of such Shared Collateral or of any account in which such Shared Collateral is held, and if such Shared Collateral or any such account is in fact in the possession or under the control of
the Senior Representative, or of agents or bailees of such Person (such Shared Collateral being referred to herein as the “Pledged or Controlled Collateral”), or if it shall any time obtain any landlord waiver or bailee’s
letter or any similar agreement or arrangement granting it rights or access to Shared Collateral, the Senior Representative shall also hold such Pledged or Controlled Collateral, or take such actions with respect to such landlord waiver,
bailee’s letter or similar agreement or arrangement, as sub-agent or gratuitous bailee for the relevant Second Priority Representatives, in each case solely for the purpose of perfecting the Liens granted under the relevant Second Priority
Collateral Documents and subject to the terms and conditions of this Section 5.05. 
 (b) The rights of the Second Priority Representatives
and the Second Priority Debt Parties with respect to the Pledged or Controlled Collateral shall at all times be subject to the terms of this Agreement. 

(c) The Senior Representative and the Senior Secured Parties shall have no obligation whatsoever to the Second Priority Representatives or any
Second Priority Debt Party to assure that any of the Pledged or Controlled Collateral is genuine or owned by the Grantors or to protect or preserve rights or benefits of any Person or any rights pertaining to the Shared Collateral, except as
expressly set forth in this Section 5.05. The duties or responsibilities of the Senior Representative under this Section 5.05 shall be limited solely to holding or controlling the Shared Collateral and the related Liens referred to in paragraphs (a)
and (b) of this Section 5.05 as sub-agent and gratuitous bailee for the relevant Second Priority Representative for purposes of perfecting the Lien held by such Second Priority Representative. 

(d) The Senior Representative shall not have by reason of the Second Priority Collateral Documents or this Agreement, or any other document, a
fiduciary relationship in respect of any Second Priority Representative or any Second Priority Debt Party, and each, Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility,
hereby waives and releases the Senior Representative and Senior Secured Parties from all claims and liabilities arising pursuant to the Senior Representative’s roles under this Section 5.05 as sub-agent and gratuitous bailee with respect to the
Shared Collateral. 
 (e) Following the Discharge of Senior Obligations, the Senior Representative shall, at the Grantors’ sole cost
and expense, upon request (i) (A) deliver to the Designated Second Priority Representative, to the extent that it is legally permitted to do so, all Shared Collateral, including all Proceeds thereof, held or controlled by the Senior
Representative or any of its agents or bailees, including the transfer of possession and control, as applicable, of the Pledged or Controlled Collateral, together with any necessary endorsements and notices to depositary banks, securities
intermediaries and commodities intermediaries, and assign its rights under any landlord waiver or bailee’s letter or any similar agreement or arrangement granting it 

  
 22 

 
rights or access to Shared Collateral, or (B) direct and deliver such Shared Collateral as a court of competent jurisdiction may otherwise direct, (ii) notify any applicable insurance
carrier that it is no longer entitled to be a loss payee or additional insured under the insurance policies of any Grantor issued by such insurance carrier and (iii) notify any governmental authority involved in any condemnation or similar
proceeding involving any Grantor that the Designated Second Priority Representative is entitled to approve any awards granted in such proceeding. The Company and the other Grantors shall take such further action as is required to effectuate the
transfer contemplated hereby and shall indemnify the Senior Representative for loss or damage suffered by the Senior Representative as a result of such transfer, except for loss or damage suffered by any such Person as a result of its own willful
misconduct, gross negligence or bad faith. The Senior Representative has no obligations to follow instructions from any Second Priority Representative or any other Second Priority Debt Party in contravention of this Agreement. 

(f) Neither the Senior Representative nor any of the other Senior Secured Parties shall be required to marshal any present or future
collateral security for any obligations of the Company or any Subsidiary to the Senior Representative or any Senior Secured Party under the Senior Debt Documents or any assurance of payment in respect thereof, or to resort to such collateral
security or other assurances of payment in any particular order, and all of their rights in respect of such collateral security or any assurance of payment in respect thereof shall be cumulative and in addition to all other rights, however existing
or arising. 
 SECTION 5.06. When Discharge of Senior Obligations Deemed To Not Have Occurred. If, at any time after the
Discharge of Senior Obligations has occurred, the Company or any Subsidiary incurs any Senior Obligations (other than in respect of the payment of indemnities surviving the Discharge of Senior Obligations), then such Discharge of Senior Obligations
shall automatically be deemed not to have occurred for all purposes of this Agreement (other than with respect to any actions taken prior to the date of such designation as a result of the occurrence of such first Discharge of Senior Obligations)
and the applicable agreement governing such Senior Obligations shall automatically be treated as a Senior Debt Document for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of Shared Collateral set
forth herein and the agent, representative or trustee for the holders of such Senior Obligations shall be the Senior Representative for all purposes of this Agreement. Upon receipt of notice of such incurrence (including the identity of the new
Senior Representative), each Second Priority Representative (including the Designated Second Priority Representative) shall promptly upon request (a) enter into such documents and agreements (at the expense of the Company), including amendments
or supplements to this Agreement, as the Company or such new Senior Representative shall reasonably request in writing in order to provide the new Senior Representative the rights of the Senior Representative contemplated hereby, (b) deliver to
the Senior Representative, to the extent that it is legally permitted to do so, all Shared Collateral, including all Proceeds thereof, held or controlled by such Second Priority Representative or any of its agents or bailees, including the transfer
of possession and control, as applicable, of the Pledged or Controlled Collateral, together with any necessary endorsements and notices to depositary banks, securities intermediaries and commodities intermediaries, and agree to amendments to any
landlord waiver or bailee’s letter or any similar agreement or arrangement granting it rights or access to Shared Collateral, (c) notify any applicable insurance carrier that it is no longer entitled to be a sole loss payee or additional
insured under the 

  
 23 

 
insurance policies of any Grantor issued by such insurance carrier and (d) notify any governmental authority involved in any condemnation or similar proceeding involving a Grantor that the
new Senior Representative is entitled to approve any awards granted in such proceeding. 
 SECTION 5.07. Option to Repurchase.

 (a) Without prejudice to the enforcement of the Senior Secured Parties’ remedies, the Senior Secured Parties agree at any time
following an acceleration of the Senior Obligations in accordance with the terms of the U.S. Credit Agreement or the commencement of an Insolvency or Liquidation Proceeding, the Senior Secured Parties will offer the Second Priority Debt Parties the
option to purchase (the “Purchase”) at par/face amount the entire aggregate amount of outstanding Senior Obligations (which includes principal, interest, fees, breakage costs, attorneys’ fees and expenses, and, in the case of
any Swap Agreements, on a per Secured Swap Provider basis, the positive amount that is payable by the Company or relevant Guarantor thereunder reflecting any unpaid amount then due or amount owing in connection with the termination (or early
termination) on or prior to the date of the Purchase after giving effect to offset and netting arrangements in respect of such Secured Swap Provider, but which excludes any rights of the Senior Secured Parties with respect to indemnification and
other contingent obligations of the Company and Guarantors under the Senior Debt Documents that are expressly stated to survive the termination of the Senior Debt Documents). For avoidance of doubt, any Senior Obligations which are not purchased
will continue to constitute Senior Obligations hereunder and shall be secured in the same manner and subject to the same protections hereunder as existed immediately prior to the Purchase. The Purchase shall be made without warranty or
representation or recourse, on a pro rata basis across Senior Secured Parties. 
 (b) In connection with the exercise of such option, the
purchasing Second Priority Debt Parties shall furnish cash collateral to any relevant Senior Secured Party as it reasonably deems necessary to secure any such Senior Secured Party’s outstanding Letters of Credit or Canadian Letters of Credit
(not to exceed 105% of the face amount of the aggregate undrawn face amount of such letters of credit). 
 (c) The Second Priority Debt
Parties shall irrevocably accept or reject such offer within ten (10) Business Days of the receipt thereof and the parties shall endeavor to close promptly thereafter, but not later than thirty (30) Business Days after receipt of such
offer. If the Second Priority Debt Parties accept such offer, it shall be exercised pursuant to documentation mutually acceptable to the Senior Representative and the Second Priority Representative. If the Second Priority Debt Parties reject such
offer (or do not so irrevocably accept such offer within the required timeframe), the Senior Secured Parties shall have no further obligations pursuant to this Section 5.07 and may take any further actions in their sole discretion in accordance with
the Senior Debt Documents and this Agreement. 
 SECTION 5.08. Designated Senior Indebtedness. Notwithstanding any indenture or
other documentation for the Existing Subordinate Notes or other unsecured senior subordinated Debt incurred by the Company and its Subsidiaries which is permitted by the Senior Debt Documents (such indenture or other documentation, the
“Senior Subordinated Debt Documents”), each of the Second Priority Representative, for itself and on behalf of each Second Priority Debt Parties, and the Company agrees that, until the occurrence of the Discharge of

  
 24 

 
Senior Obligations, the Second Priority Representative shall not exercise any rights as a Representative (as defined in the Senior Subordinated Debt Documents) or any similar term of the holders
of “Designated Senior Indebtedness” or any similar term under the Senior Subordinated Debt Document that arise solely by virtue of Debt evidenced by the Second Priority Debt Obligations being designated “Designated Senior
Indebtedness” (or any similar term) under the Senior Subordinated Debt Document. The foregoing shall not prejudice the Senior Secured Parties’ or the Second Priority Debt Parties’ exercise of rights as holders of “Senior
Indebtedness” or any similar term under the Senior Subordinated Debt Documents. 
 ARTICLE VI 

Insolvency or Liquidation Proceedings. 

SECTION 6.01. Financing Issues. Until the Discharge of Senior Obligations has occurred, if the Company or any other Grantor shall
be subject to any Insolvency or Liquidation Proceeding and the Senior Representative or any Senior Secured Party shall desire to consent (or not object) to the sale, use or lease of cash collateral or to consent (or not object) to the Company’s
or any other Grantor’s obtaining financing under Section 363 or Section 364 of Title 11 of the United States Code or any similar provision of any other Bankruptcy Law (“DIP Financing”), then each Second Priority
Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, agrees that (except to the extent permitted by this Section 6.01 and so long as such cash collateral or DIP Financing is in an
amount that does not exceed the greater of (A) $70,000,000 and (B) the sum of (1) the aggregate principal amount of Loans and Canadian Loans and drawn Letters of Credit and Canadian Letters of Credit and the face amount of undrawn
Letters of Credit and Canadian Letters of Credit under the Combined Credit Agreements replaced or refinanced by any such DIP Financing and (2) 20% of the aggregate principal amount of Loans and Canadian Loans and drawn Letters of Credit and
Canadian Letters of Credit and the face amount of undrawn Letters of Credit and Canadian Letters of Credit outstanding under the Combined Credit Agreements on the date of the commencement of such Insolvency or Liquidation Proceeding (the
“DIP Cap”)) it will raise no: (a) objection to and will not otherwise contest such sale, use or lease of such cash collateral or such DIP Financing and, except to the extent permitted by the proviso in clause (ii) of Section
3.01(a), this Section 6.01, and Section 6.03, will not request adequate protection or any other relief in connection therewith and, to the extent the Liens securing any Senior Obligations are subordinated or pari passu with such DIP
Financing, will subordinate (and will be deemed hereunder to have subordinated) its Liens in the Shared Collateral to (x) such DIP Financing (and all obligations relating thereto) on the same basis as the Liens securing the Second Priority Debt
Obligations are so subordinated to Liens securing Senior Obligations under this Agreement, (y) any adequate protection Liens provided to the Senior Secured Parties, and (z) to any “carve-out” for professional and United
States Trustee fees agreed to by the Senior Representative; (b) objection to (and will not otherwise contest) any motion for relief from the automatic stay or from any injunction against foreclosure or enforcement in respect of Senior
Obligations and the Shared Collateral made by the Senior Representative or any other Senior Secured Party; (c) objection to (and will not otherwise contest) any lawful exercise by any Senior Secured Party of the right to credit bid Senior
Obligations at any sale in foreclosure of Senior Collateral or to exercise any rights under Section 1111(b) of Title 11 of the United States Code with respect to the Shared Collateral; (d) objection to (and will not otherwise contest) any
other 

  
 25 

 
request for judicial relief made in any court by any Senior Secured Party relating to the lawful enforcement of any Lien on Senior Collateral; or (e) objection to (and will not otherwise
contest or oppose) any order relating to a sale or other disposition of any of the Shared Collateral for which the Senior Representative has consented that provides, to the extent such sale or other disposition is to be free and clear of Liens,
(i) that the Liens securing the Senior Obligations and the Second Priority Debt Obligations will attach to the Proceeds of the sale on the same basis of priority as the Liens on the Shared Collateral securing the Senior Obligations rank to the
Liens on the Shared Collateral securing the Second Priority Debt Obligations pursuant to this Agreement, (ii) that net Proceeds of such sale shall be applied to reduce the Senior Obligations, and (iii) Second Priority Debt Parties will not
have been deemed to have waived the right to bid in cash in connection with the sale; notwithstanding the foregoing, the Second Priority Debt Parties may assert any objection to a sale or disposition of any Shared Collateral that is consistent with
the respective rights and obligations of the Senior Secured Parties and the Second Priority Debt Parties under this Agreement (without limiting the foregoing, Second Priority Debt Parties may not raise any objections based on rights afforded by
Sections 363(e), (f) and (k) of the Bankruptcy Code to secured creditors or any comparable provision of any other Bankruptcy Law). Each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its
Second Priority Debt Facility, agrees that notice from the Company received two (2) Business Days prior to the entry of an order approving such usage of cash or other collateral or approving such DIP Financing shall be adequate notice. 

SECTION 6.02. Relief from the Automatic Stay. Until the Discharge of Senior Obligations has occurred, each Second Priority
Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, agrees that none of them shall seek relief from the automatic stay or any other stay in any Insolvency or Liquidation Proceeding or
take any action in derogation thereof, in each case in respect of any Shared Collateral, without the prior written consent of the Senior Representative. 

SECTION 6.03. Adequate Protection. Each Second Priority Representative, for itself and on behalf of each Second Priority Debt
Party under its Second Priority Debt Facility, agrees that none of them shall (a) object, contest or support any other Person objecting to or contesting (i) any request by the Senior Representative or any Senior Secured Parties for
adequate protection, (ii) any objection by the Senior Representative or any Senior Secured Parties to any motion, relief, action or proceeding based on the Senior Representative’s or Senior Secured Party’s claiming a lack of adequate
protection or (iii) the payment of interest, fees, expenses or other amounts of the Senior Representative or any other Senior Secured Party under Section 506(b) of Title 11 of the United States Code or any similar provision of any other
Bankruptcy Law or (b) assert or support any claim for costs or expenses of preserving or disposing of any Collateral under Section 506(c) of Title 11 of the United States Code or any similar provision of any other Bankruptcy Law.
Notwithstanding anything contained in this Section 6.03 or in Section 6.01, in any Insolvency or Liquidation Proceeding, (1) if the Senior Secured Parties (or any subset thereof) are granted adequate protection in the form of additional
collateral or superpriority claims in connection with any DIP Financing or use of cash collateral under Section 363 or 364 of Title 11 of the United States Code or any similar provision of any other Bankruptcy Law, then each Second Priority
Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, may seek or request adequate protection in the form of a replacement Lien on such additional collateral or superpriority claim,

  
 26 

 
which Lien or superpriority claim is subordinated to the Liens securing all Senior Obligations and such DIP Financing (and all obligations relating thereto) on the same basis as the other Liens
securing the Second Priority Debt Obligations are so subordinated to the Liens securing Senior Obligations under this Agreement and (2) in the event any Second Priority Representatives, for themselves and on behalf of the Second Priority Debt
Parties under their Second Priority Debt Facilities, seek or request adequate protection and such adequate protection is granted in the form of additional collateral or superpriority claims (in each instance, to the extent such grant is otherwise
permissible under the terms and conditions of this Agreement), then such Second Priority Representatives, for themselves and on behalf of each Second Priority Debt Party under their Second Priority Debt Facilities, agree that the Senior
Representative shall also be granted (as applicable) a senior superpriority claim or senior Lien on such additional collateral as security for the Senior Obligations, and that any Lien on such additional collateral securing the Second Priority Debt
Obligations or superpriority claim granted to the Second Priority Debt Parties shall be subordinated to the Liens on such collateral securing the Senior Obligations and any such DIP Financing (and all obligations relating thereto) and any other
Liens granted to the Senior Secured Parties, or the superpriority claim granted to the Senior Secured Parties, as adequate protection on the same basis as the other Liens securing the Second Priority Debt Obligations are so subordinated to such
Liens securing Senior Obligations under this Agreement. Notwithstanding anything contained in this Section 6.03 or in Section 6.01, in any Insolvency or Liquidation Proceeding, to the extent that the Senior Secured Parties are granted adequate
protection in the form of payments in the amount of current incurred fees and expenses and/or other cash payments, or otherwise with the consent of the Senior Representative, then the Designated Second Priority Representative and the Second Priority
Debt Parties shall not be prohibited from seeking adequate protection in the form of payments in the amount of current incurred fees and expenses and/or other cash payments (as applicable), subject to the right of the Senior Secured Parties to
object to the reasonableness of the amounts of fees and expenses or other cash payments so sought by the Second Priority Debt Parties. In addition, to the extent the Senior Secured Parties are awarded or otherwise granted an allowed claim in any
Insolvency or Liquidation Proceeding with respect to post-petition interest, nothing herein shall prevent the Second Priority Debt Parties from seeking or otherwise asserting a claim for post-petition interest to the extent of the value of the Lien
of the Second Priority Debt Parties on the Shared Collateral (after taking into account the Senior Obligations). 
 SECTION 6.04.
Preference Issues. If any Senior Secured Party is required in any Insolvency or Liquidation Proceeding or otherwise to disgorge, turn over or otherwise pay any amount to the estate of the Company or any other Grantor (or any trustee, receiver
or similar Person therefor), because the payment of such amount was declared to be fraudulent or preferential in any respect or for any other reason, any amount (a “Recovery”), whether received as proceeds of security, enforcement
of any right of setoff or otherwise, then the Senior Obligations shall be reinstated to the extent of such Recovery and deemed to be outstanding as if such payment had not occurred and the Senior Secured Parties shall be entitled to the benefits of
this Agreement until a Discharge of Senior Obligations with respect to all such recovered amounts. If this Agreement shall have been terminated prior to such 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. Each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt
Facility, hereby agrees that none of them shall be entitled to benefit from any 

  
 27 

 
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. 

SECTION 6.05. Separate Grants of Security and Separate Classifications. Each Second Priority Representative, for itself and on
behalf of each Second Priority Debt Party under its Second Priority Debt Facility, acknowledges and agrees that (a) the grants of Liens pursuant to the Senior Collateral Documents and the Second Priority Collateral Documents constitute separate
and distinct grants of Liens and (b) because of, among other things, their differing rights in the Shared Collateral, the Second Priority Debt Obligations are fundamentally different from the Senior Obligations 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 any claims of the Senior Secured
Parties and the Second Priority Debt Parties in respect of the Shared Collateral constitute a single class of claims (rather than separate classes of senior and junior secured claims), then each Second Priority Representative, for itself and on
behalf of each Second Priority Debt Party under its Second Priority Debt Facility, hereby acknowledges and agrees 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 Shared Collateral (with the effect being that, to the extent that the aggregate value of the Shared Collateral is sufficient (for this purpose ignoring all claims held by the Second Priority Debt Parties), the Senior Secured Parties
shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of post-petition interest (whether or not allowed or allowable) before any
distribution is made from the Shared Collateral in respect of the Second Priority Debt Obligations, with each Second Priority Representative, for itself and on behalf of each Second Priority Debt Party under its Second Priority Debt Facility, hereby
acknowledging and agreeing to turn over to the Senior Representative amounts otherwise received or receivable by them from the Shared Collateral 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 Second Priority Debt Parties. 
 SECTION 6.06. No Waivers of Rights of Senior Secured
Parties. Nothing contained herein shall, except as expressly provided herein, prohibit or in any way limit the Senior Representative or any other Senior Secured Party from objecting in any Insolvency or Liquidation Proceeding or otherwise to any
action taken by any Second Priority Debt Party, including the seeking by any Second Priority Debt Party of adequate protection or the asserting by any Second Priority Debt Party of any of its rights and remedies under the Second Priority Debt
Documents or otherwise. 
 SECTION 6.07. Application. This Agreement, which the parties hereto expressly acknowledge is a
“subordination agreement” under Section 510(a) of Title 11 of the United States Code or any similar provision of any other Bankruptcy Law, shall be effective before, during and after the commencement of any Insolvency or
Liquidation Proceeding. The relative rights as to the Shared Collateral and Proceeds thereof shall continue after the commencement of any Insolvency or Liquidation Proceeding on the same basis as prior to the

  
 28 

 
date of the petition therefor, subject to any court order approving the financing of, or use of cash collateral by, any Grantor. All references herein to any Grantor shall include such Grantor as
a debtor-in-possession and any receiver or trustee for such Grantor. 
 SECTION 6.08. Other Matters. To the extent that any
Second Priority Representative or any Second Priority Debt Party has or acquires rights under Section 363 or Section 364 of Title 11 of the United States Code or any similar provision of any other Bankruptcy Law with respect to any of the
Shared Collateral, such Second Priority Representative, on behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, agrees not to assert any such rights without the prior written consent of the Senior
Representative, provided that if requested by the Senior Representative, such Second Priority Representative shall timely exercise such rights in the manner requested by the Senior Representative, including any rights to payments in respect of such
rights. 
 SECTION 6.09. 506(c) Claims. Until the Discharge of Senior Obligations has occurred, each Second Priority
Representative, on behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, agrees that it will not assert or enforce any claim under Section 506(c) of Title 11 of the United States Code or any similar
provision of any other Bankruptcy Law senior to or on a parity with the Liens securing the Senior Obligations for costs or expenses of preserving or disposing of any Shared Collateral. 

SECTION 6.10. Reorganization Securities. If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized
debtor secured by Liens upon any property of the reorganized debtor are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of both the Senior Obligations and the Second Priority Debt Obligations,
then, to the extent the debt obligations distributed on account of the Senior Obligations and on account of the Second Priority Debt Obligations are secured by Liens upon the same assets or property, the provisions of this Agreement will survive the
distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations. 

ARTICLE VII 

Reliance; Etc. 

SECTION 7.01. Reliance. The consent by the Senior Secured Parties to the execution and delivery of the Second Priority Debt
Documents to which the Senior Secured Parties have consented and all loans and other extensions of credit made or deemed made on and after the date hereof by the Senior Secured Parties to the Company or any Subsidiary shall be deemed to have been
given and made in reliance upon this Agreement. Each Second Priority Representative (acting at the direction of the Second Priority Debt Parties such Second Priority Representative represents), on behalf of itself and each Second Priority Debt Party
under its Second Priority Debt Facility, acknowledges that it and such Second Priority Debt Parties have, independently and without reliance on the Senior Representative or other Senior Secured Party, and based on documents and information deemed by
them appropriate, made their own credit analysis and decision to enter into the Second Priority Debt Documents to which they are party or by which they are bound, this Agreement and the transactions contemplated hereby and thereby, and they will
continue to make their own credit decisions in taking or not taking any action under the Second Priority Debt Documents or this Agreement. 

  
 29 

 SECTION 7.02. No Warranties or Liability. Each Second Priority Representative, on
behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, acknowledges and agrees that neither the Senior Representative nor any other Senior Secured Party has made any express or implied representation or
warranty, including with respect to the execution, validity, legality, completeness, collectability or enforceability of any of the Senior Debt Documents, the ownership of any Shared Collateral or the perfection or priority of any Liens thereon. The
Senior Secured Parties will be entitled to manage and supervise their respective loans and extensions of credit under the Senior Debt Documents in accordance with law and as they may otherwise, in their sole discretion, deem appropriate, and the
Senior Secured Parties may manage their loans and extensions of credit without regard to any rights or interests that the Second Priority Representatives and the Second Priority Debt Parties have in the Shared Collateral or otherwise, except as
otherwise provided in this Agreement. Neither the Senior Representative nor any other Senior Secured Party shall have any duty to any Second Priority Representative or Second Priority Debt Party to act or refrain from acting in a manner that allows,
or results in, the occurrence or continuance of an event of default or default under any agreement with the Company or any Subsidiary (including the Second Priority Debt Documents), regardless of any knowledge thereof that they may have or be
charged with. Except as expressly set forth in this Agreement, the Senior Representative, the Senior Secured Parties, the Second Priority Representatives and the Second Priority Debt Parties have not otherwise made to each other, nor do they hereby
make to each other, any warranties, express or implied, nor do they assume any liability to each other with respect to (a) the enforceability, validity, value or collectability of any of the Senior Obligations, the Second Priority Debt
Obligations or any guarantee or security which may have been granted to any of them in connection therewith, (b) any Grantor’s title to or right to transfer any of the Shared Collateral or (c) any other matter except as expressly set
forth in this Agreement. 
 SECTION 7.03. Obligations Unconditional. All rights, interests, agreements and obligations of the
Senior Representative, the Senior Secured Parties, the Second Priority Representatives and the Second Priority Debt Parties hereunder shall remain in full force and effect irrespective of: 

(a) any lack of validity or enforceability of any Senior Debt Document or any Second Priority Debt Document; 

(b) any change in the time, manner or place of payment of, or in any other terms of, all or any of the Senior Obligations or Second Priority
Debt Obligations, or any amendment or waiver or other modification, including any increase in the amount thereof, whether by course of conduct or otherwise, of the terms of each of the Combined Credit Agreements or any other Senior Debt Document or
of the terms of any Second Priority Debt Document; 
 (c) any exchange of any security interest in any Shared Collateral or any other
collateral or any amendment, waiver or other modification, whether in writing or by course of conduct or otherwise, of all or any of the Senior Obligations or Second Priority Debt Obligations or any guarantee thereof; 

  
 30 

 (d) the commencement of any Insolvency or Liquidation Proceeding in respect of the Company or any
other Grantor; or 
 (e) any other circumstances that otherwise might constitute a defense available to, or a discharge of, (i) the
Company or any other Grantor in respect of the Senior Obligations or (ii) any Second Priority Representative or Second Priority Debt Party in respect of this Agreement. 

ARTICLE VIII 

Miscellaneous 

SECTION 8.01. Conflicts. In the event of any conflict between the provisions of this Agreement and the provisions of any Senior
Debt Document or any Second Priority Debt Document, the provisions of this Agreement shall govern. 
 SECTION 8.02. Continuing
Nature of this Agreement; Severability. Subject to Section 6.04, this Agreement shall continue to be effective until the Discharge of Senior Obligations shall have occurred. This is a continuing agreement of Lien subordination, and the Senior
Secured Parties may continue, at any time and without notice to the Second Priority Representatives or any Second Priority Debt Party, to extend credit and other financial accommodations and lend monies to or for the benefit of the Company or any
Subsidiary constituting Senior Obligations in reliance hereon. The terms of this Agreement shall survive and continue in full force and effect in any Insolvency or Liquidation Proceeding. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The
parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

 SECTION 8.03. Amendments; Waivers. 

(a) No failure or delay on the part of any party hereto in exercising any right or power hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights
and remedies of the parties hereto are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any party therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any party hereto in any case
shall entitle such party to any other or further notice or demand in similar or other circumstances. 

  
 31 

 (b) This Agreement may be amended in writing signed by each Representative (in each case, acting
in accordance with the documents governing the applicable Debt Facility); provided that any such amendment, supplement or waiver which by the terms of this Agreement expressly requires the Company’s consent or which increases the obligations or
reduces the rights of the Company or any Grantor, shall require the consent of the Company. Any such amendment, supplement or waiver shall be in writing and shall be binding upon the Senior Secured Parties and the Second Priority Debt Parties and
their respective successors and assigns. 
 (c) Notwithstanding the foregoing, without the consent of any Secured Party, any Representative
may become a party hereto by execution and delivery of a Joinder Agreement in accordance with Section 8.09 of this Agreement and upon such execution and delivery, such Representative and the Secured Parties and Second Priority Debt Obligations of
the Debt Facility for which such Representative is acting shall be subject to the terms hereof. 
 SECTION 8.04. Information
Concerning Financial Condition of the Company and the Subsidiaries. The Senior Representative, the Senior Secured Parties, the Second Priority Representatives and the Second Priority Debt Parties shall each be responsible for keeping themselves
informed of (a) the financial condition of the Company and the Subsidiaries and all endorsers or guarantors of the Senior Obligations or the Second Priority Debt Obligations and (b) all other circumstances bearing upon the risk of
nonpayment of the Senior Obligations or the Second Priority Debt Obligations. The Senior Representative, the Senior Debt Parties, the Second Priority Representatives and the Second Priority Debt Parties shall have no duty to advise any other party
hereunder of information known to it or them regarding such condition or any such circumstances or otherwise. In the event that the Senior Representative, any Senior Secured Party, any Second Priority Representative or any Second Priority Debt
Party, in its sole discretion, undertakes at any time or from time to time to provide any such information to any other party, it shall be under no obligation to (i) make, and the Senior Representative, the Senior Secured Parties, the Second
Priority Representatives and the Second Priority Debt Parties shall not make or be deemed to have made, any express or implied representation or warranty, including with respect to the accuracy, completeness, truthfulness or validity of any such
information so provided, (ii) provide any additional information or to provide any such information on any subsequent occasion, (iii) undertake any investigation or (iv) disclose any information that, pursuant to accepted or
reasonable commercial finance practices, such party wishes to maintain confidential or is otherwise required to maintain confidential. 

SECTION 8.05. Subrogation. Each Second Priority Representative, on behalf of itself and each Second Priority Debt Party under its
Second Priority Debt Facility, hereby waives any rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of Senior Obligations has occurred. 

SECTION 8.06. Application of Payments. Except as otherwise provided herein, all payments received by the Senior Secured Parties
may be applied, reversed and reapplied, in whole or in part, to such part of the Senior Obligations as the Senior Secured Parties, in their sole discretion, deem appropriate, consistent with the terms of the Senior Debt Documents. Except as
otherwise provided herein, each Second Priority Representative, on 

  
 32 

 
behalf of itself and each Second Priority Debt Party under its Second Priority Debt Facility, assents to any such extension or postponement of the time of payment of the Senior Obligations or any
part thereof and to any other indulgence with respect thereto, to any substitution, exchange or release of any security that may at any time secure any part of the Senior Obligations and to the addition or release of any other Person primarily or
secondarily liable therefor. 
 SECTION 8.07. Additional Grantors. The Company agrees that, if any Subsidiary shall become a
Grantor after the date hereof, it will promptly cause such Subsidiary to become party hereto by executing and delivering an instrument in the form of Annex I (it being understood, for the avoidance of doubt, that, as of the date hereof, only
Domestic Subsidiaries are expected to become Grantors). Upon such execution and delivery, such Subsidiary will become a Grantor hereunder with the same force and effect as if originally named as a Grantor herein. The execution and delivery of such
instrument shall not require the consent of any other party hereunder, and will be acknowledged by the Designated Second Priority Representative and the Senior Representative. The rights and obligations of each Grantor hereunder shall remain in full
force and effect notwithstanding the addition of any new Grantor as a party to this Agreement. 
 SECTION 8.08. Dealings with
Grantors. Upon any application or demand by the Company or any Grantor to any Representative to take or permit any action under any of the provisions of this Agreement or under any Collateral Document (if such action is subject to the provisions
hereof), the Company or such Grantor, as appropriate, shall furnish to such Representative (i) a certificate of a Responsible Officer (an “Officer’s Certificate”) and (ii) upon the Second Lien Agent’s reasonable
request (which request is made at the direction of the Designated Second Priority Representative), an opinion of counsel, in each case stating that all conditions precedent, if any, provided for in this Agreement or such Collateral Document, as the
case may be, relating to the proposed action have been complied with, except that in the case of any such application or demand as to which the furnishing of such documents is specifically required by any provision of this Agreement or any
Collateral Document relating to such particular application or demand, no additional certificate or opinion need be furnished. 

  
 33 

 SECTION 8.09. Additional Debt Facilities. To the extent, but only to the extent,
permitted by the provisions of the Senior Debt Documents and the Second Priority Debt Documents, the Company may incur or issue and sell one or more series or classes of Second Priority Debt. Any such additional class or series of Second Priority
Debt (the “Second Priority Class Debt”) may be secured by a second priority, subordinated Lien on Shared Collateral, in each case under and pursuant to the relevant Second Priority Collateral Documents for such Second Priority Class
Debt, if and subject to the condition that the Representative of any such Second Priority Class Debt (each, a “Second Priority Class Debt Representative”), acting on behalf of the holders of such Second Priority Class Debt (such
Representative and holders in respect of any Second Priority Class Debt being referred to as the “Second Priority Class Debt Parties”), becomes a party to this Agreement by satisfying conditions (i) through (iii), as applicable, of
the immediately succeeding paragraph. In order for a Second Priority Class Debt Representative to become a party to this Agreement: 

(i) such Second Priority Class Debt Representative shall have executed and delivered a Joinder Agreement substantially in the
form of Annex II (with such changes as may be reasonably approved by the Senior Representative and such Second Priority Class Debt Representative) pursuant to which it becomes a Representative hereunder, and the Second Priority Class Debt in respect
of which such Second Priority Class Debt Representative is the Representative and the related Second Priority Class Debt Parties become subject hereto and bound hereby; 

(ii) the Company shall have delivered to each Representative an Officer’s Certificate stating that the conditions set
forth in this Section 8.09 are satisfied with respect to such Second Priority Class Debt and, if requested, true and complete copies of each of the Second Priority Debt Documents relating to such Second Priority Class Debt, certified as being true
and correct by a Responsible Officer of the Company; and 
 (iii) the Second Priority Debt Documents relating to such Second
Priority Class Debt shall provide that each Second Priority Class Debt Party with respect to such Second Priority Class Debt will be subject to and bound by the provisions of this Agreement in its capacity as a holder of such Second Priority Class
Debt. 
 SECTION 8.10. Consent to Jurisdiction; Waivers. Each Representative, on behalf of itself and the Secured Parties of the
Debt Facility for which it is acting, irrevocably and unconditionally: 
 (a) submits for itself and its property in any
legal action or proceeding relating to this Agreement and the Collateral Documents, or for recognition and enforcement of any judgment in respect thereof, to the exclusive jurisdiction of the courts of the State of New York located in the Borough of
Manhattan, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof; 

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or
hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same; 

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or
certified mail (or any substantially similar form of mail), postage prepaid, to such Person (or its Representative) at the address referred to in Section 8.11 or by a procedure permitted under the relevant Senior Debt Document or Second Priority
Debt Documents, as the case may be; 
 (d) agrees that nothing herein shall affect the right of any other party hereto (or
any Secured Party) to effect service of process in any other manner permitted by law; and 
 (e) waives, to the maximum
extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 8.10 any special, exemplary, punitive or consequential damages.
