 Section 2.2 Other Revenues. Notwithstanding that the Security Interests granted to the Collateral Agent cover all of the Accounts, in the event that Other Revenues are included in the
Accounts, then the Collateral Agent agrees that the Collateral Agent shall retain from such Accounts an amount equal to the difference between the resale price of the natural gas less the actual price paid or owed by the Grantor for the natural gas

funds are Other Revenues (i.e., are not the Grantor’s funds) before such funds are collected and applied by the Collateral Agent to the Secured Obligations. The Collateral Agent shall not be liable, however, for any actions by the Collateral
Agent which are taken in compliance with the terms of this Agreement and the Indenture with respect to funds that are Other Revenues and which are taken before the Collateral Agent receives such evidence that such funds are Other Revenues.

upon the Secured Obligations or otherwise) to the Grantor for payments actually received. The Grantor agrees to indemnify and hold harmless the Collateral Agent and the Trustee against any and all liabilities, actions, claims, judgments, costs,
charges and attorneys’ fees by reason of any third party claim to the Collateral, and the Collateral Agent shall have the right to defend against any such third party claims or actions, employing attorneys of the Collateral Agent’s own
selection and if not furnished with indemnity satisfactory to them, the Collateral Agent shall have the right to compromise and adjust any such claims, actions and judgments, and in addition to the rights to be indemnified as herein provided, all
amounts paid by the Collateral Agent in compromise, satisfaction or discharge of any such claims, actions or judgments, and all court costs, attorneys’ fees and other expenses of every character expended by the Collateral Agent pursuant to the
provisions of this Section 2.3 shall be a demand obligation (which obligation the Grantor hereby expressly promises to pay) owing by the Grantor and shall be a part of the Secured Obligations. The Grantor agrees to pay, indemnify, and
hold the Collateral Agent and the Trustee harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to
the execution, delivery, enforcement, performance and administration of this Agreement and the other Note Documents. WITHOUT LIMITATION, IT IS THE INTENTION OF GRANTOR AND GRANTOR AGREES THAT THE FOREGOING RELEASES AND INDEMNITIES SHALL APPLY TO
EACH INDEMNIFIED PARTY WITH RESPECT TO ALL CLAIMS, DEMANDS, LIABILITIES, LOSSES, DAMAGES (INCLUDING WITHOUT LIMITATION 

 
CONSEQUENTIAL DAMAGES, CAUSES OF ACTION, JUDGMENTS, PENALTIES, COSTS AND EXPENSES AND FURTHER INCLUDING WITHOUT LIMITATION REASONABLE ATTORNEYS’ FEES AND EXPENSES, WHICH IN WHOLE OR IN PART

Section 4.3 Filing. The Grantor authorizes the Collateral Agent to file or record financing statements, any amendments
thereto and other filing or recording documents or instruments with respect to the Collateral without the signature of the Grantor in such form and in such offices as the Collateral Agent reasonably determines appropriate to perfect the security

reproduction of this Agreement shall be sufficient as a financing statement or other filing or recording document or instrument for filing or recording in any jurisdiction. The Grantor shall pay all costs of or incidental to the recording or filing

Collateral that may violate the terms of any insurance covering the Collateral or any part thereof. 
 Section 4.5
Insurance and Notice. (a) The Grantor shall provide or cause to be provided, insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of the Grantor, are adequate and
appropriate for the conduct of the business of the Grantor in a prudent manner, with reputable insurers or with the government of the United States of America, Canada 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 the Grantor, for companies similarly situated in the industry. Within 30 days after the date hereof, the Grantor shall furnish to the Collateral Agent policies or certificates
of insurance covering the property and assets of the Grantor. Each policy shall: (x) reflect the 

 
Collateral Agent, for its benefit and the benefit of the other Secured Parties, as additional insured and loss payee and mortgagee and shall otherwise bear endorsements of the character
reasonably acceptable to the Collateral Agent; (y) contain an agreement by the insurer, if available at reasonable cost, not to cancel, amend, materially reduce the amount or materially change the coverage under the policy without giving the
Collateral Agent at least thirty (30) days prior written notice of its intention to do so and (z) if reasonably requested by the Collateral Agent, include a breach of warranty clause. The Grantor shall furnish or cause to be furnished to
the Collateral Agent from time to time, and in no event less than once per calendar year, a compliance certificate from an independent third-party insurance consultant with experience in the Oil and Gas Business certifying that the insurance with
respect to the Collateral is in full force and effect and that it fully complies with requirements that are customary in the Oil and Gas Business. In the event the Grantor should, for any reason whatsoever, fail to keep the Collateral or any part
thereof so insured, then the Collateral Agent, if it so elects, may itself have such insurance effected in such amounts and with such companies as it may deem proper and may pay the premiums therefor and the Grantor shall reimburse the Collateral
Agent upon demand for the amount of the premiums paid, together with interest thereon until paid at the rate equal to the rate of interest charged on the principal of any of the Notes plus one (1%) percent. The Collateral Agent shall not be
responsible for the solvency of any company issuing any insurance policy, whether or not selected or approved by it, or for the collection of any amounts due under any such policy, and shall be responsible and accountable only for such money as may
be actually received by the Collateral Agent. The Grantor shall promptly notify the Collateral Agent if any portion of the “Collateral” (as such term is defined in the Indenture) in excess of $1,500,000 is physically damaged, destroyed or
condemned; provided that the foregoing shall not include damages to wells or well bores or oil and gas properties incurred in the ordinary course of business of drilling or producing such properties in an aggregate amount of less than $5,000,000. In
the event of any loss under any of such policies, the Collateral Agent shall pay the net proceeds thereof to the Grantor, either wholly or in part, unless an Event of Default has occurred and is continuing, in which event the Collateral Agent may
hold the net proceeds as additional Collateral or pay the net proceeds to the Grantor under such conditions as the Collateral Agent may determine to enable the Grantor to repair or restore the Collateral. In the event of foreclosure of this Mortgage
or other transfer of title to the Mortgaged Property following an Event of Default, all right and interest of the Grantor in and to any property insurance policies then in force shall pass to the Collateral Agent. 

(b) Within 30 days after the date hereof, the Collateral Agent shall have received, with respect to this Agreement, policies or
certificates of insurance covering the property and assets of the Grantor for the benefit of the Collateral Agent and the other Secured Parties (as defined in the Security Documents), as additional insured and loss payee. 

Section 4.6 Equipment Not Fixtures. If, in the opinion of the Collateral Agent any of the Equipment is or may become part of
any real property, the Grantor shall furnish to the Collateral Agent a written waiver by the record owner of such realty (immovable) of all interest in such Collateral and a written subordination to the Collateral Agent’s Security Interest by
any Person who has a Lien on such realty (immovable) which is or may be superior to the Collateral Agent’s Security Interest hereunder. 

 Section 4.7 Accounts Collection. The Grantor shall cause to be collected from
its account debtors, as and when due in the ordinary course of business consistent with prudent business practice (including, without limitation, Accounts which are delinquent, such Accounts to be collected in accordance with lawful collection
procedures and generally accepted commercial collection procedures) and shall apply forthwith upon receipt thereof all such amounts as are so collected to the outstanding balance of such Account, except that the Grantor may, with respect to an
Account, allow in the ordinary course of business (i) a refund or credit due as a result of returned or damaged or defective goods and (ii) such extensions of time to pay amounts due in respect of Accounts and such other modifications of
payment terms or settlements in respect of Accounts as shall be commercially reasonable in the circumstances, all in accordance with the Grantor’s ordinary course of business consistent with its collection practices as in effect from time to
time. The costs and expenses (including, without limitation, attorneys’ fees) of collection, whether incurred by the Grantor or the Collateral Agent, shall be borne by the Grantor. 

Section 4.8 [Reserved]  
 Section 4.9 Control Agreements. (a) If the Grantor shall now or hereafter have rights in any Securities Accounts with any securities intermediary, the Grantor shall immediately notify the
Collateral Agent and, if such Securities Accounts have an aggregate value in excess of $500,000, at the Collateral Agent’s request and option, cause the securities intermediaries maintaining such accounts to enter into one or more control
agreements in form and substance reasonably satisfactory to the Collateral Agent under which they agree to comply with entitlement orders or other instructions originated by the Collateral Agent to such securities intermediary as to the securities
or other financial assets contained therein without consent from the Grantor, but only to the extent required so that no more than $500,000 of assets maintained in such accounts are not subject to such control agreements. 

(b) If the Grantor shall now or hereafter have rights in any Deposit Accounts maintained with any bank, the Grantor shall immediately

substance reasonably satisfactory to the Collateral Agent under which they agree to comply with instructions to such bank originated by the Collateral Agent directing the disposition of funds in such Deposit Accounts without consent from the
Grantor, but only to the extent required so that no more than $500,000 of deposits in such accounts are not subject to such control agreements.

ordinary course of business. 
 Section 4.11 Governmental Accounts. If more than 5% of the Accounts included in the

Collateral; and (iii) execute, acknowledge, deliver and record any document or instrument (including specifically any financing statement) necessary, desirable or proper in any jurisdictions to protect the Lien and Security Interest hereunder

 (c) The Grantor shall furnish to the Collateral Agent from time to time statements and
schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Collateral Agent may reasonably request, all in reasonable detail. 

Section 4.15 Collateral Indemnity. If the validity or priority of this Agreement or any rights, Security Interests or other
interests created or evidenced hereby shall be attacked, endangered or questioned or if any legal proceedings are instituted with respect thereto, the Grantor shall give prompt written notice thereof to the Collateral Agent and at the Grantor’s
own cost and expense shall diligently endeavor to cure any defect that may be developed or claimed, and shall take all necessary and proper steps for the defense of such legal proceedings, and the Collateral Agent (whether or not named as a party to
legal proceedings with respect thereto) is hereby authorized and empowered to take such additional steps as in its judgment and discretion may be necessary or proper for the defense of any such legal proceedings or the protection of the validity or
priority of this Agreement and the rights, Security Interests and other interests created or evidenced hereby, and all expenses so incurred of every kind and character shall be a demand obligation owing by the Grantor to the Collateral Agent and
shall be a part of the Secured Obligations. 
 Section 4.16 Receivables. Other than in the ordinary course of
business consistent with its past practice, Grantor will not (i) grant any extension of the time of payment of any Receivable, (ii) compromise or settle any Receivable for less than the full amount thereof, (iii) release, wholly or

outstanding Receivables. 
 Section 4.17 Delivery of Instruments and Chattel Paper. All (i) Promissory Notes
issued by a subsidiary of the Grantor and held by the Grantor and (ii) if any amount payable under or in connection with any of the other Collateral shall be or become evidenced by any Instrument (other than checks received in the ordinary
course of business) or Chattel Paper, such Instrument or Chattel Paper shall be immediately delivered to the Collateral Agent, duly indorsed in a manner satisfactory to the Collateral Agent, to be held as Collateral pursuant to this Agreement,

Section 4.20 Letter-of-Credit Rights. If the Grantor is at any time a beneficiary under any letters of credit now or
hereafter issued in favor of the Grantor in amounts in the aggregate in excess of $500,000, the Grantor shall promptly notify the Collateral Agent thereof and the Grantor shall, at the request of the Collateral Agent, pursuant to an agreement in
form and substance reasonably satisfactory to the Collateral Agent, use commercially reasonable efforts to either (i) arrange for the issuer and any confirmer of letters of credit to consent to an assignment to the Collateral Agent of the
proceeds of any drawing under such letters of credit or (ii) arrange for the Collateral Agent to become the transferee beneficiary of such letters of credit, with the Collateral Agent agreeing, in each case, that the proceeds of any drawing

signed by the Grantor of the brief details thereof and grant to the Collateral Agent in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance

 ARTICLE 5 
 DEFAULT 
 Section 5.1 Use of Collateral. Unless an Event of Default
shall have occurred and be continuing and subject to the terms of the Intercreditor Agreements, the Grantor shall have the right (a) to remain in possession and retain exclusive control of the Collateral (other than anything constituting part
of the Collateral and required to be deposited in an account subject to the control of the Collateral Agent pursuant to Section 4.10 of this Agreement), (b) to retain exclusive control over the Collateral (except as otherwise
provided in this Agreement and the other Security Documents), (c) to freely operate the Collateral, (d) to alter or repair the Collateral, and (e) to collect, invest and dispose of any income from the Collateral. Upon an Event of
Default that has occurred and is continuing, to the extent permitted by law and after notice by the Collateral Agent to the Grantor, these rights shall cease, and the Collateral Agent shall be entitled to exercise remedies in accordance with this
Article 5. 
 Section 5.2 Remedies. (a) Subject to the terms of the Intercreditor Agreements, upon the
occurrence of any Event of Default, the Collateral Agent may take such action, without notice or demand, as it deems advisable to protect and enforce its rights against the Grantor and in and to the Collateral, including, but not limited to, the
following actions, each of which may be pursued concurrently or otherwise, at such time and in such order as the Collateral Agent may determine, in its sole discretion, without impairing or otherwise affecting the other rights and remedies of the
Collateral Agent: (i) institute proceedings for the complete foreclosure of this Agreement in which case the Collateral or any part thereof may be sold for cash or upon credit in one or more portions; (ii) to the extent permitted and
pursuant to the procedures provided by applicable law, institute proceedings for the partial foreclosure of this Agreement for the portion of the Secured Obligations then due and payable, subject to the continuing Security Interests of this
Agreement for the balance of the Secured Obligations not then due; (iii) institute an action, suit or proceeding in equity for the specific performance of any covenant, condition or agreement contained in this Agreement, the Indenture, or any
Secured Hedge/LC Agreement; (iv) recover judgment on the Notes or any other Secured Obligation either before, during or after any proceedings for the enforcement of this Agreement; (v) apply for the appointment of a trustee, receiver,
liquidator or conservator of the Collateral, without regard for the adequacy of the security for the Secured Obligations and without regard for the solvency of the Grantor or of any person, firm or other entity liable for the payment of the Secured
Obligations; or (vi) pursue such other remedies as the Collateral Agent may have under applicable law. 
 (b) The proceeds
or avails of any sale made under or by virtue of this Article 5, together with any other sums which may be held by the Collateral Agent under this Agreement, whether under the provisions of this Article 5 or otherwise, shall be applied to the
Secured Obligations in such manner as the Collateral Agent, in its sole discretion, shall determine. 
 (c) Upon any sale made
under or by virtue of this Article 5, the Collateral Agent may bid for and acquire the Collateral or any part thereof and in lieu of paying cash therefor may make settlement for the purchase price by crediting upon the Secured Obligations the net
sales price after deducting therefrom the expenses of the sale and the costs of the action and any other sums which the Collateral Agent is authorized to deduct under this Agreement. 

Section 5.3 Proceeds; Receivables. (a) Subject to the terms of the Intercreditor Agreements, if an Event of Default
shall have occurred and be continuing, (i) all payments (in the form of checks, drafts, cash or otherwise) received by the Grantor in satisfaction, in whole or in part, of any Accounts, Receivables or General Intangibles (or Proceeds
therefrom), when collected by the Grantor, shall be immediately (and, in any event, within one Business Day) 

 
deposited by the Grantor in the exact form received, duly indorsed by the Grantor to the Collateral Agent if required, in an account subject to the control of the Collateral Agent pursuant to a
control agreement; and (ii) until so deposited, shall be held by the Grantor in trust for the Collateral Agent, segregated from other funds of the Grantor. All Proceeds and payments of Receivables while so controlled by the Collateral Agent (or
by the Grantor in trust for the Collateral Agent) shall continue to be held as a security interest in favor of the Collateral Agent and the Secured Parties to secure the Secured Obligations and shall not constitute payment thereof until applied as
provided in clause (b) below. 
 (b) Subject to the terms of the Intercreditor Agreements, if an Event of Default shall
have occurred and be continuing, at any time at the Collateral Agent’s election, the Collateral Agent may apply all or any part of the Proceeds constituting Collateral, whether or not held in a Deposit Account subject to the control of the
Collateral Agent, in payment of the Secured Obligations in such order as the Collateral Agent may elect, and any part of such funds which the Collateral Agent elects not so to apply shall continue to be held as Collateral for the Secured
Obligations. Any balance of such Proceeds remaining after all Events of Default have been cured or waived shall be paid over to the Grantor or to whomsoever may be lawfully entitled to receive the same. 

Section 5.4 [Reserved]. 
 Section 5.5 Remedies Under the UCC; Sale of Non-Equity Collateral. (a) Upon the occurrence of an Event of Default, the Collateral Agent may exercise its rights of enforcement with respect
to the Collateral under the UCC or under any other law, statute, order, rule or regulation, in force in any state, to the extent the same is applicable. Without limiting the generality of the foregoing, the Collateral Agent, without demand of
performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Grantor or any other Person (all and each of which demands, defenses, advertisements and
notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of
and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Collateral Agent or elsewhere upon such terms
and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. 
 (b) The Secured Parties shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right or equity or redemption in the Grantor, which right or equity is hereby waived and released. The Grantor shall execute and deliver such documents and take such other action as the Collateral Agent deems
necessary or advisable in order that any such sale may be made in compliance with law. Upon any such sale the Collateral Agent shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral so sold. Each purchaser at
any such sale shall hold the Collateral so sold to it absolutely and free from any claim or right of whatsoever kind, including any equity or right of redemption of the Grantor which may be waived, and the Grantor, to the extent permitted by law,
hereby 

 
specifically waives all rights of redemption, stay or appraisal which it has or may have under any law now existing or hereafter adopted. The Collateral Agent shall apply the net proceeds of any
action taken by it pursuant to this Section 5.5(b), after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating
to the Collateral or the rights of the Secured Parties, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Secured Obligations, in such order as the Collateral Agent may elect
and only after such application and after the payment by the Secured Parties of any other amount required by any provision of law, including, without limitation, Section 9-615(a)(3) and (4) of the UCC, need the Secured Parties account for
the surplus, if any, to the Grantor. Should the Collateral be disposed of other than by sale, any proceeds of such disposition shall be treated as if the same were sales proceeds. To the extent permitted by applicable law, the Grantor waives all
claims, damages and demands it may acquire against the Secured Parties arising out of the exercise by them of any rights hereunder. 
 (c) If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days prior to such sale or other
disposition. Shorter or no notice shall be reasonable as to any Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market. The notice (if any) of such sale shall (l) in case
of a public sale, state the time and place fixed for such sale, and (2) in the case of a private sale, state the day after which such sale may be consummated. The Collateral Agent shall not be obligated to make any such sale pursuant to any
such notice. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any
time or place to which the same may be so adjourned. 
 (d) In case of any sale of all or any part of the Collateral on credit
or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the selling price is paid by the purchaser thereof, but the Collateral Agent shall not incur any liability in case of the failure of such purchaser to take
up and pay for the Collateral so sold and, in case of any such failure, such Collateral may again be sold upon like notice. The Collateral Agent shall not be liable for any depreciation in the value of the Collateral. All rights to marshaling of
assets of the Grantor, including any such right with respect to the Collateral, are hereby waived. 
 (e) The Grantor recognizes
that the Collateral Agent may be unable to effect a public sale of any or all of the Collateral. The Collateral Agent shall incur no liability as a result of a private sale of the Collateral or any part thereof. The Grantor hereby waives, to the
extent permitted by applicable law, any claims against the Collateral Agent arising by reason of the fact that the price at which the Collateral may have been sold at such private sale was less than the price which might have been obtained at a
public sale or was less than the aggregate amount of the outstanding Secured Obligations, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree. 

Section 5.6 [Reserved]. 

 Section 5.7 Foreclosure; Receiver. The Collateral Agent, instead of exercising
the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to foreclose the Security Interests and sell the Collateral, or any portion thereof, under a judgment or decree of a court or courts of competent
jurisdiction. Moreover, the Collateral Agent may apply for and obtain, without notice and upon ex parte application, the appointment of a receiver for the Collateral without regard to the Grantor’s financial condition or solvency, the adequacy
of the Collateral to secure the payment or performance of the Secured Obligations, or the existence of any waste to the Collateral. In the event that the Collateral Agent institutes an action to recover any Collateral or appoint a receiver or seeks
the recovery of any Collateral or the appointment of a receiver by way of a pre-judgment remedy in an action against the Grantor, the Grantor waives the posting of any bond which might otherwise be required. 

Section 5.8 Accounts. While an Event of Default has occurred and is continuing, the Grantor shall make no material change to
the terms of any Account without the prior written permission of the Collateral Agent. Upon the occurrence and during the continuance of an Event of Default, the Grantor upon request of the Collateral Agent shall promptly notify (and the Grantor
hereby authorizes the Collateral Agent so to notify) each account debtor in respect of any Account or General Intangible that such Collateral has been assigned to the Collateral Agent hereunder, and that any payments due or to become due in respect
of such Collateral are to be made directly to the Collateral Agent or its designee, and the Collateral Agent may demand, sue for, collect and receive all such Accounts or General Intangibles. 

Section 5.9 General Authority. The Grantor hereby irrevocably appoints the Collateral Agent its agent and attorney in fact,
with full power of substitution, in the name of the Grantor or the Collateral Agent, for the sole use and benefit of the Collateral Agent, but at the Grantor’s expense, to exercise, at any time and from time to time while an Event of Default
has occurred and is continuing, all or any of the following powers with respect to all or any of the Collateral: 
 (i) to
indorse the name of the Grantor upon any check, draft, note or other instrument payable to the Grantor evidencing payment upon any Account or General Intangible, 
 (ii) to notify postal service authorities to change the address for delivery of the Grantor’s mail to a “lockbox” address designated and controlled by the Collateral Agent, and to receive,
open and dispose of all mail addressed to the Grantor, 
 (iii) to pay or discharge taxes and Liens levied or placed on or
threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement or any other Security Document and pay all or any part of the premiums therefor and the costs thereof, 

(iv) to execute, in connection with any sale provided for in this Agreement, any indorsements, assignments or other instruments of
conveyance or transfer with respect to the Collateral, 

 (v) to direct any party liable for any payment under any of the Collateral to make payment
of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct, 

(vi) to demand, sue for, collect, receive and give acquittance for any and all Accounts and other moneys due or to become due for or as
Collateral or by virtue thereof, 
 (vii) to defend any suit, action or proceeding brought against the Grantor with respect to
any Collateral, 
 (viii) to settle, compromise, compound, prosecute or defend any action or proceeding with respect to any of
the Collateral, 
 (ix) to extend the time of payment of any or all of the Collateral and to make any allowance and other
adjustments with reference thereto, and 
 (x) generally, to sell, transfer, pledge and make any agreement with respect to or
otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent’s option and the Grantor’s expense (including reasonable
attorneys’ fees), at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Security Interests therein and to effect the intent of this
Agreement, all as fully and effectively as the Grantor might do. 
 The aforesaid mandate and power of attorney, being coupled with an interest,
is irrevocable so long as any of the Secured Obligations remains outstanding. Notwithstanding the foregoing, the Collateral Agent shall not exercise the foregoing power of attorney except following the occurrence and during the continuance of an
Event of Default. 
 Section 5.10 Assemble Collateral. For the purpose of enforcing any and all rights and remedies
under this Agreement the Collateral Agent may (i) require the Grantor to, and the Grantor agrees that it shall, at its expense and upon the request of the Collateral Agent, forthwith assemble all or any part of the Collateral as directed by the
Collateral Agent and make it available at a place designated by the Collateral Agent which is, in its opinion, reasonably convenient to the Collateral Agent and the Grantor, whether at the premises of the Grantor or otherwise, and the Collateral
Agent shall be entitled to specific performance of this obligation, (ii) to the extent permitted by applicable law of any applicable state, enter, with or without process of law and without breach of the peace, any premise where any of the
Collateral is or may be located, and without charge or liability to it seize and remove such Collateral from such premises, (iii) have access to and use the Grantor’s books and records relating to the Collateral and (iv) prior to the
disposition of the Collateral, store or transfer it without charge in or by means of any storage or transportation facility owned or leased by the Grantor, process, repair or recondition it or otherwise prepare it for disposition in any manner and
to the extent the Collateral Agent deems appropriate and, in connection with such preparation and disposition, use without charge any trademark, trade name, copyright, patent or technical process used by the Grantor. 

 Section 5.11 Limitation on Duty of the Collateral Agent. Beyond the exercise of
reasonable care in the custody thereof, the Collateral Agent shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon. The Collateral Agent shall be deemed to
have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and shall not be liable or responsible for any loss or damage to
any of the Collateral, or for any diminution in the value thereof, by reason of the act or omission of any warehouseman, carrier, forwarding agency, consignee or other agent or bailee selected by the Collateral Agent in good faith. The Grantor
agrees that the Collateral Agent shall not be obligated to preserve rights against prior parties obligated on any instruments. The obligation of the Collateral Agent to act under this Security Agreement is subject to the provisions of
Section 7.2(b), Section 11.2(a), Section 12.4 and Section 12.5 of the Indenture. This Section 5.11 is subject to and shall not diminish the Collateral Agent’s right to indemnification pursuant to
Section 2.3. 
 Section 5.12 Appointment by the Collateral Agent. At any time or times, in order to
comply with any legal requirement in any jurisdiction, the Collateral Agent may appoint a bank or trust company or one or more other Persons with such power and authority as may be necessary for the effectual operation of the provisions hereof and
may be specified in the instrument of appointment. 
 Section 5.13 Expenses. In the event that the Grantor fails to
comply with any provisions of this Agreement or the Security Documents, such that the value of any Collateral or the validity, perfection, rank or value of any Security Interest hereunder is thereby diminished or potentially diminished or put at
risk, the Collateral Agent may, but shall not be required to, effect such compliance on behalf of the Grantor, and the Grantor shall reimburse the Collateral Agent for the costs thereof on demand. All insurance expenses and all expenses of
protecting, storing, warehousing, appraising, preparing for sale, handling, maintaining and shipping the Collateral, any and all excise, property, sales, and use taxes imposed by any federal, state or local authority on any of the Collateral, all
expenses in respect of periodic appraisals and inspections of the Collateral to the extent the same may be requested from time to time, and all expenses in respect of the sale or other disposition thereof shall be borne and paid by the Grantor; and
if the Grantor fails to promptly pay any portion thereof when due, the Collateral Agent may, at its option, but shall not be required to, pay the same and charge the Grantor’s account therefor, and the Grantor agrees to reimburse the Collateral
Agent therefor on demand. All sums so paid or incurred by the Collateral Agent for any of the foregoing and any and all other sums for which the Grantor may become liable hereunder and all costs and expenses (including reasonable attorneys’
fees, legal expenses and court costs) incurred by the Collateral Agent in enforcing or protecting the Security Interests or any of its rights or remedies under this Agreement or the other Security Documents, shall, together with interest thereon
until paid at the rate equal then highest rate of interest charged on the principal of any of the Notes plus one (1%) percent, be additional Secured Obligations hereunder and Grantor agrees to pay all of the foregoing sums promptly on demand.

 Section 5.14 Deficiency. The Grantor shall remain liable for any deficiency if the proceeds of any sale or other
disposition of the Collateral are insufficient to satisfy its Secured Obligations and the fees and disbursements of any attorneys employed by the Secured Parties or the Collateral Agent to collect such deficiency.

Security Interests granted hereunder in the Collateral shall be released only in accordance with the provisions of Section 11.5 of the Indenture.

 Section 2. Securities Subject to
this Agreement. 
 (a) Transfer Restricted Securities. The securities entitled to the benefits of this Agreement are
the Transfer Restricted Securities. 
 (b) Holders of Transfer Restricted Securities. A Person is deemed to be a holder of
Transfer Restricted Securities (each, a “Holder”) whenever such Person owns Transfer Restricted Securities. 

Section 3. Registered Exchange Offer. 
 (a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy (after the procedures set forth in Section 6(a)(i) hereof have been complied with), or there are
no Transfer Restricted Securities outstanding, the Company and the Guarantors shall (i) cause the Exchange Offer Registration Statement to be filed with the Commission, (ii) use their reasonable best efforts to cause such Exchange Offer
Registration Statement to become effective, (iii) in connection with the foregoing, use reasonable best efforts to (A) file all pre-effective amendments to such Exchange Offer Registration Statement as may be necessary in order to cause it
to become effective, (B) file, if applicable, a post-effective amendment to such Exchange Offer Registration Statement pursuant to Rule 430A under the Securities Act and (C) cause all necessary filings, if any, in connection with the
registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, provided, however, that neither the Company
nor any Guarantor shall be required to take any action that would subject them to general service of process or taxation in any jurisdiction where they are not already subject, and (iv) upon the effectiveness of such Exchange Offer Registration
Statement, commence the Exchange Offer. Each of the Company and the Guarantors shall file the Exchange Offer Registration Statement with the Commission as soon as practicable after the Closing Date and use reasonable best efforts to have the
Exchange Offer Registration Statement declared effective as soon as practicable thereafter and in no event Consummate the Exchange Offer later than the 180th day after the Closing Date (such 180th day being the “Exchange Date”). The
Exchange Offer, if required pursuant to this Section 3(a), shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Transfer Restricted Securities and to permit resales of Initial
Securities held by Broker-Dealers as contemplated by Section 3(c) hereof. 
 (b) If an Exchange Offer Registration Statement
is required to be filed and declared effective pursuant to Section 3(a) above, the Company and the Guarantors shall use reasonable best efforts to cause the Exchange Offer Registration Statement to be effective continuously, and shall keep the
Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 20 Business
Days after the date notice of the Exchange Offer is mailed to the Holders. The Company shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the Exchange Securities shall be included
in the Exchange Offer Registration Statement. 

  
 4 

 (c) The Company shall indicate in a “Plan of Distribution” section contained in
the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds Transfer Restricted Securities that were acquired for its own account as a result of market-making activities or other trading activities
(other than Initial Securities acquired directly from the Company), may exchange such Transfer Restricted Securities pursuant to the Exchange Offer. Such “Plan of Distribution” section shall also contain all other information with respect
to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer except to the extent required by the Commission. 
 Because such Broker-Dealer may be
deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with resales of any Exchange Securities received by such
Broker-Dealer in the Exchange Offer, the Company and the Guarantors shall permit the use of the Prospectus contained in the Exchange Offer Registration Statement by such Broker-Dealer to satisfy such prospectus delivery requirement. The Company and
the Guarantors shall use their reasonable best efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure
that it is available for resales of Transfer Restricted Securities acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading activities, and to ensure that it conforms with the requirements of this
Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the date on which the Exchange Offer Registration Statement is
declared effective and (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities. 
 Upon request, the Company shall provide sufficient copies of the latest version of such Prospectus to such Broker-Dealers within five Business Days after such request at any time during such 180-day (or
shorter, as provided in the foregoing sentence) period in order to facilitate such resales. 
 Section 4. Shelf
Registration. 
 (a) Shelf Registration. If (i) the Company and the Guarantors are not required to file an
Exchange Offer Registration Statement or to Consummate the Exchange Offer solely because the Exchange Offer is not permitted by applicable law or Commission policy (after the procedures set forth in Section 6(a)(i) hereof have been
complied with), (ii) for any reason the Exchange Offer is not Consummated by the Exchange Date, or (iii) prior to the Exchange Date, any Holder of Transfer Restricted Securities notifies the Company that (1) such Holder is prohibited
by applicable law or Commission policy from participating in the Exchange Offer, (2) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus
contained in the 

  
 5 

 
Exchange Offer Registration Statement is not available for such resales by such Holder, or (3) such Holder is a Broker-Dealer and holds Transfer Restricted Securities acquired directly from
the Company or one of its Affiliates, then the Company and the Guarantors shall use their reasonable best efforts to file and cause to be declared effective a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be
an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”) on or prior to the later of (x) the 90th day after the date such obligation arises pursuant to this clause and (y) the 90th day after the Closing date (such date being the “Shelf
Effectiveness Deadline”), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof. 

Each of the Company and the Guarantors shall use their reasonable best efforts to keep such Shelf Registration Statement continuously
effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Transfer Restricted Securities by the Holders of such Securities
entitled to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement in all material respects, the Securities Act and the policies, rules and regulations of the Commission as announced from time
to time, from the date on which the Shelf Registration Statement is declared effective by the Commission until the expiration of the one-year period referred to in Rule 144 applicable to securities held by non-affiliates under the Securities Act (or
shorter period that will terminate when all the Transfer Restricted Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement). 

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer
Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 10 days after receipt of a request
therefor, such information as required by Regulation S-K of the Securities Act or, reasonably requested by the Company for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. No Holder
shall be entitled to Additional Interest pursuant to Section 5 hereof unless and until (and from and after such time) such Holder shall have provided all such information. Each Holder as to which any Shelf Registration Statement is being
effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading and shall promptly supply such other
information as the Company may from time to time reasonably request. 
 Section 5. Additional Interest. If
(i) the Exchange Offer has not been Consummated by the Exchange Date, (ii) any Shelf Registration Statement, if required hereby, has not been declared effective by the Commission by the Shelf Effectiveness Deadline or (iii) any
Registration Statement required by this Agreement has been declared effective but ceases to be effective or otherwise available in a period during which it is required to be effective under this Agreement (each such event referred to in clauses
(i) through (iii), a “Registration Default”), the Company hereby agrees that the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum during the 90-day period immediately
following the occurrence of any Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period (such increase, “Additional Interest”), but in no event

  
 6 

 
shall such increase exceed 1.00% per annum on the principal amount of such Transfer Restricted Securities; provided that the Company and the Guarantors shall in no event be required
to pay Additional Interest for more than one Registration Default at any given time. At the cure of all Registration Defaults relating to the particular Transfer Restricted Securities, the interest rate borne by the relevant Transfer Restricted
Securities will be reduced to the original interest rate borne by such Transfer Restricted Securities. 
 All accrued Additional
Interest shall be paid by the Company and the Guarantors (or the Company and the Guarantors will cause the Paying Agent to make such payment on their behalf) to the Holders entitled thereto, in the manner provided for the payment of interest in the
Indenture, on each Interest Payment Date, as more fully set forth in the Indenture, the Initial Notes and the Exchange Notes. All obligations of the Company and the Guarantors set forth in the preceding paragraph that are outstanding with respect to
any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such security shall have been satisfied in full. 

Section 6. Registration Procedures. 
 (a) Exchange Offer Registration Statement. In connection with the Exchange Offer, if required pursuant to Section 3(a) hereof, the Company and the Guarantors shall comply with all of the
provisions of Section 6(c) hereof, shall use their reasonable best efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and
shall comply with all of the following provisions: 
 (i) [reserved] 

(ii) As a condition to its participation in the Exchange Offer pursuant to the terms of this Agreement, each Holder of Transfer
Restricted Securities (including, without limitation, any Holder who is a Broker-Dealer) shall furnish, upon the request of the Company, prior to the Consummation of the Exchange Offer, a written representation to the Company and the Guarantors
(which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an Affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and
has no arrangement or understanding with any Person to participate in, a distribution of the Exchange Securities to be issued in the Exchange Offer, (C) it is acquiring the Exchange Securities in its ordinary course of business, and
(D) only if such Holder is a Broker-Dealer that will receive Exchange Securities in exchange for Initial Securities that such Broker-Dealer acquired for its own private account as a result of market making or other trading activities, it will
deliver a Prospectus, as required by law, in connection with any sale of such Exchange Securities. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer.
As a condition to its participation in the Exchange Offer, each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the
Exchange Offer (1) could not, under Commission policy as in effect on the date of this Agreement, rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital
Holdings Corporation  

  
 7 

 
(available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters, and
(2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration
statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities obtained by such Holder in exchange for Transfer Restricted Securities acquired
by such Holder directly from the Company. 
 (b) Shelf Registration Statement. If required pursuant to Section 4, in
connection with the Shelf Registration Statement, each of the Company and the Guarantors shall comply with all the provisions of Section 6(c) hereof and shall use their reasonable best efforts to effect such registration to permit the sale of
the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto each of the Company and the Guarantors will as expeditiously as possible prepare and file with the
Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of
distribution thereof. 
 (c) General Provisions. In connection with any Registration Statement and any Prospectus required
by this Agreement to permit the sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Transfer Restricted Securities by Broker-Dealers),
each of the Company and the Guarantors shall: 
 (i) use their reasonable best efforts to keep such Registration Statement
continuously effective and provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors) for the period specified in Section 3 or 4 hereof, as
applicable; upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of
Transfer Restricted Securities during the period required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, if
Commission review is required, use their reasonable best efforts to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purpose(s) as soon as practicable
thereafter; 
 (ii) use their reasonable best efforts to prepare and file with the Commission such amendments and post-effective
amendments to the applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all
Transfer Restricted Securities covered by such Registration Statement have been sold; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act,
and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration
Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus; 

  
 8 

 (iii) advise each Holder whose Transfer Restricted Securities have been included in a Shelf
Registration Statement, (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become
effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or
the initiation of any proceeding for any of the preceding purposes, (D) of the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto, or any
document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus in order to make the statements therein not misleading. If at any time the Commission shall
issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer
Restricted Securities under state securities or blue sky laws, each of the Company and the Guarantors shall use their reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time; 

(iv) in the case of a Shelf Registration Statement, furnish without charge, upon request, to each selling Holder named in any
Registration Statement, and each of the underwriter(s), if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or
Prospectus (including all documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders and underwriter(s) in connection with such sale, if
any, for a period of at least three Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated
by reference) to which a Holder of Transfer Restricted Securities covered by such Registration Statement or the underwriter(s), if any, shall reasonably object in writing within three Business Days after the receipt thereof (such objection to be
deemed timely made upon confirmation of telecopy transmission within such period). The objection of a Holder or underwriter, if any, shall be deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement, as applicable,
as proposed to be filed, contains a material misstatement or omission. Notwithstanding the foregoing, the Company shall not be required to take any actions under this Section 6(c)(iv) that are not, in the reasonable opinion of counsel for
the Company, in compliance with applicable law; 
 (v) [reserved] 

  
 9 

 (vi) in the case of a Shelf Registration Statement, make available at reasonable times for
inspection by the selling Holders, the managing underwriter(s), if any, participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such selling Holder or any of the underwriter(s), all
financial and other records, pertinent corporate documents and properties of each of the Company and the Guarantors and cause the Company’s and the Guarantors’ officers, directors and employees to supply all information reasonably
requested by any such Holder, underwriter, attorney or accountant in connection with such Registration Statement or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness and to participate in meetings
with investors to the extent requested by the managing underwriter(s), if any; provided that any Holder or representative thereof requesting or receiving such information shall agree to be bound by reasonable confidentiality agreements and
procedures with respect thereto; 
 (vii) in the case of a Shelf Registration Statement, if requested by any selling Holders or
the underwriter(s), if any, promptly incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably
request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities
being sold to such underwriter(s), the purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or
post-effective amendment as soon as practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 
 (viii) in the case of a Shelf Registration Statement, upon request, furnish to each selling Holder and each of the underwriter(s), if any, without charge, at least one copy of the Registration Statement,
as first filed with the Commission, and of each amendment thereto, including financial statements and schedules (without all documents incorporated by reference therein or exhibits thereto, unless requested); 

(ix) in the case of a Shelf Registration Statement, upon request, deliver to each selling Holder and each of the underwriter(s), if any,
without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; provided, that if no Registration Statement is effective or no Prospectus
is usable in accordance with the provisions of Section 6(b) hereof, the Company shall deliver to each selling Holder a notice to that effect in response to such request; each of the Company and the Guarantors hereby consents to the use (in
accordance with law) of the Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in connection with the offering and the sale of the Transfer Restricted Securities covered by the
Prospectus or any amendment or supplement thereto; 
 (x) in the case of a Shelf Registration Statement, upon the reasonable
request of such Holder, enter into such agreements (including an underwriting agreement containing customary terms), and make such representations and warranties, and take all such other actions in connection therewith in order to expedite or
facilitate the disposition of 

  
 10 

 
the Transfer Restricted Securities pursuant to any Registration Statement contemplated by this Agreement, all to such extent as may be customarily and reasonably requested by any Holder or
Holders of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to any Registration Statement contemplated by this Agreement; and whether or not an underwriting agreement is entered into and whether or not the
registration is an Underwritten Registration, each of the Company and the Guarantors shall: 
 (A) upon the
request of any Holder, furnish to each selling Holder and each underwriter, if any, in such substance and scope as they may reasonably request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the date of
the effectiveness of the Shelf Registration Statement: 
 (1) a certificate in customary form, dated the date of
effectiveness of the Shelf Registration Statement, as the case may be, signed by (y) the Chief Executive Officer or any Vice President and (z) a principal financial or accounting officer of the Company and such Guarantor, confirming, as of
the date thereof, the matters set forth in Section 6(c) of the Purchase Agreements and such other matters as such parties may reasonably request; 
 (2) an opinion in customary form, dated the date of the effectiveness of the Shelf Registration Statement of counsel for the Company and the Guarantors, covering the matters customarily covered in
opinions in similar underwritten offerings and such other matters as such parties may reasonably request; and 

(3) use reasonable best efforts to obtain a customary comfort letter, dated the date of effectiveness of the Shelf
Registration Statement, from the Company’s independent accountants, in the customary form and covering matters of the type customarily requested to be covered in comfort letters by underwriters in connection with primary underwritten offerings;

 (B) deliver such other documents and certificates as may be reasonably requested by such parties to evidence
compliance with Section 6(c)(x)(A) hereof and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company or any of the Guarantors pursuant to this Section 6(c)(x), if any.

 (xi) prior to any public offering of Transfer Restricted Securities, cooperate with the selling Holders, the underwriter(s),
if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the state securities or blue sky laws of such jurisdictions as the selling Holders or underwriter(s), if any, may
request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that none of
the Company nor the Guarantors shall be required to register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to
matters and transactions relating to the Registration Statement, in any jurisdiction where it is not then so subject; 

  
 11 

 (xii) shall issue, upon the request of any Holder of Transfer Restricted Securities covered
by the Shelf Registration Statement, Exchange Securities having an aggregate principal amount equal to the aggregate principal amount of Transfer Restricted Securities being sold by such Holder, such Exchange Securities to be registered in the name
of the purchaser(s) of such Securities, as the case may be, and in return, the Transfer Restricted Securities held by such Holder shall be surrendered to the Company for cancellation; 

(xiii) cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the
underwriter(s), if any, may request at least three Business Days prior to any sale of Transfer Restricted Securities made by such Holders or underwriter(s); 
 (xiv) use their reasonable best efforts to cause the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or
authorities as may be necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in Section 6(c)(xii) hereof;

 (xv) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement
or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted
Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading; 

(xvi) provide a CUSIP number for all Securities not later than the effective date of the Registration Statement covering such Securities
and provide the Trustee under the Indenture with printed certificates for such Securities which are in a form eligible for deposit with the Depository Trust Company and take all other action necessary to ensure that all such Securities are eligible
for deposit with the Depository Trust Company; 
 (xvii) cooperate and assist in any filings required to be made with FINRA and
in the performance of any due diligence investigation by any underwriter (including any “qualified independent underwriter”) that is required to be retained in accordance with the rules and regulations of FINRA; 

(xviii) otherwise use their reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make
generally available to its security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 under the Securities Act (which need not be audited) for the twelve-month period commencing after the
effective date of the Registration Statement; 

  
 12 

 (xix) cause the Indenture to be qualified under the Trust Indenture Act not later than the
effective date of the first Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the Holders of Securities to effect such changes to the Indenture as may be required for such Indenture to be
so qualified in accordance with the terms of the Trust Indenture Act; and to execute and use its reasonable best efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents
required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner; and 
 (xx) provide
promptly to each Holder upon request each document filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act, unless such document is available through the Commission’s EDGAR and/or IDEA
system. 
 (d) Restrictions on Holders. Each Holder agrees by acquisition of a Transfer Restricted Security that, upon
receipt of the notice referred to in Section 6(c)(iii)(C) or any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof (in each case, a “Suspension Notice”), such Holder
will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until (i) such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 6(c)(xv) hereof, or (ii) it is advised in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are
incorporated by reference in the Prospectus. Each Holder receiving a Suspension Notice hereby agrees that it will either (i) destroy any Prospectuses, other than permanent file copies, then in such Holder’s possession which have been
replaced by the Company with more recently dated Prospectuses, or (ii) deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such
Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Company shall give any such notice, the time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4
hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such
Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xv) hereof or shall have received the Advice; provided, however, that no such extension shall be
taken into account in determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such Additional Interest, it being agreed that the Company’s option to suspend use of a Registration Statement pursuant to
this paragraph shall be treated as a Registration Default for purposes of Section 5 hereof. 
 Section 7.
Registration Expenses. 
 (a) All expenses incident to the Company’s and the Guarantors’ performance of or
compliance with this Agreement will be borne by the Company and the Guarantors, jointly and severally, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and
expenses (including filings made by any Holder with FINRA); (ii) all fees and expenses of compliance 

  
 13 

 
with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer
and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company and the Guarantors; and (v) all fees and disbursements of independent certified public accountants of
the Company and the Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance). 
 Each of the Company and the Guarantors will, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting
duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company or the Guarantors. 
 (b) In connection with any Registration Statement required by this Agreement (including, without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company
and the Guarantors, jointly and severally, will reimburse the Holders of Transfer Restricted Securities being tendered in the Exchange Offer and/or resold pursuant to the “Plan of Distribution” contained in the Exchange Offer Registration
Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable and documented fees and disbursements of Paul, Weiss, Rifkind, Wharton & Garrison LLP, counsel for the Holders of a majority in
principal amount of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared. 

Section 8. Indemnification. 
 (a) The Company and the Guarantors agree, jointly and severally, to indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective officers, directors,
partners, employees, representatives and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an “Indemnified Holder”), to the fullest extent
lawful, from and against any and all losses, claims, damages, liabilities, judgments, actions and expenses (including, without limitation, and as incurred, reimbursement of all reasonable out-of-pocket costs of investigating, preparing, pursuing,
settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any Indemnified Holder), joint
or several, directly or indirectly caused by, related to, based upon, arising out of or in connection with any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or
supplement thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or
expenses are caused by an untrue statement or omission or alleged untrue statement or omission that is based upon information relating to any of the Holders furnished in writing to the Company by or on behalf of the Holders expressly for use
therein. This indemnity agreement shall be in addition to any liability which the Company or any of the Guarantors may otherwise have. 

  
 14 

 In case any action or proceeding (including any governmental or regulatory investigation or
proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to which indemnity may be sought against the Company or the Guarantors, such Indemnified Holder (or the Indemnified Holder controlled by such controlling
person) shall promptly notify the Company and the Guarantors in writing; provided, however, that the failure to give such notice shall not relieve any of the Company or the Guarantors of its obligations pursuant to this Agreement
except to the extent that it had been materially prejudiced by such failure. Such Indemnified Holder shall have the right to employ its own counsel in any such action and the fees and expenses of such counsel shall be paid, as incurred, by the
Company and the Guarantors. The Company and the Guarantors shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be designated by the
Holders. The Company and the Guarantors shall be liable for any settlement of any such action or proceeding effected with the Company’s and the Guarantors’ prior written consent, which consent shall not be withheld unreasonably, and each
of the Company and the Guarantors agrees to indemnify and hold harmless any Indemnified Holder from and against any loss, claim, damage, liability or reasonable out-of-pocket expense by reason of any settlement of any action effected with the
written consent of the Company and the Guarantors. The Company and the Guarantors shall not, without the prior written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any
pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or
termination (i) includes an unconditional release of each Indemnified Holder from all liability arising out of such action, claim, litigation or proceeding and (ii) does not include a statement as to an admission of fault, culpability or a
failure to act, by or on behalf of the Indemnified Holder. 
 (b) By its acquisition of Transfer Restricted Securities each
Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors and their respective directors and officers of the Company and the Guarantors who sign a Registration Statement,
and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company or any of the Guarantors, and the respective officers, directors, partners, employees, representatives and
agents of each such Person, to the same extent as the foregoing indemnity from the Company and the Guarantors to each of the Indemnified Holders, but only with respect to claims and actions based on information relating to such Holder furnished in
writing by such Holder expressly for use in any Registration Statement. In case any action or proceeding shall be brought against the Company, the Guarantors or their respective directors or officers or any such controlling person in respect of
which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall have the rights and duties given the Company and the Guarantors, and the Company, the Guarantors, their respective directors and officers and such
controlling person shall have the rights and duties given to each Holder by the preceding paragraph. 

  
 15 

 (c) If the indemnification provided for in this Section 8 is unavailable to an
indemnified party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or expenses referred to therein, then each
applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is
appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Holders, on the other hand, from the Initial Issuance (which in the case of the Company and the Guarantors shall be deemed to be equal
to the total gross proceeds to the Company and the Guarantors from the Initial Issuance), the amount of Additional Interest which did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims,
damages, liabilities, judgments actions or expenses, or if such allocation is not permitted by applicable law, the relative fault of the Company and the Guarantors, on the one hand, and the Holders, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Indemnified Holder, on the other
hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any of
the Guarantors, on the one hand, or the Indemnified Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other fees or expenses
reasonably incurred by such party in connection with investigating or defending any action or claim. 
 The Company, the
Guarantors and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for
such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the
amount by which the total discount received by such Holder with respect to the Initial Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The
Holders’ obligations to contribute pursuant to this Section 8(c) are several in proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint. 

  
 16 

 Section 9. Participation in Underwritten Registrations. No Holder may
participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to
approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

 Section 10. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf
Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will administer such offering will be
selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment banker(s) and managing underwriter(s) must be reasonably
satisfactory to the Company. 
 Section 11. Miscellaneous. 

(a) No Inconsistent Agreements. Each of the Company and the Guarantors will not on or after the date of this Agreement enter into
any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Neither the Company nor any of the Guarantors has previously entered into
any agreement granting any registration rights with respect to its securities to any Person. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the
Company’s or any of the Guarantors’ securities under any agreement in effect on the date hereof. 
 (b) Amendments
and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 5 hereof
and this Section 11(c)(i), obtained the written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the
outstanding principal amount of Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such
Exchange Offer may be given by the Holders of a majority of the outstanding principal amount of Transfer Restricted Securities being tendered or registered. 
 (c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt
requested), telex, telecopier, or air courier guaranteeing overnight delivery:

for an express assignment, subsequent Holders of Transfer Restricted Securities; provided, however, that this Agreement shall not inure to the benefit of or be binding upon a successor or assign of a Holder unless and to the extent
such successor or assign acquired Transfer Restricted Securities from such Holder. 
 (e) Counterparts. This Agreement

herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be
affected or impaired thereby.

their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other
than those set forth or referred to herein with respect to the registration rights granted by the Company with respect to the Transfer Restricted Securities. This Agreement supersedes all prior agreements and understandings between the parties with
respect to such subject matter.
