(a) Subject to Section 2.3(b), Pledgor hereby pledges and assigns to the Collateral Agent, for the ratable benefit of the Secured
Parties, and grants to the Collateral Agent, its successors and assigns, for the ratable benefit of the Secured Parties, a Lien upon and security interest in, all of Pledgor’s right, title and interest in and to the following, in each case
whether now owned or existing or hereafter acquired or arising or in which Pledgor now has or at any time in the future may acquire any right, title or interest (it being understood that, subject to Section 2.3(b),
Section 2.3(c) and Section 1.2, the following assets and properties shall also constitute “Collateral” as used in this Agreement): 

(i) all Copyright Collateral; 

(ii) all Patent Collateral; 

(iii) all Trademark Collateral; and 

(iv) any and all proceeds, as such term is defined in the Uniform Commercial Code, products, rents and profits of or from any
and all of the foregoing and, to the extent not otherwise included in the foregoing, (w) all payments under any insurance (whether or not the Trustee or the Collateral Agent is the loss payee thereunder), indemnity, warranty or guaranty with
respect to any of the foregoing Collateral, (x) all payments in connection with any requisition, condemnation, seizure or forfeiture with respect to any of the foregoing Collateral, (y) all claims and rights to recover for any past,

(b) Notwithstanding the provisions of Section 2.3(a) or any of the provisions contained herein or in the Indenture or Notes, no
Lien upon and security interest in the Deferred Interests shall be deemed to have occurred nor shall any such Lien and security interest be deemed to have attached to or on the Deferred Interests until any of the following events shall have occurred
(each a “Deferred Interests Triggering Event”): (i) Deferred Interests shall be pledged to the holders of such Designated Senior Claim or a representative on their behalf to secure a Designated Senior Claim, or (ii) an
Event of Default shall have occurred and be continuing. Immediately upon the occurrence of any Deferred Interests Triggering Event, a Lien on the Deferred Interests consisting of Copyright Collateral, Patent Collateral, Trademark Collateral and all
Proceeds related thereto shall automatically be deemed to have attached in favor of the Collateral Agent pursuant to this Section 2.3 without any further action by the Collateral Agent or Pledgor and, on and after the occurrence of such
Deferred Interests Triggering Event, the Pledgor shall file financing statements under the Uniform Commercial Code describing the Collateral represented by such Deferred Interests and Pledgor shall take all necessary actions, including, but not

Interests Triggering Event) at Pledgor’s expense in order to give the Collateral Agent a first priority security interest (subject to Permitted Liens) in the Collateral represented by such Deferred Interests. As of the date on which a Lien on
any Deferred Interests attaches pursuant to this Section 2.3, the Pledgor shall be deemed to have reaffirmed the representations and warranties set forth in Article III with respect to such Deferred Interests. Notwithstanding anything to
the contrary set forth herein, with respect to any Patent Collateral, no Lien or security interest in favor of the Collateral Agent shall attach or be deemed to attach, and Collateral Agent agrees not to take any action to register, record or file
any financing statement or other evidence of a Lien or security interest, without the prior written consent of the Pledgor (except that no such consent shall be required if a bankruptcy or insolvency proceeding shall have been commenced by or
against Pledgor) if: (i) the attachment, registration, recordation or filing of such Lien could reasonably be expected to (x) result in a breach or violation of any of the terms or provisions of any license, permit or contractual agreement
between Pledgor and the DOE or any other applicable governmental authority or (y) limit, invalidate or impair Pledgor’s right to maintain ownership of or license or right to use, such Patent Collateral; or (ii) such Patent Collateral
includes classified information and the attachment, registration, recordation or filing of such Lien on such Patent Collateral would constitute a breach or violation of Pledgor’s duty to maintain the confidentiality of such classified
information. 

  
 8 

 (c) Without limiting Section 1.2, in no event shall the Collateral include, and
Pledgor shall not be deemed to have granted a security interest in any of Pledgor’s rights or interests in, any license, contract or agreement to which Pledgor is a party or any of its or interests thereunder to the extent, but only to the
extent, that such a grant would, under the terms of such license, contract or agreement or otherwise, result in a breach of the terms of, or constitute a default under any such license, contract or agreement (other than to the extent that any such
term would be rendered ineffective pursuant to the Uniform Commercial Code or any other applicable law (including the Bankruptcy Code) or principles of equity); provided that immediately upon the ineffectiveness, lapse or termination of any
such term, the Collateral shall include, and Pledgor shall be deemed to have granted a security interest in, all such rights and interests as if such term had never been in effect; provided further that any Account or money or other amounts
due or to become due to Pledgor under any such license, contract or agreement or any proceeds resulting from the sale or other disposition by Pledgor of any rights of Pledgor under any such license, contract or agreement shall at no time be excluded
from the Collateral or the security interest granted by Pledgor hereunder in favor of the Collateral Agent. 
 (d) Except as specifically
provided herein or as permitted by the Indenture, Pledgor will not sell or otherwise dispose of, grant any option with respect to, or grant any Lien with respect to or otherwise encumber any of the Deferred Interests or any interest therein;
provided that a Lien on Deferred Interests may be granted to secure Designated Senior Claims so long the Collateral Agent also has a Lien on any and all Deferred Interests securing any Designated Senior Claim. 

2.4 Inventory Account. Pledgor shall establish, in its own name, an Inventory Account to which all Pledgor-owned uranium and SWU

3.2 Security Interests; Filings. This Agreement, together with (i) the filing of duly completed and authorized Uniform Commercial
Code financing statements (A) naming Pledgor as debtor, (B) naming the Collateral Agent as secured party, and (C) describing the Collateral, in the jurisdictions set forth with respect to Pledgor on Annex B hereto,
(ii) when the Lien on the Deferred Interests attaches pursuant hereto, the filing of duly completed and executed assignments in the forms set forth as Exhibits B, C and D with the U.S. Copyright Office or the U.S. Patent
and Trademark Office, and, as appropriate, with regard to federally registered Copyright Collateral, Patent Collateral and Trademark Collateral of Pledgor, as the case may be, (iii) to the extent required hereunder, the physical delivery to the
Collateral Agent of all certificated securities and Instruments included in the Collateral together with undated stock powers or instruments of transfer duly executed in blank and (iv) the entering into of “control agreements” with
respect to each Deposit Account and Securities Account to the extent required hereunder, creates, and at all times shall constitute, a valid and perfected security interest in and Lien upon the Collateral that

  
 9 

 
can be perfected by the filing of financing statements under the UCC, or that have been so delivered, or as to which such “control” has been obtained, in each case, in favor of the
Collateral Agent, for the benefit of the Secured Parties, to the extent that Articles 8 and 9 of the Uniform Commercial Code are applicable thereto, superior and prior to the rights of all other persons therein (except for Permitted Liens), and no
other or additional filings, registrations, recordings or actions are or shall be necessary or appropriate in order to perfect or maintain the perfection and priority of such Lien and security interest, other than actions required with respect to
Collateral of the types excluded from Articles 8 or 9 of the Uniform Commercial Code or from the filing requirements under Article 9 of the Uniform Commercial Code by reason of Sections 9-309, 9-310, 9-311 and 9-312 of the Uniform Commercial Code
and other than continuation statements required under the Uniform Commercial Code. None of the Equipment is covered by any certificate of title, except for Equipment consisting of motor vehicles. Notwithstanding the foregoing or any other provision
of this Agreement, no action need be taken to create, perfect or otherwise protect the security interest under any foreign (i.e. non-U.S.) law. 

3.3 Locations. Annex C lists, as to Pledgor, (i) the addresses of its chief executive office, each other place of
business, its state of incorporation and organizational I.D. number, (ii) the address of each location where all original invoices, ledgers, chattel paper, Instruments and other records or information evidencing or relating to the Collateral of
Pledgor are maintained, and (iii) the address of each location at which any Inventory or Equipment owned by Pledgor is kept or maintained, in each instance except for any new locations established in accordance with the provisions of
Section 4.2 and except for Inventory and Equipment which, in the ordinary course of business, is in transit (A) from a supplier to Pledgor or to a location listed on Annex C, (B) between locations listed on Annex C, or
(C) to processors or a location listed on Annex C. Except as may be otherwise noted therein, all locations identified in Annex C are leased by the Pledgor or Pledgor has an agreement with the operator thereof to hold Inventory or
Equipment on behalf of Pledgor, including pending delivery to a customer. Pledgor does not presently conduct business under any prior or other corporate or company name or under any trade or fictitious names, except as indicated beneath its name on
Annex C, and Pledgor has not entered into any contract or granted any Lien within the past five (5) years under any name other than its legal name or a trade or fictitious name indicated on Annex C. Each trade or fictitious name
is a trade name and style (and not the name of an independent corporation or other legal entity) by which Pledgor may identify and sell certain of its goods or services and conduct a portion of its business; all related Accounts are owned solely by
the Pledgor and are subject to the Liens and other terms of this Agreement; and in no event shall Pledgor assert that products invoiced under the name of any trade or fictitious name that are subject to a dispute with Customers are not subject to
the terms of this Agreement as though such trade or fictitious name did not exist. 
 3.4 Authorization; Consent. No
authorization, consent or approval of, or declaration or filing with, any Governmental Authority (including, without limitation, any notice filing with state tax or revenue authorities required to be made by account creditors in order to enforce any
Accounts in such state) is required for the valid execution, delivery and performance by Pledgor of this Agreement, the grant by it of the Lien and security interest in favor of the Collateral Agent provided for herein, or the exercise by the
Collateral Agent, in accordance with the Intercreditor Agreement and Security Documents, of its rights and remedies hereunder, except for (i) the filings and actions described in Section 3.2, (ii) in the case of Accounts owing
from any federal governmental agency or authority, compliance with the federal Assignment of Claims Act of 1940, as amended, (iii) in the case of Equity Interests, such filings and approvals as may be required in connection with a disposition
of any such Collateral by laws affecting the offering and sale of securities generally, (iv) consents and approvals, if any, required from the Department of Energy in its capacity as owner of the plants at which Collateral is located in
connection with the exercise of remedies hereunder under circumstances where the Pledgor does not remain in control of such plants or in control of the portion of such plants where Collateral is located, and (v) the other consents and approvals
described in Section 8.15. The provisions of this Section 3.4 shall not apply to any Collateral located outside of the United States. Nothing in this Agreement shall be construed to require or authorize the Collateral Agent to
comply with the federal Assignment of Claims Act. 
 3.5 No Restrictions. There are no statutory or regulatory restrictions,
prohibitions or limitations on Pledgor’s ability to grant to the Collateral Agent a Lien upon and security interest in the Collateral (including without limitation, all Deferred Interests which would become Collateral if a Deferred Interests
Triggering Event were to occur) pursuant to this Agreement or (except for the provisions of the federal Assignment of Claims Act of 1940, as amended, or applicable regulatory limitations on access to U.S. Government-owned facilities) the exercise

  
 10 

 
by the Collateral Agent, in accordance with the Intercreditor Agreement and Security Documents, of its rights and remedies hereunder (including any foreclosure upon or collection of the
Collateral) except for the restrictions described in Section 8.15 or Section 1.2, and there are no contractual restrictions, prohibitions or limitations on Pledgor’s ability so to grant such Lien and security interest or on the
exercise by the Collateral Agent, in accordance with the Intercreditor Agreement and Security Documents, of its rights and remedies hereunder (including any foreclosure upon or collection of the Collateral). 

3.6 Equity Interests. The Pledgor has no subsidiaries. 

3.7 Intellectual Property. Concurrently with the execution and delivery of this Agreement by the Pledgor, the Pledgor has delivered to
the Collateral Agent a schedule of material Copyrights, Patents and Trademarks, which schedule correctly sets forth all material registered Copyrights, Patents and Trademarks owned by the Pledgor (other than Copyrights, Patents and Trademarks, the
subject matter of which is “classified” for reasons of national security or foreign policy) as of the date hereof. As of date on which the Lien on the Deferred Interests attaches pursuant hereto, Annexes D, E and F
correctly set forth all registered Copyrights, Patents and Trademarks owned by Pledgor as of the date thereof and used or proposed to be used in its business. Except to the extent set forth on Schedule I hereto, as of the date hereof and as of the
date on which the Lien on such Deferred Interests attaches, Pledgor owns or possesses the valid right to use all Copyrights, Patents and Trademarks material to its business and, to the best of Pledgor’s knowledge, the use thereof by the Pledgor
does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. As of the date hereof and as of the date on which
the Lien on the Deferred Interests attaches, all Copyrights, Patents and Trademarks (a) have been duly registered in, filed in or issued by the U.S. Copyright Office, United States Patent and Trademark Office or other corresponding offices of
other applicable jurisdictions, where such registration or filing is commercially reasonable, the subject matter of the Copyright, Patent or Trademark is not “classified” for reasons of national security or foreign policy, and registration
and filing is permitted by applicable law or regulation, and (b) have been properly maintained and renewed in accordance with all applicable provisions of law and administrative regulations in the United States or in each such other
jurisdiction, as applicable, except, in each case, for such Patents, Trademarks or Copyrights which, as reasonably determined by the Pledgor consistent with prudent and commercially reasonable business practices (x) are not material to the
business of the Pledgor or (y) the Pledgor has abandoned prior to the date on which the Lien on such Deferred Interests attaches. 

3.8 Documents of Title. No material bill of lading, warehouse receipt or other document or instrument of title is outstanding with
respect to any Collateral other than Inventory or Equipment in transit in the ordinary course of business to a location set forth on Annex C or to or from a supplier or a customer of Pledgor, or to or from a fabricator or other nuclear fuel
processor or a storage facility. 
 3.9 Deposit Accounts and Securities Accounts. Annex G correctly sets forth all Deposit
Accounts and Securities Accounts of Pledgor. Other than any Excluded Accounts, each Deposit Account is subject to a deposit account control agreement and each Securities Account is subject to a securities account control agreement (subject to
Section 3.2 and 8.16 hereof). 
 ARTICLE IV 

COVENANTS

Disposition of Collateral. So long as no Event of Default shall have occurred and be continuing, Pledgor may, in any lawful manner not inconsistent with the provisions of this Agreement and the Indenture, use, control and manage the Collateral
in the operation of its businesses, and receive and use the income, revenue and profits arising therefrom and the Proceeds thereof, in the same manner and with the same effect as if this Agreement had not been made; provided, however,
that Pledgor will not sell or otherwise dispose of, grant any option with respect to, or grant any Lien with respect to or otherwise encumber any of the Collateral or any interest therein, except for the security interest created in favor of the
Collateral Agent hereunder and except as may be otherwise expressly permitted in accordance with the terms of either this Agreement or the Indenture (including any applicable provisions therein regarding delivery of proceeds of sale or disposition

transit), or any books, records or other information relating to Collateral, from the applicable location thereof listed on Annex C or as described in Section 3.3, or keep or maintain any Collateral (other than goods in transit) at a
location not listed on Annex C or described in Section 3.3, unless in each case Pledgor has (A) given fifteen (15) days’ prior written notice to the Collateral Agent of its intention to do so, together with information
regarding any such new location and such other information in connection with such proposed action as the Collateral Agent may (but has no duty to) reasonably request, and (B) delivered to the Collateral Agent via email fifteen (15) days
prior to any such change or removal of such documents, instruments and financing statements as may be required under applicable law, and the Collateral Agent has had a reasonable chance to review such documents, instruments and financing statements,
paid all necessary filing and recording fees and taxes, in order to perfect and maintain the Lien upon and security interest in the Collateral provided for herein in accordance with the provisions of Section 3.2, delivered an
Officers’ Certificate (as defined in the Indenture) certifying the facts of such changes, and taken all other actions reasonably requested by the Collateral Agent (provided that delivery of an opinion of counsel may only be requested where
required by the Indenture). 
 4.3 Records; Inspection. 

(a) Pledgor will keep and maintain at its own cost and expense satisfactory and complete records of the Accounts and all other Collateral,
including, without limitation, records of all payments received, all credits granted thereon, all merchandise returned and all other documentation relating thereto, and will furnish to the Collateral Agent such statements, schedules and reports
(including, without limitation, accounts receivable aging schedules) with regard to the Collateral or from time to time, as the Collateral Agent may reasonably request. 

(b) Pledgor shall, from time to time at such times as may be reasonably requested and upon reasonable notice, make available to the
Collateral Agent for inspection and review at Pledgor’s offices copies of all invoices and other documents and information relating to the Collateral (including, without limitation, itemized schedules of all collections of Accounts, showing the
name of each account debtor, the amount of each payment and any such other information, if any, as the Collateral Agent shall reasonably request); provided, that Collateral Agent agrees to maintain the confidentiality of such information on terms
reasonably acceptable to the Pledgor and provided further that Pledgor shall not be obligated to provide any information that is “classified” for reasons of national security or foreign policy or otherwise restricted from disclosure under
applicable laws or agreements. 
 4.4 Instruments. Pledgor agrees that if any Collateral shall at any time be evidenced by a
promissory note, tangible Chattel Paper or other Instrument (other than checks or other Instruments for deposit in the ordinary course of business), subject to the Intercreditor Agreement, the same shall promptly be duly endorsed to the order of the
Collateral Agent and physically delivered to the Collateral Agent to be held as Collateral hereunder. 
 4.5 Inventory and Equipment.
Pledgor will, in accordance with sound business practices, maintain all Equipment and Eligible Inventory held by it or on its behalf in good repair and working and saleable or useable condition, except for ordinary wear and tear in respect of the
Equipment; provided, that the foregoing shall not restrict or prohibit the Paducah Transition or the transactions contemplated by the ACP Grant. Unless an Event of Default has occurred and is continuing and the Pledgor has knowledge thereof, Pledgor
may, in any lawful manner not inconsistent with the provisions of this Agreement and the Indenture, process, use, ship, deliver and, in the ordinary course of business or as otherwise permitted under the Indenture, sell, transfer, lease or otherwise
dispose of its Inventory or Equipment. Pledgor further agrees that its Inventory will be produced in compliance with the applicable requirements of the Fair Labor Standards Act, as amended, if such Inventory is produced by Pledgor at a facility
operated by Pledgor in the United States. No Pledgor will, without the Collateral Agent’s prior written consent, alter or remove any identifying symbol or number on any of Pledgor’s Equipment constituting Collateral except pursuant to a
sale of such Collateral to a third party permitted by this Agreement or the Indenture. 

  
 12 

 4.6 Taxes. Pledgor will, to the extent required under Section 4.05 of the Indenture,
pay and discharge (i) all taxes, assessments and governmental charges or levies imposed upon it, upon its income or profits or upon any of its properties, prior to the date on which penalties would attach thereto, and (ii) all lawful
claims for taxes, assessment, governmental charges or levies that, if unpaid, might become a Lien upon any of the Collateral. 
 4.7
Insurance. 
 (a) Pledgor will maintain and pay for, or cause to be maintained and paid for, with responsible insurance companies,
insurance with respect to its assets, properties and business, against such hazards and liabilities, of such types and in such amounts, as is required pursuant to Section 4.12 of the Indenture. 

(b) Pledgor hereby irrevocably makes, constitutes and appoints the Collateral Agent at all times during the continuance of an Event of
Default, its true and lawful attorney (and agent-in-fact) for the purpose of making, settling and adjusting claims under such policies of insurance, endorsing its name on any check, draft, instrument or other item or payment for the proceeds of such
policies of insurance and for making all determinations and decisions with respect to such policies of insurance. 
 (c) If Pledgor fails
to obtain and maintain any of the policies of insurance required to be maintained hereunder or to pay any premium in whole or in part, the Collateral Agent may, without waiving or releasing any obligation or Default, at Pledgor’s expense, but
without any obligation to do so, procure such policies or pay such premiums. All sums so disbursed by the Collateral Agent, including reasonable attorneys’ fees, court and out of pocket costs, expenses and other charges related thereto, shall
be payable by the Pledgor to the Collateral Agent on demand and shall be additional Secured Obligations hereunder, secured by the Collateral. 

(d) Pledgor will deliver to the Collateral Agent, promptly as rendered, true copies of all material claims and reports made in any reporting
forms to insurance companies. Pledgor will deliver to the Collateral Agent one or more certificates of insurance evidencing renewal of the insurance coverage required hereunder (or issuance of a replacement policy from another insurance company
meeting the requirements of this Section 4.7) plus such other evidence of payment of premiums therefor as the Collateral Agent may request. Upon the reasonable request of the Collateral Agent, from time to time, Pledgor will deliver to
the Collateral Agent evidence that the insurance required to be maintained pursuant to this Section is in effect. 
 4.8 Intellectual
Property. 
 (a) If at any time a Credit Agreement is outstanding and such Credit Agreement requires that the Pledgor deliver an
updated schedule of material Copyrights, Patents and Trademarks to the Credit Agreement Agent, then whenever the Pledgor so delivers such an updated schedule to the Credit Agreement Agent, it shall also deliver the copies of such updated schedules
to the Collateral Agent. If there is no Credit Agreement outstanding or such Credit Agreement does not require that the Pledgor deliver updated schedules of material Copyrights, Patents and Trademarks periodically, then the Pledgor shall nonetheless
deliver updated schedules of Copyrights, Patents and Trademarks included in the Collateral not less frequently than once per calendar year commencing on the first anniversary date of the Deferred Interest Triggering Event and, if an Event of Default
shall have occurred and be continuing, updated schedules will be delivered to the Collateral Agent. As of the date on which the Lien on the Deferred Interests attaches, Pledgor will, at its own expense, execute and deliver a fully completed
Copyright Security Agreement, Patent Security Agreement or Trademark Security Agreement in the respective forms of Exhibits B, C and D, as applicable, with regard to any Copyright Collateral, Patent Collateral or Trademark
Collateral (in each case, to the extent registered or filed, subject to the provisions of Section 3.7 hereof), as the case may be, of Pledgor, described in Annexes D, E and F hereto. In the event that after such
date, Pledgor shall acquire any registered Copyright Collateral, Patent Collateral or Trademark Collateral or effect any registration of any such Copyright Collateral, Patent Collateral or Trademark Collateral or file any application for
registration thereof, within the United States, Pledgor shall promptly furnish written notice thereof to the Collateral Agent together with information sufficient to permit the Collateral Agent, upon its receipt of such notice, to (and Pledgor
hereby authorizes the Collateral Agent to) modify this Agreement, as appropriate, by amending Annex D, E or F hereto or to add additional exhibits hereto to include any Copyright Collateral, Patent Collateral or Trademark
Collateral (in each case, to the extent registered or filed, subject to the provisions of Section 3.7 hereof) that becomes part of the 

  
 13 

 
Collateral under this Agreement, and Pledgor shall additionally, at its own expense, execute and deliver, as promptly as possible (but in any event within ten (10) days) after the date of
such notice, with regard to United States Copyrights, Patents and Trademarks, fully completed Copyright Security Agreements, Patent Security Agreements or Trademark Security Agreements in the forms of Exhibits B, C and D,
as applicable, together in all instances with any other agreements, instruments and documents that the Collateral Agent may reasonably request from time to time to further effect and confirm the security interest created by this Agreement in such
Copyright Collateral, Patent Collateral and Trademark Collateral, and Pledgor hereby appoints the Collateral Agent its attorney-in-fact, upon the occurrence and the continuance of an Event of Default, to execute, deliver and record any and all such
agreements, instruments and documents for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed and such power, being coupled with an interest, being irrevocable for so long as this Agreement shall be in effect with
respect to Pledgor. In that connection, Pledgor shall also execute and deliver on the date on which the Lien on the Deferred Interests attaches, one copy of the Special Power of Attorney in the form of Annex H hereto. 

(b) The Pledgor shall file and prosecute diligently all applications for registration of Patents, Trademarks or Copyrights now or hereafter
pending that would be necessary to the business of the Pledgor to which any such applications pertain, and do all acts (or refrain from doing all acts), in any such instance, reasonably necessary to preserve and maintain all material rights in
Patents, Trademarks or Copyrights, unless such Patents, Trademarks or Copyrights are not material to the business of the Pledgor, as reasonably determined by the Pledgor consistent with prudent and commercially reasonable business practices. 

(c) From and after the date on which the Lien on the Deferred Interests attaches, Pledgor shall notify the Collateral Agent promptly in
writing if it knows or has reason to know that any material Patent Collateral, Trademark Collateral or Copyright Collateral used in the conduct of its business may become abandoned or dedicated to the public, or of any adverse determination or
development (including the institution of, or any such determination or development in, any proceeding in the U.S. Patent and Trademark Office, U.S. Copyright Office or any court) regarding Pledgor’s ownership of any material Patent Collateral,
Trademark Collateral or Copyright Collateral, its right to register the same, or to keep and maintain the same. 
 (d) From and after the
date on which the Lien on the Deferred Interests attaches, in the event that any Collateral consisting of material Patent Collateral, Trademark Collateral or Copyright Collateral used in the conduct of Pledgor’s business is believed infringed,
misappropriated or diluted by a third party, Pledgor shall notify the Collateral Agent promptly in writing after it learns thereof and shall, if consistent with the exercise of reasonable business judgment and applicable laws, regulations and
agreements to which the applicable Pledgor is a party, promptly sue for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and take such other actions as are appropriate
under the circumstances to protect such Collateral. 
 (e) From and after the date on which the Lien on the Deferred Interests attaches,
upon the occurrence and during the continuance of any Event of Default, Pledgor shall use its commercially reasonable efforts to obtain all requisite consents or approvals from the licensor of each material License included within the Copyright
Collateral, Patent Collateral or Trademark Collateral to effect the assignment of all of Pledgor’s right, title and interest thereunder to the Collateral Agent or its designee. 

4.9 Delivery of Collateral. Subject to the Intercreditor Agreement and Section 8.16 hereof, all certificates or instruments
representing or evidencing any material Account, Equity Interest or other Collateral delivered to the Collateral Agent pursuant to this Agreement, shall be in form suitable for transfer by delivery and shall be delivered together with undated stock
powers duly executed in blank, appropriate endorsements or other necessary instruments of registration, transfer or assignment, duly executed, and in each case such other instruments or documents required or as the Collateral Agent may, but is not
required to, request (provided that delivery of an opinion of counsel may only be requested where required by the Indenture). Pledgor shall deliver an Officers’ Certificate (as defined in the Indenture) to the Collateral Agent certifying as to
the requirements for delivery. 

  
 14 

 4.10 Protection of Security Interest. Pledgor agrees that it will use commercially
reasonable efforts, at its own cost and expense, to take any and all actions necessary to warrant and defend the right, title and interest of the Collateral Agent and Secured Parties in and to the Collateral against the claims and demands of all
other persons. 
 4.11 Control of Investment Property, Deposit Accounts and Electronic Chattel Paper. Subject to the Intercreditor
Agreement, the last sentence of Section 3.2 and Section 8.16 hereof, if any Investment Property (whether now owned or hereafter acquired) is included in the Collateral, Pledgor will notify the Collateral Agent in writing
thereof and will promptly take and cause to be taken all actions required under Articles 8 and 9 of the Uniform Commercial Code and any other applicable law to enable the Collateral Agent (or the Credit Agreement Agent as agent or bailee for the
Collateral Agent) to acquire “control” (within the meaning of such term under Section 8-106 (or its successor provision) of the Uniform Commercial Code) of such Investment Property and as may be otherwise necessary to perfect the
security interest of the Collateral Agent therein. Subject to the Intercreditor Agreement and Section 8.16 hereof, if any Deposit Account (whether now owned or hereafter acquired), other than any Excluded Account, is included in the
Collateral, Pledgor will notify the Collateral Agent in writing thereof and will promptly take and cause to be taken all actions required under Article 9 of the Uniform Commercial Code and any other applicable law to enable the Collateral Agent to
acquire “control” (within the meaning of such term under Section 9-104 (or its successor provision) of the Uniform Commercial Code) of such Deposit Account and as may be otherwise necessary to perfect the security interest of the
Collateral Agent therein. Subject to the Intercreditor Agreement and Section 8.16 hereof, if any Account of Pledgor would constitute “electronic chattel paper” as defined under the Uniform Commercial Code, Pledgor will promptly
notify the Collateral Agent in writing and will take such other steps as may be necessary to give the Collateral Agent (or the holder of any Designated Senior Claim or a representative of such a holder, as agent or bailee for the Collateral Agent)
“control” over such electronic chattel paper (within the meaning of Section 9-105 of the Uniform Commercial Code). Notwithstanding the foregoing, the provisions of any control agreement shall provide that the Company may terminate
such control agreement by delivery of a written certification to each of the relevant deposit bank, securities intermediary, issuer or custodian, as applicable, and the Collateral Agent that the property subject to such control agreement is subject
to another control agreement for the benefit of the holders of any Designated Senior Claims or their agent or other representative who are parties to the Intercreditor Agreement (provided that the foregoing termination shall not apply to any control
agreement that established the control of both the Collateral Agent and the holders of any Designated Senior Claims so long as such control is consistent with the priorities established by the Intercreditor Agreement). The Company agrees to use
commercially reasonable efforts to cause one of the following to occur (such obligation to use commercial reasonable efforts to continue with respect to each of the following until such efforts are successful as to one of the following or such
efforts are unsuccessful as to all of the following): (i) obtain the consent of the applicable holders of Designated Senior Claims or their agent(s) or other representative(s) and the applicable deposit bank, securities intermediary, issuer or
custodian, as applicable, to the Collateral Agent retaining its own separate control agreement reflecting the priorities established by the Intercreditor Agreement, (ii) obtain the consent of the applicable holders of Designated Senior Claims
or their agent(s) or other representative(s) and the applicable deposit bank, securities intermediary, issuer or custodian, as applicable, to the Collateral Agent being a party to the control agreement in favor of the holders of Designated Senior
Claims or their agent(s) and pursuant to such control agreement having the applicable deposit bank, securities intermediary, issuer or custodian, as applicable, agree to follow instructions or entitlement orders, as applicable, of the Collateral
Agent without further consent of the Company upon a discharge of the Designated Senior Claims, or (iii) in the event that the provisions of Sections 8-106 and 9-104 of the Uniform Commercial Code are amended in a manner consistent with that set
forth in Assembly Bill 9933, cause any control agreement for the benefit of any holders of Designated Senior Claims to be subject to the Uniform Commercial Code. The Company agrees that it will not exercise its right to terminate any such separate
control agreements in favor of the Collateral Agent so long as the consent referred to in clause (i) is obtained or if such separate control agreement is amended in accordance with clause (ii) rather than replaced. 

4.12 Supplements to Schedules and Annexes. The Pledgor shall, from time to time, amend or supplement in writing and deliver to the
Collateral Agent revisions of and supplements to the Annexes and schedules hereto to the extent necessary to disclose new or changed facts or circumstances arising after the date hereof, which, if existing or occurring on such date, would have been
required to be set forth or described in such Annex or schedule hereto; provided that (i) in connection with any amendment or supplement to Annex B, the Pledgor shall provide the Collateral Agent at least fifteen
(15) days’ advance written notice of any such amendment 

  
 15 

 
or supplement (or such shorter period as the Collateral Agent may approve in writing), shall comply with Section 4.2 and shall take any other action reasonably requested by
Collateral Agent in connection therewith to maintain the Lien of Collateral Agent on the Collateral after giving effect to such amendment or supplement, (ii) in connection with any amendment or supplement to Annex G, the Pledgor shall
provide the Collateral Agent at least fifteen (15) days’ advance written notice of any such amendment or supplement (or such shorter period as the Collateral Agent may approve), shall comply with Sections 3.9 and 4.11 and
shall take any other action reasonably requested by Collateral Agent in connection therewith to maintain the Lien of Collateral Agent on the Collateral after giving effect to such amendment or supplement, (iii) in connection with any amendment
or supplement to Annex C, the Pledgor shall comply with Section 4.2, (iv) in connection with any amendment or supplement to Annexes D, E or F, the Pledgor shall comply with Section 4.8(a), and
(v) no such amendment or supplement to any such Annex shall constitute a waiver of any Default or Event of Default in existence on or prior to the date of such amendment or supplement. Any reference to an Annex or schedule in this Agreement
shall refer to such Annex as amended or supplemented from time to time in accordance with this Section 4.12. Pledgor shall deliver an Officers’ Certificate (as defined in the Indenture) to the Collateral Agent certifying as to such
changed facts or circumstances. 
 ARTICLE V 

CERTAIN PROVISIONS RELATING TO EQUITY INTERESTS 

5.1 Ownership; After-Acquired Equity Interests. 

(a) Except as otherwise permitted by the Indenture, Pledgor will cause the Equity Interests pledged by it hereunder to constitute at all
times 100% of the capital stock or other Equity Interests in each subsidiary of Pledgor, such that the issuer thereof shall be a wholly owned subsidiary of Pledgor. Unless the Collateral Agent shall have given its prior written consent, Pledgor will
not cause or permit any such issuer to issue or sell any new capital stock, any warrants, options or rights to acquire the same, or other Equity Interests of any nature to any person other than Pledgor, or cause, permit or consent to the admission
of any other person as a stockholder, partner or member of any such issuer. 
 (b) If Pledgor shall, at any time and from time to time,
acquire any additional capital stock or other Equity Interests in any person of the types described in the definition of the term “Equity Interests”, the same shall be automatically deemed to be Equity Interests, and shall be deemed
to be pledged to the Collateral Agent pursuant to Section 2.1 and, subject to the Intercreditor Agreement, Pledgor will forthwith pledge and, subject to Section 8.16 hereof, deposit the same with the Collateral Agent and
deliver to the Collateral Agent any certificates or instruments therefor, together with the endorsement of Pledgor (in the case of any promissory notes or other Instruments), undated stock powers (in the case of Equity Interests evidenced by
certificates) or other necessary instruments of transfer or assignment, duly executed in blank, together with such other certificates and instruments as the Collateral Agent may, but is not required to, reasonably request (including Uniform
Commercial Code financing statements or appropriate amendments thereto), and will promptly thereafter deliver to the Collateral Agent a fully completed and duly executed amendment to this Agreement in the form of Exhibit A (each, a
“Pledge Amendment”) in respect thereof. Pledgor hereby authorizes the Collateral Agent to attach each such Pledge Amendment to this Agreement, and agrees that all such Collateral listed on any Pledge Amendment shall for all purposes
be deemed Collateral hereunder and shall be subject to the provisions hereof, provided that the failure of Pledgor to execute and deliver any Pledge Amendment with respect to any such additional Collateral as required hereinabove shall not
impair the security interest of the Collateral Agent in such Collateral or otherwise adversely affect the rights and remedies of the Collateral Agent hereunder with respect thereto. 

(c) Subject to the Intercreditor Agreement and Section 8.16 hereof, if any Equity Interests (whether now owned or hereafter
acquired) included in the Collateral are “uncertificated securities” within the meaning of the Uniform Commercial Code or are otherwise not evidenced by any certificate or instrument, each applicable Pledgor will promptly notify the
Collateral Agent in writing thereof and will promptly take and cause to be taken, and will (if the issuer of such uncertificated securities is a person other than a direct or indirect subsidiary of the Parent) use its best efforts to cause the
issuer to take, all actions required under Articles 8 and 9 of the Uniform Commercial Code and any other applicable law, to enable the Collateral Agent to acquire “control” (within the meaning of such term under Section 8-106 (or
its successor provision) of the Uniform Commercial Code) of such uncertificated securities and as may be otherwise necessary or deemed appropriate by the Collateral Agent to perfect the security interest of the Collateral Agent therein. 

  
 16 

 5.2 Voting Rights. So long as no Event of Default shall have occurred and be continuing,
Pledgor shall be entitled to exercise all voting and other consensual rights pertaining to its Equity Interests (subject to its obligations under Section 5.1) which have become Collateral, and for that purpose the Collateral Agent will
execute and deliver or cause to be executed and delivered to the Pledgor all such proxies and other instruments as the Pledgor may reasonably request in writing to enable the Pledgor to exercise such voting and other consensual rights;
provided, however, that the Pledgor will not cast any vote, give any consent, waiver or ratification, or take or fail to take any action, in any manner that would, or could reasonably be expected to, violate or be inconsistent with any
of the terms of this Agreement, the Intercreditor Agreement or the Indenture, or have the effect of impairing the position or interests of the Collateral Agent or any other Secured Party in such Collateral. 

5.3 Dividends and Other Distributions. Except as provided otherwise herein or in the Indenture, all interest, income, dividends,
distributions and other amounts payable in cash in respect of the Equity Interests which have become Collateral shall be paid to the Collateral Agent and retained by it in a non-interest bearing account as part of the Collateral (except to the
extent applied upon receipt to the repayment of the Secured Obligations). The Collateral Agent shall also be entitled at all times to receive directly, and to retain as part of the Collateral, (i) all interest, income, dividends, distributions
or other amounts paid or payable in cash or other property in respect of any Equity Interests which have become Collateral in connection with the dissolution, liquidation, recapitalization or reclassification of the capital of the applicable issuer
to the extent representing an extraordinary, liquidating or other distribution in return of capital, (ii) all additional Equity Interests or other securities or property (other than cash) paid or payable or distributed or distributable in
respect of any Equity Interests which have become Collateral in connection with any noncash dividend, distribution, return of capital, spin-off, stock split, split-up, reclassification, combination of shares or interests or similar rearrangement,
and (iii) without affecting any restrictions against such actions contained in the Indenture, all additional Equity Interests or other securities or property (including cash) paid or payable or distributed or distributable in respect of any
Equity Interests which have become Collateral in connection with any consolidation, merger, exchange of securities, liquidation or other reorganization. All interest, income, dividends, distributions or other amounts that are received by Pledgor in
violation of the provisions of this Section shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other property or funds of Pledgor and, subject to the Intercreditor Agreement and Section 8.16
hereof, shall be forthwith delivered to the Collateral Agent as Collateral in the same form as so received (with any necessary endorsements) or in the case of cash, by wire transfer pursuant to payment instructions provided by Collateral Agent to
Pledgor. Any such cash shall be retained in a non-interest bearing account. 
 ARTICLE VI 

REMEDIES 
 6.1
Remedies. If an Event of Default shall have occurred and be continuing, subject to the Intercreditor Agreement (which may limit or preclude the exercise of rights under this Article VI), the Collateral Agent, at the direction of the Trustee
acting upon the written direction of the appropriate percentage of Holders under the Indenture, as applicable, shall be entitled to exercise in respect of the Collateral all of its rights, powers and remedies provided for herein or otherwise
available to it under the Indenture, by law, in equity or otherwise, including all rights and remedies of a secured party under the Uniform Commercial Code, and shall be entitled in particular, but without limitation of the foregoing (other than as
provided in the Intercreditor Agreement), to exercise the following rights, which Pledgor agrees to be commercially reasonable: 
 (a) To
notify any or all account debtors or obligors under any Accounts or other Collateral of the security interest in favor of the Collateral Agent created hereby and to direct all such Persons to make payments of all amounts due thereon or thereunder
directly to the Collateral Agent or to an account designated by the Collateral Agent; and in such instance and from and after such notice, all amounts and Proceeds (including wire transfers, checks and other instruments) received by Pledgor in
respect of any Accounts or other Collateral shall be received in trust for the benefit of the Collateral Agent hereunder, shall be segregated from the other funds of Pledgor and, subject to the Intercreditor Agreement, shall be forthwith deposited
into such account or paid over or delivered to the Collateral Agent in the same form as so received (with any necessary endorsements or assignments), to be held as Collateral and applied to the Secured Obligations as provided herein; 

  
 17 

 (b) To receive, open and properly dispose of all mail addressed to Pledgor concerning Accounts
and other Collateral and to notify the appropriate postal authority to change the mailing or delivery address of such mail; to accelerate any indebtedness or other obligation constituting Collateral that may be accelerated in accordance with its
terms; to take or bring all actions and suits deemed necessary or appropriate to effect collections and to enforce payment of any Accounts or other Collateral; to settle, compromise or release in whole or in part any amounts owing on Accounts or
other Collateral; and to extend the time of payment of any and all Accounts or other amounts owing under any Collateral and to make allowances and adjustments with respect thereto, all in the same manner and to the same extent as Pledgor might have
done; 
 (c) Subject to applicable law and regulation, to transfer to or register in its name or the name of any of its agents or nominees
all or any part of the Collateral, without notice to Pledgor and with or without disclosing that such Collateral is subject to the security interest created hereunder; 

(d) Subject to applicable law and regulation, to require Pledgor to, and Pledgor hereby agrees that it will at its expense and upon request
of the Collateral Agent forthwith, assemble all or any part of the Collateral as directed by the Collateral Agent and to the extent permitted by applicable law make it available to the Collateral Agent at a place designated by the Collateral Agent
and Pledgor further agrees that the Collateral Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale; 

(e) To the extent permitted by applicable law, to enter and remain upon the premises of Pledgor and take possession of all or any part of the
Collateral, with or without judicial process; to use the materials, services, books and records of Pledgor for the purpose of liquidating or collecting the Collateral, whether by foreclosure, auction or otherwise; and to remove the same to the
premises of the Collateral Agent or any designated agent for such time as the Collateral Agent may desire or as is necessary or advisable, in order to effectively collect or liquidate the Collateral; 

(f) Subject to applicable law and regulation and the Intercreditor Agreement, to exercise, but only at the request of the Trustee acting in
accordance with the Indenture, to the extent permitted by applicable law, (i) all voting, consensual and other rights and powers pertaining to the Equity Interests (whether or not transferred into the name of the Collateral Agent), at any
meeting of shareholders, partners, members or otherwise, and (ii) any and all rights of conversion, exchange, subscription and any other rights, privileges or options pertaining to the Equity Interests as if it were the absolute owner thereof
(including, without limitation, the right to exchange any and all of the Equity Interests upon the merger, consolidation, reorganization, reclassification, combination of shares or interests, similar rearrangement or other similar fundamental change
in the structure of the applicable issuer, or upon the exercise by Pledgor or the Collateral Agent of any right, privilege or option pertaining to such Equity Interests), and in connection therewith, the right to deposit and deliver any and all of
the Equity Interests with any committee, depositary, transfer agent, registrar or other designated agency and give all consents, waivers and ratifications in respect of the Equity Interests, all without liability except to account for any property
actually received by it, but the Collateral Agent shall have no duty to exercise any such right, privilege or option or give any such consent, waiver or ratification and shall not be responsible for any failure to do so or delay in so doing; and for
the foregoing purposes Pledgor will promptly execute and deliver or cause to be executed and delivered to the Collateral Agent, all such proxies and other instruments to enable the Collateral Agent to exercise such rights and powers; AND IN
FURTHERANCE OF THE FOREGOING AND WITHOUT LIMITATION THEREOF, PLEDGOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS THE COLLATERAL AGENT AS THE TRUE AND LAWFUL PROXY AND ATTORNEY-IN-FACT OF PLEDGOR, WITH FULL POWER OF SUBSTITUTION IN THE PREMISES, UPON
THE OCCURRENCE AND DURING THE CONTINUANCE OF AN EVENT OF DEFAULT, TO EXERCISE ALL SUCH VOTING, CONSENSUAL AND OTHER RIGHTS AND POWERS TO WHICH ANY HOLDER OF ANY EQUITY INTERESTS WOULD BE ENTITLED BY VIRTUE OF HOLDING THE SAME, WHICH PROXY AND POWER
OF ATTORNEY, BEING COUPLED WITH AN INTEREST, IS IRREVOCABLE AND SHALL BE EFFECTIVE FOR SO LONG AS THIS AGREEMENT SHALL BE IN EFFECT; and 

  
 18 

 (g) Subject to applicable law and regulation, to sell, resell, assign and deliver all or any of
the Collateral, in one or more parcels, on any securities exchange on which any Equity Interests may be listed, at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, upon credit or for future delivery, at
such time or times and at such price or prices and upon such other terms as the Collateral Agent may deem satisfactory. If any of the Collateral is sold by the Collateral Agent upon credit or for future delivery, the Collateral Agent shall not be
liable for the failure of the purchaser to purchase or pay for the same and, in the event of any such failure, the Collateral Agent may, but is not required to, resell such Collateral. In no event shall Pledgor be credited with any part of the
Proceeds of sale of any Collateral until and to the extent cash payment in respect thereof has actually been received by the Collateral Agent. Each purchaser at any such sale shall hold the property sold absolutely, free from any claim or right of
whatsoever kind, including any equity or right of redemption of Pledgor, and Pledgor hereby expressly waives, to the fullest extent permitted under applicable law, all rights of redemption, stay or appraisal, and all rights to require the Collateral
Agent to marshal any assets in favor of Pledgor or any other party or against or in payment of any or all of the Secured Obligations, that it has or may have under any rule of law or statute now existing or hereafter adopted. No demand, presentment,
protest, advertisement or notice of any kind (except any notice required by law, as referred to below), all of which are hereby expressly waived by Pledgor, shall be required in connection with any sale or other disposition of any part of the
Collateral. If any notice of a proposed sale or other disposition of any part of the Collateral shall be required under applicable law, the Collateral Agent shall give the Pledgor at least ten (10) days’ prior notice of the time and place
of any public sale and of the time after which any private sale or other disposition is to be made, which notice Pledgor agrees is commercially reasonable. The Collateral Agent shall not be obligated to make any sale of Collateral if it shall
determine not to do so, regardless of the fact that notice of sale may have been given. 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 sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. Upon each public sale and, to the extent permitted by applicable law, upon each private sale, the
Collateral Agent may purchase all or any of the Collateral being sold, free from any equity, right of redemption or other claim or demand, and may make payment therefor by endorsement and application (without recourse) of the Secured Obligations in
lieu of cash as a credit on account of the purchase price for such Collateral. The Collateral Agent shall, to the extent required by applicable laws, comply with any applicable state or federal law requirements in connection with the sale or other
disposition of the Collateral and Pledgor agrees that such compliance is commercially reasonable. The Collateral Agent may sell or otherwise dispose of the Collateral without giving any warranties, specifically disclaiming any warranties of title or
the like and Pledgor agrees that such disclaimer is commercially reasonable. 
 6.2 Application of Proceeds. 

(a) Subject to the Intercreditor Agreement, all Proceeds collected by the Collateral Agent upon any sale, other disposition of or realization
upon any of the Collateral, together with all other moneys received by the Collateral Agent hereunder following the occurrence and during the continuance of an Event of Default shall be applied in accordance with the Indenture. 

(b) Pledgor shall remain liable to the extent of any deficiency between the amount of all Proceeds realized upon sale, other disposition or
collection of the Collateral, and monies held as Collateral pursuant to this Agreement and the aggregate amount of Secured Obligations. Upon any sale of any Collateral hereunder by the Collateral Agent (whether by virtue of the power of sale herein
granted, pursuant to judicial proceeding, or otherwise), the receipt by the Collateral Agent or the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold, and such purchaser or purchasers
shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof. 

6.3 Grant of License. To the extent permitted by applicable law and the Intercreditor Agreement and solely for the purpose of enabling
the Secured Parties to exercise rights and remedies under this Article VI, and at such time as the Secured Parties shall be lawfully entitled to exercise such rights and remedies, Pledgor hereby grants to the Collateral Agent, to the extent
it has the right to do so, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to Pledgor), subject, in the case of Trademarks, to sufficient rights to quality control and inspection in favor of
Pledgor to avoid the risk of invalidation of such 

  
 19 

 
Trademarks, to use, license or sublicense any Patent Collateral, Trademark Collateral or Copyright Collateral now owned or hereafter acquired by Pledgor, wherever the same may be located
throughout the world, for such term or terms, on such conditions and in such manner as the Collateral Agent shall determine, whether general, special or otherwise, and whether on an exclusive or nonexclusive basis, and including in such license
reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof. The use of such license or sublicense by the Collateral Agent shall
be exercised only upon the occurrence and during the continuation of an Event of Default; provided that any license, sublicense or other transaction entered into by the Collateral Agent in accordance herewith shall be binding upon each
applicable Pledgor notwithstanding any subsequent cure of an Event of Default. 
 6.4 Private Sales. 

(a) Pledgor recognizes that, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws as in
effect from time to time, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Equity Interests conducted without registration or qualification under the Securities Act and such state securities laws, to limit
purchasers to any one or more persons who will represent and agree, among other things, to acquire such Equity Interests for their own account, for investment and not with a view to the distribution or resale thereof. Pledgor acknowledges that any
such private sales may be made in such manner and under such circumstances as the Collateral Agent may deem necessary or advisable, including at prices and on terms less favorable than those obtainable through a public sale without such restrictions
(including, without limitation, a public offering made pursuant to a registration statement under the Securities Act), and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially
reasonable manner and agrees that the Collateral Agent shall have no obligation to conduct any public sales and no obligation to delay the sale of any Equity Interests for the period of time necessary to permit its registration for public sale under
the Securities Act and applicable state securities laws, and shall not have any responsibility or liability as a result of its election so not to conduct any such public sales or delay the sale of any Equity Interests, notwithstanding the
possibility that a substantially higher price might be realized if the sale were deferred until after such registration. Pledgor hereby waives any claims against the Collateral Agent or any other Secured Party arising by reason of the fact that the
price at which any Equity Interests may have been sold at any private sale was less than the price that might have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, even if the Collateral Agent accepts
the first offer received and does not offer such Equity Interests to more than one offeree. 
 (b) Pledgor agrees that a breach of any of
the covenants contained in this Section will cause irreparable injury to the Collateral Agent and the other Secured Parties, that the Collateral Agent and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this Section shall be specifically enforceable against the Pledgor. 
 6.5
Waivers. Pledgor, to the greatest extent not prohibited by applicable law, hereby (i) agrees that it will not invoke, claim or assert the benefit of any rule of law or statute now or hereafter in effect (including, without limitation,
any right to prior notice or judicial hearing in connection with the Collateral Agent’s possession, custody or disposition of any Collateral or any appraisal, valuation, stay, extension, moratorium or redemption law), or take or omit to take
any other action, that would or could reasonably be expected to have the effect of delaying, impeding or preventing the exercise of any rights and remedies in respect of the Collateral, the absolute sale of any of the Collateral or the possession
thereof by any purchaser at any sale thereof, and waives the benefit of all such laws and further agrees that it will not hinder, delay or impede the execution of any power granted hereunder to the Collateral Agent, but that it will permit the
execution of every such power as though no such laws were in effect, (ii) waives all rights that it has or may have under any rule of law or statute now existing or hereafter adopted to require the Collateral Agent to marshal any Collateral or
other assets in favor of Pledgor or any other party or against or in payment of any or all of the Secured Obligations, and (iii) waives all rights that it has or may have under any rule of law or statute now existing or hereafter adopted to
demand, presentment, protest, advertisement or notice of any kind (except notices expressly provided for herein or in the other Financing Documents) or to require the Collateral Agent to pursue any third party for any of the Secured Obligations.

 ARTICLE VII 

THE COLLATERAL AGENT 
 7.1
The Collateral Agent; Standard of Care. 
 (a) The Collateral Agent will hold all items of the Collateral at any time received under
this Agreement in accordance with the provisions hereof and the Indenture. The obligations of the Collateral Agent as holder of the Collateral and interests therein and with respect to the disposition thereof, and otherwise under this Agreement and
the Indenture are only those expressly set forth in this Agreement and the Indenture. The Collateral Agent shall act at the direction of the Trustee (acting on written direction of the appropriate percentage of Holders under the Indenture) who shall
give directions to the Collateral Agent pursuant to the Indenture. The powers conferred on the Collateral Agent hereunder are solely to protect its interest, on behalf of the Secured Parties, in the Collateral, and shall not impose any duty upon it
to exercise any such powers. The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral, shall not impose any duty upon the Collateral Agent to exercise any such powers and shall not make the
Collateral Agent liable to any Person. Except for treatment of the Collateral in its possession in the same manner as that which the Collateral Agent, in its individual capacity, accords its own property of a similar nature for its own account, and
the accounting for moneys actually received by it hereunder in the exercise of reasonable care, the Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any
other rights pertaining to the Collateral. Neither the Collateral Agent nor any other Secured Party shall be liable to Pledgor (i) for any loss or damage sustained by Pledgor, or (ii) for any loss, damage, depreciation or other diminution
in the value of any of the Collateral that may occur as a result of or in connection with or that is in any way related to any exercise by the Collateral Agent or any other Secured Party of any right or remedy under this Agreement, any failure to
demand, collect or realize upon any of the Collateral or any delay in doing so, or any other act or failure to act on the part of the Collateral Agent or any other Secured Party, except to the extent that the same is caused by its own gross
negligence or willful misconduct. 
 (b) The Collateral Agent shall not be responsible for and makes no representation as to the existence,
genuineness, value or protection of any Collateral, for the legality, effectiveness or sufficiency of any Security Document, or for the creation, perfection, priority, sufficiency or protection of any Liens securing the Secured Obligations. For the
avoidance of doubt, nothing herein shall require the Collateral Agent to file financing statements, continuation statements or termination statements, or be responsible for maintaining the security interests purported to be created as described
herein (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder or under any other Security Document) and such responsibility shall be solely that of the Pledgor. In connection
with its execution and acting under this Agreement, the Collateral Agent is entitled to all rights, privileges, protections, immunities, benefits and indemnities provided to it under the other Security Documents, all of which are incorporated by
reference herein mutatis mutandis. Notwithstanding anything to the contrary herein, express or implied, the Collateral Agent shall have no duty to take any discretionary action or exercise any discretionary powers (including making any
determination or deeming any matter appropriate, necessary or satisfactory) unless it first receives written direction from the Trustee acting on behalf of the appropriate percentage of Holders under the Indenture. Furthermore, if the Collateral
Agent shall not have received appropriate instruction within 10 days of a request therefor from the Trustee (or such shorter period as reasonably may be specified in such notice or as may be necessary under the circumstances) it may, but shall be
under no duty to, take or refrain from taking such action as it shall deem to be in the best interests of the itself and the Trustee and the Collateral Agent shall have no liability to any Person for such action or inaction. 

(c) Notwithstanding anything to the contrary herein, whenever reference is made in this Agreement to any action by, consent, designation,
specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Collateral Agent, to any amendment, waiver or other
modification of this Agreement to be executed (or not to be executed) by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be
made (or not to be made) by the Collateral Agent, it is understood that in all cases the Collateral Agent shall be acting, giving, withholding, suffering, omitting, making or otherwise undertaking and exercising the same (or shall not be undertaking
and exercising the same) as 

  
 21 

 
directed in accordance with the written direction of the Trustee acting upon the written direction of the appropriate percentage of Holders under the Indenture, as applicable. This provision is
intended solely for the benefit of the Collateral Agent and its successors and permitted assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim under or in relation to any Security
Document, or confer any rights or benefits on any party hereto. 
 7.2 Further Assurances; Attorney-in-Fact. 

(a) Pledgor hereby authorizes the Collateral Agent to sign (to the extent the Pledgor’s signature is required thereon) financing
statements and amendments thereto relating to all or any part of the Collateral without the signature of Pledgor (including, without limitation, making any notice filings with state tax or revenue authorities required to be made by account creditors
in order to enforce any Accounts in such state); provided that, promptly following the filing thereof, the Pledgor shall provide the Collateral Agent with a copy of any initial financing statement filed by it or any amendment to any initial
financing statement which changes the collateral description set forth therein. The Pledgor further agrees to execute and deliver to the Collateral Agent such additional conveyances, assignments, agreements and instruments as the Collateral Agent
may reasonably require under applicable law to perfect, establish, confirm and maintain the security interest and Lien provided for herein, to carry out the purposes of this Agreement or to further assure and confirm unto the Collateral Agent its
rights, powers and remedies hereunder. 
 (b) Pledgor hereby irrevocably appoints the Collateral Agent its lawful attorney-in-fact, with
full authority in the place and stead of Pledgor and in the name of Pledgor, the Collateral Agent or otherwise, and with full power of substitution in the premises (which power of attorney, being coupled with an interest, is irrevocable for so long
as this Agreement shall be in effect), from time to time, after the occurrence and during the continuance of an Event of Default (except for the actions described in clauses (ii), (iv) and (vii) below which may be taken by the
Collateral Agent without regard to whether an Event of Default has occurred) to take any action and to execute any instruments that are necessary or advisable to accomplish the purpose of this Agreement, including, without limitation: 

(i) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to
become due under or in respect of any of the Collateral; 
 (ii) to receive, endorse and collect any checks, drafts,
instruments, chattel paper and other orders for the payment of money made payable to Pledgor representing any interest, income, dividend, distribution or other amount payable in respect of any of the Collateral and to give full discharge for the
same; 
 (iii) to obtain, maintain and adjust any property or casualty insurance required to be maintained by Pledgor under
Section 4.7 and direct the payment of proceeds thereof to the Collateral Agent; 
 (iv) to pay or discharge
taxes, Liens or other encumbrances levied or placed on or threatened against the Collateral, the legality or validity thereof and the amounts necessary to discharge the same to be determined by the Collateral Agent, any such payments made by the
Collateral Agent to become Secured Obligations of the Pledgor to the Collateral Agent, due and payable immediately and without demand (provided that the Collateral Agent shall not pay any tax obligation being contested by the Pledgor as
indicated on Schedule II hereto); 
 (v) to file any claims or take any action or institute any proceedings that the
Collateral Agent may deem necessary or advisable for the collection of any of the Collateral or otherwise to enforce the rights of the Collateral Agent with respect to any of the Collateral; 

(vi) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with any and all of the
Collateral as fully and completely as though the Collateral 

  
 22 

 
Agent were the absolute owner of the Collateral for all purposes, and to do from time to time, at the Collateral Agent’s option and the Pledgor’s expense, all other acts and things
necessary to protect, preserve or realize upon the Collateral and to more completely carry out the purposes of this Agreement; and 

(vii) to sign the name of Pledgor on (to the extent the Pledgor’s signature is required thereon) and to file any
financing statement, continuation statement, notice or other similar document that, in the Collateral Agent’s Permitted Discretion, should be made or filed in order to perfect or continue to perfect the security interest granted under this
Agreement; 
 (c) If Pledgor fails to perform any covenant or agreement contained in this Agreement after written request to do so by the
Collateral Agent (provided that no such request shall be necessary at any time after the occurrence and during the continuance of an Event of Default), the Collateral Agent may itself perform, or cause the performance of, such covenant or
agreement and may take any other action that it deems necessary and appropriate for the maintenance and preservation of the Collateral or its security interest therein, and the reasonable expenses so incurred in connection therewith shall be payable
by the Pledgor under Section 8.1. 
 ARTICLE VIII 

MISCELLANEOUS 
 8.1
Indemnity and Expenses. The Pledgor agrees: 
 (a) to indemnify and hold harmless the Collateral Agent, the Trustee, each other
Secured Party and each of their respective directors, officers, employees, agents and affiliates from and against any and all claims, damages, demands, losses, obligations, judgments and liabilities (including, without limitation, reasonable
attorneys’ fees, out of pocket costs and expenses) in any way arising out of or in connection with this Agreement, except to the extent the same shall arise as a result of the gross negligence or willful misconduct of the party seeking to be
indemnified; and 
 (b) to pay and reimburse the Collateral Agent and the Trustee upon demand for all reasonable costs and expenses
(including, without limitation, reasonable attorneys’ fees, out of pocket costs and expenses) that the Collateral Agent may incur in connection with (i) the custody, use or preservation of, or the sale of, collection from or other
realization upon, any of the Collateral, including the reasonable expenses of retaking, holding, preparing for sale or lease, selling or otherwise disposing of or realizing on the Collateral, (ii) the exercise or enforcement of any rights or
remedies granted hereunder (including, without limitation, under Article VI), under the Indenture or Notes or otherwise available to it (whether at law, in equity or otherwise), or (iii) the failure by Pledgor to perform or observe
any of the provisions hereof. The provisions of this Section shall survive the execution and delivery of this Agreement, the repayment of any of the Secured Obligations and the discharge of the Indenture. 

8.2 No Waiver. The rights and remedies of the Secured Parties expressly set forth in this Agreement, the Indenture and the Notes are
cumulative and in addition, to, and not exclusive of, all other rights and remedies available at law, in equity or otherwise. No failure or delay on the part of any Secured Party in exercising any right, power or privilege shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or privilege preclude any other or further exercise thereof or the exercise of any other right, power or privilege or be construed to be a waiver of any Default or Event of
Default. No course of dealing between the Pledgor and the Secured Parties or their agents or employees shall be effective to amend, modify or discharge any provision of this Agreement or the Indenture or Notes or to constitute a waiver of any
Default or Event of Default. No notice to or demand upon Pledgor in any case shall entitle Pledgor to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of any Secured Party to exercise any
right or remedy or take any other or further action in any circumstances without notice or demand. 
 8.3 Pledgor’s Obligations
Absolute. Until such time as this Agreement terminates pursuant to Section 8.6, Pledgor agrees that its obligations hereunder, and the security interest granted to and all rights, remedies and

  
 23 

 
powers of, the Collateral Agent hereunder, are irrevocable, absolute and unconditional and shall not be discharged, limited or otherwise affected (unless agreed to by the parties hereto) by
reason of any of the following, whether or not Pledgor has knowledge thereof: 
 (i) any change in the time, manner or place
of payment of, or in any other term of, any Secured Obligations, or any amendment, modification or supplement to, restatement of, or consent to any rescission or waiver of or departure from, any provisions of the Indenture, the Guarantee, the Notes,
any other Security Document or any agreement or instrument delivered pursuant to any of the foregoing;

or other action or inaction in respect of any Collateral or other direct or indirect security for any Secured Obligations, or any discharge, modification, settlement, compromise or other action or inaction in respect of any Secured Obligations; 

(v) any agreement not to pursue or enforce or any failure to pursue or enforce (whether voluntarily or involuntarily as a
result of operation of law, court order or otherwise) any right or remedy in respect of any Secured Obligations or any Collateral or other security therefor, or any failure to create, protect, perfect, secure, insure, continue or maintain any Liens
in any such Collateral or other security; 
 (vi) the exercise of any right or remedy available under the Indenture, the
Notes or other Security Document, at law, in equity or otherwise in respect of any Collateral or other security for any Secured Obligations, in any order and by any manner thereby permitted, including, without limitation, foreclosure on any such

(viii) any manner of application of any payments by or amounts received or collected from any person, by whomsoever paid and
howsoever realized, whether in reduction of any Secured Obligations or any other obligations of the Issuer, Pledgor or any other person directly or indirectly liable for any Secured Obligations, regardless of what Secured Obligations may remain
unpaid after any such application; or 
 (ix) any other circumstance that might otherwise constitute a legal or equitable
discharge of, or a defense, set-off or counterclaim available to, the Issuer, Pledgor or a surety or guarantor generally, other than a satisfaction and discharge of the Indenture pursuant to Article 12 of the Indenture or a Legal Defeasance or
Covenant Defeasance or as otherwise provided in Section 10.04 of the Indenture. 
 8.4 Enforcement. By its acceptance of the
benefits of this Agreement, each Secured Party agrees that this Agreement may be enforced only by the Collateral Agent, acting upon the instructions or with the consent of the the Trustee who shall act in accordance with the Indenture, and that no
Secured Party shall have any right individually to enforce or seek to enforce this Agreement or to realize upon any Collateral or other security given to secure the payment and performance of the Secured Obligations. 

  
 24 

 8.5 Amendments, Waivers, etc. No amendment, modification, waiver, discharge or termination
of, or consent to any departure by Pledgor from, any provision of this Agreement, shall be effective unless in a writing executed and delivered in accordance with Article 9 of the Indenture, and then the same shall be effective only in the specific

Inventory or Equipment by foreclosure or otherwise pursuant to existing general licenses from the NRC issued to and generally available for use by any person) that involve taking possession or controlling the use of nuclear materials or facilities
for which a Permit is required, are subject to regulatory restrictions that may require the Collateral Agent to obtain the prior written consent or approval of the NRC, and all provisions of this Security Agreement shall be limited to conform with
such restrictions. For purposes hereof, “Permits” means permits, licenses, certificates, approvals and other authorizations issued by the NRC, or by a state agency exercising NRC’s authority under an agreement with the NRC.

reasonable efforts to continue with respect to each of the following until such efforts are successful as to one of the following or such efforts are unsuccessful as to all of the following): (i) obtain the consent of the applicable holders of
Designated Senior Claims or their agent(s) or other representative(s) and the applicable deposit bank, securities intermediary, issuer or custodian, as applicable, to the Collateral Agent retaining its own separate control agreement reflecting the
priorities established by the Intercreditor Agreement, (ii) obtain the consent of the applicable holders of Designated Senior Claims or their agent(s) or other representative(s) and the applicable deposit bank, securities intermediary, issuer
or custodian, as applicable, to the Collateral Agent being a party to the control agreement in favor of the holders of Designated Senior Claims or their agent(s) and pursuant to such control agreement having the applicable deposit bank, securities
intermediary, issuer or custodian, as applicable, agree to follow instructions or entitlement orders, as applicable, of the Collateral Agent without further consent of the Company upon a discharge of the Designated Senior Claims, or (iii) in
the event that the provisions of Sections 8-106 and 9-104 of the Uniform Commercial Code are amended in a manner consistent with that set forth in Assembly Bill 9933, cause any control agreement for the benefit of any holders of Designated Senior
Claims to be subject to the Uniform Commercial Code. 
 8.17 No Recourse to the United States. The obligations of the Pledgor under
this Agreement, the Indenture and the Notes are the obligations of the Pledgor and are not obligations of, or guaranteed as to principal or interest by, the United States.

Subordination. 
 2.1 Subordination of Subordinated Debt to Senior Debt. The Issuer agrees, and the Trustee agrees
on behalf of each Holder, that the Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 2, to the prior payment in full of all Issuer Senior Debt (whether outstanding on
the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of and enforceable by holders of Issuer Senior Debt. The Indebtedness evidenced by the Notes shall in all respects rank
pari passu in right of payment with all existing and future unsubordinated Indebtedness of the Issuer (other than Issuer Senior Debt) and will be senior in right of payment to all existing and future subordinated Indebtedness of
the Issuer; and only Indebtedness that is Issuer Senior Debt shall rank senior to the Indebtedness evidenced by the Notes in accordance with the provisions set forth herein. All provisions of this Article 2 shall be subject to Section 2.11
hereof. 

  
 3 

 2.2 Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the
assets of the Issuer to creditors upon a total or partial liquidation or a total or partial dissolution of the Issuer or in a bankruptcy, reorganization, insolvency, receivership of or similar proceeding relating to the Issuer or its property, in an
assignment for the benefit of creditors or in any marshaling of the Issuer’s assets and liabilities: 
 (a)
holders of Issuer Senior Debt shall be entitled to receive payment in full in cash of such Issuer Senior Debt (including interest accruing after, or which would accrue but for, the commencement of any such proceeding at the rate specified in the
applicable Issuer Senior Debt, whether or not a claim for such interest would be allowed) before the Holders of Notes shall be entitled to receive any payment with respect to the Notes; and 

(b) until all Obligations with respect to the Issuer Senior Debt (as provided in clause (a) above) are paid in full in
cash, any payment or distribution to which Holders of Notes would be entitled but for this Article 2 shall be made to holders of Issuer Senior Debt as their interests may appear. 

2.3 Default on Issuer Senior Debt. 

(a) The Issuer may not make any payment or distribution to the Trustee or any Holder in respect of Obligations with respect to
the Notes and may not acquire from the Trustee or any Holder any Notes for cash or property until all principal and other Obligations with respect to the Issuer Senior Debt have been paid in full if: 

(i) a payment default on Issuer Senior Debt occurs and is continuing; or 

(ii) any other default occurs and is continuing on any Issuer Senior Debt that permits the holders of such Issuer Senior Debt
to accelerate its maturity, or otherwise demand its payment, and the Trustee receives a notice of such default (a “Notes Payment Blockage Notice”) from the Issuer or the holders of such Issuer Senior Debt. 

(b) The Issuer may and will resume payments or any distributions in respect of the Notes and may acquire them upon the earlier
of: 
 (i) in the case of a payment default with respect to any Issuer Senior Debt, the date upon which such default is cured
or waived, and 
 (ii) in the case of a nonpayment default with respect to any Issuer Senior Debt, upon the earlier of the
date on which such nonpayment default is cured or waived and 179 days after the date on which the applicable Notes Payment Blockage Notice is received, unless in the case of this clause (ii), the maturity of any Issuer Senior Debt has been
accelerated or demand for payment of such Issuer Senior Debt made, and such acceleration or demand for payment has not been waived or cancelled, 

if this Article 2 otherwise permits such payment, distribution or acquisition at the time of such payment, distribution or acquisition. 

2.4 Demand for Payment. If payment of the Notes is accelerated because of an Event of Default, the Issuer or the Trustee will
promptly notify holders of the Issuer Senior Debt, 

  
 4 

 
of the acceleration; provided that any failure to give such notice shall have no effect whatsoever on the provisions of this Article 2. If any Issuer Senior Debt is outstanding, the Issuer may
not make a payment of the Notes until ten (10) Business Days after holders of such Issuer Senior Debt receive notice of such acceleration and, thereafter, may make a payment of any Obligations with respect to the Notes only if this Agreement,
the Indenture and federal law otherwise permits payment at that time. 
 2.5 When Distribution Must be Paid Over. In the event
that the Trustee or any Holder of the Notes receives any payment of, or any distributions with respect to, any Obligations with respect to the Notes at a time when the payment is prohibited by Section 2.3 hereof and the Trustee or the Holder,
as applicable, has actual knowledge that the payment is prohibited by Section 2.3 hereof, such payment will be held by the Trustee or such Holder, in trust for the benefit of, and will be paid forthwith over and delivered upon written request
to, holders of Issuer Senior Debt as their interests may appear under the agreement, indenture or other document (if any) pursuant to which any Issuer Senior Debt may have been issued or incurred, for application to the payment of all Obligations
with respect to Issuer Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Issuer Senior Debt.

 2.6 Subrogation. After all Issuer Senior Debt is Discharged and until the Notes are paid in full, Holders of Notes will
be subrogated to the rights of the holders of Issuer Senior Debt to receive distributions applicable to such Issuer Senior Debt to the extent that distributions otherwise payable to the Holders of Notes have been applied to the payment of such
Issuer Senior Debt. A distribution made under this Article 2 to the holders of Issuer Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Issuer and Holders, a payment by the Issuer on the Notes. 

2.7 Relative Rights. This Article 2 defines the relative rights of Holders of Notes and holders of Issuer Senior Debt. Nothing
in this Agreement will: 
 (a) impair, as between the Issuer and Holders of Notes, the obligation of the Issuer, which
is absolute and unconditional, to pay principal of, premium on, if any, and interest, if any, on, the Notes in accordance with their terms; 

(b) affect the relative rights of Holders of Notes and creditors of the Issuer other than their rights in relation to holders
of Issuer Senior Debt; or 
 (c) prevent the Trustee or any Holder of Notes from exercising its available remedies upon a
Default or Event of Default, subject to the rights of holders of Issuer Senior Debt to receive distributions and payments otherwise payable to Holders of Notes and such other rights of holders of Issuer Senior Debt as set forth herein. 

2.8 Subordination May Not Be Impaired by the Issuer. No right of the holders of Issuer Senior Debt to enforce the subordination
of the Indebtedness evidenced by the Notes may be impaired by any act or failure to act by the Issuer or any Holder or by the failure of the Issuer or any Holder to comply with the Indenture or this Agreement. 

2.9 Rights of Trustee and Paying Agent. 

(a) Notwithstanding the provisions of this Article 2 or any provision of the Indenture, the Trustee will not be charged with
knowledge of the existence of any facts 

  
 5 

 
that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes, unless the Trustee has received at
its Corporate Trust Office at least three (3) Business Days prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article 2. Only the Issuer or
holders of Issuer Senior Debt may give the notice. Nothing in this Article 2 will impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 of the Indenture. 

(b) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a
participant in, DTC or other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant,
member, beneficial owner or other Person (other than DTC) of any notice (including any notice of redemption or purchase) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to such Notes. 

All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made
only to the registered Holders (which shall be DTC or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through DTC subject to the applicable rules and procedures of DTC. The
Trustee may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among DTC participants, members or beneficial owners in any Global Note) other than to require delivery of such
certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof. 
 2.10 Article 2 Not to Prevent Events of Default or Limit Right to Demand Payment. The failure of the
Issuer to make a payment on the Notes by reason of any provision in this Article 2 shall not be construed as preventing the occurrence of a Default by the Issuer. Nothing in this Article 2 shall have any effect on the right of the Holders or the
Trustee to make a demand for payment on the Notes pursuant to Article 2 of the Indenture. 
 2.11 Trust Moneys Not
Subordinated. Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of Government Securities held in trust by the Trustee for the payment of principal of and interest on the Notes pursuant to Article
8 or Article 12 of the Indenture shall not be subordinated to the prior payment of any Issuer Senior Debt or subject to the restrictions set forth in this Article 2, and none of the Holders shall be obligated to pay over any such amount to the
Issuer or holders of Issuer Senior Debt or any other creditor of the Issuer, provided that, the subordination provisions of this Article 2 were not violated at the time the applicable amounts were deposited in trust pursuant to Article 8 or Article
12 of the Indenture, as the case may be. 

  
 6 

 2.12 Trustee Entitled to Rely. Upon any payment or distribution of assets of the
Issuer referred to in this Article 2, the Trustee and the Holders of Notes will be entitled to rely upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 2.12 hereof are
pending or upon any certificate of such representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of Notes for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of Issuer Senior Debt and other Indebtedness of the Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article
2. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of the holders of Issuer Senior Debt to participate in any payment or distribution pursuant to this Article 2, the Trustee shall be
entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Issuer Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or
distribution and other facts pertinent to the rights of such Person under this Article 2 and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such Person pending judicial determination as to the right of such
Person to receive such payment. The provisions of Section 7.01 and Section 7.02 of the Indenture shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 2. 

2.13 Trustee to Effectuate Subordination. This Agreement is intended to effectuate the subordination provided in Article 2 of
the Indenture as contemplated by Section 2.27 of the Indenture.  
 2.14 Trustee Not Fiduciary for Holders of Issuer
Senior Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Issuer Senior Debt and shall not be liable to any such holder if it shall mistakenly pay over or distribute to or on behalf of Holders or any other
Person, money or assets to which holders of Issuer Senior Debt shall be entitled by virtue of this Article 2 or otherwise, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. 

2.15 Reliance by Holders of Senior Debt on Subordinated Provisions. Each Holder pursuant to the Indenture and by accepting a
Note, has acknowledged and agreed that provisions comparable to those in this Article 2 hereof are, and are intended to be, an inducement and a consideration to holders of Issuer Senior Debt, whether such Issuer Senior Debt was created or acquired
before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Issuer Senior Debt and holders of such Issuer Senior Debt shall be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Issuer Senior Debt.  
 Without in any way limiting the generality
of the foregoing paragraph, holders of Issuer Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders, without incurring liability to the Trustee or the Holders and without impairing or
releasing the subordination provided in this Article 2 or the obligations hereunder of the Holders to holders of Issuer Senior Debt, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of
payment of, or renew or alter, any Issuer Senior Debt, or otherwise amend or supplement in any manner any Issuer Senior Debt, or any instrument evidencing the same or any agreement under which any Issuer Senior Debt is

  
 7 

 
outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing any Issuer Senior Debt; (iii) release any Person liable in any
manner for the payment or collection of any Issuer Senior Debt; and (iv) exercise or refrain from exercising any rights against the Issuer and any other Person. 

3. Miscellaneous 
 3.1
Integration/Conflicts. This Agreement and the Indenture represent the entire agreement with respect to the subject matter hereof and thereof, and supersede any and all previous agreements and understandings, oral or written, relating to
the subject matter hereof and thereof. There are no promises, undertakings, representations or warranties by the Trustee or the Holders relative to the subject matter hereof and thereof not expressly set forth or referred to herein or therein. In
the event of any conflict between the provisions of this Agreement and the provisions of the Indenture, the provisions of this Agreement shall govern and control. 

3.2 Effectiveness; Continuing Nature of this Agreement; Severability. This Agreement shall become effective when executed and
delivered by the parties hereto. This is a continuing agreement of payment subordination and the Issuer Senior Debt Claimholders may continue, at any time and without notice to the Trustee or any Holder, to extend credit and other financial
accommodations and lend monies to or for the benefit of the Issuer constituting Issuer Senior Debt in reliance hereon. The terms of this Agreement shall survive, and shall continue in full force and effect, in any filing or proceeding under the
Bankruptcy Code. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating 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 hereto shall endeavor in good-faith negotiations to replace any
invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to those of the invalid, illegal or unenforceable provisions. All references to the Issuer shall include the Issuer as debtor
and debtor-in-possession and any receiver, trustee or similar person acting for the Issuer (as the case may be) in any proceeding under the Bankruptcy Code. This
Agreement shall terminate and be of no further force and effect: 
 (a) with respect to any Issuer Senior Debt
Representative and the Issuer Senior Debt Claimholders represented by it and their Issuer Senior Debt Obligations, on the date on which the Issuer Senior Debt Obligations of such Issuer Senior Debt Claimholders are Discharged subject to the rights
of such Issuer Senior Debt Claimholders under Section 3.20 and Section 3.21; and 
 (b) with respect
to the Trustee and the Holders on the date that all Issuer Senior Debt has been Discharged subject to the rights of such Issuer Senior Debt Claimholders under Section 3.20 and Section 3.21; 

provided, however, that in each case, such termination shall not relieve any such party of its obligations incurred hereunder prior to the date
of such termination. 
 3.3 Amendments; Waivers  

(a) No amendment, modification or waiver of any of the provisions of this Agreement shall be deemed to be made unless the same
shall be in writing signed on behalf of each party hereto or its authorized agent and each waiver, if any, shall be a 

  
 8 

 
waiver only with respect to the specific instance involved and shall in no way impair the rights of the parties making such waiver or the obligations of the other parties to such party in any
other respect or at any other time. Notwithstanding the foregoing, the Issuer shall not have any right to consent to or approve any amendment, modification or waiver of any provision of this Agreement except to the extent its rights are directly and
adversely affected. 
 (b) Notwithstanding the foregoing, without the consent of the Issuer or any party hereto any Person
holding Issuer Senior Debt or their agent, trustee or representative may become a party hereto by execution and delivery of a Joinder Agreement in accordance with Section 3.7 of this Agreement and upon such execution and delivery, such
Additional Issuer Senior Representative and the Additional Issuer Senior Debt Claimholders represented thereby shall be subject to the terms hereof. 

3.4 Information Concerning Financial Condition of the Issuer and its Subsidiaries. The Issuer Senior Debt Representatives and
the Issuer Senior Debt Claimholders, on the one hand, and the Holders, on the other hand, shall each be responsible for keeping themselves informed of (a) the financial condition of the Issuer, its Subsidiaries and any endorsers and guarantors
of the Issuer Senior Debt Obligations or the Notes and (b) all other circumstances bearing upon the risk of nonpayment of the Issuer Senior Debt Obligations or the Notes. The Issuer Senior Debt Representatives and the other Issuer Senior Debt
Claimholders, on the one hand, and the Holders, on the other hand, shall have no duty to advise of information known to it or them regarding such condition or any such circumstances or otherwise. In the event any Claimholder, in its sole discretion,
undertakes at any time or from time to time to provide any such information to any other Claimholder, it shall be under no obligation: 

(a) to make, and such Claimholder shall not make, any express or implied representation or warranty, including with respect to
the accuracy, completeness, truthfulness or validity of any such information so provided; 
 (b) to provide any additional
information or to provide any such information on any subsequent occasion; 
 (c) to undertake any investigation; or 

(d) to disclose any information, which pursuant to accepted or reasonable commercial finance practices, such party wishes to
maintain confidential or is otherwise required to maintain confidential. 
 3.5 Subrogation. With respect to the value of any
payments or distributions in cash, property or other assets that any of the Trustee or the Holders pays over to any of the Issuer Senior Debt Representatives or the other Issuer Senior Debt Claimholders under the terms of this Agreement, the Trustee
or such Holders shall be subrogated to the rights of such Issuer Senior Debt Representatives or the other Issuer Senior Debt Claimholders; provided that the Trustee, on behalf of itself and each Holder, hereby agrees not to assert or enforce any
such rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of all Issuer Senior Debt has occurred. The Company acknowledges and agrees that the value of any payments or distributions in cash, property or other
assets received by the Trustee or any Holder that are paid over to any Issuer Senior Debt Representatives or the other Issuer Senior Debt Claimholders pursuant to this Agreement shall not reduce any of the obligations under the Indenture.

  
 9 

 3.6 Application of Payments. All payments received by any Issuer Senior Debt
Representative or other Issuer Senior Debt Claimholder may be applied, reversed and reapplied, in whole or in part, to such part of the Issuer Senior Debt Obligations provided for in the applicable Issuer Senior Debt or the documents evidencing or
governing such Issuer Senior Debt (subject to any agreement among the Issuer Senior Debt Representatives). The Trustee, on behalf of itself and each Holder, agrees to any extension or postponement of the time of payment of the Issuer Senior Debt
Obligations or any part thereof and to any other indulgence with respect thereto, to any substitution, exchange or release of any payment which may at any time secure any part of the Issuer Senior Debt Obligations and to the addition or release of
any other Person primarily or secondarily liable therefor. 
 3.7 Additional Issuer Senior Debt Claims. Any Person
holding Issuer Senior Debt or their agent, trustee or representative may, but is not obligated to, become a party hereto by execution and delivery of a joinder agreement in substantially the form of Exhibit A hereto.  

3.8 Agency Capacities. The Company is acting in the capacity of Initial Issuer Senior Debt Representative solely for the Initial
Issuer Senior Debt Claimholders. Each other Issuer Senior Debt Representative is acting in the capacity of Issuer Senior Debt Representative solely for the Issuer Senior Debt Claimholders for which it has been appointed agent, trustee or other
representative. The Trustee is acting as Trustee solely for the Holders. 
 3.9 Submission to Jurisdiction; Certain
Waivers. Each of the Issuer and each Issuer Senior Debt Representative and the Trustee, on behalf of itself and each other applicable Claimholder represented by it, hereby irrevocably and unconditionally: 

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement (whether arising in
contract, tort or otherwise) to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the exclusive general jurisdiction of the courts of the State of New York sitting in the Borough of Manhattan, the courts
of the United States for the Southern District of New York sitting in the Borough of Manhattan, and appellate courts from any thereof; 

(b) agrees that all claims in respect of any such action or proceeding shall be heard and determined in such New York state

 3.21 Avoidance Issues. If any Issuer Senior Debt Claimholder is required as a result of any filing or proceeding
under the Bankruptcy Code or otherwise to turn over or otherwise pay to the estate of the Issuer any amount paid in respect of Issuer Senior Debt Obligations (a “Recovery”), then such Issuer Senior Debt Claimholder shall be entitled
to a reinstatement of its Issuer Senior Debt Obligations with respect to all such recovered amounts on the date of such Recovery, and from and after the date of such reinstatement the Discharge of Issuer Senior Debt Obligations shall be deemed not
to have occurred for all purposes hereunder. 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
