 2. Transfer and Acceptance. 

2.1 Specified Collateral. 

(a) At the Effective Time, at the direction of the Collateral Agent (which shall be deemed to have been given hereunder
automatically and immediately at the Effective Time), the Borrower hereby assigns, transfers and delivers to the Collateral Agent (for further distribution to the Applicable Transferees of their Ratable Shares thereof in accordance with the terms of
the Loan Documents) (or, if directed to do so in writing by the Collateral Agent prior to the Effective Time (such direction, the “Applicable Transferee Distribution Direction”), directly to the respective Applicable Transferees),
and the Collateral Agent (or relevant Applicable Transferee, if the Applicable Transferee Distribution Direction has been provided) shall, in accordance with the Credit Agreement and the other Loan Documents, acquire and take assignment and delivery
of, the Borrower’s right, title and interest in and to the Specified Collateral, and shall accept payment of the Additional Consideration (or, in the case of an Applicable Transferee, its Ratable Share of the Specified Collateral and Additional
Consideration) pursuant to the Strict Foreclosure. For purposes of this Agreement and the Strict Foreclosure, the Collateral Agent and/or each Applicable Transferee that receives Specified Collateral in accordance with this clause (a) shall
each constitute a “Specified Collateral Recipient”. 
 (b) Each of the Debtors acknowledges and agrees that,
subject to payment of the Additional Consideration to the Applicable Transferee, upon the assignment, acquisition, delivery and/or transfer (as applicable) of the Specified Collateral as provided above, each Specified Collateral Recipient shall be
the sole owner of the relevant portion of the Specified Collateral transferred to it, and shall be entitled to all proceeds of such Specified Collateral of any kind whatsoever, and no Debtor or any Affiliate thereof or any other Person shall be
entitled to any such proceeds. Each of the Debtors shall hold, and shall cause each of its Affiliates to hold, for the benefit of and in trust for the Specified Collateral Recipients, all proceeds of the Specified Collateral of any kind whatsoever
received by it. Each Debtor shall, immediately following the receipt of any such proceeds by such Debtor or any of its Affiliates, remit (or procure and cause to be remitted) to the Specified Collateral Recipient such proceeds (or, with respect to
remittance to an Applicable Transferee, its Ratable Share thereof), and shall not commingle or permit the commingling of such proceeds with any other property of the Debtors or any other Person. 

(c) The parties hereby further acknowledge and agree that if, upon consummation of the Strict Foreclosure Transaction, any
Specified Collateral is registered in the name of the Collateral Agent, the Collateral Agent is hereby authorized by the Debtors (without the need for any further action or authorization) to take all actions and enter into any and all arrangements
deemed by the Collateral Agent (in its discretion or at the direction of any Applicable Transferee) to be reasonably necessary or desirable in order to render any 

  
 4 












 Applicable Transferee the legal owner of its Ratable Share of the Specified Collateral
(including to record and register such Specified Collateral in the name of such Applicable Transferee). Each Debtor hereby appoints the Collateral Agent as its
attorney-in-fact, with full power and authority to (x) sign or endorse such Debtor’s name on the Specified Collateral (or any portion thereof) and on such
other instruments or documents, in each case, to the extent the Collateral Agent (in its discretion or at the direction of any Applicable Transferee) deems the same to be reasonably necessary or desirable to create, establish, evidence, reflect,
maintain, protect and/or enforce (as the case may be) the Collateral Agent’s or any Applicable Transferee’s rights in any Specified Collateral, (y) take any other action to enforce this Agreement and/or exercise the Collateral
Agent’s or any Applicable Transferee’s rights in and to the Specified Collateral, and (z) collect or realize any proceeds of the Specified Collateral. 

(d) Without limiting anything else herein (including Section 6.8 hereof) or in the Loan Documents, in addition to any
other documents required to be delivered by it hereunder or in connection with the Strict Foreclosure Transactions, each Debtor hereby covenants and agrees to promptly deliver to the Collateral Agent or the relevant Applicable Transferee (as the
case may be), all information related to the Specified Collateral and Additional Consideration (and, if applicable to the Applicable Transferee, the portion of the Consent Premium due to it pursuant to the Transaction Support Agreement and/or the
Consent Agreement) that the Collateral Agent or such Applicable Transferee may reasonably request from time to time. 
 2.2
Compliance with the UCC. 
 (a) It is the express intent of the parties hereto that the Strict Foreclosure, including
the acceptance and transfer of the Specified Collateral thereunder and as otherwise contemplated by this Agreement, be consummated pursuant to, and shall constitute an “acceptance” of collateral in full satisfaction of the Obligations
(except any Surviving Obligations) in accordance with, and to the full extent required by, Sections 9-620, 9-621, 9-622 and any
other comparable provision of the UCC. Accordingly, upon the Effective Time, to the extent permitted under the UCC and applicable law, all Liens securing the Obligations shall be deemed to be fully released, and the Credit Agreement and the other
Loan Documents shall automatically terminate (except in the case of any provisions thereof that are expressed to survive any satisfaction, discharge, release or termination of the Obligations or Loan Document after giving effect to the Mutual
Release Agreement). 
 (b) Without limiting anything else, for all purposes under the UCC and other applicable law (including
the Securities Act of 1933) and the Loan Documents, and including to the extent necessary or desirable to effectuate the Strict Foreclosure in compliance with the requirements for a strict foreclosure pursuant to Sections 9-620, 9-621, 9-622 and each other comparable provision of the UCC, (i) each of the Collateral Agent and the Lenders shall be
deemed 

  
 5 












 pledgees of the Applicable Collateral, in each case, subject to the terms of the Loan
Documents, and (ii) acceptance of the Specified Collateral in connection with the Strict Foreclosure by the Collateral Agent (as agent for and on behalf of the Lenders pursuant to the Loan Documents) or by the Applicable Transferees in
accordance with the Loan Documents, shall, in each case, constitute “acceptance” of collateral by the pledgee for whose benefit the pledge was created, and shall have the same validity and legal force and effect, and, accordingly, shall
act as the “acceptance” required to validly and properly effectuate a strict foreclosure pursuant to the UCC, other applicable law and/or the Loan Documents. 

(c) The Debtors acknowledge and agree that this Agreement shall be deemed the Debtors’ acceptance and consent to strict
foreclosure over, and the Collateral Agent’s or Applicable Transferee’s (as applicable) acceptance of, the Specified Collateral in full satisfaction of the Obligations (except any Surviving Obligations), subject to the other terms and
conditions specified herein. 
 (d) Each Debtor (to the extent of any such right) hereby voluntarily: (i) waives any
right to receive a proposal of strict foreclosure pursuant to Section 9-620 of the UCC, (ii) acknowledges that its execution of this Agreement constitutes a “record authenticated after
default” for purposes of, and within the meaning of, Section 9-620(c)(2) of the UCC, (iii) agrees to fully cooperate with, and assist in, delivering, and in assigning or otherwise transferring
the ownership interests in, and title to, the Specified Collateral, to the Collateral Agent and/or any Applicable Transferee (as applicable), including by executing or delivering such further instruments or documents, or taking such further actions,
as are necessary or desirable to effectuate such transfer of ownership and title; (iv) acknowledges that the agreement by the Applicable Transferees and the Collateral Agent (as the case may be) to accept the Specified Collateral pursuant to
the Strict Foreclosure is subject to the terms of, and conditional upon satisfaction of all applicable conditions set forth in, this Agreement, the Transaction Support Agreement and the Loan Documents, (v) waives its right to notification of
disposition of the Specified Collateral under UCC Sections 9-611, 9-620 and 9-621 or other notification under other applicable
law, under the Loan Documents, (vi) waives any right to a public auction of the Specified Collateral to the highest bidder, (vii) waives any right to redeem the Specified Collateral under UCC
Section 9-623, the Loan Documents or otherwise, (viii) waives any right to any surplus value in the Specified Collateral under UCC Section 9-608, the Loan
Documents or otherwise, (ix) waives any right to object to the transactions contemplated by this Agreement, (x) waives any other rights under the UCC, the Loan Documents, whether legal or equitable, which it may possess in and to the
Specified Collateral and (xi) agrees that the transactions contemplated hereby are commercially reasonable.

4.5 Title; Rights; Claims.

 (d) As of ten (10) days before each Debtor’s acceptance of
this Agreement, (i) no secured party or lienholder (other than the Collateral Agent) held a security interest in, or other Lien, on any of the Specified Collateral, whether perfected by compliance with a statute, regulation, or treaty described
in Section 9-311(a) and other comparable provisions of the UCC, or otherwise and (ii) no secured party or lienholder (other than the Collateral Agent) held a security interest in, or other Lien on,

Time. 

  
 9 












 (b) Notice of the occurrence and continuance of the Existing Events of
Default has been properly and validly given to such Debtor by the Collateral Agent on behalf of the Secured Parties as required under the Loan Documents upon delivery of the Default and Acceleration Notice, and all other notices required to be
delivered and any and all other actions required to be taken in connection with the acceleration of the Obligations have been given or taken, as applicable, and, accordingly, the Obligations have been properly, validly and unconditionally
accelerated and declared to be forthwith due and payable in full in accordance with the Credit Agreement. Such Debtor shall not (and hereby irrevocably and unconditionally waives any right it may have to) contest or challenge the validity of the
Default and Acceleration Notice or any such other notice described above, or the matters set forth therein (including the acceleration of the Obligations provided for thereunder). Without limiting the foregoing, such Debtor agrees that, in addition
to any prior notices delivered by the Collateral Agent, this Agreement also constitutes any notice that may be given or required as a condition precedent to the Collateral Agent exercising any of its Enforcement Rights, and any and all grace or cure
periods are hereby irrevocably and unconditionally waived and relinquished by such Debtor. 
 (c) The outstanding Obligations
are due and payable in accordance with the terms of the Loan Documents, and are owed by such Debtor free of any offset, defense or counterclaim, and such Debtor will not (and hereby irrevocably and unconditionally waives any right it may have to)

6.7 Successors. This Agreement shall be binding upon, and inure to the benefit of, each of the parties hereto, and their
respective heirs, successors and assigns. 
 6.8 Further Assurances. Without limiting anything in Section 2, from
time to time, at the written request of another party hereto or of any Applicable Transferee, each party hereto shall (at the expense of the requesting party) execute and/or deliver (as applicable) such instruments, documents and agreements, and
take such actions, as, in each case, such requesting party may deem reasonably necessary or desirable in order to effectuate, evidence, reflect or record any of the Strict Foreclosure Transactions, and/or assure that the transfers, purposes and
objectives of this Agreement and the Strict Foreclosure Transactions are validly and fully accomplished. 
 6.9 Applicable
Transferee Agreements and Rights; No Other Implied Rights or Remedies. Each Applicable Transferee or other Person that, pursuant to the Strict Foreclosure, accepts any Specified Collateral or otherwise acquires any right, title or interest in or
to, any Specified Collateral, shall, by such acceptance or acquisition thereof, as applicable, be automatically and immediately deemed to have consented and agreed to the Strict Foreclosure (including the terms and manner of consummation thereof,
and actions and agreements of the Persons involved therein in connection with implementation thereof). Each Debtor agrees that each provision of this Agreement that grants or purports to grant any right or remedy to any Applicable Transferee, or
that otherwise requires any Debtor to take any action requested or required by, or comply with any instruction delivered by or on behalf of, any Applicable Transferee (including Section 2.1 and Section 6.8 of this Agreement) is intended
for the benefit of, and shall be directly enforceable against such Debtor by, such Applicable Transferee, notwithstanding that such Applicable Transferee shall not be a signatory hereto or direct party hereunder. Except as provided in the preceding
sentence, nothing herein is intended or shall be construed to confer upon or to give any person, firm, or corporation, other than the Collateral Agent and the Debtors, any rights or remedies under or by reason of this Agreement. 

6.10 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same agreement. Delivery of an executed counterpart of this Agreement by facsimile, email or other electronic means shall be equally as effective as delivery of an original executed
counterpart of this Agreement.

 6.11 Jurisdiction. The parties irrevocably and unconditionally submit
to and accept the exclusive jurisdiction of the United States District Court for the Southern District of New York located in the Borough of Manhattan or the courts of the State of New York located in the County of New York for any action, suit or
proceeding arising out of or based upon this Agreement or any matter relating to it and waive any objection that they may have to the laying of venue in any such court or that such court is an inconvenient forum or does not have personal
jurisdiction over them. 
 6.12 Avoidance. Notwithstanding any other provision of this Agreement, and including in the
event any Debtor becomes a debtor in a case under Title 11 of the United States Code (the “Bankruptcy Code”) subject to the Debtors’ rights under the Bankruptcy Code, in the event that any of the transactions contemplated
hereby (including the transfer of the Specified Collateral, or any part thereof) is subsequently rescinded, invalidated, voided, declared to be a fraudulent or preferential transfer or set aside, and/or any property transferred hereby is required to
be returned to a trustee, receiver or any other party, whether under any bankruptcy law, state or federal law, common law or equitable cause, or otherwise, then, the liabilities and obligations of the Debtors, the Credit Agreement, the Collateral
Agreement and the other Loan Documents, to the extent they remain unsatisfied under the terms of the Credit Agreement, the Collateral Agreement and the other Loan Documents, shall be revived and reinstated, and shall continue in full force and
effect until the Collateral Agent has received payment in full on such obligations, and the Debtors hereby agree to perform any and all acts and execute and deliver any and all further instruments that are necessary or required to ensure that the
Collateral Agent, for the benefit of the Secured Parties, has a first priority security interest in the Collateral to secure such obligations. The provisions of this Section 6.11 shall survive the Closing.
