 FIRST LIEN SECURITY AGREEMENT 
  
 SECURITY AGREEMENT dated March 31, 2005 made by Mustang MSC-Florida Acquisition, Inc., a Florida corporation (the
“Initial Borrower”), MSC-Medical Services Company, a Florida corporation (as the surviving entity of the Merger, the “Borrower”) and the other Persons listed on the signature pages hereof (the Borrower
and the Persons so listed being, collectively, the “Grantors”), to BANK OF AMERICA, N.A. (“Bank of America”), as administrative agent (in such capacity, together with any successor administrative agent
appointed pursuant to Article XI of the Revolving Credit Agreement (as hereinafter defined), the “Administrative Agent”) for the Secured Parties (as defined in the Revolving Credit Agreement). 
  
 PRELIMINARY STATEMENTS. 
  
 (1) The Initial Borrower has entered into a Revolving Credit Agreement dated
as of March 31, 2005 (as may be amended, amended and restated, supplemented or otherwise modified from time to time, being the “Revolving Credit Agreement”) with the Lenders, the L/C Issuer and the Administrative Agent
(each as defined therein). The Borrower has entered into an Assignment and Assumption Agreement dated as of March 31, 2005, under the terms of which the Borrower has agreed to assume all obligations of the Initial Borrower, effective upon
consummation of the Merger. 
  
 (2) Each Grantor is the owner of
the shares of stock or other Equity Interests (the “Initial Pledged Equity”) set forth opposite such Grantor’s name on and as otherwise described in Part I of Schedule I hereto and issued by the
Persons named therein and of the indebtedness (the “Initial Pledged Debt”) set forth opposite such Grantor’s name on and as otherwise described in Part II of Schedule I hereto and issued by the
obligors named therein. 
  
 (3) Each Grantor is the owner of the
deposit and other accounts (the “Initial Collateral Accounts”) with banks, in the name of such Grantor and subject to the terms of this Agreement, as set forth opposite such Grantor’s name on Schedule II hereto.

  
 (4) Upon the request of the Administrative Agent pursuant to
Section 2.03(g) of the Revolving Credit Agreement, the Borrower will open a blocked, non-interest bearing letter of credit cash collateral deposit account (the “L/C Cash Collateral Account”) with Bank of America
(or another commercial bank located in the United States, which has delivered a control agreement as contemplated by this Agreement or otherwise in form and substance reasonably satisfactory to the Administrative Agent), in the name of the
Administrative Agent and under the sole control and dominion of the Administrative Agent and subject to the terms of this Agreement. 
  
 (5) It is a condition precedent to the making of Revolving Credit Loans by the Lenders and the issuance of Letters of Credit by the L/C Issuer under the
Revolving Credit Agreement and the entry into Secured Swap Contracts by the Hedge Banks from time to time that the Grantors shall have granted the security interest contemplated by this Agreement. Each Grantor will derive substantial direct and
indirect benefit from the transactions contemplated by the Loan Documents.

 (6) Terms defined in the Revolving Credit Agreement and not otherwise defined in this Agreement are used
in this Agreement as defined in the Revolving Credit Agreement. Further, unless otherwise defined in this Agreement or in the Revolving Credit Agreement, terms defined in Article 8 or 9 of the UCC (as defined below) are used in this Agreement as
such terms are defined in such Article 8 or 9. “UCC” means the Uniform Commercial Code as in effect from time to time in the State of New York; provided, that, if perfection or the effect of perfection or
non-perfection or the priority of the security interest in any Collateral is governed by the Uniform Commercial Code as in effect in a jurisdiction other than the State of New York, “UCC” means the Uniform Commercial Code as
in effect from time to time in such other jurisdiction for purposes of the provisions hereof relating to such perfection, effect of perfection or non-perfection or priority. 
  
 NOW, THEREFORE, in consideration of the premises and in order to induce the Lenders to make Revolving Credit Loans and the
L/C Issuer to issue Letters of Credit under the Revolving Credit Agreement and to induce the Hedge Banks to enter into Secured Swap Contracts from time to time, each Grantor hereby agrees with the Administrative Agent for the ratable benefit of the
Secured Parties as follows:

to or otherwise with respect to any of the foregoing Collateral, and (B) cash. 
  
 Notwithstanding the foregoing provisions of this Section 1, with respect to each Grantor, in no event shall the security interest granted hereunder attach to any contract, license, permit or franchise to which such Grantor is a
party or any of its rights or interests thereunder, or any property or assets subject to any contract, license, permit or franchise, if and for so long as the grant of such security interest shall constitute or result in (x) the abandonment,
invalidation or unenforceability of any right, title or interest of such Grantor therein or (y) a breach or termination pursuant to the terms of, or a default under, any such contract, license, permit or franchise, except, in each case, to the
extent that any such term is rendered ineffective pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law or principles of equity;
provided, that notwithstanding the foregoing, such security interest shall attach immediately at such time as the condition causing such abandonment, invalidation or unenforceability shall be remedied and, to the extent severable, shall
attach immediately to any portion of such contract, license, permit or franchise, or property subject thereto, that does not result in any of the consequences specified in clause (x) or (y) above.

as to each Grantor, the payment of all amounts that constitute part of the Secured Obligations and would be owed by such Grantor to any Secured Party under the Loan Documents but for the fact that they are unenforceable or not allowable due to the
existence of a bankruptcy, reorganization or similar proceeding involving a Loan Party.

 Section 3. Grantors Remain Liable. Anything herein to the contrary notwithstanding, (a) each
Grantor shall remain liable under the contracts and agreements included in such Grantor’s Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been
executed, (b) the exercise by the Administrative Agent of any of the rights hereunder shall not release any Grantor from any of its duties or obligations under the contracts and agreements included in the Collateral and (c) no Secured
Party shall have any obligation or liability under the contracts and agreements included in the Collateral by reason of this Agreement or any other Loan Document, nor shall any Secured Party be obligated to perform any of the obligations or duties
of any Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder. 
  
 Section 4. Delivery and Control of Security Collateral. (a) All certificates or instruments representing or evidencing Security Collateral
shall be delivered to and held by or on behalf of the Administrative Agent pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form
and substance satisfactory to the Administrative Agent. The Administrative Agent shall have the right at any time to exchange certificates or instruments representing or evidencing Security Collateral for certificates or instruments of smaller or
larger denominations. 
  
 (b) With respect to any Security
Collateral that constitutes an uncertificated security, upon the request of the Administrative Agent, the relevant Grantor will cause the issuer thereof either (i) to register the Administrative Agent as the registered owner of such security or
(ii) to agree with such Grantor and the Administrative Agent that such issuer will comply with instructions with respect to such security originated by the Administrative Agent without further consent of such Grantor, such agreement to be in
form and substance satisfactory to the Administrative Agent (such agreement being an “Uncertificated Security Control Agreement”). 
  
 (c) With respect to any Security Collateral that constitutes a security entitlement as to which the financial institution acting as Administrative Agent
hereunder is not the securities intermediary, the relevant Grantor will cause the securities intermediary with respect to such security entitlement either (i) to identify in its records the Administrative Agent as the entitlement holder thereof
or (ii) to agree with such Grantor and the Administrative Agent that such securities intermediary will comply with entitlement orders originated by the Administrative Agent without further consent of such Grantor, such agreement to be in
substantially the form of Exhibit A hereto or otherwise in form and substance satisfactory to the Administrative Agent (a “Securities Account Control Agreement”). 
  
 (d) The Administrative Agent shall have the right, after the occurrence and
during the continuance of a Default under Section 8.01(a), (f) or (g) of the Revolving Credit Agreement or an Event of Default, at any time in its discretion and without notice to any Grantor, to transfer to or to register in
the name of the Administrative Agent or any of its nominees any or all of the Security Collateral, subject only to the revocable rights specified in Section 14(a). In addition, during the continuation of an Event of Default the
Administrative 

  

 MSC First Lien Security Agreement 
  
 7 








 
Agent shall have the right at any time to convert Security Collateral consisting of financial assets credited to the Securities Account to Security
Collateral consisting of financial assets held directly by the Administrative Agent, and to convert Security Collateral consisting of financial assets held directly by the Administrative Agent to Security Collateral consisting of financial assets
credited to the Securities Account. 
  
 (e) Upon the request of
the Administrative Agent, after the occurrence and during the continuance of a Default under Section 8.01(a), (f) or (g) of the Revolving Credit Agreement or an Event of Default, each Grantor will notify each issuer of Security
Collateral granted by it hereunder that such Security Collateral is subject to the security interest granted hereunder. 
  
 Section 5. Maintaining the Account Collateral. So long as any Revolving Credit Loan or any other Obligation of any Loan Party under any Loan
Document shall remain unpaid, any Letter of Credit shall be outstanding, any Secured Swap Contract shall be in effect or any Lender shall have any Commitment: 
  

(a) Each Grantor will maintain deposit and similar accounts only with the financial institution acting as Administrative Agent
hereunder or with a bank (a “Pledged Account Bank”) that has agreed with such Grantor and the Administrative Agent to comply with instructions originated by the Administrative Agent directing the disposition of funds in such
deposit account without the further consent of such Grantor, such agreement to be substantially in the form of Exhibit B hereto or otherwise in form and substance satisfactory to the Administrative Agent (a “Deposit Account
Control Agreement”; and, together with the Securities Account Control Agreements, the “Account Control Agreements”); provided, that this Section 5(a) shall not apply to any deposit
account operated solely as a payroll account. 
  
 (b) Each Grantor will immediately instruct each Person making payment by wire transfer obligated at any time to make any payment to such Grantor for any reason (an “Obligor”) to make such payment to a Collateral
Account, or, if such Obligor pays by check, such Grantor will promptly deposit such check into a Collateral Account in accordance with its cash management or treasury systems and policies. 
  
 (c) Upon any termination by a Grantor of any Collateral
Account, such Grantor will immediately (i) transfer all funds and property held in such terminated Collateral Account to another Collateral Account and (ii) notify all Obligors that were making payments to such Collateral Account to make
all future payments to another Collateral Account, in each case, so that the Administrative Agent shall have a continuously perfected security interest in such Account Collateral, funds and property. 
  
 (d) Each Grantor agrees to terminate any or all Collateral
Accounts, the L/C Cash Collateral Account and Account Control Agreements within a reasonable period of time following receipt of a written request by the Administrative Agent. 
  
 (e) The Administrative Agent shall have sole right to direct the disposition of funds with respect to the
L/C Cash Collateral Account; and it shall be a term and 

  

 MSC First Lien Security Agreement

condition of the L/C Cash Collateral Account, notwithstanding any term or condition to the contrary in any other agreement relating to the L/C Cash
Collateral Account, that no amount (including, without limitation, Cash Equivalents credited thereto) will be paid or released to or for the account of, or withdrawn by or for the account of, the Borrower or any other Person from the L/C Cash
Collateral Account except as required or permitted by the Loan Documents. 
  
 (f) The Grantors shall have the right to direct the disposition of funds with respect to, and any assets credited to, each of the Collateral Accounts (except the L/C Cash Collateral Account) on, and subject to, the
terms of the Account Control Agreement governing such Collateral Account except during the continuation of an Event of Default, in which case, the Administrative Agent may direct such disposition to the extent provided in the applicable Account
Control Agreement. 
  
 (g) During the
continuation of an Event of Default, the Administrative Agent may, at any time and without notice to, or consent from, any Grantor, transfer, or direct the transfer of, funds from the Collateral Accounts or the L/C Cash Collateral Account to satisfy
the Grantors’ obligations under the Loan Documents if an Event of Default shall have occurred and be continuing. 
  
 Section 6. Investing of Amounts in the L/C Cash Collateral Account. The Administrative Agent will, subject to the provisions of Sections 5,
7 and 22, from time to time (a) invest, or direct the applicable Pledged Account Bank to invest, amounts received with respect to the L/C Cash Collateral Account in such Cash Equivalents credited to the L/C Cash Collateral Account as the
Borrower may select and the Administrative Agent may approve, and (b) invest interest paid on the Cash Equivalents referred to in clause (a) above, and reinvest other proceeds of any such Cash Equivalents that may mature or be sold,
in each case in such Cash Equivalents credited in the same manner. Interest and proceeds that are not invested or reinvested in Cash Equivalents as provided above shall be deposited and held in the the L/C Cash Collateral Account. In addition, the
Administrative Agent shall have the right at any time to exchange, or direct the applicable Pledged Account Bank to exchange, such Cash Equivalents for similar Cash Equivalents of smaller or larger determinations, or for other Cash Equivalents,
credited to the L/C Cash Collateral Account. 
  
 Section 7.
Release of Amounts. So long as no Default shall have occurred and be continuing, the Administrative Agent will pay and release, or direct the applicable Pledged Account Bank to pay and release, to the applicable Grantor or at its order or, at
the request of such Grantor, to the Administrative Agent to be applied to the Obligations of the Grantors under the Loan Documents, such amount, if any, as is then on deposit in the L/C Cash Collateral Account to the extent (a) it
exceeds 105% of the aggregate of all outstanding L/C Obligations or (b) the L/C Obligations are no longer required to be Cash Collateralized under the terms of the Revolving Credit Agreement. 
  
 Section 8. Representations and Warranties. Each Grantor represents and
warrants as follows as of the Closing Date and as of each date on which quarterly supplements to the Schedules hereto are delivered to the Administrative Agent pursuant to Section 9(c): 
  
 (a) Such Grantor’s exact legal name, location, chief

will be released by the Administrative Agent to the applicable Grantor for the repair, replacement or restoration thereof, subject to such terms and conditions with respect to the release thereof as the Administrative Agent may reasonably require.
To the extent that (i) the amount of any such insurance payments exceeds the cost of any such repair, replacement or restoration, or (ii) such insurance payments are not otherwise required by the applicable Grantor to complete any such
repair, replacement or restoration required hereunder, such excess insurance proceeds will be applied to prepay the Outstanding Amount of Revolving Credit Loans to the extent required by the Revolving Credit Agreement, without any permanent
reduction in the Commitments, and any remaining amounts will be released to such Grantor unless a Default under Section 8.01(a), (f) or (g) of the Revolving Credit Agreement or any Event of Default shall have occurred and be
continuing, in which case the Administrative Agent will not be required to release the amount thereof to such Grantor and may hold or continue to hold such amount as additional security for the Secured Obligations of such Grantor. Upon the
occurrence and during the continuance of any Default or the actual or constructive total loss (in excess of $2,500,000 per occurrence) of any Equipment or Inventory, all insurance payments in respect of such Equipment or Inventory shall be paid to
the Administrative Agent and shall, in the Administrative Agent’s sole discretion, (i) be released to the applicable Grantor to be applied as set forth in the first sentence of this subsection (c) or (ii) be held as

will hold and preserve its records relating to the Collateral, including, without limitation, the Assigned Agreements and Related Contracts, and will permit representatives of the Administrative Agent at any time during normal business hours to
inspect and make abstracts from such records and other documents. If any Grantor does not have an organizational identification number and later obtains one, it will notify the Administrative Agent of such organizational identification number in the
quarterly supplements delivered pursuant to Section 9(c) for the fiscal quarter during which such organizational identification number was obtained. 
  

(b) Except as otherwise provided in this subsection (b), each Grantor will continue to collect, at its own expense, all amounts due or to become
due such Grantor under the Assigned Agreements, Receivables and Related Contracts. In connection with such collections, such Grantor may take (and, at the Administrative Agent’s direction, will take) such action as such Grantor or the
Administrative Agent may deem necessary or advisable to enforce collection of the Assigned Agreements, Receivables and Related Contracts; provided, that the Administrative Agent shall have the right at any time, upon the occurrence and
during the continuance of an Event of Default and upon written notice to such Grantor of its intention to do so, to notify the Obligors under any Assigned Agreements, Receivables and Related Contracts of the assignment of such Assigned Agreements,
Receivables and Related Contracts to the Administrative Agent and to direct such Obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the Administrative Agent and, upon such notification and at the
expense of such Grantor, to enforce collection of any such Assigned Agreements, Receivables and Related Contracts, to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have
done, and to otherwise exercise all rights with respect to such Assigned Agreements, Receivables and Related Contracts, including, without limitation, those set forth set forth in Section 9-607 of the UCC. After receipt by any Grantor of the
notice from the Administrative Agent referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including, without limitation, instruments) received by such Grantor in respect of the Assigned Agreements, Receivables and
Related Contracts of such Grantor shall be received in trust for the benefit of the Administrative Agent hereunder, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Administrative Agent in the same form as
so received (with any necessary indorsement) to be deposited in a Collateral Account and either (A) released to such Grantor on the terms set forth in Section 7 so long as no Default shall have occurred and be continuing or
(B) if any Default shall have occurred and be continuing, applied as provided in Section 22(b) and (ii) such Grantor will not adjust, settle or compromise the amount or payment of any Receivable or amount due on any Assigned
Agreement or Related Contract, release wholly or partly any Obligor thereof or allow any credit or discount thereon. No Grantor will permit or consent to the subordination of its right to payment under any of the Assigned Agreements, Receivables and
Related Contracts to any other indebtedness or obligations of the Obligor thereof.

Intellectual Property Collateral, or abandon any right to file an application for patent, trademark, or copyright, unless such Grantor shall have previously determined that such use or the pursuit or maintenance of such Intellectual Property
Collateral is no longer desirable in the conduct of such Grantor’s business and that the loss thereof would not be reasonably likely to have a Material Adverse Effect, in which case, such Grantor will give notice of any such abandonment to the
Administrative Agent in the quarterly supplements to the Schedules delivered pursuant to Section 9(c) for the fiscal quarter during which such Intellectual Property Collateral was so abandoned. 
  
 (b) Each Grantor shall use proper statutory notice in connection with its use
of each item of its Intellectual Property Collateral, except to the extent failure to do so could not reasonably be expected to have a Material Adverse Effect. Except as could not reasonably be expected to have a Material Adverse Effect, no Grantor
shall do or permit any act or knowingly omit to do any act whereby any of its Intellectual Property Collateral may lapse or become invalid or unenforceable or placed in the public domain. 
  
 (c) Each Grantor shall take all steps which it or the Administrative Agent deems reasonable and appropriate under the

with the quality of the products and services as of the date hereof, and taking all steps necessary to ensure that all licensed users of any of the Trademarks use such consistent standards of quality, except to the extent failure to do so could not
reasonably be expected to have a Material Adverse Effect.

 Section 18. Transfers and Other Liens; Additional Shares. (a) Each Grantor agrees that
it will not (i) Dispose of any of the Collateral, other than Dispositions of Collateral permitted under the terms of the Revolving Credit Agreement, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral
of such Grantor except for the pledge, assignment and security interest created under this Agreement and Liens permitted under the Revolving Credit Agreement. 
  

(b) Each Grantor agrees that it will (i) cause each issuer of the Pledged Equity pledged by such Grantor that is a Subsidiary of such Grantor not
to issue any Equity Interests or other securities in addition to or in substitution for the Pledged Equity issued by such issuer, except to such Grantor, and (ii) pledge hereunder, immediately upon its acquisition (directly or indirectly)
thereof, any and all additional Equity Interests or other securities. 
  
 Section 19. Administrative Agent Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints the Administrative Agent such Grantor’s attorney-in-fact, with full authority in the place and stead of such Grantor
and in the name of such Grantor or otherwise, from time to time, upon the occurrence and during the continuance of an Event of Default, in the Administrative Agent’s discretion, in accordance with and subject to the terms of this Agreement and
the other Loan Documents, to take any action and to execute any instrument that the Administrative Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation: 
  
 (a) to obtain and adjust insurance required to be paid to
the Administrative Agent pursuant to Section 11, 
  
 (b) to ask for, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, 
  
 (c) to receive, indorse and collect any drafts or other

the collection of any of the Collateral or otherwise to enforce compliance with the terms and conditions of any Assigned Agreement or the rights of the Administrative Agent with respect to any of the Collateral. 
  
 Section 20. Administrative Agent May Perform. Subject to the
terms of this Agreement, if any Grantor fails to perform any agreement contained herein, the Administrative Agent may, as the Administrative Agent deems necessary to protect the security interest granted hereunder in the Collateral or to protect the
value thereof, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the reasonable expenses of the Administrative Agent incurred in connection therewith shall be payable by such Grantor
under Section 23. 
  
 Section 21. The
Administrative Agent’s Duties. (a) The powers conferred on the Administrative Agent hereunder are solely to protect the Secured Parties’ interest in the 

  

 MSC First Lien Security Agreement 
  
 21 








 
Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Administrative Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters
relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The
Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property.

  
 (b) Anything contained herein to the contrary notwithstanding,
the Administrative Agent may from time to time, when the Administrative Agent deems it to be necessary, appoint one or more subagents (each a “Subagent”) for the Administrative Agent hereunder with respect to all or any part
of the Collateral. In the event that the Administrative Agent so appoints any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Grantor
hereunder shall be deemed for purposes of this Security Agreement to have been made to such Subagent, in addition to the Administrative Agent, for the ratable benefit of the Secured Parties, as security for the Secured Obligations of such Grantor,
(ii) such Subagent shall automatically be vested, in addition to the Administrative Agent, with all rights, powers, privileges, interests and remedies of the Administrative Agent hereunder with respect to such Collateral, and (iii) the
term “Administrative Agent,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Administrative Agent with respect to such Collateral, shall include such Subagent; provided, that no
such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Administrative Agent. 
  
 Section 22. Remedies. If any Event of Default shall have occurred and be continuing: 
  
 (a) The Administrative Agent may exercise in respect of the
Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also
may: (i) require each Grantor to, and each Grantor hereby agrees that it will at its expense and upon request of the Administrative Agent forthwith, assemble all or part of the Collateral as directed by the Administrative Agent and make it
available to the Administrative Agent at a place and time to be designated by the Administrative Agent that is reasonably convenient to both parties; (ii) without notice except as specified below, sell the Collateral or any part thereof in one
or more parcels at public or private sale, at any of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Administrative Agent may deem commercially reasonable;
(iii) occupy any premises owned or leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation
to such Grantor in respect of such occupation; and (iv) exercise any and all rights and remedies of any of the Grantors under 

  

 MSC First Lien Security Agreement 
  
 22 








 
or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, (A) any and all rights of such Grantor
to demand or otherwise require payment of any amount under, or performance of any provision of, the Assigned Agreements, the Receivables, the Related Contracts and the other Collateral, (B) withdraw, or cause or direct the withdrawal, of all
funds with respect to the Account Collateral and (C) exercise all other rights and remedies with respect to the Assigned Agreements, the Receivables, the Related Contracts and the other Collateral, including, without limitation, those set forth
in Section 9-607 of the UCC. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to
be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. 
  
 (b) Any cash held by or on behalf of the Administrative Agent and all cash proceeds received by or on behalf
of the Administrative Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Administrative Agent, be held by the Administrative Agent as collateral for, and/or
then or at any time thereafter applied (after payment of any amounts payable to the Administrative Agent pursuant to Section 23) in whole or in part by the Administrative Agent for the ratable benefit of the Secured Parties against, all
or any part of the Secured Obligations, as set forth in Section 8.03 of the Revolving Credit Agreement. 
  
 (c) All payments received by any Grantor under or in connection with any Assigned Agreement or otherwise in respect of the Collateral
shall be received in trust for the benefit of the Administrative Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Administrative Agent in the same form as so received (with any necessary
indorsement). 
  
 (d) The Administrative Agent
may, without notice to any Grantor except as required by law and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Secured Obligations against any funds held with respect to the Account Collateral or in any
other deposit account. 
  
 (e) The Administrative
Agent may send to each bank, securities intermediary or issuer party to any Account Control Agreement, or Uncertificated Security Control Agreement a “Notice of Exclusive Control” as defined in and under such Agreement. 
  
 (f) In the event of any sale or other disposition of any of
the Intellectual Property Collateral of any Grantor, the goodwill symbolized by any Trademarks subject to such sale or other disposition shall be included therein, and such Grantor shall supply to the Administrative Agent or its designee such
Grantor’s know-how and expertise, and documents and things relating to any Intellectual Property Collateral subject to such sale or other disposition, and, subject to applicable law, such Grantor’s customer lists and 

  

 MSC First Lien Security Agreement 
  
 23 








 
other records and documents relating to such Intellectual Property Collateral and to the manufacture, distribution, advertising and sale of products and
services of such Grantor. 
  
 Section 23. Indemnity and
Expenses. (a) Each Grantor agrees to indemnify, defend and save and hold harmless each Secured Party and each of their Affiliates and their respective officers, directors, employees, agents and advisors (each, an “Indemnified
Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and reasonable out-of-pocket expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by
or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Agreement (including, without limitation, enforcement of this Agreement), except to the extent such claim, damage, loss,
liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. 
  
 (b) Each Grantor will upon demand pay to the Administrative Agent the amount
of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of its counsel and of any experts and agents, that the Administrative Agent may incur in connection with (i) the administration of this
Agreement, (ii) the custody, preservation, use or operation of, or the sale of, collection from or other realization upon, any of the Collateral of such Grantor, (iii) the exercise or enforcement of any of the rights of the Administrative
Agent or the other Secured Parties hereunder or (iv) the failure by such Grantor to perform or observe any of the provisions hereof. 
  
 Section 24. Amendments; Waivers; Additional Grantors; Etc. (a) No amendment or waiver of any provision of this Agreement, and no
consent to any departure by any Grantor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Administrative Agent, and then such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. No failure on the part of the Administrative Agent or any other Secured Party to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. 
  
 (b) Upon the execution and delivery by any Person of a security agreement supplement in substantially the form of Exhibit F hereto (each a
“Security Agreement Supplement”), such Person shall be referred to as an “Additional Grantor” and shall be and become a Grantor hereunder, and each reference in this Agreement and the other Loan
Documents to “Grantor” shall also mean and be a reference to such Additional Grantor, each reference in this Agreement and the other Loan Documents to the “Collateral” shall also mean and be a reference to the Collateral granted
by such Additional Grantor and each reference in this Agreement to a Schedule shall also mean and be a reference to the schedules attached to such Security Agreement Supplement. 
  
 Section 25. Notices, Etc. All notices and other communications provided for hereunder shall be in accordance
with, and with the same effect as provided in, Section 11.02 of the Revolving Credit Agreement, the provisions of which Section are incorporated by reference hereto, provided, that in the case of each Grantor other

Administrative Agent hereunder, to the benefit of the Secured Parties and their respective successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), any Lender may assign or otherwise transfer all
or any portion of its rights and obligations under the Revolving Credit Agreement (including, without limitation, all or any portion of its Commitment, the Revolving Credit Loans owing to it and the Revolving Credit Note, if any, held by it) to any
other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Lender herein or otherwise, in each case as provided in Section 11.06 of the Revolving Credit Agreement.

effect that the transaction is in compliance with the Loan Documents and as to such other matters as the Administrative Agent may request.

                            , a

“Securities Intermediary”). 
  
 PRELIMINARY STATEMENTS: 
  
 (1) The Grantor has granted
the Secured Party a security interest (the “Security Interest”) in account no.
                                 maintained by the Securities Intermediary for the

contained herein, the parties hereto hereby agree as follows: 
  
 SECTION 1. The Account. The Grantor and Securities Intermediary represent and warrant to, and agree with, the Grantor and the Secured Party that:

Section 8-110(e) of the UCC so long as the Security Interest shall remain in effect.

 (e) The Grantor and Securities Intermediary do not know of
any claim to or interest in the Account or any property credited to the Account, except for claims and interests of the parties referred to in this Agreement. 
  

 MSC First Lien Security Agreement 








 SECTION 2. Control by Secured Party. The Securities Intermediary will comply with all
notifications it receives directing it to transfer or redeem any property in the Account (each an “Entitlement Order”) or other directions concerning the Account (including, without limitation, directions to distribute to the
Secured Party proceeds of any such transfer or redemption or interest or dividends on property in the Account) originated by the Secured Party without further consent by the Grantor or any other person. 
  
 SECTION 3. Grantor’s Rights in Account. 
  
 (a) Except as otherwise provided in this Section 3, the
Securities Intermediary will comply with Entitlement Orders originated by the Grantor without further consent by the Secured Party. 
  
 (b) Until the Securities Intermediary receives a notice from the Secured Party that the Secured Party will exercise exclusive control over the Account (a
“Notice of Exclusive Control”), the Securities Intermediary may distribute to the Grantor all interest and regular cash dividends on property in the Account. 
  
 (c) If the Securities Intermediary receives from the Secured Party a Notice of Exclusive Control, the Securities
Intermediary will cease: 
  
 (i) complying with
Entitlement Orders or other directions concerning the Account originated by the Grantor and 
  
 (ii) distributing to the Grantor interest and dividends on property in the Account. 
  
 SECTION 4. Priority of Secured Party’s Security Interest.
(a) The Securities Intermediary subordinates in favor of the Secured Party any security interest, lien, or right of setoff it may have, now or in the future, against the Account or property in the Account, except that the Securities

interest.

withdrawal, delivery, or payment in violation of Section 3, the Securities Intermediary will not be liable to the Secured Party for complying with Entitlement Orders or other directions concerning the Account from the Grantor that are
received by the Securities Intermediary before the Securities Intermediary receives and has a reasonable opportunity to act on a Notice of Exclusive Control. 
  
 (b) The Securities Intermediary will not be liable to the Grantor or the Secured Party for complying with a Notice of Exclusive Control or with an
Entitlement Order or other direction concerning the Account originated by the Secured Party, even if the Grantor notifies the Securities Intermediary that the Secured Party is not legally entitled to issue the Notice of Exclusive Control or
Entitlement Order or such other direction unless the Securities Intermediary takes the action after it is served with an injunction, restraining order, or other legal process enjoining it from doing so, issued by a court of competent jurisdiction,
and had a reasonable opportunity to act on the injunction, restraining order or other legal process. 
  
 (c) This Agreement does not create any obligation of the Securities Intermediary except for those expressly set forth in this Agreement and in Part 5 of
Article 8 of the N.Y. Uniform Commercial Code. In particular, the Securities Intermediary need not investigate whether the Secured Party is entitled under the Secured Party’s agreements with the Grantor to give an Entitlement Order or other
direction concerning the Account or a Notice of Exclusive Control. The Securities Intermediary may rely on notices and communications it believes given by the appropriate party. 
  
 SECTION 7. Indemnity. The Grantor will indemnify the Securities Intermediary, its officers, directors, employees and
agents against claims, liabilities and expenses arising out of this Agreement (including, without limitation, reasonable attorney’s fees and disbursements), except to the extent the claims, liabilities or expenses are caused by the Securities
Intermediary’s gross negligence or willful misconduct as found by a court of competent jurisdiction in a final, non-appealable judgment.

 (b) The Securities Intermediary may terminate this Agreement on 60 days’ prior notice to the Secured Party and the Grantor, provided
that before such termination the Securities Intermediary and the Grantor shall make arrangements to transfer the property in the Account to another securities intermediary that shall have executed, together with the Grantor, a control agreement in
favor of the Secured Party in respect of such property in substantially the form of this Agreement or otherwise in form and substance satisfactory to the Secured Party. 
  
 (c) Sections 6 and 7 will survive termination of this Agreement.

governed by the law of the State of New York. The Securities Intermediary and the Grantor may not change the law governing the Account without the Secured Party’s express prior written agreement.

 SECTION 12. Financial Assets. The Securities Intermediary agrees with
the Secured Party and the Grantor that, to the fullest extent permitted by applicable law, all property credited from time to time to the Account will be treated as financial assets under Article 8 of the N.Y. Uniform Commercial Code.

this Agreement will be in writing (except that Entitlement Orders may be given orally), will be sent to the party’s address set forth under its name below or to such other address as the party may notify the other parties and will be effective

 (ii) distributing to the Grantor interest and dividends on property (including, without limitation, funds and financial assets) in such
Account.

security interest or lien, and (C) may exercise any right of recoupment or setoff against any Account, in the case of clauses (A), (B) and (C) above, to secure or to satisfy, and only to secure or to satisfy, payment
(x) for such property, (y) for its customary fees and expenses for the routine maintenance and operation of such Account, and (z) if such Account is a deposit account, for the face amount of any items that have been credited to such

Exclusive Control. 
  
 (b) The Account Holder will not be liable
to the Grantor or the Secured Party for complying with a Notice of Exclusive Control or with an Account Direction or other direction concerning any Account originated by the Secured Party, even if the Grantor notifies the Account Holder that the
Secured Party is not legally entitled to issue the Notice of Exclusive Control or Account Direction or such other direction unless the Account Holder takes the action after it is served with an injunction, restraining order, or other legal process
enjoining it from doing so, issued by a court of competent jurisdiction, and had a reasonable opportunity to act on the injunction, restraining order or other legal process. 
  
 (c) This Agreement does not create any obligation of the Account Holder except for those expressly set forth in this
Agreement and, in the case of any Account that is a securities account, in Part 5 of Article 8 of the N.Y. Uniform Commercial Code and, in the case of any Account that is a deposit account, in Article 4 of the N.Y. Uniform Commercial Code. In
particular, the Account Holder need not investigate whether the Secured Party is entitled under the Secured Party’s agreements with the Grantor to give an Account Direction or other direction concerning any Account or a Notice of Exclusive
Control. The Account Holder may rely on notices and communications it believes given by the appropriate party. 
  
 SECTION 7. Indemnity. The Grantor will indemnify the Account Holder, its officers, directors, employees and agents against claims, liabilities and
expenses arising out of this Agreement (including, without limitation, reasonable attorney’s fees and disbursements), except to the extent the claims, liabilities or expenses are caused by the Account Holder’s gross negligence or willful
misconduct as found by a court of competent jurisdiction in a final, non-appealable judgment.

Interest has terminated, this Agreement will immediately terminate. 
  
 (b) The Account Holder may terminate this Agreement on 60 days’ prior notice to the Secured Party and the Grantor, provided that before such termination the Account Holder and the Grantor shall make arrangements to
transfer the property (including, without limitation, all funds and financial assets) credited to each Account to another Account Holder that shall have executed, together with the Grantor, a control agreement in favor of the Secured Party in
respect of such property in substantially the form of this Agreement or otherwise in form and substance satisfactory to the Secured Party. 
  
 (c) Sections 6 and 7 will survive termination of this Agreement. 
  
 SECTION 9. Governing Law. This Agreement and each Account will be governed by the law of the State of New York. The
Account Holder and the Grantor may not change the law governing any Account without the Secured Party’s express prior written agreement.

interest therein would impair the validity or enforceability 

  

 MSC First Lien Security Agreement 








 
of such intent-to-use trademark applications under applicable federal law), together with the goodwill symbolized thereby (the

Schedule III hereto), Account Collateral (including, without limitation, the deposit accounts set forth on Schedule IV hereto), Intellectual
Property Collateral, Commercial Tort Claims Collateral (including, without limitation, the commercial tort claims described in Schedule V hereto), all books and records (including, without limitation, subject to applicable law, customer

and payable with respect to, and supporting obligations relating to, any and all of the undersigned’s Collateral (including, without limitation, proceeds, collateral and supporting obligations that constitute property of the types described in
this Section 1) and, to the extent not otherwise included, all (A) payments under insurance (whether or not the Administrative Agent is the loss payee thereof), or any indemnity, warranty or guaranty, payable by reason of loss or
damage to or otherwise with respect to any of the foregoing Collateral, and (B) cash. 
  
 Notwithstanding the foregoing provisions of this Section 1, in no event shall the security interest granted hereunder attach to any contract, license, permit or franchise to which the undersigned is a
party or any of its rights or interests thereunder, or any property or assets subject to any contract, license, permit or franchise, if and for so long as the grant of such security interest shall constitute or result in (x) the abandonment,
invalidation or unenforceability of any right, title or interest of the undersigned therein or (y) a breach or termination pursuant to the terms of, or a default under, any such contract, license, permit or franchise, except, in each case, to
the extent that any such term would be rendered ineffective pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law or principles of equity;
provided, that notwithstanding the foregoing, such security interest shall attach immediately at such time as the condition causing such abandonment, invalidation or unenforceability shall be remedied and, to the extent severable, shall
attach immediately to any portion of such contract, license, permit or franchise, or property subject thereto, that does not result in any of the consequences specified in clause (x) or (y) above. 
  
 SECTION 2. Security for Obligations. The grant of a security interest

indirect, absolute or contingent, and whether for principal, reimbursement obligations, interest, premiums, penalties, fees, indemnifications, contract causes of action, costs, expenses or otherwise. Without limiting the generality of the foregoing,
this Security Agreement Supplement and the Security Agreement secures the payment of all amounts that constitute part of the Secured Obligations and that would be owed by the undersigned to any Secured Party under the Loan Documents but for the fact
that such Secured Obligations are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving a Loan Party.

executive office, type of organization, jurisdiction of organization and organizational identification number is set forth in Schedule VI hereto. The undersigned has no trade names other than as listed on Schedule IV hereto.

all of the terms and provisions of the Security Agreement to the same extent as each of the other Grantors. The undersigned further agrees, as of the date first above written, that each reference in the Security Agreement to an “Additional
Grantor” or a “Grantor” shall also mean and be a reference to the undersigned, that each reference to the “Collateral” or any part thereof shall also mean and be a reference to the undersigned’s Collateral or part
thereof, as the case may be, and that each reference in the Security Agreement to a Schedule shall also mean and be a reference to the schedules attached hereto. 
  
 SECTION 5. Governing Law. This Security Agreement Supplement shall be governed by, and construed in accordance with,
the laws of the State of New York.
