2.3Payment of Interest on the Credit Extensions.

(a)Interest Rate. Subject to Section 2.3(b), the principal amount outstanding under the Term Loan shall accrue interest at a fixed per annum rate (which rate shall be fixed for the duration of such Term Loan) equal to eleven and one-half percent (11.50%) per annum, which interest shall be payable quarterly in arrears commencing with the Payment Date of the first calendar quarter to occur after the Closing Date in accordance with Section 2.3(c). Interest shall accrue on the Term Loan commencing on, and including, the Closing Date, and shall accrue on the Term Loan, or any portion thereof, for the day on which the Term Loan or such portion is actually paid. Interest shall be computed on the basis of a year of 360 days and the actual number of days elapsed.

(b)Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default (and without notice to Borrower or demand by Lender for payment thereof), the Obligations shall bear interest at a rate per annum which is three percentage points (3.00%) above the rate that is otherwise applicable thereto (the “Default Rate”), and such interest shall be payable entirely in cash on demand of Lender; provided, that, absent payment of such interest at the Default Rate when due, such Default Rate interest shall be capitalized on the last day of each fiscal month and such capitalized amount shall be added to the then-outstanding principal amount of the Term Loan and constitute outstanding principal for all purposes hereof. Payment, capitalization or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Lender.

(c)Payments. Except as otherwise expressly provided herein, all loan payments by Borrower hereunder shall be made to such bank account of Lender as Lender may designate by notice from time to time to Borrower on the date specified herein. Unless otherwise provided, interest is payable quarterly on the Payment Date of each calendar quarter. Payments of principal or interest received after 2:00 p.m. on such date are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue until paid. All payments to be made by Borrower hereunder or under any other Loan Document, including payments of principal and interest made hereunder and pursuant to any other Loan Document, and all fees, expenses, indemnities and reimbursements, shall be made without set-off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds.

2.4Expenses. Borrower shall pay to Lender, all Lender Expenses incurred through and after the Effective Date, upon demand.

2.5Taxes; Withholding, etc.

(a)All sums payable by any Credit Party hereunder and under the other Loan Documents shall (except to the extent required by Requirements of Law) be paid free and clear of, and without any deduction or withholding on account of, any Tax imposed, levied, collected, withheld or assessed by or within the United States of America or any political subdivision in or of the United States of America or any other jurisdiction from or to which a payment is made by

or on behalf of any Credit Party or by any federation or organization of which the United States of America or any such jurisdiction is a member at the time of payment. In addition, Borrower agrees to pay, and shall indemnify and hold Lender harmless from, all present or future stamp, court or documentary, recording or filing Taxes or similar levies or Taxes which arise (i) from any payment made hereunder, (ii) from the execution, delivery, performance, enforcement or registration of any Loan Document, (iii) from the receipt or perfection of a security interest under any Loan Document, or (iv) otherwise with respect to any Loan Document, and within thirty (30) days after the date of paying such sum, Borrower shall furnish to Lender the original or a certified copy of a receipt evidencing payment thereof.

(b)If any Credit Party or any other Person is required by Requirements of Law to make any deduction or withholding on account of any Tax from any sum paid or payable by any Credit Party to Lender under any of the Loan Documents: (i) Borrower shall notify Lender of any such requirement or any change in any such requirement as soon as any Borrower becomes aware of it; (ii) Borrower shall pay any such Tax before the date on which penalties attach thereto, such payment to be made (if the liability to pay is imposed on any Credit Party) for its own account or (if that liability is imposed on Lender, as the case may be) on behalf of and in the name of Lender; and (iii) within thirty (30) days after paying any sum from which it is required by Requirements of Law to make any deduction or withholding, and within thirty (30) days after the due date of payment of any Tax which it is required by clause (ii) above to pay, Borrower shall deliver to Lender evidence satisfactory to Lender of such deduction, withholding or payment and of the remittance thereof to the relevant taxing or other Governmental Authority.

(c)Lender (and any of its successors or assigns) shall deliver to Borrower on or prior to the Effective Date, such properly completed and executed documentation reasonably requested by Borrower as will permit payments to be made hereunder and under any other Loan Documents without withholding or at a reduced rate of withholding. In addition, Lender (and any of its successors or assigns) shall, if reasonably requested by Borrower, deliver such other documentation prescribed by Requirements of Law or reasonably requested by Borrower as will enable Borrower to determine whether or not Lender (or its successors or assigns) is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, on or prior to the Effective Date, Lender shall provide to Borrower the appropriate IRS Form W-8, with any supporting information required, establishing that Lender is exempt from U.S. withholding tax on payments made hereunder and under any other Loan Documents. Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Borrower in writing of its legal inability to do so. In furtherance of the foregoing, each Credit Party and Lender agree that, absent a change in Requirements of Law, provided that Lender provides the foregoing forms and documentation and through those forms and documentation establishes that it not subject to withholding tax under Requirements of Law, including FATCA, then any sum payable hereunder and under the other Loan Documents will not be subject to deduction by or withheld upon for U.S. Taxes by any Credit Party under this Section 2.5.

2.6Facility Fee. As additional consideration for Lender’s agreement to advance money or extend credit for Borrower’s benefit on the terms and conditions set forth in this Agreement, Borrower shall pay to Lender on the Effective Date the amount of Three Hundred and Seventy-five Thousand Dollars ($375,000.00), which shall amount shall not be refundable, in whole or in part, for any reason (including, for the avoidance of doubt, the termination of this Agreement and any obligation of Lender to make the Term Loan hereunder pursuant to the ultimate sentence of Section 3.4).

2.7Register; Term Loan Note.

(a)Register. Lender shall maintain at its principal office (as specified in, or as otherwise identified upon notice to the other parties hereto in accordance with, Section 10), a register for the recordation of the name and address of Lender, the principal of, and stated interest on, the Term Loan and the Term Loan Note held by Lender (the “Register”). The Register shall be available for inspection by Borrower at any reasonable time and from time to time upon reasonable prior notice. Lender shall record, or shall cause to be recorded, in the Register the principal of, and interest on, the Term Loan, and each repayment or prepayment in respect of the principal amount of the Term Loan and any such recordation shall be conclusive and binding on Borrower and Lender, absent manifest error; provided, that failure to make any such recordation, or any error in such recordation, shall not affect any of Borrower’s Obligations in respect of the Term Loan; provided further, that in the event of any inconsistency between the Register and Lender’s records, the recordations in the Register shall govern, absent manifest error. Borrower hereby designates Lender to serve as Borrower’s agent solely for purposes of maintaining the Register as provided in this Section 2.8.

(b)Term Loan Note. Borrower shall execute and deliver to Lender or, if applicable and if so specified in such notice, to any Person who is an assignee of such Lender pursuant to Section 12.1, on the Closing Date a Term Loan Note to evidence the Term Loan.

(b)If this Agreement is terminated, Lender’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash.

At the request of any Credit Party following any such termination of Lender’s obligations to make Credit Extensions, Lender shall deliver to such Credit Party any Collateral of such Credit Party held by Lender hereunder and execute and deliver to such Credit Party such documents as such Credit Party shall reasonably request to evidence such termination.

8.11Indenture. An Event of Default (as such term is defined in the Indenture) (a) without limiting the generality of Section 8.4, specified in Section 6.01(e) or Section 6.01(f) of the Indenture with respect to Borrower occurs; or (b) otherwise occurs and is continuing.

9.	RIGHTS AND REMEDIES UPON AN EVENT OF DEFAULT

9.1Rights and Remedies. While an Event of Default occurs and continues, Lender may, without notice or demand:

(a)declare all Obligations (including, for the avoidance of doubt, the Makewhole Amount) immediately due and payable (but if an Event of Default described in Section 8.4 occurs all Obligations, including the Makewhole Amount, are automatically and immediately due and payable without any action by Lender), whereupon all Obligations for principal, interest, premium or otherwise (including, for the avoidance of doubt, the Makewhole Amount) shall become due and payable by Borrower without presentment, demand, protest or other notice of any kind, which are all expressly waived by the Credit Parties hereby;

(b)settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Lender considers advisable, notify any Person owing Borrower money of Lender’s security interest in such funds, and verify the amount of such account;

(c)make any payments and do any acts it considers necessary or reasonable to protect the Collateral or its security interest in the Collateral. Borrower shall assemble the Collateral if Lender requests and make it available as Lender designates. Lender may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower hereby grants Lender a license to enter and occupy any of their premises, without charge, to exercise any of Lender’s rights or remedies;

(d)apply to the Obligations (i) any balances and deposits of Borrower it holds, or (ii) any amount held by Lender owing to or for the credit or the account of Borrower;

(e)ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Subject to the Intercreditor Agreement, Lender is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, Patents, copyrights, mask works, rights of use of any name, trade names, trademarks, know-how and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Lender’s exercise of its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Lender’s benefit;

(f)place a “hold” on any account maintained with Lender or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral;

(g)demand and receive possession of Borrower’s Books regarding Collateral; and

(h)subject to the Intercreditor Agreement, exercise all rights and remedies available to Lender under the Collateral Documents or any other Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

9.2Power of Attorney. Borrower hereby irrevocably appoints Lender as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to, as applicable: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b) sign Borrower’s name on any invoice or ▇▇▇▇ of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Lender determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Lender or a third Person as the Code permits. Borrower hereby appoints Lender as its lawful attorney-in-fact to file or record any documents necessary to perfect or continue the perfection of Lender’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than inchoate indemnity obligations) have been satisfied in full. Lender’s foregoing appointment as Borrower’s attorney in fact, and all of Lender’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed.

9.3Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Lender may obtain such insurance or make such payment, and all amounts so paid by Lender are Lender Expenses and immediately due and payable, bearing interest at the rate applicable to the Obligations, and secured by the Collateral. Lender will make reasonable efforts to provide Borrower with notice of Lender obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Lender are deemed an agreement to make similar payments in the future or Lender’s waiver of any Event of Default.

9.4Application of Payments and Proceeds upon Default. If an Event of Default has occurred and is continuing, Lender shall apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Lender shall determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Lender for any deficiency. If Lender directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Lender shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Lender of cash therefor.

9.5Lender’s Liability for Collateral. So long as Lender complies with Requirements of Law regarding the safekeeping of the Collateral in the possession or under the control of Lender, Lender shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; or (c) any act or default of any carrier, landlord, warehouseman, bailee, agent, processor or other Person. In no event shall Lender have any liability for any diminution in the value of the Collateral for any reason. Borrower bears all risk of loss, damage or destruction of the Collateral.

9.6No Waiver; Remedies Cumulative. Lender’s failure, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Lender thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by the party granting the waiver and then is only effective for the specific instance and purpose for which it is given. Lender’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Lender has all rights and remedies provided under the Code, by law, or in equity. Lender’s exercise of one right or remedy is not an election and shall not preclude Lender from exercising any other remedy under this Agreement or other remedy available at law or in equity, and Lender’s waiver of any Event of Default is not a continuing waiver. Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence.

9.7Demand Waiver; Makewhole Amount. Other than notices expressly required by the Loan Documents or by Requirements of Law, Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Lender on which Borrower is liable. Borrower acknowledges and agrees that the Makewhole Amount shall be due and payable by Borrower upon the acceleration of the Obligations pursuant to Section 9.1(a), whether such acceleration is automatic or is effected by Lender’s declaration thereof, as provided in Section 9.1(a), and Borrower waives any right to object thereto in any voluntary or involuntary bankruptcy, insolvency or similar proceeding or otherwise.

11.	CHOICE OF LAW, VENUE, AND JURY TRIAL WAIVER

New York law governs the Loan Documents without regard to principles of conflicts of law. Credit Parties and Lender each submit to the exclusive jurisdiction of the courts of the State of New York sitting in New York County, and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by Requirements of Law, in such Federal court; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Lender from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Lender. Each Credit Party expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and each Credit Party hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Each Credit Party hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to such Credit Party at the address set forth in Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of such Credit Party’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, CREDIT PARTIES AND LENDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR ALL PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

12.	GENERAL PROVISIONS

12.1Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. No Credit Party may transfer, pledge or assign this Agreement or any other Loan Document or any rights or obligations under hereunder or thereunder without Lender’s prior written consent. Lender may sell, transfer, assign, pledge, negotiate, or grant participation in (any such sale, transfer, assignment, negotiation, or grant of a participation, a “Lender Transfer”) all or any part of, or any interest in, Lender’s obligations, rights, and benefits under this Agreement and the other Loan Documents to any Person; provided, however, that no Lender Transfer shall be made to a Person that derives more than fifty percent (50.0%) of its net revenues, on a consolidated basis, from the sale of pharmaceutical products.

12.2Indemnification; Costs and Expenses.

(a)Borrower agrees to indemnify and hold harmless Lender and each manager, partner, director, officer, employee, agent, attorney and affiliate thereof (each such person, an “Indemnified Person”) from and against any and all Indemnified Liabilities; provided, that (i) no Credit Party shall have any obligation to any Indemnified Person hereunder with respect to any Indemnified Liabilities (x) to the extent such Indemnified Liabilities arise from the gross negligence, bad faith or willful misconduct of that Indemnified Person, in each case, as determined by a final, non-appealable judgment of a court of competent jurisdiction or (y) to the extent such Indemnified Liabilities resulted solely from disputes between or among Indemnified Persons, and (ii) no Credit Party shall be liable for any settlement of any claim or proceeding effected by any Indemnified Person without the prior written consent of such Credit Party (which consent shall not be unreasonably withheld or delayed), but if settled with such consent or if there shall be a final judgment against an Indemnified Person, each of the Credit Parties shall indemnify and hold harmless such Indemnified Person from and against any loss or liability by reason of such settlement or judgment in the manner set forth in this Agreement.

(b)To the extent permitted by Requirements of Law, no Credit Party shall assert, and each Credit Party hereby waives, any claim against Lender and its Affiliates, directors, employees, attorneys, agents or sub-agents, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) (whether or not the claim therefor is based on contract, tort or duty imposed by any applicable legal requirement) arising out of, in connection with, arising out of, as a result of, or in any way related to, this Agreement or any Loan Document or any agreement or instrument contemplated hereby or thereby or referred to herein or therein, the transactions contemplated hereby or thereby, the Term Loan or the use of the proceeds thereof or any act or omission or event occurring in connection therewith, and each Credit Party hereby waives, releases and agrees not to ▇▇▇ upon any such claim or any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

(c)Any action taken by any Credit Party under or with respect to any Loan Document, even if required under any Loan Document or at the request of Lender, shall be at the expense of such Credit Party, and no Secured Party shall be required under any Loan Document to reimburse any Credit Party or any Subsidiary of any Credit Party therefor except as expressly provided therein. In addition, Borrower agrees to pay or reimburse upon demand (i) Lender for all reasonable and documented out-of-pocket costs and expenses incurred by it or any of its directors, employees, attorneys, agents or sub-agents, in connection with the investigation, development, preparation, negotiation, syndication, execution, interpretation or administration of, any modification of any term of or termination of, any Loan Document, any commitment or proposal letter therefor, any other document prepared in connection therewith or the consummation and administration of any transaction contemplated therein, (ii) Lender for all reasonable and documented out-of-pocket costs and expenses incurred by it or any of its directors, employees, attorneys, agents or sub-agents in connection with internal audit reviews and Collateral, in accordance with Section 6.8 and (iii) Lender and its directors, employees, attorneys, agents and sub-agents, for all costs and expenses incurred in connection with (A) any refinancing or restructuring of the credit arrangements provided hereunder in the nature of a “work-out”, (B) the enforcement or preservation of any right or remedy under any Loan

Document, any Obligation, with respect to the Collateral or any other related right or remedy, or (C) the commencement, defense, conduct of, intervention in, or the taking of any other action with respect to, any proceeding (including any bankruptcy or insolvency proceeding) related to any Credit Party, any Subsidiary of any Credit Party, Loan Document or Obligation (or the response to and preparation for any subpoena or request for document production relating thereto), including Lender Expenses.

12.3Severability of Provisions. In case any provision in or obligation hereunder or under any other Loan Document shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

12.4Correction of Loan Documents. Lender may correct patent errors and fill in any blanks in the Loan Documents consistent with the agreement of the parties hereto so long as Lender provides Credit Parties with written notice of such correction and allows Credit Parties at least ten (10) days to object to such correction. In the event of such objection, such correction shall not be made except by an amendment signed by Lender and Credit Parties.

12.5Amendments in Writing; Integration.

(a)Except as expressly provided in Section 12.4, no amendment, restatement, supplement, modification, termination or waiver of any provision of this Agreement or any other Loan Document, no approval or consent thereunder, or any consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and Lender.

(b)This Agreement and the Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement and the Loan Documents merge into this Agreement and the Loan Documents.

12.6Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Agreement.

12.7Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms (including Section 3.4) and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been paid in full and satisfied. The obligation of Credit Parties in Section 12.2 to indemnify Lender shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

12.8Confidentiality. Any information regarding Credit Parties and their Subsidiaries and their businesses provided to Lender by or on behalf of any Credit Party pursuant to this Agreement shall be deemed “Confidential Information”; provided, however, that Confidential Information does not include information that is either: (a) in the public domain or in Lender’s or any of its Affiliates’ possession when disclosed to Lender or any of its Affiliates, or becomes part of the public domain after disclosure to Lender or any of its Affiliates other than as a result of a breach by Lender or any of its Affiliates of the obligations under this Section 12.8; or (b) disclosed to Lender or any of its Affiliates by a third Person if Lender or any of its Affiliates do not know that the third Person is prohibited from disclosing the information. Lender shall not disclose any Confidential Information to a third Person or use Confidential Information for any purpose other than the exercise of Lender’s rights and the performance of Lender’s obligations under the Loan Documents. The foregoing in this Section 12.8 notwithstanding, Lender may disclose Confidential Information: (i) to any of Lender’s Subsidiaries or Affiliates; (ii) to prospective transferees or purchasers of any interest in the Credit Extensions; (iii) as required by law, regulation, subpoena, or other order; (iv) to the extent requested by regulators having jurisdiction over Lender or as otherwise required in connection with Lender’s examination or audit; (v) as Lender considers appropriate in exercising remedies under the Loan Documents; and (vi) to third-Person service providers of Lender; provided, however, that the third Persons to which Confidential Information is disclosed pursuant to clauses (i), (ii) and (vi) are bound by obligations of confidentiality and non-use that are no less restrictive than those contained herein. Lender may use such confidential information for the development of databases, reporting purposes, and market analysis so long as such confidential information is aggregated and anonymized prior to distribution unless otherwise expressly permitted by Credit Parties.

The provisions of the immediately preceding paragraph shall survive the termination of this Agreement.

12.9Attorneys’ Fees, Costs and Expenses. In any action or proceeding between any Credit Party and Lender arising out of or relating to the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled.

12.10Right of Set-Off. In addition to any rights now or hereafter granted under Requirements of Law and not by way of limitation of any such rights, upon the occurrence of an Event of Default and at any time thereafter during the continuance of any Event of Default, Lender is hereby authorized by each Credit Party at any time or from time to time, without notice to any Credit Party or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts) and any other Indebtedness at any time held or owing by Lender to or for the credit or the account of any Credit Party against and on account of the obligations and liabilities of any Credit Party to Lender hereunder and under the other Loan Documents, including all claims of any nature or description arising out of or connected hereto or with any other Loan Document, irrespective of whether or not (a) Lender shall have made any demand hereunder or (b) the principal of or the interest on the Term Loan or any other amounts due hereunder shall have become due and payable pursuant to Section 2 and although such obligations and liabilities, or any of them, may be contingent or unmatured.

12.11Marshaling; Payments Set Aside. Lender shall not be under any obligation to marshal any assets in favor of any Credit Party or any other Person or against or in payment of any or all of the Obligations. To the extent that any Credit Party makes a payment or payments to Lender, or Lender enforces any Liens or exercises its rights of setoff, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, any other state or federal law, common law or any equitable cause, then, to the extent of such recovery and to the extent not expressly prohibited by Requirements of Law, the obligation or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment or payments had not been made or such enforcement or setoff had not occurred.

12.12Electronic Execution of Documents. The words “execution”, “signed”, “signature”, and words of like import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity and enforceability as a manually executed signature or the use of a paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any Requirements of Law, including any state law based on the Uniform Electronic Transactions Act.

12.13Captions. Section headings herein are included herein for convenience of reference only and shall not constitute a part hereof for any other purpose or be given any substantive effect.

12.14Construction of Agreement. The parties hereto mutually acknowledge that they and their attorneys have participated in the preparation and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties hereto caused the uncertainty to exist.

12.15Intercreditor Agreement Governs.

(a)The terms of this Agreement are subject to the Intercreditor Agreement. Lender (i) consents to the subordination of Liens provided for in the Intercreditor Agreement, (ii) agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreement and (iii) is authorized to enter into the Intercreditor Agreement as ABL Collateral Agent (as defined therein) and to be bound by the terms thereof. The foregoing provisions are intended as an inducement to Lender acting as a secured party under the Intercreditor Agreement to extend credit and Lender is an intended third party beneficiary of such provisions and the provisions of the Intercreditor Agreement. To the extent the provisions of this Agreement conflict or are inconsistent with the Intercreditor Agreement, Lender consents and agrees that the Intercreditor Agreement will control.

(b)Notwithstanding anything to the contrary herein, in any Noteholder Document or any ABL Document (each as defined in the Intercreditor Agreement), the Grantors shall not be required to act or refrain from acting (i) pursuant to any Noteholder Document solely with respect to any ABL First Lien Collateral (as defined in the Intercreditor Agreement) in any manner that would cause a default under any ABL Document, or (ii) pursuant to any ABL Document solely with respect to any Noteholder First Lien Collateral (as defined in the Intercreditor Agreement) in any manner that would cause a default under any Noteholder Document. For the avoidance of doubt and for the purposes of this Section 12.15(b) only, the terms “Noteholder Document” and “ABL Document” do not include the Intercreditor Agreement.

12.16Third Parties. Nothing in this Agreement, whether express or implied, is intended to: (a) confer any benefits, rights or remedies under or by reason of this Agreement on any Persons other than the express parties to it and their respective permitted successors and assigns; (b) relieve or discharge the obligation or liability of any Person not an express party to this Agreement; or (c) give any Person not an express party to this Agreement any right of subrogation or action against any party to this Agreement.

12.17No Fiduciary Duty. Lender may have economic interests that conflict with those of the Credit Parties. Each Credit Party agrees that nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between Lender, on the one hand, and such Credit Party, its Subsidiaries, and any of their respective stockholders or affiliates, on the other hand. Each Credit Party acknowledges and agrees that (a) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between Lender, on the one hand, and such Credit Party, its Subsidiaries and their respective affiliates, on the other, (b) in connection therewith and with the process leading to such transaction, Lender is acting solely as a principal and not the agent or fiduciary of such Credit Party, its Subsidiaries or their respective affiliates, management, stockholders, creditors or any other person, (c) Lender has not assumed an advisory or fiduciary responsibility in favor of any Credit Party, its Subsidiaries or their respective affiliates with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether Lender or any of its affiliates has advised or is currently advising such Credit Party, its Subsidiaries or their respective affiliates on other matters) or any other obligation to such Credit Party, its Subsidiaries or their respective affiliates except the obligations expressly set forth in the Loan Documents, and (d) each Credit Party, its Subsidiaries and their respective affiliates have consulted their own legal and financial advisors to the extent each deemed appropriate. Each Credit Party further acknowledges and agrees that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. Each Credit Party agrees that it will not claim that Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to such Credit Party, its Subsidiaries or their respective affiliates in connection with such transaction or the process leading thereto.

(b)It is acknowledged that, so long as Senior Secured Obligations secured by Senior Collateral shall be outstanding or any commitments to extend credit that would constitute Senior Secured Obligations secured by a Senior Lien shall be in effect, (i) all or a portion of the Senior Secured Obligations consists or may consist of Indebtedness that is revolving in nature, and the amount thereof that may be outstanding at any time or from time to time may be increased or repaid and subsequently reborrowed and (ii) the Senior Secured Obligations may, subject to the limitations set forth in the Indenture and the applicable ABL Agreement, be increased, extended, renewed, replaced, restated, supplemented, restructured, repaid, refunded, refinanced or otherwise amended or modified from time to time, all without affecting the subordination of the Junior Liens in respect of such Collateral or the provisions of this Agreement defining the relative rights of the applicable Senior Secured Parties and the applicable Junior Secured Parties. So long as Senior Secured Obligations secured by Senior Collateral shall be outstanding or any commitments to extend credit that would constitute Senior Secured Obligations secured by a Senior Lien shall be in effect, the lien priorities provided for herein shall not be altered or otherwise affected by any amendment, modification, supplement, extension, increase, replacement, renewal, restatement or refinancing of either the applicable Junior Secured Obligations or the applicable Senior Secured Obligations to the extent permitted by the Indenture, by the release of any such Collateral or of any guarantees securing any such Senior Secured Obligations or by any action that any Representative or Secured Party may take or fail to take in respect of any such Collateral or by the avoidance, invalidation or lapse of any Lien on any such Collateral.

SECTION 2.02 No Action With Respect to Junior Collateral Subject to Senior Liens. No Junior Representative or other Junior Secured Party shall commence or instruct any Junior Representative to commence any judicial or non-judicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator or similar official appointed for or over, attempt any action to take possession of, exercise any right, remedy or power with respect to, or otherwise take any action to enforce its interest in or realize upon, or take any other action available to it in respect of, any of its Junior Collateral under any Junior Security Document, applicable law or otherwise, at any time when such Junior Collateral shall be subject to any Senior Lien and any Senior Secured Obligations secured by such Senior Lien shall remain outstanding or any commitment to extend credit that would constitute Senior Secured Obligations secured by such Senior Lien shall remain in effect, it being agreed that only the Senior Representative with respect to such Collateral, acting in accordance with the applicable Senior Security Documents, shall be entitled to take any such actions or exercise any such remedies. Notwithstanding the foregoing, any Junior Representative may, subject to Section 2.05, take all such actions as it shall deem necessary to perfect or continue the perfection of its Junior Liens.

SECTION 2.03 No Duties of Senior Representative. (a) Each Junior Secured Party acknowledges and agrees that neither the applicable Senior Representative nor any other Senior Secured Party shall have any duties or other obligations to such Junior Secured Party with respect to any Senior Collateral, other than to transfer to the applicable Junior Representative (i) any proceeds of any such Collateral that constitutes Junior Collateral remaining in its possession following any sale, transfer or other disposition of such Collateral, the payment and satisfaction in full of the Senior Secured Obligations secured thereby and the termination of any commitment to extend credit that would constitute Senior Secured Obligations secured thereby (in each case, unless the Junior Liens on all such Junior Collateral are terminated and released prior to or

concurrently with such transaction), or, (ii) if such Senior Representative shall be in possession of all or any part of such Collateral after such payment and satisfaction in full and termination, such Collateral or any part thereof remaining, in each case without representation or warranty on the part of such Senior Representative or any Senior Secured Party. In furtherance of the foregoing, each Junior Secured Party acknowledges and agrees that until the Senior Secured Obligations secured by any Collateral in respect of which such Junior Secured Party holds a Junior Lien shall have been paid and satisfied in full and any commitment to extend credit that would constitute Senior Secured Obligations secured thereby shall have been terminated, the applicable Senior Representative shall be entitled, for the benefit of the holders of such Senior Secured Obligations, to sell, transfer or otherwise dispose of or deal with such Senior Collateral as provided herein and in compliance with the Senior Security Documents and applicable law without regard to any Junior Lien or any rights to which the holders of the applicable Junior Secured Obligations would otherwise be entitled as a result of such Junior Lien. Without limiting the foregoing, each Junior Secured Party agrees that neither the applicable Senior Representative nor any other Senior Secured Party shall have any duty or obligation first to marshal or realize upon any type of Senior Collateral (or any other collateral securing any Senior Secured Obligations on which the Senior Secured Party has a Senior Lien), or to sell, dispose of or otherwise liquidate all or any portion of such Collateral (or any other collateral securing any Senior Secured Obligations on which the Senior Secured Party has a Senior Lien), in any manner that would maximize the return to the applicable Junior Secured Parties, notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by such Junior Secured Parties from such realization, sale, disposition or liquidation.

(b)Each of the Junior Secured Parties waives any claim such Junior Secured Party may now or hereafter have against any Senior Representative or any other Senior Secured Party (or their representatives) arising out of (i) any actions which any Senior Representative or any Senior Secured Parties take or omit to take (including, actions with respect to the creation, perfection or continuation of Liens on any of its Senior Collateral, actions with respect to the foreclosure upon, sale, release or depreciation of, or failure to realize upon, any of such Collateral and actions with respect to the collection of any claim for all or any part of any Senior Secured Obligations from any account debtor, guarantor or any other party) in accordance with the applicable Senior Security Documents, any other agreement related thereto or applicable law or to the collection of any Senior Secured Obligations or the valuation, use, protection or release of any security for any Senior Secured Obligations, (ii) any election by any Senior Representative or any Senior Secured Parties, in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law) (iii) any borrowing by the Company or any of its subsidiaries, as debtor-in-possession, including any grant of a security interest, adequate protection, or administrative expense priority under Section 364 of the Bankruptcy Code to any party in connection with such borrowing, or (iv) any use of cash collateral by the Company or any of its subsidiaries, as debtor-in-possession, including any grant or award of adequate protection under Section 363 of the Bankruptcy Code to any party in connection with such use of cash collateral.

SECTION 2.04 No Interference; Payment Over; Reinstatement. (a) At any time when any Senior Secured Obligations secured by Senior Collateral shall be outstanding or any commitments to extend credit that would constitute Senior Secured Obligations secured by a Senior Lien shall be in effect, each respective Junior Secured Party agrees that (i) it will not take or cause to be taken any action the purpose or effect of which is, or could be, to make any respective Junior Lien pari passu with, or to give such Junior Secured Party any preference or priority relative to, any Senior Lien with respect to the Collateral subject to such Senior Lien and Junior Lien or any part thereof, (ii) it will not challenge or question in any proceeding the validity or enforceability of any such Senior Secured Obligations or Senior Security Document, or the validity, attachment, perfection or priority of any such Senior Lien, or the validity or enforceability of the priorities, rights or duties established by or other provisions of this Agreement, (iii) it will not take or cause to be taken any action the purpose or intent of which is, or could be, to contest, interfere, hinder or delay, in any manner, whether by judicial proceedings or otherwise, any sale, transfer or other disposition of the Collateral subject to such Junior Lien by any such Senior Secured Parties secured by Senior Liens on such Collateral or any Senior Representative acting on their behalf, (iv) it shall have no right to (A) direct any Senior Representative or any holder of Senior Secured Obligations to exercise any right, remedy or power with respect to the Collateral subject to such Junior Lien or (B) consent to the exercise by any Senior Representative or any other Senior Secured Party of any right, remedy or power with respect to the Collateral subject to such Junior Lien, (v) it will not institute any suit or assert in any suit, bankruptcy, insolvency or other proceeding any claim against any Senior Representative or other Senior Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to, and neither any Senior Representative nor any other Senior Secured Party shall be liable for, any action taken or omitted to be taken by such Senior Representative or other Senior Secured Party with respect to any Collateral securing such Senior Secured Obligations that is subject to such Junior Lien, (vi) it will not seek, and hereby waives any right, to have any Senior Collateral subject to such Junior Lien or any part thereof marshaled upon any foreclosure or other disposition of such Collateral and (vii) it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement.

(b)Each Junior Representative and each other Junior Secured Party hereby agrees that if it shall obtain possession of any respective Senior Collateral or shall realize any proceeds or payment in respect of any such Collateral, pursuant to any Junior Security Document or by the exercise of any rights available to it under applicable law or in any bankruptcy, insolvency or similar proceeding or through any other exercise of remedies, at any time when any Senior Secured Obligations secured or intended to be secured by such Collateral shall remain outstanding or any commitment to extend credit that would constitute Senior Secured Obligations secured or intended to be secured by such Senior Lien shall remain in effect, then it shall hold such Collateral, proceeds or payment in trust or as agent, as the case may be, for the applicable Senior Secured Parties and transfer such Collateral, proceeds or payment, as the case may be, to the applicable Senior Representative promptly after obtaining actual knowledge or notice from the applicable Senior Secured Parties that it has possession of such Senior Collateral or proceeds or payments in respect thereof. Each Junior Secured Party agrees that if, at any time, it receives notice or obtains actual knowledge that all or part of any payment with respect to any respective Senior Secured Obligations previously made shall be rescinded for any reason whatsoever, such Junior Secured Party shall promptly pay over to the applicable Senior

Representative any payment received and then held by it in respect of any Collateral subject to any Senior Lien securing such Senior Secured Obligations and shall promptly turn any Collateral subject to any such Senior Lien then held by it over to the applicable Senior Representative, and the provisions set forth in this Agreement shall be reinstated as if such payment had not been made, until the payment and satisfaction in full of such Senior Secured Obligations.

SECTION 2.05 Automatic Release of Junior Liens. (a) Each Junior Representative and each other Junior Secured Party agree that in the event of a sale, transfer or other disposition of any Senior Collateral subject to any Junior Lien in favor of such Junior Secured Representative or such Junior Secured Party (regardless of whether or not an Event of Default has occurred and is continuing under the applicable Junior Documents at the time of such sale, transfer or other disposition), such Junior Lien on such Collateral shall terminate and be released automatically and without further action if the applicable Senior Liens on such Collateral are released and if such sale, transfer or other disposition either (x) is then not prohibited by such Junior Documents or (y) occurs in connection with the foreclosure (including by a Senior Representative or other Senior Secured Party) upon or other exercise of rights and remedies with respect to such Senior Collateral, provided that such Junior Lien shall remain in place with respect to any proceeds of a sale, transfer or other disposition under this clause (a) that remain after the satisfaction in full of such Senior Secured Obligations.

(b)Each Junior Representative agrees to execute and deliver (at the sole cost and expense of the Grantors) all such releases and other instruments as shall reasonably be requested by any applicable Senior Representative to evidence and confirm any release of Junior Collateral provided for in this Section, and upon the Junior Representative’s failure to do so within the prescribed time frame set forth in New York UCC Section 9-513(b) or (c), as applicable, the appropriate Senior Representative is hereby granted a limited power of attorney to execute any necessary UCC-3 filing or similar document necessary to effect such a release.

SECTION 2.06 Certain Agreements With Respect to Bankruptcy or Insolvency Proceedings. (a) This Agreement shall continue in full force and effect notwithstanding the commencement of any proceeding under the Bankruptcy Code or any other Federal, state or foreign bankruptcy, insolvency, receivership or similar law by or against the Company or any of its subsidiaries.

(b)So long as any Senior Secured Obligations secured by Senior Collateral shall be outstanding or any commitments to extend credit that would constitute Senior Secured Obligations secured by a Senior Lien shall be in effect, if the Company or any of its subsidiaries shall become subject to a case under the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law) and shall, as debtor(s)-in-possession, move for approval of financing (“DIP Financing”) to be provided by one or more lenders (the “DIP Lenders”) under Section 364 of the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law) or the use of cash collateral with the consent of the DIP Lenders under Section 363 of the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law), each Junior Secured Party agrees that it will raise no objection to (and, upon the grant or award of adequate protection acceptable to the holders of Senior Secured Obligations with comparable adequate protection granted or awarded to the ABL Collateral Agent or the Noteholder Collateral Agent and Trustee, as

applicable, junior in priority only to that of the holders of Senior Secured Obligations, shall affirmatively consent to) any such financing to the extent secured by Liens on any respective Senior Collateral securing the same (“DIP Financing Liens”) or to any use of cash collateral that constitutes such Senior Collateral, unless the applicable Senior Secured Parties, or a representative authorized by such Senior Secured Parties, shall then oppose or object to such DIP Financing or such DIP Financing Liens or use of cash collateral (and, to the extent that such DIP Financing Liens are senior to, or rank pari passu with, the applicable Senior Liens, the applicable Junior Representative will, for itself and on behalf of the other applicable Junior Secured Parties, subordinate the Junior Liens on such Senior Collateral to such Senior Liens and the DIP Financing Liens), so long as each Secured Party retains Liens on all the applicable Collateral, including proceeds thereof arising after the commencement of such proceeding, with the same relative priority as existed prior to the commencement of the case under the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law).

(c)So long as any Senior Secured Obligations secured by Senior Collateral shall be outstanding or any commitments to extend credit that would constitute Senior Secured Obligations secured by a Senior Lien shall be in effect, each Junior Secured Party agrees that it will not object to or oppose a sale or other disposition of any Senior Collateral (or any portion thereof) under Section 363 of the Bankruptcy Code or any other provision of the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law) if the applicable Senior Secured Parties shall have consented to such sale or disposition of such Senior Collateral.

SECTION 2.07 Reinstatement. In the event that any of the Senior Secured Obligations shall be paid in full and such payment or any part thereof shall subsequently, for whatever reason (including an order or judgment for disgorgement of a preference under Title 11 of the Bankruptcy Code (or under any other applicable foreign bankruptcy, insolvency, receivership or similar law) or the settlement of any claim in respect thereof), be required to be returned or repaid, the terms and conditions of this Article II shall be fully applicable thereto until all such Senior Secured Obligations shall again have been paid in full in cash.

SECTION 2.08 Entry Upon Premises by the ABL Collateral Agent and the ABL Lenders. (a) So long as any Senior Secured Obligations secured by Senior Collateral shall be outstanding or any commitments to extend credit that would constitute Senior Secured Obligations secured by a Senior Lien shall be in effect, if any ABL Collateral Agent takes any enforcement action with respect to any ABL First Lien Collateral on which it holds ABL Liens, the Noteholder Secured Parties (i) shall cooperate with such ABL Collateral Agent (at the sole cost and expense of such ABL Collateral Agent and subject to the condition that the Noteholder Secured Parties shall have no obligation or duty to take any action or refrain from taking any action that could reasonably be expected to result in the incurrence of any liability or damage to the Noteholder Secured Parties) in its efforts to enforce its security interest in such ABL First Lien Collateral and to finish any work-in-process and assemble such ABL First Lien Collateral, (ii) shall not hinder or restrict in any respect such ABL Collateral Agent from enforcing its security interest in such ABL First Lien Collateral or from finishing any work-in-process or assembling such ABL First Lien Collateral, and (iii) shall permit such ABL Collateral Agent, its employees, agents, advisers and representatives, at the sole cost and expense of the applicable ABL Secured Parties and upon reasonable advance notice, to enter upon and use the Noteholder

First Lien Collateral (including (x) equipment, processors, computers and other machinery related to the storage or processing of records, documents or files and (y) intellectual property), for a period not to exceed 90 days after the taking of such enforcement action, for purposes of (A) assembling and storing such ABL First Lien Collateral and completing the processing of and turning into finished goods of such ABL First Lien Collateral consisting of work-in-process, (B) selling any or all of the applicable ABL First Lien Collateral located on or in such Noteholder First Lien Collateral, whether in bulk, in lots or to customers in the ordinary course of business or otherwise, (C) removing any or all of the applicable ABL First Lien Collateral located on such Noteholder First Lien Collateral, or (D) taking reasonable actions to protect, secure, and otherwise enforce the rights of the applicable ABL Secured Parties in and to any applicable ABL First Lien Collateral, provided, however, that nothing contained in this Agreement shall restrict the rights of the Trustee or the Noteholder Collateral Agent from selling, assigning or otherwise transferring any Noteholder First Lien Collateral prior to the expiration of such 90-day period if the purchaser, assignee or transferee thereof agrees to be bound by the provisions of this Section. If any stay or other order prohibiting the exercise of remedies with respect to the applicable ABL First Lien Collateral has been entered by a court of competent jurisdiction, such 90-day period shall be tolled during the pendency of any such stay or other order.

(b)In no event shall such ABL Secured Parties have any liability to the Noteholder Secured Parties pursuant to this Section as a result of any condition on or with respect to the Noteholder First Lien Collateral existing prior to the date of the exercise by such ABL Secured Parties of their rights under this Section and such ABL Secured Parties shall have no duty or liability to maintain the Noteholder First Lien Collateral in a condition or manner better than that in which it was maintained prior to the use thereof by such ABL Secured Parties, or for any diminution in the value of the Noteholder First Lien Collateral that results solely from ordinary wear and tear resulting from the use of the Noteholder First Lien Collateral by such ABL Secured Parties in the manner and for the time periods specified under this Section 2.08. Without limiting the rights granted in this paragraph, such ABL Secured Parties shall cooperate with the Noteholder Secured Parties in connection with any efforts made by the Noteholder Secured Parties to sell the Noteholder First Lien Collateral to the extent such ABL Secured Parties obtain any interest in the Noteholder First Lien Collateral, subject to the condition that no ABL Secured Party shall have any obligation or duty to take any action or refrain from taking any action that could reasonably be expected to result in its incurrence of any liability or damage.

SECTION 2.09 Insurance. Unless and until any ABL Collateral Agent has sent written notice to the Trustee that the applicable ABL Obligations have been paid in full and all commitments to extend credit under the applicable ABL Agreement shall have been terminated, as between such ABL Collateral Agent, on the one hand, and the Trustee and the Noteholder Collateral Agent, as the case may be, on the other hand, only such ABL Collateral Agent will have the right (subject to the rights of the Grantors under the applicable ABL Documents and the Noteholder Documents) to adjust or settle any insurance policy or claim covering or constituting any of the applicable ABL First Lien Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding solely affecting such ABL First Lien Collateral. Unless and until the Trustee has sent written notice to any ABL Collateral Agent that the Noteholder Obligations have been paid in full, as between such ABL Collateral Agent, on the one hand, and the Trustee and the Noteholder Collateral Agent, as the case may be, on the other hand, only the Noteholder Collateral Agent will have the right (subject to the rights

of the Grantors under the applicable ABL Documents and the Noteholder Documents) to adjust or settle any insurance policy covering or constituting any applicable Noteholder First Lien Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding solely affecting any applicable Noteholder First Lien Collateral. To the extent that an insured loss covers or constitutes both ABL First Lien Collateral and Noteholder First Lien Collateral, then the applicable ABL Collateral Agent and the Noteholder Collateral Agent will work jointly and in good faith to collect, adjust or settle (subject to the rights of the Grantors under the applicable ABL Documents and the Noteholder Documents) under the relevant insurance policy.

SECTION 2.10 Refinancings. Any ABL Obligations and the Noteholder Obligations may be refinanced or replaced (either immediately or after the passage of time), in whole or in part, in each case, without notice to, or the consent (except to the extent a consent is otherwise required to permit the refinancing transaction under any ABL Document or any Noteholder Document) of any ABL Secured Party or any Noteholder Secured Party, all without affecting the Lien priorities provided for herein or the other provisions hereof, provided, however, that the holders of any such refinancing or replacement indebtedness (or an authorized agent or trustee on their behalf) bind themselves in writing to the terms of this Agreement pursuant to such documents or agreements (including amendments or supplements to this Agreement) as any applicable ABL Collateral Agent or the Noteholder Collateral Agent, as the case may be, shall reasonably request and in form and substance reasonably acceptable to each such ABL Collateral Agent or the Noteholder Collateral Agent, as the case may be. In connection with any refinancing or replacement contemplated by this Section 2.10, this Agreement shall be amended at the request and sole expense of the Company, and without the consent of any Representative, (a) to add parties (or any authorized agent or trustee therefor) providing any such refinancing or replacement indebtedness, (b) to establish that Liens on any Noteholder First Lien Collateral securing such refinancing or replacement indebtedness shall have the same priority as the Liens on any Noteholder First Lien Collateral securing the indebtedness being refinanced or replaced and (c) to establish that the Liens on any ABL First Lien Collateral securing such refinancing or replacement indebtedness shall have the same priority as the Liens on any ABL First Lien Collateral securing the indebtedness being refinanced or replaced, all on the terms provided for herein immediately prior to such refinancing or replacement.

SECTION 2.11 Amendments to Security Documents. (a) Without the prior written consent of any applicable Senior Representative, no Junior Security Document may be amended, supplemented or otherwise modified or entered into to the extent such amendment, supplement or modification, or the terms of any new Junior Security Document, would be prohibited by, or would require any Grantor to act or refrain from acting in a manner that would violate, any of the terms of this Agreement.

(b)In the event that any Senior Representative enters into any amendment, waiver or consent in respect of any of the Senior Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any such Senior Security Document that relate directly to any Senior Collateral on which a Junior Lien exists or changing in any manner the rights of such Senior Representative, the applicable Senior Secured Parties, the Company or any other Grantor thereunder (including the release of any Liens on any applicable Senior Collateral permitted by Section 2.05), then such amendment,

waiver or consent shall apply automatically to any comparable provision of the comparable Junior Security Document with respect to such Junior Lien without the consent of the applicable Junior Representative or any applicable Junior Secured Party and without any action by such Junior Representative, the Company or any other Grantor; provided, however, that written notice of such amendment, waiver or consent shall have been given by the Company to such Junior Representative no later than two (2) Business Days following its effectiveness; and provided further, that no such amendment, waiver or consent shall be effective to (i) release any Junior Liens (other than as permitted by Section 2.05), (ii) permit any Liens on the Collateral except Liens permitted under the Junior Documents or this Agreement, or (iii) impose duties on the Junior Representative without its consent. Reasonably promptly following such effectiveness, the Company shall prepare and deliver, or cause to be prepared and delivered to the applicable Junior Representative, forms of amendment documents to any applicable Junior Security Documents to evidence the amendments to such Junior Security Documents previously effected pursuant to this Section 2.11(b).

SECTION 2.12 Legends. Each ABL Collateral Agent acknowledges with respect to the applicable ABL Documents, and the Trustee and the Noteholder Collateral Agent acknowledge with respect to the Noteholder Documents, that each such agreement will contain the appropriate legend set forth on Annex I in substantially the same terms as set forth therein.

SECTION 2.13 Permitted Liens. Notwithstanding anything herein to the contrary, neither this Agreement nor any term or provision hereof shall be construed to permit any ABL Secured Party to obtain, receive or be the beneficiary of any Lien on all or any portion of any Collateral (other than the ABL Collateral, to the extent permitted under the terms of the Indenture), irrespective of the time, order or method of creation, attachment or perfection of such Lien, including any Lien arising by operation of law or in connection with any judgment.

ARTICLE III

Gratuitous Bailment for Perfection of Certain Security Interests;
Rights Under Permits and Licenses

SECTION 3.01 General. Each Senior Representative agrees that if it shall at any time hold a Senior Lien on any Junior Collateral that can be perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of such Senior Representative, such Senior Representative will serve as gratuitous bailee for the applicable Junior Representative for the sole purpose of perfecting the Junior Lien of such Junior Representative on such Collateral. It is agreed that the obligations of such Senior Representative and the rights of such Junior Representative and the other applicable Junior Secured Parties in connection with any such bailment arrangement will be in all respects subject to the provisions of Article II. Notwithstanding anything to the contrary herein, such Senior Representative will be deemed to make no representation as to the adequacy of the steps taken by it to perfect the Junior Lien on any such Collateral and shall have no responsibility, duty, obligation or liability to such Junior Representative or any other applicable Junior Secured Party or any other person for such perfection or failure to perfect, it being understood that the sole purpose of this Article is to enable the applicable Junior Secured Parties to obtain a perfected Junior Lien on such Collateral

to the extent, if any, that such perfection results from the possession or control of such Collateral or any such account by such Senior Representative. Subject to Section 2.07, at such time as such Senior Secured Obligations secured by the applicable Senior Lien of such Senior Representative shall have been paid and satisfied in full and any commitment to extend credit that would constitute such Senior Secured Obligations shall have been terminated, such Senior Representative shall take all such actions in its power as shall reasonably be requested by such Junior Representative (at the sole cost and expense of the Grantors) to transfer possession or control of such Collateral or any such account (in each case to the extent such Junior Representative has a Lien on such Collateral or account after giving effect to any prior or concurrent releases of Liens) to such Junior Representative.

SECTION 3.02 Collection Accounts. The Company and its subsidiaries, to the extent required by an applicable ABL Document, shall maintain collection accounts relating to applicable ABL First Lien Collateral (the “Collection Accounts”, which term shall include any Lockbox Account relating to such ABL Document) in which collections from any Inventory and Accounts are deposited. The applicable ABL Collateral Agent will act as gratuitous bailee for the Trustee and the Noteholder Collateral Agent for the purpose of perfecting the Liens of the Noteholder Secured Parties in all such Collection Accounts and the cash and other assets therein as provided in Section 3.01 (but will have no duty, responsibility or obligation to the Noteholder Secured Parties except as set forth in the last sentence of this Section). Unless the Junior Liens on such ABL First Lien Collateral shall have been or concurrently are released, after the occurrence of the applicable ABL First Lien Collateral Transition Date, such ABL Collateral Agent shall at the request of the Noteholder Collateral Agent, cooperate with the Noteholder Collateral Agent (at the expense of the Grantors) in permitting “control” (as defined in Article 8 or Article 9 of the New York UCC) of any Collection Account to be transferred to the Noteholder Collateral Agent (or for other arrangements with respect to each such Collection Account satisfactory to the Noteholder Collateral Agent to be made) to the extent required by the Noteholder Security Documents.

SECTION 3.03 Rights under Permits and Licenses. The Trustee and the Noteholder Collateral Agent agree that if any ABL Collateral Agent shall require rights available under any permit or license controlled by the Trustee or the Noteholder Collateral Agent in order to realize on any applicable ABL First Lien Collateral, the Trustee or the Noteholder Collateral Agent, as the case may be, shall take all such actions as shall be available to it (at the sole expense of the Grantors), consistent with applicable law and reasonably requested by such ABL Collateral Agent, to make such rights available to such ABL Collateral Agent, subject to the Noteholder Liens. Each ABL Collateral Agent agrees that if the Trustee or the Noteholder Collateral Agent shall require rights available under any permit or license controlled by such ABL Collateral Agent in order to realize on any Noteholder First Lien Collateral, such ABL Collateral Agent shall take all such actions as shall be available to it (at the sole expense of the Grantors), consistent with applicable law and reasonably requested by the Trustee or the Noteholder Collateral Agent, as the case may be, to make such rights available to the Trustee or the Noteholder Collateral Agent, as the case may be, subject to the applicable ABL Liens.

ARTICLE IV

Whenever a Representative shall be required, in connection with the exercise of its rights or the performance of its obligations hereunder, to determine the existence or amount of any Senior Secured Obligations (or the existence of any commitment to extent credit that would constitute Senior Secured Obligations) or Junior Secured Obligations (or the existence of any commitment to extent credit that would constitute Junior Secured Obligations), or the existence of any Lien securing any such obligations, or the Collateral subject to any such Lien, it may request that such information be furnished to it in writing by the other applicable Representative and shall be entitled to make such determination on the basis of the information so furnished provided, however, that if a Representative shall fail or refuse reasonably promptly to provide the requested information, the requesting Representative shall be entitled to make any such determination by such method as it may, in the exercise its good faith judgment, determine, including by reliance upon a certificate of the Company. Each Representative may rely conclusively, and shall be fully protected in so relying, on any determination made by it in accordance with the provisions of the preceding sentence (or as otherwise directed by a court of competent jurisdiction) and shall have no liability to the Company or any of its subsidiaries, any Secured Party or any other person as a result of such determination.

ARTICLE V

Consent of Grantors

SECTION 5.01 Each Grantor hereby consents to the provisions of this Agreement and the intercreditor arrangements provided for herein and agrees that the obligations of the Grantors under the ABL Documents and the Noteholder Documents will in no way be diminished or otherwise affected by such provisions or arrangements (except as expressly provided herein).

Such payment or distribution will not reduce the Junior Secured Obligations.
