LOAN AND SECURITY AGREEMENT

THIS LOAN AND SECURITY AGREEMENT (this “Agreement”), dated as of June 2, 2011 (the “Effective Date”) by and among HORIZON PHARMA USA, INC., a Delaware corporation (formerly called HORIZON THERAPEUTICS, INC.) (“Horizon”), HORIZON PHARMA, INC., a Delaware corporation (“Horizon Pharma,”), HORIZON PHARMA (UK) LIMITED, a company registered under the laws of England and Wales with registration number 5819120, with its registered offices in the United Kingdom at x/x Xxxxxx & Xxxxxx (XX) XXX, Xxxxx 42, 00 Xxx Xxxxx Xxxxxx, Xxxxxx XX0X 0XX (“Horizon UK”, and together with Horizon and Horizon Pharma, each a “Borrower” and, collectively, jointly and severally, the “Borrowers”), the Lenders listed on the signature pages hereto or otherwise party hereto from time to time, and OXFORD FINANCE LLC, a Delaware limited liability company with an office located at 000 Xxxxx Xxxxxxx Xxxxxx, Xxxxxxxxxx, Xxxxxxxx 00000 (“Oxford”), as administrative agent for the Lenders, or any successor administrative agent (in such capacity, the “Administrative Agent”), provides the terms on which the Lenders shall make, and Borrowers shall repay, the Credit Extensions (as hereinafter defined). The parties agree as follows:

1. ACCOUNTING AND OTHER TERMS

Except as otherwise expressly provided herein, all accounting terms not otherwise defined in this Agreement shall have the meanings assigned to them in conformity with Applicable Accounting Standards. Calculations and determinations must be made following Applicable Accounting Standards. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 15. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein. All references to “Dollars” or “$” are United States Dollars, unless otherwise noted.

2. LOANS AND TERMS OF PAYMENT

2.1. Promise to Pay.

Borrowers hereby unconditionally promise to pay each Lender, the outstanding principal amount of all Term Loans advanced to Borrowers by such Lender and accrued and unpaid interest thereon and any other amounts due hereunder as and when due in accordance with this Agreement.

2.2. Term Loans.

(a) Availability. Subject to the terms and conditions of this Agreement, the Lenders agree, severally and not jointly, to make term loans to Borrowers during the Draw Period in the aggregate amount of Seventeen Million Dollars ($17,000,000), to be allocated as between the Borrowers as the Borrowers shall determine, according to each Lender’s Term Commitment as set forth on Schedule 1.1 hereto (such term loans are hereinafter referred to singly as a “Term Loan”, and collectively as the “Term Loans”). All Term Loans shall be made on the same Funding Date. After repayment, no Term Loan may be re-borrowed.

(b) Repayment. Borrowers shall make monthly payments of interest only commencing on the first (1^st) Payment Date following the Funding Date of the Term Loans, and continuing on the Payment Date of each successive month thereafter through and including the Payment Date immediately preceding the Amortization Date. Commencing on the Amortization Date, and continuing on the Payment Date of each month thereafter, Borrowers shall make consecutive equal monthly payments of principal and interest, in arrears, to each Lender, as calculated by Administrative Agent (which calculations shall be deemed correct absent manifest error) based upon: (1) the amount of such Lender’s Term Loan, (2) the effective rate of interest, as determined in Section 2.3(a), and (3) a repayment schedule equal to thirty-six (36) months. All unpaid principal and accrued and unpaid interest with respect to the Term Loans is due and payable in full on the Term Loan Maturity Date. The Term Loans may only be prepaid in accordance with Sections 2.2(c) and 2.2(d).

(c) Mandatory Prepayments. If the Term Loans are accelerated following the occurrence and during the continuance of an Event of Default, Borrowers shall immediately pay to Lenders, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of: (i) all outstanding principal of the Term Loans plus accrued interest thereon through the prepayment date, (ii) the Final Payment, (iii) the Prepayment Fee, plus (iv) all other sums, that shall have become due and payable, including Lender Expenses and

interest at the Default Rate with respect to any past due amounts. Notwithstanding (but without duplication with) the foregoing, on the Term Loan Maturity Date, if the Final Payment had not previously been paid in full in connection with the prepayment of the Term Loans in full, Borrowers shall pay to Administrative Agent, for payment to each Lender in accordance with its respective Pro Rata Share, the Final Payment in respect of the Term Loan(s).

(d) Permitted Prepayment of Term Loans. Borrowers shall have the option to prepay all, but not less than all, of the Term Loans advanced by the Lenders under this Agreement, provided Borrowers (i) provide written notice to Administrative Agent of its election to prepay the Term Loans at least ten (10) days prior to such prepayment, and (ii) pay to the Lenders on the date of such prepayment, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of (A) all outstanding principal of the Term Loans plus accrued interest thereon through the prepayment date, (B) the Final Payment, (C) the Prepayment Fee, plus (D) all other sums, that shall have become due and payable, including Lender Expenses, if any, and interest at the Default Rate with respect to any past due amounts.

2.3. Payment of Interest on the Credit Extensions.

(a) Interest Rate. Subject to Section 2.3(b), the principal amount outstanding under the Term Loans shall accrue interest at a fixed per annum rate (which rate shall be fixed for the duration of the Term Loans) equal to the Basic Rate, determined by Administrative Agent on the Funding Date of the Term Loans, which interest shall be payable monthly in accordance with Sections 2.2(b) and 2.3(e). Interest shall accrue on each Term Loan commencing on, and including, the day on which the Term Loan is made, and shall accrue on a Term Loan, or any portion thereof, for the day on which the Term Loan or such portion is paid.

(b) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum which is five percentage points (5.00%) above the rate that is otherwise applicable thereto (the “Default Rate”). Payment 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 Administrative Agent.

(c) 360-Day Year. Interest shall be computed on the basis of a 360-day year consisting of twelve (12) months of thirty (30) days.

(d) Debit of Accounts. Administrative Agent and each Lender may debit any of Borrower’s deposit accounts, including the Designated Deposit Account, for principal and interest payments or any other amounts Borrowers owe the Lenders under the Loan Documents when due. Each Lender will notify Borrowers promptly after debiting Borrowers’ accounts. These debits shall not constitute a set-off.

(e) Payments. Except as otherwise expressly provided herein, all loan payments by Borrowers hereunder shall be made to the respective Lender to which such payments are owed, at such Lender’s office in immediately available funds on the date specified herein. Unless otherwise provided, interest is payable monthly on the Payment Date of each month. Payments of principal and/or interest received after 2:00 p.m. Eastern time 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 Borrowers 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.

2.4. Fees. Borrowers shall pay to Administrative Agent:

(a) Facility Fee. A fully earned, non-refundable facility fee of One Hundred Seventy Thousand Dollars ($170,000) to be shared between the Lenders pursuant to their respective Commitment Percentages as shown on Schedule 1.1, of which One Hundred Thirty Five Thousand Dollars ($135,000) was received by the Lenders prior to the Effective Date. The remaining Thirty Five Thousand Dollars ($35,000) of the facility fee shall be due and payable on the Effective Date;

- 2 -

(b) Final Payment. The Final Payment, when due hereunder, to be shared between the Lenders in accordance with their respective Pro Rata Shares;

(c) Prepayment Fee. The Prepayment Fee, when due hereunder, to be shared between the Lenders in accordance with their respective Pro Rata Shares; and

(d) Lender Expenses. All Lender Expenses (including reasonable attorneys’ fees and expenses for documentation and negotiation of this Agreement) incurred through and after the Effective Date, when due.

2.5. Requirements of Law; Increased Costs. In the event that any applicable law, order, regulation, treaty or directive issued or amended after the Effective Date by any applicable central bank or other Governmental Authority, or any change after the Effective Date in the governmental or judicial interpretation or application thereof, or compliance by any Lender with any request or directive (whether or not having the force of law) issued subsequent to the date hereof by any central bank or other Governmental Authority:

(a) Does or shall subject any Lender to any Tax of any kind whatsoever with respect to this Agreement or any Term Loans made hereunder, or change the basis of taxation of payments to such Lender of principal, fee, interest or any other amount payable hereunder (except, in each case, for a change in the Tax on the overall net income of, or franchise Taxes payable by, such Lender);

(b) Does or shall impose, modify or hold applicable any reserve, capital requirement, special deposit, compulsory loan or similar requirements against assets held by, or deposits or other liabilities in or for the account of, advances or loans by, or other credit extended by, or any other acquisition of funds by, any applicable lending office of any Lender making Term Loans hereunder; or

(c) Does or shall impose on such Lender any other condition; and the result of any of the foregoing is to increase the cost to such Lender (as determined by such Lender in good faith using calculation methods customary in the industry) of making, renewing or maintaining any Term Loan or to reduce any amount receivable in respect thereof or to reduce the rate of return on the capital of such Lender or any Person controlling such Lender, then, in any such case, Borrowers shall promptly pay to the Administrative Agent for remittance to such Lender, upon its receipt of the certificate described below, any additional amounts necessary to compensate such Lender for such additional cost or reduced amounts receivable or rate of return as reasonably determined by such Lender with respect to this Agreement or the Term Loans made hereunder. If a Lender becomes entitled to claim any additional amounts pursuant to this Section 2.5, it shall promptly notify Borrowers through the Administrative Agent of the event by reason of which it has become so entitled, and a certificate as to any additional amounts payable pursuant to the foregoing sentence containing the calculation thereof in reasonable detail submitted by a Lender, through the Administrative Agent, to Borrowers shall be conclusive in the absence of manifest error. The provisions hereof shall survive the termination of this Agreement and payment of the outstanding Term Loans and all other Obligations.

(d) Failure or delay on the part of any Lender to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of such Lender’s right to demand such compensation; provided that Borrowers shall not be under any obligation to compensate any Lender under this Section 2.5 with respect to increased costs or reductions with respect to any period prior to the date that is 180 days prior to the date of the delivery of the statement required pursuant to the foregoing paragraph; provided further that the foregoing limitation shall not apply to any increased costs or reductions arising out of the retroactive application of any change in any law, treaty, governmental rule, regulation or order within such 180-day period.

2.6. Taxes; Withholding, etc.

(a) All sums payable by any Credit Party hereunder and under the other Loan Documents shall (except to the extent required by law) be paid free and clear of, and without any deduction or withholding on account of, any Tax (other than a Tax on the overall net income of any Lender) 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, the United Kingdom, or any other jurisdiction from or to which a payment is made by or on behalf of any

- 3 -

Credit Party or by any federation or organization of which the United States of America, the United Kingdom, or any such jurisdiction is a member at the time of payment. In addition, Borrowers agree to pay, and shall indemnify and hold each Lender harmless from, any present or future stamp or documentary Taxes or any other sales, transfer, excise, mortgage recording or property Taxes, charges or similar levies that arise from any payment made hereunder or under the Term Loans or from the execution, issuance, delivery or registration of, any of the Loan Documents, and within thirty days after the date of paying such sum, the Borrowers shall furnish to the Lender the original or a certified copy of a receipt evidencing payment thereof. If a Lender or the Administrative Agent shall become aware that it is entitled to receive a refund in respect of amounts paid by any Credit Party pursuant to this Section 2.6, which refund in the good faith judgment of such Lender or the Administrative Agent is allocable to such payment, it shall promptly notify such Credit Party of the availability of such refund and shall, within 30 days after the receipt of a request by such Credit Party, apply for such refund. If any Lender or the Administrative Agent receives a refund in respect of any amounts paid by any Credit Party pursuant to this Section 2.6 or any Lender receives a credit against the Tax on the overall net income of the Lender, which refund or credit in the good faith judgment of such Lender or the Administrative Agent is allocable to such payment, it shall promptly notify such Credit Party of such refund or credit and shall, within 30 days after receipt, repay such refund or credit to such Credit Party net of all out-of-pocket expenses of such Lender or the Administrative Agent; provided, however, that such Credit Party, upon the request of such Lender or the Administrative Agent, agrees to repay the amount paid over to such Credit Party to such Lender or the Administrative Agent in the event such Lender or the Administrative Agent is required to repay such refund or credit.

(b) If any Credit Party or any other Person is required by law to make any deduction or withholding on account of any such Tax from any sum paid or payable by any Credit Party to the Administrative Agent or any Lender under any of the Loan Documents: (i) Borrowers shall notify the Administrative Agent of any such requirement or any change in any such requirement as soon as any Borrower becomes aware of it; (ii) Borrowers 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 the Administrative Agent or such Lender, as the case may be) on behalf of and in the name of the Administrative Agent or such Lender; (iii) the sum payable by such Credit Party in respect of which the relevant deduction, withholding or payment is required shall be increased to the extent necessary to ensure that, after the making of that deduction, withholding or payment (including any deductions applicable to additional sums payable under this Section 2.6(b), the Administrative Agent or such Lender, as the case may be, receives on the due date a net sum equal to what it would have received had no such deduction, withholding or payment been required or made; and (iv) within thirty days after paying any sum from which it is required by law to make any deduction or withholding, and within thirty days after the due date of payment of any Tax which it is required by clause (ii) above to pay, Borrowers shall deliver to the Administrative Agent evidence satisfactory to the other affected parties of such deduction, withholding or payment and of the remittance thereof to the relevant taxing or other Governmental Authority; provided, no such additional amount shall be required to be paid to any Lender under clause (iii) above except to the extent that any change after the date hereof in any such requirement for a deduction, withholding or payment as is mentioned therein shall result in an increase in the rate of such deduction, withholding or payment from that in effect at the date hereof, in respect of payments to such Lender. In the event that all or any portion of this Agreement is assigned by a Lender, no such additional amount shall be required to be paid to any assignee under clause (iii) above except to the extent that, after the date of the Assignment Agreement, any change in any such requirement for a deduction, withholding or payment shall result in an increase in the rate of such deduction, withholding or payment from that in effect on the date of the Assignment Agreement. The Borrowers shall indemnify for the full amount of any deduction, withholding, or payment made pursuant to this Section 2.6(b) (including without limitation any Taxes imposed by any jurisdiction on amounts payable under this Section 2.6(b) paid by each Lender and any liability (including penalties, interest and expense) arising therefrom or with respect thereto. Any indemnification payment pursuant to this Section 2.6 shall be made within thirty days from written demand therefor.

(c) Each Lender that is not a United States Person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) for U.S. federal income Tax purposes (a “Non U.S. Lender”) shall deliver to the Administrative Agent for transmission to Borrowers, on or prior to the Effective Date, and at such other times as may be necessary in the determination of Borrowers or the Administrative Agent (each in the reasonable exercise of its discretion), two original copies of Internal Revenue Service Form W 8BEN or W 8ECI (or any successor forms), properly completed and duly executed by such Lender, and such other documentation required under the Internal Revenue Code and reasonably requested by Borrowers to establish that such Lender is not subject to deduction or withholding of United States federal income Tax with respect to any payments to such Lender of

- 4 -

principal, interest, fees or other amounts payable under any of the Loan Documents. Each Lender that is a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) for United States federal income Tax purposes (a “U.S. Lender”) shall deliver to the Administrative Agent and Borrowers on or prior to the Effective Date two original copies of Internal Revenue Service Form W-9 (or any successor form), properly completed and duly executed by such Lender, certifying that such U.S. Lender is entitled to an exemption from United States backup withholding, or otherwise prove that it is entitled to such an exemption. Each Lender required to deliver any forms, certificates or other evidence with respect to United States federal income Tax or backup withholding matters pursuant to this Section 2.6(c) hereby agrees, from time to time after the initial delivery by such Lender of such forms, certificates or other evidence, whenever a lapse in time or change in circumstances renders such forms, certificates or other evidence obsolete or inaccurate in any material respect, that such Lender shall promptly deliver to the Administrative Agent for transmission to Borrowers two new original copies of Internal Revenue Service Form W-8BEN or W-8ECI or W-9 (or any successor form), as the case may be, properly completed and duly executed by such Lender, and such other documentation required under the Internal Revenue Code and reasonably requested by Borrowers to confirm or establish that such Lender is not subject to deduction, backup withholding or withholding of United States federal income Tax with respect to payments to such Lender under the Loan Documents, or notify the Administrative Agent and Borrowers of its inability to deliver any such forms, certificates or other evidence. Borrowers shall not be required to pay any additional amount to any Non U.S. Lender under Section 2.6(b)(iii) if such Lender shall have failed (1) to deliver the forms, certificates or other evidence referred to in this Section 2.6(c), or (2) to notify the Administrative Agent and Borrowers of its inability to deliver any such forms, certificates or other evidence, as the case may be; provided, if such Lender shall have satisfied the requirements of the first sentence of this Section 2.6(c) on the Effective Date, nothing in this last sentence of this Section 2.6(c) shall relieve Borrowers of their obligations to pay any additional amounts pursuant to this Section 2.6 in the event that, as a result of any change in any applicable law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof, such Lender is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing the fact that such Lender is not subject to withholding as described herein.

2.7. Defaulting Lenders. Anything contained herein to the contrary notwithstanding, in the event that any Lender, other than at the direction or request of any regulatory agency or authority, defaults (a “Defaulting Lender”) in its obligation to fund (a “Funding Default”) any Term Loan (in each case, a “Defaulted Loan”), then (a) during any Default Period with respect to such Defaulting Lender, such Defaulting Lender shall be deemed not to be a “Lender” for purposes of voting on any matters (including the granting of any consents or waivers) with respect to any of the Loan Documents; and (b) to the extent permitted by applicable law, until such time as the Defaulting Lender shall have cured such Funding Default, (i) any voluntary prepayment of the Term Loans shall, if such paying Borrower so directs at the time of making such voluntary prepayment, be applied to the Term Loans of other Lenders as if such Defaulting Lender had no Term Loans outstanding, and (ii) any mandatory prepayment of the Term Loans shall, if such paying Borrower so directs at the time of making such mandatory prepayment, be applied to the Term Loans of other Lenders (but not to the Term Loans of such Defaulting Lender) as if such Defaulting Lender had funded all Defaulted Loans of such Defaulting Lender, it being understood and agreed that such paying Borrower shall be entitled to retain any portion of any mandatory prepayment of the Term Loans that is not paid to such Defaulting Lender solely as a result of the operation of the provisions of this clause (b). No Term Commitment of any Lender shall be increased or otherwise affected, and, except as otherwise expressly provided in this Section 2.7, performance by Borrowers of their obligations hereunder and the other Loan Documents shall not be excused or otherwise modified as a result of any Funding Default or the operation of this Section 2.7. The rights and remedies against a Defaulting Lender under this Section 2.7 are in addition to other rights and remedies which Borrowers may have against such Defaulting Lender with respect to any Funding Default and which the Administrative Agent or any Lender may have against such Defaulting Lender with respect to any Funding Default.

2.8. Evidence of Debt; Register; Lenders’ Books and Records; Term Loan Notes.

(a) Lenders’ Evidence of Debt. Each Lender shall maintain on its internal records an account or accounts evidencing the Obligations of each Borrower to such Lender, including the amounts of the Term Loans made by it and each repayment and prepayment in respect thereof. Any such recordation shall be conclusive and binding on Borrowers, absent manifest error; provided, that the failure to make any such recordation, or any error in such recordation, shall not affect any Lender’s Term Commitments or Borrowers’ Obligations in respect of any applicable Term Loans; and provided further, in the event of any inconsistency between the Register and any Lender’s records, the recordations in the Register shall govern, absent manifest error.

- 5 -

(b) Register. Administrative Agent (or its agent or sub-agent appointed by it) shall maintain at its principal office (as specified in, or as otherwise identified upon notice to the other parties hereto in accordance with, Section 12), a register for the recordation of the names and addresses of Lenders, the Term Commitments, and related principal of, and interest on, the Term Loans of each from time to time (the “Register”). The Register shall be available for inspection by Borrowers, any Lender (with respect to any entry relating to such Lender’s Term Loans) at any reasonable time and from time to time upon reasonable prior notice.

4. CREATION OF SECURITY INTEREST

4.1. Grant of Security Interest. Each of the Credit Parties hereby grants the Administrative Agent, for the ratable benefit of the Lenders, to secure the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to the Administrative Agent, for the ratable benefit of the Lenders, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Without limiting the foregoing, the Obligations shall also be secured by the Debenture creating a first-ranking continuing Lien and security interest in the Collateral and any and all other security agreements, mortgages, charges (including, without limitation, the Supplemental Debenture) granted now or in future by Horizon UK in favor of the Administrative Agent as security trustee for the Lenders.

4.2. Priority of Security Interest.

(a) Each Credit Party represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that are permitted by the terms of this Agreement to have superior priority to the Lien in favor of the Administrative Agent and the Lenders). If a Credit Party shall acquire a commercial tort claim, such Credit Party shall promptly notify the Administrative Agent in a writing signed by such Credit Party of the general details thereof and grant to the Administrative Agent, for the ratable benefit of the Lenders, in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to the Administrative Agent.

(b) Notwithstanding anything herein to the contrary, upon the receipt by the Administrative Agent of a certificate of a Responsible Officer certifying that Horizon Pharma has generated monthly sales of DUEXIS products of not less than $3,750,000 for three (3) consecutive months (the “DUEXIS Sales Target”), the security interest granted hereby by the Credit Parties with respect to the Intellectual Property Collateral shall automatically terminate, and the Administrative Agent shall promptly thereafter, at the sole cost and expense of the Credit Parties, execute and deliver to the Credit Parties all such documents and instruments as shall be necessary to evidence termination of such security interest; provided that, if a judicial authority (including a U.S. Bankruptcy Court) would hold that a security interest in the underlying Intellectual Property Collateral is necessary to have a security interest in the IP Collateral Proceeds, then the Collateral shall automatically, and effective as of the Effective Date, include the Intellectual Property Collateral to the extent necessary to permit perfection of the Administrative Agent’s security interest in such IP Collateral Proceeds.

(c) If this Agreement is terminated, the Administrative Agent’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such time as the Lenders’ obligations to make Credit Extensions has terminated, the Administrative Agent shall, at the Credit Parties’ sole cost and expense, release its Liens in the Collateral and all rights therein shall revert to the appropriate Credit Parties.

4.3. Authorization to File Financing Statements. The Credit Parties hereby authorize the Administrative Agent to file financing statements, without notice to the Credit Parties, with all appropriate jurisdictions to perfect or protect the Administrative Agent’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either the Credit Parties or any other Person, shall be deemed to violate the rights of the Administrative Agent under the Code, except dispositions permitted hereunder. Such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in the Administrative Agent’s discretion.

No Credit Party is in default under any agreement to which it is a party or by which it is bound in which the default could reasonably be expected to have a material adverse effect on such Credit Party’s business.

5.4. Binding Obligation. Each Loan Document has been duly executed and delivered by each Credit Party that is a party thereto and is the legally valid and binding obligation of such Credit Party, enforceable against such Credit Party in accordance with its respective terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or limiting creditors’ rights generally or by equitable principles relating to enforceability.

10.1. Rights and Remedies. While an Event of Default occurs and continues the Administrative Agent may, without notice or demand, do any or all of the following:

(a) declare all Obligations immediately due and payable (but if an Event of Default described in Section 9.5 occurs all Obligations are immediately due and payable without any action by the Administrative Agent);

- 24 -

(b) stop advancing money or extending credit for Borrowers’ benefit under this Agreement or under any other agreement between Borrowers and the Administrative Agent;

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

(d) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the Collateral. Borrowers shall assemble the Collateral if the Administrative Agent requests and make it available as the Administrative Agent designates. Administrative Agent 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. Borrowers grant Administrative Agent a license to enter and occupy any of their premises, without charge, to exercise any of Administrative Agent’s rights or remedies;

(e) apply to the Obligations (i) any balances and deposits of Borrowers it holds, or (ii) any amount held by Administrative Agent owing to or for the credit or the account of Borrowers;

(f) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Administrative Agent is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrowers’ labels, Patents, Copyrights, mask works, rights of use of any name, trade secrets, trade names, Trademarks, 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 Administrative Agent’s exercise of its rights under this Section, Borrowers’ rights under all licenses and all franchise agreements inure to Administrative Agent’s benefit;

(g) place a “hold” on any account maintained with Administrative Agent and/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;

(h) demand and receive possession of Borrowers’ Books; and

(i) exercise all rights and remedies available to Administrative Agent and/or any Lender under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

10.2. Power of Attorney. Each Borrower hereby irrevocably appoints Administrative Agent as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b) sign Borrower’s name on any invoice or xxxx 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 Administrative Agent 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 Administrative Agent or a third party as the Code permits. Each Borrower hereby appoints Administrative Agent as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Administrative Agent’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 and Administrative Agent is under no further obligation to make Credit Extensions hereunder. Administrative Agent’s foregoing appointment as each Borrower’s attorney in fact, and all of Administrative Agent’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed and each Lender’s obligation to provide Credit Extensions terminates.

10.3. Protective Payments. If Borrowers fail to obtain the insurance called for by Section 6.5 or fail to pay any premium thereon or fail to pay any other amount which Borrowers are obligated to pay under this Agreement or any other Loan Document, Administrative Agent may obtain such insurance or make such payment, and all amounts so paid by Administrative Agent are Lender Expenses and immediately due and payable, bearing

- 25 -

interest at the then highest rate applicable to the Obligations, and secured by the Collateral. Administrative Agent will make reasonable efforts to provide Borrowers with notice of Administrative Agent obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Administrative Agent are deemed an agreement to make similar payments in the future or Administrative Agent’s waiver of any Event of Default.

10.4. Application of Payments and Proceeds Upon Default. If an Event of Default has occurred and is continuing, Administrative Agent may 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 Administrative Agent shall determine in its sole discretion. Any surplus shall be paid to Borrowers or other Persons legally entitled thereto; Borrowers shall remain liable to Administrative Agent for any deficiency. If Administrative Agent, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Administrative Agent 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 Administrative Agent of cash therefor.

10.5. Administrative Agent’s Liability for Collateral. So long as Administrative Agent complies with reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of Administrative Agent, Administrative Agent shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrowers bear all risk of loss, damage or destruction of the Collateral.

10.6. No Waiver; Remedies Cumulative. Administrative Agent’s failure, at any time or times, to require strict performance by Borrowers of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Administrative Agent 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. Administrative Agent’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Administrative Agent has all rights and remedies provided under the Code, by law, or in equity. Administrative Agent’s exercise of one right or remedy is not an election and shall not preclude Administrative Agent from exercising any other remedy under this Agreement or other remedy available at law or in equity, and Administrative Agent’s waiver of any Event of Default is not a continuing waiver. Administrative Agent’s delay in exercising any remedy is not a waiver, election, or acquiescence.

10.7. Demand Waiver. Borrowers waive 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 Administrative Agent on which Borrowers are liable.

The Administrative Agent shall be entitled to refrain from any act or the taking of any action (including the failure to take an action) in connection herewith or any of the other Loan Documents or from the exercise of any power, discretion or authority vested in it hereunder or thereunder unless and until the Administrative Agent shall have received instructions in respect thereof from Required Lenders (or such other Lenders as may be required to give such instructions under Section 14.5) and, upon receipt of such instructions from Required Lenders (or such other Lenders, as the case may be), the Administrative Agent shall be entitled to act or (where so instructed) refrain from acting, or to exercise such power, discretion or authority, in accordance with such instructions.

The Administrative Agent and its respective Affiliates may accept deposits from, lend money to, own securities of, and generally engage in any kind of banking, trust, financial advisory or other business with Borrowers or any of their Affiliates as if it were not performing the duties specified herein, and may accept fees and other consideration from Borrowers for services in connection herewith and otherwise without having to account for the same to Lenders.

11.5. Lenders’ Representations, Warranties and Acknowledgment.

(a) Each Lender represents and warrants that it has made its own independent investigation of the financial condition and affairs of Borrowers and their Subsidiaries in connection with Credit Extensions hereunder and that it has made and shall continue to make its own appraisal of the creditworthiness of Borrowers and their Subsidiaries. The Administrative Agent shall not have any duty or responsibility, either initially or on a continuing basis, to make any such investigation or any such appraisal on behalf of Lenders or to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the making of the Term Loans or at any time or times thereafter, and the Administrative Agent shall not have any responsibility with respect to the accuracy of or the completeness of any information provided to Lenders.

If any indemnity furnished to the Administrative Agent for any purpose shall, in the opinion of the Administrative Agent, be insufficient or become impaired, the Administrative Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished; provided, in no event shall this sentence require any Lender to indemnify the Administrative Agent against any liability, obligation, loss, damage, penalty, action, judgment, suit, cost, expense or disbursement in excess of such Lender’s Pro Rata Share thereof; and provided further, this sentence shall not be deemed to require any Lender to indemnify the Administrative Agent against any liability, obligation, loss, damage, penalty, action, judgment, suit, cost, expense or disbursement described in the proviso in the immediately preceding sentence.

11.7. Successor Administrative Agent. The Administrative Agent may resign at any time by giving thirty days’ prior written notice thereof to Lenders and Borrowers, and the Administrative Agent may be removed at

Upon any such notice of resignation or any such removal, Required Lenders shall have the right, upon five Business Days’ notice to Borrowers, to appoint a successor Administrative Agent. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, that successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Administrative Agent and the resigning or removed Administrative Agent shall promptly transfer to such successor Administrative Agent all sums, together with all records and other documents necessary or appropriate in connection with the performance of the duties of the successor Administrative Agent under the Loan Documents. If the Required Lenders have not appointed a successor Administrative Agent, the Administrative Agent shall have the right to appoint a financial institution to act as Administrative Agent hereunder and in any case, the Administrative Agent’s resignation shall become effective on the thirtieth day after such notice of resignation. If neither the Required Lenders nor the Administrative Agent have appointed a successor Administrative Agent, the Required Lenders shall be deemed to succeeded to and become vested with all the rights, powers, privileges and duties of the resigning Administrative Agent. After any resigning or removed Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Section 11 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent hereunder.

11.8. Collateral Documents and Guaranty.

(a) Administrative Agent under Collateral Documents and Guaranty. Each Lender hereby further authorizes the Administrative Agent, on behalf of and for the benefit of Lenders, to be the agent for and representative of the Lenders with respect to any guaranty, the Collateral and the Collateral Documents. Subject to Section 14.5, without further written consent or authorization from any Lenders, the Administrative Agent shall, at the request and expense of Credit Parties, execute any documents or instruments necessary to, (i) in connection with a sale or disposition of assets permitted by this Agreement, release any Lien encumbering any item of Collateral that is the subject of such sale or other disposition of assets or to which Required Lenders (or such other Lenders as may be required to give such consent under Section 14.5) have otherwise consented or (ii) release any Guarantor from any guaranty or with respect to which Required Lenders (or such other Lenders as may be required to give such consent under Section 14.5) have otherwise consented.

(b) Right to Realize on Collateral and Enforce Guaranty. Anything contained in any of the Loan Documents to the contrary notwithstanding, each Credit Party, the Administrative Agent and each Lender hereby agree that (i) no Lender shall have any right individually to realize upon any of the Collateral or to enforce the Guaranty, it being understood and agreed that all powers, rights and remedies hereunder may be exercised solely by the Administrative Agent, on behalf of the Lenders in accordance with the terms hereof and all powers, rights and remedies under the Collateral Documents may be exercised solely by the Administrative Agent, and (ii) in the event of a foreclosure by the Administrative Agent on any of the Collateral pursuant to a public or private sale or other disposition, the Administrative Agent or any Lender may be the purchaser or licensor of any or all of such Collateral at any such sale or other disposition and the Administrative Agent, as agent for and representative of the Lenders (but not any Lender or Lenders in its or their respective individual capacities unless Required Lenders shall otherwise agree in writing) shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply any of the Obligations as a credit on account of the purchase price for any collateral payable by the Administrative Agent at such sale or other disposition.

11.9. Withholding Taxes.

To the extent required by any applicable law, the Administrative Agent may withhold from any payment to any Lender an amount equivalent to any applicable withholding Tax. If the Internal Revenue Service or any other Governmental Authority asserts a claim that the Administrative Agent did not properly withhold Tax from amounts paid to or for the account of any Lender because the appropriate form was not delivered or was not properly executed or because such Lender failed to notify the Administrative Agent of a change in circumstance which rendered the exemption from, or reduction of, withholding Tax ineffective or for any other reason, such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the

- 29 -

Administrative Agent as Tax or otherwise, including any penalties or interest and together with all expenses (including legal expenses, allocated internal costs and out-of-pocket expenses) incurred.

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

California law governs the Loan Documents without regard to principles of conflicts of law. Credit Parties, the Administrative Agent and Lenders each submit to the exclusive jurisdiction of the State and Federal courts in Santa Xxxxx County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude the Administrative Agent 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 the Administrative Agent, for the ratable benefit if the Lenders. 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 12 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, THE ADMINISTRATIVE AGENT, AND THE LENDERS 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 BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of Santa Xxxxx County, California Superior Court) appointed in accordance with California Code of Civil Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Xxxxx County, California; and the parties hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Santa Xxxxx County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help

- 31 -

remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

14. GENERAL PROVISIONS

The Lenders have the right, without the consent of or notice to Borrowers, to 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, the Lenders’ obligations, rights, and benefits under this Agreement and the other Loan Documents provided, however, that any such Lender Transfer (other than a transfer, pledge, sale or assignment to an Eligible Assignee) of its obligations, rights, and benefits under this Agreement and the other Loan Documents shall require the prior written consent of the Required Lenders (such approved assignee, an “Approved Lender”); provided further that provided no Event of Default has occurred and is continuing, no Lender Transfer may be made to any direct or indirect competitor of Borrowers, or any Affiliate of a competitor of Borrowers or a vulture hedge fund, in each case as determined by the Administrative Agent in its reasonable discretion, without Borrowers’ prior written consent. Borrowers and the Administrative Agent shall be entitled to continue to deal solely and directly with such Lender in connection with the interests so assigned until the Administrative Agent shall have received and accepted an effective assignment agreement in form satisfactory to the Administrative Agent executed, delivered and fully completed by the applicable parties thereto, and shall have received such other information regarding such Eligible Assignee or Approved Lender as the Administrative Agent reasonably shall require.

14.2. Indemnification.

(a) Each Credit Party agrees to indemnify, defend, pay and hold harmless the Administrative Agent, each Lender and the directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing the Administrative Agent and each Lender (each, an “Indemnified Person”) from and against any and all Indemnified Liabilities; provided, (i) no Credit Party shall have any obligation to any Indemnified Person hereunder with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise from the gross negligence or willful misconduct of that Indemnified Person, in each case, as determined by a final, non-appealable judgment of a court of competent jurisdiction, 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 applicable law, no Credit Party shall assert, and each Credit Party hereby waives, any claim against each Lender, the Administrative Agent and their respective 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, any 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 xxx upon any such claim or any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

14.3. Severability 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.

14.4. Correction of Loan Documents. The Administrative Agent may correct patent errors and fill in any blanks in the Loan Documents consistent with the agreement of the parties so long as the Administrative Agent

- 32 -

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 the Administrative Agent, Required Lenders and Credit Parties.

14.5. Amendments in Writing; Integration. (a) No amendment, 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 Borrowers therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrowers, Administrative Agent and the Required Lenders provided that

(ii) no such amendment, waiver or modification that would affect the rights and duties of Administrative Agent shall be effective without Administrative Agent’s written consent or signature;

(iii) no such amendment, waiver or other modification shall, unless signed by all the Lenders directly affected thereby, (A) reduce the principal of, rate of interest on or any fees with respect to any Term Loan or forgive any principal, interest (other than default interest) or fees (other than late charges) with respect to any Term Loan (B) postpone the date fixed for, or waive, any payment of principal of any Term Loan or of interest on any Term Loan (other than default interest) or any fees provided for hereunder (other than late charges or for any termination of any commitment); (C) change the definition of the term “Required Lenders” or the percentage of Lenders which shall be required for Lenders to take any action hereunder; (D) release all or substantially all or any material portion of the Collateral, authorize Borrower to sell or otherwise dispose of all or substantially all or any material portion of the Collateral or release any guarantor of all or any portion of the Obligations or its guaranty obligations with respect thereto, except, in each case with respect to this clause (D), as otherwise may be expressly permitted under this Agreement or the other Loan Documents (including in connection with any disposition permitted hereunder); (E) amend, waive or otherwise modify this Section 14.5 or the definitions of the terms used in this Section 14.5 insofar as the definitions affect the substance of this Section 14.5; (F) consent to the assignment, delegation or other transfer by Borrowers of any of their rights and obligations under any Loan Document or release Borrowers of their payment obligations under any Loan Document, except, in each case with respect to this clause (F), pursuant to a merger or consolidation permitted pursuant to this Agreement; (G) amend any of the provisions of Section 9.4 or amend any of the definitions Pro Rata Share, Term Loan Commitment, Commitment Percentage or that provide for the Lenders to receive their Pro Rata Shares of any fees, payments, setoffs or proceeds of Collateral hereunder; (H) subordinate the Liens granted in favor of Administrative Agent securing the Obligations; or (I) amend any of the provisions of Section 14.10. It is hereby understood and agreed that all Lenders shall be deemed directly affected by an amendment, waiver or other modification of the type described in the preceding clauses (C), (D), (E), (F), (G) and (H) of the preceding sentence;

(iv) the provisions of the foregoing clauses (i), (ii) and (iii) are subject to the provisions of any interlender or agency agreement among the Lenders and Administrative Agent pursuant to which any Lender may agree to give its consent in connection with any amendment, waiver or modification of the Loan Documents only in the event of the unanimous agreement of all Lenders.

- 33 -

14.7. Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms 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 14.2 to indemnify the Administrative Agent and the Lenders shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

14.8. Confidentiality. In handling any non-public information regarding Credit Parties and their Subsidiaries and their businesses which would reasonably be expected to be confidential, the Administrative Agent and each Lender shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to any Lender’s Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, each Lender shall use its best efforts to obtain any of its prospective transferee’s or purchaser’s agreement to the terms of this provision); (c) as required by law, regulation, subpoena, or other order; (d) to any Lender’s regulators or as otherwise required in connection with such Lender’s examination or audit; (e) as the Administrative Agent considers appropriate in exercising remedies under the Loan Documents; and (f) to third-party service providers of the Administrative Agent or any Lender so long as such service providers have executed a confidentiality agreement with the Administrative Agent or Lender, as applicable, with terms no less restrictive than those contained herein.

In addition to any rights now or hereafter granted under applicable 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, each Lender is hereby authorized by each Credit Party at any time or from time to time subject to the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed), without notice to any Credit Party or to any other Person (other than the Administrative Agent), 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 such 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 such 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) such Lender shall have made any demand hereunder or (b) the principal of or the interest on the Term Loans 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.

14.11. Marshalling; Payments Set Aside. Neither the Administrative Agent nor any Lender shall 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 the Administrative Agent or Lenders (or to the Administrative Agent, on behalf of Lenders), or the Administrative Agent or Lenders enforce any Liens or exercise their 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 and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law,

- 34 -

any other state or federal law, common law or any equitable cause, then, to the extent of such recovery, 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.

14.12. Obligations Several; Independent Nature of Lenders’ Rights. The obligations of Lenders hereunder are several and no Lender shall be responsible for the obligations or Term Commitment of any other Lender hereunder. Nothing contained herein or in any other Loan Document, and no action taken by Lenders pursuant hereto or thereto, shall be deemed to constitute Lenders as a partnership, an association, a joint venture or any other kind of entity. The amounts payable at any time hereunder to each Lender shall be a separate and independent debt, and each Lender shall be entitled to protect and enforce its rights arising out hereof and it shall not be necessary for any other Lender to be joined as an additional party in any proceeding for such purpose.

14.13. Electronic 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 applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act.

14.14. Captions. 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.

14.15. Construction of Agreement. The parties 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 caused the uncertainty to exist.

14.16. Third 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. A person who is not a party to this Agreement has no rights under the UK Contracts (Rights of Third Parties) Xxx 0000 to enforce or enjoy the benefit of this Agreement.

14.17. No Fiduciary Duty. The Administrative Agent, each Lender and their respective Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), 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 the Lenders, 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 (i) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between the Lenders, on the one hand, and such Credit Party, its Subsidiaries and their respective affiliates, on the other, (ii) in connection therewith and with the process leading to such transaction each of the Lenders 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, (iii) no Lender has 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 any 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 (iv) 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 any 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.

- 35 -

14.18. Borrower Liability. Either Borrower may, acting singly, request Term Loans hereunder. Each Borrower hereby appoints the other as agent for the other for all purposes hereunder, including with respect to requesting Term Loans hereunder. Each Borrower hereunder shall be jointly and severally obligated to repay all Term Loans made hereunder, regardless of which Borrower actually receives said Term Loan, as if each Borrower hereunder directly received all Term Loans. Each Borrower waives (a) any suretyship defenses available to it under the Code or any other applicable law, including, without limitation, the benefit of California Civil Code Section 2815 permitting revocation as to future transactions and the benefit of California Civil Code Sections 1432, 2809, 2810, 2819, 2839, 2845, 2847, 2848, 2849, 2850, and 2899 and 3433, and (b) any right to require the Administrative Agent or the Lenders to: (i) proceed against any other Borrower or any other person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. The Administrative Agent and the Lenders may exercise or not exercise any right or remedy it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting any other Borrower’s liability. Notwithstanding any other provision of this Agreement or other related document, each Borrower irrevocably waives all rights that it may have at law or in equity (including, without limitation, any law subrogating Borrower to the rights of the Administrative Agent and the Lenders under this Agreement) to seek contribution, indemnification or any other form of reimbursement from any other Borrower, or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any payment made by Borrower with respect to the Obligations in connection with this Agreement or otherwise and all rights that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by Borrower with respect to the Obligations in connection with this Agreement or otherwise. Any agreement providing for indemnification, reimbursement or any other arrangement prohibited under this Section shall be null and void. If any payment is made to a Borrower in contravention of this Section, such Borrower shall hold such payment in trust for the Administrative Agent and the Lenders and such payment shall be promptly delivered to the Administrative Agent for application to the Obligations, whether matured or unmatured.
