LOAN AND SECURITY AGREEMENT

THIS LOAN AND SECURITY AGREEMENT (this “Agreement”), dated as of April 1, 2010 (the “Effective Date”) by and among HORIZON PHARMA USA, INC., a Delaware corporation (formerly called HORIZON THERAPEUTICS, INC.) (“Horizon”), NITEC PHARMA AG, a company incorporated in Switzerland (“Nitec,” and together with Horizon, each a “Borrower” and, collectively, jointly and severally, the “Borrowers”), HORIZON PHARMA, INC., a Delaware corporation (the “Guarantor,” and, together with the Borrowers, each a “Credit Party” and, collectively, the “Credit Parties”), the Lenders listed on Appendix A hereto or otherwise party hereto from time to time, and KREOS CAPITAL III (UK) LIMITED (“Kreos”), 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.

2. LOAN AND TERMS OF PAYMENT

2.1. Promise to Pay. Borrowers hereby unconditionally promise to pay Lenders the outstanding principal amount of all Credit Extensions and accrued and unpaid interest thereon 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 severally agree that, on the Effective Date, they shall make one or more Term Loans (each, a “First Term Loan,” and collectively, the “First Term Loans”) to Borrowers in the aggregate amount of Seven Million Dollars ($7,000,000), to be allocated as between the Borrowers as the Borrowers shall determine; provided that the Borrowers shall advise the Administrative Agent of the allocation of such First Term Loans on or prior to the Funding Date for the First Term Loans. During the Second Draw Period, subject to the terms and conditions of this Agreement, the Lenders agree that they shall make one or more term loans (each, a “Second Term Loan,” and, collectively, the “Second Term Loans,” and, together with the First Term Loans, the “Term Loans”), available to Borrower in such amounts and with such allocations as may be requested by Borrowers by delivery of a Payment/Advance Form with respect to each requested Second Term Loan to the Administrative Agent in accordance with Section 3.3; provided that (i) the aggregate principal amount of all Second Term Loans made hereunder shall not exceed Five Million Dollars ($5,000,000), and (ii) all Second Term Loans made hereunder shall be made on the same Funding Date. Once repaid, a Term Loan may not be reborrowed.

(b) Pro Rata Shares. All Term Loans shall be made by Lenders simultaneously and proportionately to their respective Pro Rata Shares, it being understood that no Lender shall be responsible for any default by any other Lender in such other Lender’s obligation to make a Term Loan requested hereunder or purchase a participation required hereby nor shall any Term Commitment of any Lender be increased or decreased as a result of a default by any other Lender in such other Lender’s obligation to make a Term Loan requested hereunder or purchase a participation required hereby.

(c) Interest Rate. The principal amount outstanding under each Term Loan shall accrue interest at a fixed per annum rate equal to twelve and nine-tenths percent (12.90%) (the “Applicable Rate”). In computing interest, the date of the making of any Credit Extension shall be included and the date of payment shall be excluded; provided, however, that if any Credit Extension is repaid on the same day on which it is made, such day shall be included in computing interest on such Credit Extension. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed.

(d) Interest Payment Date. Unless otherwise provided, interest is payable monthly on the Payment Date and is included in the Monthly Payment.

(e) Repayment. Each Term Loan, inclusive of interest thereon, shall be repaid in 36 equal monthly installments, each installment to be in an amount equal to 3.33% of the original principal amount of the applicable Term Loan (with interest thereon compounding monthly) (each, a “Monthly Payment,” and collectively, the “Monthly Payments”), each as reflected on Exhibit E attached hereto, commencing on the first Payment Date following the Funding Date for the applicable Term Loan. If a Borrower fails to pay any sum to the Administrative Agent on its due date for payment, such Borrower shall pay to the Administrative Agent forthwith on demand interest on such sum (compounded on a monthly basis) from the due date to the date of actual payment at a rate equal to the Applicable Rate plus five percent (5.0%) per annum. Payment or acceptance of the increased interest rate provided in this Section 2.2(e) 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.

(f) Interim Payment. If the Funding Date for a Term Loan is not the first day of a calendar month, then on such Funding Date, the Borrower of such Term Loan shall pay to the Administrative Agent, for the ratable benefit of the Lenders, an interim loan repayment amount equal to the product determined by multiplying (i) an amount equal to the quotient determined by dividing (A) the Monthly Payment by (B) thirty (30), and (ii) the number of days comprising the period commencing on such Funding Date and ending on the first Payment Date for such Term Loan (such amount, an “Interim Payment”).

(g) Payment Allocation. Each payment made with respect to any Term Loan shall be applied first to accrued and unpaid interest thereon with the balance applied to principal.

(h) Ratable Sharing. Lenders hereby agree among themselves that if any of them shall, whether by voluntary payment, through the exercise of any right of set off or banker’s Lien, by counterclaim or cross action or by the enforcement of any right under this Agreement or otherwise, or as adequate protection of a deposit treated as cash collateral under the Bankruptcy Code, receive payment or reduction of a proportion of the aggregate amount of principal, interest, fees and other amounts then due and owing to such Lender hereunder or under the other Loan Documents (collectively, the “Aggregate Amounts Due” to such Lender) which is greater than the proportion received by any other Lender in respect of the Aggregate Amounts Due to such other Lender, then the Lender receiving such proportionately greater payment shall (a) notify the Administrative Agent and each other Lender of the receipt of such payment and (b) apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Due to the other Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion to the Aggregate Amounts Due to them; provided, if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of a Credit Party or otherwise, those purchases shall be rescinded and the purchase prices paid for such participations shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. Borrowers expressly consent to the foregoing arrangement and agree that any holder of a participation so purchased may exercise any and all rights of banker’s lien, set off or counterclaim with respect to any and all monies owing by Borrowers to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder.

(i) Advance Payment. On the Funding Date for each Term Loan, Borrowers shall pay to Lenders (by way of deduction by Lenders from the amount of such Term Loan advanced to a Borrower by Lenders on such Funding Date) an amount equal to the last Monthly Payment in respect of such Term Loan advanced (the “Advance Payment”). Lenders shall hold the Advance Payment for application to the last Monthly Payment payable in respect of the related Term Loan. Borrowers shall not be entitled to any interest in respect of any Advance Payment, nor shall any Advance Payment be subject to any set-off or other claim on the part of Borrowers.

2.3. Fees. In addition to the fees or other payments due under the Term Loans, Borrowers shall pay to the Administrative Agent, for the ratable benefit of the Lenders:

(a) Commitment Fee. A fully earned, non refundable commitment fee equal to One Hundred and Twenty Thousand Dollars ($120,000), due on the initial Funding Date (the “Commitment Fee”);

-2-

(b) Loan End Payment. A payment (the “Loan End Payment”) (in addition to and not a substitution for the regular Monthly Payments) equal to one percent (1.00%) of the aggregate principal amount of the Term Loans advanced hereunder due on the earliest of (i) the date on which the Term Loans are prepaid in full, (ii) the date on which the Term Loans are accelerated in accordance with Section 10 hereof, or (iii) the final Payment Date for the Term Loans; and

2.4. General Provisions Regarding Payments.

(a) All payments (including prepayments) made on account of the Obligations shall be made (i) without condition or deduction for any setoff, counterclaim, recoupment, or defense, in lawful money of the United States of America in immediately available same day funds, free and clear of and, subject to Section 2.7, without deduction for any Taxes, fees or other charges of any nature whatsoever imposed by any Governmental Authority (other than a Tax on the overall net income of any Lender) (and in the event any such deduction is required to be made by applicable law from any such payment, such payment shall be grossed-up so that the affected Lender receives the same amount (on an after-Tax basis) that such Lender would have received if such deduction had not been required), (ii) before 12:00 p.m. Eastern time on the date when due; and (iii) to the Administrative Agent for distribution to the Lenders in accordance with their Pro Rata Shares. For purposes of computing interest and fees, funds received by the Administrative Agent after 12:00 p.m. Eastern time on the date when due shall be deemed to have been paid by Borrower making such payment on the next succeeding Business Day. When a payment is due on a day that is not a Business Day, the payment shall be due the next Business Day, and additional fees or interest, as applicable, shall continue to accrue until paid.

(b) The Administrative Agent (or its agent or sub-agent appointed by it) shall promptly distribute to each Lender at such address as such Lender shall indicate in writing, such Lender’s applicable Pro Rata Share of all payments and prepayments of principal and interest due hereunder, together with all other amounts due thereto, including all fees payable with respect thereto, to the extent received by Administrative Agent.

(c) Each Borrower hereby authorizes the Administrative Agent to cause the Lenders to charge such Borrower’s accounts with any such Lender in order to cause timely payment to be made to Administrative Agent of all principal, interest, fees and expenses due hereunder (subject to sufficient funds being available in its accounts for that purpose).

2.5. Prepayment. Borrowers shall be entitled to prepay the amount of all outstanding Term Loans in whole (but not in part) at any time, and cancel any remaining unfunded commitment of the Lenders to make the Second Term Loans, subject to the following conditions:

(a) Borrowers shall submit to the Administrative Agent an irrevocable written request to prepay all outstanding Term Loans and cancel any such commitment at least fifteen (15) Business Days in advance indicating the aggregate amount to be paid, the amounts of such prepayment to be allocated to each outstanding Term Loan and the date of prepayment; and

(b) the prepayment sum for all outstanding Term Loans shall be equal to the aggregate sum of all Monthly Payments of principal and accrued interest thereon (as set forth in Sections 2.2(d) and 2.2(e) above), which would but for the prepayment have been paid in respect of such Term Loans throughout the remainder of the repayment term, discounted to present value at the annual rate of three percent (3.0%) per annum. For the avoidance of doubt, the Loan End Payment is due and payable without discount in accordance with Section 2.3(b).

2.6. 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:

-3-

(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 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 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 Loans made hereunder. If a Lender becomes entitled to claim any additional amounts pursuant to this Section 2.6, 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.

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 2.6 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.

2.7. Taxes; Withholding, etc.

(a) Payments to Be Free and Clear. 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 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, 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 2.7, 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 2.7 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

-4-

such Lender or the Administrative Agent in the event such Lender or the Administrative Agent is required to repay such refund or credit. This Section 2.7(a) shall not apply with respect to a Lender which was initially a Qualifying Lender but then ceases to be a Qualifying Lender.

(b) Withholding of Taxes. 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 2.7(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 2.7(b) (including without limitation any Taxes imposed by any jurisdiction on amounts payable under this Section 2.7(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 2.7 shall be made within thirty days from written demand therefor. This Section 2.7(b) shall not apply with respect to a Lender which was initially a Qualifying Lender but then ceases to be a Qualifying Lender.

(c) Evidence of Exemption From U.S. Withholding Tax. 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 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 2.7(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

2.8. 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).

(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. Administrative Agent shall record, or shall cause to be recorded, in the Register the Term Commitments and the related principal of, and interest on, the Term Loans of each Lender in accordance with the provisions of Section 14.1, and each repayment or prepayment in respect of the principal amount of the Term Loans and any such recordation shall be conclusive and binding on Borrowers and each Lender, absent manifest error; provided, 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 Term Loan. Borrowers hereby designate Administrative Agent to serve as Borrowers’ agent solely for purposes of maintaining the Register as provided in this Section 2.9, and Borrowers hereby agree that, to the extent

(b) Notwithstanding anything herein to the contrary, upon the receipt by the Administrative Agent of an Officer’s Certificate certifying that Guarantor has completed a Qualified IPO, 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 at any time on or after December 31, 2012, the Nitec Release Event occurs, and provided that no Event of Default shall have occurred and be continuing, the Credit Parties may, by written notice to the Administrative Agent, request (i) that Nitec be released as a Credit Party hereunder, (ii) that the Lien in favor of the Administrative Agent in respect of the Nitec Collateral be terminated, and (iii) that the Lien in favor of the Administrative Agent in respect of the capital stock of Nitec held by the Guarantor be limited to not more than 65% of the total combined voting power of all classes of stock entitled to vote the shares of capital stock of Nitec.

Nitec Loan Agreement; (Y) the New Nitec Loan Agreement shall contain customary cross-default provisions, such that a default under this Agreement shall be an Event of Default thereunder, and (Z) the Borrowers will treat each of the Term Loans and the New Nitec Loan Agreement as a continuation of the Term Loans as to which no gain or loss is realized for U.S. federal income Tax purposes.

(d) 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.

5. REPRESENTATIONS AND WARRANTIES

In order to induce Lenders and the Administrative Agent to enter into this Agreement and to make each Credit Extension to be made thereby, each Credit Party, jointly and severally, represents and warrants to each Lender and the Administrative Agent that the following statements are true and correct:

Schedule 5.2 correctly sets forth the ownership interest of each Credit Party in its respective Subsidiaries as of the Effective Date.

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.

-11-

5.5. Collateral. In connection with this Agreement, each Credit Party has delivered to the Administrative Agent a completed certificate signed by such Credit Party, (each, a “Perfection Certificate, and collectively, the “Perfection Certificates”). Each Credit Party represents and warrants to the Administrative Agent that:

(a) (i) its exact legal name is that indicated on its Perfection Certificate and on the signature page hereof; (ii) it is an organization of the type and is organized in the jurisdiction set forth in its Perfection Certificate; (iii) its Perfection Certificate accurately sets forth its organizational identification number or accurately states that it has none; (iv) its Perfection Certificate accurately sets forth its place of business, or, if more than one, its chief executive office as well as its mailing address (if different than its chief executive office); (v) it (and each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its jurisdiction; and (vi) all other information set forth on its Perfection Certificate pertaining to it and each of its Subsidiaries is accurate and complete (it being understood and agreed that each Credit Party may from time to time update certain information in its Perfection Certificate after the Effective Date to the extent permitted by one or more specific provisions in this Agreement). If any Credit Party is not now a Registered Organization but later becomes one, it shall promptly notify the Administrative Agent of such occurrence and provide the Administrative Agent with such Credit Party’s organizational identification number. The Administrative Agent and the Lenders hereby agree that the Perfection Certificate shall be deemed to be updated to reflect information provided in any notice delivered by any Credit Party to the Administrative Agent pursuant to the last full paragraph of Section 7.2 below; provided that any update to the Perfection Certificate by any Credit Party pursuant to the last full paragraph of Section 7.2 below shall not relieve any Credit Party of any other Obligation under this Agreement, including (without limitation) its Obligations pursuant to Section 6.7(b).

(b) (i) it has good title to, has rights in, and the power to transfer each item of the Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens, (ii) it has no deposit accounts other than the deposit accounts with Silicon Valley Bank, the deposit accounts, if any, described in the Perfection Certificate delivered to the Administrative Agent in connection herewith, or of which such Credit Party has given the Administrative Agent notice and taken such actions as are necessary to give Administrative Agent a perfected security interest therein (and upon delivery of such notice and taking such action, the Perfection Certificate will be deemed to be updated with the information contained in such notice), (iii) Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate or as permitted pursuant to Section 7.2.

To the best of its knowledge, no claim has been made that any part of its Intellectual Property violates the rights of any third party except to the extent such claim would not reasonably be expected to have a material adverse effect on its business.

(e) Except as noted on its Perfection Certificate (as the same may be updated from time to time), it is not a party to, nor is it bound by, any Restricted License.

(f) With respect to any Subsidiary that is not a Credit Party hereunder, the assets of such Subsidiary do not exceed One Million Dollars ($1,000,000), in the aggregate.

5.6. Adverse Proceedings, etc. There are no Adverse Proceedings, individually or in the aggregate, that could reasonably be expected to result in a Material Adverse Change.

-12-

writs, injunctions, decrees, rules or regulations of any court or any federal, state, municipal or other governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Change.

5.7. Financial Statements; Financial Condition. All consolidated financial statements for any Credit Party delivered to the Administrative Agent were prepared in conformity with Applicable Accounting Standards and fairly present in all material respects such Credit Party’s consolidated financial condition and such Credit Party’s consolidated results of operations.

No Credit Party has any contingent liability or liability for Taxes, long term lease (other than long-term leases entered into in the ordinary course of business) or unusual forward or long term commitment that is not reflected in the consolidated financial statements or the notes thereto and which in any such case is material in relation to the business, operations, properties, assets, or condition (financial or otherwise) of any Credit Party taken as a whole.

5.8. Solvency. As of the Effective Date, after giving effect to the transactions contemplated by this Agreement and the transaction pursuant to which the Borrowers became wholly owned Subsidiaries of Guarantor, the fair salable value of each Credit Party’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; no Credit Party is left with unreasonably small capital after the transactions in this Agreement; Nitec is not “over-indebted” (within the meaning of the applicable laws of Switzerland and Applicable Accounting Standards); and each Credit Party is able to pay its debts (including trade debts) as they mature. Without limiting the generality of the foregoing, as of the Effective Date, there has been no proposal made or resolution adopted by any competent corporate body for the dissolution or liquidation of any Credit Party, nor do any circumstances exist which may result in the dissolution or liquidation of any Credit Party. As of the Effective Date, no proposal has been made nor any resolution been adopted by any competent corporate body of any Credit Party for the statutory merger of such Credit Party with any other Person. As of the Effective Date, none of the Credit Parties has (i) made a general assignment for the benefit of creditors, (ii) filed any voluntary petition in bankruptcy or suffered the filing of an involuntary petition by any creditor, (iii) suffered the appointment of a receiver to take possession of all or any portion of its assets, (iv) suffered the attachment or judicial seizure of all or any portion of its assets, (v) admitted in writing its inability to pay its debts as they come due, nor (vi) made an offer of settlement, extension or composition to its creditors generally.

5.9. Payment of Taxes. All federal, material state, material provincial and other material Tax returns and reports (or extensions thereof) of each Credit Party and its Subsidiaries required to be filed by any of them have been timely filed, and all Taxes reflected therein which are due and payable and all assessments, fees and other governmental charges upon any Credit Party and its Subsidiaries and upon their respective properties, assets, income, businesses and franchises which are due and payable have been paid when due and payable. No Credit Party knows of any proposed Tax deficiency or assessment against it or any of its Subsidiaries which is not being actively contested by it or such Subsidiary in good faith and by appropriate proceedings; provided, such reserves or other appropriate provisions, if any, as shall be required in conformity with Applicable Accounting Standards shall have been made or provided therefor. Each Credit Party has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, and no Credit Party has withdrawn from participation in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of such Credit Party, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other Governmental Authority. Neither any Credit Party nor any of its Subsidiaries have executed or filed with the Internal Revenue Service or any other Governmental Authority any agreement or other document extending, or having the effect of extending, the period for assessment or collection of any Taxes nor has there been any request in writing for such extension. Neither any Credit Party nor any of its Subsidiaries has agreed or has been requested to make any adjustment under IRC Section 481(a) by reason of a change in accounting method or otherwise.

8. GUARANTY

8.1. Guaranty of the Obligations. Guarantor hereby irrevocably and unconditionally guaranties to the Administrative Agent, for the ratable benefit of the Lenders, the due and punctual payment in full of all Obligations when the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. § 362(a)) (collectively, the “Guaranteed Obligations”).

8.2. Payment By Guarantor. Guarantor hereby agrees, in furtherance of the foregoing and not in limitation of any other right which the Administrative Agent or any Lender may have at law or in equity against Guarantor by virtue hereof, that upon the failure of Borrowers to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. § 362(a)), Guarantor will upon demand pay, or cause to be paid, in cash, to the Administrative Agent, for the ratable benefit of the Lenders, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for Borrowers becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against Borrowers for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to the Administrative Agent or the Lenders as aforesaid.

8.3. Liability of Guarantor Absolute. Guarantor agrees that its obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without limiting the generality thereof, Guarantor agrees as follows:

(a) this Guaranty is a guaranty of payment when due and not of collectability. This Guaranty is a primary obligation of Guarantor and not merely a contract of surety;

-23-

(b) the Administrative Agent may enforce this Guaranty upon the occurrence of an Event of Default notwithstanding the existence of any dispute between Borrowers and the Administrative Agent and/or any Lender with respect to the existence of such Event of Default;

(c) the obligations of Guarantor hereunder are independent of the obligations of Borrowers and the obligations of any other guarantor of the obligations of Borrowers, and a separate action or actions may be brought and prosecuted against Guarantor whether or not any action is brought against Borrowers or any of such other guarantors and whether or not Borrowers are joined in any such action or actions;

(d) payment by Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing, if the Administrative Agent is awarded a judgment in any suit brought to enforce Guarantor’s covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit;

(e) the Administrative Agent, upon such terms as it deems appropriate, without notice or demand and without affecting the validity or enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of Guarantor’s liability hereunder, but without limiting Borrowers’ rights hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed Obligations; (iv) release, surrender, exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or modify, with or without consideration, any security for payment of the Guaranteed Obligations, any other guaranties of the Guaranteed Obligations, or any other obligation of any Person with respect to the Guaranteed Obligations; (v) enforce and apply any security now or hereafter held by or for the benefit of the Administrative Agent and/or any Lender in respect hereof or the Guaranteed Obligations and direct the order or manner of sale thereof, or exercise any other right or remedy that the Administrative Agent and/or any Lender may have against any such security, in each case as the Administrative Agent in its discretion may determine consistent herewith and any applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable, and even though such action operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of Guarantor against Borrowers or any security for the Guaranteed Obligations; and (vi) exercise any other rights available to it under the Loan Documents; and

(f) this Guaranty and the obligations of Guarantor hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or not Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to events of default) hereof, any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Loan Document or any agreement relating to such other guaranty or security; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Loan Documents or from the proceeds of any security for the Guaranteed Obligations, except to the extent such security also serves as collateral for indebtedness other than the Guaranteed Obligations) to the payment of indebtedness other than the Guaranteed Obligations, even though the Administrative Agent and/or any Lender might have elected to apply such payment to any part or all of the Guaranteed Obligations; (v) the Administrative Agent’s and/or any Lender’s consent to the change, reorganization or termination of the corporate structure or existence of any Borrower or any

-24-

of its Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (vi) any failure to perfect or continue perfection of a Lien in any collateral which secures any of the Guaranteed Obligations; (vii) any defenses, set offs or counterclaims which Borrowers may allege or assert against the Administrative Agent and/or any Lender in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury; and (viii) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an obligor in respect of the Guaranteed Obligations.

8.4. Waivers by Guarantor. Guarantor hereby waives, for the benefit of the Administrative Agent and/or the Lenders: (a) any right to require the Administrative Agent and/or the Lenders, as a condition of payment or performance by Guarantor, to (i) proceed against Borrowers, any other guarantor of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from Borrowers, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any Deposit Account or credit on the books of the Administrative Agent and/or any Lender in favor of Borrowers or any other Person, or (iv) pursue any other remedy in the power of the Administrative Agent and/or any Lender whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of Borrowers or any other guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of Borrowers or any other guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon the Administrative Agent’s and/or any Lender ‘s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting Guarantor’s liability hereunder or the enforcement hereof, (iii) any rights to set offs, recoupments and counterclaims, and (iv) promptness, diligence and any requirement that the Administrative Agent and/or any Lender protect, secure, perfect or insure any Lien or any property subject thereto; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder or any agreement or instrument related hereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to Borrowers and notices of any of the matters referred to in Section 8.3 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

8.5. Guarantor’s Rights of Subrogation, Contribution, etc. Until the Guaranteed Obligations shall have been indefeasibly paid in full and the Term Commitments shall have terminated, Guarantor hereby waives any claim, right or remedy, direct or indirect, that Guarantor now has or may hereafter have against Borrowers or any other guarantor or any of its assets in connection with this Guaranty or the performance by Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including (a) any right of subrogation, reimbursement or indemnification that Guarantor now has or may hereafter have against Borrowers with respect to the Guaranteed Obligations, (b) any right to enforce, or to participate in, any claim, right or remedy that the Administrative Agent and/or any Lender now has or may hereafter have against Borrowers, and (c) any benefit of, and any right to participate in, any collateral or security now or hereafter held by the Administrative Agent and/or any Lender. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full and the Term Commitments shall have terminated, Guarantor shall withhold exercise of any right of contribution Guarantor may have against any other guarantor of the Guaranteed Obligations. Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification Guarantor may have against Borrowers or against any collateral or security, and any rights of contribution Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights the Administrative Agent and/or any Lender may have against Borrowers, to all right, title and interest the Administrative Agent and/or any Lender may have in any such collateral or security, and to any right the Administrative Agent and/or any Lender may have against such other guarantor. If any amount shall be paid to Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for the Administrative Agent, for the ratable benefit of the Lenders, and shall forthwith be paid over to the

-25-

Administrative Agent for the ratable benefit of the Lenders to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof.

8.6. Subordination of Other Obligations. Except as provided in the following sentence, any Indebtedness of Borrowers now or hereafter held by Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations, and any such Indebtedness collected or received by the Obligee Guarantor after an Event of Default has occurred and is continuing shall be held in trust for the Administrative Agent, for the ratable benefit of the Lenders, and shall forthwith be paid over to the Administrative Agent, for the ratable benefit of the Lenders, to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof

8.7. Continuing Guaranty. This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been paid in full and the Term Commitments shall have terminated. Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations.

8.8. Authority of Guarantor or Borrowers. It is not necessary for the Administrative Agent and/or any Lender to inquire into the capacity or powers of Guarantor or Borrowers or the officers, directors or any agents acting or purporting to act on behalf of any of them.

8.9. Financial Condition of Borrowers. Any Credit Extension may be made to Borrowers or continued from time to time without notice to or authorization from Guarantor regardless of the financial or other condition of Borrowers at the time of any such grant or continuation. Neither the Administrative Agent nor any Lender shall have any obligation to disclose or discuss with Guarantor its assessment, or Guarantor’s assessment, of the financial condition of Borrowers. Guarantor has adequate means to obtain information from Borrowers on a continuing basis concerning the financial condition of Borrowers and their ability to perform their obligations under the Loan Documents, and Guarantor assumes the responsibility for being and keeping informed of the financial condition of Borrowers and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Guarantor hereby waives and relinquishes any duty on the part of the Administrative Agent and/or any Lender to disclose any matter, fact or thing relating to the business, operations or conditions of Borrowers now known or hereafter known by the Administrative Agent and/or any Lender.

8.10. Bankruptcy, etc.

(a) So long as any Guaranteed Obligations remain outstanding, Guarantor shall not, without the prior written consent of Administrative Agent acting pursuant to the instructions of Requisite Lenders, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against Borrowers. The obligations of Guarantor hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Borrowers or by any defense which Borrowers may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding.

(b) Guarantor acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to in clause (a) above (or, if interest on any portion of the Guaranteed Obligations ceases to accrue by operation of law by reason of the commencement of such case or proceeding, such interest as would have accrued on such portion of the Guaranteed Obligations if such case or proceeding had not been commenced) shall be included in the Guaranteed Obligations because it is the intention of Guarantor, the Administrative Agent and/or the Lenders that the Guaranteed Obligations which are guaranteed by Guarantor pursuant hereto should be determined without regard to any rule of law or order which may relieve Borrowers of any portion of such Guaranteed Obligations. Guarantor will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar Person to pay the Administrative Agent, or allow the claim of Administrative Agent in respect of, any such interest accruing after the date on which such case or proceeding is commenced.

(c) In the event that all or any portion of the Guaranteed Obligations are paid by Borrowers, the obligations of Guarantor hereunder shall continue and remain in full force and effect or be reinstated, as the case

-26-

may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from the Administrative Agent and/or any Lender as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder.

8.11. Discharge of Guaranty Upon Sale of Guarantor. If all of the Equity Interests of Guarantor or any of its successors in interest hereunder shall be sold or otherwise disposed of (including by merger or consolidation) in accordance with the terms and conditions hereof, the Guaranty of Guarantor or such successor in interest, as the case may be, hereunder shall automatically be discharged and released without any further action by the Administrative Agent and/or any Lender or any other Person effective as of the time of such sale or disposition.

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 bill 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 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

-29-

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.

11.1. Appointment of Administrative Agent. Kreos is hereby appointed Administrative Agent hereunder and under the other Loan Documents and each Lender hereby authorizes Kreos to act as Administrative Agent in accordance with the terms hereof and the other Loan Documents. The Administrative Agent hereby agrees to act in its capacity as such upon the express conditions contained herein and the other Loan Documents, as applicable.

11.2. Powers and Duties. Each Lender irrevocably authorizes the Administrative Agent to take such action on such Lender’s behalf and to exercise such powers, rights and remedies hereunder and under the other Loan Documents as are specifically delegated or granted to the Administrative Agent by the terms hereof and thereof, together with such powers, rights and remedies as are reasonably incidental thereto. The Administrative Agent shall have only those duties and responsibilities that are expressly specified herein and the other Loan Documents and no implied duties or responsibilities shall be read into this Agreement against the Administrative Agent. The Administrative Agent may exercise such powers, rights and remedies and perform such duties by or through its agents or employees. The Administrative Agent shall not have, by reason hereof or any of the other Loan Documents, a fiduciary relationship in respect of any Lender; and nothing herein or any of the other Loan Documents, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect hereof or any of the other Loan Documents except as expressly set forth herein or therein.

-30-

11.3. General Immunity.

(a) No Responsibility for Certain Matters. The Administrative Agent shall not be responsible to any Lender for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency hereof or any other Loan Document or for any representations, warranties, recitals or statements made herein or therein or made in any written or oral statements or in any financial or other statements, instruments, reports or certificates or any other documents furnished or made by the Administrative Agent to the Lenders or by or on behalf of any Credit Party or any Lender in connection with the Loan Documents and the transactions contemplated thereby or for the financial condition or business affairs of any Credit Party or any other Person liable for the payment of any Obligations, nor shall the Administrative Agent be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained in any of the Loan Documents or as to the existence or possible existence of any Event of Default or Default or to make any disclosures with respect to the foregoing. Anything contained herein to the contrary notwithstanding, the Administrative Agent shall not have any liability arising from confirmations of the amount of outstanding Term Loans or the component amounts thereof.

(b) Exculpatory Provisions. The Administrative Agent and any of its officers, partners, directors, employees or agents shall not be liable to the Lenders for any action taken or omitted by the Administrative Agent under or in connection with any of the Loan Documents except to the extent caused by the Administrative Agent’s gross negligence or willful misconduct, as determined by a final, non-appealable judgment of a court of competent jurisdiction. 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 Requisite Lenders (or such other Lenders as may be required to give such instructions under Section 14.5) and, upon receipt of such instructions from Requisite 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 may distribute documents, deliverables or other materials to the Lenders for acceptance or rejection, and may, upon appropriate notice, rely on the lack of an objection by Lenders as a deemed approval of the action presented. Without prejudice to the generality of the foregoing, (i) the Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any communication, instrument or document believed by it to be genuine and correct and to have been signed or sent by the proper Person or Persons and shall be entitled to rely and shall be protected in relying on opinions and judgments of attorneys (who may be attorneys for Borrowers and their Subsidiaries), accountants, experts and other professional advisors selected by it; and (ii) no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or (where so instructed) refraining from acting hereunder or any of the other Loan Documents in accordance with the instructions of Requisite Lenders (or such other Lenders as may be required to give such instructions under Section 14.5).

(c) Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers under this Agreement or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Affiliates. The exculpatory, indemnification and other provisions of this Section 11.3 and of Section 11.6 shall apply to any of the Affiliates of the Agents, and shall apply to their respective activities as Administrative Agent. All of the rights, benefits, and privileges (including the exculpatory and indemnification provisions) of this Section 11.3 and of Section 11.6 shall apply to any such sub-agent and to the Affiliates of any such sub-agent, and shall apply to their respective activities as sub-agent as if such sub-agent and Affiliates were named herein. Notwithstanding anything herein to the contrary, with respect to each sub-agent appointed by the Administrative Agent, (i) such sub-agent shall be a third party beneficiary under this Agreement with respect to all such rights, benefits and privileges (including exculpatory rights and rights to indemnification) and shall have all of the rights and benefits of a third party beneficiary, including an independent right of action to enforce such rights, benefits and privileges (including exculpatory rights and rights to indemnification) directly, without the consent or joinder of any other Person, against any or all of the Credit Parties and the Lenders, (ii) such rights, benefits and privileges (including exculpatory rights and rights to indemnification) shall not be modified or amended without the consent of such sub-agent, and (iii) such sub-agent shall only have obligations to the Administrative Agent, and not to any Credit Party, Lender or any other

-31-

Person and no Credit Party, Lender or any other Person shall have any rights, directly or indirectly, as a third party beneficiary or otherwise, against such sub-agent.

11.4. Administrative Agent Entitled to Act as Lender. The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, the Administrative Agent in its individual capacity as a Lender hereunder. With respect to its participation in the Term Loans, the Administrative Agent shall have the same rights and powers hereunder as any other Lender and may exercise the same as if it were not performing the duties and functions delegated to it hereunder, and the term “Lender” shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity. 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.

(b) Each Lender on the Effective Date shall be deemed to have acknowledged receipt of, and consented to and approved, each Loan Document and each other document required to be approved by the Administrative Agent, Requisite Lenders or Lenders, as applicable on the Effective Date.

11.6. Right to Indemnity. Each Lender, in proportion to its Pro Rata Share, severally agrees to indemnify the Administrative Agent, to the extent that the Administrative Agent shall not have been reimbursed by any Credit Party, for and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including counsel fees and disbursements) or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent in exercising its powers, rights and remedies or performing its duties hereunder or under the other Loan Documents or otherwise in its capacity as the Administrative Agent in any way relating to or arising out of this Agreement or the other Loan Documents; provided, no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct, as determined by a final, non-appealable judgment of a court of competent jurisdiction. 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 any time with or without cause by an instrument or concurrent instruments in writing delivered to Borrowers and the Administrative Agent and signed by Requisite Lenders. Upon any such notice of resignation or any such removal, Requisite 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

-32-

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 Requisite 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 Requisite Lenders nor the Administrative Agent have appointed a successor Administrative Agent, the Requisite 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) 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 the 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 Requisite Lenders (or such other Lenders as may be required to give such consent under Section 14.5) have otherwise consented or (ii) release Guarantor from the Guaranty pursuant to Section 8.11 or with respect to which Requisite 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 Requisite 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 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.

12. NOTICES

All notices, consents, requests, approvals, demands, or other communication by any party to this Agreement or any other Loan Document must be in writing and shall be deemed to have been validly served, given, or delivered: (a) upon the earlier of actual receipt and three (3) Business Days after deposit in the U.S. mail, first

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 Clara 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.

-35-

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 Clara 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 Clara 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 Clara 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 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

14.1. Successors and Assigns; Participations.

(a) Generally. This Agreement shall be binding upon the parties hereto and their respective successors and assigns and shall inure to the benefit of the parties hereto and the successors and assigns of Lenders. No Credit Party’s rights or obligations hereunder nor any interest therein may be assigned or delegated by any Credit Party without the prior written consent of all Lenders. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, Affiliates of each of the Administrative Agent and Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Register. Credit Parties, the Administrative Agent and Lenders shall deem and treat the Persons listed as Lenders in the Register as the holders and owners of the corresponding Term Commitments, and Term Loans listed therein for all purposes hereof, and no assignment or transfer of any such Term Commitment or Term Loan shall be effective, in each case, unless and until recorded in the Register following receipt of an Assignment Agreement effecting the assignment or transfer thereof, in each case, as provided in Section 14.1(d). Each assignment shall be recorded in the Register on the Business Day the Assignment Agreement is received by Administrative Agent, if received by 12:00 noon New York City time, and on the following Business Day if received after such time, prompt notice thereof shall be provided to the Credit Parties and a copy of such Assignment Agreement shall be maintained, as applicable. The date of such recordation of a transfer shall be referred to herein as the “Assignment Effective Date.” Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is listed in the Register as a Lender shall be conclusive and binding on any subsequent holder, assignee or transferee of the corresponding Term Commitments or Term Loans.

(c) Right to Assign. Each Lender shall have the right at any time to sell, assign or transfer all or a portion of its rights and obligations under this Agreement, including all or a portion of its Term Commitment or Term Loans owing to it or other Obligations (provided, however, that pro rata assignments shall not be required and each assignment shall be of a uniform, and not varying, percentage of all rights and obligations under and in respect of any applicable Term Loan and any related Term Commitments):

(d) Mechanics. Assignments and assumptions of Term Loans, and Term Commitments shall only be effected by manual execution and delivery to the Administrative Agent of an Assignment Agreement.

Subject to the terms and conditions of this Section 14.1 as of the Assignment Effective Date with respect to any Assignment Agreement (i) the assignee thereunder shall have the rights and obligations of a “Lender” hereunder to the extent of its interest in the Term Loans and Term Commitments as reflected in the Register and shall thereafter be a party hereto and a “Lender” for all purposes hereof; (ii) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned to the assignee, relinquish its rights (other than any rights which survive the termination hereof under Section 14.7) and be released from its obligations hereunder (and, in the case of an assignment covering all or the remaining portion of an assigning Lender’s rights and obligations hereunder, such Lender shall cease to be a party hereto on the Assignment Effective Date; provided, anything contained in any of the Loan Documents to the contrary notwithstanding, such assigning Lender shall continue to be entitled to the benefit of all indemnities hereunder as specified herein with respect to matters arising out of the prior involvement of such assigning Lender as a Lender hereunder); (iii) the Term Commitments shall be modified to reflect any Term Commitment of such assignee and any Term Commitment of such assigning Lender, if any; and (iv) if any such assignment occurs after the issuance of any Term Loan Note hereunder, the assigning Lender shall, upon the effectiveness of such assignment or as promptly thereafter as practicable, surrender its applicable Term Loan Notes to the Administrative Agent for cancellation, and thereupon Borrowers shall issue and deliver new Term Loan Notes, if so requested by the assignee and/or assigning Lender, to such assignee and/or to such assigning Lender, with appropriate insertions, to reflect the new Term Commitments and/or outstanding Term Loans of the assignee and/or the assigning Lender.

(g) Participations.

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.

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, 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.

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.

14.17. No Fiduciary Duty.

Each Credit Party, its Subsidiaries and their respective affiliates each 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, its Subsidiaries and their respective affiliates each acknowledge and agree 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, its Subsidiaries and their respective affiliates 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, its Subsidiaries and their respective affiliates 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.

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.
