Notwithstanding any contrary provision herein, this Section 2.05 shall not be construed to permit the Borrowers to convert any Borrowing to a Borrowing of a Type not available under the Class of Commitments or the Tranche pursuant to which such Borrowing was made.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day; and

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurocurrency Borrowing; and

(iv) if the resulting Borrowing is a Eurocurrency Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which Interest Period shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurocurrency Borrowing but does not specify an Interest Period, then the Borrowers shall be deemed to have selected an Interest Period of one month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each applicable Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If the applicable Borrower fails to deliver a timely Interest Election Request with respect to a Eurocurrency Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period, such Borrowing shall be continued as a Eurocurrency Borrowing with a one month Interest Period. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the applicable Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurocurrency Borrowing and (ii) unless repaid, each Eurocurrency Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.06Termination and Reduction of Commitments. (a) Unless previously terminated, the 2014 Term Loan Commitment of each 2014 Term Lender shall automatically and permanently terminate on the earlier of the Closing Date (after giving effect to the incurrence of 2014 Term Loans on such date) and the 2014 Term Loan Commitment Expiration Date.

(b) The Borrowers may at any time terminate, or from time to time reduce, the Commitments of any Class;provided that each reduction of such Commitments shall be in an amount that is an integral multiple of $5,000,000 and not less than $10,000,000.

(c) The Borrowers shall notify the Administrative Agent of any election to terminate or reduce the Commitments of any Class under paragraph (b) of this Section 2.06 at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrowers pursuant to this Section 2.06 shall be irrevocable;provided that a notice of termination of the Commitments of any Class

delivered by the Borrowers may state that such notice is conditioned upon the effectiveness of other credit facilities or one or more other events specified therein, in which case such notice may be revoked by each applicable Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments of any Class shall be permanent. Each reduction of the Commitments of any Class shall be made ratably among the applicable Lenders in accordance with their respective Commitments of such Class.

Section 2.07Repayment of Loans; Evidence of Debt. (a) The 2014 Term Loans shall not initially be subject to interim amortization, but, to the extent not previously repaid, all unpaid 2014 Term Loans shall be paid in full in Dollars by the U.S. Borrower on the applicable Maturity Date;provided that, to the extent specified in the applicable Extension Offer, amortization payments required with respect to Extended Loans for periods solely after the applicable Maturity Date for 2014 Term Loans shall be as specified in the applicable Extension Offer.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrowers to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Tranche under which it was made, the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the respective Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section 2.07 shall beprimafacieevidence of the existence and amounts of the obligations recorded therein;provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrowers to repay the Loans in accordance with the terms of this Agreement; provided further that in the case of any conflict between the accounts maintained pursuant to paragraph (b) and the Register, the Register shall control.

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrowers shall prepare, execute and deliver to such Lender promissory notes payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory notes and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

Section 2.08Prepayment of Loans. (a) The respective Borrowers shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to (i) the premium set forth in Section 2.09(b), (ii) the break funding payments required by Section 2.13 and (iii) subject to prior notice in accordance with the provisions of this Section 2.08(a). The applicable Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurocurrency Borrowing, not later than 11:00 a.m., New York City time, three (3) Business Days before the date of prepayment (or such later time as approved by the Administrative Agent) or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time, one (1) Business Day before the date of prepayment (or such later time as approved by the Administrative Agent). Each such notice shall be irrevocable and shall specify the prepayment date and

the principal amount of each Borrowing or portion thereof to be prepaid; provided that a notice of prepayment may state that such notice is conditioned upon the effectiveness of other credit facilities or one or more other events specified therein, in which case such notice may be revoked by each applicable Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each voluntary prepayment of a Term Loan Borrowing shall be applied as directed by the U.S. Borrower and each mandatory prepayment of a Term Loan Borrowing shall be applied in accordance with Section 2.08(c). Prepayments shall be accompanied by (i) accrued interest to the extent required by Section 2.10 and (ii) break funding payments pursuant to Section 2.13.

(b) In the event and on each occasion that (i) any Net Proceeds are received by or on behalf of Irish Holdco, any Borrower or any of their respective Restricted Subsidiaries in respect of any Prepayment Event, the Borrowers shall, within five (5) Business Days after such Net Proceeds are received, prepay the Obligations as set forth in Section 2.08(c)(i) below (and subject to Section 2.08(d)) in an aggregate amount equal to 100% of such Net Proceeds;provided that:

(1) the Borrowers may use a portion of such Net Proceeds to prepay or repurchase Permitted Pari Passu Secured Refinancing Debt to the extent any applicable credit agreement, indenture or other agreement governing such Permitted Pari Passu Secured Refinancing Debt so requires, in each case in an amount not to exceed the product of (x) the amount of such Net Proceeds and (y) a fraction, the numerator of which is the outstanding principal amount of such Permitted Pari Passu Secured Refinancing Debt and the denominator of which is the sum of the outstanding principal amount of such Permitted Pari Passu Secured Refinancing Debt and the outstanding principal amount of Term Loans; and

(2) in the case of any event described in clause (1) or (2) of the definition of the term “Prepayment Event”, if Irish Holdco shall deliver to the Administrative Agent a certificate of a Financial Officer to the effect that Irish Holdco or its Restricted Subsidiaries intend to apply the Net Proceeds from such event (or a portion thereof specified in such certificate), within 360 days after receipt of such Net Proceeds, to consummate a Permitted Acquisition or to otherwise acquire (or replace or rebuild) real property, equipment or other tangible assets (excluding inventory) to be used in the business of Irish Holdco and/or its Restricted Subsidiaries, and certifying that no Event of Default has occurred and is continuing, then no prepayment shall be required pursuant to this paragraph in respect of the Net Proceeds specified in such certificate;provided,further, that to the extent of any such Net Proceeds therefrom that have not been so applied by the end of such 360 day period (or committed to be applied by the end of the 360 day period and applied within 90 days after the end of such 360 day period), at which time a prepayment shall be required in an amount equal to such Net Proceeds that have not been so applied (subject to clause (ii) above); or

(ii) Irish Holdco or any Borrower incurs, issues or obtains any Credit Agreement Refinancing Indebtedness (other than solely by means of extending or renewing then existing Credit Agreement Refinancing Indebtedness without resulting in any Net Proceeds), the Borrowers shall, on the date on which such Credit Agreement Refinancing Indebtedness is incurred, issued or obtained, prepay any Loans constituting the applicable Refinanced Debt as set forth in Section 2.08(c)(ii) below in an aggregate amount equal to 100% of the Net Proceeds of such Credit Agreement Refinancing Indebtedness and (iii) a Change of Control occurs, the Borrowers shall make a Change of Control Offer in accordance with Section 6.10.

(c) Subject to Section 2.08(d) below and except as specified in any Extension Amendment, Incremental Amendment or Refinancing Amendment (with respect to the applicable Extended Loans or Incremental Loans or the Loans incurred pursuant to such Refinancing Amendment), (i) all such amounts pursuant to Section 2.08(b)(i) shall be applied to prepay remaining Term Loans on a pro rata basis (with each Tranche of Term Loans to receive its pro rata share of the payments pursuant to this clause (c) based on the relative outstanding principal amounts thereof), and (ii) all such amounts pursuant to Section 2.08(b)(ii) shall be applied to prepay an aggregate principal amount of the applicable Loans constituting Refinanced Debt equal to the Net Proceeds of the applicable Credit Agreement Refinancing Indebtedness.

(d) The U.S. Borrower shall notify the Administrative Agent in writing of any mandatory prepayment of Term Loans required to be made pursuant to Section 2.08(b)(i) at least five (5) Business Days prior to the date of such prepayment. Each such notice shall specify the date of such prepayment and provide a reasonably detailed calculation of the amount of such prepayment. The Administrative Agent will promptly notify each Term Lender of the contents of any such prepayment notice and of such Term Lender’s ratable portion of such prepayment (based on such Lender’s Applicable Percentage of each relevant Tranche of the Term Loans). Any Term Lender (a “Declining Term Lender,” and any Term Lender which is not a Declining Term Lender, an “Accepting Term Lender”) may elect, by delivering written notice to the Administrative Agent and the U.S. Borrower no later than 5:00 p.m. one (1) Business Day after the date of such Term Lender’s receipt of notice from the Administrative Agent regarding such prepayment, that the full amount of any mandatory prepayment otherwise required to be made with respect to the Term Loans held by such Term Lender pursuant to Section 2.08(b)(i) not be made (the aggregate amount of such prepayments declined by the Declining Term Lenders, the “Declined Prepayment Amount”). If a Term Lender fails to deliver notice setting forth such rejection of a prepayment to the Administrative Agent within the time frame specified above or such notice fails to specify the principal amount of the Term Loans to be rejected, any such failure will be deemed an acceptance of the total amount of such mandatory prepayment of Term Loans. In the event that the Declined Prepayment Amount is greater than $0, the Administrative Agent will promptly notify each Accepting Term Lender of the amount of such Declined Prepayment Amount and of any such Accepting Term Lender’s ratable portion of such Declined Prepayment Amount (based on such Lender’s Applicable Percentage in respect of the Term Loans (excluding the Applicable Percentage of Declining Term Lenders), as applicable). Any such Accepting Term Lender may elect, by delivering, no later than 5:00 p.m. one (1) Business Day after the date of such Accepting Term Lender’s receipt of notice from the Administrative Agent regarding such additional prepayment, a written notice, that such Accepting Term Lender’s ratable portion of such Declined Prepayment Amount not be applied to repay such Accepting Term Lender’s Term Loans, in which case the portion of such Declined Prepayment Amount which would otherwise have been applied to such Term Loans of the Declining Term Lenders shall instead be retained by the U.S. Borrower. Each Term Lender’s ratable portion of such Declined Prepayment Amount (unless declined by the respective Term Lender as described in the preceding sentence) shall be applied to the respective Term Loans of such Lenders. For the avoidance of doubt, the Borrowers may, at their option, apply any amounts retained in accordance with the immediately preceding sentence to prepay loans in accordance with Section 2.08(a) above.

Section 2.09Fees. (a) The Borrowers agree to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrowers and the Administrative Agent.

(b) (i) Each prepayment of the 2014 Term Loans pursuant to Section 2.08(a), Section 2.08(b)(i) (in connection with a Prepayment Event described in clause (3) of the definition thereof) or Section 2.08(b)(ii) shall be accompanied by, and (ii) if a Repricing Event with respect to the 2014 Term

Loans occurs, the Borrowers agree to pay, in the case of each of clauses (i) and (ii), a premium equal to (A) if such prepayment is made or Repricing Event occurs prior to the second anniversary of the Closing Date, the Make-Whole Amount on the 2014 Term Loans subject to such prepayment or Repricing Event as of the date of such prepayment or Repricing Event, (B) if such prepayment is made or Repricing Event occurs on or after the second anniversary of the Closing Date but prior to the third anniversary of the Closing Date, 4.00% of the principal amount of the 2014 Term Loans so prepaid or subject to such Repricing Event, (C) if such prepayment is made or Repricing Event occurs on or after the third anniversary of the Closing Date but prior to the fourth anniversary of the Closing Date, 2.00% of the principal amount of the 2014 Term Loans so prepaid or subject to such Repricing Event, and (D) if such prepayment is made or Repricing Event occurs on or after the fourth anniversary of the Closing Date, 0% of the principal amount of the 2014 Term Loans so prepaid or subject to such Repricing Event.

(c) Horizon shall pay to the Administrative Agent, for the ratable benefit and account of each applicable Lender, a ticking fee (the “Ticking Fee”) accruing from the date that is 31 days following the Effective Date through, but excluding, the earliest to occur of (i) the Closing Date, (ii) the 2014 Term Loan Commitment Expiration Date and (iii) the date of the termination of all of the 2014 Term Loan Commitments in accordance with the provisions set forth in this Agreement (such earliest date, the “Ticking Fee Payment Date”), in an amount equal to 4% per annum of the 2014 Term Loan Commitments, which rate shall increase to 8% per annum of the 2014 Term Loan Commitments on the date that is 61 days following the Effective Date. The Ticking Fee shall be payable on the Ticking Fee Payment Date.

(d) All fees payable hereunder shall be paid on the dates due, in Dollars and immediately available funds, to the Administrative Agent. Fees paid shall not be refundable under any circumstances.

Section 2.10Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin.

(b) The Loans comprising each Eurocurrency Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin.

(c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrowers hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section 2.10 or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section 2.10.

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan;provided that (i) interest accrued pursuant to paragraph (c) of this Section 2.10 shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan of any Class, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurocurrency Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a

leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

Section 2.11Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurocurrency Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by a Majority in Interest of the Lenders of any Class that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period:

then the Administrative Agent shall give notice thereof to the applicable Borrower and the applicable Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies such Borrower and the applicable Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurocurrency Borrowing shall be ineffective and any such Eurocurrency Borrowing shall be repaid on the last day of the then current Interest Period applicable thereto, and (ii) if any Borrowing Request requests a Eurocurrency Borrowing in Dollars, such Borrowing shall be made as an ABR Borrowing;provided that if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

Section 2.12Increased Costs. (a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate);

(ii) impose on any Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender; or

(iii) subject the Administrative Agent or any Lender to any Taxes (other than (A) Indemnified Taxes, (B) Other Taxes and (C) Excluded Taxes (including any change in the rate of Excluded Taxes)) with respect to this Agreement, or any Loan made by it;

and the result of any of the foregoing shall be to increase the cost to the Administrative Agent or such Lender of making or maintaining any Loan or of maintaining its obligation to make any such Loan or to reduce the amount of any sum received or receivable by the Administrative Agent or such Lender hereunder, whether of principal, interest or otherwise, then the applicable Borrower will pay to the Administrative Agent or such Lender, as the case may be, such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) If any Lender determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the

capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrowers will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) A certificate of a Lender setting forth, in reasonable detail, the basis and calculation of the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section 2.12 shall be delivered to the applicable Borrower and shall be conclusive absent manifest error. The applicable Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section 2.12 shall not constitute a waiver of such Lender’s right to demand such compensation;provided that the Borrowers shall not be required to compensate a Lender pursuant to this Section 2.12 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender notifies the applicable Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor;providedfurther that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.13Break Funding Payments. In the event of (a) the payment of any principal of any Eurocurrency Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default or as a result of any prepayment pursuant to Section 2.08), (b) the conversion of any Eurocurrency Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurocurrency Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.08(a) and is revoked in accordance therewith) or (d) the assignment of any Eurocurrency Loan other than on the last day of the Interest Period applicable thereto as a result of a request by a Borrower pursuant to Section 2.17, then, in any such event, Horizon (in the case of any failure to borrow on the Closing Date) or the Borrowers (in all other cases) shall compensate each Lender for the loss, cost and expense attributable to such event. Such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued or has been payable on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan (but not the Applicable Margin applicable thereto), for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for deposits in the relevant currency of a comparable amount and period from other banks in the eurocurrency market or other applicable market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 2.13, and setting forth in reasonable detail the calculations used by such Lender to determine such amount or amounts, shall be delivered to Horizon or the Borrowers, as applicable, and shall be conclusive absent manifest error. Horizon or the Borrowers, as applicable, shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof; provided that neither Horizon nor the Borrowers shall be required to compensate a Lender pursuant to this Section 2.13 for any amounts under this Section 2.13 incurred more than 180 days prior to the date that such Lender notifies Horizon or the Borrowers, as applicable, of such amount and of such Lender’s intention to claim compensation therefor.

Section 2.14Taxes. (a) Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made free and clear of and without deduction for any Taxes; provided that if an applicable withholding agent shall be required to deduct any Taxes from such payments, then (i) if such Taxes are Indemnified Taxes or Other Taxes, the sum payable by the applicable Loan Party shall be increased by the amount necessary so that after all required deductions (including deductions applicable to additional sums payable under this Section 2.14) each Agent and Lender receives an amount equal to the sum it would have received had no such deductions of Indemnified Taxes or Other Taxes been made, (ii) the withholding agent shall be entitled to make such deductions and (iii) the withholding agent shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Loan Parties shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Loan Parties shall jointly and severally indemnify each Agent and each Lender, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes and Other Taxes paid by such Agent or such Lender (including Indemnified Taxes and Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.14) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate setting forth in reasonable detail the basis for and calculation of such payment or liability delivered to any Borrower or Guarantor, as the case may be, by a Lender or Agent or by the Administrative Agent on its own behalf or on behalf of a Lender or Agent, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 2.14, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority (provided receipts are issued in the ordinary course by the Governmental Authority) evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any other Loan Document shall deliver to the applicable Borrowers (with a copy to the Administrative Agent), at the time(s) and in the manner(s) prescribed by applicable law or reasonably requested by any such Borrowers or the Administrative Agent, such properly completed and executed documentation as will permit such payments to be made without withholding or at a reduced rate. In addition, any Lender, if reasonably requested by U.S. Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the U.S. Borrower or the Administrative Agent as will enable the U.S. Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.14(e)(i)(A), Section 2.14(e)(i)(C), Section 2.14(e)(ii) and Section 2.14(h) below and, solely with respect to Lenders under Loans advanced to a Co-Borrower that is tax resident in the Republic of Ireland, the documentation required for the purposes of satisfying the procedural formalities referred to at paragraph (5) of the definition of Irish Qualifying Lender) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(i) Without limiting the generality of the foregoing, solely with respect to Loans extended to the U.S. Borrower,

(A) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the U.S. Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the U.S. Borrower or the Administrative Agent), whichever of the following is applicable:

(i) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN or W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii) executed originals of IRS Form W-8ECI;

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form ofExhibit G-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of U.S. Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN or W-8BEN-E; or

(iv) to the extent a Foreign Lender is not the beneficial owner of payments made to it under the Loan Documents, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form ofExhibit G-2 orExhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable;provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form ofExhibit G-4 on behalf of each such direct and indirect partner;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the U.S. Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the U.S. Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable laws as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable laws to permit the U.S. Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(C) if a payment made to the Administrative Agent or a Lender under any Loan Document would be subject to United States federal withholding Tax imposed by FATCA if the Administrative Agent or such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), the Administrative Agent or such Lender shall deliver to U.S. Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the U.S. Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the U.S. Borrower or the Administrative Agent as may be necessary for the U.S. Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that the Administrative Agent or such Lender has complied with the Administrative Agent’s or such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.14(e)(i)(C), “FATCA” shall include any amendments made to FATCA after the Closing Date.

(ii) Without limiting the generality of the foregoing, solely with respect to Loans extended to the U.S. Borrower, each Lender and Administrative Agent that is a U.S. Person shall deliver to the U.S. Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient), on or prior to the date on which such Person becomes a party to this Agreement (and from time to time thereafter upon the reasonable request of the U.S. Borrower or the Administrative Agent), properly completed and duly executed originals of IRS Form W-9 or any successor form, certifying that such Person is exempt from United States federal backup withholding Tax.

Each Lender and Administrative Agent agrees that if it becomes aware any form or certification it previously delivered pursuant to Section 2.14(e) has expired or become obsolete or inaccurate in any respect, it shall promptly update such form or certification or notify the U.S. Borrower and the Administrative Agent in writing of its legal inability to do so.

(f) If the Administrative Agent or a Lender determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified by any Borrower or Guarantor, as the case may be, or with respect to which any Borrower or Guarantor, as the case may be, has paid additional amounts pursuant to this Section 2.14, it shall pay over such refund to such Borrower or Guarantor (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower or Guarantor under this Section 2.14 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund);provided that such Borrower or Guarantor, as the case may be, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to such Borrower or Guarantor (plus any interest imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority and the requirement to repay such refund to such Governmental Authority is not due to the Administrative Agent’s or such Lender’s failure to file a timely and accurate form or certification or timely update such form or certification as required pursuant toSection 2.14(e). This Section 2.14 shall not be construed to require the Administrative Agent or any Lender to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to any Borrower, any Guarantor or any other Person. Notwithstanding anything to the contrary in this paragraph (f), in no event will the Administrative Agent or any Lender be required to pay any amount to a Borrower or Guarantor pursuant

to this paragraph (f) if the payment of which would place the Administrative Agent or such Lender in a less favorable net after-Tax position than it would have been in if the Tax subject to indemnification (or the payment of additional amounts) and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid; provided that, for the avoidance of doubt, in determining the net after-Tax position, any Taxes that would not have been imposed but for the Administrative Agent’s or such Lender’s failure, if any, to file timely and accurate forms or certifications or to timely update such forms or certifications as required pursuant to Sections 2.14(e) and 2.14(h) shall be disregarded and shall be refunded to the applicable Borrower or Guarantor.

(g) Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes and Other Taxes attributable to such Lender (but only to the extent that any Borrower or Guarantor, as the case may be, has not already indemnified the Administrative Agent for such Indemnified Taxes and Other Taxes and without limiting the obligation of each of the Borrowers and each Guarantor to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions ofSection 9.04(c)(ii) relating to the maintenance of a Participant Register, and (iii) any Excluded Taxes attributable to such Lender, in each case, that are paid or payable by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (g).

(h) (i) Every Lender under the Loans advanced to a Co-Borrower that is tax resident in the Republic of Ireland shall on or prior to the day on which such Lender becomes a Lender under this Agreement provide a confirmation in the form attached at Exhibit H (an “Irish Qualifying Lender Confirmation”). Each such Lender that becomes a Lender after the date of this Agreement shall provide, in any Assignment and Assumption which it executes on becoming a Lender and each party that becomes a Participant with respect to the Loans advanced to a Co-Borrower that is tax resident in the Republic of Ireland after the date of this Agreement shall provide, upon becoming a Participant, for the benefit of each Foreign Loan Party and Administrative Agent an Irish Qualifying Lender Confirmation.

(ii) If a Lender or Participant, as the case may be, fails to provide an Irish Qualifying Lender Confirmation in accordance with this Section 2.14(h), then such Lender or Participant, as the case may be, shall be treated for the purposes of this Agreement (including by each Foreign Loan Party) as if it is not an Irish Qualifying Lender until such time as it provides an Irish Qualifying Lender Confirmation to the Administrative Agent (and the Administrative Agent, upon receipt of such Irish Qualifying Lender Confirmation, shall inform each Foreign Loan Party). For the avoidance of doubt, an Assignment and Assumption or participation, as the case may be, shall not be invalidated by any failure of a Lender or Participant, as the case may be, to comply with this Section.

(iii) Each Lender or Participant required to provide an Irish Qualifying Lender Confirmation in accordance with this Section 2.14(h), as the case may be, shall promptly notify the Administrative Agent if there has been a change in any of the details provided in the Irish

Qualifying Lender Confirmation and provide an updated Irish Qualifying Lender Confirmation at that time and shall, for as long as it is Lender or Participant, as the case may be, at the reasonable written request by or on behalf of a Co-Borrower that is tax resident in the Republic of Ireland, provide an updated Irish Qualifying Lender Confirmation.

Section 2.15Payments Generally; Allocations of Proceeds; Pro Rata Treatment; Sharing of Set-offs. (a) Each Borrower and, if applicable, Horizon shall make each payment required to be made by it hereunder (whether of principal, interest, or fees, or of amounts payable under Section 2.12, 2.13 or 2.14, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made in Dollars to the Administrative Agent at the address specified in Section 9.01(a)(ii) or such other office as the Administrative Agent may hereafter designate in writing as such to the other parties hereto, except that payments pursuant to Sections 2.12, 2.13, 2.14 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments denominated in the same currency received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension.

(b) Any proceeds of Collateral received by the Administrative Agent (whether as a result of any realization on the Collateral, any setoff rights, any distribution in connection with any proceedings or other action of any Loan Party in respect of Debtor Relief Laws or otherwise and whether received in cash or otherwise) (i) not constituting (A) a specific payment of principal, interest, fees or other sum payable under the Loan Documents (which shall be applied on a pro rata basis among the relevant Lenders under the Class of Loans being prepaid as specified by the Borrowers) or (B) a mandatory prepayment (which shall be applied in accordance with Section 2.08) or (ii) after an Event of Default has occurred and is continuing and the Administrative Agent so elects or the Required Lenders so direct, such funds shall be applied, subject to the provisions of any Intercreditor Agreement, ratablyfirst, to pay any fees, indemnities, or expense reimbursements including amounts then due to the Administrative Agent and the Collateral Agent from the Borrowers,second, to pay any fees or expense reimbursements then due to the Lenders (in their capacities as such) from the Borrowers,third, to pay interest (including post-petition interest, whether or not an allowed claim in any Insolvency or Liquidation Proceeding) then due and payable on the Loans ratably,fourth, to prepay principal on the Loans, and any other amounts owing with respect to any pari passu Swap Obligations ratably, andfifth, to the payment of any other Secured Obligation due to any Secured Party by the Borrowers. Notwithstanding anything to the contrary contained in this Agreement, unless so directed by the respective Borrower, or unless a Default is in existence, none of the Administrative Agent or any Lender shall apply any payment which it receives to any Eurocurrency Loan, except (a) on the expiration date of the Interest Period or maturity date (as applicable) applicable to any such Eurocurrency Loan or (b) in the event, and only to the extent, that there are no outstanding ABR Loans of the same Class and, in any event, the Borrowers shall pay the break funding payment required in accordance with Section 2.13. The Administrative Agent and the Lenders shall have the continuing and exclusive right to apply and reverse and reapply any and all such received proceeds and payments to any portion of the Secured Obligations.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater

proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans;provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than, except as provided in Section 2.20, to Irish Holdco or any Subsidiary thereof (as to which the provisions of this paragraph shall apply) and (iii) nothing in this Section 2.15(c) shall be construed to limit the applicability of Section 2.15(b) in the circumstances where Section 2.15(b) is applicable in accordance with its terms. The Borrowers consent to the foregoing and agree, to the extent they may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrowers rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the applicable Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from a Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the relevant Lenders hereunder that such Borrower will not make such payment, the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the relevant Lenders the amount due. In such event, if such Borrower has not in fact made such payment, then each of the relevant Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(b), 2.15(d) or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender and for the benefit of the Administrative Agent to satisfy such Lender’s obligations to it under such Section 2.15 until all such unsatisfied obligations are fully paid and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under any such Section 2.15; in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

Section 2.16Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.12, if the Borrowers are required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14 or if any Lender delivers a notice pursuant to Section 2.22, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or 2.14, as the case may be, in the future or avoid such illegality under Section 2.22 and (ii) would not subject such Lender to any material unreimbursed cost or expense and would not otherwise be materially disadvantageous to such Lender. The Borrowers hereby jointly and severally agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If (i) any Lender requests compensation under Section 2.12, (ii) the Borrowers are required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14 or if any Lender delivers a notice pursuant to Section 2.22, or (iii) any Lender becomes a Defaulting Lender, then the respective Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under the Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment);provided that (i) the respective Borrowers shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder (including any amounts under Sections 2.13 and 2.09(b) but subject to Section 2.23(a)), from the assignee (to the extent of such outstanding principal and accrued interest and fees) or each of the applicable Borrowers (in the case of all other amounts including the fees set forth in Section 2.09(b), which shall be payable and calculated as if the Borrowers were making a prepayment to such assigning Lender), (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.14, such assignment will result in a reduction in such compensation or payments and (iv) such assignment does not conflict with applicable law. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

Section 2.17Incremental Credit Extensions. (a) The U.S. Borrower and any Co-Borrower may, by written notice to the Administrative Agent (whereupon the Administrative Agent shall promptly deliver a copy to each of the Lenders) from time to time after the Closing Date, request Incremental Term Loan Commitments and/or Incremental Revolving Commitments, as applicable, in the case of the Incremental Term Loan Commitments, denominated in Dollars, and in the case of the Incremental Revolving Commitments, denominated in Dollars or one of the Agreed Currencies, from one or more Incremental Term Lenders and/or Incremental Revolving Lenders (which, in each case, may include any existing Lender, but shall be required to be Persons which would qualify as assignees of a Lender in accordance with Section 9.04) willing to provide such Incremental Term Loans and/or Incremental Revolving Commitments, as the case may be, in their own discretion. For the avoidance of doubt, with respect to any Incremental Loans incurred by a Co-Borrower that is organized in the Republic of Ireland, each Incremental Lender shall comply with the requirements of Section 2.14, including the provision of an Irish Qualifying Lender Confirmation substantially in the form of Exhibit H (pursuant to which such Incremental Lender shall acknowledge that if it is not an Irish Qualifying Lender it will not be grossed up for any Irish withholding Tax applicable under relevant law as of the date such Incremental Lender becomes a party with respect to the Incremental Loans). Each notice provided pursuant to this Section 2.17 shall set forth (i) the type and amount of the Incremental Term Loan Commitments and/or Incremental Revolving Commitments being requested (which shall be in minimum increments of $1,000,000 and a minimum amount of $10,000,000), (ii) the date on which such Incremental Term Loan Commitments and/or Incremental Revolving Commitments are requested to become effective and (iii) to the extent constituting Incremental Term Loan Commitments, whether such Incremental Term Loan Commitments are commitments to make term loans with the same interest rates, amortization, maturity and other terms as the Class of Term Loans with the Latest Maturity Date or commitments to make term loans with interest rates and/or amortization and/or maturity and/or other terms different from such Class of Term Loans (“Other Term Loans”).

(b) The U.S. Borrower and the Co-Borrowers and each Incremental Lender shall execute and deliver to the Administrative Agent an Incremental Amendment and such other

documentation as the Administrative Agent shall reasonably specify to evidence the Incremental Commitment of such Incremental Lender. Each Incremental Amendment providing for Incremental Term Loans shall specify the terms of the applicable Incremental Term Loans;provided that (i) except as to pricing, amortization, mandatory prepayments and final maturity date (which shall, subject to clause (ii), (iii), (iv) and (vi) of this proviso, be determined by the U.S. Borrower and the Co-Borrowers and the Incremental Term Lenders in their sole discretion), the Other Term Loans shall have (x) the same terms as the Class of Term Loans with the Latest Maturity Date or (y) such other terms as shall be reasonably satisfactory to the Administrative Agent, (ii) the final maturity date of any Other Term Loans shall be no earlier than the Latest Maturity Date of any Class of Term Loans, (iii) such Class of Other Term Loans shall be denominated in Dollars and shall have no scheduled amortization payments until the Latest Maturity Date of any theretofore outstanding Class of Term Loans, (iv) the Weighted Average Life to Maturity of any Other Term Loans shall be no shorter than the remaining Weighted Average Life to Maturity of the Class of Term Loans with the Latest Maturity Date, (v) the mandatory prepayment provisions of any Other Term Loans shall not be more favorable to the lenders or holders thereof than the mandatory prepayment provisions applicable to the Term Loans and (vi) the Effective Yield of any Other Term Loans may exceed the Effective Yield then applicable to the 2014 Term Loans;provided that (x) the Effective Yield for the 2014 Term Loans is increased (to the extent necessary) such that the Effective Yield thereof is not less than the Effective Yield of such Other Term Loans minus 0.50% and (y) the Effective Yield for each other Class of Loans (unless specified otherwise in any Incremental Amendment, Refinancing Amendment or Extension Offer pursuant to which any such Class was created) is increased by a percentage per annum equal to that by which the Effective Yield of the 2014 Term Loans is (or would have been if then outstanding, if all 2014 Term Loans have been repaid in full at the time of such determination) increased pursuant to preceding clause (x). The Incremental Term Loans shall rankpari passu or junior in right of payment and of security with the Term Loans and shall not be (x) secured by any property or assets of Irish Holdco or any Subsidiary other than the Collateral or (y) guaranteed by Irish Holdco or any of its Subsidiaries other than any Guarantor; provided that, if such Incremental Term Loans rank junior in right of security with the Term Loans, such Incremental Term Loans will be established as a separate Tranche from the Term Loans. In the case of any second lien Incremental Term Loans, such Indebtedness shall be subject to the terms of a Second Lien Intercreditor Agreement. Each Incremental Amendment providing for Incremental Revolving Commitments shall specify the terms of the applicable Incremental Revolving Commitments and Incremental Revolving Loans; provided that (i) except as to pricing, commitment fees, amortization and final maturity date and other usual and customary provisions applicable to the revolving nature of the Incremental Revolving Loans (which shall, subject to clauses (ii) and (iii) of this proviso, be determined by the U.S. Borrower and the Co-Borrowers and the Incremental Revolving Lenders in their sole discretion), the Incremental Revolving Loans shall have (x) the same terms as the 2014 Term Loans or (y) such other terms as shall be reasonably satisfactory to the Administrative Agent, (ii) the final maturity date of any Incremental Revolving Loans shall be no earlier than the Latest Maturity Date of any Class of Term Loans, and (iii) such Incremental Revolving Loans shall be denominated in Dollars or one of the Agreed Currencies and shall have no scheduled amortization payments. The Incremental Revolving Loans shall rankpari passu in right of payment and of security with the Term Loans and shall not be (x) secured by any property or assets of Irish Holdco or any Subsidiary other than the Collateral or (y) guaranteed by Irish Holdco or any of its Subsidiaries other than any Guarantor.

(c) Subject to Section 2.16, each Lender may, at its option, make any Loan available to the U.S. Borrower or a Co-Borrower by causing any foreign or domestic branch or Affiliate of such Lender to make such Loan (in which case such branch or Affiliate shall be treated as the “Lender” with respect to such Loan for all purposes of this Agreement);provided that (x) any exercise of such option shall not affect the obligation of the U.S. Borrower or such Co-Borrower to repay such Loan in accordance with the terms of this Agreement, (y) if the respective branch or Affiliate is a Foreign Lender,

the same shall comply with the requirements of Section 2.14, and (z) with respect to any Loans advanced to a Co-Borrower that is tax resident in the Republic of Ireland, the Affiliate, whether or not a Foreign Lender, shall comply with the requirements of Section 2.14.

(d) Notwithstanding the foregoing, no Incremental Commitment shall become effective under this Section 2.17 unless (i) at the time that any such Incremental is made (and after giving effect thereto), (A) no Default or Event of Default shall exist;provided that, in the event that any tranche of Incremental Term Loans is used to finance a Permitted Acquisition and to the extent the Incremental Term Lenders participating in such tranche of Incremental Term Loans agree, the foregoing clause (A) shall be tested solely at the time of the execution of the acquisition agreement related to such Permitted Acquisition (provided that such Incremental Term Lenders shall not be permitted to waive any Default or Event of Default then existing or existing after giving effect to such tranche of Incremental Term Loans), and (B) the representations and warranties of the Borrowers set forth in this Agreement shall be true and correct in all material respects (other than to the extent qualified by materiality or “Material Adverse Effect”, in which case, such representations and warranties shall be true and correct);provided that, in the event that the tranche of Incremental Term Loans is used to finance a Permitted Acquisition and to the extent the Incremental Term Lenders participating in such tranche of Incremental Term Loans agree, the foregoing clause (B) shall be limited to customary “specified representations” and those representations included in the acquisition agreement related to such Permitted Acquisition that are material to the interests of the Lenders and only to the extent that Irish Holdco or its applicable Subsidiary has the right to terminate its obligations under such acquisition agreement as a result of a breach of such representations; (ii) as of the end of the most recently ended Test Period prior to the effectiveness of such Incremental Commitment (or, in the event the proceeds thereof are to be used to finance a Limited Condition Acquisition, prior to the date the definitive agreements for such Limited Condition Acquisition are entered into), both immediately before and immediately after giving effect (including pro forma effect to the use of proceeds of such Incremental Loans and any Permitted Acquisition or other acquisition or Investment to be consummated in connection therewith) to such Incremental Commitment (A) (I) the First Lien Net Leverage Ratio shall be less than 3.50:1.00 and (II) the Total Net Leverage Ratio shall be less than 5.50:1.00, assuming for the purposes of clauses (A)(I) and (A)(II) that (x) all Incremental Revolving Commitments are fully drawn, (y) all Incremental Loans and all Alternative Incremental Facility Indebtedness (and Permitted Refinancing Indebtedness with respect to the foregoing), whether or not actually secured and, if secured, whether or not actually secured on a first-lien basis, are secured on a first lien basis and (z) no proceeds of the Indebtedness to be incurred shall be included in the calculation of Unrestricted Cash with respect to such calculation; and (B) Consolidated EBITDA for such Test Period shall be greater than $70,000,000; and (iii) the Administrative Agent shall have received documents and legal opinions consistent with those delivered on the Closing Date as to such matters as are reasonably requested by the Administrative Agent. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Incremental Amendment. Each of the parties hereto hereby agrees that, upon the effectiveness of any Incremental Amendment, this Agreement shall be amended to the extent (but only to the extent) necessary to reflect the existence and terms of the Incremental Commitments (including any mechanical or other amendments necessary to reflect the establishment of the Incremental Revolving Commitments) evidenced thereby. Any such deemed amendment may be memorialized in writing by the Administrative Agent with the Borrowers’ consent (not to be unreasonably withheld, delayed or conditioned) and furnished to the other parties hereto.

(e) The Incremental Amendment may, without the consent of any Agents or Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent and the Borrowers, to effect the provisions of this Section 2.17 (including without limitation, the addition of customary Defaulting Lender provisions with respect to any Incremental Revolving Lenders). The Borrowers will use the proceeds of

the Incremental Loans for general corporate purposes (including loans and other Investments in Irish Holdco and its Subsidiaries as permitted herein, Permitted Acquisitions and Investments). Incremental Loans may be made by any existing Lender (but no existing Lender will have any obligation to make or provide any portion of any Incremental Loan) or by any other bank or other financial institution. No Lender shall be obligated to provide any Incremental Loans unless it so agrees.

(f) This Section 2.17 shall supersede any provisions in Section 2.15 or 9.02 to the contrary.

Section 2.18Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due from a Borrower hereunder in the currency expressed to be payable herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the specified currency with such other currency at the Administrative Agent’s main New York City office on the Business Day preceding that on which final,non-appealable judgment is given. The obligations of the Borrowers in respect of any sum due to any Lender or the Administrative Agent hereunder shall, notwithstanding any judgment in a currency other than the specified currency, be discharged only to the extent that on the Business Day following receipt by such Lender or the Administrative Agent (as the case may be) of any sum adjudged to be so due in such other currency such Lender or the Administrative Agent (as the case may be) may in accordance with normal, reasonable banking procedures purchase the specified currency with such other currency. If the amount of the specified currency so purchased is less than the sum originally due to such Lender or the Administrative Agent, as the case may be, in the specified currency, the applicable Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender or the Administrative Agent, as the case may be, against such loss, and if the amount of the specified currency so purchased exceeds (a) the sum originally due to any Lender or the Administrative Agent, as the case may be, in the specified currency and (b) any amounts shared with other Lenders as a result of allocations of such excess as a disproportionate payment to such Lender under Section 2.15, such Lender or the Administrative Agent, as the case may be, agrees to remit such excess to such Borrower.

Section 2.19Extensions of Loans and Commitments. (a) Notwithstanding anything to the contrary in this Agreement, pursuant to one or more offers (each, an “Extension Offer”) made from time to time by the applicable Borrower(s) to (i) all Term Lenders of Term Loans with a like Maturity Date and/or (ii) all Incremental Revolving Lenders with a like Maturity Date, in each case on a pro rata basis (based on the aggregate outstanding principal amount of the respective Loans or the aggregate amount of the Commitments with the same Maturity Date, as the case may be) and on the same terms to each such Lender, the Borrowers may from time to time offer to extend the Maturity Date for any such Loans and otherwise modify the terms of such Loans and/or Commitments pursuant to the terms of the relevant Extension Offer (including by increasing the interest rate or fees payable in respect of such Loans and/or Commitments (and related outstandings) (each, an “Extension”), and each group of Loans or Commitments, as applicable, in each case of a given Tranche as so extended, as well as the original Loans and Commitments of the original respective Tranche (in each case not so extended), shall (for the avoidance of doubt) be part of a single Tranche; and any Extended Loans shall constitute a separate Class of Loans from the Class of Loans from which they were converted, so long as the following terms are satisfied:

(i) no Default or Event of Default shall have occurred and be continuing at the time an Extension Offer is delivered to the Lenders or at the time of the Extension;

(ii) except as to interest rates, fees, amortization, final maturity date, premium, required prepayment dates and participation in prepayments (which shall, subject to the succeeding clauses (iii), (iv) and (v), be determined by the U.S. Borrower and set forth in the relevant Extension Offer), the Loans of any Term Lender extended pursuant to any Extension (“Extended Loans”) shall have the same terms as the Tranche of Loans subject to such Extension Offer;

(iii) the final maturity date for any Extended Loans shall be no earlier than the then Latest Maturity Date for the Tranche of Loans so extended;

(iv) the Weighted Average Life to Maturity of any Extended Loans shall be no shorter than the remaining Weighted Average Life to Maturity of the Term Loans extended thereby;

(v) any Extended Loans may participate on a pro rata basis or a less than pro rata basis (but not greater than a pro rata basis) in any voluntary or mandatory repayments or prepayments hereunder, in each case as specified in the respective Extension Offer;

(vi) if the aggregate principal amount of applicable Loans (calculated on the face amount thereof) in respect of which applicable Lenders shall have accepted the relevant Extension Offer shall exceed the maximum aggregate principal amount of applicable Loans, offered to be extended by the Borrowers pursuant to such Extension Offer, then the applicable Loans, of the applicable Lenders, shall be extended ratably up to such maximum amount based on the respective principal amounts (but not to exceed actual holdings of record) with respect to which such Lenders have accepted such Extension Offer;

(vii) all documentation in respect of such Extension shall be consistent with the foregoing,

(viii) the Extension shall not become effective unless, on the proposed effective date of the Extension, (x) the Borrowers shall deliver to the Administrative Agent one or more legal opinions reasonably satisfactory to the Administrative Agent and a certificate of an authorized officer of each Loan Party dated the applicable date of the Extension and executed by an authorized officer of such Loan Party certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such Extension and (y) the conditions set forth in Section 4.03 shall be satisfied (with all references in such Section 4.03 to any Borrowing being deemed to be references to the Extension on the applicable date of the Extension) and the Administrative Agent shall have received a certificate to that effect dated the applicable date of the Extension and executed by a Financial Officer of Irish Holdco and the applicable Borrower(s);

(ix) any applicable Minimum Extension Condition shall be satisfied unless waived by the Borrowers; and

(x) the Minimum Tranche Amount shall be satisfied unless waived by the Administrative Agent.

(b) With respect to all Extensions consummated by the Borrowers pursuant to this Section 2.19, (i) such Extensions shall not constitute voluntary or mandatory payments or prepayments for purposes of Sections 2.08 and (ii) no Extension Offer is required to be in any minimum amount or any minimum increment;provided that (A) the Borrowers may at their election specify as a condition (a “Minimum Extension Condition”) to consummating any such Extension that a minimum amount (to be determined and specified in the relevant Extension Offer in Borrowers’ sole discretion and may be waived by Borrowers) of Loans of any or all applicable Tranches and Classes be tendered and (B) no Tranche of Extended Loans shall be in an amount of less than $2,500,000 (the “Minimum Tranche Amount”), unless such Minimum Tranche Amount is waived by the Administrative Agent. Subject to compliance with the terms of this Section 2.19, the Administrative Agent and the Lenders hereby consent to the Extensions and the other transactions contemplated by this Section 2.19 (including, for the avoidance of doubt, payment of any interest, fees or premium in respect of any Extended Loans on such terms as may be set forth in the relevant Extension Offer) and hereby waive the requirements of any provision of this Agreement (including, without limitation, Sections 2.08 and 2.15) or any other Loan Document that may otherwise prohibit any such Extension or any other transaction contemplated by this Section 2.19.

(c) No consent of any Lender or the Administrative Agent shall be required to effectuate any Extension, other than the consent of each Lender agreeing to such Extension with respect to one or more of its Loans of any Class and/or Other Refinancing Loans (or a portion thereof). All Extended Loans and all obligations in respect thereof shall be Secured Obligations under this Agreement and the other Loan Documents that are secured by all or a portion of the Collateral on apari passu or junior lien basis with all other applicable Obligations under this Agreement and the other Loan Documents;provided that, if such Extended Loans rank junior in right of security with any other Obligations, such Extended Loans will be subject to the terms of a Second Lien Intercreditor Agreement. The Lenders hereby irrevocably authorize the Administrative Agent to enter into amendments to this Agreement and the other Loan Documents with the Borrowers as may be necessary in order to establish new Tranches or sub-tranches in respect of Term Loans so extended and such technical amendments as may be necessary or appropriate in the reasonable opinion of the Administrative Agent and the Borrowers in connection with the establishment of such new Tranches or subtranches, in each case on terms consistent with this Section 2.19 (each an “Extension Amendment”). Without limiting the foregoing, in connection with any Extensions the respective Loan Parties shall (at their expense) amend (and the Administrative Agent is hereby directed to amend) any Mortgage that has a maturity date prior to the then Latest Maturity Date so that such maturity date is extended to the then Latest Maturity Date (or such later date as may be advised by local counsel to the Administrative Agent).

(d) In connection with any Extension, the Borrowers shall provide the Administrative Agent at least ten (10) days (or such shorter period as may be agreed by the Administrative Agent) prior written notice thereof, and shall agree to such procedures, if any, as may be established by, or acceptable to, the Administrative Agent, in each case acting reasonably to accomplish the purposes of this Section 2.19.

(e) Notwithstanding anything to the contrary contained herein, no Lender shall be required to accept an Extension Offer.

Section 2.20Loan Repurchases. (a) Subject to the terms and conditions set forth or referred to below, any Borrower may from time to time, at its discretion, conduct modified Dutch auctions in order to purchase its Term Loans of one or more Classes (as determined by the applicable Borrower) (each, a “Purchase Offer”), each such Purchase Offer to be managed exclusively by the Administrative Agent (or

such other financial institution chosen by Irish Holdco and reasonably acceptable to the Administrative Agent) (in such capacity, the “Auction Manager”), so long as the following conditions are satisfied:

(i) each Purchase Offer shall be conducted in accordance with the procedures, terms and conditions set forth in this Section 2.20 and the Auction Procedures;

(ii) no Default or Event of Default shall have occurred and be continuing on the date of the delivery of each notice of an auction and at the time of (and immediately after giving effect to) the purchase of any Term Loans in connection with any Purchase Offer;

(iii) the principal amount (calculated on the face amount thereof) of each and all Classes of Term Loans that the applicable Borrower offers to purchase in any such Purchase Offer shall be no less than U.S. $10,000,000 (unless another amount is agreed to by the Administrative Agent) (across all such Classes);

(iv) after giving effect to any purchase of Term Loans of the applicable Class or Classes pursuant to this Section 2.20, Liquidity shall not be less than $50,000,000;

(v) the aggregate principal amount (calculated on the face amount thereof) of all Term Loans of the applicable Class or Classes so purchased by the applicable Borrower shall automatically be cancelled and retired by the applicable Borrower on the settlement date of the relevant purchase (and may not be resold), and in no event shall the applicable Borrower be entitled to any vote hereunder in connection with such Term Loans;

(vi) no more than one Purchase Offer with respect to any Class may be ongoing at any one time;

(vii) the applicable Borrower represents and warrants that no Loan Party shall have any material non-public information with respect to the Loan Parties or their Subsidiaries, or with respect to the Loans or the securities of any such Person, that (A) has not been previously disclosed in writing to the Administrative Agent and the Lenders (other than because such Lender does not wish to receive such material non-public information) prior to such time and (B) could reasonably be expected to have a material effect upon, or otherwise be material to, a Lender’s decision to participate in the Purchase Offer;

(viii) at the time of each purchase of Term Loans through a Purchase Offer, the applicable Borrower shall have delivered to the Auction Manager an officer’s certificate of a Responsible Officer certifying as to compliance with the preceding clause (vii); and

(ix) any Purchase Offer with respect to any Class shall be offered to all Term Lenders holding Term Loans of such Class on a pro rata basis.

(b) The applicable Borrower must terminate any Purchase Offer if it fails to satisfy one or more of the conditions set forth above which are required to be met at the time which otherwise would have been the time of purchase of Term Loans pursuant to such Purchase Offer. If the applicable Borrower commences any Purchase Offer (and all relevant requirements set forth above which are

required to be satisfied at the time of the commencement of such Purchase Offer have in fact been satisfied), and if at such time of commencement the applicable Borrower reasonably believes that all required conditions set forth above which are required to be satisfied at the time of the consummation of such Purchase Offer shall be satisfied, then the applicable Borrower shall have no liability to any Term Lender for any termination of such Purchase Offer as a result of its failure to satisfy one or more of the conditions set forth above which are required to be met at the time which otherwise would have been the time of consummation of such Purchase Offer, and any such failure shall not result in any Default or Event of Default hereunder. With respect to all purchases of Term Loans of any Class or Classes made by the Borrowers pursuant to this Section 2.20, (x) the applicable Borrower shall pay on the settlement date of each such purchase all accrued and unpaid interest (except to the extent otherwise set forth in the relevant offering documents), if any, on the purchased Term Loans of the applicable Class or Classes up to the settlement date of such purchase and (y) such purchases (and the payments made by the applicable Borrower and the cancellation of the purchased Loans, in each case in connection therewith) shall not constitute voluntary or mandatory payments or prepayments for purposes of Section 2.08 hereof.

(c) The Administrative Agent and the Lenders hereby consent to the Purchase Offers and the other transactions effected pursuant to and in accordance with the terms of this Section 2.20;provided that, notwithstanding anything to the contrary contained herein, no Lender shall have an obligation to participate in any such Purchase Offer. For the avoidance of doubt, it is understood and agreed that the provisions of Sections 2.08, 2.09, 2.13, 2.15, 6.10 and 9.04 will not apply to the purchases of Term Loans pursuant to Purchase Offers made pursuant to and in accordance with the provisions of this Section 2.20. The Auction Manager acting in its capacity as such hereunder shall be entitled to the benefits of the provisions of Article VIII and Section 9.03 to the same extent as if each reference therein to the “Agents” were a reference to the Auction Manager, and the Administrative Agent shall cooperate with the Auction Manager as reasonably requested by the Auction Manager in order to enable it to perform its responsibilities and duties in connection with each Purchase Offer.

(d) This Section 2.20 shall supersede any provisions in Section 2.15 or 9.02 to the contrary.

Section 2.21Refinancing Amendment. At any time after the Closing Date, the Borrowers may obtain, from any Lender or any Refinancing Lender, Credit Agreement Refinancing Indebtedness in respect of all or any portion of the Loans or Commitments of such Borrowers then outstanding under this Agreement, in the form of Other Refinancing Loans or Other Refinancing Commitments in each case pursuant to a Refinancing Amendment; provided that such Credit Agreement Refinancing Indebtedness (i) will rank pari passu or, other than in the case of Other Refinancing Revolving Commitments and Other Refinancing Revolving Loans, junior in right of payment and of security with the other Loans and Commitments hereunder; provided that, if such Credit Agreement Refinancing Indebtedness ranks junior in right of security with any other Loans or Commitments hereunder, such Credit Agreement Refinancing Indebtedness will be subject to the terms of a Second Lien Intercreditor Agreement, (ii) will have such maturity dates, pricing, premiums and optional prepayment or redemption terms as may be agreed by the Borrowers and the Lenders thereof; and (iii) will otherwise comply with the proviso to the definition of Credit Agreement Refinancing Indebtedness; provided further that any Person that provides any Credit Agreement Refinancing Indebtedness in the form of Other Refinancing Loans or Other Refinancing Commitments to a Co-Borrower that is organized in the Republic of Ireland shall comply with the requirements of Section 2.14, including the provision of an Irish Qualifying Lender Confirmation substantially in the form of Exhibit H (pursuant to which such Person shall acknowledge that if it is not an Irish Qualifying Lender it will not be grossed up for any Irish withholding Tax applicable under relevant law as of the date such Person provides such Credit Agreement Refinancing Indebtedness). Any Other Refinancing Loans or Other Refinancing Commitments, as applicable, may participate on a pro rata basis

or on a less than pro rata basis (but not on a greater than pro rata basis) in any voluntary or mandatory prepayments hereunder, as specified in the applicable Refinancing Amendment. The effectiveness of any Refinancing Amendment shall be subject to the satisfaction on the date thereof of each of the conditions set forth in Section 4.03 and, to the extent reasonably requested by the Administrative Agent, receipt by the Administrative Agent of legal opinions, board resolutions, officers’ certificates and/or reaffirmation agreements generally consistent with those delivered on the Closing Date pursuant to Sections 4.02(b) and (f) (other than changes to such legal opinions resulting from a change in law, change in fact or change to counsel’s form of opinion reasonably satisfactory to the Administrative Agent). Each incurrence of Credit Agreement Refinancing Indebtedness pursuant to this Section 2.21 shall be in an aggregate principal amount that is not less than $5,000,000. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Refinancing Amendment. Each of the parties hereto hereby agrees that, upon the effectiveness of any Refinancing Amendment, this Agreement shall be deemed amended to the extent (but only to the extent) necessary to reflect the existence and terms of the Credit Agreement Refinancing Indebtedness incurred pursuant thereto (including any amendments necessary to treat the Loans and Commitments subject thereto as Other Refinancing Term Loans and/or Other Refinancing Term Commitments). Any Refinancing Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent and the Borrowers, to effect the provisions of this Section 2.21 (including without limitation, the addition of customary Defaulting Lender provisions with respect to any Lenders providing Other Refinancing Revolving Loans and Other Refinancing Revolving Commitments). This Section 2.21 shall supersede any provisions in Section 2.15 or 9.02 to the contrary.

Section 2.22Illegality. If any Lender determines that any law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain or fund Loans whose interest is determined by reference to the LIBO Rate, or to determine or charge interest rates based upon the LIBO Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the Borrowers through the Administrative Agent, (i) any obligation of such Lender to make or continue Eurocurrency Loans or to convert ABR Loans to Eurocurrency Loans shall be suspended and (ii) if such notice asserts the illegality of such Lender making or maintaining ABR Loans the interest rate on which is determined by reference to the Adjusted LIBO Rate component of the Alternate Base Rate, the interest rate on which ABR Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Adjusted LIBO Rate component of the Alternate Base Rate. Upon receipt of such notice, (x) the applicable Borrowers shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurocurrency Loans of such Lender to ABR Loans (the interest rate on which ABR Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Adjusted LIBO Rate component of the Alternate Base Rate), either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurocurrency Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurocurrency Loan and (y) if such notice asserts the illegality of such Lender determining or charging interest rates based upon (A) the LIBO Rate, the Administrative Agent shall during the period of such suspension compute the Alternate Base Rate applicable to such Lender without reference to the Adjusted LIBO Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the LIBO Rate. Upon any such prepayment or conversion, the applicable Borrower shall also pay accrued interest on the amount so prepaid or converted.

Section 2.23Defaulting Lenders.

(a) Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(1) such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders; and

(2) no Defaulting Lender shall be entitled to receive any ticking fee pursuant to Section 2.09(c) (and the U.S. Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(b) Defaulting Lender Cure. If a Lender ceases to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any cash collateral), that Lender will, to the extent applicable, take such actions as the Administrative Agent may determine to be necessary to cause the applicable Loans to be held pro rata by the applicable Lenders in accordance with the applicable Commitments, whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of Horizon or the Borrowers while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

ARTICLE III

Representations and Warranties

In order to induce the Administrative Agent and the Lenders to enter into this Agreement on the Effective Date and to make each Loan or other extension of credit to be made hereunder on the Closing Date and on the date of each other Borrowing, each of Irish Holdco and the Borrowers represents and warrants to the Administrative Agent and Lenders that, on the Closing Date (after giving effect to the Transactions) and on the date of each other Borrowing, that each of the following statements are true and correct in all material respects:

Section 3.01Organization; Powers; Subsidiaries. Each of Irish Holdco and its Material Subsidiaries is duly organized or incorporated, as the case may be, and validly existing and (to the extent the concept is applicable in such jurisdiction) in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and (to the extent the concept is applicable in such jurisdiction) is in good standing in, every jurisdiction where such qualification is required. Schedule 3.01 hereto identifies each Subsidiary (other than Subsidiaries in respect of which Irish Holdco and its Subsidiaries own less than 50% of the Equity Interests thereof) as of the Closing Date, noting whether such Subsidiary is a Material Subsidiary, whether such Subsidiary is an Unrestricted Subsidiary, the jurisdiction of its incorporation or organization, as the case may be, the percentage of issued and outstanding shares of each class of its capital stock or other equity interests owned by Irish Holdco and the other Subsidiaries and, if such percentage is not 100% (excluding directors’ qualifying shares as required by law), a description of each class issued and outstanding. All of the outstanding shares of capital stock and other equity interests of each Material Subsidiary are validly issued and outstanding and fully paid and non-assessable and all such shares and other equity interests owned by Irish Holdco or

another Material Subsidiary are owned, beneficially and of record, by Irish Holdco or such Material Subsidiary free and clear of all Liens, other than Liens created under the Loan Documents and Liens permitted by Section 6.02. As of the Closing Date (and except pursuant to the Acquisition Agreement), there are no outstanding commitments or other obligations of any Material Subsidiary to issue, and no options, warrants or other rights of any Person to acquire, any shares of any class of capital stock or other equity interests of any Material Subsidiary.

Section 3.02Authorization; Enforceability. The Transactions are within each Loan Party’s corporate or other organizational powers and have been (or, except with respect to the Loan Documents executed by one or more Loan Parties on the Closing Date, will on or prior to the Closing Date be) duly authorized by all necessary corporate or other organizational actions and, if required, actions by shareholders, members or equity holders. The Loan Documents and Acquisition Documentation to which each Loan Party is a party have been duly executed and delivered by such Loan Party and constitute a legal, valid and binding obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

Section 3.03Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect and except for (x) filings or registrations necessary to perfect Liens created pursuant to the Loan Documents, (y) filings or registrations required in connection with the White Wash Requirements and (z) consents, approvals, registrations, filings or other actions that will be obtained or made in connection with the Acquisition and each other transaction contemplated by the Reorganization on or prior to the Closing Date, (b) will not violate any applicable law or regulation (except such non-compliance that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect) or the charter, by-laws or other organizational documents of Irish Holdco or any of its Material Subsidiaries or any order of any Governmental Authority, (c) will not violate in any material respect or result in a default under any indenture, material agreement or other material instrument binding upon Irish Holdco or any of its Material Subsidiaries or its assets, or give rise to a right thereunder to require any payment to be made by Irish Holdco or any of its Material Subsidiaries (other than the Indebtedness set forth on Schedule 3.03), and (d) will not result in the creation or imposition of any Lien on any asset of Irish Holdco or any of its Material Subsidiaries, other than Liens created under the Loan Documents.

Section 3.04Financial Condition; No Material Adverse Change. (a) Horizon has heretofore furnished to the Lenders (i) the combined balance sheet and statements of operations, changes in shareholders’ equity and cash flows as of and for the fiscal years ended December 31, 2012 and December 31, 2013 for Target and its Subsidiaries and Vidara Therapeutics Inc., reported on by Halif, Arogeti & Wynne LLP, (ii) the consolidated balance sheet and statements of comprehensive loss, stockholders’ equity (loss) and cash flows as of and for the fiscal years ended December 31, 2011, December 31, 2012 and December 31, 2013 for Horizon and its Subsidiaries, reported on by PricewaterhouseCoopers LLP, (iii) the unaudited combined balance sheet and statements of operations and cash flows as of and for the three-month period ended on March 31, 2014 for Target and its Subsidiaries and Vidara Therapeutics Inc., and (iv) the unaudited condensed consolidated balance sheet and statements of comprehensive loss and cash flows as of and for the three-month period ended on March 31, 2014 for Horizon and its Subsidiaries. Such financial statements present fairly, in all material respects, the combined financial position and results of operations and cash flows of Target and its Subsidiaries and Vidara Therapeutics Inc. and the financial position and results of operations and cash flows of Horizon and its consolidated Subsidiaries, as the case may be, as of such dates and for such

periods in accordance with GAAP subject, in the case of clauses (iii) and (iv) of the immediately preceding sentence, to normal year-end audit adjustments and the absence of footnotes.

(b) Since December 31, 2013 (for this purpose, assuming that the Transaction had been consummated before December 31, 2013), there has been no material adverse change in the business, assets, operations or condition, financial or otherwise, of Irish Holdco and its respective Subsidiaries, taken as a whole.

Section 3.05Properties. (a) Each of Irish Holdco, the Borrowers and their respective Material Subsidiaries has good title to, or (to the knowledge of any of Irish Holdco and the Borrowers) valid leasehold interests in, all its real and personal property (excluding intellectual property, which is considered in Section 3.05(b)) material to its business, except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes.

(b) Each of Irish Holdco, the Borrowers and their respective Restricted Subsidiaries owns without restriction, free and clear of all Liens other than Permitted Liens, or is licensed to use, all trademarks, trade names, copyrights, patents and other intellectual property used in or necessary to the business of Irish Holdco and its Subsidiaries, except as would not reasonably be expected to have a Material Adverse Effect. All such intellectual property is, to the knowledge of any of Irish Holdco and the Borrowers, valid and enforceable and all registrations and applications for such intellectual property are, to the knowledge of any of Irish Holdco and the Borrowers (to the extent such intellectual property is licensed from third parties), subsisting and have not expired or been abandoned except as could not reasonably be expected to have a Material Adverse Effect. Except as set forth in Schedule 3.05 attached hereto, Vidara’s registration statement on Form S-4 and any filings incorporated by reference therein (including Horizon’s Annual Report on Form 10-K for the year ended December 31, 2013 and Horizon’s quarterly report on Form 10-Q for the quarter ended March 31, 2014) no claim has been asserted and is pending by any Person challenging or questioning the use of any such intellectual property or the validity or effectiveness of any such intellectual property, nor do Irish Holdco and the Borrowers know of any valid basis for any such claim, except for such claims that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

Section 3.06Litigation, Environmental and Labor Matters. (a) Except as set forth onSchedule 3.06 hereto, Vidara’s registration statement on Form S-4, Horizon’s Annual Report on Form 10-K for the year ended December 31, 2013 and Horizon’s quarterly report on Form 10-Q for the quarter ended March 31, 2014, there are no actions, suits, proceedings or investigations by or before any arbitrator or Governmental Authority pending against or, to the knowledge of any of Irish Holdco and the Borrowers, threatened against or affecting Irish Holdco or any of its Subsidiaries that could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. Since March 31, 2014, as of the date hereof, there have been no developments in any of the matters disclosed in Schedule 3.06 or in the registration statement or the Annual or Quarterly Reports described above which could reasonably be expected, individually or in the aggregate with any such other matters or any additional actions, suits, proceedings or investigations, to result in a Material Adverse Effect.

(b) Except with respect to matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, (A) neither Irish Holdco nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) is subject to any Environmental Liability or (iii) has received written notice of any pending or threatened claim with respect to any Environmental Liability; and (B) no Hazardous Materials are present at or have been Released at, in, on or under any real property (including real property formerly owned or operated by

Irish Holdco or their respective Subsidiaries, or any location where Hazardous Materials have been sent for re-use, recycling, treatment, storage or disposal) that would reasonably be expected to give rise to any Environmental Liability of Irish Holdco or any of its respective Subsidiaries.

(c) As of the Closing Date, there are no strikes, lockouts or slowdowns against Irish Holdco or any of its Subsidiaries pending or, to the knowledge of any of Irish Holdco and the Borrowers, threatened that have resulted in, or could reasonably be expected to result in, a Material Adverse Effect. The hours worked by and payments made to employees of Irish Holdco and its Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable Federal, state, local or foreign law relating to such matters that has resulted in, or could reasonably be expected to result in, a Material Adverse Effect. All material payments due from Irish Holdco or any of its Subsidiaries, or for which any claim may be made against Irish Holdco or any of its Subsidiaries, on account of wages and employee health and welfare insurance and other benefits, have been paid or accrued as liabilities on the books of Irish Holdco or such Subsidiary except to the extent that the failure to do so has not resulted in, and could not reasonably be expected to result in, a Material Adverse Effect. The consummation of the Transactions will not give rise to any right of termination or right of renegotiation on the part of any union under any collective bargaining agreement under which Irish Holdco the Borrowers or any of their respective Material Subsidiaries is bound.

Section 3.07Compliance with Laws and Agreements. Except as set forth inSchedule 3.07 hereto, each of Irish Holdco and its Subsidiaries is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property, operations or assets and all indentures, agreements and other instruments binding upon it or its property, except where such non-compliance would not reasonably be expected to result, individually or in the aggregate, in a Material Adverse Effect.

Section 3.08Investment Company Status. Neither Irish Holdco, the Borrowers nor any of their respective Restricted Subsidiaries is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

Section 3.09Taxes. Each of Irish Holdco and its Subsidiaries has timely filed or caused to be filed all federal income Tax returns and all other material Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except Taxes that are being contested in good faith by appropriate proceedings and for which Irish Holdco or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with, and to the extent required by, applicable accounting principles. Any Borrower that is not organized in the Republic of Ireland is not tax resident in the Republic of Ireland.

Section 3.10ERISA.

(a) Except as set forth onSchedule 3.10, each of Irish Holdco and its ERISA Affiliates are in compliance in all material respects with the applicable provisions of ERISA and the Code and the regulations and published interpretations thereunder, and, except as could not reasonably be expected to result in material liability to any Loan Party, all contributions required to be made under the terms of any Plan as of the date of this Agreement have been timely made on, or if not yet due, have been properly reflected on the most recent consolidated balance sheet filed or incorporated by reference in the Companies’ financial statements.

(b) No ERISA Event has occurred or is reasonably expected to occur that, in each case, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in material liability of Irish Holdco or any of its ERISA Affiliates.

(c) Except as set forth onSchedule 3.10, to the knowledge of any of Irish Holdco and the Borrowers there has been no prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code and other than a transaction that is exempt under a statutory or administrative exemption) with respect to any Plan that could result in material liability to any Loan Party.

(d) As of the Closing Date, the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans.

(e) Using actuarial assumptions and computation methods consistent with Part 1 of Subtitle E of Title IV of ERISA, the aggregate liabilities of each Loan Party or its ERISA Affiliates to all Multiemployer Plans in the event of a complete withdrawal therefrom, as of the close of the most recent fiscal year of each such Multiemployer Plan, could not reasonably be expected to result in a Material Adverse Effect.

(f) Each Non-U.S. Plan has been maintained in compliance in all material respects with its terms and with the requirements of any and all applicable laws, statutes, rules, regulations and orders and has been maintained, where required, in good standing with applicable regulatory authorities. All contributions required to be made with respect to a Non-U.S. Plan have been timely made, except as would not reasonably be expected to result in a Material Adverse Effect. Neither Irish Holdco nor any of its Subsidiaries has incurred any obligation in connection with the termination of, or withdrawal from, any Non-U.S. Plan, except as would not reasonably be expected to result in a Material Adverse Effect. With respect to each Non-U.S. Plan, neither Irish Holdco nor any of its ERISA Affiliates or any of their respective directors, officers, employees or agents has engaged in a transaction which would subject Irish Holdco or any Subsidiary, directly or indirectly, to a tax or civil penalty which could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. With respect to each Non-U.S. Plan, reserves have been established in the financial statements furnished to Lenders in respect of any unfunded liabilities in accordance with applicable law or, where required, in accordance with ordinary accounting practices in the jurisdiction in which such Non-U.S. Plan is maintained.

(r) A Borrowing Request shall have been delivered in accordance with the terms of Section 2.03.

Notwithstanding anything in this Agreement to the contrary it is understood that, to the extent any security interest in the Collateral (other than (1) any Collateral the security interest in which may be perfected by the filing of a UCC financing statement, (2) with respect to the U.S. Borrower and the Domestic Subsidiaries that are Subsidiary Guarantors by intellectual property filings with the United

(b) Except as set forth in Section 2.17(d) with respect to Incremental Term Loans used to finance a Permitted Acquisition, at the time of and immediately after giving effect to such Borrowing, no Default shall have occurred and be continuing.

The designation of any Restricted Subsidiary as an Unrestricted Subsidiary after the Closing Date shall constitute an Investment by the applicable Loan Party therein at the date of designation in an amount equal to the fair market value (as determined in good faith by Irish Holdco) of the applicable Loan Party’s (or any of its Restricted Subsidiaries’) investment therein. The designation of any Unrestricted Subsidiary as a Restricted Subsidiary after the Closing Date shall constitute (i) the incurrence at the time of designation of any Investment, Indebtedness or Liens of such Subsidiary existing at such time and (ii) a return on any Investment by the applicable Loan Party in Unrestricted Subsidiaries pursuant to the preceding sentence in an amount equal to the fair market value at the date of such designation of such Loan Party’s Investment in such Subsidiary.

(ii) pay the Change of Control Payment in respect of all Loans being repaid in accordance with Section 2.15.

Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

(a) either:

(i) a Loan Party is the surviving corporation; or

(ii) the Person formed by or surviving any such consolidation or merger (if other than a Loan Party) or to which such sale, assignment, transfer, conveyance, lease or other disposition has been made is an entity organized or existing under the laws of the United States, any state of the United States or the District of Columbia, Luxembourg or, other than in the case of the U.S. Borrower or any Co-Borrower not organized under the laws of Ireland, Ireland or, in the case of a merger or consolidation of a Loan Party (other

114

than Irish Holdco, the U.S. Borrower or a Co-Borrower) with or into another Person, the jurisdiction of such Loan Party;

(b) the Person formed by or surviving any such consolidation or merger (if other than a Loan Party) or the Person to which such sale, assignment, transfer, conveyance, lease or other disposition has been made (if other than a Loan Party) assumes all the obligations of the Loan Party under this Agreement pursuant to agreements reasonably satisfactory to the Administrative Agent;

Sections 6.11(c) and 6.11(d) will not apply to any merger or consolidation of any Loan Party with or into an Affiliate solely for the purpose of reincorporating Irish Holdco in another jurisdiction.

ARTICLE VIII

The Agents

Each of the Lenders hereby irrevocably appoints Citibank, N.A. as its administrative agent and authorizes Citibank, N.A. to take such actions on its behalf, including execution of the other Loan Documents, and to exercise such powers as are delegated to the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto, and Citibank, N.A. hereby accepts such appointment.

Citibank, N.A. or an Affiliate or designee thereof shall also act as the Collateral Agent under the Loan Documents (for purposes of this Article VIII and Sections 9.03 and 2.14, the Administrative Agent and the Collateral Agent shall be collectively referred to as the “Agents”), and each of the Lenders hereby irrevocably appoints and authorizes Citibank, N.A. (and Citibank, N.A. hereby accepts such appointment) and each such Affiliate and designee to act as the agent of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Secured Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, any co-agents, sub-agents and attorneys-in-fact appointed by the Collateral Agent pursuant to this Article VIII for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent, shall be entitled to the benefits of all provisions of this Article VIII and Article IX (including Section 9.03), as though such co-agents, sub-agents and attorneys-in-fact were the Collateral Agent under the Loan Documents as if set forth in full herein with respect thereto.

The banks serving as the Agents hereunder shall have the same rights and powers in their capacity as Lenders as any other Lender and may exercise the same as though they were not an Agent, and such banks and their Affiliates may accept deposits from, lend money to and generally engage in any

118

kind of business with Irish Holdco or any Subsidiary or other Affiliate thereof as if they were not an Agent hereunder.

The Agents shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Agents shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Agents shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the respective Agent is required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth in the Loan Documents, the Agents shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Irish Holdco or any of its Subsidiaries that is communicated to or obtained by any bank serving as an Agent or any of its Affiliates in any capacity. The Agents shall not be liable for any action taken or not taken by them with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02 or elsewhere in the Loan Documents) or in the absence of its own gross negligence or willful misconduct. The Agents shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the respective Agent by Irish Holdco, a Borrower or a Lender, and no Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or in connection with any Loan Document, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, (v) the creation, perfection or priority of Liens on the Collateral or the existence of the Collateral or (vi) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to such Agent.

The Agents shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by them to be genuine and to have been signed or sent by the proper Person. The Agents also may rely upon any statement made to them orally or by telephone and believed by them to be made by the proper Person, and shall not incur any liability for relying thereon. The Agents may consult with legal counsel (who may be counsel for Irish Holdco, Irish Intermediate Holdco, Irish New Intermediate Holdco or the Borrowers), independent accountants and other experts selected by them, and shall not be liable for any action taken or not taken by them in accordance with the advice of any such counsel, accountants or experts.

The Agents may perform any and all their duties and exercise their rights and powers by or through any one or more sub-agents appointed by the respective Agent. The Agents and any such sub-agent may perform any and all their duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Agents and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as an Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrowers. Upon any such resignation, the Required Lenders shall have the right (with the consent of the Borrowers (such consent not to be unreasonably withheld or delayed),provided that no consent of the Borrowers shall be required if an Event of Default under clause (a), (b), (h), (i) or (j) of Article VII has

119

occurred and is continuing) to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article VIII and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Subject to the appointment and acceptance of a successor Collateral Agent as provided in this paragraph, the Collateral Agent may resign at any time by notifying the Lenders and the Borrowers. Upon any such resignation, the Required Lenders shall have the right (with the consent of the Borrowers (such consent not to be unreasonably withheld or delayed);provided that no consent of the Borrowers shall be required if an Event of Default under clause (a), (b), (h), (i) or (j) of Article VII has occurred and is continuing) to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Lenders, appoint a successor Collateral Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Collateral Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the Collateral Agent’s resignation hereunder, the provisions of this Article VIII and Section 9.03 shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Collateral Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Agents or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agents or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

None of the Lenders, if any, identified in this Agreement as a Lead Arranger, a Co-Documentation Agent or a Co-Syndication Agent shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of such Lenders shall have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgments with respect to the relevant Lenders in their respective capacities as a Lead Arranger, Co-Documentation Agent and/or Co-Syndication Agent, as applicable, as it makes with respect to the Agents in the preceding paragraph.

The Lenders are not partners or co-venturers, and no Lender shall be liable for the acts or omissions of, or (except as otherwise set forth herein in case of the Agents) authorized to act for, any

120

other Lender. The Agents shall have the exclusive right on behalf of the Lenders to enforce the payment of the principal of and interest on any Loan after the date such principal or interest has become due and payable pursuant to the terms of this Agreement.

In their respective capacities, the Agents are “representatives” of the Secured Parties within the meaning of the term “secured party” as defined in the New York Uniform Commercial Code. Each Lender authorizes the Agents to enter into each of the Collateral Documents to which it is a party and to take all action contemplated by such documents. Each Lender agrees that no Secured Party (other than the Agents) shall have the right individually to seek to realize upon the security granted by any Collateral Document, it being understood and agreed that such rights and remedies may be exercised solely by the Agents for the benefit of the Secured Parties upon the terms of the Collateral Documents. In the event that any Collateral is hereafter pledged by any Person as collateral security for the Secured Obligations, the Agents are hereby authorized, and hereby granted a power of attorney, to execute and deliver on behalf of the Secured Parties any Loan Documents necessary or appropriate to grant and perfect a Lien on such Collateral in favor of the Collateral Agent on behalf of the Secured Parties. The Lenders hereby authorize the Collateral Agent to release or, as applicable, subordinate any Lien granted to or held by the Collateral Agent upon any Collateral and to enter into non-disturbance or similar agreements, in each case, in connection with any Indebtedness incurred pursuant to Section 6.01(b)(xvi)(ii) and any other Indebtedness described in Section 9.13, in connection with dispositions of assets permitted under Section 6.02 or, other than with respect to lien release, in connection with licensing or sub-licensing transactions permitted under Sections 6.02 and 6.03, all as described further therein. Upon request by the Collateral Agent at any time, the Lenders will confirm in writing the Collateral Agent’s authority to release or subordinate particular types or items of Collateral and enter into non-disturbance or similar agreements pursuant hereto.

The Administrative Agent and the Collateral Agent are authorized to enter into any Intercreditor Agreement (and any amendments, amendments and restatements, restatements or waivers of or supplements to or other modifications to, and extensions, restructuring, renewals, replacements of, such agreements) in connection with the incurrence by any Loan Party of any Permitted Junior Secured Refinancing Debt, Permitted Pari Passu Secured Refinancing Debt or Permitted Refinancing Indebtedness with respect thereto, or any other Indebtedness permitted by the terms of this Agreement to be secured by the Collateral on apari passu or junior priority secured basis, in each case in order to permit such Indebtedness to be secured by a valid, perfected Lien (with such priority as may be designated by Irish Holdco or relevant Restricted Subsidiary, to the extent such priority is permitted by the Loan Documents), and the parties hereto acknowledge that each Intercreditor Agreement is (if entered into) binding upon them. Each Lender (a) understands, acknowledges and agrees that Liens may be created on the Collateral pursuant to the documentation relating to any Indebtedness incurred as permitted by this Agreement which is (in accordance with the terms hereof) to be secured thereby, on apari passu, or junior, secured basis to the Liens securing the Secured Obligations, which Liens securing any such other Indebtedness shall be subject to the terms and conditions of the relevant Intercreditor Agreement executed and delivered as required hereby, (b) hereby agrees that it will be bound by and will take no actions contrary to the provisions of the respective Intercreditor Agreement (if entered into) and (c) hereby authorizes and instructs the Administrative Agent and Collateral Agent to enter into any Intercreditor Agreement (and any amendments, amendments and restatements, restatements or waivers of or supplements to or other modifications to, such agreements) in connection with the incurrence by any Loan Party of any secured Indebtedness as contemplated above, in order to permit such Indebtedness to be secured by a valid, perfected Lien (with such priority as may be designated by the Borrowers or relevant Restricted Subsidiary, to the extent such priority is permitted by the Loan Documents), and to subject the Liens on the Collateral securing the Secured Obligations to the provisions thereof.

(c)The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. In no event shall the Administrative Agent or any of its Related Parties or any Lead Arranger (collectively, the “Agent Parties”) have any liability to any Loan Party, any Lender, or any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or otherwise) arising out of any Loan Party’s or the Administrative Agent’s transmission of Borrower Materials through the Internet, except to the extent that such losses, claims, damages, liabilities or expenses are determined by a court of competent jurisdiction by a final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Agent Party;provided, however, that in no event shall any Agent Party have any liability to any Loan Party, any Lender or any other Person for indirect, special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

122

(d) Any party hereto may change its address, email address or telephone number for notices and other communications hereunder by notice to the other parties hereto.

Section 9.02Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the Collateral Agent or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Collateral Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 9.02, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, the Collateral Agent or any Lender may have had notice or knowledge of such Default at the time.

(b) Except as provided in Section 2.17 with respect to an Incremental Amendment, Section 2.19 with respect to an Extension Amendment and Section 2.21 with respect to a Refinancing Amendment, neither this Agreement, any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by (A) prior to the Closing Date, Horizon and the Required Lenders or Horizon and the Administrative Agent with the consent of the Required Lenders and (B) from and after the Closing Date, the applicable Borrower and the Required Lenders or by the applicable Borrower and the Administrative Agent with the consent of the Required Lenders;provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon or reduce any fees payable hereunder, without the written consent of each Lender directly affected thereby;provided that only the consent of the Required Lenders shall be necessary to reduce or waive any obligation of the Borrowers to pay interest or fees at the applicable default rate set forth in Section 2.10(c), (iii) postpone the scheduled date of payment of the principal amount of any Loan (other than any reduction of the amount of, or any extension of the payment date for, the mandatory prepayments required under Section 2.08, in each case which shall only require the approval of the Required Lenders), or any interest thereon (other than interest payable at the applicable default rate of interest set forth in Section 2.10(c)), or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender directly affected thereby, (iv) change Section 2.15(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender directly and adversely affected thereby, (v) change any of the provisions of this Section 9.02 or the definitions of “Required Lenders” or “Majority in Interest” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder

123

or make any determination or grant any consent hereunder, without the written consent of each Lender (it being understood that, solely with the consent of the parties prescribed by Section 2.17 or Section 2.21 to be parties to an Incremental Amendment or a Refinancing Amendment, as applicable, Incremental Loans and Other Refinancing Loans may be included in the determination of Required Lenders on substantially the same basis as the Term Loans are included on the Closing Date), (vi) release all or substantially all of the Subsidiary Guarantors from their obligations under the Subsidiary Guaranty without the written consent of each Lender, (vii) except as provided in Section 9.13 or in any Collateral Document, release all or substantially all of the Collateral, without the written consent of each Lender or (viii) change any provisions of any Loan Document in a manner that by its terms adversely affects the rights in respect of payments due to Lenders holding Loans of any Class differently than those holding Loans of any other Class without the written consent of Lenders representing a Majority in Interest of each adversely affected Class;provided,further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Collateral Agent hereunder without the prior written consent of the Administrative Agent or the Collateral Agent, as the case may be.

(c) Notwithstanding the foregoing, this Agreement and any other Loan Document may be amended (or amended and restated) with the written consent of the Required Lenders, the Administrative Agent and the Borrowers (x) to add one or more credit facilities (in addition to the Incremental Term Loans pursuant to an Incremental Amendment and any Credit Agreement Refinancing Indebtedness pursuant to a Refinancing Amendment) to this Agreement and to permit extensions of credit from time to time outstanding thereunder and the accrued interest and fees in respect thereof to share ratably in the benefits of this Agreement and the other Loan Documents with the Term Loans, Incremental Term Loans and the accrued interest and fees in respect thereof and (y) to include appropriately the Lenders holding such credit facilities in any determination of the Required Lenders and Lenders, and for purposes of the relevant provisions of Section 2.15(b).

(d) If, in connection with any proposed amendment, waiver or consent requiring the consent of “each Lender” or “each Lender directly affected thereby,” the consent of the Required Lenders is obtained, but the consent of other necessary Lenders is not obtained (any such Lender whose consent is necessary but not obtained being referred to herein as a “Non-Consenting Lender”), then the Borrowers may elect to replace a Non-Consenting Lender as a Lender party to this Agreement;provided that, concurrently with such replacement, (i) another bank or other entity (which is reasonably satisfactory to the Borrowers and the Administrative Agent) shall agree, as of such date, to purchase for cash the Loans and other Obligations due to the Non-Consenting Lender pursuant to an Assignment and Assumption and to become a Lender for all purposes under this Agreement and to assume all obligations of the Non-Consenting Lender to be terminated as of such date and to comply with the requirements of clause (b) of Section 9.04, and (ii) the Borrowers shall pay to such Non-Consenting Lender in same day funds on the day of such replacement (1) all interest, fees and other amounts then accrued but unpaid to such Non-Consenting Lender by each Borrower hereunder to and including the date of termination, including without limitation payments due to such Non-Consenting Lender under Sections 2.12 and 2.14, (2) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 2.13 had the Loans of such Non-Consenting Lender been prepaid on such date rather than sold to the replacement Lender and (3) any amounts owing to such Lender pursuant to Section 2.09(b). A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

(e) Notwithstanding anything to the contrary herein, (i) if following the date hereof, the Administrative Agent and any Loan Party shall have jointly identified an ambiguity, inconsistency, obvious error or any error or omission of a technical or immaterial nature, in each case, in any provision

124

of the Loan Documents, then the Administrative Agent and Horizon (if prior to the Closing Date) or the Administrative Agent and the applicable Loan Parties (from and after the Closing Date) shall be permitted to amend such provision and such amendment shall become effective without any further action or consent of any other party to any Loan Documents if the same is not objected to in writing by the Required Lenders within five (5) Business Days following receipt of notice thereof and (ii) guarantees, collateral security agreements, pledge agreements and related documents (if any) executed by the Loan Parties in connection with this Agreement may be in a form reasonably determined by the Administrative Agent and may be amended, supplemented and/or waived with the consent of the Administrative Agent at the request of the U.S. Borrower without the input or need to obtain the consent of any other Lenders if such amendment or waiver is delivered in order (x) to comply with local law or advice of local counsel, (y) to cure ambiguities, omissions or defects or (z) to cause such guarantees, collateral security agreements, pledge agreement or other documents to be consistent with this Agreement and the other Loan Documents.

Section 9.03Expenses; Indemnity; Damage Waiver. (a) Prior to the Closing Date, Horizon shall, and hereby agrees to pay and, from and after the Closing Date, Irish Holdco and the Borrowers shall (and hereby jointly and severally agree to) pay (i) all reasonable and documented out-of-pocket expenses incurred by the Agents, the Lead Arrangers and their respective Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agents, in connection with the syndication and distribution (including, without limitation, via the internet or through a service such as Intralinks) of the credit facilities provided for herein, the preparation and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated) and, (ii) all documented out-of-pocket expenses incurred by the Administrative Agent, the Collateral Agent or any Lender, including the reasonable fees, charges and disbursements of any counsel (other than in-house counsel) for the Administrative Agent, the Collateral Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement and any other Loan Document, including its rights under this Section 9.03, or in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans. Notwithstanding the foregoing, in no event shall Horizon, Irish Holdco or the Borrowers be required to reimburse the Lenders for more than one counsel to the Agents (and up to one local counsel in each applicable jurisdiction and regulatory counsel) and one counsel for all of the other Lenders (and up to one local counsel in each applicable jurisdiction and regulatory counsel), unless a Lender or its counsel determines that it would create actual or potential conflicts of interest to not have individual counsel, in which case each Lender may have its own counsel which shall be reimbursed in accordance with the foregoing;provided, that same shall be limited to (A) one counsel to the Administrative Agent and for the Lenders (taken together as a single group or client), (B) if necessary, one local counsel required in any relevant local jurisdiction and applicable special regulatory counsel and (C) if representation of the Administrative Agent and/or all Lenders in such matter by a single counsel would be inappropriate based on the advice of legal counsel due to the existence of an actual or potential conflict of interest, one additional counsel for the Administrative Agent and for each Lender subject to such conflict.

(b) Horizon shall and from and after the Closing Date, Irish Holdco and the Borrowers shall, and jointly and severally agree to, indemnify the Administrative Agent, the Collateral Agent, the Lead Arrangers and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any agreement or instrument contemplated thereby, the performance by the parties hereto of their respective

125

obligations thereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by Irish Holdco or any of its Subsidiaries, or any Environmental Liability related in any way to Irish Holdco or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether (x) any Indemnitee is a party thereto or (y) such matter is initiated by a third party or by Irish Holdco or any of its affiliates;provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or any of its Related Parties, (y) result from a claim brought by any Loan Party against any Indemnitee for a material breach of such Indemnitee’s obligations hereunder or under any other Loan Document (it being understood and agreed that the failure by any Lender to fund any portion of its 2014 Term Loan Commitment hereunder when the conditions set forth in Section 4.02 have been satisfied and/or waived in accordance with this Agreement shall be deemed a material breach, and (z) result from disputes solely among Indemnitees not involving any act or omission of any Loan Party or any of their respective Related Parties (other than a dispute against the Agents or the Lead Arrangers in their capacities as such). Without limiting the provisions of Section 2.14(c), this Section 9.03(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. from a non-Tax claim.

(c) To the extent that Irish Holdco, Horizon or any Borrower fails to pay any amount required to be paid by it to the Administrative Agent or the Collateral Agent under paragraph (a) or (b) of this Section 9.03, each Lender severally agrees to pay to the Administrative Agent or the Collateral Agent, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount (it being understood that any Borrower’s failure to pay any such amount shall not relieve such Borrower of any default in the payment thereof);provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Collateral Agent in its capacity as such.

(d) To the extent permitted by applicable law, neither Irish Holdco, Horizon nor any Borrower shall assert, and each hereby waives, any claim against any Indemnitee (i) for any damages arising from the use by others of information or other materials obtained through telecommunications, electronic or other information transmission systems (including the Internet) other than damages that are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or any of its Related Parties, or (ii) on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or the use of the proceeds thereof.

(e) All amounts due under this Section 9.03 shall be payable not later than fifteen (15) days after written demand therefor.

Section 9.04Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) neither Irish Holdco, Horizon nor either of the Borrowers may assign or otherwise transfer any of their rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by Irish Holdco, Horizon or any of the Borrowers without such

126

consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except to an Eligible Transferee. 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, Participants (to the extent provided in paragraph (c) of this Section 9.04) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees (other than (x) Irish Holdco and its Affiliates, except to the extent permitted in Section 2.20 and (y) any Person that is not an Eligible Transferee) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with the prior written consent of:

(A) For assignments prior to the Closing Date, Horizon (such consent not to be unreasonably withheld);

(B) For assignments from and after the Closing Date, any applicable Borrower (such consent not to be unreasonably withheld);provided that any such Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within ten (10) Business Days after having received written notice thereof;provided,further, that no consent of the applicable Borrowers shall be required for (x) any assignment by any Agent, Lead Arranger (or any affiliate thereof) of Term Loans or related commitments pursuant to the primary syndication of such Term Loans and related commitments or (y) an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default under clause (a), (b), (h), (i) or (j) of Article VII has occurred and is continuing, any other assignee; and

(C) the Administrative Agent (such consent not to be unreasonably withheld);provided that no consent of the Administrative Agent shall be required for an assignment of all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the applicable Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $1,000,000 unless each of the applicable Borrower and the Administrative Agent otherwise consent;provided that no such consent of the applicable Borrower shall be required if an Event of Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Commitments or Loans;

127

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, such fee to be paid by either the assigning Lender or the assignee Lender or shared between such Lenders, and which fee may be waived at the discretion of the Administrative Agent;

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the assignee designates one or more credit contacts to whom all syndicate-level information (which may contain material non-public information about Irish Holdco and its affiliates and their Related Parties or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws;

(E) without the prior written consent of the Administrative Agent, no assignment shall be made to a prospective assignee that bears a relationship to the applicable Borrowers as described in Section 108(e)(4) of the Code; and

(F) if, at the time of any assignment, the respective assignee would be entitled to greater increased cost payments pursuant to Section 2.12 than those that apply to the respective assignor, then the respective assignee shall not be entitled to charge the Borrowers for any such increased costs which would otherwise be owed to it pursuant to Section 2.12, but in each case only to the extent in excess of those that would have applied to the respective assignor at the time of such assignment.

For the purposes of this Section 9.04(b), the term “Approved Fund” has the following meaning:

“Approved Fund” means any Person (other than a natural person) that is (or will be) engaged in making, purchasing, holding or investing in commercial loans and similar extensions of credit in the ordinary course of its business and that is administered, advised or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section 9.04, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section 9.04.

(iv) The Administrative Agent, acting for this purpose as a non-fiduciary agent of the Borrowers, shall maintain at one of its offices located in the United States a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of and interest on the

128

Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive (absent manifest error), and the Borrowers, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes, notwithstanding notice to the contrary. The Register shall be available for inspection by each Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section 9.04 and any written consent to such assignment required by paragraph (b) of this Section 9.04, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register;provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.04(b), 2.15(d) or 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c) (i) Any Lender may, without the consent of the applicable Borrowers or the Administrative Agent, sell participations to one or more banks or other entities (excluding (x) Irish Holdco and its Affiliates and (y) any Person that is not an Eligible Transferee) (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it);provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (C) Irish Holdco, Horizon, the Borrowers, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (D) without the prior written consent of the Administrative Agent, no participation shall be sold to a prospective participant that bears a relationship to the applicable Borrowers described in Section 108(e)(4) of the Code. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement;provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section 9.04, each of the Borrowers agrees that each Participant shall be entitled to the benefits of Sections 2.12, 2.13 and 2.14 (subject to the requirements and limitations therein including the requirements under Section 2.14(e)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 9.04. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender;provided such Participant agrees to be subject to Section 2.15(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.12 or 2.14 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with any applicable Borrower’s prior written consent or such right to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable

129

participation. A Participant shall not be entitled to the benefits of Section 2.14 unless the applicable Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of such Borrower, to comply with Section 2.14(e), Section 2.14(h) and Section 2.16 as though it were a Lender (it being understood that the documentation required under Section 2.14(e) shall be delivered to the participating Lender and the documentation required under Section 2.14(h) and the documentation required for the purposes of satisfying the procedural formalities referred to in paragraph (5) of the definition of Irish Qualifying Lender (if required) shall be delivered to the Administrative Agent and the applicable Borrower). Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the applicable Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”);provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations and/or Irish law to the extent necessary to claim exemption from applicable Irish tax. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central bank, and this Section 9.04 shall not apply to any such pledge or assignment of a security interest;provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(e) In the case of any assignment or transfer by a Lender to a new Lender, or any participation by such Lender in favor of a Participant, of all or any part of such Lender’s rights and obligations under this Agreement or any of the other Loan Documents, such Lender and the new Lender or Participant (as applicable) hereby agree that, for the purposes of Article 1278 and/or Article 1281 of the Luxembourg Civil Code (to the extent applicable), any assignment, amendment and/or transfer of any kind permitted under, and made in accordance with the provisions of, this Agreement or any agreement referred to herein to which Luxco is a party (including any Collateral Document), any security created or guarantee given under or in connection with this Agreement or any other Loan Document shall be preserved and shall continue in full force and effect for the benefit of such new Lender or Participant (as applicable).

Section 9.05Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall

130

continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement or any other Loan Document is outstanding and unpaid (except for Unliquidated Obligations) and so long as the Commitments have not expired or terminated. The provisions of Sections 2.12, 2.13, 2.14 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans and the Commitments or the termination of this Agreement or any other Loan Document or any provision hereof or thereof.

Section 9.06Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Agents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective upon the delivery by the Agents, the Lenders and Horizon of executed counterparts of the signature page to this Agreement. For the avoidance of doubt, upon the effectiveness of this Agreement, the 2014 Term Loan Commitments shall become enforceable by Horizon. Each of Irish Holdco, Irish Intermediate Holdco, Irish New Intermediate Holdco and the Borrowers shall become parties to this Agreement after the effectiveness thereof by delivery of an executed joinder agreement substantially in the form of Exhibit D or in such other form reasonably acceptable to such Person and the Administrative Agent (each a “Joinder Agreement”) on or prior to the Closing Date. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or by email as a “.pdf” or “.tif” attachment shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 9.07Severability. Any provision of any Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 9.08Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final and in whatever currency denominated) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrowers or any Subsidiary Guarantor against any of and all of the Secured Obligations held by such Lender, irrespective of whether or not such Lender shall have made any demand under the Loan Documents and although such obligations may be unmatured; provided that any recovery by any Lender or any Affiliate pursuant to its setoff rights under this Section 9.08 is subject to the provisions of Section 2.15(c). The rights of each Lender under this Section 9.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Section 9.09Governing Law; Jurisdiction; Consent to Service of Process; Foreign Process Agent. (a) This Agreement and each other Loan Document (except, as to any other Loan Document, as expressly set forth therein) shall be construed in accordance with and governed by the law of the State of New York; provided, however, that (i) the interpretation of the definition of “Target Material Adverse Effect” and whether there shall have occurred a “Target Material Adverse Effect”, (ii) whether the Acquisition has been consummated in accordance with the terms and conditions of the Acquisition Agreement, and (iii) whether the representations and warranties made by Vidara Holdings and its subsidiaries in the Acquisition Agreement are true and correct and whether as a result of any failure thereof Horizon has the right to terminate its obligations under the Acquisition Agreement (or the right

131

not to consummate the Acquisition pursuant to the Acquisition Agreement) shall be determined in accordance with the laws of the State of Delaware without regards to conflicts of laws principles that would result in the application of the laws of another jurisdiction.

(b) Irish Holdco, Irish Intermediate Holdco, Irish New Intermediate Holdco, Horizon and each of the Borrowers hereby irrevocably and unconditionally submit, for themselves and their property, to the exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against any Loan Party or its properties in the courts of any jurisdiction.

(c) Irish Holdco, Irish Intermediate Holdco, Irish New Intermediate Holdco, Horizon and each of the Borrowers hereby irrevocably and unconditionally waive, to the fullest extent they may legally and effectively do so, any objection which they may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section 9.09. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

(b) Upon the termination of all the Commitments and payment and satisfaction in full in cash of all Secured Obligations (other than Unliquidated Obligations for which no claim has been made), the security interests in the Collateral created by the Collateral Documents shall be automatically released.

Any execution and delivery of documents pursuant to this Section 9.13 shall be without recourse to or warranty by the Collateral Agent.

Section 9.14USA PATRIOT Act. Each Lender that is subject to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “USA Patriot Act”) hereby notifies each Loan Party that pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies such Loan Party, which information includes the

134

name and address of such Loan Party and other information that will allow such Lender to identify such Loan Party in accordance with the USA Patriot Act.

To the fullest extent permitted by law, Irish Holdco, Horizon and the Borrowers hereby waive and release any claims that they may have against each of the Lenders and their Affiliates with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

Section 9.17Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the applicable Borrowers. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

Section 10.01Irish Holdco, Irish Intermediate Holdco and Borrower Guaranty. (a) Each of Irish Holdco, Irish Intermediate Holdco and each Borrower hereby jointly and severally guarantees to each Secured Party as hereinafter provided, as primary obligor and not as surety, the payment of the Secured Obligations in full in cash when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) strictly in accordance with the terms thereof. Irish Holdco, Irish Intermediate Holdco and each Borrower hereby further jointly and severally agrees that if any of the Secured Obligations are not paid in full in cash when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise), Irish Holdco, Irish Intermediate Holdco and each Borrower will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Secured Obligations, the same will be promptly paid in full in cash when due (whether at extended maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) in accordance with the terms of such extension or renewal.

(b) Each Guarantor, and by its acceptance of this Guaranty, the Administrative Agent and each other Secured Party, hereby confirms that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of any Debtor Relief Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the Obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the other Secured Parties and the Guarantors hereby irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance under applicable law after giving full effect to such Guarantor’s contribution rights but before taking into account any liabilities of such Guarantor under any other guarantee of such Guarantor other than any other guarantee of any obligations that are secured on a pari passu basis with the Obligations.

Section 10.02Obligations Unconditional. (a) The obligations of Irish Holdco, Irish Intermediate Holdco and each Borrower under Section 10.01 are absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of any of the Loan Documents or other documents relating to the Secured Obligations, or any substitution, release, impairment or exchange of any other guarantee of or security for any of the Secured Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor (other than payment in full in cash of the Secured Obligations, other than Unliquidated Obligations for which no claim has been made), it being the intent of this Section 10.02 that the obligations of Irish Holdco, Irish Intermediate Holdco and each Borrower hereunder shall be absolute and unconditional under any and all circumstances. Each of Irish Holdco, Irish Intermediate Holdco and each Borrower agree that they shall have no right of subrogation, indemnity, reimbursement or contribution against a Borrower or any other Guarantor for amounts paid under this Article X until such time as the Secured Obligations (other than Unliquidated Obligations for which no claim has been made) have been paid in full in cash and the Commitments have expired or terminated.

(b) Without limiting the generality of the foregoing, it is agreed that, to the fullest extent permitted by law, the occurrence of any one or more of the following shall not alter or impair the

136

liability of Irish Holdco, Irish Intermediate Holdco or any Borrower hereunder, which shall remain absolute and unconditional as described above:

(i) at any time or from time to time, without notice to Irish Holdco, Irish Intermediate Holdco or any Borrower, the time for any performance of or compliance with any of the Secured Obligations shall be extended, or such performance or compliance shall be waived;

(ii) any of the acts mentioned in any of the provisions of any of the Loan Documents or other documents relating to the Secured Obligations shall be done or omitted;

(iii) the maturity of any of the Secured Obligations shall be accelerated, or any of the Secured Obligations shall be modified, supplemented or amended in any respect, or any right under any of the Loan Documents or other documents relating to the Secured Obligations shall be waived or any other guarantee of any of the Secured Obligations or any security therefor shall be released, impaired or exchanged in whole or in part or otherwise dealt with;

(iv) any Lien granted to, or in favor of, the Administrative Agent, the Collateral Agent or any other holder of the Secured Obligations as security for any of the Secured Obligations shall fail to attach or be perfected; or

(v) any of the Secured Obligations shall be determined to be void or voidable (including, without limitation, for the benefit of any creditor of Irish Holdco or Irish Intermediate Holdco) or shall be subordinated to the claims of any Person (including, without limitation, any creditor of Irish Holdco or Irish Intermediate Holdco).

(c) With respect to its obligations hereunder, each of Irish Holdco, Irish Intermediate Holdco and each Borrower hereby expressly waive diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Administrative Agent, the Collateral Agent or any other holder of the Secured Obligations exhaust any right, power or remedy or proceed against any Person under any of the Loan Documents or other documents relating to the Secured Obligations, or against any other Person under any other guarantee of, or security for, any of the Secured Obligations.

Section 10.03Reinstatement. The obligations of Irish Holdco, Irish Intermediate Holdco and each Borrower under this Article X shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Person in respect of the Secured Obligations is rescinded or must be otherwise restored by any holder of any of the Secured Obligations, whether as a result of any proceedings under any Debtor Relief Law, and each of Irish Holdco, Irish Intermediate Holdco and each Borrower agree that they will jointly and severally indemnify the Administrative Agent and each holder of the Secured Obligations on demand for all reasonable costs and expenses (including, without limitation, the fees, charges and disbursements of counsel) incurred by the Administrative Agent or such holder of the Secured Obligations in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any proceedings under any debtor relief law.

Section 10.04Certain Additional Waivers. Each of Irish Holdco, Irish Intermediate Holdco and each Borrower further agree that they shall have no right of recourse to security for the Secured

137

Obligations, except through the exercise of rights of subrogation pursuant to Section 10.02 and through the exercise of rights of contribution pursuant to Section 10.06.

Section 10.05Remedies. Each of Irish Holdco, Irish Intermediate Holdco and each Borrower agree that, to the fullest extent permitted by law, as between Irish Holdco, Irish Intermediate Holdco and each Borrower, on the one hand, and the Administrative Agent, the Collateral Agent and the other holders of the Secured Obligations, on the other hand, the Secured Obligations may be declared to be forthwith due and payable as provided in Article VII (and shall be deemed to have become automatically due and payable in the circumstances provided in said Article VII) for purposes of Section 10.01 notwithstanding any stay, injunction or other prohibition preventing such declaration (or preventing the Secured Obligations from becoming automatically due and payable) as against any other Person and that, in the event of such declaration (or the Secured Obligations being deemed to have become automatically due and payable), the Secured Obligations (whether or not due and payable by any other Person) shall forthwith become due and payable by Irish Holdco, Irish Intermediate Holdco and each Borrower for purposes of Section 10.01. Each of Irish Holdco, Irish Intermediate Holdco and each Borrower acknowledge and agree that their respective obligations hereunder are secured in accordance with the terms of the Collateral Documents and that the holders of the Secured Obligations may exercise their remedies thereunder in accordance with the terms thereof.

Section 10.06Rights of Contribution. Each of Irish Holdco, Irish Intermediate Holdco and the Borrowers agree that, in connection with payments made hereunder, Irish Holdco, Irish Intermediate Holdco, the Borrowers and each other Guarantor shall have contribution rights against the other Guarantors as permitted under applicable law. Such contribution rights shall be subordinate and subject in right of payment to the obligations of such Guarantors under the Loan Documents and no Guarantor shall exercise such rights of contribution until all Secured Obligations (other than Unliquidated Obligations for which no claim has been made) have been paid in full in cash and the Commitments have terminated.

Section 10.07Guarantee of Payment; Continuing Guarantee. The guarantee given by Irish Holdco, Irish Intermediate Holdco and each Borrower in this Article X is a guaranty of payment and not of collection, is a continuing guarantee, and shall apply to all Secured Obligations whenever arising.

Section 10.08Guarantee Limitations. Notwithstanding anything to the contrary contained in this Agreement or in any other Loan Documents, the guarantee obligations of each of Luxco and any other Guarantor established in Luxembourg (a “Luxembourg Guarantor”) in respect of the obligations of Irish Holdco or any of its Subsidiaries which is not a direct or indirect subsidiary of such relevant Luxembourg Guarantor shall be limited at any time to an aggregate amount not exceeding 95% of the greater of:

(a) the Luxembourg Guarantor’s own funds (capitaux propres), as referred to in article 34 of the Luxembourg Law dated 19 December 2002 concerning the trade and companies register and the accounting and annual accounts of undertakings, as amended (the “2002 Law”), increased by the amount of any debts owed to a company of the same group of the Luxembourg Guarantor, as shown in (x) the latest interim financial statements available (if any), at the date of demand of payment under this Agreement or, if not available, (y) the latest annual financial statements (comptes annuels) available at the date of demand of payment under this Agreement; and

(b) the Luxembourg Guarantor’s own funds (capitaux propres), as referred to in article 34 of the 2002 Law, increased by the amount of any debts owed to a company of the same group of the Guarantor, at the date of entry into this Agreement.

138

The limitation set forth under items (i) and (ii) above shall not apply to any amounts borrowed under this Agreement and made available, in any form whatsoever, to the Luxembourg Guarantor or any of its direct or indirect subsidiaries.

SCHEDULE 1.01A

AGREED SECURITY PRINCIPLES

Unless otherwise defined herein, capitalized terms used herein and defined in the Agreement to which this Schedule 1.01A is attached are used herein as therein defined.

(A)	Considerations

1.	In determining what Liens will be granted by Foreign Loan Parties or in respect of Foreign Assets to secure the Secured Obligations the following matters will be taken into account. Liens shall not be created or perfected to the extent that they would:

(a)

result in any breach of corporate benefit, financial assistance, related or connected person transaction, fraudulent preference, thin capitalisation laws, capital maintenance rules or the laws or regulations (or analogous restrictions) of any applicable jurisdiction or any similar principles which may limit the ability of any Foreign Loan Party to provide a guarantee or security or may require that that the guarantee or security be limited by an amount or otherwise;

(b)

result in any (x) material risk to the officers of the relevant grantor of Liens of contravention of their fiduciary duties and/or (y) risk to the officers of the relevant grantor of Liens of civil or criminal liability (in each case, other than arising from fraud, gross negligence or wilful misconduct of the relevant officer);

(c)

result in costs that are disproportionate to the benefit obtained by the beneficiaries of the Liens by reference to the costs of creating or perfecting the lien versus the value of the assets being secured;

(d)

impose an undue administration burden on, or material inconvenience to the ordinary course of operations of, the provider of the Lien, in each case which is disproportionate to the benefit obtained by the beneficiary of the Lien; or

(e)

create Liens over any assets subject to third party arrangements which are permitted by the Loan Documents to the extent (and for so long as) such arrangements prevent those assets from being charged.

These Agreed Security Principles embody recognition by all parties that there may be certain legal, regulatory and practical difficulties (including those in paragraph 1 above) in obtaining security from all Foreign Loan Parties or Foreign Assets in every jurisdiction in which Foreign Loan Parties or Foreign Assets are located, in particular:

(a)

perfection of liens, when required, and other legal formalities will be completed as soon as practicable and, in any event, within the time periods specified in the Loan Documents or (if earlier or to the extent no such time periods are specified in the Loan Documents) within the time periods specified by applicable law in order to ensure due perfection. Perfection of security will not be required if it would have a material adverse effect on the ability of the relevant Foreign Loan Party to conduct its operations and business in the ordinary course as otherwise permitted by the Loan Documents;

(b)

the maximum granted or secured amount may be limited to minimise stamp duty, notarisation, registration or other applicable fees, taxes and duties where the benefit of increasing the granted or secured amount is disproportionate to the level of such fees, taxes and duties; or

(c)

where a class of assets to be secured includes material and immaterial assets, if the costs of granting security over the immaterial assets is disproportionate to the benefit of such security, security will be granted over the material assets only.

For the avoidance of doubt, in these Agreed Security Principles, “cost” includes, but is not limited to, income tax cost, registration taxes payable on the creation or enforcement or for the continuance of any Liens, stamp duties, the cost of maintaining capital for regulatory purposes,out-of-pocket expenses, and other fees and expenses directly incurred by the relevant grantor of Liens or any of its direct or indirect owners, subsidiaries or Affiliates.

(B)	Obligations to be Guaranteed and Secured

Subject to paragraph (A) above and to paragraph (B)2 below, the obligations to be secured are the Secured Obligations. The Liens are to be granted in favor of the Administrative Agent or Collateral Agent on behalf of each Secured Party (or equivalent local procedure and unless otherwise necessary in any jurisdictions). Subject to paragraph (B)2 below, the obligations to be guaranteed by Foreign Loan Parties are the Secured Obligations.

For ease of reference, the definitions of the “Secured Obligations” and “Secured Parties” set forth in the Agreement should, where relevant and to the extent legally possible, be incorporated into each Collateral Document (with the capitalised terms used in them having the meaning given to them in this Agreement).

2.	The Secured Obligations may be limited pursuant to the terms of the relevant Collateral Document and the Secured Obligations may be limited pursuant to the terms of the Subsidiary Guaranty:

2.1	to avoid any breach of corporate benefit, financial assistance, fraudulent preference, related or connected person transaction, thin capitalisation rules or the laws or regulations (or analogous restrictions) of any applicable jurisdiction; and

2.2

to avoid any (x) material risk to officers of the relevant party that is granting Liens in contravention of their fiduciary duties and/or (y) risk to the officers of the relevant grantor of Liens of civil or criminal or personal liability (in each case, other than arising from fraud, gross negligence or wilful misconduct of the relevant officer).

(C)	General

1.	Where appropriate, defined terms in the Collateral Documents should mirror those in this Agreement and the U.S. Security Agreement, as applicable.

The parties to this Agreement agree to negotiate the form of each Collateral Document in good faith. The form of guarantee is the Subsidiary Guaranty and, with respect to any Foreign Loan Party, shall be subject to any limitations as set out in the joinder, supplement or other Guaranty applicable to such Foreign Loan Party as may be required in order to comply with local laws and practice in accordance with these Agreed Security Principles.

The Liens granted by any Foreign Loan Party in favor of the Administrative Agent or Collateral Agent on behalf of each Secured Party shall, to the extent possible under local law, be enforceable upon the acceleration of any of the Obligations under the Agreement pursuant to Article VII thereof (an “Enforcement Event”).

(D)	Covenants/Representations and Warranties

Any representations, warranties or covenant which are required to be included in any Collateral Document shall reflect (to the extent to which the subject matter of such representation, warranty and covenant is the same as the corresponding representation, warranty and undertaking in this Agreement) the commercial deal set out in this Agreement and the U.S. Security Agreement (except to the extent that the Administrative Agent’s or Collateral Agent’s, as applicable, local counsel advise it necessary to include any further provisions (or deviate from those contained in this Agreement or the U.S. Security Agreement) in order to protect or preserve the Liens granted to the Administrative Agent or Collateral Agent on behalf of each Secured Party). Accordingly, the Collateral Documents shall not include, repeat or extend clauses set out in the Agreement including the representations or undertakings in respect of insurance, maintenance of assets, information, indemnities or the payment of costs or impose additional negative covenants, in each case, unless applicable local counsel advise it necessary in order to ensure the validity of any Collateral Document or the perfection of any Lien granted thereunder.

(E)	Liens over Land and Buildings

Subject to (A) and (B) above, any mortgage over (x) real estate owned by a Foreign Loan Party with a fair market value of more than $5,000,000 or (y) real estate leased by a Foreign Loan Party that is material to the business of such Loan Party and subject to a lease with an unexpired term in excess of 90 years will, in each case, charge land and interests in land and buildings, except where granting the Lien would contravene any legal or contractual prohibition, in which case, the proposed grantor of such Lien will use commercially reasonable efforts to remove the prohibition or obtain any required consent prior to the date the relevant Collateral Document is required to be granted.

2.	There will be no obligations to investigate title, provide surveys or other insurance or environmental due diligence other than to the extent customary under relevant local practice.

(F)	Liens over Equity Interests

1.	Subject to (A), (B) and (C) above, equitable share charges (or the equivalent in local jurisdictions) will be made over Equity Interests in Foreign Loan Parties that are Material Subsidiaries in accordance with Section 5.09.

Subject to (A), (B) and (C) above, any equitable share charges (or the equivalent in local jurisdictions) over Equity Interests in Loan Parties will be granted pursuant to which the Administrative Agent or Collateral Agent on behalf of each Secured Party will be entitled, subject to local laws, to transfer the Equity Interests and satisfy themselves out of the proceeds of such sale upon enforcement of the Lien.

Subject to (A), (B) and (C) above, to the extent permitted under local law, share pledges should contain provisions to ensure that, unless an Enforcement Event has occurred and is continuing, the grantor of the Lien is entitled to receive dividends and exercise voting rights in any shareholders’ meeting of the relevant company (except if exercise would be materially adverse to

the validity or enforceability of the Lien created or would materially impair the value of the shares charged) and if an Enforcement Event has occurred and is continuing the voting and dividend receipt rights may only be exercised by the Administrative Agent or Collateral Agent, as applicable, on behalf of each Secured Party, it being understood that if such Enforcement Event is subsequently remedied or waived, the right to receive dividends and the voting rights in any shareholders’ meeting of the relevant company shall return to the grantor of the Lien.

4.	Liens over Equity Interests will, where possible, automatically charge further Equity Interests issued or otherwise contemplate a procedure for the extension (at the cost of the relevant Loan Party) of Liens over newly-issued shares.

5.	Liens will not be created over minority shareholdings or Equity Interests in joint ventures where the consent of a third party is required before the relevant Loan Party can create a Lien over the same unless such consent has been obtained.

6.	Liens will not be created on Equity Interests so long as same constitute Margin Stock.

(G)	Liens over Receivables of Foreign Loan Parties

Except where an Enforcement Event has occurred and is continuing, unless necessary to ensure the creation of valid and/or perfected security, (and notwithstanding that the Lien may be expressed as a first fixed charge) the proceeds of Receivables shall not be paid into a nominated account unless the relevant Foreign Loan Party is able freely to withdraw such money and the Foreign Loan Party shall be free to deal with those receivables in the course of its business.

Each relevant Foreign Loan Party shall not be required to notify third party debtors to any contracts that have been assigned and/or charged under a Collateral Document unless (i) so required by the Administrative Agent or Collateral Agent if an Enforcement Event has occurred and is continuing or (ii) otherwise customary under relevant local practice and is not materially prejudicial to the business relationship of such Foreign Loan Party. The Administrative Agent or Collateral Agent, as applicable, shall however be entitled to give such notice if an Enforcement Event has occurred and is continuing.

3.	No Lien will be granted under local law over any Receivables to the extent (and for so long as) such Receivable cannot be secured under the terms of the relevant contract.

(H)	Insurances

Subject to (A), (B) and (C) above, proceeds of material insurance policies owned by each relevant Foreign Loan Party (excluding third party liability insurance policies) are to be assigned by way of security or pledged to the Administrative Agent or Collateral Agent, as applicable, on behalf of each Secured Party. Proceeds of insurance shall be collected and retained by the relevant Foreign Loan Party (without the further consent of the Secured Parties) (i) unless such insurance proceeds must be applied to mandatory prepayment in accordance with Section 2.08(b)(i) of this Agreement or (ii) unless an Enforcement Event has occurred and is continuing.

If required by local law to create or perfect the security, notice of the security will be served on the insurance provider within 10 Business Days of the security being granted and, to the extent so required, the Foreign Loan Party shall use its reasonable endeavours to obtain an acknowledgement of that notice within 30 Business Days of service. If a Foreign Loan Party has

used its reasonable endeavours but has not been able to obtain acknowledgement its obligations to obtain acknowledgement shall cease on the expiry of that 30 Business Days period.

(I)	Material Contracts And Claims

No Foreign Loan Party shall be required to notify the counterparties to any contracts that have been charged/assigned under a Collateral Document that such contract has been so charged/assigned unless (i) required by the Administrative Agent or Collateral Agent, as applicable, if an Enforcement Event has occurred and is continuing or (ii) otherwise customary under relevant local practice and is not materially prejudicial to the business relationship of such Foreign Loan Party. Liens should not be created over contracts, leases or licenses which prohibit assignment or the creation of such Liens or which require the consent of third parties for the creation of such Liens or such assignment unless the contracts are material and such consent has been obtained.

Proceeds of material contracts and claims shall be collected and retained by the relevant Foreign Loan Party (without the further consent of the Secured Parties) (i) unless such proceeds must be applied to mandatory prepayment in accordance with Section 2.08(b)(i) of this Agreement or (ii) unless an Enforcement Event has occurred and is continuing.

(J)	Liens Over Foreign Intellectual Property

Subject to (A) and (B) above, Liens over all registered Foreign Intellectual Property (other than any applications for trademarks or service marks filed in the United States Patent and Trademark Office (“PTO”), or any successor office thereto pursuant to 15 U.S.C. §1051 Section 1(b) unless and until evidence of use of the mark in interstate commerce is submitted to the PTO pursuant to 15 U.S.C. §1051 Section 1(c) or Section 1(d)) owned by each relevant Loan Party are to be given, and registration is to be made in all relevant registries of a Covered Jurisdiction in which the grantor of the Liens is resident or carries on material business (in each case to the extent such Foreign Intellectual Property is registered in such jurisdiction) unless the granting of such Liens would contravene any legal or contractual prohibition. Where any relevant Loan Party has the right to the use of any Foreign Intellectual Property through contractual arrangements to which it is a party, a Lien over such contract and/or any rights arising thereunder shall be given in favor of the Administrative Agent or Collateral Agent on behalf of each Secured Party, except to the extent (and for so long as) the giving over of such Liens would contravene any legal or contractual prohibition. Notwithstanding anything to the contrary herein, Liens should not be created over intellectual property or any contractual relationships described above (or any rights arising thereunder) where such Lien or assignment is prohibited or the consent of third parties would be required for the creation of such Lien or such assignment unless such consent has been obtained. Liens over intellectual property will only be required to be perfected in the United States of America, except with respect to Foreign Intellectual Property issued or registered by, or applied-for in a Covered Jurisdiction. “Covered Jurisdiction” means the jurisdiction of organization of the applicable Grantor, the United States, the United Kingdom, European Patent Office, Germany and any other EU jurisdiction to the extent revenues derived from such jurisdiction exceed 5% or more of the aggregate revenues of Irish Holdco and its Subsidiaries (after giving effect to the Transactions).

If a Foreign Loan Party grants a Lien over any of its intellectual property, it will be free to deal with those assets in the course of its business (including without limitation, allowing any intellectual property to lapse or become abandoned if, in the reasonable good faith judgment of Irish Holdco, it is no longer useful, valuable, or material to the conduct of the business of Irish

Holdco and its Subsidiaries, taken as a whole) until an Enforcement Event has occurred and is continuing.

(K)	Liens Over Bank Accounts

If customary for the applicable jurisdiction, where any Foreign Loan Party is granting a Lien over a bank account it shall, at the request of the Collateral Agent, notify the relevant bank of, and shall use commercially reasonable efforts to procure that the relevant bank acknowledges the creation of that Lien. Such Foreign Loan Party shall be free to deal with those accounts in the course of its business until an Event of Default has occurred and is continuing.

If required by local law to perfect the security and/or to give effect to the making thereof, notice of the security will be served on the account bank within 5 Business Days of the security being granted and, to the extent so required, the Foreign Loan Party shall use its reasonable endeavours to obtain an acknowledgement of that notice within 30 Business Days of service. If the Foreign Loan Party has used its reasonable endeavours but has not been able to obtain acknowledgement, its obligation to obtain acknowledgement shall cease on the expiry of that 30 Business Day period. Irrespective of whether notice of the security is required for perfection, if the service of notice would prevent the Foreign Loan Party from using a bank account in the course of its business, no notice of security shall be served until an Event of Default has occurred and is continuing.

Any security over bank accounts shall be subject to any prior security interests in favour of the account bank which are created either by law or in the standard terms and conditions of the account bank. The notice of security shall request these are waived by the account bank but the Foreign Loan Party shall not be required to change its banking arrangements if these security interests are not waived or only partially waived.

Notwithstanding the foregoing, the provisions of this Section (K) shall not apply to Excluded Accounts. For the avoidance of doubt, no control agreements shall be required with respect to the perfection of any security interest or Lien in any Deposit Accounts or Securities Accounts (in each case, as defined in the UCC).

(L)	Other Assets

Liens shall be given over any other material assets of any relevant Foreign Loan Party from time to time, according to the principles set out herein. Such Foreign Loan Party shall be free to deal with those assets in the course of its business until an Enforcement Event has occurred and is continuing.

2.	To the extent any Loan Party owns any Foreign Assets that are located in a jurisdiction other than a Covered Jurisdiction, no action under the laws of such jurisdiction shall be required to grant or perfect Liens in such Foreign Assets.

(M)	Perfection of Liens

Where customary, a Collateral Document may contain a power of attorney allowing the Administrative Agent or the Collateral Agent, as applicable, to perform on behalf of the grantor of the Lien, its obligations under such Collateral Document only if an Enforcement Event has occurred and is continuing.

Subject to (A) and (B) above, where obligatory or customary under the relevant local law all registrations and filings necessary in relation to the Collateral Documents and/or the Liens evidenced or created thereby are to be undertaken within applicable time limits, by the appropriate local counsel (based on local law and custom), unless otherwise agreed.

3.	Subject to (A) and (B) above, where obligatory or customary, documents of title relating to the assets charged will be required to be delivered to the Administrative Agent or the Collateral Agent, as applicable.

Except as explicitly provided herein, notice, acknowledgement or consent to be obtained from a third party will only be required where the efficacy of the Lien requires it or where it is practicable and reasonable having regard to the costs involved, the commercial impact on the Foreign Loan Party in question and the likelihood of obtaining the acknowledgement and, when possible without prejudicing the validity of the Lien concerned, such perfecting procedures shall be delayed until an Enforcement Event has occurred and is continuing.

(N)

Liens

Notwithstanding anything to the contrary contained in this agreement, no provision contained herein shall prejudice the right of the Loan Parties to benefit from the permitted exceptions set out in Section 6.02 of this Agreement regarding the granting of Liens over assets.

(O)	Proceeds

The Collateral Documents will state that the proceeds of enforcement of such Collateral Document will be applied as specified in Section 2.15(b) of this Agreement.

(P)	Regulatory consent

The enforcement of security over shares and the exercise by the Administrative Agent or the Collateral Agent, as applicable, of voting rights in respect of such shares may be subject to regulatory consent. Accordingly, enforcement of any security over any shares subject to such a restriction, and the exercise by the Administrative Agent or the Collateral Agent, as applicable, of the voting rights in respect of any such shares, will be expressed to be conditional upon obtaining any consents required by law or regulation.

EXHIBIT B

AUCTION PROCEDURES

ThisExhibit B is intended to summarize certain basic terms of the modified Dutch auction (an “Auction”) procedures pursuant to and in accordance with the terms and conditions ofSection 2.20 of that certain Agreement of which thisExhibit B is a part (as amended, restated, amended and restated, supplemented and otherwise modified from time to time, the “Credit Agreement”). It is not intended to be a definitive statement of all of the terms and conditions of an Auction, the definitive terms and conditions for which shall be set forth in the applicable offering document. None of the Administrative Agent, the Auction Manager, or any of their respective affiliates or any officers, directors, employees, agents or attorneys-in-fact of such Persons (together with the Administrative Agent and its affiliates, the “Agent-Related Person”) makes any recommendation pursuant to any offering document as to whether or not any Lender should sell its Term Loans to any of the Borrowers pursuant to any offering documents, nor shall the decision by the Administrative Agent, the Auction Manager or any other Agent-Related Person (or any of their affiliates) in its respective capacity as a Lender to sell its Term Loans to any of the Borrowers be deemed to constitute such a recommendation. Each Lender should make its own decision on whether to sell any of its Term Loans and, if it decides to do so, the principal amount of and price to be sought for such Term Loans. In addition, each Lender should consult its own attorney, business advisor or tax advisor as to legal, business, tax and related matters concerning each Auction and the relevant offering documents. Capitalized terms not otherwise defined in thisExhibit B have the meanings assigned to them in the Credit Agreement.

ANY PURCHASE OF TERM LOANS MADE UNDER SUCH AUCTIONS SHALL NOT BE SUBJECT TO THE CALL PROTECTION PROVISIONS IN SECTION 2.09(b) OF THE CREDIT AGREEMENT.

1.Notice Procedures. In connection with each Auction, the applicable Borrower will provide notification to the Auction Manager (for distribution to the Term Lenders of the applicable Class of Term Loans (each, an “Auction Notice”). Each Auction Notice shall contain (i) the maximum principal amount (calculated on the face amount thereof) of Term Loans of each applicable Class that the applicable Borrower offers to purchase in such Auction (the “Auction Amount”) which shall be no less than $10,000,000 (unless another amount is agreed to by the Administrative Agent in its reasonable discretion); (ii) the range of discounts to par (the “Discount Range”) expressed as a range of prices per $1,000 (in increments of $5), at which the applicable Borrower would be willing to purchase Term Loans of each applicable Class in such Auction; and (iii) the date on which such Auction will conclude, on which date Return Bids (as defined below) will be due by 1:00 p.m. (New York time) (as such date and time may be extended by the Auction Manager, such time the “Expiration Time”). Such Expiration Time may be extended for a period not exceeding three (3) Business Days upon notice by the applicable Borrower to the Auction Manager received not less than 24 hours before the original Expiration Time;provided that only two extensions per offer shall be permitted (unless otherwise approved by the Auction Manager prior to the date of the applicable Expiration Time). An Auction shall be regarded as a “failed auction” in the event that either (x) the applicable Borrower withdraws such Auction in accordance with the terms hereof or (y) the Expiration Time occurs with no Qualifying Bids (as defined below) having been received. In the event of a

B-1

failed auction, the applicable Borrower shall not be permitted to deliver a new Auction Notice prior to the date occurring three (3) Business Days after such withdrawal or Expiration Time, as the case may be. Notwithstanding anything to the contrary contained herein, the applicable Borrower shall not initiate any Auction by delivering an Auction Notice to the Auction Manager until after the conclusion (whether successful or failed) of the previous Auction (if any), whether such conclusion occurs by withdrawal of such previous Auction or the occurrence of the Expiration Time of such previous Auction.

2.Reply Procedures. In connection with any Auction, each Term Lender of each applicable Class wishing to participate in such Auction shall, prior to the Expiration Time, provide the Auction Manager with a notice of participation, in the form included in the respective offering document (each, a “Return Bid”) which shall specify (i) a discount to par that must be expressed as a price per $1,000 (in increments of $5) in principal amount of Term Loans of each applicable Class (the “Reply Price”) within the Discount Range and (ii) the principal amount of Term Loans of each applicable Class, in an amount not less than $1,000,000 or an integral multiple of $1,000 in excess thereof, that such Lender offers for sale at its Reply Price (the “Reply Amount”). A Term Lender may submit a Reply Amount that is less than the minimum amount and incremental amount requirements described above only if the Reply Amount comprises the entire amount of the Term Loans of each applicable Class held by such Term Lender. Term Lenders may only submit one Return Bid per Auction but each Return Bid may contain up to three (3) component bids, each of which may result in a separate Qualifying Bid and each of which will not be contingent on any other component bid submitted by such Term Lender resulting in a Qualifying Bid. In addition to the Return Bid, the participating Term Lender must execute and deliver, to be held by the Auction Manager, an assignment and acceptance in the form included in the offering document (each, an “Auction Assignment and Assumption”). The applicable Borrower will not purchase any Term Loans of any applicable Class at a price that is outside of the applicable Discount Range, nor will any Return Bids (including any component bids specified therein) submitted at a price that is outside such applicable Discount Range be considered in any calculation of the Applicable Threshold Price.

3.Acceptance Procedures. Based on the Reply Prices and Reply Amounts received by the Auction Manager, the Auction Manager, in consultation with the applicable Borrower, will calculate the lowest purchase price (the “Applicable Threshold Price”) for such Auction within the Discount Range for such Auction that will allow the applicable Borrower to complete the Auction by purchasing the full Auction Amount (or such lesser amount of Term Loans for which the applicable Borrower has received Qualifying Bids). The applicable Borrower shall purchase Term Loans of each applicable Class from each Term Lender whose Return Bid is within the Discount Range and contains a Reply Price that is equal to or less than the Applicable Threshold Price (each, a “Qualifying Bid”). All Term Loans included in Qualifying Bids (including multiple component Qualifying Bids contained in a single Return Bid) received at a Reply Price lower than the Applicable Threshold Price will be purchased at such applicable Reply Prices and shall not be subject to proration.

4.Proration Procedures. All Term Loans of each applicable Class offered in Return Bids (or, if applicable, any component thereof) constituting Qualifying Bids at the Applicable Threshold Price will be purchased at the Applicable Threshold Price;provided that if the aggregate principal amount (calculated on the face amount thereof) of all Term Loans of any

B-2

applicable Class for which Qualifying Bids have been submitted in any given Auction at the Applicable Threshold Price would exceed the remaining portion of the Auction Amount (after deducting all Term Loans of such Class to be purchased at prices below the Applicable Threshold Price), the applicable Borrower shall purchase the Term Loans of such Class for which the Qualifying Bids submitted were at the Applicable Threshold Price ratably based on the respective principal amounts offered and in an aggregate amount equal to the amount necessary to complete the purchase of the Auction Amount. No Return Bids or any component thereof will be accepted above the Applicable Threshold Price.

5.Notification Procedures. The Auction Manager will calculate the Applicable Threshold Price and post the Applicable Threshold Price and proration factor onto an internet or intranet site (including an IntraLinks, SyndTrak or other electronic workspace) in accordance with the Auction Manager’s standard dissemination practices by 4:00 p.m. New York time on the same Business Day as the date the Return Bids were due (as such due date may be extended in accordance with thisExhibit B). The Auction Manager will insert the principal amount of Term Loans of each applicable Class to be assigned and the applicable settlement date into each applicable Auction Assignment and Assumption received in connection with a Qualifying Bid. Upon the request of the submitting Lender, the Auction Manager will promptly return any Auction Assignment and Assumption received in connection with a Return Bid that is not a Qualifying Bid.

6.Auction Assignment and Assumption. Each Auction Notice and Auction Assignment and Assumption shall contain the following representations, warranties and covenants by the applicable Borrower:

The conditions set forth inSection 2.20(a) of the Credit Agreement have each been satisfied on and as of the date hereof, except to the extent that such conditions refer to conditions that must be satisfied as of a future date, in which case the applicable Borrower must terminate any Auction if it fails to satisfy one of more of the conditions which are required to be met at the time which otherwise would have been the time of purchase of Term Loans of any applicable Class pursuant to an Auction.

7.Additional Procedures. Once initiated by an Auction Notice, the applicable Borrower may withdraw an Auction only in the event that, (i) as of such time, no Qualifying Bid has been received by the Auction Manager or (ii) the applicable Borrower has failed to meet a condition set forth inSection 2.20 of the Credit Agreement. Furthermore, in connection with any Auction, upon submission by a Lender of a Return Bid, such Lender will not have any withdrawal rights. Any Return Bid (including any component bid thereof) delivered to the Auction Manager may not be modified, revoked, terminated or cancelled by a Lender. However, an Auction may become void if the conditions to the purchase of Term Loans of any applicable Class by the applicable Borrower required by the terms and conditions ofSection 2.20 of the Credit Agreement are not met. The purchase price in respect of each Qualifying Bid for which purchase by the applicable Borrower is required in accordance with the foregoing provisions shall be paid directly by the applicable Borrower to the respective assigning Lender on a settlement date as determined jointly by the applicable Borrower and the Auction Manager (which shall be not later than ten (10) Business Days after the date Return Bids are due). The applicable Borrower shall execute each applicable Auction Assignment and Assumption received

B-3

in connection with a Qualifying Bid. All questions as to the form of documents and validity and eligibility of Term Loans of each applicable Class that are the subject of an Auction will be determined by the Auction Manager, in consultation with the applicable Borrower, and their determination will be final and binding so long as such determination is not inconsistent with the terms ofSection 2.20 of the Credit Agreement or thisExhibit B. The Auction Manager’s interpretation of the terms and conditions of the offering document, in consultation with the applicable Borrower, will be final and binding so long as such interpretation is not inconsistent with the terms ofSection 2.20 of the Credit Agreement or thisExhibit B. None of the Administrative Agent, the Auction Manager, any other Agent-Related Person or any of their respective affiliates assumes any responsibility for the accuracy or completeness of the information concerning the applicable Borrower, the Loan Parties, or any of their affiliates (whether contained in an offering document or otherwise) or for any failure to disclose events that may have occurred and may affect the significance or accuracy of such information. ThisExhibit B shall not require the applicable Borrower to initiate any Auction.

Each reference to a Loan Party, Guarantor and Borrower (as applicable) in the Credit Agreement shall be deemed to include the applicable Closing Date Loan Party.

SUBSIDIARY GUARANTY

Reference is hereby made to the Credit Agreement dated as of June 17, 2014 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), by and among HORIZON PHARMA, INC., a Delaware corporation (“Horizon”), the LENDERS from time to time party thereto and CITIBANK, N.A., as Administrative Agent and Collateral Agent, and from and after the time they become parties to the Credit Agreement, VIDARA THERAPEUTICS INTERNATIONAL LTD. (“Irish Holdco”), LUTEUS CAPITAL LIMITED (“Irish Intermediate Holdco”), HORIZON PHARMA FINANCE S.À R.L. (“Luxco”) and HAMILTON HOLDINGS (USA), INC. (the “U.S. Borrower”) (the “Credit Agreement”). Unless otherwise defined herein, terms defined in the Credit Agreement and used herein shall have the meanings given to them in the Credit Agreement.

Section 1.Subsidiary Guaranty. (a) Each of the undersigned (the “Subsidiary Guarantors”) hereby jointly and severally guarantees to each Secured Party as hereinafter provided, as primary obligor and not as surety, the payment of the Secured Obligations in full in cash when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) strictly in accordance with the terms thereof. The Subsidiary Guarantors hereby further jointly and severally agree that if any of the Secured Obligations are not paid in full in cash when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise), each Subsidiary Guarantor will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Secured Obligations, the same will be promptly paid in full in cash when due (whether at extended maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) in accordance with the terms of such extension or renewal.

(b) Each Subsidiary Guarantor, and by its acceptance of this Subsidiary Guaranty, the Administrative Agent and each other Secured Party, hereby confirms that it is the intention of all such Persons that this Subsidiary Guaranty and the Obligations of each Subsidiary Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of any Debtor Relief Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Subsidiary Guaranty and the Obligations of each Subsidiary Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the other Secured Parties and the Subsidiary Guarantors hereby irrevocably agree that the Obligations of each Subsidiary Guarantor under this Subsidiary Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Subsidiary Guarantor under this Subsidiary Guaranty not constituting a fraudulent transfer or conveyance under applicable law after giving full effect to such Subsidiary Guarantor’s contribution rights but before taking into account any liabilities of such Subsidiary Guarantor under any other guarantee of such Subsidiary Guarantor other than any other guarantee of any obligations that are secured on a pari passu basis with the Obligations.

Section 2.Representations and Warranties.

E-1

(a)Organization; Powers. The undersigned Subsidiary Guarantor is duly organized or incorporated, as the case may be, and validly existing and (to the extent the concept is applicable in such jurisdiction) in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in and (to the extent the concept is applicable in such jurisdiction) is in good standing in, every jurisdiction where such qualification is required.

(b)Authorization; Enforceability. The execution and delivery of this Subsidiary Guaranty are within each undersigned Subsidiary Guarantor’s corporate or other organizational powers and have been duly authorized by all necessary corporate or other organizational actions and, if required, actions by all necessary corporate or other organizational actions and, if required, actions by shareholders, members or equity holders. This Subsidiary Guaranty constitutes a legal, valid and binding obligation of each undersigned Subsidiary Guarantor, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganizational, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

(c)Conflicting Laws and Contracts. From and after the Closing Date, neither the execution and delivery by each Subsidiary Guarantor of this Subsidiary Guaranty, nor compliance with the terms and provisions hereof will (i) violate any applicable law or regulation (except such non-compliance that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect) or the charter, by-laws or other organizational documents of such Subsidiary Guarantor or any order of any Governmental Authority, (ii) violate in any material respect or result in a default under any indenture, material agreement or other material instrument binding upon such Grantor or its assets, or give rise to a right thereunder to require any payment to be made by such Grantor, or (iii) result in the creation or imposition of any Lien on any asset of such Grantor, other than Liens created under this Subsidiary Guaranty or the other Loan Documents.

Section 3.Covenants. From and after the Closing Date, each Subsidiary Guarantor covenants and agrees that, until the Maturity Date has occurred, such Guarantor will perform and observe all of the terms, covenants and agreements set forth in the Loan Documents on its part to be performed or observed or that Irish Holdco or the Borrowers have agreed to cause such Guarantor to perform or observe and will cause each of its Subsidiaries to perform and observe all of the terms, covenants and agreements set forth in the Loan Documents that Irish Holdco or the Borrowers have agreed to cause such Subsidiaries to perform or observe.

Section 4.Obligations Unconditional. (a) The obligations of the Subsidiary Guarantors under this Subsidiary Guaranty are absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of any of the Loan Documents or other documents relating to the Secured Obligations, or any substitution, release, impairment or exchange of any other guarantee of or security for any of the Secured Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or

E-2

guarantor (other than payment in full in cash of the Secured Obligations, other than Unliquidated Obligations for which no claim has been made), it being the intent of this Section 4 that the obligations of each Subsidiary Guarantor hereunder shall be absolute and unconditional under any and all circumstances. Each of the Subsidiary Guarantors agrees that they shall have no right of subrogation, indemnity, reimbursement or contribution against a Borrower or any other Subsidiary Guarantor for amounts paid under this Subsidiary Guaranty until such time as the Secured Obligations (other than Unliquidated Obligations for which no claim has been made) have been paid in full in cash and the Commitments have expired or terminated.

(b) Without limiting the generality of the foregoing, it is agreed that, to the fullest extent permitted by law, the occurrence of any one or more of the following shall not alter or impair the liability of the Subsidiary Guarantors hereunder, which shall remain absolute and unconditional as described above:

(i) at any time or from time to time, without notice to the Subsidiary Guarantors, the time for any performance of or compliance with any of the Secured Obligations shall be extended, or such performance or compliance shall be waived;

(ii) any of the acts mentioned in any of the provisions of any of the Loan Documents or other documents relating to the Secured Obligations shall be done or omitted;

(c) With respect to its obligations hereunder, each of the Subsidiary Guarantors hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Administrative Agent, the Collateral Agent or any other holder of the Secured Obligations exhaust any right, power or remedy or proceed against any Person under any of the Loan Documents or other documents relating to the Secured Obligations, or against any other Person under any other guarantee of, or security for, any of the Secured Obligations.

E-3

Section 5.Reinstatement. The obligations of the Subsidiary Guarantors under this Subsidiary Guaranty shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Person in respect of the Secured Obligations is rescinded or must be otherwise restored by any holder of any of the Secured Obligations, whether as a result of any proceedings under any Debtor Relief Law, and each of the Subsidiary Guarantors agrees that they will jointly and severally indemnify the Administrative Agent and each holder of the Secured Obligations on demand for all reasonable costs and expenses (including, without limitation, the fees, charges and disbursements of counsel) incurred by the Administrative Agent or such holder of the Secured Obligations in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any proceedings under any debtor relief law.

Section 6.Certain Additional Waivers. Each of the Subsidiary Guarantors further agrees that they shall have no right of recourse to security for the Secured Obligations, except through the exercise of rights of subrogation pursuant to Section 4 of this Subsidiary Guaranty and through the exercise of rights of contribution pursuant to Section 8 hereof.

Section 7.Remedies. Each of the Subsidiary Guarantors agrees that, to the fullest extent permitted by law, as between the Subsidiary Guarantors, on the one hand, and the Administrative Agent, the Collateral Agent and the other holders of the Secured Obligations, on the other hand, the Secured Obligations may be declared to be forthwith due and payable as provided in Article VII of the Credit Agreement (and shall be deemed to have become automatically due and payable in the circumstances provided in said Article VII thereof) for purposes of Section 1 notwithstanding any stay, injunction or other prohibition preventing such declaration (or preventing the Secured Obligations from becoming automatically due and payable) as against any other Person and that, in the event of such declaration (or the Secured Obligations being deemed to have become automatically due and payable), the Secured Obligations (whether or not due and payable by any other Person) shall forthwith become due and payable by the Subsidiary Guarantors for purposes of Section 1. Each of the Subsidiary Guarantors acknowledges and agrees that their respective obligations hereunder are secured in accordance with the terms of the Collateral Documents and that the holders of the Secured Obligations may exercise their remedies thereunder in accordance with the terms thereof.

Section 8.Rights of Contribution. Each of the Subsidiary Guarantors agrees that, in connection with payments made hereunder, each Subsidiary Guarantor shall have contribution rights against the other Subsidiary Guarantors as permitted under applicable law. Such contribution rights shall be subordinate and subject in right of payment to the obligations of such Subsidiary Guarantors under the Loan Documents and no Subsidiary Guarantor shall exercise such rights of contribution until all Secured Obligations (other than Unliquidated Obligations for which no claim has been made) have been paid in full in cash and the Commitments have terminated.

Section 9.Guarantee of Payment; Continuing Guarantee. The guarantee given by the Subsidiary Guarantors in this Subsidiary Guaranty is a guaranty of payment and not of collection, is a continuing guarantee, and shall apply to all Secured Obligations whenever arising.

E-4

Section 10.Guarantee Limitations. Notwithstanding anything to the contrary contained in the Credit Agreement or in any other Loan Documents, the guarantee obligations of any Subsidiary Guarantor established in Luxembourg (a “Luxembourg Guarantor”) in respect of the obligations of Irish Holdco or any of its Subsidiaries which is not a direct or indirect subsidiary of such relevant Luxembourg Guarantor shall be limited at any time to an aggregate amount not exceeding 95% of the greater of:

(a) the Luxembourg Guarantor’s own funds (capitaux propres), as referred to in article 34 of the Luxembourg Law dated 19 December 2002 concerning the trade and companies register and the accounting and annual accounts of undertakings, as amended (the “2002 Law”), increased by the amount of any debts owed to a company of the same group of the Luxembourg Guarantor, as shown in (x) the latest interim financial statements available (if any), at the date of demand of payment under the Credit Agreement or, if not available, (y) the latest annual financial statements (comptes annuels) available at the date of demand of payment under this Agreement; and

(b) the Luxembourg Guarantor’s own funds (capitaux propres), as referred to in article 34 of the 2002 Law, increased by the amount of any debts owed to a company of the same group of the Subsidiary Guarantor, at the date of entry into this Subsidiary Guaranty.

The limitation set forth under items (i) and (ii) above shall not apply to any amounts borrowed under the Credit Agreement and made available, in any form whatsoever, to the Luxembourg Guarantor or any of its direct or indirect subsidiaries.

Section 11.Additional Subsidiaries. Pursuant to Section 5.09 of the Credit Agreement, a Subsidiary of Irish Holdco that was not a Subsidiary Guarantor on the Closing Date may be required to enter into this Subsidiary Guaranty as a Subsidiary Guarantor thereafter. A Subsidiary of Irish Holdco that is not so required to enter into this Subsidiary Guaranty as a Subsidiary Guarantor may elect to enter into this Subsidiary Guaranty as a Subsidiary Guarantor. Upon execution and delivery by the Collateral Agent and the applicable Subsidiary of an instrument in the form of Annex I hereto (which may be modified as required to comply with local laws in accordance with the Agreed Security Principles, if applicable), such Subsidiary shall become a Subsidiary Guarantor hereunder with the same force and effect as if originally named as a Subsidiary Guarantor herein (subject to any such modifications in accordance with the Agreed Security Principles). The execution and delivery of any such instrument shall not require the consent of any other Loan Party hereunder. The rights and obligations of each Loan Party hereunder shall remain in full force and effect notwithstanding the addition of any new Subsidiary Guarantor as a party to this Subsidiary Guaranty.

Section 12.Effectiveness. This Subsidiary Guaranty becomes effective upon its execution and delivery provided that any guarantee provided for herein shall not apply to the Secured Obligations until such time as the first Secured Obligations come into existence and once the Closing Date has occurred. If the Closing Date does not occur by the 2014 Term Loan Commitment Expiration Date, the obligations of the Subsidiary Guarantors hereunder shall cease to have effect.

E-5

Section 13.Severability. Any provision of this Subsidiary Guaranty which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 14.Counterparts. This Subsidiary Guaranty may be executed in counterparts, each of which shall constitute an original. Delivery of an executed signature page to this Subsidiary Guaranty by facsimile or by email as a “.pdf” or “.tif” attachment shall be as effective as delivery of a manually executed counterpart of this Subsidiary Guaranty.

Section 16.Governing Law; Jurisdiction; Consent to Service of Process; Foreign Process Agent. (a) This Subsidiary Guaranty and each other Loan Document (except, as to any other Loan Document, as expressly set forth therein) shall be construed in accordance with and governed by the law of the State of New York.

(b) Each of the Subsidiary Guarantors hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Subsidiary Guaranty or any other Loan Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Subsidiary Guaranty or any other Loan Document against any Loan Party or its properties in the courts of any jurisdiction.

(c) Each of the Subsidiary Guarantors hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which they may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Subsidiary Guaranty or any other Loan Document in any court referred to in paragraph (b) of this Section 16. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Subsidiary Guaranty irrevocably consents to service of process in the manner provided for notices in Section 9.01 of the Credit Agreement. Nothing in this Subsidiary Guaranty or any other Loan Document will affect the right of any party to this Subsidiary Guaranty to serve process in any other manner permitted by law.

E-6

(e) Each of the Subsidiary Guarantors hereby irrevocably and unconditionally appoints the U.S. Borrower and its successors hereunder (the “Process Agent”), as its agent to receive on behalf of the Subsidiary Guarantors and their respective property all writs, claims, process and summonses in any action or proceeding brought against it in the State of New York.

Failure by the Process Agent to give notice to a Subsidiary Guarantor or failure of a Subsidiary Guarantor to receive notice of such service of process shall not impair or affect the validity of such service on the Process Agent or the Subsidiary Guarantor, or of any judgment based thereon. Each of the Subsidiary Guarantors covenants and agrees that it shall take any and all reasonable action, including the execution and filing of any and all documents, that may be necessary to continue the delegation of the Process Agent above in full force and effect, and to cause the Process Agent to act as such. Each Subsidiary Guarantor hereto further covenants and agrees to maintain at all times an agent with offices in New York City to act as its Process Agent. Nothing herein shall in any way be deemed to limit the ability to serve any such writs, process or summonses in any other manner permitted by applicable law.
