LOAN AGREEMENT

THIS LOAN AGREEMENT (this “Agreement”), dated as of April 6, 2023 (the “Effective Date”) by and among IMMUNOGEN, INC., a Massachusetts corporation (as “Borrower” and a Credit Party), the Guarantors signatory hereto or otherwise party hereto from time to time, as additional Credit Parties, BIOPHARMA CREDIT PLC, a public limited company incorporated under the laws of England and Wales with company number 10443190 (as the “Collateral Agent”), BPCR LIMITED PARTNERSHIP, a limited partnership established under the laws of England and Wales with registration number LP020944 (as a “Lender”), and BIOPHARMA CREDIT INVESTMENTS V (MASTER) LP, a Cayman Islands exempted limited partnership acting by its general partner, BioPharma Credit Investments V GP LLC (as a “Lender”), provides the terms on which each Lender shall make, and Borrower shall repay, the Credit Extensions (as hereinafter defined). The parties hereto agree as follows:

ACCOUNTING AND OTHER TERMS

Except as otherwise expressly provided herein, all accounting terms not otherwise defined in this Agreement shall have the meanings assigned to them in conformity with GAAP. Calculations and determinations must be made following GAAP. If at any time any change in GAAP would affect the computation of any financial requirement set forth in any Loan Document (including for purposes of measuring compliance with any provision of Section 6), and either Borrower or the Collateral Agent shall so request, the Collateral Agent and Borrower shall negotiate in good faith to amend such requirement to preserve the original intent thereof in light of such change in GAAP; provided, that, until so amended, (x) such requirement shall continue to be computed in accordance with GAAP prior to such change therein and (y) all financial statements, Compliance Certificates and similar documents provided, delivered or submitted hereunder shall be provided, delivered or submitted together with a reconciliation between the calculations and amounts set forth therein before and after giving effect to such change in GAAP. Notwithstanding any other provision contained herein, all terms of an accounting or financial nature used herein shall be construed, and all computations of amounts referred to herein, including in Section 5 and Section 6 shall be made, without giving effect to any (a) election under ASC 825-10 (or any other Financial Accounting Standards Board Accounting Standards Codification (“ASC”) or Financial Accounting Standard or Applicable Accounting Standard (including IFRS 9) having a similar result or effect) to value any Indebtedness or other liabilities of any Credit Party or any Subsidiary of any Credit Party at “fair value” and (b) any treatment of Indebtedness in respect of convertible debt instruments under ASC 470-20 (or any other ASC or Financial Accounting Standard or Applicable Accounting Standard having a similar result or effect) to value any such Indebtedness in a reduced or bifurcated manner as described therein, and such Indebtedness shall at all times be valued at the full stated principal amount thereof. Notwithstanding anything to the contrary above or in the definition of “Capital Lease Obligations”, all obligations of any Person that are or would have been treated as operating leases for purposes of GAAP prior to the effectiveness of ASC 842 shall continue to be accounted for as operating leases for all purposes hereunder or under any other Loan Documents (whether or not such operating lease obligations were in effect on such date) notwithstanding the fact that such obligations are required in accordance with ASC 842 (on a prospective or retroactive basis or otherwise) to be treated as Capital Leases. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein. All references to “Dollars” or “$” are United States Dollars, unless otherwise noted.

It being understood and agreed that Borrower or such other Credit Party may from time to time update certain information in the Perfection Certificate, the Disclosure Letter or such other disclosure schedules attached to Loan Documents after the Effective Date to the extent expressly permitted by one or more provisions in this Agreement and the other Loan Documents to reflect changes since the Effective Date, provided that in no event may the Perfection Certificate, the Disclosure Letter or such other disclosure schedules be updated in a manner that would reflect or evidence a Default or Event of Default (with or without such update).

For purposes of Sections 5 and 6 and solely with respect to the amount of any Indebtedness, Investment or other transaction made or consummated in a currency other than Dollars, no Default or Event of Default shall be deemed to have occurred after the time such Indebtedness, Investment or other transaction is incurred, made or consummated (so long as such Indebtedness, Investment or other transaction, at the time incurred, made or consummated, was permitted hereunder) solely as a result of changes in rates of currency exchange occurring over time.

The Collateral Agent does not warrant or accept responsibility for, and shall not have any liability with respect to (a) the continuation of, administration of, submission of, calculation of or any other matter related to the Term SOFR Reference Rate or Term SOFR, or any component definition thereof or rates referred to in the definition thereof, or any alternative, successor or replacement rate thereto (including any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement) will be similar to, or produce the same value or economic equivalence of, or have the same volume or liquidity as, the Term SOFR Reference Rate, Term SOFR or any other Benchmark prior to its discontinuance or unavailability, or (b) the effect, implementation or composition of any Conforming Changes. The Collateral Agent and its affiliates or other related entities may engage in transactions that affect the calculation of the Term SOFR Reference Rate, Term SOFR, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower. The Collateral Agent may select information sources or services in its reasonable discretion to ascertain the Term SOFR Reference Rate, Term SOFR or any other Benchmark, in each case pursuant to the terms of this Agreement, and shall have no liability to Borrower, any Lender or any other Person for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service.

2LOANS AND TERMS OF PAYMENT

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

2.2Term Loans.

(a)Availability. Subject to the terms and conditions of this Agreement (including Sections 3.1, 3.2 and 3.5):

(i)Borrower agrees to request in accordance with Section 3.5, and each Lender severally agrees to make, a term loan to Borrower on the Tranche A Closing Date in an original principal amount equal to such Lender’s Tranche A Loan Commitment (collectively, the “Tranche A Loans”); and

(ii)At Borrower’s election pursuant to Section 3.5, and subject to the prior satisfaction of the conditions precedent set forth in Section 3.2, each Lender severally agrees to make a term loan to Borrower on the Tranche B Closing Date in an original principal amount not greater than such Lender’s Tranche B Commitment (collectively, the “Tranche B Loans”).

After repayment or prepayment (in whole or in part), no Term Loan (or any portion thereof) may be re-borrowed.

(b)Repayment.

(i)With respect to any and all Term Loans, Borrower shall make eight (8) equal quarterly principal payments of the Term Loans, each in an amount equal to one-eighth of the cumulative principal balance of all Term Loans commencing on the first Payment Date that occurs during the 13^th calendar quarter following the Tranche A Closing Date (the “Initial Principal Payment Date”) and continuing through the Term Loan Maturity Date; provided, however, that, so long as (x) as of the Initial Principal Payment Date (A) no Default or Event of Default has occurred and is continuing, and (B) no Material Adverse Change or Withdrawal Event has occurred, and (y) the trailing twelve-month Net Sales with respect to Initial Product exceeds $[***] as of the end of the last month of the 12^th calendar quarter following the Tranche A Closing Date, Borrower may elect by irrevocable written notice to the Collateral Agent (the “Delayed Amortization Notice”) to postpone making the quarterly payments of principal

-2-

otherwise due during the 13^th through 16^th calendar quarters following the Tranche A Closing Date and to make four quarterly payments of principal of the Term Loans, each in an amount equal to one-fourth of the cumulative principal balance of the Term Loans, commencing on the first Payment Date that occurs during the 17^th calendar quarter following the Tranche A Closing Date and continuing through the Term Loan Maturity Date; provided, further, that, in such case Borrower shall deliver to the Collateral Agent the Delayed Amortization Notice no later than ten (10) Business Days prior to the first Payment Date that occurs during the 13^th calendar quarter following the Tranche A Closing Date.

(ii)The Term Loans, including all unpaid principal thereunder (and, for the avoidance of doubt, all accrued and unpaid interest, all due and unpaid Lender Expenses and any and all other outstanding amounts payable under the Loan Documents), shall be due and payable in full on the Term Loan Maturity Date.

The Collateral Agent will promptly notify each Lender of its receipt of such notice, and the amount of such Lender’s Applicable Percentage of such prepayment. Notwithstanding anything in this Section 2.2(c)(i) to the contrary, Borrower may rescind any notice of prepayment under this Section 2.2(c)(i) if such prepayment would have resulted from a refinancing of the Term Loans or other contingent transaction, which refinancing or transaction shall not be consummated or shall otherwise be delayed (in which case, a new notice shall be required to be sent in connection with any subsequent prepayment).

(ii)Upon a Change in Control, Borrower shall promptly, and in any event no later than ten (10) days after the consummation of such Change in Control, notify the Collateral Agent in writing of the occurrence of a Change in Control, which notice shall include reasonable detail as to the nature, timing and other circumstances of such Change in Control (such notice, a “Change in Control Notice”). Borrower shall prepay in full all of the Term Loans advanced by Lenders under this Agreement, no later than [***] days after the consummation of such Change in Control, in an amount equal to the sum of (A) all unpaid principal and any and all accrued and unpaid interest thereon through the date of prepayment (such interest to be calculated based on Term SOFR for the Interest Period during which such Change of Control is consummated), and (B) any and all amounts payable with respect to the prepayment under this Section 2.2(c)(ii) pursuant to Section 2.2(e) and Section 2.2(f) (as applicable), together with any and all other amounts payable or accrued and not yet paid under this Agreement and the other Loan Documents (including pursuant to Section 2.4). The Collateral Agent will promptly notify each Lender of its receipt of the Change in Control Notice, and the amount of such Lender’s Applicable Percentage of such prepayment.

(d)Prepayment Application. Any prepayment of the Term Loans pursuant to Section 2.2(c) or as a result of the acceleration of the maturity of the Term Loans pursuant to Section 8.1(a) (together with the accompanying Makewhole Amount and Prepayment Premium that is payable pursuant to Section 2.2(e) and Section 2.2(f) as applicable) shall be paid to Lenders in accordance with their respective Applicable Percentages for application to the Obligations in the following order: (i) first, to due and unpaid Lender Expenses; (ii) second, to due and unpaid Additional Consideration; (iii) third, to accrued and unpaid interest at the Default Rate incurred pursuant to Section 2.3(b), with respect to past due amounts, if any; (iv) fourth, without duplication of amounts paid pursuant to clause

-3-

(iii) above, to accrued and unpaid interest at the Term Loan Rate; (v) fifth, to the Prepayment Premium; (vi) sixth, to the Makewhole Amount, if applicable; (vii) seventh, to the outstanding principal amount of the Term Loans being prepaid; and (viii) eighth, to any remaining amounts then due and payable under this Agreement and the other Loan Documents.

(e)Makewhole Amount.

(i)Any prepayment of the Tranche A Loan by Borrower (A) pursuant to Section 2.2(c), or (B) as a result of the acceleration of the maturity of the Term Loans pursuant to Section 8.1(a), in each case occurring prior to the 3^rd-year anniversary of the Tranche A Closing Date shall, in any such case, be accompanied by payment of an amount equal to the Tranche A Makewhole Amount.

(ii)Any prepayment of the Tranche B Loan by Borrower (A) pursuant to Section 2.2(c), or (B) as a result of the acceleration of the maturity of the Term Loans pursuant to Section 8.1(a), in each case occurring prior to the 3^rd-year anniversary of the Tranche B Closing Date shall, in any such case, be accompanied by payment of an amount equal to the Tranche B Makewhole Amount.

(f)Prepayment Premium.

(i)Any prepayment of the Tranche A Loan by Borrower (A) pursuant to Section 2.2(c), or (B) as a result of the acceleration of the maturity of the Term Loans pursuant to Section 8.1(a), shall, in any such case, be accompanied by payment of an amount equal to the Tranche A Prepayment Premium.

(ii)Any prepayment of the Tranche B Loan by Borrower (A) pursuant to Section 2.2(c), or (B) as a result of the acceleration of the maturity of the Term Loans pursuant to Section 8.1(a), shall, in any such case, be accompanied by payment of an amount equal to the Tranche B Prepayment Premium.

(g)Any Makewhole Amount or Prepayment Premium payable as a result of any prepayment of the Term Loans pursuant to Section 2.2(c) or as a result of the acceleration of the maturity of the Term Loans pursuant to Section 8.1(a), shall be presumed to be the liquidated damages sustained by each applicable Lender as the result of the early redemption and repayment of such Term Loan Notes and Borrower agrees that it is reasonable under the circumstances currently existing. BORROWER EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE REQUIREMENTS OF LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF ANY MAKEWHOLE AMOUNT OR PREPAYMENT PREMIUM IN CONNECTION WITH ANY SUCH PREPAYMENT OR ACCELERATION OR OTHERWISE. Borrower expressly agrees that (to the fullest extent it may lawfully do so) that: (i) each Makewhole Amount and Prepayment Premium is reasonable and is the product of an arm’s-length transaction among sophisticated business people, ably represented by counsel; (ii) each Makewhole Amount and Prepayment Premium shall be payable notwithstanding the then-prevailing market rates at the time payment thereof is made; (iii) there has been a course of conduct among Lenders and Borrower giving specific consideration in this transaction for such agreement to pay each Makewhole Amount and Prepayment Premium; and (iv) Borrower shall be estopped hereafter from claiming differently than as agreed to in this Section 2.2(g) and Section 8.6. Borrower expressly acknowledges that its agreement to pay the Makewhole Amount and Prepayment Premium, as the case may be, to applicable Lenders as herein described is a material inducement to such Lenders to make any Credit Extension. Without affecting any of any Lender’s rights or remedies hereunder or in respect hereof, if Borrower fails to pay the applicable Makewhole Amount or Prepayment Premium when due, then the amount thereof shall thereafter bear interest until paid in full at the Default Rate.

2.3Payment of Interest on the Term Loans.

(a)Interest Rate.

-4-

(i)Subject to Section 2.3(b) below, the principal amount outstanding under each Term Loan shall accrue interest at a per annum rate equal to Term SOFR for the Interest Period therefor plus the Applicable Margin (the “Term Loan Rate”), which interest shall be payable quarterly in arrears in accordance with this Section 2.3.

(ii)Interest shall accrue on each Term Loan commencing on, and including, the day on which such Term Loan is made, and shall accrue on such Term Loan, or any portion thereof, through and including the day on which such Term Loan or such portion is paid.

(iii)Interest is due and payable quarterly on each Interest Date, as calculated by the Collateral Agent (which calculations shall be deemed correct absent manifest error, provided that the Collateral Agent shall provide evidence of such calculation upon Borrower’s written request), commencing on the Interest Date occurring in the calendar quarter immediately following the Closing Date; provided, however, that if any such date is not a Business Day, the applicable interest shall be due and payable on the immediately preceding Business Day.

(b)Default Rate. In the event Borrower fails to pay any of the Obligations when due, or upon the commencement and during the continuance of an Insolvency Proceeding of Borrower, or upon the occurrence and during the continuance of any other Event of Default, immediately (and without notice or demand by any Lender or the Collateral Agent for payment thereof), such past due Obligations shall accrue interest at a rate per annum which is [***] percentage points [***] above the rate that is otherwise applicable thereto (the “Default Rate”), and, notwithstanding anything to the contrary in Section 2.3(a) above, such interest shall be payable entirely in cash on demand of any Lender or the Collateral Agent. Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment of any Obligations and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of the Collateral Agent or any Lender.

(c)360-Day Year. Interest payable under each Term Loan shall be computed on the basis of a year of 360 days, and in each case shall be payable for the actual number of days elapsed.

(d)Minimum interest payments – Swiss Withholding Tax. The rates of interest provided for in this Agreement are minimum interest rates. When entering into this Agreement, the parties hereto have assumed that the interest payable at the rates set out in this Section 2.3 or in other Sections of this Agreement, if any, is not and will not become subject to Swiss Withholding Tax. This notwithstanding, if a Tax deduction is required by Swiss domestic tax law in respect of any interest payable by any Credit Party under a Loan Document and should it be unlawful for any Swiss Guarantor to comply with Section 2.6 for any reason, where this would otherwise be required by the terms of Section 2.6, then (i) the applicable interest rate in relation to that interest payment shall be the interest rate which would have applied to that interest payment as provided for by this Section 2.3 divided by one minus the rate at which the relevant Tax deduction is required to be made under Swiss domestic tax law and/or applicable double taxation treaties (where the rate at which the relevant Tax deduction is required to be made is for this purpose expressed as a fraction of one) and (ii) such Guarantor shall (x) pay the relevant interest at the adjusted rate in accordance with paragraph (i) above and (y) make the Tax deduction on the interest so recalculated, and all references to a rate of interest under the Loan Documents shall be construed accordingly.

(e)Payments. Except as otherwise expressly provided herein, all Term Loan payments and any other payments hereunder by (or on behalf of) Borrower shall be made on the date specified herein to such bank account of each applicable Lender as such Lender (or the Collateral Agent) shall have designated in a written notice to Borrower delivered on or before the Tranche A Closing Date (which such notice may be updated by such Lender (or the Collateral Agent) by written notice to Borrower from time to time after the Tranche A Closing Date). Except as otherwise expressly provided herein, interest is payable quarterly on each Interest Date. Payments of principal or interest received after 11:00 a.m. on such date are considered received at the opening of business on the next Business Day. When any payment is due on a day that is not a Business Day, such payment is due on the immediately preceding Business Day. All payments to be made by Borrower hereunder or under any other Loan Document, including payments of principal and interest made hereunder and pursuant to any other Loan Document, and all fees, expenses, indemnities and reimbursements, shall be made without set-off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds.

-5-

(f)Conforming Changes. In connection with the use or administration of Term SOFR, the Collateral Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. The Collateral Agent will promptly notify the Borrower and the Lenders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR.

(g)Benchmark Replacement Setting. Notwithstanding anything to the contrary herein or in any other Loan Document:

(i)Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (a) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (b) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5^th) Business Day after the date notice of such Benchmark Replacement is provided to Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Collateral Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required Lenders. If the Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a quarterly basis.

(ii)Conforming Changes. In connection with the implementation and administration of a Benchmark Replacement, the Collateral Agent, in consultation with the Borrower, will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document.

(iii)Notices; Standards for Decisions and Determinations. The Collateral Agent will promptly notify Borrower and the Lenders of (A) the implementation of any Benchmark Replacement and (B) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Collateral Agent will notify Borrower of (x) the removal or reinstatement of any tenor of a Benchmark pursuant to sub-clause (iv) below and (y) the commencement of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Collateral Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 2.3(f), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this Section 2.3(f).

(iv)Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (A) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate) and either (1) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Collateral Agent in its reasonable discretion or (2) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative, then the Collateral Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (B) if a tenor that was removed pursuant to sub-clause (A) above either (1) is

subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (2) is not, or is no longer, subject to an announcement that it is not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Collateral Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor.

2.4Expenses. Borrower shall pay to or reimburse (or pay directly on behalf of) the Collateral Agent and, as applicable, each Lender, [***] such Person’s reasonable and documented Lender Expenses incurred through and after the Effective Date, promptly after receipt of a written demand therefor by such Lender or the Collateral Agent (with, in the case of any Lender, a copy of such demand to the Collateral Agent), setting forth in reasonable detail such Person’s Lender Expenses.

2.5Requirements of Law; Increased Costs. In the event that any applicable Change in Law:

(a)Does or shall subject any Lender to any Tax of any kind whatsoever with respect to this Agreement, the Term Loans or any other Loan Documents (except, in each case, Indemnified Taxes, Taxes described in clause (b) through (h) of the definition of Excluded Taxes, and Connection Income Taxes);

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

(c)Does or shall impose on any Lender any other condition (other than Taxes, which are addressed in clause (a) above); and the result of any of the foregoing is to increase the cost to such Lender (as determined by such Lender in good faith using calculation methods customary in the industry) of making, renewing or maintaining the Term Loans or to reduce any amount receivable in respect thereof or to reduce the rate of return on the capital of such Lender or any Person controlling such Lender,

then, in any such case, such Lender shall notify Borrower in writing of the event by reason of which it has incurred additional costs or has reduced amounts receivable or rate of return, and submit to Borrower a certificate as to such additional costs or has reduced amounts receivable or rate of return containing the calculation thereof in reasonable detail, which shall be conclusive in the absence of manifest error. Borrower shall promptly, and no later than thirty (30) days of its receipt of the certificate described above, pay to such Lender, subject to the terms of this Section 2.5, any additional amounts necessary to compensate such Lender for such additional cost or reduced amounts receivable or rate of return as reasonably determined by such Lender with respect to this Agreement or the Term Loans made hereunder. The provisions of this Section 2.5 shall survive the termination of this Agreement and the payment of the outstanding Term Loans and all other Obligations. Failure or delay on the part of any such Lender to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital under this Section 2.5 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that Borrower shall not be under any obligation to compensate such Lender under this Section 2.5 with respect to increased costs or reductions with respect to any period prior to the date that is 180 days prior to the date of the delivery of the notice required pursuant to the foregoing provisions of this paragraph; provided, further, 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.

2.6Taxes; Withholding, Etc.

(a)All sums payable by any Credit Party hereunder and under the other Loan Documents shall (except to the extent required by Requirements of Law) be paid free and clear of, and without any deduction or withholding on account of, any Tax imposed, levied, collected, withheld or assessed by any Governmental Authority. In addition, Borrower agrees to pay, and shall indemnify and hold each Lender harmless from, Other Taxes, and as soon as practicable after the date of paying Other Taxes to a Governmental Authority, Borrower shall furnish to each Lender (as applicable, with a copy to the Collateral Agent) the original or a certified copy of a receipt evidencing payment thereof or other evidence reasonably satisfactory to such Lender.

-7-

(b)If any Credit Party or any other Person (“Withholding Agent”) is required by Requirements of Law to make any deduction or withholding on account of any Tax (as determined in the good faith discretion of such Withholding Agent) from any sum paid or payable by any Credit Party to any Lender under any of the Loan Documents: (i) such Withholding Agent shall notify such Lender in writing (with a copy to the Collateral Agent) of any such requirement or any change in any such requirement promptly after such Withholding Agent becomes aware of it; (ii) such Withholding Agent shall make any such withholding or deduction; (iii) such Withholding Agent shall pay any such Tax before the date on which penalties attach thereto, such payment to be made (if the liability to pay is imposed on any Credit Party) for its own account or (if that liability is imposed on such Lender, as the case may be) on behalf of and in the name of such Lender in accordance with Requirements of Law; (iv) if the Tax is an Indemnified Tax, the sum payable by such Credit Party in respect of which the relevant deduction, withholding or payment of Indemnified Tax is required shall be increased to the extent necessary to ensure that, after the making of that deduction, withholding or payment (including any deductions for Indemnified Taxes applicable to additional sums payable under this Section 2.6(b)), such Lender receives on the due date a net sum equal to what it would have received had no such deduction, withholding or payment of Indemnified Tax been required or made; and (v) as soon as practicable after paying any sum from which it is required by Requirements of Law to make any deduction or withholding, Borrower shall (or shall cause such Withholding Agent, if not Borrower, to) deliver to such Lender (with a copy to the Collateral Agent) evidence reasonably satisfactory to such Lender of such deduction, withholding or payment and of the remittance thereof to the relevant taxing or other Governmental Authority.

(c)The Borrower shall indemnify each Lender for [***] of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 2.6(c)) paid by such Lender and any liability (including any reasonable expenses) arising therefrom or with respect thereto whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Any indemnification payment pursuant to this Section 2.6(c) shall be made to the applicable Lender within ten (10) days from written demand therefor.

(d)Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to Borrower, at the time or times reasonably requested by Borrower, such properly completed and executed documentation reasonably requested by Borrower as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, such Lender, if reasonably requested by Borrower, shall deliver such other documentation prescribed by applicable law or reasonably requested by Borrower as will enable Borrower to determine whether or not such Lender is subject to backup withholding or information reporting requirements. 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 2.6(d)(i), (ii) or (iv) below) shall not be required if in such 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. For avoidance of doubt, for the purposes of this Section 2.6(d), the term “Lender” shall include each applicable assignee. Without limiting the generality of the foregoing:

(i)If any Lender is a United States person (as defined in Section 7701(a)(30) of the IRC), such Lender shall deliver, and shall cause each applicable assignee thereof to deliver, to an executed copy of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax.

(ii)If any Lender is a Foreign Lender, such Lender shall deliver, and shall cause each applicable assignee thereof to deliver, to Borrower, on or about the date on which such Foreign Lender becomes a Lender under this Agreement, and at such other times as may be necessary in the determination of Borrower (in the reasonable exercise of its discretion), whichever of the following is applicable:

(1)in the case that such Lender is 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 (including any original issue discount), a properly completed and duly executed copy of IRS Form W-8BEN or IRS Form 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

-8-

(y) with respect to any other applicable payments under any Loan Document, a properly completed and duly executed copy of IRS Form W-8BEN or IRS Form 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;

(2)a completed and duly executed copy of IRS Form W-8ECI;

(3)in the case that such Foreign Lender is claiming an exemption from U.S. federal withholding Tax pursuant to the “portfolio interest exemption” under Section 881(c) of the IRC, it shall provide Borrower with the applicable executed IRS Form W-8BEN-E or IRS Form W-8BEN, as applicable, and a certificate reasonably satisfactory to Borrower to the effect that any interest received by such Foreign Lender is not received by a “bank” on “extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business” within the meaning of Section 881(c)(3)(A) of the IRC, a “10 percent shareholder” of Borrower within the meaning of Section 871(h)(3)(B) of the IRC, or a “controlled foreign corporation” related to Borrower as described in Section 881(c)(3)(C) of the IRC, or

(4)to the extent that such Foreign Lender is not the beneficial owner, an executed copy of IRS Form W-8IMY, accompanied by a withholding statement and IRS Form W-8ECI, IRS Form W-8BEN-E (or W-8BEN, as applicable), IRS Form W-9 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 certificate referenced in Section 2.6(d)(ii)(3) above on behalf of each such direct or indirect partner.

(iii)If any Lender is a Foreign Lender it shall, to the extent it is legally entitled to do so, deliver to Borrower (in such number of copies as shall be requested by the recipient) on or about the date on which it becomes a party to this Agreement (and from time to time thereafter upon the reasonable request of Borrower), executed copies of any other form prescribed by applicable law 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 law to permit Borrower to determine the withholding or deduction required to be made.

(iv)If a payment made to any Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if 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 IRC, as applicable), such Lender shall deliver to Borrower at the time or times prescribed by law and at such time or times reasonably requested by Borrower such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the IRC) and such additional documentation reasonably requested by Borrower as may be necessary for Borrower to comply with their obligations under FATCA and to determine that Lender has complied with its obligations under FATCA or to determine the amount, if any, to deduct and withhold from such payment. Solely for purposes of this clause (iv), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(v)Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or notify Borrower in writing of its legal inability to do so.

(e)If any party hereto determines, in its discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.6 (including by the payment of additional amounts pursuant to this Section 2.6), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, under this Section 2.6 with respect

-9-

to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this clause (e) in the event that such indemnified party 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 indemnified party’s failure to timely provide complete and accurate Internal Revenue Service forms and other documentation required pursuant to Section 2.6(d) or Section 2.8. Notwithstanding anything to the contrary in this clause (e), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (e) if the payment of such amount would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts 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. This clause (e) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(f)[RESERVED].

(g)Borrower shall not be required to compensate a Lender pursuant to this Section for any taxes or related costs suffered more than [***] months prior to the date that such Lender notifies Borrower of such taxes or related costs, and of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such taxes or related costs is retroactive, then the [***]-month period referred to above shall be extended to include the period of retroactive effect thereof).

(h)Tax Status of Borrower. Borrower is currently treated as a corporation for U.S. federal income tax purposes.

(i)Tax Reporting Assistance. Borrower shall use reasonable efforts to assist any Lender (i) in the computation of accruals with respect to any “original issue discount” or “market discount” arising with respect to the Term Loans for U.S. federal income tax purposes, and (ii) with its compliance with any associated tax reporting or filing requirements of such Lender or its partners, members or beneficial owners.

2.7Additional Consideration. As additional consideration for the obligation of each Lender to fund its Applicable Percentage of the Term Loans and the funding of its Applicable Percentage of the Term Loans pursuant to Section 2.2(a) and Section 3.5:

(a)on the Tranche A Closing Date, Borrower shall pay to each Lender an amount equal to the product of (i) such Lender’s Term Loan Commitment, multiplied by (ii) [***] (such product, the “Tranche A Additional Consideration”); and

(b)on the date that is the earlier to occur of (i) the Tranche B Closing Date and (ii) March 31, 2024, Borrower shall pay to each Lender an amount equal to the product of (i) such Lender’s Tranche B Commitment multiplied by (ii) [***] (such product, the “Tranche B Additional Consideration” and, collectively with the Tranche A Additional Consideration, the “Additional Consideration”).

(c)Any and all Additional Consideration shall be fully earned when paid and shall not be refundable for any reason whatsoever and, except as described below, shall be treated as original issue discount with respect to the applicable Term Loan for U.S. federal income tax purposes. The Additional Consideration payable hereunder shall be deducted from the proceeds of the Term Loan to be advanced to Borrower pursuant to Section 2.2(a) and Section 3.5; provided, however, that if the Tranche B Loan does not close on or before March 31, 2024, the Tranche B Additional Consideration shall be due and payable on March 31, 2024 (without deduction from any Term Loan proceeds).

-10-

2.8Note Register; Term Loan Notes.

(a)Note Register. Borrower will maintain at all times at its principal executive office a register that identifies each beneficial owner that is entitled to a payment of principal and stated interest on each Term Loan (the “Note Register”) and provides for the registration and transfer of Term Loan Notes so that each Term Loan is at all times in “registered form” within the meaning of Section 163(f), 871(h)(2) and 881(c)(2) of the IRC and any related regulations (and any other relevant or successor provisions of the IRC or such regulations), including without limitation under United States Treasury Regulations Section 5f.103-1(c) and Proposed Regulations Section 1.163-5 (and any successor provisions), and the provisions of this Agreement shall be construed in a manner that gives effect to such intent. Each Term Loan: (i) shall, pursuant to this clause (a), be registered as to both principal and any stated interest with Borrower or its agent, and (ii) may be transferred or exchanged by any Lender only by surrender of the old instrument at the principal executive office of Borrower (or at the place of payment named in the Term Loan Note, if any), accompanied, if so required by Borrower in the case of a Lender Transfer, by a written instrument of transfer in form reasonably satisfactory to Borrower duly executed by the holder thereof or by such holder’s attorney duly authorized in writing, and Borrower will execute and deliver in exchange therefor a new Term Loan Note or Term Loan Notes, in such denomination(s) as may be requested by such holder, of like tenor and in the same aggregate outstanding principal amount as the aggregate outstanding principal amount of the Term Loan Note(s) so surrendered. Any Term Loan Note issued in exchange for any other Term Loan Note or upon transfer thereof shall carry the rights to unpaid interest and interest to accrue that were carried by the Term Loan Note so exchanged or transferred, and neither gain nor loss of interest shall result from any such transfer or exchange. Any transfer tax or governmental charge relating to such transaction shall be paid by the holder requesting the exchange. The entries in the Note Register shall be conclusive and binding for all purposes, including as to the outstanding principal amount of the Term Loan Note and the payment of interest, principal and other sums due hereunder absent manifest error and Borrower, Lenders and any of their respective agents may treat the Person in whose name any Term Loan Note is registered as the sole and exclusive record and beneficial holder and owner of such Term Loan Note for all purposes whatsoever.

(b)Term Loan Notes. Each Lender shall issue to Borrower, and Borrower shall execute and deliver to each Lender to evidence such Lender’s Term Loan, (i) on the Tranche A Closing Date, a Tranche A Note, and (ii) on the Tranche B Closing Date (if any), a Tranche B Note. All amounts due under the Term Loan Notes shall be repayable as set forth in this Agreement and interest shall accrue on the principal amount of the Term Loans represented by the Term Loan Notes, in each case, in accordance with the terms of this Agreement. All Term Loan Notes shall rank for all purposes pari passu with each other.

4REPRESENTATIONS AND WARRANTIES

In order to induce each Lender and the Collateral Agent to enter into this Agreement and for each Lender to make the Credit Extensions to be made on the applicable Closing Date, each Credit Party, jointly and severally with each other Credit Party, represents and warrants to each Lender and the Collateral Agent that the following statements are true and correct as of each Closing Date (both with and without giving effect to the Term Loans) except as otherwise specified below:

4.1Due Organization, Existence, Power and Authority.

8RIGHTS AND REMEDIES UPON AN EVENT OF DEFAULT

8.1Rights and Remedies. While an Event of Default occurs and continues, the Collateral Agent may, or at the request of the Required Lenders, will, without notice or demand:

(a)declare all Obligations (including, for the avoidance of doubt, any and all amounts payable pursuant to Section 2.2(e) and Section 2.2(f), as applicable) immediately due and payable (but if an Event of Default described in Section 7.5 occurs, all Obligations, including any and all amounts payable pursuant to Section 2.2(e) and Section 2.2(f), as applicable, are automatically and immediately due and payable without any notice, demand or other action by the Collateral Agent or any Lender), whereupon all Obligations for principal, interest, premium or otherwise (including, for the avoidance of doubt, any and all amounts payable pursuant to Section 2.2(e) and Section 2.2(f), as applicable) shall become due and payable by Borrower without presentment for payment, demand, notice of protest or other demand or notice of any kind, which are all expressly waived by the Credit Parties hereby;

(b)stop advancing money or extending credit for Borrower’s benefit under this Agreement;

(c)settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that the Collateral Agent considers advisable, notify any Person owing Borrower money of the Collateral Agent’s security interest, for the benefit of the Lenders and the other Secured Parties, in such funds, and verify the amount of the Collateral Accounts;

(d)make any payments and do any acts it considers necessary or reasonable to protect the Collateral or the Collateral Agent’s security interest, for the benefit of Lenders and the other Secured Parties, in the Collateral. Borrower shall assemble the Collateral if the Collateral Agent or the Required Lenders requests and make it available as the Collateral Agent designates or the Required Lenders designate. The Collateral Agent or its agents or representatives may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien that appears to be prior or superior to its security interest, for the benefit of Lenders and the other Secured Parties, and pay all expenses incurred. Borrower grants the Collateral Agent an irrevocable, royalty-free license or other right to enter, use, operate and occupy (and for its agents or representatives to enter, use, operate and occupy), without charge, any such premises to exercise any of the Collateral Agent’s or any Lender’s rights or remedies under this Section 8.1 (including in order to take possession of, collect, receive, assemble, process, appropriate, remove, realize upon, advertise for sale, sell, assign, license out, convey, transfer or grant options to purchase any Collateral);

(e)apply to the Obligations (i) any balances and deposits of Borrower it holds, (ii) any amount held by the Collateral Agent owing to or for the credit or the account of Borrower or (iii) any balance from any Collateral Account of any Credit Party or instruct the bank at which any such Collateral Account is maintained to pay the balance of any such Collateral Account to the Collateral Agent, for the benefit of Lenders and the other Secured Parties, or to any Lender on behalf of itself and the other Secured Parties, as the Collateral Agent shall direct;

(f)ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. With respect to any and all Intellectual Property owned or held by any Credit Party and included in Collateral, each Credit Party hereby grants to the Collateral Agent, for the benefit of Lenders and the other Secured Parties: (i) an irrevocable, non-exclusive, assignable, royalty-free license or other right to use (and for its agents or representatives to use), without charge, including the right to sublicense, use and practice, any and all such Intellectual Property in order to take possession of, collect, receive, assemble, process, appropriate, remove, realize upon, advertise for sale, sell, assign, license out, convey, transfer or grant options to purchase any Collateral, and access to all media in which any of the licensed items may be recorded or stored and to all Software and programs used for the compilation or printout thereof; and (ii) in connection with the Collateral Agent’s exercise of its rights or remedies under this Section 8.1 (including in order to take possession of, collect, receive, assemble, process, appropriate, remove, realize upon, sell, assign, license out, convey, transfer or grant options to purchase any

-49-

Collateral), each Credit Party’s rights under all licenses and all franchise Contracts inure to the benefit of all Secured Parties;

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

(h)demand and receive possession of the Books of any Credit Party regarding Collateral; and

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

Each of the Collateral Agent and Lender agrees that in connection with any foreclosure or other exercise of rights under this Agreement or any other Loan Document with respect to any Intellectual Property included in the Collateral, the rights of the licensees under any license of such Intellectual Property will not be terminated, limited or otherwise adversely affected so long as no default exists thereunder in a way that would permit the licensor to terminate such license (commonly termed a non-disturbance). Without limitation to any other provision herein or in any other Loan Document, while an Event of Default occurs and continues, at the Collateral Agent’s or the Required Lenders’ request, representatives from Borrower and the Collateral Agent shall promptly meet (in person or telephonically) to discuss in good faith how to collect, receive, appropriate and realize upon Borrower’s rights and interests in, to and under any Company IP Agreement, including in connection with any foreclosure or other exercise of the Collateral Agent’s or any Lender’s rights with respect thereto. If Borrower and the Collateral Agent do not mutually agree with respect thereto within ten (10) Business Days after such request by the Collateral Agent (or such later date as agreed by the Collateral Agent), then the Collateral Agent may request Borrower to, and Borrower (promptly following the receipt of such request) shall, use reasonable best efforts to obtain the written consent of any counterparty to the exercise by the Collateral Agent or any Lender of any and all rights and remedies under this Agreement or any other Loan Document with respect to any Company IP Agreement, in form and substance reasonably satisfactory to the Collateral Agent.

8.2Power of Attorney. Borrower hereby irrevocably appoints the Collateral Agent and any Related Party thereof as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Collateral Accounts directly with depository banks where the Collateral Accounts are maintained, for amounts and on terms the Collateral Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower’s products liability or general liability insurance policies maintained in any jurisdiction regarding Collateral; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of the Collateral Agent or a third party as the Code permits. Borrower hereby appoints the Collateral Agent and any Related Party thereof as its lawful attorney-in-fact to file or record any documents necessary to perfect or continue the perfection of the Collateral Agent’s security interest, for the benefit of Lenders and the other Secured Parties, in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than contingent indemnification obligations to the extent no claim giving rise thereto has been asserted) have been satisfied in full and no Lender is under any further obligation to make Credit Extensions hereunder. The foregoing appointment of the Collateral Agent and any Related Party thereof as Borrower’s attorney in fact, and all of the Collateral Agent’s (or such Related Party’s) rights and powers, coupled with an interest, are irrevocable until all Obligations (other than contingent indemnification obligations to the extent no claim giving rise thereto has been asserted) have been fully repaid and performed and each Lender’s obligation to provide Credit Extensions terminates.

8.3Application of Payments and Proceeds Upon Default. If an Event of Default has occurred and is continuing, the Collateral Agent shall apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Collateral Accounts or disposition of any other Collateral, or otherwise, to the Obligations in such order as the Collateral Agent shall determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Lenders for any deficiency. If the Collateral Agent or any Lender directly or indirectly enters into a deferred payment or other credit

-50-

transaction with any purchaser at any sale of Collateral, the Collateral Agent or such Lender, as applicable, shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by the applicable Lender(s) of cash therefor.

8.4Collateral Agent’s Liability for Collateral. So long as the Collateral Agent complies with Requirements of Law regarding the safekeeping of the Collateral in the possession or under the control of the Collateral Agent the Collateral Agent shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; or (c) any act or default of any other Person. In no event shall the Collateral Agent or any Lender have any liability for any diminution in the value of the Collateral for any reason. Borrower bears all risk of loss, damage or destruction of the Collateral.

8.5No Waiver; Remedies Cumulative. The Collateral Agent’s or any Lender’s failure, at any time or times, to require strict performance by Borrower or any other Person of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of the Collateral Agent or any Lender thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by the party granting the waiver and then is only effective for the specific instance and purpose for which it is given. Each of the Collateral Agent’s and Lender’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Each of the Collateral Agent and Lenders has all rights and remedies provided under the Code, by law, or in equity. The exercise by the Collateral Agent or any Lender of one right or remedy is not an election and shall not preclude the Collateral Agent or any Lender from exercising any other remedy under this Agreement or other remedy available at law or in equity, and the waiver by the Collateral Agent or any Lender of any Event of Default is not a continuing waiver. The Collateral Agent’s or any Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence.

8.6Demand Waiver; Makewhole Amount; Prepayment Premium. Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by the Collateral Agent on which Borrower is liable. Borrower acknowledges and agrees that if the maturity of all Obligations shall be accelerated pursuant to Section 8.1(a) by reason of the occurrence of an Event of Default, the applicable Makewhole Amount and Prepayment Premium that is payable pursuant to Section 2.2(e) and Section 2.2(f), as applicable, shall become due and payable by Borrower upon such acceleration, whether such acceleration is automatic or is effected by the Collateral Agent’s or any Lender’s declaration thereof, as provided in Section 8.1(a), and shall also become due and payable in the event the Obligations are satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure or by any other similar means, and Borrower shall pay the applicable Makewhole Amount and Prepayment Premium that is payable pursuant to Section 2.2(e) and Section 2.2(f), as applicable, as compensation to Lenders for the loss of its investment opportunity and not as a penalty, and Borrower waives any right to object thereto in any voluntary or involuntary bankruptcy, insolvency or similar proceeding or otherwise.

11GENERAL PROVISIONS

11.1Successors and Assigns.

(a)This Agreement binds and is for the benefit of the parties hereto and their respective successors and permitted assigns.

(b)No Credit Party may transfer, pledge or assign this Agreement or any other Loan Document or any rights or obligations hereunder or thereunder without the prior written consent of each Lender. Subject to Section 11.1(d), any Lender may at any time sell, transfer, assign or pledge this Agreement or any other Loan Document or any of its rights or obligations hereunder or thereunder, or grant a participation in all or any part of, or any interest in, such Lender’s obligations, rights or benefits under this Agreement and the other Loan Documents, including with respect to any Term Loan (or any portion thereof), to any other Lender, any Affiliate of any Lender or any third Person without Borrower’s consent (any such sale, transfer, assignment, pledge or grant of a participation, a “Lender Transfer”).

(c)In the case of a Lender Transfer in the form of a participation granted by any Lender to any third party, (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of its obligations hereunder, (iii) Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (iv) any agreement or instrument pursuant to which such Lender sells such participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, restatement, supplement or other modification hereto, in each case subject to the terms and conditions of this Agreement. Borrower agrees that each participant shall be entitled to the benefits of Sections 2.5 and 2.6 (subject to the requirements and limitations therein, including the requirements under Section 2.6(d) (it being understood that the documentation required under Section 2.6(d) shall be delivered to the applicable Lender)) to the same extent as if it were a Person that had acquired its interest by assignment pursuant to clause (b) above; provided that, with respect to any participation, such participant shall not be entitled to receive any greater payment under Sections 2.5 or 2.6 than the applicable Lender (i.e., the party that participated the interest) would have been entitled to receive.

(d)Borrower shall record any Lender Transfer in the Note Register. Each Lender shall provide Borrower and the Collateral Agent with written notice of a Lender Transfer delivered no later than five (5) Business Days prior to the date on which such Lender Transfer is consummated. If any Lender sells a participation, such Lender shall, acting solely for this purpose as a non-fiduciary agent of Borrower, maintain a register complying with the requirements of Sections 163(f), 871(h) and 881(c)(2) of the IRC and the Treasury regulations issued thereunder on which is entered the name and address of each participant and principal amounts (and stated interest) of each participant’s interest in the Term Loans or other obligations under the Loan Documents (the “Participant Register”); provided, however, that such Lender shall have no 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 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 the Code or Treasury Regulations, including without limitation Section 5f.103-1(c) of the United States Treasury Regulations, or is otherwise required thereunder. The entries in the Participant Register shall be conclusive absent manifest error, and the Collateral Agent and each 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.

(e)Any attempted transfer, pledge or assignment of this Agreement or any other Loan Document or any rights or obligations hereunder or thereunder in violation of this Section 11.1 shall be null and void and neither Borrower nor any transfer agent shall give any effect in the Note Register to such attempted transfer.

-54-

11.2Indemnification.

(a)Borrower agrees to indemnify and hold harmless each of the Collateral Agent, Lenders and its and their respective Affiliates (and its or their respective successors and assigns) and each manager, member, partner, controlling Person, director, officer, employee, agent or sub-agent, advisor and affiliate thereof (each such Person, an “Indemnified Person”) from and against any and all Indemnified Liabilities; provided, however, that Borrower shall have no obligation to any Indemnified Person hereunder with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities (i) 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 Indemnified Person (or the gross negligence or willful misconduct of such Indemnified Person’s affiliates or controlling Persons or any of their respective managers, members, partners, controlling Persons, directors, officers, employees, agents or sub-agents, advisors or affiliates), (ii) result from a claim brought by Borrower against an Indemnified Person for material breach in bad faith of any of such Indemnified Person’s obligations hereunder or under any other Loan Document, if Borrower has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction, or (iii) result from a claim not involving an act or omission of Borrower or any of its Subsidiaries that is brought by an Indemnified Person against another Indemnified Person (other than against the Collateral Agent in its capacities as such). This Section 11.2(a) shall not apply with respect to Taxes other than any Taxes that represent liabilities, obligations, losses, damages, penalties, claims, costs, expenses and disbursements arising from any non-Tax claim.

(b)To the extent permitted by Requirements of Law, no party to this Agreement shall assert, and each party to this Agreement hereby waives, any claim against any other party hereto (and its or their successors and assigns), and each manager, member, partner, controlling Person, director, officer, employee, agent or sub-agent, advisor and affiliate thereof, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) (whether or not the claim therefor is based on contract, tort or duty imposed by any applicable legal requirement) arising out of, in connection with, arising out of, as a result of, or in any way related to, this Agreement or any Loan Document or any agreement or instrument contemplated hereby or thereby or referred to herein or therein, the transactions contemplated hereby or thereby, any Credit Extension or the use of the proceeds thereof or any act or omission or event occurring in connection therewith, and each party to this Agreement hereby waives, releases and agrees not to sue upon any such claim or any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

(c)Any action taken by any Credit Party under or with respect to any Loan Document, even if required under any Loan Document or at the request of the Collateral Agent or any Lender, shall be at the expense of such Credit Party, and neither the Collateral Agent, nor any Secured Party shall be required under any Loan Document to reimburse any Credit Party or any Subsidiary of any Credit Party therefor except as expressly provided therein. In addition, and without limiting the generality of Section 2.4, Borrower agrees to pay or reimburse upon demand each of the Collateral Agent and Lenders (and their respective successors and assigns) and each of their respective Related Parties, if applicable, for any and all fees, expenses and disbursements of the kind or nature described in clause (b) of the definition of “Lender Expenses” incurred by it.

11.3Severability of Provisions. In case any provision in or obligation hereunder or under any other Loan Document shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

11.4Correction of Loan Documents. The Collateral Agent or Required Lenders may correct patent errors and fill in any blanks in the Loan Documents consistent with the agreement of the parties hereto so long as the Collateral Agent or Required Lenders, as applicable, provides the Credit Parties and the other parties hereto with written notice of such correction and allows the Credit Parties at least ten (10) days to object to such correction in

-55-

writing delivered to the Collateral Agent and each Lender. In the event of such objection, such correction shall not be made except by an amendment to this Agreement in accordance with Section 11.5.

11.5Amendments in Writing; Integration.

(a)No amendment, restatement or modification of or supplement to any provision of this Agreement or any other Loan Document, or waiver, discharge or termination of any obligation hereunder or thereunder, no approval or consent hereunder or thereunder (including any consent to any departure by Borrower or any other Credit Party herefrom or therefrom), shall in any event be effective unless the same shall be in writing and signed by Borrower (on its own behalf and on behalf of each other Credit Party) and the Required Lenders; provided, however, that no such amendment, restatement, modification, supplement, waiver, discharge, termination, approval or consent shall, unless in writing and signed by the Collateral Agent and the Required Lenders, affect the rights or duties of, or any amounts payable to, the Collateral Agent under this Agreement or any other Loan Document. Any such waiver, approval or consent granted shall be limited to the specific circumstance expressly described in it, and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give rise to, or evidence, any obligation or commitment to grant any further waiver, approval or consent.

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

11.6Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Agreement.

11.7Survival. Termination Prior to Term Loan Maturity Date. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to this Section 11.7 and all Obligations (other than contingent indemnification obligations to the extent no claim giving rise thereto has been asserted and any other obligations which, by their terms, are to survive the termination of this Agreement) have been paid in full and satisfied in accordance with the terms of this Agreement. The obligation of Borrower or any other the Credit Parties in Section 11.2 to indemnify Indemnified Persons shall survive until the statute of limitations with respect to such claim or cause of action shall have run. So long as all Obligations (other than contingent indemnification obligations to the extent no claim giving rise thereto has been asserted and any other obligations which, by their terms, are to survive the termination of this Agreement and for which no claim has been made) have been paid in full and satisfied in accordance with the terms of this Agreement, this Agreement shall be terminated (a) prior to the Term Loan Maturity Date by Borrower, effective five (5) Business Days (or such shorter period as the Collateral Agent may agree in its sole discretion) after written notice of termination is delivered to the Collateral Agent and the Lenders, or (b) if no such notice is delivered, automatically on the Term Loan Maturity Date.

11.8Confidentiality. Any information regarding the Credit Parties and their Subsidiaries and their businesses provided to the Collateral Agent or any Lender by or on behalf of any Credit Party pursuant to the Loan Documents shall be deemed “Confidential Information”; provided, however, that Confidential Information does not include information that is either: (i) in the public domain or in the possession of the Collateral Agent, any Lender or any of their respective Affiliates or when disclosed to the Collateral Agent, any Lender or any of their respective Affiliates, or becomes part of the public domain after disclosure to the Collateral Agent, any Lender or any of their respective Affiliates, in each case, other than as a result of a breach by the Collateral Agent, any Lender or any of their respective Affiliates of the obligations under this Section 11.8; or (ii) disclosed to the Collateral Agent, any Lender or any of their respective Affiliates by a third party if the Collateral Agent, such Lender or such Affiliate, as applicable, does not know (following reasonable inquiry) that the third party is prohibited from disclosing the information. Neither the Collateral Agent nor any Lender shall disclose any Confidential Information to a third party or use Confidential Information for any purpose other than the administration of the Loan Documents, the exercise of its rights or remedies under the Loan Documents or the performance of its duties or obligations under the Loan Documents. The foregoing in this Section 11.8 notwithstanding, the Collateral Agent and each Lender may disclose Confidential Information: (a) to any of its Subsidiaries or Affiliates; (b) to prospective transferees, purchasers or participants of any interest in the Term Loans (including, for the avoidance of doubt, in connection with any proposed

-56-

Lender Transfer); (c) as required by law, regulation, subpoena, or other order, provided, that (x) prior to any disclosure under this clause (c), the Collateral Agent or such Lender, as applicable, agrees to endeavor to provide Borrower with prior written notice thereof, and with respect to any law, regulation, subpoena or other order, to the extent that the Collateral Agent or such Lender is permitted to provide such prior notice to Borrower pursuant to the terms hereof, and (y) any disclosure under this clause (c) shall be limited solely to that portion of the Confidential Information as may be specifically compelled by such law, regulation, subpoena or other order; (d) as the Collateral Agent or any Lender otherwise deems necessary or prudent under Sanctions, Anti-Money Laundering Laws, Anti-Corruption Laws, or Export and Import Laws, provided, that prior to any disclosure under this clause (d), the Collateral Agent or such Lender, as applicable, agrees to endeavor to provide Borrower with prior written notice thereof to the extent practicable, and with respect to any law, regulation, subpoena or other order, to the extent that the Collateral Agent or such Lender is permitted to provide such prior notice to Borrower; (e) to the extent requested by regulators having jurisdiction over the Collateral Agent or such Lender or as otherwise required in connection with the Collateral Agent’s or such Lender’s examination or audit by such regulators (including any self-regulatory authority, such as the National Association of Insurance Commissioners); (f) as the Collateral Agent or such Lender considers reasonably necessary in exercising any rights or remedies under the Loan Documents or in connection with any proceeding relating to the Agreement or any other Loan Documents; (g) to any other party hereto; (h) to third-party service providers of the Collateral Agent or such Lender; and (i) to any of the Collateral Agent’s or such Lender’s Related Parties; provided, however, that the third parties to which Confidential Information is disclosed pursuant to clauses (a), (b), (h) and (i) are bound by obligations of confidentiality and non-use that are no less restrictive than those contained herein. The provisions of this Section 11.8 shall survive the termination of this Agreement.

11.9Attorneys’ Fees, Costs and Expenses. In any action or proceeding between, on the one hand, any Credit Party and, on the other hand, the Collateral Agent or any Lender, arising out of or relating to the Loan Documents other than in connection with the enforcement against any Credit Party of this Agreement or any other Loan Document, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled.

11.10Right of Set-Off. In addition to any rights now or hereafter granted under Requirements of Law and not by way of limitation of any such rights, upon the occurrence of an Event of Default and at any time thereafter during the continuance of any Event of Default, each Lender is hereby authorized by each Credit Party at any time or from time to time, without prior notice to any Credit Party, any such notice being hereby expressly waived by Borrower (on its own behalf and on behalf of each other Credit Party), to set off and to appropriate and to apply any and all deposits (general or special, including Indebtedness evidenced by certificates of deposit, whether matured or unmatured, but not including trust accounts) and any other Indebtedness at any time held or owing by such Lender to or for the credit or the account of any Credit Party against and on account of the obligations and liabilities of any Credit Party to such Lender hereunder and under the other Loan Documents, including all claims of any nature or description arising out of or connected hereto or with any other Loan Document, irrespective of whether or not (a) the Collateral Agent or such Lender shall have made any demand hereunder or (b) the principal of or the interest on the Term Loans or any other amounts due hereunder shall have become due and payable pursuant to Section 2 and although such obligations and liabilities, or any of them, may be contingent or unmatured. Each Lender agrees promptly to notify Borrower and the Collateral Agent after any such set off and application made by such Lender; provided, that the failure to give such notice shall not affect the validity of such set off and application.

11.11Marshalling; Payments Set Aside. Neither the Collateral Agent nor any Lender shall be under any obligation to marshal any assets in favor of any Credit Party or any other Person or against or in payment of any or all of the Obligations. To the extent that any Credit Party makes a payment or payments to any Lender, or the Collateral Agent or any Lender enforces any Liens or exercises its rights of setoff, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver, examiner or any other party under any bankruptcy law, any other state or federal law, common law or any equitable cause, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment or payments had not been made or such enforcement or setoff had not occurred.

11.12Electronic Execution of Documents. The words “execution,” “signed,” “signature,” and words of like import in this Agreement and the other Loan Documents shall be deemed to include electronic signatures or

-57-

electronic records, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any Requirements of Law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

11.13Captions. Section headings herein are included herein for convenience of reference only and shall not constitute a part hereof for any other purpose or be given any substantive effect.

11.14Construction of Agreement. The parties hereto mutually acknowledge that they and their respective attorneys have participated in the preparation and negotiation of this Agreement. In cases of uncertainty, this Agreement shall be construed without regard to which of the parties hereto caused the uncertainty to exist.

11.15Third Parties. Nothing in this Agreement, whether express or implied, is intended to: (a) except as expressly provided in Section 11.2(a), confer any benefits, rights or remedies under or by reason of this Agreement on any Persons other than the express parties to it and their respective successors and permitted assigns; (b) relieve or discharge the obligation or liability of any Person not an express party to this Agreement; or (c) give any Person not an express party to this Agreement any right of subrogation or action against any party to this Agreement. Unless expressly provided to the contrary in this Agreement, a Person who is not a party to this Agreement has no rights under the Contracts (Rights of Third Parties) Act 1999 to enforce or enjoy the benefit of any term of this Agreement. Notwithstanding any term of any Loan Document, the consent of any Person who is not a party to this Agreement is not required to rescind or vary this Agreement at any time.

11.16No Advisory or Fiduciary Duty. The Collateral Agent and each Lender may have economic interests that conflict with those of the Credit Parties. Each Credit Party agrees that nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between any Lender or the Collateral Agent, on the one hand, and such Credit Party, its Subsidiaries, and any of their respective stockholders or affiliates, on the other hand. Each Credit Party acknowledges and agrees that (i) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between each Lender and the Collateral Agent, on the one hand, and such Credit Party, its Subsidiaries and their respective affiliates, on the other hand, (ii) in connection therewith and with the process leading to such transaction, the Collateral Agent and each Lender is acting solely as a principal and not the advisor, agent or fiduciary of such Credit Party, its Subsidiaries or their respective affiliates, management, stockholders, creditors or any other Person, (iii) neither the Collateral Agent nor any Lender has assumed an advisory or fiduciary responsibility in favor of any Credit Party, its Subsidiaries or their respective affiliates with respect to the transactions contemplated hereby or the process leading thereto (irrespective of whether the Collateral Agent or any Lender or any of their respective affiliates has advised or is currently advising such Credit Party, its Subsidiaries or their respective affiliates on other matters) or any other obligation to such Credit Party, its Subsidiaries or their respective affiliates except the obligations expressly set forth in the Loan Documents, and (iv) each Credit Party, its Subsidiaries and their respective affiliates have consulted their own legal and financial advisors to the extent each deemed appropriate. Each Credit Party further acknowledges and agrees that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. Each Credit Party agrees that it will not claim that the Collateral Agent or any Lender has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to such Credit Party, its Subsidiaries or their respective affiliates in connection with such transaction or the process leading thereto.

11.17Credit Parties’ Agent. Each of the Credit Parties hereby irrevocably appoints Borrower, as its agent, attorney-in-fact and legal representative for all purposes, including requesting disbursement of the Term Loans and receiving account statements and other notices and communications to Credit Parties (or any of them) from the Collateral Agent or the Lenders, executing amendments, waivers or other modifications of or supplements to Loan Documents and executing or designating new Loan Documents. The Collateral Agent or the Lenders may rely, and shall be fully protected in relying, on any request for the Term Loans, disbursement instruction, report, information or any other notice or communication made or given by Borrower and any amendment, waiver or other modification of or supplement to a Loan Document or the execution or designation of new Loan Documents executed or made by Borrower, whether in its own name or on behalf of one or more of the other Credit Parties, and the Collateral Agent or the Lenders shall not have any obligation to make any inquiry or request any confirmation from or on behalf of any other Credit Party as to the binding effect on it of any such request, instruction, report, information, other notice,

-58-

communication, amendment, supplement, waiver, other modification, execution or designation, nor shall the joint and several character of the Credit Parties’ obligations hereunder be affected thereby. For all purposes of this Agreement and this Section 11.17 each Swiss Guarantor unconditionally releases the Borrower from any restriction on self-contracting (Selbstkontrahieren) and/or double representation (Doppelvertretung) under Swiss law, both of which are herewith explicitly approved by each Swiss Guarantor.

12COLLATERAL AGENT

12.1Appointment and Authority. Each Lender hereby irrevocably appoints BioPharma Credit PLC to act on its behalf as the Collateral Agent hereunder and under the other Loan Documents and authorizes the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Except for the first two (2) sentences of Section 12.7 and the first sentence and penultimate paragraph of Section 12.9, the provisions of this Section 12 are solely for the benefit of the Collateral Agent and Lenders, and neither Borrower nor any other Credit Party shall have rights as a third party beneficiary of any of such provisions. Subject to Section 12.9 and Section 11.5, any action required or permitted to be taken by the Collateral Agent hereunder shall be taken with the prior approval of the Required Lenders.

12.2Rights as a Lender. The Person serving as the Collateral Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Collateral Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Collateral Agent hereunder in its individual capacity. Such Person and its Affiliates may lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Collateral Agent hereunder and without any duty to account therefor to any Lender.

12.3Swiss Collateral Document. Without limiting any other rights of the Collateral Agent under this Agreement, in relation to the Swiss Security Documents:

(a)the Collateral Agent holds:

(i)any security interest constituted by such Swiss Security Document (but only in relation to an assignment or any other non-accessory (nicht akzessorische) security interest);

(ii)the benefit of this clause (a); and

(iii)any proceeds of such security interest,

as fiduciary (treuhänderisch) in its own name but for the account of all relevant Secured Parties which have the benefit of such security interest in accordance with this Agreement and the respective Swiss Security Documents;

(b)each present and future Secured Party hereby authorizes the Collateral Agent:

(i)acting for itself and in the name and for the account of such Secured Party to accept as its direct representative (direkter Stellvertreter) any Swiss law pledge or any other Swiss law accessory (akzessorische) security interest made or expressed to be made to such Secured Party in relation to the Swiss Security Documents, to hold, administer and, if necessary, enforce any such security interest on behalf of each relevant Secured Party which has the benefit of such security interest;

(ii)to agree as its direct representative (direkter Stellvertreter) to amendments and alterations to any Swiss Security Document which creates a pledge or any other Swiss law accessory (akzessorische) security interest;

(iii)to effect as its direct representative (direkter Stellvertreter) any release of a security interest created under a Swiss Security Document in accordance with this Agreement; and

-59-

(iv)to exercise as its direct representative (direkter Stellvertreter) such other rights granted to the Collateral Agent hereunder or under the relevant Swiss Security Document.

12.4Exculpatory Provisions.

(a)The Collateral Agent shall not have any duties or obligations to the Lenders except those expressly set forth herein and in the other Loan Documents to which it is a party. Without limiting the generality of the foregoing, with respect to the Lenders, the Collateral Agent:

(i)shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing;

(ii)shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents to which it is a party that the Collateral Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in such other Loan Documents), provided that the Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Collateral Agent to liability or that is contrary to any Loan Document or Requirements of Law; and

(iii)shall not, except as expressly set forth herein and in the other Loan Documents to which it is a party, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Credit Party or any of its Affiliates that is communicated to or obtained by the Person serving as the Collateral Agent or any of its Affiliates in any capacity.

(b)The Collateral Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Collateral Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 11.5) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Collateral Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Collateral Agent in writing by Borrower or a Lender.

(c)The Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 3 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Collateral Agent.

12.5Reliance by Collateral Agent. The Collateral Agent 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 (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Collateral Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel (who may be counsel for Borrower), independent accountants, manufacturing consultants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants, consultants or experts.

12.6Delegation of Duties. The Collateral Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Collateral Agent. The Collateral Agent and any such sub-agent may perform any and all of its duties and

-60-

exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section 12 shall apply to any such sub-agent and to the Related Parties of the Collateral Agent and any such sub-agent. The Collateral Agent shall not be responsible for the negligence or misconduct of any sub-agent except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Collateral Agent acted with gross negligence or willful misconduct in the selection of such sub-agent.

12.7Resignation of Collateral Agent. The Collateral Agent may at any time give notice of its resignation to the Lenders and Borrower. Upon the receipt of any such notice of resignation, the Required Lenders shall have the right, with the Borrower’s prior written consent so long as no Default or Event of Default has occurred and is continuing, to appoint a successor; provided, however, that Borrower’s consent shall not be required to the extent the successor is an Affiliate of the Collateral Agent or any Lender (provided that such Collateral Agent shall consult with the Borrower regarding such appointment prior to the effectiveness thereof). 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 that is a Related Party of the Collateral Agent or any Lender; provided that, whether or not a successor has been appointed or has accepted such appointment, such resignation shall become effective upon delivery of the notice thereof. Upon the acceptance of a successor’s appointment as Collateral Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, and the retiring Collateral Agent shall be discharged from all of its duties and obligations under the Loan Documents (if not already discharged therefrom as provided above in this Section 12.7), other than its obligations under Section 11.8. After the retiring Collateral Agent’s resignation, the provisions of this Section 12 and Section 10 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 the retiring Collateral Agent was acting as Collateral Agent. Upon any resignation by the Collateral Agent, all payments, communications and determinations provided to be made by, to or through the Collateral Agent shall instead be made by, to or through each Lender directly, until such time as a Person accepts an appointment as Collateral Agent in accordance with this Section 12.7.

12.8Non-Reliance on Collateral Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Collateral Agent or any other Lender or any of their respective Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and make Credit Extensions hereunder.
