(i)each Lender severally agrees to make, on the Initial Funding Date, an Initial Term Loan to Company in an amount equal to such Lender’s Initial Term Loan Commitment;

(ii)each Lender severally agrees to make, on one occasion during the Delayed Draw A Commitment Period, Delayed Draw A Term Loans to Company in an aggregate amount not to exceed such Lender’s Delayed Draw A Term Loan Commitment;

- 47 -

(iii)each Lender severally agrees to make, on one occasion during the Delayed Draw B Commitment Period, Delayed Draw B Term Loans to Company in an aggregate amount not to exceed such Lender’s Delayed Draw B Term Loan Commitment; and

(iv)at the option of Company, and subject to the approval of Lenders in their sole discretion, each Lender may, severally and not jointly, make Incremental Term Loans to Company in an aggregate amount not to exceed $260,000,000.00.

Company may make only one borrowing under the Initial Term Loan Commitment, which shall be on the Initial Funding Date, and may make only one borrowing under each of the Delayed Draw A Commitment and Delayed Draw B Commitment. Any amount borrowed under this Section 2.1(a) and subsequently repaid or prepaid may not be reborrowed. Subject to Section 2.9, all amounts owed hereunder with respect to the Term Loan shall be paid in full no later than the Term Loan Maturity Date. Each Lender’s Initial Term Loan Commitment, Delayed Draw A Commitment, and Delayed Draw B Commitment shall terminate immediately and without further action on the Credit Date on which such Lender funds Initial Term Loans, Delayed Draw A Term Loans or Delayed Draw B Term Loans, respectively, after giving effect to the funding of such Term Loans on such Credit Date.

(b)Borrowing Mechanics for Term Loans.

(i)Company shall deliver to Administrative Agent a fully executed Funding Notice no later than three Business Days prior to the Initial Funding Date (or such shorter period permitted by Administrative Agent), with respect to Term Loans made on the Initial Funding Date. Following the Initial Funding Date (and subject to the conditions set forth in Section 3.2), whenever Company desires that Lenders make a Delayed Draw Term Loan, Company shall deliver to Administrative Agent a fully executed and delivered Funding Notice no later than 10:00 a.m. (New York City time) at least fifteen (15) U.S. Government Securities Business Days in advance of the proposed Credit Date. Except as otherwise provided herein, a Funding Notice for a Term Loan that is a SOFR Loan shall be irrevocable on and after the related Interest Rate Determination Date, and Company shall be bound to make a borrowing in accordance therewith. Promptly upon receipt by Administrative Agent of any such Funding Notice, Administrative Agent shall notify each Lender of the proposed borrowing. Administrative Agent and Lenders (A) may act without liability upon the basis of written or facsimile notice believed by Administrative Agent in good faith to be from Company (or from any Authorized Officer thereof designated in writing purportedly from Company to Administrative Agent), (B) shall be entitled to rely conclusively on any Authorized Officer’s authority to request a Term Loan on behalf of Company until Administrative Agent receives written notice to the contrary, and (C) shall have no duty to verify the authenticity of the signature appearing on any written Funding Notice.

(ii)Each Lender shall make its applicable Term Loan available to Administrative Agent not later than 12:00 p.m. on the applicable Credit Date, by wire transfer of same day funds in Dollars, at Administrative Agent’s Principal Office. Upon satisfaction or waiver of the conditions precedent specified herein, Administrative Agent shall make the proceeds of the applicable Term Loans available to Company on the applicable Credit Date by causing an amount of same day funds in Dollars equal to the proceeds of all such Loans received by Administrative Agent from Lenders to be credited to the account of Company at Administrative Agent’s Principal Office or to such other account as may be designated in writing to Administrative Agent by Company.

(iii)During the Delayed Draw A Commitment Period, Company may make one (1) draw of Delayed Draw A Term Loans in a minimum amount of $10,000,000 and integral multiples of $5,000,000 in excess of that amount.

- 48 -

(iv)During the Delayed Draw B Commitment Period, Company may make one (1) draw of Delayed Draw B Term Loans in an aggregate minimum amount of $10,000,000 and integral multiples of $5,000,000 in excess of that amount.

(v)With respect to any Funding Notice requesting Incremental Term Loans, (i) the Administrative Agent shall promptly forward such Funding Notice to each Lender and (ii) each Lender shall, within fifteen (15) U.S. Government Securities Business Days of receipt of such Funding Notice, elect or decline to commit, on the applicable Credit Date, to provide its Pro Rata Share of such Term Loans. During such fifteen (15) U.S. Government Securities Business Days period, Borrower shall provide to Administrative Agent, for distribution to the Lenders, such information as reasonably requested by Lenders, including, without limitation any information related to the use of funds of such Incremental Term Loans.

(c)Pro Rata Shares; Availability of Funds.

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

(ii)Availability of Funds. Unless Administrative Agent shall have been notified by any Lender prior to the applicable Credit Date that such Lender does not intend to make available to Administrative Agent the amount of such Lender’s Loan requested on such Credit Date, Administrative Agent may assume that such Lender has made such amount available to Administrative Agent on such Credit Date and Administrative Agent may, in its sole discretion, but shall not be obligated to, make available to Company a corresponding amount on such Credit Date. If such corresponding amount is not in fact made available to Administrative Agent by such Lender, Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with interest thereon, for each day from such Credit Date until the date such amount is paid to Administrative Agent, at the customary rate set by Administrative Agent for the correction of errors among banks for three Business Days and thereafter at the Base Rate. If such Lender does not pay such corresponding amount forthwith upon Administrative Agent’s demand therefor, Administrative Agent shall promptly notify Company and Company shall immediately pay such corresponding amount to Administrative Agent together with interest thereon, for each day from such Credit Date until the date such amount is paid to Administrative Agent, at the rate payable hereunder for Base Rate Loans. Nothing in this Section 2.1(d)(ii) shall be deemed to relieve any Lender from its obligation to fulfill its Term Loan Commitments hereunder or to prejudice any rights that Company may have against any Lender as a result of any default by such Lender hereunder.

Section 2.2Use of Proceeds. The proceeds of the Term Loans shall be applied by Company (a) for the development, promotion and commercial launch of AYVAKIT and BLU-263, (b) to fund potential acquisition and partnership opportunities and (c) for working capital, pipeline research and development and general corporate purposes of Borrower and its Subsidiaries. No portion of the proceeds of the Term Loan shall be used in any manner that causes or might cause such Credit Extension or the application of such proceeds to violate Regulation T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve System or any other regulation thereof or to violate the Exchange Act.

- 49 -

Section 2.3Evidence of Debt; Register; Lenders’ Books and Records; Notes.

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

(b)Register. Administrative Agent shall maintain at its Principal Office a register for the recordation of the names and addresses of Lenders and the principal amount of the Term Loans (and stated interest therein) of each Lender from time to time (the “Register”). The Register shall be available for inspection by Company at any reasonable time and from time to time upon reasonable prior notice. Administrative Agent shall record in the Register the Term Loans (and stated interest thereon), and each repayment or prepayment in respect of the principal amount of the Term Loans, and any such recordation shall be conclusive and binding on Company and each Lender, absent manifest error; provided, failure to make any such recordation, or any error in such recordation, shall not affect Company’s Obligations in respect of any Term Loan. Company hereby designates the entity serving as Administrative Agent to serve as Company’s non-fiduciary agent solely for purposes of maintaining the Register as provided in this Section 2.3, and Company hereby agrees that, to the extent such entity serves in such capacity, the entity serving as Administrative Agent and its officers, directors, employees, agents and affiliates shall constitute “Indemnitees.”

(c)Notes. If so requested by any Lender by written notice to Company (with a copy to Administrative Agent) at least two Business Days prior to the Closing Date, or at any time thereafter, Company shall execute and deliver to such Lender (and/or, if applicable and if so specified in such notice, to any Person who is an assignee of such Lender pursuant to Section 10.6) on the Closing Date (or, if such notice is delivered after the Closing Date, promptly after Company’s receipt of such notice) a Note or Notes.

Section 2.4Interest.

(a)Except as otherwise set forth herein, each Loan shall bear interest on the unpaid principal amount thereof from the date made through repayment (whether by acceleration or otherwise) thereof as follows: (i) if a Base Rate Loan, at the Base Rate plus the Applicable Margin; or (ii) if a SOFR Loan, at Term SOFR plus the Applicable Margin.

(b)The basis for determining the rate of interest with respect to any Loan, and the Interest Period with respect to any SOFR Loan, shall be selected by Company and notified to Administrative Agent and Lenders pursuant to the applicable Funding Notice or Conversion/Continuation Notice, as the case may be. If on any day a Loan is outstanding with respect to which a Funding Notice or Conversion/Continuation Notice has not been delivered to Administrative Agent in accordance with the terms hereof specifying the applicable basis for determining the rate of interest, then for that day such Loan shall be a Base Rate Loan.

(c)In connection with SOFR Loans there shall be no more than five (5) Interest Periods outstanding at any time. In the event Company fails to specify between a Base Rate Loan or a SOFR Loan in the applicable Funding Notice or Conversion/Continuation Notice, such Loan (if outstanding as a SOFR Loan) will be automatically converted into a Base Rate Loan on the last day of the then current Interest Period for such Loan (or if outstanding as a Base Rate Loan will remain as, or (if not then outstanding) will be made as, a Base Rate Loan). At any time that a Default or an Event of Default has

- 50 -

occurred and is continuing, Company no longer shall have the option to request that any portion of the Loans be a SOFR Loan and such SOFR Loans shall automatically convert to Base Rate Loans on the last day of the then current Interest Period. As soon as practicable after 10:00 a.m. (New York City time) on each Interest Rate Determination Date, Administrative Agent shall determine (which determination shall, absent manifest error, be final, conclusive and binding upon all parties) the interest rate that shall apply to the SOFR Loans for which an interest rate is then being determined for the applicable Interest Period and shall promptly give notice thereof (in writing) to Company and each Lender.

(d)Interest payable hereunder shall be computed on the basis of a 360 day year, in each case for the actual number of days elapsed in the period during which it accrues. In computing interest on any Loan, the date of the making of such Loan or the first day of an Interest Period applicable to such Loan or, with respect to a Base Rate Loan being converted from a SOFR Loan, the date of conversion of such SOFR Loan to such Base Rate Loan, as the case may be, shall be included, and the date of payment of such Loan or the expiration date of an Interest Period applicable to such Loan or, with respect to a Base Rate Loan being converted to a SOFR Loan, the date of conversion of such Base Rate Loan to such SOFR Loan, as the case may be, shall be excluded; provided, if a Loan is repaid on the same day on which it is made, one day’s interest shall be paid on that Loan.

(e)Except as otherwise set forth herein, interest on each Term Loan shall be payable in cash and in arrears (i) on each Interest Payment Date and (ii) upon any prepayment of that Term Loan, whether voluntary or mandatory, to the extent accrued on the amount being prepaid.

(f)In connection with the use or administration of Term SOFR, Administrative 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. Administrative Agent will promptly notify Company and the Lenders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR.

Section 2.5Conversion/Continuation.

(a)Subject to Section 2.17 and so long as no Default or Event of Default shall have occurred and then be continuing, Company shall have the option:

(i)to convert at any time all or any part of any Term Loan equal to $5,000,000 and integral multiples of $5,000,000 in excess of that amount from one Type of Loan to another Type of Loan; provided, a SOFR Loan may only be converted on the expiration of the Interest Period applicable to such SOFR Loan unless Company shall pay all amounts due under Section 2.17 in connection with any such conversion; or

(ii)upon the expiration of any Interest Period applicable to any SOFR Loan, to continue all or any portion of such Loan equal to $5,000,000 and integral multiples of $5,000,000 in excess of that amount as a SOFR Loan.

(b)Company shall deliver a Conversion/Continuation Notice to Administrative Agent no later than 10:00 a.m. (New York City time) at least one (1) Business Day in advance of the proposed conversion date (in the case of a conversion to a Base Rate Loan) and at least three (3) Business Days in advance of the proposed conversion/continuation date (in the case of a conversion to, or a continuation of, a SOFR Loan). Except as otherwise provided herein, a Conversion/Continuation Notice for conversion to, or continuation of, any SOFR Loans shall be irrevocable on and after the related Interest Rate Determination Date, and Company shall be bound to effect a conversion or continuation in accordance therewith.

- 51 -

Section 2.6Default Interest. Upon the occurrence and during the continuance of an Event of Default under Sections 8.1(a), (f) or (g), and after notice from the Administrative Agent acting at the direction of the Required Lenders, after the occurrence and during the continuance of any other Event of Default, the principal amount of all Term Loans outstanding and, to the extent permitted by applicable law, any interest payments on the Term Loans or any fees or other amounts owed hereunder (including any Applicable Premium and Prepayment Premium, if applicable), shall thereafter bear interest (including post petition interest in any proceeding under the Bankruptcy Code or other applicable bankruptcy laws) payable on demand at a rate that is [***] per annum in excess of the interest rate otherwise payable hereunder with respect to the Term Loans (the “Default Rate”). All interest payable at the Default Rate shall be payable in cash on demand. Payment or acceptance of the Default Rate of interest provided for in this Section 2.6 is not a permitted alternative to timely payment and shall not constitute a waiver of any Default or Event of Default or otherwise prejudice or limit any rights or remedies of Administrative Agent or any Lender.

Section 2.7Fees.

(a)Company agrees to pay to Administrative Agent all fees payable by it in the Fee Letter in the amounts and at the times specified therein.

(b)All fees referred to in Section 2.7(a) shall be calculated on the basis of a 360 day year and the actual number of days elapsed.

Section 2.8Repayment of Term Loans. The principal amounts of the Term Loans shall be repaid, together with all other amounts owed hereunder with respect thereto, in full in cash no later than the Term Loan Maturity Date.

Section 2.9Voluntary Prepayments and Commitment Reductions.

(a)Voluntary Prepayments.

(i)Subject to the terms of the Fee Letter, Company may prepay at any time the Term Loan on any Business Day in whole or in part (together with any amounts due pursuant to Section 2.19), in an aggregate minimum amount of $5,000,000 and integral multiples of $5,000,000 in excess of that amount.

(ii)All such prepayments shall be made (A) upon not less than one (1) Business Day’s prior written notice in the case of Base Rate Loans and (B) upon not less than three (3) Business Days’ prior written notice in the case of SOFR Loans, in each case given to Administrative Agent by 10:00 a.m. on the date required (and Administrative Agent will promptly transmit such or original notice by facsimile or email to each Lender). Upon the giving of any such notice, the principal amount of the Term Loans specified in such notice shall become due and payable on the prepayment date specified therein. Any such voluntary prepayment shall be applied as specified in Section 2.11(a) with respect to the Term Loans.

(b)Voluntary Commitment Reductions.

(i)Company may, upon not less than three Business Days’ prior written confirmed in writing to Administrative Agent (which written notice Administrative Agent will promptly transmit by facsimile or email to each applicable Lender), at any time and from time to time terminate in whole or permanently reduce in part any unused portion of the Delayed Draw Term Loan Commitments; provided, any such partial reduction of the Delayed Draw Term Loan Commitments shall be in an aggregate minimum amount of $5,000,000 and integral multiples of $5,000,000 in excess of that amount.

- 52 -

(ii)Company’s notice to Administrative Agent shall designate the date (which shall be a Business Day) of such termination or reduction and the amount of any partial reduction, and such termination or reduction of the Delayed Draw Term Loan Commitments shall be effective on the date specified in Company’s notice and shall reduce the Delayed Draw Term Loan of each Lender proportionately to its Pro Rata Share thereof.

Section 2.10Mandatory Prepayments.

(a)Asset Sales.

(i)No later than the [***] following the date of receipt by any Loan Party of any Net Proceeds from Asset Sales (other than any Asset Sale described in clauses (ii) (solely with respect to the GRAVETO Royalty Transaction), (iv), (v), (vi), (vii), (viii), (x) or (xi) of Section 6.9(b)) in excess of [***], Company shall, subject to Section 2.11(b), prepay the Term Loans as set forth in Section 2.11(a) in an aggregate amount equal to such Net Proceeds in excess of [***]; provided, such prepayment shall not be required so long as (i) no Event of Default shall have occurred and be continuing and (ii) Company has delivered Administrative Agent prior written notice of Company’s intention to apply such monies (the “Reinvestment Amounts”) to research, develop, Commercialize or purchase other assets or Products used or useful in the business of the Loan Parties. including capital expenditures, research and development and Permitted Acquisitions, (iii) the Loan Parties complete such reinvestment or purchase within [***] after the initial receipt of such monies, the Loan Parties shall have the option to apply the Reinvestment Amounts to reinvest in or to the costs of purchase of other assets used or useful in the business of the Loan Parties; provided, that if any such Net Proceeds are no longer intended to be or cannot be so reinvested during the applicable [***] period, and subject to Section 2.11(b), an amount equal to any such Net Proceeds shall be applied within [***] after Borrower reasonably determines that such Net Proceeds are no longer intended to be or cannot be so reinvested to the prepayment of the Term Loans as set forth in Section 2.11(a).

(ii)Nothing contained in this Section 2.10(a) shall permit Borrower or any of its Subsidiaries to sell or otherwise dispose of any assets other than in accordance with Section 6.9.

(c)Issuance of Debt. On the date of receipt by Borrower or any of its Subsidiaries of any Cash proceeds from the incurrence of any Indebtedness of Borrower or any of its Subsidiaries (other than with respect to any Indebtedness permitted to be incurred pursuant to Section 6.1), Company shall prepay the Loans in an aggregate amount equal to [***] of such proceeds, net of underwriting discounts

(e)Prepayment Certificate. Concurrently with any prepayment of the Term Loan pursuant to Section 2.10(a) through Section 2.10(c), Company shall deliver to Administrative Agent a certificate of an Authorized Officer demonstrating the calculation of the amount of the applicable net proceeds and compensation owing to Lenders pursuant to the Fee Letter, if any, as the case may be. In the event that Company shall subsequently determine that the actual amount received exceeded the amount set forth in such certificate, Company shall promptly make an additional prepayment of the Loans, and Company shall concurrently therewith deliver to Administrative Agent a certificate of an Authorized Officer demonstrating the derivation of such excess.

Section 2.11Application of Prepayments.

(a)Application of Prepayments of Term Loans. (i) Any prepayment of the Term Loan pursuant to Section 2.9 and (ii) except in connection with any Waivable Mandatory Prepayment provided for in Section 2.11(b), so long as no Application Event has occurred and is continuing, any mandatory prepayment of any Loan pursuant to Section 2.10, in each case, shall be applied as follows:

first, to prepay accrued and unpaid interest on the Term Loan;

second, to pay any Prepayment Premium and any Applicable Premium payable thereon; and

third, to prepay (A) first, the principal of the Initial Term Loan until paid in full and (B) second, the principal of the Delayed Draw Term Loan until paid in full.

(b)Waivable Mandatory Prepayment. Anything contained herein to the contrary notwithstanding, in the event Company is required to make any mandatory prepayment (a “Waivable Mandatory Prepayment”) of the Term Loans pursuant to Section 2.10 (other than Section 2.11(c)), not less than [***] prior to the date (the “Required Prepayment Date”) on which Company is required to make such Waivable Mandatory Prepayment, Company shall notify Administrative Agent of the amount of such prepayment, and Administrative Agent will promptly thereafter notify each Lender holding an outstanding Term Loan of the amount of such Lender’s Pro Rata Share of such Waivable Mandatory Prepayment and such Lender’s option to refuse such amount. Each such Lender may exercise such option by giving written notice to Company and Administrative Agent of its election to do so on or before the first Business Day prior to the Required Prepayment Date (it being understood that any Lender which does not notify Company and Administrative Agent of its election to exercise such option on or before the first Business Day prior to the Required Prepayment Date shall be deemed to have elected, as of such date, not to exercise such option). On the Required Prepayment Date, Company shall pay to Administrative Agent the amount of the Waivable Mandatory Prepayment, which amount shall be applied (i) in an amount equal to that portion of the Waivable Mandatory Prepayment payable to those Lenders that have elected not to exercise such option, to prepay the Term Loans of such Lenders (which prepayment shall be applied in accordance with Section 2.11(a)), and (ii) to the extent of any excess, to Company for working capital and general corporate purposes.

(c)At any time an Application Event has occurred and is continuing, all payments shall be applied pursuant to Section 2.12(f). Nothing contained herein shall modify the provisions of Section 2.12(b) regarding the requirement that all prepayments be accompanied by accrued interest and

- 54 -

fees on the principal amount being prepaid to the date of such prepayment and the applicable Applicable Premium, Prepayment Premium, or any requirement otherwise contained herein to pay all other amounts as the same become due and payable.

Section 2.12General Provisions Regarding Payments.

(a)All payments by Company of principal, interest, fees and other Obligations shall be made in Dollars in immediately available funds, without defense, recoupment, setoff or counterclaim, free of any restriction or condition, and delivered to Administrative Agent, for the account of Lenders, not later than 10:00 a.m. on the date such payment is due and payable to Administrative Agent’s Account. Funds received by Administrative Agent after that time on such due date may be deemed to have been paid by Company on the next Business Day.

(b)All payments in respect of the principal amount of any Term Loan shall be accompanied by payment of accrued interest on the principal amount being repaid or prepaid, any Prepayment Premium, any Applicable Premium, and all other amounts payable with respect to the principal amount being repaid or prepaid.

(c)Administrative Agent shall promptly distribute to each Lender at such address as such Lender shall indicate in writing, such Lender’s applicable Pro Rata Share of all payments and prepayments of principal and interest due hereunder, together with all other amounts due with respect thereto, including, without limitation, all fees payable with respect thereto, to the extent received by Administrative Agent.

(d)Subject to the provisos set forth in the definition of “Interest Period”, whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in the computation of the payment of interest hereunder or of the commitment fees hereunder.

(e)Administrative Agent shall deem any payment by or on behalf of Company hereunder that is not made in same day funds prior to 10:00 a.m. to be a non-conforming payment. Any such payment shall not be deemed to have been received by Administrative Agent until the later of (i) the time such funds become available funds, and (ii) the applicable next Business Day. Administrative Agent shall give prompt telephonic notice to Company and each applicable Lender (confirmed in writing) if any payment is non-conforming. Any non-conforming payment may constitute or become a Default or Event of Default in accordance with the terms of Section 8.1(a). Interest shall continue to accrue on any principal as to which a non-conforming payment is made until such funds become available funds (but in no event less than the period from the date of such payment to the next succeeding applicable Business Day) at the Default Rate determined pursuant to Section 2.6 from the date such amount was due and payable until the date such amount is paid in full.

(f)At any time an Application Event has occurred and is continuing, or the maturity of the Obligations shall have been accelerated pursuant to Section 8.2, all payments or proceeds received by Administrative Agent hereunder or under any Collateral Document in respect of any of the Obligations, including, but not limited to all proceeds received by Administrative Agent in respect of any sale, any collection from, or other realization upon all or any part of the Collateral, shall be applied in full or in part as follows:

first, ratably to pay the Obligations in respect of any fees (other than any Prepayment Premium and Applicable Premium), expense reimbursements, indemnities and other amounts then due and payable to Administrative Agent until paid in full;

- 55 -

second, ratably to pay interest then due and payable in respect of Protective Advances until paid in full;

third, ratably to pay principal of Protective Advances then due and payable until paid in full;

fourth, ratably to pay the Obligations in respect of any fees (other than any Prepayment Premium and Applicable Premium) and indemnities then due and payable to the Lenders with a Term Loan Commitment until paid in full;

fifth, ratably to pay interest then due and payable in respect of the Term Loan until paid in full;

sixth, ratably to pay (A) first, the principal of the Initial Term Loan until paid in full and (B) second, the principal of the Delayed Draw Term Loan until paid in full;

seventh, ratably to pay the Obligations in respect of any Prepayment Premium and Applicable Premium then due and payable to the Lenders with a Term Loan Commitment until paid in full; and

eighth, to the ratable payment of all other Obligations then due and payable until paid in full.

(g)For purposes of Section 2.12(f) (other than clause eighth of Section 2.12(f)), “paid in full” means payment in cash of all amounts owing under the Loan Documents according to the terms thereof, including loan fees, service fees, professional fees, interest (and specifically including interest accrued after the commencement of any Insolvency Proceeding), default interest, interest on interest, and expense reimbursements, whether or not same would be or is allowed or disallowed in whole or in part in any Insolvency Proceeding, except to the extent that default or overdue interest (but not any other interest) and loan fees, each arising from or related to a default, are disallowed in any Insolvency Proceeding; provided, however, that for purposes of clause eighth of Section 2.12(f), “paid in full” means payment in cash of all amounts owing under the Loan Documents according to the terms thereof, including loan fees, service fees, professional fees, interest (and specifically including interest accrued after the commencement of any Insolvency Proceeding), default interest, interest on interest, and expense reimbursements, whether or not the same would be or is allowed or disallowed in whole or in part in any Insolvency Proceeding.

(h)In the event of a direct conflict between the priority provisions of Section 2.12(f) and other provisions contained in any other Loan Document, it is the intention of the parties hereto that both such priority provisions in such documents shall be read together and construed, to the fullest extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, the terms and provisions of Section 2.12(f) shall control and govern.

(i)The Lenders and Company hereby authorize Administrative Agent to, and Administrative Agent may, from time to time, charge the Loan Account with any amount then due and payable by Company under any Loan Document. Each of the Lenders and Company agrees that Administrative Agent shall have the right to make such charges whether or not any Default or Event of Default shall have occurred and be continuing or whether any of the conditions precedent in Section 3.2 have been satisfied. Any amount charged to the Loan Account shall be deemed a Loan hereunder made by the Lenders to Company, funded by Administrative Agent on behalf of the Lenders and subject to Section 2.2. The Lenders and Company confirm that any charges which Administrative Agent may so make to the Loan Account as herein provided will be made as an accommodation to Company and solely at

- 56 -

Administrative Agent’s discretion, provided that Administrative Agent shall from time to time in its discretion or upon the request of the Required Lenders, charge the Loan Account of Company with any amount due and payable under any Loan Document. The Administrative Agent shall provide a reasonably detailed invoice for any amounts charged to the Loan Account (unless such charge is made at the Company’s request) promptly upon request by the Company.

(j)Notwithstanding the foregoing provisions hereof, if any Conversion/Continuation Notice is withdrawn as to any Affected Lender or if any Affected Lender makes Base Rate Loans in lieu of its Pro Rata Share of any SOFR Loans, Administrative Agent shall give effect thereto in apportioning payments received thereafter.

Section 2.13Ratable Sharing. Lenders hereby agree among themselves that, except as otherwise provided in the Collateral Documents with respect to amounts realized from the exercise of rights with respect to Liens on the Collateral, if any of them shall, whether by voluntary payment (other than a voluntary prepayment of Term Loans made and applied in accordance with the terms hereof), through the exercise of any right of set off or banker’s lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents or otherwise, or as adequate protection of a deposit treated as cash collateral under the Bankruptcy Code, receive payment or reduction of a proportion of the aggregate amount of principal, interest, fees and other amounts then due and owing to such Lender hereunder or under the other Loan Documents (collectively, the “Aggregate Amounts Due” to such Lender) which is greater than the proportion received by any other Lender in respect of the Aggregate Amounts Due to such other Lender having Term Loans, then the Lender receiving such proportionately greater payment shall (a) notify Administrative Agent and each other Lender of the receipt of such payment and (b) apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Due to the other Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders having Term Loans in proportion to the Aggregate Amounts Due to them; provided, if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of Company or otherwise, those purchases shall be rescinded and the purchase prices paid for such participations shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. Company expressly consents to the foregoing arrangement and agrees that any holder of a participation so purchased may exercise any and all rights of banker’s lien, set off or counterclaim with respect to any and all monies owing by Company to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder.

Section 2.14Increased Costs; Capital Adequacy.

(a)Compensation For Increased Costs and Taxes. Subject to the provisions of Section 2.15 (which shall be controlling with respect to the matters covered thereby), in the event that Administrative Agent or any Lender shall determine (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto) that any law, treaty or governmental rule, regulation or order, or any change therein or in the interpretation, administration or application thereof (including the introduction of any new law, treaty or governmental rule, regulation or order), or any determination of a court or Governmental Authority, in each case that becomes effective after the date hereof, or compliance by Administrative Agent or such Lender with any guideline, request or directive issued or made after the date hereof by any central bank or other governmental or quasi-Governmental Authority (whether or not having the force of law): (i) subjects Administrative Agent or such Lender (or its applicable lending office) to any additional Tax (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) with respect to this Agreement or any of the other Loan Documents or any of its obligations hereunder or thereunder or any payments to Administrative Agent or such Lender (or its applicable lending office) of

- 57 -

principal, interest, fees or any other amount payable hereunder; (ii) imposes, modifies or holds applicable any reserve (including any marginal, emergency, supplemental, special or other reserve), special deposit, compulsory loan, FDIC insurance or similar requirement against assets held by, or deposits or other liabilities in or for the account of, or advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of Administrative Agent or such Lender (other than any such reserve or other requirements with respect to SOFR Loans that are reflected in the definition of Term SOFR); or (iii) imposes any other condition (other than with respect to Taxes) on or affecting Administrative agent or such Lender (or its applicable lending office) or its obligations hereunder or the London interbank market; and the result of any of the foregoing is to increase the cost to Administrative Agent or such Lender of agreeing to make, making or maintaining Loans hereunder or to reduce any amount received or receivable by Administrative Agent or such Lender (or its applicable lending office) with respect thereto; then, in any such case, Company shall promptly pay to Administrative Agent or such Lender, upon receipt of the statement referred to in the next sentence, such additional amount or amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as Administrative Agent or such Lender in its sole discretion shall determine) as may be necessary to compensate Administrative Agent or such Lender for any such increased cost or reduction in amounts received or receivable hereunder. Administrative Agent or such Lender shall deliver to Company (with a copy to Administrative Agent, if applicable) a written statement, setting forth in reasonable detail the basis for calculating the additional amounts owed to Administrative Agent or such Lender under this Section 2.14(a), which statement shall be conclusive and binding upon all parties hereto absent manifest error.

(b)Capital Adequacy Adjustment. In the event that any Lender shall have determined that the adoption, effectiveness, phase in or applicability after the Closing Date of any law, rule or regulation (or any provision thereof) regarding capital adequacy, or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its applicable lending office) with any guideline, request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of, or with reference to, such Lender’s Term Loans or other obligations hereunder with respect to the Term Loan to a level below that which such Lender or such controlling corporation could have achieved but for such adoption, effectiveness, phase in, applicability, change or compliance (taking into consideration the policies of such Lender or such controlling corporation with regard to capital adequacy), then from time to time, within [***] after receipt by Company from such Lender of the statement referred to in the next sentence, Company shall pay to such Lender such additional amount or amounts as will compensate such Lender or such controlling corporation on an after tax basis for such reduction. Such Lender shall deliver to Company (with a copy to Administrative Agent) a written statement, setting forth in reasonable detail the basis for calculating the additional amounts owed to Lender under this Section 2.14(b), which statement shall be conclusive and binding upon all parties hereto absent manifest error.

Section 2.15Taxes; Withholding, Etc.

(a)Withholding of Taxes. All sums payable by any Loan Party hereunder and under the other Loan Documents shall (except to the extent required by applicable law) be paid free and clear of, and without any deduction or withholding on account of, any Tax. If any Loan Party or any other Person is required by law to make any deduction or withholding on account of any Tax from any sum paid or payable by any Loan Party to Administrative Agent or any Lender under any of the Loan Documents: (1) Company shall notify Administrative Agent of any such requirement or any change in any such requirement as soon as Company becomes aware of it; (2) Company or the applicable Loan Party 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 Loan Party) for its own account or (if that liability is imposed on Administrative Agent or such Lender,

- 58 -

as the case may be) on behalf of and in the name of Administrative Agent or such Lender; (3) if such Tax is an Indemnified Tax, then the sum payable by such Loan Party shall be increased to the extent necessary to ensure that, after the making of that deduction, withholding or payment (including any such deductions, withholdings or payments applicable to additional sums payable under this Section 2.15), Administrative Agent or such Lender, as the case may be, receives on the due date a net sum equal to what it would have received had no such deduction, withholding or payment been required or made; and (4) within [***] after paying any sum from which it is required by law to make any deduction or withholding, Company shall deliver to Administrative Agent evidence satisfactory to Administrative Agent of such deduction, withholding or payment and of the remittance thereof to the relevant Governmental Authority.

(b)Other Taxes. The Loan Parties shall pay to the relevant Governmental Authorities (or, at the option of Administrative Agent, timely reimburse it for the payment of) any present or future stamp, court, documentary, intangible, recording, filing or similar Taxes or any other excise or property Taxes that arise from any payment made hereunder or from the execution, delivery, performance, enforcement or registration of, from the receipt or perfection of a security interest under, or otherwise with respect to, this Agreement or any other Loan Document (“Other Taxes”). Within [***] after paying any such Other Taxes, each Loan Party shall deliver to Administrative Agent evidence satisfactory to Administrative Agent that such Other Taxes have been paid to the relevant Governmental Authority.

(c)Tax Indemnification.

(i)The Loan Parties hereby jointly and severally indemnify and agree to hold Administrative Agent and any Lender harmless from and against all Indemnified Taxes (including, without limitation, Indemnified Taxes imposed or asserted on or attributable to any amounts payable under this Section 2.15) payable or paid by such Person or required to be withheld or deducted from a payment to such Person and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted. Such indemnification shall be paid within [***] from the date on which Administrative Agent or Lender makes written demand therefor. A certificate as to the amount of such payment or liability delivered to Borrower by a Lender (with a copy to Administrative Agent), or by Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(ii)Each Lender shall severally indemnify Administrative Agent, within [***] after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Loan Parties have not already indemnified Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.6(h)(ii) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by Administrative Agent to the Lender from any other source against any amount due to Administrative Agent under this paragraph.

(d)Evidence of Exemption From Withholding Tax.

(i)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 and Administrative Agent, at the time or times reasonably requested by Borrower or the Administrative Agent,

- 59 -

such properly completed and executed documentation reasonably requested by Borrower or Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Borrower or Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by Borrower or Administrative Agent as will enable Borrower or Administrative Agent 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 2.15(d)(i)(A), (i)(B) and (iii)) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Without limiting the generality of the foregoing, in the event that Borrower is a U.S. Borrower.

(A)any Lender that is a U.S. Person shall deliver to Borrower and Administrative Agent on or about the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Borrower or Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

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

(1)in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies 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 (y) with respect to any other applicable payments under any Loan Document, 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)executed copies of IRS Form W-8ECI;

(3)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Internal Revenue Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of Borrower within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation” related to any Loan Party described in Section 881(c)(3)(C) of the Internal Revenue Code Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E; or

(4)to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-

- 60 -

8ECI, IRS Form W-8BEN, IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner;

(ii)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Borrower and Administrative Agent (in such number of copies as shall be requested by the recipient) on or about the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Borrower or Administrative Agent), 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 or Administrative Agent to determine the withholding or deduction required to be made; and

(iii)If a payment made to a Lender under any Loan Document would be subject to United States 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 Internal Revenue Code, as applicable), such Lender shall deliver to Company and Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by Company or Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by Company or Administrative Agent as may be necessary for Company and Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.15(d)(iii), FATCA shall include any amendments made to FATCA after the date of this Agreement. Notwithstanding the above, a Lender shall not be required to deliver any form or other form of documentation pursuant to this Section 2.15(d)(iii) that such Lender is not legally able to deliver.

(e)Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect 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 paragraph (e) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (e), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (e) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph 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.

- 61 -

Section 2.16Obligation to Mitigate. Each Lender agrees that, as promptly as practicable after the officer of such Lender responsible for administering its Term Loans becomes aware of the occurrence of an event or the existence of a condition that would cause such Lender to become an Affected Lender or that would entitle such Lender to receive payments under Section 2.13, 2.14, 2.15 or 2.19, it will, to the extent not inconsistent with the internal policies of such Lender and any applicable legal or regulatory restrictions, use reasonable efforts to (a) make, issue, fund or maintain its Credit Extensions, including any Affected Loans, through another office of such Lender, or (b) take such other measures as such Lender may deem reasonable, if as a result thereof the circumstances which would cause such Lender to be an Affected Lender would cease to exist or the additional amounts which would otherwise be required to be paid to such Lender pursuant to Section 2.13, 2.14, 2.15 or 2.19 would be materially reduced and if, as determined by such Lender in its sole discretion, the making, issuing, funding or maintaining of such Term Loans through such other office or in accordance with such other measures, as the case may be, would not otherwise adversely affect such Term Loans or the interests of such Lender; provided, such Lender will not be obligated to utilize such other office pursuant to this Section 2.16 unless Company agrees to pay all incremental expenses incurred by such Lender as a result of utilizing such other office as described above. A certificate as to the amount of any such expenses payable by Company pursuant to this Section 2.16 (setting forth in reasonable detail the basis for requesting such amount) submitted by such Lender to Company (with a copy to Administrative Agent) shall be conclusive absent manifest error.

Section 2.17Defaulting Lenders. Anything contained herein to the contrary notwithstanding, in the event that any Lender violates any provision of Section 9.5(c), or, other than at the direction or request of any regulatory agency or authority, defaults (in each case, a “Defaulting Lender”) in its obligation to fund (a “Funding Default”) a Term Loan (in each case, a “Defaulted Loan”), then (a) during any Default Period with respect to such Defaulting Lender, such Defaulting Lender shall be deemed not to be a “Lender” for purposes of voting on any matters (including the granting of any consents or waivers) with respect to any of the Loan Documents; and (b) to the extent permitted by applicable law, until such time as the Default Excess, if any, with respect to such Defaulting Lender shall have been reduced to zero, (i) any voluntary prepayment of the Term Loans shall, if Administrative Agent so directs at the time of making such voluntary prepayment, be applied to Term Loans of other Lenders as if such Defaulting Lender had no Term Loans outstanding and the outstanding Term Loans of such Defaulting Lender were zero, and (ii) any mandatory prepayment of the Term Loans shall, if Administrative Agent so directs at the time of making such mandatory prepayment, be applied to the Term Loans of other Lenders (but not to the Term Loans of such Defaulting Lender) as if such Defaulting Lender had funded all Defaulted Loans of such Defaulting Lender, it being understood and agreed that Company shall be entitled to retain any portion of any mandatory prepayment of the Term Loans that is not paid to such Defaulting Lender solely as a result of the operation of the provisions of this clause (b). No Term Loan Commitment of any Lender shall be increased or otherwise affected, and, except as otherwise expressly provided in this Section 2.17, performance by Company of its obligations hereunder and the other Loan Documents shall not be excused or otherwise modified as a result of any Funding Default or the operation of this Section 2.17. The rights and remedies against a Defaulting Lender under this Section 2.17 are in addition to other rights and remedies which Company may have against such Defaulting Lender with respect to any Funding Default and which Administrative Agent or any Lender may have against such Defaulting Lender with respect to any Funding Default or violation of Section 9.5(c).

Section 2.18Removal or Replacement of a Lender. Anything contained herein to the contrary notwithstanding, in the event that: (a) (i) any Lender (an “Increased Cost Lender”) shall give notice to Company that such Lender is an Affected Lender or that such Lender is entitled to receive payments under Section 2.14, 2.15 or 2.16, (ii) the circumstances which have caused such Lender to be an Affected Lender or which entitle such Lender to receive such payments shall remain in effect, and (iii) such Lender shall fail to withdraw such notice within five Business Days after Company’s request for such withdrawal; or (b) (i) any Lender shall become a Defaulting Lender, (ii) the Default Period for such Defaulting Lender shall

- 62 -

remain in effect, and (iii) such Defaulting Lender shall fail to cure the default as a result of which it has become a Defaulting Lender within five Business Days after Company’s request that it cure such default; or (c) in connection with any proposed amendment, modification, termination, waiver or consent with respect to any of the provisions hereof as contemplated by Section 10.5(b), the consent of Administrative Agent and Required Lenders shall have been obtained but the consent of one or more of such other Lenders (each a “Non-Consenting Lender”) whose consent is required shall not have been obtained; then, with respect to each such Increased Cost Lender, Defaulting Lender or Non-Consenting Lender (the “Terminated Lender”), Administrative Agent may (which, in the case of an Increased Cost Lender, only after receiving written request from Company to remove such Increased Cost Lender), by giving written notice to Company and any Terminated Lender of its election to do so, elect to cause such Terminated Lender (and such Terminated Lender hereby irrevocably agrees) to assign its outstanding Term Loans in full to one or more Eligible Assignees (each a “Replacement Lender”) in accordance with the provisions of Section 10.6 and Terminated Lender shall pay any fees payable thereunder in connection with such assignment; provided, (1) on the date of such assignment, the Replacement Lender shall pay to Terminated Lender an amount equal to the sum of (A) an amount equal to the principal of, and all accrued interest on, all outstanding Loans of the Terminated Lender and (B) an amount equal to all accrued, but theretofore unpaid fees owing to such Terminated Lender pursuant to Section 2.7; (2) on the date of such assignment, Company shall pay any amounts payable to such Terminated Lender pursuant to Section 2.14 or 2.15; and (3) in the event such Terminated Lender is a Non-Consenting Lender, each Replacement Lender shall consent, at the time of such assignment, to each matter in respect of which such Terminated Lender was a Non-Consenting Lender. Upon the prepayment of all amounts owing to any Terminated Lender, such Terminated Lender shall no longer constitute a “Lender” for purposes hereof; provided, any rights of such Terminated Lender to indemnification hereunder shall survive as to such Terminated Lender. For the avoidance of doubt, all fees that would otherwise be due and payable to any Non-Consenting Lender, including, without limitation, any Prepayment Premium and any Applicable Premium, shall continue to be due and payable to such Non-Consenting Lender.

Section 2.19Making or Maintaining SOFR Loans.

(a)Inability to Determine Rates. Subject to Section 2.20, if, on or prior to the first day of any Interest Period for any SOFR Loan:

(i)the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof, or

(ii)the Required Lenders determine that for any reason in connection with any request for a SOFR Loan or a conversion thereto or a continuation thereof that Term SOFR for any requested Interest Period with respect to a proposed SOFR Loan does not adequately and fairly reflect the cost to such Lenders of making and maintaining such Loan, and the Required Lenders have provided written notice of such determination to the Administrative Agent, then the Administrative Agent will promptly so notify Company and each Lender.

Upon notice thereof by the Administrative Agent to Company, any obligation of the Lenders to make SOFR Loans, and any right of Company to continue SOFR Loans or to convert Base Rate Loans to SOFR Loans, shall be suspended (to the extent of the affected SOFR Loans or affected Interest Periods) until the Administrative Agent (with respect to clause (b), at the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, (i) Company may revoke any pending request for a borrowing of, conversion to or continuation of SOFR Loans (to the extent of the affected SOFR Loans or affected Interest Periods) or, failing that, Company will be deemed to have converted any such request into a request for a

- 63 -

borrowing of or conversion to Base Rate Loans in the amount specified therein and (ii) any outstanding affected SOFR Loans will be deemed to have been converted into Base Rate Loans at the end of the applicable Interest Period. Upon any such conversion, Company shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to Section 2.19(c). Subject to Section 2.20, if the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof on any given day, the interest rate on Base Rate Loans shall be determined by the Administrative Agent without reference to clause (c) of the definition of “Base Rate” until the Administrative Agent revokes such determination.

(b)Illegality. If any Lender determines that any law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain or fund Loans whose interest is determined by reference to SOFR, the Term SOFR Reference Rate or Term SOFR (the “Affected Loans”), or to determine or charge interest based upon SOFR, the Term SOFR Reference Rate or Term SOFR, then, upon notice thereof by such Lender (an “Affected Lender”) to Company (through the Administrative Agent) (an “Illegality Notice”), (a) any obligation of the Lenders to make SOFR Loans, and any right of Company to continue SOFR Loans or to convert Base Rate Loans to SOFR Loans, shall be suspended, and (b) the interest rate on which Base Rate Loans shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Base Rate”, in each case until each affected Lender notifies the Administrative Agent and Company that the circumstances giving rise to such determination no longer exist. Upon receipt of an Illegality Notice, Company shall, if necessary to avoid such illegality, upon demand from any Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all SOFR Loans to Base Rate Loans (the interest rate on which Base Rate Loans shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Base Rate”), on the last day of the Interest Period therefor, if all affected Lenders may lawfully continue to maintain such SOFR Loans to such day, or immediately, if any Lender may not lawfully continue to maintain such SOFR Loans to such day, in each case until the Administrative Agent is advised in writing by each affected Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon SOFR, the Term SOFR Reference Rate or Term SOFR. Upon any such prepayment or conversion, Company shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 2.19(c).

(c)Compensation for Breakage or Non-Commencement of Interest Periods. Company shall compensate each Lender, upon written request by such Lender (which request shall set forth the basis for requesting such amounts), for all reasonable losses, expenses and liabilities (including any interest paid or calculated to be due and payable by such Lender to lenders of funds borrowed by it to make or carry its SOFR Loans and any loss, expense or liability sustained by such Lender in connection with the liquidation or re-employment of such funds but excluding loss of anticipated profits) which such Lender may sustain: (i) if for any reason (other than a default by such Lender) a borrowing of any SOFR Loan does not occur on a date specified therefor in a Funding Notice, or a conversion to or continuation of any SOFR Loan does not occur on a date specified therefor in a Conversion/Continuation Notice for conversion or continuation; (ii) if any prepayment or other principal payment of, or any conversion of, any of its SOFR Loans occurs on any day other than the last day of an Interest Period applicable to that Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or (iii) if any prepayment of any of its SOFR Loans is not made on any date specified in a notice of prepayment given by Company.

(d)Booking of SOFR Loans. Any Lender may make, carry or transfer SOFR Loans at, to, or for the account of any of its branch offices or the office of an Affiliate of such Lender.

- 64 -

(e)Assumptions Concerning Funding of SOFR Loans. Calculation of all amounts payable to a Lender under this Section 2.19 and under Section 2.14 shall be made as though such Lender had actually funded each of its relevant SOFR Loans through the purchase of a SOFR deposit bearing interest at Term SOFR in an amount equal to the amount of such SOFR Loan and having a maturity comparable to the relevant Interest Period and through the transfer of such SOFR deposit from an offshore office of such Lender to a domestic office of such Lender in the United States of America; provided, however, each Lender may fund each of its SOFR Loans in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 2.19 and under Section 2.14. Anything to the contrary contained herein notwithstanding, neither Administrative Agent, nor any Lender, nor any of their participants, is required actually to match fund any Obligation as to which interest accrues at Term SOFR or the Term SOFR Reference Rate.

Section 2.20Benchmark Replacement Setting.

(a)Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, upon the occurrence of a Benchmark Transition Event, Administrative Agent and Company may amend this Agreement to replace the then-current Benchmark with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5^th) Business Day after Administrative Agent has posted such proposed amendment to all affected Lenders and Company so long as Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders. No replacement of a Benchmark with a Benchmark Replacement pursuant to this Section 2.20(a) will occur prior to the applicable Benchmark Transition Start Date.

(b)Benchmark Replacement Conforming Changes. In connection with the use, administration, adoption or implementation of a Benchmark Replacement, Administrative 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.

(c)Notices; Standards for Decisions and Determinations. Administrative Agent will promptly notify Company and the Lenders of (1) the implementation of any Benchmark Replacement and (2) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Administrative Agent will notify Company of (x) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 2.20(d) and (y) the commencement of any Benchmark Unavailability Period. Any determination, decision or election that may be made by Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 2.20, 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 or any selection, 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 2.20.

(d)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), (1) if the then-current Benchmark is a term rate (including the Term SOFR) and either (I) 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 Administrative Agent in its reasonable discretion or (II) 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

Borrower and its Subsidiaries have not failed to fulfill and perform their obligations which are due under each such Registration, and no event has occurred or condition or state of facts exists which would constitute a breach or default under any such Registration, in each case that would reasonably be expected to cause the revocation, termination or suspension or material limitation of any such Registration, including but not limited to any form of clinical hold order, except as would not reasonably be expected to, individually or in the aggregate, result in Material Regulatory Liabilities.

ARTICLE VII

GUARANTY

Section 7.1Guaranty of the Obligations. Subject to the provisions of Section 7.2, Guarantors jointly and severally hereby irrevocably and unconditionally guaranty for the ratable benefit of the Beneficiaries the due and punctual payment in full of all Obligations when the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. § 362(a)) (collectively, the “Guaranteed Obligations”).

Section 7.2Contribution by Guarantors. All Guarantors desire to allocate among themselves, in a fair and equitable manner, their obligations arising under this Guaranty. Accordingly, in the event any payment or distribution is made on any date by a Guarantor under this Guaranty such that its Aggregate Payments exceeds its Fair Share as of such date, such Guarantor shall be entitled to a contribution from each of the other Guarantors in an amount sufficient to cause each Guarantor’s Aggregate Payments to equal its Fair Share as of such date. “Fair Share” means, with respect to any Guarantor as of any date of determination, an amount equal to (a) the ratio of (i) the Fair Share Contribution Amount with respect to such Guarantor, to (ii) the aggregate of the Fair Share Contribution Amounts with respect to all Guarantors multiplied by, (b) the aggregate amount paid or distributed on or before such date by all Guarantors under this Guaranty in respect of the obligations Guaranteed. “Fair Share Contribution Amount” means, with respect to any Guarantor as of any date of determination, the maximum aggregate amount of the obligations of such Guarantor under this Guaranty that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11 of the United States Code or any comparable applicable provisions of state law; provided, solely for purposes of calculating the “Fair Share Contribution Amount” with respect to any Guarantor for purposes of this Section 7.2, any assets or

- 96 -

liabilities of such Guarantor arising by virtue of any rights to subrogation, reimbursement or indemnification or any rights to or obligations of contribution hereunder shall not be considered as assets or liabilities of such Guarantor. “Aggregate Payments” means, with respect to any Guarantor as of any date of determination, an amount equal to (A) the aggregate amount of all payments and distributions made on or before such date by such Guarantor in respect of this Guaranty (including, without limitation, in respect of this Section 7.2), minus (B) the aggregate amount of all payments received on or before such date by such Guarantor from the other Guarantors as contributions under this Section 7.2. The amounts payable as contributions hereunder shall be determined as of the date on which the related payment or distribution is made by the applicable Guarantor. The allocation among Guarantors of their obligations as set forth in this Section 7.2 shall not be construed in any way to limit the liability of any Guarantor hereunder. Each Guarantor is a third party beneficiary to the contribution agreement set forth in this Section 7.2.

Section 7.3Payment by Guarantors. Subject to Section 7.2, Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which any Beneficiary may have at law or in equity against any Guarantor by virtue hereof, that upon the failure of Company to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. § 362(a)), Guarantors will upon demand pay, or cause to be paid, in Cash, to Administrative Agent for the ratable benefit of Beneficiaries, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for Company’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against Company for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to Beneficiaries as aforesaid.

Section 7.4Liability of Guarantors Absolute. Each Guarantor agrees that its obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Guarantor agrees as follows:

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

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

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

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

- 97 -

not, except to the extent satisfied by such Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of the Guaranteed Obligations;

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

(f)this Guaranty and the obligations of Guarantors hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full in cash of the Guaranteed Obligations), including the occurrence of any of the following, whether or not any Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to events of default) hereof, any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Loan Document or any agreement relating to such other guaranty or security; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Loan Documents or from the proceeds of any security for the Guaranteed Obligations, except to the extent such security also serves as collateral for indebtedness other than the Guaranteed Obligations) to the payment of indebtedness other than the Guaranteed Obligations, even though any Beneficiary might have elected to apply such payment to any part or all of the Guaranteed Obligations; (v) any Beneficiary’s consent to the change, reorganization or termination of the corporate structure or existence of Borrower or any of its Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (vi) any failure to perfect or continue perfection of a security interest in any collateral which secures any of the Guaranteed Obligations; (vii) any defenses, set offs or counterclaims which Company may allege or assert against any Beneficiary in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury; and (viii) any other act or thing or omission,

- 98 -

or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an obligor in respect of the Guaranteed Obligations.

Section 7.5Waivers by Guarantors. Each Guarantor hereby waives, for the benefit of Beneficiaries: (a) any right to require any Beneficiary, as a condition of payment or performance by such Guarantor, to (i) proceed against Company, any other guarantor (including any other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from Company, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any Deposit Account or credit on the books of any Beneficiary in favor of Company or any other Person, or (iv) pursue any other remedy in the power of any Beneficiary whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of Company or any other Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of Company or any other Guarantor from any cause other than payment in full in cash of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon any Beneficiary’s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (iii) any rights to set offs, recoupments and counterclaims, and (iv) promptness, diligence and any requirement that any Beneficiary protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to Company and notices of any of the matters referred to in Section 7.4 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

Section 7.6Guarantors’ Rights of Subrogation, Contribution, Etc. Until the Guaranteed Obligations shall have been indefeasibly paid in cash in full and the Delayed Draw Term Loan Commitments have been terminated, each Guarantor hereby waives any claim, right or remedy, direct or indirect, that such Guarantor now has or may hereafter have against Company or any other Guarantor or any of its assets in connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including without limitation (a) any right of subrogation, reimbursement or indemnification that such Guarantor now has or may hereafter have against Company with respect to the Guaranteed Obligations, (b) any right to enforce, or to participate in, any claim, right or remedy that any Beneficiary now has or may hereafter have against Company, and (c) any benefit of, and any right to participate in, any collateral or security now or hereafter held by any Beneficiary. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full and the Delayed Draw Term Loan Commitments have been terminated, each Guarantor shall withhold exercise of any right of contribution such Guarantor may have against any other guarantor (including any other Guarantor) of the Guaranteed Obligations, including, without limitation, any such right of contribution as contemplated by Section 7.2. Each Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Guarantor may have against Company or against any collateral or security, and any rights of contribution such Guarantor may have against any such other guarantor, shall be

- 99 -

junior and subordinate to any rights any Beneficiary may have against Company, to all right, title and interest any Beneficiary may have in any such collateral or security, and to any right any Beneficiary may have against such other guarantor. If any amount shall be paid to any Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for Administrative Agent on behalf of Beneficiaries and shall forthwith be paid over to Administrative Agent for the benefit of Beneficiaries to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof.

Section 7.7Subordination of Other Obligations. Any Indebtedness of Company or any Guarantor now or hereafter held by any Guarantor is hereby subordinated in right of payment to the Guaranteed Obligations, and any such indebtedness collected or received by such Guarantor after an Event of Default has occurred and is continuing shall be held in trust for Administrative Agent on behalf of the Beneficiaries and, upon demand by the Administrative Agent, shall forthwith be paid over to Administrative Agent for the benefit of Beneficiaries to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of such Guarantor under any other provision hereof.

Section 7.8Continuing Guaranty. This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been indefeasibly paid in full and the Delayed Draw Term Loan Commitments have been terminated. Each Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations.

Section 7.9Authority of Guarantors or Company. It is not necessary for any Beneficiary to inquire into the capacity or powers of any Guarantor or Company or the officers, directors or agents acting or purporting to act on behalf of any of them.

Section 7.10Financial Condition of Company. Any Credit Extension may be made to Company or continued from time to time without notice to or authorization from any Guarantor regardless of the financial or other condition of Company at the time of any such grant or continuation is entered into, as the case may be. No Beneficiary shall have any obligation to disclose or discuss with any Guarantor its assessment, or any Guarantor’s assessment, of the financial condition of Company. Each Guarantor has adequate means to obtain information from Company on a continuing basis concerning the financial condition of Company and its ability to perform its obligations under the Loan Documents, and each Guarantor assumes the responsibility for being and keeping informed of the financial condition of Company and of all circumstances bearing upon the risk of non-payment of the Guaranteed Obligations. Each Guarantor hereby waives and relinquishes any duty on the part of any Beneficiary to disclose any matter, fact or thing relating to the business, operations or conditions of Company now known or hereafter known by any Beneficiary.

Section 7.11Bankruptcy, Etc.

(a)So long as any Guaranteed Obligations remain outstanding, no Guarantor shall, without the prior written consent of Administrative Agent acting pursuant to the instructions of Required Lenders, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against Company or any other Guarantor. The obligations of Guarantors hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, administration, reorganization, liquidation or arrangement of Company or any other Guarantor or by any defense which Company or any other Guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding.

- 100 -

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

(c)In the event that all or any portion of the Guaranteed Obligations are paid by Company, the obligations of Guarantors hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from any Beneficiary as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder.

Section 7.12Discharge of Guaranty Upon Sale of Guarantor. If all of the Capital Stock of any Guarantor or any of its successors in interest hereunder shall be sold or otherwise disposed of (including by merger or consolidation) in accordance with the terms and conditions hereof, the Guaranty of such Guarantor or such successor in interest, as the case may be, hereunder shall automatically be discharged and released without any further action by any Beneficiary or any other Person effective as of the time of such Asset Sale.

(ii)to any Person otherwise constituting an Eligible Assignee with the consent of Company (so long as no Default or Event of Default has occurred and is continuing) (provided, that if Company shall not have responded in writing within [***] after receipt of written notice of the proposed assignment, Company shall be deemed to have approved such assignment) and Administrative Agent; provided, each such assignment pursuant to this Section 10.6(c)(ii) shall be in an aggregate amount of not less than [***] (or such lesser amount as may be agreed to by Company and Administrative Agent).

Each Lender, upon execution and delivery hereof or upon executing and delivering an Assignment Agreement, as the case may be, represents and warrants as of the Closing Date or as of the applicable Effective Date (as defined in the applicable Assignment Agreement) that (i) it is an Eligible Assignee; (ii) it has experience and expertise in the making of or investing in commitments or loans such as the applicable Term Loan Commitments or Loans, as the case may be; (iii) it will make or invest in, as the case may be, its Term Loan Commitments or Loans for its own account in the ordinary course of its business and without a view to distribution of such Term Loan Commitments or Loans within the meaning of the Securities Act or the Exchange Act or other federal securities laws; and (iv) such Lender does not own or control, or own or control any Person owning or controlling, any trade debt or Indebtedness of any Loan Party other than the Obligations or any Capital Stock of any Loan Party.

(g)Effect of Assignment. Subject to the terms and conditions of this Section 10.6, as of the later (i) of the “Effective Date” specified in the applicable Assignment Agreement or (ii) the date such assignment is recorded in the Register: (A) the assignee thereunder shall have the rights and obligations of a “Lender” hereunder to the extent such rights and obligations hereunder have been assigned to it pursuant to such Assignment Agreement and shall thereafter be a party hereto and a “Lender” for all purposes hereof; (B) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned thereby pursuant to such Assignment Agreement, relinquish its rights (other than any rights which survive the termination hereof under Section 10.8) and be released from its obligations hereunder (and, in the case of an Assignment Agreement covering all or the remaining portion of an assigning Lender’s rights and obligations hereunder, such Lender shall cease to be a party hereto; provided, anything contained in any of the Loan Documents to the contrary notwithstanding, such assigning Lender shall continue to be entitled to the benefit of all indemnities hereunder as specified herein with

- 115 -

respect to matters arising out of the prior involvement of such assigning Lender as a Lender hereunder); (C) the Commitments shall be modified to reflect the Commitment of such assignee and any Commitment of such assigning Lender, if any; and (D) if any such assignment occurs after the issuance of any Note hereunder, the assigning Lender shall, upon the effectiveness of such assignment or as promptly thereafter as practicable, surrender its applicable Notes to Administrative Agent for cancellation, and thereupon Company shall issue and deliver new Notes, if so requested by the assignee and/or assigning Lender, to such assignee and/or to such assigning Lender, with appropriate insertions, to reflect the new Commitments and/or outstanding Loans of the assignee and/or the assigning Lender.

(h)Participations.

(i)Each Lender shall have the right at any time to sell one or more participations to any Person (other than Borrower, any of its Subsidiaries or any of its Affiliates) in all or any part of its Commitments, Loans or in any other Obligation. The holder of any such participation, other than an Affiliate of the Lender granting such participation, shall not be entitled to require such Lender to take or omit to take any action hereunder except with respect to any amendment, modification or waiver that would (i) extend the final scheduled maturity of any Term Loan or Note in which such participant is participating, or reduce the rate or extend the time of payment of interest or fees thereon (except in connection with a waiver of applicability of any post default increase in interest rates) or reduce the principal amount thereof, or increase the amount of the participant’s participation over the amount thereof then in effect (it being understood that a waiver of any Default or Event of Default or of a mandatory reduction in the Commitment shall not constitute a change in the terms of such participation, and that an increase in any Term Loan Commitment or Loan shall be permitted without the consent of any participant if the participant’s participation is not increased as a result thereof), (ii) consent to the assignment or transfer by any Loan Party of any of its rights and obligations under this Agreement, or (iii) release all or substantially all of the Collateral under the Collateral Documents or all or substantially all of the Guarantors from the Guaranty (in each case, except as expressly provided in the Loan Documents) supporting the Loans hereunder in which such participant is participating. Company agrees that each participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.19(c) (it being understood that the documentation required under Section 2.15(d) shall be delivered to the participating Lender) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 10.6(c); provided, a participant shall not be entitled to the benefits of Section 2.15 unless, at the time such participant is claiming such benefits, Company is notified of the participation sold to such participant and such participant agrees, for the benefit of Company, to comply with Section 2.15 as though it were a Lender. To the extent permitted by law, each participant also shall be entitled to the benefits of Section 10.4 as though it were a Lender, provided such participant agrees to be subject to Section 2.13 as though it were a Lender.

(ii)In the event that any Lender sells participations in its Commitments, Loans or in any other Obligation hereunder, such Lender shall, acting solely for this purpose as a non-fiduciary agent of Company, maintain a register on which it enters the name and address of all participants in the Commitments, Loans or Obligations held by it and the principal amount (and stated interest thereon) of the portion of such Commitments, Loans or Obligations which are the subject of the participation (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant’s interest in any commitments, loans 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 or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. A Commitment, Loan or Obligation hereunder may be participated in whole or in part only by registration of such participation on the

- 116 -

Participant Register (and each Note shall expressly so provide). The Participant Register shall be available for inspection by Company at any reasonable time and from time to time upon reasonable prior notice. For the avoidance of doubt, Administrative Agent (in its capacity as administrative agent) shall not have any responsibility for maintaining a Participant Register.

(i)Certain Other Assignments. In addition to any other assignment permitted pursuant to this Section 10.6, any Lender or Administrative Agent may assign, pledge and/or grant a security interest in, all or any portion of its Loans, the other Obligations owed by or to such Lender, and its Notes, if any, to secure obligations of such Lender or Administrative Agent or any of its Affiliates to any Person providing any loan, letter of credit or other extension of credit or financial arrangement to or for the account of such Lender or Administrative Agent or any of its Affiliates and any agent, trustee or representative of such Person (without the consent of, or notice to, or any other action by, any other party hereto), including, without limitation, any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve Bank; provided, no Lender or Administrative Agent, as between Company and such Lender or Administrative Agent, shall be relieved of any of its obligations hereunder as a result of any such assignment and pledge; provided further, in no event shall such Person, agent, trustee or representative of such Person or the applicable Federal Reserve Bank be considered to be a “Lender” or “Agent” or be entitled to require the assigning Lender or Administrative Agent to take or omit to take any action hereunder.

Section 10.7Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default if such action is taken or condition exists.

Section 10.8Survival of Representations, Warranties and Agreements. All representations, warranties and agreements made herein shall survive the execution and delivery hereof and the making of any Credit Extension. Notwithstanding anything herein or implied by law to the contrary, the agreements of each Loan Party set forth in Sections, 2.14, 2.15, 2.19(c), 10.2, 10.3, 10.4, and 10.10 and the agreements of Lenders set forth in Section 2.13, 9.3(b) and 9.6 shall survive the payment of the Term Loans and the termination hereof.

Section 10.9No Waiver; Remedies Cumulative. No failure or delay on the part of Administrative Agent or any Lender in the exercise of any power, right or privilege hereunder or under any other Loan Document shall impair such power, right or privilege or be construed to be a waiver of any default or acquiescence therein, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other power, right or privilege. The rights, powers and remedies given to Administrative Agent and each Lender hereby are cumulative and shall be in addition to and independent of all rights, powers and remedies existing by virtue of any statute or rule of law or in any of the other Loan Documents. Any forbearance or failure to exercise, and any delay in exercising, any right, power or remedy hereunder shall not impair any such right, power or remedy or be construed to be a waiver thereof, nor shall it preclude the further exercise of any such right, power or remedy.

Section 10.10Marshalling; Payments Set Aside. Neither Administrative Agent nor any Lender shall be under any obligation to marshal any assets in favor of any Loan Party or any other Person or against or in payment of any or all of the Obligations. To the extent that any Loan Party makes a payment or payments to Administrative Agent or Lenders (or to Administrative Agent, on behalf of Lenders), or Administrative Agent or Lenders enforce any security interests or exercise their rights of setoff, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee,

- 117 -

receiver or any other party under any bankruptcy law, any other state or federal law, common law or any equitable cause, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment or payments had not been made or such enforcement or setoff had not occurred.

Section 10.11Severability. In case any provision in or obligation hereunder or any Note or 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.

Section 10.12Obligations Several; Independent Nature of Lenders’ Rights. The obligations of Lenders hereunder are several and no Lender shall be responsible for the obligations or Commitment of any other Lender hereunder. Nothing contained herein or in any other Loan Document, and no action taken by Lenders pursuant hereto or thereto, shall be deemed to constitute Lenders as a partnership, an association, a joint venture or any other kind of entity. The amounts payable at any time hereunder to each Lender shall be a separate and independent debt, and, subject to Section 9.8, each Lender shall be entitled to protect and enforce its rights arising under this Agreement and the other Loan Documents and it shall not be necessary for any other Lender to be joined as an additional party in any proceeding for such purpose.

Section 10.13Contingent Payment Debt Instrument Rules. The parties hereto agree (i) that any contingency associated with the Term Loans is described in Treasury Regulations Section 1.1272-1(c) and/or Treasury Regulations Section 1.1275-2(h), and therefore no Term Loan is governed by the rules set out in Treasury Regulations Section 1.1275-4, (ii) except for a Lender described in Sections 871(h)(3) or 881(c)(3) of the Internal Revenue Code, absent a change in law, all interest on the Term Loans is “portfolio interest” within the meaning of Sections 871(h) or 881(c) of the Internal Revenue Code, and therefore is exempt from withholding tax under Sections 1441(c)(9) and 1442(a) of the Internal Revenue Code, and (iii) to adhere to this Section 10.13 for U.S. federal income and any other applicable Tax purposes and not to take any action or file any Tax return, report or declaration inconsistent herewith unless otherwise required by applicable law.

Section 10.14Original Issue Discount. For purposes of Sections 1272, 1273 and 1275 of the Internal Revenue Code, each Term Loan is being issued with original issue discount; please contact Michael Landsittel (MLandsittel@blueprintmedicines.com) to obtain information regarding the issue price, the amount of original issue discount and the yield to maturity.

Section 10.19Confidentiality. Administrative Agent and Lender shall hold all non-public information regarding Company and its Subsidiaries and their businesses identified as such by Company and obtained by such Lender from Company or its Subsidiaries pursuant to the requirements hereof in accordance with such Lender’s customary procedures for handling confidential information of such nature, it being understood and agreed by Company that, in any event, Administrative Agent or Lender may make (i) disclosures of such information to Affiliates of Administrative Agent or Lender and to their agents, advisors, directors, officers, and shareholders (and to other persons authorized by a Lender or Administrative Agent to organize, present or disseminate such information in connection with disclosures otherwise made in accordance with this Section 10.19), (ii) disclosures of such information reasonably required by any bona fide or potential assignee, transferee or participant in connection with the contemplated assignment, transfer or participation by any such Lender of any Loans or any participations therein, (iii) disclosure to any rating agency when required by it, (iv) disclosure to any Lender’s financing sources, provided that prior to any disclosure, such financing source is informed of the confidential nature of the information, (v) disclosures of such information to any actual or potential investors, members, and partners of Administrative Agent any Lender or their Affiliates, provided that prior to any disclosure, such investor or partner is informed of the confidential nature of the information, and (vi) disclosure required or requested in connection with any public filings, whether pursuant to any securities laws or regulations or rules promulgated therefor (including the Investment Company Act of 1940 or otherwise) or representative thereof or by the National Association of Insurance Commissioners (and any successor thereto) or pursuant to legal or judicial process; provided, unless specifically prohibited by applicable law or court order, Administrative Agent and Lender shall make reasonable efforts to notify Company of any request by any Governmental Authority or representative thereof (other than any such request in connection with any examination of the financial condition or other routine examination of such Lender by such Governmental Authority) for disclosure of any such non-public information prior to disclosure of such information. Notwithstanding anything to the contrary set forth herein, each party (and each of their respective employees, representatives or other agents) may disclose to any and all persons, without limitations of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions and other tax analyses) that are provided to any such party relating to such tax treatment and tax structure. However, any information relating to the tax treatment or tax structure shall remain subject to the confidentiality provisions hereof (and the foregoing sentence shall not apply) to the extent reasonably necessary to enable the parties hereto, their respective Affiliates, and their and their respective Affiliates’ directors and employees to comply with applicable securities laws. For this purpose, “tax structure” means any facts relevant to the federal income tax treatment of the transactions contemplated by this Agreement but does not include information relating to the identity of any of the parties hereto or any of their respective Affiliates. Notwithstanding the foregoing, on or after the Closing Date, Administrative Agent and any Lender may, at its own expense, issue news releases and publish “tombstone” advertisements and other announcements relating to this transaction in newspapers, trade journals and other appropriate media (which may include use of logos of one or more of the Loan Parties) (collectively, “Trade Announcements”).

Section 10.20Usury Savings Clause. Notwithstanding any other provision herein, the aggregate interest rate charged or agreed to be paid with respect to any of the Obligations, including all charges or fees in connection therewith deemed in the nature of interest under applicable law shall not exceed the Highest Lawful Rate. If the rate of interest (determined without regard to the preceding sentence) under this Agreement at any time exceeds the Highest Lawful Rate, the outstanding amount of the Loans made hereunder shall bear interest at the Highest Lawful Rate until the total amount of interest due hereunder equals the amount of interest which would have been due hereunder if the stated rates of interest set forth in this Agreement had at all times been in effect. In addition, if when the Loans made hereunder are repaid in full the total interest due hereunder (taking into account the increase provided for above) is less than the total amount of interest which would have been due hereunder if the stated rates of interest set forth in this Agreement had at all times been in effect, then to the extent permitted by law, Company shall pay to Administrative Agent an amount equal to the difference between the amount of interest paid and the amount of interest which would have been paid if the Highest Lawful Rate had at all times been in effect. Notwithstanding the foregoing, it is the intention of Lenders and Company to conform strictly to any applicable usury laws. Accordingly, if any Lender contracts for, charges, or receives any consideration which constitutes interest in excess of the Highest Lawful Rate, then any such excess shall be cancelled automatically and, if previously paid, shall at such Lender’s option be applied to the outstanding amount of the Loans made hereunder or be refunded to Company. In determining whether the interest contracted for, charged, or received by Administrative Agent or a Lender exceeds the Highest Lawful Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest, throughout the contemplated term of the Obligations hereunder.

Section 10.21Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument. This Agreement shall become effective upon the execution of a counterpart hereof by each of the parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic imaging means shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “execute”, “signed,” “signature,” and words of like import in or related to any document to be signed in connection with this Agreement and the other Loan Documents and the transactions contemplated hereby and thereby (including without limitation Assignment Agreement, amendments, Notices, waivers and consents) shall be deemed to include electronic signatures, the electronic matching of assignment terms and contract formations on electronic platforms approved by Administrative Agent, or the keeping of records in electronic form, 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 applicable 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.

Section 10.22Effectiveness. This Agreement shall become effective upon the execution of a counterpart hereof by each of the parties hereto and receipt by Company and Administrative Agent of written notification of such execution and authorization of delivery thereof.

Section 10.23PATRIOT Act Notice. Each Lender and Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Loan Parties that pursuant to the requirements of the PATRIOT Act, it may be required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of the Loan Parties and other information that will allow such Lender or Administrative Agent, as applicable, to identify the Loan Parties in accordance with the PATRIOT Act or other Anti-Terrorism Laws of the Loan Parties and other information that will allow such
