 1.    ACCOUNTING AND OTHER TERMS

2.    LOAN AND TERMS OF PAYMENT 

2.1    Promise to Pay. Each Borrower hereby unconditionally promises to pay each Lender, ratably, the
outstanding principal amount of all Loans, accrued and unpaid interest, fees and charges thereon and to pay all Obligations as and when due in accordance with this Agreement. 

2.2    Availability and Repayment of the Loans. 

(a)    Availability. 

(i)    Subject to the terms and conditions of this Agreement, each Lender agrees, severally and not jointly, to make to
Borrowers an advance on the Closing Date in principal amount equal to its First Tranche Term Loan Commitment (the “First Tranche Term Loans”). Lenders’ commitments to make the First Tranche Term Loans shall terminate upon the
funding of the First Tranche Term Loans on the Closing Date. 
 (ii)    Subject to the terms and conditions of this
Agreement, each Lender agrees, severally and not jointly, to make to Borrowers an advance during the Second Tranche Availability Period in principal amount equal to its Second Tranche Term Loan Commitment (the “Second Tranche Term
Loans”). Lenders’ commitments to make the Second Tranche Term Loans shall terminate upon the earlier of (i) the end of the Second Tranche Availability Period, and (ii) the date the Second Tranche Term Loans have been funded.













 (iii)    Subject to Lenders’ approval in each Lender’s sole
and absolute discretion and the terms and conditions of this Agreement, each Lender may, severally and not jointly, make to Borrowers an advance during the Third Tranche Availability Period in principal amount equal to its Third Tranche Term Loan
Commitment (the “Third Tranche Term Loans”, and together with the First Tranche Term Loan, and the Second Tranche Term Loan, collectively, the “Term Loans”, and each, a “Term Loan”). No Third
Tranche Term Loans shall be made after the earlier of (i) the end of the Third Tranche Availability Period, and (ii) the date that Third Tranche Term Loans have been funded. 

Borrowers shall use the proceeds of the Term Loans (i) to repay existing outstanding Indebtedness of Borrower Representative owing to
Perceptive Credit Holdings II, LP, and (ii) for working capital and general corporate purposes. Once repaid, the Term Loans may not be reborrowed. 

(b)    Repayment. Commencing on the Amortization Date, and continuing thereafter on each Payment Date through the
Term Loan Maturity Date, Borrowers shall make consecutive monthly payments of equal principal and interest, which would fully amortize the principal amount of the Term Loans and accrued interest thereon by the Term Loan Maturity Date, provided that
if the Applicable Rate is adjusted or the Amortization Date is extended in accordance with its terms, the amortization schedule and the required monthly installment shall be recalculated based on the adjusted Applicable Rate and/or the adjusted
number of Payment Dates through the Term Loan Maturity Date. Any and all unpaid Obligations, including principal and accrued and unpaid interest in respect of the Term Loans, the fees pursuant to the Fee Letter and any other fees and other sums due
hereunder, if any, shall be due and payable in full on the Term Loan Maturity Date. The Term Loans may only be prepaid in accordance with Sections 2.2(c) or (d). 

(c)    Mandatory Prepayment Upon an Acceleration. If the Loans are accelerated in accordance with the terms hereof
following the occurrence and during the continuation of an Event of Default, Borrowers shall immediately pay to Lenders, an amount equal to the sum of: 

(i)    all outstanding principal plus accrued and unpaid interest thereon, plus 

(ii)    all amounts then due in accordance with the Fee Letter, plus 

(iii)    all other sums, if any, that shall have become due and payable, including interest at the Default Rate with
respect to any past due amounts. 
 (d)    Permitted Prepayment of Loans. Borrowers shall have the option to
prepay all, but not less than all, of the Loans, provided Borrowers provide written notice to Administrative Agent of its election to prepay the Loans at least fifteen (15) days prior to such prepayment (it being understood and agreed that any
such prepayment may be made conditional upon the occurrence of a “change of control” or a refinancing of the Obligations), and pay, on the date of such prepayment, to Lenders, ratably, an amount equal to the sum of: 

(i)    all outstanding principal plus accrued and unpaid interest thereon, plus 

(ii)    all amounts then due in accordance with the Fee Letter, plus 

(iii)    all other sums, if any, that shall have become due and payable, including interest at the Default Rate with
respect to any past due amounts. 
 2.3    Payment of Interest. 

(a)    Interest Rate. Subject to Section 2.3(b), the outstanding principal amount of the
Loans shall accrue interest from and after its Funding Date, at the Applicable Rate, and Borrowers shall pay such interest monthly in arrears on each Payment Date commencing on July 1, 2020. 

(b)    Default Rate. Immediately upon the occurrence and during the continuation of an Event of Default,
Obligations shall bear interest at a rate per annum which is five percentage points (5.0%) above the rate that is otherwise applicable thereto (the “Default Rate”). Fees and expenses which are required to be paid by Borrowers
pursuant to the Loan Documents (including, without limitation, Lender Expenses) but are not paid when 

  
 2 













 
due shall bear interest until paid at a rate equal to the highest rate applicable to the Obligations. Payment or acceptance of the increased interest rate provided in this
Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies pursuant to the Loan Documents. Each Borrower
agrees that interest at the Default Rate is a reasonable calculation of Lenders’ lost profits in view of the difficulties and impracticality of determining actual damages resulting from an Event of Default. 

(c)    Payment; Interest Computation. Interest is payable monthly in arrears on the Payment Date of the following
month and shall be computed on the basis of a 360-day year for the actual number of days elapsed. In computing interest, (i) all payments received after 3:00 p.m. Eastern Time on any day
shall be deemed received at the opening of business on the next Business Day, and (ii) the date of the making of any Loan shall be included and the date of payment shall be excluded. Changes to the Applicable Rate based on changes to the Prime
Rate, shall be effective as of the date, and to the extent, of such change. 
 (d)    Maximum Interest.
Notwithstanding any provision in this Agreement or any other Loan Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent
jurisdiction shall deem applicable hereto (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that a Borrower has actually paid to or for the benefit of Lenders an amount of interest in excess of the
amount that would have been payable if all of the Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrowers shall be applied as follows: first, to the payment of principal outstanding in
respect of the Loans; second, after all principal is repaid, to the payment of accrued interest, third, to the payment of Lender Expenses and any other Obligations; and fourth, after all Obligations are repaid, the excess (if any) shall be refunded
to Borrowers or paid to whomsoever may be legally entitled thereto, provided that amounts payable to Lenders, shall be paid ratably. 

2.4    Fees and Charges. Borrowers shall pay to Administrative Agent, for the ratable benefit of Lenders:

 (a)    Fees. The fees and charges as and when due in accordance with the Fee Letter; and 

(b)    Expenses. All Lender Expenses incurred through and after the Closing Date, when due (or, if no stated due
date, within two (2) Business Days after demand by Administrative Agent). 
 2.5    Payments; Application
of Payments; Automatic Payment Authorization; Withholding. 
 (a)    All payments to be made by Borrowers under any
Loan Document, including payments of principal and interest and all fees, charges, expenses, indemnities and reimbursements, shall be made in immediately available funds in Dollars, without setoff, recoupment or counterclaim, before 3:00 p.m.
Eastern Time on the date when due. Payments of principal and/or interest received after 3:00 p.m. Eastern Time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day,
the payment shall be due the next Business Day, and additional fees or interest, as applicable, shall continue to accrue until paid. 

(b)    No Borrower shall have a right to specify the order or the loan accounts to which a Lender shall allocate or apply
any payments made by a Borrower to or for the benefit of such Lender or otherwise received by such Lender under this Agreement when any such allocation or application is not expressly specified elsewhere in this Agreement. 

(c)    Administrative Agent, on behalf of Lenders, may initiate debit entries to any Deposit Accounts as authorized on the
Automatic Payment Authorization for principal and interest payments or any other Obligations when due. These debits shall not constitute a set-off. If the ACH payment arrangement is terminated for any reason,
Borrowers shall make all payments due hereunder at the applicable address specified in Section 10, or as otherwise notified by Administrative Agent in writing. 

(d)    Borrowers, Administrative Agent, Collateral Trustee and each Lender hereby agree to the terms and conditions set
forth on Schedule 3 hereto. 
 2.6    Promissory Notes. Borrowers agree that: (a) upon written
notice by or on behalf of any Lender to Borrowers that a promissory note or other evidence of indebtedness is requested by such Lender to evidence the Loans 

  
 3 













 
and other Obligations owing or payable to, or to be made by, such Lender, Borrowers shall promptly (and in any event within three (3) Business Days of any such request) execute and deliver
to such Lender an appropriate promissory note, in substantially the form attached hereto as Exhibit G, and (b) upon any Lender’s written request, and in any event within three (3) Business Days of any such request, the
Borrowers shall execute and deliver to such Lender new notes and/or divide the notes in exchange for then existing notes in such smaller amounts or denominations as such Lender shall specify in its sole and absolute discretion; provided, that
the aggregate principal amount of such new notes shall not exceed the aggregate principal amount of the applicable Loans made by such Lender; provided, further, that such promissory notes that are to be replaced shall then be deemed no
longer outstanding hereunder and replaced by such new notes and returned to the Borrowers within a reasonable period of time after such Lender’s receipt of the replacement notes. Regardless whether or not any such promissory notes are issued,
this Agreement shall evidence the Loans and other Obligations owing or payable by Borrowers to each Lender. 

3.    CONDITIONS OF LOANS 

3.1    Conditions Precedent to Initial Loan. Each Lender’s obligation to make the initial Loan is
subject to the condition precedent that Lender shall have received, in form and substance satisfactory to Administrative Agent, such documents, and completion of such other matters, as Administrative Agent may reasonably deem necessary or

met. 
 3.3    Covenant to Deliver. 

(a)    Loan Parties agree to deliver each item required to be delivered under this Agreement as a condition precedent to
any Loan. Loan Parties expressly agree that a Loan made prior to the receipt of any such item shall not constitute a waiver by Administrative Agent of a Borrower’s obligation to deliver such item, and the making of any Loan in the absence of a
required item shall be in Administrative Agent’s sole discretion. 
 (b)    Loan Parties agree to deliver the items

Representative shall deliver a completed Loan Request to Administrative Agent (which may be delivered by email) no later than 3:00 p.m. Eastern Time, ten (10) Business Days prior to the date such Loan is requested to be made. On the Funding
Date, each applicable Lender shall fund the applicable Loan in the manner requested by the Loan Request, provided that each of the conditions precedent to such Loan is satisfied. 

4.    CREATION OF SECURITY INTEREST  

4.1    Grant of Security Interest. Each Loan Party hereby grants to Collateral Trustee, for the ratable
benefit of Lenders, to secure the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to Collateral Trustee, the Collateral, wherever located, whether now owned or hereafter acquired or arising,
and all proceeds and products thereof. If this Agreement is terminated, Collateral Trustee’s Lien in the Collateral shall continue until the Obligations (other than contingent indemnification obligations as to which no claim has been asserted
or is known to exist) are repaid in full in cash. 
 4.2    Priority of Security Interest. Each Loan Party
represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens). If a Loan Party shall acquire a
commercial tort claim with a potential recovery in excess of $500,000, such Loan Party shall promptly notify Administrative Agent in writing and deliver such other information and documents as Administrative Agent may reasonably require to take any
further action necessary or advisable to perfect Collateral Trustee’s Lien in such commercial tort claim. If a Loan Party shall acquire any instrument with a value in excess of $500,000, such Loan Party shall promptly notify Administrative
Agent and deliver the same in original together with an allonge or other appropriate instrument of transfer and any necessary endorsement, all in form reasonably satisfactory to Collateral Trustee. 

4.3    Authorization to File Financing Statements. Each Loan Party hereby authorizes Collateral Trustee or
its designee (or the Administrative Agent, on behalf of the Collateral Trustee) to file at any time financing statements, continuation statements and amendments thereto with all appropriate jurisdictions to perfect or protect Collateral
Trustee’s interest or rights hereunder. 
 4.4    Pledge of Collateral. Each Loan Party hereby
pledges, assigns and grants to Collateral Trustee a security interest in the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or
granted in connection therewith, and all other cash and noncash proceeds of the foregoing, as security for the performance of the Obligations. On the Closing Date or to the extent any Shares pledged hereunder from time to time are or become
certificated and such Shares either (i) represent Equity Interests of a Subsidiary or (ii) have a value in excess of $500,000, and in each case, the extent the same constitute Collateral, such certificates shall be delivered to Collateral
Trustee, accompanied by a stock power 

  
 5 













 
or other appropriate instrument of assignment duly executed in blank. To the extent required by the terms and conditions governing the Equity Interests in which a Loan Party has an interest, such
Loan Party shall cause the books of each Person whose Equity Interests are part of the Collateral and any transfer agent to reflect the pledge of the Equity Interests. Upon the occurrence and during the continuation of an Event of Default hereunder,
Collateral Trustee may effect the transfer of any securities included in the Collateral (including but not limited to the Equity Interests) into the name of Collateral Trustee and cause new certificates representing such securities to be issued in
the name of Collateral Trustee or its transferee. Each Loan Party will execute and deliver such documents, and take or cause to be taken such actions, as Administrative Agent may reasonably request to perfect or continue the perfection of Collateral
Trustee’s security interest in the Equity Interests. Each Loan Party shall be entitled to exercise any voting rights with respect to the Equity Interests in which it has an interest and to give consents, waivers and ratifications in respect
thereof, unless following an Event of Default, Collateral Trustee shall have given notice to Borrower Representative suspending such rights, provided that: no such notice shall be required if a Loan Party has commenced an Insolvency Proceeding and,
in any event, no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such terms. All such rights
to vote and give consents, waivers and ratifications shall terminate upon the occurrence and during the continuation of an Event of Default and the notification by Collateral Trustee to Borrower Representative of the exercise of remedies in
accordance with the terms hereof. Notwithstanding anything to the contrary contained herein or in any other Loan Document, no actions under applicable foreign law to perfect or create any security interest over the Shares or any property or other
assets of any Foreign Subsidiary shall be required with respect to any Foreign Subsidiary not required to become a Borrower or Guarantor hereunder in accordance with Section 6.11(b). 

5.    REPRESENTATIONS AND WARRANTIES 

Each Loan Party represents and warrants as follows: 

5.1    Due Organization, Authorization; Power and Authority. 

(a)    Each Loan Party and each of its Subsidiaries are duly existing and in good standing as a Registered Organization in
their respective jurisdictions of formation and are qualified and licensed to do business and are in good standing in any other jurisdiction in which the conduct of their respective business or ownership of property require that they be qualified
except where the failure to do so could not reasonably be expected to have a Material Adverse Effect. In connection with this Agreement, Borrower Representative has delivered to Administrative Agent a completed certificate signed by Borrower
Representative entitled “Perfection Certificate”. Except to the extent Borrower Representative has provided notice of a legal name change in accordance with Section 7.2, (i) each Loan Party’s
exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (ii) each Loan Party is an organization of the type and is organized in the jurisdiction set forth in the Perfection Certificate; (iii) the
Perfection Certificate accurately sets forth each Loan Party’s organizational identification number or accurately states that such Loan Party has none; (iv) the Perfection Certificate accurately sets forth each Loan Party’s place of
business, or, if more than one, its chief executive office as well as such Loan Party’s mailing address (if different than its chief executive office); (v) except as set forth in the Perfection Certificate, each Loan Party (and each of its
predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its jurisdiction; and (vi) all other information set forth on the
Perfection Certificate pertaining to each Loan Party and each of its Subsidiaries is accurate and complete in all material respects (it being understood and agreed that each Loan Party may from time to time update certain information in the
Perfection Certificate after the Closing Date to the extent the change does not arise from an action, event or circumstance restricted by one or more specific provisions in this Agreement. 

(b)    The execution, delivery and performance by each Loan Party of the Loan Documents to which it is a party have been
duly authorized, and do not (i) conflict with such Loan Party’s Operating Documents or other organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law,
(iii) contravene, conflict or violate any applicable material order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which such Loan Party or any of its Subsidiaries or any of their property or assets
may be bound or affected, (iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full
force and effect), or (v) conflict with, contravene, constitute a default or breach under, or result in or permit the termination or acceleration of, any material agreement by which such Loan Party is bound. No Loan Party is in default under
any agreement to which it is a party or by which it is bound in which the default could reasonably be expected to have a Material Adverse Effect. 

  
 6 













 5.2    Collateral. 

(a)    Each Loan Party has good title to, rights in, and the power to transfer each item of the Collateral upon which it
purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. 
 (b)    Except for the
Collateral Accounts described in the Perfection Certificate or in a notice timely delivered pursuant to Section 6.6, no Loan Party has any Collateral Accounts at or with any bank, broker or other financial institution, and
each Loan Party has taken such actions as are necessary to give Collateral Trustee a perfected security interest therein as required pursuant to the terms of Section 6.6(b). The Accounts (if any) are bona fide, existing
obligations of the Account Debtors. 
 (c)    The Collateral is located only at the locations identified in the
Perfection Certificate and other Permitted Locations. The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate or as disclosed in writing pursuant to
Section 6.12. 
 (d)    Each Loan Party is the sole owner of the Intellectual Property which
it owns or purports to own except for (i) licenses constituting “Permitted Transfers”, (ii) open-source software, (iii) over-the-counter software
that is commercially available to the public, (iv) material Intellectual Property licensed to such Loan Party and noted on the Perfection Certificate or as disclosed pursuant to Section 6.7(b), and (v) immaterial
Intellectual Property licensed to such Loan Party. Each Patent (other than patent applications) which it owns or purports to own and which is material to such Loan Party’s business is valid and enforceable, and no part of the Intellectual
Property which a Loan Party owns or purports to own and which is material to the Loan Parties’ business has been judged invalid or unenforceable, in whole or in part. To the best of each Loan Party’s knowledge, no claim has been made that
any part of the Intellectual Property violates the rights of any third party except to the extent such claim could not reasonably be expected to have a Material Adverse Effect. Except as noted on the Perfection Certificate or as disclosed pursuant
to Section 6.7(b), no Loan Party is a party to, nor is it bound by, any Restricted License. No Subsidiary which is not a Loan Party owns any Intellectual Property, which, if not owned by Loan Parties and their Subsidiaries
would reasonably be expected to have a Material Adverse Effect. 
 5.3    Accounts; Material Agreements.
The Accounts (if any) of the Loan Parties are bona fide existing obligations. The property or services giving rise to such Accounts have been delivered or rendered.    The licenses and agreements to which any Loan Party or any of
its Subsidiaries is a party is in good standing and in full force and effect and no Loan Party is in material breach with respect thereto, except to the extent of any such licenses and agreements, the failure of which to maintain, could reasonably
be expected to have a Material Adverse Effect. 
 5.4    Litigation and Proceedings. Except as set forth
in the Perfection Certificate or as disclosed in writing pursuant to Section 6.2, there are no actions, suits, litigations or proceedings, at law or in equity, pending, or, to the knowledge of any Responsible Officer,
threatened in writing, by or against any Loan Party or any of its Subsidiaries, officers or directors involving more than, individually or in the aggregate for all related proceedings, $500,000 or in which any adverse decision has had or could
reasonably be expected to have any Material Adverse Effect. 
 5.5    Financial Statements; Financial
Condition. All consolidated and consolidating (if applicable) financial statements for the Loan Parties and each of their Subsidiaries delivered to Administrative Agent fairly present in all material respects the consolidated and consolidating
financial condition and results of operations of the Loan Parties and each of their Subsidiaries as of the respective dates and for the respective periods then ended, and there are no material liabilities (including any contingent liabilities) which
are not reflected in such financial statements. There has not been any material deterioration in (i) the consolidated financial condition of the Loan Parties and their Subsidiaries taken as a whole, or (ii) the Collateral, in each case,
since the date of the most recent financial statements submitted to Administrative Agent, as determined by Administrative Agent acting in its reasonable discretion. 

5.6    Solvency. The fair salable value of the assets (including goodwill minus disposition costs) of the
Loan Parties and their Subsidiaries, on a consolidated basis, exceeds the fair value of liabilities of the Loan Parties’ and their Subsidiaries, on a consolidated basis; no Loan Party is left with unreasonably small capital after the
transactions in this Agreement; and the Loan Parties and their Subsidiaries, on a consolidated basis, are able to pay their debts (including trade debts) as they mature. 

  
 7 













 5.7    Consents; Approvals. Each Loan Party and each of
its Subsidiaries have obtained all third party consents, approvals, waivers, made all declarations or filings with, given all notices to, and obtained all consents, licenses, permits or other approvals from all Governmental Authorities that are
necessary (i) to enter into the Loan Documents and consummate the transactions contemplated thereby, and (ii) to continue their respective businesses as currently conducted, except (with respect to this clause (ii)) where failure to
do so could not reasonably be expected to result in a Material Adverse Effect. 
 5.8    Subsidiaries;
Investments. No Loan Party has any Subsidiaries, except as noted on the Perfection Certificate or as disclosed to Administrative Agent pursuant to Section 6.11 below. No Loan Party owns any stock, partnership, or other
ownership interest or other Equity Interests except for Permitted Investments. 
 5.9    Tax Returns and
Payments. Each Loan Party and each of its Subsidiaries have timely filed all required tax returns and reports (or appropriate extensions therefor), and such Loan Party and each of its Subsidiaries has timely paid all foreign, federal, state and
local taxes, assessments, deposits and contributions owed by such Loan Party or such Subsidiary, as applicable, except (a) to the extent such taxes are being contested in good faith by appropriate proceedings promptly instituted and diligently
conducted, so long as such reserve or other appropriate provision, if any, as shall be required in conformity with GAAP shall have been made therefor, or (b) if such taxes, assessments, deposits and contributions do not, individually or in the
aggregate, exceed Twenty-Five Thousand Dollars ($25,000). No Loan Party is aware of any claims or adjustments proposed for any prior tax years of such Loan Party or any of its Subsidiaries which could result in a material amount of additional taxes
becoming due and payable by such Loan Party or Subsidiary. 
 5.10    Shares. Such Loan Party has full
power and authority to create a first lien on the Shares and no disability or contractual obligation exists that would prohibit such Loan Party from pledging the Shares pursuant to this Agreement. There are no subscriptions, warrants, rights of
first refusal or other restrictions on transfer relative to, or options exercisable with respect to the Shares of Borrower Representative or any other wholly-owned Subsidiary. The Shares have been and will be duly authorized and validly issued, and
are fully paid and non-assessable.    As of the date hereof, the Shares are not the subject of any present or threatened suit, action, arbitration, administrative or other proceeding, and
such Loan Party knows of no reasonable grounds for the institution of any such proceedings. 

5.11    Compliance with Laws. 

(a)    No Loan Party or Subsidiary of a Loan Party is an “investment company” or an “affiliated person”
of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the Investment Company Act of 1940 as amended. 

(b)    No Loan Party or Subsidiary of a Loan Party is engaged, nor will it engage, principally or as one of its important
activities, in the business of extending credit for the purpose of “purchasing” or “carrying” any “margin security” as such terms are defined in Regulation U of the Federal Reserve Board as now and from time to time
hereafter in effect (such securities being referred to herein as “Margin Stock”). None of the proceeds of the Loans or other extensions of credit under this Agreement have been (or will be) used, directly or indirectly, for the

payment if such Borrower maintained a balance sufficient to satisfy the required payment in the Collateral Account designated for payment in the ACH Authorization and Borrowers make the required payment within three (3) Business Days following

(b)    A Loan Party fails or neglects to perform, keep, or observe any other term, provision, condition, covenant or

hereof are not, within twenty (20) days after the occurrence thereof, discharged or stayed (whether through the posting of a bond or otherwise); provided, however, no Loans shall be made during any twenty (20) day cure period; or 

(b)    (i) Any material portion of the assets of a Loan Party or any of its Subsidiaries is attached, seized, levied on,
or comes into possession of a trustee or receiver, or (ii) any court order enjoins, restrains, or prevents a Loan Party or any of its Subsidiaries from conducting all or any material part of its business, and, in case such court

or modified to avoid such restriction on the operation of the business within twenty (20) days following the entry thereof. 

8.5    Insolvency. (a) A Loan Party or any of its Subsidiaries, as a whole, is unable to pay its debts

8.6    Other Agreements. There is, under any agreement to which a Loan Party or any of its Subsidiaries is a
party with a third party or parties, (a) any default (after giving effect to any applicable cure or grace periods) resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in
an amount individually or in the aggregate in excess of $500,000 (except if such third party is restricted from accelerating the maturity of such Indebtedness, including pursuant to the terms of a subordination or similar agreement entered into with

8.10    Governmental Approval. Any Governmental Approval shall have been revoked, rescinded, suspended,
modified in an adverse manner or not renewed for a full term, and such revocation, rescission, suspension, modification or non-renewal has, or could reasonably be expected to have, a Material Adverse Effect.

 9.    COLLATERAL
TRUSTEE’S RIGHTS AND REMEDIES 
 9.1    Acceleration. Upon the occurrence and during the
continuation of an Event of Default, Administrative Agent, is entitled, without notice or demand, to declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all
Obligations are immediately due and payable without any action by Administrative Agent), and to stop advancing money or extending credit for any Borrower’s benefit under this Agreement (and each Lender’s Commitment shall be deemed
terminated as long as an Event of Default has occurred and is continuing). 

  
 17 













 9.2    Remedies. Upon the occurrence and during the
continuation of an Event of Default, Collateral Trustee is entitled, solely at the direction of Administrative Agent, subject to the terms of the Collateral Trust Agreement, without notice or demand, to do any or all of the following, to the extent
not prohibited by applicable law: 
 (a)    verify the amount of, demand payment of and performance under, and collect
any Accounts and General Intangibles, settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Administrative Agent may determine is advisable, and notify any Person owing a Loan Party money of
Collateral Trustee’s security interest in such funds; 
 (b)    make any payments and do any acts it considers
necessary or reasonable to protect the Collateral and/or its security interest in the Collateral; 
 (c)    ratably
apply to the Obligations any amount held by Collateral Trustee owing to or for the credit or the account of a Loan Party; 

(d)    ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the
Collateral; 
 (e)    deliver a notice of exclusive control, any entitlement order, or other directions or instructions
pursuant to any Account Control Agreement or similar agreements providing control of any Collateral; 
 (f)    demand
and receive possession of any Loan Party’s Books; and 
 (g)    exercise all rights and remedies available to
Collateral Trustee under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof). 

Loan Parties shall assemble the Collateral if Collateral Trustee requests and make it available as Collateral Trustee designates. Collateral
Trustee may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all
expenses incurred. Each Loan Party grants Collateral Trustee a license to enter and occupy any of its premises, without charge, to exercise any of Collateral Trustee’s rights or remedies. Collateral Trustee is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, a Loan Party’s labels, Patents, Copyrights, mask works, rights of use of any name, trade secrets, trade names, Trademarks, and
advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Collateral Trustee’s exercise of its rights under this Section,
a Loan Party’s rights under all licenses and all franchise agreements inure to Collateral Trustee’s benefit. If, after the acceleration of the Obligations, a Loan Party receives proceeds of Collateral, such Loan Party shall to deliver such
proceeds to Collateral Trustee, for the ratable benefit of Lenders, to be applied to the Obligations. 

9.3    Power of Attorney. Each Loan Party hereby irrevocably appoints Collateral Trustee (and any of
Collateral Trustee’s partners, managers, officers, agents or employees) as its lawful attorney-in-fact, with full power of substitution, exercisable upon the
occurrence and during the continuation of an Event of Default, to: (a) send requests for verification of Accounts or notify Account Debtors of Collateral Trustee’s security interest and Liens in the Collateral; (b) endorse such Loan
Party’s name on any checks or other forms of payment or security; (c) sign such Loan Party’s name on any invoice or bill of lading for any Account or drafts against Account Debtors schedules and assignments of Accounts, verifications
of Accounts, and notices to Account Debtors; (d) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Administrative Agent or Collateral Trustee determine reasonable; (e) make,
settle, and adjust all claims under such Loan Party’s insurance policies; (f) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise
take any action to terminate or discharge the same; (g) transfer the Collateral into the name of Collateral Trustee or a third party as the Code permits; and (h) dispose of the Collateral. Each Loan Party further hereby appoints Collateral
Trustee (and any of Collateral Trustee’s partners, managers, officers, agents or employees) as its lawful attorney-in-fact, with full power of substitution,
regardless of whether or 

  
 18 













 
not an Event of Default has occurred or is continuing to: (i) sign such Loan Party’s name on any documents and other Security Instruments necessary to perfect or continue the perfection
of, or maintain the priority of, Collateral Trustee’s security interest in the Collateral, (ii) take all such actions which such Loan Party is required, but fails to do under the covenants and provisions of the Loan Documents;
(iii) take any and all such actions as Collateral Trustee may reasonably determine to be necessary or advisable for the purpose of maintaining, preserving or protecting the Collateral or any of the rights, remedies, powers or privileges of
Collateral Trustee under this Agreement or the other Loan Documents. Collateral Trustee’s foregoing appointment as each Loan Party’s attorney in fact, and all of Collateral Trustee’s rights and powers, coupled with an interest, are
irrevocable until all Obligations (other than contingent indemnification obligations as to which no claim has been asserted or is known to exist) have been fully repaid, in cash, and otherwise fully performed and all commitments to make Loans
hereunder have been terminated. 
 9.4    Protective Payments. If a Loan Party fails to obtain the
insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which may be required to preserve the Collateral, Collateral Trustee may obtain such insurance or make such payment,
and all amounts so paid by Collateral Trustee are Lender Expenses and immediately due and payable, bearing interest at the then highest rate applicable to the Obligations, and secured by the Collateral. Collateral Trustee will make reasonable
efforts to provide Borrower Representative with notice of Collateral Trustee obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Collateral Trustee are deemed an agreement to make similar
payments in the future or Collateral Trustee’s waiver of any Event of Default. 
 9.5    Application of
Payments and Proceeds Upon Default. If an Event of Default has occurred and is continuing, Collateral Trustee shall have the right to apply in any order any funds in its possession, whether payments, proceeds realized as the result of any
collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations, for the ratable benefit of Lenders. Collateral Trustee shall pay any surplus to Borrowers by credit to the Deposit Account designated by Borrowers or as
directed by a court of competent jurisdiction. Borrowers shall remain liable to Collateral Trustee and Lenders for any deficiency. If Collateral Trustee, as directed by Administrative Agent in Administrative Agent’s good faith business
judgment, directly or indirectly, enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Collateral Trustee may, at the direction of Administrative Agent, either reduce the Obligations by the
principal amount of the purchase price or defer the reduction of the Obligations until the actual receipt by Collateral Trustee of cash or immediately available funds therefor. 

9.6    Collateral Trustee’s Liability for Collateral. So long as Collateral Trustee complies with
reasonable secured lender practices regarding the safekeeping of the Collateral in the possession or under the control of Collateral Trustee, Collateral Trustee shall not be liable or responsible for: (a) the safekeeping of the Collateral;
(b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Loan Parties bear all risk of loss, damage or destruction of
the Collateral. 
 9.7    No Waiver; Remedies Cumulative. Any failure by Administrative Agent, Collateral
Trustee or any Lender, at any time or times, to require strict performance by each Loan Party of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Administrative Agent, Collateral Trustee or
any Lender thereafter to demand strict performance and compliance herewith or therewith. Collateral Trustee’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Collateral Trustee has all rights and remedies
provided under the Code, by law, or in equity. Collateral Trustee or any Lender’s exercise of one right or remedy is not an election and shall not preclude Collateral Trustee or any Lender from exercising any other remedy under this Agreement
or other remedy available at law or in equity, and any waiver of any Event of Default is not a continuing waiver. Any delay in exercising any remedy is not a waiver, election, or acquiescence. 

9.8    Demand Waiver. Each Loan Party waives presentment, demand, notice of default or dishonor, notice of
payment and nonpayment, release, compromise, settlement, extension, or renewal of accounts, documents, instruments or chattel paper. 

9.9    Shares. Each Loan Party recognizes that Collateral Trustee may be unable to effect a public sale of
any or all the Shares, by reason of certain prohibitions contained in federal securities laws and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers
which will be obliged to agree, among other things, to acquire such securities for their own account for 

  
 19 













 
investment and not with a view to the distribution or resale thereof. Each Loan Party acknowledges and agrees that any such private sale may result in prices and other terms less favorable than
if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. Collateral Trustee shall be under no obligation to delay a sale of any
of the Shares for the period of time necessary to permit the issuer thereof to register such securities for public sale under federal securities laws or under applicable state securities laws, even if such issuer would agree to do so. 

10.    NOTICES

 11.    CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER 

Except as otherwise expressly provided in any of the Loan Documents, this Agreement and the other Loan Documents shall be governed by, and
construed in accordance with, the laws of the State of New York without regard to principles of conflicts of law. Each party hereto hereby submits to the exclusive jurisdiction of the State and Federal courts in New York County, City of New York,
New York; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Collateral Trustee from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other
security for the Obligations, or to enforce a judgment or other court order in favor of Administrative Agent, Collateral Trustee or any Lender. Each party hereto expressly submits and consents in advance to such jurisdiction in any action or suit
commenced in any such court, and each party hereto waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is
deemed appropriate by such court. Each party hereto waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered
or certified mail addressed to such party at the address set forth in, or subsequently provided by such party in accordance with, Section 10 and that service so made shall be deemed completed upon the earlier to occur of
such party’s actual receipt thereof or three (3) Business Days after deposit in the U.S. mails, proper postage prepaid. Each party hereto hereby expressly waives any claim to assert that the laws of any other jurisdiction govern this
Agreement. 
 TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES HERETO EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR THE PARTIES TO ENTER
INTO THIS AGREEMENT. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT OR ANYWHERE ELSE, EACH PARTY HERETO AGREES THAT IT SHALL NOT SEEK FROM ANY OTHER PARTY UNDER ANY THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS), ANY
SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES. EACH PARTY HERETO HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 

  
 21 













 This Section 11 shall survive the termination of this Agreement.

 12.    GENERAL PROVISIONS 

12.1    Termination Prior to Term Loan Maturity Date; Survival; Release of Collateral. All covenants,
representations and warranties and grants of security interests made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than contingent indemnification obligations as to
which no claim has been asserted or is known to exist and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied in full, in cash and all commitments to extend credit pursuant to this
Agreement have terminated (such date, the “Discharge Date”). So long as Borrowers have satisfied the Obligations (other than contingent indemnification obligations as to which no claim has been asserted or is known to exist
and any other obligations which, by their terms, are to survive the termination of this Agreement), this Agreement and any remaining commitments to extend credit may be terminated prior to the Term Loan Maturity Date by Borrowers, by written notice
of termination to Lenders. Those obligations that are expressly specified in this Agreement as surviving this Agreement’s termination shall continue to survive notwithstanding this Agreement’s termination. Promptly after the Discharge
Date, Lenders shall direct Collateral Trustee to deliver evidence of the release of Collateral. 

12.2    Successors and Assigns. 

(a)    Successors and Assigns Generally. This Agreement binds and is for the benefit of the successors and
permitted assigns of each party. No Loan Party may assign this Agreement or any rights or obligations under it without Lenders’ prior written consent (which may be granted or withheld in each Lender’s discretion). 

(b)    Assignment by Lenders. Each Lender has the right, without the consent of the Loan Parties, to sell,
transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, such Lender’s obligations, rights, and benefits under this Agreement and the other Loan Documents, provided that without prior written consent of
Borrower Representative, as long as no Event of Default has occurred and is continuing, no Lender shall assign or grant voting participation to a direct competitor of Borrowers or to a vulture fund or to the extent otherwise restricted in any other
Loan Document. Each such Lender shall notify the Administrative Agent of such assignment and deliver to the Administrative Agent a copy of any assignment and assumption agreement entered into in connection thereto. 

(c)    Register; Participant Register. Administrative Agent, acting solely for this purpose as an agent of the Loan
Parties, shall maintain at one of its offices in the United States a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Term Loans owing to each Lender
pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Loan Parties, Administrative Agent and the Lenders shall treat each Person whose name is
recorded in the Register pursuant to the terms hereof as Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Loan Parties, any Lender and the Collateral Trustee at any reasonable time and from
time to time upon reasonable prior notice. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Loan Parties, maintain a register on which it enters the name and address of each participant and
the principal amounts (and stated interest) of each participant’s interest in the Term Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to
disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant’s interest in any commitments, loans 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. For the avoidance of doubt, Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. 

  
 22 













 12.3    Indemnification. Each Loan Party agrees to
indemnify, defend and hold Administrative Agent, Collateral Trustee and each Lender and their respective directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Lender (each, an “Indemnified
Person”) harmless against: (i) all obligations, demands, claims, and liabilities (including such claims, costs, expenses, damages and liabilities based on liability in tort, including strict liability in tort) (collectively,
“Claims”) claimed or asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (ii) all losses or expenses (including Lender Expenses) in any way suffered, incurred, or paid by such
Indemnified Person as a result of, following from, consequential to, or arising from transactions among Administrative Agent, Collateral Trustee, Lenders and Loan Parties (including reasonable and documented attorneys’ fees and expenses) except
for Claims and/or losses to the extent directly caused by such Indemnified Person’s gross negligence or willful misconduct or any Claims and/or losses with respect to any actions among Indemnified Persons in each case, for the avoidance of
doubt. This Section 12.3 shall survive until all statutes of limitation with respect to the Claims, losses, and expenses for which indemnity is given shall have run. This Section 12.3 shall not apply with respect to Taxes
other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim. 

12.4    Borrower Liability. If any Person is joined to this Agreement as a Borrower, the following
provisions shall apply: Each Borrower hereunder shall be jointly and severally obligated to repay all Loans made hereunder, regardless of which Borrower actually receives said Loan, as if each Borrower hereunder directly received all Loans. Each
Borrower waives (a) any suretyship defenses available to it under the Code or any other applicable law, and (b) any right to require Collateral Trustee to: (i) proceed against any Borrower or any other person; (ii) proceed
against or exhaust any security; or (iii) pursue any other remedy. Collateral Trustee may exercise or not exercise any right or remedy it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting any Borrower’s liability. Notwithstanding any other provision of this Agreement or other related document, each Borrower irrevocably waives all rights that it may have at
law or in equity (including, without limitation, any law subrogating Borrower to the rights of Collateral Trustee under this Agreement) to seek contribution, indemnification or any other form of reimbursement from any other Borrower, or any other
Person now or hereafter primarily or secondarily liable for any of the Obligations, for any payment made by such Borrower with respect to the Obligations in connection with this Agreement or otherwise and all rights that it might have to benefit
from, or to participate in, any security for the Obligations as a result of any payment made by a Borrower with respect to the Obligations in connection with this Agreement or otherwise. Any agreement providing for indemnification, reimbursement or
any other arrangement prohibited under this Section shall be null and void. If any payment is made to a Borrower in contravention of this Section, such Borrower shall hold such payment in trust for Lenders and such payment shall be promptly
delivered to Collateral Trustee, for the ratable benefit of Lenders, for application to the Obligations, whether matured or unmatured. 

12.5    Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement.

 12.6    Severability of Provisions. Each provision of this Agreement is severable from every other
provision in determining the enforceability of any provision. 
 12.7    Correction of Loan Documents.
Administrative Agent may correct patent errors and fill in any blanks in the Loan Documents consistent with the agreement of the parties. 

12.8    Amendments in Writing; Waiver; Integration. No purported amendment or modification of any Loan
Document, or waiver, discharge or termination of any obligation under any Loan Document, shall be effective except, pursuant to an agreement in writing by the parties thereto, and in case of this Agreement, pursuant to an agreement in writing
entered into by Borrowers, Administrative Agent, the Required Lenders and Collateral Trustee, provided that Collateral Trustee’s approval shall not be required for any amendment or supplement that has the effect solely of (i) adding or
maintaining Collateral, securing additional Obligations that are otherwise permitted by the terms of this Agreement to be secured by the Collateral or preserving, perfecting or establishing the priority of the Liens thereon or the rights of
Collateral Trustee therein; (ii) curing any ambiguity, defect or inconsistency; (iii) providing for the assumption of a Borrower’s or Guarantor’s Obligations under any Loan Document in the case of a merger or consolidation or
sale of all or substantially all of the assets of a Borrower or Guarantor, as applicable; (iv) making any change that would provide any additional rights or benefits to the Administrative Agent, any Lender or Collateral Trustee or that does not
adversely affect the legal rights under this Agreement or any other Loan Document of Collateral Trustee; or (v) to the extent the Collateral Trust Agreement does not require Collateral Trustee’s approval to such amendment or modification.
It is agreed that any change to the definition of “Designated Holder” or the rights 

  
 23 













 
of a Designated Holder in Section 6.14 (and any change to this Agreement that would modify the consent required pursuant to this sentence) shall require the consent of
the Collateral Trustee. Without limiting the generality of the foregoing, no oral promise or statement, nor any action, inaction, delay, failure to require performance or course of conduct shall operate as, or evidence, an amendment, supplement or
waiver or have any other effect on any Loan Document. Any waiver granted shall be limited to the specific circumstance expressly described in it, and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give
rise to, or evidence, any obligation or commitment to grant any further waiver. The Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings,
representations, warranties, and negotiations among the parties about the subject matter of the Loan Documents merge into the Loan Documents. 

12.9    Counterparts; Electronic Execution of Documents. This Agreement and any other Loan Documents, except
to the extent otherwise required pursuant to the terms thereof, may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together,
constitute one Agreement. The words “execution,” “signed,” “signature” and words of like import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of
which shall be of the same legal effect, validity and enforceability as a manually executed signature or the use of a paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any applicable law, including, without
limitation, any state law based on the Uniform Electronic Transactions Act. Delivery of an executed counterpart of a signature page of any Loan Document by electronic means including by email delivery of a “.pdf” format data file shall be
effective as delivery of an original executed counterpart of such Loan Document. 
 12.10    Confidentiality;
Publicity. 
 (a)    In handling any confidential information, Administrative Agent, Collateral Trustee and each
Lender agree to exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to its Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of any
interest in the Loans so long as such parties are bound by confidentiality terms consistent in all material respects with the terms hereof; (c) as required by law, regulation, subpoena, or other order and in connection with reporting
obligations applicable to Administrative Agent, Collateral Trustee or such Lender, including pursuant to the Exchange Act, (d) to Administrative Agent, Collateral Trustee or such Lender’s regulators or as otherwise required in connection
with any examination or audit; (e) as Administrative Agent, Collateral Trustee or such Lender considers reasonably appropriate in connection with the exercise of remedies with respect to the Obligations; and (f) to third-party service
providers of Administrative Agent, Collateral Trustee or such Lender so long as such service providers are bound by confidentiality terms not more permissive than the terms hereof. Confidential information does not include information that is
either: (i) in the public domain or in Administrative Agent, Collateral Trustee or any Lender’s possession when disclosed to Administrative Agent, Collateral Trustee or such Lender, as applicable, or becomes part of the public domain
(other than as a result of its disclosure by Administrative Agent, Collateral Trustee or such Lender in violation of this Agreement) after disclosure to Administrative Agent, Collateral Trustee or such Lender, as applicable; or (ii) disclosed
to Administrative Agent, Collateral Trustee or such Lender by a third party, if Administrative Agent, Collateral Trustee or such Lender, as applicable, does not know that the third party is prohibited from disclosing the information. The provisions
of this paragraph shall survive the termination of this Agreement. 
 (b)    Neither party hereto shall publicize or use
the other party’s name or logo, or hyperlink to such other parties’ website, describe the relationship of the parties or the transaction contemplated by this Agreement, in written and oral presentations, advertising, promotional and
marketing materials, client lists, public relations materials or on its web site (together, the “Publicity Materials”) without prior written notice to the party that is the subject of the proposed Publicity Materials, together with
a draft (or, if Publicity Materials are not proposed to be delivered in written form, an outline of the content to be included) so as to provide such subject party a reasonable opportunity to review prior to publication, and each party agrees, in
connection with any Publicity Materials proposed by such party to reasonably consider requested changes or corrections requested by the party that is the subject of such Publicity Materials in good faith, and upon request, to provide the final form
prior to publication or other dissemination. 
 12.11    Borrower Representative. Each of the Borrowers
hereby appoints Borrower Representative to act as its exclusive agent for all purposes under the Loan Documents (including, without limitation, with respect to all 

  
 24 













 
matters related to the borrowing and repayment of any Loan). Each of the Borrowers acknowledges and agrees that (a) Borrower Representative may execute such documents on behalf of any
Borrower as Borrower Representative deems appropriate in its sole discretion and each Borrower shall be bound by and obligated by all of the terms of any such document executed by Borrower Representative on its behalf, (b) any notice or other
communication delivered hereunder to Borrower Representative shall be deemed to have been delivered to each Borrower and (c) Administrative Agent, Collateral Trustee and any Lender shall accept (and shall be permitted to rely on) any document
or agreement executed by Borrower Representative on behalf of Borrowers (or any of them). Each Borrower must act through the Borrower Representative for all purposes under this Agreement and the other Loan Documents. Notwithstanding anything
contained herein to the contrary, to the extent any provision in this Agreement requires any Borrower to interact in any manner with Administrative Agent, Collateral Trustee or any Lender, such Borrower shall do so through Borrower Representative.

 12.12    Captions. The headings used in this Agreement are for convenience only and shall not affect
the interpretation of this Agreement. 
 12.13    Construction of Agreement. The parties mutually
acknowledge that they and their attorneys have participated in the preparation and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties caused the uncertainty to exist. 

12.14    Relationship. The relationship of the parties to this Agreement is determined solely by the
provisions of this Agreement. Except to the extent set forth herein, the parties do not intend to create any agency, partnership, joint venture, trust, fiduciary or other relationship with duties or incidents different from those of parties to an arm’s-length contract. 
 12.15    Third Parties. Nothing in this
Agreement, whether express or implied, is intended to: (a) confer any benefits, rights or remedies under or by reason of this Agreement on any persons other than the express parties to it and their respective permitted successors and assigns;
(b) relieve or discharge the obligation or liability of any person not an express party to this Agreement; or (c) give any person not an express party to this Agreement any right of subrogation or action against any party to this
Agreement. 
 12.16    Appointment of Collateral Trustee. Each Lender hereby appoints Collateral Trustee
to act on behalf of Lenders as collateral agent under this Agreement and the other Loan Documents, and to hold and enforce any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations, all in accordance with
the terms of the Collateral Trust Agreement. The provisions of this Section 12.16 are solely for the benefit of Collateral Trustee and Lenders and no Loan Party nor any other Person shall have any rights as a third party beneficiary of
any of the provisions hereof. The Collateral Trustee may resign or be removed or replaced, and a successor Collateral Trustee may be appointed in accordance with the terms and subject to the conditions of the Collateral Trust Agreement. 

12.17    Appointment of Administrative Agent. 

(a)    Each Lender hereby appoints Administrative Agent to act on behalf of Lenders as administrative agent under this
Agreement and the other Loan Documents. The provisions of this Section 12.17 are solely for the benefit of Administrative Agent and Lenders and no Loan Party nor any other Person shall have any rights as a third party
beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement, Administrative Agent does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or
for any Loan Party or any other Person. Administrative Agent shall not have any duties or responsibilities except for those expressly set forth in this Agreement and the other Loan Documents, together with such powers as are reasonably related
thereto. The duties of Administrative Agent shall be mechanical and administrative in nature and Administrative Agent shall not have, or be deemed to have, by reason of this Agreement, any other Loan Document or otherwise a fiduciary relationship in
respect of any Lender. 
 (b)    If Administrative Agent shall request instructions from Lenders with respect to any act
or action (including failure to act) in connection with this Agreement or any other Loan Document, then Administrative Agent shall be entitled to refrain from such act or taking such action unless and until it shall have received instructions from
the Required Lenders, and Administrative Agent shall incur no liability to any Person by reason of so refraining. Administrative Agent shall be fully justified in failing or refusing to take any action hereunder or under any other


  
 25 













 
Loan Document for any reason. Without limiting the foregoing, no Lender shall have any right of action whatsoever against Administrative Agent as a result of Administrative Agent’s acting or
refraining from acting hereunder or under any other Loan Document in accordance with the instructions of Lenders. 

(c)    Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder by or
through any one or more sub-agent s appointed by Administrative Agent. Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its
rights and powers by or through their respective and their respective related parties. The exculpatory provisions of this Section 12.17 shall apply to any such sub-agent and to the
related parties of such Administrative Agent and any such sub-agent. No Administrative Agent shall be responsible for the negligence or misconduct of any sub-agent
except to the extent that a court of competent jurisdiction determines in a final and non-appealable judgment that such Administrative Agent acted with gross negligence or willful misconduct in the selection
of such sub-agents. 
 (d)    Neither Administrative Agent nor any of its
Affiliates nor any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the other Loan Documents, except for damages
solely caused by its or their own gross negligence or willful misconduct as finally determined by a court of competent jurisdiction. Without limitation of the generality of the foregoing, Administrative Agent: (i) may consult with legal
counsel, independent chartered accountants and other experts and consultants selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants, experts
or consultants; (ii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement or the other Loan Documents;
(iii) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of any Loan Party or to inspect the Collateral
(including the books and records) of any Loan Party; (iv) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or the other Loan Documents or any
other instrument or document furnished pursuant hereto or thereto; and (v) shall incur no liability under or in respect of this Agreement or the other Loan Documents by acting upon any notice, consent, certificate or other instrument or writing
(which may be by email, telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties. 

(e)    With respect to its Commitments and Loans hereunder, Administrative Agent shall have the same rights and powers
under this Agreement and the other Loan Documents as any other Lender and may exercise the same as though it were not Administrative Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include
Administrative Agent in its individual capacity (to the extent it holds any Obligations owing to Lenders or Commitments hereunder). Administrative Agent and each of its Affiliates may lend money to, invest in, and generally engage in any kind of
business with, any Loan Party, any of their Affiliates and any Person who may do business with or own securities of any Loan Party or any such Affiliate, all as if Administrative Agent was not Administrative Agent and without any duty to account
therefor to Lenders. Administrative Agent and its Affiliates may accept fees and other consideration from any Loan Party for services in connection with this Agreement or otherwise without having to account for the same to Lenders. 

(f)    Each Lender acknowledges that it has, independently and without reliance upon Administrative Agent or any other
Lender, made its own credit and financial analysis of the Loan Parties and its own decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon Administrative Agent or any other Lender
and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. Each Lender acknowledges the potential conflict of interest of each
other Lender as a result of Lenders holding disproportionate interests in the Loans, and expressly consents to, and waives any claim based upon, such conflict of interest. 

(g)    Each Lender agrees to indemnify Administrative Agent (to the extent not reimbursed by Loan Parties and without
limiting the obligations of Loan Parties hereunder), ratably according to its respective Pro Rata Share, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against Administrative Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by Administrative Agent
in connection therewith; provided, however, that no Lender shall 

  
 26 













 
be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from Administrative
Agent’s gross negligence or willful misconduct as finally determined by a court of competent jurisdiction. Without limiting the foregoing, each Lender agrees to reimburse Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable and documented counsel fees) incurred by Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and each other Loan Document, to the extent that
Administrative Agent is not reimbursed for such expenses by the Loan Parties. 
 (h)    Administrative Agent may resign
at any time by giving not less than thirty (30) days’ prior written notice thereof to Lenders, Collateral Trustee and Borrower Representative. Upon any such resignation, Lenders shall have the right to appoint a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by Lenders and shall have accepted such appointment within thirty (30) days after Administrative Agent’s giving notice of resignation, then Administrative Agent may,
on behalf of Lenders, appoint a successor Administrative Agent, which shall be a Lender, if a Lender is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary of a commercial bank or
financial institution if such commercial bank or financial institution has combined capital of at least $300,000,000. If no successor Administrative Agent has been appointed pursuant to the foregoing, by the 30th day after the date such notice of
resignation was given by the resigning Administrative Agent, such resignation shall become effective and Lenders shall thereafter perform all the duties of Administrative Agent hereunder until such time, if any, as Lenders appoint a successor
Administrative Agent as provided above. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall succeed to and become vested with all the rights, powers,
privileges and duties of the resigning Administrative Agent. Upon the earlier of the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent or the effective date of the resigning Administrative
Agent’s resignation, the resigning Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that any indemnity, expense reimbursement or other rights in favor of such
resigning Administrative Agent shall continue. After any resigning Administrative Agent’s resignation hereunder, the provisions of this Section 12.17 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement and the other Loan Documents. Notwithstanding the foregoing, as long as K2 HealthVentures LLC is a Lender pursuant to this Agreement, K2 HealthVentures LLC shall not resign as
Administrative Agent unless a successor Administrative Agent is appointed concurrently with such resignation, which successor Administrative Agent shall have the wherewithal to perform, and shall succeed to and become vested with all the rights,
powers, privileges and duties of the resigning Administrative Agent under this Agreement and the other Loan Documents. 

(i)    In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such
rights, upon the occurrence and during the continuation of any Event of Default, with the prior written consent of Administrative Agent, each Lender and each holder of any Obligation is hereby authorized at any time or from time to time, without
notice to any Loan Party or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all balances held by it at any of its offices for the account of any Loan Party or any Subsidiary of a
Loan Party (regardless of whether such balances are then due to such Loan Party or such Subsidiary) and any other properties or assets any time held or owing by that Lender or that holder to or for the credit or for the account of any Loan Party or
any Subsidiary of a Loan Party against and on account of any of the Obligations which are not paid when due. Any Lender or holder of any Obligation exercising a right to set off or otherwise receiving any payment on account of the Obligations in
excess of its Pro Rata Share thereof in accordance with the terms of this Agreement relating to the priority of the repayment of the Obligations shall purchase for cash (and the other Lenders or holders shall sell) such participations in each such
other Lender’s or holder’s Pro Rata Share of the Obligations as would be necessary to cause such Lender to share the amount so set off or otherwise received with each other Lender or holder in accordance with their respective Pro Rata
Shares and in accordance with the terms of this Agreement relating to the priority of the repayment of the Obligations. Each Loan Party agrees, to the fullest extent permitted by law, that (i) any Lender or holder may exercise its right to set
off with respect to amounts in excess of its Pro Rata Share of the Obligations and may sell participations in such amount so set off to other Lenders and holders and (ii) any Lender or holders so purchasing a participation in the Loans made or
other Obligations held by other Lenders or holders may exercise all rights of set-off, bankers’ Lien, counterclaim or similar rights with respect to such participation as fully as if such Lender or holder
were a direct holder of the Loans and the other Obligations in the amount of such participation. Notwithstanding the foregoing, if all or any portion of the set-off amount or payment otherwise received is
thereafter recovered from Lender that has exercised the right of set-off, the purchase of participations by that Lender shall be rescinded and the purchase price restored without interest. 

  
 27 













 (j)    Nothing in this Agreement or the other Loan Documents shall be
deemed to require Administrative Agent to advance funds on behalf of any Lender or to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Borrowers may have against any Lender as a result of
any default by such Lender hereunder. To the extent that Administrative Agent advances funds to Borrowers on behalf of any Lender and is not reimbursed therefor on the same Business Day as such advance is made, Administrative Agent shall be entitled
to retain for its account all interest accrued on such advance until reimbursed by the applicable Lender. 
 (k)    If
Administrative Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or will be received by Administrative Agent from Borrowers and such related payment is not received thereby, then
Administrative Agent will be entitled to recover such amount from such Lender on demand without set-off, counterclaim or deduction of any kind. 

(l)    If Administrative Agent determines at any time that any amount received thereby under this Agreement shall be
returned to Borrowers or paid to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement or any other Loan Document, Administrative Agent will not be required to distribute
any portion thereof to any Lender. In addition, each Lender will repay to Administrative Agent on demand any portion of such amount that Administrative Agent has distributed to such Lender, together with interest at such rate, if any, as
Administrative Agent is required to pay to Borrowers or such other Person, without set-off, counterclaim or deduction of any kind. 

(m)    Administrative Agent will use reasonable efforts to provide Lenders with any written notice of Event of Default
received by Administrative Agent from, or delivered by Administrative Agent to, any Loan Party; provided, however, that Administrative Agent shall not be liable to any Lender for any failure to do so, except to the extent that such
failure is attributable solely to Administrative Agent’s gross negligence or willful misconduct as finally determined by a court of competent jurisdiction. 

(n)    Anything in this Agreement or any other Loan Document to the contrary notwithstanding, each Lender hereby agrees
with each other Lender and with Administrative Agent that no Lender shall take any action to protect or enforce its rights arising out of this Agreement or any other Loan Document (including exercising any rights of
set-off) without first obtaining the prior written consent of the Required Lenders, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the other Loan
Documents shall be taken in concert and at the direction or with the consent of Administrative Agent at the request of Required Lenders. 

13.    GUARANTY 

13.1    Guaranty. Each Guarantor, including Parent, who has executed this Agreement as of the date hereof,
together with each Loan Party who accedes to this Agreement as a Guarantor after the date hereof pursuant to Section 6.11 hereby, jointly and severally, unconditionally and irrevocably, guarantees the prompt and complete
payment and performance by Borrowers and the other Loan Parties when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations. In furtherance of the foregoing, and without limiting the generality thereof, each Guarantor
agrees as follows: 
 (a)    each Guarantor’s liability hereunder shall be the immediate, direct, and primary
obligation of such Guarantor and shall not be contingent upon any exercise or enforcement of any remedy of Collateral Trustee, Administrative Agent or Lender or that any of them may have against a Borrower, or any other Guarantor or other Person
liable in respect of the Obligations, or all or any portion of the Collateral; and 
 (b)    Administrative Agent, on
behalf of Lenders, may enforce this guaranty notwithstanding the existence of any dispute between any Secured Party and any Loan Party with respect to the existence of any Event of Default. 

13.2    Maximum Liability. Anything herein or in any other Loan Document to the contrary notwithstanding,
the maximum liability of each Guarantor shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal, state provincial or territorial laws relating to the insolvency of debtors (after giving effect to the
right of contribution established in Section 13.5). 

  
 28 













 13.3    Termination. The guaranty pursuant to this
Section 13 shall remain in full force and effect until the date the Obligations have been paid in full in cash, and all commitments to extend credit have been terminated. 

13.4    Unconditional Nature of Guaranty. No payment made by a Borrower, Guarantor, any other guarantor or
any other Person or received or collected by any Secured Party from a Borrower, Guarantor, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or
application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment
(other than any payment made by such Guarantor in respect of the Obligations or any payment received or collected from such Guarantor in respect of the Obligations), remain liable for the Obligations up to the maximum liability of such Guarantor
hereunder until the date the Obligations are paid in full in cash. 
 13.5    Right of Contribution 

(a)    If in connection with any payment made by any Guarantor hereunder any rights of contribution arise in favor of such
Guarantor against one or more other Guarantors, such rights of contribution shall be subject to the terms and conditions of Section 13.6. The provisions of this Section 13.5 shall in no respect
limit the obligations and liabilities of any Guarantor pursuant to the Loan Documents, and each Guarantor shall remain liable for the full amount guaranteed by such Guarantor hereunder. 

(b)    Notwithstanding any payment made by any Guarantor hereunder or any set-off
or application of funds of any Guarantor by any Secured Party, no Guarantor shall be entitled to be subrogated to any of the rights of any Secured Party against any Loan Party or any collateral security or guarantee or right of offset held by any
Secured Party for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from any Loan Party in respect of payments made by such Guarantor hereunder, in each case, until the Termination
Date. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time prior to the Termination Date, such amount shall be held by such Guarantor in trust for the ratable benefit of the Secured Parties, shall be
segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to Administrative Agent, if
required), to be applied to the Obligations, irrespective of the occurrence or the continuance of any Event of Default. 

13.6    Amendments, etc. with respect to the Obligations. Each Guarantor shall remain obligated hereunder
notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Obligations made by any Secured Party may be rescinded and any of the
Obligations continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Secured Party, and this Agreement, the other Loan Documents and any other documents executed and delivered in connection therewith may be amended,
modified, supplemented or terminated, in whole or in part, in accordance with their respective terms, and any collateral security, guarantee or right of offset at any time held by any Secured Party for the payment of the Obligations may be sold,
exchanged, waived, surrendered or released. No Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for the guarantee pursuant to this
Section 13 or any property subject thereto. 
 13.7    Guarantee Absolute and
Unconditional; Guarantor Waivers; Guarantor Consent. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by any Secured Party upon the guaranty
contained in this Section 13 or acceptance of this guaranty. The Obligations shall conclusively be deemed to have been created, contracted or incurred, or renewed, 

  
 29 













 
extended, amended or waived, in reliance upon this guaranty. All dealings between Borrowers, Guarantors and any Secured Party shall be conclusively presumed to have been had or consummated in
reliance upon this guaranty. Each Guarantor further waives: 
 (a)    diligence, presentment, protest, demand for payment
and notice of default or nonpayment to or upon any Borrower or any of the other Guarantors with respect to the Obligations; 

(b)    the defense of the statute of limitations in any action hereunder or for the collection or performance of the
Obligations; 
 (c)    any defense arising by reason of any lack of corporate or other authority or any other defense of
any Borrower, such Guarantor or any other Person; 
 (d)    any defense based upon errors or omissions by any Secured
Party in the administration of the Obligations; 
 (e)    any rights to set-offs
and counterclaims; 
 (f)    any defense based upon an election of remedies (including, if available, an election to
proceed by nonjudicial foreclosure) which destroys or impairs the subrogation rights of such Guarantor or the right of such Guarantor to proceed against any Borrower or any other obligor of the Obligations for reimbursement; and 

(g)    without limiting the generality of the foregoing, to the fullest extent permitted by law, any defenses or benefits
that may be derived from or afforded by applicable law that limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of this Agreement. 

Each Guarantor understands and agrees that the guarantee contained in this Section 13 shall be construed as a continuing, absolute
and unconditional guarantee of payment without regard to (i) the validity or enforceability of this Agreement or any other Loan Document, any of the Obligations or any other collateral security therefor or guaranty or right of offset with
respect thereto at any time or from time to time held by any Secured Party, (ii) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to
or be asserted by any Borrower or any other Person against any Secured Party, or (iii) any other circumstance whatsoever (with or without notice to or knowledge of any Loan Party) which constitutes, or might be construed to constitute, an
equitable or legal discharge of any Borrower for the Obligations, or of such Guarantor under this guaranty, in bankruptcy or in any other instance, (iv) any Insolvency Proceeding with respect to any Loan Party or any other Person, (v) any
amalgamation, merger, acquisition, consolidation or change in structure of any Loan Party or any other Person, or any sale, lease, transfer or other disposition of any or all of the assets or Equity Interests of any Loan Party or any other Person,
(vi) any assignment or other transfer, in whole or in part, of Secured Parties’ interests in and rights under this Agreement or the other Loan Documents, including the right to receive payment of the Obligations, or any assignment or other
transfer, in whole or in part, of any Secured Party’s interests in and to any of the Collateral, (vii) any Secured Party’s vote, claim, distribution, election, acceptance, action or inaction in any Insolvency Proceeding related to any
of the Obligations, and (viii) any other guaranty, whether by such Guarantor or any other Person, of all or any part of the Obligations or any other indebtedness, obligations or liabilities of any Guarantor to Secured Parties. When making any
demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, Secured Parties may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against
any Loan Party or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto. Any failure by any Secured Party to make any such demand, to pursue such other rights or remedies or
to collect any payments from any Loan Party or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of any Loan Party or any other Person or any such collateral
security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any Secured Party
against any Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings. 

13.8    Modifications of Obligations. Each Guarantor further unconditionally consents and agrees that,
without notice to or further assent from any Guarantor: (a) the principal amount of the Obligations may be increased or decreased and additional indebtedness or obligations of a Borrower or any other Persons under the Loan Documents may be
incurred, by one or more amendments, modifications, renewals or extensions of any Loan Document or otherwise; (b) the time, manner, place or terms of any payment under any Loan Document may be extended or changed, including by an increase or
decrease in the interest rate on any Obligation or any fee or other amount payable under such Loan Document, by an amendment, modification or renewal of any Loan Document or otherwise; (c) the 

  
 30 













 
time for a Borrower’s (or any other Loan Party’s) performance of or compliance with any term, covenant or agreement on its part to be performed or observed under any Loan Document may
be extended, or such performance or compliance waived, or failure in or departure from such performance or compliance consented to, all in such manner and upon such terms as the applicable Secured Party may deem proper; (d) in addition to the
Collateral, Secured Parties may take and hold other security (legal or equitable) of any kind, at any time, as collateral for the Obligations, and may, from time to time, in whole or in part, exchange, sell, surrender, release, subordinate, modify,
waive, rescind, compromise or extend such security and may permit or consent to any such action or the result of any such action, and may apply such security and direct the order or manner of sale thereof; (e) Secured Parties may discharge or
release, in whole or in part, any other Guarantor or any other Loan Party or other Person liable for the payment and performance of all or any part of the Obligations, and may permit or consent to any such action or any result of such action, and
shall not be obligated to demand or enforce payment upon any of the Collateral, nor shall any Secured Party be liable to any Guarantor for any failure to collect or enforce payment or performance of the Obligations from any Person or to realize upon
the Collateral, and (f) Secured Parties may request and accept other guaranties of the Obligations and any other indebtedness, obligations or liabilities of a Borrower or any other Loan Party to any Secured Party and may, from time to time, in
whole or in part, surrender, release, subordinate, modify, waive, rescind, compromise or extend any such guaranty and may permit or consent to any such action or the result of any such action; in each case (a) through (f), as the applicable
Secured Parties may deem advisable, and without impairing, abridging, releasing or affecting this Agreement. 

13.9    Reinstatement. The guaranty shall continue to be effective, or be reinstated, as the case may
be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by any Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of a Loan Party, or
upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, a Loan Party or any substantial part of its property, or otherwise, all as though such payments had not been made. 

13.10    No Waiver by Course of Conduct; Cumulative Remedies. No Secured Party shall by any act (except in
writing in accordance with Section 12.9), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default, as applicable. No failure
to exercise, nor any delay in exercising, on the part of any Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other
or further exercise thereof or the exercise of any other right, power or privilege. A waiver by any Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which any Secured Party
would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law. 

13.11    Enforcement Expenses; Indemnification. Each Guarantor agrees to pay or reimburse Secured Parties
for all its costs and expenses incurred in collecting against such Guarantor under this guaranty or otherwise enforcing or preserving any rights under this Agreement and the other Loan Documents to which such Guarantor is a party, including, without
limitation, the reasonable and documented fees and disbursements of counsel.
