 (b)
No Default or Event of Default (other than the Existing Event of Default) has occurred and is continuing;

unsuspected, both at law and in equity, which Borrower or any of its respective successors, assigns, or other legal representatives may now or hereafter own, hold, have or claim to have against the Releasees or any of them for, upon, or by reason of
any circumstance, action, cause or thing whatsoever which arises at any time on or prior to the day and date of this Amendment, including, without limitation, for or on account of, or in relation to, or in any way in connection with any of the
Credit Agreement, or any of the other Loan Documents or transactions thereunder or related thereto, other than to the extent of those Claims which arise from the gross negligence or willful misconduct of the applicable Releasee as determined in a

negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP; provided that, until so amended, such ratio or requirement shall continue to be computed in accordance with GAAP
prior to such change therein. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by
the Code to the extent such terms are defined therein. 
 2 LOAN AND TERMS OF PAYMENT 

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

2.1.1 Term Loans. 
 (a)
Availability. Subject to the terms and conditions of this Agreement, the Lenders agree, severally and not jointly to make term loans to Borrower on the Closing Date in an aggregate amount of Thirty Two Million Dollars ($32,000,000.00)
according to each Lender’s Term Loan Commitment as set forth on Schedule 1.1 hereto (such term loans are hereafter referred to singly as a “Term Loan”, and collectively, as the “Term Loans”. After
repayment, no Term Loan may be re-borrowed. 
 (b) Repayment. Borrower shall make monthly payments of interest only on account of the
Term Loans commencing on the first (1st) Payment Date following the Funding Date of the Term Loan, and continuing on the Payment Date of each successive month thereafter through and including the Payment Date immediately preceding the
Amortization Date. Commencing on the Amortization Date, and continuing on the Payment Date of each month thereafter, Borrower shall make consecutive equal monthly payments of principal and interest, in arrears, to each Lender, as calculated by
Collateral Agent (which calculations shall be deemed correct absent manifest error) based upon: (1) the amount of such Lender’s Term Loan, (2) the effective rate of interest, as determined in Section 2.2(a), and (3) a
repayment schedule equal to thirty six (36) months. All unpaid principal and accrued and unpaid interest with respect to each Term Loan is due and payable in full on the Maturity Date. Each Term Loan may only be prepaid in accordance with
Sections 2.1.1(d) and/or 2.1.1(e). 
 (c) Final Payment. On the Maturity Date or such earlier date in accordance with Sections
2.1.1(d) and/or 2.1.1(e) hereof, Borrower shall pay, in addition to the unpaid principal and accrued interest and all other amounts due on such date with respect to the Term Loans (or, in the case of partial prepayments, the Term Loan being
prepaid), an amount equal to the Final Payment with respect to the Term Loans (or, in the case of partial prepayments, the Term Loan being prepaid). 

 (d) Permitted Prepayment. Borrower shall have the option to prepay all or any portion of
the Term Loans advanced by the Lenders under this Agreement, provided (i) Borrower provides written notice to Collateral Agent of its election to prepay the Term Loans at least five (5) Business Days prior to such prepayment, and
(ii) Borrower pays to the Lenders on the date of such prepayment, in accordance with each Lender’s respective Pro Rata Share, an amount equal to the sum of (A) all outstanding principal of the Term Loans prepaid plus accrued and
unpaid interest thereon through the prepayment date, (B) the Final Payment applicable to the prepaid Term Loans, (C) the Prepayment Fee applicable to the prepaid Term Loans, plus (D) all other Obligations that are due and payable,
including Lenders’ Expenses and interest at the Default Rate with respect to any past due amounts. Notwithstanding anything in this Agreement to the contrary, if Borrower refinances the Obligations under this Agreement with another credit
facility provided by Lenders to Borrower primarily for such purpose, then the Prepayment Fee otherwise due hereunder shall not be due and payable. 

(e) Mandatory Prepayment Upon an Acceleration. If the Term Loans are accelerated, upon the occurrence of an Event of Default, Borrower
shall immediately pay to the Lenders, on the date of such prepayment, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of: (i) all outstanding principal plus accrued and unpaid interest on the
Term Loans, (ii) the Final Payment, (iii) the Prepayment Fee, plus (iv) 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.

interest shall be payable monthly, in arrears, in accordance with Section 2.2(e) below, at a fixed per annum rate equal to nine and one quarter of one percent (9.25%). Interest shall accrue on the principal amount outstanding under each Term
Loan through and including the day on which such Term Loan is paid in full. 
 (b) Default Rate. Immediately upon the occurrence and
during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum which is five percentage points (5.00%) above the rate that is otherwise applicable thereto (the “Default Rate”). Payment or
acceptance of the increased interest rate provided in this Section 2.2(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 of
Collateral Agent or any Lender. 
 (c) 360-Day Year. Interest shall be computed on the basis of a 360-day year consisting of twelve
(12) months of thirty (30) days. 
 (d) Debit of Accounts. Collateral Agent and each Lender may debit any of
Borrower’s deposit accounts, including the Designated Deposit Account, through automatic debit of such accounts, Automated Clearinghouse (“ACH”) or other transfers, for principal and interest payments when due and, following
notice thereof to Borrower and Borrower’s failure to remit payment thereof within fifteen (15) calendar days of such notice, any other amounts Borrower owes the Lenders. These debits shall not constitute a set-off.

indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such time as the Lenders’ obligation to make Credit Extensions has terminated, all pursuant to

Lenders hereby authorize the Collateral Agent to 

  
 - 4 - 

 
release the Collateral in accordance with the immediately preceding sentence and further authorize Collateral Agent to release any Collateral to which legal title of such Collateral has
transferred to another Person pursuant to a transaction permitted pursuant to and in accordance with Section 7.1 at the time of such legal transfer of title. 

4.2 Authorization to File Financing Statements. Borrower hereby authorizes Collateral Agent to file financing statements, without
notice to Borrower, with all appropriate jurisdictions to perfect or protect Collateral Agent’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either Borrower or any other Person, shall be deemed to
violate the rights of Collateral Agent under the Code. Such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in
Collateral Agent’s discretion. 
 5 REPRESENTATIONS AND WARRANTIES 

Borrower represents and warrants as follows: 

5.1 Due Organization, Authorization; Power and Authority. Borrower is duly organized and validly existing in its jurisdiction of
formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the failure to do so could not reasonably
be expected to have a Material Adverse Change. In connection with this Agreement, Borrower has delivered to Collateral Agent a completed certificate signed by Borrower, entitled “Perfection Certificate”. Borrower represents and
warrants to Collateral Agent that (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) Borrower is an organization of the type and is organized in the jurisdiction set
forth in the Perfection Certificate; (c) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower has none; (d) the Perfection Certificate accurately sets
forth Borrower’s place of business, or, if more than one, Borrower’s chief executive office as well as Borrower’s mailing address (if different than its chief executive office); (e) Borrower (and none 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 (f) all other information set forth on the Perfection Certificate
pertaining to Borrower and its Subsidiaries is accurate and complete (it being understood and agreed that Borrower may from time to time update certain information in the Perfection Certificate after the Closing Date to the extent permitted by one
or more specific provisions in this Agreement). If Borrower is not now a Registered Organization but later becomes one, Borrower shall promptly notify Collateral Agent of such occurrence and provide Collateral Agent with Borrower’s
organizational identification number. 
 The execution, delivery and performance by Borrower of the Loan Documents to which it is a party
have been duly authorized, and do not (i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict
or violate any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any 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 (a) such Governmental Approvals which have already been obtained and are in full force and effect and (b) any filings
required by the Loan Documents in connection with the security interests granted herein) or (v) constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it
is a party or by which it is bound in which the default could have a Material Adverse Change. 
 5.2 Collateral. Borrower has good
title to, has rights in, and the power to transfer each item of the Collateral upon which it purports to grant a Lien under the Loan Documents to which it is a party, free and clear of any and all Liens except Permitted Liens. Borrower does not have
any deposit accounts other than the deposit accounts described in the Perfection Certificate delivered to Collateral Agent in connection herewith, or of which Borrower has given Collateral Agent notice and taken such actions as are necessary to give
Collateral Agent a perfected security interest therein.  
 Except for Clinical Testing Assets, the Collateral is not in the
possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate. None of the components of the Collateral 

  
 - 5 - 

 
shall be maintained at locations other than as provided in the Perfection Certificate or as permitted pursuant to Section 7.2. In the event that Borrower, after the date hereof, intends to
store or otherwise deliver any portion of the Collateral (excluding Clinical Testing Assets) to a bailee, then Borrower will first receive the written consent of Collateral Agent and the Lenders and Borrower shall use its commercially reasonable
efforts to cause such bailee to execute and deliver a bailee agreement in form and substance reasonably satisfactory to Collateral Agent and the Lenders in its reasonable discretion. The term “Clinical Testing Assets” shall include all
clinical trial supplies or equipment maintained at pre-clinical and/or clinical testing sites or located with a manufacturer or a distributor. Notwithstanding the foregoing, Collateral Agent and the Lenders reserve the right to require Borrower, in
the future, to use commercially reasonable efforts to cause each such manufacturer and/or distributor where Borrower maintains Clinical Testing Assets with a cost in excess of One Hundred Thousand Dollars ($100,000.00) to execute and deliver to
Collateral Agent and the Lenders a bailee agreement in form and substance reasonably satisfactory to Collateral Agent and the Lenders. 

Borrower is the sole owner of the Intellectual Property that it owns or purports to own except for (a) non-exclusive licenses granted to
its customers in the ordinary course of business, (b) Permitted Intellectual Property Licenses, (c) over-the-counter software that is commercially available to the public, and (d) material Intellectual Property licensed to Borrower
and noted on the Perfection Certificate. To the best of Borrower’s knowledge, each Patent which it owns or purports to own and that is material to Borrower’s business is valid and enforceable, with respect to issued patents, or includes
patentable claims(s), with respect to pending patent applications, and no part of the Intellectual Property that Borrower owns or purports to own and which is material to Borrower’s business has been judged invalid or unenforceable, in whole or
in part. To the best of Borrower’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 would not reasonably be expected to have a Material Adverse
Change. Except as noted on the Perfection Certificate, Borrower is not a party to, nor is it bound by, any Restricted License. 
 5.3
Litigation. Except as set forth in the Perfection Certificate or as otherwise disclosed to Collateral Agent and each Lender pursuant to Section 6.2(g), there are no actions or proceedings pending or, to the knowledge of the Responsible
Officers, threatened in writing by or against Borrower or any of its Subsidiaries involving more than Two Hundred Fifty Thousand Dollars ($250,000.00). 

5.4 No Material Deviation in Financial Statements. All consolidated financial statements for Borrower and its Subsidiaries delivered to
Collateral Agent and each Lender fairly present in all material respects Borrower’s and each Subsidiaries’ consolidated financial condition and consolidated results of operations as of the dates and for the periods stated therein. There
has not been any material deterioration in Borrower’s and its Subsidiaries’ consolidated financial condition since the date of the most recent financial statements submitted to any Lender. 

5.5 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of
its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature. 

5.6 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled” by an “investment
company” under the Investment Company Act of 1940, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). Borrower
has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary
company” of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to have a
Material Adverse Change. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing,
treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all
Governmental Authorities that are necessary to continue their respective businesses as currently conducted. 

  
 - 6 - 

 None of Borrower, any of its Subsidiaries, or any of Borrower’s or its Subsidiaries’
Affiliates or any of their respective agents acting or benefiting in any capacity in connection with the transactions contemplated by this Agreement is (i) in violation of any Anti-Terrorism Law,
(ii) engaging in or conspiring to engage in any transaction that evades or avoids, or has the purpose of evading or avoiding or attempts to violate, any of the prohibitions set forth in any Anti-Terrorism
Law, or (iii) is a Blocked Person. None of Borrower, any of its Subsidiaries, or to the knowledge of Borrower and any of their Affiliates or agents, acting or benefiting in any capacity in connection with the transactions contemplated by this
Agreement, (x) conducts any business or engages in making or receiving any contribution of funds, goods or services to or for the benefit of any Blocked Person, or (y) deals in, or otherwise engages in any transaction relating to, any
property or interest in property blocked pursuant to Executive Order No. 13224, any similar executive order or other Anti-Terrorism Law. 

5.7 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for Permitted
Investments. 
 5.8 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required tax returns and
reports, and has timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower, except for the failure to timely pay state and local taxes that could not reasonably be expected to cause a Material
Adverse Change and that could not reasonably be expected to create a Lien on any Collateral other than a “Permitted Lien.” Borrower may defer payment of any contested taxes, provided that Borrower (a) in good faith contests its
obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Collateral Agent and each Lender in writing of the commencement of, and any material development in, any proceedings in which
the amount of contested taxes exceeds or reasonably would be expected to exceed Fifty Thousand Dollars ($50,000.00), (c) posts bonds or takes any other steps required to prevent the governmental authority levying such contested taxes from
obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”. Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and
payable by Borrower. Borrower has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, as applicable, and Borrower has not withdrawn from participation in, and has not
permitted partial or complete termination of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency, as applicable. 
 5.9 Use of Proceeds. Borrower shall
use the proceeds of the Credit Extensions solely as working capital and to fund its general business requirements, and to refinance existing Indebtedness, and not for personal, family, household or agricultural purposes. A portion of the proceeds of
the Term Loans shall be used by Borrower to repay the Oxford Existing Indebtedness in full on the Closing Date. 
 5.10 Full
Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Collateral Agent or any Lender, as of the date such representation, warranty, or other statement was made, taken
together with all such written certificates and written statements given to Collateral Agent or any Lender, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the
certificates or statements not misleading (it being recognized by Collateral Agent and the Lenders that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual
results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results).

Lien.” 
 6.5 Insurance. Keep its, and cause each Subsidiary to keep its respective business and the Collateral insured

(a) Borrower acknowledges that any Lender with the word “SBIC” in its name, is a Federal licensee under the Small Business

(b) As a condition to any Credit Extension, Borrower shall, upon request of Collateral Agent or any Lender, complete and deliver to Collateral
Agent and such Lender SBA Forms 480, 652 and 1031, the SBA Economic Impact Assessment. Any information provided by Borrower to Collateral Agent or any Lender on each such form is and will be true, accurate and complete in all material respects.

financing pursuant to 13 C.F.R. Section 107.720. So long as any Obligations are owing to Collateral Agent or any Lender under the Loan Documents, Borrower will at all times comply with all non-discrimination requirements applicable to Borrower
under federal law.

(b) pay any other Obligations within three (3) Business Days after such Obligations are due and payable (which three (3) day grace period shall not apply to payments due on the Maturity Date). During the cure period, the failure to

such ten (10) day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional period (which shall not in any case exceed thirty (30) days) to attempt to cure such default, and within such
reasonable time period the failure to cure the default shall not

 9 LENDERS’ RIGHTS AND REMEDIES 

9.1 Rights and Remedies. While an Event of Default occurs and continues Collateral Agent may, and at the written direction of Required
Lenders shall, without notice or demand, do any or all of the following: 
 (a) 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 Collateral Agent or the Lenders); 

(b) stop advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower
and Collateral Agent and/or the Lenders; 
 (c) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and
in any order that Collateral Agent and the Required Lenders considers advisable, notify any Person owing Borrower money of Collateral Agent’s security interest in such funds, and verify the amount of such account; 

(d) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the
Collateral. Borrower shall assemble the Collateral if Collateral Agent requests and make it available as Collateral Agent designates. Collateral Agent 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. Borrower grants Collateral Agent a license to enter and occupy any of its premises,
without charge, to exercise any of Collateral Agent’s rights or remedies; 
 (e) apply to the Obligations any (i) balances and
deposits of Borrower it holds, or (ii) any amount held by Collateral Agent and/or the Lenders owing to or for the credit or the account of Borrower; 

(f) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Collateral Agent
is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, Patents, Copyrights, mask works, rights of use of any name, trade secrets, trade names, Trademarks, service marks, 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 Agent’s exercise of its rights under this Section,
Borrower’s rights under all licenses and all franchise agreements inure to Collateral Agent, for the benefit of the Lenders; 
 (g)
place a “hold” on any account maintained with Collateral Agent or the Lenders and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any Control Agreement or similar agreements
providing control of any Collateral; 
 (h) demand and receive possession of Borrower’s Books; and 

(i) exercise all rights and remedies available to Collateral Agent and each Lender 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). 
 9.2 Power of Attorney.
Borrower hereby irrevocably appoints Collateral Agent as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of
payment or security; (b) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts
and on terms Collateral Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to
the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Collateral Agent or a third party as the Code permits. Borrower hereby appoints
Collateral Agent as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of  

  
 - 15 - 

 
Collateral Agent’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than inchoate indemnity obligations) have been
satisfied in full and Collateral Agent and the Lenders are under no further obligation to make Credit Extensions hereunder. Collateral Agent’s foregoing appointment as Borrower’s attorney in fact, and all of Collateral Agent’s rights
and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed and Collateral Agent’s and the Lenders’ obligation to provide Credit Extensions
terminates. 
 9.3 Protective Payments. If Borrower 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 Borrower is obligated to pay under this Agreement or any other Loan Document, Collateral Agent may obtain such insurance or make such payment, and all amounts so paid by Collateral Agent are
Lenders’ Expenses and immediately due and payable, bearing interest at the then highest applicable rate, and secured by the Collateral. Collateral Agent will make reasonable efforts to provide Borrower with notice of Collateral Agent obtaining
such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Collateral Agent are deemed an agreement to make similar payments in the future or Collateral Agent’s waiver of any Event of Default. 

9.4 Application of Payments and Proceeds. Borrower shall not have any right to specify the order or the accounts to which Collateral
Agent and/or the Lenders shall allocate or apply any payments required to be made by Borrower to Collateral Agent and/or the Lenders or otherwise received by Collateral Agent and/or the Lenders under this Agreement when any such allocation or
application is not specified elsewhere in this Agreement. If an Event of Default has occurred and is continuing, Collateral Agent and/or the Lenders may apply any funds in its possession, whether from Borrower account balances, payments, proceeds
realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Collateral Agent and/or the Lenders shall determine in its sole discretion. Any surplus shall be paid to
Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Collateral Agent and/or the Lenders for any deficiency. If Collateral Agent and/or any Lender, in its good faith business judgment, directly or indirectly enters
into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Collateral Agent and/or such Lender shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the
purchase price or deferring the reduction of the Obligations until the actual receipt by Collateral Agent and/or such Lender of cash therefor. 

9.5 Lenders’ Liability for Collateral. So long as Collateral Agent and the Lenders comply with their obligations under the Code
and with reasonable practices regarding the safekeeping of the Collateral in the possession or under the control of Collateral Agent and the Lenders, Collateral Agent and the Lenders 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. Subject to Collateral Agent’s and
the Lender’s obligations under the Code, Borrower bears all risk of loss, damage or destruction of the Collateral. 
 9.6 No
Waiver; Remedies Cumulative. Failure by Collateral Agent or any Lender, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right
of Collateral Agent or any Lender thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by Collateral Agent and the Required Lenders and then is only effective for the
specific instance and purpose for which it is given. The rights and remedies of Collateral Agent and the Lenders under this Agreement and the other Loan Documents are cumulative. Collateral Agent and the Lenders have all rights and remedies provided
under the Code, by law, or in equity. The exercise by Collateral Agent or any Lender of one right or remedy is not an election, and shall not preclude Collateral Agent or any Lender from exercising any other remedy under this Agreement or other
remedy available at law or in equity, and Collateral Agent’s or any Lender’s waiver of any Event of Default is not a continuing waiver. Collateral Agent’s or any Lender’s delay in exercising any remedy is not a waiver, election,
or acquiescence.  
 9.7 Demand Waiver. Borrower, for itself an on behalf of each Subsidiary, waives demand, notice of default
or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Collateral Agent or any
Lender on which Borrower is liable.

 11 CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE 

California law governs the Loan Documents without regard to principles of conflicts of law. Borrower, Collateral Agent and each Lender each
submit to the exclusive jurisdiction of the State and Federal courts in San Diego County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Collateral Agent or any Lender 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 

  
 - 17 - 

 
Collateral Agent or any Lender. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection
that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service
of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in
Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid. 

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER, COLLATERAL AGENT AND EACH LENDER 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 EACH PARTY TO ENTER
INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’
AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time
shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the San Diego County, California Superior Court) appointed in accordance with California Code of Civil
Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in San Diego County, California; and the parties hereby submit to
the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power,
among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and
confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference
procedures, then such party may apply to the San Diego County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence
applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee
discovery and may enforce all discovery rules and order applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the
action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise
self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph. 

12 GENERAL PROVISIONS 

12.1 Successors and Assigns. (a) This Agreement binds and is for the benefit of the successors and permitted assigns of each
party. Borrower may not assign this Agreement or any rights or obligations under it without Collateral Agent’s and each Lender’s prior written consent (which may be granted or withheld in Collateral Agent’s and each Lender’s
discretion). Any Lender may at any time assign to one or more Eligible Assignees (a “Lender Transfer”) all or any portion of such Lender’s Term Loan Commitment and/or Credit Extensions, together with all related obligations of
such Lender hereunder. Notwithstanding anything to the contrary contained herein, so long as no Event of Default has occurred and is continuing, no Lender Transfer (other than a Lender Transfer (i) in respect of warrants or (ii) in
connection with (x) assignments by a Lender due to a forced divestiture at the request of any regulatory agency; or (y) upon the occurrence of a default, event of default or similar occurrence with respect to a Lender’s own financing
or securitization transactions) shall be permitted, without Borrower’s consent, to any Person which is an Affiliate or Subsidiary of Borrower or a direct competitor of Borrower, each as determined by Collateral Agent. Borrower and Collateral
Agent shall be entitled to continue to deal solely and directly with such  

  
 - 18 - 

 
Lender in connection with the interests so assigned until Collateral Agent shall have received and accepted an effective assignment agreement (each an “Assignment Agreement”)
in form and substance reasonably acceptable to Collateral Agent, executed, delivered and fully completed by the applicable parties thereto, and shall have received such other information regarding such Eligible Assignee as Collateral Agent
reasonably shall require. Notwithstanding anything set forth in this Agreement to the contrary, any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided, however, that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or
assignee for such Lender as a party hereto. 
 (b) Upon the request of the Eligible Assignee (and, as applicable, the assigning
Lender) pursuant to an effective Assignment Agreement, each Borrower shall execute and deliver to Collateral Agent for delivery to the Eligible Assignee (and, as applicable, the assigning Lender) secured promissory notes in the aggregate principal
amount of the Eligible Assignee’s Credit Extensions or Term Loan Commitment (and, as applicable, secured promissory notes to the assigning Lender in the principal amount of that portion of the principal amount of the Credit Extensions or Term
Loan Commitment retained by the assigning Lender). 
 (c) Collateral Agent, acting solely for this purpose as an agent of Borrower,
shall maintain at its offices located in Alexandria, Virginia a copy of each Assignment Agreement delivered to it and a register for the recordation of the names and addresses of each Lender, and the commitments of, and principal amounts (and stated
interest) of the Credit Extensions owing to, such Lender pursuant to the terms hereof (the “Register”). The entries in such Register shall be conclusive absent manifest error, and Borrower, Collateral Agent and Lenders may treat
each Person whose name is recorded therein pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. Such Register shall be available for inspection by Borrower and any Lender, at any reasonable time upon reasonable
prior notice to Collateral Agent.  
 (d) Notwithstanding anything to the contrary contained in this Agreement, Borrower, Collateral
Agent and each Lender agree to treat the Credit Extensions (including any secured promissory notes evidencing such Credit Extensions) as registered obligations and the right, title and interest of the Lenders and their assignees in and to such
Credit Extensions shall be assignable only upon notation of such assignment in the Register and no assignment thereof shall be effective until recorded therein. This Agreement shall be construed so that the Credit Extensions are at all times
maintained in “registered form” within the meaning of Section 5f.103-1(c) of the United States Treasury Regulations. 

12.2 Indemnification. Borrower agrees to indemnify, defend and hold Collateral Agent and the Lenders and their respective directors,
officers, employees, agents, attorneys, or any other Person affiliated with or representing Collateral Agent or the Lenders (each, an “Indemnified Person”) harmless against: (a) all obligations, demands, claims, and liabilities
(collectively, “Claims”) claimed or asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or expenses (including Lenders’ Expenses) in any way suffered,
incurred, or paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions between Collateral Agent, and/or the Lenders and Borrower (including reasonable attorneys’ fees and expenses), except
for Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct. 
 12.3 Time of
Essence. Time is of the essence for the performance of all Obligations in this Agreement. 
 12.4 Severability of
Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision. 

12.5 Correction of Loan Documents. Collateral Agent and the Lenders may correct patent errors and fill in any blanks in the Loan
Documents consistent with the agreement of the parties so long as Collateral Agent and the Lenders provide Borrower with written notice of such correction and allows Borrower at least ten (10) days to object to such correction. In the event of
such objection, such correction shall not be made except by an amendment signed by Collateral Agent, Lenders and Borrower.

 12.6 Amendments in Writing; Integration. (a) No amendment, modification, termination
or waiver of any provision of this Agreement or any other Loan Document, no approval or consent thereunder, or any consent to any departure by Borrower or any of its Subsidiaries therefrom, shall in any event be effective unless the same shall be in
writing and signed by Borrower, Collateral Agent and the Required Lenders provided that: 
 (i) no such amendment, waiver or other
modification that would have the effect of increasing or reducing a Lender’s Term Loan Commitment or Commitment Percentage shall be effective as to such Lender without such Lender’s written consent; 

(ii) no such amendment, waiver or modification that would affect the rights and duties of Collateral Agent shall be effective without
Collateral Agent’s written consent or signature; 
 (iii) no such amendment, waiver or other modification shall, unless signed by all
the Lenders directly affected thereby, (A) reduce the principal of, rate of interest on or any fees with respect to any Term Loan or forgive any principal, interest (other than default interest) or fees (other than late charges) with respect to
any Term Loan (B) postpone the date fixed for, or waive, any payment of principal of any Term Loan or of interest on any Term Loan (other than default interest) or any fees provided for hereunder (other than late charges or for any termination
of any commitment); (C) change the definition of the term “Required Lenders” or the percentage of Lenders which shall be required for the Lenders to take any action hereunder; (D) release all or substantially all of
any material portion of the Collateral, authorize Borrower to sell or otherwise dispose of all or substantially all or any material portion of the Collateral or release any Guarantor of all or any portion of the Obligations or its guaranty
obligations with respect thereto, except, in each case with respect to this clause (D), as otherwise may be expressly permitted under this Agreement or the other Loan Documents (including in connection with any disposition permitted hereunder);
(E) amend, waive or otherwise modify this Section 12.6 or the definitions of the terms used in this Section 12.6 insofar as the definitions affect the substance of this Section 12.6; (F) consent to the assignment, delegation

provisions of the foregoing clauses (i), (ii) and (iii) are subject to the provisions of any interlender or agency agreement among the Lenders and Collateral Agent pursuant to which any Lender may agree to give its consent in connection
with any amendment, waiver or modification of the Loan Documents only in the event of the unanimous agreement of all Lenders. 
 (b) Other
than as expressly provided for in Section 12.6(a)(i)-(iii), Collateral Agent may, if requested by the Required Lenders, from time to time designate covenants in this Agreement less restrictive
by notification to a representative of Borrower. 
 (c) This Agreement and the Loan Documents represent the entire agreement about this
subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement and the Loan Documents merge into this

parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Agreement.

Lenders shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of such confidential information may be made: (a) to the Lenders’ and Collateral Agent’s Subsidiaries or Affiliates

provision prior to such disclosure); (c) as required by law, regulation, subpoena, or other order; (d) to Lender’s or Collateral Agent’s regulators or as otherwise required in connection with a Lender’s or Collateral
