 1
ACCOUNTING AND OTHER TERMS 
 Accounting terms not defined in this Agreement shall be construed following GAAP.
Calculations and determinations must be made following GAAP. 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 Bank the outstanding principal
amount of all Credit Extensions and accrued and unpaid interest thereon as and when due in accordance with this Agreement. 

2.1.1 Term Loan. 
 (a) Availability. Subject to the terms and conditions of this Agreement, prior to the expiration of the Draw Period, Borrower may request, and Bank shall thereafter make term loan advances in an
aggregate amount of up to the Term Loan Amount (each, a “Term Advance” and, collectively, the “Term Advances”). Borrower may only request two (2) Term Advances hereunder and each Term Advance must be in an
amount equal to at least One Million Dollars ($1,000,000.00) provided that the final Term Advance may be in an amount less than One Million Dollars ($1,000,000.00) so long as it is in an amount equal to the remaining Term Loan Amount Borrower has
available to borrow under this Section 2.1.1. After repayment, no Term Advance (or any portion thereof) may be re-borrowed. 
 (b) Interest Period. Commencing on the first Payment Date following the Funding Date of the applicable Term Advance (or commencing on such Funding Date if such Funding Date is also a Payment Date),
and continuing on each Payment Date thereafter, Borrower shall make monthly payments of interest, in arrears, on the principal amount of each Term Advance at the rate set forth in Section 2.2(a). 

(c) Repayment. All outstanding principal and accrued and unpaid interest with respect to each Term Advance, and all other
outstanding Obligations with respect to such Term Advance, are due and payable in full on the Term Loan Maturity Date. The Term Loan may be prepaid at any time in full or in part without prepayment premium or penalty. 

2.2 Payment of Interest on the Credit Extensions. 
 (a) Interest Rate. Subject to Section 2.2(b), the principal amount outstanding under the Term Loan shall accrue interest at a fixed per annum rate equal to eleven percent (11.00%), which
interest shall be payable monthly on the Payment Date. 
 (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”) unless Bank otherwise
elects from time to time in its sole discretion to impose a smaller increase. Fees and expenses which are required to be paid by Borrower pursuant to the Loan Documents (including, without limitation, Bank Expenses) but are not paid when 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 2.2(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 Bank. 







 (c) Computation; 360-Day Year. In computing interest, the date of the making of any
Credit Extension shall be included and the date of payment shall be excluded; provided, however, that if any Credit Extension is repaid on the same day on which it is made, such day shall be included in computing interest on such
Credit Extension. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed. 
 (d)
Debit of Accounts. Bank may debit any of Borrower’s deposit accounts, including the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes Bank when due under the Loan Documents. These debits
shall not constitute a set-off. 
 2.3 Fees. Borrower shall pay to Bank: 

(a) Commitment Fee. A fully earned, non-refundable commitment fee of One Hundred Thousand Dollars ($100,000.00), payable on the
Effective Date (which, for the avoidance of doubt, shall be in addition to any fees payable under the Senior Loan Agreement); 

(b) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses for documentation and negotiation of
this Agreement, the Senior Loan Agreement and any other Loan Documents) incurred through and after the Effective Date, when due. 
 2.4 Payments. All payments (including prepayments) to be made by Borrower under any Loan Document shall be made in immediately available funds in Dollars, without setoff or counterclaim, before
12:00 noon Pacific time on the date when due. Payments of principal and/or interest received after 12:00 noon Pacific 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.

 3.4 Procedures for Borrowing. Subject to the prior satisfaction of all other
applicable conditions to the making of a Term Advance, each as set forth in this Agreement, to obtain a Term Advance, Borrower shall notify Bank (which notice shall be irrevocable) by electronic mail, facsimile, or telephone by 12:00 noon Pacific
time on the Funding Date of the Term Advance. Together with any such electronic or facsimile notification, Borrower shall deliver to Bank by electronic mail or facsimile a completed a Payment/Advance Form executed by a Responsible Officer or his or
her designee. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Bank shall credit such Term Advance to the Designated Deposit Account. Bank may make a Term Advance under this Agreement
based on instructions from a Responsible Officer or his or her designee or without instructions if a Term Advance is necessary to meet Obligations which have become due. 
 4 CREATION OF SECURITY INTEREST 
 4.1 Grant of Security
Interest. Borrower hereby grants Bank, to secure the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or
arising, and all proceeds and products thereof. 
 Borrower acknowledges that it previously has entered, and/or may in the
future enter, into Bank Services Agreements with Bank. Regardless of the terms of any Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder and that it is the intent of
Borrower and Bank to have all such Obligations secured by the first priority perfected security interest in the Collateral granted herein (subject only to Permitted Liens that expressly or by operation of law have superior priority to Bank’s
Lien in this Agreement). 
 If this Agreement is terminated, Bank’s Lien in the Collateral shall continue until the
Obligations (other than inchoate indemnity obligations) are satisfied in full, and at such time, Bank shall, at Borrower’s sole cost and expense, terminate its security interest in the Collateral and all rights therein shall revert to Borrower.
In the event (a) all Obligations (other than inchoate indemnity obligations), except for Bank Services, are satisfied in full, and (b) this Agreement is terminated, Bank shall terminate the security interest granted herein upon Borrower
providing cash collateral acceptable to Bank in its good faith business judgment for Bank Services, if any. In the event such Bank Services consist of outstanding letters of credit, Borrower shall provide to Bank cash collateral in an amount equal
to 105% (110% for letters of credit denominated in a currency other than Dollars), of the Dollar Equivalent of the face amount of all such letters of credit plus all interest, fees, and costs due or to become due in connection therewith (as
estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to such letters of credit. 

4.2 Priority of Security Interest. Borrower 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 that expressly or by operation of law have superior priority to Bank’s Lien under this Agreement). If Borrower
shall acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms
of this Agreement, with such writing to be in form and substance reasonably satisfactory to Bank. 
 Notwithstanding the
foregoing, Bank’s security interest in the assets of Borrower securing the Obligations of Borrower to Bank under this Agreement shall be junior and subordinate to Bank’s security interest in the assets of Borrower securing the Obligations
of Borrower under the Senior Loan Agreement. 
 4.3 Authorization to File Financing Statements. Borrower hereby
authorizes Bank to file financing statements, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either
Borrower or any other Person, may be deemed to violate the rights of Bank 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 Bank’s discretion. 
 4.4 Subsequent Security. At any time following the
Effective Date, the Bank may, in its sole discretion, require any Subsidiary to grant the Bank such further security interests over their present and future undertaking and assets as the Bank may require, including for the avoidance of doubt, a
fixed charge over all book and other debts and monetary claims due or owing or incurred to any Subsidiary, including all accounts with banks and the moneys deposited therein and interest accruing and arrears and claims arising in respect of
accounts, together with the full benefit of all guarantees and securities therefore and indemnities in respect thereof and all liens, reservations of title, rights of tracing and other rights enabling any Subsidiary to enforce any such debts or
claims.

 5 REPRESENTATIONS AND WARRANTIES 

Borrower represents and warrants as follows: 
 5.1 Due Organization; Authorization; Power and Authority. Borrower and each of its Subsidiaries are duly existing and in good standing, as a Registered Organization in its jurisdiction of formation
and each is qualified and licensed to do business and each is in good standing in any jurisdiction in which the conduct of each 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 effect on Borrower’s business, taken as a whole. In connection with this Agreement, Borrower has delivered to Bank completed certificates signed by each Borrower and Guarantor, respectively,
entitled “Perfection Certificate”. Borrower represents and warrants to Bank 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, its chief executive office as well as Borrower’s mailing address (if different than its chief executive office);
(e) except as set forth in the Perfection Certificate, Borrower (and each of its predecessors) has not, in the five (5) years immediately preceding the Effective Date, 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 each of its Subsidiaries is accurate and complete in all material respects (it
being understood and agreed that Borrower may from time to time update certain information in the Perfection Certificate after the Effective Date to the extent the event of change reflected in such updated Perfection Certificate is not prohibited by
one or more specific provisions in this Agreement, and upon written notification by Borrower to Bank of such event or change, the Perfection Certificate shall be deemed to have been updated to include such information). If Borrower is not now a
Registered Organization but later becomes one, Borrower shall promptly notify Bank of such occurrence and provide Bank 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 material
order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower 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) 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 reasonably be expected to have a material adverse effect on Borrower’s
business, taken as a whole. 
 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 hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no deposit accounts other than the deposit accounts with Bank, the deposit accounts, if any described
in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice and taken such actions as are necessary to give Bank a perfected security interest therein. The Accounts are bona fide, existing
obligations of the Account Debtors. 
 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 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 with an aggregate value in excess of $50,000 to a bailee, and such bailee and Bank are not already parties to a bailee agreement covering both
the Collateral and the location where the Collateral will be stored, then Borrower will first receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in form and substance satisfactory to Bank in its sole
discretion. The provisions of this paragraph shall not apply to Demonstration Systems delivered to Borrower’s customers or prospective customers in the ordinary course of business.

 All Inventory is in all material respects of good and marketable quality, free from material
defects. 
 Borrower is the sole owner of the Intellectual Property which it owns or purports to own except for
(a) non-exclusive licenses granted to its customers in the ordinary course of business, (b) over-the-counter software that is commercially available to the public, and (c) material Intellectual Property licensed to Borrower and noted
on the Perfection Certificate. Each Patent which it owns or purports to own and which is material to Borrower’s business, taken as a whole, is valid and enforceable, and no part of the Intellectual Property which Borrower owns or purports to
own and which is material to Borrower’s business, taken as a whole, 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 have a material adverse effect on Borrower’s business, taken as a whole. 
 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 for those actions or proceedings disclosed to Bank in writing, 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, individually or in the aggregate, Two Hundred Fifty Thousand Dollars ($250,000.00). 
 5.4 Financial Condition. All consolidated financial statements for Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s consolidated
financial condition and Borrower’s consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Bank.

 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 effect on Borrower’s business, taken as a whole. 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. 
 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 Borrower
has timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower. 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 Bank in writing of the commencement of, and any material development in, the proceedings, (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 

  
 -6-









 
present pension, profit sharing and deferred compensation plans in accordance with their terms, 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. 
 5.9 Use of Proceeds. Borrower shall use the proceeds of the Credit
Extensions as working capital and to fund its general business requirements and not for personal, family, household or agricultural purposes. 
 5.10 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, as of the date such representation, warranty, or
other statement was made, taken together with all such written certificates and written statements given to Bank, 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 Bank 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). 
 5.11 Definition of
“Knowledge.” For purposes of the Loan Documents, whenever a representation or warranty is made to Borrower’s knowledge or awareness, to the “best of” Borrower’s knowledge, or with a similar qualification, knowledge
or awareness means the actual knowledge, after reasonable investigation, of the Responsible Officers.

(10) day period or cannot after diligent attempts by Borrower be cured within 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 be deemed an Event of Default (but no Credit Extensions shall be made during such cure period). Cure

 9 BANK’S RIGHTS AND
REMEDIES 
 9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, 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 Bank); 
 (b) stop
advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank; 
 (c) for any letters of credit, demand that Borrower (i) deposit cash with Bank in an amount equal to 105% (110% for letters of credit issued in a currency other than Dollars), of the Dollar
Equivalent of the aggregate face amount of all letters of credit remaining undrawn plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good faith business judgment), to secure all of the
Obligations relating to such letters of credit, as collateral security for the repayment of any future drawings under such letters of credit, and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all letter of
credit fees scheduled to be paid or payable over the remaining term of any letters of credit; provided, however, if an Event of Default described in Section 8.5 occurs, the obligation of Borrower to cash collateralize all letters
of credit remaining undrawn shall automatically become effective without any action by Bank; 
 (d) terminate any foreign
exchange forward contracts; 
 (e) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and
in any order that Bank considers advisable, notify any Person owing Borrower money of Bank’s security interest in such funds, and verify the amount of such account; 
 (f) 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 Bank requests
and make it available as Bank designates. Bank 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 Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies; 

(g) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or
for the credit or the account of Borrower; 
 (h) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale,
advertise for sale, and sell the Collateral. Bank 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, 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 Bank’s exercise of its rights under this
Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; 

  
 -15-









 (i) place a “hold” on any account maintained with Bank 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; 
 (j) demand and receive possession of Borrower’s Books; and 
 (k) exercise all
rights and remedies available to Bank 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 Bank 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 Bank 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 Bank or a third party as the Code permits. Borrower hereby appoints Bank as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection
of Bank’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations have been satisfied in full and Bank is under no further obligation to make Credit Extensions hereunder. Bank’s
foregoing appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, being coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide
Credit Extensions terminates. 
 9.3 Protective Payments. If Borrower fails to obtain the insurance called for by
Section 6.7 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, Bank may obtain such insurance or make such payment, and all amounts so paid by
Bank are Bank Expenses and immediately due and payable, bearing interest at the then highest rate applicable to the Obligations, and secured by the Collateral. Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such
insurance at the time it is obtained or within a reasonable time thereafter. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 

9.4 Application of Payments and Proceeds. If an Event of Default has occurred and is continuing, Bank 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 Bank shall determine in its sole
discretion. Any surplus shall be paid to Borrower or to other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, 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, Bank 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 Bank of cash therefor. 
 9.5 Bank’s Liability for Collateral. So long as
Bank complies with reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of Bank, Bank 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. Borrower bears all risk of loss, damage or destruction of the Collateral.

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

9.8 Borrower Liability. Any Borrower may, acting singly, request Credit Extensions hereunder. Each Borrower hereby appoints the
other as agent for the other for all purposes hereunder, including with respect to requesting Credit Extensions hereunder. Each Borrower hereunder shall be jointly and severally obligated to repay all Credit Extensions made hereunder, regardless of
which Borrower actually receives said Credit Extension, as if each Borrower hereunder directly received all Credit Extensions. Each Borrower waives (a) any suretyship defenses available to it under the Code or any other applicable law, and
(b) any right to require Bank to: (i) proceed against any Borrower or any other person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank 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, so
long as any Obligation remains outstanding, each Borrower irrevocably subordinates in priority and payment to the indefeasible repayment in full in cash of the Obligations all rights that it may have at law or in equity (including, without
limitation, any law subrogating Borrower to the rights of Bank 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 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 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 Bank and such payment shall be promptly delivered to Bank for application to the Obligations, whether
matured or unmatured.

 11 CHOICE OF LAW, VENUE, AND JURY TRIAL WAIVER 

New York law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive
jurisdiction of the State and Federal courts in New York; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank 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 Bank. 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. NOTWITHSTANDING ANYTHING TO THE CONTRARY SET FORTH HEREINABOVE, BANK SHALL SPECIFICALLY HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK
DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANK’S RIGHTS AGAINST BORROWER OR ITS PROPERTY. 
 TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK 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 BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

discretion). Bank has the right, without the consent of or notice to Borrower, to sell, transfer, assign, negotiate, or grant participation in all or any

part of, or any interest in, Bank’s obligations, rights, and benefits under this Agreement and the other Loan Documents (other than the Warrants, as to which assignment, transfer and other
such actions are governed by the terms of the Warrants). In addition and without limiting the foregoing, Bank may elect to participate all or a portion of its interest under this Agreement to any Person; provided, however, the
documentation of such participation shall be at no cost to Borrower.

indemnify, defend and hold Bank and its directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Bank (each, an “Indemnified Person”) harmless against: (a) all obligations, demands,

 12.7 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 enforceable or admissible unless, and only to the extent, expressly set forth in a writing signed by the party against which
enforcement or admission is sought. 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 between the parties about the subject matter of the Loan Documents merge into the Loan Documents. 
 12.8 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and

Agreement) have been paid in full and satisfied. Without limiting the foregoing, except as otherwise provided in Section 4.1, the grant of security interest by Borrower in Section 4.1 shall survive until the termination of all Bank
Services Agreements. The obligation of Borrower in Section 12.3 to indemnify Bank shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

this provision); (c) as required by law, regulation, subpoena, or other order; (d) to Bank’s regulators or as otherwise required in connection with Bank’s examination or audit; (e) as Bank considers appropriate in exercising
remedies under the Loan Documents; and (f) to third-party service providers of Bank so long as such service providers have executed a confidentiality agreement with Bank with terms no less restrictive than those contained
herein. Confidential information does not include information that is either: (i) in the public domain or in Bank’s possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank; or

apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO
ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.
