date at a rate per annum equal to the Base Rate plus the Applicable Rate. 
 (b)    (i) If any amount of principal

any given period is not delivered to Bank on or before the related calculation date, then Tier 1 (as indicated in the definition of “Applicable Rate”) shall apply, effective on the related calculation date until two Business
Days after such Compliance Certificate is actually received by Bank.

any period and for any reason, the actual Leverage Ratio is higher than that reported in the Compliance Certificate, Borrower shall immediately, without the requirement of notice or demand from any Person, pay to Bank an amount equal to the excess
of: (A) the amount of interest or fees that would have accrued had the Applicable Rates for the relevant period been based upon the actual Leverage Ratio for the prior period rather than the Leverage Ratio reported in the Compliance Certificate

provided hereunder equal to $350,000. Prior to the Closing Date, Borrower made a non-refundable payment to Bank of a portion of such fee in the amount of $175,000. The remaining unpaid portion of such fee in the amount of $175,000 shall be due and
payable in full on the Closing Date. 
 SECTION 2.8. COMPUTATIONS OF
INTEREST AND FEES. 
 All computations of interest for Base Rate Loans shall be made on the
basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of interest and fees hereunder shall be made on the basis of a year of 360 days and actual days elapsed. Interest shall accrue on each Loan for
the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall bear interest
for one day. Each determination by Bank of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

or charge interest rates based upon LIBOR, or any Governmental Authority has imposed material restrictions on the authority of Bank to purchase or sell, or to take deposits of, Dollars in the London interbank offered market, then, on notice thereof
by Bank to Borrower, any obligation of Bank to make or continue LIBOR Loans or to convert Revolving Credit Loans that are Base Rate Loans to LIBOR Loans shall be suspended until Bank notifies Borrower that the circumstances giving rise to such
determination no longer exist, which notification Bank shall give to Borrower promptly after Bank, it its reasonable judgment, makes such determination. Upon receipt of such first notice, Borrower shall, upon demand from Bank, prepay or, if
applicable, convert all LIBOR Loans to Base Rate Loans, either on the last day of the Interest Period therefor, if Bank may lawfully continue to maintain such LIBOR Loans to such day, or immediately, if Bank may not lawfully continue to maintain
such LIBOR Loans. Upon any such prepayment or conversion, Borrower shall also pay accrued interest on the amount so prepaid or converted and all amounts due under Section 3.4 in accordance with the terms thereof due to such prepayment or
conversion. 
  

 - 21 - 

 SECTION 3.2. INABILITY TO DETERMINE
RATES. 
 If Bank determines in connection with any request for a LIBOR Loan or a conversion to or continuation thereof that
(a) Dollar deposits are not being offered to banks in the London interbank offered market for the applicable amount and Interest Period of such LIBOR Loan, (b) adequate and reasonable means do not exist for determining LIBOR for any
requested Interest Period with respect to a proposed LIBOR Loan, or (c) LIBOR for any requested Interest Period with respect to a proposed LIBOR Loan does not adequately and fairly reflect the cost to Bank of funding such Loan, then Bank will
promptly so notify Borrower. Thereafter, the obligation of Bank to make or maintain LIBOR Loans shall be suspended until Bank revokes such notice. Upon receipt of such notice, Borrower may revoke any pending request for a Borrowing of, conversion to
or continuation of LIBOR Loans or, failing that, will be deemed to have converted such request into a request for a Revolving Credit Borrowing consisting of Base Rate Loans in the amount specified therein. 
 SECTION 3.3. INCREASED COSTS. 
 (a) Increased Costs Generally. If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against
assets of, deposits with or for the account of, or credit extended or participated in by, Bank (except any reserve requirement reflected in LIBOR); 
 (ii) subject Bank to any tax of any kind whatsoever with respect to this Agreement or any LIBOR Loan made by it, or change the basis of taxation of payments to Bank in respect thereof (except for taxes covered by
paragraph (c) below); or 
 (iii) impose on Bank or the London interbank market any other condition, cost or expense
affecting this Agreement or LIBOR Loans made by Bank; 
 and the result of any of the foregoing shall be to increase the cost to Bank of making or
maintaining any LIBOR Loan (or of maintaining its obligation to make any such Loan), or to reduce the amount of any sum received or receivable by Bank hereunder (whether of principal, interest or any other amount), then, upon request of Bank,
Borrower will pay to Bank such additional amount or amounts as will compensate Bank for such additional costs incurred or reduction suffered. 
 (b) Capital Requirements. If Bank determines that any Change in Law affecting Bank or Bank’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on Bank’s
capital or on the capital of Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by Bank, to a level below that which Bank or Bank’s holding company could have achieved but for such Change in Law (taking
into consideration Bank’s policies and the policies of Bank’s holding company with respect to capital adequacy), then from time to time Borrower will pay to Bank such additional amount or amounts as will compensate Bank or Bank’s
holding company for any such reduction suffered. 
  

 - 22 - 

 (c) Taxes. Borrower shall pay to Bank immediately upon demand, in addition to any other amounts
due or to become due hereunder, any and all withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign governmental authority and related in any manner to LIBOR. In
determining which of the foregoing are attributable to any LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower. 
 (d) Certificates for Reimbursement. A certificate of Bank setting forth the amount or amounts necessary to compensate Bank or its holding company,
as the case may be, as specified in subsection (a), (b) or (c) of this Section, as well as a reasonably detailed description of the computation of such amount and the basis for determining such amount or amounts, and delivered to Borrower
shall be conclusive absent manifest error. Borrower shall pay Bank the amount shown as due on any such certificate within ten days after receipt thereof. 
 (e) Delay in Requests. Failure or delay on the part of Bank to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of Bank’s right to demand such
compensation, provided that Borrower shall not be required to compensate Bank pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than six months prior to the date that Bank notifies
Borrower of the Change in Law giving rise to such increased costs or reductions and of Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the
six-month period referred to in this subsection shall be extended to include the period of retroactive effect thereof). 
 SECTION 3.4. COMPENSATION FOR LOSSES. 
 Upon demand of Bank from
time to time, Borrower shall promptly compensate Bank for and hold Bank harmless from any loss, cost or expense incurred by it as a result of: 
 (a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or
otherwise); or 
 (b) any failure by Borrower (for a reason other than the failure of Bank to make a Loan) to prepay, borrow, continue or
convert any Loan other than a Base Rate Loan on the date or in the amount notified by Borrower; 
 including any loss of anticipated profits and any loss or
expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. Borrower shall also pay any customary administrative fees charged
by Bank in connection with the foregoing. For purposes of calculating amounts payable by Borrower to Bank under this Section 3.4, Bank shall be deemed to have funded each LIBOR Loan made by it by a matching deposit or other borrowing in the
London interbank offered market for a comparable amount and for a comparable period, whether or not such LIBOR Loan was in fact so funded. 
  

 - 23 -

 SECTION 9.11. GOVERNING LAW. This Agreement shall be
governed by and construed in accordance with the laws of the State of California. 
 SECTION 9.12.
ARBITRATION. 
 (a) Arbitration. The parties hereto agree, upon demand by any party, to submit to binding arbitration
all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to (i) any credit
subject hereto, or any of the Loan Documents, and their negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests
for additional credit. 
 (b) Governing Rules. Any arbitration proceeding will (i) proceed in a location in California selected
by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the
parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least
$1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution
procedures or the optional procedures for large, complex commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures
set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained
herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law. 
 (c) No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration requirement does not limit the right of any party to (i) foreclose against real or personal property collateral;
(ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a
receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising
from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph. 
 (d) Arbitrator Qualifications
and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any
dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided, however, that all three arbitrators must actively participate in all hearings and deliberations. The
arbitrator will be a neutral attorney licensed in 

  

 - 38 - 

 
the State of California or a neutral retired judge of the state or federal judiciary of California, in either case with a minimum of ten years experience in
the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any
arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary
adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of California and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is
necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to
the Federal Rules of Civil Procedure, the California Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action
for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for
judicial relief. 
 (e) Discovery. In any arbitration proceeding discovery will be permitted in accordance with the Rules. All
discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date. Any requests for an extension of the discovery periods, or any discovery disputes,
will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party’s presentation and that no alternative means for obtaining information is available. 
 (f) Class Proceedings and Consolidations. No party hereto shall be entitled to join or consolidate disputes by or against others in any
arbitration, except parties who have executed any Loan Document, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of the general public or in a private attorney
general capacity. 
 (g) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration
proceeding. 
 (h) Real Property Collateral; Judicial Reference. Notwithstanding anything herein to the contrary, no dispute shall be
submitted to arbitration if the dispute concerns indebtedness secured directly or indirectly, in whole or in part, by any real property unless (i) the holder of the mortgage, lien or security interest specifically elects in writing to proceed
with the arbitration, or (ii) all parties to the arbitration waive any rights or benefits that might accrue to them by virtue of the single action rule statute of California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such indebtedness and obligations, shall remain fully valid and enforceable. If any such dispute is not submitted to arbitration, the dispute shall be referred to a referee in
accordance with California Code of Civil Procedure Section 638 et seq., and this general reference agreement is intended to be specifically enforceable in accordance with said Section 638. A referee with the qualifications required herein
for arbitrators shall be selected pursuant to the AAA’s selection procedures. Judgment upon the decision rendered by a referee shall be entered in the court in which such proceeding was commenced in accordance with California Code of Civil
Procedure Sections 644 and 645. 
  

 - 39 - 

 (i) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties
shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except
for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration
provision most directly related to the Loan Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the
parties. 
 (j) Small Claims Court. Notwithstanding anything herein to the contrary, each party retains the right to pursue in Small
Claims Court any dispute within that court’s jurisdiction. Further, this arbitration provision shall apply only to disputes in which either party seeks to recover an amount of money (excluding attorneys’ fees and costs) that exceeds the
jurisdictional limit of the Small Claims Court. 
 SECTION 9.13. NO NOVATION . This
Agreement amends and restates the Existing Agreement in its entirety, effective as of the Closing Date, and is not intended to constitute a novation of the obligations thereunder. Nothing contained herein shall terminate any security interests,
liens, guaranties or subordinations in favor of Bank and all such security interests, guaranties and subordinations shall continue in full force and effect. 
 SECTION 9.14. TERMINATION OF AGREEMENT . This Agreement shall terminate (other than with respect to contingent indemnification obligations under
Section 9.3) when all monetary Obligations (including, without limitation, the repayment of all Loans) have been satisfied in full and Bank has no further commitment to make credit extensions or accommodations under this Agreement.

 4. REMEDIES. Upon the occurrence of an Event of Default, Secured Party may declare all of the Secured Obligations to be immediately due
and payable, and Secured Party may exercise any and all rights and remedies hereunder or under applicable law; provided, however, if any Event of Default occurs as a consequence of the commencement of a bankruptcy or other insolvency
proceeding by or against Debtor, all of the Secured Obligations shall be automatically and immediately due and payable without further action or demand. Without limiting the foregoing, Secured Party shall have the right, itself or through any of its
agents, with or without notice to Debtor, as to any or all of the Collateral, by any available judicial procedure, or without judicial process (provided, however, that it is in compliance with applicable law), to exercise any and all rights
afforded to a secured party under the UCC or other applicable law, to sell or otherwise dispose of all or any part of the Collateral, either at public or private sale, in lots or in

bulk, for cash or for credit, with or without warranties or representations, and upon such terms and conditions, all as Secured Party, in its sole
discretion, may deem advisable, and it shall have the right to purchase at any such sale. Debtor agrees that a notice sent at least ten (10) days before the time of any intended public sale or of the time after which any private sale or other
disposition of the Collateral is to be made shall be reasonable notice of such sale or other disposition. The proceeds of any such sale, or other Collateral disposition shall be applied first to the expenses of retaking, holding, storing, processing
and preparing for sale, selling, and the like, and to attorneys’ fees and legal expenses of Secured Party, and then to the Secured Obligations and to the payment of any other amounts required by applicable law, after which Secured Party shall
account to Debtor for any surplus proceeds. The rights and remedies with respect to Debtor and the Collateral, whether established hereby or by any other agreements, instruments or documents or by law, shall be cumulative and may be exercised singly
or concurrently, and are not exclusive of any other rights or remedies provided under any other agreement, instrument or document to which Debtor is a party or by which it or any of the Collateral is bound or by law or equity. 
 5. LICENSE. Debtor grants to Secured Party, to the fullest extent permitted under applicable law, a fully paid and royalty free license,
exercisable only upon the occurrence and during the continuance of an Event of Default, to use any and all of the Intellectual Property Collateral as may be reasonably necessary to permit the exercise of any of Secured Party’s rights or
remedies with respect to any of the Collateral. 
 6. FURTHER ASSURANCES. Debtor will upon request promptly
execute and deliver all further instruments and documents, and take all further action that Secured Party may reasonably request in order to perfect, protect and maintain the priority of the security interest granted by this Agreement and to enable
Secured Party to exercise and enforce its rights and remedies under this Agreement. 
 7. WAIVERS. Debtor hereby waives
(a) the right to require Secured Party to proceed against any other person or against any other collateral it may hold; (b) presentment, protest and notice of protest, demand and notice of nonpayment, demand of performance, notice of sale,
and advertisement of sale, (c) following an Event of Default, any right to the benefit of or to direct the application of any of the Collateral until the obligations of Debtor shall have been paid in full, and (d) any defenses which may
arise by reason of, or be based on, lack of diligence in collection. 
 8. ATTORNEYS’ FEES. Debtor agrees
to pay the costs and expenses, including reasonable attorneys’ fees, which may be incurred by Secured Party in connection with the negotiation, administration and enforcement of this Agreement and the protection of a Secured Party’s rights
hereunder, whether or not legal action is instituted or filed. 
 9. NO WAIVER. Any acceptance of partial or
delinquent payments or failure of Secured Party to exercise any right shall not waive any obligation of Debtor or right of Secured Party or modify this Agreement or waive any similar default. 
 10. ASSIGNABILITY. Secured Party may assign its rights under this Agreement and in the Collateral to anyone at any time. This Agreement
shall be binding on Debtor and its successors and assigns, and shall benefit Secured Party and its successors and assigns.

herein and therein contain the entire security agreement between Secured Party and Debtor. This Agreement may only be amended, waived, discharged or terminated by a written instrument signed by the Company and Secured Party. 
 12. CHOICE OF LAW. This Agreement shall be governed by and construed in accordance with the laws of the
State of California, without giving effect to conflicts of law principles. 
 13. NOTICES. Except as otherwise provided, all
notices and other communications required or permitted hereunder shall be in writing, shall be effective when given, and shall in any event be deemed to be given upon receipt or, if earlier, (i) five (5) days after deposit with the U.S.
postal service or other applicable postal service, if delivered by first class mail, postage prepaid, (ii) upon delivery, if delivered by hand, (iii) one (1) business day after the day of deposit with Federal Express or similar

furnished the other in writing: 
 14. INDEMNITY. Debtor hereby indemnifies Secured Party, its principals and agents (the
“Indemnified Parties”) for, and agrees to protect and hold each of them harmless from and against, any and all liabilities, obligations, losses, damages, costs and expenses (including, without limitation, reasonable attorneys’
fees), causes of action, suits, claims, demands and judgments of any nature or description whatsoever, which may at any time be imposed upon, incurred by or awarded against any Indemnified Party (other than as a result of such Indemnified
Party’s own gross negligence or willful misconduct) as a result of the occurrence of any one or more of the following: (a) the grant to Secured Party of any interest in or to any of the Collateral, and (b) any infringement or claim of
infringement by any person or entity with respect to any of the Intellectual Property Collateral, or any claim that any of the Intellectual Property Collateral misappropriates any patent, copyright, trade secret, trademark or other intellectual
property right of any third party, or breaches any agreement of Debtor with any third party. 
 15. SEVERABILITY. If any
provision or provisions of this Agreement shall be deemed to be contrary to public policy or shall for any reason be held to be invalid, then such provision or provisions shall be deemed to be separable from the remaining provisions of this
Agreement, and shall in no way affect the validity of any of the remaining provisions of this Agreement. 
 16. HEADINGS.
Captions and headings in this Agreement are for convenience only and are not to be deemed part of this Agreement. 
 17.
COUNTERPARTS. This Agreement may be executed in counterparts, which when taken together shall constitute one document.
