Other Defaults.

Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower’s or any Grantor’s property or Borrower’s or any Grantor’s ability to repay the Loans or perform their respective obligations under this Agreement or any of the Related Documents.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower’s behalf under this Agreement or the Related Documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency. The dissolution or termination of Borrower’s existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower’s property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Defective Collateralization. This Agreement or any of the Related Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time and for any reason.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the Loan. This includes a garnishment of any of Borrower’s accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any Guarantor of any of the Indebtedness or any Guarantor dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any Guaranty of the Indebtedness.

execution.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where otherwise provided in this Agreement or the Related Documents, all commitments and obligations of Lender under this Agreement or the Related Documents or any other agreement immediately will terminate (including any obligation to make further Loan Advances or disbursements), and, at Lender’s option, all indebtedness immediately will become due and payable, all without notice of any kind to Borrower, except that in the case of an Event of Default of the type described in the “Insolvency” subsection above, such acceleration shall be automatic and not optional.

Except as may be prohibited by applicable law, all of Lender’s rights and remedies shall be cumulative and may be exercised singularly or concurrently. Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Borrower or of any Grantor shall not affect Lender’s right to declare a default and to exercise its rights and remedies.

Limitations on Senior Funded Indebtedness. Borrower shall not after the date hereof, create, incur or assume, directly or indirectly, any additional Senior Funded Indebtedness other than Senior Funded Indebtedness owed or to be owed to Lender.

Mergers. Borrower shall not liquidate or dissolve, merge or consolidate with or into, or acquire any other business organization, provided however, that this requirement shall not apply to transactions in which Borrower is the surviving entity.

Borrower shall not make any loans or advances to any individual, partnership, corporation, limited liability company, trust, or other organization or person, including without limitation its officers and employees; provided, however, that Borrower may make advances to its employees, including its officers, with respect to expenses incurred or to be incurred by such employees in the ordinary course of business which expenses are reimbursable by Borrower; and provided further, however, that Borrower may extend credit in the ordinary course of business in accordance with customary trade practices.

Sale of Assets. Borrower shall not sell, lease or otherwise dispose of any of its assets, except in the ordinary course of business and except for the purpose of replacing machinery, equipment or other personal property which, as a consequence of wear, duplication or obsolescence, is no longer used or necessary in the Borrower’s business, provided that full, fair and reasonable consideration is received therefor; provided, however, in no event shall the Borrower sell, lease or otherwise dispose of any equipment purchased with the proceeds of any loans made by the Lender.

Attorneys’ Fees; Expenses. Borrower agrees to pay upon demand all of Lender’s costs and expenses, including Lender’s attorneys’ fees and Lender’s legal expenses, incurred in connection with the enforcement of this Agreement.

Borrower additionally waives any and all notices of sale of participation interests, as well as all notices of any repurchase of such participation interests. Borrower also agrees that the purchasers of any such participation interests will be considered as the absolute owners of such interests in the Loan and will have all the rights granted under the participation agreement or agreements governing the sale of such participation interests. Borrower further waives all rights of offset or counterclaim that it may have now or later against Lender or against any purchaser of such a participation interest and unconditionally agrees that either Lender or such purchaser may enforce Borrower’s obligation under the Loan irrespective of the failure or insolvency of any holder of any interest in the Loan. Borrower further agrees that the purchaser of any such participation interests may enforce its interests irrespective of any personal claims or defenses that Borrower may have against Lender.

Governing Law. This Agreement will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California without regard to its conflicts of law provisions. This Agreement has been accepted by Lender in the State of California.

Loan No: MASTER BUSINESS LOAN AGREEMENT (Continued) Page 7

No Waiver by Lender. Lender shall not be deemed to have waived any rights under this Agreement unless such waiver is given in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A waiver by Lender of a provision of this Agreement shall not prejudice or constitute a waiver of Lender’s right otherwise to demand strict compliance with that provision or any other provision of this Agreement. No prior waiver by Lender, nor any course of dealing between Lender and Borrower, or between Lender and any Grantor, shall constitute a waiver of any of Lender’s rights or of any of Borrower’s or any Grantor’s obligations as to any future transactions. Whenever the consent of Lender is required under this Agreement, the granting of such consent by Lender in any instance shall not constitute continuing consent to subsequent instances where such consent is required and in all cases such consent may be granted or withheld in the sole discretion of Lender.

Notices. Any notice required to be given under this Agreement shall be given in writing, and shall be effective when actually delivered, when actually received by telefacsimile (unless otherwise required by law), when deposited with a nationally recognized overnight courier, or, if mailed, when deposited in the United States mail, as first class, certified or registered mail postage prepaid, directed to the addresses shown near the beginning of this Agreement. Any party may change its address for notices under this Agreement by giving formal written notice to the other parties, specifying that the purpose of the notice is to change the party’s address. For notice purposes, Borrower agrees to keep Lender informed at all times of Borrower’s current address. Unless otherwise provided or required by law, if there is more than one Borrower, any notice given by Lender to any Borrower is deemed to be notice given to all Borrowers.

Severability. If a court of competent jurisdiction finds any provision of this Agreement to be illegal, invalid, or unenforceable as to any circumstance, that finding shall not make the offending provision illegal, invalid, or unenforceable as to any other circumstance. If feasible, the offending provision shall be considered modified so that it becomes legal, valid and enforceable. If the offending provision cannot be so modified, it shall be considered deleted from this Agreement. Unless otherwise required by law, the illegality, invalidity, or unenforceability of any provision of this Agreement shall not affect the legality, validity or enforceability of any other provision of this Agreement.

Subsidiaries and Affiliates of Borrower. To the extent the context of any provisions of this Agreement makes it appropriate, including without limitation any representation, warranty or covenant, the word “Borrower” as used in this Agreement shall include all of Borrower’s subsidiaries and affiliates. Notwithstanding the foregoing however, under no circumstances shall this Agreement be construed to require Lender to make any Loan or other financial accommodation to any of Borrower’s subsidiaries or affiliates.

Successors and Assigns. All covenants and agreements by or on behalf of Borrower contained in this Agreement or any Related Documents shall bind Borrower’s successors and assigns and shall inure to the benefit of Lender and its successors and assigns. Borrower shall not, however, have the right to assign Borrower’s rights under this Agreement or any interest therein, without the prior written consent of Lender.

Survival of Representations and Warranties. Borrower understands and agrees that in extending Loan Advances, Lender is relying on all representations, warranties, and covenants made by Borrower in this Agreement or in any certificate or other instrument delivered by Borrower to Lender under this Agreement or the Related Documents. Borrower further agrees that regardless of any investigation made by Lender, all such representations, warranties and covenants will survive the extension of Loan Advances and delivery to Lender of the Related Documents, shall be continuing in nature, shall be deemed made and redated by Borrower at the time each Loan Advance is made, and shall remain in full force and effect until such time as Borrower’s Indebtedness shall be paid in full, or until this Agreement shall be terminated in the manner provided above, whichever is the last to occur.

Time is of the Essence. Time is of the essence in the performance of this Agreement.

Jury Waiver. To the extent permitted by applicable law, all parties to this Agreement hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by any party against any other party.

Judicial Reference Provision. In the event the above Jury Waiver is unenforceable, the parties elect to proceed under this Judicial Reference Provision. With the exception of the items specified below, any controversy, dispute or claim between the parties relating to (1) the instrument, document or other agreement in which this Judicial Reference Provision appears or (2) any related documents, instruments or transactions between the parties (each, a “Claim”), will be resolved by a reference proceeding in California pursuant to Sections 638 et seq. of the California Code of Civil Procedure, or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to reference. Venue for the reference will be the Superior Court in the County where real property involved in the action, if any, is located, or in a County where venue is otherwise appropriate under law (the “Court”). The following matters shall not be subject to reference: (1) nonjudicial foreclosure of any security interests in real or personal property, (2) exercise of self-help remedies (including without limitation set-off), (3) appointment of a receiver, and (4) temporary, provisional or ancillary remedies (including without limitation writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). The exercise of, or opposition to, any of the above does not waive the right to a reference hereunder.

The referee shall be selected by agreement of the parties. If the parties do not agree, upon request of any party a referee shall be selected by the Presiding Judge of the Court. The referee shall determine all issues in accordance with existing case law and statutory law of the State of California, including without limitation the rules of evidence applicable to proceedings at law. The referee is empowered to enter equitable and legal relief, and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision, and pursuant to CCP §644 the referee’s decision shall be entered by the Court as a judgment or order in the same manner as if tried by the Court. The final judgment or order from any decision or order entered by the referee shall be fully appealable as provided by law. The parties reserve the right to findings of fact, conclusions of law, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial if granted will be a reference hereunder. AFTER CONSULTING (OR HAVING THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, EACH PARTY AGREES THAT ALL CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT A JURY.

Principal Amount: $2,500,000.00 Date of Note: May 6, 2015

PROMISE TO PAY. ONE STOP SYSTEMS, INC. (“Borrower”) promises to pay to BANK OF THE WEST (“Lender”), or order, in lawful money of the United States of America, the principal amount of Two Million Five Hundred Thousand & 00/100 Dollars ($2,500,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on June 1, 2016. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning June 1, 2015, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any unpaid collection costs; and then to any late charges. Borrower will pay Lender at Lender’s address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the fixed rate quoted by the Lender for successive 1 day LIBOR Interest Periods. “LIBOR Interest Periods” means a period of 1 day, determined and adjusted by Lender in accordance with the custom and practice for transactions in Eurodollars conducted in London, England. Such interest rate shall be equivalent to Lender’s LIBOR Rate which is that rate determined by Lender’s Treasury Desk to be the rate for deposits in U.S. Dollars for such period which appears on the Bloomberg Screen B TMM Page under the heading “LIBOR Fix BBAM<GO>” as of 11:00 a.m. (London time) (the “LIBOR Rate” or the “Index”) (the “Index”). The Index is not necessarily the lowest rate charged by Lender on its loans. If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower. Lender will tell Borrower the current Index rate upon Borrower’s request. The interest rate change will not occur more often than each day. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 0.120% per annum. Interest on the unpaid principal balance of this Note will be calculated as described in the “INTEREST CALCULATION METHOD” paragraph using a rate of 2.750 percentage points over the Index, resulting in an initial rate of 2.870%. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Except for the foregoing, Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: BANK OF THE WEST, SME BBC San Diego #00181, 4180 La Jolla Village Drive, Suite 405, La Jolla, CA 92037.

LATE CHARGE. If a payment is 15 days or more late, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment.

INTEREST AFTER DEFAULT. Upon default, the interest rate on this Note shall, if permitted under applicable law, immediately increase by adding an additional 5.000 percentage point margin (“Default Rate Margin”). The Default Rate Margin shall also apply to each succeeding interest rate change that would have applied had there been no default.

DEFAULT. Each of the following shall constitute an event of default (“Event of Default”) under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower’s property or Borrower’s ability to repay this Note or perform Borrower’s obligations under this Note or any of the related documents.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower’s behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency. The dissolution or termination of Borrower’s existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower’s property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrower’s accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Loan No: 0000000026 PROMISSORY NOTE (Continued) Page 2

Events Affecting Guarantor. Any of the preceding events occurs with respect to any Guarantor of any of the indebtedness or any Guarantor dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note.

Change In Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change. A material adverse change occurs in Borrower’s financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Insecurity. Lender in good faith believes itself insecure.

LENDER’S RIGHTS. Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount.

ATTORNEYS’ FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrower does not pay. Borrower will pay Lender that amount. This includes, subject to any limits under applicable law, Lender’s attorneys’ fees and Lender’s legal expenses, whether or not there is a lawsuit, including attorneys’ fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. Borrower also will pay any court costs, in addition to all other sums provided by law.

JURY WAIVER. To the extent permitted by applicable law, Lender and Borrower hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by either Lender or Borrower against the other.

JUDICIAL REFERENCE PROVISION. In the event the above Jury Waiver is unenforceable, the parties elect to proceed under this Judicial Reference Provision. With the exception of the items specified below, any controversy, dispute or claim between the parties relating to (1) the instrument, document or other agreement in which this Judicial Reference Provision appears or (2) any related documents, instruments or transactions between the parties (each, a “Claim”), will be resolved by a reference proceeding in California pursuant to Sections 638 et seq. of the California Code of Civil Procedure, or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to reference. Venue for the reference will be the Superior Court in the County where real property involved in the action, if any, is located, or in a County where venue is otherwise appropriate under law (the “Court”). The following matters shall not be subject to reference: (1) nonjudicial foreclosure of any security interests in real or personal property, (2) exercise of self-help remedies (including without limitation set-off), (3) appointment of a receiver, and (4) temporary, provisional or ancillary remedies (including without limitation writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). The exercise of, or opposition to, any of the above does not waive the right to a reference hereunder.

The referee shall be selected by agreement of the parties. If the parties do not agree, upon request of any party a referee shall be selected by the Presiding Judge of the Court. The referee shall determine all issues in accordance with existing case law and statutory law of the State of California, including without limitation the rules of evidence applicable to proceedings at law. The referee is empowered to enter equitable and legal relief, and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision, and pursuant to CCP §644 the referee’s decision shall be entered by the Court as a judgment or order in the same manner as if tried by the Court. The final judgment or order from any decision or order entered by the referee shall be fully appealable as provided by law. The parties reserve the right to findings of fact, conclusions of law, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial if granted will be a reference hereunder.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower’s accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds jointly with someone else and all accounts Borrower may open in the future. However, this does not include any IRA or Keogh accounts, or any trust accounts for which setoff would be prohibited by law. Borrower authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the indebtedness against any and all such accounts, and, at Lender’s option, to administratively freeze all such accounts to allow Lender to protect Lender’s charge and setoff rights provided in this paragraph.

Principal Amount: $1,250,000.00 Date of Note: May 6, 2015

PROMISE TO PAY. ONE STOP SYSTEMS, INC. (“Borrower”) promises to pay to BANK OF THE WEST (“Lender”), or order, in lawful money of the United States of America, the principal amount of One Million Two Hundred Fifty Thousand & 00/100 Dollars ($1,250,000.00), together with interest on the unpaid principal balance from May 6, 2015, calculated as described in the “INTEREST CALCULATION METHOD” paragraph using an interest rate of 3.600%, until paid in full. The interest rate may change under the terms and conditions of the “INTEREST AFTER DEFAULT” section.

PAYMENT. Borrower will pay this loan in 35 payments of $36,749.53 each payment and an irregular last payment estimated at $36,749.59. Borrower’s first payment is due June 15, 2015, and all subsequent payments are due on the same day of each month after that. Borrower’s final payment will be due on May 15, 2018, and will be for all principal and all accrued interest not yet paid. Payments include principal and interest. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any unpaid collection costs; and then to any late charges. Borrower will pay Lender at Lender’s address shown above or at such other place as Lender may designate in writing.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method.

PREPAYMENT FEE. Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Upon prepayment of this Note, Lender is entitled to the following prepayment fee: The undersigned may upon at least ten (10) “Business Days” notice to Lender, prepay this Note in whole or in part with accrued interest to the date of such prepayment on the amount prepaid, provided that on the date of prepayment the undersigned also pay to Lender an amount equal to one percent (1%) of the principal amount of the Note prepaid, provided however, Borrower may pay up to 20% of the aggregate annual principal amount without incurring the fee. Lender’s failure to collect the prepayment fee at the time of prepayment does not excuse the prepayment fee and Lender has the right to collect that fee at any time by notifying the undersigned of the amount owing. For purposes of this Note, the term “Business Days” shall mean any day which is not a Saturday, Sunday, or other day on which commercial banks are by law authorized or required to close. Each partial prepayment shall be applied to the outstanding principal amount of this Note in inverse order of maturity. Except for the foregoing, Borrower may pay all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments under the payment schedule. Rather, early payments will reduce the principal balance due and may result in Borrower’s making fewer payments. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: BANK OF THE WEST, SME BBC San Diego #00181, 4180 La Jolla Village Drive, Suite 405, La Jolla, CA 92037.

LATE CHARGE. If a payment is 15 days or more late, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment.

INTEREST AFTER DEFAULT. Upon default, the interest rate on this Note shall, if permitted under applicable law, immediately increase by 5.000 percentage points.

DEFAULT. Each of the following shall constitute an event of default (“Event of Default”) under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower’s property or Borrower’s ability to repay this Note or perform Borrower’s obligations under this Note or any of the related documents.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower’s behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency. The dissolution or termination of Borrower’s existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower’s property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrower’s accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note.

Loan No: 0000000034 PROMISSORY NOTE (Continued) Page 2

Change In Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change. A material adverse change occurs in Borrower’s financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Insecurity. Lender in good faith believes itself insecure.

LENDER’S RIGHTS. Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount.

ATTORNEYS’ FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrower does not pay. Borrower will pay Lender that amount. This includes, subject to any limits under applicable law, Lender’s attorneys’ fees and Lender’s legal expenses, whether or not there is a lawsuit, including attorneys’ fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. Borrower also will pay any court costs, in addition to all other sums provided by law.

JURY WAIVER. To the extent permitted by applicable law, Lender and Borrower hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by either Lender or Borrower against the other.

JUDICIAL REFERENCE PROVISION. In the event the above Jury Waiver is unenforceable, the parties elect to proceed under this Judicial Reference Provision. With the exception of the items specified below, any controversy, dispute or claim between the parties relating to (1) the instrument, document or other agreement in which this Judicial Reference Provision appears or (2) any related documents, instruments or transactions between the parties (each, a “Claim”), will be resolved by a reference proceeding in California pursuant to Sections 638 et seq. of the California Code of Civil Procedure, or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to reference. Venue for the reference will be the Superior Court in the County where real property involved in the action, if any, is located, or in a County where venue is otherwise appropriate under law (the “Court”). The following matters shall not be subject to reference: (1) nonjudicial foreclosure of any security interests in real or personal property, (2) exercise of self-help remedies (including without limitation set-off), (3) appointment of a receiver, and (4) temporary, provisional or ancillary remedies (including without limitation writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). The exercise of, or opposition to, any of the above does not waive the right to a reference hereunder.

The referee shall be selected by agreement of the parties. If the parties do not agree, upon request of any party a referee shall be selected by the Presiding Judge of the Court. The referee shall determine all issues in accordance with existing case law and statutory law of the State of California, including without limitation the rules of evidence applicable to proceedings at law. The referee is empowered to enter equitable and legal relief, and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision, and pursuant to CCP §644 the referee’s decision shall be entered by the Court as a judgment or order in the same manner as if tried by the Court. The final judgment or order from any decision or order entered by the referee shall be fully appealable as provided by law. The parties reserve the right to findings of fact, conclusions of law, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial if granted will be a reference hereunder. AFTER CONSULTING (OR HAVING THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, EACH PARTY AGREES THAT ALL CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT A JURY.

GOVERNING LAW. This Note will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California without regard to its conflicts of law provisions. This Note has been accepted by Lender in the State of California.

CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender’s request to submit to the jurisdiction of the courts of San Diego County, State of California.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower’s accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds jointly with someone else and all accounts Borrower may open in the future. However, this does not include any IRA or Keogh accounts, or any trust accounts for which setoff would be prohibited by law. Borrower authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the indebtedness against any and all such accounts, and, at Lender’s option, to administratively freeze all such accounts to allow Lender to protect Lender’s charge and setoff rights provided in this paragraph.

COLLATERAL. Borrower acknowledges this Note is secured by the following collateral described in the security instruments listed herein:

(A) a life insurance policy described in an Assignment of Life Insurance Policy dated May 6, 2015.

(B) inventory, chattel paper, accounts, equipment and general intangibles described in a Commercial Security Agreement dated May 6, 2015.

FEES FOR PAYMENT OF LENDER’S OUT-OF-POCKET EXPENSES. As a condition precedent to the effectiveness of the Note, Borrower agrees to pay all of the Lender’s out-of-pocket expenses in connection with the preparation and negotiation of this Note.

SUCCESSOR INTERESTS. The terms of this Note shall be binding upon Borrower, and upon Borrower’s heirs, personal representatives, successors and assigns, and shall inure to the benefit of Lender and its successors and assigns.

GENERAL PROVISIONS. If any part of this Note cannot be enforced, this fact will not affect the rest of the Note. Lender may delay or forgo enforcing any of its rights or remedies under this Note without losing them. Borrower and any other person who signs, guarantees or endorses this Note, to the extent allowed by law, waive any applicable statute of limitations, presentment, demand for payment, and notice of dishonor. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note, whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender may renew or extend (repeatedly and for any length of time) this loan or release any party or guarantor or collateral; or impair, fail to realize upon or perfect Lender’s security interest in the collateral; and take any other action deemed necessary by Lender without the consent of or notice to anyone. All such parties also agree that Lender may modify this loan without the consent of or notice to anyone other than the party with whom the modification is made. The obligations under this Note are joint and several.

Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Upon prepayment of this Note, Lender is entitled to the following prepayment fee: The undersigned may upon at least ten (10) “Business Days” notice to Lender, prepay this Note in whole or in part with accrued interest to the date of such prepayment on the amount prepaid, provided that on the date of prepayment the undersigned also pay to Lender an amount equal to one percent (1%) of the principal amount of the Note prepaid for the first three years, and none thereafter. Lender’s failure to collect the prepayment fee at the time of prepayment does not excuse the prepayment fee and Lender has the right to collect that fee at any time by notifying the undersigned of the amount owing. For purposes of this Note, the term “Business Days” shall mean any day which is not a Saturday, Sunday, or other day on which commercial banks are by law authorized or required to close. Each partial prepayment shall be applied to the outstanding principal amount of this Note in inverse order of maturity. Except for the foregoing, Borrower may pay all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments under the payment schedule. Rather, early payments will reduce the principal balance due and may result in Borrower’s making fewer payments. Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full” of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: BANK OF THE WEST, SME BBC San Diego #00181, 4180 La Jolla Village Drive, Suite 405, La Jolla, CA 92037.

LATE CHARGE. If a payment is 15 days or more late, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment.

INTEREST AFTER DEFAULT. Upon default, the interest rate on this Note shall, if permitted under applicable law, immediately increase by 5.000 percentage points.

DEFAULT. Each of the following shall constitute an event of default (“Event of Default”) under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower’s property or Borrower’s ability to repay this Note or perform Borrower’s obligations under this Note or any of the related documents.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower’s behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency. The dissolution or termination of Borrower’s existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower’s property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrower’s accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note.

Loan No: NEW PROMISSORY NOTE (Continued) Page 2

Change In Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change. A material adverse change occurs in Borrower’s financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Insecurity. Lender in good faith believes itself insecure.

LENDER’S RIGHTS. Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount.

ATTORNEYS’ FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrower does not pay. Borrower will pay Lender that amount. This includes, subject to any limits under applicable law, Lender’s attorneys’ fees and Lender’s legal expenses, whether or not there is a lawsuit, including attorneys’ fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. Borrower also will pay any court costs, in addition to all other sums provided by law.

JURY WAIVER. To the extent permitted by applicable law, Lender and Borrower hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by either Lender or Borrower against the other.

JUDICIAL REFERENCE PROVISION. In the event the above Jury Waiver is unenforceable, the parties elect to proceed under this Judicial Reference Provision. With the exception of the items specified below, any controversy, dispute or claim between the parties relating to (1) the instrument, document or other agreement in which this Judicial Reference Provision appears or (2) any related documents, instruments or transactions between the parties (each, a “Claim”), will be resolved by a reference proceeding in California pursuant to Sections 638 et seq. of the California Code of Civil Procedure, or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to reference. Venue for the reference will be the Superior Court in the County where real property involved in the action, if any, is located, or in a County where venue is otherwise appropriate under law (the “Court”). The following matters shall not be subject to reference: (1) nonjudicial foreclosure of any security interests in real or personal property, (2) exercise of self-help remedies (including without limitation set-off), (3) appointment of a receiver, and (4) temporary, provisional or ancillary remedies (including without limitation writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). The exercise of, or opposition to, any of the above does not waive the right to a reference hereunder.

The referee shall be selected by agreement of the parties. If the parties do not agree, upon request of any party a referee shall be selected by the Presiding Judge of the Court. The referee shall determine all issues in accordance with existing case law and statutory law of the State of California, including without limitation the rules of evidence applicable to proceedings at law. The referee is empowered to enter equitable and legal relief, and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision, and pursuant to CCP §644 the referee’s decision shall be entered by the Court as a judgment or order in the same manner as if tried by the Court. The final judgment or order from any decision or order entered by the referee shall be fully appealable as provided by law. The parties reserve the right to findings of fact, conclusions of law, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial if granted will be a reference hereunder. AFTER CONSULTING (OR HAVING THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, EACH PARTY AGREES THAT ALL CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT A JURY.

GOVERNING LAW. This Note will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California without regard to its conflicts of law provisions. This Note has been accepted by Lender in the State of California.

CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender’s request to submit to the jurisdiction of the courts of San Diego County, State of California.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower’s accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds jointly with someone else and all accounts Borrower may open in the future. However, this does not include any IRA or Keogh accounts, or any trust accounts for which setoff would be prohibited by law. Borrower authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the indebtedness against any and all such accounts, and, at Lender’s option, to administratively freeze all such accounts to allow Lender to protect Lender’s charge and setoff rights provided in this paragraph.

COLLATERAL. Borrower acknowledges this Note is secured by:

(A) Commercial Security Agreement dated July 14, 2016

(B) Assignment of Life Insurance Policy dated May 6, 2015.

FEES FOR PAYMENT OF LENDER’S OUT-OF-POCKET EXPENSES. As a condition precedent to the effectiveness of the Note, Borrower agrees to pay all of the Lender’s out-of-pocket expenses in connection with the preparation and negotiation of this Note.

PRIOR NOTE. Promissory Note dated May 6, 2015 in the original principal amount of $1,250,000.00.

SUCCESSOR INTERESTS. The terms of this Note shall be binding upon Borrower, and upon Borrower’s heirs, personal representatives, successors and assigns, and shall inure to the benefit of Lender and its successors and assigns.

GENERAL PROVISIONS. If any part of this Note cannot be enforced, this fact will not affect the rest of the Note. Lender may delay or forgo enforcing any of its rights or remedies under this Note without losing them. Borrower and any other person who signs, guarantees or endorses this Note, to the extent allowed by law, waive any applicable statute of limitations, presentment, demand for payment, and notice of dishonor. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note, whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender may renew or extend (repeatedly and for any length of time) this loan or release any party or guarantor or collateral; or impair, fail to realize upon or perfect Lender’s security interest in the collateral; and take any other action deemed necessary by Lender without the consent of or notice to anyone. All such parties also agree that Lender may modify this loan without the consent of or notice to anyone other than the party with whom the modification is made. The obligations under this Note are joint and several.
