2 (d) .Prepayments Upon Change in Control. If a Change in Control has been approved by Borrower’s Board and the Change in Control transaction requires prepayment of the Obligations, then Borrower may prepay all outstanding Obligations under this Agreement in connection with such Change in Control transaction in accordance with this section, provided that Borrower delivers written notice of such Change in Control and prepayment to Lender at least thirty (30) days’ prior to such prepayment. If Borrower is not required by the Change in Control transaction and does not desire to prepay all outstanding Obligations under this Agreement in connection with such Change in Control, Borrower shall send a written notice to Lender on the earlier of (i) 30 days prior to such Change in Control or (ii) within three (3) Business Days after Borrower becomes aware that a Change in Control has occurred seeking Lender’s consent to the Change in Control. If Lender, in its reasonable discretion exercised in good faith, does not consent to such Change in Control, Lender shall give notice of such decision, and Lender may require Borrower to prepay all outstanding Obligations under this Agreement in connection with such Change in Control in accordance with this section. In the event of any prepayment of all Obligations in connection with a Change in Control described in this section, Borrower shall pay to Lender (x) all outstanding principal and accrued interest on all Credit Extensions and all other Obligations, (y) an Exit Premium with respect to each Term Loan being prepaid, and (z) scheduled interest, if any, from the date of the prepayment through twelve (12) months after the Funding Date with respect to each Working Capital Loan being prepaid. This Agreement shall be terminated upon the payment and satisfaction of all Obligations as described in this Section in connection with a Change in Control. (e) Voluntary Prepayment. Except as permitted in Section 2.2(d) and Section 2.11, Borrower may not voluntarily prepay all or any portion of any Term Loan. (f) Initial Term Loan. On or before the date thirty (30) days after the Effective Date, Lender shall make an initial Term Loan to Borrower, in a principal amount of Three Million Dollars ($3,000,000) (the “Initial Credit Extension”). 2.3 Working Capital Line. (a) Availability. Subject to the terms and conditions of this Agreement, upon Borrower’s request and no more frequently than Quarterly, Lender shall make advances to Borrower under a Working Capital Line during the Draw Period (each a “Working Capital Loan” and collectively, the “Working Capital Loans”) in an aggregate principal amount not to exceed the lesser of the Available Draw Amount or the outstanding principal balance of any Term Loans. Each Working Capital Loan shall be in increments of One Million Dollars ($1,000,000) unless otherwise approved by the Lender. Amounts borrowed under the Working Capital Line may be repaid and, during the Draw Period, reborrowed, subject to the applicable terms and conditions precedent herein. Each Working Capital Loan shall be set forth on Schedule 1 hereto. (b) Repayment. With respect to each Working Capital Loan, commencing on January 1, 2020 and continuing on each Quarter thereafter until the Working Capital Line Maturity Date for such Working Capital Loan, Borrower (i) shall make Quarterly payments to the Lender of interest, in arrears, on the principal amount of such Working Capital Loan at the rate set forth in Section 2.4 and (ii) may make the Working Capital Line Final Payment for such Working Capital Loan. Borrower shall pay to the Lender the Working Capital Line Final Payment for each Working Capital Loan on the Working Capital Line Maturity Date for such Working Capital Loan. (c) Mandatory Prepayment Upon an Acceleration. If the Working Capital Loans are accelerated by Lender following the occurrence and during the continuance of an Event of Default, Borrower shall immediately pay to Lender an amount equal to (i) the Working Capital Line Final Payment for such Working Capital Loans, plus (ii) scheduled interest, if any, from the date of acceleration until twelve (12) months after the Funding Date for each Working Capital Loan at the rate set forth in Section 2.4(a)(i), plus (iii) interest, if any and applicable, at the Default Rate with respect to any past due amounts in accordance with the terms hereof. (d) Voluntary Prepayment. Borrower may prepay any Working Capital Loan by paying all outstanding principal balance, unpaid accrued interest, and any additional scheduled interest that would have been charged through the twelve (12) months after the Funding Date on such Working Capital Loan; provided that such prepayment shall be made only on a Payment Date and provided, further, that if the prepayment of the Working

3 Capital Loan occurs pursuant to the prepayment of the Obligations as set forth in Section 2.11, then Section 2.11 shall govern such prepayment of the Working Capital Loans. 2.4 Payment of Interest on the Credit Extensions. (a) Interest Rate. (i) Working Capital Loans. The principal amount outstanding under each Working Capital Loan shall accrue interest at a per annum rate equal to fifteen percent (15.00%), which interest shall be payable Quarterly in accordance with Section 2.4(c) below. (ii) Term Loans. The principal amount outstanding under each Term Loan shall accrue interest at a per annum rate equal to fifteen percent (15.00%); provided, however, if Borrower achieves three (3) consecutive fiscal year Quarters of positive EBITDA, then the principal amount outstanding under each Term Loan shall accrue interest at a per annum rate equal to thirteen percent (13.00%) per annum commencing as of the first day of the subsequent Quarter following such third Quarter of positive EBITDA, which interest shall be payable Quarterly in accordance with Section 2.4(c) below. (b) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, all Obligations shall bear interest at a rate per annum which is five percent (5.0%) above the rate that is otherwise applicable thereto (the “Default Rate”). Fees and expenses that Borrower is required to pay pursuant to the Loan Documents (including, without limitation, Lender 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 2.4(c) 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 Lender. (c) Payment; Interest Computation. Interest is payable Quarterly on the Payment Date and shall be computed on the basis of a 365-day year for the actual number of days elapsed. In computing interest, (i) all payments received after 12:00 p.m. Mountain time on any day shall be deemed received at the opening of business on the next Business Day, and (ii) the date of the making of any 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. After each Payment Date, Lender may deliver an updated Payment Schedule to Borrower to reflect any payments made with respect to each Credit Extension and any new Credit Extensions. 2.5 Fees. Borrower shall pay to Lender a fully earned, non-refundable commitment fee of Seventy- Five Thousand Dollars ($75,000) (“Closing Fee”) on the date of funding by Lender of the Initial Credit Extension, which Closing Fee shall be paid to Lender by deducting the amount of the Closing Fee from the Initial Credit Extension. 2.6 Payments; Application of Payments; Debit of Accounts. (a) All payments to be made by Borrower under this Agreement or any other Loan Document shall be made in immediately available funds in Dollars, without setoff or counterclaim, before 12:00 p.m. Mountain time on the date when due. Payments of principal and/or interest received after 12:00 p.m. Mountain 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 there shall be no fees or accrual of interest in addition to the standard accrual of interest resulting from delay of payment until such next Business Day. (b) Lender has the exclusive right to determine the order and manner in which all payments with respect to the Obligations may be applied. Borrower shall have no right to specify the order or the accounts to which Lender shall allocate or apply any payments required to be made by Borrower to Lender or otherwise received by Lender under this Agreement when any such allocation or application is not specified elsewhere in this Agreement.

4 (c) Lender may debit any of Borrower’s Deposit Accounts for principal and interest payments or any other amounts Borrower owes Lender when due. These debits shall not constitute a set-off. 2.7 Overadvances. If, at any time, the outstanding principal amount and accrued interest that is due and payable of all outstanding Credit Extensions exceed the Borrowing Base, Borrower shall pay to Lender in cash the amount of such excess (such excess, the “Overadvance”) as set forth under Section 8.2(c)(i). Without limiting Borrower’s obligation to repay Lender any Overadvance, Borrower agrees to start paying Lender interest on the outstanding amount of any Overadvance at the Default Rate as of the end of such next Quarter until such time as no Overadvance exists. 2.8 Termination. Unless terminated earlier pursuant to this Agreement, the Credit Extensions terminate on the Loan Maturity Date, when the principal amount of all Credit Extensions, the unpaid interest thereon, and all other Obligations relating to the Working Capital Line shall be immediately due and payable, notwithstanding any Working Capital Line Maturity Date or Term Loan Maturity Date that may be later. 2.9 Withholding. Payments received by Lender from Borrower under this Agreement will be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, duties, deductions, withholdings, assessments, fees or other charges imposed by any Governmental Authority (including any interest, additions to tax or penalties applicable thereto). Specifically, however, if at any time any Governmental Authority, applicable law, regulation or international agreement requires Borrower to make any withholding or deduction from any such payment or other sum payable hereunder to Lender, Borrower hereby covenants and agrees that the amount due from Borrower with respect to such payment or other sum payable hereunder will be increased to the extent necessary to ensure that, after the making of such required withholding or deduction, Lender receives a net sum equal to the sum which it would have received had no withholding or deduction been required, and Borrower shall pay the full amount withheld or deducted to the relevant Governmental Authority. Borrower will, upon request, furnish Lender with proof reasonably satisfactory to Lender indicating that Borrower has made such withholding payment; provided, however, that Borrower need not make any withholding payment if the amount or validity of such withholding payment is contested in good faith by appropriate and timely proceedings and as to which payment in full is bonded or reserved against by Borrower. The agreements and obligations of Borrower contained in this Section 2.9 shall survive the termination of this Agreement. 2.10 Borrowing Procedures. To obtain a Credit Extension (other than the Initial Credit Extension), an Authorized Signer of Borrower must notify Lender in writing, which such notice shall be irrevocable, by delivering to Lender (i) a duly executed Initial Loan Request as required pursuant to Section 3.2(a) and (ii) an updated and duly executed Loan Request as required pursuant to Section 3.2(b); provided that Lender shall not be obligated to fund any Credit Extension requested in the updated Loan Request to the extent it is in excess of the Initial Loan Request. Borrower shall attach to each Loan Request: (i) a schedule of expected payments, (ii) Borrower’s Financial Projections, and (iii) a Borrowing Base Statement, attached as Exhibit A to Loan Request, Exhibit D, and Exhibit E, respectively. Lender may reasonably request in its discretion from Borrower before approving the Loan Request any documentation evidencing compliance with the terms set forth in this Agreement. Lender shall review each Initial Loan Request within twenty (20) days after receipt of such request (the “Review Period”) and promptly inform the Borrower in writing of the results of its review following the expiration of the Review Period. Lender shall review each updated Loan Request prior to the requested Funding Date and promptly inform the Borrower in writing of its decision to make or decline the requested Credit Extension, subject to the terms and conditions of this Agreement. 2.11 Failure to Fund Initial Additional Commitment. In the event Borrower makes an Initial Loan Request which is a reasonable request based upon prior forecasts provided by Borrower and which meets the requirements of this Agreement (including, for the avoidance of doubt, that the Borrowing Base as of the date of the Initial Loan Request and Funding Date shall exceed the outstanding Credit Extensions plus the amount requested in such Loan Request), which, if such Credit Extension were made, would require an Additional Commitment from Lender no greater than the Initial Additional Commitment, Lender must, within five (5) Business Days after the Review Period (the “Review Period Decision Deadline”) notify Borrower (an “Initial Additional Commitment Lender Election Notice”) that Lender elects to either (i) make available the entire amount of the Loan Request without any condition other than those expressly set forth in Section 3.2, in which case the Additional Commitment shall be deemed increased as such, or (ii) decline to provide the Additional Commitment. If Lender elects to decline to provide the Additional Commitment or otherwise does not provide in an Initial Additional Commitment Lender

5 Election Notice that it shall make available the entire amount of the Loan Request without any condition other than those expressly set forth in Section 3.2, then Borrower may, for a period of ninety (90) days commencing as of the Review Period Decision Deadline, prepay all outstanding Obligations under this Agreement by paying to Lender all outstanding principal and accrued interest thereon (without, for the avoidance of doubt, any prepayment penalties) and any other amounts due hereunder as of the date of such prepayment, unless Lender, prior to such prepayment, has in fact subsequently provided notice that it agrees to fund, without any condition other than as set forth in Section 3.2, the entire Initial Loan Request. During such ninety (90) day period, Borrower agrees to use good faith efforts to work with Lender to identify whether a new lender may be willing to provide a credit facility to replace such Initial Additional Commitment without prepayment of the Obligations (an “Alternative Lender”), on terms and conditions satisfactory to each of Borrower and Lender in their respective sole discretions, but under no circumstances shall Borrower be obligated to accept any financing offered by an Alternative Lender and this sentence shall not limit, restrict or otherwise vitiate Borrower’s right to prepay the Obligations as set forth above in this Section 2.11. This Agreement shall be terminated upon the payment and satisfaction of the Obligations as described in this Section 2.11. 3. CONDITIONS OF LOANS 3.1 Conditions Precedent to Initial Credit Extension. Lender’s obligation to make the Initial Credit Extension is subject to the condition precedent that Lender shall have received, in form and substance satisfactory to Lender, such documents, and completion of such other matters, as Lender may reasonably deem necessary or appropriate, including, without limitation: (a) duly executed signatures to this Agreement and the other Loan Documents; (b) duly executed signatures to the Warrants, together with a capitalization table and copies of Borrower’s equity documents, including without limitation, documents related to Borrower’s Series C financing; (c) Borrower’s Operating Documents and long-form good standing certificates certified by the Secretary of State (or equivalent agency) of Borrower’s jurisdiction of organization or formation and each jurisdiction in which Borrower is qualified to conduct business, each as of a date no earlier than ten (10) days prior to the Effective Date; (d) a secretary’s certificate of Borrower with respect to such Borrower’s Operating Documents, incumbency, specimen signatures and resolutions authorizing the execution and delivery of this Agreement and the other Loan Documents to which it is a party; (e) duly executed signatures to the completed Borrowing Resolutions for Borrower; (f) certified copies of financing statement searches dated within the last thirty (30) days, as Lender may request, accompanied by written evidence (including any UCC termination statements) that any Liens indicated in any such financing statements constitute Permitted Liens; (g) the Perfection Certificate of Borrower, together with the duly executed signature thereto; (h) a landlord’s consent in favor of Lender for each of Borrower’s leased locations containing Collateral having a value in excess of Fifty Thousand Dollars ($50,000), by the respective landlord thereof, together with the duly executed original signatures thereto; (i) Collateral Access Agreements, each of which shall have been executed by the landlord of any property at which Borrower keeps at least ten percent (10%) of its Inventory, no later than 90 days after the Effective Date; (j) evidence satisfactory to Lender that Borrower’s insurance policies and endorsements as required in Section 6.8 are in full force and effect, together with appropriate evidence showing lender loss payable, additional insured and waiver of subrogation clauses or endorsements in favor of Lender;

7 3.3 Covenant to Deliver. Borrower agrees to deliver to Lender each item required to be delivered to Lender under this Agreement as a condition precedent to any Credit Extension. Borrower expressly agrees that a Credit Extension made prior to the receipt by Lender of any such item shall not constitute a waiver by Lender of Borrower’s obligation to deliver such item, and the making of any Credit Extension in the absence of a required item shall be in Lender’s sole discretion. 3.4 [Intentionally Omitted]. 4. SECURITY INTEREST 4.1 Grant of Security Interest. Borrower hereby grants Lender, to secure the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to Lender, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof (the “Security Interest”). Lender’s Security Interest in the Collateral shall survive the termination of this Agreement and shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon Borrower’s full repayment in cash of the Obligations (other than inchoate indemnity obligations) and at such time as Lender’s obligation to make Credit Extensions has terminated, Lender shall, at the sole cost and expense of Borrower, release its Security Interest in the Collateral and all rights therein shall revert to Borrower. 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). If Borrower shall acquire a commercial tort claim, Borrower shall promptly notify Lender in a writing signed by Borrower of the general details thereof and grant to Lender 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 Lender. 4.3 Authorization to File Financing Statements. Borrower hereby authorizes Lender to file financing statements, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Lender’s Security Interest or rights hereunder, including a notice that any disposition of the Collateral in violation of this Agreement, by either Borrower or any other Person, shall be deemed to violate the rights of Lender under the Code. 5. REPRESENTATIONS AND WARRANTIES Borrower represents and warrants to Lender on the Effective Date, the date of each Credit Extension request under Section 3.2(a) and the Funding Date of each Credit Extension as follows: 5.1 Due Organization, Authorization; Power and Authority. Borrower is duly existing and in good standing as a Registered Organization in its jurisdiction of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the failure to do so could not reasonably be expected to have a Material Adverse Change. Borrower has all requisite limited liability company power to execute and deliver this Agreement and the other Loan Documents, and to carry out and perform its obligations under the terms hereof and thereof. All limited liability company action on the part of Borrower, its directors and its members necessary for the authorization, execution, delivery and performance of this Agreement and the other Loan Documents by Borrower and the performance of Borrower’s obligations hereunder and thereunder, including the issuance and delivery of the Warrants and Warrant Units have been taken. This Agreement and the other Loan Documents, when executed and delivered, will be valid and binding obligations of Borrower enforceable in accordance with their terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting enforcement of creditors’ rights, and (b) general principles of equity that restrict the availability of equitable remedies. In connection with this Agreement, Borrower has delivered to Lender a completed certificate signed by Borrower, entitled “Perfection Certificate” in the form attached hereto as Exhibit F, as may be updated in Lender’s sole discretion (the “Perfection Certificate”). Borrower represents and warrants to Lender that (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof;

The execution, delivery and performance by Borrower of this Agreement and the other Loan Documents have been duly authorized, and do not (i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any of its Subsidiaries or any of their property or assets may be bound or affected, (iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and effect), or (v) conflict with, contravene, constitute a default or breach under, or result in or permit the termination or acceleration of, any material agreement by which 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 Change. 5.2 Collateral. Borrower has good title to, rights in, and the power to transfer each item of the Collateral upon which it purports to grant a Security Interest hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no Collateral Accounts at or with any bank or financial institution other than the Collateral Accounts described in the Perfection Certificate delivered to Lender in connection herewith and which Borrower has taken such actions as are necessary to give Lender a perfected security interest therein, to the extent required pursuant to the terms of Section 6.9(b). 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 or as permitted pursuant to Section 7.2. 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. All Inventory is in all material respects of good and marketable quality, free from material defects. Neither the operations of the Borrower as currently conducted or as currently contemplated to be conducted nor any product or service of the Borrower infringes or violates any Intellectual Property of any third party. Except pursuant to a written confidentiality agreement, the Borrower has not disclosed or made available any material Borrower confidential information or trade secrets to any other person or entity. Except for end-user licenses to standard commercially available software and agreements and licenses that have been provided to the Lender, the Borrower is not a party to, or bound by, any contract, agreement or license with respect to the Intellectual Property of a third party. Except for standard end-user licenses granted by the Borrower with respect to the licensing or sale of Borrower products or services and agreements and licenses that have been provided to the Lender, the Borrower has not granted any third party any rights, options or licenses with respect to any Intellectual Property that is or was owned by the Borrower. The Borrower has not received any communication alleging, or that would put the Borrower on notice, that the Borrower is or may be infringing or violating or, by conducting its business as currently conducted, would infringe or violate any of the Intellectual Property of any other person or entity, nor is the Borrower aware of any basis therefor. There are no agreements, understandings, instruments, contracts, judgments, orders or decrees to which the Borrower is a party or by which it is bound which involve indemnification by the Borrower with respect to infringement of Intellectual Property.

9 Each person that was or is an officer or employee of the Borrower has executed a confidential information and invention assignment agreement substantially in the form(s) delivered to the Borrower. Each consultant to the Borrower that has had access to any Borrower confidential information or trade secrets has entered into an agreement containing appropriate confidentiality and invention assignment provisions. To the knowledge of the Borrower, (i) no person that is or was an officer, employee or consultant of the Borrower is in violation of any confidential information and invention assignment agreement with the Borrower and (ii) no current officer, employee or consultant of the Borrower is in violation of any prior employee contract or proprietary information agreement with any other corporation or third party. Except as noted on the Perfection Certificate or as otherwise disclosed to Lender pursuant to Section 6.11, Borrower is not a party to, nor is it bound by, any Restricted License. 5.3 Accounts Receivable. (a) For each Account included in the Borrowing Base, on the dates any Credit Extension is requested and made and on the date of delivery of any Borrowing Base Statement, such Account shall be an Eligible Account. (b) All statements made and all unpaid balances appearing in all of Borrower’s invoices, instruments and other documents evidencing the Eligible Accounts are and shall be true and correct and all such invoices, instruments and other documents, and all of Borrower’s Books are genuine and in all respects what they purport to be. All sales and other transactions underlying or giving rise to each Eligible Account shall comply in all material respects with all applicable laws and governmental rules and regulations. Borrower has no knowledge of any actual or imminent Insolvency Proceeding of any Account Debtor whose accounts are Eligible Accounts in any Borrowing Base Statement. To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Eligible Accounts are genuine, and all such documents, instruments and agreements are legally enforceable in accordance with their terms. 5.4 Litigation. There are no actions or proceedings pending or, to the knowledge of any Responsible Officer, threatened in writing by or against Borrower or any of its Subsidiaries involving more than, individually, One Hundred Thousand Dollars ($100,000); 5.5 Financial Statements; Financial Condition. All consolidated financial statements for Borrower and any of its Subsidiaries delivered to Lender fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations as of the dates and for the periods presented (except with respect to unaudited financial statements, subject to normal year-end adjustments and for the absence of footnotes). There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Lender. 5.6 Solvency. The fair salable value of Borrower’s consolidated assets (including goodwill minus disposition costs) exceeds the fair value of Borrower’s 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. 5.7 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 (a) has complied in all material respects with all Requirements of Law, and (b) has not violated any Requirements of Law the violation of which could reasonably be expected to have a Material Adverse Change. Borrower and each of its Subsidiaries have obtained all material 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. Borrower and its Subsidiaries are in compliance with all applicable Anti-Money Laundering and Anti-Terrorism Laws.

10 5.8 Environmental. (a) Borrower is in material compliance with all applicable Environmental Laws and Borrower has not Released or stored any Hazardous Materials in violation of Environmental Laws. None of Borrower or any of its Subsidiaries is obligated to remove or remediate any Hazardous Materials pursuant to any Environmental Law or any contract entered into with any other Person that has resulted or would reasonably be expected to result in a Material Adverse Change. (b) There are no actions pending or threatened against Borrower under Environmental Law and Borrower has not received any written request for information, any written notice relating to a violation or alleged violation by Borrower or any of its Subsidiaries of any Environmental Law, or any written notice that Borrower or its Subsidiaries is or may be responsible for any remedial action under any Environmental Law. 5.9 Material Contracts. Each Material Contract is a valid, binding and enforceable obligation of Borrower or its Subsidiaries, as applicable. Neither Borrower nor its Subsidiaries, and to Borrower’s knowledge, no other party to a Material Contract, is in breach in any material respect under any Material Contract, and, to Borrower’s knowledge, there does not exist any event that, with the lapse of time or the giving of notice or both, would constitute such a breach. No party to any Material Contract has (i) indicated in writing to Borrower its intention to amend or terminate an Material Contract, or (ii) made any claims against, or sought indemnification from Borrower or any of its Subsidiaries as to any matter arising under or with respect to an Material Contract, and neither Borrower nor its Subsidiaries, nor any of their respective directors, managers, members or officers, has been advised in writing that any such claims may be asserted or initiated. 5.10 Subsidiaries; Investments. Borrower does not own any stock, partnership, or other ownership interest or other equity securities except for Permitted Investments. 5.11 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required tax returns and reports (or filed valid extensions, related thereto), and Borrower has timely paid all federal and state and all material foreign and local taxes, assessments, deposits and contributions owed by Borrower except (a) to the extent such taxes are being contested in good faith by appropriate proceedings promptly instituted and diligently conducted, so long as such reserve or other appropriate provision, if any, as shall be required in conformity with IRS Guidelines shall have been made therefor, or (b) if such taxes, assessments, deposits and contributions do not, individually or in the aggregate, exceed Fifty Thousand Dollars ($50,000). To the extent Borrower defers payment of any contested taxes, Borrower shall (i) notify Lender in writing of the commencement of, and any material development in, the proceedings, and (ii) post bonds or take 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 in excess of Fifty Thousand Dollars ($50,000). Borrower has paid all amounts necessary to fund all 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. 5.12 Warrants. When issued the Warrants and the Warrant Units will be validly issued, fully paid and nonassessable, and will be free of any liens or encumbrances other than liens and encumbrances created by or imposed upon the Lender; provided, however, that the Warrants and the Warrant Units may be subject to restrictions on transfer under state and/or federal securities laws or as otherwise required by such laws at the time a transfer is proposed. The initial sale of the Warrants to Lender and the initial issuance of the Warrant Units will not be subject to any preemptive rights or rights of first refusal that have not been properly waived or complied with. The offer, sale and issuance of the Units, the Warrants and the Warrant Units will be exempt from the registration requirements of the Securities Act of 1933, as amended, and will have been registered or qualified (or are exempt from registration and qualification) under the registration, permit or qualification requirements of all applicable state securities laws.

11 5.13 Full Disclosure. No written representation, warranty or other statement of Borrower in any report, certificate, or written statement submitted to Lender, as of the date such representation, warranty, or other statement was made contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the reports, certificates, or written statements not misleading. Borrower has disclosed to Lender all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject as of the Funding Date, and all other matters known to it as of the Funding Date, that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Change. 5.14 Definition of “Knowledge.” For purposes of this Agreement and the other 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, or constructive knowledge based on a reasonable investigation, of any Responsible Officer. 6. AFFIRMATIVE COVENANTS Borrower shall do all of the following: 6.1 Government Compliance. (a) Maintain its and all its Subsidiaries’ legal existence and good standing in their respective jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a Material Adverse Change. Borrower shall comply, and have each Subsidiary comply, in all material respects, with all laws, ordinances and regulations to which it is subject. (b) Obtain all of the Governmental Approvals necessary for the performance by Borrower of its obligations under this Agreement and the other Loan Documents to which it is a party and the grant of a Security Interest to Lender in the Collateral. Borrower shall promptly provide copies of any such obtained Governmental Approvals to Lender. 6.2 Financial Statements, Reports.

Documents required to be delivered pursuant to the terms hereof (to the extent any such documents are included in materials otherwise filed with the SEC) may be delivered electronically and if so delivered, shall be deemed to have been delivered on the date on which Borrower posts such documents, or provides a link thereto, on Borrower’s website on the internet at Borrower’s website address; provided, however, Borrower shall promptly notify Lender in writing (which may be by electronic mail) of the posting of any such documents; (iii) copies of all statements, reports and notices made available to Borrower’s equity holders or to any holders of Subordinated Debt within five (5) Business Days of delivery; (iv) any legal actions pending or threatened in writing against Borrower or any of its Subsidiaries that could result in damages or costs to Borrower or any of its Subsidiaries; (v) any breach in any material respect under any Material Contract or any agreement to any amendment, modification or other change to or waiver of any of its rights under any Material Contract if such amendment, modification, change or waiver would be adverse in any material respect to the Lender; (vi) any amendment to or termination of any Collateral Access Agreement or if Borrower enters into a new Collateral Access Agreement; and (vii) such other information regarding Borrower or compliance with the terms of this Agreement or any Loan Documents as reasonably requested by Lender from time to time. Any submission by Borrower of a Compliance Statement, a Borrowing Base Statement or any other financial statement submitted to the Lender pursuant to this Section 6.2 shall be deemed to be a representation by Borrower that (i) as of the date of such Compliance Statement, a Borrowing Base Statement or other financial statement, the information and calculations set forth therein are true, accurate and correct in all material respects, (ii) as of the end of the compliance period set forth in such submission, Borrower is in complete compliance with all required covenants except as noted in such Compliance Statement, a Borrowing Base Statement or other financial statement, as applicable, (iii) as of the date of such submission, no Events of Default have occurred and are

Keep all Inventory in good and marketable condition, free from material defects. Returns and allowances between Borrower and its Account Debtors shall follow Borrower's customary practices as they exist at the Effective Date. Borrower must promptly notify Lender of all returns, recoveries, disputes and claims that on an individual basis involve more than Fifty Thousand Dollars ($50,000). 6.4 Accounts Receivable. (a) Schedules and Documents Relating to Accounts. Borrower shall deliver to Lender transaction reports and schedules of collections, as provided in Section 6.2, on Lender’s standard forms; provided, however, that Borrower’s failure to execute and deliver the same shall not affect or limit Lender’s Security Interest and other rights in all of Borrower’s Accounts, nor shall Lender’s failure to advance or lend against a specific Account affect or limit Lender’s Security Interest and other rights therein. If requested by Lender, Borrower shall furnish Lender with copies (or, at Lender’s request, originals) of all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Accounts. In addition, Borrower shall deliver to Lender, on its reasonable request, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary indorsements, and copies of all credit memos. (b) Disputes. Borrower shall promptly notify Lender of all disputes or claims relating to Accounts in excess of Fifty Thousand Dollars ($50,000) individually. Borrower may forgive (completely or partially), compromise, or settle any Account for less than payment in full, or agree to do any of the foregoing so long as (i) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of Borrower’s Business, in arm’s-length transactions, and reports the same to Lender in the regular reports provided to Lender; (ii) no Event of Default has occurred and is continuing; and (iii) after taking into account all such discounts, settlements and forgiveness, the total outstanding Credit Extensions will not exceed the Available Draw Amount. (c) Reserves. Notwithstanding any terms in this Agreement to the contrary, upon the occurrence and during the continuance of an Event of Default, Lender may hold any proceeds of the Accounts as a reserve to be applied to any Obligations regardless of whether such Obligations are then due and payable. (d) Warranty Accounting. Borrower shall maintain a warranty reserve in an amount equal to that percentage of the purchase price of all sales for which Borrower has provided a warranty to the purchaser recommended or required by Borrower’s auditor. In the event there is no warranty recommended or required by Borrower’s auditor, Borrower shall maintain a warranty reserve of at least five percent (5%) of the purchase price of all sales for which Borrower has provided a warranty to purchaser. (e) [Intentionally Omitted]. (f) No Liability. Lender shall not be responsible or liable for any shortage or discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any Account, or for settling any Account in good faith for less than the full amount thereof, nor shall Lender be deemed to be responsible for any of Borrower’s obligations under any contract or agreement giving rise to an Account. Nothing herein shall, however, relieve Lender from liability for its own gross negligence or willful misconduct.

14 6.5 Remittance of Proceeds. Except as otherwise provided in Section 6.4(c), deliver, in kind, all proceeds arising from the disposition of any Collateral in violation of Section 7.1, to Lender in the original form in which received by Borrower not later than the following Business Day after receipt by Borrower, to be applied to the Obligations (a) prior to an Event of Default, pursuant to the terms of Section 6.4(c), and (b) after the occurrence and during the continuance of an Event of Default, pursuant to the terms of Section 9.4. Borrower agrees that it will not commingle proceeds of Collateral with any of Borrower’s other funds or property, but will hold such proceeds separate and apart from such other funds and property and in an express trust for Lender. Nothing in this Section 6.5 limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement. 6.6 Taxes; Pensions. Timely file, and require each of its Subsidiaries to timely file, all required tax returns and reports and timely pay, and require each of its Subsidiaries to timely pay, all federal and state and all material foreign and local taxes, assessments, deposits and contributions owed by Borrower and each of its Subsidiaries, except for deferred payment of any taxes contested pursuant to the terms of Section 5.9, and shall deliver to Lender, on demand, appropriate certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms. 6.7 Access to Collateral; Books and Records. At reasonable times, on fifteen (15) Business Days’ notice (provided no notice is required if an Event of Default has occurred and is continuing), Lender, or its agents, shall have the right to inspect the Collateral and the right to audit and copy Borrower’s Books. The foregoing inspections and audits shall be conducted no more often than once every twelve (12) months, unless Lender, in its reasonable discretion determines that conditions warrant quarterly inspections and audits or an Event of Default has occurred and is continuing in which case such inspections and audits shall occur as often as Lender shall determine is necessary. Borrower hereby acknowledges and agrees that the Initial Audit will be conducted prior to the Initial Credit Extension, but in no event later than ninety (90) days after the Effective Date. 6.8 Insurance. (a) Keep its business and the Collateral insured for risks and in amounts standard for companies in Borrower’s industry and location and as Lender may reasonably request. Insurance policies shall be in a form, with financially sound and reputable insurance companies that are not Affiliates of Borrower, and in amounts that are satisfactory to Lender. All property policies shall have a lender’s loss payable endorsement showing Lender as the sole lender loss payee. All liability policies shall show, or have endorsements showing, Lender as an additional insured. Lender shall be named as lender loss payee and/or additional insured with respect to any such insurance providing coverage in respect of any Collateral. Commencing January 1, 2020, Borrower shall thereafter at all times carry a key man insurance policy of at least $1,000,000 for each of its then duly elected Chief Executive Officer and Chief Technology Officer. (b) Ensure that proceeds payable under any property policy are, at Lender’s option, payable to Lender on account of the Obligations. Notwithstanding the foregoing, (a) so long as no Event of Default has occurred and is continuing, Borrower shall have the option of applying the proceeds of any casualty policy toward the replacement or repair of destroyed or damaged property; provided that any such replaced or repaired property (i) shall be of equal or like value as the replaced or repaired Collateral and (ii) shall be deemed Collateral in which Lender has been granted a first priority security interest (subject to Permitted Liens), and (b) after the occurrence and during the continuance of an Event of Default, all proceeds payable under such casualty policy shall, at the option of Lender, be payable to Lender on account of the Obligations. (c) At Lender’s request, Borrower shall deliver certified copies of insurance policies and evidence of all premium payments. Each provider of any such insurance required under this Section 6.8 shall agree, by endorsement upon the policy or policies issued by it or by independent instruments furnished to Lender, that it will give Lender thirty (30) days prior written notice before any such policy or policies shall be materially altered or canceled. If Borrower fails to obtain insurance as required under this Section 6.8 or to pay any amount or furnish any required proof of payment to third persons and Lender, Lender may make all or part of such payment or obtain such insurance policies required in this Section 6.8, and take any action under the policies Lender deems prudent.

15 6.9 Borrower’s Chase Accounts. (a) (i) If AMG National Trust Bank or an Affiliate of Lender offers banking services that are substantially similar to or better than the banking services that Borrower receives from JP Morgan Chase Bank, N.A. as of the Effective Date, then prior to March 31, 2020, Borrower shall deliver to Lender evidence that Borrower’s deposit accounts with JP Morgan Chase Bank, N.A., as more fully described in the Perfection Certificate dated as of the Effective Date (the “Chase Accounts”), have been closed and the funds therein have been transferred to new deposit accounts established with AMG National Trust Bank or such Affiliate of Lender and (ii) Borrower shall, after March 31, 2020, maintain at all times all of its primary operating and other deposit accounts, cash management and excess deposit accounts, asset management accounts, primary securities/investment accounts, letters of credit and business credit cards and foreign exchange business with AMG National Trust Bank or an Affiliate of Lender if such banking services are substantially similar to or better than the banking services that Borrower would be able to receive from another banking institution. (b) In addition to and without limiting the restrictions in (a), Borrower shall provide Lender five (5) days prior written notice before establishing any Collateral Account at or with any bank or financial institution other than Lender or Lender’s Affiliates and shall maintain at all times a Control Agreement with respect to any such Collateral Accounts. 6.10 Financial Covenants.

(b) Lender may, in a reasonable amount of time after the later of (i) the end of any Quarter or (ii) the date that the Financial Projections are provided to Lender, provide notice to Borrower that Lender has determined, in its reasonable judgment, based upon the Financial Projections and the most recent information provided by Borrower to Lender pursuant to the requirements of Section 6.2, that there is a reasonable likelihood that Borrower will fail to comply with one or more of the financial covenants in Section 6.10(a) during either of the next two (2) Quarters (as reasonably determined by Lender), whereupon Borrower shall consult with Lender to develop a course of action that is reasonably acceptable to Lender to address such projected failure within ten (10) Business Days of receipt of such notice (a “Remedial Action”). Borrower shall at all times comply with any such Remedial Action. 6.11 Protection of Intellectual Property Rights. (a) (i) Protect, defend and maintain the validity and enforceability of its Intellectual Property material to Borrower’s Business; (ii) promptly advise Lender in writing of material infringements or any other event that could reasonably be expected to materially and adversely affect the value of its Intellectual Property; and (iii) not allow any Intellectual Property material to Borrower’s business to be abandoned, forfeited or dedicated to the public without Lender’s written consent. (b) Provide written notice to Lender within ten (10) days of entering or becoming bound by any Restricted License (other than over-the-counter software that is commercially available to the public). Borrower shall take such commercially reasonable steps as Lender requests to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for (i) any Restricted License to be deemed “Collateral” and for Lender to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms, in a manner enforceable under applicable law, of any such Restricted License, whether now existing or entered into in the future,

16 and (ii) Lender to have the ability in the event of a liquidation of any Collateral to dispose of such Collateral in accordance with Lender’s rights and remedies under this Agreement and the other Loan Documents. 6.12 Litigation Cooperation.

Notwithstanding and without limiting the negative covenants contained in Sections 7.3 and 7.7, at the time that Borrower forms any direct or indirect Subsidiary or acquires any direct or indirect Subsidiary after the Effective Date, Borrower shall, at Lender’s request in its sole discretion (a) cause any such new Subsidiary to provide to Lender a joinder to this Agreement to cause such Subsidiary to become a co-borrower hereunder, together with such appropriate financing statements and/or Control Agreements, all in form and substance satisfactory to Lender (including being sufficient to grant Lender a first priority Security Interest (subject to Permitted Liens) in and to the assets of such newly formed or acquired Subsidiary), (b) provide to Lender appropriate certificates and powers and financing statements, pledging all of the direct or beneficial ownership interest in such new Subsidiary, in form and substance satisfactory to Lender, (c) pledge sixty-five percent (65%) of the direct or beneficial ownership interest of any new Foreign Subsidiary directly owned by Borrower, and (d) provide to Lender all other documentation in form and substance satisfactory to Lender, including one or more opinions of counsel reasonably satisfactory to Lender, which in its opinion is appropriate with respect to the execution and delivery of the applicable documentation referred to above.

Execute any further instruments and take further action as Lender reasonably requests to perfect or continue Lender’s Security Interest in the Collateral or to effect the purposes of this Agreement. Upon Lender’s request, deliver to Lender, within five (5) Business Days after the same are requested, copies of all correspondence, reports, documents and other filings with any Governmental Authority regarding compliance with or maintenance of Governmental Approvals or Requirements of Law or that could reasonably be expected to have a material effect on any of the Governmental Approvals or otherwise on the operations of Borrower or any of its Subsidiaries. 6.15 Use of Proceeds. The Initial Credit Extension shall be used first to repay the GreenLine Loan in its entirety. Otherwise, Borrower shall use the proceeds of the Credit Extensions solely (a) to payoff the Shell Foundation Loan on December 31, 2020 in its entirety, and (b) as working capital, for general corporate purposes and to fund its general business requirements and not for personal, family, household or agricultural purposes. 6.16 [Intentionally Omitted]. 7.

Such cure plan may include without limitation the right, but not the obligation, to prepay first the Working Capital Loans and then the

Borrower fails or neglects to perform, keep, or observe any other term, provision, condition, covenant or agreement contained in this Agreement or the Loan Documents, and as to any default (other than those specified in this Section 8) under such other term, provision, condition, covenant or agreement that can be cured, has failed to either (i) submit a cure plan to Lender within ten (10) Business Days after the occurrence thereof, or (ii) cure the default within twenty (20) Business Days after the occurrence thereof (but no Credit Extensions shall be made during such cure period). Cure periods provided under this Section 8.2(d) shall not apply to any other covenants set forth in clauses (a) through (c) above; 8.3 Investor Abandonment. If Borrower violates the covenants under Section 6.10(a)(ii) or (iii), subject to the applicable cure periods, and Borrower fails to provide to Lender copies of written commitments from investors of Borrower evidencing the commitment of such investors to continue to fund the Borrower in the amounts and timeframe necessary to enable Borrower to satisfy the Obligations as they become due and payable, as set forth more fully in the cure plan set forth in Section 8.2; 8.4 Attachment; Levy; Restraint on Business.

There is, under any agreement to which Borrower or any Guarantor is a party with a third party or parties, (a) any default resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount individually or in the aggregate in excess of One Hundred Thousand Dollars ($100,000) within the next Quarter; or (b) any breach or default by Borrower or Guarantor, the result of which could reasonably be expected to have a material adverse effect on Borrower’s or any Guarantor’s business; 8.7 Judgments; Penalties. One or more fines, penalties or final judgments, orders or decrees for the payment of money in an amount, individually or in the aggregate, of at least One Hundred Thousand Dollars ($100,000) (not covered by independent third-party insurance as to which liability has been accepted by such insurance carrier) shall be rendered against Borrower by any Governmental Authority, and the same are not, within ten (10) Business Days after the entry, assessment or issuance thereof, discharged, satisfied, or paid, or after

20 execution thereof, stayed or bonded pending appeal, or such judgments are not discharged prior to the expiration of any such stay (provided that no Credit Extensions will be made prior to the satisfaction, payment, discharge, stay, or bonding of such fine, penalty, judgment, order or decree); 8.8 Misrepresentations. Borrower or any Person acting for Borrower makes any material representation, warranty, omission or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Lender or to induce Lender to enter this Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect or misleading in any material respect when made; 8.9 Subordinated Debt. Any document, instrument, or agreement evidencing any Subordinated Debt shall for any reason be revoked or invalidated or otherwise cease to be in full force and effect, any Person shall be in breach thereof or contest in any manner the validity or enforceability thereof or deny that it has any further liability or obligation thereunder, or the Obligations shall for any reason be subordinated or shall not have the priority contemplated by this Agreement or any applicable subordination or intercreditor agreement; 8.10 Security Interest Priority. There is a material impairment in the priority of Lender's Security Interest in the Collateral; 8.11 Material Adverse Change.

Any two (2) Key Persons within six (6) months depart from or cease to be employed by Borrower, unless Borrower has obtained Lender’s prior written approval; or 8.13 Lender Board Seat.

Upon the occurrence and during the continuance of an Event of Default, Lender 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 Lender); (b) stop advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Lender; (c) verify the amount of, demand payment of and performance under, and collect any Accounts and General Intangibles, settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Lender considers advisable, and notify any Person owing Borrower money of Lender’s Security Interest in such funds. Borrower shall collect all payments in trust for Lender and, if requested by Lender, immediately deliver the payments to Lender in the form received from the Account Debtor, with proper endorsements for deposit; (d) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its Security Interest in the Collateral. Borrower shall assemble the Collateral if Lender requests and make it available as Lender designates. Lender 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 Lender a license to enter and occupy any of its premises, without charge, to exercise any of Lender’s rights or remedies;

21 (e) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) amount held by Lender owing to or for the credit or the account of Borrower; (f) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral; (g) place a “hold” on any Account maintained with Lender and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral; (h) demand and receive possession of Borrower’s Books; and (i) exercise all rights and remedies available to Lender under this Agreement and the other Loan Documents or at law or equity, including without limitation 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 Lender as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuation of an Event of Default, to: (a) endorse Borrower’s name on any checks, payment instruments, 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) demand, collect, sue, and give releases to any Account Debtor for monies due, settle and adjust disputes and claims about the Accounts directly with Account Debtors, and compromise, prosecute, or defend any action, claim, case, or proceeding about any Collateral (including filing a claim or voting a claim in any bankruptcy case in Lender’s or Borrower’s name, as Lender chooses); (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, or other 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 Lender or a third party as the Code permits. Borrower hereby appoints Lender as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Lender’s Security Interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than inchoate indemnity obligations) have been satisfied in full and the Loan Documents have been terminated. Lender’s foregoing appointment as Borrower’s attorney in fact, and all of Lender’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed and the Loan Documents have been terminated. 9.3 Protective Payments. If Borrower fails to obtain and maintain the insurance required under Section 6.8 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 Loan Document or which may be required to preserve the Collateral, Lender may obtain such insurance or make such payment, and all amounts so paid by Lender are Lender Expenses and immediately due and payable, bearing interest at the then highest rate applicable to the Obligations, and secured by the Collateral. Lender will make reasonable efforts to provide Borrower with notice of Lender obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Lender are deemed an agreement to make similar payments in the future or Lender’s waiver of any Event of Default. 9.4 Application of Payments and Proceeds Upon Default. If an Event of Default has occurred and is continuing (or at any time on the terms set forth in Section6.4(c), regardless of whether an Event of Default exists), Lender shall have the right to apply in any order 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. Lender shall pay any surplus to Borrower by credit to the designated Deposit Account or to other Persons legally entitled thereto; Borrower shall remain liable to Lender for any deficiency. If Lender, directly or indirectly, enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Lender shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Lender of cash therefor. 9.5 Lender’s Liability for Collateral. Lender 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

22 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. Lender’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 Lender 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. Lender’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Lender has all rights and remedies provided under the Code, by law, or in equity. Lender’s exercise of one right or remedy is not an election and shall not preclude Lender from exercising any other remedy under this Agreement or other remedy available at law or in equity, and Lender’s waiver of any Event of Default is not a continuing waiver. Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence. 9.7 License. Upon the occurrence and during the continuance of an Event of Default, Lender 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. In connection with Lender’s exercise of its rights under this Section 9.7, Borrower’s rights under all licenses and all franchise agreements inure to Lender’s benefit. 9.8 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Lender on which Borrower is liable. 10.

CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE Except as otherwise expressly provided in any of the Loan Documents, Colorado law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Lender each submit to the exclusive jurisdiction of the State and Federal courts in Denver, Colorado; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Lender from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Lender. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in, or subsequently provided by Borrower in accordance with Section 10, and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND LENDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. This Section 11 shall survive the termination of this Agreement. 12. GENERAL PROVISIONS 12.1 Termination Prior to Maturity Date; Survival. All covenants, representations and warranties made in this Agreement shall continue in full force until this Agreement has terminated pursuant to its terms and all Obligations have been satisfied. So long as Borrower has satisfied the Obligations pursuant to the terms of this Agreement (other than inchoate indemnity obligations, and any other obligations which, by their terms, are to survive the termination of this Agreement), this Agreement may be terminated by Borrower, effective three (3) Business Days after written notice of termination is given to Lender. Those terms and obligations that are expressly specified in this Agreement as surviving this Agreement’s termination shall continue to survive notwithstanding this Agreement’s termination. 12.2 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations under it without Lender’s prior written consent (which may be granted or withheld in Lender’s discretion). Lender has the right, upon at least ten (10) Business Days’ notice to Borrower and without the consent of Borrower, to sell, transfer, assign, negotiate, or grant participation in (a) all the Obligations, or (b) any part of the Obligations comprising principal equal to at least Two Million Dollars ($2,000,000), in each case together with the applicable portion of Lender’s obligations, rights, and benefits under this Agreement and the other Loan Documents (excluding, however, the Warrants and the Letter Agreement). 12.3 Indemnification. Borrower agrees to indemnify, defend and hold Lender and its directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Lender (each, an “Indemnified Person”) harmless against: (i) all obligations, demands, claims, and liabilities (collectively, “Claims”) claimed or asserted by any other party in connection with the transactions contemplated by this

24 Agreement and the other Loan Documents; and (ii) all losses or expenses (including Lender Expenses) in any way suffered, incurred, or paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions between Lender and Borrower contemplated by this Agreement and the other Loan Documents (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct. This Section 12.3 shall survive until all statutes of limitation with respect to the Claims, losses, and expenses for which indemnity is given shall have run. 12.4 Time of Essence. Time is of the essence for the performance and payment of all Obligations in this Agreement. 12.5 Severability of Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision. 12.6 Correction of Loan Documents. Lender may correct patent errors and fill in any blanks in the Loan Documents consistent with the agreement of the parties so long as Lender provides Borrower with written notice of such correction and allows Borrower at least ten (10) days to object to such correction. In the event of such objection, such correction shall not be made except by an amendment signed by both Lender and Borrower. 12.7 Amendments in Writing; Waiver; Integration. No purported amendment or modification of this Agreement or any Loan Document, or waiver, discharge or termination of any obligation under this Agreement or 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 this Agreement or 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. Notwithstanding the foregoing, Lender may, without any further action or consent from Borrower, (i) after each Funding Date for any Credit Extension, update Schedule 1 to reflect such Credit Extension and (ii) after each Payment Date, update Schedule 2 to reflect any payments and new Credit Extensions. This Agreement, including all Loan Documents, represents 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 all taken together, constitute one Agreement. 12.9 Confidentiality. In handling any Confidential Information, Lender shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Lender’s Subsidiaries or Affiliates (such Subsidiaries and Affiliates, together with Lender, collectively, “Lender Entities”), provided that such Subsidiaries and Affiliates are required to exercise the same degree of care as Lender; (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, Lender shall use its best efforts to obtain any prospective transferee’s or purchaser’s agreement to the terms of this provision); (c) as required by law, regulation, subpoena, or other order; (d) to Lender’s regulators or as otherwise required in connection with Lender’s examination or audit; (e) as Lender considers appropriate in exercising remedies under this Agreement; and (f) to third-party service providers of Lender so long as such service providers have executed a confidentiality agreement with Lender 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 Lender’s possession when disclosed to Lender, or becomes part of the public domain (other than as a result of its disclosure by Lender in violation of this Agreement) after disclosure to Lender; or (ii) disclosed to Lender by a third party, if Lender does not know that the third party is prohibited from disclosing the information.

25 Lender Entities may use anonymous forms of Confidential Information for aggregate datasets, for analyses or reporting, and for any other uses not expressly prohibited in writing by Borrower; provided, however, that the foregoing shall not permit Lender to utilize any information obtained by or through Lender’s representative sitting on the Board of Borrower, all such Board information deemed proprietary and private. The provisions of the immediately preceding sentence shall survive the termination of this Agreement. 12.10 Attorneys’ Fees, Costs and Expenses. Each of Borrower and Lender shall be responsible for their own costs and expenses incurred in entering into this Agreement. All Lender Expenses in connection with any amendment to this Agreement shall be borne by the Borrower, unless such amendment was required or requested by Lender. In any action or proceeding between Borrower and Lender arising out of or relating to this Agreement or the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled. 12.11 Electronic Execution of Documents. The words “execution,” “signed,” “signature” and words of like import in this Agreement and any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity and enforceability as a manually executed signature or the use of a paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act. 12.12 Right of Setoff. Borrower hereby grants to Lender a Security Interest and a right of setoff as security for all Obligations to Lender, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Lender or any entity under the control of Lender (including a subsidiary of Lender) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Lender may set off the same or any part thereof and 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 LENDER 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. 12.13 Captions. The headings used in this Agreement are for convenience only and shall not affect the interpretation of this Agreement. 12.14 Construction of Agreement.
