1.1 Definitions. As used in this Agreement, all capitalized terms shall have the definitions set forth on Exhibit A. Any term used in the Code and not defined herein shall have the meaning given to the term in the Code.

1.2 Accounting Terms. Any accounting term not specifically defined on Exhibit A shall be construed in accordance with GAAP and all calculations shall be made in accordance with GAAP (except for non-compliance with FAS 123R in monthly reporting). The term “financial statements” shall include the accompanying notes and schedules.

2. LOAN AND TERMS OF PAYMENT.

2.1 Credit Extensions.

(a) Promise to Pay. Borrower promises to pay to Bank, in lawful money of the United States of America, the aggregate unpaid principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit Extensions at rates in accordance with the terms hereof.

(b) Term Loan.

(i) Subject to and upon the terms and conditions of this Agreement, Bank agrees to make a Term Loan to Borrower in an aggregate principal amount not to exceed Fourteen Million Dollars ($14,000,000), consisting of Tranche I and Tranche II, as follows: (i) Tranche I shall be available on the Closing Date with at least $3,000,000 funded on the Closing Date, provided Borrower may elect not to fund any portion of Term Loan in exchange for a fee of $25,000, and (ii) Tranche II shall be available upon Borrower meeting the Performance Milestone. The proceeds of the Term Loan shall be used for general working capital purposes.

(ii) Interest shall accrue from the date of the Term Loan at the rate specified in Section 2.2(a), and shall be payable monthly beginning on the first day of the

1.

month next following the Term Loan, and continuing on the same day of each month thereafter. If the Amortization Date is the first anniversary of the Closing Date, then Borrower will repay the outstanding principal balance of the Term Loan as of the Amortization Date in thirty six (36) equal monthly installments of principal plus accrued interest. If the Amortization Date has been extended to November 29, 2021, then Borrower will repay the outstanding principal balance of the Term Loan as of the Amortization Date in thirty (30) equal monthly payments of principal plus accrued interest. In both cases, payments shall be due on the first day of each month. On the Maturity Date all amounts due in connection with the Term Loan and any other amounts due under this Agreement shall be immediately due and payable. Term Loan, once repaid, may not be reborrowed. Borrower may prepay the Term Loan at any time without penalty or premium.

(iii) When Borrower desires to obtain a Term Loan, Borrower shall notify Bank (which notice shall be irrevocable) by email to be received no later than 3:30 p.m. Eastern time on the day on which the Term Loan is to be made. Such notice shall be given by a Loan Advance/Paydown Request Form in substantially the form of Exhibit C. The notice shall be signed by an Authorized Officer. Bank shall be entitled to rely on any notice given by a person whom Bank reasonably believes to be an Authorized Officer, and Borrower shall indemnify and hold Bank harmless for any damages, loss, costs and expenses suffered by Bank as a result of such reliance, except for losses caused by Bank’s gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and non-appealable order.

2.2 Interest Rates, Payments, and Calculations.

(a) Interest Rates.

(i) Term Loans. Except as set forth in Section 2.2(b), the Term Loans shall bear interest, on the outstanding daily balance thereof, at a floating annual rate equal to the greater of: (A) 1.75% above the Prime Rate then in effect; or (B) 5.00%.

(b) Late Fee; Default Rate. If any payment is not made within 15 days after the date such payment is due, Borrower shall pay Bank a late fee equal to the lesser of (i) 5% of the amount of such unpaid amount or (ii) the maximum amount permitted to be charged under applicable law. After the occurrence and during the continuance of an Event of Default, all Obligations shall bear interest, upon notice of such increase given by Bank, at a rate equal to five (5) percentage points above the interest rate applicable immediately prior to the occurrence of the Event of Default (such rate, the “Default Rate”); provided, that, from and after the occurrence of any Event of Default described in Section 8.5, such increase shall be automatic and without the requirement of any notice from Bank. In all such events, and notwithstanding the date on which application of the Default Rate is communicated to Borrower, the Default Rate may be accrued (at the election of Bank) from the initial date of any Event of Default until all existing Events of Default are waived in writing in accordance with the terms of this Agreement.

(c) Payments. Borrower authorizes Bank to, at its option, charge such interest, all Bank Expenses, all Periodic Payments, and any other amounts due and owing in accordance with the terms of this Agreement against any of Borrower’s deposit accounts, held with Bank, and to extent there is not sufficient funds in such deposit accounts, such charged amounts shall thereafter accrue interest at the rate then applicable hereunder. Any interest not paid when due or charged pursuant to the foregoing sentence shall be compounded by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder.

2.

(d) Computation. In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such change in the Prime Rate. All interest chargeable under the Loan Documents shall be computed on the basis of a 360 day year for the actual number of days elapsed.

2.3 Crediting Payments. Prior to the occurrence of an Event of Default, Bank shall credit a wire transfer of funds, check or other item of payment to such deposit account or Obligation as Borrower specifies. After the occurrence and during the continuance of an Event of Default, Bank shall have the right, in its sole discretion, to immediately apply any wire transfer of funds, check, or other item of payment Bank may receive to conditionally reduce Obligations, but such applications of funds shall not be considered a payment on account unless such payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank after 3:30 p.m. Eastern time shall be deemed to have been received by Bank as of the opening of business on the immediately following Business Day. Whenever any payment to Bank under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension.

2.4 Fees. Borrower shall pay to Bank the following:

(a) Facility Fee. Waived;

(b) Bank Expenses. On the Closing Date, all Bank Expenses incurred through the Closing Date, and, after the Closing Date, all Bank Expenses, as and when they become due.

This Section 2.4(c) shall survive ten (10) years from the date of Payment in Full. If this Agreement is terminated prior to payment of the Success Fee, Borrower shall, give Bank written notice of the first Success Fee Event to occur thereafter, and pay the Success Fee upon the closing of such Success Fee Event.

2.5 Term. This Agreement shall become effective on the Closing Date and, subject to Section 12.7, shall continue in full force and effect until Payment in Full. Notwithstanding the foregoing, Bank shall have the right to terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance of an Event of Default.

The making of each Credit Extension shall be deemed to be a representation and warranty by Borrower on the date of such Credit Extension as to the accuracy of the facts referred to in this Section 3.2.

4. CREATION OF SECURITY INTEREST.

4.1 Grant of Security Interest. Borrower grants and pledges to Bank a continuing security interest in the Collateral to secure prompt repayment of any and all Obligations and to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents. Except for Permitted Liens or as disclosed in the Schedule and Collateral located outside of the United States, such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and will constitute a valid, first priority security interest in later-acquired Collateral. Notwithstanding any termination of this Agreement or of any filings undertaken related to Bank’s rights under the Code, Bank’s Lien on the Collateral shall remain in effect until such Lien is released pursuant to the term hereof or Payment in Full.

4.2 Perfection of Security Interest. Borrower authorizes Bank to file at any time financing statements, continuation statements, and amendments thereto that (i) either specifically describe the Collateral or describe the Collateral as all assets of Borrower of the kind pledged hereunder, and (ii) contain any other information required by the Code for the sufficiency of filing office acceptance of any financing statement, continuation statement, or amendment, including whether Borrower is an organization, the type of organization and any organizational identification number issued to Borrower, if applicable. Borrower shall have possession of the Collateral, except where expressly otherwise provided in this Agreement or where Bank chooses to perfect its security interest by possession in addition to the filing of a financing statement. Where Collateral is in possession of a third party bailee, Borrower shall take such steps as Bank reasonably requests for Bank to (i) subject to Section 7.10 below, obtain an acknowledgment, in form and substance reasonably satisfactory to Bank, of the bailee that the bailee holds such Collateral for the benefit of Bank, and (ii) obtain “control” of any Collateral consisting of investment property, deposit accounts (other than Permitted Outside Accounts), letter-of-credit rights or electronic chattel paper (as such items and the term “control” are defined in Revised Article 9 of the Code) by causing the securities intermediary or depositary institution or issuing bank to execute a control agreement in form and substance reasonably satisfactory to Bank. Borrower will not create any chattel paper with a book value in excess of $250,000 without placing a legend on the chattel paper reasonably acceptable to Bank indicating that Bank has a security interest in the chattel paper. Borrower from time to time may deposit with Bank specific cash collateral to secure specific Obligations; Borrower authorizes Bank to hold such specific balances

5.

in pledge and to decline to honor any drafts thereon or any request by Borrower or any other Person to pay or otherwise transfer any part of such balances until Payment in Full. Borrower shall take such other actions as Bank reasonably requests to perfect its security interests granted under this Agreement.

5. REPRESENTATIONS AND WARRANTIES.

Borrower represents and warrants as follows:

5.1 Due Organization and Qualification. Borrower and each Subsidiary is duly existing under the laws of the state in which it is organized and qualified and licensed to do business in any state in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect.

5.2 Due Authorization; No Conflict. The execution, delivery, and performance of the Loan Documents are within Borrower’s powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in Borrower’s Certificate of Incorporation or Bylaws, nor will they constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement by which it is bound, except to the extent such default would not reasonably be expected to cause a Material Adverse Effect.

5.3 Collateral. Borrower has rights in or the power to transfer the Collateral, and its title to the Collateral is free and clear of Liens, adverse claims, and restrictions on transfer or pledge except for Permitted Liens. As of the Closing Date, except as set forth in the Schedule, all Collateral is located solely in the United States. All Inventory is in all material respects of good and merchantable quality, free from all material defects, except for Inventory for which adequate reserves have been made. As of the Closing Date, except as set forth in the Schedule, none of the Borrower’s Cash is maintained or invested with a Person other than Bank or Bank’s affiliates as of the Closing Date.

5.4 Intellectual Property. Borrower is the sole owner of the intellectual property created or purchased by Borrower, except for in-licenses not prohibited by this Agreement and licenses granted by Borrower in the ordinary course of business or otherwise constituting an arms-length transaction, the terms of which, on its face, do not provide for a sale or assignment by Borrower of any intellectual property (collectively, “Permitted Licenses”). To the best of Borrower’s knowledge, the intellectual property created or purchased by Borrower constitutes all intellectual property necessary for the conduct of Borrower’s business as now conducted and as presently proposed to be conducted, except to the extent the failure to create or purchase such intellectual property would not reasonably be expected to cause a Material Adverse Effect. To the best of Borrower’s knowledge, each of the copyrights, trademarks and patents created or purchased by Borrower is valid and enforceable, and no part of the intellectual property created or purchased by Borrower has been judged invalid or unenforceable, in whole or in part, and no claim has been made to Borrower that any part of the intellectual property created or purchased by Borrower violates the rights of any third party except to the extent such claim would not reasonably be expected to cause a Material Adverse Effect.

6.

5.5 Name; Location of Chief Executive Office. Except as disclosed in the Schedule, Borrower has not done business in the last five years under any name other than that specified on the signature page hereof, and its exact legal name is as set forth in the first paragraph of this Agreement. The chief executive office of Borrower is located at the address indicated in Section 10 hereof.

5.6 Litigation. Except as set forth in the Schedule, there are no actions or proceedings pending by or against Borrower or any Subsidiary before any court or administrative agency in which a likely adverse decision would reasonably be expected to have a Material Adverse Effect.

5.9 Compliance with Laws and Regulations. Borrower and each Subsidiary have met the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from Borrower’s failure to comply with ERISA that is reasonably likely to result in Borrower’s incurring any liability that could have a Material Adverse Effect. Borrower is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940. Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations T and U of the Board of Governors of the Federal Reserve System).

Borrower and each Subsidiary have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s business as currently conducted, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect.

7.

5.12 Restrictions on Granting Liens. Except as disclosed on the Schedule and agreements constituting Excluded Collateral, Permitted Licenses or inbound license agreements to the extent Section 6.8 hereof is complied with, Borrower is not a party to, nor is bound by, any material license or other material agreement necessary for the conduct of Borrower’s business that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement, other than this Agreement or the other Loan Documents.

5.13 Full Disclosure. No representation, warranty or other statement made by Borrower in any certificate or written statement furnished to Bank (other than financial or business projections, forecasts or other information of a forward-looking nature) taken together with all such certificates and written statements furnished to Bank contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained in such certificates or statements not misleading in light of the circumstances in which they were made at the time such statement was made or deemed made. The projections, forecasts and other information of a forward-looking nature have been provided by Borrower in good faith and based upon reasonable assumptions, it being understood and agreed by Bank that such information is not to be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may differ from the projected or forecasted results.

Borrower shall meet, and shall cause each Subsidiary to meet, the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. Borrower shall comply, and shall cause each Subsidiary to comply, with all statutes, laws, ordinances and government rules and regulations to which it is subject to the extent non-compliance therewith would reasonably be expected to have a Material Adverse Effect, and shall maintain, and shall cause each of its Subsidiaries to maintain, in force all licenses, approvals and agreements, the loss of which or failure to comply with which would reasonably be expected to have a Material Adverse Effect.

6.5 Insurance. Borrower, at its expense, shall (i) keep the Collateral insured against loss or damage, and (ii) maintain liability and other insurance, in each case as ordinarily insured against by other owners in businesses similar to Borrower’s.

6.9 Creation/Acquisition of Subsidiaries. In the event Borrower or any Subsidiary of Borrower creates or acquires any Subsidiary, Borrower or such Subsidiary shall promptly (and in any event on or prior to the next Reporting Date) notify Bank of such creation or acquisition, and Borrower or such Subsidiary shall take all actions reasonably requested by Bank to achieve any of the following with respect to such “New Subsidiary” (defined as a Subsidiary formed after the date hereof during the term of this Agreement): (i) to cause such New Subsidiary to become either (A) a co-borrower hereunder, if such New Subsidiary is organized under the laws of the United States, or (B) a secured guarantor with respect to the Obligations, if such New Subsidiary is not organized under the laws of the United States; and (ii) to grant and pledge to Bank a perfected security interest in (x) all of the stock, units or other evidence of ownership held by Borrower or its Subsidiaries of any such New Subsidiary organized under the laws of the United States and (y) all of the stock, units or other evidence of ownership held by Borrower or its Subsidiaries of any such New Subsidiary organized under the laws of a jurisdiction outside of the United States (other than property that constitutes the capital stock of a controlled foreign corporation (as defined in the IRC), in excess of 65% of the voting power of all classes of capital stock of such controlled foreign corporations entitled to vote, if the grant of a security interest in such capital stock pursuant to this Agreement would result in material adverse “deemed dividend” tax consequences to Borrower due to the application of IRC §956) that constitutes Collateral hereunder.

6.10 Existing Letter of Credit. Borrower shall be permitted to maintain Borrower’s existing cash collateral accounts at Boston Private Bank (the “BPB Collateral Account”) securing that certain letter of credit for $206,441 in favor of VTR LS 1030 Mass Ave, LLC (the “Letter of Credit”), provided further that the aggregate balance of the BPB Collateral Account shall not exceed $206,441 at any time and upon the earlier of (x) the maturity date of such Letter of Credit as of the Closing Date which is March 26, 2021 and (y) such earlier maturity or termination of such Letter of Credit, the entire balance held in the applicable BPB Collateral Account shall immediately be transferred to one of Borrower’s accounts at Bank.

14.

such default within 10 days after Borrower receives notice thereof or any officer of Borrower becomes aware thereof; provided, however, that if the default cannot by its nature be cured within the 10 day period or cannot after diligent attempts by Borrower be cured within such 10 day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional reasonable period (which shall not in any case exceed 30 days) to attempt to cure such default, and within such reasonable time period the failure to have cured such default shall not be deemed an Event of Default but no Credit Extensions will be made;

8.4 Attachment. If any material portion of Borrower’s assets is attached, seized, subjected to a writ or distress warrant, or is levied upon, or comes into the possession of any trustee, receiver or person acting in a similar capacity and such attachment, seizure, writ or distress warrant or levy has not been removed, discharged or rescinded within 10 days, or if Borrower is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs, or if a judgment or other claim becomes a lien or encumbrance upon any material portion of Borrower’s assets, or if a notice of lien, levy, or assessment is filed of record with respect to any material portion of Borrower’s assets by the United States Government, or any department, agency, or instrumentality thereof, or by any state, county, municipal, or governmental agency, and the same is not paid within ten days after Borrower receives notice thereof, provided that none of the foregoing shall constitute an Event of Default where such action or event is stayed or an adequate bond has been posted pending a good faith contest by Borrower (provided that no Credit Extensions will be made during such cure period);

8.5 Insolvency. If Borrower becomes insolvent, or if an Insolvency Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced against Borrower and is not dismissed or stayed within 45 days (provided that no Credit Extensions will be made prior to the dismissal of such Insolvency Proceeding);

9. BANK’S RIGHTS AND REMEDIES.

9.1 Rights and Remedies. Upon the occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower:

(a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that upon the occurrence of an Event of Default described in Section 8.5 (insolvency), all Obligations shall become immediately due and payable without any action by Bank);

(b) Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement between Borrower and Bank;

(c) Settle or adjust disputes and claims directly with account debtors for amounts, upon terms and in whatever order that Bank reasonably considers advisable;

(d) Make such payments and do such acts as Bank considers necessary or reasonable to protect its security interest in the Collateral. Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate. Borrower authorizes Bank to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s determination appears to be prior or superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants Bank a license to enter into possession of such premises and to occupy the same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise;

(e) place a “hold” on any account maintained with Bank, decline to honor presentments (including but not limited to checks, wires, and ACH drafts) against any account at Bank, and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any control agreement or similar agreements providing control of any Collateral;

(f) Set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by Bank, and (ii) indebtedness at any time owing to or for the credit or the account of Borrower held by Bank;

(g) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Bank is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade

16.

names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit;

(h) Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Bank determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. If Bank sells any of the Collateral upon credit, Borrower will be credited only with payments actually made by the purchaser, received by Bank, and applied to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank may resell the Collateral and Borrower shall be credited with the proceeds of the sale;

(i) Bank may credit bid and purchase at any public sale;

(j) Apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without notice and without regard to the adequacy of the security for the Obligations and without regard to the solvency of Borrower, any Guarantor or any other Person liable for any of the Obligations; and

(k) Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower.

Bank may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby irrevocably appoints Bank (and any of Bank’s designated officers, or employees) as Borrower’s true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign Borrower’s name on any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to Borrower’s policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; and (g) file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral; provided Bank may exercise such power of attorney to sign the name of Borrower on any of the documents described in clause (g) above, regardless of whether an Event of Default has occurred. The appointment of Bank as Borrower’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until Payment in Full.

17.

9.3 Accounts Collection. At any time after the occurrence and during the continuation of an Event of Default, Bank may notify any Person owing funds to Borrower of Bank’s security interest in such funds and verify the amount of such Account. Borrower shall collect all amounts owing to Borrower for Bank, receive in trust all payments as Bank’s trustee, and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to Borrower: (a) make payment of the same or any part thereof; and/or (b) obtain and maintain insurance policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default under this Agreement.

9.5 Bank’s Liability for Collateral. Bank has no obligation to clean up or otherwise prepare the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower.

9.6 No Obligation to Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by collecting them from any other person liable for them and Bank may release, modify or waive any collateral provided by any other Person to secure any of the Obligations, all without affecting Bank’s rights against Borrower. Borrower waives any right it may have to require Bank to pursue any other Person for any of the Obligations.

9.7 Remedies Cumulative. Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. Borrower expressly agrees that this Section 9.7 may not be waived or modified by Bank by course of performance, conduct, estoppel or otherwise.

9.8 Demand; Protest. Except as otherwise provided in this Agreement, Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment and any other notices relating to the Obligations.

10. NOTICES.

Unless otherwise provided in this Agreement, all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in writing

18.

THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY BANK OR BORROWER, EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM. If the jury waiver set forth in this Section 11 is not enforceable, then any dispute, controversy, claim, action or similar proceeding arising out of or relating to this Agreement, the Loan Documents or any of the transactions contemplated therein shall be settled by final and binding arbitration held in Durham County, North Carolina in accordance with the then current Commercial Arbitration Rules of the American Arbitration Association by one arbitrator appointed in accordance with those rules. The arbitrator shall apply North Carolina law to the resolution of any dispute, without reference to rules of conflicts of law or rules of statutory arbitration. Judgment upon any award resulting from arbitration may be entered into and enforced by any state or federal court having jurisdiction thereof. Notwithstanding the foregoing, the parties may apply to any court of competent jurisdiction for preliminary or interim equitable relief, or to compel arbitration in accordance with this Section. The costs and expenses of the arbitration, including without limitation, the arbitrator’s fees and expert witness fees, and reasonable attorneys’ fees, incurred by the parties to the arbitration may be awarded to the prevailing party, in the discretion of the arbitrator, or may be apportioned between the parties in any manner deemed appropriate by the arbitrator. Unless and until the arbitrator decides that one party is to pay for all (or a share) of such costs and expenses, both parties shall share equally in the payment of the arbitrator’s fees as and when billed by the arbitrator.

12. GENERAL PROVISIONS.
