Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein. All references to “Dollars” or “$” are United States Dollars, unless otherwise noted.


2.	LOANS AND TERMS OF PAYMENT

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay the Lender the outstanding principal amount of all Term Loans advanced to Borrower by the Lender and accrued and unpaid interest thereon and any other amounts due hereunder as and when due in accordance with this Agreement.

2.2 Term Loans.

(a) Availability. Subject to the terms and conditions of this Agreement, the Lender agrees to make one or more term loans to Borrower during the period beginning on the Effective Date and ending on the Maturity Date in an aggregate amount not to exceed Thirty Million Dollars ($30,000,000.00) (such term loans are hereinafter referred to singly as a “Term

Loan”, and collectively as the “Term Loans”). Each Term Loan shall be in an aggregate minimum amount of $3,000,000 and integral multiples of $500,000 in excess of that amount. After repayment, no Term Loan may be re-borrowed.

(b) Repayment. All principal and accrued and unpaid interest with respect to each Term Loan that has not been converted to Conversion Stock or exchanged for an Exchange Note is due and payable in full on the Maturity Date. The Term Loans may only be prepaid in accordance with Section 2.2(c) and 2.2(d).

(c) Mandatory Prepayments. If the Term Loans are accelerated following the occurrence of an Event of Default, Borrower shall immediately pay to the Lender an amount equal to the sum of: (i) all outstanding principal of the Term Loans plus accrued and unpaid interest thereon through the prepayment date, plus (ii) all other Obligations that are due and payable, including Lender Expenses and interest at the Default Rate with respect to any past due amounts.

(d) Permitted Prepayment of Term Loans. Subject to Lender’s conversion rights pursuant to Section 2.7(d), Borrower shall have the option to prepay all of the Term Loans, at any time, provided Borrower (i) provides written notice (the “Prepayment Notice”) to the Lender of its election to prepay the Term Loans at least fifteen (15) days prior to such prepayment (or such shorter period of time as acceptable to the Lender in its reasonable discretion), and (ii) pays to the Lender on the date of such prepayment an amount equal to the sum of (A) all outstanding principal of the Term Loans plus all accrued and unpaid interest thereon through the prepayment date, plus (B) all other Obligations that are due and payable, including interest at the Default Rate with respect to any past due amounts.

2.3 Payment of Interest on the Credit Extensions.

Subject to Section 2.3(b), the principal amount outstanding under the Term Loans drawn prior to June 30, 2018 (the “Initial Term Loans”) shall accrue no interest from the date of such Term Loan through and including June 30, 2018. Beginning on July 1, 2018, all Initial Term Loans, and all Term Loans drawn on or after July 1, 2018, shall accrue interest at a fixed per annum rate (which rate shall be fixed for the duration of the applicable Term Loan) equal to the Basic Rate. Interest shall accrue on each Term Loan commencing on, and including, the later of July 1, 2018 and the Funding Date of such Term Loan, and shall accrue on the principal amount outstanding under such Term Loan through and including the day on which such Term Loan is converted to Conversion Stock, exchanged for an Exchange Note, or paid in full.

(b) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall accrue interest at a fixed per annum rate equal to the rate that is otherwise applicable thereto plus five percentage points (5.00%) (the “Default Rate”). Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of the Lender.

(c) 360-Day Year. Interest shall be computed on the basis of a three hundred sixty (360) day year consisting of twelve (12) months of thirty (30) days, and shall be compounded annually.

Except as otherwise expressly provided herein, all payments by Borrower under the Loan Documents shall be made to the Lender at its office in immediately available funds on the date specified herein. Payments of principal and/or interest received after 2:00 p.m. Eastern 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 is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue until paid. All payments to be made by Borrower hereunder or under any other Loan Document, including payments of principal and interest, and all fees, expenses, indemnities and reimbursements, shall be made without set-off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds.

2.4 Secured Convertible Promissory Notes.

(a) Form of Note. Each Term Loan shall be evidenced by a separate Secured Convertible Promissory Note in the form attached as Exhibit C hereto (each a “Secured Promissory Note”), and shall be repayable, convertible and exchangeable as set forth in this Agreement and such Secured Promissory Note.

(b) Replacement Notes. Upon receipt of an affidavit of an officer of the Lender as to the loss, theft, destruction, or mutilation of any Secured Promissory Note, Borrower shall issue, in lieu thereof, a replacement Secured Promissory Note in the same principal amount thereof and of like tenor.

2.5 Expenses. Borrower and the Lender shall each pay all costs and expenses (including attorneys’ fees) that it incurs with respect to preparing and negotiating and, except in connection with defending or enforcing the Loan Documents, amending and administering the Loan Documents incurred through and after the Effective Date. Borrower shall pay to the Lender all Lender Expenses that it incurs with respect to defending and enforcing the Loan Documents (including, without limitation, those incurred in connection with (a) appeals or Insolvency Proceedings and (b) amending and administering the Loan Documents in connection with defending and enforcing the Loan Documents) incurred through and after the Effective Date, when due.

2.6 Withholding. Payments received by the Lender from Borrower hereunder 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 the 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, the 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 the Lender with proof reasonably satisfactory to the 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 2.6 shall survive the termination of this Agreement. The Lender shall deliver to Borrower, on or prior to the date on which such the Lender becomes a party to this Agreement (and from time to time thereafter upon the reasonable request of Borrower), a properly completed and duly executed original of IRS Form W-9 or any successor form, certifying that the Lender is exempt from United States federal backup withholding tax.

The Lender’s exercise of its conversion rights under this section shall be deemed to satisfy its obligation to pay the principal amount of Term Loans, in respect of which such conversion right is being exercised as of the date of the applicable Conversion Date.

(e) Conversion/Exchange Procedures.

(i) If Borrower intends to consummate a Qualified Event (other than a Prepayment Conversion under Section 2.2(d)), Borrower shall deliver to the Lender written notice of all material terms (including the proposed date of consummation) of, and then current documentation with respect to, such Qualified Event as soon as reasonably practicable and, in any event, at least fifteen (15) days prior to the proposed date of consummation of such Qualified Event.

If the Lender desires to convert or exchange one or more Secured Promissory Note(s) pursuant to Section 2.7(d), in connection with a Prepayment Conversion, Lender shall deliver written notice to Borrower at least three (3) Business Days prior to the proposed date of consummation of such Prepayment Conversion.

(ii) On the Conversion Date, (A) the holder of a Secured Promissory Note to be converted or exchanged in such Qualified Event will surrender such Secured Promissory Note(s), duly endorsed, to Borrower in the manner and at the place reasonably designated by Borrower and (B) Borrower will issue to such holder the Conversion Stock or Exchange Note, as applicable. Borrower shall be deemed to have fully and indefeasibly performed all of its obligations under each Secured Promissory Note so converted or exchanged, and each holder of each Secured Promissory Note so converted or exchanged shall immediately upon such conversion or exchange be, for all purposes, the record holder of such Conversion Stock or Exchange Note, as applicable.

(iii) If, within six (6) months following a Prepayment Conversion (the “Lookback Period”), the Company consummates a Qualified Equity Financing (a “Post Conversion Equity Financing”), Lender may, at its option exchange the Conversion Stock issued to Lender in connection with the Prepayment Conversion for the preferred stock issued in such Post Conversion Equity Financing (such right, the “Equity Exchange Right”); provided, however, that each of Lender’s Equity Exchange Right shall immediately terminate and the Lookback Period shall be reduced to zero (0) days immediately following (a) the occurrence of any Change of Control and/or Liquidation, and (b) the occurrence of any Post Conversion Equity Financing. If Borrower

intends to consummate a Post Conversion Equity Financing, Borrower shall deliver to the Lender written notice of all material terms (including the proposed date of consummation) of, and documentation with respect to, such Post Conversion Equity Financing as soon as reasonably practicable and, in any event, at least fifteen (15) days prior to the proposed date of consummation of such Post Conversion Equity Financing. If the Lender desires to exercise its Equity Exchange Right, Lender shall deliver written notice (the “Exchange Notice”) to Borrower at least three (3) Business Days prior to the initial date of termination for the Lookback Period. If Lender provides the Exchange Notice, effective on the consummation of the Post Conversion Equity Financing, (a) each share of Conversion Stock issued to Lender and/or its affiliates, successors and assigns in connection with the Prepayment Conversion shall be automatically exchanged for the preferred stock issued in such Post Conversion Equity Financing at a ratio obtained by dividing the Conversion Stock Per Share Price in the Prepayment Conversion by the lowest price per share of preferred stock paid by any investor in such Post Conversion Equity Financing, and (b) each of Lender’s Lookback Exchange Rights shall immediately terminate and the Lookback Period shall be reduced to zero (0) days.

(iv) If, within the Lookback Period, Borrower consummates a Change in Control or Liquidation (a “Post Conversion Change in Control”), Lender may, at its option, exchange the Conversion Stock issued to Lender in connection with the Prepayment Conversion for the Conversion Stock that Lender would have received had the Secured Promissory Note(s) that were converted in the Prepayment Conversion been converted pursuant to Section 2.7(b) instead (such right, the “Change in Control Exchange Right”); provided, however, that each of Lender’s Lookback Exchange Rights shall immediately terminate and the Lookback Period shall be reduced to zero (0) days immediately following the occurrence of such Change of Control and/or Liquidation. If Lender desires to exercise its Change in Control Exchange Right, (a) Borrower and Lender shall follow the Conversion/Exchange Procedures set forth in Section 2.7(e)(i), (b) effective immediately prior to the closing of the Post Conversion Change in Control, all Conversion Stock issued to Lender and/or its affiliates, successors and assigns in connection with the Prepayment Conversion shall be automatically exchanged for the number of shares of Conversion Stock that Lender would have received had the Secured Promissory Note(s) that were converted in the Prepayment Conversion been converted pursuant to Section 2.7(b) instead, and (c) each of Lender’s Lookback Exchange Rights shall immediately terminate.

(v) Borrower shall not issue fractional shares upon conversion of any Secured Promissory Note or exchange of Conversion Stock. In lieu of issuing fractional shares, Borrower will pay to the holder of a Secured Promissory Note converted in a Qualified Event a cash amount equal the amount designated for conversion but not so converted. In lieu of issuing fractional shares in a Post Conversion Equity Financing, Lender will retain – and not exchange – a number of shares of Conversion Stock such that only a whole number of shares of preferred stock are issued to Lender in any Post Conversion Equity Financing.

(f) Reservation of Shares. Borrower will take all such actions reasonably necessary to authorize a sufficient number of shares of preferred stock or other applicable capital stock, as applicable, to allow for the conversion of the maximum amount of Secured Promissory Notes or exchange of Conversion Stock issuable hereunder into preferred stock or other capital stock, as applicable prior to the conversion of such Secured Promissory Notes or exchange of

Conversion Stock; provided, however, that nothing herein will be deemed to require Borrower to authorize the issuance of preferred stock solely for purposes of converting Secured Promissory Notes unless Borrower is authorizing and issuing preferred stock in connection with a Qualified Equity Financing or Post Conversion Equity Financing or delivering a Prepayment Notice.

(g) Investors Rights. The conversion or exchange of any Secured Promissory Note pursuant to this Section 7.7 is subject to Borrower providing Lender such rights, benefits and preferences (including representations and warranties, rights of first refusal, registration rights, warrant coverage and legal opinion) as generally enjoyed by all investors in the Qualified Equity Financing or Post Conversion Equity Financing, including pursuant to the Stockholder Documents and Lender executing all financing documents executed by other investors in the Qualified Equity Financing or Post Conversion Equity Financing.

Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties in Section 5 hereof are true, accurate and complete in all material respects; provided, however, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date shall be true, accurate and complete in all material respects as of such date;

3.3 Covenant to Deliver. Borrower agrees to deliver to the Lender each item required to be delivered to the 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 the Lender of any such item shall not constitute a waiver by the Lender of Borrower’s obligation to deliver such item, and any such Credit Extension in the absence of a required item shall be made in the Lender’s sole discretion.

3.4 Procedures for Borrowing. Subject to the prior satisfaction of all other applicable conditions to the making of a Term Loan set forth in this Agreement, to obtain a Term Loan, Borrower shall deliver a Borrowing Request executed by a Responsible Officer or his or her designee to the Lender (which Borrowing Request shall be irrevocable) by electronic mail, facsimile, or telephone by 2:00 p.m. Eastern time five (5) Business Days prior to the date the Term Loan is to be made. On the Funding Date, the Lender shall transfer an amount equal to such Term Loan pursuant to the Borrowing Request.

4.CREATION OF SECURITY INTEREST

4.1 Grant of Security Interest. Borrower hereby grants the Lender, to secure the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to the Lender, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrower represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected

security interest in the Collateral, subject only to Permitted Liens that are permitted by the terms of this Agreement to have priority to the Lender’s Lien. If Borrower shall acquire a commercial tort claim (as defined in the Code), Borrower shall promptly notify the Lender in a writing signed by Borrower of the general details thereof (and further details as may be reasonably required by the Lender) and grant to the 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 the Lender.

If this Agreement is terminated, the Lender’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) are repaid in full. Upon payment in full of the Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) and at such time as the Lender’s obligation to make Credit Extensions has terminated, the Lender shall, at the sole cost and expense of Borrower, release its Liens in the Collateral and all rights therein shall revert to Borrower.

Upon any sale, lease, transfer or other disposition of any item of Collateral of any Borrower or Guarantor not prohibited by the terms of the Loan Documents, or upon the effectiveness of any consent to the release of the security interest granted hereby in any Collateral pursuant to this Agreement, or upon the release of any Borrower or any Guarantor from its obligations under this Agreement or the applicable Guaranty, if any, in accordance with the terms of the Loan Documents, the Lender will, at such Borrower’s or Guarantor’s sole cost and expense, execute and deliver to such Borrower or Guarantor such documents as such Borrower or Guarantor shall reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted hereby; provided, however, that (i) at the time of such request and such release no Event of Default shall have occurred and be continuing and (ii) such Borrower or Guarantor shall have delivered to the Lender, at least ten (10) Business Days’ prior to the date of the proposed release, a written request for release describing the item of Collateral, together with a form of release for execution by the Lender, and such other information as the Lender may reasonably request.

4.2 Authorization to File Financing Statements. Borrower hereby authorizes the Lender to file financing statements or take any other action required to perfect the Lender’s security interests in the Collateral, without notice to Borrower, with all appropriate jurisdictions to perfect or protect the Lender’s interest or rights under the Loan Documents, including a notice that any disposition of the Collateral, except to the extent permitted by the terms of this Agreement, by Borrower, or any other Person, shall be deemed to violate the rights of the Lender under the Code. Such financing statements may indicate the Collateral as “all assets of the Debtor’s” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all as reasonably determined by the Lender.

4.3 Pledge of Share Collateral. Borrower hereby pledges, assigns and grants to the Lender a security interest in all the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or granted in connection therewith, and all other cash and noncash proceeds of the foregoing, as security for the performance of the Obligations. To the extent required by the terms and conditions governing the Shares, Borrower shall cause the books of each entity whose Shares are part of the

Collateral and any transfer agent to reflect the pledge of the Shares. Upon the occurrence and during the continuance of an Event of Default hereunder and subject to the terms of the Subordination Agreement, the Lender may effect the transfer of any securities included in the Collateral (including but not limited to the Shares) into the name of the Lender and cause new (as applicable) certificates representing such securities to be issued in the name of the Lender or its transferee. Subject to the terms of the Subordination Agreement Borrower will execute and deliver such documents, and take or cause to be taken such actions, as the Lender may reasonably request to perfect or continue the perfection of the Lender’s security interest in the Shares. Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any voting rights with respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.

5.REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants to the Lender as follows:

The Borrower is a Registered Organization. In connection with this Agreement, Borrower and each of its Subsidiaries has delivered to the Lender a completed perfection certificate signed by an officer of Borrower or such Subsidiary (each a “Perfection Certificate” and collectively, the “Perfection Certificates”). Borrower represents and warrants that (a) Borrower and each of its Subsidiaries’ exact legal name is that which is indicated on its respective Perfection Certificate and on the signature page of each Loan Document to which it is a party; (b) Borrower and each of its Subsidiaries is an organization of the type and is organized in the jurisdiction set forth on its respective Perfection Certificate; (c) each Perfection Certificate accurately sets forth each of Borrower’s and its Subsidiaries’ organizational identification number or accurately states that Borrower or such Subsidiary has none; (d) each Perfection Certificate accurately sets forth Borrower’s and each of its Subsidiaries’ place of business, or, if more than one, its chief executive office as well as Borrower’s and each of its Subsidiaries’ mailing address (if different than its chief executive office); (e) except as set forth in the Perfection Certificate, Borrower and each of its Subsidiaries (and each of its respective predecessors) have not, in the past five (5) years, changed its jurisdiction of organization, organizational structure or type, or any organizational number assigned by its jurisdiction; and (f) all other information set forth on the Perfection Certificates pertaining to Borrower and each of its Subsidiaries, is accurate and complete (it being understood and agreed that Borrower and each of its Subsidiaries may from time to time update certain information in the Perfection Certificates (including the information set forth in clause (d) above) after the Effective Date to the extent permitted by one or more specific provisions in this Agreement); such updated Perfection Certificates subject to the review and approval of the Lender. If Borrower or any of its Subsidiaries is not now a Registered Organization but later becomes one,

Borrower shall notify the Lender of such occurrence and provide the Lender with such Person’s organizational identification number within five (5) Business Days of receiving such organizational identification number.

(d) Borrower and each of its Subsidiaries is the sole owner of the Intellectual Property each respectively purports to own, free and clear of all Liens other than Permitted Liens. Each of Borrower’s and its Subsidiaries’ material Patents is valid and enforceable and no part of Borrower’s or its Subsidiaries’ material Intellectual Property has been judged invalid or unenforceable, in whole or in part, and (ii) to the best of Borrower’s knowledge, no claim has been made that any part of the Intellectual Property or any practice by Borrower or its Subsidiaries violates the rights of any third party except to the extent such claim could not reasonably be expected to have a Material Adverse Change. Except as noted on the Perfection Certificates, neither Borrower nor any of the Guarantors is a party to, nor is bound by, any material license or other material agreement with respect to which Borrower or such Guarantor is the licensee that (i) prohibits or otherwise restricts Borrower or the Guarantors from granting a security interest in Borrower’s or such Guarantor’s interest in such material license or material agreement or any other property, or

(ii) for which a default under or termination of could interfere with the Lender’s right to sell any Collateral. Borrower shall provide written notice to the Lender within ten (10) days of Borrower or any of its Subsidiaries entering into or becoming bound by any material license or agreement with respect to which Borrower or any Subsidiary is the licensee (other than over-the-counter software that is commercially available to the public).

5.3 Litigation. Except as disclosed (i) on the Perfection Certificates, or (ii) in accordance with Section 6.5 hereof, there are no actions, suits, investigations, or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or against Borrower or any of its Subsidiaries involving more than Two Hundred Fifty Thousand Dollars ($250,000.00).

Neither Borrower nor any of its Subsidiaries is 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 and each of its Subsidiaries have complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of 2005. Neither Borrower nor any of its Subsidiaries has violated any laws, ordinances or rules, the violation of which could reasonably be expected to have a Material Adverse Change. Neither Borrower’s nor any of its Subsidiaries’ properties or assets has been used by Borrower or such Subsidiary or, to Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than in material compliance with applicable laws. Borrower and each of its Subsidiaries has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all Governmental Authorities that are necessary to continue their respective businesses as currently conducted.

None of Borrower, any of its Subsidiaries, or any of Borrower’s or its Subsidiaries’ Affiliates or any of their respective agents acting or benefiting in any capacity in connection with the transactions contemplated by this Agreement is (i) in violation of any Anti-Terrorism Law, (ii) engaging in or conspiring to engage in any transaction that evades or avoids, or has the purpose of evading or avoiding or attempts to violate, any of the prohibitions set forth in any Anti-Terrorism Law, or (iii) a Blocked Person.

Borrower has full power and authority to create a lien on the Shares and no disability or contractual obligation exists that would prohibit Borrower from pledging the Shares pursuant to this Agreement. To Borrower’s knowledge, there are no subscriptions, warrants, rights of first refusal or other restrictions on transfer relative to, or options exercisable with respect to the Shares. The Shares have been and will be duly authorized and validly issued, and are fully paid and non-assessable (to the extent such concepts exist under applicable law). To Borrower’s knowledge, the Shares are not the subject of any present or threatened suit, action, arbitration, administrative or other proceeding, and Borrower knows of no reasonable grounds for the institution of any such proceedings.

5.9 Full Disclosure. No written representation, warranty or other statement of Borrower or any of its Subsidiaries in any certificate or written statement given to the Lender, as of the date such representation, warranty, or other statement was made, taken together with all such written certificates and written statements given to the Lender, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading in light of the circumstances under which such statements were made (after giving effect to all supplements and updates thereto) (it being recognized that the projections and forecasts provided by Borrower in good faith and based upon assumptions believed to be reasonable by the Borrower or such Subsidiary are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results).

5.10 Definition of “Knowledge.” For purposes of the Loan Documents, whenever a representation or warranty is made to Borrower’s knowledge or awareness, to the “best of” Borrower’s knowledge, or with a similar qualification, knowledge or awareness means the actual knowledge, after reasonable investigation, of the Responsible Officers.

Insurance policies shall be in a form, with companies, and in amounts that are reasonably satisfactory to the Lender. All property policies of Borrower or any Guarantor shall have a lender’s loss payable endorsement showing the Lender as lender loss payee and waive subrogation against the Lender, and all liability policies of the Borrower or any Guarantor shall show, or have endorsements showing, the Lender, as additional insured. The 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, and each provider of any such insurance shall agree, by endorsement upon the policy or policies issued by it or by independent instruments furnished to the Lender, that it will give the Lender thirty (30) days prior written notice before any such policy or policies shall be materially altered or canceled. At the Lender’s reasonable request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Subject to the terms of the Subordination Agreement, proceeds payable under any policy of the Borrower or any Guarantor or covering the Collateral shall, at the Lender’s option, be payable to the 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 up to One Hundred Thousand Dollars ($100,000.00) with respect to any loss, but not exceeding Two Hundred Fifty Thousand Dollars ($250,000.00), in the aggregate for all losses under all casualty or property policies in any fiscal year, 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 the Lender has been granted a security interest, 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 the Lender, be payable to the Lender on account of the Obligations. If Borrower or any of its Subsidiaries fails to obtain insurance as required under this Section 6.3 or to pay any amount or furnish any required proof of payment to third persons, the Lender may make, at Borrower’s expense, all or part of such payment or obtain such insurance policies required in this Section 6.3, and take any action under the policies the Lender deems prudent.

6.5 Notices of Litigation and Default. Borrower will give prompt written notice to the Lender of any litigation or governmental proceedings pending or threatened (in writing) against Borrower or any of its Subsidiaries, which could reasonably be expected to result in damages or costs to Borrower or any of its Subsidiaries of One Hundred Thousand Dollars ($100,000.00) or more or which could reasonably be expected to have a Material Adverse Change. Without limiting or contradicting any other more specific provision of this Agreement, promptly (and in any event within three (3) Business Days) upon Borrower becoming aware of the existence of any Event of Default or event which, with the giving of notice or passage of time, or both, would constitute an Event of Default, Borrower shall give written notice to the Lender of such occurrence, which such notice shall include a reasonably detailed description of such Event of Default or event which, with the giving of notice or passage of time, or both, would constitute an Event of Default.

6.7 Creation/Acquisition of Subsidiaries. In the event Borrower, or any of its Subsidiaries creates or acquires any Subsidiary, Borrower shall provide prior written notice to the Lender of the creation or acquisition of such new Subsidiary and take all such action as may be reasonably required by the Lender to cause each such Subsidiary to become a co-Borrower hereunder or to guarantee the Obligations of Borrower under the Loan Documents and, in each case, grant a continuing pledge and security interest in and to the assets of such Subsidiary (substantially as described on Exhibit A hereto); and Borrower (or its Subsidiary, as applicable) shall grant and pledge to the Lender a perfected security interest in the Shares of each such newly created Subsidiary; provided, however, that solely in the circumstance in which Borrower creates or acquires a Foreign Subsidiary, (i) such Foreign Subsidiary shall not be required to guarantee the Obligations of Borrower under the Loan Documents and grant a continuing pledge and security interest in and to the assets of such Foreign Subsidiary, and (ii) Borrower shall not be required to grant and pledge to the Lender a perfected security interest in more than sixty-five percent (65%) of the Shares of such Foreign Subsidiary.

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

9.RIGHTS AND REMEDIES

9.1 Rights and Remedies.

(a) The Lender, each of its permitted successors and assigns, and each holder of a Secured Promissory Note (i) consents to and approves each and all of the provisions of the Subordination Agreement and (ii) acknowledges that the terms of this Agreement, each Secured Promissory Note, and each other Loan Document, and the rights and remedies (including the exercise thereof) of the Lender, its permitted successors and assigns, and the holders of Secured Promissory Notes set forth herein and therein, are subject to the terms of the Subordination Agreement.

(b) Upon the occurrence and during the continuance of an Event of Default, the Lender may, without notice or demand, do any or all of the following: (i) deliver notice of the Event of Default to Borrower, (ii) by notice to Borrower declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations shall be immediately due and payable without any action by the Lender) or (iii) by notice to Borrower suspend or terminate the obligations, if any, of the Lender to advance money or extend credit for Borrower’s benefit under this Agreement or any other Loan Document (but if an Event of Default described in Section 8.5 occurs, all Obligations, if any, of the Lender to advance money or extend credit for Borrower’s benefit under this Agreement or under any other Loan Document shall be immediately terminated without any action by the Lender).

(c) Without limiting the rights of the Lender set forth in Section 9.1(b) above, upon the occurrence and during the continuance of an Event of Default, the Lender shall have the right, without notice or demand, to do any or all of the following:

(i) foreclose upon and/or sell or otherwise liquidate, the Collateral;

(ii) apply to the Obligations any amount held or controlled by the Lender owing to or for the credit or the account of Borrower; and/or

(iii) commence and prosecute an Insolvency Proceeding or consent to Borrower commencing any Insolvency Proceeding.

(d) Without limiting the rights of the Lender set forth in Sections 9.1(b) and (c) above, upon the occurrence and during the continuance of an Event of Default, the Lender shall have the right, without notice or demand, to do any or all of the following:

(i) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that the Lender considers advisable, notify any Person owing Borrower money of the Lender’s security interest in such funds, and verify the amount of such account;

(ii) 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 the Lender requests and make it available in a location as the Lender reasonably designates. The 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 the Lender a license to enter and occupy any of its premises, without charge, to exercise any of the Lender’s rights or remedies;

(iii) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, and/or advertise for sale, the Collateral. The Lender is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s and each of its Subsidiaries’ labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with the Lender’s

exercise of its rights under this Section 9.1, Borrower’s and each of its Subsidiaries’ rights under all licenses and all franchise agreements inure to the Lender;

(iv) demand and receive possession of Borrower’s Books;

(v) appoint a receiver to seize, manage and realize any of the Collateral, and such receiver shall have any right and authority as any competent court will grant or authorize in accordance with any applicable law, including any power or authority to manage the business of Borrower or any of its Subsidiaries; and

(vi) subject to clauses 9.1(b) and (c), exercise all rights and remedies available to the Lender and each Lender under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

9.2 Power of Attorney. Borrower hereby irrevocably appoints the Lender as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s or any of its Guarantor’s name on any checks or other forms of payment or security; (b) sign Borrower’s or any of its Guarantor’s name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms the Lender determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of the Lender or a third party as the Code or any applicable law permits. Borrower hereby appoints the Lender as its lawful attorney-in-fact to sign Borrower’s or any of its Guarantor’s name on any documents necessary to perfect or continue the perfection of the Lender’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied in full and the Lender is under no further obligation to make Credit Extensions hereunder. The Lender’s foregoing appointment as Borrower’s or any of its Guarantor’s attorney in fact, and all of the Lender’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been fully repaid and performed and the Lender’s obligation to provide Credit Extensions terminates.

9.3 Protective Payments. If Borrower or any of its Subsidiaries fail to obtain the insurance called for by Section 6.3 or fails to pay any premium thereon or fails to pay any other amount which Borrower or any of its Subsidiaries is obligated to pay under this Agreement or any other Loan Document, the Lender may obtain such insurance or make such payment, and all amounts so paid by the Lender are Obligations and immediately due and payable, bearing interest at the Default Rate, and secured by the Collateral. The Lender will make reasonable efforts to provide Borrower with notice of the Lender obtaining such insurance or making such payment at the time it is obtained or paid or within a reasonable time thereafter. No such payments by the Lender are

deemed an agreement to make similar payments in the future or the Lender’s waiver of any Event of Default.

9.4 Application of Payments and Proceeds. Notwithstanding anything to the contrary contained in this Agreement, upon the occurrence and during the continuance of an Event of Default, (a) Borrower irrevocably waives the right to direct the application of any and all payments at any time or times thereafter received by the Lender from or on behalf of Borrower or any of its Subsidiaries of all or any part of the Obligations, and, as between Borrower on the one hand and the Lender on the other, the Lender shall have the continuing and exclusive right to apply and to reapply any and all payments received against the Obligations in such manner as the Lender may deem advisable notwithstanding any previous application by the Lender, and (b) the net after tax proceeds of any sale of, or other realization upon all or any part of the Collateral shall be applied: first, to the Lender Expenses; second, to accrued and unpaid interest on the Obligations (including any interest which, but for the provisions of the United States Bankruptcy Code, would have accrued on such amounts); third, to the principal amount of the Obligations outstanding; and fourth, to any other indebtedness or obligations of Borrower owing to the Lender under the Loan Documents. Any balance remaining shall be delivered to Borrower or to whoever may be lawfully entitled to receive such balance or as a court of competent jurisdiction may direct.

9.5 Liability for Collateral. So long as the Lender complies with reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of the Lender, the 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 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. Failure by the Lender, 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 the Lender thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by the Lender and then is only effective for the specific instance and purpose for which it is given. The rights and remedies of the Lender under this Agreement and the other Loan Documents are cumulative. The Lender has all rights and remedies provided under the Code, any applicable law, by law, or in equity. The exercise by the Lender of one right or remedy is not an election, and the Lender’s waiver of any Event of Default is not a continuing waiver. The Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence.

9.7 Demand Waiver. Borrower waives, to the fullest extent permitted by law, 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 the Lender on which Borrower or any Subsidiary is liable.
