Upon the occurrence and during the continuance of any Event of Default, without Secured Party’s prior written consent, Debtor shall not grant any extension of the time of payment of any of the accounts, chattel paper, instruments or amounts due under any contract or document, compromise, compound or settle the same for less than the full amount thereof, release, wholly or partly, any person liable for the payment thereof, or allow any credit or discount whatsoever thereon other than trade discounts and rebates granted in the ordinary course of Debtor’s business.

Debtor agrees to render to Secured Party, at Debtor’s expense, such clerical and other assistance as may be reasonably requested with regard to the exercise of its rights pursuant to this paragraph.

(k)          Compliance with Laws, Etc. Debtor shall comply in all material respects with all laws, rules, regulations and orders of any governmental authority applicable to any part of the Collateral or to the operation of Debtor’s business; provided, however, that Debtor may contest any such law, rule, regulation or order in any reasonable manner which does not, in the reasonable opinion of Debtor, adversely affect Secured Party’s rights or the priority of its liens on the Collateral.

(l)           Payment of Obligations. Debtor shall pay before delinquency all obligations associated with the Collateral, including license fees, taxes, assessments and governmental charges or levies imposed upon the Collateral or with respect to any of its income or profits derived from the Collateral; as well as all claims of any kind (including, without limitation, claims for labor, materials and supplies) against or with respect to the Collateral, except that no such charge need be paid if (i) the validity or amount of such charge is being contested in good faith by appropriate proceedings, (ii) such proceedings do not involve any material danger of the sale, forfeiture or loss of any of the Collateral or any interest in the Collateral and (iii) such charge is adequately reserved against on Debtor’s books in accordance with generally accepted accounting principles.

(p)          Sale Upon Default. In the event of a default under the terms of this Agreement, the Warrant, Securities Purchase Agreement or Note, all of which are defined in the Securities Purchase Agreement, the Company and its management shall use their best efforts to secure a purchaser for the Collateral to obtain the maximum value of such Collateral for the Secured Party.

(a)          Powers. Debtor hereby appoints Secured Party and any officers or agents of Secured Party, with full power of substitution, as its attorney-in-fact with full irrevocable power and authority in the place of Debtor and in the name of Debtor or in its own name, so long as an Event of Default has occurred and is continuing, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any instrument which may be necessary or desirable to accomplish the purposes of this Agreement. Without limiting the foregoing, so long as an Event of Default has occurred and is continuing, Secured Party, in its discretion, will have the right, without notice to, or the consent of, Debtor, to do any of the following on Debtor’s behalf:

(i)           to pay or discharge any obligations in connection with the Collateral, including license fees and taxes or liens levied or placed on or threatened against the Collateral;

(ii)          to direct any party liable for any payment under any of the Collateral to make payment of any and all amounts due or to become due thereunder directly to Secured Party or as Secured Party directs;

(iii)        to ask for or demand, collect and receive payment of and receipt for any payments due or to become due at any time in respect of or arising out of any Collateral;

(iv)         to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to enforce any right in respect of any Collateral;

(v)          to defend any suit, action or proceeding brought against Debtor with respect to any Collateral;

(vi)         to settle, compromise or adjust any suit, action or proceeding described in subsection (v) above and, to give such discharges or releases in connection therewith as Secured Party may deem appropriate;

(vii)       to assign any license or patent right included in the Collateral of Debtor (along with the goodwill of the business to which any such license or patent right pertains), throughout the world for such term or terms, on such conditions and in such manner as Secured Party in its sole discretion determines; and

(viii)      to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral and to take, at Secured Party’s option and Debtor’s expense, any actions which Secured Party deems necessary to protect, preserve or realize upon the Collateral and Secured Party’s Liens on the Collateral and to carry out the intent of this Agreement, in each case to the same extent as if Secured Party were the absolute owner of the Collateral for all purposes.

Debtor hereby ratifies whatever actions Secured Party lawfully does or causes to be done in accordance with this Section 4. This power of attorney will be a power coupled with an interest and will be irrevocable.

(b)          No Duty on Secured Party’s Part. The powers conferred on Secured Party by this Section 4 are solely to protect Secured Party’s interest in the Collateral and do not impose any duty upon it to exercise any such powers. Secured Party will be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither Secured Party nor any of its officers, directors, employees or agents will, in the absence of willful misconduct or gross negligence, be responsible to Debtor for any act or failure to act pursuant to this Section 4.

5.            Expenses Incurred by Secured Party. If Debtor fails to perform or comply with any of its agreements or covenants contained in this Agreement, and Secured Party performs or complies, or otherwise causes performance or compliance, with such agreement or covenant in

accordance with the terms of this Agreement, then the reasonable expenses of Secured Party incurred in connection with such performance or compliance will be payable by Debtor to Secured Party on demand and will constitute obligations secured by this Agreement.

6.            Remedies. If an Event of Default has occurred and is continuing and uncured for thirty (30) days, Secured Party may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement relating to the Obligations, all rights and remedies of a Secured Party under the Uniform Commercial Code, as amended from time to time (the “Code”). Without limiting the foregoing, in such circumstances, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law) to or upon Debtor or any other Person (all of which demands, defenses, advertisements and notices are hereby waived), Secured Party may collect, receive, appropriate and realize upon any or all of the Collateral and/or may sell, lease, assign, give an option or options to purchase or otherwise dispose of and deliver any or all of the Collateral (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of Secured Party or elsewhere upon such terms and conditions as Secured Party may deem advisable, for cash or on credit or for future delivery without assumption of any credit risk. Secured Party will have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase all or any part of the Collateral so sold, free of any right or equity of redemption in Debtor, which right or equity is hereby waived or released. Secured Party will apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable expenses incurred therein or in connection with the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Secured Party under this Agreement (including, without limitation, reasonable attorneys’ fees and expenses) to the payment in whole or in part of the Obligations, in such order as Secured Party may elect, and only after such application and after the payment by Secured Party of any other amount required by any provision of law, need Secured Party account for the surplus, if any, to Debtor. To the extent permitted by applicable law, Debtor waives all claims, damages and demands it may acquire against Secured Party arising out of the exercise by Secured Party of any of its rights hereunder. If any notice of a proposed sale or other disposition of Collateral is required by law, such notice will be deemed reasonable and proper if given at least ten days before such sale or other disposition. Debtor will remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the reasonable fees and disbursements of any attorneys employed by Secured Party to collect such deficiency.

7.            Limitation on Duties Regarding Preservation of Collateral. The sole duty of Secured Party with respect to the custody, safekeeping and preservation of the Collateral, under the appropriate Code section or otherwise, will be to deal with it in the same manner as Secured Party deals with similar property for its own account. Neither Secured Party nor any of its employees, affiliates or agents will be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or will be under any obligation to sell or otherwise dispose of any Collateral upon the request of Debtor or otherwise.

8.            Powers Coupled with an Interest. All authorizations and agencies contained in this Agreement with respect the Collateral are irrevocable and powers coupled with an interest.

9.            No Waiver; Cumulative Remedies. Secured Party will not by any act (except by a written instrument pursuant to Section 10(a) hereof) of delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default under the Note or in any breach of any of the terms and conditions of this Agreement. No failure to exercise, nor any delay in exercising, on the part of Secured Party, any right, power or privilege hereunder will operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder will preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by Secured Party of any right or remedy under this Agreement on any one occasion will not be construed as a bar to any right or remedy that Secured Party would otherwise have on any subsequent occasion. The rights and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.

(a)          Amendments and Waivers. Any term of this Agreement may only be amended by prior written consent of Debtor and Secured Party. Any amendment or waiver effected in accordance with this Section 10(a) will be binding upon all of the parties hereto and their respective successors and assigns.

(b)          Transfer; Successors and Assigns. This Agreement will be binding upon and inure to the benefit of Debtor and Secured Party, and their respective successors or assigns. Debtor may not assign any of its rights or delegate any of its duties under this Agreement.

(c)         Governing Law. The interpretation and construction of this Agreement, and all matters relating hereto, shall be governed by the laws of the State of Missouri applicable to agreements executed and to be performed solely within such State without regard to conflicts of laws.

(d)         Jurisdiction. Any judicial proceeding brought against any of the parties to this Agreement on any dispute arising out of this Agreement or any matter related hereto may be brought in the courts of the State of Missouri, Greene County, or in the United States District Court for the Greene County, Missouri area, and, by execution and delivery of this Agreement, each of the parties to this Agreement accepts the exclusive jurisdiction of such courts, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. The prevailing party or parties in any such litigation shall be entitled to receive from the losing party or parties all costs and expenses, including reasonable counsel fees, incurred by the prevailing party or parties.

(e)         Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile), each of which will be an original, but all of which together will constitute one instrument.

(f)          Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

All notices and other communications required or permitted hereunder shall be delivered (i) in person, (ii) by way of recognized national overnight delivery service or (iii) by way of first class mail postage prepaid to the following addresses (or to such other address as may be designated in a properly delivered notice): Secured Party: Quest Capital Alliance II, L.L.C., 3140 E.

(i)          Entire Agreement. This Agreement and the other Loan Documents constitute the entire understanding and agreement between the parties with regard to the subject matter hereof and thereof and supersede all prior agreements, representations and undertakings of the parties, whether oral or written, with respect to such subject matter.
