M.Condition of Books and Records.  The Debtor has maintained and shall maintain complete, accurate and up-to-date books, records, accounts, and other information relating to all Collateral in such form and in such detail as may be satisfactory to the Secured Party, and shall allow the Secured Party or its representatives at any reasonable time to examine and copy such books, records, accounts, and other information.

N.Right of Inspection.  At all reasonable times upon the request of the Secured Party, the Debtor shall allow the Secured Party or its representatives to visit any of the Debtor’s properties or locations so that the Secured Party or its representatives may confirm, inspect and appraise any of the Collateral.  The Debtor will reimburse the Secured Party upon demand for all cost and expenses incurred by the Secured Party in connection with any such inspection or examination conducted by the Secured Party.

A.Disposition of Collateral.  The Secured Party may sell, lease, or otherwise dispose of all or any part of the Collateral, in its then present condition or following any commercially

reasonable preparation or processing thereof, whether by public or private sale or at any brokers’ board, in lots or in bulk, for cash, on credit or otherwise, with or without representations or warranties, and upon such other terms as may be acceptable to the Secured Party, and the Secured Party may purchase at any public sale.  At any time when advance notice of sale is required, the Debtor agrees that ten days’ prior written notice shall be reasonable.  In connection with the foregoing, the Secured Party may:

5.rely conclusively upon the advice or instructions of any one or more brokers or other experts selected by the Secured Party to determine the method or manner of disposition of any of the Collateral and, in such event, any disposition of the Collateral by the Secured Party in accordance with such advice or instructions shall be deemed to be commercially reasonable.

B.Collection of Receivables.  The Secured Party may, but shall not be obligated to, take all actions reasonable or necessary to preserve, enforce or collect the Receivables, including without limitation, the right to notify account debtors and obligors on Receivables to make direct payment to the Secured Party, to permit any extension, compromise, or settlement of any of the Receivables for less than face value, or to sue on any Receivable, all without prior notice to the Debtor.

C.Proceeds.  The Secured Party may collect and apply all proceeds of the Collateral, and may endorse the name of the Debtor in favor of the Secured Party on any and all checks, drafts, money orders, notes, acceptances, or other instruments of the same or a different nature, constituting, evidencing, or relating to the Collateral.  The Secured Party may receive and open all mail addressed to the Debtor and remove therefrom any cash or non-cash items of payment constituting proceeds of the Collateral.

D.Insurance Adjustments.  The Secured Party may adjust, settle, and cancel any and all insurance covering any Collateral, endorse the name of the Debtor on any and all checks or drafts drawn by any insurer, whether representing payment for a loss or a return of unearned premium, and execute any and all proofs of claim and other documents or instruments of every kind required by any insurer in connection with any payment by such insurer.

The net proceeds of any disposition of the Collateral may be applied by the Secured Party, after deducting its reasonable expenses incurred in such disposition, to the payment in whole or in part of the Obligations in such order as the Secured Party may elect.  The enumeration of the foregoing rights and remedies is

not intended to be exhaustive, and the exercise of any right and/or remedy shall not preclude the exercise of any other rights or remedies, all of which are cumulative and non-exclusive.

SECTION 6.  OTHER PROVISIONS.

A.Amendment, Modification, and Waiver.  Without the prior written consent of the Secured Party, no amendment, modification, or waiver of, or consent to any departure by the Debtor from, any provision hereunder shall be effective.  Any such amendment, modification, waiver, or consent shall be effective only in the specific instance and for the specific purpose for which given.  No delay or failure by the Secured Party to exercise any remedy hereunder shall be deemed a waiver thereof or of any other remedy hereunder.  A waiver on any one occasion shall not be construed as a bar to or waiver of any remedy on any subsequent occasion.

B.Costs and Attorneys’ Fees.  Except as prohibited by law, if at any time the Secured Party employs counsel in connection with the creation, perfection, preservation, or release of the Secured Party’s security interest in the Collateral or the enforcement of any of the Secured Party’s rights or remedies hereunder, all of the Secured Party’s reasonable attorneys’ fees arising from such services and all expenses, costs, or charges relating thereto shall become part of the Obligations secured hereby and be paid by the Debtor on demand.

C.No Obligation to Make Loans.  Nothing contained herein or in any financing statement or other document executed or filed in connection herewith shall be construed to obligate the Secured Party to make any loans or advances to the Debtor, whether pursuant to a commitment or otherwise.

E.Performance by the Secured Party.  In the event the Debtor shall at any time fail to pay or perform punctually any of its duties hereunder, the Secured Party may, at its option and without notice to or demand upon the Debtor, without obligation and without waiving or diminishing any of its other rights or remedies hereunder, fully perform or discharge any of such duties.  All costs and expenses incurred by the Secured Party in connection therewith, together with interest thereon at four percent per annum in excess of the rate(s) of interest that would otherwise be in effect on that loan, shall become part of the Obligations secured hereby and be paid by the Debtor upon demand.

H.Continuing Effect.  This Security Agreement, the Secured Party’s security interest in the Collateral, and all other documents or instruments contemplated hereby shall continue in full force and effect until all of the Obligations have been satisfied in full, the Secured Party has no commitment to make any further advances to the Debtor, and the Debtor has sent a valid written demand to the Secured Party for termination of this Security Agreement.

I.Binding Effect.  This Security Agreement shall be binding upon and inure to the benefit of the Debtor and the Secured Party and their respective successors and assigns.

J.Security Agreement as Financing Statement and Authorization to File.  A photographic copy or other reproduction of this Security Agreement may be used as a financing statement.  In addition, the Debtor authorizes the Secured Party to prepare and file financing statements describing the Collateral, amendments thereto, and continuation statements and file any financing statement, amendment thereto or continuation statement electronically.  In addition, the Debtor authorizes the Secured Party to file financing statements describing any agricultural liens or other statutory liens held by the Secured Party.

M.Severability.  The determination that any term or provision of this Security Agreement is unenforceable or invalid shall not affect the enforceability or validity of any other term or provision hereof.

N.Marshalling.  Secured Party shall not be required to marshal any present or future collateral security (including, without limitation, this Agreement and the Collateral) for, or other

assurances of payment of, any or all of the Obligations or to resort to such collateral security or other assurances of payment in any particular order, and all of their respective rights and remedies under this Security Agreement and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising.  To the extent not prohibited by applicable law, the Debtor hereby agrees that it will not invoke any law relating to marshalling of collateral which might cause delay or impede the enforcement of any of the rights and/or remedies of the Secured Party under this Security Agreement or under any other agreement, document or instrument creating or evidencing any of Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extend not prohibited by applicable law, the Debtor hereby irrevocably waives the benefits of such laws.
