4.             Each right to payment and each instrument, document, chattel paper and other agreement constituting or evidencing Collateral is (or will be when arising or issued) a valid, genuine and legally enforceable obligation, subject to no defense, set-off or counterclaim (other than those arising in the ordinary course of business) of the account debtor or other obligor named therein or in Borrower’s records pertaining thereto as being obligated to pay such obligation.  Borrower will not agree to any material modification, amendment or cancellation of any such obligation without Secured Party’s prior written consent, and will not subordinate any such right to payment to claims of other creditors of such account debtor or other obligor.

8.             Upon Secured Party’s request (whether a Default as hereinafter defined, has occurred) Borrower will promptly deliver to Secured Party any instrument, document or chattel paper constituting Collateral.

9.             Upon Borrower’s Default in performing its obligations hereunder, Secured Party shall have the authority, but shall not be obligated to:  (i) effect such insurance and necessary repairs and pay the premiums therefor and the costs thereof; (ii) pay and discharge any fees, assessments, charges, taxes, liens and encumbrances on the Collateral; and (iii) notify the appropriate governmental authority or other obligor to remit directly to Secured Party or its order any bio-energy subsidy or other government entitlement, subsidy, payment or program right constituting part of the Collateral.  All sums so advanced or paid by the Secured Party shall be payable by Borrower on demand with interest at the highest rate then charged on the Secured Obligations (but not exceeding the maximum rate allowed by law) and shall be a part of the Secured Obligations.

10.           Borrower will not sell, lease or otherwise dispose of the Collateral other than in the ordinary course of its business at prices constituting the then fair market value thereof.

11.           The Secured Party shall have the authority (whether or not a Default has occurred) but shall not be obligated to:  (a) notify any or all account debtors and obligors on instruments constituting Collateral of the existence of the Secured Party’s security interest and if a Default has occurred to pay or remit all sums due or to become due directly to the Secured Party or its nominee; (b) place on any chattel paper received as proceeds or otherwise constituting Collateral, a notation or legend showing the Secured Party’s security interest; (c) if a Default has occurred, in the name of the Borrower or otherwise, to demand, collect, receive and receipt for, compound, compromise, settle, prosecute and discontinue any suits or proceedings in respect of any or all of the Collateral; (d) if a Default has occurred, take any action which the Secured Party may deem necessary or desirable in order to realize on the Collateral, including, without limitation, the power to perform any contract, to indorse in the name of Borrower any checks, drafts, notes or other instruments or documents received in payment of or on account of the Collateral; (e) to place upon Borrower’s books and records relating to the accounts and general intangibles covered by the security interest granted hereby a notation or legend stating that such account or general intangible is subject to a security interest held by the Secured Party; and (f) after any Default, to enter upon and into and take possession of all or such part(s) of the properties of Borrower, including lands, plants, buildings, machinery, equipment and other property as may be necessary or appropriate in the judgment of the Secured Party to permit or enable the Secured Party to manufacture, produce, process, store or sell or complete the manufacture, production, processing, storing or sale of all or any part of the Collateral, as the Secured Party may elect, and to use and operate such properties for these purposes and for such length of time as the Secured Party may deem necessary or appropriate for these purposes without the payment of any compensation to Borrower thereof.

12.           Borrower will, if a Default has occurred and upon receipt of request from Secured Party, notify all account debtors and other obligors of the existence of the Secured Party’s security interest and direct such account debtors and other obligors to pay or remit all sums due or to become due directly to the Secured Party or its nominee.  Borrower will hold all of the proceeds of any collections and all returned and repossessed goods thereafter received by Borrower in trust for the Secured Party, and will not commingle the same with any other funds or property of the Borrower, and will deliver the same forthwith to the Secured Party at its request.  Nothing in this Section restricts Secured Party’s right to notify account debtors directly.

13.           Borrower will keep accurate books, records and accounts with respect to the Collateral, and with respect to the general business of Borrower, and will make the same available to the Secured Party at its request for examination and inspection; and will make and render to the Secured Party such reports, accountings and statements as the Secured Party from time to time may request with respect to the Collateral; and will permit any authorized representative of the Secured Party to examine and inspect during normal business hours, any and all premises where the Collateral is or may be kept or located.

14.           The occurrence of any of the events identified as a “Default” or “Event of Default” under the Loan Agreement will constitute a Default hereunder.

15.           Whenever a Default shall exist, the Secured Party may, at its option and without demand or notice, except to the extent notice is required under the Loan Agreement, declare all or any part of the Secured Obligations immediately due and payable, and the Secured Party may exercise, in addition to the rights and remedies granted hereby, all rights and remedies of a secured party under the Uniform Commercial Code or any other applicable law.  The Secured Party shall be entitled to recover its attorneys’ fees, service tax thereon, and all costs incurred by such attorneys, to the extent permitted by law.

16.           Borrower agrees, in the event of Default, to make the Collateral available to the Secured Party at a place or places to be designated by the Secured Party, which is reasonably convenient to both parties, and to pay all costs of the Secured Party, including reasonable attorneys’ fees, service tax thereon, and all costs incurred by such attorneys, in the collection of any of the Secured Obligations and the enforcement of any of the Secured Party’s rights.  If any notification of intended disposition of any of the Collateral is required by law, such notification shall be deemed properly given if mailed a reasonable time before such disposition, postage prepaid, addressed to the Borrower at the address shown above.  Secured Party’s duty of care with respect to Collateral in its possession shall be deemed fulfilled if Secured Party exercises reasonable care in physically safekeeping such Collateral or, in the case of Collateral in the custody or possession of a bailee or other third person, exercises reasonable care in the selection of the bailee or other third person, and Secured Party need not otherwise preserve, protect, insure or care for any Collateral.  Secured Party shall not be obligated to preserve any rights Borrower may have against prior parties, to realize on the Collateral at all or in any particular manner or order, or to apply any cash proceeds of Collateral in any particular order of application.  No delay or failure by the Secured Party in the exercise of any right or remedy shall constitute a waiver thereof, and no single or partial exercise by the Secured Party of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy.

17.           This Agreement is governed by the laws of the State of South Dakota, without regard to its conflicts or choice of law provisions.
