Section 4.5 Mandatory Prepayments. The Borrower shall prepay the Obligations as provided in the Subordination and Intercreditor Agreement.

ARTICLE 5 COLLATERAL SECURITY

Section 5.1 Composition of the Collateral.

stand as one general, continuing collateral security for all of the Obligations, and may be retained by the Lender until all Obligations have been satisfied in full, and the Discretionary Facility has terminated.

Section 5.2 Rights in Property Held by the Lender.

ARTICLE 9 EVENTS OF DEFAULT AND REMEDIES

Section 9.1 Events of Default. The occurrence of any one or more of the following events shall constitute an Event of Default:

(a) The Borrower shall fail to make when due, whether by acceleration or otherwise, any payment of the Obligations; or

(b) An Act of Bankruptcy shall occur with respect to the Borrower; or

(c) Any representation or warranty made by the Borrower in the Loan Documents or in any certificate, statement, report or other writing furnished by the Borrower to the Lender pursuant to the Loan Documents or any other instrument,

document or agreement shall prove to have been false or misleading in any material respect on the date as of which the facts set forth are stated or certified or deemed to have been stated or certified; or

In addition to the remedies set forth in Section 9.2, the Lender or any other holder of the Note may offset any and all obligations of the Lender or such other holder of the Note, against the Indebtedness then owed by the Borrower to the Lender. Nothing in this Agreement shall be deemed a waiver or prohibition of the Lender’s rights offset or counterclaim, which right the Borrower hereby grants to the Lender.

ARTICLE 10 MISCELLANEOUS

Section 10.1 Waiver and Amendment. No failure on the part of the Lender or the holder of the Note to exercise and no delay in exercising any power or right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any power or right preclude any other or further exercise thereof or the exercise of any other power or right. The remedies herein and in any other instrument, document or

agreement delivered or to be delivered to the Lender hereunder or in connection herewith are cumulative and not exclusive of any remedies provided by law. No notice to or demand on the Borrower not required hereunder or under the Note shall in any event entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of the Lender or the holder of the Note to any other or further action in any circumstances without notice or demand. No amendment, modification or waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall be effective unless the same shall be in writing and signed by the Lender, and then such amendment, modifications, waiver or consent shall be effective only in the specific instances and for the specific purpose for which given. Xxxxxx’x approval of any Borrower corporate action, in his capacity as a director of Borrower, whether by written action or otherwise, is not a sufficient waiver or consent to satisfy any waiver or consent requirement with respect to any Obligations.

Section 10.2 Expenses and Indemnities. Whether or not any the Loan is made hereunder, the Borrower agrees to reimburse the Lender upon demand for all reasonable expenses paid or incurred by either the Lender or Xxxxxx (including filing and recording costs and fees and expenses of legal counsel and financial advisor of each of Lender and Xxxxxx) in connection with the preparation, review, execution, delivery, amendment, modification, interpretation, collection and enforcement of the Loan Documents and other work on possible financing activities related to the Borrower. The Borrower agrees to pay, and save the Lender harmless from all liability for, any stamp or other taxes which may be payable with respect to the execution or delivery of the Loan Documents. The Borrower agrees to indemnify and hold the Lender harmless from any loss or expense which may arise or be created by the acceptance of instructions for making Loans or disbursing the proceeds thereof. The Borrower agrees to indemnify and hold the Lender and Xxxxxx harmless from any obligation to pay any fees or commissions to any broker or finder in connection with the transactions contemplated in the Loan Documents. The Borrower shall indemnify and hold harmless the Lender and its respective Affiliates, and each such Person’s respective officers, directors, employees, attorneys, agents and representatives (each, an “Indemnified Person”), from and against any and all suits, actions, proceedings, claims, damages, losses, liabilities and expenses (including reasonable attorneys’ fees and disbursements and other costs of investigation or defense, including those incurred upon any appeal) that may be instituted or asserted against or incurred by any such Indemnified Person as the result of any representation or warranty made by the Borrower in the Loan Documents or in any certificate, statement, report or other writing furnished by the Borrower to the Lender or Xxxxxx pursuant to the Loan Documents or any other instrument, document or agreement shall prove to have been false or misleading. The obligations of the Borrower under this Section 10.2 shall survive any termination or expiration of the Discretionary Facility and payment in full of the Obligations.

Section 10.3 Notices. Except when telephonic notice is expressly authorized by this Agreement, any notice or other communication to any party in connection with this Agreement shall be in writing and shall be sent by manual delivery, telegram, telex, facsimile transmission, overnight courier or United States mail (postage prepaid) addressed to such party at the address specified on the signature page hereof, or at such other address as such party shall have specified to the other party hereto in writing. All periods of notice shall be measured from the date of delivery thereof if manually delivered, from the date of sending thereof if sent by telegram, telex or facsimile transmission, from a first Business Day after the date of sending if sent by overnight

courier, or from four days after the date of mailing if mailed; provided, however, that any notice to the Lender under Article 2 hereof shall be deemed to have been given only when received by the Lender. If notice to the Borrower of any intended disposition of the Collateral or any other intended action is required by law in a particular instance, such notice shall be deemed commercially reasonable if given at least ten calendar days prior to the date of intended disposition or other action.

Section 10.4 Successors. This Agreement shall be binding on the Borrower and the Lender and their respective successors and assigns, and shall inure to the benefit of the Borrower and the Lender, and the successors and assigns of the Lender. The Borrower shall not assign its rights or duties hereunder without the written consent of the Lender.

Section 10.5 Participations and Information. The Lender may sell participation interests in any or all of the Loans and in all or any portion of the Discretionary Facility to any Person. The Lender may furnish any information concerning the Borrower in the possession the Lender from time to time to participants and prospective participants and may furnish information in response to credit inquiries.

Section 10.6 Severability. Any provision of the Agreement which is prohibited or unenforceable in any jurisdiction shall, in such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

Section 10.7 Captions. The captions or headings herein are for convenience only and in no way define, limit or describe the scope or intent of any provision of this Agreement.

Section 10.8 Entire Agreement. This Agreement and the Note, and the other Loan Documents, embody the entire agreement and understanding between the Borrower and the Lender with respect to the subject matter hereof and thereof. This Agreement supersedes all prior agreements and understandings relating to the subject matter hereof.

Section 10.9 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument, and either of the parties hereto may execute this Agreement by signing any such counterpart.

Section 10.10 Governing Law. The validity, construction and enforceability of this Agreement and the Note shall be governed by the internal laws of the State of Minnesota, without giving effect to conflict of laws principles thereof.

Section 10.11 Financing With More Preferable Terms. To the extent any financing obtained by Borrower has more favorable terms than terms provided to Lender with respect to any Obligations, all as reasonably determined by Lender, then in the Lender’s discretion, such terms shall automatically be adopted into agreements evidencing the Obligations. Borrower will provide written notice to the Lender of any financing obtained by Borrower, describing the nature thereof and what terms may be more preferable than those existing with respect to the Obligations. Contemporaneously with such financing, Borrower will provide copies of all documents evidencing such financing to Lender. Borrower will execute, deliver or endorse any and all instruments, documents, assignments, security agreements, warrants, notes and other

agreements and writings which Lender may at any time reasonably request in order to secure, protect, perfect or enforce the rights under this Section. Nothing in this Section shall be deemed to waive the provisions of this Agreement or any other agreement requiring the Lender’s prior written consent to obtaining any such financing.
