Section 1.1 Line of Credit.

Subject to the terms and conditions of this Agreement, Bank hereby agrees to make advances to Borrowers from time to time up to and including November 1, 2013, not to exceed at any time the aggregate principal amount of Ten Million Dollars ($10,000,000) (the “Line of Credit”), the proceeds of which shall be used for working capital and other general corporate purposes. Borrower’s obligation to repay advances under the Line of Credit shall be evidenced by a promissory note of even date herewith (as amended, restated, supplemented, extended, replaced, renewed or otherwise modified from time to time, the “Revolving Note”), all terms of which are incorporated herein by this reference. Each Borrower jointly and severally promises to pay the debts, liabilities and obligations arising under or in connection with this Agreement, the Revolving Note and the other Loan Documents (including principal, interest, fees, costs, and expenses) in full on the Maturity Date (as defined in the Revolving Note).

(b) Letter of Credit Subfeature. As a subfeature under the Line of Credit, Bank agrees from time to time during the term thereof to issue or cause an affiliate to issue standby or commercial letters of credit for the account of a Borrower (each, a “Letter of Credit” and collectively, “Letters of Credit”); provided however, that the aggregate undrawn amount of all outstanding Letters of Credit shall not at any time exceed Ten Million Dollars ($10,000,000); and provided, further, that no Letter of Credit shall be issued hereunder if, after giving effect to the issuance of such Letter of Credit, the Aggregate Outstanding Amount would exceed the amount of the Line of Credit. The form and substance of each Letter of Credit shall be subject to approval by Bank, in its sole discretion. Each Letter of Credit shall be issued for a term not to exceed one (1) year, as designated by Borrower; provided however, that no Letter of Credit shall have an expiration date subsequent to the maturity date of the Line of Credit. The undrawn amount of all issued and outstanding Letters of Credit shall be reserved under the Line of Credit and shall not be available for borrowings thereunder. Each Letter of Credit shall be subject to the additional terms and conditions of such letter of credit agreements, applications and any related documents required by Bank in connection with the issuance thereof.

Borrowers in accordance with the terms and conditions of this Agreement applicable to such advances; provided however, that if advances under the Line of Credit are not available, for any reason, at the time any drawing is paid, then Borrowers shall immediately pay to Bank the full amount drawn, together with interest thereon from the date such drawing is paid to the date such amount is fully repaid by Borrowers, at the rate of interest applicable to advances under the Line of Credit. In such event Borrowers agree that Bank, in its sole discretion, may debit any account maintained by any Borrower with Bank for the amount of any such drawing. As used herein, “Aggregate Outstanding Amount” means the sum of (i) the aggregate principal amount of all outstanding advances made by Bank under the foregoing clause (a) and (ii) the aggregate remaining available amount of all issued and outstanding Letters of Credit and Borrowers’ obligation to pay amounts drawn under Letters of Credit which have not yet been reimbursed with proceeds of an advance or otherwise.

Any portion of the unused fee under this clause (c) remaining unpaid on the Maturity Date shall be due and payable on such date.

(d) Letter of Credit Fees. Borrowers shall pay to Bank (i) fees upon the issuance or renewal of each Letter of Credit equal to the greater of (A) $500 and (B) one and one-tenth of one percent (1.10%) (computed on the basis of a 360-day year, actual days elapsed) of the face amount of such Letter of Credit, and (ii) fees upon the payment or negotiation of each drawing under each Letter of Credit and upon the occurrence of any other activity with respect to any Letter of Credit (including, without limitation, the transfer, amendment or cancellation of any Letter of Credit) determined in accordance with Bank’s standard fees and charges then in effect for such activity.

(d) Any default in the payment or performance of any obligation, or any defined event of default, under the terms of any contract, instrument or document (other than any of the Loan Documents) pursuant to which any Borrower, any guarantor hereunder or any general partner or joint venturer in any Borrower if a partnership or joint venture (with each such guarantor, general partner and/or joint venturer referred to herein as a “Third Party Obligor”) has incurred any debt or other liability to any person or entity, including Bank, and with respect to any such default that by its nature can be cured, such default shall continue for a period of thirty (30) days from its occurrence; provided, however, that any default which causes or results in the acceleration of any debt or other liability shall not be considered a default that by its nature can be cured, and shall result in an immediate Event of Default hereunder.

(e) Any Borrower or any Third Party Obligor shall become insolvent, or shall suffer or consent to or apply for the appointment of a receiver, trustee, custodian or liquidator of itself or any of its property, or shall generally fail to pay its debts as they become due, or shall make a general assignment for the benefit of creditors; any Borrower or any Third Party Obligor shall file a voluntary petition in bankruptcy, or seeking reorganization, in order to effect a plan or other arrangement with creditors or any other relief under the Bankruptcy Reform Act, Title 11 of the

fb.us.7363807.04

United States Code, as amended or recodified from time to time (“Bankruptcy Code”), or under any state or federal law granting relief to debtors, whether now or hereafter in effect; or any Borrower or any Third Party Obligor shall file an answer admitting the jurisdiction of the court and the material allegations of any involuntary petition; or any Borrower or any Third Party Obligor shall be adjudicated a bankrupt, or an order for relief shall be entered against any Borrower or any Third Party Obligor by any court of competent jurisdiction under the Bankruptcy Code or any other applicable state or federal law relating to bankruptcy, reorganization or other relief for debtors.

(f) The filing of a notice of judgment lien against any Borrower or any Third Party Obligor; or the recording of any abstract of judgment against any Borrower or any Third Party Obligor in any county in which such Borrower or such Third Party Obligor has an interest in real property; or the service of a notice of levy and/or of a writ of attachment or execution, or other like process, against the assets of any Borrower or any Third Party Obligor; or the entry of a judgment against any Borrower or any Third Party Obligor; or any involuntary petition or proceeding pursuant to the Bankruptcy Code or any other applicable state or federal law relating to bankruptcy, reorganization or other relief for debtors is filed or commenced against any Borrower or any Third Party Obligor.

(g) There shall exist or occur any event or condition that Bank in good faith believes likely to materially impair, or is substantially likely to materially impair, the prospect of payment or performance by any Borrower, any Third Party Obligor, or the general partner of either if such entity is a partnership, of its obligations under any of the Loan Documents.

(h) The dissolution or liquidation of any Borrower or any Third Party Obligor if a corporation, partnership, joint venture or other type of entity; or any Borrower or any such Third Party Obligor, or any of its directors, stockholders or members, shall take action seeking to effect the dissolution or liquidation of such Borrower or such Third Party Obligor.

Section 6.2 Remedies. Upon the occurrence of any Event of Default, Bank may exercise any or all of the following rights and remedies: (a) all indebtedness of Borrowers under each of the Loan Documents, any term thereof to the contrary notwithstanding, may at Bank’s option and without notice become immediately due and payable without presentment, demand, protest or notice of dishonor, all of which are hereby expressly waived by each Borrower; (b) the obligation, if any, of Bank to extend any further credit under any of the Loan Documents may immediately cease and terminate; (c) Bank may have all rights, powers and remedies available under each of the Loan Documents, or accorded by law, including without limitation the right to resort to any or all security for any credit subject hereto and to exercise any or all of the rights of a beneficiary or secured party pursuant to applicable law; and (d) Bank may apply for the appointment of, or taking possession by, a trustee, receiver, liquidator or other similar official of any Borrower to hold or liquidate all or any substantial part of the properties or assets of such Borrower. Borrowers hereby consent to such appointment and agrees to execute and deliver any and all documents requested by Bank relating to the appointment of such trustee, receiver, liquidator or other similar official (whether by joining in a petition for the appointment of such an official, by entering no contest to a petition for the appointment of such an official, or otherwise, as appropriate under applicable law). All rights, powers and remedies of Bank may be exercised at any time by Bank and from time to time after the occurrence of an Event of Default, are cumulative and not exclusive, and shall be in addition to any other rights, powers or remedies provided by law or equity.

Section 6.3 Right of Setoff. If an Event of Default shall have occurred, Bank and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional

fb.us.7363807.04

or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by Bank or any such affiliate to or for the credit or the account of Borrowers against any and all of the obligations of Borrowers now or hereafter existing under this Agreement or any other Loan Document to Bank or any such affiliate, irrespective of whether or not Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of Borrowers may be contingent or unmatured or are owed to a branch or office of Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender Party and its affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that Bank or its affiliates may have. Bank will notify Borrowers promptly after any such setoff and application; provided, however, that the failure to give such notice shall not affect the validity of such setoff and application.

MISCELLANEOUS

Section 7.10 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Minnesota.

Section 7.11 Arbitration.

(a)  Arbitration. The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to (i) any credit subject hereto, or any of the Loan Documents, and their negotiation, execution, collateralization, administration, repayment,

fb.us.7363807.04

modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests for additional credit.

(b) Governing Rules. Any arbitration proceeding will (i) proceed in a location in Minnesota selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(c) No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration requirement does not limit the right of any party to (i) foreclose against real or personal property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph.

(d) Arbitrator Qualifications and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in the State of Minnesota or a neutral retired judge of the state or federal judiciary of Minnesota, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of Minnesota and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Minnesota Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a

fb.us.7363807.04

waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

(e) Discovery. In any arbitration proceeding, discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party’s presentation and that no alternative means for obtaining information is available.

(f) Class Proceedings and Consolidations. No party hereto shall be entitled to join or consolidate disputes by or against others in any arbitration, except parties who have executed any Loan Document, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of the general public or in a private attorney general capacity.

(g) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration proceeding.

(h) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.

Section 7.12 Joint and Several Liability. Each Borrower agrees that it is jointly and severally liable for, and absolutely and unconditionally guarantees to Bank the prompt payment and performance of, all loans, debts, principal, interest, reimbursement or indemnification obligations, premiums, liabilities, obligations, fees, expenses, guaranties and all covenants and duties of any other kind and description owing by any Borrower, whether direct or indirect, absolute or contingent, due or to become due, sole, joint, several or joint and several, now existing or hereafter arising, pursuant to or evidenced by this Agreement or any other Loan Document. Each Borrower agrees that its guaranty obligations hereunder constitute a continuing guaranty of payment and not of collection, that such obligations shall not be discharged until cash payment in full of the obligations, and that such obligations are absolute and unconditional, irrespective of (a) the genuineness, validity, regularity, enforceability, subordination or any future modification of, or change in, any obligations or Loan Document, or any other document, instrument or agreement to which any Borrower is or may become a party or be bound; (b) the absence of any action to enforce this Agreement (including this Section) or any other Loan Document, or any waiver, consent or indulgence of any kind by Bank with respect thereto; (c) the existence, value or condition of, or failure to perfect any of Bank’s liens or to preserve rights against, any security or guaranty for the obligations or any action, or the absence of any action, by Bank in respect thereof (including the release of any security or guaranty); (d) the insolvency of any Borrower; (e) any election by Bank in an insolvency proceeding for the application of Section 1111(b)(2) of the Bankruptcy Code; (f) any borrowing or grant of a lien, security interest or other encumbrance by any other Borrower, as debtor-in-possession under Section 364 of the Bankruptcy Code or otherwise; (g) the disallowance of any claims of Bank against any Borrower for the repayment of any obligations under Section 502 of the Bankruptcy Code or otherwise; or (h) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, except cash payment in full of all obligations.
