REPRESENTATIONS AND COVENANTS OF GRANTOR

Grantor represents, warrants and covenants that:

3.1 Authorization. The execution and performance of this Agreement have been duly authorized by all necessary action and do not and will not: (a) require any consent or approval of the stockholders or members of any entity, or the consent of any governmental entity which has not been obtained; or (b) violate any provision of any indenture, contract, agreement or instrument to which it is a party or by which it is bound.

3.2 Title to Collateral. Grantor has good and marketable title to all of the Collateral and none of the Collateral is subject to any security interest except for the security interest created pursuant to this Agreement or other security interests permitted by the Loan Agreement (such other security interests being “Permitted Liens”).

3.3 Disposition or Encumbrance of Collateral. Grantor will not encumber, sell or otherwise transfer or dispose of the Collateral without the prior written consent of Lender except as provided in this Section or for Permitted Liens. Until a Default or Event of Default has occurred and is continuing, Grantor may: (a) sell Collateral consisting of: (i) Inventory in the ordinary course of business provided that Grantor receives as consideration for such sale an

4

amount not less than the fair market value of the Inventory at the time of such sale; and (ii) Equipment and Fixtures which in the judgment of Grantor have become obsolete or unusable in the ordinary course of business, provided that all net Proceeds of such sales of Equipment and Fixtures are delivered directly to Lender for application to the Obligations in such order as the Lender may elect; and (b) grant security interests in Equipment and Fixtures in order to secure permitted by the proviso clause to Section 8(b) of the Loan Agreement.

3.4 Validity of Accounts. Grantor warrants that all Collateral consisting of Accounts, Chattel Paper and Instruments included in Grantor’s schedules, financial statements or books and records are bona fide existing obligations created by the sale and actual delivery of Inventory or the rendition of services to customers in the ordinary course of business, which Grantor then owns free and clear of any security interest other than the security interest created by this Agreement or other Permitted Liens, and which are then unconditionally owing to Grantor without defenses, offset or counterclaim except those arising in the ordinary course of business that are immaterial in the aggregate and that the unpaid principal amount of any such Chattel Paper or Instrument and any security therefor is and will be as represented to Lender on the date of the delivery thereof to Lender.

3.5 Maintenance of Tangible Collateral. Grantor will maintain the tangible Collateral in good condition and repair. At the time of attachment and perfection of the security interest granted pursuant hereto and thereafter, all tangible Collateral will be located and will be maintained only at locations where the Lender can perfect its security interest by the filing of a financing statement with the Minnesota Secretary of State. Except as otherwise permitted by Section 3.3 or by the proviso clause to this Section. Grantor will not remove such Collateral from such locations unless, prior to any such removal, Grantor has given written notice to Lender of the location or locations to which Grantor desires to remove the Collateral, Lender has given its written consent to such removal, and Grantor has delivered to Lender acknowledgment copies of financing statements (or comparable filings in Canada) filed where appropriate to continue the perfection of Lender’s security interest as a first priority security interest on such Collateral; provided, however, that Grantor may remove Equipment to foreign jurisdictions (other than Canada) so long as the aggregate fair market value of all Equipment located in such foreign jurisdictions does not exceed $250,000.00 for the Borrowers on a combined basis. Lender’s security interest attaches to all of the Collateral wherever located and Grantor’s failure to inform Lender of the location of any item or items of Collateral shall not impair Lender’s security interest thereon.

3.6 Notation on Chattel Paper. For purposes of the security interest granted pursuant to this Agreement, Lender has been granted a direct security interest in all Chattel Paper constituting part of the Collateral and such Chattel Paper is not claimed merely as Proceeds of Inventory.

Grantor will not execute any copies of such Chattel Paper constituting part of the Collateral other than those which are clearly marked as a copy. Lender may stamp any such Chattel Paper with a legend reflecting Lender’s security interest therein.

5

Proceeds (for example, money and checks) shall be deposited in Deposit Accounts with the Depository Bank. Grantor has granted to the Lender a direct security interest in all Deposit Accounts constituting part of the Collateral and such Deposit Accounts are not claimed merely as Proceeds of other Collateral.

3.8 Protection of Collateral. All expenses of protecting, storing, warehousing, insuring, handling and shipping of the Collateral, all costs of keeping the Collateral free of any liens, encumbrances and security interests prohibited by this Agreement and of removing the same if they should arise, and any and all excise, property, sales and use taxes imposed by any state, federal or local authority on any of the Collateral or in respect of the sale thereof, shall be borne and paid by Grantor and if Grantor fails to promptly pay any thereof when due, Lender may, at its option, but shall not be required to pay the same whereupon the same shall constitute Obligations and shall bear interest at the Default Rate specified in the Revolving Credit Note (the “Interest Rate”) and shall be secured by the security interest granted hereunder.

3.9 Insurance. Grantor will procure and maintain, or cause to be procured and maintained, insurance issued by responsible insurance companies insuring the Collateral against damage and loss by theft, fire, collision (in the case of motor vehicles), and such other risks as are usually carried by owners of similar properties or as may be requested by Lender in an amount equal to the replacement value thereof, and, in any event, in an amount sufficient to avoid the application of any co-insurance provisions and payable, in the case of any loss in excess of $10,000.00, to Grantor and Lender jointly. All such insurance shall contain an agreement by the insurer to provide Lender with 30 days’ prior notice of cancellation and an agreement that the interest of Lender shall not be impaired or invalidated by any act or neglect of Grantor nor by the occupation of the premises wherein such Collateral is located for purposes more hazardous than are permitted by said policy. Grantor will maintain, with financially sound and reputable insurers, insurance with respect to its properties and business against such casualties and contingencies of such types (which may include, without limitation, public and product liability, larceny, embezzlement, business interruption or other criminal misappropriation insurance) and in such amounts as may from time to time be reasonably required by Lender. Grantor will deliver evidence of such insurance and the policies of insurance or copies thereof to Lender upon request.

3.10 Compliance with Law. Grantor will not use the Collateral, or knowingly permit the Collateral to be used, for any unlawful purpose or in violation of any federal, state or municipal law.

6

Collateral at any time and from time to time as Lender and its representatives may request.

3.12 Notice of Default. Immediately upon any officer of Grantor becoming aware of the existence of any Default or Event of Default, Grantor will give notice to Lender that such Default or Event of Default exists, stating the nature thereof, the period of existence thereof, and what action Grantor proposes to take with respect thereto.

3.13 Additional Documentation. Grantor will execute, from time to time, and authorizes Lender to execute from time to time as Grantor’s attorney-in-fact and/or file, such financing statements, assignments, and other documents covering the Collateral, including Proceeds, as Lender may request in order to create, evidence, perfect, maintain or continue its security interest in the Collateral (including additional Collateral acquired by Grantor after the date hereof), and Grantor will pay the cost of filing the same in all public offices in which Lender may deem filing to be appropriate and will notify Lender promptly upon acquiring any additional Collateral that may require an additional filing. Upon request, Grantor will deliver to Lender all Grantor’s Documents, Chattel Paper and Instruments constituting part of the Collateral.

The location of the chief executive office of Grantor is located in the State set forth in the preamble hereto and will not be changed from such state without 30 days’ prior written notice to Lender.

Grantor’s State of organization is the State set forth in the preamble hereto and such State has been its State of organization since the date of Grantor’s organization except as set forth on Exhibit A attached hereto. Grantor will not change its State of organization from such State without 30 days’ prior written notice to Lender, Lender has given its written consent to such change, and Grantor has delivered to Lender acknowledgment copies of financing statements filed where appropriate to continue the perfection of Lender’s security interest as a first priority security interest therein.

3.15 Name of Grantor. Grantor’s exact legal name and type of legal entity is as set forth in the preamble hereto. Grantor will not change its legal name without 30 days’ prior written notice to the Lender, the Lender has given its written consent to such change, and Grantor has delivered to the Lender acknowledgment copies of financing statements filed where appropriate to continue the perfection of the Lender’s security interest as a first priority security interest in the Collateral. Grantor has not used any other name within the past five years except those described on Exhibit A attached hereto. Neither Grantor nor, to Grantor’s knowledge, any predecessor in title to any of the Collateral has executed any financing statements or security

7

agreements presently effective as to the Collateral except those described on Exhibit A attached hereto.

3.16 Disputes. Etc. Grantor shall advise Lender promptly of Inventory in excess of $10,000.00 for any one customer in any fiscal year or in excess of $25,000.00 in the aggregate for all customers in any fiscal year which are returned by a customer(s) or otherwise recovered from such customer(s) and unless instructed to deliver such Inventory to Lender, Grantor shall resell such Inventory for Lender and assign or deliver to Lender the resulting Accounts or other Proceeds. Grantor shall also advise Lender promptly of all disputes and claims in excess of $10,000.00 for any one obligor on the Collateral in any fiscal year or in excess of $25,000.00 in the aggregate for all obligors in any fiscal year and settle or adjust them at no expense to Lender. After the occurrence and during the continuance of an Event of Default, Lender may at all times settle or adjust such disputes and claims directly with the customers for amounts and upon terms which Lender considers commercially reasonable. No discount, credit, allowance, adjustment or return shall be granted by Grantor to any customer without Lender’s written consent other than discounts, credits, allowances, adjustments and returns made or granted by Grantor in the ordinary course of business prior to the occurrence and during the continuance of an Event of Default.

3.17 Power of Attorney. Grantor appoints Lender, or any other person whom Lender may from time to time designate, as Grantor’s attorney with power, to: (a) endorse Grantor’s name on any checks, notes, acceptances, drafts or other forms of payment or security evidencing or relating to any Collateral that may come into Lender’s possession; (b) sign Grantor’s name on any invoice or bill of lading relating to any Collateral, on drafts against customers, on schedules and confirmatory assignments of Accounts, Chattel Paper, Documents or other Collateral, on notices of assignment, financing statements under the UCC and other public records, on verifications of accounts and on notices to customers; (c) notify the post office authorities to change the address for delivery of Grantor’s mail to an address designated by Lender; (d) receive and open all mail addressed to Grantor; (e) send requests for verification of Accounts, Chattel Paper, Instruments or other Collateral to customers; and (f) do all things necessary to carry out this Agreement.

ARTICLE IV

COLLECTIONS

Except as otherwise provided in this Article IV, Grantor shall continue to collect, at its own expense, all amounts due or to become due to Grantor under the Accounts constituting part of the Collateral and all other Collateral. In connection with such collections, Grantor may take (and, at Lender’s direction given after the occurrence and during the continuance of an Event of Default, shall take) such action as Grantor or Lender may deem necessary or advisable to enforce collection of the Accounts and such other Collateral; provided, however, that Lender shall have the right at any time after the occurrence and during the continuance of an Event of Default, without giving written notice to Grantor of Lender’s intention to do so, to notify the account debtors under any Accounts or obligors with respect to such other Collateral of the assignment of such Accounts and such other Collateral to Lender and to direct such account debtors or obligors to make payment of all amounts due or to become due to Grantor thereunder directly to Lender and, upon such notification and at the expense of Grantor, to enforce collection of any such Accounts or other Collateral, and to adjust, settle or compromise the amount or payment thereof in the same manner and to the same extent as Grantor might have done, but unless and until Lender does so or gives Grantor other instructions, Grantor shall make all collections for Lender. In addition to its rights under the preceding sentence to this Section, Lender, at any time after the occurrence and during the continuance of a Default or Event of Default, may require that Grantor instruct all current and future account debtors and obligors on other Collateral to make all payments directly to a lockbox (the “Lockbox”) controlled by Lender. All payments received in the Lockbox shall be transferred to a special bank account (the “Collateral Account”) maintained for the benefit of Lender subject to withdrawal by Lender only. Grantor shall immediately deposit in the Collateral Account all full and partial payments on any Collateral received by Grantor to Lender in their original form, except for endorsements where necessary. Lender shall apply all collections on the Collateral delivered to it or deposited in the Collateral Account as provided in the Collateral Account Agreement and any such amount applied to the payment of the Obligations may be applied in such order as Lender may elect; provided, however, that after an Event of Default has occurred and is continuing, Lender shall apply all collections in accordance with Section 7.7. Until such payments are so delivered to Lender, such payments shall be held in trust by Grantor for and as Lender’s property, and shall not be commingled with any funds of Grantor. Any application of any collection to the payment of any Obligation is conditioned upon final payment of any check or other instrument.

ARTICLE V

ASSIGNMENT OF INSURANCE

Grantor hereby assigns to Lender, as additional security for payment of the Obligations, any and all monies due or to become due under, and any and all other rights of Grantor with respect to, any and all policies of insurance covering the Collateral. So long as no Default or Event of Default has occurred and is continuing, Grantor may itself adjust and collect for any losses of up to an aggregate amount of $10,000.00 for all occurrences during any of Grantor’s fiscal years and Grantor may use the resulting Insurance Proceeds for the replacement, restoration or repair of the Collateral. After the occurrence and during the continuance of a

12

Default or an Event of Default, or after the aggregate amount of losses arising out of all occurrences during any of Grantor’s fiscal years exceeds $10,000.00, Lender may (but need not) in its own name or in Grantor’s name execute and deliver proofs of claim, receive such monies, and settle or litigate any claim against the issuer of any such policy and Grantor directs the issuer to pay any such monies directly to Lender and Lender, at its sole discretion and regardless of whether Lender exercises its right to collect Insurance Proceeds under this Section, may apply any Insurance Proceeds to the payment of the Obligations, whether due or not, in such order and manner as Lender may elect or may permit Grantor to use such Insurance Proceeds for the replacement, restoration or repair of the Collateral.

ARTICLE VI

EVENTS OF DEFAULT

The occurrence of any Event of Default as defined in the Loan Agreement shall constitute an Event of Default hereunder (“Event of Default”).

ARTICLE VII

RIGHTS AND REMEDIES ON DEFAULT

Upon the occurrence of an Event of Default, and at any time thereafter until such Event of Default is cured to the satisfaction of Lender, and in addition to the rights granted to Lender under Articles IV and V hereof, Lender may exercise any one or more of the following rights and remedies:

7.1 Acceleration of Obligations. Declare any and all Obligations to be immediately due and payable, and the same shall thereupon become immediately due and payable without further notice or demand.

7.2 Right of Offset. Offset any deposits, including unmatured time deposits, then maintained by Grantor with Lender, whether or not then due, against any indebtedness then owed by Grantor to Lender whether or not then due.

7.3 Deal with Collateral. In the name of Grantor or otherwise, demand, collect, receive and give receipt for, compound, compromise, settle and give acquittance for and prosecute and discontinue any suits or proceedings in respect of any or all of the Collateral.

7.4 Realize on Collateral. Take any action which Lender may deem reasonably necessary or desirable in order to realize on the Collateral, including, without limitation, the power to perform any contract, to endorse in the name of Grantor any checks, drafts, notes, or other instruments or documents received in payment of or on account of the Collateral. Lender may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. Lender may sell the Collateral without giving any warranties as to the Collateral. Lender may specifically disclaim any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

Grantor hereby agrees to indemnify Lender against all liability arising in connection with or on account of any of the Collateral, except for any such liabilities arising on account of Lender’s negligence or willful misconduct.

8.2 No Waiver. Lender shall not be deemed to have waived any of its rights hereunder or under any other agreement, instrument or paper signed by Grantor unless such waiver is in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A waiver on any

16

one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion.

8.3 Remedies Cumulative. All rights and remedies of Lender shall be cumulative and may be exercised singularly or concurrently, at their option, and the exercise or enforcement of any one such right or remedy shall not bar or be a condition to the exercise or enforcement of any other.

8.4 Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the laws of the State of Minnesota, except to the extent that the perfection of the security interest hereunder, or the enforcement of any remedies hereunder, with respect to any particular Collateral shall be governed by the laws of a jurisdiction other than the State of Minnesota.

8.5 Expenses. Grantor agrees to pay the reasonable attorneys’ fees and legal expenses incurred by Lender in the exercise of any right or remedy available to it under this Agreement, whether or not suit is commenced, including, without limitation, attorneys’ fees and legal expenses incurred in connection with any appeal of a lower court’s order or judgment.

Wherever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

8.9 No Obligation to Pursue Others. Lender has no obligation to attempt to satisfy the Obligations by collecting them from any other person liable for them and Lender may release, modify or waive any Collateral provided by any other person to secure any of the Obligations, all without affecting Lender’s rights against Grantor. Grantor waives any right it may have to require Lender to pursue any third person for any of the Obligations.
