3.

BORROWER'S WAIVERS. Except as otherwise required under this Agreement or by applicable law, Borrower agrees that Lender need not provide notice to Borrower about any action or inaction of Lender in connection with this Agreement, and waives any defense that may arise due to any action or inaction of Lender, including, without limitation, any failure or delay of Lender to realize upon the Collateral; and Borrower agrees to remain liable upon the Indebtedness regardless of Lender’s action or failure to act under this Agreement.

4.	GRANTOR'S REPRESENTATIONS AND WARRANTIES. Grantor warrants:

a.

That Grantor is the lawful owner of the Collateral and holds good and marketable title to the Collateral, free and clear of all liens, mortgages, claims, or other rights or interests asserted or which may be asserted at any time by any other person in or relating to the Collateral (collectively, “Encumbrances”) except the lien of this Agreement and any leases disclosed in writing and consented to by Lender (each, a “Lease” and together the “Leases”);

b.	That Grantor has the full right, power and authority to enter into this Agreement and to pledge the Collateral to Lender, has not received from or relied upon any representation by Lender about Borrower or Borrower's creditworthiness, and executes this Agreement at Borrower's request and not at the request of Lender;

---

c.	That Grantor has established adequate means of obtaining from Borrower on a continuing basis information about Borrower's financial condition;

j.

That Grantor shall promptly pay or cause to be paid when due all statements and charges of airport authorities, mechanics, laborers, materialmen, suppliers and others incurred in connection with the use, operation, storage, maintenance and repair of the Collateral so that no Encumbrance may attach to or be filed against the Collateral, and shall obtain, upon request by Lender, and in form and substance as may then be satisfactory to Lender, appropriate waivers and/or subordinations of any Encumbrances that may affect the Collateral at any time;

k.	That unless waived by Lender all proceeds from any disposition of the Collateral (for whatever reason) shall be held in trust for Lender and immediately delivered to Lender, and shall not be commingled with any other funds; provided however, this requirement shall not constitute consent by Lender to any sale or other disposition;

6.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower’s accounts with Lender (whether checking, savings, or some other account, and whether held separately or jointly). Grantor authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the Indebtedness against any and all such accounts, and, at Lender's option, to administratively freeze all such accounts to allow Lender to protect Lender's charge and setoff rights provided in this paragraph.

Except for routine use or a part-out and sale of any of the Collateral under paragraph 4.g. hereof, Grantor shall not remove the Collateral from its existing location without Lender's prior written consent. Grantor shall, whenever requested, advise Lender of the exact location of the Collateral. At any reasonable time, on demand by Lender, Grantor shall cause the Collateral (including the logs, books, manuals, and records concerning the Collateral) to be exhibited to Lender (or persons designated by Lender) for purposes of inspection and copying subject to the provisions of the applicable Lease, if any.

TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes, assessments and liens upon the Collateral, its use or operation, upon this Agreement, upon the Note, or upon any of the other Loan Documents. Grantor may withhold any such payment or may elect to contest any lien if Grantor is in good faith conducting an appropriate proceeding to contest the obligation to pay and so long as Lender’s interest in the Collateral is not jeopardized in Lender’s sole opinion. If the Collateral is subjected to a lien which is not discharged within fifteen (15) days, Grantor shall deposit with Lender cash, a sufficient corporate surety bond or other security satisfactory to Lender in an amount adequate to provide for the discharge of the lien plus any interest, costs or other charges that could accrue as a result of foreclosure or sale of the Collateral.

---

15.	INSURANCE.

a.

Grantor shall procure and maintain at all times all risks insurance on the Collateral, including, without limitation, fire, theft, liability and hull insurance, and such other insurance as Lender may require with respect to the Collateral, in form, amounts, coverages and basis reasonably acceptable to Lender and issued by a company or companies reasonably acceptable to Lender. Grantor shall further provide and maintain, at its sole cost and expense (provided, that Grantor may cause such insurance costs to be paid or reimbursed by any permitted lessee), comprehensive public liability insurance, naming both Grantor and Lender as parties insured, protecting against claims for bodily injury, death and/or property damage arising out of the use, ownership, possession, operation and condition of the Collateral, and further containing a broad form contractual liability endorsement covering Grantor's obligations to indemnify Lender as provided under this Agreement. Such policies of insurance must also contain a provision, in form and substance acceptable to Lender, prohibiting cancellation or the alteration of such insurance without at least ten (10) days prior written notice to Lender of such intended cancellation or alteration. Such insurance policies also shall include an endorsement providing that coverage in favor of Lender will not be impaired in any way by any act, omission or default of Grantor or any other person. Grantor agrees to provide Lender with copies of such policies of insurance. Grantor, upon request of Lender, will deliver to Lender from time to time the policies or certificates of insurance in form satisfactory to Lender. In connection with all policies covering assets in which Lender holds or is offered a security interest for the Indebtedness, Grantor will provide Lender with such lender's loss payable or other endorsements as Lender may require. Grantor shall not use or permit the Collateral to be used in any manner or for any purpose excepted from or contrary to the requirements of any insurance policy or policies required to be carried and maintained under this Agreement or for any purpose excepted or exempted from or contrary to the insurance policies, nor shall Grantor do any other act or permit anything to be done which could reasonably be expected to invalidate or limit any such insurance policy or policies.

---

b.

Grantor shall promptly notify Lender of any loss or damage to the Collateral, whether or not such casualty or loss is covered by insurance. Lender may make proof of loss if Grantor fails to do so within fifteen (15) days of the casualty. All proceeds of any insurance on the Collateral, including accrued proceeds thereon, shall be held by Lender as part of the Collateral. If Lender consents to repair or replacement of the damaged or destroyed Collateral, Lender shall, upon satisfactory proof of expenditure, pay or reimburse Grantor from the proceeds for the reasonable cost of repair or restoration. If Lender does not consent to repair or replacement of the Collateral, Lender shall retain a sufficient amount of the proceeds to pay all of the Indebtedness, and shall pay the balance to Grantor. Any proceeds which have not been disbursed within six (6) months after their receipt and which Grantor has not committed to the repair or restoration of the Collateral shall be used to prepay the Indebtedness.

c.

Grantor, upon request of Lender, shall furnish to Lender reports on each existing policy of insurance showing such information as Lender may reasonably request including the following: (1) the name of the insurer; (2) the risks insured; (3) the amount of the policy; (4) the property insured; (5) the then current value on the basis of which insurance has been obtained and the manner of determining that value; and (6) the expiration date of the policy.

16.

PRIOR ENCUMBRANCES. To the extent applicable, Grantor shall fully and timely perform any and all of Grantor’s obligations under any prior Encumbrances affecting the Collateral. Without limiting the foregoing, Grantor shall not commit or permit to exist any breach of or default under any such prior Encumbrances. Grantor shall further promptly notify Lender in writing upon the occurrence of any event or circumstances that would, or that might, result in a breach of or default under any such prior Encumbrance. Grantor shall further not modify or extend any of the terms of any prior Encumbrance or any Indebtedness secured thereby, or request or obtain any additional loans or other extensions of credit from any third party creditor or creditors whenever such additional loan advances or other extensions of credit may be directly or indirectly secured, whether by cross-collateralization or otherwise, by the Collateral, or any part or parts thereof, with possible preference and priority over the lien of this Agreement.

17.

NOTICE OF ENCUMBRANCES AND EVENTS OF DEFAULT. Grantor shall immediately notify Lender in writing upon the filing of any attachment, lien, judicial process, or claim relating to the Collateral. Grantor additionally agrees to immediately notify Lender in writing upon the occurrence of any Event of Default, or event that with the passage of time, failure to cure, or giving of notice, may result in an Event of Default under any of the Grantor’s obligations that may be secured by any presently existing or future Encumbrance, or that may result in an Encumbrance affecting the Collateral, or should the Collateral be

---

18.

GRANTOR'S RIGHT TO POSSESSION. Until a Default has occurred and is continuing under this Agreement or the Loan Documents, Grantor shall have the right to possession and beneficial use of the Collateral and may use it in any lawful manner not inconsistent with this Agreement or the Loan Documents. Lender agrees not to disturb or otherwise interfere with the quiet enjoyment by Lessee of the Collateral so long as no default shall have occurred and is continuing under the Lease.

19.

LENDER'S EXPENDITURES. If any action or proceeding is commenced that would materially affect Lender’s interest in the Collateral or if Grantor falls to comply with any provision of this Agreement or any Loan Documents, including but not limited to Grantor’s failure to discharge or pay when due any amounts Grantor is required to discharge or pay under this Agreement or any Loan Documents, Lender on Grantor’s behalf may (but shall not be obligated to) take any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on the Collateral and paying all costs for insuring, maintaining and preserving the Collateral. All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Grantor. All such expenses will become a part of the Indebtedness and, at Lender’s option, will (A) be payable on demand; (B) be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either (1) the term of any applicable insurance policy; or (2) the remaining term of the Note; or (C) be treated as a balloon payment which will be due and payable at the Note's maturity. The Agreement also will secure payment of these amounts. Such right shall be in addition to all other rights and remedies to which Lender may be entitled upon Default.

20.	DEFAULT. Each of the following shall constitute an Event of Default under this Agreement:

a.	Payment Default. Borrower fails to make any payment within three (3) Business Days after such payment is due under the Indebtedness.

b.	Other Defaults. Borrower or Grantor fails to comply with or to perform any other term, obligation, covenant or condition contained in this Agreement or in any of the Loan Documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower or Grantor.

c.	False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or Grantor, or on Borrower's or Grantor’s behalf under this Agreement or the Loan Documents is false or misleading in any material respect when made.

---

d.

Death or Insolvency. The dissolution of a Borrower or Grantor (whether voluntary or involuntary), or any other termination of a Borrower's or Grantor’s existence as a going business concern; or any equity holder withdraws from a Borrower or Grantor, dies or its existence is terminated and the applicable Borrower or Grantor does not obtain a substitute equity holder approved by Lender within one hundred twenty (120) days following such withdrawal, death or termination, and Lender's approval shall not be unreasonably withheld; or the insolvency of a Borrower or Grantor, including without limitation, the appointment of a receiver for any part of a Borrower's or Grantor’s property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws (whether voluntary or involuntary).

e.	Defective Collateralization. This Agreement or any of the Loan Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time and for any reason, or any Collateral is or becomes subject to any liens other than liens disclosed to and expressly permitted by Lender.

f.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or Grantor or by any governmental agency against any collateral securing the Indebtedness. This includes a garnishment of any of Borrower's or Grantor’s accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower or Grantor as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower or Grantor gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

g.

Events Affecting Guarantors. Any of the preceding events occurs with respect to any Guarantor (as such Guarantors are identified in the Master Loan Agreement) of the Indebtedness or a Guarantor dies or becomes incompetent or revokes or disputes the validity of or liability under any Guaranty of the Indebtedness. Notwithstanding anything to the contrary herein, or in any of the Loan Documents, the death or incompetency of a Guarantor shall not be an Event of Default if, within one hundred twenty (120) days following such death, the Borrowers provide a substitute guarantor approved by Lender, and Lender’s approval shall not be unreasonably withheld. Notwithstanding anything else in this Agreement or any Loan Document, or in any of the documents related hereto, neither a breach by a Guarantor of any agreement between the Guarantor and Lender, other than a Guaranty Agreement, nor the failure of a Guarantor to comply with or to perform any term, obligation, covenant, or condition contained in any agreement between the Guarantor and Lender, other than a Guaranty Agreement, shall constitute an Event of Default.

---

h.	Change in Control of Operations. Joe Kuhn and Miriam Cohen-Kuhn cease to oversee the day to day operations of Borrower or Grantor.

21.

CURE PROVISIONS. If any default, other than a default in payment, is curable and if Grantor has not been given a notice of a breach of the same provision of this Agreement within the preceding twelve (12) months, it may be cured if Grantor, after Lender sends written notice to Borrower demanding cure of such default: (1) cures the default within fifteen (15) days; or (2) if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender’s sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

22.	RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this Agreement, at any time thereafter, Lender shall have all the rights of a secured party under the Wisconsin Uniform Commercial Code. In addition and without limitation, Lender may exercise any one or more of the following rights and remedies:

a.	Accelerate Indebtedness. Lender may declare the entire Indebtedness, including any prepayment penalty which Borrower would be required to pay, immediately due and payable, without notice of any kind to Borrower or Grantor.

b.

Assemble Collateral. Lender may require Grantor to deliver to Lender all or any portion of the Collateral and any and all certificates of title and other documents relating to the Collateral. Lender may require Grantor to assemble the Collateral and make it available to Lender at a place to be designated by Lender. Lender also shall have full power to enter upon the property of Grantor to take possession of and remove the Collateral. If the Collateral contains other goods not covered by this Agreement at the time of repossession, Grantor agrees Lender may take such other goods, provided that Lender makes reasonable efforts to return them to Grantor after repossession.

c.

Sell the Collateral. Lender shall have full power to sell, lease, transfer, or otherwise deal with the Collateral or proceeds thereof in Lender's own name or that of Grantor. Lender may sell the Collateral at public auction or private sale. Unless the Collateral threatens to decline speedily In value or is of a type customarily sold on a recognized market, Lender will give Grantor, and other persons as required by law, reasonable notice of the time and place of any public sale, or the time after which any private sale or any other disposition of the Collateral is to be made. However, no notice need be provided to any person who, after Event of Default occurs, enters into and authenticates an agreement waiving that person's right to notification of sale. The requirements of reasonable notice shall be met if such notice is given at least ten (10) days before the time of the sale or disposition. All expenses relating to the disposition of the Collateral including without limitation the expenses of retaking, holding, insuring, preparing for sale and selling the Collateral, shall become a part of the Indebtedness secured by this Agreement and shall be payable on demand, with interest at the Note rate from date of expenditure until repaid.

---

d.

Appoint Receiver. Lender shall have the right to have a receiver appointed to take possession of all or any part of the Collateral, with the power to protect and preserve the Collateral, to operate the Collateral preceding foreclosure or sale, and to collect the rents from the Collateral and apply the proceeds, over and above the cost of the receivership, against the Indebtedness or as the court may direct. The receiver may serve without bond if permitted by law. Lender's right to the appointment of a receiver shall exist whether or not the apparent value of the Collateral exceeds the Indebtedness by a substantial amount.

Election of Remedies. Except as may be prohibited by applicable law, all of Lender's rights and remedies, whether evidenced by this Agreement, the Loan Documents, or by any other writing, shall be cumulative and may be exercised singularly or concurrently.
