1. LEASED PREMISES, BUILDING, PROPERTY, COMMON AREAS, AND TERM. This Lease Agreement is made and entered into by and between GREYSTONE PROPERTIES, LLC an OKLAHOMA Corporation ("Landlord") and GREYSTONE MANUFACTURING, LLC an OKLAHOMA Corporation ("Tenant"). The Landlord does hereby demise and lease unto the Tenant approximately 60,000 square feet of space which is the property known as RIVERSIDE INDUSTRIAL PARK, said space which is located at 2600 SHORELINE DRIVE, BETTENDORF, IOWA (hereinafter referred to as the "Leased Premises"). The building in which the Leased Premises is situated (hereinafter referred to as the "Building") comprises a portion of the property that is legally described in the attached Exhibit A ("Property"). In addition to the Building and the land upon which the Building is situated, the Property also includes parking areas, loading areas and roadways ("Common Areas"). The Term of this Lease shall be for a period of TEN (10) YEARS, commencing on JULY 1, 2004 OR UPON CLOSING OF THE SALE OF THE PROPERTY, excepting delays due to strikes, acts of God, failure in delivery of materials and events beyond Landlord's control, and ending 120 MONTHS LATER, unless said Term shall be terminated sooner as hereinafter provided.

2. BASE RENT AND SECURITY DEPOSIT.

(a) In consideration of said Lease, the Tenant, without prior notice or demand, agrees to pay to the Landlord on a monthly basis a Base Rent for said Leased Premises for the term of the Lease as follows:

FROM 11/01/04 TO 06/30/14 $25,000.00 PER MONTH

In addition, Tenant shall also be responsible for payment of personal property taxes and Rent taxes, if any. For the purpose of this Lease, the term ("Rent") shall include all Base Rent and any Additional Rent owed by Tenant to Landlord as provided for herein. Said Rent shall be due and payable in advance on the first day of each month during the Term of this Lease at the office of the Landlord's Management Agent, or such other place as the Landlord from time to time, in writing, may designate. Rent not received on or before the tenth (10th) day of each month during the Term of this Lease shall be considered delinquent and subject to the Late Charges as enumerated in Paragraph 3 of this Lease. With the execution of this Lease, Tenant has deposited with the Landlord the sum of $25,000.00.

(b) Security Deposit is defined as monies pledged as security for the payment of Rent and other charges herein agreed to be paid, and for the faithful performance of all the terms, conditions, and covenants of this Lease. If at any time during the term of this Lease, Tenant shall be in default in performance of any provision of this

Lease, and shall fail to remedy or cure said default after having received ten (10) days written Notice of same, then the Landlord may, at its option, apply monies held as partial or full satisfaction of said default or declare said Security Deposit to be forfeited. If Landlord applies all or a portion of Tenant's Security Deposit to cure said default, Tenant agrees to pay to Landlord within ten (10) days of said Notice an equal amount so that the Landlord has at all times a Security Deposit equal to the original amount herein agreed to. Tenant's failure to do so constitutes a default of this Lease. Within sixty (60) days after the Tenant's satisfactory completion of this Lease, Landlord shall refund the Tenant's Security Deposit in full and without interest.

(c) No dispute between the Landlord and the Tenant as to Landlord or Tenant obligations under this Lease shall excuse payment of Rent or the faithful performance of any other conditions of this Lease by either Party.

3. LATE CHARGE. Tenant acknowledges that late payment to Landlord of Rent or other sums due hereunder will cause Landlord to incur costs not contemplated by this Lease. the exact amount of which would be extremely difficult and impractical to ascertain. Such costs include, but are not limited to, processing and accounting charges, and late charges that may be imposed on Landlord by the terms of any mortgage or trust deed covering the Property. Therefore, in the event Tenant should fail to pay any installment of Rent or any sum due hereunder after such amount is due, Tenant shall, upon demand, pay to Landlord as Additional Rent, a late charge equal to 10% of each such installment or other sum due and payable, or $50.00 per day said installment of Rent or sum due hereunder is past due, whichever is greater. Said late charge shall be assessed on the 11th day of each month. Tenant shall be assessed a $25.00 charge for each check that is returned due to insufficient funds in the Tenant's account.

4. PROPERTY OPERATING EXPENSES.

(a) REAL PROPERTY TAXES AND PROPERTY INSURANCE PREMIUMS: Tenant agrees to pay to the Landlord as Additional Rent its pro rata share of the estimated real property taxes and property insurance premiums incurred during each calendar year. Said payment shall be made in advance to the Landlord, in monthly installments and due and payable on the first day of each month during the term of this Lease. As used in this paragraph, ("real property tax") shall mean any form of assessment (both general and special), levy, penalty, or tax (other than estate or inheritance tax) imposed by any authority having direct or indirect power to tax any legal or equitable interest of Landlord in the Property, including any tax on rent (other than income tax) in lieu of, or in addition to normal real property taxes or assessment.

In the event Landlord makes an investment for improvements to the Property which has the effect of reducing operating costs, these expenditures will be amortized over the asset's useful life as determined by the Landlord and such amortization shall be included as an additional component of Operating Costs.

(c) PROPERTY OPERATING EXPENSES: Real Property Taxes, Property Insurance Premiums, and Operating Costs ("Property Operating Expenses") associated with the operation of the Property are currently estimated to be $1.20 PER SQUARE FOOT.

The Tenant shall not, without the written consent of Landlord, connect with electric current, except through existing electrical outlets in the Leased Premises. If Tenant shall require water, gas, or electric current in excess of that normally supplied for use of the Leased Premises as general office/warehouse space, Tenant shall first obtain the written consent of the Landlord, which Landlord shall not unreasonably refuse to grant. Any additional expense in monitoring the water, gas, and electric current consumed will be paid for by the Tenant.

(2) Enter the Leased Premises without terminating the Lease and perform the Tenant's obligations per the terms of this Lease. The Tenant agrees to reimburse the Landlord on demand for all expenses incurred by the Landlord in performing the Tenant's obligations under this Lease, including the amount of Rent due and payable by the Tenant per the terms of this Lease;

The Landlord shall receive the rents for such reletting and shall apply the same as follows: first, to the payment of any indebtedness other than rent due hereunder from Tenant to Landlord; second, to the payment of such expenses as Landlord may have incurred in connection with reentering, ejecting, removing, dispossessing, reletting, altering, repairing, redecorating, sub-dividing, or otherwise preparing the Leased Premises for reletting, including brokerage and

The Tenant shall be and hereby agrees to be liable for and to pay to the Landlord any deficiency arising between the rents, additional rents and other charges due and payable per this Lease and the net rentals received by the Landlord due to the reletting the Leased Premises. The deficiency shall be for each month of the period which otherwise would have constituted the balance of the Lease term. The Tenant hereby agrees to pay such deficiency to the Landlord in monthly installments on the rent day specified in this Lease.

(c) Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the other remedies herein provided or any other remedies provided by law, nor shall pursuit of any remedy herein provided constitute a forfeiture or waiver of any Rent due to Landlord hereunder or of any damages accruing to Landlord by reason of the violation of any of the terms, provisions, and covenants herein contained. No waiver by the Landlord of any violation or breach of any terms, provisions or covenants herein contained shall be deemed or construed to constitute a waiver of any other violation or breach. Upon an event of default by the Tenant, forbearance by the Landlord to enforce one or more of the remedies herein provided shall not be deemed or construed to constitute a waiver of such default.

(d) The Tenant acknowledges and agrees that should it become necessary for the Landlord to serve a notice for the demand for the payment of Rent or a notice for possession of the Leased Premises ("Notice") in accordance with applicable state statutes, the Notice shall not terminate the Tenant's obligations to pay future Rents and this Lease, at the sole option of the Landlord, may continue in full force and effect;

If Tenant abandons or vacates any portion of the Property, or is in default of the payment of any Rent, damage, or other payments as required herein, Landlord may enter upon the Leased Premises, by force if necessary, and take possession of all or part of the aforesaid items. Landlord may sell all or part of the aforesaid items at a public or private sale, in one or successive sales, with or without Notice, to the highest bidder for cash. In addition, Landlord may, on behalf of Tenant, sell and convey all or part of aforesaid items to the bidder, and deliver to the bidder all of the Tenant's title and interest in said items. The proceeds of the sale shall be applied by the Landlord toward the cost of the sale and then toward the payment of all sums then due by Tenant to Landlord under the terms of this Lease. The statutory lien for Rent is not hereby waived, the express contractual lien herein granted being in addition and supplementary thereto, to the extent, if any, this Lease grants Landlord or recognizes in Landlord any lien or lien rights greater than provided by the laws of the state in which the Property is located. At Landlord's option, this Lease may be intended as a security agreement within the meaning of the Uniform Commercial Code. Landlord, in addition to the rights prescribed in this Lease, shall have all the rights, titles, liens, and interests in and to Tenant's property now or hereafter located upon the Leased Premises which are granted a secured party, as that term is defined under the Uniform Commercial Code, to secure the payment to Landlord of the various amounts provided for in this Lease and in compliance with same.

8. COSTS AND ATTORNEY'S FEES. If it becomes necessary for either the Landlord or Tenant to employ an attorney due to the default or breach of a provision of this Lease, to gain possession of the Leased Premises, or to further protect its interest as granted per the terms and provisions herein contained, the non-prevailing party shall pay, in addition to its own costs and expenses, a reasonable attorney's fee and all costs and expenses expended or incurred by the prevailing party in connection with such default or action.

9. ALTERATIONS TO THE LEASED PREMISES, BUILDING, PROPERTY AND COMMON AREAS.

(a) To Leased Premises. Tenant shall not make any alterations, additions, or improvements to the Leased Premises without the prior written consent of Landlord, which shall not be unreasonably withheld or delayed. Tenant may, at its own cost and expense, make such minor alterations such as shelves, bins, and trade fixtures as it may deem advisable, without altering the basic character of the Property or Leased Premises, provided it is accomplished in a good, workmanlike

manner. In such cases, Tenant agrees to comply with all of the applicable governmental laws, ordinances, regulations, and any other requirements including, but not limited to, the application for building permits, request for inspections, etc. Tenant shall promptly pay for the costs of all work performed and shall indemnify and hold harmless the Landlord against liens, costs, damages, or expenses incurred in connection therewith, including attorney's fees, incurred by the Landlord if Landlord shall be joined in any action or proceeding involving such work. Under no circumstances shall Tenant commence any such work until Landlord has been provided with evidence that the contractor is licensed to do the desired repairs in the state in which the Leased Premises is situated, that the contractor carries adequate worker's compensation as required by the laws of the state in which the Leased Premises is situated, that the contractor is adequately bonded and that the contractor carries public liability and builder's risk insurance in amounts deemed satisfactory by the Landlord.

Upon Lease termination, Tenant shall remove all alterations, additions, improvements, shelves, bins, equipment, and trade fixtures and partitions erected by Tenant and restore the Leased Premises to its original condition, wear and tear excepted, if so desired by Landlord; otherwise, such improvements shall become a part of the Leased Premises and shall be delivered to the Landlord along with the Leased Premises upon Lease termination. Any such removals and restorations shall be accomplished in a workmanlike manner so as not to damage the primary structure or structural qualities of the Leased Premises, the Property, the Common Areas or any other improvements situated on the Property.

(b) To Building, Common Areas and Property. Landlord reserves the right to change from time to time the dimensions and location of the Common Areas, as well as the dimensions, identity, and type of any building situated on the Property, including constructing a new building(s) on and/or removing an existing building(s) from the Property. Landlord shall also be permitted to make changes to the Building, unless doing so would reasonably interfere with the Tenant's use of the Leased Premises, in which case the Landlord must first reach agreement with the Tenant about those changes that are to be made to the Building prior to commencing work on any such changes to the Building. Landlord also reserves the right to dedicate portions of the Common Areas for streets, parks, utilities, and other public purposes as well as to utilize portions thereof for other such uses as the Landlord may from time to time deem profitable or desirable, provided that in doing so does not unreasonably interfere with the Tenant's use thereof. The Common Areas shall be subject to rules and regulations as Landlord deems reasonable and appropriate. Landlord reserves the right to designate specific areas in which vehicles owned by the Tenant, its employees, sublessee(s), concessionaires, and licensees shall be parked. Upon Landlord's request, the Tenant agrees to furnish to Landlord a complete list of the license numbers of all vehicles operated by the Tenant. The Landlord reserves the right to temporarily close any part of the Common Areas for such periods of time as may be necessary to prevent the public from obtaining prescriptive rights thereto or to make repairs

or alterations. The Tenant shall not take any action that would interfere with the rights of the Landlord or of any other tenants of the Property, including their respective employees, agents, contractors, vendors or invitees.

10. SIGNS, WINDOW COVERINGS. No sign, placard, picture, advertisement, name, notice, lettering, door sign, window covering, awning, or other projection ("Signage") visible from the exterior of the Leased Premises shall be exhibited, inscribed, painted, or otherwise displayed by the Tenant on any part of the inside or outside of the Leased Premises, including all windows and doors which comprise a portion of the Leased Premises, or on any building(s) situated upon the Property without first obtaining the consent of the Landlord. If the Landlord shall have given said consent, whether before or after the execution of this Lease, said consent shall in no way operate as a waiver or release of any of the provisions of this Lease and shall be deemed to relate only to that particular Signage consented to by the Landlord and shall not be construed as dispensing with the necessity of obtaining the specified written consent of the Landlord with respect to any other such Signage. Tenant shall remove all Signage at the termination of this Lease. Signage installation and removal shall be made in such a manner as to avoid injury, defacement, or overloading the Building and any other improvements thereto. Drawings for all Tenant identification Signage shall be approved by Landlord before the manufacture and installation thereof. The cost and installation of all Signage shall be at the sole expense of the Tenant.

11. MECHANIC'S LIENS. Tenant agrees that it will not permit any mechanic's liens to attach to the Property.

12. CHARACTER OF OCCUPANCY. The Leased Premises shall be used exclusively for MANUFACTURING, WAREHOUSE AND OFFICE USE. Tenant shall at its own cost and expense obtain any and all licenses and permits necessary for such use. Tenant shall comply with all governmental laws, ordinances, and regulations applicable to the use of the Leased Premises. The Tenant, at its own cost and expense, shall comply with all laws, rules, and regulations applicable to the peculiar nature of the Tenant's use of the Leased Premises. The Tenant's obligation to comply with laws, rules, and regulations applicable to the peculiar nature of the Leased Premises shall include the obligation to locate furniture and fixtures in accordance with the Americans With Disabilities Act (A.D.A.) and the rules and regulations adopted thereunder. The Tenant shall promptly comply with all Landlord or governmental orders and directives for the correction, prevention, and abatement of nuisances in or upon, or connected with the Leased Premises, all at Tenant's sole expense. Tenant agrees to pay, on demand, costs for any damage or repairs to the Leased Premises or Property caused by the misuse of same by the Tenant, its agents, or employees. Tenant shall not permit the Leased Premises to be used in any way which would, in the opinion of the Landlord, be extra hazardous or which would in any way increase the insurance premiums upon the Property or cause the cancellation of any insurance policy covering the Leased Premises or the Property, nor shall Tenant sell or permit to be kept, used, or sold in or about the Leased Premises any articles which may be prohibited by a standard form policy of fire or other hazard insurance. If Tenant's use of the Leased Premises results in any increase in premiums for

insurance, Tenant will promptly reimburse Landlord for the cost of such increase. Tenant's acts which might result in insurance premium increases include, without limiting the generality of the foregoing, such things as storing or using flammable substances, stocking materials too close to the ceiling or sprinklers, failure to maintain adequate aisles, or failure to impose or enforce smoking rules. Any conduct of Tenant which causes an increase in fire or other hazard insurance premiums, or which is in violation of recommendations by Landlord's insurance carrier, or failure by Tenant to promptly take any corrective action recommended by Landlord's insurance carrier shall be a material default under this Lease and Landlord shall be entitled to all of the remedies in Paragraph Six of this Lease.

Tenant shall not use the Leased Premises or permit anything to be done in or about the Leased Premises which will in any way conflict with any law, statute, zoning restriction, ordinance or governmental rule or regulation or requirement of duly constituted public authorities now in force or which may hereafter be enacted or promulgated. Tenant shall, at its sole cost and expense, promptly comply with all applicable laws, statutes, ordinances, and governmental rules, regulations, or requirements now in force or which may hereafter be in force, and with the requirements of any board of fire underwriters or other similar body now or hereafter constituted relating to or affecting the condition, use or occupancy of the Leased Premises. The judgment of any court of competent jurisdiction or the admission of Tenant in any action against Tenant, whether Landlord be a party thereto or not, that Tenant has violated any law, statute, ordinance or governmental rule, regulation or requirement, shall be conclusive of that fact as between Landlord and Tenant.

This Paragraph applies particularly and specifically, without limiting the generality thereof, to any act that is in violation of that body of law generally referred to as The Hazardous Substances Law. At the time this Lease is made, such body of law includes, but is not limited to, the Atomic Energy Act, the Clean Air Act, the Comprehensive Environmental Response Compensation and Liability Act of 1980 (known as "Superfund"), the Clean Water Act, the Federal Insecticide, Fungicide and Rodenticide Act, the Occupational Safety and Health Act, the Resource Conservation and Recovery Act of 1976 (Amended), the Solid Waste Disposal Act, the Toxic Substances Control Act, and the Used Oil Recycling Act. Tenant will indemnify Landlord against all cost, expense, or loss, including attorney's fees, which Landlord may sustain as a result of Tenant's violation of its obligations under this Paragraph. Any violation by Tenant of its duties contained herein shall be a material default under this Lease that will entitle Landlord to all of its remedies under this Lease. All obligations of Tenant shall survive termination of this Lease.

13. POSSESSION.

(a) If Landlord cannot deliver possession of the Leased Premises to the Tenant upon the commencement of the term hereof, this Lease shall not be void or voidable, nor shall Landlord be liable to Tenant for any loss or damage resulting therefrom. The term of the Lease shall be amended to commence on the date when Landlord

can deliver possession of the Leased Premises to the Tenant and the expiration date shall be extended accordingly. If permission is given to Tenant to occupy the Lease Premises prior to the commencement date of the Lease, such occupancy shall be subject to all provisions of this Lease and the Rent shall be prorated to the date of the Tenant's occupancy of the Leased Premises. If the term hereof commences on the date later than said commencement date pursuant to the provisions set forth above, Landlord and Tenant agree to execute and acknowledge a written statement setting forth the actual commencement date and termination date of this Lease. This Lease shall be in full force and effect even though either Landlord or Tenant may fail or refuse to execute such Statement.

(b) The taking of possession of the Leased Premises by the Tenant shall be conclusive evidence that said Leased Premises was in good and satisfactory condition when possession of same was taken.

14. LEASE ASSIGNMENT OR SUBLETTING.

(a) Landlord's Consent Required. Tenant shall not have the right to assign, sell, encumber, pledge, sublease, or otherwise transfer all or any part of Tenant's leasehold estate herein (any of the preceding constituting a "Transfer"), or permit the Leased Premises to be occupied by anyone other than the Tenant or its employees, or to sublet the Leased Premises or any portion thereof without first obtaining prior written consent of Landlord. Consent by Landlord to one or more Transfers shall not be deemed to be a consent to any subsequent Transfer. The Tenant shall not change the ownership of the business in order to avoid this provision, and will, at the request of the Landlord, provide whatever documentation is necessary to establish that the Tenant is in compliance with this provision.

(b) Tenant's Request For Landlord Consent. If Tenant desires at any time during the term of this Lease to Transfer its interest, or any portion thereof, it shall first notify Landlord of its desire to do so and shall submit to the Landlord in writing the name and address of the proposed assignee, the nature of the proposed assignee's work or business to be conducted at the Leased Premises, the proposed sublease, assignment, and other Transfer documentation, all in reasonable detail as Landlord may request, along with a non-refundable processing fee equal to the greater of one thousand five hundred dollars ($1,500.00) or one-half (1/2) of the then monthly Base Rent. In addition, Tenant agrees to reimburse Landlord for all legal fees and other expenses associated with any proposed Transfer.

(c) Landlord's Rights. At any time within thirty (30) days after Landlord is in receipt of the above-referenced items, Landlord may by written notice to Tenant elect to consent to the Transfer of the Lease upon the terms and to the assignee as proposed, refuse to give its consent to the proposed Transfer, terminate this Lease and enter directly into a new lease with the proposed assignee, or terminate this Lease effective as of the date such proposed Transfer would have become

effective. If the Landlord allows Tenant to Transfer its Lease or to sublet the Leased Premises, then in the event of default as herein defined, Landlord may collect all Rent and other sums due hereunder directly from such assignee or subtenant and apply said Rent against any sums due the Landlord by the Tenant hereunder. Tenant or any other assignor or sublessor may not collect Rent in excess of the existing Lease rates and any such sums received by the Tenant or other assignor or sublessor must be immediately paid to the Landlord. The Landlord shall also have the right to assign any of its rights under this Lease.

(d) No Release of Liability. No Transfer, even with the consent of Landlord, shall relieve Tenant of its obligations to pay Rent and to perform all other obligations to be performed by Tenant under this Lease. The acceptance by Landlord of any payment due hereunder from any other person shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer.

15. INSURANCE, LIABILITY, INDEMNITY AND WAIVER OF SUBROGATION.

(a) Insurance and Liability. Tenant shall throughout the Lease Term, at its sole cost and expense, provide and keep in force with responsible insurance companies satisfactory to Landlord and to any mortgagee under a mortgage constituting a lien upon the Property, public liability and property damage insurance.

Tenant shall furnish Landlord a Certificate of Insurance prior to the commencement of this Lease naming Landlord as an additional insured. Tenant shall also furnish Landlord's Management Agent a Certificate of Insurance prior to the commencement of this Lease naming Landlord's Management Agent as an additional insured. Landlord, at its sole option, may procure and maintain at times during the term of this Lease a policy or policies of insurance covering loss or damage to the Property (exclusive of Tenant's trade fixtures, equipment, and personal property), providing protection against those perils as Landlord deems appropriate.

(b) Indemnity.

(1) Tenant hereby agrees to defend, pay, indemnify, and save free and harmless Landlord, from and against any and all claims, demands, fines, suits, actions, proceedings, orders, decrees, and judgments of any kind or nature by or in favor of anyone whomsoever and from and against any and all costs and expenses, including reasonable attorney's fees, resulting from or in connection with loss of life, bodily or personal injury or property damage arising, directly or indirectly, out of or from or on account of any occurrence in, upon at or from the Leased Premises or occasioned wholly or

in part through the use and occupancy of the Leased Premises or any improvements therein or appurtenances thereto, or by any act or omission or negligence of Tenant, or any subtenant, concessionaire, or licensee of Tenant or their respective employees, agents, or contractors in, upon, at or from the Leased Premises, or its appurtenances.

(2) Tenant and all those claiming by, through or under Tenant shall store their property in and shall occupy and use the Leased Premises and any improvements therein and appurtenances thereto, solely at their own risk and hereby release Landlord to the full extent permitted by law, from all claims of every kind, including loss of life, personal, or bodily injury, damage to merchandise, equipment, fixtures, or other property, or damage to business or for business interruption, arising, directly or indirectly, out of or from or on account of such occupancy and use or resulting from any present or future condition, state of repair thereof.

(3) Landlord shall not be responsible or liable for damages at any time to Tenant, or those claiming by, through or under Tenant, for any loss of life, bodily, or personal injury, or damage to property or business, or for business interruption that may be occasioned by or through the acts, omissions or negligence of any other person.

(4) Landlord shall not be responsible or liable for damages at any time for defects, latent or otherwise, in any building(s), in any improvements within the Leased Premises or in any of the equipment, machinery, utilities, appliances or apparatus therein. Landlord shall not be responsible or liable for damages at any time, for loss of life, or injury or damage to any person or any property or business of Tenant, or those claiming by, through or under Tenant, caused by or resulting from the bursting, breaking, leaking, running, seeping, overflowing or backing up of water, steam, gas, sewage, snow or ice in any part of the Leased Premises or Property or which is caused by, or resulting from, acts of nature or the elements, or resulting from any defect or negligence in the occupancy, construction, operation or use of the Leased Premises or any of the equipment, fixtures, machinery, appliances, or apparatus therein.

(c) Waiver of Subrogation. In the event that any portion of the Property or any portion of the Leased Premises is damaged or destroyed by fire, explosion or other casualty, and to the extent that any such loss is covered by insurance in force and recovery is made for such loss, whether or not such damage or destruction is caused, or claimed to be caused, by the negligence or misconduct of Landlord or Tenant, or any of their respective officers, employees, agents, contractors or invitees, Landlord and Tenant hereby mutually release each other from liability and waive all right of recovery against each other for any loss from perils insured against under their respective fire insurance policies (including extended coverage). Both Landlord and Tenant shall cause its insurance company

to waive all right of recovery by way of subrogation against the other party in connection with any such damage. In addition, during or after Tenant's occupancy of the Leased Premises, Landlord and Tenant shall indemnify and hold each other harmless from any claim made by way of subrogation by either the Landlord's or Tenant's fire and extended coverage insurance carrier(s).

16. DAMAGE OR DESTRUCTION.

(a) In the event improvements to the Leased Premises or the Property are damaged by any casualty which is insured, then Landlord may either repair such damage as soon as is reasonably possible at Landlord's expense, in which event this Lease shall continue in full force and effect, or give written Notice to the Tenant within thirty (30) days after the date of such occurrence of the Landlord's intention to cancel and terminate this Lease. If the Leased Premises is totally destroyed during the term of this Lease from any cause whether or not covered by the insurance required herein, including any destruction required by any authorized public authority, this Lease may automatically terminate, at the option of the Landlord, as of the date of such total destruction.

(b) If the Leased Premises is partially destroyed or damaged and Landlord makes repairs pursuant to this Lease, the Rent payable hereunder for the period during which such damage and repair continues shall be abated in proportion to the extent which Tenant's use of the Leased Premises is impaired. Except for abatement of Rent, if any, Tenant shall have no claim against Landlord for any damage suffered by reason of such damage, destruction, repair, or restoration.

17. EMINENT DOMAIN. If the Property shall be taken by right of eminent domain, in whole or substantially in part, for public purposes, then this Lease, at the option of the Landlord, shall forthwith cease and terminate, and the current Rent shall be properly apportioned to the date of such taking. In such event, Landlord shall receive the entire award for the lands and improvements so taken, and Tenant shall make no claim against Landlord for compensation in connection with said taking.

18. SUBORDINATION. This Lease, and all of the rights of Tenant hereunder, are and shall be subject and subordinate to any sale and/or lien of any mortgage now or hereafter placed on the Property or any part thereof, and to any and all renewals, modifications, consolidations, replacements, extensions, or substitutions of said sale and/or mortgage. Tenant agrees to execute any documents required to effectuate such subordination or to make this Lease subordinate to the lien of any mortgage, deed of trust, or ground lease, as the case may be.

19. ATTORNMENT. If a successor landlord under the sale or the holder of the mortgage shall succeed to the rights of the Landlord under this Lease, whether through possession or foreclosure action or delivery of a new lease or deed, then Tenant, upon the request of such successor landlord, shall attorn to and recognize such successor landlord as Tenant's Landlord under this Lease, and shall promptly execute and deliver any instrument that

such successor landlord may request to further evidence such attornment. Tenant hereby irrevocably appoints Landlord or the successor landlord as attorney-in-fact of Tenant to execute and deliver such instrument on behalf of Tenant, should Tenant refuse or fail to do so promptly after request. Upon such attornment, this Lease shall continue in full force and effect as if it were a direct lease between the successor landlord and Tenant, upon all of the terms, conditions, and covenants as set forth herein.

20. ESTOPPEL CERTIFICATES. The Tenant shall be obligated to duly execute and deliver to the Landlord within seven (7) days after receipt of written notice an Estoppel Certificate that certifies the following information:

(a) that the attached Lease, together with all amendments, modifications, extensions and renewals thereof, comprise a complete copy of the entire Lease Agreement, and that the Lease is presently in full force and effect and has not been otherwise modified or amended, that there are no oral agreements existing as to the terms of the Lease or the use or occupancy of the Leased Premises, that the Lease contains all of the understandings and agreements between the Tenant and Landlord and their predecessors, if any;

(b) the Lease is correctly identified by the date as stated therein;

(c) the commencement date and the expiration date of the Lease

(d) the Tenant does or does not have the right to renew the Lease

(e) the Tenant does or does not have the right to terminate the Lease;

(f) the amount of the monthly Base Rent (not including any percentage rent or expense pass through) presently payable under the Lease and the date through which such Base Rent has been paid;

(g) the amount of the security deposit the Tenant deposited with the Landlord, if any;

(h) that the Landlord is not in default of any terms or conditions of the Lease, the Landlord has observed and performed all of its obligations and has fulfilled all of its warranties and representations, if any, with respect to the Lease and that the Tenant is not asserting any offsets, counterclaims or defenses against the Landlord;

(i) that the Tenant is not in default of any terms or conditions of the Lease;

(j) that the Tenant is in possession of Leased Premises and that the Leased Premises is in conformity with that stated in the Lease;

(k) the Tenant does or does not have an option or a first right of refusal (FRR) to purchase the Property in which the Leased Premises is situated.

(1) the guarantor of the Lease, if any.

(m) the square footage of the Leased Premises, the total square footage of the Property and the Tenant's pro-rata share of the Property;

(n) that the statements contained therein are made for the purpose of verifying the current status of the Tenant's Leasehold interest in Leased Premises and may be relied upon by the Landlord and any successor(s) and/or assignee(s).

At the Landlord's option, the Tenant's failure to deliver such written instrument within the allotted time period shall constitute a material breach of this Lease or shall be conclusive upon the Tenant that: 1) this Lease is in full force and effect, without modification except as may be represented by Landlord; 2) there are no uncured defaults pertaining to Landlord's performance of this Lease; and 3) that the Tenant has not paid in advance more than one (1) month's Base Rent.

21. HOLDING OVER. Should Tenant, or any of its successors-in-interest, hold over the Leased Premises, or any part thereof, after the expiration of the term of this Lease, unless otherwise agreed to in writing by Landlord, such holding over shall constitute and be construed as tenancy from month-to-month only, at a Base Rent equal to 150% of the monthly Base Rent paid during the last month of the Term prior to the holdover.

22. QUIET ENJOYMENT. Landlord warrants that it has full right to execute and to perform this Lease and to grant the estate leases, and, that Tenant, upon payment of the required Rent and performing the terms, conditions, covenants, and agreements contained in this Lease, shall peaceably and quietly have, hold, and enjoy the Leased Premises during the full term of this Lease as well as any extension or renewal thereof. However, Tenant accepts this Lease subject and subordinate to any underlying lease, mortgage, deed of trust, or other lien presently existing upon the Property. Landlord hereby is irrevocably vested with full power and authority to subordinate Tenant's interest under this Lease to any underlying lease, mortgage, deed of trust, or other lien hereafter placed on the Property, and Tenant agrees upon demand to execute additional instruments subordinating this Lease as Landlord may require. If the Landlord's interest under this Lease shall be transferred by reason of foreclosure or other proceedings for enforcement of any lien, deed of trust, or mortgage on the Property, Tenant shall be bound to the transferee (sometimes called "Purchaser") under the terms, covenants, and conditions of this Lease for the balance of the term remaining, and any extensions or renewals thereof, with the same force and effect as if the Purchaser were the Landlord under this Lease. Tenant agrees to attorn to the Purchaser, as its Landlord, the attornment to be effective and self-operative without the execution of any further instruments upon the Purchase succeeding to the interest of the Landlord under this Lease. The respective rights and obligations of Tenant and the Purchaser upon the attornment, to the extent of the then remaining balance of the term of this Lease, and any extensions and renewals thereof, shall be the same as those herein contained.

23. SEVERABILITY CLAUSE. If any clause or provision of this Lease is illegal, invalid, or unenforceable under present or future laws effective during the term of this Lease, it is the intention of Landlord and Tenant that the remainder of this Lease shall not be affected thereby. The caption of each paragraph hereof is added as matter of convenience only and shall be considered to be of no effect in the construction of any provision or provisions of this Lease.

24. SURRENDER OF POSSESSION. The Tenant agrees to deliver, upon the surrender to the Landlord, possession of the Leased Premises, along with all keys thereto, at the expiration or termination of this Lease, by lapse of time or otherwise, in as good repair as when the Tenant obtained the same at the commencement of said term, normal wear and tear excepted, and except damage by the elements (occurring without the fault of the Tenant or other persons permitted by the Tenant to occupy or enter the Leased Premises or any part thereof), or by act of God, or by insurrection, riot, invasion, or of military or usurped power.

25. REMOVAL OF TENANT'S PROPERTY. If the Tenant shall fail to remove all effects from said Leased Premises or Property upon the abandonment thereof, or upon the termination of this Lease for any cause whatsoever, the Landlord, at its option, may remove the same in any manner that it shall choose, and store the said effects without liability to the Tenant for loss thereof. Tenant agrees to pay Landlord on demand for any and all expenses incurred in such removal, including court costs, attorney's fees, and storage charges on such effects. If Landlord is forced to sell any of the same at public or private sale to collect any amounts due under this Lease from Tenant, or simply to dispose of Tenant's effects, the Landlord agrees to render any surplus to Tenant after deducting all costs and expenses associated with such sale.

26. CONSENT NOT UNREASONABLY WITHHELD. Unless otherwise provided, whenever consent or approval of Landlord or Tenant is required under the terms of this Lease, such consent shall not be unreasonably withheld or delayed. Tenant's sole remedy, if Landlord unreasonably withholds or delays consent or approval, shall be an action for specific performance and the Landlord shall not be liable for damages.

27. TENANT FINANCIAL STATEMENTS. Tenant shall furnish to Landlord, upon Landlord's request but not more than once per any given calendar year (except in the event of a sale of the Property, in which case upon the Landlord's request, the Tenant shall furnish to Landlord copies of the Tenant's most current Financial Statements), copies of various financial reports, including but not limited to, a Statement of Income and Expense, a Statement of Financial Position, a Statement of Cash Flows, a Statement of Change in Financial Position, a copy of the Tenant's Federal Income Tax Return and a report enumerating any important information not contained in any of the financial statements ("Tenant Financial Statements").

28. ENTIRE AGREEMENT. Tenant acknowledges and agrees it has not relied upon any agreements, conditions, representations, statements, or warranties except those expressed and contained herein. Tenant acknowledges and agrees that no amendment or

modification of this Lease shall be valid or binding unless expressed in writing and executed by the Landlord and Tenant in the same manner as the execution of this Lease.

29. IMPLIED ACCEPTANCE/SURRENDER.

(a) No act or thing done by Landlord or Landlord's agents during the Term hereof or any extension thereof, shall be deemed an acceptance or a surrender of the Leased Premises, and no agreement to accept such surrender shall be valid unless in writing and signed by Landlord or its designated representative.

(b) The delivery of keys to any employee of the Landlord, or of Landlord's agents, shall not operate as a termination of this Lease or a surrender of the Leased Premises. No partial payment of Rent by Tenant shall be deemed to be other than a payment on account, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction. Landlord may accept any such payment of Rent without prejudice to Landlord's right to recover the balance of any Rent due or pursue any other remedy available to Landlord.

30. FORCE MAJEURE. In the event Landlord or Tenant shall be delayed, hindered, or prevented from the performance of any act required herein by reason of strikes, lockouts, labor troubles, inability to procure materials, failure of power, restrictive governmental laws or regulations, riots, insurrection, war, or any other reason of a like nature ("Event") that is not the fault of the Party delayed in performing the work or doing the acts required under the terms of this Lease, then said performance of any such act shall be excused for the period of time the Event takes place. The period for the performance of any such act shall be extended for a period of time equivalent to the time period of the Event. The provisions of this section shall not operate to excuse Tenant from prompt payment of the Base Rent and any other Rent required by the terms of this Lease.

31. SUCCESSORS. The terms, provisions, covenants, and conditions contained in this Lease shall apply to, inure to the benefit of, and be binding upon the parties, hereto and upon their respective successors in interest and legal representatives except as otherwise herein expressly provided.

32. GENDER. Words of any gender used in this Lease shall be held and construed to include any other gender, and words in the singular number shall be held to include the plural, unless the context otherwise requires.

33. CORPORATE AUTHORITY. If Tenant is a corporation, Tenant warrants that it has legal authority to operate and is authorized to do business in the state in which the Property is situated. Tenant also warrants that the person or persons executing this Lease on behalf of Tenant has authority to do so and to fully obligate Tenant to all terms and provisions of this Lease. Tenant shall, upon request from Landlord, furnish Landlord with a certified copy of resolutions of the Board of Directors authorizing this Lease and

granting authority to execute it to the person or persons who have executed it on Tenant's behalf.

34. NOTICES.
