In such event, Tenant shall pay such estimated amounts monthly in advance in installments equal to one-twelfth (1/12) of the estimate together with Tenant's payment of Base Rent by the first day of each calendar month during the Lease.

Any deficiency or excess payment made by the Tenant when compared to the Tenant's Share of the actual Taxes and Operating Expenses for the previous calendar year shall be credited or debited, as the case may be, to the payments of Rent next due. If the term shall have expired and no further Rent shall be due, Tenant shall receive a refund, or make a payment, of such difference within thirty (30) days after having received such Statement.

Tenant or its representative shall have the right to examine such records upon reasonable prior notice during normal business hours at the place or places where such records are normally kept by Landlord by sending such notice no later that fifteen (15) days following the furnishing of the Statement. Any objection by the Tenant must be communicated to Landlord no later than thirty (30) days after Landlord makes such records available for examination. If Tenant makes exception to any matter contained in the Statement as provided herein and is unable to reach an accord with Landlord regarding such exception, both Tenant and Landlord agree to submit the dispute to arbitration as provided for in Section 11 of this Lease. 2.02(g) BASE RENT, TAXES, OPERATING EXPENSES AND OTHER Base Rent, Taxes, Operating Expenses and any other amounts which Tenant is or becomes obligated to pay Landlord under this Lease, are sometimes herein referred to collectively as "Rent," and all remedies applicable to the non-payment of Rent shall be applicable thereto.

If Tenant is required by the Landlord to make improvements to the Premises, the useful life of which exceeds the remaining term, Tenant shall be responsible only for the cost of such improvements multiplied by a fraction, the numerator of which is the number of years remaining in the term and the denominator of which is the life of the improvement. Tenant shall not make such improvements until Landlord has deposited with Tenant Landlord's share of the costs pursuant to this paragraph 3.01(b). 3.02 Utilities 3.02(a) METER SEPARATION On or before the commencement of the second year of this Lease, Landlord shall ensure that all utilities are separately metered for Tenant's Premises (unless otherwise specifically agreed to between the Landlord and Tenant) and Tenant shall be responsible for paying only those utilities it uses. 3.02(b) GENERAL GROUNDS The Tenant shall be responsible for its pro rata share (in accordance with paragraph 2.02(a) of this Lease) for utilities servicing the general grounds of the property, such as water, sewer and electricity for exterior lighting. However, Landlord expressly agrees to separately meter any and all utilities used in the remediation of the Pre- Existing Environmental Conditions and Landlord further agrees that any and all utility costs associated with such remediation shall be the sole responsibility of the Landlord. 6 3.02(c) INTERRUPTION OF SERVICES Landlord does not warrant that any services Landlord supplies shall not be interrupted. Services may be interrupted because of accidents, repairs, alterations, improvements or for any reason beyond the reasonable control of Landlord. Except as noted below, any interruption shall not: (i) Be considered an eviction or disturbance of Tenant's use and possession of the Premises; (ii) Make Landlord liable to Tenant for damages; (iii) Abate Rent; or (iv) Relieve Tenant from performing Tenant's Lease obligations. If any essential services (such as HVAC, electricity, water) are interrupted and the interruption does not result from the negligence or willful misconduct of Tenant, its employees, invitees or agents, Tenant shall be entitled to an abatement of Rent. The abatement shall begin on the fifth consecutive business day of interruption, or when Tenant stops using the Premises because of the interruption, whichever is later. The abatement shall end when the services are restored. Tenant shall have the option to cancel the Lease if the interruption unreasonably and materially interferes with Tenant's use of, or access to, the Premises for at least thirty (30) consecutive days. To exercise this option, Tenant must give Landlord notice of the cancellation within (30) days from the end of the thirty (30) day period. 3.03 Repairs and Maintenance 3.03(a) TENANT'S CARE OF PREMISES Beginning in month thirteen (13), and subject to the obligations of the Landlord as stated in paragraph 3.03(b) herein, Tenant, at Tenant's expense, shall keep in good order, condition and repair, ordinary wear and tear excepted, including but not limited to, the repair and maintenance of all interior plumbing, mechanical, heating, ventilating and air conditioning systems serving the Premises, electrical and lighting, pipes, ducts, conduits and equipment in, upon or serving the Premises, fixtures, interior walls, interior surfaces of exterior walls, ceiling, windows, doors, glass and skylights in the Premises.

Tenant shall furnish and pay for the upkeep, maintenance and periodic servicing of the heating, ventilating and air conditioning equipment servicing the Premises (unless such equipment is servicing more than the Premises, in which case Tenant shall pay Tenant's Share of such costs defined in paragraph 2.02(a)). At the end of the Lease, or any renewal thereof, Tenant shall quit and surrender the Premises broom clean and in as good condition as when received by Tenant, normal wear and tear excepted. 3.03(b) LANDLORD'S REPAIRS Except for repairs and replacements thereto that Tenant must make under paragraph 3.03(a), Landlord shall, at its expense, keep in good order, condition and repair, the common areas of the building, the roof of the building, the underground or otherwise concealed plumbing serving the building and the structural soundness of the foundations, exterior walls and the delivery of utilities to the Premises. Landlord shall, at its expense, keep in good order, condition and repair all driveways, parking lots, fences and signs (except for Tenant's fences and signs) located upon or comprising the property and all sidewalks and parkways adjacent to the Premises.

If Landlord fails to commence and thereafter diligently proceed to complete the repairs, Tenant may give Landlord a second notice, specifying the item to be repaired and stating Tenant's intent to complete the same if Landlord fails to do so. If Landlord fails to commence the work within fifteen (15) days thereafter, Tenant may complete such repair and shall be entitled to credit the reasonable cost of so doing against the next due installment of Rent. To the extent repairs to be performed by the Tenant are required in order to prevent the continued disruption of the operations of other tenants, then the Tenant shall make its repairs in accordance with this paragraph 3.03(c). 3.03(d) SURRENDERING THE PREMISES Upon the Ending Date, or the date of the last extension term, if any, whichever is later, Tenant shall surrender the Premises to Landlord in the same broom clean condition that the Premises were in on the Beginning Date except for: (i) Ordinary wear and tear; (ii) Damage by the elements, fire and other casualty unless Tenant would be required to repair under paragraph 3.03(a); (iii) Condemnation; (iv) Damage arising from any cause not required to be repaired or replaced by Tenant; and (v) Alterations as permitted by this Lease, unless consent was conditioned upon their removal. On surrender, Tenant shall remove from the Premises its personal property, trade fixtures and any alterations required to be removed under Section 4 and repair any substantial damage to the Premises caused by the removal. Tenant shall not be responsible for repairing any incidental damage caused by the removal of its personal property, trade fixtures and alterations.

The use of the Premises by a proposed subtenant or assignee must not violate or create any potential violation of any laws or violate any other agreements affecting the Premises, Landlord or other tenants.

If either party fails to give the required certificate with thirty (30) days after notice of demand for it, the other party may obtain and pay for that insurance and receive reimbursement from the party required to have the insurance. 5.02 INDEMNIFICATION 5.02(a) TENANT'S INDEMNITY Tenant indemnifies, defends and holds Landlord harmless from claims: (i) For personal injury, death or property damage; (ii) For incidents occurring in or about the Premises or building; and (iii) Caused by the negligence or willful misconduct of Tenant, its agents, employees or invitees. When the claim is caused by the joint negligence or willful misconduct of Tenant and Landlord, or Tenant and a third party unrelated to Tenant, except Tenant's agents, employees or invitees, Tenant's duty to defend, indemnify and hold Landlord harmless shall be in proportion to Tenant's allocable share of the joint negligence or willful misconduct. 5.02(b) LANDLORD'S INDEMNITY Landlord indemnifies, defends and holds Tenant harmless from claims: 12 (i) For personal injury, death or property damage; (ii) For incidents occurring in or about the Premises or building; and (iii) Caused by the negligence or willful misconduct of Landlord, its agents, employees or invitees. When the claim is caused by the joint negligence or willful misconduct of Landlord and Tenant, or Landlord and a third party unrelated to Landlord, except Landlord's agents, employees or invitees, Landlord's duty to defend, indemnify and hold Tenant harmless shall be in proportion to Landlord's allocable share of the joint negligence or willful misconduct. 5.02(c) RELEASE OF CLAIMS Notwithstanding paragraphs 5.02(a) and 5.02(b), the parties release each other from any claims either party (injured party) has against the other. This release is limited to the extent the claim is covered by the injured party's insurance or the insurance the injured party is required to carry under Section 5, whichever is greater. 5.03 LIMITATION OF LANDLORD'S LIABILITY 5.03(a) TRANSFER OF PREMISES Landlord hereby acknowledges that Tenant has agreed to lease the Premises based upon the complete expressed indemnification of the Tenant by the Landlord with regard to the Pre-Existing Environmental Conditions on the property. In the event ownership of the Premises is transferred by the Landlord, such transfer shall not serve to limit the Landlord's responsibilities and obligations to indemnify the Tenant for the Pre- Existing Environmental Conditions or any other responsibilities or obligations so specified under the Purchase and Sale Agreement by and between Alliant Techsystems Inc. and MAC Acquisition I, Inc. dated December 31, 1992. SECTION 6 - LOSS OF PREMISES 6.01 DAMAGES 6.01(a) DEFINITION "Relevant Space" means: (i) The Premises as defined in paragraph 1.02, excluding Tenant's non- building-standard fixtures; (ii) Access to the Premises; and (iii) Any part of the building that provides essential services to the Premises. 6.01(b) REPAIR OF DAMAGE If the Relevant Space is damaged in part or in whole from any cause and the Relevant Space can be substantially repaired and restored within ninety (90) days from the date of the damage using standard work methods and procedures, Landlord shall, at its expense, promptly and diligently repair and restore the Relevant Space to substantially the same condition as existed before the damage. This repair and restoration shall be made within ninety (90) days from the date of the damage. 13 If the Relevant Space is not insured or cannot be repaired and restored within the ninety (90) day period, then either party may, within ten (10) days after determining that the repairs and restoration cannot be made within ninety (90) days (as prescribed in paragraph 6.01(b)), cancel the Lease by giving notice to the other party. Nevertheless, if the Relevant Space is not repaired and restored within ninety (90) days from the date of damage, then Tenant may cancel the Lease at any time after the ninetieth (90th) day and before the one hundred and twentieth (120th) day following the date of damage. Tenant shall not be able to cancel this Lease if its willful misconduct causes the damage unless Landlord is not promptly and diligently repairing and restoring the Relevant Space. 6.01(c) DETERMINING THE EXTENT OF DAMAGE If the parties cannot agree in writing whether the repairs and restoration described in paragraph 6.01(b) will take more than ninety (90) days to make, then the determination will be submitted to arbitration under Section 11. 6.01(d) ABATEMENT Unless the damage is caused by the Tenant's negligence or willful misconduct, the Rent shall abate in proportion to that part of the Premises that is unfit for use in the Tenant's business. The abatement shall consider the nature and extent of interference to Tenant's ability to conduct business in the Premises and the need for access and essential services. The abatement shall continue from the date the damage occurred until ten (10) business days after Landlord completes the repairs and restoration to the Relevant Space, or the part rendered unusable and notice to the Tenant that the repairs and restoration are completed, or until Tenant again uses the Premises or the part rendered unusable, whichever is first. 6.01(e) TENANT'S PROPERTY Notwithstanding anything else in Section 6, Landlord is not obligated to repair or restore damage to Tenant's trade fixtures, furniture, equipment or other personal property, or any Tenant improvements other than those listed and attached hereto. 6.01(f) DAMAGE TO PREMISES If any of the following events occur, Landlord may cancel this Lease: (i) More than forty percent (40%) of the Premises is damaged and the Landlord decides not to repair and restore the Premises; (ii) The damage is not covered by Landlord's insurance required by paragraphs 5.01(a) and 5.01(b). To cancel, Landlord must give notice to Tenant within thirty (30) days after the Landlord knows of the damage. The notice must specify the cancellation date, which shall be at least thirty (30) days, but not more than sixty (60) days, after the date notice is given. 6.01(g) CANCELLATION If either party cancels this Lease as permitted by paragraphs 6.01(b) and 6.01(f), then this Lease shall end on the day specified in the cancellation notice. Rent and other charges shall be payable up to the cancellation date and shall account for any abatement. Landlord shall promptly refund to Tenant any prepaid, unaccrued Rent, accounting for any abatement, plus security deposit, if any, less any sum then owing by Tenant to Landlord. If Landlord cancels this Lease as permitted by paragraphs 6.01(b) and 6.01(f), then Landlord must cancel all other similarly affected tenant leases in the building. 6.02 CONDEMNATION 14 6.02(a) DEFINITIONS The terms "eminent domain," "condemnation," "taken" and the like in paragraph 6.02 include takings for public or quasi- public use and private purchase in place of condemnation by any authority authorized to exercise the power of eminent domain. 6.02(b) ENTIRE TAKING If the entire Premises or the portions of the building required for reasonable access to, or the reasonable uses of, the Premises are taken by eminent domain, this Lease shall automatically end on the earlier of: (i) The date title vests; or (ii) The date the Tenant is dispossessed by the condemning authority. 6.02(c) PARTIAL TAKING If the taking of a part of the Premises materially interferes with Tenant's ability to continue its business operations in substantially the same manner and space, then Tenant may end this Lease on the earlier of: (i) The date title vests; or (ii) The date the Tenant is dispossessed by the condemning authority; or (iii) Sixty (60) days following notice to Tenant of the date when vesting or disposition is to occur. If there is a partial taking and this Lease continues, then the Lease shall end as to the part taken and the Rent shall abate in proportion to the part of the Premises taken and Tenant's pro rata share shall be equally reduced. 6.02(d) TERMINATION BY LANDLORD If title to a part of the building other than the Premises is condemned and in the Landlord's reasonable opinion, the building should be restored in a manner that materially alters the Premises, Landlord may cancel this Lease by giving notice to the Tenant. Cancellation notice shall be given within sixty (60) days following the date title vested. This Lease shall end on the date specified in the cancellation notice, which date shall be at least thirty (30) days, but not more than ninety (90) days, after the date notice is given. 6.02(e) RENT ADJUSTMENT If the Lease is canceled as provided for in paragraphs 6.02(b), 6.02(c) or 6.02(d), then the Rent and other charges shall be payable up to the cancellation date and shall account for any abatement. Landlord, considering any abatement, shall promptly refund to Tenant any unpaid, unaccrued Rent plus security deposit, if any, less any sum then owing by Tenant to Landlord. 6.02(f) REPAIR If the Lease is not canceled as provided for in paragraphs 6.02(b), 6.02(c) or 6.02(d), then Landlord, at its expense, shall promptly repair and restore the Premises to the condition that existed immediately before the taking, except for the part taken, to render the Premises a complete architectural unit, but to the extent of the: 15 (i) Condemnation award received for the damage; and (ii) Building standard work. 6.02(g) AWARDS AND DAMAGES Landlord reserves all rights to damages paid because of any partial or entire taking of the Premises. Notwithstanding anything else in paragraph 6.02(g), Tenant may claim and recover from the condemning authority a separate award for Tenant's moving expenses, business dislocation damages, Tenant's personal property and fixtures, the unamortized costs of leasehold improvements paid for by Tenant and any other award that would not substantially reduce the award payable to Landlord. Each party shall seek its own award, as limited by paragraph 6.02(g), at its own expense and neither shall have any right to the award made to the other. 6.02(h) TEMPORARY CONDEMNATION If part or all of the Premises are condemned for a limited period of time of less than twenty (20) days (Temporary Condemnation), this Lease shall remain in effect. The Rent and Tenant's obligations for the part of the Premises taken shall abate during the Temporary Condemnation in proportion to the part of the Premises that Tenant is unable to use in its business operations as a result of the Temporary Condemnation. Landlord shall receive the entire award for any Temporary Condemnation; however, Tenant shall have the right to pursue a claim against the condemning authority separately. 6.03 HAZARDOUS MATERIALS 6.03(a) Landlord shall indemnify and hold Tenant harmless from any environmental costs relating to conditions existing on or before the effective date of this Lease and from the conduct of the Tenant's business during the first twelve (12) months of this lease; provided: (i) Tenant shall operate its business and handle, store and dispose of all hazardous materials ("Operation") under the same policies and procedures that the business was operated under during the twelve (12) month period prior to the effective date of this Lease; or (ii) Any change in the Operation is: (A) Caused by cessation of a portion of the business, or (B) Mutually agreed to in writing by Landlord and Tenant. Tenant shall allow Landlord to inspect and audit the Operations without prior notification. Tenant shall, at its cost, comply with all changes in the Operations: (i) As directed by Landlord in writing which are a result of Landlord's compliance audits or changes in Environmental Laws; or (ii) As directed in writing by any local, state or federal agency. 16 Tenant, at its cost, shall continue maintaining or continue the application process of all permits and licenses necessary for the Operations (but in no way associated with any remediation work) as directed by the Landlord. Tenant's failure to comply with Landlord or agency directed changes in the Operations shall be considered a breach of this Lease, for which the Landlord shall be entitled to recover its actual damages and any reasonable attorney's and consulting fees. 6.03(b) After the initial twelve (12) months of this Lease, Tenant shall comply with all Environmental Laws and shall indemnify and hold Landlord harmless from any Environmental Cost which is different in nature from Pre- Existing Conditions of the Premises, or which is attributable to actions taken by the Tenant after the initial twelve (12) month period and which results in a liability to Landlord and only to the extent it is greater than, or different from, the Landlord's liability for the Pre-Existing Conditions. Nothing in this paragraph 6.03 extends Landlord's obligations to Tenant for any environmental liabilities unrelated to the Premises. 6.03(c) The terms "Environmental Costs" and "Environmental Laws" shall have the same definitions as they do in the Purchase and Sale Agreement by and between Alliant Techsystems Inc. and MAC Acquisition I, Inc. dated December 31, 1992. The "Pre-Existing Conditions" shall mean the soil and ground water contamination in existence on December 31, 1992, and the conditions for which Landlord is responsible during the first twelve (12) months of this Lease under this paragraph 6.03. SECTION 7 - DEFAULT 7.01 TENANT'S DEFAULT Each of the following constitutes a default ("Default"): (i) Tenant's failure to pay Rent within fifteen (15) days after Tenant receives notice from Landlord of Tenant's failure to pay Rent; (ii) Tenant's failure to pay Rent by the due date, at any time during a calendar year in which the Tenant has already received three (3) notices of its failure to pay Rent by the due date; (iii) Tenant's failure to perform or observe any other Tenant obligation after a period of thirty (30) business days or the additional time, if any, that is reasonably necessary to promptly and diligently cure the failure, after it receives notice from Landlord setting forth in reasonable detail the nature and extent of the failure and identifying the applicable Lease provision(s); (iv) Tenant's abandoning or vacating the Premises if Tenant fails to pay the Rent by the due date; (v) The occurrence of any of the following events: (A) The making by Tenant of any general arrangement or assignment for the benefit of creditors: 17 (B) The Tenant's becoming a "debtor" as defined in Chapter 11, U. S. C. 101 or any successor statute thereto (unless in the case of a petition filed against the Tenant the same is dismissed within ninety (90) days); (C) The appointment of a trustee or receiver to take possession of substantially all of Tenant's assets located at the Premises or of Tenant's interest in this Lease, where possession is not restored to Tenant within sixty (60) days; or (D) The attachment, execution or other judicial seizure of substantially all of Tenant's assets located at the Premises or of Tenant's interest in this Lease where such seizure is not discharged within sixty (60) days; provided, however, in the event that any provision of this subparagraph 7.01(v) is contrary to any applicable law, such provision shall be of no force or effect and or affect the validity of the remaining provisions. 7.02 LANDLORD'S REMEDIES If Tenant fails to perform any affirmative duty or obligation of Tenant under this Lease, within thirty (30) days after receipt of written notice to Tenant (or in the case of an emergency, such lesser time that is prudent under the circumstances), Landlord may at its option (but without obligation to do so), perform such duty or obligation on Tenant's behalf, including but not limited to the obtaining of reasonable required bonds, insurance policies or governmental licenses, permits or approvals. The costs and expenses of any such performance by Landlord shall be due and payable by Tenant to Landlord upon invoice therefor. If any check given to Landlord by Tenant shall not be honored by the bank upon which it is drawn, Landlord, at its option, may require all future payments to be made under this Lease by Tenant to be made only by cashier's check. In the event of a Default of this Lease by Tenant, as defined in paragraph 7.01, Landlord may, in addition to all other remedies given to Landlord by law or in equity, by written notice to Tenant, declare the present value of all installments of Base Rent for the remainder of the term of this Lease to be immediately due and payable (whereupon the same shall be immediately due and payable), and terminate this Lease or, without terminating this Lease, reenter the Premises pursuant to proper legal proceedings (for which cost Landlord shall be reimbursed if such reentry is granted). In the event of such re-entry Landlord shall use its reasonable efforts to relet the Premises and in the event of such reletting shall apply the rent therefrom first to the payment of Landlord's expenses (including reasonable attorneys' fees) incurred by reason of Tenant's Default and the expense of reletting, including but not limited to repairs, renovation or alteration of the Premises, and then to the payment of Rent and all other sums due from Tenant hereunder. All remedies available to Landlord under this Lease, at law, or in equity, are cumulative and concurrent. No termination of this Lease nor any taking or recovering of possession of the Premises shall deprive Landlord of any of its remedies or actions against Tenant for past or future rent or other sums due hereunder, nor shall the bringing of any action for rent or other Default be construed as a waiver of the right to obtain possession of the Premises. 18 7.03 LANDLORD'S DEFAULT Landlord's failure to perform or observe any of its Lease obligations after a period of thirty (30) business days or the additional time, if any, that is reasonably necessary to promptly and diligently cure the failure after receiving notice from Tenant, is a Default. The notice shall give in reasonable detail the nature and extent of the failure and identify the Lease provision(s) containing the obligation(s). After Tenant receives notice of a mortgagee's name and address and request for notice upon Landlord's Default, Tenant shall provide the notice required by this paragraph to the mortgagee at the same time Tenant gives notice to Landlord. If Landlord commits a Default, Tenant may pursue any remedies given in this Lease or under the law. 7.04 EXCEPTION TO CURE PERIODS The cure periods in paragraphs 7.01 and 7.03 do not apply to: (i) Emergencies; (ii) Failure to maintain the insurance required by paragraph 5.01. 7.05 SELF-HELP If either party Defaults ("Defaulting Party"), the other party ("Non-Defaulting Party") may, without being obligated and without waiving the Default, cure the Default. The Non-Defaulting Party may enter the Premises or building to cure the Default. The Defaulting Party shall pay the Non-Defaulting Party, upon demand, all costs, expenses and disbursements incurred by the Non-Defaulting Party to cure the Default. 7.06 SURVIVAL The remedies permitted by Section 7, the parties' indemnities in paragraph 5.02 and Landlord's obligation to mitigate damages shall survive the ending of this Lease. SECTION 8 SUBORDINATION/ATTORNMENT/NON-DISTURBANCE 8.01 SUBORDINATION/ATTORNMENT/NON-DISTURBANCE 8.01(a) SUBORDINATION This lease shall be subject and subordinate to any ground lease, mortgage, deed of trust or other hypothecation or security device (collectively "Security Device") now or hereafter placed by Landlord upon the real property of which the Premises are a part, to any and all advances made on the security thereof and to all renewal, modifications, consolidations, replacements and extensions thereof. Tenant agrees that the lenders holding any such Security Device shall have no duty, liability or obligation to perform any of the 19 obligations of Landlord under this Lease, but that in the event of Landlord's Default with respect to any such obligation, Tenant will give any lender whose name and address have been furnished Tenant in writing for such purposes notice of Landlord's Default and allow such lender thirty (30) days following receipt of such notice for the cure of said Default before invoking any remedies Tenant may have by reason thereof. If any lender shall elect to have this Lease superior to the lien of its Security Device and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such Security Device, notwithstanding the relative dates of the documentation or recording thereof. 8.01(b) ATTORNMENT Subject to the non-disturbance provisions of paragraph 8.01(c), Tenant agrees to attorn to a lender or any other party who acquires ownership of the Premises by any reason. 8.01(c) NON-DISTURBANCE With respect to any Security Device entered into by Landlord after the execution of this Lease, Tenant's subordination of this Lease shall be subject to receiving assurance (a non-disturbance agreement) in a form reasonably acceptable to Tenant from the lender that Tenant's possession and this Lease, including any options to extend the term hereof, will not be disturbed so long as Tenant is not in breach hereof and attorns to the recorded owner of the Premises 8.01(d) SELF-OPERATING Paragraph 8.01 is self-operating. However, Tenant shall promptly execute and deliver any documents needed to confirm this arrangement. 8.02 ESTOPPEL CERTIFICATE 8.02(a) OBLIGATION Either party ("Answering Party") shall from time to time, within ten (10) business days after receiving a written request by the other party ("Asking Party"), execute and deliver to the Asking Party a written statement. This written statement, which may be relied upon by the Asking Party and any third party with whom the Asking Party is dealing, shall certify: (i) The accuracy of the Lease document; (ii) The Beginning and Ending Dates of the Lease; (iii) That the Lease is unmodified and in full effect or in full effect as modified, stating the date and nature of the modification; (iv) Whether to the Answering Party's knowledge the Asking Party is in Default or whether the Answering Party has any claims or demands against the Asking Party and, if so, specifying the Default, claim or demand; and (v) To otherwise correct and reasonably ascertainable facts that are covered by the Lease terms. 20 8.02(b) REMEDY The Answering Party's failure to comply with its obligation in paragraph 8.02(a) shall be a Default. Notwithstanding subparagraphs 7.01(i), 7.01(iii), 7.01(v) and paragraph 7.03, the cure period for this Default shall be ten (10) business days after the Answering Party receives notice of the Default. 8.03 QUIET POSSESSION Landlord covenants that, upon the payment of Rent and observance and performance by Tenant of all the terms, covenants and conditions of this Lease on Tenant's part to be observed and performed, Tenant may peaceably and quietly enjoy the Premises, subject, nevertheless, to the terms and conditions of this Lease. Landlord warrants that it owns the building free and clear of all encumbrances except those listed below: (i) Credit Agreement dated September 25, 1990, by and between Alliant Techsystems Inc. and Morgan Guaranty Trust Company of New York acting as agent for certain banks and institutions. If Tenant is not in Default and subject to the Lease terms and the above encumbrances, Landlord warrants that Tenant's peaceable and quiet enjoyment of the Premises shall not be disturbed by anyone. SECTION 9 - LANDLORD'S RIGHTS 9.01 RULES 9.01(a) RULES Tenant, its employees and invitees shall comply with: (i) The Rules attached as Exhibit B; and (ii) Reasonable modifications and additions to the Rules adopted by Landlord provided that: (A) Tenant is given thirty (30) days advance notice; (B) The changes are for the safety, care, order or cleanliness of the common areas; (C) The changes do not unreasonably and materially interfere with the Tenant's conduct of its business or Tenant's use and enjoyment of the Premises: (D) The changes do not require payment of additional moneys by or result in an expense to Tenant; and (E) The changes are enforced uniformly against all tenants. 9.01(b) CONFLICT WITH LEASE If a Rule issued under paragraph 9.01(a) conflicts with or is inconsistent with any Lease provision, the Lease provision controls. 21 9.01(c) ENFORCEMENT Although Landlord is not responsible for another tenant's failure to observe the Rules, Landlord shall not unreasonably enforce the Rules against Tenant. 9.02 MECHANIC'S LIENS 9.02(a) DISCHARGE LIEN Tenant shall, within sixty (60) days after receiving notice of any mechanic's lien for material or work claimed to have been furnished to the Premises on Tenant's behalf and at Tenant's request, except for work contracted by Landlord: (i) Discharge the lien; or (ii) Post a bond equal to the amount of the disputed claim with companies reasonably satisfactory to Landlord. If Tenant posts a bond, it shall contest the validity of the lien. Tenant shall indemnify, defend and hold Landlord harmless from losses incurred from these liens. 9.02(b) LANDLORD'S DISCHARGE If Tenant does not discharge the lien or post the bond within the sixty (60) day period, Landlord may pay any amounts, including interest and legal fees, to discharge the lien. Tenant shall then be liable to Landlord for the amounts paid by Landlord. 9.02(c) CONSENT NOT IMPLIED Paragraph 9.02 is not a consent to subject Landlord's property to these liens. 9.03 RIGHT TO ENTER 9.03(a) PERMITTED ENTRIES Landlord and its agents, servants and employees may enter the Premises (except restricted areas as designated by Tenant's Security Officer) at reasonable times, with twenty-four (24) hours notice to the Tenant (seven (7) days notice to make repairs, alterations, improvements or additions), without charge, liability or abatement of Rent to: (i) Examine the Premises; (ii) Make repairs, alterations, improvements and additions required by the Lease; (iii) Comply with Applicable Laws under paragraph 3.01; (iv) Show the Premises to prospective lenders or purchasers and, during the twelve (12) months immediately before this Lease ends, to prospective tenants if accompanied by an employee of Tenant (if so requested); 22 (v) Post notices of non-responsibility; (vi) Remove any Alterations made by Tenant in violation of paragraph 4.02; and (vii) Post "For Sale" signs and, during the twelve (12) months immediately before this Lease ends, post "For Lease" signs. 9.03(b) ENTRY CONDITIONS Notwithstanding paragraph 9.03(a), entry is conditioned upon Landlord: (i) Giving Tenant at least twenty-four (24) hours advance notice, except in an emergency; (ii) At the Tenant's option, to have an employee of Tenant accompany the Landlord, its employees or agents at all times while on the Premises; (iii) Promptly finishing any work for which it entered; and (iv) Causing the least practical interference to Tenant's business. 9.03(c) INTERFERENCE WITH TENANT Notwithstanding paragraphs 9.03(a) and (b): (i) If Landlord's entry materially and substantially interferes with the conduct of the Tenant's business (and the entry is not needed because of Tenant's negligence or willful misconduct), the Rent shall abate in proportion to the extent of the interference; and (ii) If the Landlord causes damage to Tenant's property, Landlord shall be liable for any damage to the extent the damage is not covered by Tenant's insurance or insurance Tenant is required to carry under Section 5, whichever is greater. 9.04 HOLDOVER 9.04(a) HOLDOVER STATUS If, at the expiration or termination of this Lease, Tenant shall, with the express consent of Landlord, hold over for any reason, the tenancy of Tenant thereafter shall be on a month-to-month basis only at 1.15 times the Base Rent with each party retaining the right to terminate the Lease by providing thirty (30) days advance notice to the other party. 9.04(b) HOLDOVER TERMS The Holdover period shall, in the absence of a written agreement to the contrary, be subject to all other terms and conditions of the Lease except: (i) The term (paragraph 1.04); (ii) Base Rent (paragraphs 2.01); and (iii) The extension term is deleted (paragraph 1.04(b)). 9.05 SIGNS AND ADVERTISEMENTS 23 Landlord shall reasonably consent to the placement of signs on the property by the Tenant at Tenant's cost.

SECTION 10 - OTHER LEASES AND ACCESS TO PREMTISES 10.01 THIRD PARTY LEASES Landlord intends to lease to third parties portions of the building that are not being utilized by Tenant during the term of this Lease, provided that the Landlord agrees that it shall not lease any space on the property to any actual or reasonably potential competitors of the Tenant. Landlord further agrees that it shall include in all leases involving other portions of the buildings, requirements for the compliance with the applicable rules and regulations regarding the discharge, handling and storage of hazardous waste. The Landlord agrees to require each such tenant to provide Landlord with a list of all such hazardous materials used in or about its premises on or before the commencement date of its lease and that such list shall be updated on an annual basis. Landlord will make available a copy of this list to the Tenant upon Tenant's request. 10.02 ENVIRONMENTAL REMEDIATION Landlord intends to perform investigations and remediation work with respect to the Pre-Existing Environmental Conditions on a portion of the Premises ("Work").

Landlord agrees to indemnify and hold Tenant harmless from all loss, cost, damage, suits and expenses incurred by Tenant by virtue of Tenant permitting such access and use as described in this paragraph 10.02. This indemnity shall survive the termination or earlier expiration of this Lease. SECTION 11- DISPUTES 11.01 ARBITRATION 11.01(a) PROCEDURE For disputes subject to arbitration under paragraph11.01(c) that are not resolved by the parties within ten (10) days after either party gives notice to the other of its desire to arbitrate the dispute, the dispute shall be settled by binding arbitration by the American Arbitration Association in accordance with its then prevailing rules. Judgment upon the arbitration award may be entered in any courts having jurisdiction. The 24 arbitrators shall have no power to change the Lease provisions. The arbitration panel shall consist of three (3) arbitrators, one of whom must be a real estate attorney actively engaged in the practice of law for at least the last five (5) years. Both parties shall continue performing their Lease obligations pending the award in the arbitration proceeding. The arbitrators shall award the prevailing party reasonable expenses and costs (including reasonable attorneys' fees pursuant to paragraph 12.02), plus interest on the amount due at eighteen percent (18%) per annum, or the maximum then allowed by applicable law, whichever is less. 11.01(b) PAYMENT The losing party shall pay to the prevailing party the amount of the final arbitration award.

Dry Creek Road Littleton, CO 80122-3700 RE: Letter of Understanding Dear Mr. Krauss: As you know, Alliant Techsystems, Inc. ("Alliant") has entered into negotiating with Chesapeake Park, Inc. ("Chesapeake"), as agent for Lockheed Martin Missile and Space, for the lease of space in the building located at 4810 Dry Creek Road, Littleton, Colorado 80112 ("Leased Building"). It is our understanding that Metrum, Inc. ("Metrum") has verbally agreed to vacate certain space which it currently leases in order to accommodate these negotiations. Although Alliant and Chesapeake have arrived at a verbal understanding, they have not yet entered into a written agreement and do not expect to execute a formal document for at least sixty days. However, in order to meet Chesapeake's anticipated time frame, Alliant has asked Metrum to vacate certain space in the Leased Building within the next thirty days in the anticipation that Alliant and Chesapeake will reach a formal agreement. This letter of understanding is given to Metrum for the purpose of inducing Metrum to so vacate and take all other actions necessary to properly prepare for Chesapeake's occupancy of the Leased Building. Based on such understanding, Alliant and Metrum hereby agree to the following: 1. Metrum will vacate approximately 34,000 square feet of currently leased space located on the east side of the Leased Building. The space will be vacated by November 30, 1995. 2. Metrum will pay its own expenses for relocating its Head and Motors manufacturing activities to its remaining leased space. In the event that Alliant and Chesapeake reach formal agreement as per the Leased Building, Alliant and Metrum will be obligated as follows: 1. Metrum will be relieved of paying any rental expenses associated with the vacated space as of November 30, 1995. 2. Chesapeake's occupancy of the Leased Building may necessitate Metrum's relocation of its presently situated bathrooms and lobby. Alliant hereby agrees and pledges to reimburse Metrum for all costs incurred by Metrum should it become necessary to relocate such facilities. If building operations require additional bathrooms for either Metrum or Chesapeake's occupancy, every attempt shall be made for both parties to share the existing bathroom facilities. In the event that additional bathrooms need to be constructed, such bathrooms will be built next to existing bathrooms and plumbing. Moreover, Alliant agrees that such relocated facilities shall be of comparable quality and dimension and agrees to pay for the expense associated therewith. Such expenses for the lobby are not to exceed $50,000.00. Alliant shall be responsible for such costs. 3. Alliant and Metrum will enter into a written amendment to that certain Industrial Lease dated March 29, 1993 entered into by and between Alliant and Metrum which will formally recognize that Alliant has released Metrum from any and all obligations associated with the vacated square footage of the Leased Building. 34 4. The water tower lettering shall be painted to match the tower color with no identity for either party. The monument sign will be enlarged (subject to any city and county codes or comments) to accommodate both companies with Lockheed Martin Missile & Space on top. Any other site signage will be changed so as not to identify either company. In the event that Alliant and Chesapeake fail to reach formal agreement as per the Leased Building, Alliant and Metrum will be obligated as follows: 1. Alliant hereby agrees to provide Metrum with formal notification of the irretrievable breakdown of its negotiations with Chesapeake within three days following such event. 2. Alliant hereby agrees to pay and reimburse Metrum for the actual expense incurred in its move from the leased space which occurred on November 30, 1995, and, if Metrum determines that it is necessary to move back into the vacated space. Alliant hereby agrees to pay and reimburse Metrum for the actual expenses incurred in such second move. The total amount of Alliant's liability for such reimbursed actual expenses shall not exceed $320,000. Please show your acceptance of these terms and conditions by signing below.
