2.2    Condition. Sublessor shall deliver Hangar B and Hangar C to Sublessee broom clean and free of debris upon delivery of the completed “shell” evidenced by a notice of completion or similar notice delivered from the City of Mesa AZ Building Department and covenants, represents and warrants to Sublessee that (i) the Sublease Premises shall be delivered in accordance with all Applicable Requirements, including without limitation, the Americans with Disabilities Act, (ii) Sublessee shall incur no costs as a result of the inaccuracy of such covenant, representation and warranty, (iii) Sublessor shall remedy, at its sole cost and not as a Common Area Operating Expense, any violation of such covenants, representations and warranties, including without limitation, patent and latent defects discovered at any time during the Term as extended, (iv) the electrical, plumbing, fire sprinkler, lighting, heating, ventilating and air conditioning systems ("HVAC"), loading doors, and all other such elements in the Sublease Premises, other than those constructed by Sublessee, shall be in good operating condition on said date, (v) the structural elements of the roof, bearing walls and foundation of the Sublease Premises shall be free of material defects, and (vi) the Sublease Premises do not contain any Hazardous Substances (defined below) or hazardous levels of any mold or fungi defined as toxic under applicable state or federal law. If a non-compliance with such representation and warranty exists as of the Rent Commencement Date for Hangar B or Rent Commencement Date for Hangar C, or if one of such systems or elements should malfunction or fail due to a patent or latent defect, during the Term, as such Term may be extended, Sublessor shall promptly after receipt of written notice from Sublessee setting forth with specificity the nature and extent of such non-compliance, malfunction or failure, promptly rectify same at Sublessor's expense but in no event later than thirty (30) days following Sublessor’s receipt of written notice of such malfunction or failure. If Sublessee does not give Sublessor the required notice within the appropriate warranty period, correction of any such non-compliance, malfunction or failure shall be the obligation of Sublessee at Sublessee's sole cost and expense (except for the repairs to the fire sprinkler systems, roof, foundations, and/or bearing walls - see Paragraph 6). Sublessor also represents and warrants, that unless otherwise specified in writing, Sublessor is unaware of (i) any recorded Notices of Default affecting the Sublease Premises; (ii) any delinquent amounts due under any loan secured by the Sublease Premises; and (iii) any bankruptcy proceeding affecting the Sublease Premises.

2.3    Compliance. Sublessor represents and warrants that the Buildings and common areas of the Project comply with the building codes, applicable laws, covenants or restrictions of record, regulations, and ordinances, including without limitation, the Americans with Disabilities Act ("Applicable Requirements") that were in effect as of the applicable Rent Commencement Date for Hangar B and Hangar C. In no event shall Sublessee be responsible for any costs arising from the inaccuracy of such representation and warranty and Sublessor shall remedy any violation hereof, including latent and patent defects at any time during the Term, as the term may be extended. Said representation and warranty does not apply to the use to which Sublessee will put the Sublease Premises, modifications which may be required by the Americans with Disabilities Act or any similar laws as a result of Sublessee’s use (see Paragraph 48), or to any Alterations or Utility Installations (as defined in Paragraph 6.3(a)) made or to be made by Sublessee. NOTE: Sublessee is responsible for determining whether or not the Applicable Requirements, and especially the zoning are appropriate for Sublessee’s intended use. If the Sublease Premises do not comply with said representation and warranty, Sublessor shall, except as otherwise provided, promptly after receipt of written notice from Sublessee setting forth with specificity the nature and extent of such non-compliance, rectify the same at Sublessor's sole expense without reimbursement. If the Applicable Requirements are changed after the applicable Rent Commencement Date for Hangar B or Hangar C so as to require during the Term of this Sublease the construction of an addition to or an alteration of the Sublease Premises and/or Buildings, the remediation of any Hazardous Substance, or the reinforcement or other physical modification of the Sublease Premises and/or Buildings ("Capital Expenditure"), Sublessor and Sublessee shall allocate the cost of such work as follows:

(a)    Subject to Paragraph 2.3(c) below, if such Capital Expenditures are required as a result of the specific and unique use of the Sublease Premises by Sublessee as compared with uses by subtenants in general at the Project, Sublessee shall be fully responsible for the cost thereof, provided, however, that if such Capital Expenditure is required during the last 2 years of the Term of this Sublease and the cost thereof exceeds 6 months' Base Rent, Sublessee may instead terminate this Sublease unless Sublessor notifies Sublessee, in writing, within 10 business days after receipt of Sublessee's termination notice that Sublessor has elected to pay the difference between the actual cost thereof and the amount equal to 6 months' Base Rent. If Sublessee elects termination, Sublessee shall cease the use of the Sublease Premises which requires such Capital Expenditure and deliver to Sublessor written notice specifying a termination date at least 30 days thereafter. Such termination date shall, however, in no event be earlier than the last day that Sublessee could legally utilize the Sublease Premises without commencing such Capital Expenditure.

(b)    If such Capital Expenditure is not the result of the specific and unique use of the Sublease Premises by Sublessee (such as, governmentally mandated seismic modifications), then Sublessor shall pay for such Capital Expenditure and Sublessee shall only be obligated to pay, each month during the remainder of the Term of this Sublease or any extension thereof, on the date that on which the Base Rent is due, an amount equal to 1/144th of the portion of such costs reasonably attributable to the Sublease Premises. Sublessee shall pay Interest on the balance but may prepay its obligation at any time. If, however, such Capital Expenditure is required during the last 2 years of this Sublease or if Sublessor reasonably determines that it is not economically feasible to pay its share thereof, Sublessor shall have the option to terminate this Sublease upon 90 days prior written notice to Sublessee unless Sublessee notifies Sublessor, in writing, within 10 business days after receipt of Sublessor's termination notice that Sublessee will pay for such Capital Expenditure. If Sublessor does not elect to terminate, and fails to tender its share of any such Capital Expenditure, Sublessee may advance such funds and deduct same, with Interest, from Base Rent until Sublessor's share of such costs have been fully paid. If Sublessee is unable to finance Sublessor's share, or if the balance of the Rent (as defined in Paragraph 4.1) due and payable for the remainder of this Sublease is not

sufficient to fully reimburse Sublessee on an offset basis, Sublessee shall have the right to terminate this Sublease upon 30 days written notice to Sublessor.

(c)    Notwithstanding the above, the provisions concerning Capital Expenditures are intended to apply only to non-voluntary, unexpected, and new Applicable Requirements. If the Capital Expenditures are instead triggered by Sublessee as a result of an actual or proposed change in use, change in intensity of use, or modification to the Sublease Premises made following the installation of Sublessee’s tenant improvements then, and in that event, Sublessee shall either: (i) immediately cease such changed use or intensity of use and/or take such other steps as may be necessary to eliminate the requirement for such Capital Expenditure, or (ii) complete such Capital Expenditure at its own expense.

(d)    Sublessee's Share of Common Area Operating Expenses is payable monthly on the same day as the Base Rent is due hereunder. The amount of such payments shall be based on

If Sublessee's payments during such calendar year exceed Sublessee's Share, Sublessor shall credit the amount of such over-payment against Sublessee's then immediately following future payments. If Sublessee's payments during such calendar year were less than Sublessee's Share, Sublessee shall pay to Sublessor the amount of the deficiency within 30 days after delivery by Sublessor to Sublessee of the statement.

(e)    Common Area Operating Expenses shall not include any expenses paid by any tenant or subtenant directly to third parties, or as to which Sublessor is otherwise reimbursed by any third party, other tenant or subtenant, or insurance proceeds.

In no event shall Sublessee be liable for the payment of any Common Area Operating Expense of which Sublessee first receives written notice in excess of one (1) year following the expiration of the calendar year in which such Common Area Operating Expense was originally incurred. If Sublessee has overpaid by more than an amount equal to five percent (5%) of Common Area Operating Expenses in the applicable calendar year, Sublessor shall pay the reasonable out-of-pocket cost of the review of Sublessor’s records and the reasonable out-of-pocket cost of the review of Sublessor’s records.

4.3    Payment. Sublessee shall cause payment of Rent to be received by Sublessor in lawful money of the United States, without offset or deduction (except as specifically permitted in this Lease), on or before the day on which it is due.

In the event that any invoice prepared by Sublessor is inaccurate such inaccuracy shall not constitute a waiver and Sublessee shall be obligated to pay the amount set forth in this Sublease. Rent for any period during the Term hereof which is for less than one full calendar month shall be prorated based upon the actual number of days of said month. Payment of Rent shall be made to Sublessor at its address stated herein or to such other persons or place as Sublessor may from time to time designate in writing. Acceptance of a payment which is less than the amount then due shall not be a waiver of Sublessor's rights to the balance of such Rent, regardless of Sublessor's endorsement of any check so stating. In the event that any check, draft, or other instrument of payment given by Sublessee to Sublessor is dishonored for any reason, Sublessee agrees to pay to Sublessor the sum of $[***] in addition to any Late Charge and Sublessor, at its option, may require all future Rent be paid by cashier's check.

4.4    Rental Taxes. In addition to Base Rent and Common Area Operating Expenses, Sublessee shall pay to Sublessor each month an amount equal to any rental taxes, gross receipts taxes, transaction privilege taxes, sales taxes, or similar taxes levied on the Base Rent and Common Area Operating Expenses then due or otherwise assessed in connection with the rental activity.

Sublessee shall, at Sublessee's sole expense, procure and maintain contracts, with copies to Sublessor, in customary form and substance for, and with contractors specializing and experienced in the maintenance of the following equipment and improvements, if any, if and when installed on the Sublease Premises: (i) HVAC equipment, (ii) boiler and pressure vessels, and (iii) clarifiers.

(c)    Failure to Perform. If Sublessee fails to perform Sublessee's obligations under this Paragraph 6.1, Sublessor shall give Sublessee written notice of such failure and if such failure is not cured by Sublessee within thirty (30) days following Sublessor’s written notice to Sublessee, may enter upon the Sublease Premises at any time thereafter (in the case of an emergency, no notice shall be required but Sublessor shall use its best efforts to provide prior notice), perform such obligations on Sublessee's behalf, and put the Sublease Premises in good order, condition and repair, and Sublessee shall promptly pay to Sublessor a sum equal to 105% of the actual and reasonable cost thereof.

(d)    Replacement. Subject to Sublessee's indemnification of Sublessor as set forth in Paragraph 7.8 below, and without relieving Sublessee of liability resulting from Sublessee's failure to exercise and perform good maintenance practices, if an item described in Paragraph 6.1(b) cannot be repaired other than at a cost which is in excess of 50% of the cost of replacing such item, then such item shall be replaced by Sublessor, and the cost thereof shall be prorated between the Parties and Sublessee shall only be obligated to pay, each month during the remainder of the Term of this Sublease or any extension thereof, on the date on which Base Rent is due, an amount equal to the product of multiplying the cost of such replacement by a fraction, the numerator of which is one, and the denominator of which is 144 (i.e. 1/144th of the cost per month), which amortization shall fully repay all of such cost of replacing such item plus Interest. Sublessee shall pay Interest on the unamortized balance at a rate not to exceed seven percent (7%) per annum but may prepay its obligation at any time.

6.2    Sublessor's Obligations. Subject to the provisions of Paragraphs 2.2 (Condition), 2.3 (Compliance), 4.2 (Common Area Operating Expenses), 5 (Use), 6.1 (Sublessee's Obligations), 8 (Damage or Destruction) and 13 (Condemnation), Sublessor, subject to reimbursement pursuant to Paragraph 4.2, shall keep in good order, condition and repair the foundations, exterior walls, structural condition of interior bearing walls, exterior roof, fire sprinkler system, Common Area fire alarm and/or smoke detection systems, fire hydrants, parking lots, walkways, parkways, driveways, landscaping, fences, signs and utility systems serving the Common Areas and all parts of the Common Areas, as well as providing the services for which there is a Common Area Operating Expense pursuant to Paragraph 4.2. Sublessor shall not be obligated to paint the exterior or interior surfaces of exterior walls nor shall Sublessor be obligated to maintain, repair or replace windows, doors or plate glass of the Sublease Premises.

6.3    Utility Installations; Trade Fixtures; Alterations.

(a)    Definitions. The term "Utility Installations" refers to all floor and window coverings, air and/or vacuum lines, power panels, electrical distribution, security and fire protection systems, communication cabling, lighting fixtures, HVAC equipment, plumbing, and fencing in or on the Sublease Premises. The term "Trade Fixtures" shall mean Sublessee's machinery and equipment that can be removed without doing material damage to the Sublease Premises. The term "Alterations" shall mean any modification of the improvements, other than Utility Installations or Trade Fixtures, whether by addition or deletion. "Sublessee Owned Alterations and/or Utility Installations" are defined as Alterations and/or Utility Installations made by Sublessee that are not yet owned by Sublessor pursuant to Paragraph 6.4(a). This Section 6.3 shall not govern the installation, removal or restoration of the improvements to be installed pursuant to Exhibit C and Exhibit C shall govern all such matters.

(b)    Consent. Subject to the terms and conditions of the Land Lease (including without limitation, obtaining Land Lessor’s prior written consent to any Alterations or Utility Installations), Sublessee shall have the right to make any Alterations or Utility Installations to the Sublease Premises as Sublessee deems appropriate, subject to Applicable Requirements and Sublessor's prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed unless such items would create substantial safety concerns for Sublessor, in Sublessor’s reasonable determination. In the event Sublessor shall not consent to any Alterations or Utility Installations requested by Sublessee, Sublessor shall specify in detail the specific reasons therefor. Subject to the terms of the Land Lease, Sublessee may, however, make non-structural Alterations or Utility Installations to the interior of the Sublease Premises (excluding the roof) without such consent but upon notice to Sublessor, as long as they are not visible from the outside, do not involve puncturing, relocating or removing the roof or any existing walls. Notwithstanding the foregoing, Sublessee shall not make or permit any roof penetrations and/or install anything on the roof without the prior written approval of

Sublessor, not to be unreasonably withheld, conditioned or delayed. Sublessor may, as a precondition to granting approval for Alterations which require Sublessor’s approval, require Sublessee to utilize a contractor chosen and/or approved by Sublessor. Any Alterations or Utility Installations that Sublessee shall desire to make and which require the consent of Sublessor shall be presented to Sublessor and Land Lessor in written form with detailed plans. Consent shall be deemed conditioned upon Sublessee's: (i) acquiring all applicable governmental permits, (ii) furnishing Sublessor with copies of both the permits and the plans and specifications prior to commencement of the work, and (iii) compliance with all conditions of said permits and other Applicable Requirements in a prompt and expeditious manner. Any Alterations or Utility Installations shall be performed in a workmanlike manner with good and sufficient materials. If applicable, Sublessee shall promptly upon completion furnish Sublessor with as-built plans and specifications.

(c)    Liens; Bonds. Sublessor shall have no lien on any of the Trade fixtures, Alterations or utility Installations of Sublessee. Sublessee shall pay, when due, all claims for labor or materials furnished or alleged to have been furnished to or for Sublessee at or for use on the Sublease Premises, which claims are or may be secured by any mechanic's or materialmen's lien against the Sublease Premises or any interest therein. Sublessee shall give Sublessor not less than ten (10) days’ notice prior to the commencement of any work in, on or about the Sublease Premises, and Sublessor shall have the right to post notices of non-responsibility. Sublessee shall keep the Sublease Premises and all improvements constructed by Sublessee thereon free of any mechanic or materialmen’s liens. In the event that any such lien is filed, Sublessee shall, at its sole cost, cause such lien to be removed from the Sublease Premises by bonding or otherwise within thirty (30) calendar days of notice thereof.

6.4    Ownership; Removal; Surrender; and Restoration.

(a)    Ownership. Except as provided in Paragraph 6.4(b) of this Sublease and Section 7.4 of the First Amendment to Land Lease, all Alterations and/or Sublessee Owned Alterations and Utility Installations shall, at the expiration or termination of this Sublease, become the property of Sublessor and be surrendered by Sublessee with the Sublease Premises.

(b)    Removal. Subject to the terms of Section 7.4 of the First Amendment to the Land Lease, Sublessor may require that any or all Alterations and/or Sublessee Owned Alterations and Utility Installations be removed by the expiration or termination of this Sublease by Sublessor requiring such removal at the time Sublessor consented to such installation or if Sublessor’s consent was not required to be requested, then no later than 6 months prior to the expiration or termination of the Term.

(c)    Surrender; Restoration. Sublessee shall surrender the Sublease Premises by the Expiration Date or any earlier termination date, with all of the improvements, parts and surfaces thereof broom clean and free of debris, and in good operating order, condition and state of repair, ordinary wear and tear excepted. "Ordinary wear and tear" shall not include any damage or deterioration that would have been prevented by good maintenance practice. Sublessee shall also remove from the Sublease Premises any and all Hazardous Substances brought onto the Sublease Premises by or for Sublessee (except Hazardous Substances which were deposited via underground migration from areas outside of the Project) to the level specified in Applicable Requirements. Trade Fixtures shall remain the property of Sublessee and shall be removed by Sublessee. Any personal property of Sublessee not removed on or before the Expiration Date or any earlier termination date shall be deemed to have been abandoned by Sublessee and may be disposed of or retained by Sublessor as Sublessor may desire. The failure by Sublessee to timely vacate the Sublease Premises pursuant to this

Paragraph 6.4(c) without the express written consent of Sublessor shall constitute a holdover under the provisions of Paragraph 25 below.

7.    Insurance; Indemnity.

7.1    Payment of Premiums. The cost of the premiums for the insurance policies required to be carried by Sublessor, pursuant to Paragraphs 7.2(b), 7.3(a) and 7.3(b), shall be a Common Area Operating Expense. Premiums for policy periods commencing prior to, or extending beyond, the term of this Sublease shall be prorated to coincide with the corresponding Commencement Date or Expiration Date.

7.2    Liability Insurance.

(a)    Carried by Sublessee. Sublessee shall obtain and keep in force a Commercial General Liability policy of insurance protecting Sublessee and Sublessor as an additional insured against claims for bodily injury, personal injury and property damage based upon or arising out of the ownership, use, occupancy or maintenance of the Sublease Premises and all areas appurtenant thereto. Such insurance shall be on an occurrence basis providing single limit coverage in an amount not less than $[***] per occurrence with an annual aggregate of not less than $[***]. Sublessee shall add Sublessor as an additional insured by means of an endorsement at least as broad as the Insurance Service Organization's "Additional Insured-Managers or Lessors of Premises" Endorsement. The policy shall not contain any intra-insured exclusions as between insured persons or organizations, but shall include coverage for liability assumed under this Sublease as an "insured contract" for the performance of Sublessee's indemnity obligations under this Sublease. The limits of said insurance shall not, however, limit the liability of Sublessee nor relieve Sublessee of any obligation hereunder. Sublessee shall provide an endorsement on its liability policy(ies) which provides that its insurance shall be primary to and not contributory with any similar insurance carried by Sublessor, whose insurance shall be considered excess insurance only.

(b)    Carried by Sublessor. Sublessor shall maintain liability insurance as described in Paragraph 7.4, in addition to, and not in lieu of, the insurance required to be maintained by Sublessee. Sublessee shall not be named as an additional insured therein.

7.3    Sublessee Insurance.

(a)     Form. Each insurance policy obtained pursuant to this Paragraph 7.3, except for Worker’s Compensation and Employer’s Liability policies, shall: (i) name Sublessor as a certificate holder or additional named insured; (ii) contain a provision that written notice of cancellation or modification thereof shall be given to Sublessor not less than thirty (30) days before such cancellation or modification takes effect ten (10) days in case of nonpayment of premium); and (iii) contain a waiver of subrogation in favor of Sublessor and Land Lessor. Sublessee shall not permit any insurance policy to be canceled or modified without Sublessor’s written consent unless equivalent replacement policies are issued with no lapse in coverage. All policies shall be obtained from insurance companies licensed to do business in the State of Arizona and possessing a rating of at least A – VII or higher from the A.M. Best Company, or an equivalent rating and approved by Sublessor.

(b)     Certificates of Insurance. Sublessee shall deliver a certificate of insurance for each policy required along with an endorsement naming Phoenix-Mesa Gateway Airport Authority as additional insured herein to Sublessor and Land Lessor, in standard Acord or equivalent form, prior to the Commencement Date and shall continue to provide such certificates throughout the term of this Sublease.

7.4    Property Insurance - Building, Improvements and Rental Value.

(a)    Building and Improvements. Sublessor shall obtain and keep in force a policy or policies of insurance in the name of Sublessor, with loss payable to Sublessor, any ground-lessor, and to any Lender insuring loss or damage to the Sublease Premises. The amount of such insurance shall be equal to the full insurable replacement cost of the Sublease Premises, as the same shall exist from time to time, or the amount required by any Lender, but in no event more than the commercially reasonable and available insurable value thereof. Sublessee Owned Alterations and Utility Installations, Trade Fixtures, and Sublessee's personal property shall be insured by Sublessee not by Sublessor. If the coverage is available and commercially appropriate, such policy or policies shall insure against all risks of direct physical loss or damage (except the perils of flood and/or earthquake unless required by a Lender), including coverage for debris removal and the enforcement of any Applicable Requirements requiring the upgrading, demolition, reconstruction or replacement of any portion of the Sublease Premises as the result of a covered loss. Said policy or policies shall also contain an agreed valuation provision in lieu of any coinsurance clause, waiver of subrogation. If such insurance coverage has a deductible clause, the deductible amount shall not exceed $[***] per occurrence.

(b)    Rental Value. Sublessor shall also obtain and keep in force a policy or policies in the name of Sublessor with loss payable to Sublessor and any Lender, insuring the loss of the full Rent for one year with an extended period of indemnity for an additional 180 days. Said insurance shall contain an agreed valuation provision in lieu of any coinsurance clause, and the amount of coverage shall be adjusted annually to reflect the projected Rent otherwise payable by Sublessee, for the next 12-month period.

(c)    Adjacent Premises. Sublessee shall pay for any increase in the premiums for the property insurance of the Buildings and for the Common Areas or other buildings in the Project if said increase is caused by Sublessee's acts, omissions, use or occupancy of the Sublease Premises; provided, Sublessor shall notify Sublessee in writing prior to such notification of increase and permit Sublessee a period of thirty (30) days to attempt to remedy any such omissions.

(d)    Sublessee's Improvements. Since Sublessor is the Insuring Party, Sublessor shall not be required to insure Sublessee Owned Alterations and Utility Installations unless the item in question has become the property of Sublessor under the terms of this Sublease.

7.5    Sublessee's Property; Business Interruption Insurance; Worker's Compensation Insurance.

(a)    Property Damage. Sublessee shall obtain and maintain insurance coverage on all of Sublessee's personal property, Trade Fixtures, and Sublessee Owned Alterations and Utility Installations. Such insurance shall be full replacement cost coverage with a deductible of not to exceed $[***] per occurrence. The proceeds from any such insurance shall be used by Sublessee for the replacement of personal property, Trade Fixtures and Sublessee Owned Alterations and Utility Installations.

(b)    Intentionally Omitted.

(c)    Worker's Compensation Insurance. Sublessee shall obtain and maintain Worker's Compensation Insurance in such amount as may be required by Applicable Requirements. Such policy shall include a 'Waiver of Subrogation' endorsement. Sublessee

shall provide Sublessor with a copy of such endorsement along with the certificate of insurance or copy of the policy required by this Paragraph 7.5.

(d)    No Representation of Adequate Coverage. Sublessor makes no representation that the limits or forms of coverage of insurance specified herein are adequate to cover Sublessee's property, business operations or obligations under this Sublease.

7.6    Insurance Policies. Insurance required herein shall be by companies maintaining during the policy term a "General Policyholders Rating" of at least A-, VII, as set forth in the most current issue of "Best's Insurance Guide", or such other rating as may be required by a Lender. Sublessee shall not do or permit to be done anything which invalidates the required insurance policies. Sublessee shall, prior to the Commencement Date, deliver to Sublessor certified copies of policies of such insurance or certificates with copies of the required endorsements evidencing the existence and amounts of the required insurance. No such policy shall be cancelable except after 30 days prior written notice to Sublessor. Sublessee shall, prior to the expiration of such policies, furnish Sublessor with evidence of renewals or "insurance binders" evidencing renewal thereof. If either Party shall fail to procure and maintain the insurance required to be carried by it, the other Party may, but shall not be required to, procure and maintain the same.

7.7    Waiver of Subrogation. Without affecting any other rights or remedies, Sublessee and Sublessor each hereby release and relieve the other, and waive their entire right to recover damages against the other, for loss of or damage to its property arising out of or incident to the perils required to be insured against herein. The effect of such releases and waivers is not limited by the amount of insurance carried or required, or by any deductibles applicable hereto. The Parties agree to have their respective property damage insurance carriers waive any right to subrogation that such companies may have against Sublessor or Sublessee, as the case may be, so long as the insurance is not invalidated thereby.

7.8    Indemnities. Except for Sublessor's negligence or willful misconduct and except for Sublessor’s breach of any of its obligations under this Lease, Sublessee shall indemnify, protect, defend and hold harmless the Sublease Premises, Sublessor and its agents, Sublessor's master or ground lessor, partners and Lenders, from and against any and all claims, loss of rents and/or damages, liens, judgments, penalties, attorneys' and consultants' fees, expenses and/or liabilities arising out of, involving, or in connection with, an Event of Default of this Sublease by Sublessee and/or the use and/or occupancy of the Sublease Premises and/or Project by Sublessee and/or by Sublessee's employees, contractors or invitees. If any action or proceeding is brought against Sublessor by reason of any of the foregoing matters, Sublessee shall upon notice defend the same at Sublessee's expense by counsel reasonably satisfactory to Sublessor and Sublessor shall cooperate with Sublessee in such defense. Sublessor need not have first paid any such claim in order to be defended or indemnified. Sublessor shall defend, indemnify, and hold Sublessee and its agents, officers, directors, employees, and contractors harmless against and from any and all injuries, claims, judgments, costs, expenses, liabilities, losses, damages, injunctions, suits, actions, fines, penalties, and demands of any kind or nature (including reasonable attorneys' fees) by or on behalf of any person, entity, or governmental authority occasioned by or arising out of (a) injuries occurring in the Common Areas; (b) any intentional act, or negligence of Sublessor or Sublessor's agents, employees, or independent contractors; (c) any breach or default in the performance of any obligation on Sublessor's part to be performed under this Sublease; (d) any defects in the design, workmanship or materials of the original construction of the Buildings; or (e) the failure of any representation or warranty made by Sublessor herein to be true when made. This indemnity shall survive termination of this Sublease only as to claims arising out of events that occur prior to termination of the Lease.

7.9    Exemption of Sublessor and its Agents from Liability. Except to the extent caused by the negligence or breach of this Sublease by Sublessor or its agents, neither Sublessor nor its agents shall be liable under any circumstances for: (i) injury or damage to the person or goods, wares, merchandise or other property of Sublessee, Sublessee's employees, contractors, invitees, customers, or any other person in or about the Sublease Premises, whether such damage or injury is caused by or results from fire, steam, electricity, gas, water or rain, indoor air quality, the presence of mold or from the breakage, leakage, obstruction or other defects of pipes, fire sprinklers, wires, appliances, plumbing, HVAC or lighting fixtures, or from any other cause, whether the said injury or damage results from conditions arising upon the Sublease Premises or upon other portions of the Building, or from other sources or places, (ii) any damages arising from any act or neglect of any other tenant or subtenant of Sublessor or from the failure of Sublessor or its agents to enforce the provisions of any other lease in the Project, or (iii) injury to Sublessee's business or for any loss of income or profit therefrom. Instead, except as provided above in this Paragraph 7.9, it is intended that Sublessee's sole recourse in the event of such damages or injury be to file a claim on the insurance policy(ies) that Sublessee is required to maintain pursuant to the provisions of Paragraph 7.

8.    Damage or Destruction.

8.1    Definitions.

(a)    "Sublease Premises Partial Damage" shall mean damage or destruction to the improvements on the Sublease Premises, other than Sublessee Owned Alterations and Utility Installations, which can reasonably be repaired in 15 months or less from the date of the damage or destruction. Sublessor shall notify Sublessee in writing within 15 days from the date of the damage or destruction as to whether or not the damage is Partial or Total.

(b)    "Sublease Premises Total Destruction" shall mean damage or destruction to the improvements on the Sublease Premises, other than Sublessee Owned Alterations and Utility Installations and Trade Fixtures, which cannot reasonably be repaired in 15 months or less from the date of the damage. Sublessor shall notify Sublessee in writing within 15 days from the date of the damage or destruction as to whether or not the damage is Partial or Total.

(c)    "Insured Loss" shall mean damage or destruction to improvements on the Sublease Premises, other than Sublessee Owned Alterations and Utility Installations and Trade Fixtures, which was caused by an event required to be covered by the insurance described in Paragraph 7.4(a), irrespective of any deductible amounts or coverage limits involved.

(d)    "Replacement Cost" shall mean the cost to repair or rebuild the improvements owned by Sublessor at the time of the occurrence to their condition existing immediately prior thereto, including demolition, debris removal and upgrading required by the operation of Applicable Requirements, and without deduction for depreciation.

(e)    "Hazardous Substance Condition" shall mean the occurrence or discovery of a condition involving the presence of, or a contamination by, a Hazardous Substance, in, on, or under the Sublease Premises which requires restoration.

8.2    Partial Damage - Insured Loss. If a Sublease Premises Partial Damage that is an Insured Loss occurs, then Sublessor shall, at Sublessor's expense, repair such damage (but not Sublessee's Trade Fixtures or Sublessee Owned Alterations and Utility Installations) as soon as reasonably possible and this Sublease shall continue in full force and effect; provided, however, that Sublessee shall have the right to make the repair of any damage or destruction

the total cost to repair of which is $[***] or less, and, in such event, Sublessor shall make any applicable insurance proceeds available to Sublessee on a reasonable basis for that purpose. Notwithstanding the foregoing, if the required insurance was not in force or the insurance proceeds are not sufficient to effect such repair, the Insuring Party shall promptly contribute the shortage in proceeds as and when required to complete said repairs. In the event, however, such shortage was due to the fact that, by reason of the unique nature of the improvements or full replacement cost insurance coverage was not commercially reasonable and available, Sublessor shall have no obligation to pay for the shortage in insurance proceeds or to fully restore the unique aspects of the Sublease Premises unless Sublessee provides Sublessor with the funds to cover same, or adequate assurance thereof, within 30 days following receipt of written notice of such shortage and request therefor. If Sublessor receives said funds or adequate assurance thereof within said 30-day period, the party responsible for making the repairs shall complete them as soon as reasonably possible and this Sublease shall remain in full force and effect. If such funds or assurance are not received, Sublessor may nevertheless elect by written notice to Sublessee within 10 days thereafter to: (i) make such restoration and repair as is commercially reasonable with Sublessor paying any shortage in proceeds, in which case this Sublease shall remain in full force and effect, or (ii) have this Sublease terminate 30 days thereafter. Sublease Premises Partial Damage due to flood or earthquake shall be subject to Paragraph 8.3, notwithstanding that there may be some insurance coverage, but the net proceeds of any such insurance shall be made available for the repairs if made by either Party.

8.3    Partial Damage - Uninsured Loss. If a Sublease Premises Partial Damage that is not an Insured Loss occurs, Sublessor may either: (i) repair such damage as soon as reasonably possible at Sublessor's expense (subject to reimbursement pursuant to Paragraph 4.2), in which event this Sublease shall continue in full force and effect, or (ii) terminate this Sublease by giving written notice to Sublessee within 30 days after receipt by Sublessor of knowledge of the occurrence of such damage. Such termination shall be effective 60 days following the date of such notice. In the event Sublessor elects to terminate this Lease, Sublessee shall have the right within 10 business days after receipt of the termination notice to give written notice to Sublessor of Sublessee's commitment to pay for the repair of such damage without reimbursement from Sublessor; provided, Sublessee shall receive a credit against Rent next becoming due to the extent Sublessee contributes any such funds. Sublessee shall provide Sublessor with said funds or satisfactory assurance thereof within 30 days after making such commitment. In such event this Sublease shall continue in full force and effect, and Sublessor shall proceed to make such repairs as soon as reasonably possible after the required funds are available. If Sublessee does not make the required commitment, this Sublease shall terminate as of the date specified in the termination notice.

8.4    Total Destruction. Notwithstanding any other provision hereof, if a Sublease Premises Total Destruction occurs, this Sublease shall terminate 60 days following such Destruction. If the damage or destruction was caused by the gross negligence or willful misconduct of Sublessee, Sublessor shall have the right to recover Sublessor's damages from Sublessee, except as provided in Paragraph 7.7.

8.5    Damage Near End of Term. If at any time during the last 6 months of this Sublease there is damage for which the cost to repair exceeds one month's Base Rent, whether or not an Insured Loss, Sublessor or Sublessee may terminate this Sublease effective 60 days following the date of occurrence of such damage by giving a written termination notice to the other Party within 30 days after the date of occurrence of such damage. Notwithstanding the foregoing, if Sublessee at that time has an exercisable option to extend this Sublease or to purchase the Sublease Premises, then Sublessee may preserve this Sublease by, (a) exercising such option and (b) providing Sublessor with any shortage in insurance proceeds (or adequate assurance thereof) needed to make the repairs on or before the earlier of (i) the date which is

10 days after Sublessee's receipt of Sublessor's written notice purporting to terminate this Sublease, or (ii) the day prior to the date upon which such option expires. If Sublessee duly exercises such option during such period and provides Sublessor with funds (or adequate assurance thereof) to cover any shortage in insurance proceeds, Sublessor shall, at Sublessor's commercially reasonable expense, repair such damage as soon as reasonably possible and this Sublease shall continue in full force and effect. If Sublessee fails to exercise such option and provide such funds or assurance during such period, then this Sublease shall terminate on the date specified in the termination notice and Sublessee's option(s) shall be extinguished.

8.6    Abatement of Rent; Sublessee’s Remedies.

(a)    Abatement. In the event of Sublease Premises Partial Damage or Sublease Premises Total Destruction, the Rent payable by Sublessee for the period required for the repair, remediation or restoration of such damage shall be abated in proportion to the degree to which Sublessee’s use of the Sublease Premises is impaired. All other obligations of Sublessee and Sublessor hereunder shall be performed by the applicable Party, and Sublessor shall have no liability for any such damage, destruction, remediation, repair or restoration except as provided herein.

(b)    Remedies. If Sublessor is obligated to repair or restore the Sublease Premises and does not commence, in a substantial and meaningful way, such repair or restoration within 45 days after such obligation shall accrue, Sublessee may, at any time prior to the commencement of such repair or restoration, give written notice to Sublessor and to any Lenders of which Sublessee has actual notice, of Sublessee’s election to terminate this Sublease on a date not less than 30 days following the giving of such notice. If Sublessee gives such notice and such repair or restoration is not commenced within 30 days thereafter, this Sublease shall terminate as of the date specified in said notice. If the repair or restoration is commenced within such 30 days, this Sublease shall continue in full force and effect. “Commence” shall mean either the unconditional authorization of the preparation of the required plans, or the beginning of the actual work on the Sublease Premises, whichever first occurs. If Sublessor is obligated to repair or restore the Sublease Premises and does not complete the repairs within six (6) months following the damage or casualty or Sublessor does not commence and complete the repairs with diligence, Sublessee shall have the right to terminate this Sublease.

8.7    Termination; Advance Payments. Upon termination of this Sublease pursuant to Paragraph 8, an equitable adjustment shall be made concerning advance Base Rent and any other advance payments made by Sublessee to Sublessor.

9.    Payment of Taxes. Except as otherwise provided in Paragraph 9.3, Sublessor shall pay all of the Real Property Taxes applicable to the Project, and said payments shall NOT be included in the calculation of Common Area Operating Expenses.

9.1    Additional Improvements. Common Area Operating Expenses shall not include Real Property Taxes specified in the tax assessor's records and work sheets as being caused by additional improvements placed upon the Project by other sublessees or by Sublessor for the exclusive enjoyment of such other sublessees. Notwithstanding Paragraph 9.2 hereof, Sublessee shall, however, pay to Sublessor at the time Common Area Operating Expenses are payable under Paragraph 4.2, the entirety of any increase in Real Property Taxes if assessed solely by reason of Alterations, Trade Fixtures or Utility Installations placed upon the Sublease Premises by Sublessee or at Sublessee's written request or by reason of any alterations or improvements to the Sublease Premises made by Sublessor, at the written request of Sublessee, subsequent to the execution of this Sublease by the Parties.

9.2    Joint Assessment. If the Buildings are not separately assessed, Real Property Taxes allocated to the Buildings shall be an equitable proportion of the Real Property Taxes for all of the land and improvements included within the tax parcel assessed, such proportion to be reasonably determined by Sublessor from the respective valuations assigned in the assessor's work sheets or such other information as may be reasonably available.

9.3    Personal Property Taxes. Sublessee shall pay prior to delinquency all taxes assessed against and levied upon Sublessee Owned Alterations and Utility Installations, Trade Fixtures, furnishings, equipment and all personal property of Sublessee contained in the Sublease Premises. When possible, Sublessee shall cause its Sublessee Owned Alterations and Utility Installations, Trade Fixtures, furnishings, equipment and all other personal property to be assessed and billed separately from the real property of Sublessor. If any of Sublessee's said property shall be assessed with Sublessor's real property, Sublessee shall pay Sublessor the taxes attributable to Sublessee's property within 30 days after receipt of a written statement setting forth the taxes applicable to Sublessee's property.

10.    Utilities and Services. Sublessee shall pay for all water, gas, heat, light, power, telephone, trash disposal and other utilities and services supplied to the Sublease Premises, together with any taxes thereon. There shall be no abatement of Rent and Sublessor shall not be liable in any respect whatsoever for the inadequacy, stoppage, interruption or discontinuance of any utility or service due to riot, strike, labor dispute, breakdown, accident, repair or other cause beyond Sublessor's reasonable control or in cooperation with governmental request or directions. Provided no Event of Default has then occurred and be continuing under this Sublease, if electrical power or HVAC are interrupted due to the negligence or willful misconduct of Sublessor or its employees or agents (a “Utility Interruption”), and Sublessee is unable to carry on its business in a reasonably normal manner due to the failure of any of such utilities and services, and vacates all or the affected portion of the Sublease Premises for a period in excess of five (5) consecutive days, or a cumulative total of ten (10) days in any calendar year, the Base Rent and Common Area Operating Expenses payable under this Sublease shall be abated retroactively from the first (1st) day of the Utility Interruption (in proportion to the area of the Sublease Premises vacated by Sublessee by reason of such failure, if less than all of the Sublease Premises were affected) and for as long as such inability to carry on Sublessee’s business continued, until such time as the service is restored or Sublessee reoccupies the Buildings or affected portion thereof, whichever is earlier.  In the event of any curtailment, diminution, or failure with respect to utilities and services in the Sublease Premises, Sublessor shall use due diligence to restore full service.

Within thirty (30) days of Sublessor's written request, Sublessee agrees to deliver to Sublessor such information, documents and/or authorization as Sublessor reasonably needs in order to comply with new or existing Applicable Requirements relating to commercial building energy usage, ratings, and/or the reporting thereof.

11.    Assignment and Subletting.

11.1    Sublessor's and Land Lessor’s Consent Required.

(a)    Sublessee shall not voluntarily or by operation of law assign, transfer, mortgage or encumber (collectively, "assign or assignment") or sublet all or any part of Sublessee's interest in this Sublease or in the Sublease Premises without Sublessor's prior written consent, not to be unreasonably withheld, conditioned or delayed.

(b)    Unless Sublessee is a corporation and its stock is publicly traded on a national stock exchange, a change in the control of Sublessee shall constitute an assignment requiring consent. The transfer, on a cumulative basis, of 25% or more of the voting control of

Sublessee shall constitute a change in control for this purpose. The parties acknowledge and agree that Sublessee is a publicly traded corporation on a national exchange and the provisions of this subparagraph (b) shall not be applicable to the original Sublessee.

(c)    Intentionally Omitted.

(d)    An assignment or subletting without consent shall be an Event of Default if not cured as set forth in Section 11 of the Land Lease, as incorporated herein by Paragraph 12 of this Sublease.

(e)    Sublessee's remedy for any breach of Paragraph 11.1 by Sublessor shall be limited to compensatory damages and/or injunctive relief.

(f)    Sublessor may reasonably withhold consent to a proposed assignment or subletting if there has occurred and is continuing an Event of Default under this Sublease at the time consent is requested.

(g)    Notwithstanding the foregoing, allowing a de minimis portion of the Sublease Premises, i.e., 10,000 square feet or less, to be used by a third party vendor shall not constitute a subletting.

(h) Land Lessor’s prior written consent shall be required for any assignment or sublet of the Sublease Premises.

11.2    Terms and Conditions Applicable to Assignment and Subletting.

(a)    Regardless of Sublessor's consent, no assignment or subletting shall : (i) be effective without the express written assumption by an assignee of the obligations of Sublessee under this Sublease (and any subtenant shall agree to comply with the terms of this Sublease), (ii) release Sublessee of any obligations hereunder, or (iii) alter the primary liability of Sublessee for the payment of Rent or for the performance of any other obligations to be performed by Sublessee.

(b)    Sublessor may accept Rent or performance of Sublessee's obligations from any person other than Sublessee pending approval or disapproval of an assignment. Neither a delay in the approval or disapproval of such assignment nor the acceptance of Rent or performance shall constitute a waiver or estoppel of Sublessor's right to exercise its remedies for an Event of Default by Sublessee.

(c)    Sublessor's consent to any assignment or subletting shall not constitute a consent to any subsequent assignment or subletting.

(d)    Upon the occurrence and during the continuance of an Event of Default by Sublessee, Sublessor may proceed directly against Sublessee or anyone else responsible for the performance of Sublessee's obligations under this Sublease, including any assignee or sublessee, without first exhausting Sublessor's remedies against any other person or entity responsible therefor to Sublessor, or any security held by Sublessor.

(e)    Each request for consent to an assignment or subletting shall be in writing, accompanied by information relevant to Sublessor's determination as to the financial and operational responsibility and appropriateness of the proposed assignee or sublessee, including but not limited to the intended use and/or required modification of the Sublease Premises, if any, together with a fee of $[***] as consideration for Sublessor's considering and

processing said request. Sublessee agrees to provide Sublessor with such other or additional information and/or documentation as may be reasonably requested. (See also Paragraph 35)

(f)    Any assignee of this Sublease shall, by reason of accepting such assignment be deemed to have assumed and agreed to conform and comply with each and every term, covenant, condition and obligation herein to be observed or performed by Sublessee during the term of said assignment, other than such obligations as are contrary to or inconsistent with provisions of an assignment to which Sublessor has specifically consented to in writing.

(g)    Sublessor's consent to any assignment or subletting shall not transfer to the assignee or sublessee any Option granted to the original Sublessee by this Sublease unless such transfer is specifically consented to by Sublessor in writing. (See Paragraph 38.2)

11.3    Additional Terms and Conditions. The following terms and conditions shall apply to any subletting by Sublessee of all or any part of the Sublease Premises and shall be deemed included in all subleases under this Sublease whether or not expressly incorporated therein:

(a)    Sublessee shall have the right to sublease or assign any portion of the Buildings to any related entity, parent company, subsidiary or affiliate, or to a successor by merger or purchase (a “Sublessee Affiliate”) without Sublessor’s written consent, but subject to the consent of Land Lessor. Sublessee shall have the right to sublease or assign any portion of the Sublease Premises to any other assignee/subtenant with Sublessor’s written consent, which shall not be unreasonably withheld, conditioned, or delayed, and delivered within fifteen (15) business days of receipt of notice. Sublessee’s right to sublease is also subject to the written consent of Land Lessor. Sublessor shall have no right of recapture. In the event Sublessor does not consent to an assignment or subletting, Sublessor shall state in specific detail the reasons therefor.

(b)    Sublessor shall be entitled to share in fifty percent (50%) of the Net Profits attributable to any sublease or assignment. “Net Profits” shall be defined as the net rent (sublease rent compared with contract rent under this Sublease) received from the subtenant reduced by all typical subleasing costs, such as rent and other concessions, tenant improvements, broker commissions and bonuses, legal fees, other subleasing costs and downtime – the time the space is vacant and listed for sublease by a local commercial real estate broker, such typical subleasing costs to be amortized over the term of the sublease or remaining Term of this Sublease if an assignment.

(c)     Sublessee hereby assigns and transfers to Sublessor all of Sublessee’s interest in all Rent payable on any sublease, and Sublessor may collect such Rent and apply same toward Sublessee’s obligations under this Sublease; provided, however, that until an Event of Default shall occur in the performance of Sublessee’s obligations, Sublessee may collect said Rent. In the event that the amount collected by Sublessor exceeds Sublessee’s then outstanding obligations any such excess shall be refunded to Sublessee. Sublessor shall not, by reason of the foregoing or any assignment of such sublease, nor by reason of the collection of Rent, be deemed liable to the sublessee for any failure of Sublessee to perform and comply with any of Sublessee’s obligations to such sublessee. Sublessee hereby irrevocably authorizes and directs any such sublessee, upon receipt of a written notice from Sublessor stating that an Event of Default in then continuing, to pay to Sublessor all Rent due and to become due under the sublease. Sublessee shall rely upon any such notice from Sublessor and shall pay all Rents to Sublessor without any obligation or right to inquire as to whether such Event of Default is then continuing, notwithstanding any claim from Sublessee to the contrary.

(d)    Upon the occurrence and during the continuance of an Event of Default, Sublessor may, at its option, require sublessee to attorn to Sublessor, in which event Sublessor shall undertake the obligations of the sublessor under such sublease from the time of the exercise of said option to the expiration of such sublease; provided, however, Sublessor shall not be liable for any prepaid rents or security deposit paid by such sublessee to such sublessor or for any prior defaults or breaches of such sublessor.

(e)    Any matter requiring the consent of the sublessor under a sublease shall also require the consent of Sublessor.

(f)    No sublessee shall further assign or sublet all or any part of the Sublease Premises without Sublessor's prior written consent. Sublessor shall deliver a copy of any notice of an Event of Default by Sublessee to the sublessee, who shall have the right to cure the Event of Default of Sublessee within the grace period, if any, specified in such notice. The sublessee shall have a right of reimbursement and offset from and against Sublessee for any such Events of Default cured by the sublessee.

12.    Event of Default; Remedies.

12.1    Event of Default. The terms and provisions of Sections 11.1 through 11.9 of the Land Lease are incorporated herein by this reference such that the term “Lease” used in such sections shall mean this Sublease, the term “Lessee” shall mean Sublessee, the term “Lessor” shall mean Sublessor, the term “Transfer” shall mean an assignment or subletting by Sublessee, the term “Term” shall mean the Term of this Sublease, the term “Premises” shall mean the Sublease Premises and the term “Base Rent” shall mean the Base Rent payable by Sublessee under this Sublease.

12.2     Intentionally Omitted.

12.3    Inducement Recapture. Any agreement for free or abated Base Rent or Common Area Operating Expenses, all of which concessions are hereinafter referred to as "Inducement Provisions," shall be deemed conditioned upon Sublessee's full and faithful performance of all of the terms, covenants and conditions of this Sublease. Upon the occurrence and during the continuance of an Event of Default, a portion of such abated or free Base Rent and Common Area Operating Expenses in an amount equal to the then unamortized amount of free Base Rent and Common Area Operating Expenses shall be immediately due and payable by Sublessee to Sublessor (for example, in the event the Term of this Sublease is ten (10) years and an Event of Default of this Sublease occurs on the last day of the sixtieth (60th) month of the Term, Sublessee shall be obligated to pay an amount equal to fifty percent (50%) of any free Base Rent and Common Area Operating Expenses provided to Sublessee). The acceptance by Sublessor of rent or the cure of an Event of Default which initiated the operation of this paragraph shall not be deemed a waiver by Sublessor of the provisions of this paragraph unless specifically so stated in writing by Sublessor at the time of such acceptance.

12.4     Late Charges. Sublessee hereby acknowledges that late payment by Sublessee of Rent will cause Sublessor to incur costs not contemplated by this Sublease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges, and late charges which may be imposed upon Sublessor by any Lender. Accordingly, if any Rent shall not be received by Sublessor within 10 days after such amount shall be due, then, without any requirement for notice to Sublessee, Sublessee shall immediately pay to Sublessor a one-time late charge equal to 2% of each such overdue amount or $[***], whichever is greater; provided, no such late charge shall be payable in the event Sublessee pays such overdue amount within five (5) business days following written notice to Sublessee. The parties hereby agree that such late charge represents a fair and

reasonable estimate of the costs Sublessor will incur by reason of such late payment. Acceptance of such late charge by Sublessor shall in no event constitute a waiver of Sublessee's Event of Default with respect to such overdue amount, nor prevent the exercise of any of the other rights and remedies granted hereunder. In the event that a late charge is payable hereunder, whether or not collected, for 3 consecutive installments of Base Rent, then notwithstanding any provision of this Sublease to the contrary, Base Rent shall, at Sublessor's option, become due and payable quarterly in advance. Notwithstanding anything in this Paragraph 12.4 to the contrary, in the event Land Lessor shall become the “Sublessor” hereunder, the terms of the Land Lease shall govern and control the payment of any late charges by Sublessee.

12.5    Interest. Any monetary payment due Sublessor hereunder, other than late charges, not received by Sublessor, when due shall bear interest from and after the 31st day after it was due. The interest ("Interest") charged shall be computed at the rate of 10% per annum but shall not exceed the maximum rate allowed by law. Interest is payable in addition to the potential late charge provided for in Paragraph 12.4.

12.6    Breach by Sublessor.

(a)    Notice of Breach. Sublessor shall not be deemed in breach of this Sublease unless Sublessor fails within a reasonable time to perform an obligation required to be performed by Sublessor. For purposes of this Paragraph, a reasonable time shall in no event be less than 30 days after receipt by Sublessor, and any Lender whose name and address shall have been furnished to Sublessee in writing for such purpose, of written notice specifying wherein such obligation of Sublessor has not been performed; provided, however, that if the nature of Sublessor's obligation is such that more than 30 days are reasonably required for its performance, then Sublessor shall not be in breach if performance is commenced within such 30 day period and thereafter diligently pursued to completion.

(b)    Performance by Sublessee on Behalf of Sublessor. In the event that neither Sublessor nor Lender cures said breach within 30 days after receipt of said notice, or if having commenced said cure they do not diligently pursue it to completion or if the breach is of an emergency nature and is not cured within five (5) days following written notice from Sublessee, then Sublessee may elect to cure said breach at Sublessee's expense and offset from Rent the actual and reasonable cost to perform such cure. Sublessee shall document the cost of said cure and supply said documentation to Sublessor.

13.    Condemnation. If the Sublease Premises or any portion thereof are taken under the power of eminent domain or sold under the threat of the exercise of said power (collectively "Condemnation"), this Sublease shall terminate as to the part taken as of the date the condemning authority takes title or possession, whichever first occurs. If more than 10% of the floor area of a Hangar, or more than 25% of the parking spaces is taken by Condemnation, Sublessee may, at Sublessee's option, to be exercised in writing within 30 days after Sublessor shall have given Sublessee written notice of such taking (or in the absence of such notice, within 30 days after the condemning authority shall have taken possession) terminate this Sublease as of the date the condemning authority takes such possession. If Sublessee does not terminate this Sublease in accordance with the foregoing, this Sublease shall remain in full force and effect as to the portion of the Sublease Premises remaining, except that the Base Rent shall be reduced in proportion to the reduction in utility of the Sublease Premises caused by such Condemnation. Condemnation awards and/or payments shall be the property of Sublessor, whether such award shall be made as compensation for diminution in value of the leasehold, the value of the part taken, or for severance damages; provided, however, that Sublessee shall be entitled to any compensation paid by the condemnor for Sublessee's relocation expenses, bonus value of this Sublease, loss of business goodwill and/or Trade

Fixtures, without regard to whether or not this Sublease is terminated pursuant to the provisions of this Paragraph. All Alterations and Utility Installations made to the Sublease Premises by Sublessee, for purposes of Condemnation only, shall be considered the property of the Sublessee and Sublessee shall be entitled to any and all compensation which is payable therefor. In the event that this Sublease is not terminated by reason of the Condemnation, Sublessor shall repair any damage to the Sublease Premises caused by such Condemnation.

14.    Brokerage Fees.

14.1    Additional Commission. In addition to the payments owed pursuant to Paragraph 1.7 above, Sublessor agrees that: (a) if Sublessee exercises any Option, (b) if Sublessee or anyone affiliated with Sublessee acquires from Sublessor any rights to the Sublease Premises or other premises owned by Sublessor or leased by Sublessor and located within the Project, (c) if Sublessee remains in possession of the Sublease Premises, with the consent of Sublessor, after the expiration of this Sublease, or (d) if Base Rent is increased, whether by agreement or operation of an escalation clause herein, then, Sublessor shall pay Brokers a fee in accordance with the fee schedule of the Brokers in effect at the time this Sublease was executed. The provisions of this paragraph are intended to supersede the provisions of any earlier agreement to the contrary.

14.2    Assumption of Obligations. Any buyer or transferee of Sublessor's interest in this Sublease shall be deemed to have assumed Sublessor's obligation hereunder. Brokers shall be third party beneficiaries of the provisions of Paragraphs 1.10, 14, 21 and 30. If Sublessor fails to pay to Brokers any amounts due as and for brokerage fees pertaining to this Sublease when due, then such amounts shall accrue Interest. In addition, if Sublessor fails to pay any amounts to Sublessee's Broker when due, Sublessee's Broker may send written notice to Sublessor and Sublessee of such failure and if Sublessor fails to pay such amounts within 10 days after said notice, Sublessee shall pay said monies to its Broker and offset such amounts against Rent. In addition, Sublessee's Broker shall be deemed to be a third party beneficiary of any commission agreement entered into by and/or between Sublessor and Sublessor's Broker for the limited purpose of collecting any brokerage fee owed.

14.3    Representations and Indemnities of Broker Relationships. Sublessee and Sublessor each represent and warrant to the other that it has had no dealings with any person, firm, broker, agent or finder (other than the Brokers and Agents, if any) in connection with this Sublease, and that no one other than said named Brokers and Agents is entitled to any commission or finder's fee in connection herewith. Sublessee and Sublessor do each hereby agree to indemnify, protect, defend and hold the other harmless from and against liability for compensation or charges which may be claimed by any such unnamed broker, finder or other similar party by reason of any dealings or actions of the indemnifying Party, including any costs, expenses, attorneys' fees reasonably incurred with respect thereto.

15.    Estoppel Certificates.

(a)    Each Party (as "Responding Party") shall within 10 business days after written notice from the other Party (the "Requesting Party") execute, acknowledge and deliver to the Requesting Party a statement in writing in form similar to the then most current "Estoppel Certificate" form published by AIR CRE, plus such additional information, confirmation and/or statements as may be reasonably requested by the Requesting Party. For purposes of this Paragraph 15, Sublessee shall comply with any request made by Land Lessor under the Land Lease for an estoppel certificate and such compliance by Sublessee shall be in accordance with the terms of the Land Lease.

(b)    If the Responding Party shall fail to execute or deliver the Estoppel Certificate within such 10 day period, the Requesting Party may execute an Estoppel Certificate stating that: (i) the Sublease is in full force and effect without modification except as may be represented by the Requesting Party, (ii) there are no uncured defaults, breaches or Events of Default in the Requesting Party's performance, and (iii) if Sublessor is the Requesting Party, not more than one month's rent has been paid in advance. Prospective purchasers and encumbrancers may rely upon the Requesting Party's Estoppel Certificate, and the Responding Party shall be estopped from denying the truth of the facts contained in said Certificate.

(c)    If Sublessor desires to finance, refinance, or sell the Sublease Premises, or any part thereof, Sublessee shall within 30 days after written notice from Sublessor deliver to any potential lender or purchaser designated by Sublessor such financial statements as may be reasonably required by such lender or purchaser, including but not limited to Sublessee's financial statements for the past 3 years. All such financial statements shall be received by Sublessor and such lender or purchaser in confidence and shall be used only for the purposes herein set forth. This subparagraph (c) shall not be applicable to any entity whose common stock is traded on a national stock exchange.

16.    Definition of Sublessor. The term "Sublessor" as used herein shall mean the owner or owners at the time in question of the fee title to the Sublease Premises, or, if this is a sublease, of the “Lessee’s” interest in the Land Lease. Upon transfer or assignment and delivery of any security deposit, the prior Sublessor shall be relieved of all liability with respect to the obligations and/or covenants under this Sublease thereafter to be performed by the Sublessor but not any liability which may have accrued prior to such transfer. Subject to the foregoing, the obligations and/or covenants in this Sublease to be performed by the Sublessor shall be binding only upon the Sublessor as hereinabove defined.

17.    Severability. The invalidity of any provision of this Sublease, as determined by a court of competent jurisdiction, shall in no way affect the validity of any other provision hereof.

18.    Days. Unless otherwise specifically indicated to the contrary, the word "days” as used in this Sublease shall mean and refer to calendar days.

19.    Limitation on Liability. The obligations of a Party under this Sublease shall not constitute personal obligations of such Party, or its partners, members, directors, officers or shareholders, and Sublessee shall look to the Sublease Premises, and to no other assets of Sublessor, for the satisfaction of any liability of Sublessor with respect to this Sublease, and shall not seek recourse against Sublessor's partners, members, directors, officers or shareholders, or any of their personal assets for such satisfaction.

20.    Time of Essence. Time is of the essence with respect to the performance of all obligations to be performed or observed by the Parties under this Sublease.

21.    No Prior or Other Agreements; Broker Disclaimer. This Sublease contains all agreements between the Parties with respect to any matter mentioned herein, and no other prior or contemporaneous agreement or understanding shall be effective. Brokers have no responsibility with respect to the condition of the Sublease Premises or with respect to any default or breach hereof by either Party.

22.    Notices.

22.1    Notice Requirements. Except as provided in Paragraph 22.3 below, all notices required or permitted by this Sublease or applicable law shall be in writing and may be delivered in person (by hand or by courier) or may be sent by nationally recognized overnight

courier, regular, certified or registered mail or U.S. Postal Service Express Mail, with postage prepaid, or by facsimile transmission, or by email, and shall be deemed sufficiently given if served in a manner specified in this Paragraph 22. The addresses noted adjacent to a Party's signature on this Sublease shall be that Party's address for delivery or mailing of notices. Either Party may by written notice to the other specify a different address for notice. A copy of all notices to Sublessor shall be concurrently transmitted to such party or parties at such addresses as Sublessor may from time to time hereafter designate in writing. Sublessee’s Notice address is as follows:

22.2    Date of Notice. Any notice sent by registered or certified mail, return receipt requested, shall be deemed given on the date of delivery shown on the receipt card, or if no delivery date is shown, the postmark thereon. If sent by regular mail the notice shall be deemed given 72 hours after the same is addressed as required herein and mailed with postage prepaid. Notices delivered by United States Express Mail or overnight courier that guarantees next day delivery shall be deemed given 24 hours after delivery of the same to the Postal Service or courier. Notices delivered by hand, or transmitted by facsimile transmission or by email shall be deemed delivered upon written confirmation by the receiving Party of actual receipt.

23.    Waivers.

(a)    No waiver by Sublessor of an Event of Default by Sublessee shall be deemed a waiver of any other term, covenant or condition hereof, or of any subsequent Event of Default by Sublessee of the same or of any other term, covenant or condition hereof. Sublessor's consent to, or approval of, any act shall not be deemed to render unnecessary the obtaining of Sublessor's consent to, or approval of, any subsequent or similar act by Sublessee, or be construed as the basis of an estoppel to enforce the provision or provisions of this Sublease requiring such consent.

(b)    The acceptance of Rent by Sublessor shall not be a waiver of any Event of Default by Sublessee. Any payment by Sublessee may be accepted by Sublessor on account of monies or damages due Sublessor, notwithstanding any qualifying statements or conditions made by Sublessee in connection therewith, which such statements and/or conditions shall be of no force or effect whatsoever unless specifically agreed to in writing by Sublessor at or before the time of deposit of such payment.

(c)    THE PARTIES AGREE THAT THE TERMS OF THIS SUBLEASE SHALL GOVERN WITH REGARD TO ALL MATTERS RELATED THERETO AND HEREBY WAIVE THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE TO THE EXTENT THAT SUCH STATUTE IS INCONSISTENT WITH THIS SUBLEASE.

24.    Intentionally Omitted.

25.    No Right To Holdover. Sublessee shall have the right to holdover the Sublease Premises on a daily basis for up to six (6) months after expiration of this Sublease without Sublessor’s consent by notifying Sublessor in writing no earlier than nine (9) months and no later than six

(6) months prior to expiration of the term, as it may be extended. Except as set forth above, Sublessee has no right to retain possession of the Sublease Premises or any part thereof beyond the expiration or termination of this Sublease. In the event that Sublessee holds over, then the Base Rent shall be increased to 150% of the Base Rent applicable immediately preceding the expiration or termination. Holdover Base Rent shall be calculated on monthly basis. Nothing contained herein shall be construed as consent by Sublessor to any holding over by Sublessee. Notwithstanding anything to the contrary contained in this Paragraph 25, the terms of the Land Lease shall govern and control any holdover by Sublessee.

26.    Cumulative Remedies. No remedy or election hereunder shall be deemed exclusive but shall, wherever possible, be cumulative with all other remedies at law or in equity.

27.    Covenants and Conditions; Construction of Agreement. All provisions of this Sublease to be observed or performed by Sublessee are both covenants and conditions. In construing this Sublease, all headings and titles are for the convenience of the Parties only and shall not be considered a part of this Sublease. Whenever required by the context, the singular shall include the plural and vice versa. This Sublease shall not be construed as if prepared by one of the Parties, but rather according to its fair meaning as a whole, as if both Parties had prepared it.

28.    Binding Effect; Choice of Law. This Sublease shall be binding upon the Parties, their personal representatives, successors and assigns and be governed by the laws of the State in which the Sublease Premises are located. Any litigation between the Parties hereto concerning this Sublease shall be initiated in the county in which the Sublease Premises are located. Signatures to this Sublease accomplished by means of electronic signature or similar technology shall be legal and binding.

29.    Subordination; Attornment; Non-Disturbance.

29.1    Subordination. Subject to the terms and conditions of this Sublease, this Sublease and any Option granted hereby shall be subject and subordinate to any ground lease (including without limitation, the Land Lease (including without limitation, the Airport Rules and Regulations, the Airport Minimum Standards (as defined in the Land Lease) and the terms and conditions described in Section 9.6 of the Land Lease under which Phoenix-Mesa Gateway Airport Authority acquired the Project), mortgage, deed of trust, or other hypothecation or security device (collectively, "Security Device"), now or hereafter placed upon the Sublease Premises, to any and all advances made on the security thereof, and to all renewals, modifications, and extensions thereof. Sublessee agrees that the holders of any such Security Devices (in this Sublease together referred to as "Lender") shall have no liability or obligation to perform any of the obligations of Sublessor under this Sublease unless and until such Lender is the Sublessor under this Sublease. Any Lender may elect to have this Sublease and/or any Option granted hereby superior to the lien of its Security Device by giving written notice thereof to Sublessee, whereupon this Sublease and such Options shall be deemed prior to such Security Device, notwithstanding the relative dates of the documentation or recordation thereof.

29.2    Attornment. In the event that Sublessor transfers title to the Premises, or the Sublease Premises are acquired by another upon the foreclosure or termination of a Security Device to which this Sublease is subordinated (i) Sublessee shall, subject to the non-disturbance provisions of Paragraph 29.3, attorn to such new owner, and upon request, enter into a new lease, containing all of the terms and provisions of this Sublease, with such new owner for the remainder of the term hereof, or, at the election of the new owner, this Sublease will automatically become a new sublease between Sublessee and such new owner, and (ii) Sublessor shall thereafter be relieved of any further obligations hereunder and such

new owner shall assume all of Sublessor's obligations, except that such new owner shall not: (a) be liable for any act or omission of any prior sublessor or with respect to events occurring prior to acquisition of ownership; (b) be subject to any offsets or defenses which Sublessee might have against any prior sublessor, (c) be bound by prepayment of more than one month's rent, or (d) be liable for the return of any security deposit paid to any prior sublessor which was not paid or credited to such new owner. Sublessee shall make no prepayment of Rent (as defined in Paragraph 4.1) in excess of one (1) month in advance.

29.3    Non-Disturbance. With respect to any Security Devices currently encumbering the Sublease Premises and with respect to any Security Devices entered into by Sublessor after the execution of this Sublease, Sublessee's subordination of this Sublease shall be subject to receiving a commercially reasonable non-disturbance agreement (a "Non-Disturbance Agreement") from the Lender which Non-Disturbance Agreement provides that Sublessee's possession of the Sublease Premises, and this Sublease, including any options to extend the term hereof, will not be disturbed so long as there has not occurred and is continuing an Event of Default by Sublessee and attorns to the record owner or sublessor of the Sublease Premises. Execution and delivery of such Non-Disturbance Agreement (in recordable form, with notary acknowledgements) from each Lender currently encumbering the Sublease Premises, Sublessor and Sublessee shall be a condition to the effectiveness of this Sublease. Sublessor represents and warrants to Sublessee that, as of the date of this Sublease set forth in Paragraph 1.1, there are no Security Devices encumbering the Sublease Premises except a construction loan obtained by Sublessor. In the event a Non-Disturbance Agreement is not provided to Sublessee by such Security Device holder, and executed, notarized and delivered by all parties thereto, within thirty (30) days after the date of this Sublease, Sublessee shall have the right to terminate this Sublease.

29.4    Self-Executing. The agreements contained in this Paragraph 29 shall be effective without the execution of any further documents; provided, however, that, upon written request from Sublessor or a Lender in connection with a sale, financing or refinancing of the Sublease Premises, Sublessee and Sublessor shall execute such further writings as may be reasonably required to separately document any subordination, attornment and/or Non-Disturbance Agreement provided for herein.

30.    Attorneys' Fees. If any Party or Broker brings an action or proceeding involving the Sublease Premises whether founded in tort, contract or equity, or to declare rights hereunder, the Prevailing Party (as hereafter defined) in any such proceeding, action, or appeal thereon, shall be entitled to reasonable attorneys' fees. Such fees may be awarded in the same suit or recovered in a separate suit, whether or not such action or proceeding is pursued to decision or judgment. The term, "Prevailing Party" shall include, without limitation, a Party or Broker who substantially obtains or defeats the relief sought, as the case may be, whether by compromise, settlement, judgment, or the abandonment by the other Party or Broker of its claim or defense. The attorneys' fees award shall not be computed in accordance with any court fee schedule, but shall be such as to fully reimburse all attorneys' fees reasonably incurred.

31.    Intentionally Omitted.

32.    Auctions. Sublessee shall not conduct, nor permit to be conducted, any auction upon the Sublease Premises without Sublessor's prior written consent. Sublessor shall not be obligated to exercise any standard of reasonableness in determining whether to permit an auction.

33.    Signs. Sublessor may place on the Sublease Premises ordinary "For Sale" signs at any time and ordinary "For Lease" signs during the last 6 months of the term hereof. All signs must

comply with all Applicable Requirements and are subject to the terms and conditions of the Land Lease with respect to signage. Sublessor grants Sublessee the exclusive right to place its illuminated, if desired, corporate identity anywhere on the interior/exterior of the Buildings, including the roof structure to be visible to flying aircraft. In addition, Sublessee shall be granted reasonable directional signs, to the Sublease Premises, within the Project. All signage shall be pursuant to local sign ordinances from the jurisdiction providing any approvals/permits for exterior Building/Project signage permits, and the Airport Authority, if required. All signage shall be subject to Sublessor’s approval, not to be unreasonably withheld, conditioned or delayed, and Land Lessor’s approval.

34.    Termination; Merger. Unless specifically stated otherwise in writing by Sublessor, the voluntary or other surrender of this Sublease by Sublessee, the mutual termination or cancellation hereof, or a termination hereof by Sublessor as a result of an Event of Default by Sublessee, shall automatically terminate any sublease or lesser estate in the Sublease Premises; provided, however, that Sublessor may elect to continue any one or all existing subtenancies. Sublessor's failure within 10 days following any such event to elect to the contrary by written notice to the holder of any such lesser interest, shall constitute Sublessor’s election to have such event constitute the termination of such interest.

35.    Consents. All requests for consent shall be in writing. Except as otherwise provided herein, wherever in this Sublease the consent of a Party is required to an act by or for the other Party, such consent shall not be unreasonably withheld, conditioned or delayed. Sublessor's actual reasonable costs and expenses (including but not limited to reasonable and actual architects', attorneys', engineers' and other consultants' fees) incurred in the consideration of, or response to, a request by Sublessee for any Sublessor consent, including but not limited to consents to an assignment, a subletting or the presence or use of a Hazardous Substance, shall be paid by Sublessee upon receipt of an invoice and supporting documentation therefor. Sublessor's consent to any act, assignment or subletting shall not constitute an acknowledgment that no Event of Default by Sublessee of this Sublease exists, nor shall such consent be deemed a waiver of any then existing Event of Default, except as may be otherwise specifically stated in writing by Sublessor at the time of such consent. The failure to specify herein any particular condition to Sublessor's consent shall not preclude the imposition by Sublessor at the time of consent of such further or other conditions as are then reasonable with reference to the particular matter for which consent is being given. In the event that either Party disagrees with any determination made by the other hereunder and reasonably requests the reasons for such determination, the determining party shall furnish its reasons in writing and in reasonable detail within 10 business days following such request.

36.    Guarantor. Intentionally Omitted.

37.    Quiet Possession. Subject to payment by Sublessee of the Rent and performance of all of the covenants, conditions and provisions on Sublessee's part to be observed and performed under this Lease, Sublessee shall have quiet possession and quiet enjoyment of the Sublease Premises during the Term hereof, as such Term may be extended.
