5.7    Accord and Satisfaction. No payment by Tenant or receipt by Landlord of an amount less than is due hereunder shall be deemed to be other than payment towards or on account of the earliest portion of the amount then due by Tenant nor shall any endorsement or statement on any check or payment (or in any letter accompanying any check or payment) be deemed an accord and satisfaction (or payment in full), and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such amount or pursue any other remedy provided herein or otherwise available at law or in equity.

In addition, Landlord may condition its consent to the making of any Alteration upon the removal of such Alteration prior to the end of the Lease Term. Any Alterations made by Tenant, whether Landlord’s consent is required or not, shall be made with reasonable diligence and be done in a good and workmanlike manner and in accordance with all applicable Laws.

10.3    Removal of Alterations and Tenant Improvements. All Alterations and Tenant Improvements made by Tenant at its expense (including, but not limited to, business and trade

-21-

fixtures, utility installations, machinery, equipment, furniture, movable partitions and items of personal property), shall be and remain the property of Tenant and shall be removed from the Premises prior to the Expiration Date, unless and to the extent the Parties agree in writing to the contrary. At any time during the Lease Term and upon expiration or earlier termination of this Lease, Tenant may, at its sole expense, remove any or all such items; provided, that Tenant repairs any damage to the Premises or Building caused by such removal in a good and workmanlike manner and provided that, after giving effect to such removal, the remaining Equipment remains in good operating order for its intended use (unless Tenant has acquired the Equipment from Landlord). Unless Tenant has acquired the Equipment from Landlord, Tenant shall not remove any of the Equipment unless the same is being replaced by new equipment of equal or greater value and utility; provided Tenant may remove Tenant Equipment. If Tenant fails to remove any and all Alterations and Tenant Improvements as required herein, then the same shall become, at the sole option of Landlord, the property of Landlord at the end of the Lease Term. If Landlord does not elect to assume ownership of Tenant's Alterations, Tenant Improvements, trade fixtures and personal property as aforesaid, then Landlord shall have the right to have the same removed and sold, stored or otherwise disposed of and the Premises repaired and Tenant shall reimburse Landlord for the cost thereof plus an administrative fee of five percent (5%) of such costs. The provisions of this paragraph shall survive the termination or expiration of this Lease. Any items of Tenant’s personal property may be deemed, at the option of Landlord, to have been abandoned if left in the Premises or at the Property after the Abandonment Deadline, and in such case such items may be retained by Landlord, without accountability, in such a commercially reasonable manner as Landlord shall determine at Tenant’s expense; subject however, to the provisions and requirements of any applicable Law relating to abandoned property in a leasehold. The “Abandonment Deadline” means the earlier of the expiration date of this Lease, or ten (10) Business Days following an earlier termination date, or three (3) Business Days following entry of an order of possession for restoration of the Premises to Landlord.

10.4    Lien. Tenant covenants that it will not suffer or permit any liens to be filed against the Landlord’s title to the Premises or against Tenant’s leasehold interest in the Premises as a result of nonpayment for, or disputes with respect to, any work, labor, services or materials supplied to Tenant or as a result of an agreement with, or the assent of Tenant, including, without limitation, the Tenant Improvements. If any such lien shall be filed at any time against the Premises or any part thereof, Tenant shall, within twenty (20) days after receipt of written notice of such lien (or such shorter period as may be required under any Mortgage), cause the same to be discharged of record or bonded over as may be necessary to prevent a foreclosure on the Premises or any part thereof. No consent or approval granted by Landlord with respect to any Alterations shall be deemed to imply a consent on the part of Landlord to the filing of any lien against Landlord’s interest in the Premises. Tenant shall indemnify, defend (by counsel acceptable to Landlord) and hold harmless all of the Landlord Indemnified Parties from and against any and all claims, causes of action, suits, arbitration proceedings, losses, damages, judgments, settlements, penalties and expenses (including, without limitation, reasonable attorneys’ fees and expenses, court costs, expert witness fees and expenses and other dispute resolution expenses) suffered or incurred by any one or more of the Landlord Indemnified Parties resulting from the failure of any contractor or subcontractor at any tier to be paid any amounts claimed relative to any Tenant Improvements, Alterations or Tenant Repairs, including, without limitation, any such claims of liens which may be asserted against the Premises or any portion thereof.

10.5    Landlord's Right to Inspect and Repair. Landlord and its authorized officers, employees, agents and contractors shall have the right (during normal business hours, or at any time in the case of an emergency, and with as little interruption to the operations of Tenant as is reasonably

-22-

practicable) to enter upon the Premises for the following purposes: (a) to inspect the Premises to determine whether Tenant has complied and is complying with the terms and conditions of this Lease; (b) to perform maintenance and make repairs and replacements required under the terms hereof to be made by Tenant which may be necessary by reason of Tenant’s failure to do such repair or maintenance after notice from Landlord; or (c) to perform maintenance and make any repairs and replacements in any case where Landlord, in its reasonable judgment, determines that it is necessary or desirable to do so in order to preserve the structural safety of the Building or to correct any condition likely to cause injuries or damages to persons or property. In addition, Landlord may, upon at least forty-eight hours prior written notice to Tenant, enter upon the Premises to show the Premises to others for the purpose of renting the same upon the termination of the Lease Term or selling or financing the Building.

10.6    Tenant Equipment.

10.6.1    In the event, during the Lease Term, Tenant purchases additional equipment which is not replacing existing Equipment, such additional equipment shall be Tenant’s personal property and title to such equipment shall remain with Tenant.

10.6.2    In the event, during the Lease Term, any portion of the Equipment becomes inoperable, such inoperability is not the result of Tenant’s acts or omissions (other than ordinary wear and tear) and such Equipment cannot be repaired at a commercially reasonable cost (Equipment meeting the foregoing requirements being “Replacement Eligible Equipment”), Tenant shall have the right to purchase replacement equipment for the Replacement Eligible Equipment provided that Tenant provides Landlord with written notice of the need for such replacement promptly upon Tenant becoming aware of the same, and such replacement Equipment shall be Tenant’s personal property and title to the such replacement Equipment shall remain with Tenant. Notwithstanding the foregoing, in the event that the proceeds of Landlord’s property insurance policy are used to purchase such replacement equipment, then the replacement equipment shall remain Landlord’s personal property to the extent of the such proceeds are used in proportion to the aggregate cost of such replacement equipment. Tenant shall be responsible for removing and disposing any existing Equipment which is replaced at Landlord’s sole cost and expense and Landlord shall be entitled to any proceeds from the resale, salvage or other disposition of such Equipment.

10.6.3    In the event, during the Lease Term, Tenant replaces any Equipment which is not Replacement Eligible Equipment, such replacement shall be subject to the provisions of Section 10.3 above and such replacement equipment shall be the property of Landlord.

ARTICLE 11 - INSURANCE

11.1    Tenant’s Required Insurance. At all times during the Term of this Lease, Tenant shall maintain, at its sole cost and expense, the following insurance policies and comply with the following obligations (such policies and compliance, collectively, the “Tenant Required Insurance”):

11.1.1    Tenant shall maintain policies of cause of loss-special risk form (formerly “all-risk”) property insurance covering trade fixtures, equipment, merchandise inventory and all other personal property including the Tenant Improvements from time to time in, on or upon the Premises, in an amount not less than one hundred percent (100%) of their actual replacement cost from time to time existing during the Term, providing protection against any peril included within the former classification of “all risk” inclusive of sprinkler leakage, wind and terrorism with sublimits for flood and earthquake, if applicable. Tenant shall also be required to obtain extra expenses and business

-23-

interruption insurance (on an “actual loss sustained” basis) for periods and with limits not less than twelve (12) months of the Base Rent payable by Tenant.

11.1.2    During any Tenant Improvements or Alterations, Tenant, or Tenant’s contractor, shall maintain builder’s risk insurance for not less than the full completed project insurable value, covering the same risks and otherwise complying with the same requirements as set forth in Section 11.1.1 above. Tenant’s builder’s risk insurance shall also cover: (a) loss of materials, equipment, machinery, and supplies whether on-site, in transit, or stored off-site, or of any temporary structures, hoists, sidewalks, retaining walls, and underground property; (b) soft costs, plans, specifications, blueprints and models; (c) demolition and increased cost of construction, including increased costs arising from changes in Laws and coverage for operation of building Laws, all subject to a sublimit reasonably satisfactory to Landlord; and (d) business interruption on an actual loss sustained in an amount equal to at least 12 months of the Base Rent payable by Tenant. Notwithstanding anything to the contrary herein, Tenant shall have no obligation to maintain builder’s risk insurance as required in this Section 11.1.2 for Minor Alterations as appropriate given the nature of such Minor Alterations.

11.1.3    Tenant shall maintain the following insurance for personal injury, bodily injury, death, accident and property damage: (a) public liability insurance, including commercial general liability insurance, in an amount of not less than $1,000,000 per occurrence with a general aggregate limit of not less than $2,000,000; (b) owned (if any), hired, and non-owned automobile liability insurance in an amount of not less than $1,000,000 per accident; and (c) umbrella liability insurance in an amount not less than $5,000,000 per occurrence. Tenant’s liability insurance shall include coverage for liability arising from premises and operations, elevators, escalators, independent contractors, contractual liability (including indemnities), and products and completed operations. All Tenant liability insurance shall name Landlord and its Mortgage Lender as an “additional insured” by an endorsement reasonably satisfactory to Landlord. Liability insurance required to be carried by Tenant is to be primary and noncontributory as is insurance carried by Landlord.

11.1.4    Tenant shall maintain workers’ compensation and disability insurance as Law requires.

11.1.5    Tenant shall maintain such other types and amounts of insurance for the Premises and its operations as Landlord or its Mortgage Lender shall from time to time reasonably require, consistent with insurance commonly maintained for similarly situated properties in the St. Louis City and St. Louis County area.

11.1.6    Tenant shall secure all Tenant Required Insurance from domestic insurer(s) authorized to do business in the State and reasonably satisfactory to Landlord with: (a) a claims paying ability of not less than “A” (or the equivalent) by S&P and one other Rating Agency satisfactory to Landlord; and (b) “A:X” or better financial strength rating by AM Best. Tenant shall obtain Landlord’s reasonable approval of the form, substance, amounts, risk coverage, sublimits, deductibles and insureds for all Tenant Required Insurance. Tenant Required Insurance shall contain such provisions as Landlord deems reasonably necessary or desirable to protect its interest, including endorsement stating that neither Tenant, Landlord, nor any other party shall be deemed a co-insurer. Tenant shall pay the premiums for all Tenant Required Insurance when due and payable. Tenant shall not finance insurance premiums under any arrangement that could (if any premium loan payment is not made) result in the premature cancellation of any Tenant Required Insurance. Tenant shall deliver to Landlord, promptly upon issuance, copies of certificates of insurance and, if requested by Landlord in writing, the insurance policies, for all Tenant Required Insurance. At least 30 days before any

-24-

policy expires, Tenant shall deliver evidence of renewal in compliance with the Loan Documents. If Tenant fails to do so by such date, then without limiting Landlord’s Remedies, Landlord may (but shall have absolutely no obligation to) obtain any Tenant Required Insurance, in which event Tenant shall reimburse Landlord for the cost thereof, plus five percent (5%) as an administrative fee, upon demand, and such obligation shall constitute Additional Rent due hereunder.

11.1.7    In each insurance policy (or an endorsement thereto), Tenant shall use commercially reasonable efforts to cause the carrier to: (a) agree to endeavor to provide Landlord with at least 10 days’ prior written notice of cancellation, termination, or nonrenewal of such policy; (b) waive any right to claim any premiums and commissions against Landlord, provided that the policy need not waive the requirement that the premium be paid in order for a claim to be paid to the insured; and (c) allow Landlord to pay premiums to continue such policy upon notice of cancellation for nonpayment. If Landlord pays any such premiums, then Tenant shall reimburse Landlord for the cost thereof, plus five percent (5%) as an administrative fee, as Additional Rent. Every property insurance policy shall provide that as to Landlord’s interest, such policy shall remain valid and shall insure Landlord regardless of any: (i) named insured’s act, failure to act, negligence, or violation of warranties, declarations, or conditions; (ii) occupancy or use of the Premises for purposes more hazardous than those permitted; or (iii) Landlord’s exercise of any Landlord’s remedies.

11.1.8    Tenant shall not carry separate insurance, concurrent in kind or form or contributing in the event of Loss, with any Tenant Required Insurance. Tenant may, however, carry insurance for the Premises, in addition to Tenant Required Insurance, but only if such additional insurance: (a) does not violate or entitle the carrier to assert any defense or disclaim any primary coverage under any Tenant Required Insurance; (b) mutually benefits Tenant and Landlord, as their interests may appear; and (c) otherwise complies with this Lease.

11.1.9    Notwithstanding anything to the contrary in this Lease, if at any time Landlord has not received satisfactory written evidence that Tenant maintains all Tenant Required Insurance in full force and effect in full compliance with this Lease and has paid all required premiums, then Landlord may at its option take such action as Landlord deems necessary to protect Landlord’s interests, including obtaining such insurance coverage(s) as Landlord shall deem appropriate. Landlord’s expenses in doing so, and any other expenses or losses that Landlord suffers or incurs as a result of Tenant’s failure to perform any obligation regarding Tenant Required Insurance, shall be reimbursed by Tenant, together with payment of an administrative fee to Landlord of five percent (5%) of Landlord’s cost of performance, shall be paid upon demand and shall constitute Additional Rent due hereunder. If at any time Landlord makes any determination or request regarding the amount, scope, or terms of any Tenant Required Insurance, any such determination or request shall impose no obligation or liability on Landlord. Tenant shall not rely upon any such determination or request. Tenant acknowledges that any such determination or request would be made solely for Landlord’s own benefit and not for Tenant’s benefit. Tenant shall retains sole responsibility for the adequacy and appropriateness of its insurance program without relying on Landlord.

11.2    Landlord’s Required Insurance. At all times during the Term of this Lease, Landlord shall maintain the following insurance policies and comply with the following obligations (such policies and compliance, collectively, the “Landlord Required Insurance”):

11.2.1    Landlord shall maintain in effect policies of cause of loss-special risk form (formerly “all-risk”) property insurance covering the Building and the Equipment from time to time in, on or upon the Premises (but expressly excluding those items required to be insured by Tenant

-25-

pursuant to Section 11.1.1 above), in an amount not less than one hundred percent (100%) of their actual replacement cost (excluding the Building footers and foundation at Landlord’s option) from time to time existing during the Term.

11.2.2    Landlord shall maintain the following insurance for personal injury, bodily injury, death, accident and property damage: public liability insurance, including commercial general liability insurance, in an amount not less than $1,000,000 per occurrence with a general aggregate limit not less than $2,000,000.

11.2.3    Landlord shall also maintain the following insurance, at Landlord’s sole cost, for personal injury, bodily injury, death, accident and property damage: (a) owned (if any), hired, and non-owned automobile liability insurance in an amount not less than $1,000,000 per accident; (b) umbrella liability insurance in an amount not less than $5,000,000 per occurrence; and (c) worker’s compensation insurance as required by law. Upon written request of Tenant, Landlord shall provide Tenant with evidence of coverage of the insurance required to be carried by Landlord hereunder.

11.2.3    Landlord shall secure all Landlord Required Insurance from domestic insurer(s) authorized to do business in the State with: (a) a claims paying ability of not less than “A” (or the equivalent) by S&P and one other Rating Agency satisfactory to Landlord; and (b) “A:X” or better financial strength rating by AM Best.

11.2.4    To the extent that the premiums for the Landlord Required Insurance exceed the total aggregate amount of $75,000 (the “Insurance Premium Cap”) for any calendar year, Tenant shall pay to Landlord the amount by which such premiums exceed the Insurance Premium Cap as Additional Rent hereunder within thirty (30) days after Landlord’s written request for such payment. Tenant shall further reimburse Landlord for the cost of any deductibles paid by Landlord with respect to the Landlord Required Insurance from time to time within thirty (30) days after Landlord’s written demand therefor; provided that the event giving rise to an insurance claim was not caused by Landlord’s wrongful acts or omissions hereunder. Notwithstanding the foregoing, in no event shall Tenant be responsible for payment of fines, costs, late charges, liquidated damages, penalties, or related interest charges related to the Landlord Required Insurance unless resulting from Tenant’s failure to timely pay any amount it is required to pay under this Section 11.2.4.

11.3    Waiver of Subrogation. To the extent permitted by law, and without affecting the coverage provided by insurance required to be maintained hereunder, Landlord and Tenant each waive any right to recover against the other for damages to all or any portion of the Premises, the Building, the Equipment, the Tenant Improvements or any of Tenant’s personal property which is covered or which would be covered by the property insurance required to be maintained by the Parties as provided herein (inclusive of any and all deductibles). This provision is intended to waive, fully and for the benefit of each Party, any rights and/or claims which might give rise to a right of subrogation by any insurance carrier insuring either Party with property insurance. The coverage obtained by each Party pursuant to this Lease shall include, without limitation, a waiver of subrogation by the carrier which conforms to the provisions of this Section.

12.2    Remedies. If an Event of Default occurs, then Landlord may exercise any one or more of the following remedies, to the extent permitted by law, or any other legal or equitable remedy permitted under applicable Laws:

12.2.1    Landlord may terminate this Lease (and accelerate the Expiration Date) upon the delivery of notice thereof to Tenant and Landlord shall have the right to immediate possession of the Premises and Tenant shall peacefully surrender possession of the Premises to Landlord. Tenant hereby waives any and all rights it may have, at law or in equity, to the receipt of notice of default or demand for forfeiture, except as expressly provided herein. In the event Tenant holds the Premises over beyond the termination of the Lease Term, Landlord shall have the right to recover Landlord's cost in recovering possession of the Premises (including, without limitation, reasonable attorneys' fees and litigation costs and expenses), such amounts as may be permitted under applicable Law and any other amounts due and payable to Landlord hereunder (including, without limitation, past-due Rent). In addition to the foregoing, if the Lease is terminated as aforesaid, then Landlord shall also have the right to recover from Tenant all damages allowable to Landlord under applicable Law as a result of an Event of Default under this Lease.

In the event of such reletting, Landlord shall receive the rents therefor, applying the same first, to the repayment of reasonable expenses as Landlord may have incurred in connection with said resumption of possession, preparing for reletting and reletting (including, without limitation, remodeling costs, brokerage and attorneys' fees), and, second, to the payment of damages and amounts equal to the Base Rent and Additional Rent due hereunder and to the cost of performing the other obligations of Tenant as herein provided.

12.2.4    Tenant shall pay to Landlord, upon demand, interest at the Default Rate, compounded monthly, on any past-due payments of Base Rent, Additional Rent or other amounts due hereunder, which interest shall commence to accrue on the first day after the due date of any such payment regardless of any cure or grace periods which may be granted hereunder or with respect thereto.

If Landlord breaches its obligation to perform a Repair hereunder, Tenant shall have those rights under Section 9.3 hereof with respect thereto.

12.4    Limitation of Landlord’s Liability.

12.4.1    The term “Landlord” as used herein shall mean only the current owner or owners (and their agents) of the Premises. In the event of any actual or alleged failure, breach or default hereunder by Landlord, Tenant’s sole and exclusive remedy will be against Landlord’s interest in the Property and the rents, issues, profits and proceeds thereof.

Such option must be exercised, if at all, by giving written notice to the non-terminating Party within sixty (60) days after receipt of notice of such taking and such termination shall be effective on the effective date of such taking. In the event this Lease is not terminated as a result of any such taking, any obligations of Tenant hereunder and all of the other provisions of this Lease shall remain in full force and effect; provided, however, that this Lease shall remain and continue in full force and effect relative to the portion of the Premises not so taken until the expiration of the Lease Term and Tenant shall be entitled to an equitable abatement of Base Rent based upon the utility and extent of the portion of the Premises so taken. Notwithstanding the foregoing, the taking of any landscaped areas shall not result in the reduction of any of the Rent.

13.4    Damages. All damages awarded for any such taking under the power of eminent domain, whether for the whole or a part of the Premises, shall belong to and be the property of Landlord and are hereby assigned by Tenant to Landlord; provided, however, that so long as Tenant is not in default hereunder, Tenant may make a separate claim the cost of relocation provided the same does not reduce Landlord’s award.

13.6    Voluntary Sale.

ARTICLE 14 - DAMAGE OR DESTRUCTION

14.1    Casualty. A fire or other casualty of the type covered by the insurance required to be maintained herein shall be referred to herein as “Casualty.” Tenant shall promptly give notice to Landlord of any damage to, or destruction of, the Premises caused for any reason including, without limitation, a Casualty. If the Premises are damaged or destroyed as aforesaid after Substantial Completion by a Casualty, then, unless the Lease is terminated as provided in this Article 14, Landlord shall repair and restore the Premises (but not the Alterations, Tenant Improvements, trade fixtures, equipment, merchandise, inventory or personal property of Tenant) to substantially the same condition of the Premises immediately prior to such Casualty. Such repair and restoration being collectively referred to herein as the "Restoration."

14.2    Minor Loss. If the Premises are damaged or destroyed after Substantial Completion by a Casualty resulting in a loss equal to or less than an aggregate loss of $250,000 (exclusive of

-30-

damage to Tenant's personal property), then, subject to the provisions of any Mortgage then in effect, the net insurance proceeds available from Landlord’s property insurance after any expenses incurred in obtaining payment of such proceeds (the “Proceeds”) shall be used by Landlord and applied to payment for the costs of the Restoration.

14.3    Substantial Loss. If the Premises are damaged or destroyed after Substantial Completion by a Casualty resulting in a loss which is greater than an aggregate loss of $250,000, then Landlord (or Tenant in the case of clauses (c), (d) and (e)) shall have the right to terminate this Lease provided (a) the Casualty is not covered by Landlord’s insurance policies, (b) if the Proceeds are insufficient to pay for all costs of the Restoration (including if due to actions of any Mortgage Lender), (c) the Restoration cannot be completed because the same would not comply with applicable Laws, (d) the Restoration cannot be completed with one (1) year after the date of the Casualty, as reasonably determined by Landlord, or (e) such Casualty occurs during the final two (2) Lease Years of the then current Term. Landlord or Tenant, as applicable, shall exercise its right to terminate this Lease pursuant to this Section 14.3,if at all, by providing written notice thereof to the other Party within sixty (60) days after the occurrence of such Casualty. If Landlord terminates this Lease, then Landlord shall be entitled to all Proceeds payable under Landlord’s Required Insurance with respect to such Casualty. If Landlord does not terminate this Lease, then Landlord shall be obligated to perform the Restoration. Tenant shall have the option to terminate this Lease if Landlord does not complete Restoration within such one (1) year of the date of the casualty giving rise to such Restoration obligations by providing written notice to Landlord. Tenant shall have the right, but not the obligation, to pay to Landlord an amount by which the cost to complete a Restoration exceeds the amount of the insurance proceeds available with respect thereto (the “Insurance Shortfall”), in which event Landlord shall not have the right to terminate this Lease due to the insufficiency of insurance proceeds. In the event Tenant pays the Insurance Shortfall to Landlord, the same shall be credited against the Purchase Option Price (as defined on Exhibit I) payable by Tenant to Landlord should Tenant acquire the Property pursuant to the Purchase Option (as defined on Exhibit I).

14.4    Rent Abatement. If the Premises may not be reasonably used by Tenant for Tenant’s Permitted Use due to a Casualty, then Tenant’s obligation to pay Base Rent hereunder shall be equitably abated until such time as Tenant may again use the Premises for Tenant’s Permitted Use.

14.5    Casualty Prior to Substantial Completion. If the Premises are damaged or destroyed by a Casualty prior to Substantial Completion, then (a) the Proceeds shall be paid to Landlord or as otherwise provided in any Mortgage then in effect, and (b) Landlord shall complete Restoration and may use the Proceeds to pay for the cost thereof. Landlord shall be responsible for any deductible applicable to such Casualty. In no event shall Landlord have any obligation to repair or restore any of the Tenant Improvements or any of Tenant’s other property.

ARTICLE 15 - ASSIGNMENT AND SUBLETTING

15.1    Assignment and Subleases Generally.

15.1.1.    Subleases. Tenant shall not sublease all or any portion of the Premises to any Person without obtaining the prior written consent of Landlord in each instance, which consent may be granted or withheld by Landlord in its sole and absolute discretion except as set forth herein. Any sublease of the Premises or any portion thereof without the prior written consent of Landlord shall constitute an Event of Default hereunder and shall be void and of no force or effect. A consent by Landlord to one such subletting shall not be deemed a consent to any subsequent subletting. Tenant shall reimburse Landlord an amount not to exceed $2,500 for any expenses incurred by Landlord in

-31-

reviewing, and approving or denying, any request by Tenant for permission to sublease the Premises or any portion thereof. Notwithstanding any sublease of the Premises, or any portion thereof or any consent of Landlord thereto, Tenant shall remain fully and primarily liable under this Lease. Tenant shall be responsible for and shall pay all brokerage commissions and expenses incurred in connection with any subletting of the Premises. If an Event of Default occurs and this Lease, or Tenant’s right to possession of the Premises under this Lease is terminated, then, at the sole option of Landlord, any such sublease then in effect shall be deemed to be terminated upon Landlord’s delivery of written notice thereof to such sublessee. Notwithstanding anything to the contrary in the foregoing, Tenant shall have the right to sublease the Premises or any portion thereof to an Affiliate of Tenant without the necessity of obtaining Landlord’s prior written consent thereto, provided that all of the following conditions are satisfied: (a) no Event of Default has occurred and is continuing on the date of the sublease, (b) Tenant notifies Landlord of such sublease in writing prior to the execution of such Sublease, (c) Tenant is not relieved of primary liability for the performance of all obligations, covenants and responsibilities under this Lease to be performed by Tenant, and (d) there will be no change in Tenant’s Permitted Use of the Premises as a result of such subletting. If Tenant subleases any space in the Premises to a third party who is not an Affiliate of Tenant, and Tenant receives any consideration therefor which exceeds the Base Rent (or in the case of a sublease of a portion of the Premises, the rate of such Base Rent) payable by Tenant under this Lease, then the Parties agree that Tenant shall pay the 50% of the amount such excess consideration to Landlord promptly upon receipt.

15.1.2.    Assignment. Tenant shall not assign, convey, hypothecate, encumber, lien or otherwise transfer all or any portion of its interest under this Lease (each a “Transfer”) to any third party or grant a mortgage against Tenant’s interest herein without obtaining the prior written consent of Landlord in each instance, which consent may be granted or withheld by Landlord in its sole and absolute discretion except as set forth herein. Any such Transfer without the prior written consent of Landlord shall constitute an Event of Default hereunder and shall be void and of no force or effect. A consent by Landlord to one Transfer shall not be deemed a consent to any subsequent Transfer. Tenant shall reimburse Landlord an amount not to exceed $2,500 for any expenses incurred by Landlord in reviewing, and approving or denying, any request by Tenant for permission to Transfer Tenant’s leasehold interest under this Lease. Tenant shall be responsible for and shall pay all brokerage commissions and expenses incurred in connection with any Transfer of Tenant’s leasehold interest under this Lease. Notwithstanding any Transfer, Tenant shall remain fully and primarily liable for the performance of Tenant’s obligations under this Lease. Notwithstanding anything to the contrary in the foregoing, Tenant shall have the right to assign this Lease to an Affiliate of Tenant without the necessity of obtaining Landlord’s prior written consent thereto, provided that all of the following conditions are satisfied: (a) no Event of Default has occurred and is continuing on the date of the assignment, (b) Tenant notifies Landlord of such assignment in writing not less than thirty (30) days prior to such assignment, (c) the assignor is not relieved of primary liability for the performance of all obligations, covenants and responsibilities under this Lease to be performed by Tenant, and (d) there will be no change in Tenant’s Permitted Use of the Premises as a result of such assignment. If Tenant Transfers this Lease to a third party who is not an Affiliate of Tenant, and Tenant receives any consideration therefor, then the Parties agree that Tenant shall pay 50% of the amount such consideration to Landlord promptly upon receipt.

15.1.3.    Subleases and Assignments Procedure. If Tenant proposes to Transfer this Lease or sublet all or any portion of the Premises and requests the consent of Landlord thereto, then Tenant shall give Landlord a written request therefor which shall include the following information:

(a)    The name, contact person, address, telephone and facsimile number of the proposed sublessee, assignee, mortgagee or transferee;

-32-

(b)    in the case of a sublease, a description of the portion of the Premises to be subleased and any Alterations to be made in connection therewith;

(c)    a description of any Alterations to be made by the assignee;

(d)    a description of the proposed activities by the proposed sublessee, assignee or transferee to be performed at the Premises and evidence that the same will comply with this Lease, all applicable zoning regulations and the Permitted Exceptions;

(e)    financial or other credit information regarding the proposed sublessee, assignee or transferee in reasonably sufficient detail and scope to evidence the satisfaction of any conditions imposed by Landlord in consenting to such sublease or Transfer;

(f)    a description of the material business terms of the sublease or Transfer agreement;

(g)    such other information as Landlord may reasonably request with respect to any particular sublease or Transfer; and

(h)    If Landlord consents to the same, then the proposed sublessee, assignee, mortgagee or Transferee shall execute such documents as may be reasonably required by Landlord to evidence its obligations to be bound by and be subject to, the terms of this Lease or to satisfy any other conditions imposed by Landlord in granting such consent.

15.2    Right to Collect Rent. If the Premises or any part thereof is subleased or occupied by any person or entity other than Tenant, then, after an Event of Default by Tenant hereunder, Landlord shall have the right, but not the obligation, to collect Rent from the subtenant or occupant and apply the net amount collected to the Base Rent and Additional Rent herein reserved, but no such subletting, occupancy or collection shall be deemed a waiver of the agreements of the Parties under this Article 15, or the acceptance of subtenant or occupant as tenant, or a release of Tenant from the further performance of the terms, covenants, and conditions on the part of Tenant to be observed or performed hereunder, and, subsequent to any subletting, Tenant's liability hereunder shall continue notwithstanding any subsequent modification or amendment hereof or the release of any subsequent tenant hereunder from any liability, to all of which Tenant hereby consents in advance.

15.3    Change in Control. For purposes of this Lease, the term “Change in Control” means, with respect to Tenant, any issuance, redemption, sale, assignment or other transfer of shares of the voting stock, partnership interests, membership interests (or equivalent ownership interest if Tenant is a business organization other than a corporation, partnership or limited liability company) of Tenant such that, upon the effectiveness of such issuance, redemption, sale, assignment or transfer, (a) the identity of the person or persons beneficially owning more than fifty percent (50%) of such voting stock, partnership interests, membership interests (of equivalent ownership interests) changes from that prior to such issuance, redemption, sale, assignment or transfer, or (b) the identity of the person or persons possessing the right to control the management of Tenant changes from that prior to such issuance, redemption, sale, assignment or transfer. Notwithstanding anything to the contrary in the foregoing, if a majority of the shares of voting stock of Tenant are or become listed, and publicly traded, on a reasonably legitimate and internationally recognized stock exchange, then so long as such shares are so listed and publicly traded, no Change in Control shall be deemed to have occurred as a

-33-

result of the issuance of such shares to the public or any subsequent sale, assignment or transfer of such shares on such exchange; provided, however, that if a majority of the voting shares of Tenant become beneficially owned by a relatively small number of investors as part of a so-called “going private” transaction or in a transaction reasonably likely to result in a de-listing of such shares from any such exchange, then a Change in Control will be deemed to have occurred as a result of any such transaction. A Change in Control shall constitute a Transfer under this Lease requiring Landlord’s consent.

15.4    Merger or Consolidation. The merger of Tenant into another entity or the consolidation of Tenant with one or more other entities shall each constitute a Transfer under this Lease requiring Landlord’s consent.

ARTICLE 16 - QUIET ENJOYMENT

16.1    Quiet enjoyment. If Tenant pays the Rent and observes and performs all of the obligations, covenants, conditions and provisions on Tenant's part to be performed and observed under this Lease, then Tenant shall have and Landlord covenants Tenant’s quiet use and possession of the Premises throughout the Lease Term and any extensions thereof, free of claims by or through Landlord.

16.2    Signs. So long as no Event of Default is continuing, Tenant shall have the right to install back-lit building signage on the exterior of the Building. Such exterior Building signage shall be subject to all applicable governmental approvals (including the City of Creve Coeur, Missouri) as well as Landlord’s approval, in its sole and absolute discretion. Tenant further shall have the right from time to time to install interior Building signage which is not visible from the exterior of the Building. Any and all signs installed by Tenant on the Premises shall be installed at Tenant's sole cost and expense and shall be removed by Tenant at the Expiration Date or earlier termination of Tenant's possession of the Premises at Tenant's sole cost and expense. Tenant shall be obligated to repair any damage caused by any such removal and to reimburse Landlord for the cost of painting any areas of the Building affected by any stains or discoloration caused by the removal of any such sign or signs. All such signs shall comply with all Laws and all title restrictions affecting the Premises.

16.3    Liens. Landlord's title to the Premises is and always shall be paramount to the title of Tenant and nothing in this Lease shall empower Tenant to do any act which may cause a lien on or encumber the title of Landlord. Tenant has no authority or power to cause or to permit any lien or encumbrance of any kind whatsoever, whether created by the act of Tenant, operation of law or otherwise, to attach or to be placed upon the Premises or the Building and any and all such liens and encumbrances created by Tenant shall attach only to Tenant's interest in the Premises.

ARTICLE 17 – LANDLORD’S RIGHT TO MORTGAGE, SELL OR ASSIGN RENTS

17.1    Landlord’s Right to Mortgage. Landlord shall have the right at any time and from time to time to place one or more Mortgages on all or any part of the Premises and to assign the Rents as further collateral for any such Mortgage Loan. Should Landlord assign the Rents to any Mortgage Lender and such Mortgage Lender demand in writing that Tenant pay the Rents directly to such Mortgage Lender, Landlord releases Tenant from any claim or demand based upon Tenant’s compliance with such Mortgage Lender’s demand to directly receive the Rents.

17.2    Landlord’s Right to Sell or Convey. Nothing contained in this Lease shall be deemed in any way to limit or restrict or otherwise affect Landlord’s absolute right at any time to convey its

-34-

interest in the Premises following Substantial Completion. In the event of any such conveyance, (a) the transferor shall be relieved from and after the date of such conveyance of all liability relative to obligations of the Landlord to be performed under this Lease after the effectiveness of such conveyance (but nothing herein shall relieve the transferor of any liabilities hereunder arising out of acts or events occurring prior to such conveyance, unless expressly assumed by the transferee), (b) Tenant shall pay and attorn to the transferee, the Rent payable by Tenant to Landlord, and such transferee shall fully recognize Tenant’s tenancy and all of its rights under this Lease, and (c) the grantor under such conveyance shall assign or deliver to the transferee the Security Deposit to the extent the same has not been applied as provided herein.

17.3    Subordination. This Lease, and all rights of Tenant hereunder, are and shall be subject and subordinate to all Mortgages which may now affect all or any portion of the Premises and to all renewals, modifications, replacements and extensions thereof; provided, however, that if the holder of any such Mortgage elects (in its sole discretion and in writing) to subordinate such holder's Mortgage to this Lease (which election may be made at any time), then such election shall be binding on Tenant, and, if the Premises is thereafter sold through foreclosure, then the Tenant shall attorn to the purchaser at such sale as its landlord. Tenant shall, if requested by any Mortgage Lender or prospective Mortgage Lender, execute and deliver such commercially reasonable subordination, nondisturbance and attornment agreement as such Mortgage Lender may request which agreement shall provide, among other commercially reasonable terms as may be required by such Mortgage Lender, that this Lease will be subordinate to the lien of such Mortgage Lender’s Mortgage, that Tenant’s right to possession of the Premises will not be disturbed so long as no Event of Default has occurred and that Tenant will attorn to the purchaser of the Premises at any foreclosure sale conducted under such Mortgage.

17.4    Estoppel. Within thirty (30) days after a written request from Landlord, Tenant shall execute and deliver to Landlord or such person as may be designated by Landlord a properly completed Estoppel Certificate in the form attached hereto as Exhibit E.

ARTICLE 18 - SECURITY DEPOSIT

Tenant shall deposit with Landlord on the Effective Date the Security Deposit as security for Tenant’s full and faithful performance of every provision of this Lease. Landlord shall be required to deposit the Security Deposit into a separate interest-bearing deposit account that is not commingled with other funds. Landlord shall have no liability in connection with the rate of interest which may or may not be paid with respect to such deposit account and shall have no obligation to achieve any particular return thereon. If an Event of Default occurs, then Landlord may use, apply or retain all or any part of the Security Deposit, together with any interest earned thereon, for the payment of any amount in default or for the payment of any other amount which Landlord may expend or become obligated to expend by reason of Tenant's default or to compensate Landlord for any loss or damage which Landlord may suffer by reason of Tenant's default. If any portion of the Security Deposit is to be used or applied, Tenant shall, within ten (10) Business Days after written demand therefor, deposit with Landlord an amount sufficient to restore the Security Deposit to its original amount and Tenant's failure to do so shall constitute an Event of Default. If Tenant shall fully perform all of the obligations under this Lease to be performed by Tenant, the Security Deposit and its accrued interest, or any balance thereof, shall be returned to Tenant promptly after the expiration of the Lease Term and upon Tenant's surrender of the Premises at the time and in the condition required in this Lease.

SECOND AMENDMENT TO LEASE AGREEMENT

THIS SECOND AMENDMENT TO LEASE AGREEMENT (this “Amendment”), dated as of December 10, 2020, is made and entered into by and between 1200 Research Owner, LLC, a Missouri limited liability company (“Landlord”), and Benson Hill, Inc., a Delaware corporation (“Tenant”). Landlord and Tenant shall individually be referred to as a “Party” and collectively as the “Parties”. The following recitals form the basis for this Agreement and are made a material part hereof:

A.Landlord and Tenant have entered into that certain Lease Agreement dated as of October 30, 2020 (as ratified and amended, the “Lease”), as ratified and amended by that certain Ratification and Amendment to Lease Agreement dated as of November 4, 2020, by and between Landlord and Tenant, pursuant to which Tenant leases from Landlord the property commonly known as 1200 Research Blvd., Creve Coeur, St. Louis County, Missouri 63132 (the “Property”);

B.Landlord and Tenant have agreed to amend the terms of the Lease as more particularly set forth herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by the Parties, Landlord and Tenant hereby agree as follows:

1.Capitalized Terms.Capitalized Terms used but not defined herein shall have the meaning ascribed to them in the Lease.

2.Sales Tax Exemption.    Section 6.1 of the Work Letter is hereby deleted in its entirety and replaced with the following new Section 6.1:

“6.1 Pursuant to Section 144.030.2(33) of the Missouri Revised Statutes, certain tangible personal property and utilities purchased for use or consumption directly or exclusively in the research and development of agricultural/biotechnology and plant genomics products and prescription pharmaceuticals consumed by humans or animals are exempted from local sales taxes laws. Tenant has requested that Landlord and Contractor acquire certain Equipment and materials for the Work without paying sale tax with respect thereto based on the foregoing sales tax exemption. Due to the schedule for ordering the Equipment and materials for the Work, there is insufficient time to obtain a letter ruling from the applicable Missouri governmental authority confirming whether such Equipment and materials are exempt from sale tax pursuant to such exemption. Tenant shall indemnify, defend and hold harmless all of the Landlord Indemnified Parties from and against any and all claims, causes of action, suits, arbitration proceedings, taxes (including sales tax and interest and penalties thereon), losses, damages, judgments, settlements, penalties, fines and expenses (including, without limitation, reasonable attorneys' fees and expenses, court costs, expert witness fees and expenses and other dispute resolution expenses) suffered or incurred by any one or more of the Landlord Indemnified Parties resulting from the failure to pay sale taxes on any of the Equipment or the materials used in connection with the Work. Any amounts payable in connection with the foregoing shall be paid by Tenant to Landlord within ten (10) Business Days after Landlord's written request therefor. Without limiting the foregoing, if any taxing authority challenges the nonpayment of such sales tax or determines that such

nonpayment was unlawful or impermissible and, as a condition to contesting or appealing such determination Landlord or Contractor is obligated to pay or escrow all or a portion of such disputed sale tax, Tenant, at its sole cost and expense, shall be responsible for paying or escrowing all such amounts when due. Tenant acknowledges that Landlord and Contractor are unwilling to forego payment of sale taxes on certain Equipment and materials used in connection with the Work without the agreements of Tenant in this Section 6.1. Landlord and Tenant further agree that, for purposes of determining the Project Budget pursuant to Section 3.3 of this Work Letter, Landlord shall exclude from the calculation of Project Costs any sales taxes which are not paid based on the exemption described in this Section 6.1 (unless the same has been disputed by any applicable governmental authority).”

3.Miscellaneous.    This Amendment shall be binding upon the Parties hereto and their respective successors and assigns. Except as expressly modified herein, all other terms, provisions and conditions of the Lease shall remain in full force and effect. In the event of a conflict between the terms of the Lease and the terms of this Amendment, the terms of this Amendment shall prevail and be controlling. This Amendment may be executed in electronic format (including, without limitation, delivery by .pdf, .jpeg or .tif file or execution utilizing DocuSign, AdobeSign or a similar signature program) and in multiple counterparts, and each counterpart shall be deemed an original hereof. Accordingly, this Amendment shall become binding, notwithstanding the execution of separate originals hereof, one by each of the Parties hereto.
