Building Sign is at all times in compliance with all applicable laws, and shall also be subject to the approval of Landlord with respect to size, location, design and content, which approval shall not be unreasonably withheld. Tenant may not modify
the size, design or content of the Building Sign without the prior written approval of Landlord which approval shall not be unreasonably withheld. The costs associated with obtaining the necessary governmental approvals and permitting, and for
designing, producing, installing, maintaining and removing the Building Sign shall be borne by Tenant. Tenant shall bear the cost of illuminating the Building Sign and all costs of operating and maintaining said illumination (including bulbs and

Tenants Property into or out of the Building, or (4) the act, omission, misuse or negligence of Tenant, its agents, contractors, employees or invitees.



B. Tenant shall not make or allow to be made any alterations, additions or improvements to the Premises (collectively,
Alterations),without first obtaining the written consent of Landlord, which consent shall not be unreasonably withheld or delayed; provided however, Tenant shall have the right to perform, without Landlords consent, certain
Alterations that do not cost in excess of $25,000.00 in the aggregate (at any one time), and do not affect any mechanical or electrical or life safety systems or plumbing in the Building, provided that advance notice has been given to Landlord in
each instance. Landlord reserves the right to require Tenant to remove at the end of the Lease Term any Alterations installed without the Landlords consent. Prior to commencing any such Alterations and as a condition to obtaining
Landlords consent where necessary, Tenant shall deliver to Landlord plans and specifications acceptable to Landlord; names and addresses of contractors reasonably acceptable to Landlord; copies of contracts; necessary permits and approvals;
evidence of contractors and subcontractors insurance in accordance with Section 13 hereof; and a payment bond or other security, all in form and amount satisfactory to Landlord. Tenant shall be responsible for insuring that all such
persons procure and maintain insurance coverage against such risks, in such amounts and with such companies as Landlord may reasonably require. All Alterations shall be constructed in a good and workmanlike manner using Building standard materials
or other new materials of equal or greater quality. Landlord, to the extent reasonably necessary to avoid any disruption to the tenants and occupants of the Building, shall have the right to designate the time when any Alterations may be performed
and to otherwise designate reasonable rules, regulations and procedures for the performance of work in the Building. Upon completion of the Alterations, Tenant shall deliver to Landlord as-built plans, contractors affidavits and
full and final waivers of lien and receipted bills covering all labor and materials. All



14



---

Alterations shall comply with the insurance requirements and with applicable codes, ordinances, laws and regulations. Tenant shall reimburse Landlord upon
demand for all reasonable sums, if any, expended by Landlord for third party examination of the architectural, mechanical, electrical and plumbing plans for any Alterations. In addition, if Landlord so requests, Landlord shall be entitled to oversee
the construction of any Alterations, and in such event, Tenant shall reimburse Landlord for Landlords actual out of pocket costs incurred in connection therewith, which may include the cost of management personnel working outside of Normal
Business Hours. Landlords approval of Tenants plans and specifications for any Alterations performed for or on behalf of Tenant shall not be deemed to be representation by Landlord that such plans and specifications comply with
applicable insurance requirements, building codes, ordinances, laws or, regulations or that the Alterations constructed in accordance with such plans and specifications will be adequate for Tenants use.



10. Use of Electrical Services by Tenant. All electricity used
by Tenant in the Premises shall, at Landlords option, be paid for by Tenant by (i) a separate charge or charges billed by the utility company providing electrical service and payable by Tenant directly to such utilities company, or (ii) a
separate charge billed directly to Tenant by Landlord and payable by Tenant as additional rent. Such charge shall be based upon the electric current consumed on the Premises during the Lease Term, the rates, terms and conditions for comparable
service to Tenant directly from The Detroit Edison Company under like conditions, all as determined by an independent meter reader. Landlord shall have the right at any time and from time-to-time during the Lease Term to contract for electricity
service from such providers of such services as Landlord shall elect (each being an Electric Service Provider). Tenant shall cooperate with Landlord, and the applicable Electric Service Provider, at all times and, as reasonably
necessary, shall allow Landlord and such Electric Service Provider reasonable access to the Buildings electric lines, feeders, risers, wiring, and any other machinery within the Premises. Tenants use of electrical services furnished by
Landlord shall not exceed in voltage, rated capacity, or overall load that which is standard for the Building. In the event Tenant shall request that it be allowed to consume electrical services in excess of Building standard, Landlord may refuse to
consent to such usage or may consent upon such conditions as Landlord reasonably elects, and all such additional usage shall be paid for by Tenant as Additional Rent. Landlord, at any time during the Lease Term, shall have the right to separately
meter electrical usage for the Premises or to measure electrical usage by survey or any other method that Landlord, in its reasonable judgment, deems appropriate.



11. Assignment and Subletting.



A. Except in connection with a Permitted Transfer (defined in Section 11E below), Tenant shall not assign,
sublease, transfer or encumber any interest in this Lease or allow any third party to use any portion of the Premises (collectively or individually, a Transfer) without the prior written consent of Landlord, which consent shall
not be unreasonably withheld or delayed. Without limitation, it is agreed that Landlords consent shall not be considered unreasonably withheld if: (1) the proposed transferees financial condition is not adequate for the obligations such
transferee is assuming in connection with the proposed Transfer; (2) the transferees business or reputation is not suitable for the Building considering the business and reputation of the other tenants and the Buildings



15



---

prestige, or would result in a violation of another tenants rights under its lease at the Building; (3) the transferee is a governmental agency or
occupant of the Building; (4) Tenant is in default beyond any applicable notice and cure period; or (5) Landlord or its leasing agent has received a proposal from or made a proposal to the proposed transferee to lease space in the Building within
six (6) months prior to Tenants delivery of written notice of the proposed Transfer to Landlord. Consent by Landlord to one or more Transfers shall not operate as a waiver of Landlords rights to approve any subsequent Transfers. In no
event shall any Transfer or Permitted Transfer release or relieve Tenant from any obligation under this Lease or any liability hereunder.



B. If Tenant requests Landlords consent to a Transfer, Tenant shall submit to Landlord (i) financial statements for the proposed
transferee, (ii) a copy of the proposed assignment or sublease, and (iii) such other information as Landlord may reasonably request. After Landlords receipt of the required information and documentation, Landlord shall either: (1) consent or
reasonably refuse consent to the Transfer in writing; (2) in the event of a proposed assignment of this Lease, terminate this Lease (and thereby release Tenant from any further obligations under this Lease) effective the first to occur of ninety
(90) days following written notice of such termination or the date that the proposed Transfer would have come into effect; and (3) in the event of a proposed subletting, terminate this Lease with respect to the portion of the Premises which Tenant
proposes to sublease (and thereby release Tenant from any further obligations under this Lease with respect to such sublet portion) effective the first to occur of ninety (90) days following written notice of such termination or the date the
proposed Transfer would have come into effect. Tenant shall pay Landlord a review fee of $500.00 for Landlords review of any Permitted Transfer or proposed Transfer. In addition, Tenant shall reimburse Landlord for its actual reasonable costs
and expenses (including, without limitation, reasonable attorneys fees) incurred by Landlord in connection with Landlords review of such proposed Transfer or Permitted Transfer.



C. Tenant shall pay to Landlord fifty percent (50%) of all
cash and other consideration which Tenant receives as a result of a Transfer that is in excess of the rent payable to Landlord hereunder for the portion of the Premises and Lease Term covered by the Transfer within ten (10) business days following
receipt thereof by Tenant.



D. Except as
provided below with respect to a Permitted Transfer, if Tenant is a corporation, limited liability company, partnership or similar entity, and the person, persons or entity which owns or controls a majority of the voting interests at the time
changes for any reason (including but not limited to a merger, consolidation or reorganization), such change of ownership or control shall constitute a Transfer. The foregoing shall not apply so long as Tenant is an entity whose outstanding stock is
listed on a nationally recognized security exchange, or if at least eighty percent (80%) of its voting stock is owned by another entity, the voting stock of which is so listed.



E. Tenant may assign its entire interest under this Lease or sublet the Premises (i) to any entity
controlling or controlled by or under common control with Tenant or (ii) to any successor to Tenant by purchase, merger, consolidation or reorganization (hereinafter,



16



---

collectively, referred to as Permitted Transfer)without the consent of Landlord, provided: (1) Tenant is not in default under this Lease;
(2) if such proposed transferee is a successor to Tenant by purchase, said proposed transferee shall acquire all or substantially all of the stock or assets of Tenants business or, if such proposed transferee is a successor to Tenant by
merger, consolidation or reorganization, the continuing or surviving entity shall own all or substantially all of the assets of Tenant; (3) with respect to a Permitted Transfer to a proposed transferee described in clause (ii), such proposed
transferee shall have a net worth which is at least equal to the greater of Tenants net worth at the date of this Lease or Tenants net worth as of the day prior to the proposed purchase, merger, consolidation or reorganization as
evidenced to Landlords reasonable satisfaction; and (4) Tenant shall give Landlord written notice at least thirty (30) days prior to the effective date of the proposed purchase, merger, consolidation or reorganization.



12. Construction Liens. Tenant will not permit any construction
liens or other similar liens to be placed upon the Property. If a lien is attached to the Property, then, in addition to any other right or remedy of Landlord, Landlord may, but shall not be obligated to, discharge the same. Any amount paid by
Landlord for any of the aforesaid purposes including, but not limited to, reasonable attorneys fees, shall be paid by Tenant to Landlord within thirty (30) days after demand as Additional Rent. Tenant shall within thirty (30) days after
receiving such notice of lien or claim have such lien or claim released of record, or bonded over to the reasonable satisfaction of Landlord. Tenants failure to comply with the provisions of the foregoing sentence shall be deemed an Event of
Default entitling Landlord to exercise all of its remedies therefor without the requirement of any additional notice or cure period.



13. Insurance.



A. Landlord shall, at all times during the Lease Term, procure and maintain: (i) policies of insurance covering loss or damage to the
Property in an amount equal to the full replacement cost of the Building, including leasehold improvements in the Premises, which shall provide protection against loss by fire and other all-risk casualties including earthquake and flood and such
other property insurance as may be required by Landlords mortgagee or as otherwise desired by Landlord, and (ii) commercial general liability insurance applicable to the Building and the Common Areas, providing a minimum limit of $3,000,000.00
per occurrence.



B. Tenant shall procure and
maintain, at its expense, (i) all-risk (special form) property insurance in an amount equal to the full replacement cost of Tenants Property located in the Premises; (ii) a policy or policies of general liability and umbrella or excess
liability insurance applying to Tenants operations and use of the Premises, providing a minimum limit of $3,000,000.00 per occurrence and in the aggregate, naming Landlord and Landlords Building manager as additional insureds, (iii)
automobile liability insurance covering owned, non-owned and hired vehicles in an amount not less than a combined single limit of $1,000,000.00 per accident, and (iv) workers compensation insurance in accordance with the laws of the State in
which the Property is located and employers liability insurance in an amount not less than $1,000,000.00 each accident, $1,000,000.00 disease-each employee and policy limit, with the insurance policies required under this



17



---

clause (iv) to be endorsed to waive the insurance carriers right of subrogation. Tenant shall maintain the foregoing insurance coverages in effect
commencing on the earlier to occur of the Commencement Date and the date Tenant takes possession of the Premises, and continuing to the end of the Lease Term. Tenant may, at its election, provide the foregoing insurance coverage through blanket
policies covering multiple locations of Tenants operations, provided that the Property shall be identified by schedule or otherwise and provided further that the foregoing limits shall apply to the Premises and Tenants Property as
required herein.



C. The insurance
requirements set forth in this Section 13 are independent of the waiver, indemnification, and other obligations under this Lease and will not be construed or interpreted in any way to restrict, limit or modify the waiver, indemnification and other
obligations or to in any way limit any partys liability under this Lease. In addition to the requirements set forth in Sections 13 and 14, the insurance required of Tenant under this Lease must be issued by an insurance company with a rating
of no less than A-VIII in the current Bests Insurance Guide or that is otherwise acceptable to Landlord, and admitted to engage in the business of insurance in the state in which the Building is located; be primary insurance for all claims
under it and provide that any insurance carried by Landlord, Landlords Building manager, and Landlords lenders is strictly excess, secondary and noncontributing with any insurance carried by Tenant; and provide that insurance may not be
cancelled, nonrenewed or the subject of change in coverage of available limits of coverage, except upon thirty (30) days prior written notice to Landlord and Landlords lenders. Tenant will deliver to Landlord a legally enforceable
certificate of insurance on all policies procured by Tenant in compliance with Tenants obligations under this Lease on or before the date Tenant first occupies any portion of the Premises, at least ten (10) days before the expiration date of
any policy and upon the renewal of any policy. Landlord shall have the right to approve all deductibles and self-insured retentions under Tenants policies, which approval shall not be unreasonably withheld, conditioned or delayed.



D. Neither Landlord nor Tenant shall be liable (by way of
subrogation or otherwise) to the other party (or to any insurance company insuring the other party) for any loss or damage to any of the property of Landlord or Tenant, as the case may be, with respect to their respective property, the Building, the
Property or the Premises or any addition or improvements thereto, or any contents therein, to the extent covered by insurance carried or required to be carried by a party hereto even though such loss might have been occasioned by the negligence or
willful acts or omissions of the Landlord or Tenant or their respective employees, agents, contractors or invitees. Landlord and Tenant shall give each insurance company which issues policies of insurance, with respect to the items covered by this
waiver, written notice of the terms of this mutual waiver, and shall have such insurance policies properly endorsed, if necessary, to prevent the invalidation of any of the coverage provided by such insurance policies by reason of such mutual
waiver. For the purpose of the foregoing waiver, the amount of any deductible applicable to any loss or damage shall be deemed covered by, and recoverable by the insured under the insurance policy to which such deductible relates.



18



---

14. Indemnity. To the extent not expressly prohibited by law, Landlord and Tenant each (in
either case, the Indemnitor) agree to hold harmless and indemnify the other and the others agents, partners, shareholders, members, officers, directors, beneficiaries and employees (collectively, the
Indemnitees) from any losses, damages, judgments, claims, expenses, costs and liabilities imposed upon or incurred by or asserted against the Indemnitees, including without limitation reasonable attorneys fees and expenses,
for death or injury to, or damage to property of, third parties, other than the Indemnitees, that may arise from the negligence or willful misconduct of Indemnitor or any of Indemnitors agents, members, partners or employees. Such third
parties shall not be deemed third party beneficiaries of this Lease. If any action, suit or proceeding is brought against any of the Indemnitees by reason of the negligence or willful misconduct of Indemnitor or any of Indemnitors agents,
contractors, members, partners or employees, then Indemnitor will, at Indemnitors expense and at the option of said Indemnitees, by counsel reasonably approved by said Indemnitees, resist and defend such action, suit or proceeding. In
addition, to the extent not expressly prohibited by law, Tenant agrees to hold harmless and indemnify Landlord and Landlords Indemnitees from any losses, damages, judgments, claims, expenses, costs and liabilities imposed upon or incurred by
or asserted against Landlord or Landlords Indemnitees, including reasonable attorneys fees and expenses, for death or injury to, or damage to property of, third parties (other than Landlords Indemnitees) that may arise from any act
or occurrence in the Premises, except to the extent caused by the negligence or willful misconduct of Landlord, Landlords contractors, or Landlords Indemnitees.



15. Damages from Certain Causes. To the extent not expressly prohibited by law, Landlord shall not be liable
to Tenant or Tenants employees, contractors, agents, invitees or customers, for any injury to person or damage to property sustained by Tenant or any such party or any other person claiming through Tenant resulting from any accident or
occurrence in the Premises or any other portion of the Building caused by the Premises or any other portion of the Building becoming out of repair or by defect in or failure of equipment, pipes, or wiring, or by broken glass, or by the backing up of
drains, or by gas, water, steam, electricity, or oil leaking, escaping or flowing into the Premises (except where due to Landlords grossly negligent or willful failure to make repairs required to be made pursuant to other provisions of this
Lease, after the expiration of a reasonable time after written notice to Landlord of the need for such repairs), nor shall Landlord be liable to Tenant for any loss or damage that may be occasioned by or through the acts or omissions of other
tenants of the Building or of any other persons whomsoever, including, but not limited to riot, strike, insurrection, war, court order, requisition, order of any governmental body or authority, acts of God, fire or theft.



16. Casualty Damage. If the Premises or any part thereof shall
be damaged by fire or other casualty, Tenant shall give prompt written notice thereof to Landlord. In case the Building shall be so damaged that substantial alteration or reconstruction of the Building shall, in Landlords reasonable exercise
of its business opinion as supported by documentation by a certified architect and delivered to Tenant, take more than 180 days to complete (whether or not the Premises shall have been damaged by such casualty), or in the event there is less than
two (2) years of the Lease Term remaining, or in the event Landlords mortgagee should require that the insurance proceeds payable as a result of a casualty be applied to the payment of the mortgage debt, or in the event of any material
uninsured loss to the Building, either Landlord or Tenant may, at its respective option, terminate this Lease by notifying the other in writing of such termination within ninety (90) days



19



---

after the date of such casualty. If Landlord determines that any such damage shall take less than 180 days to complete, upon Tenant reasonable request,
Landlord shall furnish Tenant with supporting documentation from a certified architect. If neither Landlord nor Tenant so elects to terminate this Lease, Landlord shall commence (no later than sixty (60) days following the casualty) and proceed with
diligence to restore the Building, and the improvements located within the Premises to substantially the same condition in which it was immediately prior to the happening of the casualty. Notwithstanding the foregoing, Landlords obligation to
restore the Building, and the improvements located within the Premises shall not require Landlord to expend for such repair and restoration work more than the insurance proceeds actually received by Landlord as a result of the casualty; provided
that Landlord shall have complied with the insurance requirements and limits set forth in Section 13A. When the repairs described in the preceding two sentences have been completed by Landlord, Tenant shall complete the restoration of all
Tenants Property which are necessary to permit Tenants reoccupancy of the Premises. Landlord shall not be liable for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting in any way from such damage or
the repair thereof, except that Rent shall be abated from the date of the damage or destruction for any portion of the Premises that is unusable by Tenant (including without limitation if the Premises is not itself damaged, but the Building has
suffered damage making access to and use of the Premises impracticable), which abatement shall be in the same proportion that the Rentable Area of the Premises which is unusable (or such use is so rendered impracticable) by Tenant bears to the total
Rentable Area of the Premises; provided that Tenant shall not be entitled to any abatement of Rent if the damage or destruction within the Premises is restored within five (5) Business Days after Landlords receipt of written notice from Tenant
of the occurrence of the damage or destruction.



17.
Condemnation. If the whole or any substantial part of the Premises or if the Building or any portion thereof which would leave the remainder of the Building unsuitable for use comparable to its use on the Commencement Date, or if the
land on which the Building or the Parking Deck is located or any material portion thereof, shall be taken or condemned for any public or quasi-public use under governmental law, ordinance or regulation, or by right of eminent domain, or by private
purchase in lieu thereof, then either Landlord or Tenant may, at its respective option, terminate this Lease by written notice to the other party and Rent shall be abated during the unexpired portion of this Lease, effective when the physical taking
of said Premises or said portion of the Building or land shall occur. If this Lease is not terminated, the Rent for any portion of the Premises so taken or condemned shall be abated during the unexpired Lease Term effective when the physical taking
of said portion of the Premises shall occur. All compensation awarded for any taking or condemnation, or sale proceeds in lieu thereof, shall be the property of Landlord, and Tenant shall have no claim thereto, the same being hereby expressly waived
by Tenant, except for any portions of such award or proceeds which are specifically allocated by the condemning or purchasing party for the taking of or damage to trade fixtures of Tenant and moving costs, which Tenant specifically reserves to
itself.



18. Events of Default.



A. The following events shall be deemed to be
Events of Defaultunder this Lease: (i) Tenant fails to pay any Rent when due; provided that the first (1st) such failure during any consecutive twelve (12) month period during the Term shall not be an Event of



20



---

Default if Tenant pays the amount due within ten (10) days after Tenants receipt of written notice from Landlord that such payment was not made when
due; (ii) Tenant fails to perform any other provision of this Lease not described in this Section 18, and such failure is not cured within thirty (30) days (or immediately if the failure involves a hazardous condition) after notice from Landlord,
however, other than with respect to a hazardous condition, if Tenants failure to comply cannot reasonably be cured within thirty (30) days, Tenant shall be allowed additional time (not to exceed ninety (90) additional days) as is reasonably
necessary to cure the failure so long as Tenant begins the cure within thirty (30) days and diligently pursues the cure to completion; (iii) Tenant fails following written notice and within any applicable cure period to observe or perform any of the
covenants with respect to (a) assignment and subletting as set forth in Section 11, (b) construction liens as set forth in Section 12, (c) insurance as set forth in Section 13 or (d) delivering subordination agreements or estoppel certificates
as set forth in Section 24, (iv) the leasehold interest of Tenant is levied upon or attached under process of law; (v) Tenant dissolves; (vi) Tenant abandons or vacates the Premises; (vii) any voluntary or involuntary proceedings are filed by or
against Tenant or any guarantor of this Lease under any bankruptcy, insolvency or similar laws and, in the case of any involuntary proceedings, are not dismissed within sixty (60) days after filing; or (viii) an Event of Default by Tenant under the
Phase I Lease.



B. The following events shall
be deemed to be Landlord Default(s)under this Lease: (i) any representation or warranty made by Landlord under this Lease, including without limitation those enumerated in Section 5.B is untrue; (ii) Landlord fails to perform any
express undertaking of Landlord under this Lease, including without limitation those enumerated in Sections 5.A,5.B
and 5.C; (iii) Landlord defaults in the Phase I Lease; or (iv) Landlord fails to perform any other provision of this Lease not described in this Section 18, and such failure is not cured within thirty (30) days (or immediately if the failure
involves a hazardous condition) after notice from Tenant, however, other than with respect to a hazardous condition, if Landlords failure to comply cannot reasonably be cured within thirty (30) days, Landlord shall be allowed additional time
(not to exceed ninety (90) additional days) as is reasonably necessary to cure the failure so long as Landlord begins the cure within thirty (30) days and diligently pursues the cure to completion.



19. Remedies.



A. Upon the occurrence of any Event of Default, Landlord
shall have the following rights and remedies, subject in all respects to the provisions and limitations of applicable laws, any one or more of which may be exercised without further notice to or demand upon Tenant and which may be pursued
successively or cumulatively as Landlord may elect:



| | (1) | Landlord may re-enter the Premises and attempt to cure any default of Tenant, in which event Tenant shall, upon demand, reimburse Landlord as Additional Rent for all reasonable
costs and expenses which Landlord incurs to cure such default;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



21



---

| | (2) | Landlord may terminate this Lease by giving to Tenant notice of Landlords election to do so, in which event the Lease Term shall end, and all right, title and interest of
Tenant hereunder shall expire, on the date stated in such notice;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) | Landlord may terminate the right of Tenant to possession of the Premises without terminating this Lease by giving notice to Tenant and pursuing its remedies for recovery of
possession in accordance with applicable Michigan law; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (4) | Landlord may enforce the provisions of this Lease by a suit or suits in equity or at law for the specific performance of any covenant or agreement contained herein, or for the
enforcement of any other appropriate legal or equitable remedy, including recovery of all moneys due or to become due from Tenant under any of the provisions of this Lease.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Landlord shall not be required to serve Tenant with any notices or demands as a prerequisite to its exercise of any of its rights or
remedies under this Lease, other than those notices and demands specifically required under this Lease or applicable law. TENANT WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY LAWSUIT BROUGHT BY LANDLORD TO RECOVER POSSESSION OF THE PREMISES FOLLOWING
LANDLORDS TERMINATION OF THIS LEASE OR THE RIGHT OF TENANT TO POSSESSION OF THE PREMISES PURSUANT TO THE TERMS OF THIS LEASE AND ON ANY CLAIM FOR DELINQUENT RENT WHICH LANDLORD MAY JOIN IN ITS LAWSUIT TO RECOVER POSSESSION.



B. If Landlord exercises either of the remedies provided in
Sections 19A(2) or 19A(3), Tenant shall surrender possession and vacate the Premises and immediately deliver possession thereof to Landlord, and Landlord may re-enter and take complete and peaceful possession of the Premises, with process of law,
and Landlord may remove all occupants and property therefrom, using such force as may be necessary to the extent allowed by law, without being deemed guilty in any manner of trespass, eviction or forcible entry and detainer and without relinquishing
Landlords right to Rent or any other right given to Landlord hereunder or by operation of law.



C. If Landlord terminates the right of Tenant to possession of the Premises without terminating this Lease, Landlord shall have the right
to immediate recovery of all amounts then due hereunder. Such termination of possession shall not release Tenant, in whole or in part, from Tenants obligation to pay Rent hereunder for the full Lease Term, and Landlord shall have the right,
from time to time, to recover from Tenant, and Tenant shall remain liable for, all Rent accruing as it becomes due under this Lease during the period from the date of such notice of termination of possession to the stated end of the Lease Term. In
any such case, Landlord shall make reasonable efforts, in accordance with Section 19E hereof, to relet the Premises. In attempting to relet the Premises, Landlord may make repairs, alterations and additions in or to the Premises and redecorate the
same to the extent reasonably deemed by Landlord necessary or desirable, and Tenant upon



22



---

demand shall pay the reasonable cost of all of the foregoing together with Landlords reasonable expenses of reletting. The rents from any such
reletting shall be applied first to the payment of the expenses of reentry, redecoration, repair and alterations and the expenses of reletting (including reasonable attorneys fees and brokers fees and commissions) and second to the
payment of Rent herein provided to be paid by Tenant. Any excess or residue shall operate only as an offsetting credit against the amount of Rent due and owing as the same thereafter becomes due and payable hereunder.



D. If this Lease is terminated by Landlord, Landlord shall
be entitled to recover from Tenant all Rent accrued and unpaid for the period up to and including such termination date, as well as all other additional sums payable by Tenant, or for which, Tenant is liable or for which Tenant has agreed to
indemnify Landlord, which may be then owing and unpaid, and all reasonable costs and expenses, including court costs and reasonable attorneys fees incurred by Landlord in the enforcement of its rights and remedies hereunder. In addition,
Landlord shall be entitled to recover as damages for loss of the bargain and not as a penalty (1) the aggregate sum which at the time of such termination represents the excess, if any, of the present value of the aggregate Rent which would have been
payable after the termination date had this Lease not been terminated, including, without limitation, the amount projected by Landlord to represent Additional Rent for the remainder of the Lease Term, over the then present value of the then
aggregate fair rent value of the Premises for the balance of the Lease Term, including for this purpose the Additional Rent that would constitute a component thereof, such present worth to be computed in each case on the basis of a ten percent (10%)
per annum discount from the respective dates upon which such Rent would have been payable hereunder had this Lease not been terminated, and (2) any damages in addition thereto, including without limitation reasonable attorneys fees and court
costs, which Landlord sustains as a result of the breach of any of the covenants of this Lease other than for the payment of Rent.



E. Landlord shall use commercially reasonable efforts to mitigate any damages resulting from an Event of Default by Tenant under this
Lease. Landlords obligation to mitigate damages after an Event of Default by Tenant under this Lease shall be satisfied in full if Landlord undertakes to lease the Premises to another tenant (a Substitute Tenant) in
accordance with the following criteria: (1) Landlord shall have no obligation to solicit or entertain negotiations with any other prospective tenants for the Premises until Landlord obtains full and complete possession of the Premises including,
without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant; (2) Landlord shall not be obligated to lease or show the Premises, on a priority basis, or offer the Premises to a prospective tenant when
other premises in the Building suitable for that prospective tenants use are (or soon will be) available; (3) Landlord shall not be obligated to lease the Premises to a Substitute Tenant for a rent less than the current fair market rent then
prevailing for similar uses in comparable buildings in the same market area as the Building, nor shall Landlord be obligated to enter into a new lease under other terms and conditions that are unacceptable to Landlord under Landlords then
current leasing policies for comparable space in the Building; (4) Landlord shall not be obligated to enter into a lease with a Substitute Tenant whose use would: (i) violate any restriction, covenant, or requirement contained in the lease of
another tenant of the Building; (ii) adversely affect



23



---

the reputation of the Building; or (iii) be incompatible with the operation of the Building; and (5) Landlord shall not be obligated to enter into a lease
with any proposed Substitute Tenant which does not have, in Landlords reasonable opinion, sufficient financial resources to operate the Premises in a first class manner and to fulfill all of the obligations in connection with the lease thereof
as and when the same become due.



F. The
receipt by Landlord of less than the full Rent due shall not be construed to be other than a payment on account of Rent then due, nor shall any statement on Tenants check or any letter accompanying Tenants check be deemed an accord and
satisfaction, and Landlord may accept such payment without prejudice to Landlords right to recover the balance of the Rent due or to pursue any other remedies provided in this Lease. The acceptance by Landlord of Rent hereunder shall not be
construed to be a waiver of any breach by Tenant of any term, covenant or condition of this Lease. No act or omission by Landlord or its employees or agents during the Lease Term shall be deemed an acceptance of a surrender of the Premises, and no
agreement to accept such a surrender shall be valid unless in writing and signed by Landlord.



G. To the extent allowed by law, all installments of Rent not paid within thirty (30) days after the due date therefor shall bear interest
at the Default Rate from the date due until paid. In the event of any litigation between Tenant and Landlord to enforce or interpret any provision of this Lease or to enforce any right of either party hereto, the unsuccessful party to such
litigation shall pay to the successful party all costs and expenses, including reasonable attorneys fees, incurred therein.



H. In the event of a Landlord Default, Tenant may exercise any and all remedies available to it at law or in equity. Landlord in any event
shall have personal liability in connection with any Landlord Default pertaining to the representations, warranties and covenants by Landlord under Section 5.B of this Lease, notwithstanding anything to the contrary otherwise set forth herein.



20. No Waiver. Failure of either party to
declare any default immediately upon its occurrence, or delay in taking any action in connection with an event of default, shall not constitute a waiver of such default, nor shall it constitute an estoppel against the non-defaulting party, but the
non-defaulting party shall have the right to declare the default at any time and take such action as is lawful or authorized under this Lease. Failure by non-defaulting party to enforce its rights with respect to any one default shall not constitute
a waiver of its rights with respect to any subsequent default.



21. Peaceful Enjoyment. Tenant shall, and may peacefully have, hold, and enjoy the Premises, subject to the other terms hereof, provided that Tenant pays the Rent and other sums herein recited to be paid by Tenant and timely
performs all of Tenants covenants and agreements herein contained.



22. Substitution. Intentionally omitted.

23. Holding Over.If Tenant continues to occupy the Premises after the expiration or
other termination of this Lease or the termination of Tenants right of possession, such occupancy shall be that of a tenancy at sufferance. Tenant shall, throughout the entire holdover period, be subject to all the terms and provisions of this
Lease and shall pay for its use and occupancy an amount (on a per month basis without reduction for any partial months during any such holdover) equal to one hundred fifty percent (150%) of the Base Rent and one hundred percent (100%) of the
Additional Rent due under this Lease for the last full month of the term hereof during the first ninety (90) days of such holdover, and two hundred percent (200%) of such Base Rent and one hundred percent (100%) of such Additional Rent thereafter
during such holdover. No holding over by Tenant or payments of money by Tenant to Landlord after the expiration of the Lease Term shall be construed to extend the Lease Term or prevent Landlord from recovery of immediate possession of the Premises
by summary proceedings or otherwise Tenant shall also be liable to Landlord for all direct and consequential damages which Landlord may suffer by reason of any holding over by Tenant.



24. Subordination to Mortgage; Estoppel Certificate. Tenant
accepts this Lease subject and subordinate to any ground lease, mortgage, deed of trust or other lien presently existing or hereafter arising upon the Premises, or upon the Building or the Property and to any renewals, modifications, refinancings
and extensions thereof, but Tenant agrees that any such mortgagee shall have the right at any time to subordinate such mortgage, deed of trust or other lien to this Lease on such terms and subject to such conditions as such mortgagee may deem
appropriate in its discretion. The provisions of the foregoing sentence shall be self-operative and no further instrument of subordination shall be required. However, Landlord is hereby irrevocably vested with full power and authority to subordinate
this Lease to any mortgage, deed of trust or other lien now existing or hereafter placed upon the Premises,or the
Building or the Property and Tenant agrees within twenty (20) days after written demand to execute such further instruments subordinating this Lease or attorning to the holder of any such liens as Landlord may request; provided, however, that it
shall be a condition of any such subordination by Tenant that the mortgagee, trustee under deed of trust or holder of such other lien agree that, in the event of a default by Landlord and foreclosure of the applicable mortgage, deed of trust or
other lien, the mortgagee, trustee or holder, and any purchaser at foreclosure sale, shall acknowledge Tenants rights under this Lease and shall not disturb Tenants possession of the Premises so long as Tenant is not in default under
this Lease. Tenant agrees that it shall from time-to-time furnish within twenty (20) days after so requested by Landlord, a certificate signed by Tenant certifying as to such matters as may be reasonably requested by Landlord. Any such certificate
may be relied upon by any ground lessor, prospective purchaser, secured party, mortgagee or any beneficiary under any mortgage, deed of trust on the Building or the Property or any part thereof or interest of Landlord therein.



25. Notice. Any notice required or permitted to be given under
this Lease or by law shall be deemed to have been given if it is written and delivered in person or mailed by Registered or Certified mail, postage prepaid, or sent by a nationally recognized overnight delivery service to the party who is to receive
such notice at the address specified in Section 1 of this Lease (and, if no address is listed for Tenant, notices to Tenant shall be delivered to the Premises). When so mailed, the notice shall be deemed to have been given two (2) Business Days
after the date it was mailed. When sent by overnight delivery service, the notice shall be deemed to have been given on the next



25



---

Business Day after deposit with such overnight delivery service. The address specified in Section 1 of this Lease may be changed from time to time by giving
written notice thereof to the other party.



26. Surrender
of Premises. Upon the termination of the Lease Term, or upon any termination of Tenants right to possession of the Premises, Tenant will at once surrender possession of the Premises to Landlord in good condition and repair, ordinary
wear and tear, and damage by fire and the elements, excepted. Tenant shall surrender to Landlord all keys to the Premises and make known to Landlord the combination of all combination locks which Tenant is required to leave on the Premises.



27. Rights Reserved to Landlord. Landlord
reserves the following rights, exercisable without notice, except as provided herein, and without liability to Tenant for damage or injury to property, person or business and without affecting an eviction or disturbance of Tenants use or
possession or giving rise to any claim for setoff or abatement of rent or affecting any of Tenants obligations under this Lease: (1) upon thirty (30) days prior notice to change the name or street address of the Building; (2) to install
and maintain signs on the exterior and interior of the Building (subject in all respects to Tenants signage rights hereunder); (3) to designate and approve window coverings to present a uniform exterior appearance; (4) to retain at all times
and to use in appropriate instances, pass keys to all locks within and to the Premises; (5) to approve the weight, size, or location of heavy equipment, or articles within the Premises; (6) to change the arrangement and location of entrances of
passageways, doors and doorways, corridors, elevators, stairs, toilets and public parts of the Building or Property; (7) to regulate access to telephone, electrical and other utility closets in the Building and to require use of designated
contractors for any work involving access to the same; (8) if Tenant has vacated the Premises during the last six (6) months of the Lease Term, to perform additions, alterations and improvements to the Premises in connection with a reletting or
anticipated reletting thereof without being responsible or liable for the value or preservation of any then existing improvements to the Premises and without effectuating a surrender or entitling Tenant to any abatement of Rent; (9) to enter the
Premises to inspect the same or to show the Premises to prospective purchasers, mortgagees, tenants (during the last twelve months of the Lease Term) or insurers, or to clean or make repairs, alterations or additions thereto, provided that, except
for any entry in an emergency situation or to provide normal cleaning and janitorial service, Landlord shall provide Tenant with reasonable prior notice of any entry into the Premises; and (10) to temporarily close the Premises or the Building to
perform repairs, alterations or additions in the Premises or the Building. In exercising its rights under this Section 27, Landlord shall make commercially reasonable efforts to avoid unreasonably interfering with Tenants business operations
in the Premises.



28. Roof Usage. Landlord shall
provide Tenant the nonexclusive right to install up to two (2) satellite dishes (the Rooftop Equipment) on the roof of the Building in accordance with plans and specifications, and installation methods, approved by Landlord and provided
that the satellite dishes do not damage or impair the integrity of the roof, or invalidate the roof warranty, or impair or cause interference with the operation of any machinery, equipment or apparatus of the Building or other tenants of the
Building. Landlord shall have no responsibility and shall not be obligated to provide any utilities, including, but not limited to, electricity or other power for the operation of the Rooftop Equipment. Tenant shall pay for the cost of all utility
services, including the installation,



26



---

separate metering or submetering, if necessary. Tenant shall reimburse Landlord for any of Landlords consultants or contractors reasonable fees
incurred in connection with the review of any drawings, plans and specifications and the Rooftop Equipment installation. Tenant shall be responsible for the payment of any costs Landlord may incur as a result of the cancellation of any roof warranty
or the denial of any claim under any roof warranty due to the installation or operation of the Rooftop Equipment, unless (i) Landlord had previously approved the installation method, (ii) Landlord had previously approved the contractor performing
such installation, and (iii) the warrantor of the roof (if still in effect) approved the installation. Tenant shall operate and maintain the Rooftop Equipment, at its own cost and expense, in good working order and condition and free from any hazard
to person and property. Tenant shall not place any load upon the roof of the Building, which will exceed the load per square foot, which the roof was designed to carry. Upon termination of Tenants use or right to the use of the Rooftop
Equipment by expiration of time or otherwise, Tenant shall, at its sole cost and expense, remove the Rooftop Equipment and shall restore the roof of the Building to its condition existing prior to the installation of the Rooftop Equipment. Tenant
shall further repair, at its sole cost and expense, any damage or destruction caused by the removal of the Rooftop Equipment. Restoration and repair hereby required to be performed by Tenant shall be performed, at Tenants cost, by a contractor
reasonably approved by Landlord or under the supervision of a representative of Landlord (the cost for whom shall be paid by Landlord and Landlord shall be reimbursed by Tenant) at such time and in such manner that is satisfactory to Landlord.



29. On-Site Amenities. Intentionally omitted.



30. Miscellaneous.



A. If any term or provision of this Lease, or the
application thereof, shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision, shall not be affected thereby, and each term and provision of this Lease shall be valid and enforced
to the fullest extent permitted by law.



B.
Tenant agrees not to record this Lease or any short form or memorandum hereof; provided, however, that this provision shall not be deemed to preclude Tenant from filing information with respect to or a copy of this Lease in connection with any
report required under applicable Federal or State law, including without limitation the requirements of the Securities and Exchange Commission.



C. This Lease and the rights and obligations of the parties hereto shall be interpreted, construed, and enforced in accordance with the
laws of the state in which the Building is located.



D. The term Force Majeureshall mean strikes, riots, acts of God, shortages of labor or materials not attributable to Landlords failure to properly manage construction or procurement schedules and lead-times, war,
acts of terrorism, governmental laws, regulations or restrictions, or any other cause whatsoever beyond the control of Landlord or Tenant, as the case may be. Whenever a period of time is herein prescribed for the taking of any action by Landlord or
Tenant (other than the payment of Rent and all other such sums



27



---

of money as shall become due hereunder), such party shall not be liable or responsible for, there shall be excluded from the computation of such period of
time, any delays due to events of Force Majeure.



E. Except as expressly otherwise herein provided, with respect to all required acts of Tenant, time is of the essence of this Lease.



F. Landlord shall have the right to transfer and assign, in whole or in part, all of its rights and obligations hereunder and in the
Building and Property referred to herein, and in such event and upon such transfer Landlord shall be released from any further obligations hereunder, and Tenant agrees to look solely to such successor in interest of Landlord for the performance of
such obligations; provided, however no such transfer or assignment shall relieve Landlord from personal liability for the representations, warranties and undertakings set forth in Section 5.B of this Lease.



G. Tenant and Landlord hereby represent to each other that
it respectively has dealt directly with and only with the Broker as a broker in connection with this Lease. Landlord and Tenant hereby indemnify and hold each other harmless against any loss, claim, expense or liability with respect to any
commissions or brokerage fees claimed by any broker or finder other than the Broker on account of the execution and/or renewal of this Lease due to any action of the indemnifying party. Notwithstanding anything to the contrary hereinabove, Landlord
shall be solely responsible for the payment of any fees or commissions of the Broker as well as any broker employed or utilized by Great Lakes REIT or any other former owner of the Building to the extent any fee or commission is due any such other
broker.



H. If there is more than one Tenant,
or if Tenant as such is comprised of more than one person or entity, the obligations hereunder imposed upon Tenant shall be joint and several obligations of all such parties. All notices, payments, and agreements given or made by, with or to any one
of such persons or entities shall be deemed to have been given or made by, with or to all of them.



I. Tenant acknowledges that the financial capability of Tenant to perform its obligations hereunder is material to Landlord and that
Landlord would not enter into this Lease but for its belief, based on its review of Tenants financial statements, that Tenant is capable of performing such financial obligations. Tenant hereby represents, warrants and certifies to Landlord
that its financial statements previously furnished to Landlord fairly represent the financial condition of Tenant. In the event of a proposed sale or other transfer, financing or refinancing by Landlord of the Building, where the proposed lender or
purchaser requests tenant financial statements, within twenty (20) days after Landlords request, Tenant shall deliver to Landlord the most current year-end financial statements of Tenant and any guarantor of this Lease.



J. Except as otherwise expressly set forth in this Lease,
the expiration of the Lease Term, whether by lapse of time or otherwise, shall not relieve Tenant from Tenants



28



---

obligations accruing prior to the expiration of the Lease Term, and such obligations shall survive any such expiration or other termination of the Lease
Term.



K. Landlord and Tenant understand,
agree and acknowledge that (i) this Lease has been freely negotiated by both parties; and (ii) in any controversy, dispute or contest over the meaning, interpretation, validity, or enforceability of this Lease or any of its terms or conditions,
there shall be no inference, presumption, or conclusion drawn whatsoever against either party by virtue of that party having drafted this Lease or any portion thereof.



L. The headings and titles to the paragraphs of this Lease are for convenience only and shall have no affect
upon the construction or interpretation of any part hereof. The term including shall be deemed to mean including without limitation.



31. No Offer. Landlord has delivered a copy of this Lease to Tenant for Tenants review only, and the delivery hereof does not
constitute an offer to Tenant or an option. This Lease shall not be effective until an original of this Lease executed by both Landlord and Tenant and an original Guaranty, if applicable, executed by each Guarantor is delivered to and accepted by
Landlord, this Lease has been approved by Landlords mortgagee, if required, and the condition to the effectiveness of this Lease under Section 5.C, D, E and F have been satisfied or waived in writing.



32. Entire Agreement. This Lease, including the Exhibits
attached hereto, constitutes the entire agreement between the parties hereto with respect to the subject matter of this Lease and supersedes all prior agreements and understandings between the parties related to the Premises, including all lease
proposals, letters of intent and similar documents. Tenant expressly acknowledges and agrees that Landlord has not made and is not making, and Tenant, in executing and delivering this Lease, is not relying upon, any warranties, representations,
promises or statements, except to the extent that the same are expressly set forth in this Lease. This Lease may be modified only by a written agreement signed by Landlord and Tenant. Landlord and Tenant expressly agree that there are and shall be
no implied warranties of merchantability, habitability, suitability, fitness for a particular purpose or of any other kind arising out of this Lease, all of which are hereby waived by Tenant, and that there are no warranties which extend beyond
those expressly set forth in this Lease.



33. Limitation
of Liability. Notwithstanding anything to the contrary in this Lease, Landlord shall have personal liability for the representations, warranties and undertakings set forth in Section 5.B of this Lease. Any other liability of Landlord under
this Lease shall be limited solely to its interest in the Property, and in no such other event shall any personal liability be asserted against Landlord, its members, or their respective members, partners, shareholders, officers, directors, agents
or employees, in connection with this Lease nor shall any recourse be had to any other property or assets of Landlord, its members, or their respective members, partners, shareholders, officers, directors, agents or employees. In no event shall
either Landlord or Tenant be liable for consequential or punitive damages as a result of a breach or default under or otherwise in connection with this Lease, other than and excepting those payable as expressly set forth in Paragraph 23 of this
Lease.

EXHIBIT C



PAYMENT OF BASIC COSTS



A. During each calendar year, or portion thereof, falling within the Lease
Term, Tenant shall pay to Landlord as Additional Rent hereunder Tenants Pro Rata Share of Basic Costs (as defined below) and Tenants Pro Rata Share of Taxes (as defined below) for the applicable calendar year. Prior to the Commencement
Date, or as soon as practical thereafter, and prior to January 1 of each calendar year during the Lease Term, or as soon as practical thereafter, Landlord shall make a good faith estimate of Basic Costs and Taxes for the applicable full or partial
calendar year and Tenants Pro Rata Share thereof. On or before the first day of each month during such calendar year, Tenant shall pay Landlord, as Additional Rent, a monthly installment equal to one-twelfth of Tenants Pro Rata Share of
Landlords estimates of Basic Costs and Taxes. Landlord shall have the right from time to time during any such calendar year to reasonably revise the estimate of Basic Costs and/or Taxes for such year and provide Tenant with a revised statement
therefor (provided, however, Landlord agrees that Landlord shall not issue a revised statement more than once for Basic Costs and once for Taxes in any calendar year), and thereafter the amount Tenant shall pay each month shall be based upon such
revised estimate. If Landlord does not provide Tenant with an estimate of the Basic Costs and/or Taxes by January 1 of any calendar year, Tenant shall continue to pay a monthly installment based on the previous years estimate until such time
as Landlord provides Tenant with an estimate of Basic Costs and/or Taxes for the current year. Upon receipt of such current years estimate, an adjustment shall be made for any month during the current year with respect to which Tenant paid
monthly installments of Additional Rent based on the previous years estimate. Tenant shall pay Landlord for any underpayment within thirty (30) days after Landlords written demand. Any overpayment of Additional Rent shall, at
Tenants option, be refunded to Tenant or credited against the installment(s) of Additional Rent next coming due under the Lease. Any amount paid by Tenant based on any estimate shall be subject to adjustment pursuant to Paragraph C below when
actual Basic Costs or actual Taxes, as applicable, are determined.



B. If the Parking Deck is at any time made available for use by tenants of the Phase I Building or future tenants (other than Tenant), if any, of the Building, Tenant shall be given a credit against Tenants Pro-Rata Share of Basic
Costs for the portion of Basic Costs reasonably attributable to and reflecting such shared use of the Parking Deck.



C. As soon as is practical following the end of each calendar year during the Lease Term, Landlord shall furnish to Tenant a statement of Landlords
actual Basic Costs and Taxes for the previous calendar year. If for any calendar year the Additional Rent collected for the prior year, as a result of Landlords estimate of Basic Costs or Taxes, is in excess of Tenants actual Pro Rata
Share of Basic Costs or Taxes, as applicable, for such prior year, then Landlord shall refund to Tenant any overpayment (or at Tenants option apply such amount against Additional Rent due or to become due hereunder). Likewise, Tenant shall pay
to Landlord, within thirty (30) days after Landlords written demand, any underpayment with respect to the



C-1



---

prior year whether or not the Lease has terminated prior to receipt by Tenant of a statement for such underpayment, it being understood that this clause
shall survive the expiration of the Lease.



D. Basic
Costs shall mean all reasonable direct and indirect costs, expenses paid and disbursements of every kind (subject to the limitations set forth below), which Landlord incurs, pays or becomes obligated to pay in each calendar year in
connection with operating, maintaining, repairing, owning and managing the Building, the Parking Deck and the Property. Basic Costs shall include, without limitation, insurance premiums for insurance which is the obligation of Landlord under Section
13, and deductibles paid with respect to claims thereunder, and the amortized cost of capital improvements made to the Building or the Property which are (i) primarily for the purpose of reducing operating expense costs or otherwise improving the
operating efficiency of the Property or Building (but the amortized amount included in Basic Costs each year shall not exceed the amount of such savings); or (ii) required to comply with any laws, rules or regulations of any governmental authority
not in existence as of the date of this Lease or a requirement of Landlords insurance carrier. The cost of such capital improvements shall be amortized over the useful life thereof, as reasonably determined by Landlord in accordance with
generally accepted accounting principles, consistently applied, and shall, at Landlords option, include interest at a rate that is reasonably equivalent to the interest rate that Landlord would be required to pay (assuming, for this purpose,
that Landlord is creditworthy and the interest rate reflects such creditworthiness) to finance the cost of the capital improvement in question as of the date such capital improvement is performed.



E. Basic Costs shall not include the following:



| | (1) | leasing and sale commissions, fees and expenses;
| | --- | ------------------------------------------------



| | (2) | wages, benefits and other compensation for any employee above the grade of building manager;

F. Taxes shall mean (i) all real estate taxes and assessments on the Property, the Building or the Premises, and taxes and assessments levied in substitution or supplementation in whole or in part
of such taxes, (ii) all personal property taxes for the Buildings personal property, including license expenses, (iii) all taxes imposed on services of Landlords agents and employees, (iv) all sales, use or other tax, excluding state
and/or federal income tax now or hereafter imposed by any governmental authority upon rent received by Landlord, (v) all other taxes, fees or assessments now or hereafter levied by any governmental authority on the Property, the Building or its
contents or on the operation and use thereof (except as relate to specific tenants), and (vi) all reasonable costs and fees incurred in connection with seeking reductions in or refunds in Taxes including, without limitation, any costs incurred by
Landlord to challenge the tax valuation of the Building or Property, but excluding income taxes. Estimates of real estate taxes and assessments for any calendar year during the Lease Term shall be determined based on Landlords good faith
estimate of the real estate taxes and assessments. Taxes and assessments hereunder are those paid or payable for such calendar year, as opposed to the real estate taxes and assessments accrued with respect to such calendar year.



Notwithstanding the provisions of Paragraph F of this Exhibit C, Landlord and
Tenant acknowledge that, if and in the event an Exemption Certificate (defined below) is issued for the Property, Tenant shall be the tax payer and shall be responsible for the payment of those Taxes consisting of (i) all real estate taxes and
assessments on the Property, the Building, the Parking Deck or the Premises, and taxes and assessments levied in substitution or supplementation in whole or in part of such taxes, (ii) all personal property taxes for the Buildings personal
property, including license expenses, (iii) all other taxes, fees or assessments now or hereafter levied by any governmental authority on the Property, the Parking Deck, the Building or its

contents or on the operation and use thereof. Tenant plans to petition the City for the establishment of the leased premises under the Phase I Lease and the
Property as an industrial development district and to obtain real/personal property tax abatements pursuant to an industrial facilities exemption certificate (Exemption Certificate). In connection therewith, the parties acknowledge that
the Exemption Certificate would be issued in Tenants name, and that accordingly Tenant will be required to pay the foregoing identified portions of the Taxes. From and after the date of issuance of the Exemption Certificate, Tenant will be
billed by the City for and will pay directly any and all such taxes or payments in lieu thereof. If and in the event this Lease is terminated at any time prior to the Commencement Date, Landlord shall forthwith reimburse Tenant for the full amount
of all such taxes and other payments borne by Tenant under the Exemption Certificate through the date of termination. If the Parking Deck is at any time, made available for use by tenants of the Phase I Building or future tenants (other than
Tenant), if any, of the Building, Landlord shall reimburse Tenant, upon request, for the portion of Taxes and other payments borne by Tenant and reasonably attributable to and reflecting such shared use of the Parking Deck.

reasonable manner, during the thirty (30) day period following the delivery of Landlords statement of the actual amount of Basic Costs, such of Landlords books of account and records as pertain to and contain information concerning such
costs and expenses in order to verify the amounts thereof. Tenant agrees that any information obtained during an inspection by Tenant of Landlords books of account and records shall be kept in confidence by Tenant and its agents and employees
and shall not be disclosed to any other parties, except to Tenants attorneys, accountants and other consultants. If Tenant shall not dispute any item or items included in the determination of Basic Costs for a particular Lease Year by
delivering a written notice to Landlord generally describing in reasonable detail the basis of such dispute within sixty (60) days after the statement for such year was delivered to it, Tenant shall be deemed to have approved such statement. During
the pendency of any dispute over Basic Costs, Tenant shall pay, under protest and without prejudice, Tenants Pro Rata Share of Basic Costs as calculated by Landlord. Tenant shall bear the cost of its accountants or other consultants employed
by Tenant undertaking any review of Basic Costs; provided, however, that in the event the review reveals an overcharge (by error or otherwise) of actual (as distinguished from estimated) Basic Costs in excess of five percent (5%) of the total Basic
Costs, Landlord shall pay the reasonable out of pocket cost of the review (up to the amount of the overcharge).



H. Solely for the benefit of Tenant and not for the benefit of any other tenant or third-party, Operating Expenses (as defined below) for any
calendar year (the Applicable Calendar Year) following the calendar year in which the Commencement Date occurs (the Commencement Year), commencing with the second Applicable Calendar Year, shall not exceed an amount
determined by increasing the Operating Expenses for the first Applicable Calendar Year (the Base Expenses) at the rate of four percent (4%) per year cumulative interest through the Applicable Calendar Year. Notwithstanding the foregoing,
relative to the fifth Applicable Calendar Year, and the Applicable Calendar Year falling every five years thereafter, the Base Expenses shall be adjusted to be an amount equal to the product of (x) the average of the actual Operating Expenses for
the three prior Applicable Calendar Years, multiplied by (y) 1.0816. Operating Expenses shall mean the Basic Costs, exclusive of (i)



C-5



---

Taxes, or (ii) Basic Costs incurred by virtue of an increased scope of services mutually agreed to by Landlord and Tenant (in advance of implementation).
Such limitation on Operating Expenses shall not limit or otherwise affect Tenants obligations regarding the payment of any other component of Rent under this Lease.



I. Notwithstanding anything to the contrary contained in this Lease, the Basic Costs charged to Tenant during the
Commencement Year shall not exceed $7.20 per rentable square foot per year (such amount to be prorated based on the number of days in the Commencement Year).

layout, drawings, or plans within five (5) Business Days after written request. Any disapproval shall be in writing and shall set forth in reasonable detail the reasons for such disapproval. Landlord shall have ten (10) Business Days from its
receipt of Tenants disapproval within which to revise the layout, drawings or plans to address the matters identified by Tenant to Tenants satisfaction. Tenant and Landlords Architect shall devote such time in consultation with
Landlord and Landlords engineer as may be required to provide all information Landlord deems necessary in order to enable Landlords Architect and engineer to complete, and obtain Tenants written approval of the Plans for
Landlords Work by not later than June 1, 2005 (the Plans Due Date). The Plans Due Date shall be extended for any failure by Landlord to so timely respond to Tenants objections and provide revised layouts, drawings or

approve the Plans by the Plans Due Date (as the same may be extended for delays by Landlord), Tenant shall be responsible for one (1) day of Delay (as hereinafter defined) for each day during the period beginning on the day following the Plans Due
Date and ending on the date Tenant approves the Plans. Neither the approval of the Plans nor the supervision of Landlords Work by Landlord shall constitute a representation or warranty by Landlord as to the accuracy, adequacy, sufficiency and
propriety of the Plans or the quality of workmanship or compliance of Landlords Work with applicable law.

|5. | Prior to commencing any construction of Landlords Work, Landlord shall submit to Tenant a written estimate setting forth the anticipated cost of Landlords Work,
including but not limited to labor and materials, architects fees, contractors fees and permit fees. Within three (3) Business Days thereafter, Tenant shall either notify Landlord in writing of its approval of the cost estimate, or
specify its objections thereto in reasonable detail and any desired changes to the proposed Landlords Work. In the event Tenant notifies Landlord of such objections and desired changes, Tenant shall work with Landlord in good faith to alter
the scope of Landlords Work in order to reach a mutually acceptable alternative cost estimate, and Tenant shall not be responsible for any Delay resulting therefrom.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Landlords Work and presentation of an invoice therefor by Landlord. Notwithstanding the foregoing, if such Excess Costs are in excess of $10.00 per
rentable square foot of the Premises, then Tenant shall pay to Landlord such Excess Costs within ten (10) days after Tenants receipt of Landlords invoice together with all necessary and/or appropriate back-up documentation of such Excess
Costs. Landlord shall not be required to proceed with Landlords Work until Tenant pays such Excess Costs and any delay in the completion of Landlords Work due to a delay by Tenant in making such payment shall be deemed a Delay pursuant
to this Lease. The statements of costs submitted to Landlord by Landlords contractors shall be conclusive for purposes of determining the actual cost of the items described therein. Excess Costs constitute Rent payable pursuant to the Lease,
and the failure to timely pay same constitutes an Event of Default under the Lease.

|7. | If Tenant shall request any changes to Landlords Work that are approved by Landlord (Change Orders), Landlord shall have any necessary revisions to the
Plans prepared, and Tenant shall reimburse Landlord on demand for the cost of preparing such revisions. Landlord shall notify Tenant in writing of the estimated increased cost, if any, which will be chargeable to Tenant by reason of such Change
Orders, which increased cost shall be included in the calculation determining whether there are Excess Costs under Paragraph 6 above. Tenant shall, within three (3) Business Days after receiving Landlords estimate of the cost of the Change
Order, notify Landlord in writing whether it desires to proceed with such Change Order. In the absence of such written authorization within said time period, Landlord shall have the option to continue work on the Premises disregarding the requested
Change Order, or Landlord may elect to discontinue work on the Premises until it receives notice of Tenants decision, in which event Tenant shall be responsible for any Delay in completion of Landlords Work resulting therefrom.

|8. | Following approval of the Plans, and the payment by Tenant of the required portion of the Excess Costs, if any, Landlord shall promptly commence and thereafter diligently pursue to
completion Landlords Work in accordance with the approved Plans, so long as no default shall occur under the Lease, and in any event shall Substantially Complete Landlords Work on or before the Target Commencement Date, subject only to
Delays (as defined below). Landlord shall notify Tenant upon Substantial Completion of Landlords Work.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | If Landlord shall be delayed in Substantially Completing Landlords Work as a result of the occurrence of any of the following (a Delay); provided, however,
that in any such case (i) Landlord shall provide written notice of and back-up documentation supporting such claim of Delay promptly (but in no event later than 5 days) after the occurrence of the Delay, and (ii) an actual delay in Substantial
Completion occurs as a result of such Delay:

| | (a) | Tenants failure to timely furnish information to complete the Plans, or otherwise in accordance with this Work Letter, or to respond to any request by Landlord for any
approval or information within any time period prescribed, or if no time period is prescribed, then within three (3) Business Days of such request; or

| | (b) | Tenants request after initial approval of the Base Building Plans and Specifications or the Plans, as the case may be, for different materials, finishes or installations that
have long lead times after having first been informed by Landlord that such materials, finishes or installations will cause a Delay; or
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Changes in any plans and specifications requested by Tenant if Landlord advises Tenant such changes shall cause a Delay and Tenant elects to proceed with such changes; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | The performance or nonperformance by a person or entity employed by on or behalf of Tenant in the completion of any work in the Premises (all such work and such persons or entities
being subject to prior approval of Landlord), provided that such performance or nonperformance has an actual demonstrable effect on the schedule for Substantial Completion; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Any request by Tenant that Landlord delay the completion of any component of Landlords Work if Landlord advises Tenant that such delay shall cause a Delay and Tenant elects to
proceed with such request; or

that such action shall cause a Delay and Tenant elects to proceed with taking possession; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | Any other delay chargeable to Tenant, its agents, employees or independent contractors; provided that such delay has an actual effect on the schedule for Substantial Completion;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



then, for purposes of
determining the Commencement Date, the date of Substantial Completion shall be deemed to be the day that Landlords Work would have been Substantially Completed absent any such Delay. The adjustment of the Commencement Date and, accordingly,
the postponement of Tenants obligation to pay Base Rent and other sums due under the Lease shall be Tenants sole remedy that Tenant might otherwise have against Landlord by reason of the Premises not being ready for occupancy by Tenant
on the Target Commencement Date, except as otherwise provided in Section 5 of this Lease. Promptly after the determination of the Commencement Date, Landlord and Tenant shall enter into a letter agreement (the Commencement Letter)on the form attached to the Lease as ExhibitF setting forth the Commencement Date, the Expiration Date and any other dates that are affected by the adjustment of the Commencement Date. The Commencement Letter shall identify any
minor incomplete

items of Landlords Work as reasonably determined by Landlords architect (the Punchlist Items), which Punchlist Items Landlord
shall promptly remedy. Tenant, within five (5) days after receipt thereof from Landlord, shall execute the Commencement Letter and return the same to Landlord.

|11. | Tenant shall perform all work (other than Landlords Work) in accordance with the terms of this Work Letter as required to put the Premises in a condition to permit the conduct
of Tenants business therein and in accordance with the requirements of this Lease. When Landlords Work has proceeded to the point where the work to be performed by Tenant and the installation of Tenants Property in the Premises
(collectively Tenants Work) can, in the opinion of Landlord, be commenced in accordance with good construction practice, then Tenant shall have the right to occupy the Premises for the purpose of performing Tenants Work so
far as its occupancy is not inconsistent with Landlords Work or any work to be done in the Building by Landlord, subject to all the terms and condition of this Lease (including in particular Section 9B), except that the Term of this Lease
shall not commence until the Commencement Date. Tenant acknowledges that entry onto the Premises when the Landlords Work is not Substantially Complete entails a risk of bodily injury, death, or damage, destruction, loss or misappropriation of
property. To the extent not expressly prohibited by law, Tenant hereby assumes all such risks for entry onto the Premises, and agrees to defend and hold harmless Landlord (its agents, contractors, and employees) against all costs and expenses,
including reasonable attorneys fees in connection therewith, arising out of any bodily injury, death, or damage, destruction, loss or misappropriation of property related to entry onto the Premises by Tenant or its agents, employees,
contractors, invitees or subtenants prior to such time as the Landlords Work is substantially complete, except to the extent such costs or expenses arise out of the negligence or willful misconduct of Landlord, its contractors, subcontractors,
employees, agents or representatives. Tenant shall be solely responsible to determine at the site all dimensions of the Premises and the Building which affect any work to be performed by Tenant hereunder. The installation of Tenants Property
into the Premises shall be the sole responsibility of Tenant, and any costs associated therewith shall be borne by Tenant. Neither review nor approval by Landlord of any plans or specifications for Tenants Work or any other work to be
performed by Tenant shall constitute a representation or warranty by Landlord that any of such plans or specifications either (i) are complete or suitable for their intended purpose, or (ii) comply with applicable laws, ordinances, codes and
regulations.

|12. | If the actual Phase II Project Costs are less than Twenty Million Dollars ($20,000,000.00), Tenant shall be entitled to receive the difference in such amounts (the
Savings). The Savings shall be paid to Tenant in the form of (i) cash payment to Tenant, and/or (ii) abatement of Base Rent and/or Additional Rent, and/or (iii) reduction of Base Rent over all or any portion of the Lease Term, such
determination to be made in Landlords sole discretion. Within ninety (90) days after the Commencement Date, Landlord shall deliver to Tenant a statement in sufficient detail summarizing the Phase II

ADDITIONAL PROVISIONS



1. Parking. Tenant, and its employees, guests and invitees, shall have the
exclusive right to utilize the enclosed lower level parking (approximately 37 spaces) to be constructed within the Building, as well as the non-exclusive right to use the Parking Deck (700 spaces). The parties acknowledge that the required parking
ratio for the Premises is based on four (4) spaces per 1,000 rentable square feet, or an aggregate for the Premises under this Lease of 441. Tenant agrees that surplus parking spaces in the Parking Deck over those required for the Premises will be
utilized by Tenant, and other tenants in the Phase I Building, to fulfill a portion of the parking requirements under the Phase I Lease.



2. Option to Renew.



A. Tenant shall have the option (but shall not be required) to extend the Lease Term with respect to all (but not less than all) of the Premises for two
(2) additional periods of five (5) years, each (the Extension Term(s)). Tenant may elect to exercise such option(s) by written notice received by Landlord not less than eighteen (18) months prior to the expiration of the Lease Term, or
the first Extension Term, as the case may be, time being of the essence for the giving of such notice. During the Extension Term(s), the Lease will continue on the terms and conditions set forth herein, other than the Base Rent, which shall be
adjusted to the current Market Rental Rate for the Premises as of the date the applicable Extension Term is to commence with appropriate increases each year thereafter.



B. Landlord shall advise Tenant of the Market Rental Rate for the applicable Extension Term within twenty (20) days after
the earlier of (i) a request therefore from Tenant, or (ii) Landlords receipt of Tenants notice exercising a renewal option. Tenants failure to timely make such request shall not extend the date upon which Tenant must give notice
of its exercise of the option to renew. Tenant shall have twenty (20) days from the receipt of Landlords notice to either accept or dispute Landlords determination of the Market Rental Rate. In the event that Tenant disputes
Landlords determination, Tenant shall so notify Landlord and advise Landlord of Tenants determination of the Market Rental Rate for the Renewal Term. If, after engaging in good faith negotiations, Landlord and Tenant cannot agree upon
the Market Rental Rate within thirty (30) days after Landlords receipt of Tenants notice of objection to Landlords determination of the Market Rental Rate, the Dispute Resolution Mechanism described in subparagraph C
below shall apply.



C. The Dispute Resolution Mechanism shall
be as follows: no later than fifteen (15) days after the end of the 30-day period described in subparagraph B above, Landlord and Tenant shall jointly appoint as arbitrator a commercial real estate broker licensed in Michigan with a minimum of five
(5) years experience in the applicable office market. If Landlord and Tenant



E-1



---

cannot agree on an acceptable arbitrator, Landlord and Tenant shall each choose, within an additional fifteen (15) days thereafter, its own arbitrator who
meets the qualifications described above. The arbitrators shall then jointly select, within an additional ten (10) days, an arbitrator to serve as the arbitrator hereunder. If either Landlord or Tenant fails to choose its own arbitrator within said
fifteen (15) day period, then the arbitrator chosen by the other shall resolve the dispute. Within ten (10) days after appointment (whether mutually by the parties, by default of one party to choose an arbitrator, or by selection by the two
arbitrators), Landlord and Tenant shall each submit to the arbitrators) in writing its good faith estimate of the Market Rental Rate for the Extension Term. Within ten (10) days after receipt of the last of the determinations, the arbitrators) shall
choose either Landlords or Tenants determination of Market Rental Rate. The cost of the arbitrator(s) shall be borne by the party whose determination of the Market Rental Rate was not selected by the arbitrator.



D. Tenants exercise of the foregoing option to renew is subject to the
conditions that (i) the Lease is in full force and effect, (ii) Tenant is not in default hereunder beyond any applicable notice or cure period at the time of notification or at any time after notification and through commencement of the Renewal
Term, (iii) neither the Premises nor any part thereof have been sublet (other than a Permitted Transfer), (iv) Tenant has not assigned the Lease (other than a Permitted Transfer), (v) Tenant is an occupant of the Premises under this Lease and
intends to continue to use the Premises itself, and (vi) that both at the time of notification and commencement there has been no material adverse change in the financial condition of the Tenant since the date of the Lease, as reasonably determined
by Landlord.



E. For purposes of this Lease, Market
Rental Rate shall mean the rental, as of the date for which such Market Rental Rate is being calculated, per annum per rentable square foot, for lease renewals for comparable space of comparable size, which Landlord is offering or prepared to
offer for renewals in good faith at that time to third parties for a similar term for such other space in the Building, as well as in other comparable buildings within a five (5) mile radius of the Property, taking into account prevailing market
conditions.



F. Landlord shall have no obligation to make
improvements, decorations, repairs, alterations or additions to the Premises as a condition to Tenants obligations to pay Rent during the Extension Term(s) unless otherwise agreed to by the parties at the time the amendment set forth below is
executed, other than those repairs, maintenance and/or replacements as may otherwise be the responsibility of Landlord under this Lease. In the event that Tenant exercises the renewal option(s) set forth herein, Landlord and Tenant agree to enter
into an amendment to the Lease incorporating the applicable Extension Term and the Annual and Monthly Base Rent applicable thereto within sixty (60) days following the exercise of the applicable renewal option, but in no event shall a delay in the
full execution of such amendment nullify Tenants exercise of the option to renew.

3. Lower Level Space.



A. Subject to and upon the terms set forth in this Lease, in addition to the Premises, Tenant shall also lease from Landlord
and Landlord shall lease to Tenant during the Lease Term the Lower Level Space. Commencing on the Commencement Date of this Lease, but following the Free Rent Period, Tenant shall pay Landlord an annual rental rate of $12.00 per square foot,
escalating two percent (2%) per Lease Year (the Lower Level Rental Rate)for the use of the Lower Level Space, and without any obligation to pay Additional Rent for the Lower Level Space. The Lower Level Space shall not be
utilized in the calculation of the Rentable Area in the Premises, or Tenants Pro Rata Share. The Lower Level Rental Rate shall be paid monthly in advance simultaneously with the payment of Base Rent. At all times during the term of the Lease,
Tenant shall be directly responsible for the payment of all electrical and other utility services to the Lower Level Space.



B. Landlord shall provide up to but not in excess of $20.00 per square foot in the Lower Level Space (Lower Level Allowance)for
Tenants use for the purpose of performing improvements and alterations to the Lower Level Space, provided that the Lower Level Allowance shall only apply to those portions of the Lower Level Space for which Landlord or Tenant has received City
approvals for occupancy. No work may be performed prior to Landlords written approval of such work and/or the detailed plans of such work, if necessary and available. Any contractors performing work in the Lower Level Space that are not
contracted through Landlord shall be subject to Landlords prior approval. If the cost of such work to the Lower Level exceeds the amount of the Lower Level Allowance, Tenant shall be directly responsible for said excess amount or shall pay to
Landlord said excess amount within ten (10) days of Tenants receipt of Landlords statement of such excess costs.



C. Except as otherwise provided herein, all of the terms and provisions of the Lease shall also apply to the Lower Level Space as if it were part of the
Premises.



D. The terms and conditions of this Paragraph 3 are
conditioned on Landlord or Tenant receiving the necessary City approvals for the use and occupancy of the Lower Level Space, or portions thereof. Tenant shall be obligated to pay the Lower Level Rental Rate as of the Commencement Date, but only for
those portions of the Lower Level Space for which Landlord or Tenant has received City approvals for occupancy. Landlord and Tenant shall use commercially reasonable efforts to obtain City approvals for the use and occupancy of the Lower Level Space
on the terms set forth herein. The area of Lower Level Space so leased hereunder, from time to time, may be re-measured at the request of either party, and verified by the other party.
