Operating Expenses (and any special allocation of Variable Operating Expenses) for that Calendar Year in excess of the Base Year and shall deliver to Tenant a statement of the Expense Adjustment Amount plus a statement of all estimated installments
paid by Tenant with respect to that Calendar Year. Tenant shall pay to Landlord any deficiency shown by the statement within thirty (30) days after Tenant receives the statement. If the installments paid exceed the amount due, Landlord shall

Landlord shall apply the difference first to any delinquent Rent hereunder (including interest thereon) and then to the next succeeding payments of Rent coming due hereunder. The foregoing obligations of Landlord and Tenant shall survive the
expiration of the Term until final determination of Operating Expenses and Taxes attributable to Tenants tenancy during the final Lease Year and payment thereof, if due and owing. Delay in computation of the Expense Adjustment Amount shall not
be deemed a default hereunder or a waiver of Landlords right to collect the Expense Adjustment Amount. Landlord shall cause to be kept books and records showing Operating Expenses in accordance with an appropriate system of accounts and
accounting practices consistently maintained. Tenant shall have the right to audit,

Expenses of any Calendar Year or portion thereof commencing after the Base Year and falling within the Term. The cost of such audit shall be borne by Tenant unless, in connection with any audit conducted by Tenant, it is demonstrated that Landlord
has overstated Tenants Expense Adjustment Amount by five percent (5%) or more, in which case Landlord shall bear the cost of such audit, provided, however, Landlord shall not be obligated to pay greater than $2,500.00 for such audit.
Notwithstanding anything contained in the preceding sentence to the contrary, any audit by Tenant of Operating Expenses for any such Calendar Year must be requested within sixty (60) days following the date of Tenants receipt of
Landlords statement of Operating Expenses and completed within one hundred twenty (120) days following the date on which Landlord makes such books and records available to Tenant. Tenants accountants shall be required to execute a
confidentiality agreement and shall conduct the audit at the office of the Building at such times that are designated by Landlord.

| | (c) | Allocation of Variable Operating Expenses. If at any time during the Term less than ninety-five percent (95%) of the then current office space in the
Building is occupied, at Landlords option those components of Operating Expenses which vary with occupancy (Variable Operating Expenses) shall be removed from general Operating Expenses and allocated to the portion of the
office space in the Building which is actually occupied and generating such components of Operating Expenses. This special allocation shall be made on a pro rata basis in accordance with Tenants Proportionate Share over the occupied office
space in the Building, based on both the comparative Rentable Areas of the Building which are occupied and the portion of the Calendar Year during which the portions of the Building were occupied. Examples of Variable Operating Expenses include,
without limitation, janitorial services, electricity for overhead lighting and HVAC costs. Operating Expenses which do not vary with occupancy, such as public liability insurance and lobby maintenance will continue to be allocated on a pro rata
basis over the office space in the Building whether or not occupied, and Tenant shall only be responsible for Tenants Proportionate Share of those Operating Expenses. Tenants obligation to pay its Proportionate Share of Operating
Expenses and Variable Operating Expenses shall not exceed what Tenant would otherwise be obligated to pay if the office space portion of the Building was fully leased.

Base Year. The Tax Adjustment Amount with respect to each Calendar Year starting in 2012 shall be paid in monthly installments during that Calendar Year in an amount reasonably estimated from time to time by Landlord and communicated by written
notice to

| | Tenant. Following the final determination of Taxes for each Calendar Year, Landlord shall compute the Tax Adjustment Amount for that Calendar Year and deliver to Tenant a statement of the Tax
Adjustment Amount plus a statement of all estimated installments paid by Tenant for that Calendar Year. Tenant shall pay to Landlord any deficiency shown by the statement within thirty (30) days after Tenant receives the statement. If the
installments paid exceed the actual amount due, Landlord shall either credit the excess against Rent or any other payment next due to Landlord from Tenant hereunder or at Landlords option, and if Tenant is not then in Default hereunder, refund
the excess to Tenant. If Tenant is then in Default hereunder, Landlord shall apply the difference first to any delinquent Rent hereunder (including interest thereon) and then to the next succeeding payments of Rent coming due hereunder. The amount
of any refund of Taxes received by Landlord, less fees incurred in obtaining such refund, shall be credited against Taxes for the year in which such refund is received. The foregoing obligations of Landlord and Tenant shall survive the expiration of
the Term until Taxes attributable to the final Lease Year hereunder are determined and Tenant pays any sums due and owing. In determining the amount of Taxes for any Calendar Year, the amount of special assessments to be included shall be limited to
the amount of the installment (plus any interest payable thereon) of the special assessment required to be paid during that year as if Landlord had elected to have the special assessment paid over the maximum period of time permitted by law. All
references to Taxes for a particular year shall be deemed to refer to Taxes levied or assessed for the year without regard to when such Taxes are paid or payable. Delay in computing the Tax Adjustment Amount shall not be deemed a Default
hereunder or a waiver of Landlords right to collect the Tax Adjustment Amount.

follows: March, 2011, April, 2011, March, 2012, April, 2012, March, 2013 and March, 2014.

charge in an amount equal to with respect to regularly scheduled monthly payments of Base Rent, Expense Adjustment Amounts, Tax Adjustment Amounts or any other unpaid monetary item, 5% of the delinquent portion of any such payment. The provision for
such late charge shall be in addition to all of Landlords other rights and remedies under this Lease or at law or in equity. In particular, the foregoing late charge is in addition to, and not in lieu of the Default Rate set forth in

fee within twenty (20) days after being billed therefore. Landlord may, but shall not be required to, enter the Premises at all reasonable times to make such repairs, alterations, improvements, installations and additions to the Premises or to
the Building or to any equipment located in the Building as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental authority or court order or decree.

|8. | ADDITIONS AND ALTERATION
|-- | ------------------------



| | (a) | Except with respect to (i) the Work described in the Tenant Work Letter, (ii) minor painting, installation of carpeting, the moving of
furniture or the hanging of wall coverings or artwork, and (iii) nonstructural alterations, improvements, installations or additions costing less than $10,000 in the aggregate, Tenant shall not, without the prior written consent of Landlord,
make any alterations, improvements, installations or additions to the Premises, which shall include, without limitation, installing telephone, computer or internal sound or paging systems or other similar systems or performing any decorating,
painting or other similar work in the Premises. Landlords consent shall not be unreasonably withheld so long as such alterations, improvements, installations

| | and additions are consistent with the permitted uses of the Premises set forth in the Schedule hereof and do not adversely affect the mechanical, electrical, plumbing, HVAC or structural
components or common systems of the Building. In addition, Tenant shall have the right, without Landlords consent, to replace its telephone, computer, internal sound and paging systems during the Term of the Lease so long as there is no
structural work required in the Building or Premises. If Landlord consents to any alterations, improvements, installations or additions, it may impose such conditions with respect thereto as Landlord deems appropriate, including, without limitation,
requiring Tenant to furnish Landlord with security for the payment of all costs to be incurred in connection with such work, insurance against liabilities which may arise out of such work, plans and specifications plus permits necessary for such
work and, following completion, as-built drawings showing the actual location of the alterations, improvements, installations and additions. The work necessary to make any alterations, improvements, installations or additions to the
Premises, whether prior to or subsequent to the Commencement Date shall be done at Tenants expense by contractors selected from a list of contractors preapproved by Landlord. Tenant shall promptly pay to Landlord or the Tenants
contractors, as the case may be, when due, the cost of all such work plus, in all cases other than decorating or redecorating, a coordination fee payable to Landlord in connection with each such improvement, installation, alteration and/or addition
equal to five percent (5%) of the actual total cost of any such improvement, installation, alteration or addition, provided, however, Landlord shall not charge a coordination fee in connection with Tenants installation of supplementary
air conditioning units in the Premises. Tenant shall pay such costs and fee within twenty (20) days after being billed therefore.

| | (b) | All alterations, improvements, installations and additions to the Premises, whether temporary or permanent in character, made or paid for by Landlord or Tenant,
shall without compensation to Tenant become Landlords property at the termination of this Lease by lapse of time or otherwise and shall, unless Landlord is entitled to and does request their removal (in which case Tenant shall remove the same
as provided in Section 16), be relinquished to Landlord in good condition, ordinary wear and damage resulting from fire or other casualty excepted.

|9. | COVENANT AGAINST LIENS
|-- | ----------------------

Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon
Landlords title or interest in the Land, Building or Premises, and any and all liens and encumbrances created by Tenant shall attach to Tenants interest only. Tenant covenants and agrees not to suffer or permit any lien of mechanics or
materialmen or others to be placed against the Land, Building or Premises or any improvement in the Premises (whether installed or paid for by Landlord or Tenant) with respect to work or services claimed to have been performed for or materials
claimed to have been furnished to Tenant or the Premises and, if any such lien attaches or a claim for a lien is asserted,



18



---

Tenant covenants and agrees to cause it to be immediately released and removed of record; provided, however, that if such lien is being contested in good faith by Tenant by appropriate
proceedings diligently pursued, Tenant shall not be in default hereunder if Tenant shall, in a manner subject to Landlords prior written approval (which approval may be withheld arbitrarily) cause such lien or claim of lien to be insured over
by a title insurance company selected by Landlord (which title insurance shall, in any event, inure to the benefit of Landlord, Landlords mortgagees and any potential purchasers of the Land or Building of which Tenant shall be notified), and
provided that, in any event, such lien or claim of lien shall be released or removed within four (4) months of the date such lien first attached. If such lien is not immediately released and removed or insured over as aforesaid, Landlord, at
its sole option, may take all action necessary to release and remove such lien (without any duty to investigate the validity thereof) and Tenant shall promptly upon notice reimburse Landlord for all sums, costs and expenses (including reasonable
attorneys fees) incurred by Landlord in connection with such lien.

Notwithstanding anything in this Lease to the
contrary, Tenant covenants and agrees not to suffer or permit any equipment lien to attach to any of the fixtures or improvements in the Premises, whether installed and/or paid for by Landlord or Tenant.



|10. | INSURANCE
|--- | ---------



| | (a) | Waiver of Subrogation. Landlord and Tenant each hereby waive any and every claim for recovery from the other for any and all loss of or damage to the
Building or Premises or to the contents thereof, which loss or damage is covered by valid and collectible physical damage insurance policies, it being understood and agreed that the foregoing waiver shall also apply to the deductible under any such
policy. Landlord waives any and every claim against Tenant for any and all loss of or damage to the Building or the Premises or the contents thereof which would have been covered had the insurance policies required to be maintained by Landlord by
this Lease been in force, to the extent that such loss or damage would have been recoverable under such insurance policies. Tenant waives any and every claim against Landlord for any and all loss of or damage to the Building or the Premises or the
contents thereof which would have been covered had the insurance policies required to be maintained by Tenant by this Lease been in force, to the extent that such loss or damage would have been recoverable under such insurance policies. Inasmuch as
this mutual waiver will preclude the assignment of any such claim by subrogation (or otherwise) to an insurance company (or any other person), Landlord and Tenant each agree to give to each insurance company which has issued, or in the future may
issue, to it policies of physical damage insurance, written notice of the terms of this mutual waiver, and to have said insurance policies properly endorsed, if necessary, to prevent the invalidation of said insurance coverage by reason of said
waiver.

| | (b) | Coverage. Tenant shall purchase and maintain insurance during the entire Term for the benefit of Tenant and Landlord (as their interest
may appear) with terms, coverages and in companies reasonably satisfactory to Landlord, and with such increases in limits as Landlord may from time to time reasonably request, but initially Tenant shall maintain the following coverages in the
following amounts:
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



19



---

| | (i) | Commercial General Liability Insurance naming Landlord, Landlords managing agent and any mortgagees designated by Landlord as additional insureds, with coverage
for premises/operations, personal and advertising injury, products/completed operations and contractual liability with limits of liability of $1,000,000 for bodily injury and property damage per occurrence and $2,000,000 aggregate coverage and an
excess umbrella liability coverage of $5,000,000 per occurrence and in the aggregate.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Property Insurance covering the Work and all other Tenant improvements in the Premises, office furniture, trade fixtures, office equipment, merchandise and all other
items of Tenants property on the Premises, which insurance shall, with respect only to the Work and other Tenant improvements, name Landlord, and any mortgagees designated by Landlord as additional insureds as their interests may appear. Such
insurance shall be written on an all risks of physical loss or damage basis including but not limited to the perils of fire, extended coverage, windstorm, vandalism, malicious mischief, sprinkler leakage, flood and earthquake, for the
full replacement cost value of the covered items and in amounts that meet any co-insurance clause of the policies of insurance with a deductible amount not to exceed $10,000.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Workers Compensation Insurance with statutory benefits and Employers Liability Insurance with the following amounts: Each Accident -$500,000; DiseasePolicy
Limit$500,000; DiseaseEach Employee -$500,000.
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Tenant shall, prior to the commencement of the Term
and on each anniversary of the Commencement Date, furnish to Landlord certificates evidencing such coverage, which certificates shall state that such insurance coverage may not be changed or cancelled without at least thirty (30) days prior
written notice to Landlord and Tenant. The insurance maintained by Tenant shall be deemed to be primary insurance and any insurance maintained by Landlord shall be deemed secondary thereto.



| | (c) | Avoid Action Increasing Rates. Tenant shall comply with all applicable laws and ordinances, all orders and decrees of court and all requirements of other
governmental authorities, and shall not, directly or indirectly, make any use of the Premises which may thereby be prohibited or be dangerous to person or property or which may jeopardize any insurance coverage or may increase the cost of insurance
or require additional insurance coverage. If Tenant fails to comply with the provisions of this Section 101 and: (i) any insurance coverage is jeopardized and Tenant fails to correct such dangerous or prohibited use following notice
within the applicable cure period set forth in Section 22 hereof; or (ii) insurance premiums are increased and Tenant fails, following notice, to cease such use within the applicable cure period set forth in Section 22
hereof, then in each event such failure shall constitute a Default by Tenant hereunder and Landlord shall have all of its remedies as set forth in this Lease.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|11. | FIRE OR CASUALTY
|--- | ----------------



| | (a) | Section 7 hereof notwithstanding, if the Premises or the Building (including machinery or equipment used in its operation) shall be damaged by fire
or other casualty and if such damage does not cause a termination of this Lease as described in the following sentences, then Landlord shall repair and restore the damage with reasonable promptness, subject to reasonable delays for insurance
adjustments and delays caused by matters beyond Landlords reasonable control, but Landlord shall not be obligated to expend for repairing or restoring the damage an amount in excess of the proceeds of insurance recovered with respect to the
damage. If in Landlords estimate the Premises cannot be restored within three hundred sixty-five (365) days from the date of such fire or casualty, then Landlord shall give notice to Tenant of such estimate within ninety (90) days
after such fire or casualty and Tenant may elect in writing within sixty (60) days following the date of such notice from Landlord to terminate this Lease effective as of the date of Tenants notice. If any such damage: (i) renders
three (3) or more floors of the Building untenantable; or (ii) renders general Building systems inoperable and such systems cannot be repaired in Landlords reasonable estimate within two hundred seventy (270) days from the date
of such damage, or (iii) occurs within the last two (2) Lease Years, Landlord shall have the right to terminate this Lease as of the date of such damage upon giving written notice to the Tenant at any time within one hundred twenty
(120) days after the date of such damage. Tenant shall have the right to terminate this Lease if the Premises are not substantially restored within two hundred seventy (270) days after a fire or casualty. Notwithstanding the foregoing, in
the event Landlord elects to terminate the Lease because the casualty occurs during the last two (2) Lease Years, and Tenant elects to exercise its option to extend the Term as provided in Section 31hereof within ten (10) days
after receipt of Landlords notice, then, the Lease shall not be deemed to be terminated by Landlord. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease, by virtue of any delays in completion of
such repairs and restoration. Rent, however, shall abate on those portions of the Premises as are, from time to time, untenantable as a result of such damage.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Notwithstanding anything to the contrary herein set forth, Landlord shall have no duty pursuant to this Section 11 to repair or
restore any portion of the Work or any other alterations, additions, installations or improvements in the Premises or the decorations thereto except to the extent that the proceeds of the insurance carried by Tenant are timely received by Landlord.
If Tenant desires any other or additional repairs or restoration, and if Landlord consents thereto, it shall be done at Tenants sole cost and expense subject to all of the provisions of Sections 7 and 8 hereof. Tenant
acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage, whether carried by Landlord or Tenant, for damage to Tenants Work or any other alterations, additions, installations, improvements or decorations
which would become Landlords property upon the termination of this Lease, provided, however, insurance proceeds specifically allocated to Tenants

| | ------------------------------------------------------------------------------------------------



|12. | WAIVER OF CLAIMS  INDEMNIFICATION
|--- | ----------------------------------

To the extent not prohibited by law and subject to the waiver of subrogation contained in Section 10(a), Landlord and its partners, affiliates, officers, agents, servants and employees shall
not be liable for any damage either to person, property or business or resulting from the loss of use thereof sustained by Tenant or by other persons due to the Building or any part thereof or any appurtenances thereto becoming out of repair, or due
to the happening of any accident or event in or about the Building, including the Premises, or due to any act or neglect of any tenant or occupant of the Building or of any other person, unless caused by the negligence or willful misconduct of
Landlord or its agents, employees or contractors. This provision shall apply particularly, but not exclusively, to damage caused by gas, electricity, snow, ice, frost, steam, sewage, sewer gas or odors, fire, water or by the bursting or leaking of
pipes, faucets, sprinklers, plumbing fixtures and windows, and, except as provided above, shall apply without distinction as to the person whose act or neglect was responsible for the damage and shall apply whether the damage was due to any of the
causes specifically enumerated above or to some other cause of an entirely different kind. Tenant further agrees that all personal property upon the Premises, or upon loading docks, receiving and holding areas, or freight elevators of the Building,
shall be at the risk of Tenant only, and that Landlord shall not be liable for any loss or damage thereto or theft thereof. Without limiting any other provisions hereof, but subject to the provisions of Section 10(a) hereof, except for
liability caused by the gross negligence or willful acts of Landlord or its agents, employees or contractors, Tenant agrees to defend, protect, indemnify and save harmless Landlord and its partners, affiliates, officers, agents, servants and
employees from and against all liability to third parties arising out of the use of the Premises or the acts or omissions of Tenant or its servants, agents, employees, contractors, suppliers or workers.

Except for liability caused by the negligence or willful acts or omissions of Tenant or Tenants partners, affiliates, officers,
agents, servants or employees and subject to Section 10(a) hereof, Landlord agrees to defend, protect, indemnify and save harmless Tenant and its partners, shareholders, directors, affiliates, officers, agents, servants, contractors and
employees from and against all liability to third parties arising out of negligent acts or omissions of Landlord or its servants, agents, employees, contractors, suppliers or workers.

The provisions of this Section 12 shall survive the expiration of the Term or earlier termination of this Lease or the
termination of Tenants right to possession of the Premises.



|13. | NONWAIVER
|--- | ---------

No
waiver of any provision of this Lease shall be implied by any failure of either Landlord or Tenant to enforce any remedy on account of the violation of such provisions, even if such violation is continued or repeated subsequently, and no express
waiver shall affect any provision other than the one specified in such waiver and that one only for the

time and in the manner specifically stated. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Term or of Tenants
right of possession hereunder or after the giving of any notice shall reinstate, continue or extend the Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement
of a suit or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.



|14. | CONDEMNATION
|--- | ------------

If
the Land or the Building (or a material portion of the Land or Building) shall be taken or condemned by any competent authority for any public or quasi-public use or purpose, Landlord shall have the right, exercisable at its sole discretion, to
cancel this Lease upon not less than sixty (60) days notice prior to the date of cancellation designated in the notice. No money or other consideration shall be payable by Landlord to Tenant for the right of cancellation and Tenant shall have
no right to share in the condemnation award or in any judgment for damages caused by such taking or condemnation. Notwithstanding the foregoing, Tenant may pursue a separate award to recover the cost of Tenants moving expenses and improvements
to the Premises paid for by Tenant and the loss of any trade fixtures or personal property, provided that such separate award shall not reduce the award or judgment recoverable by Landlord.



|15. | ASSIGNMENT AND SUBLETTING
|--- | -------------------------



| | (a) | Subject to any provisions of this Section 15 to the contrary, Tenant shall not, without the prior written consent of Landlord, which
consent shall not be unreasonably withheld or delayed, (i) assign, convey or mortgage this Lease or any interest hereunder; (ii) permit to occur or permit to exist any assignment of this Lease, or any lien upon Tenants interest,
voluntarily or by operation of law; (iii) sublet the Premises or any part thereof; (iv) advertise as available for sublet or assignment all or any portion of the Premises; or (v) permit the use of the Premises by any parties other
than Tenant and its employees. Any such action on the part of Tenant shall be void and of no effect. There shall be no partial assignment of Tenants interest in this Lease. Notwithstanding anything contained herein to the contrary, Landlord
shall not be deemed to have acted unreasonably in its election not to consent to any such action on the part of Tenant because (aa) a Default shall have occurred and be continuing under this Lease or Tenant shall otherwise be in default in the
performance of the terms, covenants or conditions contained in this Lease, (bb) the proposed assignee or sublessee (the Proposed Tenant)shall be an existing tenant or occupant of the Building, (cc) such assignment or subletting
shall cause Landlord to be in breach of any exclusive use or similar provision contained in any other lease for space in the Building (provided that such provision shall not be in conflict with the use provision set forth in the
Schedule), (dd) in the reasonable judgment of Landlord, the Proposed Tenant is of a character or is engaged in a business which would be deleterious to the reputation of the Building, or the Proposed Tenant is not

| | sufficiently financially responsible to perform its obligations under any such assignment or sublease, or the Proposed Tenant or any of its partners, members, shareholders, employees or
affiliates, or the business conducted by any of them, could pose a security risk for the Building and/or its occupants, (ee) the portion of the Premises which Tenant proposes to sublease including the means of ingress and egress thereto and the
proposed use thereof, and the remaining portion of the Premises will violate any city, state or federal law, ordinance or regulation, (ff) the Proposed Tenant is a government agency (or any subdivision thereof), (gg) the Proposed Tenant is a party
with whom Landlord is then actively negotiating a lease for space in the Building, (hh) the portion of the Premises which Tenant proposes to assign or sublease does not consist of contiguous space, provided, however, that the foregoing are merely
examples of the reasons for which Landlord may reasonably not consent to any such actions by Tenant and shall not be deemed exclusive of any reason for reasonably making such election, whether similar or dissimilar to the foregoing examples.
The term sublease and all words derived therefrom, as used in this Section 15 shall include any subsequent sublease or assignment of such sublease and any other interest arising under such sublease. Landlords
consent to any assignment, subletting or transfer or Landlords election to accept any assignee, subtenant or transferee as the Tenant hereunder and to collect rent from such assignee, subtenant or transferee shall not release Tenant or any
subsequent Tenant from any covenant or obligation under this Lease, and Tenant further expressly acknowledges and agrees that any renewal rights, expansion rights, reduction rights, rights of first offer, termination rights or limitations on Taxes
or Operating Expenses shall be deemed personal to the original Tenant and shall not inure to the benefit of any assignee, subtenant or transferee taking from the original Tenant. Landlords consent to any assignment, subletting or transfer
shall not constitute a waiver of Landlords right to withhold its consent to any future assignment, subletting, or transfer. Landlord may condition its consent upon execution by the subtenant or assignee of an instrument confirming such
restrictions on further subleasing or assignment and joining in the waivers and indemnities made by Tenant hereunder insofar as such waivers and indemnities relate to the affected space. Without limiting the foregoing, Tenant agrees to indemnify,
defend and hold Landlord and its employees, agents, their officers and partners harmless from and against any claims made by any broker or finder for a commission or fee in connection with any subleasing or assignment by Tenant or any subtenant or
assignee of Tenant.

| | (b) | If Tenant desires the consent of Landlord to an assignment or subletting or in the event Tenant desires to assign or sublet the Premises to Permitted Assignees
(as hereinafter defined) where Landlords consent is not required pursuant to Section 15(f) below, Tenant shall submit to Landlord, at least twenty (20) days prior to the proposed effective date of the assignment or sublease, a
written notice which includes:

| | (i) | All documentation then available related to the proposed sublease or assignment; and

---

| | (ii) | Sufficient information to permit Landlord to determine the identity and character of the proposed subtenant or assignee and the financial condition of the proposed
assignee or subtenant.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Landlord agrees to notify Tenant as to whether Landlord consents to such
assignment or sublease within twenty (20) days after receipt by Landlord of all documents required pursuant to (i) and (ii) above; provided, however, that copies of the final executed documentation must be supplied to Landlord by
Tenant at least ten (10) business days prior to the effective date of such assignment or sublease and Landlord shall have an additional ten (10) business days after receipt of such revised documents, or the remainder of the original twenty
(20) day period, whichever is longer, to either approve or disapprove of such assignment or sublease. If the terms of the proposed sublease or assignment change in any material respect from the terms contained in the documents previously
delivered to Landlord pursuant to this subparagraph, or the identity of the sublessee or assignee changes, then Tenant shall resubmit the documentation to Landlord indicating the changes and Landlord shall have an additional twenty (20) days to
either approve or disapprove of such assignment or sublease.



| | (c) | In addition to withholding its consent Landlord shall have the right to terminate this Lease in the event of a proposed assignment of this Lease or a proposed sublease
of the entire Premises or to terminate this Lease as to that portion of the Premises which Tenant seeks to sublet, if Tenant seeks to sublease less than the entire Premises. Landlord may exercise such right to terminate by giving written notice to
Tenant at any time on or before the date by which Landlord is required to consent or object to such assignment or sublease. If Landlord exercises its right to terminate, the Lease or portion thereof shall be deemed terminated effective as of,
Landlord shall be entitled to recover possession of and Tenant shall surrender such portion of the Premises on the earlier of: (i) the proposed date for possession by such assignee or subtenant, or (ii) ninety (90) days after the date
of Landlords notice of termination to Tenant. Notwithstanding the foregoing, Tenant shall have the right to rescind its request to assign the Lease or sublet the Premises within five (5) days after receipt of Landlords notice of
recapture and upon receipt of said rescission notice, the Lease shall remain in full force and effect. Time is of the essence of this provision.

| | (d) | If Landlord consents to any assignment of this Lease or a sublease of the Premises, as a condition of Landlords consent, Tenant shall pay
to Landlord any reasonable attorneys fees not to exceed $2,500 and expenses incurred by Landlord in connection with such assignment or sublease plus fifty percent (50%) of all Sublease Profits (as defined below) derived by Tenant from
such assignment or sublease. Sublease Profitsshall mean the entire excess (after deducting all reasonable costs of subletting) of revenues generated by the assignment of this Lease or the subleasing of the Premises over the Rent
applicable thereto. All such revenues shall be applied first to reimbursement of such costs of subletting or assigning until they are paid in full. Tenant shall furnish Landlord with a sworn statement, certified by an officer of Tenant, setting

thereof. If a part of the consideration for such assignment shall be payable other than in cash, the payment to Landlord shall be payable in accordance with the foregoing percentage of the cash and other non-cash considerations in such form as is
reasonably satisfactory to Landlord. Such percentage of Sublease Profits shall be paid to Landlord promptly by Tenant upon Tenants receipt from time to time of periodic payments from such assignee or subtenant or at such other time as Tenant
shall realize Sublease Profits from such assignment or sublease. If such sublease or assignment is part of a larger transaction in which other assets of Tenant are being transferred, the consideration for the assignment or sublease shall be a
reasonable allocation of the total value received minus a reasonable allocation of the total expenses incurred in connection with such transaction.

| | (e) | If Tenant is a partnership, a withdrawal or change, whether voluntary, involuntary or by operation of law or in one or more transactions, of partners owning
directly or indirectly a controlling interest in Tenant shall be deemed an assignment of this Lease and subject to the provisions of this Section 15. If Tenant is a corporation, any dissolution, merger, consolidation or other
reorganization of Tenant, or the sale, transfer or redemption of a direct or indirect controlling interest in the capital stock of Tenant, in one or more transactions, shall be deemed a voluntary assignment of this Lease and subject to the
provisions of this Section 15. Neither this Lease nor any interest therein nor any estate created thereby shall pass by operation of law or otherwise to any trustee, custodian or receiver in bankruptcy of Tenant or any assignee for the
assignment of the benefit of creditors of Tenant.

| | (f) | Notwithstanding anything contained in this Section 15 to the contrary, Tenant shall have the right, upon prior written notice to
Landlord but without Landlords consent, to assign or sublet all of the Premises to Permitted Assignees (as hereinafter defined), provided that such assignment or subletting shall not relieve Tenant of its primary responsibility for the
performance of all obligations of Tenant hereunder, and in the event of an assignment to a Permitted Assignee, such Permitted Assignee assumes, pursuant to an agreement in form and substance reasonably satisfactory to Landlord, the obligations of
Tenant hereunder and in the event of a sublet, such sublet is governed by a form of sublease reasonably approved in advance by Landlord. As used herein, a Permitted Assignee shall mean (i) any entity owned or controlled by

Tenant agrees to deliver to Landlord, within ten (10) business days prior to the effective date of such assignment or sublease, fully executed copies of the documents effectuating such assignment or sublease. Upon written request, Landlord
agrees that any financial information delivered to Landlord regarding the Permitted Assignee, which is not a public company, shall be deemed to be confidential, provided, however, Landlords members, managers, managing agents, accountants,

|16. | SURRENDER OF POSSESSION
|--- | -----------------------

Upon the expiration of the Term or upon the termination of Tenants right of possession, whether by lapse of time or at the option of Landlord as herein provided, Tenant shall forthwith surrender the
Premises to Landlord in good order, repair and condition, ordinary wear and damage resulting from fire or other casualty excepted. Any interest of Tenant in the alterations, improvements, installations and additions to the Premises made or paid for
by Landlord or Tenant shall, without compensation to Tenant, become Landlords property at the termination of this Lease by lapse of time or otherwise and such alterations, improvements, installations and additions shall be relinquished to
Landlord in good condition, ordinary wear excepted. Prior to the termination of the Term or of Tenants right of possession Tenant shall remove its office furniture, trade fixtures, office equipment and all other items of Tenants movable
property on the Premises. Unless requested to do so by Landlord, Tenant shall not have any right to remove, any alterations, improvements, installations or additions, which shall include built-in furniture or shelves and all other attached items,
excluding trade fixtures. Tenant shall pay to Landlord upon demand the cost of repairing any damage to the Premises and to the Building caused by any such removal. If Tenant fails or refuses to remove any such property from the Premises, Tenant
shall be conclusively presumed to have abandoned the same, and title thereto shall thereupon pass to Landlord without any cost either by set-off, credit, allowance or otherwise, and at its option Landlord may: (i) accept the title to the
property; (ii) or at Tenants expense remove the property or any part in any manner that Landlord shall choose, repairing any damage to the Premises caused by such removal; and store, destroy or otherwise dispose of the property without
incurring liability to Tenant or any other person. Landlord expressly acknowledges and agrees that nothing contained in this Lease to the contrary shall require Tenant to remove any improvements or additions installed by or on behalf of Tenant
pursuant to the Tenant Work Letter or any alterations performed by Tenant pursuant to Section 8 above (unless at the time Landlord shall approve the installation of such alterations, Landlord shall have notified Tenant in writing that
such removal would be required at the expiration of the Term) or otherwise require Tenant to bring the Premises back to raw space. During Tenants move from the Premises, Tenants agents, contractors, mechanics and movers shall
work in harmony and not interfere with Landlords or another tenants agents, contractors and mechanics. If at any time Tenants agents, contractors, mechanics or movers shall in the judgment of Landlord cause or threaten to cause
disharmony or



27

interference, Landlord shall have the right to request that such agents, contractors, mechanics or movers immediately leave the Premises and Building.



|17. | HOLDING OVER
|--- | ------------

During each month or portion thereof for which Tenant shall retain possession of the Premises or any portion thereof after the expiration or termination of the Term or of Tenants right of
possession, whether by lapse of time or otherwise, Tenant shall pay to Landlord an amount as Rent equal to (i) 150% of one-twelfth of the Base Rent and 150% of one-twelfth of the Additional Rent paid by Tenant during the previous Lease Year for
all of the Premises (regardless of whether Tenant retains possession of all or only a portion of the Premises) for the first thirty (30) days Tenant so retains possession of the Premises (regardless of whether Tenant retains possession of the
Premises or a portion thereof for all or only a portion of such month) and (ii) commencing on the 31stday of the holdover, 200% of one-twelfth of the Base Rent and 200% of one-twelfth of the Additional Rent paid by Tenant during the previous Lease Year for all of the Premises (regardless of whether
Tenant retains possession of all or only a portion of the Premises). Tenant shall also pay all damages sustained by Landlord on account of such holding over. The provisions of this Section 17 shall not be deemed to limit or constitute a
waiver of any other rights or remedies of Landlord provided herein or at law.



|18. | ESTOPPEL CERTIFICATE
|--- | --------------------

Tenant agrees, that, from time to time upon not less than ten (10) business days prior request by Landlord, Tenant, or Tenants duly authorized representative having actual knowledge of
the following facts, will deliver to Landlord a statement in writing certifying: (i) that this Lease is unmodified and in full force and effect (or if there have been modifications, a description of such modifications and that the Lease as
modified is in full force and effect); (ii) the dates to which Rent and other charges have been paid; (iii) that, to Tenants knowledge, the Landlord is not in default under any provision of this Lease, or, if in default, the nature
thereof in detail; and (iv) such further matters as are set forth on the form of estoppel certificate attached hereto as Exhibit D and made a part hereof, or as may be reasonably requested by Landlord, it being intended that any such
statement may be relied upon by any mortgagees or prospective mortgagees, or any prospective assignee of any Mortgagee, or any prospective and/or subsequent purchaser or transferee of all or a part of Landlords interest in the Land and/or
Building. Tenant shall execute and deliver whatever instruments may be required for such purposes within ten (10) business days following Landlords request therefore.



|19. | OBLIGATIONS TO MORTGAGEES
|--- | -------------------------



| | (a) | Subordination.This Lease is subject and subordinate to the lien of any mortgages or trust deeds now and hereafter in force against the
Land or Building and to all renewals, extensions, modifications, consolidation and replacements thereof. At Landlords request (and after consent from any prior mortgagee or lessor if Tenant has agreed not to so subordinate without such
consent), Tenant shall execute such further instruments or assurances as Landlord may deem necessary to evidence, confirm or effectuate such subordination of this Lease

| | thereto or, if requested, to make Tenants interest in this Lease superior thereto. If any mortgage shall be foreclosed or property encumbered thereby is transferred in lieu of foreclosure,
or if any such future ground or improvements lease or underlying lease is terminated: (i) the liability of the mortgagee, trustee, transferee, purchaser at such foreclosure sale or ground lessor or improvements lessor and the liability of a
subsequent owner (all of the foregoing parties are collectively referred to as Mortgagee)shall exist only with respect to the period during which the Mortgagee is the owner of the Land or Building and the Mortgagee shall be
released from any further liability upon its transfer of ownership; and (ii) the Mortgagee shall not have any liability whatsoever for the acts of the Landlord prior to any such transfer nor any liability for any deposits made by Tenant
hereunder unless Mortgagee has received such deposits; and (iii) Tenant hereby agrees to attorn to and recognize as Landlord, Mortgagee and, upon request of the Mortgagee, will execute such instruments as may be required by said Mortgagee.
Landlord represents and warrants to Tenant that, as of the date of this Lease, Landlord is not in default under the terms and conditions of any mortgage, deed of trust or ground lease affecting the Property and, to Landlords actual knowledge,
no event has occurred which would constitute a default under any mortgage, deed of trust or ground lease affecting the Property, either upon service of notice or passage of time.

| | (b) | Notice to Landlord and Mortgagee.If any act or omission by Landlord would give Tenant the right to damages from Landlord or any rights with respect to
this Lease, Tenant will not sue for such damages or exercise any such rights until (i) it shall have given written notice of the act or omission to Landlord and to the holder(s) of the indebtedness or other obligations secured by any mortgage
or deed of trust affecting the Premises or of any ground or underlying lease, if the name and address of such holder(s) have been furnished to Tenant; and (ii) a reasonable period of time (in light both of the time required to cure the act or
omission and the effect of the act or omission on Tenants business operations in the Premises) to cure the act or omission has elapsed following the giving of the notice, during which time Landlord and such holder(s), or either of them, their
agents or employees, will be entitled to enter upon the Premises and do therein whatever may be necessary to cure the act or omission.

|20. | CERTAIN RIGHTS RESERVED BY LANDLORD
|--- | -----------------------------------

Landlord shall have the following rights, each of which Landlord may exercise without notice to Tenant (but subject to maintaining access to the Premises as described in subparagraph (iii) below),
and without liability to Tenant for damage or injury to property, person or business on account of the exercise thereof, and the exercise of any such rights shall not be deemed to constitute an eviction or disturbance of Tenants use or
possession of the Premises and shall not give rise to any claim for set-off or abatement of rent or any other claim:



| | (i) | To change the name or street address of the Building.
| | --- | -----------------------------------------------------

combination of any safes, cabinets or vaults left in the Premises.

Movements of Tenants property into or out of the Building or Premises and within the Building are entirely at the risk and responsibility of Tenant, and Landlord reserves the right to require permits before allowing any property to be moved
into or out of the Building or Premises.

|22. | DEFAULT AND LANDLORDS REMEDIES
|--- | -------------------------------



| | (a) | Default.Any one or more of the following events shall be a default (Default)under this Lease: (i) If Tenant
does not pay the Rent or any installment thereof or does not pay any other sum required to be paid by Tenant under this Lease or under the terms of any other agreement between Landlord (or Landlords predecessors in title) and Tenant and such
default shall continue for five (5) days after written notice to Tenant; or (ii) if Tenant fails to observe or perform any of the other covenants or conditions in this Lease which Tenant is required to observe and perform and such default
shall continue for twenty (20) days after written notice to Tenant, provided, however, if such default does not involve a hazardous condition and is susceptible to cure but cannot, by the use of reasonable efforts, be cured within twenty
(20) days, Landlord shall not exercise any of its remedies hereunder if and so long as (a) Tenant shall have commenced to cure such default within twenty (20) days and (b) Tenant shall thereafter continuously

| | and diligently proceed to cure such default in a manner reasonably satisfactory to Landlord, and (c) such default shall be cured within sixty (60) days of such notice to Tenant; or
(iii) if a default is made in the performance by Tenant of any covenant of this Lease which involves a hazardous condition and is not cured by Tenant immediately upon written notice to Tenant; or (iv) if the interest of Tenant in this
Lease shall be levied on under execution or other legal process; or (v) if any voluntary petition in bankruptcy or for corporate reorganization or any similar relief shall be filed by Tenant; or (vi) if any involuntary petition in
bankruptcy shall be filed against Tenant under any federal or state bankruptcy or insolvency act and shall not have been dismissed within ninety (90) days from the filing thereof; or (vii) if a receiver shall be appointed for Tenant or any
of the property of Tenant by any court and such receiver shall not have been dismissed within ninety (90) days from the date of his appointment; or (viii) if Tenant shall make an assignment for the benefit of creditors; or (ix) if
Tenant shall admit in writing Tenants inability to meet Tenants debts as they mature; or (x) if Tenant fails to replenish the Security Deposit as provided in Section 29 hereof.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Landlords Remedies.If a Default occurs, Landlord may, at its sole option, with or without further notice or demand of any kind to Tenant or any
other person, have any one or more of the following described remedies in addition to all other rights and remedies provided at law or in equity or elsewhere herein (provided that Landlord shall use such efforts as are required by law to mitigate
any damages resulting from such Default):
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | Terminate this Lease and the Term created hereby and immediately, repossess the Premises. If Landlord does terminate this Lease and repossess
the Premises, Landlord shall be entitled to immediately recover, in addition to any other sums or damages for which Tenant may be liable to Landlord, as damages a sum of money equal to the greater of: (1) the excess of the present value of the
Rent provided to be paid by Tenant for the balance of the Term (disregarding any unexpired period of initial Rent abatement) over the present value of the anticipated fair market rent for the Premises (computed based upon the yield on U.S. Treasury
obligations having a maturity closest to the Termination Date) that could be achieved for said period, after deduction of all anticipated expenses of reletting, including, without limitation, all allowances, abatements, construction costs, brokerage
commissions and tenant concessions likely to be required under then-existing market conditions; or (2) the unamortized portion of any rent abatements, allowances, construction costs, brokerage commissions and other costs incurred by Landlord in
connection with this Lease, as amortized on a straight-line basis with interest on the unamortized amount at twelve percent (12%) per annum over the initial Term during which Base Rent is payable. Should the present value of the anticipated
fair market rent for the Premises, after deduction of all anticipated expenses of reletting, that could be achieved for the balance of the Term exceed the present value of the Rent provided to be paid by Tenant for the balance of the Term, Landlord
shall have no

| | obligation to pay to Tenant the excess or any part thereof or to credit such excess or any part thereof against any other sums or damages for which Tenant may be liable to Landlord.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Landlord may terminate Tenants right of possession and may repossess the Premises by forcible entry and detainer suit, by taking peaceful possession or
otherwise, without terminating this Lease. If Landlord terminates Tenants right of possession without terminating this Lease, Landlord shall take reasonable measures to the extent required by law, to relet the same for the account of Tenant,
for such rent and upon such terms as shall be reasonably satisfactory to Landlord. Reasonable measures shall not obligate Landlord to show the Premises before showing other space in the Building to a prospective tenant. For the purpose of such
reletting, Landlord is authorized to decorate, repair, remodel or alter the Premises and to relet the Premises at such rental rate (which may be higher than the rental rate then applicable under this Lease), as Landlord reasonably determines to be
necessary to maximize the effective rent on reletting. If Landlord shall fail to relet the Premises, Tenant shall pay to Landlord as damages the amount of the Rent reserved in this Lease for the balance of the Term as due hereunder. If the Premises
are relet and a sufficient sum shall not be realized from such reletting after paying all of the costs and expenses of all decoration, repairs, remodeling, alterations, installations and additions and the expenses of such reletting (including all
allowances, abatements and other tenant concessions required under then-existing market conditions), to satisfy the Rent provided for in this Lease, Tenant shall satisfy and pay the same upon demand therefore from time to time. Tenant shall not be
entitled to any rents received by Landlord in excess of the Rent provided for in this Lease. Tenant agrees that Landlord may file suit to recover any sums falling due under the terms of this Section 22 from time to time and that no suit
or recovery of any portion due Landlord hereunder shall be any defense to any subsequent action brought for any amount not theretofore reduced to judgment in favor of Landlord.

| | (c) | Jury Trial Waiver.Tenant hereby waives its rights to a trial by jury in any action or proceeding based upon or related to the subject matter of this
Lease and the business relationship that is being established. This waiver is knowingly, intentionally and voluntarily made by Tenant and Tenant acknowledges neither Landlord nor any person acting on behalf of Landlord has made any representations
of fact to include this waiver of trial by jury or has taken any actions which in any way modify or nullify its effect. Tenant acknowledges that this waiver is a material inducement to enter into this Lease and that Landlord has already relied on
this waiver in entering into this Lease and that Landlord will continue to rely on this waiver in its future dealings with Tenant. Tenant further acknowledges that it has been represented (or has had the opportunity to be represented) in the signing
of this Lease and in the making of this waiver by independent legal counsel.

|--- | ---------------------------

Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions
and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof.



|25. | REAL ESTATE BROKER
|--- | ------------------

Each party represents that it has dealt with (and only with) the Broker(s) specified in Item 9 of the Schedule as
broker in connection with this Lease, and that insofar as such party knows, no other brokers negotiated this Lease or are entitled to any commissions in connection therewith. Each party agrees to indemnify, defend and hold the other and its
employees, agents, their officers and partners, harmless from and against any claims resulting from a breach of the foregoing representation.

| | (i) | Transfer of Landlords Interest.Tenant agrees that Landlord has the right to transfer its interest in the Land and Building and in this Lease,
including the security deposit delivered by Tenant to Landlord hereunder. If such a transfer occurs, and the security deposit is assigned to the transferee, Landlord shall automatically be released from all liability under this Lease arising after
the date of such transfer and Tenant agrees to look solely to such transferee for the performance of Landlords obligations hereunder arising after the date of such transfer. Tenant further acknowledges that the Landlord may assign its interest
in this Lease to a mortgage lender as additional security and agrees that such an assignment shall not release Landlord from its obligations hereunder and that Tenant shall continue to look to Landlord for the performance of its obligations
hereunder.

administrative proceeding or order. Nothing contained herein shall, however, prevent Tenant from exercising its rights or remedies under law or this Lease on account of any breach or default by Landlord as against Landlords interests in the
Land and Building (or either of them), the other assets of Landlord or to terminate this Lease.

Deposit, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by law (it being intended that Landlord shall not first be required to proceed against the Security Deposit)

Credit expiring not earlier than one (1) year from the expiration of the prior Letter of Credit and meeting all of the other requirements set forth herein or an amendment to the existing Letter of Credit extending the maturity date thereof for

Rent).Upon receipt by Tenant of such proposal from Landlord, Tenant may accept or reject the proposal within seven (7) business days after receipt thereof. In the event Tenant rejects the proposal, Landlord and Tenant shall negotiate

| | (c) | Time is of the essence with respect to the provisions of this Section 31. Tenants Renewal Option shall expire and become null and void if it is
not exercised by Tenant in a timely manner. In the event Tenant does not reject Landlords proposal of Market Rent as set forth in Section 31 (a) above, Tenant shall be deemed to have accepted Landlords calculation of
Market Rent.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Tenants exercise of its Renewal Option shall become null and void if Tenant is in Default (after expiration of applicable notice and cure periods) under
this Lease at the time of the commencement of the Extended Term.

they meet with Landlords approval. Tenant shall cause the Construction Documents to be revised until they will meet with Landlords approval. The Architectural Design Plans, the MEP/CT Engineering Plans and the Construction Documents are
herein collectively referred to as the Plans.

| | (h) | Tenant represents to Landlord that Tenant has reviewed its needs with the Interior Space Planner and that Tenant has assured itself that the Plans can be delivered as
herein above required. Tenant agrees to cooperate with the Interior Space Planner as promptly as possible and in any event in sufficient time to cause the Plans to be prepared and timely delivered as herein above required.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | Neither review nor approval by Landlord of any of the Plans shall constitute a representation or warranty by Landlord that such Plans either (i) are complete or
suitable for their intended purpose or (ii) comply with applicable laws, ordinances, codes and regulations, it being expressly agreed by Tenant that Landlord assumes no responsibility or liability whatsoever to Tenant or to any other person or
entity for such completeness, suitability or compliance.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (j) | Tenants obligation to pay Rent under the Lease shall not be affected or deferred on account of any such delay to the extent the same results from any of the
following events (collectively, Tenant Delays).
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(i) The failure of Tenant to furnish
any of the Plans in accordance with the schedule and meeting the requirements set forth in this Section 1 including, without limitation, the failure of Landlord and Tenant to agree upon final versions of the Plans, or

(ii) Changes in the Plans requested by Tenant (notwithstanding Landlords approval of such changes); or

(iii) The performance of any work by Tenant or any person, firm or corporation employed by Tenant; or

Landlords determination as to the duration of Tenant Delays shall be conclusive and binding upon Tenant absent manifest
error.



|3. | Cost of Tenants Work
|-- | ---------------------



| | (a) | Prior to commencement of any portion of the Tenants Work, Tenant shall obtain a contract to perform the Tenants Work by bidding the Tenants Work to
certain of those general contractors from Landlords list of approved contractors which list is attached hereto as Schedule B-2and made a part hereof or as otherwise approved by Landlord in writing. Tenant agrees to promptly give
Landlord a copy of the contract. The general contractor must use only those subcontractors on Landlords list of approved subcontractors set forth on Schedule B-2attached hereto, as the same may be amended by Landlord from time
to time.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Intentionally Omitted.
| | --- | ----------------------



| | (c) | Landlord shall give Tenant a total allowance (Allowance)of Fifty-Five Thousand Six Hundred Seventy-Five and no/100 Dollars ($55,675.00) as a credit
toward the hard costs, architectural/design fees, engineering and mechanical design fees and voice/data cabling and Landlords Expenses. Tenant shall pay the amount by which the aggregate cost of the Tenants Work, the preparation of the
Plans, Landlords Expenses and any other costs incurred by Tenant in connection with the preparation of the Premises exceeds the Allowance (the Excess Costs). Tenant shall deposit the amount of the Excess Costs, if any, with
Landlord within five (5) business days following the determination of the construction price as provided in Paragraph 3(a) above.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Tenant shall pay for the cost of temporary electricity, temporary toilets, access to phone service and hot and cold water to the Premises during the construction
period; (iv) all hoisting charges for reserving and using the Buildings freight elevators during normal Building hours for the construction of the Work which use is related to the Tenants Work and any punchlist items; (v) the
costs of trash removal and disposal (as described in Section 5(d) hereof); and (vi) freight dock services and normal Building security during Tenants construction and move-in period (Landlords
Expenses).Landlord agrees that Tenant shall not be required to pay a coordination fee for coordination services by Landlord.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Prior to commencing Tenants Work, Tenant shall submit to Landlord a total project budget (the Budget)outlining the
cost of the Tenants Work plus the cost of all non-tenant improvement items, including soft costs, cabling, and telephone to be incurred by Tenant in connection with the Premises (collectively, the Tenants Project
Costs).Tenant shall deliver to Landlord an updated Budget with each draw request for a payment of a portion of the Deposit. If, as of the time any such draw request is made, the Tenants Project Costs pursuant to the
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



B-4



---

| | current Budget exceed the amount of the Deposit, Tenant shall deposit into the escrow the amount by which the Tenants Project Costs set forth in the current Budget exceed the amount of the
Deposit multiplied by a fraction, the numerator of which is the Tenants Project Costs incurred to date after the payment of the amount requested in the current draw and the denominator of which is the estimated total cost of the Tenants
Project Costs as described in the current Budget the product of which shall be reduced by any amounts previously deposited into the escrow by Tenant. For example, if at the time that Tenant makes its second draw on the escrow, the Budget has
increased to $70.00 per square foot of Rentable Area in the Premises from the initial Budget of $65.00 per square foot and if after the payment of the amount requested in the second draw request $35.00 per square foot of Rentable Area will have been
paid out of the escrow, then at the time the second draw request is made, Tenant shall deposit into the escrow $5.00 per square foot of Rentable Area in the Premises multiplied by 1/2(i.e., $35.00 divided by $70.00) less any amounts previously
deposited into the escrow by Tenant. All amounts so deposited by Tenant are herein collectively called Tenant Deposits.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | Tenant shall make draw requests on the escrow based upon the percentage of Tenants Project Costs incurred as of the date of the draw request. Tenant shall present
to Landlord, or to the title company, which is acting as escrowee, a letter requesting a disbursement of funds, invoices (or paid receipts for each item paid by Tenant and for which Tenant is seeking reimbursement), a copy of any cancelled checks
pursuant to which such invoice has been paid, and, with respect to any construction to any portion of the Premises, such lien waivers (for lienable items) required by the title company or Landlord. The lien waiver from the general contractor and
from each subcontractor and material supplier must be delivered with each draw request. Landlord shall have no obligation to make a payment until all waivers for the draw in question are submitted. If Landlord acts as escrowee and if there is a
single disbursement request, Landlord will not impose an administrative charge. If Tenant has multiple requests, Landlord reserves the right to impose a reasonable administrative charge.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | Draw requests shall be submitted to Landlord and the title company not later than the 23rdday of the calendar month. Not later than the 20thday of the next calendar month Landlord will review Tenants Work and Tenants draw request and advise
Tenant in writing of any respects in which the draw request is disapproved and the reason for such disapproval. Such advice need not comply with the notice provisions of the Lease. Otherwise, the draw request will be deemed approved. Draw requests
submitted by the 23rdday of a calendar month shall be
paid, subject to the foregoing approval procedure, not later than the 25thday of the following calendar month. Landlord and Tenant agree to cooperate in attempting to resolve disapproved portions of each draw request.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (h) | In the event the Allowance exceeds the actual costs to pay for Tenants Work, Landlord Expenses and the other costs payable by Tenant hereunder,
any unused portion of the Allowance (Available Allowance)may be applied by Tenant
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



B-5



---

| | toward a rent credit which shall be amortized over the Lease Term. By way of illustration, if $10.00 per rentable square foot is the Available Allowance, it will be amortized over the 5 year term
and will be equal to $2.00 per rentable square foot per annum, which will be deducted from the annual Base Rent rental rate set forth in Schedule 1. Tenant shall have 180 days to commence Tenants Work, and if Tenant elects not to perform any
of Tenants Work, Tenant may apply the entire Allowance as a rent credit amortized over the remainder of the Term.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Access by Tenant: Work in Harmony.
|-- | ----------------------------------

Landlord shall permit Tenant and Tenants agents, representatives, employees, suppliers, contractors, subcontractors, mechanics, and workmen to enter
the Premises prior to the Commencement Date. Tenant agrees for itself and its agents, representatives, employees, suppliers, contractors, subcontractors, workmen, mechanics, and suppliers, that all such parties shall work in harmony and not
unreasonably interfere with Landlord and Landlords agents, representatives, employees, suppliers, contractors, subcontractors, mechanics, and workmen in doing work for other tenants and occupants of the Building.



|5. | Construction Requirements.
|-- | --------------------------



| | (a) | Tenant agrees that the entry into the Premises by Tenant and its contractors shall be deemed to be under all of the terms, covenants, conditions and provisions of the
Lease except as to the covenant to pay Rent, and Tenant further agrees that in connection therewith Landlord shall not be liable in any way for any injury, loss, or damage which may occur to any of Tenants Work and installations made in the
Premises or to property placed therein prior to the Commencement Date and thereafter, the same being at Tenants sole risk. In addition, Tenant shall require all entities performing work on behalf of Tenant to provide protection for existing
improvements to an extent that is satisfactory to Landlord and shall allow Landlord access to the Premises, for inspection purposes, at all times during the period when Tenant is undertaking construction activities therein. If any entity performing
work on behalf of Tenant causes any injury to any person or any damage to the Premises, the Building (including the Landlords Work), any other property of Landlord or any other person, then Tenant agrees to indemnify, defend and hold Landlord
harmless from any loss, damage or injury suffered in connection with any such damage or injury. Further, Tenant shall cause such damage to be repaired at Tenants expense and if Tenant fails to cause such damage to be repaired promptly upon
Landlords demand therefore, Landlord may in addition to any other rights or remedies available to Landlord under this Lease or at law or equity cause such damage to be repaired, in which event Tenant shall promptly upon Landlords demand
pay to Landlord the cost of such repairs;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | All contractors and subcontractors shall use only those service corridors and service entrances designated by Landlord for ingress and egress of
personnel and the delivery and removal of equipment and material through or across any common areas of the Building shall only be permitted with the written approval of Landlord and during hours determined by Landlord. Landlord shall have the right
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



B-6



---

| | to order Tenant or any contractor or subcontractor who violates the above requirements to cease work in the Building and leave the Building and remove its equipment and its employees from the
Building and, at Landlords option restore any portion of the Building on which it has done work to its original condition;
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Landlord shall allow Tenant and Tenants contractors to have use of the hoist serving the Building during normal operating hours. To the extent Tenant or
Tenants contractors require use of the hoist after normal operating hours Landlord shall use reasonable efforts to accommodate Tenant and the cost thereof shall be determined at Landlords reasonable discretion. Landlord shall not be
required to defer use of the hoist by Landlord or others until after normal operating hours in order to allow use of the hoist by Tenant or Tenants contractors during normal operating hours. Scheduling of Tenants work in the Premises and
the use of said hoist shall be at the reasonable discretion of Landlord or Landlords contractor;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | During the performance of Tenants Work and Tenants fixturing, Landlord may provide trash removal service from a location designated by Landlord. Tenant
shall be responsible for breaking down boxes and placing trash in Landlords containers at such designated location. Tenant shall accumulate its trash in containers supplied by Landlord and Tenant shall not permit trash to accumulate within the
Premises or in the corridors or public areas adjacent to the Premises. Tenant shall cause each entity employed by it to perform work on the Premises to abide by the provisions of this Work Letter as to the storage of trash and shall require each
such entity to perform its work in a way that dust or dirt is contained entirely within the Premises and not within any other portion of the Building and shall cause Tenants contractors to leave the Premises in broom clean condition at the end
of each day. Should Landlord deem it necessary to remove Tenants trash because of accumulation, Tenant shall pay to Landlord an additional reasonable charge for such removal on a time and material basis. The cost to Tenant for Landlord
removing such trash will be based on reasonable and competitive cost which Tenant could have secured independently had Landlord not provided such service;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Tenant agrees that all services and work performed on the Premises by, on behalf of, or for the account of Tenant, including installation of telephones, carpeting,
materials and personal property delivered to the Premises shall be done in a first-class workmanlike manner using only good grades of material and shall be performed only by persons covered by a collective bargaining agreement with the appropriate
trade union;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | Tenant agrees to protect, indemnify, defend and hold Landlord and its agents, partners, contractors and employees harmless from and against any and all
losses, damages, liabilities, claims, liens, costs, and expenses, including reasonable attorneys fees, of whatever nature including those to the person and property of Tenant, its employees, agents, invitees, licensees and others arising out
of or in connection with the activities of Tenant or Tenants contractors in or about the

| | (g) | Tenant shall secure, pay for, and maintain during the continuance of its work within the Premises, policies of insurance with such coverages and such amounts as
Landlord may reasonably require, which policies shall be endorsed to include Landlord and its contractor and their respective employees and agents and Landlords mortgagees as additional insured parties and which shall provide thirty
(30) days prior written notice of any alteration or termination of coverage, in such amounts and insuring such risks as Landlord may require. Tenant shall not permit Tenants contractors to commence any work until all required insurance
has been obtained by Tenant and certificates evidencing such coverage have been delivered to Landlord; and

| | (h) | Tenants agents, subcontractors and vendors shall be required to conform with the Tenant/Contractor & Vendor Guidelines attached hereto as
Schedule B-2and made a part hereof.

| | (a) | Except as expressly set forth herein, Landlord has no other agreement with Tenant and has no other obligation to do any other work or pay any amounts with respect to
the Premises. Any other work in the Premises which may be permitted by Landlord pursuant to the terms and conditions of the Lease shall be done at Tenants sole cost and expense and in accordance with the terms and conditions of the Lease.

the Lease or otherwise, or to any portion of the original Premises or any additions thereto in the event of a renewal or extension of the initial term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in
the Lease or any amendment or supplement thereto.

WILLIS TOWER

TENANT/CONTRACTOR & VENDOR GUIDELINES

These guidelines have been developed by
building management of Willis Tower to provide information regarding procedures in the building. The purpose of these guidelines is to facilitate the completion of projects in a timely and safe manner. All rules of the building are expected to be
complied with, otherwise building management may take appropriate actions including stopping a project.

Cooperation is essential and although
not all-possible situations can be foreseen, these guidelines deal with general areas of concern. Should any issue, not dealt with herein arise, contact building management in the Office of the Building during regular business hours or the Security
Command Center after hours.

It is expected that the contractor will abide by all laws and regulations, including City of Chicago building
codes, OSHA, NFPA, and EPA guidelines.

Security for the area during construction work is the responsibility of the contractor. This extends
to possessions as well as the securing of the area upon completion of the work period. All temporary locking devices are to be provided by the building locksmith.

We expect a contractor working in our building to realize that he and his employees are invited guests and will be expected to exercise good judgment and courtesy at all times. Furthermore, be aware that
many other businesses are operating within the building simultaneously and building management is committed to providing them with a quiet, clean, and safe environment.

Management reserves the right to halt or delay any work in the building if we determine that the work interferes with our tenants ability to reasonably conduct their business. All loud noise related
work shall be completed prior to 8:00 a.m. or after 6:00 p.m. Any and all work that results in noise affecting areas in the building other than the floor under construction, including but not limited to concrete coring or sawing, hammering,
drilling, shooting of ceiling hangers, cutting of pipes along the columns or within the concrete slab, shall be done before or after regular business hours or on weekends.Security measures will be taken if required to assure compliance.

Contractor will be responsible for the repair of any damage to the Building or common areas caused by Contractor during construction. All
carpet, walls, ceiling and common areas must be returned to the condition existing prior to construction. Plastic runners and masonite must be laid prior to construction start. Duct tape masonite seams. Walk off mats required at all exit points
of construction area.

When after-hours work is required, building management and the Life Safety department must be notified no later
than 2 hours prior to the close of business on the preceding business day. Also, arrangements must be made at this time for freight elevator or rubbish removal service. See Contractor After Hours Building Access Authorization Form attached.

Prior to the start of work, the General Contractor must submit 1. the permit, 2. insurance certificates and endorsements, and 3. the names
and addresses of all subcontractors, together with the name and telephone number of a contact person for each subcontractor to the building Construction Manager.Also, the General Contractor must introduce the job superintendent to the
