promptly when due, in cash or by check, in lawful money of the United States of America, without notice or demand and without deduction, diminution, abatement, counterclaim or set off of any amount or for any reason whatsoever, payable to Landlord
c/o Polinger Shannon & Luchs Company, as Agent, and delivered to Polinger Shannon & Luchs Company at its offices at the address as stated in Article 26 or to such other person and place as may be designated by notice in
writing from Landlord to Tenant from time to time. If Tenant shall present to Landlord more than twice during any calendar year checks or drafts not honored by the institution upon which they are issued due to non-sufficient funds or closed account,
then Landlord may require that future payments of Basic Rent and Additional Rent and other sums thereafter payable be made by certified or cashiers check.



3.04 - All amounts other than Basic Rent required to be paid by Tenant to Landlord under the terms of this Lease and any charges or expenses
incurred by Landlord on behalf of Tenant under the terms of this Lease shall be considered additional rent (Additional Rent). Additional Rent payable pursuant to Articles 6 and 7 hereof shall be due and payable on the first day of each
month during the Tern together with installments of Basic Rent. Additional Rent other than that payable pursuant to Articles 6 and 7shall be due and payable within fifteen (15) days following receipt of a statement from Landlord of such

resolution of the dispute.



3.05 - Other remedies for
non-payment notwithstanding, any installment of rent which is not paid within ten (10) days after the due date shall be subject, at Landlords option each month, to a late charge equal to five percent (5%) of the amount due, which

announced by Citibank, N.A. from time to time as its prime rate (the Prime Rate) (but in no event higher than the maximum rate allowed by law) until paid in full, which interest shall be deemed Additional Rent hereunder; provided,
however, that prior to the imposition of such interest or such late charge, Landlord shall notify Tenant in writing of such late payment of rent and Tenant shall have five (5) days after such notice to make full payment of the installment of
rent then due; provided further, however, that Landlord shall be required to send such notice no more than two (2) times in any 12 month period; and provided further, however, that Landlords failure to deliver such notice shall in no way
limit Landlord in exercising any other remedies for non-payment.



3.06 - No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installments of rent herein stipulated shall be deemed to be other than on account of the earliest stipulated rent nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and Landlord may accept such check for payment without prejudice to Landlords right to recover the balance of such rent or to
pursue any other remedy provided in this Lease.



3.07 -
Tenants pro rata share of increases in Operating Expenses, as defined in Article 6, is agreed to be 16.67 percent. Tenants pro rata share of increases in Real Estate Taxes, as defined in Article 7, is agreed to be 16.67 percent.
Tenants pro rata share was calculated by dividing the rentable square feet of the Premises by the square footage of the Building, which is 176,563.



3.08 - It is agreed by Landlord and Tenant that no rent for the use, occupancy or utilization of the Premises shall be, or is, based in whole or in
part on the net income or profits derived by any person from the Building , Project or the Premises, and Tenant further agrees that it will not enter into any sublease, license, concession or other agreement for any use, occupancy or utilization of
the Premises which provides for rent or other payment for such use, occupancy or utilization based in whole or in part on the net income or profits derived by any person from the



3



---

Premises so leased, used, occupied or utilized. Nothing in the foregoing sentence, however, shall be construed as permitting or constituting Landlords
approval of any sublease, license, concession, or other use, occupancy, or utilization agreement not otherwise approved by Landlord in accordance with the provisions of Section 15.01 hereof.



USE OF PREMISES 4.01 - Tenant covenants to use the Premises only for
general office use and/or to carry on the business of classroom training for advanced information technology professionals in information technology (Professional Classroom Training) and for no other purpose, subject to and in accordance
with all applicable zoning and other zoning and other governmental regulations. Tenant, at its own expense, shall comply with and promptly carry out all orders, requirements or conditions imposed by the ordinances, laws and regulations of all of the

Premises.



4.02 - Tenant accepts the Premises and the
rest of the Project from Landlord in as is condition, except to the extent specifically provided elsewhere in this Lease.



4.03 - Tenant shall not permit the Premises, or any part thereof, to be used for general public education or for any disorderly, unlawful or
hazardous purpose, nor as a source of annoyance or embarrassment to Landlord or other tenants, nor for any purpose other than herein before specified, nor for the manufacture of any commodity therein, without the prior written consent of Landlord.



4.04 - Landlord hereby reserves to itself and its
successors and assigns the following rights (all of which are hereby consented to by Tenant): (i) to change the lobby, street address and/or name of the Building and/or the arrangement and/or location of entrances, passageways, doors, doorways,
corridors, elevators, stairs, toilets, or other public parts of the Building, (ii) to control and operate the public portions of the Building and the public facilities, as well as facilities furnished for the common use of the tenants, in such
a manner as it deems appropriate for the benefit of tenants generally, and (iii) to erect, use and maintain pipes and conduits in and through the Premises (but in a manner so as to minimize interference with Tenants use thereof), and
Landlord may exercise any or all of the foregoing rights without being deemed to be guilty of an eviction, actual or constructive, or a disturbance or interruption of the business of Tenant or Tenants use or occupancy of the Premises.



COST OF LIVING ADJUSTMENT 5.01 - Effective on the first
day of the second Lease Year, and on the first day of each subsequent Lease Year so long as this Lease remains in effect, the Initial Basic Rent set forth in Article 3 shall be increased on an annual basis; and Tenant covenants to pay Landlord,

the immediately preceding Lease Year, as more particularly set forth in Exhibit D attached hereto.

OPERATING EXPENSES-ESCALATION 6.01 - Tenant shall pay to Landlord, as
Additional Rent, Tenants pro rata share, as specified in Section 3.07, of the amount by which the Operating Expenses for the Comparison Year exceed the Operating Expenses for the Base Year (adjusted to reflect a one hundred percent

Expenses in such Comparison Year exceed the Operating Expenses in the Base Year, multiplied by (ii) a fraction, the numerator of which is the number of days from the Lease Commencement Date through



4



---

December 31, 1997 and the denominator of which is 365. In the event the Building is not at least one hundred percent (100%) occupied in the Base
Year or any Comparison Year, Operating Expenses for the Base Year and such Comparison Year shall be adjusted by Landlord to be equal to the amounts which would have been incurred in Landlords reasonable judgment if the Building had been one
hundred percent (100%) occupied. All operating expenses to be included in the Base Year shall be calculated without regard to any rental abatements provided to Tenant or other tenants of the Building, or vacancies in excess of five percent

opinion of Landlord or the mortgagee of Landlord, the amount of public liability and property damage insurance coverage at that time is not adequate in accordance with industry standards.



14.04 - All insurance required under this Lease shall be issued by insurance companies licensed to do business in the
jurisdiction where the Building of which the Premises is a part is located. Such companies shall have a policyholder rating of at least A and be assigned financial size category of at least Class VIII as rated in the most
recent edition of Bests Key Rating Guide for insurance companies. Each policy shall contain an endorsement requiring thirty days written notice from the insurance company to Landlord before cancellation or any change in the
coverage, scope or amount of any policy. Each policy, or a certificate showing it is in effect, together with evidence of payment of premiums, shall be deposited with Landlord at the commencement of the Lease, and renewal certificates or copies of
renewal policies shall be delivered to Landlord at least thirty days prior to the expiration date of any policy.



14.05 - If any of the Landlords insurance policies shall be cancelled or cancellation shall be threatened or the coverage thereunder reduced
or threatened to be reduced in any way because of the use of the Premises or any part thereof by Tenant or any assignee or subtenant of Tenant or by anyone Tenant permits on the Premises, and if Tenant fails to remedy the condition within two
(2) business days after notice thereof, Landlord may at its option, either terminate this Lease or enter upon the Premises and attempt to remedy such condition, and Tenant shall promptly pay the cost thereof to Landlord. Landlord shall not be
liable for any damage or injury caused to any property of Tenant or of others located on the Premises from such entry.



14.06 - All policies covering real or personal property which either party obtains affecting the Premises shall include a clause or endorsement
denying the insurer any rights of



15



---

subrogation against the other party to the extent rights have been waived by the insured before the occurrence of injury or loss. Landlord and Tenant waive
any rights of subrogation or recovery against the other for damage or loss to their respective property due to hazards covered or which should be covered by policies of insurance obtained or which should be or have been obtained pursuant to this
Lease, to the extent of the injury or loss covered thereby, assuming that any deductible shall be deemed to be insurance coverage.



ASSIGNMENT AND SUBLETTING 15.01 - Tenant shall not assign, transfer, mortgage or encumber this Lease or sublet the Premises or allow the use of the
Premises or any part thereof by persons other than Tenant without obtaining the prior written consent of Landlord, nor shall any assignment or transfer of this Lease be effectuated by operation of law or otherwise without the prior written consent
of Landlord, which consents (a) shall not be unreasonably withheld conditioned or delayed, and (b) shall not be required in the event of a sublease by Tenant of one (1) office to a client (but not more than an aggregate of three
(3) offices).



Tenant shall not assign this Lease, sublet
the Premises, or permit occupancy or use of the Premises or any part thereof by another party or parties, without giving Landlord fifteen (15) business days written notice of Tenants bona fide proposed assignment or subletting of all or
any part of the Premises. Landlord shall have the right, at its option during said fifteen (15) business day period, either to release Tenant from its Lease for only such space or to sublet all or any part of such space from the Tenant at the
same rental Tenant is paying Landlord, with the right to further sublease such space (but only if Tenant shall propose to assign or sublet any space which either separately or combined with other space assigned or sublet by Tenant shall equal or
exceed in the aggregate twenty percent (20%) of the Premises), or to reasonably refuse to consent to Tenants assignment or subletting of such space (no matter its size) and to continue this Lease in full force and effect as to the entire
Premises.



In the event Landlord does not respond in some
fashion (including without limitation requesting any information regarding the proposed sublease) to Tenants written request for consent within said fifteen (15) business day period, then Landlords consent shall be deemed given.



The consent by Landlord to any assignment, transfer, or
subletting to any party other than Landlord shall not be construed as a waiver or release of Tenant from the terms of any covenant or obligation under this Lease, nor shall the collection or acceptance of rent from any such assignee, transferee,
subtenant or occupant constitute a waiver or release of Tenant from any covenant or obligation contained in this Lease, nor shall such assignment or subletting be construed to relieve Tenant from giving Landlord said fifteen (15) business days
notice, nor from obtaining the consent in writing of Landlord to any further assignment or subletting.



In the event that Tenant defaults hereunder, Tenant hereby assigns to Landlord the rent due from any subtenant of Tenant and hereby authorizes each such
subtenant to pay said rent directly to Landlord. If Landlord consents to an assignment or sublease pursuant to this Section 15.01, Tenant shall provide Landlord with an executed copy of such assignment or sublease within ten days of its
execution.



Notwithstanding any other provision contained
herein, Tenant shall be permitted to assign or sublet the Premises to any wholly-owned subsidiary of Tenant or to the parent (if any) of Tenant. For purposes of the foregoing, a transfer, conveyance, grant or pledge, directly or indirectly, in one
or more transactions, of interest in Tenant (whether stock, partnership interest or other form of ownership or control), or the issuance of new interests by which an aggregate of more than fifty percent (50%) of the interest in Tenant shall be
vested in a party or parties who are not holders of such interest(s) as of the date hereof shall be deemed an assignment of this Lease; provided, however, that this limitation shall not apply to any corporation, all the outstanding voting stock of
which is listed on a national securities exchange as defined in the Securities Exchange Act of 1934. The merger or consolidation of Tenant into or with any other



16



---

entity, or the sale of all or substantially all of Tenants assets, shall be deemed to be an assignment within the meaning of this Article.



Landlords acceptance of any name for listing on the Building
directory will not be deemed, nor will it substitute for Landlords consent to any sublease, assignment or other occupancy of the Premises.



In the event of an assignment or subletting not in conformance with the terms of this Lease, such assignment and/or subletting, at Landlords option,
shall be void ab initio and Landlord shall have the right to terminate this Lease or to require that the Premises be surrendered to Landlord for the balance of the Term (in the case of an assignment) or for the term of the proposed sublease (in the
case of a sublease). Such termination shall in no event be construed to limit Landlords right to damages or any other relief for the violation of the terms of this Lease.



In the event that Landlord approves an assignment or subletting of all or any portion of the Premises, Tenant shall pay from
time to time to Landlord as Additional Rent an amount (the Assignment or Sublet Premium) equal to fifty percent (50%) of the difference between (a) all sums paid to Tenant or its agent by or on behalf of such assignee or
subtenant under the assignment or sublease and (b) the Basic Rent and Additional Rent paid by Tenant from time to time under this Lease and attributable to the portion of the Premises assigned or sublet. Reasonable brokerage fees and
commissions, inducements (including free rent), and costs of alterations in and to the Premises required by such assignee or subtenant and approved by Landlord as hereinabove required shall be deducted prior to calculating the Assignment or Sublet
Premium due Landlord.



15.02 - Notwithstanding anything
to the contrary contained herein, no assignment or subletting by Tenant, nor any other transfer or vesting of Tenants interest hereunder (whether by merger, operation of law or otherwise), shall be permitted if:



(a) Landlord, or any person designated by Landlord as having an interest
therein, directly or indirectly, controls, is controlled by, or is under common control with (i) the proposed assignee, sublessee or successor-in-interest of Tenant or (ii) any person which, directly or indirectly, controls, is controlled
by or is under common control with, the proposed assignee, sublessee or successor-in-interest of Tenant;



(b) the proposed assignment or sublease (i) provides a rental or other payment for the leasing, use, occupancy or utilization of all or any portion
of the Premises based, in whole or in part, on the income or profits derived by any person from the property so leased, used, occupied or utilized other than an amount based on a fixed percentage or percentages of gross receipts or sales or
(ii) does not provide that such assignee or subtenant shall not enter into any lease, sublease, license, concession or other agreement for the use, occupancy or utilization of all or any portion of the Premises which provides for a rental or
other payment for each use, occupancy or utilization based, in whole or in part, on the income or profits derived by an person from the property so leased, used, occupied or utilized other than an amount based on a fixed percentage or percentages of
gross receipts or sales; or



(c) in the reasonable opinion of
Landlord, such proposed assignment, subletting or other transfer or vesting of Tenants interest hereunder (whether by merger, operation at law or otherwise) will (i) cause a violation of the Employee Retirement Income Security Act of 1974
by Landlord, or by any person which, directly or indirectly, controls, is controlled by, or is under common control with, Landlord or any person who controls Landlord or (ii) result or may in the future result in Landlord, or any person which,
directly or indirectly, has an interest in Landlord, receiving unrelated business taxable income (as defined in the Internal Revenue Code).

LANDLORDS RIGHT OF ACCESS 16.01 - Landlord may, at any time during Tenants occupancy
during reasonable business hours and upon reasonable prior oral or written notice to Tenant (except in the event of an emergency) enter the Premises for any reason, including without limitation to view the Premises, to facilitate repairs to the
Building, or to introduce, replace, repair, alter or make new or change existing connections from any fixtures, pipes, wires, ducts, conduits or other construction therein, or remove, without being held responsible therefor, placards, signs,
lettering, window or door coverings and the like not expressly consented to by Landlord. Landlord agrees to use reasonable efforts to minimize interference with Tenants use and occupancy of the Premises in exercising Landlords rights
under this Section 16.01.



16.02 - During the last
nine (9) months of the Term or any Renewal Term, Landlord may enter the Premises upon twenty-four (24) hours prior oral or written notice to Tenant to show the Premises to prospective tenants at times which shall not unreasonably interfere
with Tenants business. If Tenant shall vacate the Premises during the last month of the Term, Landlord shall have the unrestricted right to enter the same after Tenants moving to commence preparations for the succeeding tenant or for any
other purpose whatsoever, without affecting Tenants obligation to pay rent for the full term. Landlord, in exercising its rights set forth in this Section 16.02, shall be responsible for any damage to Tenants property located in the
Property solely caused by Landlords actions.



FIRE
CLAUSE 17.01 - In the event the Premises or any part thereof, the elevators, hallways, stairways or other approaches thereto, becomes damaged or destroyed by fire or other casualty from any cause so as to render said Premises and/or approaches
unfit for use and occupancy, Tenant shall be required to pay the Rent only for the portion of the Premises that is usable for Tenant to conduct its business while such repair and restoration are being made until said Premises and/or approaches have
been put in as good condition for use and occupancy as at the time immediately prior to such damage or destruction. Landlord shall proceed, at its expense and as expeditiously as may be practicable, to repair the damage, unless, because of the
extent of the damage or destruction, Landlord should decide not to repair or restore the Premises or the Project, in which event and at Landlords sole option, Landlord may terminate this Lease forthwith by giving Tenant a written notice of its
intention to terminate within ninety (90) days after the date of the casualty. Landlord shall not be obligated to repair, restore or replace the contents of the Premises, including without limitation, any fixture, improvement, alteration,
furniture or other property owned, installed or made by or on behalf of Tenant, all of which shall be repaired, restored or replaced by Tenant.



17.02 - Tenant shall immediately notify Landlord of any damage to the Premises caused by fire or any other casualty.



17.03 - No damages, compensation, or claim shall be payable by
Landlord for inconvenience, loss of business, or annoyance arising from any repair or restoration of any portion of the Premises or the Project. Subject to the provisions of Sections 17.01 and 17.04 hereof, Landlord shall diligently proceed to have
such repairs made promptly.



17.04 - Notwithstanding
anything herein to the contrary, Landlord shall not be obligated to restore the Premises or the Project and shall have the right to terminate this Lease if (a) the holder of any mortgage fails or refuses to make insurance proceeds available for
such repair and restoration, (b) zoning or other applicable laws or regulations do not permit such repair and restoration, or (c) the cost of repairing and restoring the Building would exceed fifty percent (50%) of the replacement
value of the Building, whether or not the Premises are damaged or destroyed.



18



---

CONDEMNATION 18.01 - This Lease shall be terminated and the rental payable hereunder shall be
abated to the date of such termination in either of the following events:



(a) condemnation of the Premises, Building or Project or any part thereof by any competent authority under right of eminent domain for any public or quasi-public use or purpose; and



(b) the condemnation by competent authority under right of eminent domain
for any public or quasi-public use or purpose of twenty-five percent or more of the Project in which the Premises are located. The forcible leasing by any competent authority of any portion of the Project other than the Premises shall have no effect
upon this Lease.



In case of any taking or
condemnation, whether or not the Term shall cease and terminate, the entire award shall be the property of Landlord except as provided in the next succeeding sentence, and Tenant hereby assigns to Landlord all its right, title and interest in and to
any such awards. Tenant, however, shall be entitled to claim, prove and receive in any condemnation proceedings such awards as may be allowed for improvements, alterations, fixtures other equipment installed by it and relocation expenses, but only
if such awards shall be made by the court in addition to the award made by it to Landlord for the land and the Project or part thereof so taken.



18.02 - In the event of a temporary taking or condemnation of all or any part of the Premises for any public or quasi-public use or purpose, this
Lease shall be unaffected and Tenant shall continue to pay in full Initial Basic Rent, Basic Rent and all Additional Rent payable for any such period. In the event of any such temporary taking notwithstanding the provisions of Section 18.01,
Tenant shall be entitled to claim, prove and receive the portion of the award for such taking that represents compensation for use or occupancy of the Premises during the Term, and Landlord shall be entitled to appear, claim, prove and receive the
portions of the award that represent the cost of restoration of the Premises and the use or occupancy of the Premises after the end of the Term.



DEFAULTS AND REMEDIES 19.01 - It is hereby mutually agreed that:



(a) if Tenant shall fail to keep and perform each and every covenant, condition and agreement herein contained on the part
of Tenant to be kept and performed; or



(b) if Tenant shall
abandon or evidence any intention to abandon all or any portion of the Premises; or



(c) if the estate hereby created shall be taken by execution or other process of law; or



(d) if Tenant shall (i) generally not pay Tenants debts as such debts become due, (ii) become insolvent, (iii) make an assignment for
the benefit of creditors, (iv) file, be the entity subject to, or acquiesce in a petition in any court (whether or not filed by or against Tenant pursuant to any statute of the United States or any state and whether or not for a trustee,
custodian, receiver, agent, or other officer for Tenant or for all or any portion of Tenants property) in any proceeding whether bankruptcy, reorganization, composition, extension, arrangement, insolvency proceedings, or otherwise; and
(A) in the event of a monetary default including without limitation the failure to pay Initial Basic Rent, Basic Rent or Additional Rent, such failure shall continue for five (5) days after the due date or (B) in the event of all
other defaults hereunder (except (b), (c), and (d), above (which require no notice whatsoever)) such failure shall continue after written notice and the expiration of thirty (30) days (unless Tenant has commenced to cure such breach or failure
within such thirty-day period and is diligently pursuing said cure in which event such thirty (30) days shall be extended so long as Tenant diligently pursues such cure but in no event shall such cure period be extended for more than an
additional sixty (60) days), then, and in each and every such case (each case hereinafter defined as a default), from thenceforth and at all times thereafter, at the sole option of Landlord, Landlord may:



(a) Terminate this Lease, in which event Tenant shall
immediately surrender the Premises to Landlord. If Tenant fails to do so, Landlord may,



19



---

without notice and without prejudice to any other remedy Landlord may have, enter upon and take possession of the Premises and expel or remove Tenant and its
effects without being liable to prosecution or any claim for damages therefor; and Tenant shall indemnify and hold Landlord harmless for all loss or damage and cost (including attorneys fees and court costs) which Landlord may suffer by reason
of such termination, whether through the inability to relet the Premises or otherwise including any loss of rental for the remainder of the Term.



(b) Terminate this Lease, in which event Tenants default should be considered a total breach of Tenants obligations under this
Lease and Tenant immediately shall become liable for such damages for such breach, in an amount equal to the total of (1) the costs of recovering the Premises; (2) the unpaid rental earned as of the date of termination, plus interest
thereon at a rate per annum from the due date equal to three percent (3%) over the Prime Rate, provided, however, that such interest shall never exceed the highest lawful rate; and (3) all other sums of money and damages owing by Tenant to
Landlord. Tenants right of possession shall cease and terminate and Landlord shall be entitled to the possession of the Premises and shall remove all persons and property therefrom and reenter the same without further demand of rent or demand
of possession of the Premises, either with or without process of law and without becoming liable to prosecution therefor, any notice to quit or intention to reenter being hereby expressly waived by Tenant. In the event of reentry or retaking by
Landlord, Tenant shall nevertheless remain in all events liable and answerable for the full rental to the date of retaking or reentry, and Tenant shall also be and remain answerable in damages for the deficiency or loss of rent as well as all
related expenses which Landlord may thereby sustain in respect to the balance of the term; and in such case Landlord reserves full power, which is hereby acceded to by Tenant, to let said Premises for the benefit of Tenant, in liquidation and
discharge, in whole or in part, as the case may be, of the liability of Tenant under the terms and provisions of this Lease, and such damages and related expenses, at the option of Landlord, may be recovered by it at the time of the retaking and
reentry, or in separate actions, from time to time, as Tenants obligation to pay rent would have accrued if the Term had continued, or from time to time as said damages and related expenses shall have been made more easily ascertainable by
reletting of the Premises, or such action by Landlord may, at the option of Landlord, be deferred until the expiration of the Term, in which latter event the cause of action shall not be deemed to have accrued until the date of the termination of
said Term.



(c) Declare the present worth (as
of the date of such default) of the entire balance of Initial Basic Rent, Basic Rent and Additional Rent for the remainder of the Term to be due and payable, and collect such balances in any manner not inconsistent with applicable law. For the
purpose of this Section 19.01(c), present worth shall be computed by discounting the entire balance to present worth at a discount rate equal to the discount rate then in effect at the Federal Reserve Bank nearest the location of
the Building.



(d) Pursue any combination of
such remedies and/or other remedy available to Landlord on account of such default under applicable law. All remedies and rights of Landlord herein and or at law or equity are separate, distinct and cumulative and no one of them, whether exercised
or not, shall be deemed to be in exclusion of any of the others.



19.02 - The provisions of this Article 19 are subject to the Bankruptcy Laws of the United States of America which may, in certain cases, limit the rights of Landlord to enforce



20



---

some of the provisions of this Article in proceedings thereunder. To the extent that limitations exist by virtue thereof, the remaining provisions hereof
shall not be affected thereby but shall remain in full force and effect. The provisions of this Article 19 shall be interpreted in a manner which results in a termination of this Lease in each and every instance, and to the fullest extent and at the
earliest moment that such termination is permitted under the federal bankruptcy laws, it being of prime importance to the Landlord to deal only with Tenants who have, and continue to have, a strong degree of financial strength and financial
stability.



19.03 - All rents received by Landlord in
any reletting after Tenants default shall be applied, first to the payment of such expenses as Landlord may have incurred in recovering possession of the Premises and in reletting the same (including brokerage fees), second to the payment of
any costs and expenses incurred by Landlord, either for making the necessary repairs (including fitting up the space for such reletting) to the Premises or in curing any default on the part of the Tenant of any covenant or condition herein made
binding upon Tenant. Any remaining rent shall then be applied toward the payment of Initial Basic Rent, Basic Rent and Additional Rent due from Tenant under the terms of this Lease, together with interest and penalties as defined in
Section 3.04, and Tenant expressly agrees to pay any deficiency then remaining. Landlord shall in no event be liable in any way whatsoever (nor shall Tenant be entitled to any set off) for Landlords failure to relet the Premises, and
Landlord, at its option, may refrain from terminating Tenants right of possession, and in such case may enforce against Tenant the provisions of this Lease for the full Term thereof.



19.04 - In the event Tenant defaults in the performance of any of the
terms, covenants, agreements or conditions contained in this Lease and Landlord places in the hands of an attorney or collection agency the enforcement of all or any part of this Lease, the collection of any Initial Basic Rent, Basic Rent and
Additional Rent due or to become due or recovery of the possession of the Premises, Tenant agrees to pay Landlords costs of collection and enforcement, including reasonable attorneys fees, whether suit is actually filed or not.



SUBORDINATION CLAUSE 20.01 - This Lease is and shall be
subject and subordinate at all times to all ground or underlying leases and to the lien of any mortgage or deed of trust encumbrance(s) which may now or which may at any time hereafter be made upon the Project of which the Premises is a part or any
portion thereof, or upon Landlords interest therein and to all renewals, modifications and extensions thereof. As a condition of subordination, Landlord shall provide to Tenant a nondisturbance agreement in a mortgagees, other secured
partys or ground lessors standard form, which Tenant hereby agrees to execute within ten (10) days of delivery. In confirmation of such subordination, Tenant shall execute and deliver such further instrument(s) subordinating this
Lease to the lien of any such ground lease, mortgage or deed of trust or any encumbrance(s) as shall be desired by any ground lessor, mortgagee or party secured or proposed to be secured or proposed to secured thereby. If the interests of Landlord
under this Lease shall be transferred by reason of foreclosure or other proceedings for enforcement of any mortgage or deed of trust on the Premises or Project, Tenant shall be bound to the transferee at the option of the transferee, under the
terms, covenants and conditions of this Lease for the remaining term, including any extensions or renewals, with the same force and effect as if the transferee were Landlord under this Lease, and, if requested by transferee, Tenant agrees to attorn
to the transferee as its Landlord.



Upon such attornment such
purchaser shall not be (a) bound by any payment of Rent more than one (1) month in advance, (b) bound by any amendment of this Lease made without the consent or the holder of the deed of trust existing as of the date of such
amendment, (c) liable for damages for any breach, act or omission of any prior landlord, or (d) subject to any offsets or defenses which Tenant might have against any prior landlord. Within ten (10) days after the request of such
purchaser, Tenant shall execute, acknowledge and deliver any requisite or appropriate document on the lenders standard form submitted to Tenant confirming such



21



---

attornment. The holder of any mortgage or deed of trust encumbering the Project shall have the right, unilaterally, at any time to subordinate fully or
partially its mortgage or deed of trust or other security instrument to this Lease on such terms and subject to such conditions as such holder may consider appropriate in its discretion. Upon request Tenant shall execute and deliver an instrument
confirming any such full or partial subordination. Landlord represents that at the time of the execution of this Lease that there is no mortgage or ground lease encumbering this Building.



20.02 - At the option of any landlord under any ground or underlying lease to which the Lease is now or may hereafter
become subject or subordinate, Tenant agrees that neither the cancellation nor termination of such ground or underlying lease shall by operation of law or otherwise, result in cancellation or termination of this Lease or the obligations of Tenant
hereunder. Tenant covenants and agrees to attorn to such landlord or to any successor to Landlords interest in such ground or underlying lease subject to the attornment provisions set forth above. In that event, this Lease shall continue as a
direct lease between Tenant and such landlord or its successor.



20.03 - After Tenant receives written notice from any person, firm or other entity that it holds a mortgage or deed of trust on the Building or the Project, no notice from Tenant to Landlord alleging any default by Landlord shall be
effective unless and until a copy of the same is given to such holder, provided that Tenant shall have been furnished with the name and address of such holder. Any such holder shall have thirty (30) days, or such additional time as may
reasonably be necessary, after receipt of notice from Tenant of a default by Landlord under this Lease to cure such default before Tenant may exercise any remedy hereunder. The curing of any of Landlords defaults by such holder shall be
treated as performance by Landlord.



SURRENDER OF POSSESSION
21.01 - Landlord hereby agrees that Tenant shall not be required to remove any of its improvements made prior to the Lease Commencement Date or any alterations which Landlord agrees may remain following expiration of this Lease. Tenant
covenants, at the expiration or other termination of this Lease, to remove all goods and effects from the Premises not the property of Landlord, to remove all alterations and restore the Premises to its state on the Lease Commencement Date, unless
Landlord has agreed in writing to allow such alterations to remain pursuant to Section 11.01 hereof, all at Tenants expense, and to yield up to Landlord the Premises and all keys, gate cards, parking passes, security cards, locks and
other fixtures connected therewith in good repair, order and condition in all respects, reasonable wear and use thereof and damage by fire or other casualty only excepted. At expiration, or other termination of this Lease, Tenant may remove from the
Premises the moveable walls, raised floor, trade fixtures, reception desks, A N equipment (including screen, monitors and projectors) security equipment, furniture and rooftop equipment (subject to the provisions of Section 31.01 of this Lease)
installed by or on behalf of Tenant. Any property of Tenant not promptly removed shall be deemed to have been abandoned by Tenant and to have become the property of Landlord and may be retained by Landlord or disposed of at Tenants expense
(Tenant hereby agreeing to remain liable for the cost thereof even though this Lease shall have terminated) as Landlord shall so desire except for improvements made prior to the Lease Commencement Date or Landlord approved alterations the disposal
of which shall not be at Tenants expense.



TENANT
HOLDING OVER 22.01 - If Tenant or any person claiming through Tenant shall not immediately surrender possession of the Premises at the termination of this Term, no tenancy or interest in the Premises shall result therefrom, but such holding over
shall be an unlawful detainer subject to immediate eviction and removal. Landlord shall be entitled to recover compensation for such use and occupancy at one hundred fifty percent (150%) of the Basic Rent and Additional Rent payable hereunder
just prior to the expiration or earlier termination of the Term. Landlord shall also continue to be entitled to retake or recover



22



---

possession of the Premises as herein before provided in case of default on the part of Tenant, and Tenant shall be liable to Landlord for any loss or damage
it may sustain by reason of Tenants failure to surrender possession of the Premises immediately upon the expiration or earlier termination of the Term. Tenant hereby agrees that all the obligations of Tenant and all rights of Landlord
applicable during the Term shall be equally applicable during such period of subsequent occupancy.



ESTOPPELS 23.01 - Tenant shall, without charge therefor, at any time and from time to time, within seven (7) days after request by Landlord,
execute, acknowledge and deliver to Landlord a written estoppel certificate certifying to Landlord, any mortgagee, assignee of a mortgagee, or any purchaser of the Project, or any other person designated by Landlord, as of the date of such estoppel
certificate:



(a) that Tenant is in possession of the
Premises;



(b) that this Lease is unmodified and in full force
and effect (or if there have been modifications, that the Lease is in full force and effect as modified and setting forth such modification);



(c) whether or not there are then existing any set-offs or defenses against the enforcement of any right or remedy of Landlord, or any duty or obligation
of Tenant hereunder (and, if so, specifying the same in detail);



(d) the amount of the Basic Rent and the dates through which Basic Rent and Additional Rent have been paid;



(e) that Tenant has no knowledge of any then uncured defaults on the part of Landlord under this Lease (or if Tenant has knowledge of any such uncured
defaults, specifying the same in detail);



(f) that Tenant has
no knowledge of any event having occurred that authorizes the termination of this Lease by Tenant (or if Tenant has such knowledge, specifying the same in detail);



(g) the amount of any Security Deposit held by Landlord;



(h) stating the commencement and expiration dates of the Lease and any options to renew said Lease; and



(i) such reasonable other information requested by mortgagee, assignee of
such mortgagee, such purchaser or such other person. Failure to deliver the certificate within ten (10) business days after request by Landlord shall be conclusive upon Tenant for the benefit of Landlord and any successor to Landlord that this
Lease is in full force and effect and has not been modified except as may be represented by the party requesting the certificate.



If Tenant fails to deliver the certificate within the ten (10) business days after requested by Landlord, then such failure by Tenant shall be a
default hereunder and, in addition Tenant shall be deemed to have irrevocably constituted and appointed Landlord as its special attorney in fact to execute and deliver the certificate to any third party; provided, however, that other than acting as
Tenants attorney-in-fact, Landlords sole remedy for Tenants default in the failure to timely deliver the certificate shall be an action for declaratory judgment or specific performance.



MISCELLANEOUS 24.01 - The term Tenant shall include legal
representatives, successors and assigns. All covenants herein made binding upon Tenant shall be construed to be equally applicable to and binding upon its agents, employees and others claiming the right to be in the Premises or in the Project
through or under Tenant.



24.02 - If more than one
individual, firm, or corporation shall join as Tenant, singular context shall be construed to be plural wherever necessary and the covenants of Tenant shall be the joint and several obligations of each party signing as Tenant and when the parties
signing as Tenant are partners, shall be the obligation of the firm and of the individual members thereof.



23



---

24.03 - Feminine or neuter pronouns shall be substituted for those of the masculine form and the
plural shall be substituted for the singular, wherever the context shall require. It is also agreed that no specific words, phrases or clauses herein used shall be taken or construed to control, limit or cut down the scope or meaning of any general
words, phrases or clauses used in connection therewith.



24.04 - No waiver or breach of any covenant, condition or agreement herein contained shall operate as a waiver of the covenant, condition or agreement itself, or of any subsequent breach thereof. No failure of Landlord to exercise
any power given Landlord hereunder, and no custom or practice of the parties at variance with the terms hereof shall constitute a waiver of Landlords right to demand exact compliance with the terms hereof. Receipt by Landlord or any Basic
Rent, Additional Rent or other sums payable hereunder with knowledge of the breach of any provision hereof shall not constitute a waiver of any such breach nor shall acceptance by Landlord of partial payments or partial performance constitute accord
and satisfaction. No waiver by Landlord of any provision hereof shall be deemed to have been made unless made in writing and a waiver so given on one occasion shall not be deemed a waiver on any subsequent occasion.



24.05 - Notwithstanding anything to the contrary contained in this
Lease, Tenant shall look only to Landlords ownership in the Project (including proceeds of sale, insurance or condemnation if a legitimate claim is made by Tenant within sixty (60) days of notice of such sale, casualty or condemnation)
for satisfaction of Tenants remedies for the collection of a judgment (or other judicial process) requiring the payment of money by Landlord in the event of any default by Landlord hereunder, and no other property or assets of the partners or
principals of Landlord, disclosed or undisclosed, shall be subject to levy, execution or the enforcement procedure for the satisfaction of Tenants remedies under or with respect to this Lease, the relationship of Landlord and Tenant hereunder

QUIET ENJOYMENT
27.01 - Landlord covenants and agrees that upon Tenant paying the rent and Additional Rent and observing and performing all the terms, covenants and conditions, on Tenants part to be observed and performed, Tenant may peaceably and quietly
enjoy the Premises hereby demised, subject, nevertheless, to the terms and conditions of this Lease and to any mortgages and deeds of trust hereinbefore mentioned.



WAIVER OF TRIAL BY JURY 28.01- LANDLORD AND TENANT EACH AGREE TO AND THEY HEREBY DO WAIVE TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER ON ANY MATTERS WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE THE RELATIONSHIP OF LANDLORD AND TENANT, TENANTS USE OR OCCUPANCY OF
THE PREMISES AND/OR ANY CLAIM OF INJURY OR DAMAGE, AND ANY STATUTORY REMEDY.



26



---

GOVERNING LAW 29.01 - This Lease shall be construed and governed by the laws of the state in which
the Premises are located. Should any provision of this Lease and/or its conditions be illegal or not enforceable under the laws of said state, it or they shall be considered severable, and the Lease and its conditions shall remain in force and be
binding upon the parties hereto as though the said provision had never been included.



PARKING 30.01 - While Tenant is occupying the Premises and is not in default under the terms of this Lease, Tenant shall have the right to utilize four (4) parking spaces in the Buildings parking
garage per 1,000 rentable square feet of the Premises, as expanded from time to time pursuant to the terms of this Lease, subject to reasonable rules and regulations promulgated from time to time by Landlord. Tenant may use such spaces on a daily or
monthly basis. The initial monthly and daily parking rates shall be $50.00 and $2.50 per space respectively, which rates shall increase by no more than 2.25% of the rate charged in the immediately preceding Lease Year. Monthly parking rental shall
be paid on or before the first day of each calendar month during the Term and may be adjusted from time to time, upon at least thirty days prior written notice to Tenant. With regard only to twenty-five percent (25%) of such parking spaces (the
Excess Spaces), Tenant shall be entitled only to that number of spaces that Tenant shall request from Landlord on thirty (30) days prior written notice or has agreed to accept on the lease execution date and has paid for on or
prior to the Lease Commencement Date. In addition, if Landlord determines in Landlords sole discretion that additional parking spaces are available, Tenant shall have the limited right to lease such spaces on a monthly basis at the rate per
space then charged to Tenant for parking spaces hereunder, provided, however, that Landlord shall have the right at any time, and from time to time, to terminate Tenants limited right to such parking spaces upon thirty (30) days
prior written notice to Tenant. Landlord and/or Landlords parking management company and Tenant shall make reasonable efforts to work with each other to try and achieve mutually satisfactory parking arrangements. Nothing herein contained shall
be construed to grant to Tenant any estate in real property nor the exclusive right to a particular parking space, but rather as a license only. At such time and under such circumstances as Landlord deems appropriate, Landlord may rearrange assigned
parking spaces or may eliminate assigned space altogether and may provide attendant parking or such other system or management of parking as it deems necessary or desirable. Tenant covenants and agrees to comply with all reasonable rules and
regulations which Landlord or the contract manager may make hereafter from time to time with respect to the use of the parking areas. Landlords remedies under such rules and regulations may include, but shall not be limited to, the right to
tow away at owners expense any vehicles not parked in compliance with these rules and regulations. Landlord shall not be responsible to Tenant for the noncompliance or breach of such rules and regulations by any other tenant, its agents,
employees and invitees or members of the public who may park in the parking areas.



ROOF TOP RIGHTS 31.01 - Subject to and in accordance with the conditions hereinafter set forth, Landlord hereby grants to Tenant the right to install, maintain and operate, at Tenants sole cost, air
conditioning equipment and communications equipment on the roof of the Building in accordance with specifications and at a location determined by Landlord (the Equipment). There shall be no rent charged to Tenant for these rights.



The right granted to Tenant pursuant to this
Section 31.01 shall be subject at all times to the following conditions: (i) prior to any installation of the Equipment, Tenant, at its cost and expense, shall obtain all required permits, licenses, approvals and other governmental
authorizations in connection with the installation, operation and use of said Equipment, and Tenant shall thereafter maintain the same in full of force and effect, (ii) all cots and expenses incurred in installing, operating, maintaining,
repairing, replacing and removing such Equipment shall be borne solely by Tenant, (iii) Tenant shall throughout the period of such installation, and



27



---

thereafter during any maintenance, repair or replacement of such equipment, install and utilize, at Tenants sole expense, screening supports, walk
boards, and such other materials as may be reasonably required to protect the roof of the Building, the Building generally, pedestrians, vehicles on adjacent roadways and any other property of adjacent property owners (iv) no equipment that
impairs the structure, value, rental value or rentability of, or unreasonably detracts from the appearance of, the Building, the Land, the Project or any part thereof shall be installed or operated by Tenant, (v) no equipment may be installed
or operated that would interfere with or disturb any other tenants quiet enjoyment of its space in the Building, (vi) no equipment may be installed or operated that interferes with any other equipment in the Building, and the equipment
originally installed by Tenant (which Tenant shall not change in specifications or manner of use) shall not interfere with any other equipment owned by any other person, irrespective of whether such person has any interest in the Building and
regardless of where such other equipment is located, (vii) Tenant shall have no right to sublease, license or otherwise allow the use of space on the roof by parties other than Tenant, (viii) Tenant and the Equipment shall not interfere
with any use of the roof by Landlord or any tenant of Landlord, or other person or entity permitted by Landlord to use the roof of the Building, (ix) if so requested by Landlord, at the expiration or other termination of this Lease the
Equipment installed or operated by Tenant shall be removed by Tenant at Tenants expense and any damage caused by such removal shall be promptly repaired by Tenant, (x) Tenant shall indemnify, protect, defend and hold Landlord, its agents
and employees harmless from and against any loss, cost, liability, damage or expense (including, but not limited to, attorneys fees and court costs) arising out of the installation, operation, use, maintenance (or failure to maintain), repair
or replacement (or failure to repair or replace), or removal (or failure to remove) of the Equipment installed or operated at the Building by Tenant, (xi) without limiting the foregoing indemnity, Tenant shall, at its expense, obtain and
maintain in effect such policy or policies of insurance in connection with the Equipment as Landlord shall reasonably require, and (xii) the installation of the Equipment shall not penetrate or otherwise damage the roof of the Building, and
Tenant shall be liable for any incidental damage thereby caused.



Tenant, as a material inducement to Landlord to grant Tenant the rights set forth in this Section 31.01 with respect to the Equipment, hereby represents and warrants to Landlord that (A) the Equipment which Tenant will install on
the roof of the Building will not impair the structure of the Building, and that such Equipment shall at all times satisfy all of the criteria set forth in clauses (i) through (xii) of this Section 3 1.01, and (B) to the extent
that the Equipment or any part thereof does violate any of the criteria set forth in said clauses (i) through (xii) of this Section 3 1.01, Tenant shall, upon any notice to it of such circumstance, immediately commence to cure the
violation of said criteria and shall thereafter expeditiously complete said cure.



Notwithstanding the foregoing, Landlord reserves the right to relocate or remove the Equipment if, in Landlords sole judgment and discretion, the Equipment shall compromise the integrity of the roof or any other
portion of the Building or shall impair the warranty held by Landlord with respect to the roof of the Building. Landlord has not made and does not make any representation, warranty or other statement to Tenant (and none of the same is in any way
implied) to the effect that installation, use or operation of any equipment by any other tenant of the Building, by Landlord, or by any other person or entity will not interfere with or impair Tenants installation, use or operation of the
Equipment, and Landlord shall have no obligation or liability whatsoever with respect to any such interference or impairment or any obligation or responsibility to take any action with respect to such interference or impairment.



If, for any reason, Tenant is unable to install, operate or use such
Equipment as set forth in this Section 31.01, this Lease shall nonetheless remain in full force and effect, without diminution in Basic Rent, Additional Rent, or any other sum payable hereunder. Except as expressly provided in this
Section 31.01, no space on the roof of the Building shall be used by Tenant without the prior written consent of Landlord, which may be withheld for any reason.

(a) Landlord hereby grants to Tenant the right, exercisable at Tenants option to renew the Term of the Lease hereby
for one (1) term (Renewal Term) of sixty (60) months.



If exercised, and if the conditions applicable thereto have been satisfied, the Renewal Term shall commence on the day immediately following the day which is the end of the initial Term as provided in the Lease. The
right of renewal herein granted to Tenant shall be subject to, and shall be exercised in accordance with, the following terms and conditions:

time would be or become such a default, on the date the Renewal Option Notice is sent or any time thereafter up to and including the date the Renewal Term is to commence, then, at Landlords option, the Renewal Term shall not commence and the
Term (if not sooner terminated pursuant to the exercise of Landlords remedies under the Lease) shall expire on the date the Term would have expired without the exercise of such renewal right.



(5) If Tenant assigns or sublets the Premises in violation of the terms of
the Lease, this option to renew shall be null and void.



(b)
During the Renewal Term, all the terms, conditions, covenants and agreements set forth in the Lease shall continue to apply and be binding upon Landlord and Tenant, including without limitation (i) the pass-through to Tenant of increases in
Operating Expenses and Real Estate Taxes in excess of the Base Year and the Base Real Estate Taxes, respectively, as defined in the Lease, and (ii) the obligation to pay Basic Rent for each year of the Renewal Term in an amount equal to 102.25
multiplied by the Basic Rent being paid during the immediately preceding Lease Year (as set forth in Section 5.01 of the Lease). In no event shall Tenant have the right to renew the Term beyond the expiration of the Renewal Term provided for in
Section 32.01(a) or in the event the Lease is terminated as provided in the other provisions of the Lease.



TERMINATION OPTION 33.01 - Tenant shall have the right (the Termination Option) to terminate the Lease effective at the end of either
the fifth (5th) or the seventh (7th) Lease Year (the Anniversary Dates). If exercised, and if all the conditions applicable thereto have been satisfied, the Lease shall then
terminate and all obligations, rights, burdens and benefits shall be null and void except for those provisions which expressly survive termination. The Termination Option shall be subject to, and shall be exercised in accordance with, the following
terms and conditions:



(1) Tenant shall exercise its
Termination Option by giving Landlord written notice (Termination Option Notice) thereof not less than 270 days prior to the respective effective date of such Termination Option, which effective date shall be one of the Anniversary Dates
and shall be specified in the Termination Option Notice.



(2)
In the event the Termination Option Notice is not given timely as to be effective as of the end of the fifth (5th) Lease Year, Tenants Termination options shall hereinafter only be available as to be effective as of the end of the seventh
(7th) Lease Year. In the event the Termination Option Notice is not given timely as to be effective at the end of the seventh (7th) Lease Year, Tenants Termination Option shall be null and void and shall lapse and be of no further
force and effect.



(3) The Termination Option may be exercised
only with respect to all of the Premises.



29



---

(4) In the event there exists a monetary default by Tenant under the Lease on the date that the
Termination Option Notice is sent or at any other time thereafter up to and including the effective date then, at Landlords option, the Termination Option shall not be effective and the Term (if not sooner terminated pursuant to the exercise
of Landlords remedies under the Lease) shall not expire until the date the Term would have expired without the exercise of such Termination Option.



(5) Absent written notice from Tenant (as part of its Termination Option Notice) that Tenant has assigned or sublet the Premises or any portion thereof,
Tenant shall be deemed to have warranted that no subtenant or assignee has any rights to any of the Premises as of the effective date of such Termination Option, and Tenant shall indemnify, defend, protect and hold Landlord harmless from any losses,
claims, liabilities, costs (including attorneys fees and court costs) or damages arising from or in connection with any breach of such warranty.



(6) Not later than thirty (30) days prior to the Anniversary Date specified in the Termination Option Notice, (a) if it is to be effective as of
the end of the fifth (5th) Lease Year, Tenant shall pay to Landlord the amount of $792,701.00, and (b) if it is to be effective as of the end of the seventh (7th) Lease Year, Tenant shall pay the Landlord the amount of $497,573.00.



(7) If Tenants required payment (as set forth in
Section 33.01(6) above) shall not be paid prior to thirty (30) days before the Anniversary Date set forth in the Termination Option Notice, then, at Landlords option, such Termination Notice shall be null and void or Landlord may, in
its sole discretion, opt to treat such termination as effective (which choice shall be binding upon Tenant for all purposes hereunder) and may treat such failure to timely pay as a monetary default hereunder, in which event Landlord may exercise any
or all of the remedies available hereunder.



(8) Upon sending
the Termination Option Notice, Tenant forever waives and relinquishes any and all rights and options to renew the Lease, expand the Premises, lease any Additional Space and any other similar rights, benefits and privileges.



(9) Tenant agrees to execute and deliver to Landlord any documents reasonably
requested in order to evidence the termination of this Lease.



(10) Upon Tenants exercise of its Termination Option, such exercise shall be irrevocable and Tenant shall be required to surrender the Premises on the effective date thereof as if that date was the day after the last day of the Term
hereunder. Any failure by Tenant to vacate and abandon the property on the effective date thereof after exercise of such Termination Option shall be treated as a hold over hereunder without further action of a notice of any kind and Landlord shall
have all of its hold over remedies as provided hereunder and shall not be required to send any notice to Tenant regarding such hold over.



ATTORNEYS FEES 34.01 - All costs and expenses, including attorneys fees in a reasonable amount, incurred by Landlord or Tenant in enforcing
the obligations of either party under this Lease, shall be paid by the defaulting party to the prevailing party upon demand, once a default is determined to have occurred, whether by judgment or otherwise.
