The acceptance by Landlord of Rent or the cure of the default which initiated the operation of this paragraph shall not be deemed a waiver by Landlord of the provisions of this paragraph unless specifically so stated in writing by Landlord at the time of such acceptance.

(c)Concession Election. Tenant may, at Tenant’s option, be permitted to convert any amount of the Abated Rent to an additional Allowance, as defined in the Work Letter, by providing written notice of the amount of such election to Landlord not later than the start of construction of the Tenant’s Work (the “Concession Election”), TIME BEING OF THE ESSENCE.

In the event Tenant shall fail to timely provide the Concession Election, Tenant shall be deemed to have irrevocably waived the Concession Election hereunder, and the same shall be and become null, void, and of no further force or effect.

(b)Tenant is not in Default under this Lease either on the date of Tenant’s exercise of the Termination Option or, unless waived in writing by Landlord, on the Termination Date;

(c)Tenant pays to Landlord fifty percent (50%) of the Termination Fee (defined herein) together with delivery of the Termination Notice and the other fifty percent (50%) of the Termination Fee not later than thirty (30) days prior to the Termination Date, TIME BEING OF THE ESSENCE for each payment.

For purposes hereof, “Unamortized Additional Space Costs” shall be determined for any Offer Space or Expansion Space added to the Premises prior to the date Tenant delivers its Termination Notice (herein, “Additional Space”) (it being agreed and understood that Tenant has no right to exercise its Right of First Offer from and after the date Tenant delivers the Termination Notice), and shall mean an amount calculated in each instance by determining the unamortized amount, as of the Termination Date, of all allowances, tenant improvement costs, rental abatements, brokerage commissions and concessions actually paid or incurred by Landlord with respect to any Additional Space, amortized over a period equal to the actual term of demise for any such Additional Space (i.e., meaning from and after the respective Monthly Rent commencement date for any such Additional Space, following any abatement period with respect thereto, and through the expiration of the Term of this Lease) using an interest factor equal to the trailing average CPI Rate increase for the most recent three (3) years in which the CPI Rate is published prior to the date Tenant sends the Termination Notice, as defined below.

(e)Notwithstanding anything herein to the contrary, the Termination Option shall automatically terminate and become null and void upon the earlier to occur of: (a) the termination of Tenant’s right to possession of the Premises; and (b) the failure of Tenant to timely or properly exercise the Termination option or pay the Termination Fee.

Subject to the Landlord’s Work, Landlord Turnover Obligations and Final Space Plan Addendum, Landlord shall tender possession of the Premises to Tenant on the date of mutual execution and delivery of this Lease by Landlord and Tenant (“Possession Date”). Notwithstanding the above, Landlord shall not be required to deliver possession hereunder until Tenant has delivered the Security Deposit to Landlord pursuant to Sections 1(l) and 29, together with the proof of insurance required under Section 22. If, however, Landlord shall be unable to tender possession of the Premises to Tenant on the Possession Date for any reason, Landlord shall not be liable or responsible for any claims, damages, or liabilities in connection therewith or by reason thereof, and such failure shall not affect the validity of this Lease or otherwise affect the obligations of Tenant hereunder; provided, however, in such event, Landlord shall continue to use commercially reasonable efforts to deliver possession of the Premises as soon thereafter as reasonably practicable, subject to the Landlord’s Work, Landlord Turnover Obligations and the Final Space Plan Addendum.

For all purposes of this Lease and subject to the provisions of the Work Letter, Landlord’s Work, Landlord Turnover Obligations, Tenant shall take possession of and accept the Premises in an “As Is” condition, without any warranty as to the condition thereof. No agreement or promise of Landlord, or their respective agents or employees to alter, remodel, decorate, clean, or

Subject to the provisions of the Work Letter, Landlord’s Work, Landlord Turnover Obligations Tenant shall be deemed to have accepted possession of the Premises in its “as is” condition as of the Possession Date (provided that the foregoing shall not limit Landlord’s maintenance and repair obligations as described in Section 9(c) below).

(b)Tenant’s Work. Tenant acknowledges that the Tenant’s Work as set forth in the Work Letter may not be completed by the Commencement Date, and that this circumstance shall not postpone the Commencement Date, or affect Tenant’s obligation to pay Rent, or make Landlord or its agents or contractors liable for any damage, loss, liability, or expense caused Tenant thereby. Subject to Landlord’s Work, Landlord Turnover Obligations and to Landlord’s obligations under Sections 8 and 9 of this Lease, Tenant shall, at its sole cost and expense, perform such work as may be necessary or desired by Tenant to improve the Premises for occupancy, all subject to and in accordance with the provisions of the Work Letter and this Lease, including, without limitation, the provisions of Section 14 hereof. All work referred to in this subparagraph, is hereinafter referred to as “Tenant’s Work”. Tenant shall retain its own general contractor for construction of the Tenant’s Work, which general contractor shall be subject to Landlord’s approval, as provided in Section 14 hereof and in the Work Letter. In connection with the performance of Tenant’s Work, Tenant and each of its contractors and vendors shall comply with the provisions of Section 14 (to the extent not inconsistent with the Work Letter) Subject to terms and provisions of this Lease and compliance with all terms and conditions for payment of the Allowance, if Landlord fails to pay any Tenant Allowance when the same is due, in addition to all other remedies at law or equity, Tenant shall have the right to set off such amount from Rent.

(c)Beneficial Occupancy. Tenant may access, use and occupy all or any portion of the Premises prior to the Commencement Date, for the completion of Tenant’s Work, installation of Tenant’s furniture, fixtures, and equipment, or the conduct of Tenant’s business, which such access, use, and occupancy shall be upon all of the terms and conditions set forth in this Lease (including, without limitation, the Work Letter), except that Tenant shall not be obligated to pay any Rent attributable to the Premises for any period prior to the Commencement Date hereof, provided, however, that Tenant shall reimburse Landlord for the Electricity Rate, as defined below, and for any services Landlord provides in response to Tenant’s request for such services including, but not limited to, any janitorial, cleaning or other Building services at the Premises if such services are requested by Tenant.

(d)Additional Landlord Obligations. Prior to the Commencement Date, and simultaneously in conjunction with Tenant’s Work, Landlord shall complete the Landlord’s Work and Landlord Turnover Obligations. Landlord shall be permitted access to the Premises to perform the Landlord’s Work and Landlord Turnover Obligations upon reasonable prior written notice to Tenant and shall use commercially reasonable efforts to minimize any disruption to the performance of Tenant’s Work and to reasonably cooperate with Tenant’s contractor(s) that are performing Tenant’s Work, subject to the requirements of Section 8(g). Notwithstanding anything to the contrary contained herein, if Landlord does not complete the Landlord’s Work and Landlord Turnover Obligations prior to the Commencement Date for any reason, then Tenant will receive a day-for-day abatement of Rent (to be applied to Tenant’s payments of Rent following expiration of Rent Abatement Period) for each day beyond the Commencement Date that Landlord’s Work or Landlord’s Turnover Obligations continues. Tenant shall notify Landlord of any patent or latent defects to the Landlord Turnover Obligations or Landlord’s Work within one (1) year of the Possession Date and upon receipt of any such notice, Landlord shall cure such patent or latent defect within a reasonable period of time.

(b)Electricity. Electricity for the Premises and Tenant’s lights, outlets and incidental uses shall be billed separately to the Tenant as Additional Rent, at a rate of $1.25 per square foot of Rentable Area of the Premises, per year and billed monthly (“Electricity Rate”).

In the event Landlord separately meters or submeters the Premises, then Landlord shall be responsible for any meter or sub-meter installation costs in connection with the Premises. Tenant shall make no alterations or additions to the electric equipment or systems in the Premises or the Building without the prior written consent of Landlord in each instance. Tenant also agrees to purchase from Landlord or its agents, as Landlord shall direct, all lamps, bulbs, ballasts and starters used in the Premises during the Term at commercially reasonable prices.

(c)Telecommunications.

(i)Telecommunication Services. Tenant and its telecommunications companies, including local exchange telecommunications companies and alternative access vendor services companies, shall have no right of access to and within the Building or any other portion of the Project, for the installation and operation of telecommunications systems, including voice, video, data, Internet, Wi-Fi, and any other services provided over wire, fiber optic, microwave, wireless, and any other transmission systems (“Telecommunications Services”), for part or all of Tenant’s telecommunications within the Building and from the Building to any other location without Landlord’s prior consent, which consent shall not be unreasonably withheld, conditioned or delayed, but subject to the terms of this Lease and prior execution and delivery of an access agreement on Landlord’s standard form. Landlord may restrict and control access to telephone cabinets and rooms and Building systems and risers. Tenant may not use or access the Building Structure, Building systems, common area or roof of the Building for any of Tenant’s improvements for Telecommunication Services without Landlord’s prior written consent.

Tenant, at its cost and for its own account, shall be solely responsible for obtaining all Telecommunications Services.

(ii)Cable Installation. Tenant may install, maintain, replace and remove (collectively, the “ XE “Cable Work” Cable Work”) and use any communications or computer wires, cables, fibers, connections and related telecommunications equipment and/or other facilities for telecommunications (collectively, “ XE “Cable(s)” Cable(s)”) within or serving the Premises, provided: (1) Tenant shall obtain Landlord’s prior approval, which approval shall not be unreasonably withheld, delayed or conditioned, shall use an experienced, licensed and qualified contractor approved by Landlord, which approval shall not be unreasonably withheld, delayed or conditioned, and shall comply with provisions of this Lease and shall not interfere with the use of

13

any then‑existing Cables within or serving the Building; (2) an acceptable number of spare Cables and space for additional Cables shall be maintained for existing and future occupants of the Building, as determined in Landlord’s reasonable opinion; (3) if Tenant at any time uses any equipment that may create an electromagnetic field exceeding the normal insulation ratings of ordinary twisted pair riser cable or cause radiation higher than normal background radiation, the Cables therefor (including riser Cables) shall be appropriately insulated to prevent such excessive electromagnetic fields or radiation; (4) all Cable Work shall be performed pursuant to the standards as stated in Exhibit I attached hereto. Tenant will be responsible for and will pay all costs incurred in connection with the installation of Tenant’s Cables and related wiring in the Premises, including, without limitation, any hook-up, access and maintenance fees charged by third parties and related to the installation of such wires and cables in the Premises and the commencement of service therein, and for the maintenance thereafter of such Cable Work and such wire and cables. If Tenant fails to maintain all Cables and related wiring and infrastructure in the Premises or Building and such failure adversely affects or interferes with the operation or maintenance of any other telecommunication cables or related wiring in the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises, after reasonable prior notice (except in the case of an emergency when no notice will be required) and perform such repairs, restorations or alterations as Landlord reasonably deems necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s reasonable out-of-pocket costs in connection therewith.)

Landlord shall have the right, however, upon written notice to Tenant given no later than thirty (30) days prior to the expiration or earlier termination of the Term, to require Tenant to abandon and leave in place, without additional payment to Tenant or credit against Rent, any or all of Tenant’s Cables and related infrastructure, or select components thereof, whether located in the Premises or elsewhere in the Project. Tenant shall not, without the prior consent of Landlord in each instance (which may be withheld in Landlord’s sole discretion), grant to any third party a security interest in, or lien on, any Cables, and any such security interest or lien granted without Landlord’s consent shall be null and void. This Section 8(c) is solely for Tenant’s benefit, and no one else shall be considered a third party beneficiary of these provisions.

(d)Extra or Additional Services. Tenant may request Landlord (and/or Landlord’s property manager) to provide services which are extra or additional services to those described in Section 8(a), by delivery to Landlord of an advance written request therefor. If Landlord or its property manager, at either such party’s discretion, shall agree to so provide any such services which are extra or in addition to those services described in Section 8(a), Tenant shall pay for any such extra or additional services so provided by Landlord or its property manager at Landlord’s or its property manager’s then-current established rates therefor from time to time, or if there are no established rates, the current after-hours HVAC charges as of the date of this Lease being $100.00 per hour, provided, however, such charges are subject to change from time to time. All charges for any such extra or additional services so provided by Landlord or its property manager shall be due and payable within thirty (30) days after Tenant receives Landlord’s (or Landlord’s property manager’s) bill therefor, or in installments as may be designated by Landlord (and/or Landlord’s property manager, if applicable) to Tenant in writing. If Tenant fails to pay when due Landlord’s (or

14

Landlord’s property manager’s) proper charges for any such extra or additional services, Landlord (and/or Landlord’s property manager, if applicable) shall have the right, in addition to all other rights and remedies available to such party, to discontinue furnishing any such extra or additional services for which Tenant has failed to pay. If Landlord (and/or Landlord’s property manager, if applicable) discontinues any such extra or additional services as provided in this Section 8(d), no such discontinuance shall be deemed an eviction or disturbance of Tenant’s use of the Premises or render Landlord or Landlord’s property manager liable for damages or relieve Tenant from performance of Tenant’s obligations under this Lease.

(e)Holidays. For purposes of this Section 8, “Holidays” means New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day Christmas Day, Martin Luther King, Jr. Day and any other day recognized as a holiday designated by the federal government from time to time when most non-military federal government employees are not required to work..

(f)Interruption of Services. Tenant agrees that neither Landlord, nor any of Landlord’s constituent members, shareholders, officers, or directors, nor any of their respective agents, partners or employees (including, without limitation, Landlord’s property manager), shall be liable for damage or injury to person, property or business or for loss or interruption of business, or for any other matter, in the event there is any failure, delay, interruption or diminution in furnishing any service, or in the event there is any other interruption or interference with the Tenant’s ability to conduct business in the Premises on account of Landlord entry to the Premises to perform any work as permitted hereunder, including but not limited to, such work pursuant to Sections 8(g), 9(c), and 13 below. No such failure, delay, interruption or diminution shall be deemed to constitute an eviction or disturbance of Tenant’s use or possession of the Premises, in whole or in part, actual or constructive, nor entitle Tenant to any claim for set-off, abatement or reduction of Rent, nor render Landlord or Landlord’s property manager liable for damages, nor relieve Tenant from the performance of or affect any of Tenant’s obligations under this Lease. Landlord shall use commercially reasonable efforts to minimize any such failure, delay, interruption or diminution. Notwithstanding the foregoing, in the event that there is an interruption to any service Landlord is to provide under this Lease, and such interruption continues for three (3) consecutive business days, then Rent shall abate from the fourth (4th) consecutive business day of such interruption until such service is restored.

(g)Tenant's Cooperation. Tenant agrees to reasonably cooperate fully with Landlord, at all times, in abiding by all regulations and requirements which Landlord may prescribe for the proper functioning and protection of all utilities and services reasonably necessary for the operation of the Premises or the Project Landlord and its contractors shall have free access to any and all mechanical installations in the Premises, and Tenant agrees that there shall be no construction of partitions or other obstructions which might interfere with the moving of the servicing equipment of Landlord to or from the enclosures containing said installations; provided, however, that, except in the case of an emergency and except in the case of entry in connection with the provision of routine services to be performed by Landlord hereunder, Landlord shall give Tenant twenty-four (24) hours’ prior written notice of entry to the Premises for such purpose, and at all times during any such entry Landlord will use reasonable efforts to minimize unreasonable interference with the conduct of Tenant’s business, and provided that Tenant shall have the right to have a representative present during any such entry (except in case of emergency). Tenant further agrees that neither Tenant nor its employees, agents, licensees, invitees or contractors shall at any time tamper with, adjust or otherwise in any manner adversely affect Landlord’s mechanical installations in the Premises or the Project.

(h)Supplemental Heating or Cooling. Whenever, in Landlord’s reasonable judgment, Tenant’s use or occupation of the Premises, including lighting, personnel, heat generating machines or equipment, or airborne emissions of smoke or other particulates, individually or cumulatively, causes the design loads for the system providing heat and air-cooling to be exceeded, or otherwise adversely affects the temperature, humidity or air quality otherwise maintained by the heating, ventilating and air handling or conditioning

15

system in the Premises or the Building, then, after Landlord has first provided Tenant with a reasonable period of advance notice (and, in any event, at least fifteen (15) days’ notice) to cure such condition (provided that no such notice or cure period shall be required in the case of an emergency), Landlord and/or Landlord’s property manager may, but shall not be obligated to, temper such excess loads by installing supplementary heating or air handling or conditioning units in the Premises or elsewhere where necessary. In such event, the cost of such units and the expense of installation, including, without limitation, the cost of preparing working drawings and specifications, plus five percent (5%) of such cost as an overhead and supervision fee, shall be paid by Tenant to Landlord or Landlord’s property manager (as the case may be) within ten (10) days after such party’s written demand therefor. Alternatively, Landlord may require Tenant to install such supplementary heating or air handling or conditioning units at Tenant’s sole expense. Landlord may operate and maintain any such supplementary units, but shall have no continuing obligation to do so or liability in connection therewith. The expense resulting from the operation and maintenance of any such supplementary heating or air handling or conditioning units, including utility charges, charges for condenser water, repair costs, labor costs and rent for space occupied by any supplementary heating or air handling or conditioning units installed in Rentable Area outside the Premises, shall be paid by Tenant to Landlord or Landlord’s property manager at rates fixed by such party. Alternatively, Landlord may require Tenant to operate and maintain any such supplementary units, also at Tenant’s sole expense. Landlord acknowledges that Tenant anticipates installing the Tenant Supplemental HVAC, as defined below. Subject to Section 14, in the event that Tenant obtains approval from Landlord to install supplemental heating and cooling equipment in the Premises (as provided in Section 14 or in the Work Letter), which approval, in either case, shall not be unreasonably withheld, conditioned or delayed (the “Tenant Supplemental HVAC”), and Tenant provides written notice to Landlord that it desires that the Supplemental HVAC be separately metered, or sub-metered, as applicable, then Landlord agrees to use commercially reasonable efforts to accomplish the same, provided, all (i) metering and sub-metering, as applicable, and (ii) installation of the Tenant Supplemental HVAC, are each at Tenant’s sole cost and expense.

(i)Access. Tenant and its employees shall have access to the Premises twenty-four (24) hours per day, seven (7) days per week, subject to Rules and Regulations, matters of the kinds referred to in Section 28(j) hereof, and orders of governmental authorities.

Landlord shall not be liable in damages or otherwise for any error with respect to admission to or eviction or exclusion from the Project or any part thereof of any person. Notwithstanding anything contained herein to the contrary, in case of fire, casualty, invasion, insurrection, mob, riot, act of terrorism, act(s) of god, declared state of emergency, civil disorder, public excitement or other commotion, or threat thereof, Landlord reserves the right to limit or prevent access to the Project or any part thereof during the continuance of the same, halt elevator service, activate elevator emergency controls, or otherwise take such action or preventive measures reasonably deemed necessary by Landlord for the safety or security of the tenants or other occupants of the Project or the protection of the Project and the property in or about the Project. Tenant agrees to cooperate in any reasonable safety or security program developed by Landlord from time to time.

(h)To control, restrict and prevent access to any areas of the Project, provided that reasonable access to the Premises, common areas and parking areas shall be maintained.

(i)To rearrange, relocate, enlarge, reduce or change corridors, exits, elevators, stairs, lavatories, doors, entrances in or to the Building, and to decorate and to make repairs, alterations, additions and improvements, structural or otherwise, in or to the Land or the Project or any part thereof, including the Premises, and any adjacent building, land, street or alley, including for the purpose of connection with or entrance into or use of the Land or the Project in conjunction with any adjoining or adjacent building or buildings or pedestrian ways, now existing or hereafter constructed, provided that Landlord maintains reasonable access to the Premises, common areas and parking areas and minimizes interference with the conduct of Tenant’s business and provided that Tenant is still able to use the Premises for the intended purpose and utilize its other rights granted hereunder (e.g., parking rights). In that regard, Landlord may erect scaffolding and other structures reasonably required by the character of the work to be performed, and during such operations to enter upon the Premises upon reasonable prior notice (which may be oral notice) and take into and upon or through any part of the Project, excluding the Premises (unless reasonably

21

required, and in such event, Landlord shall provide a minimum of forty-eight hours advanced notice to Tenant), all materials that may be required to do such work or make such decorations, repairs, alterations, improvements or additions, and in connection with any of the foregoing, to temporarily close public entryways, other public spaces, stairways or corridors and interrupt or temporarily suspend any services or facilities agreed to be furnished by Landlord. Except in the case of an emergency(ies), Landlord shall use commercially reasonable efforts to (i) minimize any access to the Premises during ordinary bustiness hours and (ii) endeavor to make any such decorations, repairs, alterations, improvements and additions in the Premises outside of ordinary business hours. Landlord may, at its option, do any such work and make any such decorations, repairs, alterations, improvements and additions in and about the Project during ordinary business hours and, if Tenant desires to have the same done during other than ordinary business hours, Tenant shall pay all overtime and additional expenses resulting therefrom.

(j)To establish controls for the purpose of regulating all property and packages to be taken into or removed from the Building and Premises.

(k)To regulate delivery of supplies and services in order to ensure the cleanliness and security of the Project and to avoid congestion of the loading docks, receiving areas and freight elevators.

(m)To show the Premises to prospective tenants at reasonable hours during the last twelve (12) months of the Term or to prospective mortgagees, ground lessors or purchasers of the Land or Building or both upon at least twenty-four (24) hours’ notice to Tenant (and Tenant shall have the right to have a Tenant representative present) and, if vacated or abandoned, to show the Premises to prospective tenants at any time and to demolish, alter, remodel or otherwise prepare the Premises for re-occupancy.

(n)To erect, use and maintain concealed pipes, ducts, wiring and conduits, and appurtenances thereto, in and through the Premises, in walls, below the floor and above the suspended ceiling.

(o)From time to time to amend the Rules and Regulations for the use, entry, operation or management of the Premises or the Project or for the protection or welfare of the Project or its tenants or occupants, or any property therein, as Landlord may reasonably determine, and Tenant agrees to accept, abide by and comply such reasonable amendments to the Rules and Regulations of which Tenant has received written notice. If any such rules and regulations conflict with any rights expressly granted to Tenant under the terms and provisions of this Lease, the terms and provisions of this Lease shall control.

(p)To designate and/or approve, prior to installation, all types of window shades, blinds, drapes, awnings or other similar items, and all internal lighting that may be visible from the exterior of the Premises.

14.ALTERATIONS.

(a)Consent; Conditions. Except for the Permitted Alterations, as hereinafter defined, Tenant shall not perform any Tenant Alterations without first obtaining the prior written consent of Landlord, which shall not unreasonably be withheld, conditioned, or delayed. Without limitation on the foregoing, Landlord may impose such conditions with respect to Tenant Alterations as Landlord deems appropriate, including, without limitation, requiring Tenant to furnish to Landlord for its approval prior to commencement of any work or entry by Tenant’s contractors into the Premises or the Building, security for the payment of all costs to be incurred in connection with any such Tenant Alterations, insurance against liabilities which may arise out of the Tenant Alterations, and plans and specifications and permits necessary for the Tenant Alterations.

(b)Permitted Alterations. Tenant shall have the right at any time during the Term, without needing Landlord's prior written consent, to make cosmetic, non‑material and non‑structural alterations to the Premises which cost shall not exceed Twenty-Five Thousand Dollars ($25,000) in any one calendar year (the “Permitted Alterations”). Tenant shall provide advanced written notice to Landlord of any Permitted Alterations no later than thirty (30) days before making any Permitted Alterations. Notwithstanding the foregoing, Tenant shall make no Alterations to the Premises (i) which will adversely impact the Building's mechanical, electrical or heating, ventilation or air conditioning systems, or (ii) which will adversely impact the structure of the Building, or (iii) which are visible from the exterior of the Premises or (iv) which will result in the penetration or puncturing of the roof or floor, without first obtaining Landlord's prior written consent or approval to such Alterations, not to be unreasonably withheld, conditioned or delayed).

(c)Contractors. Tenant Alterations shall be done at Tenant’s expense by agents or contractors hired by Tenant who are reasonably acceptable to Landlord and whose work will not cause or threaten to cause disharmony or interference with Landlord or other tenants, contractors or service providers at the Building, or at Landlord’s election, by Landlord’s employees or contractors hired by Landlord. Before employing any such contractors, Tenant shall submit to Landlord the names and addresses of such contractors.

(d)Costs; Mechanic Liens. Tenant shall promptly pay the cost, when due, of all Tenant Alterations. In addition to the cost of such Tenant Alterations, Tenant shall also pay to Landlord or to Landlord’s property manager or other designated agents, as Landlord shall direct, an amount equal to seven percent (7%) of all of the costs of all Tenant Alterations that are not cosmetic, as a coordination and management fee allocable to the Tenant Alterations. Upon completion of any Tenant Alterations, Tenant shall deliver to Landlord, if payment is made directly to contractors, evidence of payment, contractors’ affidavits and full and final waivers of all liens for labor, services and materials sufficient to waive all rights to liens under the Illinois Mechanic’s Lien law arising from the work done. Tenant shall not permit any lien or claim for lien of any mechanic, labor or supplier or any other lien to be filed against the Building, the Land or the Premises or any part thereof, arising out of any Tenant Alterations or other work performed or alleged to be performed, by or at the direction of Tenant. If any such lien or claim for lien is filed, Tenant shall, within ten (10) days of receiving notice of such lien or claim, (i) have such lien or claim for lien released of record, or (ii) deliver to Landlord a bond or other security in form, content, and amount satisfactory to Landlord relative to such lien or claim for lien (whereupon, in the case of this subclause (ii), Tenant shall thereafter diligently contest such lien or claim for lien). Without limitation of the foregoing, Tenant shall indemnify, defend and hold harmless Landlord and the Landlord Parties from and against any such lien or claim for lien, and the foreclosure or attempted foreclosure thereof, and Tenant shall cause any such lien to be released of record, in any event, prior to final enforcement thereof. If Tenant fails to take the actions described in subclause (i) or subclause (ii) above, then Landlord or Landlord’s property manager, without investigating the validity of such lien or claim for lien, may pay or discharge the same,

23

and Tenant shall, as payment required therefor hereunder, reimburse Landlord or Landlord’s property manager promptly upon written demand for the payment so made by Landlord or Landlord’s property manager, including Landlord’s or Landlord’s property manager’s expenses and attorneys’ fees related thereto.

(e)General. Tenant agrees to indemnify, defend by counsel reasonably acceptable to Landlord and hold Landlord and the other Landlord Parties, and the Project, harmless of, from and against any and all losses, damages, liabilities, claims, liens, costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses, arising in connection with any Tenant Alterations. All Tenant Alterations done by Tenant or its contractors, including work done pursuant to Section 9, shall be performed in a first-class, workmanlike manner using only good grades of materials and shall comply with all insurance requirements of Landlord and all Laws. Within thirty (30) days after substantial completion of any Tenant Alterations (except Permitted Alterations) by or on behalf of Tenant, to the extent available, Tenant shall furnish to Landlord, in both electronic form and in hard copy, “as built” drawings of such Tenant Alterations. All Tenant Alterations shall be performed in accordance with Construction Rules (as hereinafter defined). In no event shall any supervision or right to supervise by Landlord, nor shall any approvals given by Landlord hereunder, constitute any warranty by Landlord to Tenant of the adequacy of the design, workmanship or quality of the Tenant Alterations, or impose any liability upon Landlord in connection with the performance of such work.

15.ASSIGNMENT AND SUBLETTING.

(a)Prohibitions. Subject to a Permitted Transfer as provided in Section 15(i), Tenant shall not, either prior or subsequent to the commencement of the Term, (i) assign, transfer, mortgage, pledge, hypothecate or encumber or subject to or permit to exist upon or be subjected to any lien or charge, this Lease or any interest under it, (ii) allow to exist or occur any transfer of or lien upon this Lease or Tenant’s interest herein by operation of law, (iii) sublet the Premises or any part thereof, or (iv) permit the use or occupancy of the Premises or any part thereof for any purpose not provided for under Section 6 of this Lease or by anyone other than Tenant and Tenant’s employees, without first obtaining Landlord’s prior written consent in accordance with this Section 15. Subject to a Permitted Transfer as provided in Section 15(i) and the terms of this Section 15, Landlord’s consent to any assignment or subletting shall not be unreasonably withheld, conditioned, or delayed. In no event shall this Lease be assigned or assignable by voluntary or involuntary bankruptcy proceedings or otherwise, except as provided by law, and in no event shall this Lease or any rights or privileges hereunder be an asset of Tenant under any bankruptcy, insolvency or reorganization proceedings, except as provided by law. Any of the foregoing performed or attempted in violation of the provisions of this Section shall be null and void.

(b)Continuing Liability. No assignment, subletting, use, occupancy, transfer or encumbrance by Tenant shall operate to relieve Tenant from any covenant, liability or obligation under this Lease except to the extent, if any, expressly provided for in any such written consent of Landlord to the foregoing, and none of the foregoing, and no consent to any of the foregoing, shall be deemed to be a consent to or relieve Tenant from obtaining Landlord’s consent to any subsequent assignment, subletting, use, occupancy, transfer or encumbrance. Tenant shall pay all reasonable costs, charges and expenses incurred by Landlord or Landlord’s property manager, including, without limitation, reasonable attorneys’ fees and expenses, incurred in connection with any assignment, subletting, use, occupancy, transfer or encumbrance made or requested by Tenant.

(c)Notice of Proposed Assignment or Sublease. Tenant shall, by notice in writing, advise Landlord of its intention from, on and after a stated date (which shall not be less than thirty (30) nor more than one hundred eighty (180) days after the date of the giving of Tenant’s notice to Landlord) to assign this Lease or sublet all or any part of the Premises for the balance or any part of the Term. Tenant’s notice

24

shall include the name and address of the proposed assignee or subtenant, a true and complete copy of the proposed assignment or sublease and sufficient information, as Landlord deems reasonably necessary, to permit Landlord to determine (i) the financial responsibility and character and the nature of the business of the proposed assignee or subtenant, and (ii) whether Landlord has the right under this Lease to withhold consent to the proposed assignment or sublease.

(d)Grounds for Withholding Consent. Landlord will not unreasonably withhold or delay its consent to Tenant’s assignment of this Lease or subletting the space covered by Tenant’s notice. Landlord shall not be deemed to have unreasonably withheld its consent to a proposed assignment of this Lease or to a proposed sublease of part or all of the Premises if its consent is withheld because: (i) Tenant is then in Default under this Lease; (ii) any notice of termination of this Lease or termination of Tenant’s right of possession has been given under Section 19; (iii) either the portion of the Premises which Tenant proposes to sublease, or the remaining portion of the Premises, or the means of ingress or egress to either the portion of the Premises which Tenant proposes to sublease or the remaining portion of the Premises is of such nature that it will violate any applicable Laws, is of such accessibility, size or irregular shape so as not to be suitable for normal renting purposes as space on a multi-tenant floor within the Building; (iv) the proposed use of the Premises by the proposed assignee or subtenant is not permitted by the terms of this Lease, or will violate any applicable Laws, will impose any obligation upon Landlord or materially increase Landlord’s obligations under or cost of compliance with any Laws, or will violate any exclusive right Landlord has granted or contemplates granting in the future to any tenant of any part of the Project; (v) in the reasonable judgment of Landlord the proposed assignee or subtenant is of a character or is engaged in a business which would be deleterious to the reputation of the Project, Landlord or any of the constituent members of Landlord; (vi) in the reasonable judgment of Landlord, the proposed assignee or subtenant is not sufficiently financially responsible to perform its obligations under the proposed assignment or sublease; (vii) the proposed assignee or subtenant is a government (or subdivision or agency thereof); or (viii) the proposed assignee or subtenant is an occupant (or affiliate thereof) of the Building or is a person or entity (or affiliate thereof) Landlord is then dealing with or has dealt with during the prior nine (9) months with regard to leasing of space in the Building; provided, however, that the foregoing are merely examples of reasons for which Landlord may withhold its consent and shall not be deemed exclusive of any permitted reasons for reasonably withholding consent, whether similar or dissimilar to the foregoing examples, and Landlord may consider all relevant reasonable factors in determining whether to give or withhold its consent. Tenant agrees that all advertising by Tenant or on Tenant’s behalf with respect to the assignment of this Lease or subletting of any part of the Premises must be reasonably approved in writing by Landlord prior to publication.

(e)Excess Rent Payment. If Tenant (as Tenant or debtor-in-possession) shall assign this Lease or sublet the Premises, or any part thereof, at a rental or for other consideration in excess of the Rent or pro rata portion thereof due and payable by Tenant under this Lease after deducting any reasonable third-party costs associated with such assignment or sublease, including but not limited to any tenant improvements, allowances, reasonable attorneys’ fees, commissions, rent abatement, etc., then Tenant shall pay to Landlord as additional Rent fifty percent (50%) of any such excess rent or other consideration promptly upon receipt under any such assignment or, in the case of a sublease, on the later of the first day of each month during the term of any sublease, or the day of receipt from such subtenant, fifty percent (50%) of any such excess rent or other consideration paid by the subtenant for such month over the Rent then payable to Landlord pursuant to the provisions of this Lease for said month (or if only a portion of the Premises is being sublet, fifty percent (50%) of the excess of all rent and other consideration due from the subtenant for such month over the portion of the Rent then payable to Landlord pursuant to the provisions of this Lease for said month which is allocable on a Rentable Area basis to the space sublet). Landlord shall not be responsible for any deficiency if Tenant shall assign this Lease or sublet the Premises or any part thereof at a rental less than that provided for herein.

25

(f)Lease Assumption; Subtenant Attornment. If Tenant assigns this Lease, the assignee shall expressly assume all of the obligations of Tenant hereunder in a written instrument provided by or approved by Landlord and delivered to Landlord not later than ten (10) days prior to the effective date of the assignment. If Tenant subleases any part of the Premises, Tenant shall obtain and furnish to Landlord, not later than ten (10) days prior to the effective date of such sublease and in form reasonably satisfactory to Landlord, the written agreement of such subtenant to the effect that the subtenant will attorn to Landlord, at Landlord’s option and written request (at Landlord’s sole election), if this Lease terminates before the expiration of the sublease. Tenant shall, not later than fifteen (15) days after the effective date of any such assignment or sublease, deliver to Landlord a certified copy of the instrument of assignment or sublease.

(g)Intentionally Omitted.

(h)Re-Affirmation of Representations. By assuming this Lease, any assignee shall affirm to Landlord in writing the representations contained in Sections 28(t) (UBIT), and 28(u) (Anti-Money Laundering/International Trade Law Compliance) of this Lease as of the date of such assumption, and Tenant agrees that it shall incorporate the requirements of such sections of the lease in any document assigning the lease. Prior to the effectiveness of any sublease hereunder, Tenant shall obtain and deliver to Landlord an affirmation of the representations contained in Sections 28(t) (UBIT), and 28(u) (Anti-Money Laundering/International Trade Law Compliance) of this Lease as applicable to the subtenant.

(i)Permitted Transfers. Notwithstanding any of the foregoing, Landlord’s consent shall not be required for an assignment or sublet to a Tenant Affiliate (as hereinafter defined), or for any transaction or transactions resulting in the transfer of control of Tenant, as long as (i) Tenant gives reasonable prior written notice to Landlord of the assignment or sublet; (ii) if an assignment, such assignee assumes the obligations of Tenant under this lease; and (iii) if an assignment, in the reasonable judgment of Landlord, the assignee has a net worth of not less than the net worth of the original named Tenant as of the date of this lease and the assignee is otherwise sufficiently financially responsible to perform its obligations under this lease. Tenant will provide Landlord with notice of any transfer of control of Tenant within fifteen (15) days of such change of control occurring. As used herein, the term “Tenant Affiliate” shall mean any entity (x) which acquires all or substantially all of the direct or indirect voting equity or the assets of the original Tenant under this Lease for a purpose other than to circumvent the provisions of this Section 15; (y) which is controlled by, controls, or is under common control with, Tenant under this lease; or (z) which results from a merger, consolidation or reorganization of or with Tenant under this lease. Except as provided in this Section 15(i), all terms of this Section 15 shall apply with respect to an assignment or sublet to a Tenant Affiliate (including, without limitation, the terms of Section 15(b) regarding the continued liability of the “Tenant” making such assignment or sublease, as well as the continued liability of each prior “Tenant”).

16.WAIVER OF CERTAIN CLAIMS, INDEMNITY.

(a)General Waiver. In addition to and without limiting or being limited by any other releases or waivers of claims in this Lease, but rather in confirmation and furtherance thereof, to the extent not prohibited by law, Landlord and Tenant each releases and waives any and all claims for, and rights to recover, damages against and from the other, and the other’s respective agents, members, partners, shareholders, officers and employees (collectively, the “Released Parties”), for loss, damage or destruction to any of its property (including the Premises, the Building and their contents), the elements of which are insured against or which would have been insured against had such party suffering such loss, damage or destruction maintained the property or physical damage insurance policies required under Section 22 hereof. In no event shall this clause be deemed, construed or asserted (i) to affect or limit any claims or rights against any Released Parties other than the right to recover damages for loss, damage or destruction to property, or (ii) to benefit any third party other than the Released Parties.

26

(b)Indemnity. In addition to and without limiting or being limited by any other indemnity in this Lease, but rather in confirmation and furtherance thereof, to the extent not prohibited by applicable Laws, and unless arising from Landlord’s gross negligence or willful misconduct, Tenant agrees to indemnify, defend by counsel reasonably acceptable to Landlord and hold Landlord and the Landlord Parties, and the Project, harmless of, from and against any and all losses, damages, liabilities, actions, demands, claims, liens, costs and expenses, including court costs and reasonable attorneys’ fees and expenses, in connection with injury to or death of any person or with respect to damage to or theft, loss or loss of the use of any property, occurring in or about the Premises or the Project and arising from Tenant’s occupancy of the Premises, or the conduct of its business or from any activity, work, or thing done, permitted or suffered by Tenant in or about the Premises or the Project, or from any breach or default on the part of Tenant in the performance of any covenant or agreement on the part of Tenant to be performed pursuant to the terms of this Lease, or due to any negligent act or omission or willful misconduct of Tenant, or any of its employees, agents, licensees, invitees or contractors.

(c)Waiver. To the extent permitted by law, Tenant releases Landlord and the Landlord Parties from, and waives all claims for, damage or injury to person or property sustained by the Tenant or any occupant of the Building or Premises resulting directly or indirectly from any existing or future condition, defect, matter or thing in and about the Project or the Premises or any part of either or any equipment or appurtenance therein, or resulting from any accident in or about the Project or resulting directly or indirectly from any act or neglect of any tenant or occupant of the Building or of any other person, including Landlord’s agents and servants, except where resulting from the neglect or willful act of Landlord or any of the Landlord Parties. Each of Landlord and Tenant hereby waives any consequential damages, compensation or claims for inconvenience or loss of business, rents, or profits as a result of any injury or damage occurring at or about the Building or arising under this Lease.

(d)Landlord’s Negligence. No agreement of Tenant in this Lease shall be deemed to exempt Landlord from liability or damages for injury to persons caused by or resulting from the gross negligence or willful misconduct of Landlord, its agents, servants or employees, in the operation or maintenance of the Premises or Building.

17.DAMAGE OR DESTRUCTION BY CASUALTY.

(a)Termination of Lease; Repair by Landlord. If the Premises or the Building is damaged by fire or other casualty, and if such damage does not render all or a substantial portion of the Premises or the Building untenantable, then Landlord shall proceed with reasonable promptness to repair and restore the core and shell of the Building and the Premises so as to render the Premises tenantable, subject to reasonable delays for insurance adjustments and delays caused by matters beyond Landlord’s reasonable control, and also subject to zoning Laws and building codes then in effect. If any such damage renders all or a substantial portion of the Premises or the Building untenantable, Landlord shall, with reasonable promptness after the occurrence of such damage, estimate the length of time that will be required to substantially complete the repair and restoration of the core and shell of the Building and the Premises, as the case may be, necessitated by such damage and shall by notice advise Tenant of such estimate. If it is so estimated that the amount of time required to substantially complete such repair and restoration will exceed two hundred seventy (270) days from the date such damage occurred, then either Landlord or Tenant (but Tenant shall have such right only if the damage was not caused by the gross neglect or willful act of Tenant, its agents, employees, contractors, or invitees, and only if all or a substantial portion of the Premises is rendered untenantable and the estimated time required for Landlord to substantially complete such repair or restoration to render the Premises tenantable will exceed such two hundred seventy (270) day period) shall have the right to terminate this Lease as of the date of notice of such election by giving notice to the other at any time within twenty (20) days after Landlord gives Tenant the notice containing said estimate (it being understood that Landlord may, if it elects to do so, also give such notice of termination together with the notice containing

27

said estimate). Unless this Lease is terminated as provided in the preceding sentence, Landlord shall proceed with reasonable promptness to repair and restore the core and shell of the Building or the Premises so as to render the Premises tenantable, subject to reasonable delays for insurance adjustments and delays caused by matters beyond Landlord’s reasonable control, and also subject to zoning Laws and building codes then in effect. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease (except as hereinafter provided) if such repairs and restoration are not in fact completed within the time period estimated by Landlord, as aforesaid, or within said two hundred seventy (270) days. However, if such repairs and restoration are not completed by a date (“Outside Date”) which is twelve (12) months after the date of such fire or other casualty (or ninety-five (95) days after the expiration of the time period estimated by Landlord as aforesaid, if longer than two hundred seventy (270) days and neither party terminated the lease as permitted), which Outside Date shall be extended (as to Tenant’s ability to terminate only) by all periods of delay attributable to the acts or omissions of Tenant or Tenant’s agents, employees or contractors, for any reason whatsoever, then either party may terminate this Lease, effective as of the date of notice of such election, by giving written notice to the other party within the thirty (30) day period after said Outside Date as extended as aforesaid, but prior to substantial completion of repair or restoration (but Tenant shall again have such right only if the damage was not caused by the neglect or willful act of Tenant, its agents, employees, contractors, or invitees, and only if all or a substantial portion of the Premises was rendered untenantable). Notwithstanding anything to the contrary herein set forth: (i) Landlord shall have no duty pursuant to this Section 17 to repair or restore any portion of Tenant’s Alterations or any other improvements, additions or alterations made by or on behalf of Tenant in the Premises, including improvements performed by Landlord pursuant to this Lease and/or the Work Letter, if any; (ii) Landlord shall not be obligated (but may, at its option, so elect) to repair or restore the Premises or Building if the damage is due to an uninsurable casualty or if insurance proceeds are insufficient to pay for such repair or restoration, or if any Mortgagee applies proceeds of insurance to reduce its loan balance, and the remaining proceeds, if any, available to Landlord are not sufficient to pay for such repair or restoration; or (iii) if any such damage rendering all or substantial portion of the Premises or Building untenantable shall occur during the last year of the Term, either party (but as to Tenant’s right, only if all or a substantial portion of the Premises is rendered untenantable, and only if such damage was not caused by the neglect or willful act of Tenant, its agents, employees, contractors or invitees) shall have the option to terminate this Lease by giving written notice to the other within thirty (30) days after the date such damage occurred, and if such option is so exercised, this Lease shall terminate as of the date of such notice.

(b)Repair by Tenant. If this Lease is not terminated pursuant to this Section 17, Tenant shall, in accordance with Section 14, proceed with reasonable promptness to repair and restore all Tenant’s Alterations and all other alterations, additions and improvements in the Premises, other than any repairs or restoration required to be made by Landlord pursuant to Section 17(a) above, to as near the condition which existed prior to the fire or other casualty as is reasonably possible. Tenant agrees and acknowledges that Landlord shall be entitled to the proceeds of any insurance coverage carried by Tenant relating to improvements and betterments to the Premises, to the extent Landlord is obligated under this Section 17 to repair or restore damage to those items covered by such insurance or if this Lease terminates.

(c)Abatement of Rent. Except to the extent arising from the omissions, negligence or willful acts of Tenant or its agents, employees, contractors or invitees, in the event any such fire or casualty damage renders the Premises untenantable and if this Lease shall not be terminated pursuant to the foregoing provisions of this Section 17 by reason of such damage, then Rent shall abate during the period beginning with the date of such damage and ending with the date when Landlord substantially completes its repair or restoration required hereunder. Such abatement shall be in an amount bearing the same ratio to the total amount of Rent for such period as the portion of the Rentable Area of the Premises which is untenantable and not used by Tenant from time to time bears to the Rentable Area of the entire Premises. In the event of termination of this Lease pursuant to this Section 17, Rent shall be apportioned on a per diem basis and be paid to the date of the termination.

28

(d)Untenantability. As used in this Lease, the term “untenantable” means reasonably incapable of being occupied for its intended use due to damage to the Premises or Building. Notwithstanding anything contained to the contrary in this Section 17, neither the Premises nor any portion of the Premises shall be deemed untenantable if Landlord is not required to repair or restore same (or if Landlord is required to repair or restore same, then following such time as Landlord has substantially completed the repair and restoration work required to be performed by Landlord under this Section 17), or if Tenant continues to actually occupy the subject portion of the Premises.

(e)Core and Shell. The term “core and shell” shall include all base Building improvements at the Building or within the Premises (as the case may be), but specifically excludes any work related to tenant improvements constructed or to be constructed by or for Tenant or other tenants or installed within the Premises or within any other tenant’s premises.

18.EMINENT DOMAIN.

(a)Substantial Taking. If the entire Project or the entire Building, or a substantial part of either of them, or any part of the Project which includes all or a substantial part of the Premises or which prevent access to or use of the Premises, shall be taken or condemned by any competent authority for any public or quasi-public use or purpose, the Term of this Lease shall end upon and not before the earlier of the date when the possession of the part so taken shall be required for such use or purpose or the effective date of the taking. If any condemnation proceeding shall be instituted in which it is sought to take or damage any part of the Project, the taking or damaging of which would, in Landlord’s opinion, prevent the economical operation of the Project, or if the grade of any street or alley adjacent to the Land or the Building is changed or any such street or alley is closed by any competent authority, and such taking, damage, change of grade or closing makes it necessary or desirable to remodel the Building to conform to the taking, damage, change of grade or closing, Landlord shall have the right to terminate this Lease upon written notice to Tenant given not less than ninety (90) days prior to the date of termination designated in the notice. If any of the events described herein occurs, Rent shall be apportioned on a per diem basis and be payable to the date of the termination.

(b)Taking of Part. In the event a part of the Building or the Premises is taken or condemned by any competent authority and this Lease is not terminated as provided in Section 18(a) above, the lease shall be amended to reduce the Monthly Rent, if applicable, to reflect the Rentable Area of the Premises or Building, as the case may be, remaining after any such taking or condemnation. Landlord, upon receipt and to the extent of the award in condemnation (or proceeds of sale), shall make necessary repairs and restorations to the Premises (exclusive of any Tenant’s Alterations, or any other improvements made by or on behalf of Landlord or Tenant) and to the Building to the extent necessary to constitute the portion of the Building not so taken or condemned as a complete architectural and economically efficient unit.

(c)Compensation. Landlord shall be entitled to receive the entire award (or sale proceeds) from any such taking, condemnation or sale without any payment to Tenant, and Tenant hereby assigns to Landlord all of Tenant’s interest, if any, in such award; provided, however, Tenant shall have the right separately to pursue against the condemning authority a separate award in respect of the loss, if any, to Tenant Alterations paid for by Tenant without any credit or allowance from Landlord, so long as there is no diminution of Landlord’s award as a result, and subject to the rights of any ground lessor or mortgagee of Landlord with respect thereto.

19.DEFAULT; LANDLORD’S RIGHTS AND REMEDIES.

(a)Default. The occurrence of any one or more of the following matters constitutes a “Default” by Tenant under this Lease:

(b)Landlord's Rights and Remedies. If a Default occurs, Landlord shall have the rights and remedies hereinafter set forth, which shall be distinct, separate and cumulative and shall not operate to exclude or deprive Landlord of any other right or remedy allowed it at law or in equity:

(i)Landlord may terminate this Lease, in which event the Term of this Lease shall end, and all right, title and interest of Tenant hereunder shall expire, on the date stated in such notice;

(ii)Landlord may terminate the right of Tenant to possession of the Premises without terminating this Lease, whereupon the right of Tenant to possession of the Premises or any part thereof shall cease on the date stated in such notice;

(iii)Landlord may terminate and/or remove any Tenant signage installed, or rights of Tenant to signage at the Premises, Building and/or Project without terminating this Lease, whereupon the right(s) of Tenant to signage at the Premises, Building and/or Project or any part thereof shall cease on the date stated in such notice and Landlord may remove any Tenant signage installed;

(iv)Landlord may enforce the provisions of this Lease and may enforce and protect the rights of Landlord hereunder by a suit or suits in equity or at law for the specific performance of any covenant or agreement contained herein, and for the enforcement of any other appropriate legal or equitable remedy, including, without limitation, distraint for Rent, injunctive relief, recovery of all money due or to become due from Tenant under any of the provisions of this Lease and recovery of damages incurred by Landlord by reason of the Default; and

(v)Landlord may cure or correct such Default (or cause such cure or correction to occur) or take steps to perform (or cause to be performed) any covenant, agreement, condition or provisions of this Lease, and all costs and expenses incurred by Landlord, or Landlord’s property manager or other designated representative, in so doing (including reasonable attorneys’ fees), shall be paid by Tenant to such party upon written demand plus interest at the Default Rate from the date of expenditure. Landlord’s proceeding under the rights reserved to Landlord under this Section 19(b)(v) shall not in any way prejudice or waive any rights as Landlord might otherwise have against Tenant by reason of that or any other Default.

(c)Surrender. If Landlord exercises any of the remedies provided for in subparagraphs (i) and (ii) of Section 19(b), Tenant shall surrender possession of and vacate the Premises and immediately deliver possession thereof to Landlord, and Landlord may re-enter and take complete and peaceful possession of the Premises, with (if Tenant is in occupancy of the Premises) process of law.

(d)Termination of Right of Possession. If Landlord terminates the right of Tenant to possession of the Premises without terminating this Lease, as provided for by subparagraph (ii) of Section 19(b), then Landlord shall be entitled to recover from Tenant all the fixed dollar amounts of Rent accrued and unpaid for the period up to and including such termination date, as well as all other additional sums payable by Tenant, or for which Tenant is liable or in respect of which Tenant has agreed to indemnify Landlord under any of the provisions of this Lease, which may be then owing and unpaid, and all costs and expenses, including, without limitation, court costs and reasonable attorneys’ fees and expenses incurred by Landlord in the enforcement of its rights and remedies hereunder, and in addition, Landlord shall be entitled to recover from Tenant from time to time, and Tenant shall remain liable for, all Rent and all other additional sums thereafter accruing as they become due under this Lease during the period from the date of such notice of termination of possession to the stated end of the Term. In any such case, Landlord shall use reasonable efforts as required by applicable Laws to relet the Premises for the account of Tenant for such Rent, for such time (which may be for a term extending beyond the Term of this Lease), in such portions and upon such terms as Landlord in Landlord’s sole discretion shall determine, and Landlord shall not be required to

31

accept any tenant offered by Tenant or to observe any instructions given by Tenant relative to such reletting. Landlord may give priority over leasing the Premises to any other space Landlord desires to lease in the Building and shall not be required in any case to offer rent, length of terms or other terms for the Premises which are or would be less favorable to Landlord than being offered for comparable space of Landlord in the Building. Also, in any such case, Landlord may make (or cause to be made) repairs, alterations and additions in or to the Premises and redecorate (or cause to be redecorated) the same to the extent deemed by Landlord necessary or desirable, and in connection therewith Landlord may change (or cause to be changed) the locks to the Premises, and Tenant shall upon written demand pay the cost thereof together with the expenses of reletting incurred by Landlord, its property manager or other designated agent. Landlord may collect the rents from any such reletting and shall apply the same first to the payment of the expenses of reentry, redecoration, repair, alterations and reletting and second to the payment of Rent herein provided to be paid by Tenant, and any excess or residue shall operate only as an offsetting credit against the amount of Rent, if any, due and owing or as the same thereafter becomes due and payable hereunder, but the use of such offsetting credit to reduce the amount of Rent due Landlord, if any, shall not be deemed to give Tenant any right, title or interest in or to such excess or residue, and any such excess or residue shall belong to Landlord solely; provided that in no event shall Tenant be entitled to such a credit against Rent in excess of the aggregate sum (including Monthly Rent and Additional Rent) which would have been paid by Tenant for the period for which the credit to Tenant is being determined had no Default occurred. No such re-entry, repossession, repairs, alterations, additions or reletting shall be construed as an eviction or ouster of Tenant or as an election on Landlord’s part to terminate this Lease, unless a written notice of such intention is given to Tenant, or shall operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, and Landlord may, at any time and from time to time, sue and recover judgment for any deficiencies from time to time remaining after the application from time to time of the proceeds of any such reletting.

(e)Termination of Lease. In the event of the termination of this Lease by Landlord as provided for by subparagraph (i) of Section 19(b), Landlord shall be entitled to recover from Tenant all the fixed dollar amounts of Rent accrued and unpaid for the period up to and including such termination date, as well as all other additional sums payable by Tenant, or for which Tenant is liable or in respect of which Tenant has agreed to indemnify Landlord under any of the provisions of this Lease, which may be then owing and unpaid, and all costs and expenses, including, without limitation, court costs and reasonable attorneys’ fees and expenses incurred by Landlord in the enforcement of its rights and remedies hereunder, and in addition, Landlord shall be entitled to recover an amount equal to the present value (calculated using a discount rate equal to six percent (6%) per annum) of the aggregate Monthly Rent and Additional Rent payable for the period from the termination date stated in Landlord’s notice terminating this Lease until the date which would have been the Expiration Date but for such termination, less the present value (calculated using a discount rate equal to six percent (6%) per annum) of the fair rental value of the Premises for the same period (which fair rental value shall be calculated so as to include a reasonable vacancy period for reletting the Premises and deductions for reasonable expenses and inducements incurred by Landlord to achieve such reletting, including without limitation attorneys’ fees and expenses, brokerage fees, advertising costs, rent abatements, tenant improvement allowances and the like).

(f)Tenant’s Property. All property of Tenant removed from the Premises by Landlord or which becomes Landlord’s property pursuant to any provisions of this Lease or by law may be handled, removed or stored by Landlord at the cost and expense of Tenant, and Landlord shall in no event be responsible for the value, preservation or safekeeping thereof. Tenant shall pay Landlord for all expenses incurred by Landlord in such removal and for storage charges for such property so long as the same shall be in Landlord’s possession or under Landlord’s control. All property not removed from the Premises or retaken from storage by Tenant on or before the end of the Term, however terminated, or the termination of Tenant’s right of possession, shall, at Landlord’s option, be conclusively deemed to have been conveyed by Tenant to Landlord as by bill of sale, without further payment or credit by Landlord to Tenant.

32

(g)Bankruptcy Acceptance or Rejection. If Landlord shall not be permitted to terminate this Lease or Tenant’s right of possession of the Premises under the Bankruptcy Code, Tenant on behalf of itself as a tenant-in-possession or on behalf of any bankruptcy trustee for Tenant (alternatively referred to as “Tenant” in this Section 19(g)) agrees, within sixty (60) days after request by Landlord to the bankruptcy court having jurisdiction over Tenant’s bankrupt estate (the “Bankruptcy Court”), to assume or reject this Lease, and Tenant agrees not to seek or request any extension or continuation of such time in any bankruptcy proceeding to assume or reject this Lease.

Tenant’s right to assume this Lease as aforesaid shall be expressly conditioned upon Tenant fully satisfying the requirements under Section 365(b)(1) of the Bankruptcy Code, as such Section may be amended from time to time. In no event after such assumption of this Lease shall any then-existing Default remain uncured for a period in excess of the earlier of ten (10) days or the time period for curing such default as set forth herein. Failure to cure such default within such time shall constitute a Default hereunder.

Landlord and Tenant agree that adequate assurance of performance of this Lease, as set forth in Section 365(b)(1) of the Bankruptcy Code, as such Section may be amended from time to time, with respect to any monetary Default under this Lease, shall be in the form of cash or immediately available funds in an amount equal to at least the amount of such monetary Default so as to assure the Landlord that it will realize the amount of such Default.

If Tenant assumes this Lease and proposes to assign this Lease pursuant to the provisions of the Bankruptcy Code to any person or entity who shall have made a bona fide offer to accept an assignment of this Lease, then notice of such proposed assignment, setting forth (i) the name and address of such person or entity, (ii) all of the terms and conditions of such offer, and (iii) the adequate assurance to be provided Landlord to assure such person’s or entity’s future performance under this Lease, shall be given to Landlord by Tenant within twenty (20) days after receipt of such offer by Tenant and in no event later than ten (10) days prior to the date that Tenant shall make application to the Bankruptcy Court for authority and approval to enter into such assumption and assignment. In addition, Landlord shall thereupon have the right of first refusal, to be exercised by notice to Tenant given within ten (10) days prior to the effective date of such proposed assignment, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer made by such person or entity, less any brokerage commissions which may be payable out of any consideration to be paid by such person or entity for the assignment of this Lease.

Any person or entity to which this Lease is assigned pursuant to the provisions of the Bankruptcy Code shall be deemed, without further act or deed, to have assumed all of the obligations arising under this Lease on and after the date of such assignment; provided, however, that any options to renew or extend the Term of this Lease, and any right of offer or refusal or other options or rights to lease additional space in the Building shall be terminated effective as of the date on which such petition was filed with the Bankruptcy Court. Any such assignee shall upon written demand execute and deliver to Landlord an instrument confirming such assumption of this Lease on such terms. Nothing contained in this Section shall, in any way, constitute a waiver of any provisions of this Lease relating to assignment or subletting.

All monies or other considerations payable by Tenant or otherwise to be delivered to or on behalf of Landlord under this Lease, whether or not expressly denominated as Rent hereunder, shall constitute rent for the purposes of Section 502(b)(6) of the Bankruptcy Code, as such Section may be amended from time to time, and be the sole property of Landlord.

From and after the date of the filing of any petition with the Bankruptcy Court, to the extent permitted by applicable Laws, Landlord shall have no obligation to provide any services or utilities to the Premises as herein required, unless and until Tenant shall have paid and be current in all payments or other

33

charges therefor. Such payments and charges shall constitute administrative charges or expenses under Section 507(a)(1) of the Bankruptcy Code, as such Section may be amended from time to time.

(h)Waiver of Notices Not Provided for in this Lease. Tenant expressly waives the service of any notice of intention to terminate this Lease or to re-enter the Premises and waives the service of any demand for payment of Rent or for possession and waives the service of any and every other notice or demand prescribed by any ordinance, statute or other law (except as expressly otherwise provided in this Lease) and agrees that the breach of any covenants or agreements provided in this Lease shall, in and of itself, without the service of any notice or demand whatever (except as expressly otherwise provided in this Lease), constitute a forcible detainer by Tenant of the Premises.

(i)WAIVER OF TRIAL BY JURY. LANDLORD AND TENANT HEREBY DO WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER ON ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S USE OF OR OCCUPANCY OF THE PREMISES OR ANY CLAIM OF INJURY OR DAMAGE AND ANY EMERGENCY STATUTORY OR ANY OTHER STATUTORY REMEDY. IF LANDLORD COMMENCES ANY SUMMARY PROCEEDING FOR NON-PAYMENT OF RENT, TENANT WILL NOT INTERPOSE ANY COUNTERCLAIM OF WHATEVER NATURE OR DESCRIPTION IN ANY SUCH PROCEEDING UNLESS SUCH COUNTERCLAIM IS A COMPULSORY COUNTERCLAIM WHICH TENANT WOULD LOSE ITS ABILITY TO RAISE IF NOT RAISED IN SUCH PROCEEDING.

20.RIGHTS OF MORTGAGEES AND GROUND LESSORS.

(a)Subordination of Lease. Landlord may have heretofore or may hereafter encumber with a mortgage or trust deed the Building, the Land, the Project, any part thereof or any interest therein, may sell and lease back the Land, or any part of the Project, and may encumber the leasehold estate under such a sale and leaseback arrangement with a mortgage or trust deed. (Any such mortgage or trust deed is herein called a “Mortgage,” and the holder of any such mortgage or the beneficiary under any such trust deed is herein called a “Mortgagee.” Any such lease of the Land or other part of the Project is herein called a “Ground Lease,” and the lessor under any such lease is herein called a “Ground Lessor”). This Lease and the rights of Tenant hereunder shall be and are hereby expressly made subject to and subordinate at all times to any Mortgage and to any Ground Lease now or hereafter existing, and to all amendments, modifications, renewals, extensions, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security thereof. Tenant agrees to execute and deliver to Landlord such further commercially reasonable instruments consenting to or confirming the subordination of this Lease to any Mortgage and to any Ground Lease, containing a customary non-disturbance provision in favor of Tenant, and containing such other provisions which may be requested in writing by Landlord within twenty (20) days after Tenant’s receipt of such written request. Within a reasonable time following the date of any new Mortgage or Ground lease, Landlord shall cause the Mortgagee or Ground Lessor as applicable to enter into a commercially reasonable subordination, non-disturbance, and attornment agreement with Tenant.

(b)Notice of and Opportunity to Cure Defaults. Tenant agrees that if Landlord defaults in the performance or observance of any covenant or condition of this Lease required to be performed or observed by Landlord hereunder, Tenant will give written notice specifying such default by certified or registered mail, postage prepaid, to any Mortgagee or Ground Lessor of which Tenant has been notified in writing, and before Tenant exercises any right to terminate this Lease which Tenant may have on account of any such default of Landlord, such Mortgagee or Ground Lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default (or if such default cannot be cured within that time, then such additional time as may be necessary to cure such default, including but not limited to

34

commencement of foreclosure proceedings or other proceedings to acquire possession of the mortgaged or leased estate, if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or Ground Lessor is prevented from commencing or pursuing such foreclosure proceedings or other proceedings to acquire possession of the mortgaged or leased estate by reason of Landlord’s bankruptcy.

(c)Rights of Successors. If any Mortgage is foreclosed, or Landlord’s interest under this Lease is conveyed or transferred in lieu of foreclosure, or if any Ground Lease is terminated:

(i)No person or entity which as the result of any of the foregoing has succeeded to the interest of Landlord in this Lease (any such person or entity being hereafter called a “Successor”) shall be liable for any default by Landlord or any other matter which occurred prior to the date such Successor succeeded to Landlord’s interest in this Lease, nor shall such Successor be bound by or subject to any offsets or defenses which Tenant may have against Landlord or any other predecessor in interest to such Successor, provided that Successor shall be liable for curing any default which remains ongoing.

(ii)Upon request of any Successor, Tenant will attorn to such Successor, as Landlord under this Lease, subject to the provisions of this Section 20(c) and Section 20(e), and will execute and deliver such instruments as may be necessary or appropriate to evidence such attornment within ten (10) days after receipt of a written request to do so.

(iii)No Successor shall be bound to recognize any prepayment of more than one month’s Monthly Rent and Additional Rent.

(iv)No Successor shall be bound to recognize any amendment or modification of this Lease made without the written consent of the Mortgagee or Ground Lessor (as the case may be) to the extent such consent is required under the Mortgagee’s loan documents or the Ground Lessor’s lease, as applicable.

(d)Subordination of Mortgage. Notwithstanding anything to the contrary contained herein, any Mortgagee may subordinate, in whole or in part, its Mortgage to this Lease by sending Tenant notice in writing subordinating all or any part of such Mortgage to this Lease, and Tenant agrees to execute and deliver to such Mortgagee such further commercially reasonable instruments consenting to or confirming the subordination of all or any portion of its Mortgage to this Lease and containing such other provisions which may be requested in writing by such Mortgagee within ten (10) business days after Tenant’s receipt of such written request.

(e)Liability of Mortgagee and Ground Lessor. Whether or not any Mortgage is foreclosed or any Ground Lease is terminated, or any Mortgagee or Ground Lessor succeeds to any interest of Landlord under this Lease, no Mortgagee or Ground Lessor shall have any liability to Tenant for any security deposit paid to Landlord by Tenant hereunder, unless such security deposit has actually been received by such Mortgagee or Ground Lessor.

(f)Requests by Mortgagee or Ground Lessor. Should any prospective Mortgagee or Ground Lessor require a modification or modifications of this Lease, which modification or modifications will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, in the reasonable judgment of Tenant, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever reasonable documents are required therefor and deliver the same to Landlord within ten (10) business days following written request therefor. Should any prospective Mortgagee or Ground Lessor require execution of a short form of this

35

Lease for recording (containing, among other customary provisions, the names of the parties, a description of the Premises and the Term of this Lease), Tenant agrees to execute such short form of lease and deliver the same to Landlord within ten (10) business days following the request therefor.

21.DEFAULT UNDER OTHER LEASES. If the term of any lease, other than this Lease, heretofore or hereafter made by Tenant for any space in the Building, is terminated or terminable after the making of this Lease because of any default by Tenant or any such other party under such other lease, such fact shall empower Landlord, at Landlord’s sole option, to terminate this Lease by written notice to Tenant or to exercise any of the rights or remedies set forth in Section 19.

22.INSURANCE AND SUBROGATION.

(a)Tenant’s Insurance. Tenant shall carry insurance during the entire Term (and during any period of holdover) insuring Tenant, and insuring Landlord, Landlord’s constituent members and agents, all Mortgagees and Ground Lessors and their respective agents, partners and employees, with terms, coverages and in companies satisfactory to Landlord, and with such changes in insured parties and increase in limits as Landlord may from time to time request, but initially Tenant shall maintain the following coverages in the following amounts:

(i)Liability. Commercial general liability insurance covering bodily injury, property damage, and personal and advertising injury occurring within the Premises or arising out of the use thereof by Tenant or its agents, employees, officers, or invitees, visitors, and guests with limits of not less than One Million Dollars ($1,000,000) per occurrence and Two Million Dollars ($2,000,000) general aggregate, Two Million Dollars ($2,000,000) products and completed operations aggregate, and One Million Dollars ($1,000,000) personal injury and advertising liability aggregate. If this insurance applies to more than one location of the insured, then a per-location endorsement must be attached to the policy. Such policy shall contain an assumed contractual liability endorsement insuring performance by Tenant of the indemnity provisions of this Lease.

(ii)Property. All-risk property coverage or its equivalent form for the full insurable replacement value of (a) all Tenant’s furniture, fixtures, equipment, personal property, and other removable property and any Alterations made by or for the benefit of Tenant under the provisions of this Lease, and (b) all non-Building standard improvements Landlord or Tenant installs in the Premises.

(iii)Business Interruption. Business Interruption insurance for not less than twelve (12) months. The term “Business Interruption” means (A) net income, net profit, or loss before income taxes that would have been earned or incurred; and (B) continuing normal operating expenses, including payroll, incurred.

(iv)Worker’s Compensation. Worker’s compensation insurance in accordance with the applicable Laws, and employer’s liability insurance with a limit of at least One Million Dollars ($1,000,000) for bodily injury by accident (per accident), One Million Dollars ($1,000,000) for bodily injury by disease (policy limit), and One Million Dollars ($1,000,000) for bodily injury by disease (each person).

(v)Comprehensive Automobile Liability Insurance. Comprehensive automobile liability insurance ((including coverage for all owned, leased, non-owned and hired vehicles) in an amount not less than One Million Dollars ($1,000,000) for each accident.

36

(vi)Excess Liability. Excess liability insurance in an amount of not less than Five Million Dollars ($5,000,000) per occurrence and in the aggregate.

(vii)Additional Insurance. Tenant shall obtain such additional amounts of insurance and additional types of coverage as Landlord reasonably may request from time to time.

(b)Policy Requirements. All insurance policies carried by Tenant for the Premises shall (i) be issued in form acceptable to Landlord by good and solvent insurance companies qualified to do business in the jurisdiction in which the Building is located, reasonably satisfactory to Landlord and rated not lower than “Class A VIII,” as rated in the most recent edition of the A.M. Best Company, Inc.’s Key Rating Guide for insurance companies; (ii) designate as additional insureds Landlord (which shall also be loss payee specific to property coverage) and its members, shareholders, partners, officers, directors, employees, and managing agent, Landlord’s Mortgagee, and any other parties in interest from time to time designated in writing by notice from Landlord to Tenant; (iii) be written as primary policy coverage and not contributing with or in excess of any coverage that Landlord may carry; (iv) contain an endorsement to provide for thirty (30) days’ prior written notice to Landlord of any cancellation or other expiration of such policy or any Defaults thereunder, (v) contain an express waiver of any right of recovery (by subrogation or otherwise) by the insurance company against Landlord; and (vi) contain an assumed contractual liability endorsement insuring performance by Tenant of the indemnity provisions of this Lease. Tenant shall promptly pay all premiums for all insurance policies required under this Section 22 and shall deliver binding certificates of insurance evidencing such coverage and payment therefor before the earlier of the Commencement Date or the commencement of any work in the Premises, and renewals thereof shall be delivered to Landlord or Landlord’s designated agent before the expiration of any such policy. Neither the issuance of any insurance policy required hereunder nor the minimum limits specified herein for Tenant’s insurance coverage shall be deemed to limit or restrict in any way Tenant’s liability arising under or out of this Lease.

(c)Waiver of Subrogation. Landlord and Tenant each agree to have all property or physical damage insurance which it may carry endorsed with a clause providing that any release from liability of or waiver of claim for recovery from the other party or any of the parties named in Section 22(a) above or Released Parties described in Section 16(a) entered into in writing by the insured thereunder prior to any loss or damage shall not affect the validity of said policy or the right of the insured to recover thereunder. Tenant’s policy shall provide further that the insurer waives all rights of subrogation which such insurer might have against any of the parties named in Section 22(a) above. Tenant further agrees to first seek recovery under any applicable insurance policy before proceeding against Landlord. Notwithstanding the foregoing or anything contained in this Lease to the contrary, any release or waiver of claims shall not be operative, nor shall the foregoing endorsements be required, in any case where the effect of such release or waiver is to invalidate insurance coverage or invalidate the right of the insured to recover thereunder or increase the cost thereof (provided that in the case of increased cost the other party shall have the right, within ten (10) days following written notice, to pay such increased cost, thereby keeping such release or waiver in full force and effect).

(d)Landlord’s Insurance. Landlord shall carry during the Term hereof full replacement cost property insurance on the Building core and shell (including all base Building improvements at the Building, Tenant Alterations and all other alterations, additions or improvements to the Premises) against fire and other extended coverage perils in an amount sufficient to prevent Landlord from being deemed a co-insurer of the risks insured under the policy. Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it may deem necessary or prudent, including, but not limited to, commercial general liability insurance and rent loss insurance.

23.NONWAIVER. No waiver of any condition expressed in this Lease shall be implied by any neglect of Landlord to enforce any remedy on account of the violation of such condition, whether or

37

not such violation be continued or repeated subsequently, and no express waiver shall affect any condition other than the one specified in such waiver and that one only for the time and in the manner specifically stated. Without limiting Landlord’s rights under the provisions of Section 11, it is agreed that no receipt of money by Landlord from Tenant after the termination in any way 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 to Tenant prior to the receipt of such money. It is also 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 money due, and Landlord’s receipt and collection of said money shall not waive or affect any said notice, suit or judgment.

24.ESTOPPEL CERTIFICATE. Tenant agrees that from time to time upon not less than ten (10) business days) days’ prior written request by Landlord or any existing or prospective Mortgagee or Ground Lessor, Tenant shall, and Tenant shall cause any subtenant, licensee, concessionaire or other occupant of the Premises claiming by, through or under Tenant, to complete, execute and deliver to Landlord or Landlord’s designee or to any existing or prospective Mortgagee or Ground Lessor, a written estoppel certificate certifying (a) that this Lease is unmodified and is in full force and effect (or if there have been modifications, that this Lease, as modified, is in full force and effect and setting forth the modifications); (b) the amounts of the monthly installments of Monthly Rent and Additional Rent then required to be paid under this Lease; (c) the date to which Rent has been paid; (d) that to Tenant’s knowledge, Landlord is not in default under any of the provisions of this Lease, or if in default, the nature thereof in detail and what is required to cure same; and (e) such other information concerning the status of this Lease or the parties’ performance hereunder reasonably requested by Landlord or the party to whom such estoppel certificate is to be addressed.

25.TENANT CORPORATION, LIMITED LIABILITY COMPANY OR PARTNERSHIP. In case Tenant is a corporation or a limited liability company, (a) Tenant represents and warrants that this Lease has been duly authorized, executed and delivered by and on behalf of Tenant and constitutes the valid and binding agreement of Tenant in accordance with the terms hereof, and (b) if Landlord so requests, Tenant shall provide Landlord with evidence reasonably satisfactory to Landlord confirming the foregoing. In case Tenant is a partnership, (a) Tenant represents and warrants that all of the persons who are general or managing partners in said partnership have executed this Lease on behalf of Tenant, or that this Lease has been executed and delivered pursuant to and in conformity with a valid and effective authorization therefor by all of the general or managing partners of such partnership, and is and constitutes the valid and binding agreement of the partnership and each and every partner therein in accordance with its terms, to the extent permitted by law, and (b) if Landlord so requests, Tenant shall provide Landlord with evidence reasonably satisfactory to Landlord confirming the foregoing. Also, it is agreed that each and every present and future individual general partner, if Tenant is a partnership, in Tenant shall be and remain at all times jointly and severally liable hereunder, to the extent permitted by law, and that the death, resignation or withdrawal of any such partner shall not release the liability of such partner under the terms of this Lease unless and until Landlord shall have consented in writing to such release.

26.REAL ESTATE BROKERS. Each of Landlord and Tenant represents and warrants to the other that such party did not deal with any broker in connection with this Lease other than the Brokers identified in Section 1(b). Landlord hereby agrees to pay the brokerage commissions payable to said Brokers in accordance with a written agreement between Landlord and such Brokers. Each of Landlord and Tenant shall indemnify, defend and hold the other, its agents and their respective partners and employees, and the Project, harmless of, from and against any and all losses, damages, liabilities, claims, liens, costs and expenses, including without limitation court costs and reasonable attorneys’ fees and expenses, arising from any claims or demands of any other broker or brokers or finders for any commission alleged to be due such other broker or brokers or finders claiming to have dealt with Landlord and/or

38

Tenant in connection with this Lease or with whom Landlord and/or Tenant hereafter deals or whom Landlord and/or Tenant employs. Any representation or statement by a leasing company or other third party (or employee thereof engaged by Landlord as an independent contractor) that is made about the Premises or to the rest of the Building or the Project will not bind Landlord or modify this Lease, and Landlord will have no liability therefor except to the extent such representation is also contained in this Lease.

27.NOTICES. All notices, waivers, demands, requests or other communications required or permitted hereunder shall, unless otherwise expressly provided, be in writing and be deemed to have been properly given, served and received (a) if delivered personally or by same-day courier messenger, when delivered, (b) if sent by nationally recognized overnight courier, on the first (1st) business day after deposit with said courier, and (c) if mailed by United States Mail, certified or registered, postage prepaid, return receipt requested, on the date actually received or refused.

28.MISCELLANEOUS.

(a)Successors and Assigns. Each provision of this Lease shall extend to and shall bind and inure to the benefit not only of Landlord and Tenant, but also their respective heirs, legal representatives, successors and assigns, but this provision shall not operate to permit any assignment, subletting, mortgage, lien, charge, or other transfer or encumbrance contrary to the provisions of this Lease.

(b)Amendment. No modification, waiver or amendment of this Lease or of any of its conditions or provisions shall be binding upon a party hereto unless the same shall be in writing and signed by such party.

(c)Tenant. The word “Tenant” whenever used herein shall be construed to mean Tenants or any one or more of them in all cases where there is more than one Tenant; and the necessary grammatical changes required to make the provisions hereof apply either to corporations or other organizations, partnerships or other entities, or individuals, shall in all cases be assumed as though in each case fully expressed. In all cases where there is more than one Tenant, (a) the liability of each shall be joint and several, and (b) any one person or entity comprising Tenant may give any notice or approval required or permitted to be given by Tenant under this Lease, and such notice or approval shall be deemed binding upon all persons or entities comprising Tenant and may be relied upon by Landlord as if such notice or approval had been given by all persons or entities comprising Tenant.

(d)Expenses of Enforcement. The non-prevailing party shall pay upon written demand all of the reasonable costs, charges and expenses (including the court costs and fees and out-of-pocket expenses of attorneys, experts, and others retained by the prevailing party) incurred by the prevailing party in enforcing the terms of this Lease, and a party shall also pay such costs and expenses incurred by the other party in any litigation, negotiation or transaction in which said party causes the other party, without the other party’s fault, to become involved or concerned. Any amount due from Tenant to Landlord pursuant to this Section shall be deemed to be Rent due under this Lease.

The provisions of this subparagraph shall in no way relieve Tenant of the obligation to pay Rent or any other sums due hereunder on or before the date on which payment is due, nor shall the collection by Landlord of any amount under this subparagraph impair the ability of Landlord to collect any amount under Section 19 of this Lease.

(i)Interpretation. The invalidity of any provision of this Lease shall not, to the extent commercially reasonable, impair or affect in any manner the validity, enforceability or effect of the rest of this Lease.

Tenant shall similarly be excused for delay in the performance of any obligation hereunder, provided (i) nothing contained in this Section or elsewhere in this Lease shall be deemed to excuse or permit any delay in the payment of Rent, or any delay in the cure of any default which may be cured by the payment of money, and (ii) no reliance by Tenant upon this Section shall limit or restrict in any way Landlord’s right of self-help as provided in this Lease.

Except as provided in the following sentence, any right reserved to Landlord under this Lease

41

may be exercised by Landlord, any of its constituent members, the property manager of the Building, or any agent, contractor or designee of any of them. Any notice, demand, consent or approval which may be given by Landlord under this Lease may be given only by Landlord, any constituent member of Landlord, the property manager of the Building, or any agent or attorney of any of them.

(p)Entire Agreement. This Lease contains the entire agreement between Landlord, and Tenant with respect to its subject matter, and all negotiations, considerations, representations, understandings and agreements, oral or written, which may have been previously made between any of the foregoing parties are incorporated and merged into this Lease.

If Tenant fails to timely perform any of its duties under this Lease, and such failure continues for ten (10) days after written notice from Landlord (except that no such notice or cure period shall be required in the case of an emergency, or in the case of a failure to maintain insurance required by this Lease), then Landlord shall have the right (but not the obligation), and without limiting any other rights or remedies available to Landlord, to perform such duty on behalf and at the expense of Tenant without further prior notice to Tenant, and all sums expended or expenses incurred by Landlord in performing such duty, together with interest thereon at the Default Rate accruing from and after the time so expended or incurred by Landlord until repaid by Tenant, shall be deemed to be Additional Rent under this Lease and shall be due and payable upon written demand by Landlord.

(s)Independent Covenants. This Lease shall be construed as though the covenants herein between Landlord and Tenant are independent and not dependent, and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord.

(t)UBIT. Notwithstanding any contrary provision of this Lease, Tenant shall not sublease all or any portion of the Premises under a sublease in which the rent is based on the net income or net profits of any person, since the revenues to be received by Landlord or the Trust from time to time in connection with this Lease may, as a result of such action, be subject to the Unrelated Business Income Tax under Sections 511 through 514 of the Code.

39.OPTION TO EXPAND.

(a)Provided that this Lease is in full force and effect and that no Default shall exist under this Lease (both at the time of the exercise of the right(s) described in this Section 39 and on the date of entry into the agreement incorporating the Expansion Space), Tenant shall have, and is hereby granted an option (the “Option to Expand”) to lease an additional 1,000-2,000 Rentable Area of the Building for storage purposes only (the “Expansion Space”). The Monthly Rent rate for the Expansion Space shall be twelve dollars ($12.00) per square foot of Rentable Area, and shall annually increase by $0.25 per square foot of Rentable Area.

(b)The Option to Expand shall be exercised by Tenant, if at all, by giving binding written notice (the “ROEO Notice”) thereof to Landlord.

(c)Within a commercially reasonable time after receiving the ROEO Notice, Landlord shall furnish to Tenant a notice (the “Expansion Space Proposal”) containing the material terms of the proposed lease in respect of the applicable portions of the Expansion Space, including (i) location of the Expansion Space (ii) the proposed effective date of the lease for the Expansion Space, and (iii) any other material terms which Landlord shall deem appropriate.

46

(d)Tenant shall have the option, exercisable by notice delivered to Landlord within ten (10) business days after Tenant’s receipt or refusal of receipt of Landlord’s Expansion Space Proposal, TIME BEING OF THE ESSENCE, to lease the Expansion Space upon such terms and conditions as are contained in the Expansion Space Proposal. If Tenant timely delivers to Landlord written notice of Tenant’s exercise of the Option to Expand for the Expansion Space, then, within ten (10) business days thereafter, the parties shall enter into an amendment to this Lease incorporating the Expansion Space as part of the Premises on the terms and conditions contained in the Expansion Space Proposal. If Tenant declines or fails to timely exercise its Right of Expansion, Landlord shall thereafter be free to lease the Expansion Space without regard to the restrictions contained in this Section 39 and on such terms and conditions as Landlord may decide in its sole discretion. Tenant may, however, give subsequent and additional ROEO Notices provided they are in accordance with this Section 39.

40.EXTENSION OPTION.

(a)Subject to the terms, provisions, covenants, and conditions of this Section 40, Tenant shall have, and is hereby granted, two (2) separate options (each, an “Extension Option”) to extend the Lease Term, each for additional period of five (5) years commencing on the end of the Initial Term (each, an “Extended Term”), or Extended Term, as the case may be. The Extension Option shall be exercised by Tenant, if at all, by giving binding written notice (the “Extension Notice”) thereof to Landlord on or before, but not later than six (6) months prior to the end of the Initial Term, or Extended Term (each, “Extension Option Exercise Date”). In the event that Tenant fails to deliver the Extension Notice to Landlord by each applicable Extension Option Exercise Date, Tenant shall be deemed to have irrevocably waived the Extension Option hereunder, and the same shall be and become null, void, and of no further force or effect, time being of the essence in the delivery of Tenant’s Extension Notice hereunder. The Extended Term and Initial Term may hereinafter collectively referred to as the “Term”.

(b)The Extended Term shall be on the same terms, covenants, and conditions of this Lease, excluding the provisions of this Section 40, and except for the payment of Monthly Rent during the Extended Term(s).

(c)The Monthly Rent during the Extended Term shall be the Market Rental Rate (as hereafter defined) applicable to such period. “Market Rental Rate” means the gross annual rate of rent, expressed in dollars per square foot of rental area, reserved in leases most recently consummated for office space in the Building and in Class A office buildings in the suburban submarket of Chicago with tenants of similar creditworthiness and stature to Tenant, for comparable space (taking into account the location of the floor and the building) for leases of similar duration inclusive of the prevailing market conditions, including concessions and other allowances for the renewal of existing leases in existing buildings for existing tenants.

(d)Within thirty (30) days following Landlord’s receipt of Tenant’s written request therefor, Landlord shall advise Tenant of Landlord’s determination of the Market Rental Rate at which Landlord is prepared to offer the Premises to Tenant for the Extended Term (“Landlord’s Market Rental Rate Notice”). In the event that Tenant disagrees with Landlord’s determination of the Market Rental Rate as set forth in Landlord’s Market Rental Rate Notice, Tenant may so advise Landlord thereof in writing within ten (10) days of receipt of Landlord’s Market Rental Rate Notice (the “Tenant Market Objection Notice”) and if Landlord and Tenant are unable to agree upon the Market Rental Rate within twenty (20) days of the Tenant Market Objection Notice, Tenant may, within twenty-five (25) days of the Tenant Market Objection Notice elect to i) forego its exercise of the Extension Option, or ii) jointly appoint a qualified commercial real estate broker to arbitrate and determine Market Rental Rate, which determination shall be binding on the parties. In the event Tenant fails to elect to forego its exercise of the Extension Option, as provided herein,

47

then Tenant shall be deemed to have accepted the Landlord’s Market Rent Rate and the Extension Option(s) shall continue in full force and effect.

(e)It shall be a condition of Tenant’s right to exercise either Extension Option that (i) neither this Lease, nor Tenant’s right to possession hereunder, shall have been terminated, (ii) Tenant is not then in Default under any of the terms, provisions, covenants, or conditions of this Lease at the time that Tenant delivers Tenant’s Extension Notice or upon the commencement of the Extended Term, (iii) Tenant is then leasing and occupying the entirety of the Premises at the time of delivery of Tenant’s Extension Notice and upon the commencement of the Extended Term, (iv) Tenant shall submit current audited and certified financial statements of Tenant (unless Tenant’s financial statements are not audited, in which case reviewed and certified statements shall be acceptable) to Landlord concurrently with Tenant’s Extension Notice, and (v) there has been no material adverse change in the financial condition of Tenant, as reasonably determined by Landlord, at the time that Tenant delivers its Extension Notice or upon the commencement of the Extended Term.

(f)In the event that Tenant exercises Tenant’s Extension Option under this Section 40, Tenant agrees to execute and deliver to Landlord an amendment to this Lease setting forth the terms of such Extension Option(s) within ten (10) business days following the delivery of such amendment to Tenant hereunder.

42.RIGHT OF FIRST REFUSAL.

(a)During the period commencing on the Commencement Date and continuing until the end of the Term (the “ROFR Period”), provided that this Lease is in full force and effect and that no Default shall exist under this Lease (both at the time of the exercise of the right(s) described in this Section 42 and on the date of entry into the agreement incorporating the ROFR Space [as hereinafter defined]), Tenant shall have an ongoing right (the “ROFR”), to lease certain premises on the (i) fourth (4th) floor of the Building and adjacent to the Office Premises, and (ii) (i) first (1st) floor of the Building and adjacent to the Warehouse Premises, each as shown on Exhibit M (the “ROFR Space”) as provided in this Section 42.

(b)Notwithstanding anything set forth in this Section 42 to the contrary, Tenant acknowledges and agrees that Landlord shall have the sole discretion to determine the size, configuration, and/or suites comprising a ROFR Space and whether to market and lease a ROFR Space by itself or in combination with other contiguous suites.

(c)Subject to the foregoing, Landlord shall periodically give Tenant written notice (“ROFR Notice”) of the Major Business Terms, as defined below, of a written proposal that Landlord has made to or received from an unaffiliated third party (the “Prospect”), and which Landlord or such third party, as applicable, is willing to accept, for the applicable portions of the ROFR Space (the “ROFR Proposal”). As used herein, “Major Business Terms” shall mean, to the extent applicable, the RSF, lease term, Rentable Area of the ROFR Space, tenant improvement allowance, commencement date, and any other concessions.

(d)Tenant shall have the option, exercisable by notice delivered to Landlord within five (5) business days after Tenant’s receipt or refusal of receipt of Landlord’s ROFR Proposal, TIME BEING OF THE ESSENCE, to lease all, but not less than all, of the ROFR Space upon the same terms and conditions as are contained in the ROFR Proposal, subject to the terms of this Section 42. If Tenant timely delivers to Landlord written notice of Tenant’s exercise of the ROFR for the ROFR Space, then, within ten (10) business days thereafter, the parties shall enter into an amendment to this Lease incorporating the ROFR Space as part of the Premises on the terms and conditions contained in the ROFR Proposal.

(e)If Tenant declines or fails to timely exercise its ROFR, Landlord shall thereafter be free to lease the ROFR Space on substantially the same Major Business Terms as in the ROFR Proposal; provided however, If Landlord agrees to a lease of the ROFR Space upon terms that are substantially more favorable than the terms set forth in the ROFR Proposal to Tenant, Tenant shall once again have a ROFR with respect to the ROFR Space and Landlord shall deliver a new ROFR Proposal to Tenant reflecting the revised terms of the proposal to the Prospect in accordance with the provisions of this Section 42. For purposes hereof, the Major Business Terms offered to the Tenant shall be deemed to be substantially more favorable than the terms set forth in the ROFR Proposal if there is more than a six percent (6%) reduction in the net present value of the economic terms in the ROFR Proposal.

(f)If Landlord fails to lease the ROFR Space within the six (6) months following the date of the ROFR Proposal, the ROFR shall be reinstated, and, Landlord will be required to give Tenant a ROFR Proposal in accordance with the provisions of Section 42.

(g)In the event the ROFR Proposal is given on or before the last day of the twenty-fourth (24th) full calendar month after the Commencement Date, the terms of the Lease for the ROFR Space shall be on the same terms as those in the Lease including but not limited to the Rent rate and prorating allowances based upon the Term remaining.

(h)Notwithstanding anything herein to the contrary, the ROFR shall automatically terminate and become null and void upon the earlier to occur of: (a) the termination of Tenant’s right to possession of the Premises; (b) the assignment by Tenant of this Lease, in whole or in part, except to a Tenant Affiliate; or (c) the sublease by Tenant of all or any part of the Premises demised under the Lease, except to a Tenant Affiliate.

43.LEASE COMMENCEMENT/ACCEPTANCE OF PREMISES. At Landlord’s request, Landlord and Tenant shall enter into a commencement letter agreement (the “Commencement Letter”) in form substantially similar to that attached hereto as Exhibit F. Tenant’s failure to execute and return the Commencement Letter, or to provide written objection to the statements contained in the Commencement Letter, within fifteen (15) days shall be deemed an approval by Tenant of the statements contained therein.

THIS WORK LETTER is hereby incorporated as part of that certain Office Lease Agreement (“Lease”) made and entered into by and between HOFFMAN ESTATES ACQUISITIONS LLC, a Delaware limited liability company, and HOFFMAN ESTATES ACQUISITIONS II LLC, a Delaware limited liability company (collectively, “Landlord”) and CAMBIUM NETWORKS, INC., a Delaware corporation (“Tenant”).

W I T N E S S E T H:

WHEREAS, Landlord and Tenant are hereby entering into the above‑described Lease to which this Work Letter is being attached, which Lease demises certain Premises (as defined in the Lease; all capitalized terms used but not otherwise defined herein shall have the meaning as set forth in the Lease) in the office building located at 2000 Center Drive, Hoffman Estates, Illinois 60192 (a/k/a 2000 AT&T Center Drive, Hoffman Estates, Illinois 60192) (the “Building”); and

WHEREAS, certain tenant improvement work is to be completed on the Premises;

NOW, THEREFORE, for and in consideration of the agreement to lease the Premises and pay Rent and the mutual covenants contained herein, the parties agree as follows:

1.TURNOVER. Landlord shall deliver the Premises to Tenant for the construction of Tenant’s Work (as hereinafter defined) as provided in the Lease.

2.TENANT’S WORK. Tenant, at its sole cost and expense, but subject to payment of the Allowance (as hereinafter defined) as provided under Paragraph 9 below, shall perform, or cause to be performed, all work described in the Lease as the “Tenant’s Work” and desired by Tenant for its initial occupancy of the Premises (herein also referred to as the “Tenant’s Work”), all in accordance with the Plans (as hereafter defined) submitted to and approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed as described in Paragraph 3(b) below). The Tenant’s Work shall be constructed in a good and workmanlike fashion, in accordance with the requirements set forth herein and in compliance with applicable Laws, including, without limitation, the ADA, and with the construction-related rules and regulations for the Building from time to time, as such construction-related rules and regulations may be revised from time to time (herein, the “Construction Rules”). Landlord’s review and approval of the Plans or any other submission of Tenant shall create no responsibility or liability on the part of Landlord for such compliance or for their completeness or design sufficiency. The issuance of a certificate of occupancy by the Village of Hoffman Estates shall be conclusive evidence that Tenant’s Work is in compliance with the Construction Rules and this Section 2.

3.PRE‑CONSTRUCTION ACTIVITIES.

(a)Prior to commencing any of the Tenant’s Work, Tenant shall submit the following information and items to Landlord for Landlord’s review and, with respect to the items described in subclauses (iii), (v),

B-1

(vi) and (vii) below, approval (which approval shall not be unreasonably withheld, conditioned, or delayed as described in Paragraph 3(b) below):

(i)A detailed construction schedule containing the major components of the Tenant’s Work and the estimated time required for each, including the scheduled commencement date of construction of the Tenant’s Work and the estimated date of completion of construction.

(ii)An itemized statement of estimated construction costs, including permits and architectural and engineering fees.

(iii)The names and addresses of Tenant’s contractors (and the contractor’s subcontractors and vendors) to be engaged by Tenant for the Tenant’s Work and of any construction manager proposed to be engaged by Tenant for the Tenant’s Work (collectively, “Tenant’s Contractors”). Landlord has the right to approve or disapprove Tenant’s Contractors, which approval shall not be unreasonably withheld, conditioned, or delayed. Tenant shall not employ as Tenant’s Contractors any persons or entities so disapproved by Landlord. If Landlord has affirmatively approved only certain contractor(s) and/or subcontractor(s) from Tenant’s list, Tenant shall employ as Tenant’s Contractors only those persons or entities so approved.

(iv)Tenant’s Architect’s (as hereinafter defined) written statement that Tenant’s Architect has visited the site, inspected and verified existing conditions as such conditions affect the Plans and construction of the Tenant’s Work and that Tenant’s Architect has verified and confirmed the itemized statement of estimated construction costs delivered under Paragraph 3(a)(ii) above.

(v)Security in form and substance reasonably acceptable to Landlord in order to secure Tenant’s ability to pay any excess costs for the Tenant’s Work above the Allowance being provided by Landlord hereunder.

(vi)Certified copies of certificates of insurance as hereinafter described. Tenant shall not permit Tenant’s Contractors to commence work until the required insurance has been obtained and certificates have been delivered to Landlord.

(vii)The Plans for the Tenant’s Work which Plans shall be subject to Landlord’s approval in accordance with Paragraph 3(b) below.

Tenant will update such information and items by written notice to Landlord of any changes (which, as to the items described in subclauses (iii), (v), (vi) and (vii) above, shall be subject to Landlord’s review and reasonable approval). Landlord shall promptly (or as otherwise required by this Work Letter) review all submissions made by Tenant.

(b)As used herein the term “Plans” shall mean full and detailed architectural and engineering plans and specifications covering the Tenant’s Work (including, without limitation, architectural, mechanical, electrical, life safety, fire protection and plumbing working drawings for the Tenant’s Work). The Plans shall include the minimum information shown on Attachment 1 attached hereto and incorporated herein. Subject to Landlord’s payment of the Allowance, Tenant shall pay all costs and expenses of preparing the Plans. The Plans shall be subject to Landlord’s approval (not to be unreasonably withheld,conditioned or delayed, as hereinafter described) and the approval of all local governmental authorities requiring approval, if any. Landlord shall give its approval or disapproval (giving reasonable detailed reasons in case of disapproval) of the Plans within ten (10) business days after their delivery to Landlord with Tenant’s express written request for Landlord’s approval thereof. Landlord agrees not to unreasonably withhold its approval of said Plans; provided, however, that Landlord shall not be deemed to have acted unreasonably if it

B-2

withholds its consent because, in Landlord’s reasonable opinion: (i) the Tenant’s Work is likely to adversely affect Building systems, the structure of the Building or the safety of the Building and its occupants; (ii) the Tenant’s Work would adversely affect Landlord’s ability to furnish services to Tenant or other tenants; (iii) the Tenant’s Work would materially increase the cost of operating the Building; (iv) the Tenant’s Work would violate applicable Laws; (v) the Tenant’s Work contains or would require the use of hazardous or toxic material in any unlawful manner; (vi) the Tenant’s Work would adversely affect the appearance of the Building; or (vii) the Tenant’s Work would adversely affect the common areas of the Building or another tenant’s premises. The foregoing reasons, however, shall not be exclusive of the reasons for which Landlord may withhold consent, whether or not such other reasons are similar or dissimilar to the foregoing. Landlord shall cooperate with Tenant by discussing or reviewing preliminary plans and specifications at Tenant’s request prior to completion of the full, final detailed Plans in order to expedite the preparation of and the subsequent approval process concerning the final Plans. If Landlord notifies Tenant that changes are required to the final Plans submitted by Tenant, Tenant shall submit to Landlord, for its approval, the Plans amended in accordance with the changes so required. Such submission of revised Plans shall be accompanied by a written response from Tenant specifically responding to any disapprovals or other responses delivered by Landlord to Tenant. Landlord shall give its approval or disapproval (giving reasonably detailed reasons in case of disapproval) of any such revised Plans within five (5) business days after their delivery to Landlord with Tenant’s express written request for Landlord’s approval thereof. The Plans shall also be revised, and the Tenant’s Work shall be changed, to incorporate any work required in the Premises by any local governmental field inspector (all subject to Landlord’s reasonable approval thereof). Landlord’s approval of the Plans shall in no way be deemed to be acceptance or approval of any element therein contained which is in violation of applicable Laws. Without limitation of any other provision hereof, in the event Tenant elects to employ an engineer designated by Landlord in the preparation of any portion of the Plans, or for the performance of any portion of Tenant’s Work, Tenant shall employ and be responsible for all fees of said engineer in preparing the Plans or portion thereof and for any portion of Tenant’s Work performed by said engineer. In the event Tenant has elected not to employ Landlord’s designated engineer in the preparation of the Plans, Landlord reserves the right to have the Plans reviewed by Landlord’s designated engineer at Tenant’s expense.

(c)Upon Landlord’s approval of the Plans, at Tenant’s written request therefor, Landlord and Tenant shall agree in writing on any affixed appurtenances which are part of Tenant’s Work which Tenant shall be required to remove upon the expiration of the Lease (which removal requirement shall only be imposed by Landlord if such items are “non-customary”, which, for purposes hereof, means that Landlord reasonably determines that such item or items would be hazardous or costly to so remove or that such item or items are not customary for office tenant usage at similar Class A office buildings, provided that such removal requirement shall, in any event (unless Landlord otherwise directs, at its sole discretion), be imposed with respect to all telecommunications and data cabling installed by or on behalf of Tenant underneath raised floors, if applicable, all of which shall be deemed “non-customary” for purposes of this Work Letter). Any such agreement entered into in writing by Landlord and Tenant shall be binding on Landlord and Tenant at expiration of the Lease.

(d)No Tenant’s Work shall be undertaken or commenced by Tenant in the Premises until:

(i)The Plans for the Premises have been submitted to and approved by Landlord (which approval shall not be unreasonably withheld, conditioned, or delayed as provided in Paragraph 3(b) hereinabove).

(ii)All necessary building permits have been obtained by Tenant.

B-3

(iii)All required insurance coverages have been obtained by Tenant, it being understood that failure of Landlord to receive evidence of such coverage upon commencement of the Tenant’s Work shall not waive Tenant’s obligations to obtain such coverages.

(iv)Items required to be submitted to Landlord prior to commencement of construction of the Tenant’s Work have been so submitted and have been approved, where required (which approval shall not be unreasonably withheld, conditioned or delayed as provided herein).

(e)Tenant shall have the right to retain its own construction manager for construction of the Tenant’s Work, subject to Landlord’s reasonable approval as provided herein, in which event Landlord shall not charge any review or supervision fees associated with the Tenant’s Work. Notwithstanding anything to the contrary herein, Tenant shall, in any event (i.e., whether or not it has engaged Landlord to act as construction manager), pay or reimburse Landlord for all actual reasonable out-of-pocket costs and expenses paid or incurred by Landlord in connection with its review of the Plans and other submittals hereunder (including third-party architectural and engineering review) and subject to use of Allowance proceeds therefor as provided in Paragraph 9 below. Landlord agrees to provided Tenant with reasonable prior written notice of Landlord’s intent to retain any third-party professional to review the Plans and agrees to consult with Tenant to minimize any costs associated therewith.

4.DELAYS. Tenant shall be responsible for Rent and all other obligations as set forth in the Lease from the Commencement Date, regardless of the degree of completion of the Tenant’s Work on such date, and no such delay in completion of the Tenant’s Work shall affect the Commencement Date, or relieve Tenant of any of its obligations under said Lease.

5.CHARGES AND FEES. Subject to Paragraph 9 below, Tenant shall be responsible for all costs and expenses attributable to the Tenant’s Work.

6.CHANGE ORDERS. All changes (other than de minimis changes based upon field conditions) to the final Plans requested by Tenant must be approved by Landlord in advance of the implementation of such changes as part of the Tenant’s Work (not to be unreasonably withheld, conditioned or delayed as provided above). Landlord shall give its written approval or disapproval (giving reasonably detailed reasons in case of disapproval) of any such changes to the final Plans requested by Tenant, which approval or disapproval shall be given within five (5) business days after delivery of such requested changes to Landlord with Tenant’s express written request for Landlord’s approval thereof. Subject to Paragraph 9 below, Tenant shall be responsible for all costs and expenses attributable to any changes. All delays caused by Tenant-initiated change orders, including, without limitation, any stoppage of work during the change order review process, are solely the responsibility of Tenant and shall cause no delay in the Commencement Date or payment of Rent and performance of other obligations set forth in the Lease.

7.STANDARDS OF DESIGN AND CONSTRUCTION AND CONDITIONS OF TENANT’S PERFORMANCE. All work done in or upon the Premises by Tenant shall be done according to the standards set forth in this Paragraph 7, except as the same may be expressly modified in the Lease or in the Plans approved by both Landlord and Tenant.

(a)Tenant’s Plans and all design and construction of the Tenant’s Work shall comply with applicable Laws and industry standards, including, but not limited to, requirements of Landlord’s fire insurance underwriters and the requirements of the ADA, and with all Construction Rules (as described in Paragraph 2 above), all to the extent in effect from time to time. Approval by Landlord of the Plans shall not constitute a waiver of this requirement or assumption by Landlord of responsibility for compliance. Where several sets of applicable Laws must be met, the strictest shall apply where not prohibited by another Applicable Laws.

B-4

(b)Tenant shall, at its own cost and expense, but subject to payment by Landlord of the Allowance under Paragraph 9 below, obtain all required building permits and, when construction has been completed, shall, at its own cost and expense, obtain an occupancy permit for the Premises, a copy of which shall be delivered to Landlord. Tenant’s failure to obtain such permits shall not cause a delay in the Commencement Date or the payment of Rent and performance of other obligations under the Lease.

(c)Tenant’s Contractors shall be licensed contractors, capable of performing quality workmanship and working in harmony with Landlord’s contractors and subcontractors and with other contractors and subcontractors in the Building. All work shall be reasonably coordinated with any other construction or other work in the Building. Landlord and Tenant shall cooperate with one another and with each such party’s respective contractors in all reasonable respects relative to work coordination matters.

(d)Landlord shall have the right, but not the obligation, to perform, on behalf of and for the account of Tenant, subject to reimbursement by Tenant, at Landlord’s actual out‑of‑pocket cost (but subject to application of the Allowance to the extent thereof), any work which Landlord deems necessary to be done on an emergency basis or which otherwise affects Building structure or systems, provided that the fees charged by Landlord are commercially reasonable. Landlord shall notify Tenant in writing as soon as possible upon Landlord’s determination of any work for which it has elected to undertake under this Paragraph 7(d).

(e)Tenant shall use only new, quality materials in the Tenant’s Work, except where explicitly shown in the Plans approved by Landlord and Tenant. Tenant shall obtain, promptly after completion of the Tenant’s Work, warranties of at least one (1) year duration from the completion of the Tenant’s Work against defects in workmanship and materials on all work performed and equipment installed in the Premises as part of the Tenant’s Work, a copy of which warranties shall be delivered to Landlord promptly following Tenant’s receipt of the same.

(f)Tenant and Tenant’s Contractors, in performing work, shall do so in conformance with the Construction Rules described in Paragraph 2 above, to the extent in effect for the Building from time to time. Tenant and Tenant’s Contractors shall make all reasonable efforts and take all reasonable steps appropriate to construction activities undertaken in similar Class A office buildings so as not to interfere with the operation of the Building and shall, in any event, comply with the aforementioned Construction Rules and with the Rules and Regulations from time to time which are permitted under the Lease. Tenant and Tenant’s Contractors shall take all reasonable precautionary steps to minimize dust, noise and construction traffic, and to protect their facilities and the facilities of others affected by the Tenant’s Work and to properly supervise same. Tenant shall not permit noise from construction of Tenant’s Work to unreasonably or materially disturb other tenants in the Building. Tenant’s Work which does so unreasonably or materially disturb other tenants shall be performed after regular working hours. Construction equipment and materials are to be kept within the Premises and delivery and loading of equipment and materials shall be done at such locations and at such time as Landlord shall reasonably direct so as not to burden the construction or operation of the Building.

(g)Upon not less than twenty-four hours’ written or oral notice to Tenant and Tenant’s failure to reasonably cure such matter within such 24-hour period, Landlord shall have the right to order Tenant or any of Tenant’s Contractors who unreasonably violate the requirements imposed on Tenant or Tenant’s Contractors in performing work to cease work and remove its equipment and employees from the Building (herein, a “Cease Order”), to the extent Landlord determines that such violation is likely to have a material adverse effect on the Building systems, structure or operations, the safety of the Building’s occupants, or to otherwise create any other type of hazardous condition, which Cease Order shall remain effective until such time as the violation which is the subject thereof has been cured. No such action properly taken by

B-5

Landlord shall delay the Commencement Date, or the payment of Rent and performance of other obligations under the Lease.

(h)Utility costs or charges for any service (including, but not limited to, HVAC, electrical, trash removal and the like) to the Premises shall be the responsibility of Tenant from the date Tenant commences the Tenant’s Work and shall be paid for by Tenant at Landlord’s rates (which rates shall reflect Landlord’s direct costs therefor, without any mark-up by Landlord). The initial premises under the Lease are separately metered for electricity (light and outlets), and Tenant shall make necessary arrangements with the electrical utility company for direct payment of electricity charges from and after the Possession Date under the Lease (whereupon Tenant shall no longer be responsible for payment to Landlord for such electricity costs as initially provided in the first sentence of this paragraph). Use of freight elevators and loading docks are all subject to reasonable scheduling by Landlord. Any use of the freight elevators will be at Tenant’s expense, in an amount equal to the actual out‑of‑pocket expenses (if any) incurred by Landlord or security personnel necessitated by such freight elevator usage. Tenant shall arrange and pay for removal of construction debris and shall not place debris in the Building’s waste containers. Except as provided above, there shall be no charge for use of freight elevators during normal construction hours of the Building in connection with performance of the Tenant’s Work and Tenant’s initial move into the Premises. Further, there shall be no charge for use of loading docks during normal business hours of the Building in connection with Tenant’s Work and Tenant’s initial move into the Premises (subject to the conditions for use of loading docks as described above).

(i)Subject to Section 8(g) of the Lease, Tenant shall permit Landlord and/or its representatives to have access to the Premises upon twenty-four (24) hours’ prior written notice (except that no notice shall be required in the case of an emergency), and the Tenant’s Work shall be subject to inspection, by Landlord and Landlord’s architects, engineers, contractors and other representatives, at all times during the period in which the Tenant’s Work is being constructed and installed and within a reasonable period following completion of the Tenant’s Work.

(j)Tenant shall notify Landlord upon completion of the Tenant’s Work and shall furnish Landlord and Landlord’s title insurance company with such further documentation as may be reasonably requested by Landlord to evidence same.

(k)Except as otherwise expressly provided herein, Tenant shall have no authority to deviate from the Plans in performance of the Tenant’s Work, except as authorized by Landlord and its designated representative in writing (which authorization shall not be unreasonably withheld, conditioned or delayed in accordance with the same standards for approval as described in Paragraph 3(b) above). Tenant shall furnish to Landlord “as‑built” drawings of the Tenant’s Work consisting of record drawings of the installed condition of each component of the Tenant’s Work completed from the Plans marked up daily in the field by the various trades. Such record drawings shall be submitted in a final package by Tenant’s general contractor to Landlord within ninety (90) days after completion of the Tenant’s Work. Final disbursement of any remaining amounts of the Allowance will not occur until such record drawings have been received by Landlord.

(l)Landlord shall have the right to require Tenant, at Tenant’s cost, to install and maintain proper access panels to utility lines, pipes, conduits, duct work and component parts of mechanical and electrical systems existing or installed in the Premises to the extent required by applicable Laws or otherwise reasonably identified by Landlord as part of its approval of the Plans.

(m)Tenant shall impose on and enforce all applicable terms of this Work Letter against Tenant’s Architect, Tenant’s Engineer (as hereinafter defined) and the other Tenant’s Contractors.

8.INSURANCE AND INDEMNIFICATION.

(i)Worker’s Compensation and Employer’s Liability Insurance with limits of not less than $1,000,000.00, or such higher amounts as may be required from time to time by any employee benefit acts or other statutes applicable where the work is to be performed, and in any event sufficient to protect Tenant’s Contractors from liability under the aforementioned acts.

(ii)Commercial General Liability Insurance including Broad Form Contractual, Broad Form Property Damage, Personal Injury, Completed Operations and Products coverages (such Completed Operations and Products shall be provided for a period of two (2) years after the date of final acceptance of the Tenant’s Work), and deletion of any exclusion pertaining to explosion, collapse and underground property damage hazards, with limits of not less than $5,000,000.00 per occurrence and having a general aggregate amount on a per location basis of not less than $5,000,000.00.

(iii)Comprehensive Automobile Liability Insurance including Owned, Non‑Owned and Hired Car coverages, with limits of not less than $1,000,000.00 combined single limit for both bodily injury and property damage.

(iv)“All‑risk” builder’s risk insurance upon the entire Tenant’s Work to the full insurable value thereof. This insurance shall include the interests of Landlord and Tenant (and their respective contractors and subcontractors of any tier to the extent of any insurable interest therein) in the Tenant’s Work and shall insure against the perils of fire and extended coverage and shall include “all‑risk” builder’s risk insurance for physical loss or damage including, without duplication of coverage, theft, vandalism and malicious mischief. Any loss insured under said “all‑risk” builder’s risk insurance is to be adjusted between Landlord and Tenant, as their interests may appear.

All policies (except the worker’s compensation policy) shall be endorsed to include as additional insured parties Landlord, Landlord’s mortgagee, and such additional persons as Landlord may designate. The waiver of subrogation provisions contained in the Lease shall apply to all insurance policies (except the worker’s compensation policy) to be obtained by Tenant pursuant to this paragraph. The insurance policy endorsements shall also provide that all additional insured parties shall be given thirty (30) days’ prior written notice of any reduction, cancellation or non‑renewal of coverage (except that ten (10) days’ notice shall be sufficient in the case of cancellation for non‑payment of premium) and shall provide that the insurance coverage afforded to the additional insured parties thereunder shall be primary to any insurance carried independently by said additional insured parties. Additionally, where applicable, each policy shall contain a cross‑liability and severability of interest clause.

(b)Without limitation of the indemnification provisions contained in the Lease, to the fullest extent permitted by applicable Laws, Tenant agrees to indemnify, protect, defend and hold harmless Landlord, Landlord’s contractors and Landlord’s architects, and their partners, members, directors, officers, employees and agents, from and against all claims, liabilities, losses, damages and expenses of whatever nature arising out of or in connection with the Tenant’s Work or the entry of Tenant or Tenant’s Contractors into the Building and the Premises, including, without limitation, mechanic’s liens or the cost of any repairs to the Premises or Building necessitated by activities of Tenant or Tenant’s Contractors and bodily injury to persons or damage to the property of Tenant, its employees, agents, invitees, licensees or others, except

B-7

and to the extent that such claims, liabilities, losses, damages and expenses arise out of the willful misconduct or negligent act or omission of Landlord or from Landlord’s breach of its obligations hereunder or under the Lease. It is understood and agreed that the foregoing indemnity shall be in addition to the insurance requirements set forth above and shall not be in discharge of or in substitution for same or any other indemnity or insurance provision of the Lease.

9.ALLOWANCE; PERIODIC PAYMENTS.

(a)Landlord shall make a contribution (the “Office Allowance” and “Warehouse Allowance”, as further defined below) towards the cost of Tenant’s Work (including, without limitation, the costs of construction (including demolition), furniture, installation and wiring of phone and data processing equipment, permits and inspections, space plans, design drawings and other architectural drawings) and toward moving costs and any other architectural fees in connection with the Tenant’s Work (herein, the “Allowance Permitted Costs”), in an amount estimated to be (and subject to the terms of the Final Space Plan Addendum) to (i) $2,700,000 (should the Office Space be comprised of 30,000 square feet of Rentable Area) for the portion of the Tenant’s Work being performed in the Office Space the (“Office Allowance”) (i.e., being $90.00 per square foot of Rentable Area of the Office Space), and (ii) $250,000 (should the Warehouse Space be comprised of 5,000 square feet of Rentable Area) for the portion of the Tenant’s Work being performed in the Warehouse Space (the “Warehouse Allowance”) (i.e., being $50.00 per square foot of Rentable Area of the Warehouse Space), on the terms and conditions hereinafter set forth. Landlord and Tenant acknowledge and agree that the Office Allowance shall only be allocated, used and distributed for the Tenant’s Work performed in the Office Space, and the Warehouse Allowance shall only be allocated, used and distributed for the Tenant’s Work performed in the Warehouse Space. The Office Allowance and Warehouse Allowance may collectively be referred to as the “Allowance”. If the cost of the Tenant’s Work is less than the Allowance, any excess Allowance, at the written request of Tenant, shall be applied by Landlord towards Rent due under the Lease as additional Abated Rent after the Third Rent Abatement Period. If the cost of the Tenant’s Work exceeds the Allowance required to be disbursed hereunder, Tenant shall have sole responsibility for the payment of such excess cost, and, at Landlord’s election, Tenant shall be obligated to pay its “pro‑rata share” (as defined in Paragraph 9(g) below) of the Allowance Permitted Costs when due from time to time (i.e., based upon the most recent estimates of the cost of the Tenant’s Work delivered by Tenant under Paragraph 3 above or otherwise furnished by Tenant, in certified form, upon Landlord’s request from time to time therefor) as an express condition for Landlord’s obligation to disburse any further portion of the Allowance, and in such event, Landlord shall have no obligation to further disburse any portion of the Allowance until Tenant’s pro‑rata share of the Allowance Permitted Costs have been so paid by Tenant.

(b)Periodically, but not more frequently than once per calendar month, Tenant may submit to Landlord a written payment request for costs of the Tenant’s Work incurred and not previously paid naming the parties to be paid, and the respective amounts of such payments, which payment request shall be accompanied by:

(i)A customary “sworn owner’s statement” signed by Tenant stating the various contracts entered into by Tenant for the Tenant’s Work and with respect to each: the total contract price of all labor, work, services and materials; the amounts theretofore paid thereon; the amount requested for the current disbursement; and the balance due for such labor, work, services and materials, after payment of the current disbursement, to complete the Tenant’s Work in accordance with the Plans;

(ii)A written application for payment from each of Tenant’s Contractors disclosed in the aforesaid sworn Tenant’s statement wherein each of Tenant’s Contractors certifies completion and the cost of that portion of the Tenant’s Work for which payment is requested (with designations for allocations between the Office Space and Warehouse Space, as applicable) and further certifies that

B-8

the cost to complete the Tenant’s Work remaining to be done under said contract will not exceed the balance due thereunder (without including in such balance any required retainages) and a statement in writing under oath or verified by affidavit of Tenant’s Contractor stating: the names of all persons, firms, associations, corporations or other parties by whom labor, materials, services or work will be rendered or furnished pursuant to the contract with Tenant’s Contractor; the nature of labor, work, services and materials to be rendered or furnished by each of the foregoing; the amounts (in the case of firm subcontracts) and estimated amounts (in other cases) to be paid for such labor, work, services and materials; the amounts theretofore paid thereon; the amount requested for the current disbursement; and the balance due for such labor, work, services and materials, after payment of the current disbursement, to complete the work described in such subcontract;

(iii)A statement from each of the subcontractors and materialmen disclosed in the aforesaid Tenant’s Contractor’s sworn statement, in writing under oath or verified by affidavit of a duly authorized agent of such subcontractor of the parties furnishing materials and labor to it or for their account, and of the amounts due or to become due each;

(iv)Certificate for payment executed by an architect acceptable to Landlord on American Institute of Architect’s Form G-702 and G-703; and

(v)Originals of partial waivers of lien from each of Tenant’s Contractors and all materialmen and vendors requesting payment covering such requested payment.

Provided that the foregoing deliveries have been made, and so long as a Default has not occurred under the Lease or this Work Letter, or a default beyond applicable notice and/or cure periods by Tenant has not occurred under any separate construction management agreement entered into between Tenant and Landlord, in each case for which Tenant has received written notice from Landlord, then Landlord shall disburse portions of the Allowance no later than the last day of the calendar month immediately succeeding the calendar month in which Tenant submits each such request therefor (provided that if Tenant cures any such default within applicable cure periods, then Landlord shall again be obligated to disburse said Allowance as provided herein).

(c)Landlord may make payments of the Allowance through a construction escrow established with Landlord’s title insurance company pursuant to which escrow said title company shall examine the sworn statements and lien waivers provided by Tenant and Tenant’s Contractors and, if so required by Landlord, insure against mechanic lien claims for work done through the date of Tenant’s Contractors’ most recent request for payment, in which case Tenant agrees to comply with the reasonable terms and conditions of such construction escrow. The escrowee’s charges therefor shall be paid for by Landlord. Notwithstanding anything to the contrary contained herein or in the Lease, in the event Landlord makes payments of the Allowance through a construction escrow as provided in this paragraph, Tenant’s Contractors may, at their own expense, arrange to provide “trailing” waivers (lien waivers which are dated up to thirty (30) days earlier than the contractor’s request for payment) if Landlord’s lender so permits and Landlord’s title insurance company nevertheless provides the insurance called for by this Paragraph.

(d)Within thirty (30) days after final completion and installation of the Tenant’s Work, Tenant shall submit to Landlord a detailed breakdown of the total amount of the costs of the Tenant’s Work, together with final waivers of liens, contractors’ affidavits, and architects’ certificates in such form as may be reasonably required by Landlord, Landlord’s title insurance company and Landlord’s lender, if any, from all parties performing labor or supplying materials or services in connection with the Tenant’s Work, showing that all of said parties have been compensated in full and waiving all liens in connection with the Premises and Building.

B-9

(e)Landlord has no obligation to disburse any portion of the Allowance during any period when a Default has occurred under the Lease or a default beyond applicable notice and/or cure periods by Tenant has occurred under any separate construction management agreement entered into between Tenant and Landlord, in each case for which Tenant has received written notice from Landlord. Disbursement of any portion of the Allowance shall not be deemed a waiver of Tenant’s obligation to comply with such provisions. Tenant shall be responsible for the appropriateness and completeness of the contractors’ affidavits and waivers of lien and approval of any of such work; Landlord shall have no responsibility for any of the foregoing.

(f)Landlord shall have the right to withhold a (i) ten percent (10%) retainage until the Tenant’s work is fifty (50%) complete, and thereafter, (ii) five percent (5%), until substantial completion of the Tenant’s work, from any disbursements of the Allowance otherwise required hereunder. Landlord shall disburse such retainage, together with the balance of the Allowance, upon Tenant’s satisfaction of the terms of Paragraph 7(k) above and the terms of this Paragraph 9 (including, without limitation the terms of Paragraph 9(b) and Paragraph 9(d) above) and Tenant’s final request for payment (which request shall be made no earlier than the Commencement Date) and certification that the entire Tenant’s Work has been performed and that the amounts for which payment is requested are due and owing, which disbursement shall be made no later than the last day of the calendar month immediately succeeding the calendar month in which the foregoing requirements are satisfied and in which there has been presentation by Tenant to Landlord of request for payment and appropriate and complete contractor’s affidavits and waivers of lien showing that the work covered thereby has been performed in the Premises.

(g)Notwithstanding anything contained in the Lease or in this Work Letter to the contrary, in no event shall Tenant be entitled to any portion of the Allowance at any time after the 12-month anniversary of the Possession Date. In the event that the cost of the Tenant’s Work and such other items for which the Allowance may be applied should for any reason be greater than the maximum Allowance provided by Landlord hereunder, Tenant shall have sole responsibility for the payment of such excess cost, and Tenant shall, at Landlord’s option, for each pending draw request, pay such portion of the pending draw request which is necessary so that Tenant has then paid, together with any previous payments made by Tenant on account of the Allowance Permitted Costs, an amount equal to Tenant’s pro‑rata share (as hereinafter defined) of the Allowance Permitted Costs, all as a condition to Landlord’s disbursement or further disbursement of portions of the Allowance, and all as otherwise described in Paragraph 9(a) above. For purposes of the foregoing, (A) Tenant’s “pro‑rata share” of the applicable Allowance Permitted Costs shall mean (1) the total amount of the Allowance Permitted Costs incurred to date, less (2) ”Landlord’s Share”; and (B) the term “Landlord’s Share” shall mean the total amount of Allowance Permitted Costs incurred as of the date of determination, multiplied by a fraction, the numerator of which is the total amount of the Allowance required hereunder and the denominator of which is the total amount of anticipated Allowance Permitted Costs (as such anticipated Allowance Permitted Costs are determined by Landlord, based on certified cost statements delivered by Tenant to Landlord from time to time, and in any event, delivered by Tenant to Landlord promptly upon Landlord’s request therefor). Tenant shall be solely responsible for timely payment of any costs associated with the Tenant’s Work incurred by Tenant and not otherwise consisting of Allowance Permitted Costs. Further, Tenant shall be responsible for payment of all costs associated with Allowance amounts retained by Landlord as permitted retainage hereunder, subject to reimbursement as part of the final disbursement of the Allowance described in Paragraph 9(f) above.
