1. The definitions and basic provisions set forth in the Basic Lease Information (the “Basic Lease Information”) executed by Landlord and Tenant contemporaneously herewith are incorporated herein by reference for all purposes.

2. Subject to the terms of this Lease, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises. Except with respect to any obligations of Landlord expressly provided in this Lease, including, but not limited to Sections 8(e) and 8(f) and Exhibits H-1 and H-2, Tenant accepts the Premises in its condition as of the Commencement Date, subject to all applicable laws, ordinances, and regulations. Tenant acknowledges that Landlord has made no representation or warranty as to the suitability of the Premises for the conduct of Tenant’s business, and Tenant waives any implied warranty that the Premises are suitable for Tenant’s intended purposes. The taking of possession of the Premises shall be conclusive evidence that Tenant has inspected and accepts the Premises and that the Premises were in good condition at the time possession was taken except with respect to the obligations of Landlord expressly provided in this Lease, including, but not limited to Sections 8(e) and 8(f) and Exhibits H-1 and H-2. Except as expressly provided in this Lease, in no event shall Landlord be liable for any defects in the Premises or for any limitation on its use.

3. If the Commencement Date is not the first day of a calendar month, then the Term shall be extended by the time between the Commencement Date and the first day of the next month. Landlord and Tenant acknowledge and agree that Tenant is currently occupying the Premises pursuant to that certain Lease (as amended from time to time, the “Existing Lease”) dated August 31, 2007 between Tenant, as tenant, and Landlord, as successor in interest to landlord thereunder. Effective as of the Commencement Date, the Existing Lease shall be deemed terminated, and neither Landlord nor Tenant shall have any obligations thereunder except to the extent accruing prior to the Commencement Date or expressly surviving the expiration of the Lease.

4. a. Payment. Tenant shall timely pay to Landlord the Basic Rental and all additional sums to be paid by Tenant to Landlord under this Lease, including the amounts set forth in Section 4.b. and Section 4.c., without deduction or set off (except as expressly provided in this Lease, including in connection with the Temporary Swing Space, or in Section 14 or Section 15), at Landlord’s Address (or such other address as Landlord may from time to time designate in writing to Tenant). Basic Rental shall be payable monthly in advance. The first monthly installment of Basic Rental shall be payable on the day after the Abatement Period so that Tenant is not entitled to more than five (5) total months of abatement; thereafter, monthly installments of Basic Rental shall be due on the first day of the next full calendar month after the Abatement Period and continuing on the first day of each succeeding calendar month during the Term. Basic Rental for any fractional month immediately following the Abatement Period shall be prorated based on 1/365 of the current annual Basic Rental for each day of the partial month this Lease is in effect, and shall be due on the day after the Abatement Period. Notwithstanding anything contained herein to the contrary, Landlord acknowledges and agrees that Tenant shall be entitled to a credit in an amount equal to any Rent (as defined in the Existing Lease) paid by Tenant to Landlord pursuant to the Existing Lease (but less the Janitorial Costs Tenant is required to pay (and has not yet

paid) for the portion of the Premises for which janitorial services are provided and the Temporary Swing Space) for the period commencing on the Commencement Date through the date of Lease execution (including but not limited to January 2017 and February 2017 installments of Fixed Annual Rent as defined in the Existing Lease) (“Rent Credit”). The Rent Credit shall be credited against the first monthly installment of Basic Rental and to each subsequent installment of Basic Rental until the Rent Credit has been fully applied and reduced to zero.

b. Excesses. Commencing on January 1, 2018, Tenant shall pay an amount (per each rentable square foot in the Premises) equal to the difference between the actual Basic Cost per rentable square foot in the Building in the applicable calendar year and the actual Basic Cost per rentable square foot in the Building incurred during the Base Year (“Basic Cost Excess”). In addition, commencing on the Commencement Date, Tenant shall pay an amount (per each rentable square foot in in the Premises) equal to (i) all costs which Landlord incurs in connection with snow and ice removal for the parking areas and sidewalks associated with the Building (“Snow Removal Cost”) that exceed $0.25 per rentable square foot per annum (“Snow Excess”), plus (ii) if Tenant does not elect to provide its own janitorial services as provided in Section 8.i, all costs which Landlord incurs in connection with performing janitorial services excluding the cost of all cleaning supplies which Tenant shall provide, at Tenant’s cost, for the Premises (“Janitorial Costs”) for the Building that exceed $1.00 per rentable square foot per annum (prorated, as appropriate, if janitorial is not provided to the entire Premises for the entire calendar year 2017) (“Janitorial Excess”; the Basic Cost Excess, Snow Excess and Janitorial Excess (if applicable) are each an “Excess” and collectively, the “Excesses”). Landlord may collect the amount for any Excess in a lump sum, to be due within thirty (30) days after Landlord furnishes to Tenant the Annual Cost Statement (defined below). Alternatively, Landlord may make a good faith estimate for any Excess to be due by Tenant for any calendar year or part thereof during the Term, and, unless Landlord delivers to Tenant a revision of such estimated Excess, Tenant shall pay to Landlord, on the first day of each calendar month, an amount equal to the estimated Excess for such calendar year or part thereof divided by the number of months in such calendar year during the Term. From time to time during any calendar year, Landlord may estimate and re-estimate any Excess to be due by Tenant for that calendar year and deliver a copy of the estimate or re-estimate to Tenant; provided that Landlord shall not estimate or re-estimate any Excess more than once in any calendar year. Thereafter, the monthly installments for the estimated or re-estimated Excess payable by Tenant shall be appropriately adjusted in accordance with the estimation or re-estimation so that, by the end of the calendar year in question, Tenant shall have paid the applicable Excess as estimated or re-estimated by Landlord. Any amounts paid based on such an estimate or re-estimate shall be subject to adjustment pursuant to Section 4.d. when the actual Basic Cost, Snow Removal Cost and Janitorial Cost, as applicable, are available for each calendar year.

c. Basic Cost Definition. For the purposes of this Lease, the term ”Basic Cost” shall mean all expenses and disbursements of every kind (subject to limitations and excluding the exclusions set forth below) which Landlord incurs, pays or becomes obligated to pay in connection with the ownership, operation, and maintenance of the Building (including the associated parking facilities), pro-rated as provided in Sections 4.h. and 4.i., as applicable, determined in accordance with generally accepted federal income tax basis accounting principles consistently applied, including but not limited to the following:

(i) Wages and salaries (including management fees, not to exceed five percent (5%) of gross revenues of the Building for the applicable calendar year) of all employees engaged in the operation, repair, replacement, and maintenance, and security (if reasonably necessary) of the Building, including taxes, insurance and benefits relating thereto pro-rated to the extent such employees are engaged in operation, repair, replacement, maintenance and security of other buildings in addition to the Building (by way of example, the engineer for the Complex bills time to each building in the Complex based on the number of calls and the amount of time spent in each such building within the Complex);

(ii) All supplies and materials used in the operation, maintenance, repair, replacement, and security of the Building;

(iii) Annual cost of all capital improvements made to the Building which although capital in nature can reasonably be expected to reduce the normal operating costs of the Building, as well as all capital improvements made to the Building in order to comply with any law promulgated by any governmental authority not in effect as of the Commencement Date, but only to the extent of the amortized cost of such improvement over the useful economic life of such improvements as determined by Landlord in its reasonable discretion (without regard to the period over which such improvements may be depreciated or amortized for federal income tax purposes);

(iv) Cost of all electricity, water and other utilities for the Building, other than the cost of utilities directly reimbursed to Landlord (i.e., through submeters or comparable devices) or paid directly to utility providers by the Building’s tenants;

(v) Cost of any insurance or insurance related expense applicable to the Building and Landlord’s personal property used in connection therewith;

(vi) All taxes and assessments and governmental charges whether federal, state, county or municipal, and whether they be by taxing or management districts or authorities presently taxing or by others, subsequently created or otherwise, and any other taxes and assessments attributable to the Building (or its operation), and the grounds, parking areas, driveways, and alleys on the Land, including, without limitation, margin taxes, excluding, however, federal and state taxes on income, inheritance taxes, gift taxes, excise taxes, transfer taxes, profit taxes (except as provided in this Lease), late payment charges and levies (collectively, “Taxes”). If the present method of taxation changes so that in lieu of the whole or any part of any Taxes levied on the Land or Building, there is levied on Landlord a capital tax directly on the rents received therefrom (as opposed to real property taxes) or a franchise tax, assessment, or charge based, in whole or in part, upon such rents for the Building, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be included within the term “Taxes” for the purposes hereof;

(vii) Cost of repairs, replacements, and general maintenance of the Building, including repair and general maintenance of the roof, foundation and exterior walls of the Building; and

(viii) Cost of service or maintenance contracts with independent contractors for the operation, maintenance, repair, replacement, or security of the Building (including, without limitation, alarm service, window cleaning, and elevator maintenance).

Notwithstanding anything to the contrary contained herein, the following are expressly excluded from the definition of the term “Basic Cost” (1) capital improvement costs made to the Building, other than capital improvements described in subparagraph (iii) above and except for items which, though capital for accounting purposes, are properly considered maintenance and repair items, such as painting of common areas, replacement of carpet in elevator lobbies, and the like; (2) repair, replacements and general maintenance costs paid by proceeds of insurance or by Tenant or other third parties, and alterations attributable solely to tenants of the Building other than Tenant; (3) interest, amortization or other payments on loans of Landlord; (4) depreciation costs of the Building and Landlord’s personal property; (5) leasing commissions, marketing costs, lease takeover costs, moving costs and other costs incurred solely in order to lease space in the Building; (6) legal fees and expenses, other than those incurred for the general benefit of the Building’s tenants (e.g., Tax disputes); (7) costs for renovating or otherwise improving space for occupants of the Building or vacant space in the Building; (8) federal income taxes imposed on or measured by the income of Landlord from the operation of the Building; (9) rent or other costs for any ground leases affecting the Building; (10) costs for services provided by Landlord’s affiliates to the extent in excess of that which would be incurred in an arms-length transaction; (11) all costs and expenses associated with the replacement of the roof, roof membrane or the two (2) existing thirty-three ton HVAC roof top units serving the Building, provided that Basic Costs shall include the cost of labor incurred to replace individual components of the HVAC units and all other mechanical, electrical and plumbing systems; (12) costs and expenses for items and services for which Tenant reimburses and directly pays to Landlord or directly pays third party providers; (13) the cost of repairs or other work occasioned by fire, windstorm or other insured casualty not by the exercise of eminent domain to the extent of the insurance proceeds or the condemnation awards received therefore; (14) Snow Removal Costs and Janitorial Costs, which shall be invoiced and reconciled separate and apart from Basic Cost; and (15) the cost of Landlord’s Work and the Tenant Improvement Allowance.

d. Annual Cost Statement. Within 120 days after the expiration of each calendar year, or as soon as reasonably practicable but in no event more than one (1) year after each calendar year, Landlord shall furnish to Tenant a statement of Landlord’s itemized actual Basic Cost, Snow Removal Cost and Janitorial Cost and the amount of the applicable Excess (the “Annual Cost Statement”) for the previous year. If Landlord has elected for payments of any Excess to be made monthly in advance based on estimates or re-estimates (as provided in Section 4(b)) and the Annual Cost Statement reveals that Tenant paid more for the applicable Excess in such calendar year to which such statement applies, then Landlord shall promptly credit or reimburse Tenant for such overpayment by Tenant; likewise, if Tenant paid less than the applicable Excess in such calendar year to which the statement applies, then Tenant shall promptly pay Landlord such deficiency. Landlord shall be deemed to have waived any claim it may have to amounts that are not billed to Tenant within two (2) years after the expiration of the calendar year in which they are incurred.

e. Audit. Tenant, at its sole expense, shall have the right, within one hundred twenty (120) days after receiving the Annual Cost Statement for a particular year (“Audit Period”) to review Landlord’s books and records relating to the Basic Cost, Janitorial Cost and Snow Removal Cost for such year if there is a Basic Cost Excess, Janitorial Excess or Snow Removal Excess. Such review shall be conducted only during regular business hours at Landlord’s office and only after Tenant gives Landlord fourteen (14) days prior written notice. Tenant shall deliver to Landlord a copy of the results of such review within the Audit Period if Tenant intends to dispute any Excess. If Landlord and Tenant are not able to agree on the amount of any adjustments to any Excess within thirty (30) days following the delivery of Tenant’s results, Tenant, at its sole cost, may, at its option, hire an independent auditor that is not compensated on a contingency fee basis, or a nationally recognized accounting firm (i.e., a “Top 4” or “Top 5”) which auditor or accounting firm will be mutually and reasonably acceptable to both Landlord and Tenant. The results of such audit shall be binding on the parties. All information obtained

f. Electrical Costs. The Premises are separately metered and Tenant has and will continue to maintain a direct contract with the electricity provider. Tenant shall timely pay the cost of all electricity used by the Building directly to the electricity provider (“Electrical Costs”).

g. Basic Cost Cap. Basic Cost is comprised of “Controllable Costs” and “Non-Controllable Costs.” Controllable Costs are those components of Basic Cost that are not related to Taxes, insurance, snow removal, janitorial services, association fees, utilities, force majeure events, costs not within Landlord’s control and/or collectively-bargained union wages. Non-Controllable Costs are those components of Basic Cost that are not Controllable Costs. Notwithstanding any provision of the Lease to the contrary, for the purpose of calculating Basic Cost each year during the initial Term of the Lease, the items of Controllable Costs shall be deemed not to increase more than five percent (5%) per calendar year (determined on a compounding basis throughout the initial Term of the Lease) for each calendar year from and after the Base Year; provided, however, that no item of Basic Cost other than Controllable Costs shall be subject to the foregoing limitation; and provided further, that the percentage increase shall be determined on a cumulative basis such that if the average increase for all expired calendar years and the next calendar year is less than five percent (5%), then the percentage increase for the next calendar year may exceed five percent (5%) so long as the average increase for all expired calendar years and the next calendar year do not exceed five percent (5%) per calendar year. There shall be no cap on Non-Controllable Costs. For avoidance of doubt, the parties acknowledge and agree that the Snow Removal Costs and Janitorial Costs are not capped.

h. Tenant’s Pro-rata Share of the Complex. Landlord separately contracts for services to the buildings within the Complex on a building by building basis. In the event that a contract applies to the entire Complex, Tenant’s pro-rata share shall be the rentable square footage in the Premises divided by the rentable square footage in the Complex. The Complex currently contains 280,414 rentable square feet.

i. Tenant’s Pro-Rata Share - Taxes. Since the Building and Land are currently on a shared tax parcel with the building known as the 200 building within the Complex, Tenant’s pro-rata share of Taxes shall be the rentable square footage in the Premises divided by the rentable square footage in the 200 building. The Tax parcel currently contains 45,600 rentable square feet.

5. All payments required of Tenant hereunder shall bear interest from the date due (as extended by the notice and cure period set forth in Section 17(a) below) until paid at an interest rate equal to 12% per annum. Alternatively, and in lieu of the foregoing, Landlord may charge Tenant a fee equal to 5% of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a consequence of Tenant’s delinquency. In no event, however, shall the charges permitted under this Section 5 or elsewhere in this Lease, to the extent the same are considered to be interest under applicable law, exceed the maximum lawful rate of interest.

6. Intentionally deleted.

7. a. NO LIABILITY. INTERRUPTION OR MALFUNCTION OF ANY UTILITY OR TELEPHONE SERVICE AND/OR FAILURE TO MAINTAIN TEMPERATURE OR ELECTRICAL CONSTANCY LEVELS SHALL NOT CONSTITUTE A BREACH BY LANDLORD, NOR SHALL SAME BE DEEMED TO CAUSE AN EVICTION (CONSTRUCTIVE OR ACTUAL) OR DISTURBANCE OF TENANT, NOR SHALL SAME RELEASE TENANT FROM ANY OBLIGATION UNDER THIS LEASE, NOR SHALL SAME GRANT TO OR ENTITLE TENANT TO ANY RIGHT TO OFFSET OR RENT ABATEMENT, AND NEITHER LANDLORD NOR LANDLORD’S AGENTS, REPRESENTATIVES OR EMPLOYEES SHALL BE LIABLE FOR DAMAGES (CONSEQUENTIAL OR OTHERWISE) AS A RESULT OF SUCH INTERRUPTION OR MALFUNCTION. MOREOVER, NO SUCH INTERRUPTION OR MALFUNCTION OF SERVICES OR FAILURE TO MAINTAIN TEMPERATURE OR ELECTRICAL CONSTANCY LEVELS, OR THE RESULTS OR EFFECTS THEREOF, SHALL BE CONSTRUED AS AN EVICTION (CONSTRUCTIVE OR ACTUAL) OF TENANT OR AS A BREACH OF ANY IMPLIED WARRANTY OF SUITABILITY, NOR WILL SAME RELIEVE TENANT FROM THE OBLIGATION TO PERFORM ANY COVENANT OR AGREEMENT HEREIN, AND IN NO EVENT SHALL LANDLORD BE LIABLE FOR DAMAGE AS A RESULT OF ANY SUCH INTERRUPTION OR MALFUNCTION OF SERVICES OR FAILURE TO MAINTAIN TEMPERATURE OR ELECTRICAL CONSTANCY LEVELS. The foregoing does not and shall not relieve Landlord of any express repair, maintenance and replacement obligation in this Lease.

b. Excess Utility Use. Tenant shall not install any electrical equipment requiring special wiring or requiring voltage in excess of 110 volts or otherwise exceeding Building capacity unless approved in advance by Landlord. Landlord shall provide the electrical capacity for the Building to Tenant and Tenant will use the electricity in the Building so as not to exceed the capacity of existing feeders and risers to or wiring in the Building (including any changes to the capacity or wiring resulting from Landlord’s Work or the Tenant Improvements). No machinery or equipment shall be permitted that shall cause vibration, noise or disturbance beyond the Premises. Tenant shall not overload any floor or part thereof in the Premises or the Building, bringing in, placing, storing, installing or removing any large or heavy articles, and Landlord may prohibit, or may direct and control the location and size of, safes and all other heavy articles, and may require, at Tenant’s sole cost and expense, supplementary supports of such material and dimensions as Landlord may deem necessary to properly distribute the weight. Except as provided above, this Section 7.b. shall not apply to the Landlord’s Work or the Tenant Improvements.

8. a. Improvements; Alterations. Improvements and alterations to the Premises shall be installed or made at the expense of Tenant only in accordance with plans and specifications which have been previously submitted to and approved in writing by Landlord, which approval shall not be unreasonably withheld with respect to non-structural improvements or alterations, but in Landlord’s sole discretion with regard to structural improvements or alterations and improvements or alterations to the exterior of the Building; provided, however, notwithstanding anything to the contrary contained herein, Tenant shall have the right without Landlord’s approval to make interior, non-structural alterations or improvements (that do not require work to be performed outside of the Building or do not alter the Building systems) in any calendar year that do exceed $25,000 individually or $35,000 in the aggregate during such calendar year. All improvements or alterations performed by or for Tenant shall be performed in good and workmanlike manner quality. Landlord acknowledges and consents to Tenant’s installation of the IT room/AC equipment and supplemental HVAC equipment so long as Tenant provides Landlord with the specifications for such supplemental HVAC equipment, such supplemental HVAC equipment is installed in accordance with any applicable codes and such supplemental HVAC equipment does not exceed Building system capacities. All improvements and alterations made by or for Tenant shall comply with insurance requirements and with applicable law, ordinances, and regulations, including, without limitation and to the extent applicable, laws and regulations regarding removal or alteration of structural or architectural barriers to handicapped or disabled persons (and Tenant shall construct at its expense any alteration required by such laws or regulations, as they may be amended). Tenant shall not paint or install signs, window or exterior door lettering, or advertising media of any type on the outside of the Building without the prior written consent of Landlord, in Landlord’s sole discretion. Obligations and ownership of alterations, additions, or improvements at surrender shall be governed by Section 21. Approval by Landlord of any of Tenant’s drawings and plans and specifications prepared in connection with any improvements in the Premises shall not constitute a representation or warranty of Landlord as to the adequacy or sufficiency of such drawings, plans and specifications, or the improvements to which they relate, for any use, purpose, or condition, but such approval shall merely be the consent of Landlord as required hereunder. Notwithstanding anything in this Lease to the contrary, Tenant shall be responsible for the cost of all work required to comply with the retrofit requirements of the Americans with Disabilities Act of 1990, and all rules, regulations, and guidelines promulgated thereunder, as the same may be amended from time to time, necessitated by any installations, additions, or alterations made in or to the Premises at the request of or by Tenant or by Tenant’s use of the Premises (other than retrofit work whose cost has been particularly identified as being payable by Landlord in an instrument signed by Landlord and Tenant), regardless of whether such cost is incurred in connection with retrofit work required in the Premises or in other areas of the Building. This Section 8.a. shall not apply to the Tenant Improvements which shall be governed by and paid for as provided in Exhibit H-1 and H-2.

b. Repairs; Maintenance. Tenant shall maintain the Premises in a clean, safe, operable, attractive condition, and shall not permit or allow to remain any waste or damage to any portion of the Premises. Tenant shall repair or replace, subject to Landlord’s direction and supervision, any damage to the Premises or Land caused by Tenant or Tenant’s agents, employees or representatives. If Tenant fails to make such repairs or replacements (a) immediately, if there is an emergency situation, or (b) within

c. Performance of Work. All work described in this Section 8 shall be performed only by Landlord or by contractors and subcontractors approved in writing by Landlord, which consent shall not be unreasonably withheld or delayed; provided, however, Landlord may require Tenant to use Landlord’s third-party contractor if such alteration, physical addition or improvement affects any systems, warranties or structural portions of the Premises or the Building so long as Landlord’s third-party contractor’s cost is not materially higher than the price of an arms-length contractor. If Landlord’s third-party contractor’s cost is materially higher, Tenant shall notify Landlord and the parties shall reasonably cooperate to agree on a solution to insure the warranties remain in effect. Notwithstanding anything contained herein to the contrary, Tenant shall not be obligated to obtain Landlord’s approval for any contractor performing improvements or alterations for which Tenant is not obligated to obtain Landlord’s consent, but must give Landlord (or its Complex representative/manager) prior notice of the performance of the improvements and alterations and Landlord must be named as an additional insured on such contractor’s insurance policy. The party engaging the contractors and subcontractors shall cause the contractors and subcontractors to add Landlord and Tenant as an additional insured on such contractor’s insurance. All such work shall be performed in accordance with all legal requirements and in a good and workmanlike manner so as not to damage the Premises, the primary structure or structural qualities of the Building, or plumbing, electrical lines, or other utility transmission facility. All such work which may affect the HVAC, electrical system, or plumbing must be approved by the Building’s engineer of record.

d. Mechanic’s Liens. Tenant shall not permit any mechanic’s liens to be filed against the Premises or the Building for any work performed, materials furnished, or obligation incurred by or at the request of Tenant. If such a lien is filed, then Tenant shall, within ten (10) days after Landlord has delivered notice of the filing to Tenant, either pay the amount of the lien or diligently contest such lien and deliver to Landlord a bond or other security reasonably satisfactory to Landlord. If Tenant fails to timely take either such action, then Landlord may pay the lien claim without inquiry as to the validity thereof, and any amounts so paid, including expenses and interest, shall be paid by Tenant to Landlord within ten (10) days after Landlord has delivered to Tenant an invoice therefor and reasonable evidence of such payment.

e. Mandatory Roof Replacement. Landlord shall replace the roof of the Building at Landlord’s sole cost and expense on or before the earlier to occur of (a) the end of the fifth (5^th) year following the Commencement Date, or (b) a commercially reasonable period of time after the Roof Replacement Condition is satisfied. The “Roof Replacement Condition” shall occur when the costs incurred during the Term to maintain and repair the roof of the Building, including parts and labor, exceed $30,000.00, excluding any damage caused by Tenant. Landlord acknowledges and agrees that the $5,760.00 that has been budgeted for repair and maintenance of the roof during calendar year 2017 shall be applied to and included in the calculation of the Roof Replacement Condition.

f. Mandatory HVAC Replacement. Landlord shall replace the two (2) existing thirty-three ton HVAC roof top units serving the Building (each an “Existing HVAC Unit” and collectively, the “Existing HVAC Units”) at Landlord’s sole cost and expense on or before the end of the fifth (5^th) year following the Commencement Date; provided, however, if the HVAC Replacement Condition for an Existing HVAC Unit is satisfied before the end of the fifth (5^th) year following the Commencement Date, then Landlord shall replace such Existing HVAC Unit within a commercially reasonable period of time after the HVAC Replacement Condition is satisfied for such Existing HVAC Unit. The “HVAC Replacement Condition” shall occur when the costs incurred during the Term to maintain and repair an Existing HVAC Unit, including parts and labor, exceeds $35,000.00 per unit, excluding damage caused by Tenant. For the avoidance of doubt, the occurrence of the HVAC Replacement Condition with respect to one (1) of the Existing HVAC Units shall not obligate Landlord to replace the Existing HVAC Unit for which the HVAC Replacement Condition has not occurred.

g. Landlord’s Repair and Maintenance. Subject to reimbursement by Tenant as provided in this Lease, in addition to Sections 8.e. and 8.f., Landlord, throughout the Term of this Lease, shall, except to the extent the damage is caused by Tenant or its employees, agents, or representatives: (i) maintain and make all necessary repairs replacements to the structure, footings, foundations, structural steel columns and girders forming a part of the Building; (ii) maintain, repair and replace all HVAC Building systems (except as provided in Section 8.h. below), plumbing, electric and other systems serving the Building, and (iii) maintain and make all necessary repairs and replacements to the Building outside of the Premises and to any Common Areas (including Snow Removal), and (iv) provide janitorial services for the Premises Monday through Friday of each week (excluding all holidays observed in the Commonwealth of Pennsylvania) in accordance with guidelines agreed to by the parties unless Tenant has elected to obtain its own janitorial service as provided in Section 8.i. The term “Common Areas” is defined as all areas and facilities outside the Premises and within the exterior boundary line of the Complex that are designated by Landlord from time to time for the general non-exclusive use of Landlord, Tenant and Tenant’s respective employees, suppliers, customers and invitees, including, but not limited to, common entrances, parking areas, loading and unloading areas, roadways and sidewalks.

h. Supplemental HVAC. Except for the Tenant Improvements, Tenant shall be liable, at its sole cost and expense, for installing maintaining and replacing all supplemental air conditioning units (excluding the Existing HVAC Units) or other supplemental equipment in the Premises necessary for Tenant’s operation of its business.

i. Janitorial Services. Notwithstanding anything to the contrary contained in this Lease, Tenant may elect to perform its own janitorial services within the interior of the Premises at any point during the Term provided that the scope of services, products and janitorial contractor are all approved by Landlord, such approval not to be unreasonably withheld. If Tenant elects to perform such services, Tenant agrees to provide Landlord with at least one hundred twenty (120) days advance written notice as to a date when Tenant will begin such service. Upon the commencement of such service, Tenant shall not be obligated to pay Landlord the Janitorial Excess.

j. Landlord’s Work and Tenant Improvements. Landlord’s Work and Tenant Improvements shall be governed by Exhibit H-1 and H-2, respectively.

9. Tenant shall use the Premises only for the Permitted Use and shall comply with all laws, orders, rules, and regulations relating to the use, condition, and occupancy of the Premises. The Premises shall not be used for any use which is disreputable or creates extraordinary fire hazards or results in an increased rate of insurance on the Building or its contents or the storage of any hazardous materials or substances. If, because of Tenant’s acts, Landlord’s rate of insurance on the Building or its contents increases, Tenant shall pay to Landlord the amount of such increase on demand. Tenant shall conduct its business and control its agents, employees, and invitees in such a manner as not to create any nuisance or interfere with other tenants or Landlord in its management of the Building. Tenant shall adopt and implement the following guidelines to avoid developing excessive moisture or mold growth: (a) to report any maintenance problems involving water, moist conditions, or mold to the Landlord promptly and conduct its required activities in a manner which prevents unusual moisture conditions or mold growth; (b) to not block or inhibit the flow of return or make-up into the HVAC system; (c) to maintain the suite at a consistent temperature and humidity level to prevent mold, mildew or moisture conditions and otherwise in accordance with the Landlord’s reasonable instructions; (d) to keep the Premises clean, especially in bathrooms, kitchens, janitorial spaces and other spaces with running water, to remove mildew and prevent or correct moist conditions; and (e) to maintain water in all drain traps at all times. Tenant agrees to promptly notify Landlord if Tenant observes mold/mildew and/or moisture conditions (from any source, including leaks) and allow Landlord to evaluate and make recommendations.

10. a. Transfers; Consent. Except for a Transfer to an Affiliate as provided in Section 10.f., Tenant shall not, without the prior written consent of Landlord (which Landlord agrees will not be unreasonably withheld), (i) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (ii) permit any other entity to become Tenant hereunder by merger, consolidation, or other reorganization, (iii) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as

b. Standards for Approval. It shall be reasonable for Landlord to withhold its consent to any Transfer if (i) there is an Event of Default at the time of the Transfer request or anytime thereafter, but prior to the Transfer, (ii) the financial responsibility (including, without limitation, the fact that the proposed assignee or sublessee is less able financially to pay the Rent under this Lease as and when they are due and payable), nature of business, and character of the proposed transferee are not all reasonably satisfactory to Landlord, (iii) in the reasonable judgment of Landlord the purpose for which the transferee intends to use the Premises (or a portion thereof) is not in keeping with Landlord’s standards for the Building or would impose a burden on the parking facilities, elevators, common areas or utilities that is greater than the burden imposed by Tenant, (iv) the proposed transferee is a government entity or quasi governmental entity or agency, (v) the proposed sublease or assignment is for less than the entire Premises or for less than the remaining Term of the Lease, (vi) the Basic Rental payable by the proposed transferee is less than the greater of: (x) the then prevailing fair market rental rate as reasonably determined by Landlord, or (y) the Basic Rental payable by Tenant under the Lease and/or (vii) the Transfer would cause Landlord to be in violation of any of its obligations under another lease or agreement to which Landlord is a party. The foregoing shall not exclude any other reasonable basis for Landlord to withhold its consent. Landlord shall have no liability for damages to Tenant or to any proposed transferee, and Tenant shall not be permitted to terminate this Lease, if it is adjudicated that Landlord’s consent has been unreasonably withheld and such unreasonable withholding of consent constitutes a breach of this Lease or other duty to Tenant, the proposed transferee or any other person on the part of Landlord. In such event, Tenant’s sole remedy shall be to have the proposed Transfer declared valid as if Landlord’s consent had been given.

c. Leveraged Buyout. The involvement by Tenant or its assets in any transaction, or series of transactions (by way of merger, sale, acquisition, financing, refinancing, transfer, leveraged buy-out or otherwise) whether or not a formal assignment or hypothecation of this Lease or Tenant’s assets occurs, which results or will result in Tenant’s Net Worth (as hereinafter defined) being reduced to below $10,000,000, shall be considered to be an assignment of this Lease by Tenant to which Landlord may reasonably withhold consent.

d. Cancellation. Landlord may, within thirty (30) days after submission of Tenant’s written request for Landlord’s consent to a Transfer, cancel this Lease (or, as to a subletting or assignment, cancel as to the portion of the Premises proposed to be sublet or assigned) as of the date the proposed Transfer was to be effective. If Landlord cancels this Lease as to any portion of the Premises, then (i) this Lease shall cease for such portion of the Premises, (ii) Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer and upon such payment Tenant shall be released from any liability related to the portion of the Premises to which the Lease is no longer effective, and (iii) all Rent due from Tenant to Landlord shall be adjusted to reflect the reduction in the size of the Premises. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant.

e. Additional Compensation. Tenant shall pay to Landlord, immediately upon receipt thereof, 50% of all compensation received by Tenant for a Transfer that exceeds (i) the Basic Rental, plus (ii) Tenant’s share of Excess allocable to the portion of the Premises covered thereby, plus (iii) all costs incurred by Tenant related to such Transfer, including but not limited to, brokerage commissions, alteration and improvement costs for such transferee, reasonable attorney’s fees and credits or abatements given to the transferee.

f. Affiliate Transfers. Notwithstanding anything to the contrary set forth herein, Tenant shall be permitted to assign this Lease, or sublet all or a portion of the Premises, to an Affiliate without the prior consent of Landlord, if all of the following conditions are first satisfied: (a) Tenant shall give Landlord at least thirty (30) days prior written notice of such assignment or subletting; (b) no Event of Default has occurred and is continuing under this Lease; (c) a fully executed copy of such assignment or sublease, the assumption of this Lease by the assignee or acceptance of the sublease by the sublessee, or a copy of the merger, consolidation or stock purchase agreement, as applicable, and such other information regarding the assignment or sublease as Landlord may reasonably request, shall have been delivered to Landlord; (d) the Premises shall continue to be operated solely for the use specified in this Lease; (e) Tenant shall pay all costs reasonably incurred by Landlord in connection with such assignment or subletting, including, without limitation, attorneys’ fees, not to exceed $5,000; and (f) the Affiliate remains an Affiliate of Tenant during the Term of this Lease; and (g) the combined Net Worth of the Affiliate and Tenant at the time of such assignment or subletting is equal to or greater than $10,000,000. As used herein, the term “Affiliate” shall mean an entity which (i) directly or indirectly controls the subject party, (ii) is under the direct or indirect control of the subject party, (iii) is under common direct or indirect control with the subject party, (iv) with which the subject party is merged or consolidated, or (v) which acquires all or substantially all of the subject party’s assets or stock. Control shall mean ownership of fifty-one percent (51%) or more of the voting securities or rights of the controlled entity. Tenant acknowledges and agrees (and agrees at the time of such assignment or subletting to confirm) that in each instance described above, Tenant shall remain liable for the performance of the terms and conditions of this Lease despite such assignment or subletting. “Net Worth” of Tenant as described in this Lease shall mean the net worth of Tenant determined using audited financial statements prepared using generally accepted accounting principles consistently applied by an independent firm of certified public accountants engaged by Tenant.

11. a. Insurance. Tenant shall obtain and keep in force during the Term of this Lease a commercial general liability policy of insurance with coverages acceptable to Landlord, in Landlord’s reasonable discretion based on buildings similar to the Building and uses similar to the Permitted Use, which protects Tenant and Landlord (as an additional insured) against claims for bodily injury, personal injury and property damage based upon, involving or arising out of the ownership, use, occupancy or maintenance of the Premises and all areas appurtenant thereto. Such insurance shall be on an occurrence basis providing single limit coverage in an amount not less than $3,000,000 per occurrence with an “Additional Insured-Managers and Landlords of Premises Endorsement”. The policy shall not contain any intra-insured exclusions as between insured persons or organizations, but shall include coverage for liability assumed under this Lease as an “insured contract” for the performance of Tenant’s indemnity obligations under this Lease. Tenant shall obtain and keep in force during the Term of this Lease “all risk” extended coverage property insurance with coverages acceptable to Landlord, in Landlord’s reasonable discretion based on buildings similar to the Building and uses similar to the Permitted Use. Said insurance shall be written on a one hundred percent (100%) replacement cost basis on Tenant’s personal property, all tenant improvements installed at the Premises by Landlord or Tenant, Tenant’s trade fixtures

b. Waiver; No Subrogation. Landlord shall not be liable to Tenant or Tenant’s employees, agents, contractors, invitees, subtenants, assignees or those claiming by, through, or under Tenant for any sickness or injury to or death of any person or persons or the damage to or theft, destruction, loss, or loss of use of any personal property (each a “Loss”) caused by (i) any condition in the Premises (including mold, mildew and other moisture conditions), (ii) theft, vandalism or criminal acts that occur in the Premises, (iii) any acts or omissions of third parties in the Premises, (iv) Landlord performing repairs or alterations in the Premises or (v) Landlord’s failure to make repairs in the Premises, except the case of each of the foregoing if such Loss is caused by Landlord’s or its representatives, employees or agents gross negligence or misconduct. Landlord and Tenant each waives any claim it might have against the other for any damage to or theft, destruction, loss, or loss of use of any property, to the extent the same is insured against under any insurance policy that covers the Building, the Premises, Landlord’s or Tenant’s fixtures, personal property, leasehold improvements, or business, or, in the case of Tenant’s waiver, is required to be insured against under the terms hereof, REGARDLESS OF WHETHER THE NEGLIGENCE OR FAULT OF THE OTHER PARTY CAUSED SUCH LOSS; however, Landlord’s waiver shall not include any deductible on insurance policies carried by Landlord (which shall be part of Basic Cost). Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier’s rights of recovery under subrogation or otherwise against the other party.

c. INDEMNITY BY TENANT. EXCEPT TO THE EXTENT CAUSED BY THE WILLFUL MISCONDUCT OR GROSS NEGLIGENCE OF LANDLORD OR ITS REPRESENTATIVES, EMPLOYEES OR AGENTS, AND SUBJECT TO SECTION 11.B., TENANT SHALL DEFEND, INDEMNIFY, AND HOLD HARMLESS LANDLORD AND ITS REPRESENTATIVES, EMPLOYEES AND AGENTS FROM AND AGAINST ALL CLAIMS, DEMANDS, LIABILITIES, CAUSES OF ACTION, SUITS, JUDGMENTS, AND EXPENSES (INCLUDING

d. INDEMNITY BY LANDLORD. SUBJECT TO SECTION 11.B, SECTION 26.B. AND THE TERMS AND CONDITIONS OF THIS LEASE, LANDLORD SHALL INDEMNIFY, DEFEND AND HOLD HARMLESS TENANT AND ITS OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DEMANDS, LIABILITIES, CAUSES OF ACTION, SUITS, JUDGMENTS, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS’ FEES), FOR DAMAGE TO PERSON (INCLUDING DEATH OR INJURY) OR PROPERTY OCCURRING IN THE COMMON AREAS TO THE EXTENT ITS ADJUDICATED THAT SUCH LOSS WAS CAUSED BY THE NEGLIGENCE OR WILLFUL MISCONDUCT OF LANDLORD OR ANY OF LANDLORD’S REPRESENTATIVES, EMPLOYEES OR AGENTS.

12. a. Subordination. This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument (a “Mortgage”), or any ground lease, master lease, or primary lease (a “Primary Lease”), that now or hereafter covers all or any part of the Premises (the mortgagee under any Mortgage or the lessor under any Primary Lease is referred to herein as “Landlord’s Mortgagee”); provided that Tenant’s agreement in this Section 12.a. is conditioned on any existing or future Landlord’s Mortgagee recognizing the validity of this Lease and Tenant’s right of possession and not disturbing Tenant’s occupancy (collectively, the “Non-Disturbance Condition”). So long as the Non-Disturbance Condition is satisfied, Landlord’s Mortgagee may at any time, without notice to or consent of Tenant, elect to subordinate any such Mortgage or Primary Lease to this Lease.

b. Attornment. So long as the Non-Disturbance Condition is satisfied, Tenant shall attorn to any party succeeding to Landlord’s interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon such party’s request, and shall execute such agreements confirming such attornment as such party may reasonably request.

c. Notice to Landlord’s Mortgagee. Tenant shall not seek to enforce any remedy it may have for any default on the part of the Landlord without first giving written notice by certified mail, return receipt requested, specifying the default in reasonable detail, to any Landlord’s Mortgagee whose address has been given to Tenant, and affording such Landlord’s Mortgagee a reasonable opportunity to perform Landlord’s obligations hereunder.

d. SNDA. As of the Commencement Date, Landlord represents and warrants that there is no Mortgage or Primary Lease encumbering the Building or the Land. In the event Landlord encumbers the Building or the Land with a Mortgage or Primary Lease, Tenant shall have the right to request from Landlord, in writing, that Landlord use commercially reasonable efforts to obtain a subordination and non-disturbance agreement (“SNDA”) from Landlord’s Mortgagee on Landlord’s Mortgagee’s standard form which must provide that (i) so long as Tenant has not committed an Event of Default under the Lease, upon Landlord’s Mortgagee foreclosure of the Premises or termination of the Primary Lease, as applicable, Mortgagee shall not disturb Tenant’s possession or occupancy under Lease and Tenant shall attorn to said Landlord’s Mortgagee, (ii) Landlord’s Mortgagee shall be bound by the Lease and all amendments thereto entered into on or before the date of the SNDA, and (iii) provided Tenant gives Landlord’s Mortgagee written notice of any default by Landlord under the Lease, Landlord’s Mortgagee shall have a reasonable opportunity to perform Landlord’s obligations after the date of such notice. In such case, if Landlord’s Mortgagee denies the SNDA request or does not respond, Landlord shall have no liability for such failure and the terms and conditions of this Section 12 shall continue to apply. Any fee associated therewith shall be at Tenant’s sole cost and expense and Landlord’s request shall be conditioned upon Tenant’s remittance of said fee.

13. Tenant shall comply with the rules and regulations of the Building which are attached hereto as Exhibit B. Landlord may, from time to time, change such rules and regulations for the safety, care, or cleanliness of the Building and related facilities, provided that such changes are applicable to all tenants of the Building, will not unreasonably interfere with Tenant’s use of the Premises and are provided to Tenant in writing. Tenant shall be responsible for the compliance with such rules and regulations by its employees, agents, and invitees.

14. a. Taking - Landlord’s and Tenant’s Rights. If any part of the Building is taken by right of eminent domain or conveyed in lieu thereof (a “Taking”), and such Taking prevents Tenant from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking, then Landlord may, at its expense, relocate Tenant to office space reasonably comparable to the Premises, provided that Landlord notifies Tenant of its intention to do so within sixty (60) days after the Taking. Such relocation may be for a portion of the remaining Term or the entire Term. Landlord shall complete any such relocation within ninety (90) days after Landlord has notified Tenant of its intention to relocate Tenant. If Landlord does not elect to relocate Tenant following such Taking, then Tenant may terminate this Lease as of the date of such Taking by giving written notice to Landlord within ninety (90) days after the Taking, Rent shall be apportioned as of the date of such Taking and the parties shall have no further obligations under the Lease except for provisions that expressly survive termination. If Landlord does not relocate Tenant and Tenant does not terminate this Lease or if such Taking does not prevent Tenant from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such

b. Taking - Landlord’s Rights. If any material portion, but less than all, of the Building becomes subject to a Taking, or if Landlord is required to pay any of the proceeds received for a Taking to Landlord’s Mortgagee, then this Lease, at the option of Landlord, exercised by written notice to Tenant within ninety (90) days after such Taking, shall terminate and Rent shall be apportioned as of the date of such Taking. If Landlord does not so terminate this Lease then, subject to the rights of Landlord and Tenant in Section 14.a., this Lease will continue, but if any portion of the Premises has been taken, Rent shall abate as provided in the last sentence of Section 14.a.

c. Award. If any Taking occurs, then Landlord shall receive the entire award or other compensation for the Land, the Building, and other improvements taken, and Tenant may separately pursue a claim against the condemnor for the value of Tenant’s personal property which Tenant is entitled to remove under this Lease, moving costs, loss of business, and other claims it may have.

15. a. Repair Estimate. If the Premises or the Building are damaged by fire or other casualty or in the event the Premises become untenantable due to the existence of Hazardous Materials not brought upon, stored or released or produced by Tenant in violation of Environmental Requirements, as defined below (each event being deemed a “Damage Event”), Landlord shall, within sixty (60) days after such Damage Event, deliver to Tenant a good faith estimate (the “Damage Notice”) of the time needed to repair the damage caused by such Damage Event.

b. Landlord’s and Tenant’s Rights. If a material portion of the Premises or the Building is damaged by a Damage Event such that Tenant is prevented from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Damage Event and Landlord estimates that the damage caused thereby cannot be repaired within two hundred seventy (270) days after the Damage Event, then Landlord may, at its expense, relocate Tenant to office space reasonably comparable to the Premises, provided that Landlord notifies Tenant of its intention to do so in the Damage Notice. Such relocation may be for a portion of the remaining Term or the entire Term. Landlord shall complete any such relocation within ninety (90) days after Landlord has delivered the Damage Notice to Tenant. If Landlord does not elect to relocate Tenant following such Damage Event, then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within thirty (30) days after the Damage Notice has been delivered to Tenant. If Landlord does not relocate Tenant and Tenant does not terminate this Lease, then (subject to Landlord’s rights under Section 15.c.) Landlord shall repair the Building or the Premises, as the case may be, as provided below, and Rent for the portion of the Premises rendered untenantable by the damage shall be abated on a proportionate basis from the date of damage until the completion of the repair, unless Tenant intentionally caused such damage, in which case, Tenant shall continue to pay Rent without abatement.

c. Landlord’s Rights. If a Damage Event damages a material portion of the Building, and Landlord makes a good faith determination that restoring the Premises would be uneconomical, or if Landlord is required to pay any insurance proceeds arising out of the Damage Event to Landlord’s Mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within sixty (60) days after the Damage Notice has been delivered to Tenant, and all Rent shall be abated as of the date of the Damage Event so long as Tenant did not intentionally cause Damage Event.

d. Repair Obligation. If neither party elects to terminate this Lease following a Damage Event, then Landlord shall, within a reasonable time after such Damage Event, commence to repair the Building and the Premises and shall proceed with reasonable diligence to restore the Building and Premises to substantially the same condition as they existed immediately before such Damage Event; however, Landlord shall not be required to repair or replace any part of the furniture, equipment, fixtures, and other improvements which may have been placed by, or at the request of, Tenant or other occupants in the Building or the Premises, and Landlord’s obligation to repair or restore the Building or Premises shall be limited to the extent of the insurance proceeds actually received by Landlord for the Damage Event in question.

e. Last Six (6) Months of the Lease. Without limiting Landlord’s rights under this Section 15, in the event the Premises shall, in Landlord’s reasonable judgment, be substantially damaged due to Damage Event during the last six (6) months of the Term of this Lease, Tenant did not intentionally cause said Damage Event and Tenant has not extended the Term of the Lease, Landlord or Tenant may elect to terminate this Lease effective upon giving notice of such election, in writing, to the other party within thirty (30) days after the occurrence of the Damage Event.

f. Timing of Restoration. If Landlord undertakes restoration of the Premises and Building pursuant to this Section 15, Landlord shall use reasonable diligence in completing such repairs, but if Landlord fails to substantially complete the same within two hundred seventy (270) days from the date of the Damage Event, subject to force majeure events, Tenant may, at its option and as Tenant’s sole remedy, terminate this Lease by written notice given to Landlord within ten (10) days following the expiration of the applicable 270-day period, whereupon both parties shall be released from all further obligations and liability hereunder, other than those expressly surviving termination.

16. Tenant shall be liable for all taxes levied or assessed against personal property, furniture, or fixtures placed by Tenant in the Premises. If any taxes for which Tenant is liable (as described in the foregoing sentence) are levied or assessed against Landlord or Landlord’s property and Landlord elects to pay the same, or if the assessed value of Landlord’s property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, then Tenant shall pay to Landlord, upon demand after written notice to Tenant including evidence of such increase being related to Tenant’s personal property, furniture or fixtures, that part of such taxes for which Tenant is primarily liable hereunder.

17. Each of the following occurrences shall constitute an “Event of Default”:

a. Tenant’s failure to pay Rent, or any other sums due from Tenant to Landlord under the Lease when due and the continuance of such failure for a period of five (5) business days; provided, that, in addition to the foregoing cure period, Landlord shall give Tenant written notice of the first failure by Tenant to pay Rent or other sums due to Landlord in any consecutive 12-months of the Term of this Lease and if Tenant fails to cure the same within five (5) business days following the date of Landlord’s notice, such failure shall be an Event of Default;

b. Tenant’s failure to perform, comply with, or observe any other agreement or obligation of Tenant under this Lease and the continuance of such failure for a period of thirty (30) days following the date of written notice from Landlord or if such failure cannot be reasonably cured within such 30-day period, such extended period, as shall reasonably be expected to cure the same (but in no event more than 90 days from the date of Landlord’s written notice to Tenant of an Event of Default), provided Tenant commences the cure within the 30-day period and is diligently pursuing the same to completion;

c. The filing of a petition by or against Tenant (the term “Tenant” shall include, for the purpose of this Section 17.c., any guarantor of the Tenant’s obligations hereunder) (i) in any bankruptcy or other insolvency proceeding; (ii) seeking any relief under any state or federal debtor relief law; (iii) for the appointment of a liquidator or receiver for all or substantially all of Tenant’s property or for Tenant’s interest in this Lease and such appointment is not vacated within sixty (60) days after appointment; or (iv) for the reorganization or modification of Tenant’s capital structure; and

d. The admission by Tenant in writing that it cannot meet its obligations as they become due or the making by Tenant of an assignment for the benefit of its creditors.

For avoidance of doubt, the defined term “Event of Default” includes any applicable notice and cure periods and if Tenant cures the failure or action within the notice and cure period, then such failure or action shall not be an Event of Default.

18. Upon any Event of Default, Landlord may, in addition to all other rights and remedies afforded Landlord hereunder or by law or equity, take any of the following actions:

a. Terminate this Lease by giving Tenant written notice thereof, in which event, Tenant shall pay to Landlord the sum of (i) all Rent accrued hereunder through the date of termination, (ii) all amounts due under Section 19.a., and (iii) an amount equal to (A) the total Rent that Tenant would have been required to pay for the remainder of the then-current Term discounted to present value at a per annum rate equal to the “Prime Rate” as published on the date this Lease is terminated by The Wall Street Journal, Southeast Edition, in its listing of “Money Rates”, minus (B) the then present fair rental value of the Premises for such period, similarly discounted; or

b. Terminate Tenant’s right to possession of the Premises without terminating this Lease by giving written notice thereof to Tenant, in which event Tenant shall pay to Landlord (i) all Rent and other amounts accrued hereunder to the date of termination of possession, (ii) all amounts due from time to time under Section 19.a., and (iii) all Rent and other sums required hereunder to be paid by Tenant during the remainder of the then-current Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during such period. Landlord shall use commercially reasonable efforts to relet the Premises on such terms and conditions as Landlord in its sole discretion may determine (including a term different from the Term, rental concessions, and alterations to, and improvement of, the Premises). Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure to relet the Premises or to collect rent due for such reletting, provided that Landlord uses commercially reasonable efforts to relet and collect rent as provided in Section 19.c. below. Tenant shall not be entitled to the excess of any consideration obtained by reletting over the Rent due hereunder. Reentry by Landlord in the Premises shall not affect Tenant’s obligations hereunder for the unexpired then-current Term;

c. Additionally, without notice, Landlord may alter locks or other security devices at the Premises to deprive Tenant of access thereto, and Landlord shall not be required to provide a new key or right of access to Tenant.

19. a. Payment by Tenant. Upon any Event of Default, Tenant shall pay to Landlord all reasonable costs incurred by Landlord (including court costs and reasonable attorneys’ fees and expenses) in (i) obtaining possession of the Premises, (ii) removing and storing Tenant’s or any other occupant’s property, (iii) repairing, restoring, altering, remodeling, or otherwise putting the Premises into condition acceptable to a new tenant, (iv) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part of the Premises (including standard brokerage commissions, cost of tenant finish work, and other costs incidental to such reletting), (v) performing Tenant’s obligations which Tenant failed to perform, and (vi) enforcing, or advising Landlord of, its rights, remedies, and recourses arising out of the Event of Default.

b. No Waiver. Landlord’s acceptance of Rent following an Event of Default shall not waive Landlord’s rights regarding such Event of Default. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord’s rights regarding any future violation of such term or violation of any other term.

c. Reletting. Tenant acknowledges that Landlord has entered into this Lease in reliance upon, among other matters, Tenant’s agreement and continuing obligation to pay all Rent due throughout the Term. Upon Landlord’s termination of this Lease and Tenant’s possession after the occurrence of an Event of Default, to the extent required under then applicable law, Landlord agrees to use commercially reasonable efforts to relet the Premises; provided, however, in connection therewith, Tenant agrees that Landlord has no obligation to: (i) relet the Premises (A) at a rental rate or otherwise on terms below market, as then determined by Landlord in its sole discretion; (B) to any entity not satisfying Landlord’s then standard financial credit risk criteria; (C) for a use (1) not consistent with Tenant’s use prior to the Event of Default; (2) which would violate then applicable law or any restrictive covenant or other lease affecting the Building; (3) which would impose a greater burden upon the Building’s parking, HVAC or other facilities; and/or (4) which would involve any use of Hazardous Materials; (ii) divide the Premises, install new demising walls or otherwise reconfigure the Premises to make same more marketable; and/or (iii) relet the Premises, if to do so, Landlord would be required to alter other portions of the Building, make ADA-type modifications or otherwise install or replace any sprinkler, security, safety, HVAC or other Building operating systems.

20. Intentionally deleted.

21. No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless the same is made in writing and signed by Landlord. At the expiration or termination of this Lease, Tenant shall deliver to Landlord the Premises with all improvements located thereon broom clean and in good repair and condition, reasonable wear and tear (and condemnation and fire or other casualty damage (including a Damage Event) not intentionally caused by Tenant, as to which Sections 14 and 15 shall control) excepted, and shall deliver to Landlord all keys to the Premises. At the time of expiration or termination of this Lease, Tenant shall remove (a) all trade fixtures, equipment, wiring, cabling, furniture and the IT room/AC equipment; and (b) such alterations, additions, improvements performed by or for Tenant, as Landlord may request (unless Landlord at the time of such request for approval agrees in writing that Tenant shall not be required to remove such improvement or alteration upon Lease expiration). Tenant shall repair all damage caused by such removal. Notwithstanding the foregoing, Tenant shall not be obligated to remove the Landlord’s Work or the Tenant Improvements completed in accordance with Exhibit H-1 and H-2, attached hereto, unless with respect to Tenant Improvements, Landlord notifies Tenant otherwise in writing at the time such Tenant Improvements are approved in accordance with Exhibit H-2. All items not so removed shall be deemed to have been abandoned by Tenant and may be appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items. The provisions of this Section 21 shall survive the end of the Term.

22. If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be a tenant at sufferance and, (i) Tenant shall pay, in addition to the other Rent, a daily Basic Rental equal to 150% of the daily Basic Rental payable during the last month of the Term; and (ii) if Tenant holds over for more than thirty (30) days after the end of the Term, in addition to the amount in (i) above, Landlord shall be entitled to pursue consequential damages, if any, resulting from such hold over but only to the extent the consequential damages relate to the period after the first 30 days of the hold over (and not to the first thirty (30) days of the holdover) and, in addition, Landlord may also pursue a confession of judgment solely for possession of the Premises. Landlord acknowledges and agrees that the damages and remedies in this Section 22 are Landlord’s exclusive damages and remedies for a holdover and Landlord shall not be entitled to any other damages or to pursue any other remedies under this Lease, at law, in equity or otherwise. In addition to and without limiting the foregoing, Landlord acknowledges and agrees that the damages and remedies in this Section shall be Landlord’s exclusive damages and remedies if Tenant fails to vacate the Premises at the end of the Term.

23. Provided that the exercise of such rights does not unreasonably interfere with Tenant’s use or occupancy of the Premises, Landlord shall have the following rights (so long as Landlord provides Tenant prior email or oral notice, except in the event of an emergency, in which case, no prior notice is necessary but Landlord shall notify Tenant as soon as reasonably practical):

a. To make inspections and repairs, alterations, additions, changes, or improvements, whether structural or otherwise, in and about the Building, or any part thereof but only to the extent of the rights or obligations of Landlord provided in this Lease; for such purposes, to enter upon the Premises and, during the continuance of any such work, to temporarily close doors, entryways, and corridors in the Building; to temporarily interrupt or suspend Building services and facilities, to temporarily close certain Common Areas for inspections, repairs, alterations, changes or improvements;

b. In the event of an emergency, to take such reasonable measures as Landlord deems necessary for the security of the Building and its occupants;

c. To change the name by which the Building is designated; and

d. To enter the Premises during reasonable business hours and upon reasonable prior written notice to show the Premises to prospective purchasers, lenders, or tenants; provided, however, that Landlord shall only have the right to show the Premises to prospective tenants during the last eighteen (18) months of the Lease.

Notwithstanding anything contained in this Lease to the contrary, Landlord shall not be required to give Tenant notice of any janitorial services provided by Landlord under this Lease that are performed as part of the ordinarily schedule agreed to by the parties. The parties shall cooperate to schedule and implement safety drills for the Building.

24. Intentionally deleted.

25. a. General. Except for such incidental cleaning agents and solutions or maintenance materials used in the ordinary course or materials and goods stored as part of Tenant’s business operations including in connection with any janitorial services (but such use and storage shall be in compliance with all Environmental Requirements), Tenant shall not permit or cause any party to bring any Hazardous Material upon the Premises or store or use any Hazardous Material in or about the Premises without Landlord’s prior written consent. Tenant, at its sole cost and expense, shall operate its business in the Premises in compliance with all Environmental Requirements, and will obtain, comply with, and properly maintain all permits and licenses, or applications required by Environmental Requirements for its operations. The term “Environmental Requirements” means all applicable present and future statutes, regulations, ordinances, rules, codes, or other similar enactments of any governmental authority of agency, and any applicable judicial, administrative or regulatory decrees, judgments, orders, or policies regulating or relating to any Hazardous Materials or pertaining to health, safety, industrial hygiene, or the environmental conditions on, under, or about the Premises or the environment, including, without limitation, the following: the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”); the Resource Conservation and Recovery Act; the Toxic Substances Control Act; the Clean Air Act; the Federal Water Pollution Control Act; the Federal Hazardous Materials Transportation Act; and all state and local counterparts, supplements or additions thereto, and any regulations or policies promulgated or issued thereunder. The term “Hazardous Materials” means and includes petroleum (as defined in CERCLA), asbestos and any substance, material, waste, pollutant, or contaminant listed or defined as hazardous or toxic, under any Environmental Requirements.

b. Indemnity. Tenant shall indemnify, defend, and hold Landlord and its partners, officers, directors, agents and employees harmless from and against any and all losses (including, without limitation, all consequential damages and loss of rental income) claims, demands, actions, suits, damages (including, without limitation, punitive damages owed to third parties), fines, penalties, administrative and judicial proceedings, judgments, settlements, expenses (including, without limitation, reasonable consultant fees, attorneys’ fees, or expert fees) to the extent related to Tenant’s use or operations during the Term or to the extent caused by a breach of the Tenant’s obligations under Section 25.a. by Tenant, its agents, employees or representatives, regardless of whether Tenant had knowledge of such noncompliance; provided, that notwithstanding the foregoing, Tenant shall only be responsible to indemnify as provided above for consequential damages, loss of rental income, punitive damages or any other

c. Assessments. Landlord shall have access to, and a right to perform inspections and tests of, the Premises as it may require to determine Tenant’s compliance with Environmental Requirements and Tenant’s obligations under this Section 25. Access shall be granted to Landlord upon Landlord’s prior written notice to Tenant and at such times so as to minimize, so far as may be reasonable under the circumstances, any disturbance to Tenant’s operations. At the expiration or earlier termination of the Lease, Landlord shall have the right, at its option, to undertake an environmental assessment of the Premises to determine Tenant’s compliance with all Environmental Requirements. All such inspections and tests shall be conducted at Landlord’s expense, unless such inspections or tests definitively reveal that Tenant released the Hazardous Material on or under the Premises or that Tenant has not complied with all Environmental Requirements, in which case Tenant shall immediately, upon demand, reimburse Landlord for the cost of such inspection and tests. Landlord and Tenant agree that Landlord’s receipt of or satisfaction with any environmental assessment in no way waives any rights that Landlord holds against Tenant.

d. Landlord’s Obligations. Landlord shall be responsible, at its expense (and at no cost to Tenant), for the cost of clean up or any other remedial measures for any Hazardous Materials in, on or about the Building or the Land caused by Landlord or its agents, employees or representatives. Any environmental remediation costs that are not caused by Tenant in violation of Environmental Requirements shall not be included in any costs passed through to Tenant (other than any required air quality tests in the Building). Landlord shall defend, indemnify and hold harmless Tenant and its partners, officers, directors, agents and employees from and against any and all losses, claims, actions, damages, liabilities, penalties, and expenses (including all reasonable attorney’s, consultant’s and expert’s fees, expenses and liabilities incurred in defense of any such claim or any action or proceeding brought thereon) to the extent resulting from a proven violation by Landlord or its agents, employees or representatives of any Environmental Requirements impacting the Building or Land.

26. a. Landlord Transfer. Landlord may transfer, in whole or in part, the Building and any of its rights under this Lease. If Landlord assigns its rights under this Lease, then Landlord shall thereby be released from any obligations hereunder occurring after the date of such assignment or transfer.

b. Landlord’s Liability. The liability of Landlord to Tenant for any default by Landlord under the terms of this Lease shall be limited to Tenant’s actual direct, but not consequential, damages therefor and shall be recoverable from the interest of Landlord in the Building and the Land, and Landlord shall not be personally liable for any deficiency. Landlord shall not be in default hereunder and Tenant shall not have any remedy or cause of action unless Landlord fails to perform any of its obligations hereunder within thirty (30) days after written notice from Tenant specifying such failure (unless such performance will, due to the nature of the obligation, require a period of time in excess of thirty (30) days, then after such period of time as is reasonably necessary but in no event longer than ninety (90) days after written notice from Tenant, so long as Landlord commenced the cure of the default in such thirty (30) day period and is diligently pursuing the cure of such default). Except as expressly provided herein, if Landlord is in default hereunder, Tenant’s exclusive remedy shall be an action for damages, and Tenant’s damages shall be limited to Tenant’s actual direct (excluding consequential, special, exemplary and punitive damages) damages therefor.

c. Force Majeure. Other than for Tenant’s monetary obligations under this Lease and obligations of either party which can be cured by the payment of money (e.g., maintaining insurance), whenever a period of time is herein prescribed for action to be taken by either party hereto, such party shall not be liable or responsible for, and there shall be excluded from the computation for any such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, terrorism, bio-terrorism, governmental laws, regulations, or restrictions, or any other causes of any kind whatsoever which are beyond the control of such party.

d. Brokerage. Landlord and Tenant each warrant to the other that it has not dealt with any broker or agent in connection with the negotiation or execution of this Lease except Cushman & Wakefield (“Landlord’s Broker”) and Jones Lang LaSalle (collectively, the “Brokers”). Landlord will pay all commissions due to the Brokers pursuant to one or more separate written agreements. Landlord and Tenant shall each indemnify the other against all costs, expenses, attorneys’ fees, and other liability for commissions or other compensation claimed by any broker or agent claiming the same by, through, or under the indemnifying party; provided, however that Tenant shall have no obligation to indemnify Landlord for any amounts due to the Brokers except to the extent Tenant executes a separate agreement with either Broker after the full execution of this Lease and such separate agreement expressly provides Tenant is responsible to pay a commission thereunder.

e. Estoppel Certificates. From time to time, Tenant shall furnish to any party designated by Landlord, within ten (10) days after Landlord has made a request therefor, a certificate signed by Tenant, to Tenant’s actual knowledge confirming and containing such factual certifications and representations as to this Lease as Landlord may reasonably request subject to exceptions and additional facts provided by Tenant. Within thirty (30) days after receipt of written request by Tenant, Landlord shall execute, acknowledge and deliver to Tenant (or its designee) a written statement certifying to the best of Landlord’s actual knowledge, (i) that this Lease is unmodified and in full force and effect, or is in full force and effect as modified and stating the modifications; (ii) the amount of Basic Rental currently payable by Tenant to Landlord; (iii) the Basic Costs currently payable by Tenant to Landlord; (iv) the date to which Basic Rental and Basic Costs have been paid in advance; (v) the amount of any security deposited with Landlord; and (vi) any other information reasonably requested without investigation or inquiry by Landlord. Any such statement may be relied upon by an investor, purchaser, assignee or lender.

Notice sent by certified mail, postage prepaid, shall be effective three (3) business days after being deposited in the United States Mail; all other notices shall be effective upon delivery to the address of the addressee. The parties hereto may change their addresses by giving notice thereof to the other in conformity with this provision.

g. Severability. If any clause or provision of this Lease is illegal, invalid, or unenforceable under present or future laws, then the remainder of this Lease shall not be affected thereby and in lieu of such clause or provision, there shall be added as a part of this Lease a clause or provision as similar in terms to such illegal, invalid, or unenforceable clause or provision as may be possible and be legal, valid, and enforceable.

h. Amendments; and Binding Effect. This Lease may not be amended except by instrument in writing signed by Landlord and Tenant. No provision of this Lease shall be deemed to have been waived by any party unless such waiver is in writing signed by such party, and no custom or practice which may evolve between the parties in the administration of the terms hereof shall waive or diminish the right of either party to insist upon the performance by the other party in strict accordance with the terms hereof. The terms and conditions contained in this Lease shall inure to the benefit of and be binding upon the parties hereto, and upon their respective successors in interest and legal representatives, except as otherwise herein expressly provided. This Lease is for the sole benefit of Landlord and Tenant, and, other than Landlord’s Mortgagee (subject to and to the extent provided in Section 12), no third party shall be deemed a third party beneficiary hereof.

i. Quiet Enjoyment. Provided there is no Event of Default, Tenant shall peaceably and quietly hold and enjoy the Premises for the Term, without hindrance from Landlord or any party claiming by, through, or under Landlord.

p. Relationship of Parties. This Lease shall create the relationship of landlord and tenant only as between Landlord and Tenant.

q. Confidentiality. Tenant acknowledges and agrees that the terms of this Lease are confidential and constitute proprietary information of Landlord. Disclosure of the terms hereof could adversely affect the ability of Landlord to negotiate other leases with respect to the Building and may impair Landlord’s relationship with other tenants of the Building. Tenant agrees that it and its partners, officers, directors, employees, brokers, and attorneys, if any, shall not disclose the terms and conditions of this Lease to any other person or entity without the prior written consent of Landlord

r. Governing Law. This Lease shall be governed by and construed in accordance with the laws of the Commonwealth of Pennsylvania.

If Tenant is a corporation, trust or partnership, Tenant shall deliver to Landlord, at Landlord’s request, commercially reasonable evidence of such authority.

t. Time of Essence. Time is of the essence with respect to each of the obligations to be performed by Tenant and Landlord under this Lease.

v. No Recording by Tenant. Tenant shall not record in any public records any memorandum or any portion of this Lease.

w. OFAC. As of the date of this Lease, Tenant and its Affiliates are not, and to Tenant’s knowledge, without investigation, its or its Affiliate’s partners, members, shareholders, equity owners, employees, officers, directors, representatives or agents are not, a person or entity with whom U.S. persons or entities are restricted from doing business under regulations of the Office of Foreign Asset Control (“OFAC”) of the Department of the Treasury (including those named on OFAC’s Specially Designated and Blocked Persons List) or under any statute, executive order (including the September 24, 2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism), or other governmental action. For purposes of this Section, the term “Affiliate” does not include items (iv) and (v) of the definition of Affiliate set forth in Section 10.f.

x. Security Measures. Tenant hereby acknowledges that Landlord shall have no obligation whatsoever to provide guard service or other security measures for the benefit of the Premises, Common Areas or the Building, and Landlord shall have no liability to Tenant, its agents, employees, contractors and invitees due to Landlord’s failure to provide such services. The foregoing assumption of risk shall not restrict Tenant’s ability to sue other third parties providing security services to the Complex. Nothing herein contained shall prevent Landlord, at Landlord’s sole option, from implementing security measures for the Complex or any part thereof, in which event the cost thereof (pro-rated for Tenant’s share) shall be included within the definition of Basic Cost.

y. Tenant Access. Landlord represents and warrants to Tenant that Tenant shall have the ability to access to the Premises, at all times, subject to Landlord’s rights under Section 23.a. above.

z. Landlord’s Right to Perform Tenant’s Duties. Upon any Event of Default related to any obligation of Tenant under this Lease, Landlord shall have the right (but not the obligation), to perform such obligation on behalf and at the expense of Tenant without further notice to Tenant, and all reasonable sums expended or reasonable expenses incurred by Landlord in performing such obligation shall be deemed to be Rent under this Lease and shall be due and payable to Landlord within fifteen (15) days after a demand is made by Landlord and reasonable evidence of the costs and expenses are provided to Tenant.

aa. NOTICE OF INDEMNIFICATION. THIS LEASE CONTAINS INDEMNIFICATION PROVISIONS WHICH EACH SHALL EXPRESSLY SURVIVE THE EXPIRATION OR TERMINATION OF THIS LEASE.

bb. Financial Statements. Tenant shall furnish Landlord with true and complete copies of its most recent annual and quarterly financial statements prepared by Tenant or Tenant’s accountants and any other financial information or summaries that Tenant typically provides to its lenders if Landlord requests such information in writing for any sale, transfer or financing related to the Building or Landlord, provided that prior to Tenant providing such information the purchaser, transferee or lender, as applicable, and Landlord shall execute a commercially reasonable confidentiality agreement with Tenant. Tenant represents to Landlord that as of the date of Lease execution, Tenant’s Net Worth (as defined in Section 10) is equal to or greater than $10,000,000.00.

cc. Abatement Personal. If and to the extent that this Lease provides for the abatement of any Rent or other charges due from Tenant under this Lease, including, without limitation, parking charges or storage space charges, any such abatement is personal to the original named Tenant under this Lease and its Affiliates and is not transferable to any assignee of Tenant’s rights under this Lease (other than an Affiliate). If Tenant’s rights are assigned, then, as of the effective date of such assignment, any such abatements that have not occurred shall terminate and be rendered of no force or effect and the Rent or other charges shall be payable going forward at the rate otherwise applicable for such period. In no event shall Tenant, an Affiliate or any assignee or transferee of Tenant be obligated to repay any amount for any abatement that has previously occurred.

dd. NO CONSEQUENTIAL DAMAGES. In no event shall Landlord or Tenant be liable to the other for any special, consequential, indirect, exemplary or punitive damages or for any lost profits or revenues; provided, however, Tenant shall remain liable for all such damages but only to the extent expressly provided in Sections 22 and 25.

ee. Generator. Tenant shall have the right to install an emergency generator, at its option, as more particularly provided in Exhibit I attached hereto.

ff. Counterparts. This Lease may be executed in multiple counterparts each of which is deemed an original but together constitute one and the same instrument. This Lease may be executed by PDF electronically and each party has the right to rely upon said counterpart of this Lease signed by the other party to the same extent as if such party had received an original counterpart. The parties acknowledge and agree that notwithstanding any law or presumption to the contrary, an electronic signature of either party, whether upon this Lease or any related document shall be deemed valid and binding and admissible by either party against the other as if same were an original ink signature. THIS LEASE SHALL BECOME BINDING UPON LANDLORD AND TENANT ONLY WHEN FULLY EXECUTED BY BOTH PARTIES AND WHEN LANDLORD HAS DELIVERED THIS LEASE TO TENANT IN THE MANNER SET FORTH IN THIS SECTION (BY PDF) OR AS PROVIDED IN SECTION 26.f.

Landlord and Tenant are knowledgeable and experienced in commercial transactions and agree that the provisions set forth in this Lease for determining charges, amounts and additional rent payable by Tenant are commercially reasonable and valid even though such methods may not state a precise mathematical formula for determining such charges.

LANDLORD AND TENANT EXPRESSLY DISCLAIM ANY IMPLIED WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANT’S INTENDED COMMERCIAL PURPOSE, AND TENANT’S OBLIGATION TO PAY RENT HEREUNDER IS NOT DEPENDENT UPON THE CONDITION OF THE PREMISES OR THE PERFORMANCE BY LANDLORD OF ITS OBLIGATIONS HEREUNDER, AND, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, TENANT SHALL CONTINUE TO PAY THE RENT, WITHOUT ABATEMENT, SETOFF, DEDUCTION, NOTWITHSTANDING ANY BREACH BY LANDLORD OF ITS DUTIES OR OBLIGATIONS HEREUNDER, WHETHER EXPRESS OR IMPLIED.
