THIS AMENDED AND RESTATED LEASE is made this 29^th day of August, 2012 (the “Effective Date”) between 000 XXXXXXXX XXXXX ASSOCIATES, L.P., a Pennsylvania limited partnership (“Existing Building Landlord”), THE XXXXXX GROUP, a Pennsylvania limited partnership (“Lot 11 Owner”), each with its office at Eagleview Corporate Center, 000 Xxxxxxxxx Xxxxxxxxx, X.X. Xxx 000, Xxxxx, Xxxxxxxxxxxx 00000, and VIROPHARMA INCORPORATED, a Pennsylvania corporation (“Tenant”), with its office at 000 Xxxxxxxx Xxxxx, Xxxxx, Xxxxxxxxxxxx 00000, and amends and restates in its entirety that certain lease between the parties dated March 14, 2008.

BACKGROUND

Existing Building Landlord and Tenant are parties to a certain lease dated March 14, 2008 (the “Original Lease”) pertaining to a building and improvements (the “Existing Building”) constructed by Existing Building Landlord at 000 Xxxxxxxx Xxxxx, Xxxxxxxxx Corporate Center (the “Center”), Upper Uwchlan Township, Xxxxxxx County, Pennsylvania, consisting of 78,264 rentable square feet of space (the “Existing Leased Space”). The Original Lease has an expiration date of April 30, 2016. The Existing Building is located on an 8.628 acre lot known and numbered as Lot 10 (“Lot 10”), which Lot 10 is adjacent to other land consisting of a separately subdivided lot consisting of 14.16 acres more or less assigned lot number 11 on the recorded subdivision plan, and which is the subject of an expansion option granted to Tenant pursuant to Section 46 of the Original Lease, and is referred to herein as “Lot 11”, and which is owned by the Xxx 00 Xxxxx.

Xxxxxxxx Xxxxxxxx Xxxxxxxx, Xxx 00 Owner and Tenant desire to expand the area leased and occupied by Tenant to include, in addition to the Existing Leased Space, an area consisting of an expansion of the Existing Building to include an additional 71,000 square feet, more or less (the “New Leased Space”), a portion of which shall be erected on Lot 10, and a portion of which shall be erected on Lot 11, pursuant to a subdivision plan for which Existing Building Landlord and Lot 11 Owner intend to obtain approval from Upper Uwchlan Township, which subdivision plan shall create a new lot consisting of Lot 10 and Lot 11. Such new Lot is referred to herein as the “Land”, and such expansion of the Existing Building is referred to herein as the “New Building.” Upon issuance of the foregoing subdivision approval, Lot 11 which is to be merged with Lot 10, and the rights and obligations of Lot 11 Owner under this Lease with respect thereto, will be conveyed to Existing Building Landlord. Until such conveyance, any reference in this Lease to “Landlord” shall mean and refer to Existing Building Landlord and Lot 11 Owner; after such conveyance, any reference in this Lease to “Landlord” shall mean and refer only to Existing Building Landlord, and Lot 11 Owner shall have no liability hereunder. Notwithstanding any provision in this Lease to the contrary, Lot 11 Owner’s obligations under this Lease shall be limited to its obligation to cooperate in obtaining the required subdivision approval to annex Lot 11 to Lot 10 and conveying Xxx 00 xx Xxxxxxxx Xxxxxxxx Xxxxxxxx and any references to rights, duties and obligations of Landlord with respect to the Existing Leased Space and Existing Building shall mean and refer only to Existing Building Landlord.

The terms and conditions upon which Tenant shall continue to lease and occupy the Existing Leased Space and New Leased Space (collectively the “Leased Space”) are more fully set forth below.

NOW THEREFORE, Landlord and Tenant, each intending to be legally bound hereby, agree that the Original Lease is amended and restated in its entirety as follows:

LEASED SPACE AND PURPOSE.

(a) Landlord hereby continues to rent to Tenant the Existing Leased Space consisting of the 78,264 square foot Existing Building, and rents to Tenant: (1) the New Leased Space, when and as the New Building is constructed in accordance with the terms and conditions of this Lease, which Existing Building and New Building shall be located on the Land, the newly created lot constituting the Land being shown on the plan attached hereto as Exhibit A, and (2) the interior improvements to be constructed by Landlord in the New Building, together with all fixtures, improvements, additions and other property installed therein as the same may be modified in accordance with the provisions of this Lease. The “Leased Space” for the purposes of this Lease shall include the Existing Leased Space, the New Leased Space when constructed, and all fixtures, improvements, additions and other property installed in the Existing Leased Space as of the date hereof, and all fixtures, improvements, additions and other property installed in the New Leased Space when and as installed by Landlord (other than Tenant’s movable personal property and trade fixtures), together with the right to use, in common with others, the parking lot and all other public portions of the Center. The “Building”, for the purposes of this Lease, shall include the Existing Building and, upon substantial completion of the Core and Shell and Tenant Improvements pursuant to the Work Letter attached hereto as Exhibit B, the New Building.

(b) The Leased Space shall be used and occupied as a general office space, in connection with Tenant’s Business (hereafter defined), which may include the incidental handling of pharmaceutical products and chemicals used in such products and for no other purpose. For purposes hereof, Tenant’s Business shall be deemed to be the development and commercialization of pharmaceutical products.

TERM.

(a) The term of this Lease and Tenant’s obligation to pay rent hereunder shall commence, with respect to the Existing Leased Space, on the date hereof, and with respect to the New Leased Space, upon the date (“Commencement Date”) when Landlord has Substantially Completed the construction of the Core and Shell (as defined in the Work Letter) of the New Building and the Tenant Improvements (as defined in the Work Letter).

(b) “Substantial Completion” or “Substantially Completed” shall mean, with respect to the Core and Shell, completion of the Core and Shell, as established by a statement by the architect who authored the Core and Shell Plans and Specifications that the Core and Shell are substantially completed in accordance with the Core and Shell Plans and Specifications such that

Landlord is able to commence construction of the Tenant Improvements when and as TI Plans are complete and a building permit for the Tenant Improvements has been issued. “Substantial Completion” or “Substantially Completed” shall mean, with respect to the Tenant Improvements, completion of the Tenant Improvements, as established by a statement by the TI Architect that the Tenant Improvements are substantially completed in accordance with the final, approved TI Plans. Substantial Completion shall be deemed to have been achieved even though minor or insubstantial details of construction, mechanical adjustment or decoration remain to be performed, the non-completion of which does not materially interfere with, with respect to the Core and Shell, installation of Tenant Improvements, and with respect to Tenant Improvements, the use and occupancy of the Premises by Tenant for the permitted use. In no event, however, shall Substantial Completion be deemed to have occurred prior to (A) with respect to the Core and Shell, the issuance of a certificate of occupancy for the Core and Shell by the municipality, if and to the extent that the municipality issues certificates of occupancy for building cores and shells prior to completion of the interior improvements and the issuance of a certificate of substantial completion by Landlord’s general contractor which is verified by the TI Architect (as defined in the Work Letter), and (B) with respect to the Tenant Improvements, the issuance of a certificate of occupancy for the Tenant Improvements, if and to the extent that the issuance of such certificate of occupancy does not require the installation of Tenant’s furnishings prior to such issuance; provided that any disagreement as to whether Substantial Completion has occurred shall be settled in the manner provided in the Work Letter. If the Substantial Completion of the Core and Shell does not occur within one (1) year after issuance of approved construction documents and a building permit for the Core and Shell, as such period may be extended for events of Force Majeure (the “Outside Core and Shell Delivery Date”), Tenant may elect to terminate this Lease by written notice delivered to Landlord within five (5) days following the Outside Core and Shell Delivery Date, in which event neither party shall have any further rights or obligations hereunder, except that in such event the Original Lease shall be reinstated as of such date of termination as if this Amended and Restated Lease did not exist. If the Substantial Completion of the Tenant Improvements does not occur within sixteen (16) months after issuance of approved Core and Shell Project Construction Documents and a building permit for the Core and Shell, plus one (1) day for each day of delay in the issuance of all necessary building permits for the Tenant Improvements that is more than twelve (12) months after issuance of approved Core and Shell Project Construction Documents and a building permit for the Core and Shell, as such period may be extended for events of Force Majeure (the “Outside Tenant Improvement Delivery Date”), Tenant shall be entitled to one day of free rent, applicable on a pro-rated basis for the New Leased Space only, for each such day of delay commencing on the Outside Tenant Improvement Delivery Date and continuing until Substantial Completion of the Tenant Improvements.

(c) Tenant shall execute and deliver to Landlord a declaration of the Commencement Date upon presentation by Landlord. The term (“Term”) of this Lease shall end fifteen (15) years after the Commencement Date unless sooner terminated or renewed in accordance with this Lease; provided, however, that if the Commencement Date is not the first day of a calendar month, the Term shall extend to the last day of the calendar month which is fifteen (15) years after the Commencement Date occurs.

RENT.

(a) Definitions.

(i) Tenant and Landlord acknowledge and agree that the rentable area of the Existing Building and Existing Leased Space is 78,264 square feet and “Tenant’s Proportionate Share” shall be 100%. The rentable area of the New Leased Space shall be determined by the TI Architect upon Substantial Completion of the Core and Shell, following which the sum of 78,264 square feet and the rentable area of the New Leased Space as so determined shall be the “Rentable Square Footage” of the Leased Space.

(ii) “Real Estate Taxes” shall mean all taxes and assessments levied, assessed or imposed at any time by any governmental authority upon or against the Building and the land upon which the Building is situate, and also any tax or assessment levied, assessed or imposed at any time by any governmental authority in connection with the receipt of income or rents from said Building or land to the extent that the same shall be in lieu of (and/or in lieu of an increase in) all or a portion of any of the aforesaid taxes or assessments upon or against the said Building and/or land. If, however, any assessment included within Real Estate Taxes is payable in installments extending beyond the term of this Lease, Tenant shall only be obligated to pay those installments coming due during the term of this Lease. “Real Estate Taxes” shall not include any penalty or interest as a result of Landlord’s late payment. Landlord further agrees to make payment of Real Estate Taxes in a timely manner so as to take advantage of any applicable discount and to provide to Tenant copies of receipts for paid Real Estate Taxes not later than thirty (30) days after the Real Estate Taxes are due. Failure of Landlord to provide such receipts to Tenant shall permit Tenant to suspend payment of Tenant’s Proportionate Share of Real Estate Taxes until such receipts are furnished to Tenant.

At any time and from time to time during the term of this Lease, Tenant, at its expense, shall have the right to institute proceedings challenging the amount of Real Estate Taxes. Landlord agrees to reasonably cooperate with Tenant in connection therewith. Any refund awarded shall be reimbursed first to each party in proportion to the expenses incurred by such party in prosecuting such appeal, with any balance thereof next being refunded to Tenant in an amount equal to Tenant’s Proportionate Share of (A) the balance of such award remaining after the foregoing cost reimbursements (B) multiplied by a fraction (1) the numerator of which shall be the number of days during the tax year for which the refund is awarded for which Tenant has paid Real Estate Taxes pursuant to this Lease and (2) the denominator of which is 365.

(iii) “Operating Expenses” shall mean that part of any and all expenses reasonably and actually incurred by Landlord in connection with its ownership, maintenance and operation of the Building, the land upon which the Building is situate, excluding Real Estate Taxes and interest or amortization payments on any mortgage, but including, without limitation, electricity (other than as billed directly to Tenant based on usage); insurance maintained on the Building in accordance herewith; all direct and indirect labor costs; a management fee not exceeding four percent (4%) of the aggregate Minimum Annual Rent and Real Estate Taxes and Operating Expenses (“Management Fee”); legal expenses; service contracts and supplies used in

connection with the cleaning, operating, labor and maintenance of the Building; all repairs and decorating required to be performed by Landlord as provided for in this Lease (other than “Landlord’s Work” as defined herein); common area maintenance and snow removal; building supplies, equipment, purchases of goods and services which are expensed, rather than capitalized under generally accepted accounting principles (“GAAP”); all charges for the common areas of the Building for electricity and all charges for the entire Building for water and sewer service, including any taxes on such utilities, removal of trash, rubbish, garbage and refuse; the cost of operating an identification sign or signs for the Building; replacing of paving, curbs, walkways, directional or other signs; drainage; maintenance and monitoring of fire sprinkling systems (if any); the Building’s proportionate share of common expenses owed to the Eagleview Corporate Center Association or its successor or any other similar entity which owns and maintains the common areas of the Center (collectively, “Association”); and such other expenses as Landlord may deem necessary and proper in connection with the operation and maintenance of the Building, excluding any costs which under GAAP are capital expenditures; provided, however, that Operating Expenses shall also include the annual amortization (over the anticipated useful life established in accordance with GAAP) of a capital improvement falling within any of the following categories: (i) a labor saving device or improvement which is intended to reduce or eliminate any other component of Operating Expenses; (ii) an installation or improvement required by reason of any law, ordinance or regulation, which requirement did not exist on the date of this Lease and is generally applicable to similar buildings; (iii) an installation or improvement which directly enhances safety of tenants in the Building or Center generally. Landlord shall have the right to xxxx Tenant directly for any items of Operating Expenses which can be attributed directly to Tenant’s use only.

Notwithstanding any provision to the contrary, Operating Expenses shall not include:

(A) any payments (such as salaries or fees) to the Landlord’s executive personnel or in-house site managers except for the Management Fee;

(B) depreciation or interest, except to the extent permitted above in connection with capital improvements;

(D) taxes on the Landlord’s business (such as income, excess profits, franchise, capital stock, estate, inheritance) except to the extent the same are in lieu of Real Estate Taxes or increases in Real Estate Taxes;

(E) leasing commissions, broker’s fees or legal fees incurred in connection with leases of space in the Building;

(F) legal fees that do not directly benefit Tenant or the Building (provided that legal fees incurred in connection with leases of space in the Building or in enforcing tenant obligations shall not be deemed to benefit the Building);

(G) costs to correct original construction defects or defective repairs or replacements hereinafter provided by or at the direction of Landlord;

(H) costs of repairs covered by valid warranties;

(I) expenses paid directly by a tenant for any reason (such as excessive utility use, direct utility consumption or damage for which such tenant is responsible);

(J) costs for improving any tenant’s space;

(K) any repair or other work necessitated by condemnation, fire or other insured casualty;

(L) any costs, fines and the like due to Landlord’s violation of any law, governmental rule or authority;

(M) refinancing costs;

(N) costs for any conversion of the heating system to gas heat except to the extent such conversion is undertaken in an effort to reduce Operating Expenses and the cost thereof is treated in the same manner as a capital improvement;

(O) costs paid to Landlord or its affiliates other than the Management Fee which exceed those reasonably charged in arms length transactions with third parties in the general area of the Building; and

(P) services, benefits or both provided to some tenants but not to Tenant.

(b) Tenant shall pay Landlord the minimum annual rent (“Minimum Annual Rent”) during the Term in the amounts set forth below, which annual amount shall be paid in equal monthly installments as set forth below on the first day of each calendar month in advance. If the Commencement Date is not the first day of a calendar month, rent from the Commencement Date to the first day of the following month apportioned at the Minimum Annual Rent rate (based on a 365-day year) shall be paid. All rent shall be payable, in advance, and without prior notice or demand, at the address of Landlord set forth in the heading of this Lease or at such other place, or to such other person, as Landlord may from time to time direct in written notice to Tenant. Until the Commencement Date, Minimum Annual Rent shall be as follows:


Lease Period	Rate Per Rentable Square Foot of Existing Leased Space		Minimum Annual Rent		Monthly Installment
Effective Date-10/31/12	$	16.75	$	1,310,922.00	$	109,243.50
11/1/12-10/31/13	$	17.30	$	1,353,967.20	$	112,830.60
11/1/13-10/31/14	$	17.85	$	1,397,012.40	$	116,417.70
11/1/14-10/31/15	$	18.30	$	1,432,231.20	$	119,352.60
11/1/15-4/30/16	$	18.75	$	1,467,450.00	$	122,287.50

At such time as the Commencement Date occurs, in lieu of the Minimum Annual Rent as set forth in the above table, Minimum Annual Rent shall be an amount (the “Initial Year Minimum Annual Rent”) equal to $13.95 multiplied the Rentable Square Footage of the Leased Space (estimated to be 149,264), payable in monthly installments each in the amount of 1/12 of the Minimum Annual Rent.

Such Initial Year Minimum Annual Rent shall remain in effect for the first year following the Commencement Date (which first year shall extend to the end of the twelfth full calendar month following the Commencement Date, if the Commencement Date is other than the first day of the month), and thereafter Minimum Annual Rent shall increase by the percentage increase in the Consumer Price Index-Philadelphia SMSA-All Urban Consumers (1982-1984 = 100) (“CPI-U”) most recently published by the Bureau of Labor Statistics of the United States Department of Labor prior to each annual anniversary of the Commencement Date (“Adjustment Index”) over the CPI-U published most recently prior to the Commencement Date (“Base Index”). Such percentage will be multiplied by the Initial Year Minimum Annual Rent and added to the Initial Year Minimum Annual Rent to calculate the Minimum Annual Rent for each year after the first year of the Term.

(c) In addition, Tenant shall pay to Landlord as Additional Rent in equal monthly installments one twelfth (1/12) of Tenant’s Proportionate Share of annual Real Estate Taxes and Operating Expenses, at the time of payment of each monthly installment of Minimum Annual Rent, based upon the most recent costs of Operating Expenses and Real Estate Taxes available. For the period from the date hereof until the issuance of a statement pursuant to subparagraph 3(d) below, such monthly installment shall be equal to $38,479.80, from the Effective Date until the Commencement Date and thereafter $73,388.13, provided that on the Commencement Date, Landlord may issue a new estimate of Tenant’s Proportionate Share of annual Real Estate Taxes and Operating Expenses taking into account Landlord’s good faith estimate of the same for the entire Leased Space, and Tenant shall thereafter pay one-twelfth (1/12) thereof in equal monthly installments as Tenant’s Proportionate Share of annual Real Estate Taxes and Operating Expenses until issuance of a reconciliation statement pursuant to subsection (d) below.

(d) Within ninety (90) days of the expiration of each calendar year Landlord shall furnish Tenant with a written statement of the actual Operating Expenses and Real Estate Taxes incurred for such year itemizing the expenses claimed by Landlord in reasonable detail. Within ten (10) days of the rendition of such statement, Tenant shall pay any amounts in excess of those collected pursuant to the payments on account of Real Estate Taxes and Operating Expenses pursuant to paragraph 3(c) hereof, and any overpayments shall be credited against the next installment(s) of rent due under this Lease or, at Tenant’s option, refunded to Tenant. In the event the first and/or last years of the Term of this Lease shall not be full calendar years, then Tenant’s obligation for Operating Expenses and Real Estate Taxes attributable to such years shall be pro rated. In addition, Landlord may issue an interim statement pursuant to this paragraph for the portion of the calendar year ending on the Commencement Date, and a second statement for the remainder of such calendar year. Tenant may, at its own cost and expense, after full payment of all sums due and owing, audit Landlord’s books and records not more than once each year within sixty (60) days after Landlord’s delivery of its annual statement of Operating Expenses, which books and records shall be maintained in accordance with GAAP. Notwithstanding the foregoing, if any said review of Landlord’s books and records reveals that any item(s) were incorrectly included in Operating Expenses, Tenant shall have the right to inspect Landlord’s books and records with respect to such items for each prior lease year and an adjustment, if any, shall be made in accordance herewith. If Tenant’s audit determines that Landlord’s total charges for Operating Expenses or Real Estate Taxes for a given lease year exceed by more than 5% the total amount properly chargeable to Tenant under this Lease for such year, Landlord, in addition to reimbursing Tenant such excess amount, shall pay Tenant an amount equal to the cost of the audit.

(e) Upon the Commencement Date, Tenant shall pay to Landlord a sum equal to the unamortized principal balance of a hypothetical fully amortizing loan made by Landlord to Tenant on September 1, 2008 in the original principal amount of $2,347,920.00, such amount being the fit out cost funded by the Landlord for the Existing Leased Space, with an interest rate at 7.25% per annum, over a term of 90 months, and hypothetical equal payments of combined principal and interest in the amount of $33,897.13 each having been made on October 1, 2008 and on the first day of each month thereafter during the Term of the Original Lease, and during the Term of this Lease including the last such monthly payment prior to the Commencement Date of this Lease. Attached hereto as Exhibit C is an amortization table showing the principal, interest and outstanding balance each month for such hypothetical loan, reflecting that payments were paid in advance.

ADDITIONAL RENT.

Tenant shall pay to Landlord as “Additional Rent” (in addition to sums payable pursuant to paragraphs 3 (c) and 3(d)) the following:

(a) Expenses Incurred by Landlord as a Result of Tenant’s Default. All sums which may become due by reason of Tenant’s failure to comply with any of the terms, conditions and covenants of this Lease to be kept and observed by Tenant, and any and all damages, costs and expenses (including without limitation thereto reasonable attorney’s fees) which Landlord

may suffer or incur by reason of any default of Tenant and any damage to the Building or the real estate of which the Building is a part caused by any negligence or willful misconduct of Tenant or violation of Tenant’s covenants in Section 5(a) below (subject, however, to the provisions of Section 17(e) below), together with interest to the date of payment (whether before or after entry of judgment and issuance of execution thereon) at a rate equal to five percent (5%) above the prime interest rate (or similar rate if the prime interest rate is no longer published) as published in The Wall Street Journal, in effect on the date during the period said payment is due (“Default Rate”), which shall continue to accrue interest at the Default Rate after entry of judgment and issuance of execution thereon until paid in full.

(b) Use and Occupancy Taxes. All use and occupancy taxes imposed by any governmental body allocable to the Leased Space.

(c) Utilities. Tenant shall pay all charges for gas and electric, as billed directly by the providers of the same to Tenant.

(d) Work Letter. Tenant shall pay all amounts when and as required in the Work Letter.

For purposes of this Lease, the term “Rent” or “rent” shall be deemed to refer to Minimum Annual Rent and Additional Rent.

(i) damage the Leased Space or any other part of the Building;

(ii) bring into or permit to be kept in the Leased Space any dangerous, explosive or obnoxious substances except as may be used in Tenant’s Business which use Tenant shall undertake in compliance with all applicable laws regulating same;

(iii) conduct itself or permit its agents, servants, employees or invitees to conduct themselves in a manner that in Landlord’s judgment reasonably exercised is improper or unsafe except that the operation of, or activities related to, Tenant’s Business in a manner consistent with the use of the Leased Space permitted by this Lease shall not be deemed to violate this provision, provided same are undertaken in compliance with all applicable laws;

(iv) manufacture any commodity or prepare or dispense any food or beverages in the Leased Space, except for consumption in the Leased Space by Tenant, its employees or invitees;

(v) remove, attempt to remove or manifest any intention to remove Tenant’s goods or property from the Leased Space other than in the ordinary course of business;

(vi) do or suffer to be done, any act, matter or thing objectionable to Landlord’s fire insurance companies or Board of Underwriters whereby the fire insurance or any other insurance now in force or hereafter to be placed by Landlord on the Leased Space or the Building or Center shall become void or suspended or whereby the manner in which Tenant conducts Tenant’s Business causes the Leased Space, Building or Center to be rated as a more hazardous risk than at the Commencement Date. Tenant agrees to pay to Landlord as Additional Rent, any and all increases in premiums for insurance carried by Landlord on the Leased Space, or on the Building, caused in any way by the occupancy of Tenant.

(iv) Tenant’s Indemnity.

(A) Tenant shall indemnify, defend, and hold harmless Landlord, the manager of the Center, and their respective officers, directors, beneficiaries, shareholders, partners, agents and employees, from all fines, suits, procedures, claims, and actions of every kind, and all costs associated therewith (including reasonable attorneys’ and consultants’ fees) arising out of or in any way connected with any deposit, spill, discharge, or other release of Hazardous Substances that occurs during the Term of this Lease at or from the Leased Space and which arises at any time from use of Hazardous Substances by Tenant Responsible Parties, or from failure by Tenant Responsible Parties to provide all information, make all submissions, and take all steps required by all Authorities under the Laws with respect thereto.

(B) Tenant’s obligations and liabilities under this Subparagraph (iv) shall survive the expiration of this Lease.

(a) Landlord shall, without cost to Tenant except as provided in the Work Letter, and except to the extent of any incremental increase in Landlord’s cost of completing the Core and Shell caused by governmental requirements imposed solely by reason of any governmental grants, economic development loans or the like obtained by Tenant which mandate the manner of construction, prevailing wage requirements or the like, complete the “Core and Shell” as defined in the Work Letter attached hereto. Following receipt by Landlord of notice from Tenant of Tenant’s receipt of such grants, economic development loans or the like which Tenant intends to utilize, Landlord shall promptly notify Tenant of Landlord’s estimate of any incremental increase in Landlord’s cost, as described above, so that Tenant may elect, in its sole discretion, not to take advantage of such grants or loans. If the Core and Shell Plans as defined in the Work Letter, or a description thereof which is reasonable to identify same, have not been attached hereto upon execution hereof, the Core and Shell Plans when completed in accordance with the Work Letter shall be initialed for identification by Landlord and Tenant and become part of this Lease when so initialed. Any incremental increase in Landlord’s cost of completing the Core and Shell caused by governmental requirements imposed by reason of any governmental grants, economic development loans or the like which mandate the manner of construction, prevailing wage requirements or the like shall be paid by Tenant to Landlord as such increased costs are incurred, within thirty (30) days of billing by Landlord to Tenant.

(b) Following Substantial Completion of the Core and Shell, Landlord shall construct the Tenant Improvements upon the terms and conditions provided in the Work Letter.

(d) Notwithstanding any provision of this Lease or the Work Letter to the contrary, under no circumstances shall Landlord’s construction obligations relate to the furnishing and installing a generator and information technology equipment, which is intended to be funded by grants being sought by Tenant from the Commonwealth of Pennsylvania.

TENANT’S ALTERATIONS.

(a) Except as hereafter provided, Tenant shall make no alterations, additions or improvements (“Tenant Alterations”) to the Leased Space without the consent of Landlord, which consent shall not be unreasonably withheld, delayed or conditioned. Tenant Alterations

contemplated by Tenant, the location, plans and specifications for which shall be subject to Landlord’s consent, not to be unreasonably withheld, delayed or conditioned, may include a generator and diesel fuel tank related thereto on the Land and connections to the Building and the equipment and systems therein and additional HVAC equipment. At the time of Landlord’s consent, Landlord shall designate whether Tenant shall be required to remove the proposed Tenant Alteration upon termination of this Lease, and the absence of such designation in Landlord’s written consent shall be deemed Landlord’s agreement that Tenant shall not be obligated to remove Tenant Alterations upon the termination of this Lease. Landlord also may impose such reasonable conditions as part of its consent as Landlord deems appropriate, taking into consideration the nature of the proposed Tenant Alteration, including, without limitation, requiring Tenant to furnish Landlord with security for the payment of all costs to be incurred in connection with such work, insurance, and copies of the plans, specification and permits necessary for such work. Nothing herein, however, shall be construed to obligate Tenant to construct any Tenant Alteration for which Landlord has given its consent.

(b) Landlord’s consent shall not be required for Tenant Alterations which (i) do not adversely impact the structural integrity of the Building or the systems serving the Building or their operation, (ii) are not visible from the Building exterior and (iii) the cost of which is $10,000 or less with respect to any Tenant Alteration project (or $20,000 or less in the aggregate with respect to Tenant Alteration projects undertaken over any twelve (12) consecutive month period). Tenant Alterations described in this subsection (b) for which Landlord’s consent is not required hereinafter are called “Permitted Tenant Alterations.” Notwithstanding the foregoing, painting or carpeting of the interior of the Leased Space and like cosmetic improvements shall not be deemed Tenant Alterations regardless of the cost thereof. Tenant shall not be obligated to remove Permitted Tenant Alterations upon the termination of this Lease unless an Event of Default has occurred which is then continuing and Landlord so requires such removal.

(c) All Tenant Alterations shall be done at Tenant’s expense by contractors approved by Landlord, which consent shall not be unreasonably withheld, delayed or conditioned and shall be deemed given unless Landlord notifies Tenant of its objections within ten (10) business days after delivery of Tenant’s request for consent. The parties agree that it shall not be unreasonable for Landlord to require any connections to the Building of any Tenant Alterations, which may impact the Building’s HVAC, plumbing, mechanical or electrical systems, to be made by a contractor designated by Landlord, provided, however, that Landlord agrees that Tenant shall be permitted to use Penncat Corporation in connection with the installation of any generator in the Premises, and all other contractors shall charge market rates. With respect to Tenant Alterations other than the Permitted Tenant Alterations, no work shall be performed until the plans therefore have been approved by Landlord, which approval shall not be unreasonably withheld, delayed or conditioned and shall be deemed approved unless Landlord notifies Tenant of objections to the proposed plans within ten (10) business days after delivery to Landlord of a complete set of the plans therefor. In connection with the review of plans submitted by Tenant, Landlord shall be reimbursed by Tenant for Landlord’s cost in reviewing such plans at the rate of $100 per hour; subject to reasonable increase to reflect the then current hourly charge imposed for such review by Landlord for its tenants in the Center generally, and prior to undertaking any

such review, Landlord shall provide a statement of the maximum review hours to be dedicated to such review. With respect to Permitted Tenant Alterations, Tenant shall provide Landlord with a copy of Tenant’s application for a building permit therefor, if applicable (together with all attachments thereto), and no review fee shall be charged to Tenant by Landlord in connection therewith nor shall Landlord’s approval of such application be required. Tenant shall provide copies of as-built plans and specifications for all Tenant Alterations to Landlord within a reasonable time of completion of the Tenant Alteration. All Tenant Alterations shall be done in a first class, workmanlike manner and shall comply with all insurance requirements then made available to Tenant and all applicable laws, ordinances, rules and regulations of governmental authorities having jurisdiction thereover, and, where applicable, with all reasonable requirements of Landlord imposed as a condition of such consent.

(d) If, as a condition of Landlord’s consent, removal of a Tenant Alteration is required at termination of this Lease, Tenant shall promptly remove such Tenant Alterations and repair any damage occasioned by such removal. In default thereof, Landlord may effect said removal and repairs at Tenants expense. With respect to any Tenant Alterations which Tenant is not obligated to remove hereunder (including without limitation Permitted Tenant Alterations), such Tenant Alterations, if not removed by Tenant upon the termination of this Lease, shall be deemed abandoned by Tenant, and deemed a part of Landlord’s property, notwithstanding any provision of Section 16 to the contrary.

MECHANIC’S LIENS.

If Tenant performs or orders (other than through Landlord or Landlord’s contractors) any construction or other work on or about the Leased Space for which a lien could be filed against the Leased Space or the Building, Tenant shall obtain from the contractor who performs such work a release of any liens which could be filed under the Mechanics’ Lien Law of the Commonwealth of Pennsylvania for such work which has been completed and paid for by Tenant, at the time of payment, and obtain similar releases from all subcontractors, sub-subcontractors and material suppliers. Notwithstanding the foregoing, if any mechanics’ or other lien shall be filed against the Leased Space or the Building purporting to be for labor or material furnished or to be furnished at the request of the Tenant other than through Landlord or Landlord’s contractors, then Tenant shall at its expense cause such lien to be discharged of record by payment, bond or otherwise, within fifteen (15) days after Tenant receives notice of the filing thereof. If Tenant shall fail to cause such lien to be discharged by payment, bond or otherwise within such period, Landlord may cause such lien to be discharged by payment, bond or otherwise, without investigation as to the validity thereof or as to any offsets or defenses thereto, and Tenant shall, upon demand, reimburse Landlord for all amounts paid and costs incurred, including attorneys’ fees, in having such lien discharged of record. If, however, Tenant notifies Landlord during such fifteen (15) day period that it disputes the validity of such lien and provides security reasonably acceptable to Landlord in an amount which is sufficient to discharge such lien in full, Landlord shall refrain from satisfying such lien for a period not to exceed one hundred twenty (120) days.

10.

CONDITION OF LEASED SPACE.

Tenant acknowledges and agrees that, except as expressly set forth in this Lease, there have been no representations or warranties made by or on behalf of Landlord with respect to the Leased Space or the Building or with respect to the suitability of either for the conduct of Tenant’s Business.

11.

BUILDING SERVICES.

Landlord shall operate and maintain the Building and the Center in a manner comparable to other office buildings in Exton, PA. Landlord shall provide all heat, light, electricity, air conditioning and restroom facilities, and janitorial services (as shown on Exhibit D attached hereto), and as otherwise required by Tenant. It is understood that this Lease is intended to be net of taxes, repairs, insurance and operating expenses. Tenant shall have access to the Leased Space on a 24 hour per day, 7 day per week basis and Landlord shall provide heat, light, electricity, air conditioning and restroom facilities during those hours, provided, however, Landlord shall not be obligated to provide maintenance services, including without limitation, repairs, and snow removal other than a reasonable time prior to and during normal business hours (8 AM to 6 PM, Monday through Friday), sufficient to allow Tenant’s ordinary use of the Leased Space, during normal business hours. Where such services are required because of an emergency other than during normal business hours, Landlord shall use reasonable efforts to provide them other than during normal business hours as the emergency may require. Landlord shall provide normal janitorial services after normal business hours.

Unless otherwise agreed with Tenant in writing, Landlord agrees that all maintenance to the common areas external to the Building which the Association offers to perform or is obligated to perform for the benefit of lots in the Center shall be performed by the Association. Landlord shall use diligent efforts to enforce any such obligation of the Association. Except during such period of time as Landlord or its affiliates control the Association, Landlord shall not be liable in damages or otherwise for temporary delay or failure in furnishing any services or facilities to be provided by Landlord or the Association under this Lease or any other agreement between Tenant and Landlord (or its agents) or implied by law.

Landlord shall maintain, repair and replace, when needed the foundation, roof and exterior walls, exterior of and the frames surrounding all windows, doors and plate glass, and maintain and make when required repairs to the Building and areas of the Center. In lieu of repairing items whose useful life has been exhausted or which have been damaged beyond repair, which damage was not caused by abuse by Tenant, its agent and invitees, in Landlord’s judgment exercised in good faith, Landlord shall replace such items. Tenant shall give Landlord written notice of the need for the above repairs. Landlord shall cause such repair or replacement to be performed in a good and workmanlike manner and within a reasonable time after receipt of written notice from Tenant stating the need therefor. Subject to the provisions of Section 17(e), the cost of any repairs or replacements, even if otherwise not to be part of Operating Expenses, caused by the negligence, misuse or misconduct of Tenant or its agents or invitees, shall be paid by Tenant.

12.

ASSIGNMENT AND SUBLETTING.

(a) Tenant shall not, without the prior written consent of Landlord, assign or mortgage this Lease or any interest therein or sublet the Leased Space or any part thereof. For the purposes of this paragraph, the sale or assignment of a controlling interest in the Tenant corporation or a majority interest in the Tenant partnership as the case may be, shall be deemed an assignment, but the assignment to a parent, wholly-owned subsidiary of the Tenant or successor corporation shall be permitted, provided that such assignee assumes the obligations of Tenant and that such assignment shall not relieve Tenant of its obligations hereunder. For purposes herein, (A) a successor corporation is one into which Tenant is merged or consolidated, or which acquired those of Tenant’s assets or business located in the Leased Space as of the date of the assignment, and (B) a controlling interest shall mean the ownership of fifty percent or more of the beneficial interest in the person or entity in question, unless the corporation is publicly traded in which case such transfers of stock (whether or not a controlling interest) shall not be deemed to be an assignment. As to any other assignment or subleasing, Landlord agrees that it shall not unreasonably withhold its consent, provided the business of Tenant’s assignee or subtenant is no more hazardous than that of Tenant, it being understood that Landlord shall not be obligated to consent at the time there is other comparable space available for lease at the Center which is owned by Landlord or an affiliate of Landlord, and that it shall not be unreasonable for Landlord to require, as a condition of such consent:

(b) That 50% of any money or other economic consideration received by Tenant as a result of such subletting or assignment and which is not properly allocable to any lease of Tenant’s personal property in the Leased Space or sale of Tenant’s assets from the business operated at the Leased Space or sale of Tenant’s stock or other arms-length transaction, which exceeds, in the aggregate, the total sums which Tenant is obligated to pay Landlord under this Lease (pro rated to reflect obligations allocable to that portion of the Leased Space subject to the sublease or assignment) shall be payable to Landlord as Additional Rent under this Lease without affecting or reducing any other obligation of Tenant hereunder; and

(c) Unless otherwise agreed in Landlord’s consent, no subletting or assignment shall release Tenant of Tenant’s obligation or alter the primary liability of Tenant to pay the rental and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rental by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to one assignment or subletting shall not be deemed consent to any subsequent assignment or subletting. In the event of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such assignee or successor. Landlord may consent to subsequent assignment or subletting of this Lease or amendments or modifications to this Lease with assignees of Tenant, without notifying Tenant, or any successor of Tenant, and without obtaining its or their consent thereto and such action shall not relieve Tenant of liability under this Lease.

13.

ACCESS TO LEASED SPACE.

Landlord, its employees and agents, shall have the right to enter the Leased Space at all reasonable times for the purpose of examining or inspecting the same, showing the same to prospective purchasers or tenants of the Building, or mortgagees, and making such alterations, repairs, improvements or additions to the Leased Space or to the Building as Landlord may deem necessary or desirable provided such alterations, repairs, improvements or additions do not adversely affect Tenant’s Business or use of the Leased Space or, except with Tenant’s consent, alter the Tenant Improvements performed in accordance with the Work Letter or approved Tenant’s Alterations. Except in case of emergency in Landlord’s reasonable judgment, any such entry shall be after reasonable notice to Tenant and in compliance with Tenant’s practices from time to time established with respect to areas where confidential information is located. If a representative of Tenant shall not be present to open and permit entry into the Leased Space at any time when such entry by Landlord is necessary in an emergency, Landlord may enter by means of a master key (or forcibly) without liability to Tenant and without such entry constituting an eviction of Tenant or termination of this Lease. All keys must be returned to Landlord at the expiration or termination of the Lease.

14.

REPAIRS.

(a) Landlord shall repair, maintain and as necessary, replace, the roof, load bearing walls (other than paint and wall coverings), floors (other than carpeting, tile and similar floor coverings), foundations and other structural elements of the Building, and all plumbing and electrical fixtures and equipment and HVAC system components serving the Building; provided, however, that Landlord shall not be obligated for any of such repairs until the expiration of a reasonable period of time after written notice that such repair is needed. The cost of same shall be included in the Operating Expenses to the extent provided in Section 3(a)(iii) unless the necessity for any of the foregoing arises (a) from the gross negligence or willful and wanton misconduct of Landlord or its employees or, subject to clause (I) of the second paragraph of Section 3(a)(iii) hereof, by any other tenant of the Center or such tenant’s agents, employees, licensees, or invitees, in which case such cost shall not be included as part of the Operating Expenses but shall be paid by Landlord (without prejudice to Landlord’s right to recover same from the responsible party), or (b) negligence or willful and wanton misconduct of Tenant, its agents, employees, licensees or invitees, in which case such cost shall be paid by Tenant. Any such maintenance, replacements or repairs and any labor performed or materials furnished by or upon the direction of Landlord shall be performed in a good and workmanlike manner, using only materials of at least the same quality and integrity as that being repaired or replaced, and performed and furnished in compliance with all applicable laws, regulations, ordinances and requirements of all duly constituted authorities or governmental bodies having jurisdiction over the Building, and the requirements of any board of underwriters having jurisdiction thereof.

(b) Except as the Landlord is obligated for repairs as provided above or in Section 11, Tenant shall make, at its sole cost and expense, all repairs necessary to maintain the Leased Space and the fixtures therein in neat and orderly condition. If the Tenant refuses or neglects to make such repairs or fails to diligently prosecute the same to completion after written notice from Landlord of the need therefore and a reasonable time for cure, Landlord may make

such repairs at the expense of Tenant and such expense shall be collectible as Additional Rent. Any such repairs and any labor performed or materials furnished in, on or about the Leased Space shall be performed and furnished by Tenant in compliance with all applicable laws, regulations, ordinances and requirements of duly constituted authorities or central bodies having jurisdiction over the Building, the requirements of any board of underwriters having jurisdiction thereof, as well as any reasonable regulations imposed by Landlord pertaining thereto. Without limitation of the foregoing, Landlord shall have the right to approve any and all contractors and suppliers to furnish materials and labor for such repairs, which consent shall not be unreasonably withheld, delayed or conditioned.

(c) If required solely as a result of Tenant’s particular activities at the Leased Space (as opposed to general occupancy thereof by any tenant), Tenant also shall comply with, and make any repairs and installations required by any applicable law.

(d) Provided that Landlord shall exercise reasonable efforts to effectuate its repairs in a manner which will keep at a minimum Landlord’s interference with Tenant’s use and occupancy of the Leased Space, Landlord shall not be liable by reason of any injury to or interference with Tenant’s Business arising from the making of any repairs, alterations, additions or improvements in or to the Leased Space, or the Building or Center or to any appurtenances or equipment therein.

15.

TERMINATION AND EXTENSION.

(a) It is hereby mutually agreed that this Lease shall terminate at the end of the term if a renewal right has not been exercised, or if exercised, upon the end of any renewal term, without notice by either party.

(b) If Tenant shall hold over after the expiration of the Term hereof, and Landlord shall not give consent to such hold over by Tenant, such tenancy may be terminated as permitted by applicable state law, and until Tenant has vacated the Leased Space, it agrees to pay to Landlord rent at a monthly rental double the rate payable by Tenant at the expiration of the Term of this Lease.

16.

SURRENDER OF LEASED SPACE.

At the end of the Term of this Lease, Tenant shall surrender the Leased Space to Landlord, in broom clean condition and in good order and repair except for ordinary wear and tear and damage for which Tenant is not obligated to make repairs under this Lease. Subject to Sections 8 and 9 hereof and if an Event of Default has not occurred which is then continuing, Tenant shall have the right at the end of the Term hereof to remove any Tenant Alterations and any equipment, furniture, trade fixtures or other personal property placed in the Leased Space by Tenant, provided that Tenant promptly repairs any damage to the Leased Space caused by such removal. Tenant shall repair all damage to the Leased Space caused by such removal and restore the Leased Space to the condition in which they were prior to the installation of the items so removed, reasonable wear and tear and damage by casualty not caused by Tenant excepted. Tenant shall surrender the Leased Space to Landlord at the end of the term hereof, without notice of any kind, and Tenant waives all right to any such notice as may be provided under any laws now or hereafter in effect in Pennsylvania. If Tenant shall fail to remove any Tenant Alterations which it was required to remove pursuant to Section 8 of this Lease or any of its equipment, furniture, trade fixtures or other personal property, Landlord may remove and store the same at the expense of Tenant or sell the same on behalf of Tenant at public or private sale in such manner as is commercially reasonable, with any proceeds thereof to be first applied to the costs and expenses, including attorney’s fees, of the storage and sale and the payment of any amounts owed hereunder by Tenant.

17.

INDEMNIFICATION AND INSURANCE.

(a) Tenant covenants and agrees that it shall, without notice or demand and at its own cost and expense, indemnify and save harmless Landlord against and from, and Landlord shall not be liable to Tenant for, any and all claims by or on behalf of any person arising in any manner whatsoever from, out of, or in connection with any accident, death, injury, or damage, loss or theft of property in or about the Leased Space (whether involving property belonging to Tenant or any other person) resulting from the negligence or willful misconduct of Tenant, its agents, employees, licensees or invitees, and from and against all costs, reasonable attorney fees, expenses and liabilities incurred in or as a result of any such claim or action or proceeding brought against Landlord by reason of any such claim. Tenant, upon notice from Landlord, covenants to resist or defend such action or proceeding by legal counsel reasonably satisfactory to Landlord. The indemnification obligations under this paragraph shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Tenant, or any other person, under Workers or Xxxxxxx’x Compensation statutes, disability benefits statutes or other employee benefit laws.

(b) Tenant shall keep in force commercial general liability insurance with respect to the Leased Space, including contractual insurance with respect to the covenants and agreements above, with companies and in form reasonably acceptable to Landlord to afford protection of not less than Two Million ($2,000,000.00) Dollars with respect to personal injury or death and property damage, and naming Landlord as an additional insured and providing not less than thirty (30) days’ notice of cancellation. Copies of such policies or a certificate of insurance evidencing same shall be delivered to Landlord.

(c) Landlord covenants and agrees that it shall, without notice or demand and at its own cost and expense, indemnify and save harmless Tenant against and from, and Tenant shall not be liable to Landlord for, any and all claims by or on behalf of any person arising in any manner whatsoever from, out of, or in connection with any accident, death, injury, or damage, loss or theft of property in or about the Leased Space (whether involving property belonging to Landlord or any other person) resulting from the gross negligence or wanton and willful misconduct of Landlord, its agents or employees, and from and against all costs, reasonable attorney fees, expenses and liabilities incurred in or as a result of any such claim or action or proceeding brought against Tenant by reason of any such claim. Landlord, upon notice from Tenant covenants to resist or defend such action or proceeding by legal counsel reasonably satisfactory to Tenant. The indemnification obligations under this paragraph shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Landlord, or any other person, under Workers or Xxxxxxx’x Compensation statutes, disability benefits statutes or other employee benefit laws.

(d) Landlord shall keep in force commercial general liability insurance with respect to the Building, including contractual insurance with respect to the covenants and agreements above, with companies and in form reasonably acceptable to Tenant to afford protection of not less than Two Million ($2,000,000.00) Dollars with respect to personal injury or death and property damage, and naming Tenant as an additional insured and providing not less than thirty (30) days’ notice of cancellation. Copies of such policies or a certificate of insurance evidencing same shall be delivered to Tenant.

(e) All property insurance policies also shall contain a clause or endorsement denying the insurer any rights of subrogation against Landlord, in the case of Tenant’s insurer, and Tenant, in the case of Landlord’s insurer. As to any loss or damage covered by insurance containing a waiver of subrogation clause or similar endorsement, or to the property of a party arising from a peril normally covered by the ISO Causes of Loss-Special Form (CP 10 30) insurance policy, or its equivalent, with coverage extended for the perils of flood and earthquake, each party hereby releases the other, from any and all liability for such loss or damage to such party’s property, even if such loss or damage shall be brought about by the fault or negligence of such other party, or the agents, employees, invitees or licensees of such other party.

18.

FIRE OR OTHER CASUALTY.

(a) At all times during the Term of this Lease, Landlord shall maintain in full force and effect a property insurance policy on the Building against loss from perils covered by the ISO Causes of Loss-Special Form (CP 10 30), or its equivalent, with coverage extended for the perils of flood and earthquake, in an amount equal to full insurable replacement cost. Such insurance shall contain an agreed valuation provision in lieu of any co-insurance clause, an ordinance and law endorsement, debris removal coverage, and a waiver of subrogation endorsement in favor of Landlord. Such policy may include a commercially reasonable

deductible. The premium for such insurance shall be included as an Operating Expense. Such coverage shall be issued by any reputable insurance company licensed in Pennsylvania, with at least a Best’s rating of “A” or better. Landlord agrees to deliver a certificate evidencing such insurance coverage upon Tenant’s request from time to time.

(b) If the Leased Space or the Building is partially damaged by fire or other casualty such that Tenant is able to conduct its business therein at a reduced but economically feasible level on a temporary basis, and insurance proceeds are available to Landlord, the damages shall be repaired by and at the expense of Landlord and the rent, until such repairs shall be made, shall be apportioned from the date of such fire or other casualty according to the part of the Leased Space which is usable by Tenant. Landlord agrees to repair such damage within a reasonable period of time after receipt from Tenant of written notice of such damage, except that Tenant agrees to repair and replace its own furniture, furnishings and equipment which were not provided as part of the Tenant Improvements. If Landlord is unable to complete reconstruction of the damaged premises within two hundred ten (210) days from the date of the casualty, Tenant shall have the right to terminate this Lease.

(c) If the Leased Space or Building is totally damaged or is rendered wholly untenantable by fire or other casualty, each party shall have the right to terminate the Lease by written notice to the other on or before thirty (30) days after such casualty occurred. If, however, Landlord consents in writing within thirty (30) days following such casualty to reconstruct the damaged premises to the condition which existed prior to such casualty and a reputable contractor acceptable to Landlord and Tenant determines that such reconstruction can be substantially completed within two hundred ten (210) days from the date of such casualty, neither party shall have the right to terminate this Lease and Landlord shall undertake reconstruction of the damaged premises. If, however, Landlord is unable to complete reconstruction of the damaged premises within two hundred ten (210) days from the date of the casualty, Tenant shall have the right to terminate this Lease.

(d) Whenever Landlord shall be obligated hereunder to reconstruct damaged premises, Landlord agrees to undertake such reconstruction with reasonable diligence and, if Tenant shall remain in possession of any portion of the Leased Space, in such manner to as to minimize interference or disruption of Tenant’s use of the Leased Space. Reconstruction shall be performed in a good and workmanlike manner, in accordance with standard construction practices and safety procedures, using only materials of at least equal quality and integrity as the materials damaged by the casualty, undertaken in such manner so as to restore the damaged premises to substantially the condition which existed prior to such casualty, and performed and furnished in compliance with all applicable laws, regulations, ordinances and requirements of all duly constituted authorities or governmental bodies having jurisdiction over the Building, and the requirements of any board of underwriters having jurisdiction thereof. For purposes of implementing the foregoing, the parties agree to substantially adhere to the practices established by the Work Letter attached hereto.

(e) Upon the termination of this Lease under the conditions hereinbefore provided, Tenant’s liability for rent shall cease as of the day of the casualty. Tenant shall

promptly vacate and surrender the Leased Space to Landlord in its “as is” condition, whereupon neither party shall have any further rights or obligations hereunder except that Landlord shall reimburse to Tenant (i) any portion of the Security Deposit not otherwise applied by Landlord in accordance with this Lease, and (ii) prepaid Rent paid by Tenant. Such reimbursement shall be made in full to Tenant not later than thirty (30) days following termination of this Lease, and if not so paid, such unpaid amounts shall accrue interest at the Default Rate specified in this Lease from the date of termination until paid in full. The limitations set forth in Section 28 hereof shall not apply to Landlord’s liability for payment of the foregoing amounts.

19.

CONDEMNATION.

If the Leased Space or the Building or any material part of either shall be condemned or otherwise subject to an eminent domain proceeding, then and in that event, upon the transfer of title to the authority exercising such power, this Lease shall terminate, and all rent paid in advance shall be apportioned as of the date of such termination. Notwithstanding the foregoing, if only a part of the Leased Space shall be so taken and the part not so taken shall be sufficient in Tenant’s reasonable judgment for the economic and feasible operation of Tenant’s business, Tenant, at its election, may retain the part not so taken and there shall be a proportional reduction in the rent. All compensation awarded or paid upon such a total or partial taking of the Leased Space shall belong to and be the property of the Landlord, provided that if this Lease is not terminated as provided herein Rent shall xxxxx during such restoration period, pro-rated for the portion of the Leased Space not useable. The foregoing shall not, however, be construed to preclude the Tenant from prosecuting any claim directly against the condemning authority in such condemnation proceedings for loss of business, or depreciation to, damage to, or cost of removal of, or for the value of stock, trade fixtures, furniture, and other personal property belonging to the Tenant, provided, however, that no such award or claim shall diminish or otherwise adversely affect the Landlord’s award (subject to Tenant’s interest therein as aforesaid).

20.

ESTOPPEL CERTIFICATES.

At any time, and from time to time, upon the written request of Landlord or any “Mortgagee” (as defined in Section 29 hereof), Tenant, within ten (10) business days of the date of such written request, agrees to execute and deliver to Landlord and/or such Mortgagee, a written statement: (a) ratifying this Lease; (b) confirming the commencement and expiration dates of the Term of this Lease; (c) certifying that Tenant is in occupancy of the Leased Space, and that the Lease is in full force and effect and has not been modified, assigned, supplemented or amended except by such writings as shall be stated; (d) certifying that all conditions and agreements under this Lease to be satisfied or performed by Landlord have been satisfied and performed except as shall be stated; (e) certifying that Landlord is not in default under the Lease and there are no defenses or offsets against the enforcement of this Lease by Landlord, or stating the defaults and/or defenses claimed by Tenant; (f) reciting the amount of advance rent, if any, paid by Tenant and the date to which such rent has been paid; (g) reciting the amount of security deposited with Landlord, if any; and (h) any other information which Landlord or the Mortgagee reasonably may require. The failure of Tenant to execute, acknowledge and deliver to Landlord and/or any Mortgagee a statement in accordance with the provisions herein within the period set

forth herein shall constitute an acknowledgment by Tenant which may be relied upon by any person holding or intending to acquire any interest whatsoever in the Leased Space or the Building that this Lease has not been assigned, amended, changed or modified, is in full force and effect and that the Minimum Annual Rent, and Additional Rent have been duly and fully paid not beyond the respective due dates immediately preceding the date of the request for such statement and shall constitute as to any persons entitled to rely on such statements (other than Landlord) a waiver of any defaults by Landlord or defenses or offsets against the enforcement of this Lease by Landlord which may exist prior to the date of the written request.

21.

DEFAULT.

The occurrence of any of the following shall constitute an “Event of Default” of this Lease by Tenant:

(a) A failure by Tenant to pay, when due, any installment of rent hereunder or any such other sum herein required to be paid by Tenant where such failure continues for ten (10) days after written notice thereof from Landlord; provided however said written notice shall not be required to be given by Landlord more than twice in any twelve (12) month period.

(b) A failure by Tenant to observe and perform any other terms or conditions of this Lease to be observed or performed by Tenant, where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that, if such default is of a nature that cannot be reasonably cured within such thirty (30) day period, no default shall exist so long as Tenant has commenced cure within such thirty (30) day period and diligently pursues same to completion within ninety (90) days.

(c) The making by Tenant of any assignment for the benefit of creditors, an adjudication that Tenant is bankrupt, insolvent, or unable to pay its debts; the filing by or against Tenant of a petition in bankruptcy or of a petition for reorganization or arrangement under any law relating to bankruptcy (unless, in the case of a petition filed against Tenant, the same is dismissed within sixty (60) days after the filing thereof); the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located in the Leased Space or of Tenant’s interest in this Lease (unless possession is restored to Tenant within thirty (30) days after such appointment); or the attachment, execution or levy against, or other judicial seizure of, substantially all of Tenant’s assets located in the Leased Space or of Tenant’s interest in this Lease (unless the same is discharged within thirty (30) days after issuance thereof).

22.

REMEDIES.

Upon the occurrence of any Event of Default by Tenant:

(a) Landlord may perform for the account of Tenant any such act, the omission of which constituted an Event of Default by Tenant and immediately recover as Additional Rent any expenditures made and the amount of any obligations incurred in connection therewith, plus interest at the Default Rate from the date the obligations are incurred by Landlord until payment therefor to Landlord, whether before or after entry of judgment and issuance of execution thereon.

(b) Landlord may accelerate all Minimum Annual Rent and Additional Rent due for the balance of the Term of this Lease and declare the same to be immediately due and payable. In determining the amount of any future payments due Landlord relating to Operating Expenses and/or Real Estate Taxes, Landlord shall make such determination based upon the most recent estimates of Operating Expenses and/or Real Estate Taxes available.

(c) Landlord, at its option, may serve notice upon Tenant that this Lease and the then unexpired term thereof shall cease and expire and become absolutely void on the date specified in such notice, to be not less than five (5) days after the date of such notice without any right on the part of the Tenant to save the forfeiture by payment of any sum due or by the performance of any term or condition broken; and, thereupon and at the expiration of the time limit in such notice, this Lease and the Term hereof, as well as the right, title and interest of the Tenant hereunder, shall wholly cease and expire and become void in the same manner and with the same force and effect (except as to Tenant’s liability) as if the date fixed in such notice were the date herein granted for expiration of the Term of this Lease. Thereupon, Tenant shall immediately quit and surrender to Landlord the Leased Space, and Landlord may enter into and repossess the Leased Space by summary proceedings, detainer, ejectment or otherwise and remove all occupants thereof and, at Landlord’s option, any property thereon, without being liable to indictment, prosecution or damages therefor. No such expiration or termination of this Lease shall relieve Tenant of its liability and obligations under the Lease, whether or not the Leased Space shall be relet.

(d) Landlord may, at any time after the occurrence of any Event of Default, re-enter and repossess the Leased Space and any part thereof and attempt in its own name, as agent for Tenant if this Lease not be terminated, or on its own behalf if this Lease be terminated, to relet all or any part of the Leased Space for and upon such terms and to such persons and for such period or periods as Landlord, in its sole discretion, shall determine, including a term beyond the termination of this Lease; and Landlord shall not be required to accept any tenant offered by Tenant or observe any instruction given by Tenant about such reletting. For the purpose of such reletting, Landlord may decorate or make repairs, changes, alterations or additions in or to the Leased Space to the extent deemed by Landlord desirable or convenient; and the cost of such decoration, repairs, changes, alterations or additions shall be charged to and be payable by Tenant as Additional Rent hereunder, as well as any reasonable brokerage and attorneys fees incurred by Landlord; and any sums collected by Landlord from any new tenant obtained shall be credited against the balance of the rent due hereunder as aforesaid. Tenant shall pay to Landlord monthly, on the days when the rent would have been payable under this Lease, the amount due hereunder less the amount obtained by Landlord from such new tenant.

(e) Landlord shall have the right of injunction, in the event of a breach or threatened breach by Tenant of any of the terms and conditions hereof, to restrain the same and the right to invoke any remedy allowed by law or in equity, whether or not other remedies, indemnities or reimbursements are herein provided. The rights and remedies given to Landlord in this Lease are distinct, separate and cumulative remedies; and no one of them, whether or not exercised by Landlord, shall be deemed to be in exclusion of any of the others.

(f) In the event of the occurrence of an Event of Default hereunder, Landlord shall have the right to change the locks on the Leased Space and exclude Tenant therefrom, and to discontinue all or part of the services and facilities provided to Tenant under this Lease or otherwise, which-action shall not be deemed an eviction. Such action may be taken, however, only upon five (5) days prior notice to Tenant, and Tenant hereby releases Landlord from any liability for any damages sustained by Tenant or its property as a result of the same.

(g) If Tenant has paid accelerated rent to Landlord and Landlord thereafter re-lets any portion of the Leased Space, any sums collected by Landlord from any new tenant obtained in excess of the cost of decoration, repairs, changes, alterations or additions, and any reasonable brokerage and attorneys fees incurred by Landlord in connection with such re-letting, to the extent the same exceed all other damages incurred by Landlord as a result of Tenant’s default, shall be paid to Tenant if, as and when received by Landlord from the replacement tenant, but in no event shall the amount to be paid to Tenant by Landlord exceed the amount of accelerated rent and other damages paid by Tenant to Landlord.

(h) Following an Event of Default, Landlord agrees not to unreasonably withhold, delay or condition (including, for example, the requirement of any back-rent payments by Tenant) its consent to any subtenants or assignees which Tenant may propose for all or any portion of the Leased Space provided that Landlord’s acceptance of any such subtenant or assignee shall not be deemed to cure Tenant’s default nor otherwise relieve Tenant of its obligations hereunder, unless Landlord otherwise agrees in writing. Any rent paid as a result of any such assignment or sublease shall be applied in accordance with subsection (g) above.

23.

CONFESSION OF JUDGMENT FOR POSSESSION IN LIMITED CIRCUMSTANCE.

If Tenant fails to vacate the Leased Premises upon termination of this Lease or an Event of Default under Section 21(a) shall have occurred, Landlord shall have the further remedy of confession of judgment for possession:

ANY PROTHONOTARY OR ATTORNEY OF ANY COURT OF RECORD MAY APPEAR FOR TENANT IN ANY COMPETENT COURT TO CONFESS JUDGMENT IN EJECTMENT AGAINST TENANT AND ALL PERSONS CLAIMING UNDER TENANT, AND A JUDGMENT FOR THE RECOVERY BY LANDLORD OF POSSESSION MAY ISSUE FORTHWITH WITHOUT ANY PRIOR WRIT OR PROCEEDINGS WHATSOEVER. IF FOR ANY REASON AFTER SUCH ACTION SHALL HAVE BEEN COMMENCED, IT SHALL BE CANCELED OR SUSPENDED AND POSSESSION OF THE LEASED SPACE REMAINS IN OR IS RESTORED TO TENANT, LANDLORD SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT OR TERMINATION OF THIS LEASE OR ANY RENEWAL OR EXTENSION HEREOF, TO BRING ONE

OR MORE ACTIONS IN CONFESSION OF JUDGMENT IN EJECTMENT AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE LEASED SPACE. IF IN ANY ACTION TO CONFESS JUDGMENT IN EJECTMENT, LANDLORD SHALL CAUSE TO BE FILED IN SUCH ACTION AN AFFIDAVIT SETTING FORTH THE FACTS NECESSARY TO AUTHORIZE THE ENTRY OF JUDGMENT AND IF A TRUE COPY OF THIS LEASE (AND THE TRUTH OF THE COPY STATED IN SUCH AFFIDAVIT SHALL BE SUFFICIENT PROOF) BE FILED IN SUCH ACTION, IT SHALL NOT BE NECESSARY TO FILE THE ORIGINAL AS A WARRANT OF ATTORNEY, ANY LAW, RULE OF COURT, CUSTOM OR PRACTICE TO THE CONTRARY NOTWITHSTANDING. TENANT EXPRESSLY RELEASES TO LANDLORD, AND TO ANY AND ALL ATTORNEYS WHO MAY APPEAR FOR TENANT, ALL ERRORS IN THE SAID PROCEEDINGS, AND ALL LIABILITY THEREFOR.

24.

WAIVER.

The failure or delay on the part of either party to enforce or exercise at any time any of the terms and conditions of this Lease shall in no way be construed to be a waiver thereof, nor in any way to affect the validity of this Lease or any part hereof, or the right of such party to thereafter enforce each and every such term or condition. No waiver by either party of any breach of this Lease shall be held to be a waiver of any other or subsequent breach. The receipt by Landlord of rent or the payment by Tenant of rent at a time when a default exists under this Lease shall not be construed as a waiver of such default. The receipt by Landlord of a lesser amount than the rent due shall not be construed to be other than a payment on account of the rent then due, nor shall any statement on Tenant’s check or any letter accompanying Tenant’s check be deemed an accord and satisfaction, and Landlord may accept such payment without prejudice to Landlord’s right to recover the balance of the rent due or to pursue any other remedies provided in this Lease. No act or thing done by this Lease shall be deemed an acceptance or a surrender of the Leased Space, and no agreement to accept such a surrender shall be valid unless in writing and signed by the party against whom enforcement is sought.

25.

QUIET ENJOYMENT.

If and so long as Tenant pays the rent reserved hereunder and observes and performs all the terms and conditions on Tenants part to be observed and performed hereunder, Tenant shall and may peaceably and quietly have, hold and enjoy the Leased Space for the entire Term hereof, subject to all of the provisions of this Lease.

26.

FORCE MAJEURE.

Time periods for performance of each party’s obligations (including without limitation construction obligations) under any of the terms of this Lease shall be extended for periods of time during which performance is prevented due to circumstances beyond the performing party’s control, including without limitation, embargoes, governmental regulations, act of God, war or other strife, shortages or unavailability of materials or equipment which are “special order items” described in the Core and Shell Project Construction Documents, TI Plans or Change Orders, strikes, lockouts, adverse weather conditions, bankruptcy or breach of contract by a subcontractor and Tenant Delays as defined in the Work Letter (collectively, “Force Majeure”). Force Majeure events shall not, however, excuse any party’s failure to perform a monetary obligation which has arisen.

27.

SUCCESSORS.

The respective rights and obligations provided in this Lease shall bind and shall inure to the parties hereto, and their successors and permitted assigns.

28.

LANDLORD’S LIABILITY.

Landlord’s responsibility under this Lease shall be limited to its interest in the Leased Space and in the Building, and no members of Landlord’s partnership shall be personally liable hereunder. Tenant agrees to look solely to Landlord’s interest in the Leased Space and in the Building for the collection of any judgment, and, in entering any such judgment, the person entering the same shall request the prothonotary to xxxx the judgment index accordingly. If the Leased Space or the Building is transferred or conveyed, Landlord shall be relieved of all covenants and obligations under this Lease thereafter accruing, provided that notice of said transfer or conveyance is given to Tenant by Landlord. The liability of Lot 11 Owner as Landlord under this Lease is further limited in the manner and to the extent provided in the second paragraph of the Background section of this Lease.

29.

SUBORDINATION.

Landlord represents the mortgage to National Penn Bank listed on Exhibit “F” attached hereto (the “National Penn Mortgage”) currently encumbers the Building and that no “Mortgage” (hereafter defined) other than the National Penn Mortgage currently encumbers the Building, any part thereof, or the land on which it is situate. Within thirty (30) days following the Effective Date, Landlord shall obtain for the benefit of Tenant a subordination, non-disturbance and attornment agreement which is reasonably satisfactory to Tenant with respect to the National Penn Mortgage. Upon delivery of a non-disturbance and attornment agreement which is reasonably satisfactory to Tenant, this Lease is, and all of Tenant’s rights hereunder are and shall always be, subject and subordinate to any such mortgage, leases of Landlord’s property (in sale-leaseback) pursuant to which Landlord has or shall retain the right of possession of the Leased Space (and/or the Building) or security instruments (collectively called “Mortgage”) that

may hereafter be placed upon the Leased Space or the Building, or any part thereof and all advances made or to be made thereunder and extensions thereof, and if the holder of any such interest (“Mortgagee”) forecloses or extinguishes Landlord’s rights in the Building or Leased Space, Tenant shall attorn to and recognize any such holder as the successor Landlord under this Lease. The aforesaid provision shall be self-operative and no further instrument or document shall be necessary unless required by any such Mortgagee or purchaser. Notwithstanding anything to the contrary set forth above, any Mortgagee may at any time subordinate its Mortgage to this Lease, without Tenant’s consent, by execution of a written document subordinating such Mortgage to this Lease to the extent set forth therein, thereupon this Lease shall be deemed prior to such Mortgage. Should Landlord or any Mortgagee or purchaser desire confirmation of either such subordination or such attornment, as the case may be, Tenant upon written request, and from time to time, will execute and deliver without charge and in form reasonably satisfactory to Tenant, Landlord, to the Mortgagee or the purchaser all instruments and/or documents that may be required to acknowledge such subordination and/or agreement to attorn, in recordable form within ten (10) business days following a request therefor from Landlord. The foregoing subordination and attornment provisions are subject to the Mortgagee’s agreement that such Mortgagee agrees to recognize this Lease and to allow Tenant to remain in possession of the Leased Space and exercise all of its rights under the Lease so long as Tenant does not suffer an Event of Default under this Lease and this Lease or Tenant’s right of possession is not terminated in accordance with the terms of this Lease.

30.

RULES AND REGULATIONS.

Tenant agrees to comply with the rules and regulations established by Landlord from time to time, which Landlord agrees will be applied uniformly to all tenants; provided, however, that none of such rules and regulations materially and adversely affect Tenant’s rights hereunder or the operation of Tenant’s Business from the Leased Space, and Tenant is afforded a reasonable time from notice thereof to achieve compliance therewith. The existing rules and regulations are attached hereto as Exhibit E.

31.

GOVERNING LAW.

This Lease shall be governed by and construed in accordance with the laws of the state in which the Building is located.

34.

BROKERS.

Tenant represents and warrants to Landlord that Tenant has not dealt with any broker, firm, company or person in connection with the negotiation for or the obtaining of this Lease, and each party shall indemnify, defend and hold harmless the other from and against any claim by any person claiming a commission or other form of compensation by virtue of having dealt with such party with regard to this Lease, and any attorneys fees or other expenses incurred by the other party in connection therewith.

35.

SIGNS.

Tenant shall not, without the prior written consent of Landlord, paint, place or erect any sign on the exterior doors or walls of the Leased Space or of the Building or Center. Subject to applicable zoning requirements and Landlord and Tenant’s mutual agreement on sign graphics not to be unreasonably withheld, Tenant shall have the right to maintain existing signs on the Land as follows: (a) two monument signs of the size and at the current location as exist and face Stockton Drive, each of which monument signs have columns at each side which are approximately 19.5 inches wide and 63.5 inches high, which columns surround a monument approximately 97 inches wide by 51.5 inches high; and (b) a building entry sign a maximum of

36 inches wide by 22 inches high at the Building’s main entry door. Landlord shall install at its expense vinyl lettered signs on any unused entry doors at the front of the Building indicating that such doors are not entrances to the Building. Tenant shall have the right, at Tenant’s cost and expense, change the center insert in the existing monument sign to an insert approximately 8 feet wide and 5 feet high, subject to compliance with the recorded covenants at the Center.

36.

SECURITY DEPOSIT.

(a) Landlord is in possession of the security deposit under the Original Lease, in the sum of $137,000.00, which shall continue to be held by Landlord as security for the faithful performance of all the terms and conditions of this Lease (“Security Deposit”). Should the Tenant breach any of the terms and conditions of this Lease which continues beyond any applicable cure period and required notice, Landlord shall have the right, at any time, to apply the Security Deposit or any part thereof, for the purpose of curing any such default or for the purpose of reimbursing Landlord for any damage or costs occasioned by such default, but the right of Landlord to apply the Security Deposit shall not affect any other remedies available to Landlord under this Lease or under applicable law. If the Security Deposit, or any part thereof, is so applied by Landlord, Tenant shall, within ten (10) days after demand, deposit additional funds with Landlord to restore the Security Deposit, and failure to do so shall constitute an event of default under this Lease.

(b) If the Tenant shall have complied with all material terms and conditions of this Lease at the expiration of this Lease, the Security Deposit (without interest and amounts properly withdrawn by Landlord and not refunded by Tenant) shall be refunded to Tenant within thirty (30) days after the expiration or sooner termination of this Lease (including without limitation permitted terminations hereunder and terminations due to Landlord’s default which continue beyond applicable grace and cure periods following notice where applicable); provided, however, that Tenant first shall have vacated the Leased Space and surrendered possession thereof to the Landlord by delivery of keys, in accordance with the Lease provisions and shall have returned the Leased Space to Landlord in the condition required hereunder.

(c) Nothing herein contained shall require Landlord to hold the sums so deposited as a trust fund, nor establish any relationship other than that of debtor and creditor with respect to said funds so deposited.

(d) If Landlord shall assign or otherwise transfer its interest in this Lease, Landlord shall transfer the Security Deposit to the assignee or other transferee of such interest (with like obligation to transfer to any subsequent assignee or other transferee), and upon such transfer, Landlord shall be released and relieved from all liability and/or responsibility with respect to this Security Deposit and/or the return or application thereof.

37.

USE OF INFORMATION IN ADVERTISING.

Landlord and any agent employed by Landlord shall be permitted to utilize the name of Tenant and any occupant or user of the Leased Space, and other general information about the Tenant and such occupant or user, and the terms of this Lease, in advertising and promotional material utilized by them.

The title to paragraphs of this Lease are for convenience of reference only, and are not to be construed as defining, limiting or modifying the scope or intent of any of the terms and conditions of this Lease.

39.

ENTIRE AGREEMENT.

This Lease contains all covenants and agreements between Landlord and Tenant relating in any manner to the rental, use and occupancy of the Leased Space and Tenant’s use of the Building and other matters set forth in this Lease.

42.

SELF-HELP.

(a) With the exception of Landlord’s obligations under the Work Letter (with respect to which Tenant’s self-help rights shall be governed by the terms of the Work Letter), if Landlord fails to fulfill its obligations under this Lease, Tenant shall notify Landlord of such non-performance. Except in the case where immediate response is required to avoid physical damage to the Leased Space or persons or Tenant’s property therein, Landlord shall have thirty (30) days to cure such nonperformance. If Landlord fails to complete cure within such thirty (30) days after receipt of such notice from Tenant, Tenant shall have the right, but not the obligation, to carry out such activities on behalf of Landlord so as to cure such nonperformance. Landlord shall reimburse Tenant for all reasonable costs, fees and expenses incurred by Tenant in connection with performing such cure. Such reimbursement shall be made within fifteen (15) days after written demand by Tenant, which demand shall be accompanied by appropriate invoices or other materials to substantiate the amount for the requested reimbursement. If Landlord fails to pay

Tenant the amount requested within said fifteen (15) day period, such unpaid amounts shall accrue interest at the Default Rate which shall continue to accrue on any judgment obtained by Tenant against Landlord for recovery of such unreimbursed amounts. Notwithstanding the foregoing rights, Tenant shall not be entitled to set-off such amounts against Rent due hereunder, and Tenant hereby expressly waives such right, unless and until Tenant shall have obtained a final judgment against Landlord with respect to Landlord’s obligation under the Lease which Tenant alleges that Landlord failed to perform, and such right of set-off shall be applicable only to the amount of the judgment not paid within thirty (30) days and may be asserted by Tenant against installments of Rent thereafter coming due.

(b) Amounts due from Landlord to which the Default Rate has been applied shall continue to accrue interest at the Default Rate after entry of judgment and issuance of execution thereon until paid in full.

MEMORANDUM OF LEASE.

Tenant, at its expense, shall be entitled to record a memorandum of lease which Landlord shall execute and acknowledge. Concurrently with the execution of this Lease, Tenant and Landlord agree to execute such memorandum of lease along with a termination thereof, in form substantially similar to the memorandum of lease recorded and termination delivered into escrow in accordance with the Original Lease, which memorandum shall supersede in its entirety the memorandum recorded in connection with the Original Lease. The termination of such memorandum of lease shall be held in escrow by Riley, Riper, Xxxxxx & Xxxxxxxxx, as escrow agent, until termination of this Lease, pursuant to a separate escrow agreement substantially similar to the escrow agreement executed in accordance with the Original Lease. In the absence of such escrow agreement, the party designated as escrow agent shall hold such termination until the earlier of (a) receipt of a court order directing release of said termination or (b) written instructions from Landlord and Tenant directing the release of said termination. Landlord shall cause its affiliates which own the Adjacent Land (as defined in Section 47 below) to execute and acknowledge the foregoing memorandum and termination with respect to the Adjacent Land and Southwest Parcel.

44.

LANDLORD REPRESENTATIONS AND WARRANTIES.

(a) Landlord, to induce Tenant to enter into this Lease, represents, warrants and agrees, as of the date first set forth above and the Commencement Date, as follows, which representations and warranties shall survive until one (1) year after the New Building and New Leased Space are Substantially Completed:

(i) Title to the Property. To Landlord’s Knowledge, Landlord owns the Land upon which the Existing Building has been constructed, and Xxx 00 Xxxxx xxxx Xxx 00, and each and has good and marketable title of record thereto, free of any liens or encumbrance except for the Permitted Title Exceptions described on Exhibit F hereto. Landlord’s ownership of the Land has never been challenged. No parties other than Landlord are

required to execute or consent to this Lease. Landlord represents and warrants to Tenant that the Permitted Title Exceptions will not materially interfere with Tenant’s use of the Leased Space for Tenant’s intended use and that the Permitted Title Exceptions will not interfere with the construction of the New Building in accordance with the terms of the Work Letter.

(ii) No Third Party Rights. There are no options, licenses, leases, rights of first refusal, contracts for the sale of the Real Estate (including conditional sales agreements) or similar arrangements respecting the Real Estate other than as are to be entered with Tenant.

(iii) Condemnation. Landlord has not received any notice or other communication from any governmental unit or other body having the power of eminent domain indicating that any part of the Land or other portion of Eagleview Corporate Center has been, will or may be condemned.

(iv) Proceedings. No action, suit, or proceeding currently is pending against the Real Estate or, to Landlord’s Knowledge, any other portion of Eagleview Corporate Center in any court or before any board, commission agency or other governmental instrumentality. Landlord has not received written notice of any such threatened action, suit, or proceeding.

(v) Assessments: Public Improvements. No assessments or notice of assessments for public improvements have been made against the Land prior to the date of this Lease which have not been paid, other than impact fees which will be paid by Landlord, and no work has been commenced on new public improvements authorized by ordinances enacted prior to the date hereof which will result in an assessment against the Land.

(vi) Zoning and Approvals. The Land is zoned planned commercial/industrial. All subdivision and land development approvals necessary for the creation of the new Lot 10 as a separate lot, consisting of the existing Lots 10 and 11, with direct access to a public road (collectively “Approvals”) will have been obtained and will be in full force and effect as of the Commencement Date for the New Leased Space. Landlord is in full compliance with all Approvals and, to Landlord’s Knowledge, no condition or state of facts now exists which, with the giving of notice or expiration of applicable time period, could cause the invalidation, termination or revocation of any of the Approvals. Landlord will obtain such approvals to combine the Land into a single, separate lot with direct access to public roads which, when obtained, shall be part of the Approvals.

(vii) Flood Plain. To Landlord’s Knowledge, no portion of the Land is located within a special flood hazard area as documented in the “Department of Housing and Urban Development, Federal Insurance Administration Special Flood Hazard Area Maps.”

The Environmental Report covers the Land, and, to Landlord’s Knowledge, no facts or circumstances have changed at the Land which would make any potion of the Environmental Report incorrect or misleading. In the event there is found, through a Phase 1 environmental site assessment obtained by Tenant on Xxx 00 (xxx “Xxx 00 Xxxxx 0 Report”), any adverse environmental condition which in Tenant’s reasonable judgment will preclude its use of the New Building for Tenant’s Business, or which will expose Tenant to liability for remediation of existing environmental hazards identified in the Xxx 00 Xxxxx 0 Report, which liability Landlord will not assume in a manner satisfactory to Tenant, then Tenant may terminate this Lease by written notice delivered to Landlord not later than two (2) business days after receipt of the Xxx 00 Xxxxx 0 Report, provided, however, that in such event, the Original Lease shall be immediately reinstated as if this Lease were not in existence.

(B) Compliance; Permits.

(ix) Utilities. The following utilities currently service the Real Estate (or are available to service the Land with appropriate connections): water, sewer, gas, telephone, electricity and conduits for fiber optics and cable. All approvals required for any necessary connections have been obtained and remain in full force and effect. All such utilities are available currently at the Building and are available without any limitation or allocation imposed by the utility provider or applicable governmental authorities with the exception of sewer effluent limitations.

(x) Covenants. The Amended and Restated Declaration of Easements and Protective Covenants recorded in Deed Book 2074 at Page 240 as amended by a Supplement and Clarification recorded in Deed Book 2363, page 499, a First Amendment recorded in Deed Book 2596, page 550, a Second Amendment recorded in Deed Book 3590, page 1986, a Third Amendment recorded in Deed Book 3672, page 579 and a Fourth Amendment recorded on Deed Book 4177, page 2306, a Fifth Amendment recorded in Record Book 4206 Page 1534, a Sixth Amendment recorded in Record Book 4365 Page 649, a Seventh Amendment recorded in Record Book 4744 Page 0278, and an Eighth Amendment recorded in Record Book 7006, page 2299 (collectively, “Declaration”) constitutes all of the protective covenants or similar agreements which effect Eagleview Corporate Center. Landlord represents and covenants that no private agreements exist which materially and adversely affect Tenant’s rights under this Lease or an owner’s rights under the Declaration, including the ability to seek enforcement thereof, nor will Landlord hereafter enter into any such agreement.

(xi) Discovery of Facts. If, prior to the Commencement Date, Landlord acquires actual knowledge of any fact which would be required to be disclosed by Landlord to render its representations and warranties true, correct and complete, in all material respects, Landlord promptly shall disclose such fact to Tenant.

(b) For purposes of this Section 44, the term (and similar terms) “to Landlord’s Knowledge” shall mean to the best knowledge of Landlord’s President and Vice President of Commercial Sales and Leasing (including without limitation knowledge deemed to be charged to Landlord by virtue of items and facts disclosed in the reports of consultants in Landlord’s possession wherever located) such statement or fact is true and correct and such persons possess no information which make such statement or fact incomplete or misleading.

45.

RENEWAL OPTION.

(a) Tenant shall have the right and option to extend the term of this Lease for two (2) consecutive renewal terms, the first of which shall be of a duration of between three (3) and seven (7) years, as determined by Tenant and as stated in Tenant’s notice of its exercise of its renewal option, and the second of which shall be of a duration equal to ten (10) years reduced by the number of years in the first renewal term as elected by Tenant. The first renewal term, if exercised, shall commence on the day immediately following the expiration of the initial Term hereof, and the second renewal term, if exercised, shall commence on the date immediately following the expiration of the first renewal term. The option to extend, as well as the commencement of each renewal term, shall be conditioned on no uncured Events of Default by Tenant then existing.

(b) Tenant shall exercise each renewal option only by delivering written notice of same to Landlord not later than one (1) year prior to the expiration of the then current term. Tenant’s failure to timely exercise an option shall be deemed a waiver of all rights under this Section, in which event this Lease shall terminate upon expiration or earlier termination of the then current term.

(c) Each renewal term, if exercised, shall be upon all of the terms and conditions of this Lease, except for provisions which, by their nature, are limited to the Initial Term and for the change in Minimum Annual Rent which (i) for the first renewal term, if exercised, shall be the greater of the rate per rentable square foot during the final year of the initial Term, or the FMRV determined in accordance with subsection (d) below and (ii) for the second renewal term, if exercised, shall be the greater of the rate per rentable square foot during the final year of the first renewal term, or the FMRV determined in accordance with subsection (d) below.

(d) Fair Rental Value Calculation. The “FMRV” shall mean the fair market rental rate per square foot of rentable area per year, calculated at the time of the determination of the FMRV and based on leases within Xxxxxxx County for comparable space under comparable terms within comparable buildings at the time in question. Subject to the foregoing, the FMRV shall be determined as follows:

(i) Not later than three (3) months nor sooner than six (6) months prior to the commencement of a renewal term, Landlord shall notify Tenant in writing of Landlord’s estimate of the FMRV. Within ten (10) business days following Landlord’s notice of the FMRV, Tenant, by written notice to Landlord, either will accept Landlord’s statement of the FMRV or notify Landlord of Tenant’s estimate of the FMRV, if different from that set forth in Landlord’s notice. In the absence of such timely notice by Tenant to Landlord, Tenant will be deemed to have accepted Landlord’s statement of the FMRV. If Tenant shall furnish a counter-estimate of the FMRV, Landlord, by written notice to Tenant within ten (10) business days after Landlord’s receipt of Tenant’s estimate, either may accept Tenant’s estimate in writing or, without prejudice to any position, suggest alternative figures for the FMRV which are greater than Tenant’s estimate thereof and less than Landlord’s initial statement. In the absence of such timely notice by Landlord to Tenant, Landlord will be deemed to have accepted Tenant’s statement of FMRV. If Landlord and Tenant shall not have an agreement as to the FMRV within forty-five (45) days following Tenant’s written notice to Landlord exercising a renewal right, FMRV shall be determined by appraisal as set forth in subsection (ii) below.

(ii) If the FMRV is to be determined by appraisal, such determination shall be by an appraiser who is a member of the American Institute of Real Estate Appraisers or its successor organization holding the M.A.I. designation, and who is agreed upon by Landlord and Tenant. If Landlord and Tenant are unable to agree upon an appraiser within the time period specified in subsection (i) above, then, within five (5) business days thereafter, each shall appoint a M.A.I. appraiser and the FMRV shall be the FMRV determined by such appraisers (and the parties shall request the appraisers to make such determination within five (5) business days of such appointment) or the average thereof if their respective appraisals differ by ten percent (10%) or less. If either party shall fail to appoint an appraiser within the time provided, the FMRV determined by the appraiser timely appointed shall be the FMRV. If the appraisals delivered by the appraisers appointed by Landlord and Tenant differ by more than ten percent (10%), the appraisers so appointed shall appoint a third M.A.I. appraiser and the FMRV shall be the average of the appraisal delivered by the third appraiser and whichever of the appraisals previously delivered by the appraisers appointed by Landlord and Tenant is closer to the appraisal of the third appraiser. If the two appraisers are unable to agree upon a third appraiser within ten (10) days from the date the later of their two appraisals is delivered, such appointment, on application by either Landlord or Tenant, will be made by the then President of the Real Estate Board for Xxxxxxx County or, if such person is unwilling or unable to make such appointment, by the American Arbitration Association or its successor organization acting through its office in Philadelphia or by its office located closest to Philadelphia. Landlord and Tenant each shall pay the fees and expenses of the respective appraiser appointed by each of them and shall pay in equal shares the fees and expenses of the appraiser mutually agreed upon by Landlord and Tenant, or as may be appointed by the first two appraisers, the then President of the Real Estate Board for Xxxxxxx County or the American Arbitration Association or its successor, as applicable.

(iii) The determination of FMRV in accordance with this Section shall be conclusive and binding on Landlord and Tenant.

46.

LANDLORD’S SUBORDINATION.

Landlord agrees to execute a commercially reasonable subordination agreement pursuant to which Landlord agrees to subordinate any statutory or common law landlord’s lien to a security interest in Tenant’s personal property located in the Leased Space which is granted to a bank or other financial institution acquiring such security interest to secure a credit facility provided to Tenant required by Tenant to finance acquisition of Tenant’s personal property or working capital.

47.

EXPANSION OPTION FOR ADJACENT BUILDING

(a) For the purpose of this Section, the term “Landlord” shall mean either Landlord or any affiliate of Landlord which owns property adjacent to the Building, such adjacent property being a lot consisting of approximately 9 acres, more or less at the end of Arrowhead Drive with frontage on the Pennsylvania Turnpike, (“Adjacent Land”), on which Adjacent Land Landlord expects to obtain development approval for a building of approximately 62,000 rentable square feet designated as “4” on the plan attached hereto as Exhibit G (the “ROFO Building”), and the “Southwest Parcel” (as defined in subsection (b) below), as applicable. If Landlord desires to lease or sell all or a portion of the ROFO Building, Landlord shall notify Tenant of such decision in writing (“Availability Notice”), and within ten (10) business days thereafter, Tenant shall notify Landlord in writing whether it desires to negotiate a lease or purchase of the ROFO Building from Landlord. If Tenant so notifies Tenant that it desires to negotiate a lease or purchase of the ROFO Building, Landlord shall provide to Tenant a non-binding, written lease or sale proposal, as applicable (“Landlord’s Term Sheet”). Tenant shall, within ten (10) business days following receipt of Landlord’s Term Sheet, advise Landlord whether it desires to enter into a lease or agreement of sale and purchase on the terms contained in the Landlord’s Term Sheet. If (A) Tenant rejects or fails to respond to the Availability Notice or Landlord’s Term Sheet within the applicable period specified above, or (B) Landlord and Tenant do not execute a lease or agreement of sale and purchase, as applicable, for the ROFO Building within thirty (30) days after Tenant’s receipt of Landlord’s Term Sheet, Landlord shall be entitled to lease or sell the ROFO Building, or any portion thereof, free and clear of any rights of Tenant under this Section. A condition to Tenant’s exercise of its rights under this Section shall be that no outstanding notice of default exists under this Lease at each time of exercise.

(b) In addition, the land located to the west of the Land designated as “Southwest Parcel” on Exhibit G (“Southwest Parcel”) will support the development of three buildings located thereon as depicted on Exhibit G, although Landlord has not yet obtained plan approvals for such buildings. At such time as the remaining square footage available to be leased or sold on the Southwest Parcel, whether in buildings constructed or available to be constructed, is reduced to 80,000 square feet (collectively the “Minimum ROFR Availability”), and if at such time Tenant has not leased or purchased any portion of the ROFO Building, Tenant shall have a right of first refusal to lease any space within a building which contains or will contain the Minimum ROFR Availability (the “ROFR Space”) or purchase such building (a “ROFR Building”) in accordance with the following procedures.

(i) If Landlord desires to issue a proposal to sell or lease the ROFR Space or an ROFR Building on terms acceptable to Landlord, or Landlord has received a proposal for purchase or lease which Landlord desires to accept, Landlord shall notify Tenant of such decision in writing (“Offer Notice”) and shall offer to Tenant the opportunity to lease the ROFR Space or purchase the ROFR Building described in such Offer Notice on the same terms and conditions set forth in the Offer Notice. The Offer Notice shall be accompanied by a written lease or sale proposal from Landlord and shall otherwise include all relevant information as to the terms of such offer. Tenant shall have fifteen (15) business days after receipt of the Offer Notice to notify Landlord in writing that it will lease the ROFR Space or purchase the ROFR Building from Landlord.

(ii) If (A) Tenant rejects or fails to respond to the Offer Notice within the applicable period specified in subsection (i) above, or (B) Landlord and Tenant, despite reasonable, good faith efforts, do not execute a lease for the ROFR Space or agreement of sale and purchase for the ROFR Building, as applicable, within thirty (30) days after Tenant’s exercise of its rights hereunder, Landlord shall be entitled to lease the ROFR Lease or sell the ROFR Building pursuant to the applicable Offer Notice, upon substantially the same terms and conditions set forth in the Offer Notice; provided, however, that no such lease or sale shall be made on other terms materially less favorable to Landlord than the terms set forth in the Offer Notice. If Landlord has not so leased the ROFR Space or sold the ROFR Building, as applicable, on the terms specified in the Offer Notice (or on terms materially more favorable to Landlord) within nine (9) months from delivery of the Offer Notice with respect to a sale, and within six (6) months from delivery of the Offer Notice with respect to a lease, Landlord shall not thereafter offer to lease the ROFR Space or sell the ROFR Building, as applicable, to any party (including the offeror named in the Offer Notice) without again complying with the provisions of this Section 47(b). All terms of this Section 47 shall apply to such revised Offer Notice, including Tenant’s opportunity to respond to the revised Offer Notice within the applicable period specified above. If Landlord executes the lease or agreement of sale and purchase with a third party contemplated by the Offer Notice within the parameters permitted by this subsection, Tenant’s rights hereunder shall be null and void as to the ROFR Space so leased or the ROFR Building so sold, but, in the case of a lease of less than the entire ROFR Building, shall continue to apply to the balance of the ROFR Building not leased. Otherwise, Tenant’s rights hereunder shall expire with the termination of this Lease, as renewed.

(iii) Landlord covenants that it shall not develop, nor permit its affiliates to develop, the balance of the Center which Landlord or such affiliate owns in any manner during the period that this subsection (b) remains in effect, which could result in the buildings available to be developed on the Southwest Parcel being less than 80,000 square feet.

(c) Condition to Exercise of Rights. A condition to Tenant’s exercise of its rights under this Section shall be that no outstanding notice of a default by Tenant exists under this Lease at each time of exercise. The failure of such condition with respect to any one exercise of Tenant’s rights shall not preclude Tenant’s further exercise of its rights hereunder.

(d) Any provision in this Section 47 with respect to the right to purchase the ROFO Building or ROFR Building shall be inapplicable with respect to any portfolio sale of 500,000 square feet or more of Landlord’s and its affiliates’ buildings in the Center, but the terms and conditions of this Lease, including Tenant’s rights under this Section 47, shall survive any portfolio sale.
