1.                                      LEASE:

Landlord has leased the Premises to Tenant for the Term.

2.                                      FIXED BASIC RENT:

Tenant will pay Landlord the Fixed Basic Rent. The Fixed Basic Rent payable for the entire Term will be the aggregate of the Annual Rate set forth in the Basic Lease Provisions and will be payable, in advance, on the first day of each calendar month during the Term at the Monthly Installments set forth in the Basic Lease Provisions, except that a proportionately lesser amount will be paid for the first month of the Term if the Term commences on a day other than the first day of the month.  Tenant will pay the first (1st) full monthly installment of Fixed Basic Rent upon Tenant’s execution and delivery of this Lease.  Tenant will pay Fixed Basic Rent, and any Additional Rent, to Landlord at Landlord’s address set forth in the first paragraph of this Lease, or at such other place as Landlord may designate in writing, without demand and without counterclaim, deduction or set off.

3.                                      USE AND OCCUPANCY:

Tenant will use the Premises solely for the Permitted Use.

Neither Tenant, nor anyone acting by or through Tenant, will generate, handle, dispose, store or discharge any hazardous substances or wastes as defined by Legal Requirements in, on or around the Premises, the Building or the Real Property in violation of any Legal Requirements (such actions collectively referred to as “Prohibited Actions”).  Tenant will defend, indemnify and hold Landlord harmless against any and all loss, cost, damage, liability or expense (including attorneys’ fees and disbursements) which Landlord may sustain as a result of any Prohibited Actions.

4.                                      CARE AND REPAIR OF PREMISES:

Tenant will not commit any act that damages the Premises or Building and will take good care of the Premises, and will comply with all Legal Requirements affecting the Premises or the Tenant’s use and/or occupancy of the Premises.  Landlord will, at Tenant’s expense, make all necessary repairs to the Premises.  Landlord will make all necessary repairs to the Common Facilities.  The cost of repairs to the Common Facilities will be included in Operating Costs, except where the repair has been made necessary by misuse or neglect by Tenant or Tenant’s agents, employees, contractors, invitees, visitors or licensees (collectively, “Tenant’s Agents”), in which event Landlord will nevertheless make the repair but Tenant will pay to Landlord, as Additional Rent, upon demand, the cost incurred by Landlord to complete such repairs.  All improvements made by Tenant prior to or after the commencement of the Term which are attached to the Premises will, at Landlord’s option, become the property of Landlord upon the expiration or sooner termination of this Lease.  At Tenant’s request, Landlord shall notify Tenant prior to any improvements made by Tenant whether Landlord will require such improvements to be removed upon the Expiration Date. Not later than the last day of the Term, Tenant will, at Tenant’s expense, remove from the Building all of Tenant’s personal property and those improvements made by Tenant which Landlord has not elected by notice to Tenant to retain as Landlord’s property, as well as all trade fixtures (other than built-in cabinet work), moveable partitions, workstation modules, telephone, computer, data and antenna wiring, cabling and related conduit and the like.  Tenant will repair all injury done by or in connection with the installation or removal of said property, improvements, wiring and the like; cap or terminate all telephone, computer and data connections at service entry panels in accordance with Legal Requirements; and surrender the Premises in as good condition as they were at the beginning of the Term, except for reasonable wear and damage by casualty or other cause not due to the misuse or neglect by Tenant and/or Tenant’s Agents.  All property of Tenant remaining on the Premises after the last day of the Term will be conclusively deemed abandoned and may be removed and discarded or stored at Tenant’s risk by Landlord, and Tenant will pay Landlord for the cost of such removal, discarding and/or storage. Notwithstanding anything contained herein to the contrary, Tenant shall remove all installations that are “non-standard office improvements”. For purposes hereof, “non-standard office improvements” shall mean raised flooring, interior staircases, vaults, elevators, modifications to the Building’s utility and mechanical systems and unusual configuration for first class office space that were not part of the Work (including Change Orders) as provided in Paragraph 20 and Exhibit C. Tenant shall repair any damage to the Premises resulting from such removal.

Tenant is responsible for all costs related to the repair and maintenance of any additional or supplemental HVAC systems, appliances and equipment serving exclusively the Premises or installed to meet Tenant’s specific requirements.  Tenant will purchase and maintain throughout the Term an annual full maintenance and service contract for this equipment and will forward a copy of each proposed contract to Landlord for its approval prior to signing it.

5.                                      ALTERATIONS, ADDITIONS OR IMPROVEMENTS:

Tenant will not, without first obtaining the written consent of Landlord, make any alterations, additions or improvements (collectively, “alterations”) in, to or about the Premises.  Unless the alterations affect the Common Facilities or Building Systems or would otherwise require a building permit, Landlord will not unreasonably withhold or delay its consent.  Building Systems include the life safety, plumbing, electrical, heating, ventilation and air conditioning systems in the Building.  Tenant may, upon prior notice to Landlord, perform minor cosmetic improvements, such as painting and wallpapering, without the prior consent of Landlord. As part of Landlord’s consent to Tenant’s alterations, upon Tenant’s request, Landlord shall state in writing whether Tenant will be required to remove such alterations upon the Expiration Date.

If Tenant shall request the consent or approval of Landlord to the making of any alterations or to any other thing, and Landlord shall seek and pay a separate fee for the opinion of Landlord’s counsel, architect, engineer or other representative or agent as to the form or substance thereof, Tenant shall pay Landlord, as Additional Rent, within 30 days after demand, all reasonable costs and expenses of Landlord incurred in connection therewith, including, in case of any alterations, costs and expenses of Landlord in reviewing plans and specifications.

6.                                      ASSIGNMENT AND SUBLEASE:

Tenant will not mortgage, pledge, assign or otherwise transfer this Lease or sublet all or any portion of the Premises in any manner except as specifically provided for in this Article 6:

a)                                      If Tenant desires to assign this Lease or sublease all or part of the Premises, the terms and conditions of such assignment or sublease will be communicated by Tenant to Landlord in writing no less than thirty (30) days prior to the effective date of such sublease or assignment.  Prior to such effective date, Landlord will have the option, upon notice to Tenant, to terminate the Lease, (i) in the case of subletting, solely as to that portion of the Premises to be sublet, or (ii) in the case of an assignment, as to all of the Premises, and in such event, Tenant will be fully released from its obligations with respect to the terminated space (“Recapture Space”) accruing from and after the effective date.  If Landlord terminates the Lease as to the Recapture Space, in no event will Landlord be liable for a brokerage commission in connection with the proposed assignment or sublet. If Landlord recaptures the Recapture Space, Tenant shall be responsible for fifty percent (50%) of the cost for all alterations required to separate the Recapture Space from the balance of the Premises, including, but not limited to, construction of demising walls and separation of utilities.

b)                                     In the event that the Landlord elects not to terminate the Lease as to the Recapture Space, Tenant may assign this Lease or sublet the whole or any portion of the Premises, subject to Landlord’s prior written consent, which consent will not be unreasonably withheld, conditioned or delayed, subject to the following terms and conditions and provided the proposed occupancy is in keeping with that of a first-class office building:

i)                                         Tenant will provide to Landlord the name, address, nature of the business and evidence of the financial condition of the proposed assignee or sublessee;

ii)                                      The assignee will assume, by written instrument, all of the obligations of the Tenant under this Lease, and a copy of such assumption agreement will be furnished to Landlord within ten (10) days of its execution.  No further assignment of this Lease or subletting all or any part of the Premises will be permitted;

iii)                                   Each sublease will provide that sublessee’s rights will be no greater than those of Tenant, and that the sublease is subject and subordinate to this Lease and to the matters to which this Lease is or will be subordinate, and that in the event of default by Tenant under this Lease, Landlord may, at its option, have such sublessee will attorn to Landlord provided, however, in such case Landlord will not (i) be liable for any previous act or omission of Tenant under such sublease or, (ii) be subject to any offset not expressly provided for in this Lease or by any previous prepayment of more than one month’s rent;

iv)                                  The liability of Tenant and each assignee will be joint, several and primary for the observance of all the provisions, obligations and undertakings of this Lease, including the payment of Fixed Basic Rent and Additional Rent through the entire Term, as the same may be renewed, extended or otherwise modified;

v)                                     Tenant will promptly pay to Landlord fifty percent (50%) of any consideration received for any assignment or fifty percent (50%) of the rent (fixed basic rent and additional rent) and any other consideration payable by the subtenant to Tenant under or in connection with a sublease, as and when received, in excess of the Fixed Basic Rent required to be paid by Tenant for the area sublet, which shall be adjusted to credit any reasonable, out-of-pocket, customary expenditures made by Tenant for purposes of obtaining the subtenant, including brokerage commissions and tenant improvement costs;

vi)                                  The acceptance by Landlord of any rent from the assignee or from any subtenant or the failure of Landlord to insist upon strict performance of any of the terms, conditions and covenants of this Lease will release neither Tenant, nor any assignee assuming this Lease, from the Tenant’s obligations set forth in this Lease;

vii)                               The proposed assignee or subtenant is not then an occupant of any part of the Building;

viii)                            The proposed assignee or subtenant is not an entity or a person or an affiliate of an entity with whom Landlord is or has been, within the preceding twelve (12) month period, negotiating to lease space in the Building or any other building owned by Landlord or its affiliates within a five-mile radius of the Building;

ix)                                    There will not be more than one (1) subtenant in the Premises;

x)                                       Tenant will not advertise the subtenancy for less than Landlord’s then current market rent for the Premises;

xi)                                    Tenant will pay Landlord a FIVE HUNDRED AND 00/100 DOLLAR ($500.00) administrative fee for each request for consent to any sublet or assignment simultaneously with Tenant’s request for consent to a specific sublet or assignment, provided that consent is not unreasonably denied; and

xii)                                 The proposed assignee or subtenant will use the Premises for the Permitted Use only.

c)                                      If Tenant is a corporation (other than a corporation whose stock is listed and traded on a nationally recognized stock exchange), the transfer (however accomplished, whether in a single transaction or in a series of related or unrelated transactions) of a majority of the issued and outstanding stock [or any other mechanism such as, by way of example, the issuance of additional stock, a stock voting agreement or change in class(es) of stock which results in a change of control of Tenant], and if Tenant is a partnership, joint venture or limited liability company (collectively “Entity”), the transfer (by one or more transfers) of an interest in the distributions of profits and losses of such Entity (or other mechanism, such as, by way of example, the creation of additional partnership or limited liability company interests) which results in a change of control of such Entity will be deemed an assignment of this Lease, subject to provisions of this Article.

2

Notwithstanding anything contained in this Lease to the contrary, Tenant may assign this Lease or sublet all or any portion of the Premises to (i) any corporation or other Entity directly or indirectly controlling or controlled by Tenant or under common control with Tenant, or (ii) any successor by merger, consolidation, corporate reorganization or acquisition of all or substantially all of the assets of Tenant even if Tenant is not the surviving entity (any transaction referred to in clauses (i) or (ii) hereof will be a “Permitted Transfer”) provided that the net worth of any transferee of a Permitted Transfer will not be less than the greater of (A) the net worth of Tenant immediately preceding the Permitted Transfer or (B) the net worth of Tenant as of the date of the execution and delivery of this Lease by both parties.  Any other assignment or subleasing of Tenant’s interest under this Lease will be subject to Landlord’s approval, which approval will not be unreasonably withheld, conditioned or delayed.

d)                                     Except as specifically set forth above, if any portion of the Premises or of Tenant’s interest in this Lease is acquired by any other person or entity, whether by assignment, mortgage, sublease, transfer, operation of law or act of the Tenant, or if Tenant pledges its interest in this Lease or in any security deposit required hereunder, Tenant will be in default.

7.                                      COMPLIANCE WITH RULES AND REGULATIONS:

Tenant will observe and comply with the rules and regulations set forth in Exhibit B and with such further reasonable rules and regulations as Landlord may prescribe from time to time.

8.                                      DAMAGES TO BUILDING:

If the Building is damaged by fire or any other cause to such extent that the cost of restoration, as reasonably estimated by Landlord, will equal or exceed twenty-five (25%) percent of the replacement value of the Building (exclusive of foundations) just prior to the occurrence of the damage, then Landlord may, no later than the sixtieth (60th) day following the damage, give Tenant a notice electing to terminate this Lease.  In such event, this Lease will terminate on the thirtieth (30th) day after the giving of such notice, and Tenant will surrender possession of the Premises on or before such date.  If this Lease is not terminated pursuant to this Article, Landlord will restore the Building and the Premises with reasonable promptness, subject to Force Majeure, as defined in Article 30 e)  below, and subject to the availability and adequacy of the insurance proceeds.  Landlord shall not be obligated to restore fixtures and improvements owned by Tenant.

In any case in which use of the Premises is affected by any damage to the Building, there will be either an abatement or an equitable reduction in Fixed Basic Rent, depending on the period for which and the extent to which the Premises are not reasonably usable for general office use. The words “restoration” and “restore” as used in this Article will include repairs.

9.                                      EMINENT DOMAIN:

If Tenant’s use of the Premises is materially affected due to the taking by eminent domain of (a) the Premises or any part thereof; or (b) any other part of the Building; then, in either event, this Lease will terminate on the date when title vests pursuant to such taking.  The Fixed Basic Rent, and any Additional Rent, will be apportioned as of such termination date and any Fixed Basic Rent or Additional Rent paid for any period beyond said date, will be repaid to Tenant.  Tenant will not be entitled to any part of the award for such taking or any payment in lieu thereof, but Tenant may file a separate claim for any taking of fixtures and improvements owned by Tenant which have not become the Landlord’s property, and for moving expenses, provided the same will, in no way, affect or diminish Landlord’s award.  In the event of a partial taking which does not effect a termination of this Lease but does deprive Tenant of the use of a portion of the Premises, there will be either an abatement or an equitable reduction in Fixed Basic Rent, depending on the period for which and the extent to which the Premises are not reasonably usable for general office use.

10.                               LANDLORD’S REMEDIES ON DEFAULT:

If Tenant defaults in the payment of Fixed Basic Rent or any Additional Rent or in the performance of any of the other covenants and conditions of this Lease or permits the Premises to become deserted, abandoned or vacated, Landlord shall give Tenant notice of such default, and if Tenant does not cure any Fixed Basic Rent or Additional Rent default within five (5) days or other default within thirty (30) days after the giving of such notice (or if such other default is of such nature that it cannot be completely cured within such period, if Tenant does not commence such curing within such thirty (30) days and thereafter proceed with reasonable diligence and in good faith to cure such default), then Landlord may terminate this Lease or Tenant’s right to possession upon not less than ten (10) additional days notice to Tenant, and on the date specified in such notice Tenant’s right to possession of the Premises will cease, but Tenant will remain liable as provided below in this Lease.  If this Lease or Tenant’s right to possession will have been so terminated by Landlord, Landlord may at any time thereafter recover possession of the Premises by any lawful means and remove Tenant or other occupants and their effects.  Landlord may, at Tenant’s expense, relet all or any part of the Premises and may make such alterations, decorations or other changes to the Premises as Landlord considers appropriate in connection with such reletting, without relieving Tenant of any liability under this Lease. Tenant shall pay to Landlord, on demand, such expenses as Landlord may incur, including, without limitation, court costs and reasonable attorney’s fees and disbursements, in enforcing the performance of any obligation of Tenant under this Lease.

Tenant hereby waives all right of redemption to which Tenant or any person under Tenant might be entitled by any Legal Requirement.

11.                               DEFICIENCY:

In any case where Tenant has defaulted and Landlord has recovered possession of the Premises or terminated this Lease or Tenant’s right to possession, Tenant’s obligation to pay Landlord all the Fixed Basic Rent and Additional Rent up to and including the Expiration Date will not be discharged or otherwise affected.  Landlord will have all rights and remedies available to Landlord at law and in equity by reason of Tenant’s default, and may periodically sue to collect the accrued obligations of the Tenant together with interest at Prime plus four percent per annum from the date owed to the date paid, but in no event greater than the maximum rate of interest permitted by law.

Alternatively, in any case where Landlord has recovered possession of the Premises by reason of Tenant’s default, Landlord may at Landlord’s option, and at any time thereafter, and without notice or other action by Landlord, and without prejudice to any other rights or remedies it might have hereunder or at law or equity, become entitled to recover from Tenant, as damages for such breach, in addition to such other sums herein agreed to be paid by Tenant, to the date of re-entry, expiration and/or dispossess, an amount equal to the difference between the Fixed Basic Rent and Additional Rent reserved in this Lease from the date of such default to the date of Expiration Date of the original Term and the then fair and reasonable rental value of the Premises for the same period. Said damages shall become due and payable to Landlord immediately upon such breach of this Lease and without regard to whether this Lease be terminated or not, and if this Lease be terminated, without regard to the manner in which it is terminated. In the computation of such damages, the difference between an installment of Fixed Basic Rent and Additional Rent thereafter becoming due and the fair and reasonable rental value of the Premises for the period for which such installment was payable shall be discounted to the date of such default at the rate of not more than six percent (6%) per annum.

12.                               SUBORDINATION:

This Lease will, at the option of any holder of any underlying lease or holder of any first mortgage or first trust deed, be subject and subordinate to any such underlying lease and to any first mortgage or first trust deed which may now or hereafter affect the Real Property, and also to all renewals, modifications, consolidations and replacements of such underlying leases and first mortgage or first trust deed provided, that Lessor shall use commercially reasonable efforts to obtain a non-disturbance agreement from the holder of any such underlying lease, mortgage or trust deed. Any expenses charged by the mortgagee in connection with the obtaining of the aforesaid agreement shall be paid by Tenant.  Although no instrument or act on the part of Tenant will be necessary to effectuate such subordination, Tenant will, nevertheless, within ten (10) days prior written request by Landlord, execute and deliver such further instruments confirming such subordination of this Lease as may be desired by the holders of such first mortgage or first trust deed or by any of the lessors under such underlying leases.  If any underlying lease to which this Lease is subject terminates, Tenant will, on timely request, recognize and acknowledge the owner of the Real Property as Tenant’s landlord under this Lease.

Landlord represents that there currently is no mortgage encumbering the Building.

13.                               SECURITY DEPOSIT:

Tenant will deposit with Landlord on the signing of this Lease by Tenant, the Security Deposit for the performance of Tenant’s obligations under this Lease, including the surrender of possession of the Premises to Landlord in the condition required under this Lease.  If Landlord applies all or any part of the Security Deposit to cure any default of Tenant, Tenant will, on demand, deposit with Landlord the amount so applied so that Landlord will have the full Security Deposit on hand at all times during the Term.  In the event of a bona fide sale of the Real Property, subject to this Lease, Landlord will transfer the Security Deposit to the purchaser, and Landlord will be considered released by Tenant from all liability for the return of the Security Deposit; and Tenant agrees to look solely to the new landlord for the return of the Security Deposit, and it is agreed that this will apply to every transfer or assignment made of the Security Deposit to a new landlord.  Provided Tenant is not in default, the Security Deposit (less any portions of it previously used, applied or retained by Landlord), will be returned to Tenant after the expiration or sooner termination of this Lease and delivery of the entire Premises to Landlord in accordance with the provisions of this Lease.  Tenant will not assign, pledge or otherwise encumber the Security Deposit, and Landlord will not be bound by any such assignment, pledge or encumbrance.

14.                               RIGHT TO CURE TENANT’S BREACH:

If Tenant breaches any covenant or condition of this Lease, Landlord may, on prior notice to Tenant (except that no notice need be given in case of emergency), cure such breach at the expense of Tenant, and the reasonable amount of all expenses, including attorney’s fees, incurred by Landlord in so doing (whether paid by Landlord or not) will be deemed payable on demand as Additional Rent.

15.                               LIENS:

Tenant will not permit any lien or other encumbrance to be filed as a result of any act or omission (or alleged act or omission) of Tenant. Tenant will, within ten (10) days after notice from Landlord, discharge or satisfy by bonding or otherwise any liens filed against Landlord or all or any portion of the Real Property as a result of any such act or omission, including any lien or encumbrance arising from contract or tort claims.

16.                               RIGHT TO INSPECT AND REPAIR:

Landlord or its designees may enter the Premises (but will not be obligated to do so) at any reasonable time on reasonable notice to Tenant (except that no notice need be given in case of emergency) for the purpose of: (i) inspection; (ii) performance of any work or the making of such repairs, replacements or additions in, to, on and about the Premises or the Building, as Landlord deems necessary or desirable; or (iii) showing the Premises to prospective purchasers, mortgages and tenants.  Tenant will provide Landlord or its designees free and unfettered access to any mechanical or utility rooms, conduits, risers or the like located within the Premises.  Landlord or any prospective tenant shall have the right, upon at least twenty-four (24) hours written notice, to enter the space to perform inspections, surveys, measurements or such other reasonable activities as may be necessary to prepare the Premises for occupancy by the succeeding tenant so long as such actions do not materially interfere with the conduct of Tenant’s business. Tenant will have no claims, including claims for interruption of Tenant’s business, or cause of action against Landlord by reason of entry for such purposes.

4

17.                               SERVICES TO BE PROVIDED BY LANDLORD:

a)                                      Landlord will furnish to the Premises (i) electricity for normal lighting and ordinary office machines, (ii) during Building Hours, HVAC required for the reasonable use and occupancy of the Premises, and (iii) janitorial service (as set forth in Exhibit D), all in a manner comparable to that of similar buildings in the area. In addition, Landlord shall provide Common Facilities lighting at the Real Property during Building Hours and for such additional hours as, in Landlord’s judgment, is necessary or desirable to insure proper operation of the Real Property.

b)                                     Tenant will be entitled to make use of HVAC beyond the Building Hours, at Tenant’s sole cost and expense.  Tenant will pay Landlord the HVAC After Hours Charge (as defined in the Basic Lease Provisions) for HVAC beyond the Building Hours.

18.                               TENANT’S ESTOPPEL:

Tenant will, from time to time, on not less than ten (10) business days prior written request by Landlord, execute, acknowledge and deliver to Landlord an estoppel certificate containing such information as Landlord may reasonably request.

19.                               HOLDOVER TENANCY:

Tenant agrees that it must surrender possession of the Premises to Landlord on the Expiration Date or earlier termination of the Term.  Tenant agrees to indemnify and hold Landlord harmless from and against all liabilities, obligations, damages, penalties, claims, costs, charges and expenses, including attorneys’ fees, resulting from any delay by Tenant in so surrendering the Premises, including any claims made by any succeeding tenant based on such delay. Tenant agrees that if possession of the Premises is not surrendered to Landlord on the Expiration Date or earlier termination of the Term, then Tenant agrees to pay Landlord as liquidated damages for each month and for any portion of a month during which Tenant holds over in the Premises after the Expiration Date or earlier termination of the Term, a sum equal to 200% of the average Fixed Basic Rent and Additional Rent which was payable per month under this Lease during the last three months of the Term.  Such liquidated damages shall not limit Tenant’s indemnification obligation with respect to claims made by any succeeding tenant based on Tenant’s failure or refusal to surrender the Premises to Landlord on the Expiration Date or sooner termination of the Term.  Nothing contained herein shall be deemed to authorize Tenant to remain in occupancy of the Premises after the Expiration Date or sooner termination of the Term.

20.                               LANDLORD’S WORK; COMMENCEMENT:

a) Landlord agrees that, prior to the Commencement Date, Landlord will perform and complete work in the Premises in accordance with Exhibit C of this Lease so as to provide a turnkey fit-out of the Premises (the “Work”).

b) In addition to the requirements of Exhibit C with respect to “substantial completion”, a satisfactory inspection of the Work by the applicable governmental authority allowing the Premises to be legally occupied for the Permitted Use and allowing Tenant to commence business operations, which may be later evidenced by a (temporary or final) Certificate of Occupancy (although the date of issuance may be other than the Commencement Date), will constitute sufficient evidence to demonstrate that Landlord has performed the Work and the Term has commenced, subject to the Punch List.

c) Notwithstanding anything contained in this Lease to the contrary, if Tenant (or anyone having rights under or through Tenant) shall occupy all or any part of the Premises and commence business operations prior to the date Landlord has completed the Work, then the Commencement Date shall be deemed to occur on such date that Tenant (or anyone claiming under or through Tenant) shall occupy all or any part of the Premises for the purpose of commencing business operations.

d) Notwithstanding anything contained in this Lease to the contrary, if Landlord, for any reason whatsoever cannot deliver possession of the Premises to Tenant on the Commencement Date set forth in the Basic Lease Provisions, this Lease will not be void or voidable, nor will Landlord be liable to Tenant for any loss or damage resulting therefrom, but in that event, the Term will commence on the earlier of: (i) the date Landlord delivers possession of the Premises to Tenant or (ii) the date Landlord would have delivered possession of the Premises to Tenant but for any reason attributable to Tenant.

e)  Notwithstanding anything contained herein to the contrary, provided that Tenant shall execute and deliver this Lease to Landlord on or before December 11, 2009, if Landlord has not delivered possession of the Premises to Tenant on or before May 1, 2010, due to reasons other than Force Majeure or Tenant’s own acts or omissions, Landlord shall, as Tenant’s sole remedy, reimburse Tenant for: (i) all “holdover” costs actually incurred by Tenant pursuant to of its current lease with 450 Sentry Parkway Associates dated January 21, 2005  (hereinafter “Current Lease”), accruing from May 1, 2010 through and including the day immediately preceding the Commencement Date hereof (the “Holdover Period”), to the extent such holdover rent for the Holdover Period exceeds the base monthly rent reserved in the Current Lease for the last month of the term thereof; provided, however, that Landlord’s obligation hereunder shall not exceed $939.22 per day for the Holdover Period.  Provided that (i) the Lease is in full force and effect, (ii) Tenant is not in default hereunder, (iii) Tenant takes occupancy of the Premises and (iv) Tenant delivers to Landlord documentation reasonably satisfactory to Landlord evidencing Tenant’s actual payment of such holdover costs, Landlord shall reimburse such costs promptly upon presentation of evidence of payment of such fees by Tenant. Landlord shall have no obligation to reimburse Tenant for any holdover rental accruing as a result of Force Majeure or Tenant’s own acts or omissions. Tenant shall use reasonable efforts to minimize any holdover rent payable by Tenant under the Current Lease.

21.                               OVERDUE RENT CHARGE/INTEREST:

a) Tenant will pay an “Overdue Rent Charge” of eight percent (8%) of any installment of Fixed Basic Rent or Additional Rent which Tenant fails to pay within ten (10) days after the due date thereof, to cover the extra expense involved in handling non-payments and/or delinquent payments.  The Overdue Rent Charge will constitute Additional Rent and an agreed upon amount of liquidated damages and not a penalty.

b) Any amount owed by Tenant to Landlord which is not paid when due will bear interest at the lesser of (i) the rate of two percent (2%) per month from the due date of such amount, or (ii) maximum legal interest rate permitted by law. The payment of interest on such amounts will not extend the due date of any amount owed.

c) Notwithstanding anything in this Article to the contrary, Landlord shall waive a Late Charge one time during each Lease Year provided, however, the installment of Fixed Basic Rent or Additional Rent so due is paid by the fifteenth (15th) day of the month.  However, any payment received subsequent to the fifteenth (15th) of the month during these grace periods shall require a Late Charge to be reassessed and added to Tenant’s obligations hereunder.

22.                               INSURANCE:

a)                                      Tenant’s Insurance.  On or before the Commencement Date or Tenant’s prior entry into the Premises, Tenant will obtain and have in full force and effect, insurance coverage as follows:

(i)                                     workers’ compensation in an amount required by law; (ii) commercial general liability with a per occurrence limit of One Million Dollars ($1,000,000) and a general aggregate of Three Million Dollars ($3,000,000) for bodily injury and property damage on an occurrence basis and containing an endorsement naming Landlord, its agents, designees and lender as additional insureds, an aggregate limit per location endorsement (if any), and no modification that would make Tenant’s policy excess or contributing with Landlord’s liability insurance; (iii) all risk property insurance for the full replacement value of all of Tenant’s furniture, fixtures, equipment, alterations, improvements or additions that do not become Landlord’s property upon installation; and (iv) any other form or forms of insurance or any increase in the limits of any of the coverages described above or other forms of insurance as Landlord or the mortgagees or ground lessors (if any) of Landlord may reasonably require from time to time if in the reasonable opinion of Landlord or said mortgagees or ground lessors said coverage and/or limits become inadequate or less than that commonly maintained by prudent tenants with similar uses in similar buildings in the area.  All policies obtained by Tenant will be issued by carriers having ratings in Best’s Insurance Guide (“Best”) of A and VIII, or better (or equivalent rating by a comparable rating agency if Best no longer exists) and licensed in the State.  All such policies must be endorsed to be primary and noncontributing with the policies of Landlord being excess, secondary and noncontributing.  No policy will be canceled, nonrenewed or materially modified without thirty (30) days’ prior written notice by the insurance carrier to Landlord.  If the forms of policies, endorsements, certificates, or evidence of insurance required by this Article are superseded or discontinued, Landlord may require other equivalent or better forms.  Evidence of the insurance coverage required to be maintained by Tenant, represented by certificates of insurance issued by the insurance carrier, must be furnished to Landlord prior to Tenant occupying the Premises and at least thirty (30) days prior to the expiration of current policies.  Copies of all endorsements required by this Article must accompany the certificates delivered to Landlord.  The certificates will state the amounts of all deductibles and self-insured retentions and that Landlord will be notified in writing thirty (30) days prior to cancellation, material change, or non-renewal of insurance.  If requested in writing by Landlord, Tenant will provide to Landlord a certified copy of any or all insurance policies or endorsements required by this Article.

b)                                     Tenant will not do or allow anything to be done on the Premises which will increase the rate of fire insurance on the Building from that of a general office building.  If any use of the Premises by Tenant results in an increase in the fire insurance rate(s) for the Building, Tenant will pay Landlord, as Additional Rent, any resulting increase in premiums.  Tenant’s insurance obligations set forth in Section 22 a) (i) and (ii) above shall continue in effect throughout the Term and after the Term as long as Tenant, or anyone claiming by, through or under Tenant, occupies all or any part of the Premises.

c)                                      Waiver of Claims. Landlord and Tenant hereby waive all claims and release each other and each other’s employees, agents, customers and invitees from any and all liability for any loss, damage or injury to property occurring in, on, about or to the Premises or the Building by reason of fire or other casualty, regardless of cause, including the negligence of Landlord or Tenant and their respective employees, agents, customers and invitees, and agree that the property insurance carried by either of them will contain a clause whereby the insurer waives its right of subrogation against the other party.  Each party to this Lease will give to its insurance company notice of the provisions of this Section 22 c) and have such insurance policies properly endorsed, if necessary, to prevent the invalidation of such insurance by reason of the provisions of this Section c).  Each party shall bear the risk of its own deductibles.  Landlord and Tenant acknowledge that the insurance requirements of this Lease reflect their mutual recognition and agreement that each party will look to its own insurance and that each can best insure against loss to its property and business no matter what the cause.  If Tenant fails to maintain insurance or self insures for loss including, without limitation, business interruption, Tenant shall be deemed to have released Landlord for all loss or damage which would have been covered if Tenant had so insured.

d)                                     Building Insurance. Landlord will at all times during the Term carry a policy of insurance which insures the Building, including the Premises and the Work, if any, against loss or damage by fire or other casualty (namely, the perils against which insurance is afforded by a standard fire insurance policy); provided, however, that Landlord will not be responsible for, and will not be obligated to insure against, any loss of or damage to any personal property or trade fixtures of Tenant or any alterations which Tenant may make to the Premises or any loss suffered by Tenant due to business interruption.  All insurance maintained by Landlord pursuant to this Article may be effected by blanket insurance policies.

23.                               INDEMNITY:

Tenant will defend, indemnify and hold Landlord and its agents harmless from and against any and all claims, actions or proceedings, costs, expenses and liabilities, including attorneys fees and disbursements incurred in connection with each such claim, action or proceeding, whether in contract or tort, arising from Tenant’s use and occupancy of the Premises, including Tenant’s negligent acts or omissions at the Real Property.  In case any action or proceeding be brought against Landlord by reason of any such claim, Tenant, upon notice from Landlord, will, at Tenant’s expense, resist and defend such action or proceeding with counsel acceptable to Landlord.

24.                               BROKER:

Tenant represents and warrants to the Landlord that no broker brought about this transaction, except Tenant’s Broker and Tenant agrees to indemnify and hold Landlord harmless from any and all claims of any broker(s) (other than Tenant’s Broker) arising out of or in connection with the negotiations of or entering into of this Lease by Tenant and Landlord. Landlord shall pay a leasing commission to Tenant’s Broker per the terms of a commission agreement to be entered into between Landlord and Tenant’s Broker.

25.                               PERSONAL LIABILITY:

There will be no personal liability on the part of Landlord, its constituent members (including officers, directors, partners, members and trustees) and their respective successors and assigns or any mortgagee in possession, with respect to any of the terms, covenants and conditions of this Lease, and Tenant will look solely to the equity of Landlord in the Building for the satisfaction of each and every remedy of Tenant in the event of any breach by Landlord of any of the terms of this Lease to be performed by Landlord, such exculpation of liability to be absolute and without any exceptions whatsoever.

26.                               NOTICES:

Any notice by either party to the other shall be in writing and shall be deemed to have been duly given only if (i) delivered personally or (ii) sent by registered mail or certified mail return receipt requested in a postage paid envelope or (iii) sent by nationally recognized overnight delivery service, if to Tenant, at the Building; if to Landlord, at Landlord’s address as set forth above to the attention of President and Chief Executive Officer, with a copy to the attention of the Executive Vice President and General Counsel; or, to either at such other address as Tenant or Landlord, respectively, may designate in writing.  Notice shall be deemed to have been duly given, if delivered personally, on delivery thereof, if mailed, upon the third (3rd) day after the mailing thereof or if sent by overnight delivery service, the next business day.

27.                               AUTHORITY:

The signatories on behalf of Tenant represent and warrant that they are authorized to execute this Lease, and if Tenant is a corporation or other Entity, Tenant will, within fifteen (15) days of Landlord’s request, provide Landlord with a resolution confirming the authorization. Tenant represents and warrants to Landlord (i) that neither Tenant nor any person or entity that directly owns a ten percent (10%) or greater equity interest in Tenant nor any of its officers, directors or managing members (collectively, “Tenant and Others in Interest”) is a person or entity with whom U.S. persons or entities are restricted from doing business under regulations of the Office of Foreign Asset Control (“OFAC”) of the Department of the Treasury (including those named on OFAC’s Specially Designated and Blocked Persons List) or under any statute, executive order (including Executive Order 13224 signed on September 24, 2001 (the “Executive Order”) and entitled “Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism”), or other governmental action, (ii) that Tenant and Others in Interest’s activities do not violate the International Money Laundering Abatement and Financial Anti-Terrorism Act of 2001 or the regulations or orders promulgated thereunder (as amended from time to time, the “Money Laundering Act”), and (iii) that throughout the Term Tenant will comply with the Executive Order and the Money Laundering Act.

28.                               PARKING SPACES

Tenant’s occupancy of the Premises will include the use of the parking spaces set forth in the Basic Lease Provisions.  Tenant will, upon request, promptly furnish to Landlord the license numbers of the cars operated by Tenant and its subtenants, invitees, concessionaires, licensees and their respective officers, agents and employees.  If any vehicle of Tenant, or of any subtenant, invitee, licensee, concessionaire, or their respective officers, agents or employees, is parked in any part of the Real Property other than those portions of the parking area(s) designated for this purpose by Landlord, or if Tenant shall exceed the number of parking spaces allocated to Tenant in the Basic Lease Provisions, then, in addition to Landlord’s rights and remedies provided in this Lease, Tenant will pay to Landlord $100.00 per day.

29.                               RELOCATION:

Intentionally omitted.

30.                               MISCELLANEOUS:

a)                                                              If any of the provisions of this Lease, or the application of such provisions, will be invalid or unenforceable, the remainder of this Lease will not be affected, and this Lease will be valid and enforceable to the fullest extent permitted by law.

b)                                                             The submission of this Lease for examination does not constitute a reservation of, or option for, the Premises, and this Lease is submitted to Tenant for signature with the understanding that it will not bind Landlord unless and until it has been executed by Landlord and delivered to Tenant or Tenant’s attorney or agent and until the holder of any mortgage will have unconditionally approved this Lease, to the satisfaction of Landlord, if such approval is required under the terms of such mortgage.

c)                                                              No representations or promises will be binding on the parties to this Lease except those representations and promises expressly contained in the Lease.

7

d)                                                             The article headings in this Lease are intended for convenience only and will not be taken into consideration in any construction or interpretation of this Lease or any of its provisions.

e)                                                              Force Majeure means and includes those situations beyond either party’s reasonable control, including acts of God; strikes; inclement weather; or, where applicable, the passage of time while waiting for an adjustment of insurance proceeds, except that such passage of time shall not adversely effect Tenant’s right to an abatement of Fixed Basic Rent or Additional Rent as otherwise provided in the Lease.  Any time limits required to be met by either party hereunder, whether specifically made subject to Force Majeure or not, except those related to the surrender of the Premises by the end of the Term or payment of Fixed Basic Rent or Additional Rent, will, unless specifically stated to the contrary elsewhere in this Lease, be automatically extended by the number of days by which any required performance is delayed due to Force Majeure.

f)                                                                Tenant consents to the receipt of electronic messages from Landlord or its affiliates, but not for purposes of “Notice” under Paragraph 26 of the Lease.

g)                                                             No payment by Tenant or receipt by Landlord of a lesser amount than the Fixed Basic Rent and Additional Rent payable hereunder will be deemed to be other than a payment on account of the earliest stipulated Fixed Basic Rent and Additional Rent, nor will any endorsement or statement on any check or any letter accompanying any check or payment of Fixed Basic Rent or Additional Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Fixed Basic Rent and Additional Rent or to pursue any other remedy provided herein or by law.

h)                                                             No failure by either party to insist upon the strict performance of any covenant, agreement, term or condition of this Lease, or to exercise any right or remedy upon a breach of any such covenant, agreement, term or condition, and no acceptance by Landlord of full or partial rent during the continuance of any such breach by Tenant, will constitute a waiver of any such breach or of such covenant, agreement, term or condition unless otherwise agreed to by the parties in writing.  No consent or waiver, express or implied, by either party to or of any breach of any covenant, condition or duty of the other party will be construed as a consent or waiver to or of any other breach of the same or any other covenant, condition or duty, unless such consent or waiver is in writing and signed by the party granting such consent or waiver.

i)                                                                 Landlord covenants that if, and so long as, Tenant pays Fixed Basic Rent and any Additional Rent as required under this Lease, and performs Tenant’s other covenants under the Lease, Landlord will do nothing to affect Tenant’s right to peaceably and quietly have, hold and enjoy the Premises for the Term, subject to the provisions of this Lease.

j)                                                                 The provisions of this Lease will apply to, bind and inure to the benefit of Landlord and Tenant and their respective heirs, successors, legal representatives and assigns.  The term “Landlord” as used in this Lease means only the owner or a master lessee of the Building, so that in the event of any sale of the Building or of any master lease thereof, the Landlord named herein will be and hereby is entirely freed and relieved of all covenants and obligations of Landlord under this Lease accruing after such sale, and it will be deemed without further agreement that the purchaser or the new master lessee of the Building has assumed and agreed to carry out any and all covenants and obligations of Landlord accruing under this Lease after such sale.

k)                                                              Landlord reserves the right unilaterally to alter Tenant’s ingress and egress to the Building or make any change in operating conditions to restrict pedestrian, vehicular or delivery ingress and egress to a particular location, or at any time close temporarily any Common Facilities to make repairs or changes therein or to effect construction, repairs or changes within the Building, or to discourage non-tenant parking, and may do such other acts in and to the Common Facilities as in Landlord’s sole judgment may be desirable to improve their convenience. Notwithstanding the foregoing, Landlord shall exercise reasonable care to avoid any material interruption to Tenant’s business operations as a result of the exercise of such rights.

l)                                                                 To the extent such waiver is permitted by law, the parties waive trial by jury in any action or proceeding brought in connection with this Lease or the Premises.  This Lease will be governed by the laws of the State (without the application of any conflict of laws principles), and any action or proceeding in connection with this Lease shall be decided in the courts of the State.

m)                                                           Tenant agrees not to disclose the terms, covenants, conditions or other facts with respect to this Lease, including the Fixed Basic Rent and Additional Rent, to any person, corporation, partnership, association, newspaper, periodical or other entity, except to Tenant’s accountants or attorneys (who shall also be required to keep the terms of this Lease confidential) or as required by law.  This non-disclosure and confidentiality agreement will be binding upon Tenant without limitation as to time, and a breach of this paragraph will constitute a material breach under this Lease.  In addition, Tenants employees, contractors, etc. shall keep any of the terms and conditions of this Lease, including any billing statements and/or any backup supporting those statements, confidential.

n)                                                             Any State statutory provisions dealing with termination rights due to casualty, condemnation, delivery of possession or any other matter dealt with by this Lease are superseded by the terms of this Lease, but only to the extent such statutes permit waiver by agreement.

o)                                                             Whenever it is provided that Landlord will not unreasonably withhold, condition or delay consent or approval or will exercise its judgment reasonably (such consent or approval and such exercise of judgment being collectively referred to as “consent”), if Landlord delays, conditions or refuses such consent, Tenant waives any claim for money damages (including any claim for money damages by way of setoff, counterclaim or defense) based upon any claim or assertion that Landlord unreasonably withheld, conditioned or delayed consent.  Tenant’s sole remedy will be specific performance.  Failure on the part of Tenant to seek relief within 30 days after the date upon which Landlord has withheld, conditioned or delayed its consent will be deemed a waiver of any right to dispute the reasonableness of such withholding, conditioning or delaying of consent.

p)                                                             Notwithstanding anything to the contrary contained in this Lease, in no event will Landlord or Tenant be liable to the other for the payment of consequential, punitive or speculative damages, except as provided in Article 19 hereof.

31.                               LANDLORD’S SECURITY INTEREST:

As additional security for the faithful performance and observance by Tenant of all of the terms, provisions and conditions of this Lease, Tenant hereby grants to and creates on behalf of Landlord a security interest in all of Tenant’s equipment, fixtures, decorations, alterations, furniture, machinery, installations, additions and improvement in the Premises.  The security interest herein granted and any security interest of the Landlord granted by statute shall be subordinate, solely as to furniture, trade fixtures and other personalty, to any purchase money security interest given by Tenant in connection with the financing of the purchase of the item of personalty in question.  This Lease constitutes a security agreement under the Pennsylvania Uniform Commercial Code.  Tenant agrees from time to time to execute and deliver such security agreements and financing statements as Landlord shall reasonably require to evidence and/or perfect the lien of the security interest granted herein, within five (5) days of Landlord’s request therefor.  Upon the occurrence of any default hereunder by Tenant, beyond applicable notice and cure periods, Landlord may, at its option, foreclose on said security and apply the proceeds of the sale of the property covered thereby for the payment of all rent owing under this Lease or any other sum owing by Tenant under the terms of Article 10 above, including, but not limited to any damages or deficiencies resulting from any reletting of the Premises, whether said damage or deficiency accrued before or after summary proceedings or other re-entry by Landlord.  Tenant covenants that it shall keep and maintain all fixtures, machinery, equipment, furnishings and other personalty at the Premises, whether or not the property of Tenant, in good, substantial and efficient operating condition (including replacement of same when necessary) at Tenant’s sole cost and expense, at all times during the term of this Lease.

32.                               USE AND OCCUPANCY TAX AND MISCELLANEOUS TAXES:

Tenant shall pay prior to delinquency all taxes (or its equivalent) assessed against or levied or imposed upon its use and occupancy of the Premises or upon the fixtures, furnishings, equipment and all other personal property of Tenant located in the Premises and when possible Tenant shall cause said fixtures, furnishings, equipment and all other personal property to be assessed and billed separately from the property of Landlord.  In the event any or all of Tenant’s fixtures, furnishings, equipment and all other personal property or its occupancy of the Premises shall be assessed and taxed with the property of Landlord, Tenant shall pay to Landlord its share of such taxes within twenty (20) days after delivery to Tenant by Landlord of a statement in writing setting forth the amount of such taxes applicable to Tenant’s fixtures, furnishings, equipment, personal property or occupancy.  If, during the Term of this Lease or any renewal or extension thereof, any tax is imposed upon the privilege of renting or occupying the Premises or upon the amount of rentals collected therefor, Tenant will pay each month, as Additional Rent, a sum equal to such tax or charge that is imposed for such month, but nothing herein shall be taken to require Tenant to pay any income, estate, inheritance or franchise tax imposed upon Landlord except to the extent required by Exhibit G hereof.  In addition, Tenant will pay as additional rent, all school district business use and occupancy tax applicable to Tenant and the Premises (if any) within the time set forth in any bill rendered by the taxing authority having such authority, or Landlord for said tax.   Landlord shall have the same rights and remedies for the non-payment of such use and occupancy tax, or any other item hereunder, that it has upon Tenant’s failure to pay rent hereunder.

33.                               OPTION TO RENEW:

(a)                                  If the term of this Lease shall then be in full force and effect and Tenant has complied fully with its obligations hereunder, Tenant shall have the option to extend the term of this Lease for a period of three (3) years (the “Renewal Term”) commencing on the day immediately following the Expiration Date, provided however that Tenant shall give Landlord notice of its election to extend the term no earlier than twelve (12) months prior to the Expiration Date nor later than nine (9) months prior to the Expiration Date of the term.  TIME BEING OF THE ESSENCE in connection with the exercise of Tenant’s option pursuant to this Article.

(b)                                 Such extension of the term of this Lease shall be upon the same covenants and conditions, as herein set forth except for the Fixed Basic Rent (which shall be determined in the manner set forth below), and except that Tenant shall have no further right to extend the term of this Lease after the exercise of the single option described in paragraph (a) of this Section.  If Tenant shall duly give notice of its election to extend the term of this Lease, the Renewal Term shall be added to and become a part of the Term of this Lease (but shall not be considered a part of the initial Term), and any reference in this Lease to the “Term of this Lease”, the “Term hereof”, or any similar expression shall be deemed to include such Renewal Term, and, in addition, the term “Expiration Date” shall thereafter mean the last day of such Renewal Term.  Landlord shall have no obligation to perform any alteration or preparatory or other work in and to the Premises or provide a tenant improvement allowance and Tenant shall continue possession thereof in its “as is” condition.

(c)                                  If Tenant exercises its option for the Renewal Term, the Fixed Basic Rent during the Renewal Term shall be the fair market rent for the Premises, as hereinafter defined.

(d)                                 Landlord and Tenant shall use their best efforts, within thirty (30) days after Landlord receives Tenant’s notice of its election to extend the Term of this Lease for the Renewal Term (“Negotiation Period”), to agree upon the Fixed Basic Rent to be paid by Tenant during the Renewal Term.  If Landlord and Tenant shall agree upon the Fixed Basic Rent for the Renewal Term, the parties shall promptly execute an amendment to this Lease stating the Fixed Basic Rent for the Renewal Term.

(e)                                  If the parties are unable to agree on the Fixed Basic Rent for the Renewal Term during the Negotiation Period, then within fifteen (15) days after notice from the other party, given after expiration of the Negotiation Period, each party, at its cost and upon notice to the other party, shall appoint a person to act as an appraiser hereunder, to determine the fair market rent for the Premises for the Renewal Term.  Each such person shall be a real estate broker or appraiser with at least ten years’ active commercial real estate appraisal or brokerage experience (involving the leasing of office space as agent for both landlords and tenants) in the County of Montgomery.  If a party does not appoint a person to act as an appraiser within said fifteen (15) day period, the person appointed by the other party shall be the sole appraiser and shall determine the aforesaid fair market rent.  Each notice containing the name of a person to act as appraiser shall contain also the person’s address.  Before proceeding to establish the fair market rent, the appraisers shall subscribe and swear to an oath fairly and impartially to determine such rent.

9

If the two appraisers are appointed by the parties as stated in the immediately preceding paragraph, they shall meet promptly and attempt to determine the fair market rent.  If they are unable to agree within forty-five (45) days after the appointment of the second appraiser, they shall attempt to select a third person meeting the qualifications stated in the immediately preceding paragraph within fifteen (15) days after the last day the two appraisers are given to determine the fair market rent.  If they are unable to agree on the third person to act as appraiser within said fifteen (15) day period, the third person shall be appointed by the American Arbitration Association (the “Association”), upon the application of Landlord or Tenant to the office of the Association nearest the Building.  The person appointed to act as appraiser by the Association shall be required to meet the qualifications stated in the immediately preceding paragraph.  Each of the parties shall bear fifty percent (50%) of the cost of appointing the third person and of paying the third person’s fees.  The third person, however selected, shall be required to take an oath similar to that described above.

The three appraisers shall meet and determine the fair market rent.  A decision in which two of the three appraisers concur shall be binding and conclusive upon the parties.  In deciding the dispute, the appraisers shall act in accordance with the rules then in force of the Association, subject however, to such limitations as may be placed on them by the provisions of this Lease.

(f)                                    After the fair market rent for the Renewal Term has been determined by the appraiser or appraisers and the appraiser or appraisers shall have notified the parties, at the request of either party, both parties shall execute and deliver to each other an amendment of this Lease stating the Fixed Basic Rent for the Renewal Term.

(g)                                 If the Fixed Basic Rent for the Renewal Term has not been agreed to or established prior to the commencement of the Renewal Term, then Tenant shall pay to Landlord an annual rent (“Temporary Rent”) which Temporary Rent shall be equal to one hundred twenty-five percent (125%) of the Fixed Basic Rent payable by Tenant for the last year of the Term immediately preceding the Renewal Term.  Thereafter, if the parties shall agree upon a Fixed Basic Rent, or the Fixed Basic Rent shall be established upon the determination of the fair market rent by the appraiser or appraisers, at a rate at variance with the Temporary Rent (i) if such Fixed Basic Rent is greater than the Temporary Rent, Tenant shall promptly pay to Landlord the difference between the Fixed Basic Rent determined by agreement or the appraisal process and the Temporary Rent, or (ii) if such Fixed Basic Rent is less than the Temporary Rent, Landlord shall credit to Tenant’s subsequent monthly installments of Fixed Basic Rent the difference between the Temporary Rent and the Fixed Basic Rent determined by agreement or the appraisal process.

(h)                                 In describing the fair market rent during the Renewal Term, the appraiser or appraisers shall be required to take into account the rentals at which leases are then being concluded (as of the last day of the Term) (for leases with similar lease terms with the lessor and lessee each acting prudently, with knowledge and for self-interest, and assuming that neither is under undue duress) for comparable space in the Building and in comparable office buildings in the County of Montgomery.

(i)                                     The option granted to Tenant under this Article 33 may be exercised only by Tenant, its permitted successors and assigns, and not by any subtenant or any successor to the interest of Tenant by reason of any action under the Bankruptcy Code, or by any public officer, custodian, receiver, United States Trustee, trustee or liquidator of Tenant or substantially all of Tenant’s property.  Tenant shall have no right to exercise this option subsequent to the date Landlord shall have the right to give the notice of termination referred to in Article 10 of the Lease unless Tenant cures the default within the applicable grace period.  Notwithstanding the foregoing, Tenant shall have no right to extend the term if, at the time it gives notice of its election (i) Tenant shall not be in occupancy of substantially all of the Premises or (ii) the Premises (or any part thereof) shall be the subject of a sublease.  If Tenant shall have elected to extend the term, such election shall be (at Landlord’s sole option) deemed withdrawn if, at any time after the giving of notice of such election and prior to the commencement of the Renewal Term, Tenant shall sublease (all or any portion of) the Premises or assign Tenant’s interest in this Lease.

34.                               TERMINATION OPTION:

Notwithstanding anything to the contrary contained herein, Tenant shall have a one-time option to surrender the Premises (“Termination Option”) in accordance with the following terms and conditions:

a.                                       If Tenant desires to exercise the Termination Option, Tenant shall give Landlord irrevocable written notice (“Termination Notice”) of Tenant’s exercise of this Termination Option, which shall be delivered by certified mail which Termination Notice must be received by Landlord no later than the date that is nine (9) full months prior to the Termination Date.  TIME IS OF THE ESSENCE with respect to Landlord’s receipt of the Termination Notice and all other deadlines in this Article.

b.                                      If Tenant gives the Termination Notice and complies with all the provisions in this Article, the Lease as it applies to the Premises only shall terminate at 11:59 p.m. on the last day of the month during which the day prior to the forty-second (42nd) month anniversary of the Commencement Date occurs (the “Termination Date”).

c.                                       In consideration for Tenant’s termination of this Lease, Tenant shall pay Landlord $118,971.00 (“Termination Fee”) simultaneously with the Termination Notice sent by Tenant to Landlord.

d.                                      Tenant’s obligations to pay Fixed Basic Rent, Additional Rent, and any other costs or charges under this Lease, and to perform all other Lease obligations for the period up to and including the Termination Date, shall survive the termination of this Lease.

e.                                       Notwithstanding the foregoing, if at any time during the period on or after the date on which Tenant shall exercise its Termination Option, up to and including the Termination Date, Tenant shall be in default of this Lease, then Landlord may elect, but is not obligated, to cancel and declare null and void Tenant’s exercise of the Termination Option and this Lease shall continue in full force and effect for the full Term hereof unaffected by Tenant’s exercise of the Termination Option.  If Landlord does not cancel Tenant’s exercise of the Termination Option after Tenant’s default, Tenant shall cure any default within the period of time specified in this Lease and this obligation shall survive the Termination Date.

g.                                      If Tenant shall fail to deliver possession of the Premises on or before the Termination Date in accordance with the terms hereof, Tenant shall be deemed to be a holdover Tenant from and after the Termination Date, and in such event all covenants and terms of Article 19 shall apply and shall also be liable to Landlord for all costs and expenses incurred by Landlord in securing possession of the Premises.  Landlord may accept any such sums from Tenant without prejudice to Landlord’s right to evict Tenant from the Premises by any lawful means.

h.                                      If Tenant properly and timely exercises the Termination Option and properly and timely satisfies all other monetary and non-monetary obligations under this Lease, the Lease as it applies to the Premises shall cease and expire on the Termination Date with the same force and effect as if said Termination Date were the date originally provided in this Lease as the Expiration Date of the Term hereof.

i.                                          If this Lease has been assigned or all or a portion of the Premises has been sublet, this Termination Option shall be deemed null and void and neither Tenant nor any assignee or sublessee shall have the right to exercise such option during the term of such assignment or sublease.

EXHIBIT C

WORKLETTER AGREEMENT

INOVIO BIOMEDICAL CORPORATION (“Tenant”) and we (“Landlord”) are executing a written lease (“Lease”), covering premises located at 1787 Sentry Park West, Blue Bell, PA, as more particularly described in the Lease (“Premises”).

To induce Tenant to enter into the Lease (which is hereby incorporated by reference) and in consideration of the covenants contained in this Workletter Agreement (the “Workletter”), Landlord and Tenant agree as follows:

1.             Landlord, at its sole cost and expense, will have its architect prepare the following architectural and mechanical drawings and specifications based upon the sketch layout supplied to Landlord by Tenant.

a.             Architectural drawings and specifications for Tenant’s partition layout, reflected ceiling, placement of electrical outlets and other installations for the work to be done by Landlord.

b.             Mechanical plans and specifications where necessary for installation of air conditioning systems, ductwork and heating.

All such plans and specifications are expressly subject to Landlord’s written approval, which approval will not be unreasonably withheld.

2.             Landlord agrees to cause the partition plan, electrical plan and the reflected ceiling plan to be delivered to Tenant on or before the fifteenth (15th) day after Lease execution.  Tenant agrees to approve the plans by initialing and returning them to Landlord within three (3) days of receipt of each plan.  Upon approval of the plans initialed by Tenant, Landlord will file the plans with the appropriate governmental agencies. This Lease is expressly conditioned upon Landlord obtaining a building permit from the appropriate government official for the Work (as hereinafter defined).

3.             Landlord agrees, at its expense and without charge to Tenant (unless otherwise provided), to do the work in the Premises as shown on the approved plans described above and described on SK-3 dated October 1, 2009 and the “Description of Materials” schedule attached to this Workletter, which will be referred to as the “Work” in the following provisions of this Workletter.  “Building Standard” will mean the type and grade of material, equipment and/or device designated by Landlord as standard for the Building.  All items are Building Standard unless otherwise noted.

4.             Intentionally omitted.

5.             All low partitioning, workstation modules, bank screen partitions and prefabricated partition systems will be furnished and installed by Tenant at its expense.

6.             The installation or wiring of telephone and computer (data) outlets is not part of the Work. Tenant will bear the responsibility to provide its own telephone and data systems at Tenant’s sole cost and expense.

7.             Changes in the Work, if necessary or requested by the Tenant, will be accomplished after the execution of the Lease and  this Workletter, and without invalidating any part of the Lease or Workletter, by written agreement between Landlord and Tenant (referred to as a “Change Order”).  Each Change Order will be prepared by Landlord and signed by both Tenant  and Landlord stating their agreement on all of the following:

a.             The scope of the change in the Work; and

b.             The cost of the change; and

c.             The manner in which the cost will be paid; and

d.             The estimated extent of any adjustment to the Commencement Date (if any) as a result of the change in the Work.

Each and every Change Order will be signed by Landlord’s and Tenant’s respective construction representatives.  In no event will any Change Order(s) be permitted without such authorizations.  A 10% supervision plus 10% overhead charge will be added to the cost of any Change Order and to the cost of any other work to be performed by Landlord in the Premises due to changes requested by Tenant after Landlord’s completion of the Work.  If Tenant fails to approve any such Change Order within one (1) week, it will be deemed disapproved in all respects by Tenant, and Landlord will not be authorized to proceed on it.  Any increase in the cost of the Work or the change in the Work stated in a Change Order requested by Tenant which results from Tenant’s failure to timely approve and return said Change Order will be paid by Tenant.  Tenant agrees to pay Landlord the cost of any Change Order requested by Tenant upon receipt of an invoice for the Change Order.

8.             If Tenant elects to use the architect suggested by Landlord, this architect becomes solely the Tenant’s agent with respect to the plans, specifications and the Work.  If any change is made after completion of schematic drawings and prior to completion of final construction documents which result in a Change Order and additional costs, such costs will be the responsibility of the Tenant.

9.             Upon substantial completion of the Work which shall be determined by Landlord’s architect at Landlord’s expense and prior to Tenant’s occupancy of all or any part of the Premises, Tenant will identify and list any portion of the Work which does not conform to this Workletter or the Lease (“Punch List”).  The Landlord will review with the Tenant all of the items so listed and correct or complete any portion of the Work referenced in the Punch List which fails to conform to the requirements of this Workletter or the Lease.

10.           The terms contained in the Lease (which includes all Exhibits to the Lease) constitute Landlord’s agreement with Tenant with respect to the Work.

11.           Except as set forth in the last sentence of this paragraph or other provisions of the Lease, all Work within the Premises will become the property of Landlord upon installation, except for those items described in paragraph 5 above, including workstation modules.  No refund, credit or removal of any Work will be permitted at the expiration or earlier termination of the Lease.  Items installed that are not integrated in any way with the Work (e.g., furniture and other trade fixtures) become the property of Tenant upon installation.

1

12.           It is agreed that notwithstanding the date provided in the Basic Lease Provisions for the Commencement Date, the term will not commence until the earlier of (i) the date Tenant (or anyone claiming under or through Tenant) occupies all or any part of the Premises and commences business operations or (ii) the date Landlord has “substantially completed” the Work; provided, however, that if Landlord is delayed in substantially completing the Work as a result of:

a.             Tenant’s failure to approve the plans and specifications in accordance with Paragraph 2 of this Workletter;

b.             Tenant’s failure to furnish interior finish specifications (i.e., paint colors, carpet selection, etc.) to Landlord by  the fifth (5th) business day after Tenant has approved the plans and specifications pursuant to Paragraph 2;

c.             Tenant’s request for materials, finishes or installations other than Landlord’s Building Standard;

d.             Tenant’s changes in the Work;

e.             The performance of a person, firm, partnership or corporation employed by Tenant and the non-completion of work by such person, firm, partnership or corporation; and/or

f.              Any act or omission of Tenant which delays governmental inspections and approvals, including, if necessary and without limitation, failure to install furniture and/or failure to obtain low voltage wiring permits;

then the Commencement Date will be accelerated by the number of days of such delay, and Tenant’s obligation to pay Fixed Basic Rent and Additional Rent will commence as of such earlier date.

13.           Landlord will permit Tenant and its agents to enter, as licensees only, the Premises prior to the Commencement Date so that Tenant may perform through its own contractors such other work and decorations as Tenant may desire at the same time Landlord’s contractors are working in the Premises.  Such license shall not trigger an earlier Commencement Date. The foregoing license to enter prior to the Commencement Date, however, is conditioned upon:

a.             Tenant’s workmen and mechanics working in harmony and not interfering with the labor employed by Landlord, Landlord’s mechanics or contractors or by any other tenant or its mechanics or contractors;

b.             Tenant providing Landlord with evidence of Tenant’s contractors and subcontractors carrying such worker’s compensation insurance as required by law, commercial general liability and property insurance in amounts no less than the amounts set forth in Article 22 a) of the Lease.  If at any time such entry will cause disharmony or interference of the nature described in subparagraph 13 a) above, this license may be withdrawn by Landlord upon forty-eight (48) hours written notice to Tenant.  Such entry will be deemed controlled by all of the terms, covenants, provisions and conditions of the Lease, except as to the covenant to pay Fixed Basic Rent, Additional Rent and utilities.  Landlord will not be liable in any way for any injury, loss or damage which may occur to any of Tenant’s decorations or installations made prior to the Commencement Date, the same being solely at Tenant’s risk; and

c.             Tenant will use union contractors if required by Landlord so long as Landlord is also using union contractors.

14.           No part of the Premises will be deemed unavailable for occupancy by Tenant, nor will any work which the Landlord is obligated to perform in such part of the Premises be deemed incomplete for the purpose of any adjustment of Fixed Basic Rent payable under the Lease, if minor details of construction, decoration or mechanical adjustments exist and the non-completion of such details does not materially interfere with the Tenant’s use of such part of the Premises.

15.           If construction is to occur in a space occupied by Tenant’s employees, Tenant will be liable for all costs associated with a delay, if Tenant fails to comply with a submitted construction schedule to relocate personnel, furniture or equipment.  These costs will include, but not be limited to, the following:

a.             cost of construction workers time wasted;

b.             cost of any overtime work necessary to meet schedule deadlines; and

c.             any other costs associated with delays in final completion.

16.           This Workletter is based on the materials and layouts set forth or referenced in the Workletter.  Any change to the materials and layout will require a recalculation of construction costs and any increases in costs caused by changes made by Tenant shall be Tenant’s responsibility.  Such recalculation will not negate any other Article of this Lease.

17.           All sums payable by Tenant to Landlord in connection with this Exhibit C and any other work to be performed by Landlord within the Premises and billable to Tenant will be deemed Additional Rent.

18.           With respect to the construction work being conducted in or about the Premises, each party agrees to be bound by the approval and actions of their respective construction representatives.  Unless changed by written notification, the parties designate the following individuals as their respective construction representatives:

a.             Operating Cost Escalation — If the Operating Costs incurred for the  Real Property for any Lease Year or Partial Lease Year during the Term will be greater than the Base Operating Costs (reduced proportionately to correspond to the duration of periods less than a Lease Year), then Tenant will pay to Landlord, as Additional Rent, Tenant’s Percentage of all such excess Operating Costs.  Operating Costs will include, by way of illustration and not of limitation: personal property taxes; management fees for the Building only; labor, including all wages and salaries for those employees working at the Building (to the extent that employees work at the Building and other building(s) owned or managed by Landlord or an affiliate of Landlord, such wages and salaries shall be reasonably allocated by Landlord among such buildings); social security and other taxes which may be levied against Landlord upon such wages and salaries; supplies; repairs and maintenance; maintenance and service contracts; painting; wall and window washing; tools and equipment (which are not required to be capitalized for federal income tax purposes); trash removal; lawn care; snow removal and all other items properly constituting direct operating costs according to standard accounting practices (collectively referred to as the “Operating Costs” in this Lease); but not including depreciation of Building or equipment; interest; income or excess profits taxes; costs of maintaining the Landlord’s corporate existence; franchise taxes; any expenditures required to be capitalized for federal income tax purposes, unless said expenditures are for the purpose of reducing Operating Costs at the Real Property, or those which under generally applied real estate practice are expensed or regarded as deferred expenses or are required under any Legal Requirement, in which event the costs thereof shall be included.  Notwithstanding anything contained herein to the contrary, any additional costs incurred by Landlord during the Calendar Year by reason of Landlord or any of its vendors entering into new labor contracts or renewals or modifications of existing labor contracts will not be included in Base Operating Costs.  In addition, Tenant will pay Landlord Tenant’s Percentage of all costs and expenses incurred by Landlord in connection with complying with any “homeland security” requirements and such costs and expenses will not be included in Operating Costs.

If any repair, replacement or improvement within the definition of Operating Costs is capitalized under generally accepted accounting principles, then (A) the cost of any such repair, replacement or improvement shall only be included in Operating Costs if such repair, replacement or improvement (i) is necessary to comply with any governmental or quasi-governmental law, statute, ordinance, rule, order, requirements or regulation, which is enacted or promulgated after the date hereof, (ii) is reasonably intended to reduce Operating Costs or (iii) constitutes a replacement which in Lessor’s reasonable judgment is economically prudent to make in lieu of repairs, (B) the cost thereof shall be amortized on a straight line basis over the lesser of ten (10) years or the useful life of such repair, (C) the amount so amortized attributable to such repair, replacement or improvement shall be included in Operating Costs in each Lease Year for such portion of the amortization period which occurs during the Term, provided, however, that all amounts thereof included in Operating Costs in any Lease Year subsequent to the year paid shall have added thereto interest from the date Lessor incurred such cost.  For amortization purposes, applicable interest shall be two (2) percentage points in excess of the prime rate charged by JP Morgan Chase Bank, or its successor, at the time of expenditure.

b.             Intentionally omitted.

c.             Tax Escalation — If the Real Estate Taxes for the Real Property for any Lease Year or Partial Lease Year during the Lease Term will be greater than the Base Real Estate Taxes (reduced proportionately to correspond to the duration of periods less than a Lease Year), then Tenant will pay to Landlord as Additional Rent, Tenant’s Percentage of all such excess Real Estate Taxes.

As used in this Lease, “Real Estate Taxes” mean the property taxes and assessments imposed upon the Building and other portions of the Real Property, or upon the rent payable to the Landlord, including, but not limited to, real estate, city, county, village, school and transit taxes, or taxes, assessments, or charges levied, imposed or assessed against the  Real Property by any taxing authority, whether general or specific, ordinary or extraordinary, foreseen or unforeseen.  If due to a future change in the method of taxation, any franchise, income or profit tax will be levied against Landlord in substitution for, or in lieu of, or in addition to, any tax which would otherwise constitute a Real Estate Tax, such franchise, income or profit tax will be deemed to be a Real Estate Tax for purposes of this Lease.

Landlord, will have the exclusive right, but not the obligation, to contest or appeal any Real Estate Tax assessment levied on all or any part of the Real Property.

d.             Insurance Cost Escalation — If the Insurance Costs for the Real Property for any Lease Year or Partial Lease Year during the Term will be greater than the Base Insurance Costs (reduced proportionately to correspond to the duration of periods less than a Lease Year), Tenant will pay to Landlord as Additional Rent for each Lease Year or Partial Lease Year, Tenant’s Percentage of such excess Insurance Costs.

As used in this Lease, “Insurance Costs” mean all fire, general liability and other insurance costs, together with any deductibles, incurred by Landlord in connection with its operation and maintenance of the Real Property for any Lease Year or Partial Lease Year during the Term.

e.             Lease Year — As used in this Lease, Lease Year will mean a calendar year. Any portion of the Term which is less than a Lease Year, that is, from the Commencement Date through the following December 31, and from the last January 1 falling within the Term to the end of the Term, will be deemed a “Partial Lease Year”.  Any reference in this Lease to a Lease Year will, unless the context clearly indicates otherwise, be deemed to be a reference to a Partial Lease Year if the period in question involves a Partial Lease Year.

f.              Payment — Prior to each Lease Year, Landlord will give Tenant an estimate of amounts payable under this Rider for such Lease Year or Partial Lease Year. By the first day of each month during such Lease Year or Partial Lease Year, Tenant will pay Landlord one-twelfth (1/12th) of the estimated amount.  If, however, the estimate is not given before such Lease Year or Partial Lease Year begins, Tenant will continue to pay by the first day of each month on the basis of last year’s estimate, if any, until the month after the new estimate is given.  As soon as practicable after each Lease Year or Partial Lease Year ends, Landlord will give Tenant a statement (the “Statement”) showing the actual amounts payable by Tenant under this Rider for such Lease Year.  If the Statement shows that the actual amount Tenant owes for such Lease Year or Partial Lease Year is less than the estimated amount paid by Tenant during such Lease Year or Partial Lease Year, Landlord, at its option, will either return the difference or credit the difference against the next succeeding payment(s) of Additional Rent.  If the Statement shows that the actual amount Tenant owes is more than the estimated Additional Rent paid by Tenant during such Lease Year or Partial Lease Year, Tenant will pay the difference within thirty (30) days after the Statement is delivered to Tenant.

g.             Books and Reports — Landlord will maintain books of account which, provided that Tenant has not breached this Lease, will be open to Tenant and its representatives at all reasonable times so that Tenant can determine that such Operating, Insurance and Real Estate Tax Costs have, in fact, been paid or incurred. Tenant’s representatives will mean only (i) Tenant’s employees or (ii) a Certified Public Accounting firm, and neither Tenant’s employees nor any Certified Public Accounting firm will be permitted to perform such inspection and/or audit on a contingency basis or for any other tenant in the Building.  At Landlord’s request, Tenant and/or Tenant’s Certified Public Accounting firm will execute a confidentiality agreement reasonably acceptable to Landlord prior to any examination of Landlord’s books and records.  In the event Tenant disputes any one or more of such charges, Tenant will attempt to resolve such dispute with Landlord, provided that if such dispute is not satisfactorily settled between Landlord and Tenant within thirty (30) days, then upon request of either party, the dispute will be referred to an independent certified public accountant to be mutually agreed upon to arbitrate the dispute, and if such an accountant cannot be agreed upon, the American Arbitration Association may be asked by either party to select an arbitrator, whose decision on the dispute will be final and binding upon both parties, who will jointly share any cost of such arbitration. Pending resolution of the dispute, the Tenant will pay to Landlord the sum so billed by Landlord, subject to its ultimate resolution as set forth above or Landlord will either return the difference or credit the difference against next succeeding payment(s) of Additional Rent.  The arbitration mechanism set forth above shall be the sole process available to resolve such disputes.

h.             Right of Review — Once Landlord will have finally determined the Operating, Insurance or Real Estate Tax Costs at the expiration of a Lease Year, then as to the item so established, Tenant will only be entitled to dispute such charge for a period of six (6) months after such charge is billed to Tenant, and Tenant specifically waives any right to dispute any such charge any time after the expiration of said six (6) month period.

i.              Occupancy Adjustment — If the Building is less than ninety-five percent (95%) occupied during the Calendar Year or during any Lease Year or Partial Lease Year subsequent to the Calendar Year, then the Operating Costs will be adjusted during the Calendar Year and the Operating Costs will be adjusted during any such Lease Year or Partial Lease Year so as to reflect ninety-five percent (95%) occupancy. The aforesaid adjustment will only be made with respect to those items that are in fact affected by variations in occupancy levels.

j.              The parties agree that Tenant’s Percentage, as defined in the Basic Lease Provisions, reflects and will be continually adjusted to reflect the ratio of the gross square feet of the area rented to Tenant (including an allocable share of all Common Facilities) [the numerator] as compared with the total number of gross square feet of the entire Building (or additional buildings that may be constructed within the Real Property) [the denominator] measured outside wall to outside wall, but excluding therefrom any storage areas.  Landlord shall have the right to make changes or revisions in the Common Facilities of the Building so as to provide additional leasing area. Landlord shall also have the right to construct additional buildings in the Real Property for such purposes as Landlord may deem appropriate, and subdivide the lands for that purpose if necessary, and upon so doing, the Real Property shall become the subdivided lot on which the Building in which the Premises is located. Notwithstanding the foregoing, Tenant’s Percentage shall not increase during the Term, unless the rentable area of the Premises shall increase. However, if any service provided for in subparagraph a. or any utility provided for in subparagraph b. is separately billed or separately metered within the Building, then the square footage so billed or metered shall be subtracted from the denominator and the Tenant’s proportionate share for such service and/or utility shall be separately computed, and the Base Period Costs for such item shall not include any charges attributable to said square footage.  Tenant understands that as a result of changes in the layout of the Common Facilities from time to time occurring due to, by way of example and not by way of limitation, the rearrangement of corridors, the aggregate of all Building tenant proportionate shares may be equal to, less than or greater than one hundred percent (100%).

EXHIBIT H

ELECTRICITY RIDER

Landlord shall cause electricity to be supplied to the Premises (“Building Standard Office Electrical Service”).  Tenant shall obtain and pay for Tenant’s separate supply of electric current by direct application to, and arrangement with, the utility companies servicing the Building.  Landlord or the applicable utility company shall provide such meters used to measure such electricity service at Landlord’s expense.  Tenant shall pay all charges with respect to consumption of electricity applicable to the Premises directly to the utility company servicing the Building.  Any and all rebates, grants and subsidies for utilities issued by the utility companies servicing the Building or other public or quasi-public institutions shall remain the property of Landlord. Tenant shall promptly pay Landlord any rebates, grants and subsidies Tenant receives in connection with utility services received by Tenant in the Building, unless Tenant has incurred the expense necessary that gave rise to such rebates, grants and subsidies. If, pursuant to a legal requirement or the policies or operating practices of the utility company servicing the Building, Tenant is no longer permitted to obtain electrical energy directly from the utility company, Landlord will furnish electrical energy to the Premises either, at Landlord’s option, on a “check-metering” basis or a rent inclusion basis.  Landlord shall give Tenant notice at least thirty (30) days prior to the date on which Landlord shall commence furnishing electrical energy to the Premises (unless such notice is not feasible under the circumstances, in which event Landlord will give Tenant such notice as is reasonably possible), which notice will set forth the terms on which Landlord will so furnish electrical energy to the Premises.  If any utilities are not (or cannot be) separately metered or assessed or are only partially separately metered or assessed and are used in common with other Tenants of the Building, Tenant will pay to Landlord an equitable apportionment of such charges for utilities used in common with other Tenants of the Building, based on the square footage of floor space leased to each Tenant using such common facilities, the average electrical consumption of each Tenant and other pertinent considerations, in addition to Tenant’s payment of the separately metered charges. Tenant shall defend, indemnify and hold Landlord harmless from and reimburse Landlord for all liability, damages, costs, fees, expenses, penalties and charges (including, but not limited to, attorneys’ fees and disbursements) incurred in connection with (i) Tenant’s failure to pay for any electricity provided to Tenant hereunder or (ii) misuse or neglect by Tenant of the meters(s) and equipment supplying the electricity.

d.             Tenant’s use of electric current in the Premises shall not exceed the capacity of any electrical conductors and equipment in or otherwise serving the Premises.

e.             Tenant shall not, without the prior consent of Landlord make or perform or permit any alteration to wiring installations or other electrical facilities for the supply of electric current located in or serving the Premises.  If Landlord grants such consent, all additional conduit, feeders and wiring and other equipment required therefor shall be provided and/or installed by Landlord and the reasonable cost thereof shall be paid by Tenant as Additional Rent within fifteen (15) days after demand therefor.

c.             Landlord shall not be liable in any way to Tenant for any loss, damage or expense which Tenant may sustain or incur as a result of any failure, defect or change in the quantity or character of electrical energy available for redistribution to the Premises pursuant to this Exhibit nor for any interruption in the supply, and Tenant agrees that such supply may be interrupted for inspection, repairs and replacement and in emergencies with at least forty-eight (48) hours advance notice (except for emergencies). Notwithstanding the foregoing and in any event, the full measure of Landlord’s liability for any interruption in the supply due to Landlord’s acts or omissions shall be an abatement of Fixed Basic Rent and Additional Rent, unless Landlord fails to take such measures as may be reasonable under the circumstances to restore such service without undue delay.  In no event shall Landlord be liable for any business interruption suffered by Tenant.

d.             Landlord, at Tenant’s expense, shall furnish and install all replacement lighting tubes, lamps, ballasts and bulbs required in the Premises.  Tenant, however, shall have the right to furnish and/or install any or all of the items mentioned in this sub-paragraph (d).

e.             Tenant shall pay, as Additional Rent, Tenant’s Percentage of the cost to the Building (including applicable sales or use taxes) for utility and energy costs, including any fuel surcharges or adjustments with respect thereto, incurred for water, sewer, gas and other utilities and heating, ventilating and air conditioning for the Building, to include all leased and leasable areas (not separately billed or metered within the Building) and Common Facilities electric and lighting, for the Building and Real Property, for any Lease Year or Partial Lease Year, during the Term (collectively, “Additional Utility Rent”).  Tenant shall pay to Landlord, on account of the Additional Utility Rent payable pursuant to this subparagraph e., the annual sum of $1.20 per square foot of gross rentable area of the Premises (“Estimated Additional Utility Rent”), subject to the adjustments on the first day of each and every calendar month of the term (except that if the first day of the term is other than the first day of a calendar month, the first monthly installment, prorated to the end of said calendar month, shall be payable on the first day of the first full calendar month).  From time to time during the term, the Estimated Additional Utility Rent may be adjusted by Landlord on the basis of either Landlord’s reasonable estimate of the Building’s and Real Property electric consumption and demand or the Building’s and Real Property actual consumption of and demand for electricity, and, in either event, the Electric Rate or Cost per Kilowatt and Cost per Kilowatt Hour then in effect.  Subsequent to the end of each calendar year during the Term, or more frequently if Landlord shall elect, Landlord shall submit to Tenant a statement of the Additional Utility Rent for such year or shorter period together with the components thereof, as set forth in this subparagraph e. (“Additional Utility Statement”).  To the extent that the Estimated Additional Utility Rent paid by Tenant for the period covered by the Additional Utility Statement shall be less than the Additional Utility Rent as set forth on such Additional Utility Statement, Tenant shall pay Landlord the difference within 30 days after receipt of the Additional Utility Statement.  If the Estimated Additional Utility Rent paid by Tenant for the period covered by the Additional Utility Statement shall be greater than the Additional Utility Rent as set forth on the Additional Utility Statement, such difference shall be credited against the next required payment(s) of Estimated Additional Utility Rent.  If no Estimated Additional Utility Rent payment(s) shall thereafter be due, Landlord shall pay such difference to Tenant. The utility and energy costs that vary with occupancy and that are attributable to any part of the Term in which less than ninety-five percent (95%) of the Building is occupied by tenants will be adjusted by Landlord to the amount that Landlord reasonably believes they would have been if ninety-five percent (95%) of the Building had been occupied.
