Lessor shall use its best efforts to perform such work, except in case of emergency, at times reasonably convenient to Lessee and otherwise in such manner and to the extent practical as will not unreasonably interfere with Lessee’s use and occupancy of the Demised Premises.

(b) The rent payable by Lessee shall be abated or reduced proportionately during any period in which, by reason of such damage, there is substantial interference with the operation of the business of Lessee. Such abatement or reduction shall continue for the period commencing with the damage and ending with the completion by Lessor of such repair and/or reconstruction.

11. CONDEMNATION

If the whole of the Demised Premises is taken or condemned under the exercise of the power of eminent domain by any public body or if the same is acquired from negotiations in lieu thereof, then Lessor, at its option, may terminate this Lease without liability to Lessee for damages of any kind or nature and Lessee hereby waives any interest it may have in the amount received from the public body.

12. UTILITIES AND TAXES

(a) In addition to Basic Rent, Lessee shall pay all charges for water, electricity, fuel and other utilities consumed at the Demised Premises during the Term. Lessee shall also pay demand or standby charges which may be charged by such utilities. With respect to Lessee’s

actual consumption of fuel and water at the Demised Premises, Lessor, at the end of the first lease year, shall reimburse Lessee for it’s actual costs of fuel and water consumption at the Demised Premises as invoiced by the utility companies up to a maximum amount of $16,500. For each lease year thereafter, Lessor shall reimburse Lessee up to a maximum amount of $16,500 (“Escalation Base”) as escalated annually by the Consumer Price Index for Lessee’s actual consumption of fuel and water at the Demised Premises. For purposes of this paragraph, the Consumer Price Index shall be for all items for the United States and the Escalation Base shall be $16,500. Beginning with the 24th month of the Lease, for purposes of calculating Lessor’s reimbursement escalation to Lessee, the index as of the 13th month of the initial term of the Lease shall constitute the Base Index. Beginning with the 24th month of the Lease, the Index as of the last month of each lease year shall constitute the Escalation Index. The Escalation Index shall be divided by the Base Index; this shall constitute the percentage increase of Lessor’s annual reimbursement escalation beginning with the 24th month. For example, if the Base Index on the 13th month is 120 and the Escalation Index on the 24th month is 150: Lessor’s escalation reimbursement to Lessee at the end of the second lease year would be (150/120)=125% X $16,500=$20,625. This calculation would be applicable to each lease year thereafter through April 30, 2008 only. Lessee shall submit those applicable invoices from the utility company to Lessor prior to Lessor’s reimbursement of fuel and water charges as herein provided.

(b) Lessee shall pay Lessor, throughout the Term, “Real Property Taxes” (as herein defined) above the Base Year Real Property Taxes as herein defined. Said payment to Lessor shall be made at the time such “Real Property Taxes” are due on a monthly basis in advance or if required by mortgagee or Lessor, the total amount due to the taxing authority upon receipt of bills by the taxing authority. The “Base Year” Real Property Taxes shall be $163,322.12. Beginning on May 1, 2008, the Base Year Real Property Taxes shall be equal to the total Real Property Taxes due for the Complex during the 2007/2008 fiscal tax year. For each succeeding lease year, in addition to Lessee’s Basic Rent, Lessee shall be responsible for any and all escalations of Real Property Taxes above the Base Year Real Property Taxes. “Real Property Taxes” shall mean all real estate and ad valorem taxes, assessments, water and sewer charges, school taxes and other governmental impositions and charges which shall be levied, assessed, imposed, or have become due and payable, or liens upon, or arising from the use, occupancy or possession of the Complex or any part thereof or any payments made in lieu thereof if the Complex is owned by an Industrial Development Agency created by the State of Connecticut. The term Real Property Taxes shall not include (i) any charge, such as a water meter charge and the sewer rent based thereon, which is measured by consumption or (ii) any municipal, state or federal taxes based on net income or any estate, inheritance or transfer taxes or any franchise taxes assessed against or imposed upon Lessor, except to the extent substituted for the then Real Property Taxes. Whether or not Lessor shall take the benefit of the provisions of any statute permitting any assessment for public betterments to be paid over a period of years, Lessor shall, nevertheless, be deemed to have taken such benefit so that the term Real Property Taxes shall include only the current annual installment of any such assessment. Lessor hereby covenants with Lessee that Lessor shall be responsible for paying and shall pay the Real Property Taxes and shall present receipted tax bills to Lessee.

(c) Lessee shall have the right of Lessor to protest the amount of any assessments but shall continue to pay the Real Property Taxes. Lessor agrees to cooperate with Lessee in such appeal.

(d) Lessee at all times shall be responsible for and shall pay, before delinquency, all taxes levied or assessed by any governmental authority on any leasehold interest, any investment of Lessee in the Demised Premises, or any personal property of any kind owned, installed or used by Lessee or on Lessee’s right to occupy the Demised Premises. In addition, Lessee shall be responsible for all taxes attributable to any increased assessment incurred as a result of any of Lessee’s Work (as defined in Article 4 hereof). In the event that Real Property Taxes are not separately assessed or attributable to such additions, the informal decision by the Tax Assessor with respect thereto shall be binding on the parties.

In connection with Lessee’s obligation set forth in this Article 13, Lessee shall obtain such insurance from an insurance company or companies of recognized responsibility with a Best’s Rating of A-VII or better and Lessee shall furnish Lessor with a Certificate of Insurance indicating the coverage and limits of liability applicable thereto and evidencing the inclusion of Lessor as an additional named insured under such policy, “As their interests may appear”. Lessor reserves the right to request certified copies of the policy and all its endorsements.

The “Certificate of Insurance” described above shall contain a thirty (30) day cancellation clause clearly shown therein. In addition said Certificate of Insurance shall clearly state that Lessor will be notified in the event of any reduction in coverage or any material change to the policy.

All policies of insurance (except liability insurance) shall provide by endorsement that any loss shall be payable to Lessor, Lessee, or any mortgagee as their respective interests may appear.

Lessee’s policy(s) shall be written as a primary policy not contributing with, or in excess of, insurance that Lessor or others in interest may have.

Lessee shall be responsible for any increased premiums due to Lessee’s use which will adversely impact any insurance policies covering the building.

It is recommended that Lessee carry all risk property insurance on all of Lessee’s property including contents, trade fixtures, and tenant improvements whether installed by Lessor or Lessee as these items are not insured under Article 13.I.(a).

In the event any policy recited to this Article 13 shall contain a deductible provision, said deductible, if incurred, shall be charged to the Complex as a Complex Operating Cost with respect to the coverages enumerated in Article 13.I. or shall be the responsibility of Lessee with regard to Article 13.II.

To the extent permitted by the insurance companies furnishing any of the above coverage there shall be a mutual waiver by Lessor and Lessee of subrogation so that with respect to any loss which is covered or required by this lease to be covered by insurance carried by Lessor or Lessee each releases the other from any and all claims with respect to any losses occurring thereunder.

14. SUBORDINATION

(a) Lessee agrees that this Lease shall be subordinate to any mortgage, deed of trust or any other hypothecation for security which has been or may be placed on the Demised Premises or any part thereof, and to any and all advances made or to be made thereunder, and to all renewals, replacements and extensions thereof, requested and made by Lessor and such subordination is hereby made effective without any further act to be done by Lessee; provided, however that Lessee’s obligation to subordinate this Lease as aforesaid is expressly conditioned upon receipt by Lessee of Mortgagee’s standard non-disturbance agreement from such mortgagee or other holder of a monetary lien upon the Demised Premises or any part thereof. Provided, however, in the event any documents including subordination agreements, lease ratification agreements and other necessary documents are required to be signed by Lessee to effectuate the purposes of this Article or the financing or refinancing of the Demised Premises, Lessee does hereby agree to execute all such documents upon written demand by Lessor, and to furnish such financial information as may be required. Lessee shall also sign a Subordination Non-Disturbance Agreement which shall be provided by Lessor and Lessor agrees to obtain for the benefit of the Lessee an executed non-disturbance agreement from each existing holder of a mortgagee or monetary lien upon the Demised Premises or any part thereof.

15. CONDITIONAL LIMITATION AND DEFAULT PROVISIONS

Subject to any contrary provisions of any applicable law, the following shall be conditional limitations of this Lease and events of default:

(a) Lessee’s failure to pay Rent, Real Property Taxes or other costs due and payable hereunder, which failure is not cured within ten (10) days after written notice of such failure from Lessor to Lessee.

(b) The nonperformance or violation of the terms and conditions of any other obligations required hereunder by Lessee, which nonperformance or violation is not cured within thirty (30) days after written notice thereof from Lessor to Lessee. If such nonperformance or violation cannot be cured within said 30-day period; the same will not be a default if Lessee exercises due diligence, in the sole discretion of Lessor, to cure such nonperformance or violation as promptly as possible.

(d) Lessee’s filing of voluntary bankruptcy proceedings or the making of an assignment for the benefit of creditors, or the filing of an involuntary bankruptcy proceeding, which involuntary proceeding is not terminated and dismissed within sixty (60) days after such filing.

In the event of such uncured defaults, Lessor may:

(a) Terminate this Lease and render it null and void and the Term of this Lease shall expire and all right, title and interest of Lessee shall expire and terminate as fully and completely as if the default day were the date the Term of this Lease expired, and Lessee will then immediately quit and surrender the Demised Premises to Lessor.

(b) Reenter the Demised Premises and receive rent therefrom.

(d) As liquidated damages, accelerate the balance of the rental payments due under the terms of this Lease.

Lessee shall remain liable for the rent and other charges as provided for herein. Lessee shall also be liable for any repairs or reasonable alterations necessary to prepare the Demised Premises for re-letting. Lessee waives any rights to damages against Lessor by reason of any negligent acts taken by Lessor under provisions of this Article after such default.

16. TERMINATION

Upon the expiration of the Term of this Lease, or any earlier termination thereof, Lessee shall surrender the Demised Premises to Lessor in a clean, wholesome and sanitary condition and in good condition and repair, reasonable wear and tear and insured casualties excepted. All structural alterations and improvements which have been made or installed by Lessee and any and all built-in or replacement fixtures, including all non portable refrigerated air conditioning equipment, all heating equipment, all electrical fixtures and units together with all conduits and wiring in connection with all of said fixtures, originally installed by Lessee or replaced by Lessee during the Term of this Lease, in or upon or about the Demised Premises, shall be the property of Lessor and shall be surrendered to Lessor without any payment therefor; or, in the alternative, at Lessor’s request, Lessee shall, prior to termination, remove any fixture, machinery or signs that Lessor may designate and otherwise restore the premises to its original condition, reasonable wear and tear and damage by the elements or other casualty excepted. Notwithstanding the foregoing, Lessor agrees that Lessee shall not be required to restore the third floor training room at the expiration of this Lease.

Twelve (12) months prior to expiration of the Term of this Lease, Lessor shall have the right to enter the Demised Premises for the purpose of showing same to prospective tenants or purchasers.

17. HOLDING OVER

In the event Lessee shall hold the Demised Premises after the expiration of the Term hereof, with or without the consent of Lessor, such holding over shall be deemed to have created a tenancy from month to month, terminable on thirty (30) days notice by either party to the other and subject to all the terms, conditions, covenants and agreements of this Lease, except that rental shall be two times the basic rent.

18. COMMISSIONS

Lessor shall pay any commissions payable with regard to this Lease and any provision hereunder pursuant to a separate agreement. Lessee represents that no broker other than O,R & L Commercial Real Estate, having an office at ▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ participated in the negotiations of the Lease, and Lessee represents that no other broker was a procuring cause with regard to this Lease and, accordingly, Lessee agrees to indemnify and hold Lessor harmless from the claim of any other broker with regard to this Lease.

19. INSPECTION OF PREMISES

Lessor or its representatives shall be entitled at any reasonable time and reasonable manner (excepting emergencies) to enter upon the Demised Premises for the purpose of inspecting the same, subject to Lessee’s reasonable security regulations.

20. FINANCIAL STATEMENTS

Lessee hereby agrees not to handle, store or dispose of any hazardous or toxic waste or substance upon the premises which is prohibited by applicable federal, state or local statues, ordinances or regulations. Lessee hereby covenants to indemnify and hold Lessor, its successors and assigns, harmless from any loss, damage, claims, costs, liabilities or clean-up costs arising out of Lessee’s use, handling, storage, or disposal of any such hazardous or toxic wastes or

substances as those terms are defined in any applicable statue, regulation or ordinance on the premises. Lessee agrees to indemnify Lessor for any and all expenses incurred in connection with, and all liabilities resulting from, any violation of any applicable environmental law, regulation, ordinance or court order pertaining to the Demised Premises arising other than from an action or omission by Lessor. As of the Commencement Date of this Lease, Lessor warrants that, without any investigation and to the best of its knowledge that the Complex is in compliance with all local, state and federal environmental regulations.

22. WAIVER OF TRIAL BY JURY

It is mutually agreed between Lessor and Lessee that the respective parties hereto shall and do hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties against the other on any matters whatsoever arising out of or in any way connected with this Lease, including rents or additional rents, Lessee’s use or occupancy of the Demised Premises, and/or any claim of injury or damage.

23. RECOVERY OF COSTS

In the event that any action or proceeding shall be brought for the purpose of determining or enforcing the rights of either party hereunder, the party prevailing in such actions or proceedings shall be entitled to recover from the other party all costs reasonably incurred by the prevailing party in connection with such action or proceeding including reasonable attorney’s fees to be determined by the Court.

26. LESSOR

Lessee shall be confined to and look solely to the estate and interest of Lessor, its successors and assigns, in the Complex and any insurance thereon or the proceeds therefrom, for the collection of any sum due to Lessee for any reason, and no other property or assets of Lessor shall be subject to levy, execution or other enforcement procedure for the satisfaction of Lessee’s remedies under or with respect to either this Lease, the relationship of Lessor and Lessee hereunder or Lessee’s use and occupancy of the Demised Premises.

6. not use or occupy the Demised Premises so as to require alterations or additions to be made thereto or to the Complex as a result of any law, code, rule, regulation, order, requirement or directive of any governmental authority having jurisdiction, or any code, rule, regulation, order, requirement, directive or recommendation of the local board of fire underwriters or of the fire insurance rating organization having jurisdiction, or any other body or agency as hereinabove described;

28. SHORING

If an excavation or other substructure work shall be undertaken or authorized upon land adjacent to the Demised Premises, Lessee, without liability on the part of Lessor therefor, shall afford to the person causing or authorized to cause such excavation or other substructure work license to enter upon the Demised Premises for the purpose of doing such work as such person shall deem necessary to protect or preserve any of the walls or structures of the building or surrounding lands from injury or damage and to support the same. Such entry shall be accomplished in the presence of a representative of Lessee. The said license to enter shall be afforded by Lessee without any diminution or abatement of rent on account thereof provided that such entry shall not unreasonably interfere with Lessee’s use of the Demised Premises.

29. LEASE MODIFICATION

In the event any lending institution funding the Demised Premises or the Complex for Lessor shall request reasonable modifications of this Lease as a condition of obtaining financing, Lessee will not unreasonably withhold, delay or defer its consent thereto, provided that such modifications do not adversely affect to a material degree Lessee’s leasehold interest hereby created or increase the Basic Rent or Lessee’s Share of Complex Operating Costs or change the Term of this Lease.

30. CONSTRUCTION OF LEASE

(a) The remedies available to Lessor under the terms of this Lease shall be cumulative and the exercise of one remedy shall not constitute an election of remedies.

(b) This Lease shall be constructed in accordance with the laws of the State of Connecticut.

(c) The term Lessor (as used herein) shall mean only the owner for the time of such ownership of Lessor’s interest in this Lease and such owner and each succeeding owner shall be liable hereunder to the extent as set forth in Article 26 hereof, only with respect to obligations arising during the period of its respective ownership in the Complex.

(d) Lessee agrees not to record this Lease, but upon request of Lessee, Lessor and Lessee shall execute and deliver to Lessee a notice of lease. Such notice shall identify the Demised Premises and include the term of the Lease and no other information concerning the monetary terms and conditions of this Lease.

(f) This Lease contains the entire agreement between the parties and no oral statements or representations or prior written matter not contained herein shall have any force or effect. This Lease shall not be modified in any way except by a writing executed by both parties.

31. ASSIGNMENT-SUBLETTING

Lessee shall not have the right to sublet or transfer less than 11,000 square feet of the Demised Premises (by assignment, or in any other manner (hereinafter referred to as sublet)) this Lease, or mortgage or otherwise encumber the leasehold interest of Lessee without first giving Lessor a written request for such transfer and without first obtaining in each and every instance the previous written consent of Lessor, which consent shall not be unreasonably withheld. Any assignment or hypothecation of the Demised Premises without the written consent of Lessor, shall be null and void. In no event shall Lessee be released from any liability hereunder.

In the event that Lessee desires to sublet the Demised Premises, in whole or in part, Lessee shall notify Lessor of its intention to do so. Lessee may solicit sublet proposals for the Demised Premises, in whole or in part (in no event less than 11,000 square feet), for Lessor’s approval. Upon submission to Lessor by Lessee of a Sublet Agreement for the Demised Premises, in whole or in part, (said Agreement being subject to Lessor’s written approval which consent shall not be unreasonably withheld, mortgagee’s written approval, and this underlying Lease) executed by and between the Sublessor (and assigns) and Sublessee, Lessor may at Lessor’s option, elect to terminate this Lease as of the effective date of the proposed transfer or sublet by giving Lessee written notice thereof within ten (10) days of Lessee’s submission of said Sublet Agreement to Lessor. In the event that Lessor so elects to terminate this Lease, the same will terminate and Lessee shall be released from liability hereunder for the balance of the Term of this Lease. In the event that Lessor does not notify Lessee within said ten (10) day period of Lessor’s intent to terminate this Lease, then Lessee may enter into such Sublet Agreement with subtenant. In no event shall Lessee be released from any liability hereunder.

Notwithstanding anything contained in this Article to the contrary,

(i) Subject to Lessor’s sole and absolute discretion and with Lessor’s prior written consent, Lessee shall be allowed to assign this Lease and to sublease the Demised Premises or any portion thereof whatsoever to any entity resulting from a merger or consolidation with Lessee or any entity succeeding to the business and assets of Lessee (herein after referred to collectively as “Merger”). Lessee shall give Lessor 30 days prior written notice of such Merger and Lessee shall supply to Lessor documentation evidencing such Merger.

(ii) Subject to Lessor’s sole and absolute discretion and with Lessor’s prior written consent, Lessee shall be allowed to assign this Lease and to sublease the Demised Premises or any portion there of whatsoever to an “Affiliate” of greater or equal financial standing. Such sublease or assignment shall not be subject to Lessor’s right of termination. The term “Affiliate” shall mean any entity that controls, is controlled by or is under the common control of the Lessee.

Nothing contained in this Article 31 shall be construed to release Lessee from any liabilities or responsibilities under the Lease.

In the event that Lessee sublets the Demised Premises at a rental rate exceeding Lessee’s then current Basic Rent, then Lessor, after Lessee is reimbursed for those actual costs it incurs subletting the Demised Premises, shall be entitled to all additional rent received by said Sublessee which exceeds Lessee’s Basic Rent.

32. ANTENNA/BACK-UP GENERATOR

Lessee may install, at its expense, a microwave, satellite or other antenna communication systems on the roof plus a back-up generator in a designated area on site. Lessee shall furnish plans and specifications for such system to Lessor for its approval, which shall not be unreasonably withheld or delayed.

33. LEASE CONTINGENCY

This Lease shall be contingent upon the receipt of an unconditional written approval by Lessor’s lender of all necessary documentation for the execution of this Lease, including a Lease guarantee agreement from Bayer Pharmaceutical Corporation.

Lessor shall not be liable to Lessee for any damages caused by any delay in the negotiation, execution or approval and delivery of this Lease.

LEASE OF IMPROVED PROPERTY

THIS AGREEMENT made as of this 19th day of February, 2010 by and between WU/LH 35 Executive L.L.C., a Delaware limited liability company, having an office at c/o Lighthouse Real Estate Management, ▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇▇▇ (“Lessor”) and Tangoe, Inc., a Delaware corporation, having an office and principal place of business at ▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ (“Lessee”).

WITNESSETH:

WHEREAS, Lessor, as successor-in-interest to ▇▇▇▇▇ Properties Limited Partnership, and Lessee, previously entered into a written Lease Agreement dated as of May 15, 2005, hereinafter referred to as the “Lease”, for general offices at ▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ (“Demised Premises”);

WHEREAS, the Lessee desires to extend the Term of the Lease, which is scheduled to expire on April 30, 2011, to and including April 30, 2016; and

WHEREAS, the Lessee and Lessor desire to modify the Lease in certain other respects as set forth herein.

NOW; THEREFORE, in consideration of the mutual covenants herein set forth and for other good and valuable consideration, the parties hereto agree to amend the Lease as of the date hereof as follows:

1. The Term of the Lease shall be extended for a period of five (5) years (the “Extension Period”), from May 1, 2011 (the “Extension Date”) to and including April 30, 2016. Accordingly, April 30, 2016 shall be deemed to be the “Expiration Date” under the Lease for all purposes thereof and of this Agreement.

2. (a) Lessee’s Basic Rent as defined in Article 3(a) of the Lease with respect to the Extension Period shall be as follows:

From	To	Annual Basic Rent		Monthly Basic Rent
5/1/11	4/30/12	$	1,221,000.00	$	101,750.00
5/1/12	4/30/13	$	1,221,000.00	$	101,750.00
5/1/13	4/30/14	$	1,246,080.00	$	103,840.00
5/1/14	4/30/15	$	1,271,160.00	$	105,930.00
5/1/15	4/30/16	$	1,297,560.00	$	108,130.00

(b) Lessee shall be entitled to an unconditional partial rent credit in the aggregate amount of Two Hundred Six Thousand Two Hundred Fifty and 00/100 ($206,250.00) Dollars, which shall be applied against Basic Rent in twelve (12) equal monthly installments of

Seventeen Thousand One Hundred Eighty-Seven and 50/100 ($17,187.50) Dollars each, during the first year of the Extension Period.

3. Lessee acknowledges that Lessor has made no representations to Lessee with respect to the condition of the Demised Premises and Lessee agrees to accept possession of the Demised Premises in the condition which shall exist on the Extension Date “as is” and further agrees that Lessor shall have no obligation to perform any work or make any installations in order to prepare the Demised Premises for Lessee’s continued occupancy except that, Lessor agrees, at Lessor’s expense, to perform the Lessor’s Work outlined in Exhibit A, attached hereto and made a part hereof, and Lessor warrants that the HVAC system installed, as part of the Lessor’s Work, to service the Demised Premises will be sufficient for the comfortable use and occupancy of the Demised Premises as currently populated. The term “comfortable occupancy” as used in the foregoing sentence shall mean: (i) in the summer, that on a 90 degree Fahrenheit (F.) Outside Air (OA) day with ninety (90%) percent humidity, inside average temperature will not exceed 78 degrees F. and (ii) in the winter, that on a 10 degree F. OA day, inside air average temperature will not fall below 68 degrees ▇. ▇▇▇▇▇▇ shall commence the performance of such Lessor’s Work reasonably promptly after the execution and unconditional delivery of this Agreement by Lessor and Lessee and shall thereafter reasonably diligently prosecute such work to completion, without any obligation on Lessor’s part to employ contractors or labor at so-called overtime or other premium pay rates. The performance of such work shall constitute a single non-recurring obligation on the part of Lessor and in the event the Lease is further renewed or extended for a further term by agreement or operation of law, Lessor’s obligation to perform such work shall not apply to any such renewal or extension. Lessor may enter the Demised Premises to perform such work, and entry by Lessor, its agents, servants, employees or contractors for such purpose shall not constitute an actual or constructive eviction, in whole or in part, or entitle Lessee to any abatement or diminution of rent or relieve Lessee from any of its obligations under the Lease or impose any liability upon Lessor or its agents by reason of inconvenience or annoyance to Lessee, or injury to or interruption of Lessee’s business or otherwise. The cost of the Lessor’s Work shall not be charged to Lessee as COC under Section 3(b) of the Lease.

4. Notwithstanding anything to the contrary contained in the Lease, effective as of May 1, 2011 (but without affecting any obligations of Lessee to and including April 30, 2011 under the existing provisions), the Base Year for COC shall be the calendar year 2011 and the Base Year Real Property Taxes shall be the Real Property Taxes in effect for the calendar year 2011.

5. The provisions of this Section 5 are effective as of May 1, 2011:

a. Except as set forth in b. of this Section 5, and subject to the provisions of Section 12(a) of the Lease, Lessee shall pay all charges for water, sewer, fuel and other utilities charged with respect to the Demised Premises during the Extension Period, including, without limitation, any demand or standby charges which may be charged by such utilities.

b. The following provision shall be deemed added to the Lease: Electricity: Except to the extent provided in Section 5.c. and 5.d. of this Agreement, Lessor shall pay all charges for electricity consumed on the Complex, as Lessee’s share of such charges has been included in the Basic Rent.

c. In the event the number of kilowatt hours of electric current (“kwh”) consumed by Lessee on the Demised Premises during an Electric Year (as defined hereinafter) exceeds the Annual Baseline Energy Consumption (determined as described in Subsection (1) of this Section 5.c.), Lessor may charge Lessee, as Electric Rent, the Average Cost Per KWH (determined as described in Subsection (2) of this Section 5.c.) for such Electric Year, multiplied by such number of kwh so in excess of the Animal Baseline Energy Consumption. Monthly, Lessor shall provide Lessee with the preceding month’s electric ▇▇▇▇, showing the number of kwh consumed by Lessee on the Demised Premises during such preceding month.

(1) The “Annual Baseline Energy Consumption” shall be the number of kwh shown by the meter readings for the Demised Premises to have been consumed by Lessee on the Demised Premises during the Twelve Month Baseline Period. The “Twelve Month Baseline Period” shall be the twelve (12) month period beginning on the date of substantial completion (herein, the “Date”) of the Lessor’s Work.

(2) The “Average Cost Per KWH” shall be determined for each twelve (12) month period (each such period, an “Electric Year”) beginning with the twelve (12) month period commencing on the first (1st) day of the thirteenth (13th) month next following the Date, by dividing the total amount charged by the utility company for total kwh consumed by Lessee in the Demised Premises during such twelve (12) month period, by the total number of kwh so consumed.

d. If, at any time or times during an Electric Year, the rates at which Lessor purchases electrical energy for the Demised Premises are increased to exceed the public utility rate schedule in effect as of October 22, 2009 (i.e., the date of the Source One Inc., Energy Audit Report), the Basic Rent for the remaining part of such Electric Year, and thereafter, shall, upon demand by Lessor, be increased in an amount which fairly and proportionately reflects the actual increase in the cost to Lessor of purchasing electrical energy for the Demised Premises as a result of such rate increase.

▇. ▇▇▇▇▇▇ represents that the electrical feeder or riser capacity serving the Demised Premises shall be adequate to serve the existing lighting fixtures and electrical receptacles presently installed in the Demised Premises as of the date of this Agreement and the electrical needs of the Lessor’s Work. Any additional feeders or risers to supply Lessee’s additional electrical requirements other than the Lessor’s Work, and all other equipment proper and necessary in connection with such feeders or risers, shall be installed by Lessor or, at Lessor’s election, by Lessee upon Lessee’s request, at the sole cost and expense of Lessee, provided that, in Lessor’s judgment, such additional feeders or risers are necessary and are permissible under applicable laws and insurance regulations and the installation of such feeders or risers will not cause permanent damage or injury to the Building or the Demised Premises or cause or create a dangerous or hazardous condition or entail excessive or unreasonable alterations or repairs or interfere with or disturb other Lessees or occupants of the Building.
