ARTICLE 6
TAX AND OPERATING EXPENSE PAYMENTS

6.01.Tenant shall pay, as Additional Rent, to Landlord, as hereinafter provided, Tenant’s share of the Real Estate Taxes. Tenant’s share of the Real Estate Taxes shall be the Real Estate Taxes for the Building and Land for the period in question, multiplied by the Tenant’s Fraction. The Real Estate Taxes for the Building and Land shall be calculated as if the full amount of such Real Estate Taxes is payable by tenants occupying 95% of the square footage of the Building. By way of illustration and not by way of limitation, if the Real Estate Taxes for the Building and Land amount to $100,000.00 and, further, if Tenant’s Real Estate Fraction is 7%, then Tenant’s proportionate share of Real Estate Taxes would be $7,368.42, i.e. $100,000.00 ÷ .95 x 7%. If any portion of the Building shall be exempt from all or any part of the Real Estate Taxes, then for the period of time when such exemption is in effect, the rentable space on such exempt portion shall be excluded when making the above computations in respect of the part of the Real Estate Taxes for which such portion shall be exempt. Landlord shall estimate the annual amount of Tenant’s proportionate share of the Real Estate Taxes (which estimate may be changed by Landlord at any time and from time to time), and Tenant shall pay to Landlord 1/12th of the amount so estimated on the first day of each month in advance. Tenant shall also pay to Landlord on demand from time to time the amount which, together with said monthly installments, will be sufficient in Landlord’s estimation to pay Tenant’s proportionate share of any Real Estate Taxes thirty (30) days prior to the date when such Real Estate Taxes shall first become due. When the amount of any item comprising Real Estate Taxes is finally determined for a real estate fiscal tax year, Landlord shall submit to Tenant a statement in reasonable detail of the same, and the figures used for computing Tenant’s proportionate share of the same, and if Tenant’s proportionate share so stated is more or less than the amount theretofore paid by Tenant for such item based on Landlord’s estimate, Tenant shall pay to Landlord the deficiency, or Landlord shall refund to Tenant the excess, within ten (10) Business Days after submission of such statement provided Tenant is not then in default of the Lease. Any Real Estate Taxes for a real estate fiscal tax year, a part of which is included within the Term and a part of which is not so included, shall be apportioned on the basis of the number of days in the real estate fiscal tax year included in the Term, and the real estate fiscal tax year for any improvement assessment will be deemed to be the one-year period commencing on the date when such assessment is due, except that if any improvement assessment is payable in installments, the real estate fiscal tax year for each installment will be deemed to be the one-year period commencing on the date when such installment is due.

6.02.Tenant shall pay, as Additional Rent, to Landlord, as hereinafter provided, Tenant’s share of the Operating Expenses. Tenant’s share of the Operating Expenses shall be the Operating Expenses for the period in question, multiplied by Tenant’s Fraction. Operating Expenses shall be calculated as if the full amount of such Operating Expenses is payable by

10

tenants occupying 95% of the square footage of the Building. By way of illustration and not by way of limitation, if the operating Expenses amount to $100,000.00 and further if Tenant’s operating Fraction is 7%, then Tenant’s proportionate share of Operating Expenses would be $7,368.42, i.e. $100,000.00 ÷ .95 x 7%. Landlord shall estimate Tenant’s annual proportionate share of the Operating Expenses (which estimate may be reasonably changed by Landlord from time to time), and Tenant shall pay to Landlord 1/12th of the amount so estimated on the first day of each month in advance. If at any time Landlord changes its estimate of Tenant’s proportionate share of the Operating Expenses for the then current Calendar Year or partial Calendar Year, Landlord shall give notice to Tenant of such change and within ten (10) Business Days after such notice Landlord and Tenant shall adjust for any overpayment or underpayment during the prior months of the then current Calendar Year or partial Calendar Year. After the end of each Calendar Year, including any partial Calendar Year at the beginning of the Term, and after the end of the Term, Landlord shall submit to Tenant a statement in reasonable detail stating Tenant’s proportionate share of the Operating Expenses for such Calendar Year, or partial Calendar Year in the event the Term shall begin on a date other than a January 1st and/or end on a date other than a December 31st, as the case may be, and stating the Operating Expenses for the period in question and the figures used for computing Tenant’s proportionate share, and if Tenant’s proportionate share so stated for such period is more or less than the amount paid for such period, Tenant shall pay to Landlord the deficiency, or Landlord shall refund to Tenant the excess, within ten (10) Business Days after submission of such statement of Tenant’s proportionate share provided Tenant is not then in default of the Lease.

6.03.Each such statement given by Landlord pursuant to Section 6.01 or Section 6.02 shall be conclusive and binding upon Tenant unless within one (1) year after the receipt of such statement Tenant shall notify Landlord that it disputes the correctness of the statement, specifying the particular respects in which the statement is claimed to be incorrect. If such dispute is not settled by agreement, either party may submit the dispute to arbitration as provided in Article 36. Pending the determination of such dispute by agreement or arbitration as aforesaid, Tenant shall, within ten (10) Business Days after receipt of such statement, pay the Additional Charges in accordance with Landlord’s statement, without prejudice to Tenant’s position. If the dispute shall be determined in Tenant’s favor, Landlord shall within ten (10) Business Days pay to Tenant the amount of Tenant’s overpayment resulting from compliance with Landlord’s statement.

ARTICLE 7

Landlord may do such other acts in and to the Common Areas as in its judgment may be desirable to improve or maintain same. In connection with the foregoing, Landlord shall make reasonable efforts to avoid a material adverse impact on the conduct of Tenant’s business and shall provide adequate ingress and egress to the Demised Premises.

Upon such attornment this Lease shall continue in full force and effect as a direct lease between the Successor Landlord and Tenant upon all of the terms, conditions and covenants as are set forth in this Lease except that the Successor Landlord shall not (a) be liable for any previous act or omission of Landlord under this Lease;

13

(b) be subject to any offset, not expressly provided for in this Lease, which theretofore shall have accrued to Tenant against Landlord; or (c) be bound by any previous modification of this Lease or by any previous prepayment of more than one month’s Fixed Rent or Additional Rent, unless such modification or prepayment shall have been expressly approved in writing by the Successor Landlord.

9.04.If any then present or prospective Superior Mortgagee shall require any modification(s) of this Lease, Tenant shall promptly execute and deliver to Landlord such instruments effecting such modification(s) as Landlord shall request, provided that such modification(s) do not adversely affect in any material respect any of Tenant’s rights under this Lease, for example, and not by way of limitation, changes to the Term, Fixed Rent, Additional Rent and location of the Demised Premises.

ARTICLE 10

10.01.So long as Tenant pays all of the Rent and performs all of Tenant’s other obligations hereunder, Tenant shall peaceably and quietly have, hold and enjoy the Demised Premises without hindrance, ejection or molestation by Landlord or any person lawfully claiming through or under Landlord, subject, nevertheless, to the provisions of this Lease and to Superior Leases and Mortgages.

(c)in the reasonable opinion of Landlord, be a tenant whose occupancy will be in keeping with the dignity and character of a commercial building, including, without limitation, telecommunications facilities, office, retail and other lawful uses and the use and occupancy of the Building and whose occupancy will not be more objectionable or more hazardous than that of Tenant herein or impose any additional burden upon Landlord in

14

the maintenance and operation of the Building and shall, in the reasonable opinion of the Landlord, be eligible, suitable and qualified as a tenant in the Building in accordance with the provisions of this Lease.

In connection with any proposed assignment, sublease or transfer, Tenant shall pay to the Landlord on demand the reasonable costs (including attorney’s fees and costs) that may be incurred by the Landlord, including, without limitation, the reasonable costs of making investigations as to the acceptability of the proposed assignee or sublessee.

11.03.An assignment of this Lease as to which Landlord’s consent shall be required shall be deemed to include: (i) if Tenant is a corporation not listed on a recognized security exchange, one or more sales or transfers of stock, by operation of law or otherwise, or creation of new stock, by which an aggregate of more than 50% of Tenant’s stock shall be vested in a party or parties who are non-stockholders as of the date hereof (except in the case of an Initial Public Offering issued through a nationally recognized securities exchange); and (ii) if Tenant is a sole owner, partnership, limited liability company or joint venture, the transfer of any interest in the Tenant, whether by sale, exchange, merger, consolidation or otherwise.

Subject to Section 11.02, Landlord shall grant its consent to assignments of this Lease pursuant to transactions with a corporation into which the Tenant may be merged or consolidated or to any corporation which shall be an affiliate, subsidiary, parent or successor of Tenant, or of a corporation into which or with which Tenant may be merged or consolidated, or to a partnership, the majority interest in which shall be owned by stockholders of Tenant.

For the purposes of this Article, a “subsidiary” or “affiliate” or “successor” of Tenant shall mean the following:

(a)an “affiliate” shall mean any corporation which, directly or indirectly, controls or is controlled by or is under common control with Tenant. For this purpose “control” shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such corporation, whether through the ownership of voting securities or by contract or otherwise;

11.04.If this Lease is assigned, whether or not in violation of this Lease, Landlord may collect Rent from the assignee. If the Demised Premises or any part thereof are sublet or used or occupied by anybody other than Tenant, whether or not in violation of this Lease, Landlord may, after default collect Rent from the subtenant or occupant. In either event, Landlord may apply the net amount collected to the Rent, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of any of the provisions of Section 11.01 or Section 11.02, or the acceptance of the assignee, subtenant or occupant as tenant, or a release of Tenant from the performance by Tenant of Tenant’s obligations under this Lease. The consent by Landlord to any assignment, mortgaging, subletting or use or occupancy by others shall not in any way be considered to relieve Tenant from obtaining the express written consent of Landlord to any other or further assignment, mortgaging or subletting or use or occupancy by others not expressly permitted by this Article 11. References in this Lease to use or occupancy by others (that is, anyone other than Tenant) shall not be construed as limited to subtenants and those claiming under or through subtenants but shall be construed as including also licensees and others claiming under or through Tenant, immediately or remotely.

11.05.Any permitted assignment or transfer, whether made with Landlord’s consent or without Landlord’s consent, shall be made only if, and shall not be effective until, the assignee or transferee shall execute, acknowledge and deliver to Landlord an agreement in form and substance satisfactory to Landlord whereby the assignee or transferee shall assume Tenant’s obligations under this Lease from and after the effective date of the assignment or transfer and whereby the assignee or transferee shall agree that all of the provisions in this Article 11 shall, notwithstanding such assignment or transfer, continue to be binding upon it in respect to all future assignments and transfers. Notwithstanding any assignment or transfer, whether or not in violation of the provisions of this Lease, and notwithstanding the acceptance of Rent by Landlord from an assignee, transferee, or any other party, the original Tenant and any other person(s) who at any time was or were Tenant shall remain fully liable for the payment of the Rent and for Tenant’s other obligations under this Lease.

11.06.The liability of the originally named Tenant and any other Person(s) who at any time was or were Tenant for Tenant’s obligations under this Lease shall not be discharged, released or impaired by any agreement or stipulation made by Landlord extending the time of, or modifying any of the obligations of, this Lease, or by any waiver or failure of Landlord to enforce any of the obligations of this Lease.

11.07.The listing of any name other than that of Tenant, whether on the doors of the Demised Premises or the Building directory, or otherwise, shall not operate to vest any right or interest in this Lease or in the Demised Premises, nor shall it be deemed to be the consent of

16

Landlord to any assignment or transfer of this Lease or to any sublease of the Demised Premises or to the use or occupancy thereof by others.

11.08.In the event of any assignment or sublease of the Demised Premises which requires the payment of Fixed Rent, Additional Rent and other charges in excess of the amounts payable to the Landlord as set forth in this Lease, then the “net excess or profit” shall be divided and paid equally to Landlord and Tenant. In the event the Tenant fails to make payment of such excess or profit in violation of this Lease, Landlord may collect such rent directly from the assignee or subtenant. The “net excess or profit” shall mean the amount remaining after payment of Fixed Rent, Additional Rent and other standard, customary, and reasonable charges, marketing, brokerage and other professional fees and expenses reasonably incurred by Tenant.

This release shall apply to the extent that such injury, loss or damage to person or property is covered and actually paid by insurance, regardless of whether such insurance is payable to or protects Landlord, Tenant or both. Nothing herein shall be construed to impose any other or greater liability upon Landlord than would have existed in the absence of this provision. Further, Tenant shall require its insurers to include in all of Tenant’s insurance policies which could give rise to a right of subrogation against Landlord, Superior Mortgagee and Superior Lessor a clause or endorsement whereby the insurer waives any rights of subrogation against Landlord, Superior Mortgagee and such Superior Lessor or permits the insured, prior to any loss, to agree with a third party to waive any claim it may have against said third party without invalidating the coverage under the insurance policy.

No diminution or abatement of Fixed Rent, Additional Rent, or other compensation shall be or will be claimed by Tenant, nor shall this Lease or any of the obligations of Tenant hereunder be affected or reduced by reason of such interruptions, stoppages or curtailments, the causes of which are hereinabove enumerated, nor shall the same give rise to a claim in Tenant’s favor that such failure constitutes

24

actual or constructive, total or partial eviction from the Demised Premises, unless such interruptions, stoppages or curtailments have been due to the intentional or willful misconduct of Landlord.

18.04.Landlord shall not be liable or responsible to Tenant in any way for any loss, damage or expense which Tenant may sustain or incur as a result of any (i) interruption, curtailment or failure (whether or not temporary) or (ii) defect in the supply, character, quantity, availability or suitability of electricity (including generator power) furnished to the Demised Premises by reason of any requirement, act or omission of the Electric Service Provider or any other company servicing the Building with electricity or for the performance of any maintenance or repair required hereunder or for any other reason except if and to the extent the same is caused by or results from the intentional or willful misconduct of Landlord.

18.05.If either the quantity or character of electrical service is changed by the Electric Service Provider or other company supplying electricity to the Building or is no longer available or suitable for Tenant’s requirements, no such change, unavailability or unsuitability shall constitute an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution in the payment of Fixed Rent, or relieve Tenant from any of its obligations under this Lease, or impose any liability upon Landlord, or its agents, by reason of inconvenience or annoyance to Tenant, or injury to or interruption of Tenant’s business, or otherwise.

18.06.Tenant shall pay, as and for Additional Rent, all charges imposed by the Electric Service Provider servicing the Demised Premises and the Building promptly when due based upon a submeter installed by Tenant at its sole cost and expense.

In the event that Tenant does not pay the Additional Rent owing by Tenant or pay the Electric Service Provider pursuant to this Article within ten (10) Business Days after the request for same by Landlord, Landlord may, without further notice and in addition to any other remedies Landlord may have, discontinue the service of electricity to the Demised Premises without releasing Tenant from any liability under this Lease and without Landlord incurring any liability for any damage or loss sustained by Tenant as the result of such discontinuance. If any tax is imposed upon Landlord’s receipts from the sale or resale of electric current to Tenant by any Federal, state or municipal authority, Tenant agrees that, unless prohibited by law, Tenant’s proportionate share of such tax shall be passed on to, and included in the bill of, and paid by Tenant to Landlord as Additional Rent. Tenant hereby agrees to indemnify, defend and hold Landlord harmless from and against any claims, damages, lawsuits, penalties, interest or other charges imposed by the Electric Service Provider as a result of electrical energy utilized by the Tenant and directly charged to Tenant by the Electric Service Provider.

18.07.Except as otherwise provided, Tenant will make no electrical installations, alterations, additions or changes to electrical equipment or appliances without the prior written consent of Landlord in each instance which consent shall not be unreasonably withheld or delayed. Tenant will at all times comply with the rules, regulations, terms and conditions applicable to service, equipment, wiring and requirements of the Electric Service Provider

25

supplying electricity to the Building. Tenant covenants and agrees that at all times its use of electric current will not exceed the capacity of existing feeders to the Building or the risers or wiring installation and Tenant will not use any electrical equipment which, in Landlord’s reasonable judgment, will overload such installations or interfere with the use thereof by other tenants of the Building. In the event that, in Landlord’s reasonable judgment, Tenant’s electrical requirements necessitate installation of an additional riser, risers or other proper and necessary equipment, the same shall be installed by Landlord at Tenant’s sole expense and shall be chargeable and collectible as Additional Rent and paid within ten (10) days after the rendition of a bill to Tenant therefor.

18.08.Tenant, at Tenant’s sole cost and expense, shall be permitted to connect to Landlord’s generators and fuel tank system at a cost of $750 per amp of capacity, plus a pro rata share of the actual cost to maintain and operate the generators.

29

reoccupied portion based upon the proportion which the area of the reoccupied portion of the Demised Premises bears to the total area of the Demised Premises, shall be payable by Tenant from the date of such occupancy.

24.04.Tenant shall not be entitled to terminate this Lease and no damages, compensation or claim shall be payable by Landlord for inconvenience, loss of business or annoyance arising from any repair or restoration of any portion of the Demised Premises or of the Building pursuant to this Article 24.

Landlord shall not be required to restore fixtures, improvements or other property of Tenant. The word “restore” as used in this Article shall include repairs.

24.05.Notwithstanding any of the foregoing provisions of this Article 24, if solely by reason of some intentional act or omission on the part of Tenant or any of its subtenants or its or their partners, directors, officers, servants, employees, agents or contractors, either (a) Landlord, any Superior Lessor or any Superior Mortgagee shall be unable to collect all of the insurance proceeds (including without limitation, rent insurance proceeds) applicable to damage or destruction of the Demised Premises or the Building by fire, earthquake or other casualty, or (b) the Demised Premises or the Building shall be damaged or destroyed or rendered completely or partially untenantable on account of fire, earthquake or other casualty, then without prejudice to any other remedies which may be available against Tenant, there shall be no abatement or reduction of Rent.

24.07.The provisions of this Article 24 shall be deemed an express agreement governing any case of damage or destruction of the Demised Premises and/or Building by fire, earthquake or other casualty, and any law providing for such contingency in the absence of an express agreement, now or hereafter in force, shall have no application in such case.

ARTICLE 25
EMINENT DOMAIN

25.01.If the whole of the Demised Premises shall be taken by any public or quasi-public authority under the power of condemnation, eminent domain or expropriation, or in the event of conveyance of the whole of the Demised Premises in lieu thereof, this Lease shall terminate as of the day possession shall be taken by such authority. If 25% or less of the square footage of the Demised Premises shall be so taken or conveyed, this Lease shall terminate only in respect of the part so taken or conveyed as of the day possession shall be taken by such authority.

Except as specifically provided herein, in the event of any such taking or conveyance there shall be no reduction in Rent. If this Lease shall continue in effect, Landlord shall, at its expense, but shall be obligated only to the extent of the net award or other compensation (after deducting all expenses in connection with obtaining the award or other compensation), available to Landlord for the improvements taken or conveyed (excluding any award or other compensation for land or for the unexpired portion of the term of any Superior Lease), make all necessary alterations so as to constitute the remaining Building a complete architectural and tenantable unit, except for the Tenant’s Property, and Tenant shall make all alterations or replacements to the Tenant’s Property and decorations in the Demised Premises. All awards and compensation for any taking or conveyance, whether for the whole or a part of the Land or Building, the Demised Premises or otherwise, shall be the property of Landlord, and Tenant hereby assigns to Landlord all of Tenant’s right, title and interest in and to any and all such awards and compensation, including, without limitation, any award or compensation for the value of the unexpired portion of the Term. Tenant shall be entitled to claim, prove and receive in the condemnation proceeding such award or compensation as may be separately awarded by the court for the Tenant’s non-depreciated leasehold improvements and for loss of business, goodwill, and depreciation or injury to and cost of removal of the Tenant’s Property.

CONDITIONS OF LIMITATION

27.01.This Lease is subject to the limitation that whenever Tenant or a guarantor, if any, (a) shall make an assignment for the benefit of creditors, or (b) shall commence a voluntary case or have entered against it an order for relief under any chapter of the Federal Bankruptcy Code (Title 11 of the United States Code) or any similar order or decree under any federal or state law, now in existence or hereafter enacted having the same general purpose, and such order or decree shall have not been stayed or vacated within 30 days after entry, or (c) shall cause, suffer, permit or consent to the appointment of a receiver, trustee, administrator, conservator, sequestrator, liquidator or similar official in any federal, state or foreign judicial or nonjudicial proceeding, to hold, administer and/or liquidate all or substantially all of its assets, and such appointment shall not have been revoked, terminated, stayed or vacated and such official discharged of his duties within 30 days of his appointment, then Landlord, at any time after the occurrence of any such event, may give Tenant a notice of intention to end the Term at the expiration of five (5) days from the date of service of such notice of intention, and upon the expiration of said five (5) day period, whether or not the Term shall theretofore have commenced, this Lease shall terminate with the same effect as if that day were the Expiration Date of this Lease, but Tenant shall remain liable for damages as provided in Article 29.

27.02.This Lease is subject to the further limitations that: (a) if Tenant shall default in the payment of any Rent, and such default shall continue for ten (10) days after the due date, or (b) if Tenant shall, whether by action or inaction, be in default of any of its obligations under this Lease (other than a default in the payment of Rent) and such default shall continue and not be remedied within thirty (30) days after Landlord shall have given to Tenant a notice specifying the same, or, in the case of default which cannot with due diligence be cured within a period of thirty (30) days and the continuance of which for the period required for cure will not subject Landlord, Superior Mortgagor or Superior Lessor to prosecution for a crime (as more particularly described in the last sentence of Section 12.02.) or termination of any Superior Lease or foreclosure of any Superior Mortgage, if Tenant shall not, (i) within said ten (10) day period advise Landlord of Tenant’s intention to take all steps necessary to remedy such default, (ii) duly commence within said ten (10) day period and thereafter diligently prosecute to completion all steps necessary to remedy the default, and (iii) to complete such remedy within a reasonable time after the date of said notice by Landlord, or (c) if any event shall occur or any contingency shall arise whereby this Lease would, by operation of law or otherwise, devolve upon or pass to any person, firm or corporation other than Tenant, except as expressly permitted by Article 11, or (d) if Tenant shall abandon the Demised Premises, then in any of said cases Landlord may give to Tenant a notice of intention to end the Term at the expiration of five (5) days from the date of the service of such notice of intention, and upon the expiration of said five (5) days, whether or not the Term shall theretofore have commenced, this Lease shall terminate with the same effect as if that day were the Expiration Date of this Lease, but Tenant shall remain liable for damages as provided in Article 29. The indemnity provisions contained herein shall survive the expiration or earlier termination of this Lease.

ARTICLE 28
RE-ENTRY BY LANDLORD

28.01.If Tenant shall default in the payment of any Rent, and such default shall continue for ten (10) days after notice thereof, or if this Lease shall terminate as provided in Article 27, Landlord or Landlord’s agent and employees may immediately or at any time thereafter re-enter the Demised Premises, or any part thereof, either by summary dispossess proceedings or by any suitable action or proceeding at law, or otherwise, without terminating the Lease and without being liable to indictment, prosecution or damages therefor, and may repossess the same, and may remove any Person therefrom, to the end that Landlord may have, hold and enjoy the Demised Premises. The word “re-enter” as used herein, is not restricted to its technical legal meaning. If this Lease is terminated under the provisions of Article 27, or if Landlord shall re-enter the Demised Premises under the provisions of this Article 28, or in the event of the termination of this Lease, or of re-entry, by or under any summary dispossess or other proceedings or action or any provision of law by reason of default hereunder on the part of Tenant, Tenant shall thereupon pay to Landlord the Rent payable up to the time of such termination of this Lease, or of such recovery of possession of the Demised Premises by Landlord, as the case may be, and shall also pay to Landlord damages as provided in Article 29.

28.02.In the event of a breach or threatened breach by a party of any of its obligations under this Lease, the other party shall also have the right of injunction.

33

28.03.If this Lease shall terminate under the provisions of Article 27, or if Landlord shall re-enter the Demised Premises under the provisions of this Article 28, or in the event of the termination of this Lease, or re-entry, by or under any summary dispossess or other proceeding or action or any provision of law by reason of default hereunder on the part of Tenant, Landlord shall be entitled to retain all monies, if any, paid by Tenant to Landlord whether as Advance Rent, Security Deposit (and interest thereon, if any) or otherwise, but such monies shall be credited by Landlord against any Rent due from Tenant at the time of such termination or re-entry or, at Landlord’s option, against any damages payable by Tenant under Article 29 or pursuant to law.

ARTICLE 29
DAMAGES

29.01.If this Lease is terminated under the provisions of Article 27, or if Landlord shall re-enter the Demised Premises under the provisions of Article 28, or in the event of the termination of this Lease, or of re-entry, by or under any action to obtain possession in a summary manner or other proceeding or action or any provision of law by reason of default hereunder on the part of Tenant, Tenant shall pay as Additional Rent to Landlord as a condition precedent to the dismissal of any action to obtain possession of the Demised Premises or other proceeding or action for damages, at the election of Landlord, either:

(a)A sum which at the time of such termination of this Lease or at the time of any such re-entry by Landlord, as the case may be, represents the then present value, calculated utilizing the prime interest rate declared by Chase Bank, N.A. in New York as of the date of default, of the aggregate amount of the Rent which would have been payable by Tenant (conclusively presuming the average monthly Additional Rent to be the same as were the average monthly Additional Rent payable for the year, or if less than 365 days have then elapsed since the Commencement Date, the partial year, immediately preceding such termination or re-entry) for the period commencing with such earlier termination of this Lease or the date of any such re-entry, as the case may be, and ending with the Expiration Date plus legal and expert fees and costs for the bringing of any action to enforce this provision. In exercising this remedy, Landlord shall be entitled to accelerate all unpaid Rent and other amounts due hereunder until the Expiration Date; or

(b)Sums equal to the Fixed Rent and the Additional Rent which would have been payable by Tenant had this Lease not so terminated, or had Landlord not so re-entered the Demised Premises, payable upon the due dates therefor specified herein following such termination or such re-entry and until the Expiration Date, provided, however, that if Landlord shall relet the Demised Premises during said period, Landlord shall credit Tenant with the net rents received by Landlord from such reletting, such net rents to be determined by first deducting from the gross rents as and when received by Landlord from such reletting the expenses incurred or paid by Landlord in terminating this Lease or in reentering the Demised Premises and in securing possession thereof, as well as the expense of reletting, including, without limitation, altering and preparing the Demised Premises for new tenants, brokers’ commissions, legal fees, and all other expenses properly

34

chargeable against the Demised Premises and the rental therefrom, it being understood that any such reletting may be for a period shorter or longer than the period ending on the Expiration Date; but in no event shall Tenant be entitled to receive any excess of such net rents over the sums payable by Tenant to Landlord hereunder, nor shall Tenant be entitled in any suit for the collection of damages pursuant to this subdivision (b) to a credit in respect of any rents from reletting, except to the extent that such net rents are actually received by Landlord. If the Demised Premises or any part thereof should be relet in combination with other space, then proper apportionment on a square foot basis shall be made of the rent received from such reletting and of the expenses of reletting.

If the Demised Premises or any part thereof be relet by Landlord before presentation of proof of such damages to any Court, commission or tribunal, the amount of rent reserved upon such reletting shall, prima facia, be the fair and reasonable rental value for the Demised Premises, or part thereof, to relet during the term of the reletting. Landlord shall have no obligation to mitigate damages by reletting the Demised Premises and shall not be liable in any way whatsoever for its failure or refusal to relet the Demised Premises or any part thereof, or if the Demised Premises or any part thereof are relet, for its failure to collect the rent under such reletting, and no such failure or refusal to relet or failure to collect the rent shall release or affect Tenant’s liability for damages or otherwise under this Lease. Landlord shall be under no obligation in reletting the Demised Premises to give priority to the leasing thereof over other vacant space in the Building.

29.02.Suit or suits for the recovery of any such damages, or any installments thereof, may be brought by Landlord at any time and from time to time at its election, and nothing contained herein shall be deemed to require Landlord to postpone suit until the date when the Term would have expired if it had not been so terminated under the provisions of Article 27 or under any provision of law, or had Landlord not re-entered the Demised Premises. Nothing herein contained shall be construed to limit or preclude recovery by Landlord against Tenant of any sums or damages to which, in addition to the damages particularly provided above, Landlord may lawfully be entitled by reason of any default hereunder on the part of Tenant. Nothing herein contained shall be construed to limit or prejudice the right of Landlord to prove and/or obtain as damages by reason of the termination of this Lease or re-entry on the Demised Premises for the default of Tenant under this Lease an amount equal to the maximum amount permitted by any statute or rule of law in effect at the time when the governing proceedings have been initiated, whether or not such amount is greater than, equal to, or less than any of the sums referred to in Section 29.01.

29.03.In addition, if this Lease is terminated under the provisions of Article 27, or if Landlord shall re-enter the Demised Premises under the provisions of Article 28, Tenant covenants that: (a) the Demised Premises then shall be in the same condition as that in which Tenant has agreed to surrender the same to Landlord at the Expiration Date; (b) Tenant shall have performed prior to any such termination any obligation of Tenant contained in this Lease for the making of any alteration or for restoring or rebuilding the Demised Premises or the Building, or any part thereof; and (c) for the breach of any covenant of Tenant set forth above in this Section 29.03, Landlord shall be entitled immediately without notice or other action by

35

Landlord, to recover, and Tenant shall pay as and for liquidated damages therefor, the cost of performing such covenant (as estimated by an independent contractor selected by Landlord).

29.04.In addition to any other remedies Landlord may have under this Lease, and without reducing or adversely affecting any of Landlord’s rights and remedies under this Article 29, if any Rent or damages payable hereunder by Tenant to Landlord are not paid within five (5) days after notice therefor, the same shall bear interest at the Late Payment Rate pursuant to Section 3.05 from the due date thereof until paid, and the amount(s) of such interest shall be Additional Charges hereunder.

29.05.In addition to any remedies which Landlord may have under this Lease, if there shall be a default hereunder by Tenant which shall not have been remedied within the applicable grace period, Landlord shall not be obligated to furnish to Tenant or the Demised Premises any HVAC services, or any building services; and the discontinuance of any one or more of such services shall be without liability by Landlord to Tenant and shall not reduce, diminish or otherwise affect any of Tenant’s covenants and obligations under this Lease.

The receipt by Landlord of Fixed Rent or Additional Rent with knowledge of breach by Tenant of any obligation of this Lease shall not be deemed a waiver of such breach.

ARTICLE 32
CURING TENANT’S DEFAULTS

32.01.If Tenant shall default in the performance of any of Tenant’s obligations under this Lease, Landlord, without thereby waiving such default, may (but shall not be obligated to) perform the same for the account and at the expense of Tenant, without notice in a case of emergency, and in any other case only if such default continues after the expiration of ten (10) days from the date Landlord gives Tenant notice of the default.

ARBITRATION

36.01.Landlord may at any time request arbitration, and Tenant may at any time when not in default in the payment of any Rent request arbitration, of any matter in dispute but only where arbitration is expressly provided for in this Lease. Such dispute shall be submitted to the arbitration of three (3) disinterested persons, one of whom shall be chosen by each of the parties hereto, and the third by the two arbitrators so chosen; and the award and finding of said arbitrators, or of any two of them, shall be final and conclusive on any questions or matters so submitted to them. In case an arbitration is not otherwise arranged, either party desiring such submission to arbitration shall notify the other party in writing of the matter which it desires to submit to arbitration, designating its arbitrator in such notice. Within twenty (20) days thereafter, the party thus notified shall name its arbitrator, and notify the other party of such selection. The arbitrators thus selected shall immediately proceed to select the third arbitrator as aforesaid, and with him to consider and determine all matters submitted. In case the party notified of the desired submission to arbitration shall fail, upon due notification, to name an arbitrator, the arbitrator selected by the other party shall have the right to proceed alone and determine the matters thus submitted, and his award shall be final and conclusive upon the parties hereto. In the event that the two arbitrators first selected shall be unable to agree upon the third arbitrator within twenty (20) days after the selection of the second arbitrator, either party hereto, upon giving ten (10) days’ notice in writing to the other party, or to the arbitrator selected by such other party, may apply to the Courts of the State of Washington for the appointment of a third arbitrator, and any arbitrator appointed by such Court upon such application shall have the same powers and duties as if appointed by the two arbitrators first selected as hereinbefore provided. The award in such arbitration may be enforced on application of either party by the order or judgment of a Court of competent jurisdiction.

36.02.If any delay in complying with any requirement of this Lease by Landlord might subject Tenant to any fine or penalty, or to prosecution for a crime, or materially interfere with Tenant’s use and enjoyment of the Demised Premises or its access thereto, of if it would constitute a default by Tenant under any permitted mortgage, or of any of the foregoing, Tenant shall have the right to remedy such default and in such event the sole question to be determined by the arbitrators shall be whether Landlord is liable for Tenant’s costs and expenses of curing such default.

36.03.Each party to the arbitration shall pay the costs or fees of the arbitrator selected by it and all further costs and fees, including Court costs in connection with the arbitration, shall be shared equally by the two parties to the arbitration. Each party shall bear the cost of its own attorneys and experts and the additional expenses of presenting its own proofs. Any arbitration under this Article shall be governed and controlled, except as otherwise provided herein, by the rules of the American Arbitration Association in the City of Seattle, Washington.

ARTICLE 37

39

this Lease. Tenant shall give written notice to the Landlord (“Renewal Notice”) at least 270 days prior to the Expiration Date with respect to the First Renewal Period or twelve 270 days prior to the expiration of the First Renewal Period with respect to the Second Renewal Period. Except for this Article 37 and, further except for the amount of Fixed Rent as set forth in Article 1, all other terms and conditions of this Lease shall continue during the First Renewal Period and the Second Renewal Period. The Fixed Rent shall be the fair market rental for comparable space within the Building. In the event that the parties are unable to agree as to the fair market rent within sixty (60) days after the date of the Renewal Notice, then the Fixed Rent shall be determined by an independent appraiser selected by Landlord in its sole reasonable discretion which appraiser shall have at least fifteen (15) years experience in the real estate industry of Seattle, Washington and shall be familiar with the real estate requirements of the telecommunications industry. The determination of such appraiser shall be binding on the parties; however, in no event shall Fixed Rent for any Renewal Period be less than the Fixed Rent for the Initial Term of the Lease or the immediately prior Renewal Period, as the case may be.

ARTICLE 38
BUILDING NAME

38.01.The Building may be designated and known by any name or address Landlord may choose from time to time in Landlord’s sole discretion. Tenant agrees not to refer to the Building by any name or address other than as designated by Landlord. The Building may be named after any person, firm, or otherwise, whether or not such name is, or resembles, the name of a tenant of the Building. In no event shall Tenant use, in connection with its business or otherwise, any photographic or other type of representation of the Building. In the event the Building is named after any person, firm or otherwise, Tenant, in connection with its business or otherwise, shall not refer to the Building by such name but shall only use the street address of the Building.

In the event an environmental clean-up is required, the Landlord shall have an unrestricted right to inspect, as often as it deems necessary in its sole discretion, during and after such clean-up.

39.03.Tenant hereby agrees to execute such documents and provide such information as Landlord reasonably requires to assure compliance with the Environmental Laws, and rules or regulations of any other relevant federal, state, county or municipal legal authority.

Landlord shall not be considered in default so long as Landlord commences to cure the breach in a diligent and prudent manner and is allowed such additional time as is reasonably necessary to correct the breach.
