RENT All payments due hereunder from Tenant shall be made to Landlord's agent at the office of the Building, or to such other persons or at such other place as Landlord may from time to time designate in writing, in coin or currency which, at the time of payment, is legal tender for private or public debts in the United States of America. All payments due hereunder shall be made without demand or notice except as expressly required under this Lease, and without any abatement, set_off offset or deduction whatsoever, except as expressly provided for under this Lease or in any other agreement expressly referred to herein.

E. A late fee equal to five percent (5%) of any payment, or portion thereof, becoming due under this Lease which payment is not paid by the seventh (7th) day following its due date; provided, however, that regardless of whether such late fee constitutes or is deemed to be interest under applicable law, the sum of all interest contracted for, charged or received hereunder shall not exceed the maximum amount of interest allowed under applicable law. Without limiting any of the other obligations of Tenant which survive the expiration or earlier termination of this Lease, Tenant's obligation to pay all Rent due under this Lease shall survive the expiration or earlier termination of this Lease. 4. ADDITIONAL RENT In addition to paying the Annual Base Rent specified in Paragraph 3A hereof, Tenant shall pay as "Additional Rent" the amounts determined pursuant to the succeeding provisions of this Paragraph 4.

If Landlord has not notified Tenant of the amount of each monthly installment of Additional Rent payable during a particular Lease Year as described below by the commencement of such Lease Year, Tenant shall continue to make each monthly installment payment of Additional Rent thereafter in the amount set forth in the latest notice or notices from Landlord.

provided, however, except for those costs related to the Americans With Disabilities Act (which shall not exceed $15,000 per Lease Year of such $25,000 per Lease Year amount) any costs included under clause (II) above shall be limited to those costs arising only as a result of a change in any governmental rule or regulation; (c) Any damage or loss to property insured by Landlord pursuant to this Lease resulting from a fire or other casualty, except for any such damage or loss in the amount of Landlord's insurance deductibles paid by Landlord per incident, which shall be limited to $.15 per rentable square foot in the Building;

(j) The cost increment paid for services in the Building, including, without limitation, management of the Building, to the extent the costs of such services exceed the costs of the same quality of such services rendered on a competitive basis by third parties who are not Affiliates of Landlord; (k) Any compensation paid to clerks, attendants or other persons in, and any costs attributable solely to, commercial concessions operated by Landlord or in the parking garage of the Building; (l) All items and services for which Tenant or any other tenant in the Building reimburses Landlord or which Landlord provides selectively to one or more tenants (other than Tenant) without reimbursement;

The Operating Expense Stop shall be increased by the product that results from multiplying the sum of the following, to the extent they were not included in Operating Expenses of the Property -12- during the 1996 calendar year: (i) amounts that ordinarily would be included in Operating Expenses for the 1996 calendar year that were not included therein due to warranties or guarantees, and (ii) the cost of a full and normal management and maintenance staff for the Property during the 1996 calendar year. Landlord represents and warrants to Tenant that Landlord currently provides to tenants of the Building and will, throughout the Term of this Lease provide to Tenant all services ordinarily and customarily provided by a Landlord of a first-class office building in Arlington County, Virginia. It is understood that Operating Expenses shall be reduced by all cash discounts, trade discounts or quantity discounts received by Landlord or any Affiliate of Landlord or the manager of the Property in the purchase of any goods, utilities or services in connection with the operation of the Building or the Property. Landlord shall use reasonable efforts to make payments for goods, utilities and services in a timely manner and to obtain the maximum possible discount, to the extent it is commercially reasonable under the circumstances to do so, in Landlord's reasonable determination. Landlord agrees that, in the calculation of any costs or expenses to be included in Operating Expenses, no cost or expense shall be included more than once. Landlord shall use reasonable efforts to effect an equitable pro-ration of bills for services rendered to the Building and to any other Property owned by Landlord. Landlord shall use reasonable efforts to establish accurate estimates of the Operating Expenses for each Lease Year so as to be reasonably close to the actual Operating Expenses for such Lease Year. B. EXPENSE ADJUSTMENT. Tenant shall pay, as Additional Rent, an amount (hereinafter referred to as the "(Expense Adjustment Amount") equal to Tenant's Share of the amount by which the Operating Expenses (subject to adjustment pursuant to Paragraph 4C hereof) incurred with respect to each Lease Year after the first Lease Year exceed the Operating Expense Stop set forth in the Schedule. If less than ninety-five percent (95%) of the Building's total rentable area shall have been occupied by tenants at any time during any Lease Year, then the Expense Adjustment Amount shall be increased to an amount which Landlord in good faith and in accordance with sound accounting principles, consistently applied, determines the Expense Adjustment Amount would have been for such Lease Year had occupancy of the Building been ninety-five percent (95%) throughout such Lease Year. if the Lease Year in which the last day of the Term occurs is shorter than twelve (12) months, the Operating Expense Stop shall be prorated based on the number of days in such Lease Year. The Expense Adjustment Amount with respect to each Lease Year shall be paid in monthly installments in advance on the first day of each and every calendar month during such Lease Year, in an amount estimated from time to time by Landlord and communicated by written notice to Tenant. Landlord shall cause to be kept books and records showing Operating Expenses in accordance with sound accounting principles, consistently applied. Landlord shall deliver to Tenant a reasonably detailed statement setting forth (a) the actual Operating Expenses and Expense Adjustment Amount for such Lease Year; (b) the total of the estimated monthly installments of the Operating Expense Adjustment Amount paid to Landlord for such Lease Year; and (c) the amount of any excess or deficiency of Expense Adjustment Amount previously paid with respect to such Lease Year. Tenant shall pay any deficiency to Landlord as shown by such statement within thirty (30) days after receipt of -13- such statement. Upon Tenant's written request, Landlord shall furnish Tenant with copies of all relevant tax bills with such statement. If the total of the estimated monthly installments paid by Tenant during any Lease Year exceeds the actual Expense Adjustment Amount due from Tenant for such Lease Year, such excess shall be refunded by Landlord within thirty (30) days after delivery to Tenant of such statement, provided Tenant is not then in default hereunder. In lieu of receiving such overpayment, provided Tenant is not then in default hereunder, Tenant, upon Landlord's prior written approval, may deduct the amount of such overpayment from the succeeding installment of Annual Base Rent or Additional Rent coming due hereunder. Tenant shall have no right to audit or inspect the records of Landlord or the Property, except as expressly provided in Exhibit C attached hereto. C. ADJUSTMENT TO EXPENSE CALCULATIONS. If less than ninety-five percent (95%) of the Building's total rentable area shall have been occupied by tenants at any time during any Lease Year, then Operating Expenses for such Lease Year shall be an amount which Landlord in good faith determines is the amount Operating Expenses would have been for such Lease Year had occupancy of the Budding been ninety-five percent (95%) throughout such Lease Year. Tenant acknowledges that the method of computing the amount of Operating Expenses, prior to any adjustment, as stated in Paragraph 4B hereof, is based upon the assumption that Landlord will be providing identical services to all tenants in the Building. 5. USE OF LEASED PREMISES Tenant shall use and occupy the Leased Premises as an office for the type of business set forth in the Schedule and no other purpose. Tenant shall not use or occupy the Leased Premises for any unlawful purpose or in any manner that will constitute waste, nuisance or unreasonable annoyance to Landlord or other tenants of the Property. Tenant shall comply with all present and future laws, ordinances, regulations, and orders of the United States of America, state and county government, and any other public or quasi-public authority having jurisdiction over the Property, concerning the use, occupancy and condition of the Leased Premises and all machinery, equipment and furnishings therein. It is expressly understood that if any present or future law, ordinance, regulation or order of any public or quasi-public authority having jurisdiction over the Property requires a certificate of occupancy or use permit for the Leased Premises, except for any certificate of occupancy or other evidence that the Leased Premises may be lawfully occupied upon completing the Landlord's Work, Tenant will obtain such certificate or permit at Tenant's own expense and will deliver a copy thereof to Landlord promptly when it is obtained. The cost of such compliance by Tenant shall be borne by Tenant under all circumstances, except as expressly provided to the contrary in Paragraph 8 of this Lease or unless such compliance is required as a result of Landlord's negligence or willful misconduct or by a breach by Landlord of any of Landlord's obligations hereunder. -14- 6. CONDITION OF LEASED PREMISES The improvement of the Leased Premises by Landlord shall be accomplished in accordance with Exhibit B attached hereto. In no event shall Tenant be entitled to any credit against, or abatement of, Rent due to the existence of any PunchList Items. No promise of Landlord to alter, remodel or improve the Leased Premises or the Property and no representation by Landlord or its agents respecting the condition of the Leased Premises or the Property has been made to Tenant or relied upon by Tenant other than as may be contained in Exhibit B attached to this Lease. By taking possession of the Leased Premises, the Tenant accepts the Leased Premises in the Building in its "As Is" condition, and the taking of the possession of the Leased Premises by the Tenant shall be conclusive evidence that the Leased Premises and the Building are in good and satisfactory condition, except for Latent Defects and uncompleted PunchList Items. Landlord shall complete the PunchList Items within forty-five (45) days following Landlord's approval, which approval shall not be unreasonably withheld, delayed or conditioned, of a list of the PunchList Items submitted to Landlord by Tenant after the Commencement Date. Such forty-five (45) day period shall be extended to the extent Landlord's completion of the PunchList Items is delayed by any act of God, strike, lock out, labor difficulty, explosion, sabotage, accident, riot, civil commotion, act of war, result of any warfare or warlike condition in this or any foreign country, fire or other casualty, legal requirement, energy shortage or cause beyond the reasonable control of Landlord and Landlord has nevertheless used reasonably diligent efforts to complete any uncompleted PunchList Items. Landlord shall have access to the Leased Premises at all reasonable times in order to complete the PunchList Items. Tenant acknowledges that Landlord's completion of the PunchList Items may cause interference with the conduct of Tenant's business in the Leased Premises and Tenant waives any and all rights and remedies it has with respect to such interference; however, Landlord agrees to use reasonable efforts to minimize such interference. 7. SERVICES A. LIST OF SERVICES. Landlord shall provide the following services on all days during the Term, except Sundays and legal Federal holidays, unless otherwise stated: (i) Heating, ventilation and air conditioning service ("HVAC Service") when necessary for normal comfort in the Leased Premises, from Monday through Friday, during the period from 7:00 a.m. to 6:00 p.m. and on Saturday during the period from 9:00 a.m. to 1:00 p.m. (such periods are hereinafter referred to as "Standard Building Hours"). Subject to the terms and provisions of this Lease, Landlord shall furnish HVAC Service to the Leased Premises during any period of time other than Standard Building Hours upon Tenant's written request on Landlord's tenant work order form; provided, however, any such request shall be made during, and at least six (6) hours prior to the expiration of, Standard Building Hours on a weekday, other than a Federal holiday. The minimum period of HVAC Service that may be so requested is four (4) consecutive hours. Tenant will pay for all such HVAC Service so requested and furnished at -15- Landlord's actual and direct costs therefor, with no markup by Landlord. To the extent another tenant, on the same floor in the Building as the floor to which Tenant has requested such HVAC Service for a period of time, has requested that such HVAC Service be provided during all or part of the same period, Landlord shall prorate the cost of such simultaneous HVAC Service between Tenant and such other tenant based on the proportionate sizes of Tenant's space and such other tenant's space to which simultaneous HVAC Service was furnished. Notwithstanding the foregoing, Landlord reserves the right to increase the hours and/or days during which the Standard Building Hours of the Building shall occur. The HVAC Service furnished by Landlord to the Leased Premises has been designed to produce indoor conditions noted below when the outdoor conditions are as stated below based upon the average consumption of 5 watts per usable square foot and occupancy averaging not more than one person per 200 usable square feet: Summer: Indoor Conditions (maximum): 73 degrees Fahrenheit, dry bulb Outdoor Conditions: 93 degrees Fahrenheit, dry bulb 75 degrees Fahrenheit, wet bulb (coincidental) Winter: Indoor Conditions (maximum): 72 degrees Fahrenheit, dry bulb Outdoor Conditions: 14 degrees Fahrenheit, dry bulb These specifications define the quality, character and amount of HVAC Service that Landlord is required to supply at the points at which the systems providing HVAC Service in the Building meet the distribution systems for HVAC Service in the Leased Premises. The actual temperature and humidity in the Leased Premises may be varied by, among other things, equipment used by Tenant, alterations made to the Leased Premises and the imposition of different temperature maintenance standards by governmental and quasi-governmental authorities. Landlord shall have no liability or responsibility for any such variation. (ii) Electricity services; provided that (a) the connected electrical load of the lighting and other receptacle equipment in the Leased Premises shall not exceed an average consumption of 5 watts per usable square foot of the Leased Premises; (b) the electricity so furnished will be at a normal 120 volts and no electrical circuit for the supply of the Leased Premises have a current capacity exceeding 20 amperes; (c) no individual piece of electrically -16- operated machinery or equipment shall draw in excess of 2 kilowatts; and (d) such electricity will be used only for equipment and accessories normal to office usage. Tenant shall not install or operate in the Leased Premises any electrically operated equipment or machinery that may exceed the requirements set forth in the preceding sentence without first obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed; provided, however, Landlord may condition such consent upon the payment by Tenant of Additional Rent in compensation for the excess consumption of electricity or other utilities and compliance by Tenant with the terms and provisions of this Lease relating to improvements, alterations and additions with respect to any additional wiring or apparatus that may be occasioned by the operation of such equipment or machinery. Tenant shall bear the cost of replacement of all lamps, tubes, ballasts and starters for lighting fixtures that are not building standard lighting fixtures. (iii) Potable water for drinking in accordance with governmental requirements, hot and cold water from the regular Building lavatory outlets and water from the regular Building toilet outlets. (iv) Cleaning services in accordance with the specifications set forth in Exhibit E. (v) Automatic passenger elevator service. (vi) Elevator service for freight subject to scheduling by Landlord. Landlord agrees to use reasonable efforts to accommodate scheduling requests by Tenant. Tenant's use of elevator service for freight shall not occur during Standard Building Hours or on legal Federal holidays. Tenant shall reimburse Landlord for Landlord's costs incurred in such use. If Tenant, in using an elevator for freight, is vacating the Leased Premises (whether or not such vacation is in violation of the terms of this Lease), Tenant shall pay such cost to Landlord in advance of such vacation. (vii) Security, including, without limitation, a "Kastle Key" access system, or a reasonably equivalent system for building access after, and a lobby attendant during, Standard Building Hours, as well as a building security system, a fire safety system and an elevator floor "lock out" system. (viii) Structural repairs to the base Building shell and Base Construction. B. EXCESS CONSUMPTION. Subject to the provisions of Paragraph 7A(ii) above, at the option and cost of Landlord, Landlord may install checkmeters to electrical circuits serving Tenant's equipment to determine whether Tenant is consuming excessive electricity as compared to typical office tenants in Arlington County, Virginia. If Landlord determines pursuant thereto that Tenant's electricity consumption is excessive, Landlord may install submeters, at Tenant's -17- sole cost and expense (which shall be Additional Rent), to ascertain Tenant's actual electricity consumption, and Tenant will thereafter pay for Tenant's excess consumption of electricity, at the then current price per kilowatt hour for the commercial service classification charged Landlord by the utility, as Additional Rent. C. INTERRUPTION OF SERVICES. Tenant agrees that Landlord shall not be liable in damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service or for any diminution in the quality or quantity thereof, when such failure, delay or diminution is occasioned, in whole or in part, by maintenance, repairs, replacements, additions, alterations or improvements, by any strike, lockout or other labor trouble, by inability to secure water or electricity, gas (if any) or other fuel at the Building after reasonable effort so to do, by any accident, fire or casualty whatsoever, by act or default of Tenant or any other person or entity, by the exercise of Landlord's rights under Paragraph 7E or by any act or failure to act by any person or entity if it is beyond Landlord's reasonable control and not caused by the negligence or willful misconduct of Landlord, and no such failure, delay or diminution shall ever be deemed to constitute an actual or constructive eviction or disturbance of Tenant's use and possession of the Leased Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease; provided, however, to the extent any such failure, delay or diminution is caused by any circumstance described above, other than a fire or casualty covered by Paragraph 12 hereof, and Tenant's does not use the Leased Premises as a result thereof for a period of at least five (5) consecutive business days after Tenant has given written notice to Landlord of such interruption, then Tenant, as its sole remedy, shall be entitled to full abatement of Rent payable during the period of time following such five (5) consecutive business day period that such failure, delay or diminution continues as long as Tenant does not use the Leased Premises; provided, further, that in the event such failure, delay or diminution continues uninterrupted for a period of at least sixty (60) consecutive days following Tenant's written notice thereof to Landlord, then if Tenant has not used the Leased Premises during such sixty (60) consecutive day period Tenant shall be entitled to terminate this Lease as an additional remedy by giving to Landlord written notice of such termination prior to the seventieth (70th) consecutive business day of such uninterrupted failure, delay or diminution that Tenant does not use the Leased Premises, and this Lease shall terminate thirty (30) days after Landlord's receipt of such notice from Tenant unless Tenant uses the Leased Premises or such interruption has ceased prior to the expiration of such thirty (30) day period. Upon such termination neither such party shall have any further right or obligation under this Lease, except that each party shall fulfill all obligations of such party which survive the termination of this Lease. D. CHARGES FOR SERVICES. Except as expressly provided herein to the contrary, charges for any service for which Tenant is required to pay from time to time hereunder, including, but not limited to, HVAC Service during any period of time other than Building Standard Hours, shall be due and payable within thirty (30) days after they are billed. If Tenant shall fail to make payment for any such service within such thirty (30) day period, Landlord may, after giving Tenant any ten (10) days notice of such failure and opportunity to -18- cure required under Paragraph 18 of Exhibit C, discontinue any or all of such services until such payment, together with the payment of interest and any late charge due hereunder in connection therewith, is made by Tenant, and such discontinuance shall not be deemed to constitute an actual or constructive eviction or disturbance of Tenant's use and possession of the Leased Premises or relieve Tenant from paying Rent or performing any of its other obligations under this Lease. E. ENERGY AND WATER CONSERVATION. Notwithstanding anything to the contrary in this Paragraph 7 or elsewhere in this Lease, Landlord, in its reasonable discretion, shall have the right to institute such policies, programs and measures as may be necessary or desirable for the conservation and preservation of water, energy or energy related services, or as may be required to comply with any applicable codes, rules and regulations, whether mandatory or voluntary; provided, however, that Landlord agrees that any such policies, programs and measures which are not mandatory shall be made in a manner reasonably intended to minimize inconvenience to Tenant and shall not materially violate the terms of Paragraph 26 of this Lease. 8. REPAIRS Tenant shall use its best efforts to promptly and adequately notify Landlord in writing of any repairs and/or replacements to the Leased Premises or the Landlord's Work that are necessary or appropriate. Upon Landlord obtaining knowledge of any repair and/or replacement to the Leased Premises or the Landlord's Work (but not any alterations, additions or improvements made thereto) that is necessary or appropriate, Landlord will make such repair and/or replacement, except Landlord shall not be obligated to make any repair or replacement that is a result of ordinary wear or tear, or is a repair and/or replacement which Tenant is obligated to make pursuant to this Lease. Provided that Tenant has fulfilled its obligation in the first (1st) sentence of this Paragraph 8, any repair or replacement which Landlord is obligated to make pursuant to this Lease shall be made at Landlord's expense, except as expressly provided to the contrary in this Lease. Tenant shall be liable to Landlord for the cost of any repair or replacement which Landlord is obligated to make under this Paragraph 8 to the extent Tenant's failure to fulfill its obligation in the first (1st) sentence of this Paragraph 8 caused such cost to exceed the cost of such repair or replacement if Tenant had fulfilled such obligation. If Landlord fails to commence efforts to make any repair and/or replacement that Landlord is obligated to make under this Lease, other than a repair and/or restoration covered by Paragraph 12 hereof, within thirty (30) days from the date that Tenant gives Landlord such written notice of Landlord's obligation hereunder to perform any such repair and/or replacement, or within a shorter, reasonable period of time in the event of an emergency, and thereafter continue such efforts until such repair and/or replacement is completed, Tenant then, if such failure continues after Tenant has given Landlord a ten (10) day, or a shorter, reasonable period in the event of a emergency, written notice of Tenant's intent to make such repair and/or replacement, Tenant shall have the right, at its option, to perform such repair and/or replacement -19- if Landlord has not made such repair and/or replacement during such ten (10) day period, subject to the other terms and provisions of this Lease, and Landlord shall reimburse Tenant the reasonable cost thereof approved in advance by Landlord in writing, and such approval shall not be unreasonably withheld, delayed or conditioned. Except in an emergency, prior to performing any repair and/or replacement allowed under this Lease, Tenant shall obtain Landlord's prior written approval, which approval shall not be unreasonably withheld, delayed or conditioned, of the contractor and each subcontractor which shall perform any part of such repair and/or replacement. Anything in this Lease to the contrary, notwithstanding, Tenant shall be obligated to perform and pay the cost of any repair and/or replacement to the Leased Premises, the improvements provided in connection with the Landlord's Work and any alterations, additions or improvements made to the Landlord's Work, the Building or the Property necessitated by the negligence or willful misconduct of Tenant, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests. If Tenant fails to commence efforts to make any repair and/or replacement Tenant is obligated to perform under this Lease within thirty (30) days from the date that Landlord gives Tenant written notice of Tenant's obligation hereunder to perform any such repair and/or replacement, or within a shorter, reasonable period of time in the event of an emergency, and thereafter continue such efforts until such repair and/or replacement is completed, Landlord and its designee shall have the right, at Landlord's option, to enter the Leased Premises and perform such repair and/or replacement and Tenant shall pay Landlord the reasonable costs thereof, including, without limitation, a percentage of the costs thereof [such percentage to be established by Landlord from time to time on a uniform basis for the Building, but such percentage shall not exceed ten percent (10%)] sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs and expenses arising from the supervision of such repair and/or replacement by Landlord or Landlord's designee, promptly upon being billed for same. Notwithstanding the foregoing in this Paragraph 8, Landlord may, but shall not be required to, enter the Leased Premises at all reasonable times to make, at Landlord's cost and expense, such repairs, replacements, alterations, additions or improvements to the Leased Premises or to the Building or to any equipment located in the Building as shall be necessary or as Landlord may be required to do by contract, governmental authority or court order or decree. No such entry or repairs, replacements, alterations, additions or improvements by Landlord shall be deemed or contrued to be a disturbance of Tenant's quiet and peaceable possession of the Leased Premises or a violation of any rights of Tenant or of any covenants or other obligations of Landlord under this Lease; provided, however, Landlord will use reasonable efforts to minimize interference with Tenant's rights under Paragraph 26 hereof. Repairs, replacements, alterations, additions and improvements to the Leased Premises required to be made by any governmental authority or court order or decree, or board of fire underwriters, shall be made by Landlord, at Landlord's expense, except to the extent such expense is included in Operating Expenses. -20- 9. ADDITIONS AND ALTERATIONS A. Except for the Landlord's Work to be constructed in accordance with Exhibit B attached hereto, Tenant shall not make any alterations, improvements or additions to the Leased Premises without the prior written consent of Landlord, which consent as to nonstructural, nonmechanical or nonelectrical alterations, improvements or additions shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the preceding sentence, Landlord's consent shall not be required for nonstructural, nonmechanical and nonelectrical alterations, improvements or additions, the total, aggregate cost of which is less than $2,500. If Landlord consents to said alterations, improvements or additions, it may impose such conditions with respect thereto as Landlord deems appropriate, in its reasonable discretion, including, without limitation, requiring Tenant to furnish Landlord with security for the performance of the work and payment of all costs to be incurred in connection with such work; insurance against liabilities which may arise out of such work; plans and specifications, and all permits necessary for such work. The work necessary to make any alterations, improvements or additions to the Leased Premises other than the Landlord's Work, whether prior to or subsequent to the Commencement Date, shall be done at Tenant's expense and shall be performed by employees of Landlord or contractors hired by Landlord except to the extent Landlord gives its prior written consent to Tenant's hiring its own contractors. Landlord may condition its consent to Tenant hiring its own contractors, on Tenant delivering to Landlord, prior to commencement of such work, copies of all contracts entered into with respect thereto and all other documents and information reasonably requested by Landlord. It is understood and agreed that, in the event Landlord shall give its written consent to the making of any alterations, improvements or additions to the Leased Premises, such written consent shall not be deemed to be an agreement or consent by Landlord to subject its interest in the Property to any mechanics' or materialmen's liens which may be filed in connection therewith. Tenant shall promptly pay to Landlord or Tenant's contractors, as the case may be, when due, the cost of all such work. If Landlord or Landlord's designee performs such work, Tenant shall also pay to Landlord a percentage of the cost of such work [such percentage to be established by Landlord from time to time on a uniform basis for the Building, but such percentage shall not exceed ten percent (10%)] sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs and expenses arising from the supervision of such work by Landlord or Landlord's designee with such work promptly upon being billed for same. Upon completion of any repair, replacement, alteration, improvement or addition performed by Tenant, or its contractors and subcontractors, Tenant shall deliver to Landlord, if payment is made by Tenant directly to its contractors, evidence of payment and contractors' and subcontractors' affidavits and full and final waivers of all liens for labor, services or materials, all in form and substance satisfactory to Landlord, from each contractor, subcontractor, supplier and other person or entity that may be entitled to a lien due to such repair, replacement, alteration, improvement or addition. To the extent Landlord or a contractor engaged by Landlord does not perform the work, Tenant shall indemnify, defend and hold Landlord and the Property harmless from, and shall pay, all liabilities, claims, judgments, costs, damages, liens and expenses related -21- to any repair, replacement, alteration, addition or improvement performed by Tenant, or its contractors and subcontractors, including all reasonable attorneys' fees and legal costs, and Tenant shall require each of its contractors in each of its contracts to so defend and indemnify Landlord; provided, however, Tenant shall not indemnify, defend and hold Landlord harmless from the reasonable cost of any repairs and/or replacements which Landlord is obligated to make under Paragraph 8 hereof. All work done by Tenant or its contractors pursuant to Paragraphs 8 or 9 hereof shall be done in a first-class workmanlike manner using only the highest grades of materials, which shall be at least comparable in quality to Building Standard materials at the time of such work, and shall comply with all insurance requirements and all applicable laws, ordinances, rules, regulations and orders of all courts and other tribunals, governmental and quasi-governmental departments and agencies. Any work undertaken by Tenant shall be performed by labor which is not incompatible with the labor employed in the Building by Landlord. B. Unless Tenant notifies Landlord prior to the construction of any alteration, improvement or addition (other than Landlord's Work) that Tenant shall remove the same upon termination of this Lease and provides adequate assurance (including a reasonable amount of security) to Landlord, in Landlord's reasonable discretion, that any damage to the Leased Premises upon such removal shall be promptly repaired or restored by Tenant, at its sole cost, all alterations, improvements and additions to the Leased Premises, whether temporary or permanent in character, made or paid for by Landlord or Tenant, shall without compensation to Tenant become Landlord's property at the termination of this Lease by lapse of time or otherwise and shall, unless Landlord requests their removal (in which case Tenant shall remove the same as provided in Paragraph 17 hereof), be relinquished to Landlord in good order, repair and condition, except for ordinary wear and tear and repairs and/or replacements which Tenant is not obligated to make pursuant to this Lease. At the time Tenant requests in writing that Landlord consent to any alterations, improvements or additions, Tenant may request in writing that Landlord elect whether or not it will request their removal. if such election is so requested by Tenant, Landlord agrees to make such election in writing at the time it gives any written consent to such alterations, improvements or additions. Landlord's election with respect to any particular items shall not bind Landlord as to any other items that are not expressly covered by such election. 10. COVENANT AGAINST LIENS Tenant has no authority or power to, and shall not, cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon Landlord's and/or Tenant's title or interest in the Property or the Leased Premises. Tenant covenants and agrees not to suffer or permit any lien of mechanics or materialmen or others to be placed against the Property or the Leased Premises with respect to work or services performed or claimed to have been performed for, or materials furnished or claimed to have been furnished to, Tenant or the Leased Premises, and, in case of -22- any such lien attaching or claim thereof being asserted, Tenant covenants and agrees to immediately notify Landlord of such lien and cause it to be immediately released and removed of record. In the event that such lien is not released and removed within ten (10) days after Landlord gives Tenant a written demand for the release and removal of such lien, or within any shorter period of time (with or without any such demand) if Landlord's interest in the Property, the Building or the Leased Premises might be jeopardized if Landlord were required to wait any such ten (10) day period, Landlord, at its sole option, may take all action necessary to release and remove such lien (without any duty to investigate the validity thereof) and Tenant shall promptly upon notice, either before or after such release or removal, pay or reimburse Landlord for all sums, costs and expenses (including reasonable attorneys' fees) incurred by Landlord in connection with such lien, together with interest thereon at the Interest Rate. The preceding two sentences shall not apply to liens filed by reason of Landlord's failure to pay any sums it has contracted to pay to mechanics, materialmen or others except to the extent Tenant had agreed to pay or reimburse Landlord for such sums and has not done so. Notwithstanding the foregoing in this Paragraph 10, if Tenant is diligently contesting any such lien, as determined in the reasonable discretion of Landlord, and Tenant, at its sole cost, has obtained a bond approved by Landlord, in its reasonable discretion, that prevents the foreclosure of such lien during such contest, Landlord shall not be entitled to obtain a release or removal of such lien by any payment which is reimbursable by Tenant. Tenant shall promptly provide to Landlord all information reasonably requested by Landlord to assist Landlord in determining whether Tenant is diligently contesting any such lien and whether such bond exists. 11. INSURANCE A. WAIVER OF SUBROGATION. Each party hereby waives any and every claim for recovery from such other party for any and all insurable perils, to the extent that such loss or damage is actually recovered under insurance policies, or would have been recoverable under insurance policies, if Landlord and Tenant continuously maintained the insurance coverage required under this Paragraph 11, during the Term. Inasmuch as this mutual waiver will preclude the assignment of any such claim by subrogation or otherwise to an insurance company (or any other person), Landlord and Tenant each agrees to give written notice of the terms of this mutual waiver to each insurance company which has issued, or in the future may issue, policies of physical damage insurance to it, and to have said insurance policies properly endorsed, if necessary, to prevent the invalidation of said insurance coverage by reason of said waiver. B. TENANT'S INSURANCE. Tenant shall purchase and, during the entire Term of the Lease, maintain insurance with terms, coverages and in companies reasonably satisfactory (but in no event with a Best's Rating of less than A- or a Best's Financial Size Category of less than Class X) to Landlord. Tenant agrees to secure such reasonable increases in limits as Landlord may from time to time reasonably request. Tenant shall maintain the following coverages in the following amounts: -23- (i) Comprehensive General Liability Insurance, naming Landlord, the Building's property manager and all mortgagees as additional insureds, and covering, on an occurrence basis, claims of bodily injury, personal injury and property damage arising out of Tenant's operations, assumed liabilities or use of the Leased Premises, for limits of liability not less than: Personal and Advertising $1,000,000 each occurrence Injury Liability $2,000,000 annual aggregate Property Damage Liability $1,000,000 each occurrence $2,000,000 annual aggregate General Annual Aggregate $2,000,000 Products-Comp/OPS Aggregate $1,000,000 Umbrella Liability $15,000,000 Insured Participation 0% (ii) Property Damage Insurance covering, on an occurrence basis, (A) all additions, improvements and alterations to the Leased Premises paid for by Landlord, directly or indirectly, including, without limitation all floor coverings, wall coverings, window coverings and ceiling tile (whether or not such floor coverings, wall coverings, window coverings and ceiling tile are building standard) and all Landlord's Work that is not Base Construction as set forth in Exhibit B-1 attached hereto and (B) all office furniture, trade fixtures, office equipment, merchandise and all other items of Tenant's property in the Leased Premises. Such insurance shall be written on an "all risks" of physical loss or damage basis and will have limits sufficient to cover the full replacement cost value of the covered items and name Landlord as additional insured and all mortgagees as loss payees (as their interests may appear). If requested by the holder of any mortgage now or hereafter placed against the Property, said insurance also shall include a standard mortgage clause for the benefit of such holder. The coinsurance clause of such insurance shall be waived and a replacement cost endorsement shall be included, which endorsement provides that in the event of loss, Tenant is fully reimbursed when replacing old with new without deduction for physical depreciation. (iii) Business interruption insurance in the amount of at least $500,000, sufficient to reimburse Tenant for direct and indirect loss of earnings attributable to all perils commonly insured against by prudent tenants or attributable to prevention of, or access to the Leased Premises as a result of such perils. -24- (iv) During such time as Tenant shall be constructing or contracting for the construction of any alterations, improvements or additions in the Leased Premises, Tenant shall carry builder's risk insurance, completed value form, covering all physical loss in an amount reasonably satisfactory to Landlord, naming as additional insureds Landlord, the Building's property manager and all mortgagees. Tenant shall, prior to the commencement of the Term, furnish to Landlord certificates evidencing such coverage, which certificates shall state that such insurance coverage may not be changed or cancelled without at least thirty (30) days' prior written notice to Landlord and Tenant. Such coverage shall apply or relate solely to the Property and not be diluted by claims against Tenant related to activities not applicable or related to the Property. C. AVOID ACTION INCREASING RATES. Tenant shall comply with all applicable laws and ordinances, all orders and decrees of courts and all requirements of other governmental authorities, and shall not, directly or indirectly, make or allow to be made any use of the Leased Premises which may thereby be prohibited or be dangerous or cause injury to person or property or which may jeopardize any insurance coverage or may increase the cost of insurance or require additional insurance coverage. If by reason of the failure of Tenant to comply with the provisions of this Paragraph 11C, any insurance coverage is jeopardized or insurance premiums are increased, Landlord may exercise the option either to require Tenant to cease each activity which has jeopardized or increased the cost of the insurance coverage or make immediate payment of the increased insurance premium. If Landlord elects to require Tenant to cease each such activity Landlord shall give Tenant written notice that Tenant must cease such activity. Such notice from Landlord shall provide a cure period to Tenant of at least thirty (30) days, unless Landlord's insurance will be cancelled on a date earlier than the end of such thirty (30) day cure period if such activity has not ceased by such earlier date, in which event a shorter cure period may be given which allows Landlord a reasonable time to terminate this Lease and cause the cessation of such activity prior to such earlier date. If Tenant fails to cease each such activity within such cure period provided by Landlord, Landlord may terminate this Lease without any further notice or demand whatsoever by giving written notice of termination to Tenant and Tenant, without any further demand or notice whatsoever, shall be deemed to be automatically in default under this Lease. D. LANDLORD'S INSURANCE. Tenant acknowledges that Landlord is not obligated to carry insurance on any floor coverings, wall coverings, window coverings or ceiling tile in or about the Leased Premises or any other additions, improvements or alterations in or about the Leased Premises or on Tenant's furniture, furnishings, fixtures, equipment and/or improvements in or about the Leased Premises. Anything in this Lease to the contrary notwithstanding, Tenant agrees that Tenant shall look to the insurance policies it carries, and not to Landlord, for reimbursement for any insurable perils that affect such property. Landlord, however, during the Term of this Lease, will maintain the following insurance with a company or -25- companies having a Best's Rating of no less than A- and a Best's Financial Size Category of no less than Class X: (i) Property Damage Insurance covering, on an occurrence basis, the base Building Shell and Base Construction. Such insurance shall be written on an "all risk" of physical loss or damage basis and will have limits sufficient to cover the full replacement cost value of the covered items. The coinsurance clause of such insurance shall be waived and will include a replacement cost endorsement, which endorsement provides that in the event of loss, Landlord is fully reimbursed when replacing old with new without deduction for physical depreciation. (ii) Comprehensive General Liability Coverage in the amount of at least $1,000,000 per occurrence and $2,000,000 in the aggregate. (iii) Umbrella Liability Coverage of at least $25,000,000. Such insurance shall provide that it may not be changed or cancelled without at least thirty (30) days prior written notice to Landlord. 12. FIRE OR CASUALTY A. If less than a substantial portion (determined in accordance with Paragraph 12D below) of the Leased Premises or the Property shall be damaged by fire or other casualty, then Landlord shall repair and restore such damage with reasonable promptness, subject to delays caused by insurance adjustments and matters beyond Landlord's reasonable control and to the provisions of Paragraphs 12B and 12C below. If all or at least a substantial portion of the Leased Premises or the Property shall be damaged by fire or other casualty Landlord shall repair and restore such damage as provided herein with reasonable promptness, except when Landlord estimates that the amount of time required to obtain insurance proceeds, obtain permits and substantially complete the repair and restoration of such damage will exceed one hundred eighty (180) days from the date of the fire or other casualty, Landlord shall give Tenant written notice of such estimate within forty (40) days of the date of such fire or other casualty and thereafter, Landlord and, subject to the terms and provisions of Paragraph 12E below, Tenant shall have the right to terminate this Lease as of the date of such fire or other casualty upon giving written notice to the other party at any time within sixty (60) days after the date of such fire or other casualty. Landlord shall have no liability to Tenant, and Tenant shall not be entitled to terminate this Lease, by virtue of any delays in completion of such repair and restoration, except that if Landlord does not give Tenant such forty (40) day notice, the repair and restoration of the Leased Premises, if any, is not substantially completed by Landlord or Tenant does not have reasonable access to the Leased Premises, on or before the date that is one hundred eighty (180) days following the date of such fire or casualty and the failure of such repair and restoration to be substantially completed on or before such date is not due to matters beyond Landlord's -26- reasonable control, Tenant may terminate this Lease by giving Landlord written notice of such termination on or before the day that is one hundred ninety (190) days following the date of such fire or other casualty. If Landlord does not give Tenant such forty (40) day notice and the repair and restoration of the Leased Premises, if any, is not substantially completed by Landlord or Tenant does not have reasonable access to the Leased Premises, on or before the date that is two hundred seventy (270) days following the date of such fire or casualty for any reason whatsoever, Tenant may terminate this Lease by giving written notice to Landlord of such termination on or before the two hundred eightieth (280th) day following such fire or casualty. In addition, if Landlord does not give Tenant such forty (40) day notice and the failure of Landlord to substantially complete any repair or restoration of the Leased Premises, or provide to Tenant reasonable access to the Leased Premises by the date that is two hundred seventy (270) days following such fire or casualty is caused, in whole or in part, by matters beyond Landlord's reasonable control, Landlord shall have the option to terminate this Lease by giving written notice to Tenant of such termination on or before such two hundred eightieth (280th) day. Rent, however, shall abate on those portions of the Leased Premises as are, from time to time, untenantable and not used or occupied by Tenant as a result of such fire or other casualty , except as otherwise provided in this Paragraph 12. Notwithstanding anything herein to the contrary, Tenant shall only have the right to terminate this Lease hereunder if Tenant also terminates the Original Lease pursuant to Paragraph 12.A of the Original Lease. Any termination by Tenant of the Original Lease pursuant to Paragraph 12A thereof shall be deemed to be a termination of this Lease by Tenant pursuant to this Paragraph 12A. B. Anything in this Lease to the contrary notwithstanding, in no event shall Landlord be obligated to make any expenditure for the repair or restoration of damage caused by a fire or other casualty in excess of the sum of the insurance proceeds actually received by Landlord on account of such fire or other casualty. In addition, Landlord shall have the right to terminate this Lease in the event (a) Landlord's insurance is insufficient to pay the full cost of such repair and restoration and such fire or other casualty was caused by the negligence or wilful misconduct of Tenant, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests, (b) any mortgagee fails or refuses to make such insurance proceeds available for repair and restoration, (c) zoning or other applicable laws or regulations do not permit such repair or restoration, or (d) at least twenty percent (20%) of the rentable square feet in the Building is damaged by such fire or other casualty. In the event Landlord terminates this Lease due to the occurrence of a fire or other casualty, to the extent such fire or casualty was not caused by the negligence or wilful misconduct of Tenant and the Leased Premises were untenantable during such period and Tenant did not use occupy such untenantable portions of the Leased Premises, Tenant's Rent payable under this Lease shall be abated during the period beginning on the date of such fire or casualty and ending on the date of termination of this Lease. Notwithstanding anything to the contrary in this Lease, in the event the Leased Premises or the Property is damaged by fire or other casualty resulting from the negligence or willful misconduct of Tenant, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests, and this Lease is not terminated by Landlord, Tenant shall not be released from its -27- obligations hereunder, including, without limitation, its duty to pay Rent, which Rent shall not be abated. Except as expressly provided herein to the contrary, upon any termination of this Lease by Landlord or Tenant under this Paragraph 12 neither Landlord nor Tenant shall have any obligations to the other under this Lease, other than those obligations which survive the expiration or earlier termination of this Lease. C. Notwithstanding anything in this Lease to the contrary, Landlord shall have no duty under this Lease to repair or restore (i) any trade fixtures, furnishings, furniture, including, without limitation, equipment or personal property belonging to Tenant, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests, or (ii) any portion of the alterations, additions or improvements in the Leased Premises or the decorations thereto; provided that, subject to the other provisions in this Paragraph 12, Landlord shall be obligated to repair such alterations, additions, improvements and decorations to the extent, and only the extent, they are part of the base Building shell and the Base Construction. If, after a fire or other casualty, Tenant desires any repairs or restoration that Landlord is not obligated to perform under this Lease, and if Landlord consents thereto, the same shall be done at Tenant's sole cost and expense subject to all of the provisions of Paragraph 9 hereof Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance coverage carried by Tenant for damage to alterations, additions, improvements, decorations and other property paid for by Landlord either directly or indirectly or through an allowance to Tenant or which otherwise would become the property of Landlord at the end of the Term under the provisions of this Lease, including, without limitation, insurance proceeds relating to the Landlord's Work and floor coverings, wall coverings, window coverings and ceiling tile; provided, however, if Landlord is obligated or has elected to repair or restore the Leased Premises, Landlord shall place such insurance proceeds in escrow upon receipt thereof, and thereafter, if no default under this Lease exists and is continuing beyond any applicable notice or cure period, disburse to Tenant the insurance proceeds for the Landlord's Work, wall coverings, window coverings and ceiling tile to replace the Landlord's Work and floor coverings, wall coverings, window coverings and ceiling tile for which such proceeds were paid to Landlord in a manner mutually agreed to by Landlord and Tenant. Tenant acknowledges that Tenant shall have no right to insurance proceeds payable or paid to Landlord under any insurance Landlord maintains. D. For purposes of Paragraphs 12 and 15 hereof, damage or condemnation of a "substantial portion" of the Leased Premises or the Property shall have occurred only if, as a result of any damage, more than 50% of the rentable area of the Leased Premises is untenantable, Tenant has not used or occupied any of the untenantable portions of the Leased Premises, Tenant has used its best efforts to consolidate its offices and work space, and to take all other actions necessary for the conduct of Tenant's business, in the tenantable areas of the Leased Premises, but the conduct of Tenant's business, as it existed on the day prior to the date of such fire or other casualty, in the tenantable areas of the Leased Premises thereafter remains unfeasible, and Landlord fails to give Tenant notice, within fifty (50) days following the date of such fire or other casualty, that Landlord will provide Temporary Leased Premises (as defined in Paragraph 12E -28- below) to Tenant or if the Property or a smaller part of the Leased Premises has been damaged or condemned and Landlord determines that it is not economically prudent to repair and restore the undamaged or uncondemned part of the Property to its condition and use prior to the damage or condemnation. E. In the event the Leased Premises shall be damaged by fire or other casualty and such fire or other casualty renders all or at least a substantial portion of the Leased Premises untenantable by Tenant and Landlord estimates that the amount of time required to obtain insurance proceeds, obtain permits and substantially complete such repair and restoration will exceed one hundred eighty (180) days from the date of the fire or other casualty, and gives Tenant written notice of such estimate within forty (40) days of the date of such fire or other casualty, Landlord may substitute for the Leased Premises, or any untenantable portion of the Leased Premises which Tenant has not used or occupied, other premises in the Property (herein referred to as the "Temporary Leased Premises"); and if Tenant is already in occupancy of the Leased Premises, then in addition, Landlord shall pay the expenses of Tenant's moving to the Temporary Leased Premises and for improving the Temporary Leased Premises so that they are adequate for Tenant to conduct its business therein during the repair and restoration of such damage. Upon Tenant's request, any move by Tenant pursuant to this Paragraph 12E, shall be made during evenings, weekends or otherwise so as to incur the least inconvenience to Tenant. In the event Landlord elects to provide Temporary Leased Premises to Tenant, Landlord shall give Tenant notice of such election within fifty (50) days after the date of such fire or other casualty. If Landlord gives such notice to Tenant, Tenant shall have no right to terminate this Lease pursuant to Paragraph 12A; provided, however, if the Temporary Leased Premises are not and available for Tenant's possession on or before the date that is ninety (90) days following the date of such fire or other casualty and the failure of such Temporary Leased Premises to be so improved and available is not due to events beyond Landlord's reasonable control, Tenant may terminate this Lease by giving Landlord written notice of such termination on or before the day that is one hundred (100) days following the date of such fire or other casualty; provided, further, however, that if the Temporary Leased Premises are not available for Tenant's possession on or before the date that is one hundred fifty (150) days following the date of such fire or other casualty for any reason whatsoever, Tenant may terminate this Lease by giving Landlord written notice of such termination on or before the day that is one hundred sixty (160) days following the date of such fire or other casualty. 13. WAIVER OF CLAIMS - INDEMNIFICATION Subject to the terms and Provisions of Paragraph 8 hereof requiring Landlord to make certain repairs and/or replacements, Landlord shall not be liable to Tenant or its employees, agents, servants or other invitees or guests or to any third party for any damage either to person or property, whether resulting from the loss of use thereof or otherwise, sustained by Tenant or by other persons due in whole or in part to the Property or any part thereof or any appurtenances thereof becoming out of repair, or due to the occurrence of any act, neglect, accident or event on -29- the Property or any part thereof, including, without limitation, the Leased Premises, or due to any act or neglect of any tenant or occupant of the Property or of any other person. This provision shall apply particularly, but not exclusively, to damage caused by or from gas, electricity, snow, frost, ice, rain, steam, sewage, sewer gas or odors, fire, water or by the bursting or leaking of pipes, faucets, sprinklers, plumbing fixtures and windows, and shall apply without distinction as to the person whose act or neglect was responsible for the damage and whether the damage was due to any of the causes specifically enumerated above or to some other cause of an entirely different kind. Tenant further agrees that all personal property stored or placed upon the Leased Premises, or being delivered to or from the Leased Premises, and upon loading docks, receiving and holding areas, freight elevators, or other areas of the Property, shall be at the risk of Tenant only, and the Landlord shall not be liable for any loss or damage thereto or theft thereto. Without limitation of any other provisions hereof, Tenant agrees to defend, protect, indemnify and save harmless Landlord,, and its Affiliates, partners, and partners of such partners, officers and directors, agents and employees from and against all loss, damage or liability incurred by Tenant, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests, or by any other persons or entities, in connection with the Leased Premises and, to the extent, and only the extent, such loss, damage or liability is caused by the negligence or wilful misconduct of Tenant, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests, in any way related to the Property. Tenant also recognizes it will not be entitled to any abatement or diminution of any Rent as a result of any of the foregoing occurrences, except as otherwise expressly provided herein to the contrary, nor shall the same release Tenant from its obligations hereunder or constitute an eviction. Notwithstanding the foregoing in this Paragraph 13, Landlord agrees to defend, protect, indemnify and save harmless Tenant from and against liability incurred by Tenant and its officers, directors, Affiliates, agents and employees of Tenant) to the extent, and only the extent, the damage to person or property described in the first sentence of this Paragraph 13, or any loss, damage or theft described in the third sentence of this Paragraph 13, is caused by the negligence or wilful misconduct of Landlord, or any of its Affiliates, agents, employees, contractors, subcontractors, suppliers, invitees or guests. 14. NONWAIVER No waiver of any provision of this Lease shall be implied by any failure of either party hereto to enforce any remedy on account of the violation of such provision, even if such violation be continued or repeated subsequently, and no express waiver shall effect any provision other than the one specified in such waiver and that one only for the time and in the manner specifically stated. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Term or of Tenant's right of possession hereunder or after the giving of any notice shall reinstate, continue or extend the Term hereof or create a new tenancy or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice of the commencement of a suit for possession of the Leased Premises or after final judgment for possession of the Leased Premises Landlord may receive and collect -30- any Rent due, and the payment of said Rent shall not waive, affect or nullify said notice, suit or judgment. Neither the payment by Tenant of a lesser amount than the monthly installment of Annual Base Rent, Additional Rent or of any sums due hereunder nor any endorsement or statement on any check or letter accompanying a check for payment of Rent or other sums payable hereunder shall 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 Rent or other sums or to pursue any other remedy available to Landlord. 15. CONDEMNATION A. If the whole or any substantial portion of the Building or of the Leased Premises shall be taken in, or transferred in lieu of, condemnation or any like proceedings (all of which are sometimes referred to herein as "condemnation"), the Tenant at the option of Landlord or, subject to Landlord's rights under Paragraph 12E hereof, Tenant, shall end upon the date when the part so taken or transferred shall become vested in the condemning authority and Rent shall be apportioned as of the date of such termination. Landlord shall be entitled to receive the entire award from any condemnation without any payment to Tenant. Nothing contained herein shall prevent Tenant from pursuing a separate claim against the condemning authority of the value of furnishings, equipment and trade fixtures installed in the Leased Premises at Tenant's sole expense and for relocation expenses, provided that such claim shall in no way diminish the award or compensation payable to or recoverable by Landlord in connection with such taking or condemnation. If Landlord or Tenant does not so end the Term as a result of the taking or transfer, this Lease shall remain in effect and the Rent payable hereunder shall be equitably adjusted based on the square footage of the Leased Premises taken or transferred. Notwithstanding anything herein to the contrary, Tenant shall only have the right to terminate this Lease hereunder if Tenant also terminates the Original Lease pursuant to Paragraph 15A of the Original lease. Any termination by Tenant of the Original Lease pursuant to Paragraph 15A thereof shall be deemed to be a termination of this Lease by Tenant pursuant to this Paragraph 15A. B. Notwithstanding anything to the contrary contained herein, in the event of a condemnation of only the right to possession of all or any part of the Leased Premises for a fixed period of time or other temporary condition no longer than ninety (90) consecutive days or for the duration of an emergency no longer than ninety (90) consecutive days, then this Lease shall continue in full force and effect without any abatement of Rent, but the amounts payable by the condemning authority with respect to any period of time prior to the expiration or sooner termination of this Lease shall be paid by the condemning authority to Landlord. Landlord shall apply the amount of condemnation proceeds toward the amount of Rent or any other sums due from Tenant for the period, and Tenant shall pay to Landlord any deficiency between the amount thus paid by the condemning authority and the amount due from Tenant. Any excess of such condemnation proceeds over the amounts payable by Tenant shall be retained by Landlord. -31- 16. ASSIGNMENT AND SUBLETTING A. Tenant shall not (i) assign, sublet, convey or mortgage this Lease or any interest hereunder; (ii) permit to occur or permit to exist any assignment of this Lease, or any Hen upon Tenant's interest, voluntarily or by operation of law, (iii) subject the Leased Premises or any part thereof to any encumbrance; or (iv) permit the use or occupancy of the Leased Premises by any parties other than Tenant and its employees. The actions described under clauses (i), (ii), (iii) and (iv) in the preceding sentence are sometimes referred to below collectively as "assignment or subletting". Any such action on the part of Tenant shall constitute a breach of this Lease and such action shall automatically be deemed void and of no effect. Landlord's consent to any assignment or subletting shall not constitute a waiver of Landlord's right to withhold its consent to any future assignment or subletting. B. Except as expressly hereafter set forth below in this Paragraph 16B, no such assignment or subletting and no consent by Landlord to any assignment or subletting or election by Landlord to accept any absolute assignee or subtenant shall release Tenant or any subsequent Tenant from any covenant or obligation under this Lease and Tenant shall continue to be liable as a principal and not as a guarantor or surety, to the same! extent as if no such assignment or subletting had been made; provided, however, Landlord agrees to release Tenant from its obligations under this Lease if a permitted assignee of it has a consolidated net worth equal to or greater than Two Million Eight Hundred Fifty Thousand and No/100 Dollars ($2,850,000.00). C. If Tenant is a corporation, any transaction or series of transactions (including, without limitation, any dissolution, merger, consolidation or other reorganization of Tenant, or any issuance, sale, gift, transfer or redemption of all or a substantial portion of the capital stock of Tenant, whether voluntary, involuntary or by operation of law, any sale or transfer of all or any substantial portion of the assets of Tenant, or any combination of any of the foregoing transactions), shall be deemed to be a voluntary assignment of this Lease by Tenant subject to the provisions of Paragraphs 16A and 16B. Notwithstanding any of the foregoing in this Paragraph 16C, however, Landlord's consent shall not be required for any merger (under which the surviving corporation owns at least all of the assets of Tenant and is obligated to perform all of Tenant's obligations to Landlord under this Lease or otherwise and to any mortgagee of the Property, or any part thereof) or either of the following, provided that Landlord receives written notice thereof within thirty (30) days of the effective date thereof and all documents reasonable requested by Landlord: (a) any consolidation or reorganization of Tenant, or any sale, gift, redemption or transfer of all of the assets of Tenant, if immediately and continually thereafter all of such assets, which assets shall include, without limitation, this Lease, are owned by an entity and such entity has expressly, in a written document delivered to Landlord, or is clearly deemed by law to have, assumed all obligations (then existing and future) of Tenant under this Lease; or (b) any one (1) time consolidation or reorganization of Tenant, or any one (1) time sale, gift, redemption or transfer of substantially all of the assets of Tenant, if immediately thereafter at least substantially all of the assets of Tenant, which assets shall include, without limitation, this -32- Lease, are owned by an entity and such entity has expressly, in a written document delivered to Landlord, or is clearly deemed by law to have, assumed all obligations of Tenant under this Lease. If Tenant is a partnership, any transaction or series of transactions (including without limitation any withdrawal or admittance of a partner or any change in any partner's interest in Tenant, whether voluntary, involuntary or by operation of law, or any combination of any of the foregoing transactions) resulting in the transfer of control of Tenant, other than by reason of death, shall be deemed to be a voluntary assignment of this Lease by Tenant subject to the provisions of this Paragraph 16C. D. In the event Landlord consents to an assignment, as consideration for Landlord's consent, Tenant shall pay to Landlord as and when received by Tenant, as Additional Rent, an amount equal to 50% of the Assignment Profit (hereinafter defined). For purposes of this Paragraph 16, the term "Assignment Profit" shall mean an amount equal to all sums and other consideration, including, without limitation, any and all noncash consideration, paid or otherwise provided to Tenant by the assignee for or by reason of any such assignment (including, but not limited to, sums paid for the sale or rental of Tenant's fixtures, leasehold improvements, equipment, furniture, furnishings or other personal property, less, in the case of a sale thereof, the then net unamortized or undepreciated cost thereof, or in the case of rental thereof, less the lease cost of such items, all determined on the basis of sound accounting principles, consistently applied) less the total amount of the following, as and when paid or otherwise provided by Tenant to the assignee or independent third parties in connection with such assignment: reasonable brokerage, advertising and attorneys fees, tenant finish costs and concessions, including, without limitation, any and all non-cash consideration (such as the provision of furniture). In the event Landlord consents to a sublease, as consideration for Landlord's consent, Tenant shall pay to Landlord, as Additional Rent, an amount (the "Excess Sublease Profit") equal to 50% of the difference that results from subtracting (a) the product that results from multiplying the weighted average Sublease Profit for the Leased Premises and the Original Leased Premises on a per rentable square foot basis by 5,601 from (b) the product that results from multiplying the weighted average Sublease Profit for the Leased Premises and the Original Leased Premises on a per rentable square foot basis by the number of rentable square feet of the Leased Premises and the Original Leased Premises subleased. Such Additional Rent shall be paid to Landlord in monthly installments on the first (1st) day of each month during each period, if any, of the Term when, in the aggregate, more than 5,601 rentable square feet of the Leased Premises and/or the Original Leased Premises have been simultaneously subleased. The amount of the monthly installment payable during each such period shall be the Excess Sublease Profit during such period divided by the number of months during such period, as the amounts of such monthly installment and Excess Sublease Profit, and as such number of months during such period, shall be adjusted from time to time to reflect changes thereto resulting from new subleases and expiration and early termination of subleases. For purposes of this Paragraph 16, the term "Sublease Profit" shall mean in any year of the Term of this Lease (i) any rents, -33- additional charges and other consideration, including, without limitation, any and all non-cash consideration, paid or provided to Tenant under or in connection with any such sublease, which is in excess of the Rent accruing during such year of the Term of this Lease in respect of the subleased space, plus (ii) all sums paid for the sale or rental of Tenant's fixtures, leasehold improvements, equipment, furniture, or other personal property (less, in the case of the sale thereof, the then net unamortized or undepreciated cost thereof, or in the case of rental thereof, less the lease cost of such items, all determined on the basis of sound accounting principles, consistently applied, which net unamortized or undepreciated cost or lease cost, as the case may be, shall be deducted from the consideration paid or otherwise provided in connection with such sale in equal monthly installments over the balance of the term of the sublease, each such monthly deduction to be in amount equal to the quotient of the net unamortized or undepreciated cost or lease cost, as the case may be, divided by the number of months remaining in the term of such sublease), less, from the foregoing, the total amount of the following, as and when paid or otherwise provided by Tenant to the sublessee or independent third parties in connection with such sublease and the reasonable costs incurred by Tenant to segregate the subleased space from the Leased Premises, prorated in equal monthly amounts over the term of the sublease: the actual cost of services provided by Tenant to the sublessee or assignee (not to exceed $500 per sublease or assignment), reasonable brokerage, advertising and attorneys fees, tenant finish costs and concessions, including, without limitation, any and all non-cash consideration (such as the provision of furniture). Tenant shall furnish Landlord with a sworn statement, certified by an officer of Tenant, setting forth in detail the computation of any Assignment Profit or Sublease Profit and Excess Sublease Profit, and Landlord, or its representatives, shall have access, at all times during regular business hours to the books, records and papers of Tenant in relation thereto, and may make copies thereof. If a part of the consideration for such sublease or assignment shall be payable other than in cash, the payment of any Assignment Profit or Excess Sublease Profit to Landlord shall be payable based on the cash and the cash equivalent of all non-cash consideration. In no event shall any such sublease create or be construed to create a landlord/tenant relationship between Landlord and such sublessee. E. Tenant shall pay to Landlord upon demand by Landlord, notwithstanding that Landlord may have withheld its consent to any assignment or sublease contemplated by this Paragraph 16, an amount sufficient to reimburse Landlord for all direct costs and expenses that may be evidenced by invoice or receipt in relation to any request for Landlord's consent to an assignment or sublease (not to exceed $500 per such request), including, without limitation, reasonable attorney's fees and costs relating thereto, but excluding salaries, wages and fringe benefits of Landlord's employees, in determining whether to grant or withhold any consent contemplated by this Paragraph 16 or otherwise in connection with any assignment or subletting hereunder. -34- F. Notwithstanding anything to the contrary, it is the intention and agreement of the parties that the tenant under this Lease and the tenant under the Original Lease shall at all times be the same. The calculations under Section 16D hereof and Section 16D of the Original Lease shall aggregate both this Lease and the Original Lease to determine the amount of any Assignment Profit and Excess Sublease Profit. 17. SURRENDER OF POSSESSION Upon the expiration of the Term or upon the earlier termination of this Lease, or Tenant's tenancy or right of possession, whether by lapse of time or at the option of Landlord or Tenant as herein provided, or as otherwise provided by law, Tenant shall forthwith surrender the Leased Premises, together with all fixtures and appurtenances thereto, all in good order, condition and repair, ordinary wear and tear excepted and, with respect to the real property, also excepting any repairs and/or replacements which Tenant is not obligated to make pursuant to this Lease, and shall, subject to the term of Paragraph 9B and if Landlord so requires, restore the Leased Premises to the condition existing at the beginning of the Term, ordinary wear and tear, and repairs and/or replacements that Tenant is not obligated to make under this Lease, excepted. Any interest of Tenant in the alterations, improvements and additions to the Leased Premises made or paid for by Tenant or any person or entity other than Landlord shall, without compensation to Tenant or any such other person or entity, become Landlord's property at the termination, cancellation or expiration of this Lease by lapse of time or otherwise and such alterations, improvements and additions shall be relinquished, subject to the terms of Paragraph 9B, to Landlord at such time in good condition, ordinary wear and tear, and repairs and/or replacements that Tenant is not obligated to make under this Lease excepted. Prior to the expiration of the Term or the earlier termination of this Lease, or of Tenant's tenancy or right of possession, Tenant shall remove (a) its office furniture, trade fixtures and office equipment, and (b) all other items of property on the Leased Premises not belonging to Landlord except property leased by or through Landlord. Any property of Tenant remaining in the Leased Premises after the Term may be seized by Landlord and disposed of in any manner Landlord desires, and Tenant shall not be entitled to any such seized property or to any proceeds or other property resulting from any such disposition. 18. HOLDING OVER Tenant acknowledges that it is extremely important that Landlord have substantial advance notice of the date on which Tenant will vacate the Leased Premises, both because Landlord will require an extensive period to locate a replacement tenant and because Landlord will plan its entire leasing and renovation program for the Building in reliance on the expiration dates for leases of space in the Building. Tenant also acknowledges that if Tenant fails to surrender the Leased Premises at the expiration or termination of the Term, it will be conclusively presumed that the value to Tenant of remaining in possession, and the loss that will be suffered by Landlord as a result thereof, far exceed the amount of Annual Base Rent and -35- Additional Rent that would have been payable had the Term continued during such holdover period. Therefore, Tenant shall pay to Landlord an amount equal to the greater of (a) fair market rent for the Leased Premises, as reasonably determined by Landlord, or (b) one hundred fifty percent (150%) of the monthly installment of Annual Base Rent and one hundred fifty percent (150%) of one-twelfth (1/12) of the Additional Rent paid by Tenant during the previous calendar year. Such amount shall be paid on the first day of each month or portion thereof for which Tenant shall retain possession of the Leased Premises or any part thereof after the expiration of the Term or the earlier termination of this Lease, whether by lapse of time or otherwise. Tenant also shall pay all costs incurred and damages sustained by Landlord, whether direct or consequential, on account of such holding over. Landlord agrees to use reasonable efforts to minimize any such consequential damages, but in no event shall Landlord be obligated to expend any sum or incur any cost in connection with such efforts. The provisions of this Paragraph 18 shall not be deemed to limit or constitute a waiver or any other fights or remedies of Landlord provided herein or at law. 19. ESTOPPEL CERTIFICATE Tenant agrees that from time to time upon written request of Landlord, Tenant will deliver to Landlord within ten (10) days after Landlord's aforesaid request therefor, a statement in writing by Tenant or Tenant's duly authorized representative having knowledge of the following facts, certifying (i) that this Lease is unmodified and in full force and effect or, if there have been modifications, a description of each such modification, and that the Lease as modified is in full force and effect; (ii) the dates to which Rent and other charges have been paid; (iii) that Landlord is not in default under any provisions of this Lease, or, if in default, the nature thereof in reasonable detail; and (iv) such further matters as may be reasonably requested by Landlord, it being intended that any such statement may be relied upon by any mortgagees or prospective mortgagees, or any prospective or subsequent purchaser or transferee of all or a part of Landlord's interest in the Property. Tenant shall execute and deliver to Landlord whatever instrument may be reasonably required by Landlord for such purposes, and in the event Tenant fails so to do within such ten (10) day period after Landlord's written request therefor, Tenant, without any demand a further notice of any kind whatsoever, except for a written notice from Landlord to Tenant that Tenant shall automatically be in default under this Lease if such instrument is not executed and delivered by Tenant to Landlord within five (5) business days from the date of such notice, automatically shall be in default under this Lease. 20. MORTGAGE OR GROUND LEASE BY LANDLORD A. Tenant hereby agrees that, except as expressly provided in that certain Subordination, Non-Disturbance and Attornment Agreement (the "Subordination") dated of even date with this Lease and executed and acknowledged by Landlord, Tenant and VIB North America B.V., a Netherlands corporation, this Lease shall be subject and subordinate to (i) any mortgage that has been or may hereafter be placed upon the Property and to all amounts secured -36- thereby and (ii) to any ground lease of the Land, the Building, or both, that has been or may hereafter be entered into and to all renewals, modifications, consolidations and extensions of any of the foregoing, except to the extent that any such mortgage or ground lease provides otherwise, and in the event of a foreclosure of any such mortgage or of a conveyance in lieu thereof or of a termination of any such ground lease, at the request of the mortgagee, or purchaser at foreclosure, or the ground lessor, Tenant will attorn to the mortgagee or to the purchaser at any foreclosure sale or to the ground lessor, as the case may be; provided that Tenant's quiet enjoyment of the Leased Premises, as provided for under Paragraph 26 hereof, shall not be disturbed by such mortgagee or purchaser unless Tenant is in default hereunder. This provision is acknowledged by Tenant to be self-operative and no further instrument shall be required to effect such subordination of the Lease. However, notwithstanding the foregoing provisions of this Paragraph 20A, Tenant agrees that, upon written notice to Tenant, a mortgagee or ground lessor shall have the right at any time to subordinate any such mortgage or ground lease, respectively, to this Lease on such terms and subject to such conditions as such mortgagee or ground lessor may deem appropriate in its discretion. Upon such mortgagee or ground lessor giving Tenant the written notice referred to in the preceding sentence, the subordination of such mortgage or ground lease to this Lease shall be self-operative and no further instrument shall be required to effectuate such subordination of such mortgage or ground lease to this Lease. Tenant, within ten (10) days of Landlord's written request, shall execute, acknowledge and deliver such further instruments as any mortgagee or ground lessor may reasonably request from Tenant to evidence any subordination and attornment described in this Paragraph 20A which instrument shall not be less, and shall be as, favorable to such mortgagee or ground lessor as the Subordination is to VIB North America B.V. In the event Tenant fails to execute, acknowledge and deliver to Landlord any such instrument within such ten (10) day period, Tenant, without any demand or further notice of any kind whatsoever, except for a written notice from Landlord to Tenant that Tenant shall automatically be in default under this Lease if such instrument is not executed, acknowledged and delivered by Tenant to Landlord within five (5) business days from the date of such notice, automatically shall be in default under this Lease. B. In no event shall any mortgagee, any purchaser at a foreclosure sale or any ground lessor have any personal liability whatsoever for any warranties or representations of Landlord hereunder or in connection herewith or any liability for any security deposit or other sums deposited with Landlord or for any previous prepayment of Rent for a period greater than one (1) month unless such amounts have been delivered to such mortgagee,, purchaser or ground lessor, as the case may be. C. Provided Tenant receives written notice of the name and address of a mortgagee or ground lessor having an interest in the Property, Tenant agrees that in the event of any act or omission by Landlord hereunder which could give Tenant the right to terminate this Lease or to claim a partial or a total eviction (without implying that any such right exists), Tenant shall not exercise any such right until it has notified in writing such mortgagee or ground lessor and such -37- mortgagee or ground lessor shall have failed to commence, the curing of such act or omission within thirty (30) days of such notice and to diligently pursue the cure thereof until completed.

G. Tenant acknowledges that, although Landlord has obtained the execution and acknowledgment of the Subordination by VIB North America B.V., a current mortgagee of the Property and partner in Landlord, Landlord in no manner whatsoever represents or warrants to Tenant that any other mortgagee or ground lessor will execute and acknowledge the same agreement. Furthermore, Tenant acknowledges that the Subordination shall not necessarily be evidence of what a reasonable subordination, non-disturbance or attornment agreement would be in the event a mortgagee or ground lessor hereafter requests any such agreement. 21.

LANDLORD'S REMEDIES If Tenant shall fall to pay all or any portion of the Rent or any installment thereof when due, or shall fail to pay any other sum required to be paid by Tenant under this Lease or under the terms of any other agreement between Landlord and Tenant, or if Tenant shall violate or fail to perform any of the other covenants or conditions in this Lease which Tenant is required to observe and perform and such violation or failure to perform shall continue for thirty (30) days after written notice to Tenant or if a default shall occur under the Original Lease and shall not have been cured within any applicable cure period, or if any violation or failure of Tenant involves a hazardous condition and is not cured by Tenant immediately upon notice to Tenant, or if the interest of Tenant in this Lease shall be levied on under execution or other legal process, or if any voluntary petition in bankruptcy or for corporate reorganization or any similar relief shall be filed by Tenant or any guarantor of this Lease, or if any involuntary petition in bankruptcy shall be filed against Tenant or any such guarantor under any federal or state bankruptcy or insolvency act and shall not have been dismissed within thirty (30) days from the filing thereof, or if a receiver or person acting as a receiver shall be appointed for Tenant or any such guarantor or any of the property of Tenant or such guarantor by any court and such receiver or person acting as a receiver shall not have been dismissed within thirty (30) days from the date of his appointment, or if Tenant or any such guarantor shall make an assignment for the benefit of creditors, or if Tenant or any such guarantor shall admit in writing its inability to meet its debts as they mature, or if the Leased Premises are vacated or abandoned during the Term (unless such vacating or abandoning of the Leased Premises is limited to no more than ninety (90) days during the Term or for the purpose of subletting the Leased Premises, or a portion thereof, to an approved sublessee or assigning the Leased Premises to an approved assignee), or if Tenant breaches or defaults under the Subordination, then, subject to the terms of Paragraph 18 of Exhibit C attached hereto, Landlord may treat the occurrence of any one or more of the foregoing events as a breach of and default under this Lease, and thereupon at its option may, without notice or demand of any kind to Tenant or any other person, have any one or more of the following described remedies in addition to all other rights and remedies provided at law or in equity or elsewhere herein: A. Landlord may terminate this Lease and the Term created hereby. With or without terminating this Lease, Landlord may forthwith repossess the Leased Premises. Further, unless expressly prohibited by applicable law, if Tenant shall be in default under this Lease, Landlord shall have all self-help remedies and shall have the right upon any termination of this Lease to cease supplying services and utilities for the benefit of Tenant and the Leased Premises. If necessary, Landlord may proceed to recover possession of the Leased Premises under and by virtue of applicable laws, or by such other proceedings, including re-entry and possession, as may be applicable. If Landlord elects to terminate this Lease, everything contained in this Lease on the part of Landlord to be done and performed shall cease without prejudice, however, to the right of Landlord to recover from Tenant all rent and other sums accrued up to the time of termination or recovery of possession by Landlord, whichever is later. Whether or not this Lease -42- is terminated, at Landlord's option, any renewal or expansion fight that may be contained in this Lease shall terminate, and any consent or approval to be given by Landlord hereunder may be given or withheld in Landlord's sole and absolute discretion. B. With or without terminating this Lease, Landlord may, but shall be under no obligation to, relet part or all of the Leased Premises, for the account of Tenant, for such rent and upon such terms as shall be satisfactory to Landlord (which may include concessions, free rent and alterations of the Leased Premises) as Landlord, in its sole discretion, may determine, but Landlord shall not be liable for, nor shall Tenant's obligations hereunder be diminished by reason of, any failure by Landlord to relet the Leased Premises or any failure by Landlord to collect any rent due upon such reletting. For the purpose of such reletting, Landlord is authorized to decorate, repair (to the extent Tenant is or was obligated under this Lease to make any such repair), reasonably remodel or alter the Leased Premises at Tenant's expense. C. If Landlord shall fail to relet the Leased Premises, Tenant shall pay to Landlord as damages a sum equal to the amount of the Rent reserved in this Lease for the balance of the Term. If the Leased Premises are relet and a sufficient sum shall not be realized from such reletting after paying all of the costs and expenses of all decoration, repairs, remodeling, alterations and additions and the expenses of such reletting and of the collection of the rent accruing therefrom to satisfy the Rent provided for in this Lease, Tenant shall satisfy and pay the same to Landlord upon demand therefor from time to time. Tenant shall not be entitled to any rents received by Landlord which happen to exceed the amount of the Rent provided for in this Lease. Tenant agrees that Landlord may file suit to recover any sums falling due under the terms of this Paragraph 23 from time to time and that no suit or recovery of any portion due Landlord hereunder shall be any defense to any subsequent action brought for any amount not therefore reduced to judgment in favor of Landlord. D. At any time, with or without having relet the Leased Premises, in lieu of further damages pursuant to Paragraph 23C, Landlord may elect to recover damages from Tenant pursuant to this Paragraph 23D for the period following such election. Upon such election, Landlord shall be entitled to recover forthwith, as damages from Tenant, and Tenant shall thereupon be liable to Landlord for (in addition to any other or damages for which Tenant may be liable to Landlord), a sum of money equal to the excess, if any, of the value of the Rent provided to be paid by Tenant for the period that would have constituted the balance of the Term over the difference that results from subtracting from the fair market rental value of the Leased Premises for said period all anticipated expenses of reletting, which sum shall be immediately due and payable from Tenant to Landlord upon demand. Should the fair market rental value of the Leased Premises, or any part thereof, after subtraction therefrom of all anticipated expenses of reletting, for the balance of the Term exceed the value of the Rent provided to be paid by Tenant for the balance of the Term, upon Landlord reletting the Leased Premises, or any part thereof, Landlord shall have no obligation to pay to Tenant the excess or any part thereof or to credit such -43- excess or any part thereof against any other sums or damages for which Tenant may be liable to Landlord. E. Anything in this Lease to the contrary notwithstanding, the actual damages recoverable by Landlord for a breach of, or default under, this Lease by Tenant shall not exceed the amount which Landlord would have received if Tenant fulfilled all of its obligations under this Lease, plus all costs of Landlord in enforcing this Lease, including, without limitation, reasonable attorneys' fees, and reletting the Leased Premises, or any part thereof. Under no circumstances whatsoever shall the preceding sentence be deemed or construed to limit in any way any special, consequential or punitive damages recoverable by Landlord due to any such breach or default nor limit the other rights and remedies of Landlord provided herein and allowed at law or equity. Nothing in this Lease will be construed to give Landlord the right to possession of any of Tenant's records, files, business records or customer names or records. It is expressly understood and agreed by Landlord and Tenant that the liabilities and remedies specified in this Paragraph 23 shall survive the expiration or earlier termination of the Lease. 24. TENANT'S REMEDIES There shall be default under and breach of this Lease by Landlord if Landlord shall fail to perform or observe any term, condition, covenant, or obligation required to be performed or observed by Landlord under this Lease for a period of thirty (30) days after notice thereof from Tenant; provided, however, that if the term, condition, covenant, or obligation to perform by Landlord is of such a nature that the same cannot reasonably be performed within such 30-day period, such default shall be deemed to have been cured if Landlord commences such performance within said 30-day period and thereafter diligently undertakes to complete the same and completed the required acts within a reasonable time. Upon the occurrence of any such default, as Tenant's sole and exclusive remedy, Tenant may sue for injunctive relief or to recover damages for any loss resulting from the breach, including, without limitation, reasonable attorney's fees and reasonable court costs, but Tenant shall not be entitled to terminate this Lease or withhold or abate any rent due hereunder, except as expressly provided to the contrary in this Lease. 25. EXPENSES OF ENFORCEMENT A. If Tenant defaults in the making of any payment or in the doing of any act herein required to be made or done by Tenant, then Landlord, without any notice to Tenant (unless otherwise required by the other provisions of this Lease), may, but shall not be required to, make such payment or do such act. If Landlord elects to make such payment or do such act, all costs and expenses incurred by Landlord, plus interest thereon at the Interest Rate, from the date incurred by Landlord to the date of payment thereof by Tenant, shall constitute Additional Rent due hereunder. -44- B. If any action or proceeding is brought to enforce any term, covenant or condition of this Lease, the prevailing party in such action or proceeding shall be entitled to reasonable attorneys fees (including expenses and disbursements). 26. COVENANT OF QUIET ENJOYMENT Landlord covenants that Tenant, on paying the Rent charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, during the Term, shall peaceably and quietly have, hold and enjoy the Leased Premises subject to the terms, covenants, conditions, provisions and agreements hereof, without molestation or hindrance by Landlord or any party claiming through or under Landlord. Tenant acknowledges and agrees that all rights of Tenant to use and occupy the Leased Premises and all rights, terms and conditions of this Lease are in all respects subject to all applicable zoning and land use restrictions, and to all covenants, conditions, and restrictions or record. 27. SECURITY DEPOSIT Tenant is not required to post a security deposit with Landlord under this Lease. 28. REAL ESTATE BROKER Each party hereto represents that it has dealt with (and only with) the Brokers named in the Schedule as "Brokers" in connection with this Lease (which Brokers shall be compensated only in accordance with a written agreement between such Brokers and Landlord), and that insofar as it knows, no other broker negotiated this Lease or is entitled to any commission in connection herewith. Each party (an "Indemnifying Party") hereto agrees to indemnify, defend and hold the other party and its partners, if any, employees, agents, and officers, if any, harmless from and against all claims of any broker or finder (other than Brokers) made by, through or under such Indemnifying Party. 29.

H. INTENTIONALLY OMITTED. I. TRANSFER OF LANDLORD'S INTEREST.

Tenant further acknowledges that Landlord may assign its interest in this lease to a mortgagee as additional security and agrees that such an assignment shall not release Landlord from its obligations hereunder and the Tenant shall continue to look to Landlord for the performance of its obligation hereunder, subject to Paragraph 31 hereof. -46- J.

O. APPLICATION OF PAYMENTS.

EXHIBIT B WORK LETTER FOR LEASED PREMISES This Work Letter shall govern the design and construction of the tenant improvements agreed between Landlord and Tenant to be installed in the Leased Premises (herein referred to as the "Landlord's Work"). 1. DESIGN. A. Tenant engaged Blackburn Architects ("Tenant's Architect") to prepare the architectural plans and specifications for the Landlord's Work. The plans, specifications and drawings for the Landlord's Work (the "Final Plans") have been completed, approved by Landlord and Tenant and a set of the Final Plans have been initialed by representatives of Landlord and Tenant. The approval of the Final Plans shall not in any way be deemed to be an agreement by Landlord that the Final Plans and/or the Landlord's Work comply with any laws, ordinances, rules, regulations or requirements of any governmental authority having jurisdiction thereof or the insurance requirements of the Building insurers. B. Tenant shall not change the Final Plans. 2. COSTS. A. Landlord shall competitively bid the Landlord's Work with at least two (2) general contractors. Landlord shall enter into a construction contract for the performance of the Landlord's Work with a general contractor selected by Landlord (such firm being hereinafter referred to as the "General Contractor") provided that in Landlord's reasonable judgment, such General Contractor has submitted the most competitive bid, considering pricing and scheduling. If the proposed contract with the General Contractor contains an Above-Allowance Cost (as hereinafter defined), prior to Landlord's execution of such construction contract, Landlord shall submit to Tenant a notice setting forth the amount of such Above-Allowance Cost. Within three (3) business days following Tenant's receipt of such submission, Tenant shall notify Landlord whether it approves such Above-Allowance Cost. Within such three (3) business day period, Tenant shall have the right to meet with the General Contractor and Landlord in order to reduce the cost of the Landlord's Work by changing or emitting work set forth in the Final Plans; provided that any such changes shall not delay the date on which Landlord's Work will be Substantially Completed (as hereinafter defined). Upon the expiration of said three (3) day period, Landlord shall have the right to enter into the construction contract at a price equal to the original price less any price reduction mutually agreed to by the General Contractor and the Tenant. Landlord agrees to pay an amount (not to exceed the Tenant Allowance (as defined) for the costs of the construction of the Landlord's Work in accordance with the Final Plans approved by Landlord and Tenant. For purposes of this Exhibit B, the term "Tenant Allowance" shall mean Forty-Nine Thousand Four Hundred and Seventy-Six and XX/100 ($49,476.00) Dollars. Payments for such construction costs shall be made or credited in monthly disbursements made within a reasonable period of time after the General Contractor has submitted a disbursement request with such back-up information as Landlord shall reasonably request. All Above-Allowance Costs shall be the sole liability and responsibility of Tenant. If the Tenant Allowance exceeds the entire cost of construction of the Landlord's Work, Tenant may use the excess portion of the Tenant Allowance to pay Tenant's architectural and engineering fees. B. The term "Above-Allowance Cost" shall mean all costs and expenses in connection with the construction of the Landlord's Work (including, without limitation, all permit and approval fees and the Coordination Fee owing pursuant to Paragraph C below) in excess of the Tenant Allowance. If the construction contract for the Landlord's Work contains an Above-Allowance Cost, Tenant shall pay any such Above-Allowance Cost within ten (10) days of demand by Landlord. After the Punch List Items are completed and Tenant has accepted such completion, Landlord shall make a final determination of the total Above-Allowance Cost and deliver a reconciliation statement to Tenant, whereupon Tenant shall promptly pay Landlord any additional Above-Allowance Cost then owing to Landlord. If Tenant overpaid any such Above-Allowance Cost, Landlord shall pay such amount to Tenant when it delivers such reconciliation statement. In lieu of repaying to Tenant such saving, Landlord, at its option, may authorize Tenant in writing to deduct the amount of such saving from the succeeding Monthly Installments of Annual Base Rent coming due under the Lease (as amended hereby). C. Tenant shall pay to L.P.C. Commercial Services, Inc., as a fee ("Coordination Fee") for providing building services to the General Contractor during the course of construction of the Landlord's Work an amount equal to four (4%) percent of the cost of the Landlord's Work. The Coordination Fee shall be paid by Tenant in two (2) equal monthly installments, the first such payment becoming due upon the date of commencement of the Landlord's Work with the remaining installment being due on the first day of the following month. At Landlord's option, the Coordination Fee may be paid from and applied against the Tenant Allowance. D. All amounts payable by Tenant pursuant to this Exhibit B shall be deemed Rent for purpose of the Lease. -2- 3. COMPLETION. A. Landlord shall use its good faith efforts to cause the construction of the Landlord's Work to be Substantially Completed within sixty (60) days following the date on which the Existing Tenant shall have vacated the Leased Premises. Landlord's Work shall be "Substantially Completed" when the earlier of the following occurs: (i) Tenant's Architect determines in its reasonable professional judgment that the Landlord's Work (other than Punch List Items) is Substantially Completed or (ii) the date that Landlord's Work would have been Substantially Completed but for Tenant's Delays (as hereinafter defined) or (iii) the date on which a certificate of occupancy (including, without limitation, any temporary certificate of occupancy) or other governmental permit or approval required to permit the Leased Premises to be lawfully occupied has been obtained for the Leased Premises. Within three (3) business days of request by Landlord to Tenant, Tenant will cause Tenant's Architect to deliver a written certificate to Landlord certifying whether, in its reasonable professional judgment, the Landlord's Work has been Substantially Completed (other than Punch List Items). If Landlord notifies Tenant that it disputes the determination of Tenant's Architect regarding whether Landlord's Work has been Substantially Completed, such dispute shall be resolved by arbitration in the jurisdiction in which the Leased Premises are located in accordance with the then current Commercial Rules of the American Arbitration Association. The costs of the arbitration, including, without limitation, legal fees, shall be borne by the losing party. Notwithstanding any such arbitration, if Landlord notifies Tenant that in Landlord's good faith judgment the Landlord's Work is Substantially Completed (other than Punch List Items), then the Landlord's Work shall be deemed to be Substantially Completed, and Tenant shall occupy the Leased Premises and fulfill its other obligations hereunder (including, without limitation, the obligation to pay Rent) as if the Landlord's Work was Substantially Completed and the Commencement Date occurred on such date so determined by Landlord and this Lease shall continue in full force and effect. In the event a final non-appealable decision of the arbitrator(s) shall determine that the Commencement Date is a date later than the date established by Landlord, Landlord shall promptly reimburse Tenant the amount of any Rent paid by Tenant with respect to the period prior to the Commencement Date as determined by the arbitrator(s) together with interest thereon at the rate set forth in Section 3D(i) of this Lease. "Punch List Items" shall mean minor or insubstantial details of construction, mechanical adjustment, or decoration, the noncompletion of which does not materially interfere with Tenant's use of the Leased Premises. Provided that the performance of Landlord's Work is not interrupted or delayed, Tenant shall have access to the Leased Premises prior to the Leased Premises Commencement Date for itself and its contractors in order to perform work to prepare the Leased Premises for Tenant's occupancy. In the event the presence of Tenant's contractors causes or is likely to cause any labor difficulty or work stoppage with respect to the performance of Landlord's Work, -3- Tenant shall immediately, upon notice from Landlord, cause its contractors and materialmen to cease work and vacate the Building. B. The "Tenant Delays" are any delays in the Landlord's Work as a direct result of: (1) Tenant's failure to meet any deadline herein, or (2) Tenant's request for changes or modifications in the Final Plans; or (3) Tenant's failure to pay timely the amounts required pursuant to this Work Letter; or (4) Any inability to obtain, or delay in obtaining or installing, any improvements, fixtures, equipment materials, finishes or installations requested by Tenant or required by the Final Plans which are in excess of and/or in addition to the Building Standard; or (5) Any interference by Tenant, or any of its contractors, agents, employees or representatives with Landlord's Work being done by the General Contractor or its contractors or subcontractors; or (6) Any other action or omission by Tenant or any person acting on behalf of Tenant which is a proximate cause of any delay in the substantial completion of the Landlord's Work. 4. TENANT'S REPRESENTATIVE. Tenant hereby constitutes and appoints Liz Altizer its representative to deal with Landlord in connection with the Landlord's Work. Any notices and/or approvals given to or by said representative shall be binding upon Tenant.

FIRST EXTENSION OPTION. 1.1 (a) Tenant shall have the right to extend the Term of this Lease for an additional term of five (5) years commencing on the day following the expiration of the initial Term of this Lease (hereinafter referred to as the "Commencement Date of the First Extension Term") and ending on the day preceding the fifth anniversary of the Commencement Date of the First Extension Term (such additional term is hereinafter called the "First Extension Term") provided that: A. Tenant shall give Landlord notice (hereinafter called the "First Extension Notice") of its election to extend the term of this Lease, which notice shall be given at least eleven (11) months, but not more than twelve (12) months, prior to the expiration date of the initial Term of this Lease; and B. Tenant (i) is the Tenant, or a subsidiary, parent or Affiliate of the Tenant, originally named herein, (ii) actually occupies all of the Leased Premises initially demised under this Lease, and (iii) is not in default under this Lease or the Original Lease as of the time of the giving of the First Extension Notice and the Commencement Date of the First Extension Term and (iv) Tenant shall have exercised its right to extend the term of the Original Lease pursuant to Paragraph 1.1 of Exhibit C to the Original Lease. (b) The Annual Base Rent payable by Tenant to Landlord during the First Extension Term shall be the greater of (i) the product that results from multiplying ninety-five percent (95%) by the fair market rent for the Leased Premises or (ii) the product that results from multiplying the Annual Base Rent payable during the twelve (12) month period preceding the First Extension Term by 102%, such product to be escalated by 2% on each anniversary of the Commencement Date of the First Extension Term. Fair market rent shall be determined by Landlord, subject to the right of Tenant to arbitrate the amount of fair market rent as hereinafter provided. At least fifteen (15) months prior to the expiration of the initial Term, but in no event more than sixteen (16) months prior to the expiration of the initial Term, Tenant may give Landlord notice of its desire to determine Landlord's good faith determination of the fair market rent for the Leased Premises applicable to the First Extension Term. After Landlord receives such notice and at least fourteen (14) months prior to the expiration of the initial Term, Landlord shall give Tenant notice of such determination. The determination of fair market rent shall take into consideration fair market concessions available to a renewal tenant for comparable office space in Arlington County, Virginia. Notwithstanding anything herein to the contrary, the Annual Base Rent during the First Extension Term under this Lease and under the Original Lease shall be determined together such that the Annual Base Rent under both leases shall be the same amount on a per square foot basis. 1.2 (a) In the event Tenant gives the First Extension Notice in accordance with the provisions of Paragraph 1.1, the Annual Base Rent determined under clause (i) of Paragraph 1. I (b) is the greater than the Annual Base Rent determined under clause (ii) of Paragraph 1.1(b) and Tenant thereafter disputes the fair market rent as determined by Landlord pursuant to Paragraph 1.1(b), then at any time on or before the date occurring ten (10) business days after Tenant has been notified by Landlord of the fair market rent, Tenant may initiate the arbitration provided for herein by giving notice to that effect to Landlord, and if Tenant so initiates the arbitration such notice shall specify the name and address of the person designated to act as an arbitrator on Tenant's behalf. Within ten (10) business days after Landlord receives such notice from Tenant, Landlord shall give notice to Tenant specifying the name and address of the person designated to act as an arbitrator on its behalf.

The two arbitrators so chosen shall meet within ten (10) business days after the second arbitrator is appointed, and if, within ten (10) business days after the second arbitrator is appointed the two arbitrators do not agree upon the fair market rent, they shall together appoint a third arbitrator.

(b) Each party shall pay the fees and expenses of the original arbitrator appointed by or for such party, and all other expenses (not including the attorneys fees and similar expenses of the parties which shall be borne separately by each of the parties) of the arbitration shall be borne by the parties equally, unless a third arbitrator is selected or appointed in which event all expenses of the parties, regardless of the nature of such expenses, and the fees and expenses of the third arbitrator shall be borne by the party by or for whom the arbitrator was appointed, which arbitrator's determination of fair market rent is not selected by the third arbitrator in accordance with Paragraph 1.2(c) below. (c) If a third arbitrator is chosen as provided in Paragraph 1.2(a) above, then such third arbitrator shall select either the fair market rent determined by the arbitrator appointed -2- by or for Landlord or the fair market rent determined by the arbitrator selected by Tenant; the third arbitrator may not select any other amount, and may not "split the difference" between the determinations of the arbitrators selected or appointed by or for the parties. The third arbitrator shall so determine the fair market rent of the Leased Premises and render a written certified report of his determination to both Landlord and Tenant within ten (10) business days after appointment of the third arbitrator. (d) Each of the arbitrators selected as herein provided shall have at least ten (10) years experience in the leasing and renting of office space in first class buildings in Arlington County, Virginia.

(f) If Tenant fails to timely initiate the arbitration process or fails to timely request the appointment of an arbitrator by the American Arbitration Association (or such successor organization) or by such General District Court or other court, time being of the essence, the Landlord's determination of the fair market rent under Paragraph 1.1(b) above shall be conclusive. (g) If Tenant gives the First Extension Notice, Tenant shall be irrevocably bound to lease the Leased Premises during the First Extension Term on the terms and conditions provided in this Paragraph 1, including, without limitation, at the Annual Base Rent determined in accordance herewith. 1.3 Except as provided in this Paragraph 1, Tenant's occupancy of the Leased Premises during the First Extension Term shall be on the same terms and conditions as are in effect immediately prior to the expiration of the initial Term of this Lease, provided, however, Tenant shall have no further right to extend the Term of this Lease beyond the First Extension Term, except as expressly provided below in this Exhibit C. 1.4 If Tenant does not send the First Extension Notice pursuant to Paragraph 1.1 hereof, this Paragraph 1 and Paragraph 2 of this Exhibit C shall have no force or effect and shall be deemed deleted from this Lease. 1.5 If this Lease is renewed for the First Extension Term, then Landlord or Tenant can request the other party hereto to execute an instrument setting forth the exercise of Tenant's right -3- to so extend the initial Term of this Lease and the terms of such extension, including, without limitation, the last day of the First Extension Term. 1.6 If Tenant exercises its right to extend the Term of this Lease for the First Extension Term pursuant to this Paragraph 1 of this Exhibit C, then the word "Term", and the phrases "the Term of this Lease" or "the Term hereof", as used in this Lease, shall be construed to include, when practicable, the First Extension Term. 2.
