DEFINITIONS. (a) "Basic Cost": The actual costs incurred by the Landlord in operating and maintaining the Building and the Land during each calendar year of the Lease Term for which Landlord has not been reimbursed by insurance proceeds, condemnation awards or otherwise. Such costs shall include, by way of example rather than of limitation, (i) real property, front-foot benefit, metropolitan district and other similar taxes, including any taxes imposed on Leases or income generated thereon (exclusive of federal and state income and franchise taxes) or public or private assessments, general or special, ordinary or extraordinary, foreseen or unforeseen (other than Lease Taxes) levied against the Building or the Land; (ii) charges or fees for, and taxes on, the furnishing of electricity, water, sewer service, gas, fuel, or other utility services to the Building and the Land; (iii) costs of providing janitorial and trash removal service, restripping, resurfacing, maintaining and repairing all walkways, roadways and parking areas on the Land, security costs, and cost of maintaining grounds, common areas and mechanical systems of the Building and the Land; (iv) all other costs of maintaining and repairing any or all of the Building or Land; (v) all costs reasonably allocated by Landlord to the common areas of the Building and the Land in a multi-building development; (vi) charges or fees for any necessary governmental permits and licenses (except construction and occupancy permits for tenant's space); (vii) management fees, overhead and expenses reasonably related to management of the Building (including salaries for personnel directly responsible for management of the Building); (viii) premiums for hazard, liability, workmen's compensation or similar insurance upon any or all of the Building and the Land; (ix) costs arising under service contracts with independent contractors; and (x) the cost of any other items which, under generally accepted accounting principles consistently applied from year to year with respect to the Building or the Land, constitute operating or maintenance costs attributable to any or all of the Building or the Land.

(b) If the Landlord shall be unable to tender possession of the Premises on the anticipated occupancy date, the Landlord shall not be liable for any damage caused thereby, nor shall this Lease be void or voidable by Tenant, but in such event, unless the delay results (i) from failure of Tenant to provide plans or otherwise perform in accordance with the requirements of the Lease or (ii) from any delay in Landlord's ability to tender possession of the Premises caused by Tenant, no rental shall be payable by Tenant prior to actual tender to Tenant of possession of the Premises. (c) By occupying the Premises, Tenant shall be deemed to have accepted the same as suitable for the purpose herein intended and to have acknowledged that the Premises comply fully with Landlord's obligations, with the exception of any "punch list" type items in the Tenant Plans which may not have been completed. Landlord and Tenant, or their agents, shall meet prior to occupancy to prepare a "punch list." Prior to occupancy or within three (3) business days of delivery to Tenant by Landlord, whichever is later, Tenant agrees to execute and return to Landlord a letter prepared by Landlord confirming the Commencement Date, certifying that Tenant has accepted delivery of the Premises and that the condition of the Premises complies with Landlord's obligations hereunder, subject to any "punch list" items in the Tenant Plans which may not have been completed. -5- 6 3. BASIC RENTAL. (a) Tenant promises and agrees to pay Landlord the Basic Rental (subject to adjustment as hereinafter provided) without demand, notice, deduction, counterclaim or set-off, for each month of the entire Lease Term. The first monthly installment shall be due and payable upon execution of this Lease. The Basic Rental for each subsequent month shall be paid in advance beginning on the first day of the calendar month following the expiration of the first calendar month of the Lease Term and continuing thereafter on or before the first day of each succeeding calendar month during the term hereof; provided, however, that Basic Rental for the second calendar month shall be prorated based on one-three hundred sixty-fifth (1/365th) of the current annual Basic Rental for each day of the first partial month, if any, this Lease is in effect and shall be due and payable as aforesaid. (b) In the event any installment of the Basic Rental, or any other sums which became owing by Tenant to Landlord under the provisions hereof, are not received within seven (7) days after the due date thereof (without in any way implying Landlord's consent to such late payment), Tenant shall pay, in addition to such installment of the Basic Rental or such other sums owed, and not as a penalty, additional rental in the form of a late payment charge equal to five percent (5%) of such monthly installment of the Basic Rental or such other sums owed for each month or part thereof such payment is overdue. Notwithstanding the foregoing, the foregoing late charges shall not apply to any sums which may have been advanced by Landlord to or for the benefit of Tenant pursuant to the provisions of this Lease, it being understood that such sums shall bear interest from the date of the advance until paid in full, which Tenant hereby agrees to pay to Landlord, at the rate of eighteen percent (18%) per annum or the highest rate permitted by law, whichever is less. 4. BASIC RENTAL ESCALATION. The Basic Rental shall be increased annually, effective on each anniversary of the first full month after the Commencement Date during the term hereof, by an amount equal to three percent (3%) of the escalated Basic Rental then in effect. 5. Intentionally Deleted. 6. LANDLORD'S OBLIGATIONS. (a) Subject to the limitations hereinafter set forth, Landlord agrees, while Tenant is occupying the Premises, to furnish to Tenant; (i) facilities to provide water at those points of supply both within the Premises and those provided for general use of tenants of the Building; (ii) facilities to provide a supply of electrical current reasonably necessary for general business office use and occupancy of the Premises and electric lighting and a supply of electrical current to the common areas of the Building; (iii) heating and refrigerated air conditioning in season; and (iv) janitorial service to the Premises, all such services to be provided in scope, quality and frequency to those services being customarily provided by landlords in comparable office buildings in the surrounding area. Heating, ventilation and air conditioning requirements and standards under this Lease shall be subject, however, to such regulations as the Department of Energy or other local, state or federal governmental agency, Board or commission shall adopt from time to time. In addition, Landlord agrees to maintain the public and common areas of the Building, such as lobbies, stairs, corridors and restrooms, in reasonably good order and condition; provided, however, that Tenant shall reimburse Landlord, upon demand, for all repairs and additional maintenance resulting from damages to such public or common areas caused by Tenant, or its employees, agents or invitees. Landlord reserves the right, exercisable without notice and without liability to Tenant for damage or injury to property, persons or business and without effecting an eviction, constructive or actual, or disturbance of Tenant's use or possession of the Premises, or giving rise to any claim by Tenant for setoff or abatement of rent, to decorate and to make repairs, alterations, additions, modifications, changes or improvements, whether structural or otherwise, in and about the Building, or any part thereof, -6- 7 and for such purposes to enter upon the premises and, during the continuance of any such work, to temporarily close doors, entryways, public space and corridors in the Building and to interrupt or temporarily suspend Building services and facilities, provided access to the Premises is not materially impaired and Landlord gives Tenant notice of, and uses reasonable efforts to avoid, performance of work which will unreasonably disrupt Tenant's business operations. (b) If Landlord, to any extent, fails to make available any of the services to be provided by Landlord expressly set forth above or if any slowdown, stoppage or interruption of, or any change in the quantity, character or availability of, the services to be provided by Landlord expressly set forth above occurs, such failure or occurrence shall not render Landlord liable in any respect for damages to either person, property or business, nor be construed as an eviction of Tenant or work an abatement of rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof. Should any equipment or machinery furnished by Landlord break down or for any cause beyond Landlord's reasonable control cease to function properly, Landlord shall use reasonable diligence to repair same promptly, but Tenant shall have no claim for abatement of rent or damages on account of any interruptions in service occasioned thereby or resulting therefrom. Notwithstanding the foregoing, if Landlord negligently causes Tenant to be unable to occupy the Premises for a period of three (3) consecutive business days, the per diem Basic Rental and Basic Cost thereafter shall be abated until such time as Tenant can re-occupy the Premises. 7. IMPROVEMENT OF THE PREMISES. (a) Landlord and Tenant agree to comply with the following schedule in buildout of the Premises: (i) If a Space Plan has not as yet been prepared and approved by Landlord and Tenant, Tenant will meet with Landlord or its agents within three (3) business days after full execution of this Lease and shall provide Landlord all information reasonably necessary, to prepare a Space Plan for the Premises. Within five (5) business days after delivery by Landlord to Tenant of the Tenant's Space Plan, Tenant may accept the Space Plan as proposed or request reasonable modifications to such Space Plan. Any modifications to the Space Plan made after such period shall be made at Tenant's expense and, if delay in occupancy occurs as a result of such modifications, Tenant shall be liable to Landlord for each day beyond the projected Commencement Date that delivery of the Space Plan is delayed. (ii) Upon Tenant's acceptance of the Space Plan, either because of Tenant's approval or failure to object within the requisite five (5) business day period, Landlord shall prepare and deliver to Tenant detailed floor plan layouts, together with working drawings and written instructions sufficiently detailed to enable Landlord to let firm contracts (herein called "Tenant Plans") with respect to and reflecting the partitions and improvements in the Premises. Tenant shall fully and completely cooperate with Landlord in the preparation of the Tenant Plans, shall promptly respond to Landlord's requests for information and approvals within five (5) business days after inquiry, and shall use its best efforts to assist Landlord to complete the Tenant Plans as soon as possible. Tenant agrees to deliver to Landlord, not later than five (5) business days after delivery of the Tenant Plans to Tenant, an original executed copy of the Tenant Plans approved by Tenant; provided, however, if Tenant, in good faith, reasonably objects to any aspect of the Tenant Plans submitted by Landlord, Tenant shall specify in detail any objection to such Tenant Plans as submitted to Tenant in a written notice to Landlord within such 5-day period. Landlord shall, if applicable, modify such Tenant Plans to address Tenant's written objections, and submit new Tenant Plans to Tenant for approvals. Notwithstanding the foregoing, the Tenant Plans shall remain subject to Landlord's review and approval, which approval shall not be unreasonably withheld, and shall be deemed modified to take account of any changes reasonably required by Landlord. If Tenant fails to timely deliver the Tenant Plans as required herein or makes modifications to the Tenant Plans after the deadlines provided in this subsection, Tenant shall (1) pay to Landlord all reasonable expenses incurred by Landlord due to Tenant's modifications and/or delay in delivering the Tenant Plans; and (2) pay to Landlord as additional rent a per diem charge for each day beyond the -7- 8 initially projected Commencement Date that occupancy is delayed due to Tenant's failure to timely comply with the requirements in this Section. (iii) Time is of the essence as to all dates provided in this subsection. (b) Any changes to any approved Tenant Plans desired by Tenant shall be submitted in writing and in detail to Landlord and shall be subject to Landlord's consent, which consent shall not be unreasonably withheld. (c) Landlord shall, in a good and workmanlike manner, cause the Premises to be improved and completed in accordance with the Tenant Plans by "Landlord's Contractor" (as hereinafter defined). Landlord reserves the right however, (i) to make substitutions of material of equivalent grade and quality when and if any specified material shall not be readily and reasonably available, subject to Tenant's reasonable approval and (ii) to make changes necessitated by conditions met in the course of construction, provided that Tenant's approval of any substantial change shall first be obtained (which approval shall not be unreasonably withheld or delayed so long as there shall be general conformity with Tenant Plans. Any Special Tenant Work shall be contracted by obtaining at least three (3) contractor's competitive bids for such work; provided, however, that if Landlord's contractor incurs any additional expense because of the need to deal with the additional contractor, Tenant shall be responsible for all such expenses. (d) In the completion and preparation of the Premises in accordance with the Tenant Plans, Landlord agrees to perform at its own expense those items of work set forth on the schedules attached hereto as Exhibit C - Building Standard Materials, and Exhibit D - Tenant Space Plan (herein collectively referred to as "Standard Tenant Work"), to the extent required by Tenant Plans. All work to be performed by Landlord in addition to or in substitution for Standard Tenant Work is hereinafter referred to as "Special Tenant Work". All Special Tenant Work shall be furnished, installed and performed by Landlord, utilizing a general contractor or construction manager ("Landlord's Contractor") selected by Landlord (which may be an affiliate of Landlord or a partner in Landlord or an affiliate of a partner in Landlord) for and on behalf of Tenant and at Tenant's sole expense, based on Landlord's out-of-pocket contract or purchase price for materials, labor and service, including, without limit, any reasonable contractor's fee (not to exceed ten percent (10%)) for the contractor's overhead and profit and charges for cutting, patching, cleaning up and removal of waste and debris, plus architects' and engineers' fees, plus the product obtained by multiplying all of the foregoing, except architect's and engineer's fees (as reduced by appropriate credits for substituted Standard Tenant Work) by ten percent (10%) for Landlord's expenses and profit in handling the substitution. (e) Tenant shall pay Landlord as additional rent for all Special Tenant Work from time to time during the progress of the work, within five (5) days after Landlord shall have given Tenant an invoice or invoices therefor. All costs relating to Special Tenant Work shall be paid by Tenant to Landlord one-third (1/3) upon approval of pricing, one-third (1/3) upon commencement of construction with the balance due at the time of completion. Any failure by Tenant to pay for all Special Tenant Work shall constitute failure to pay rent when due and an Event of Default by Tenant hereunder, giving rise to all remedies available to Landlord under this Lease and at law or equity for non-payment of rent. 8. OPERATING EXPENSES. (a) During the term of this Lease, Tenant shall pay as additional rent an amount (per each square foot within the Premises) equal to the excess ("Excess") from time to time of the per square foot Basic Cost (which shall be calculated by dividing the Basic Cost by the total rentable square feet in the Building) over the Base Year Stop. Beginning with the first day of the thirteenth month of the Lease Term following the Commencement Date, and on each January 1 thereafter, Landlord shall make a good faith estimate of the Excess for each upcoming calendar year and Tenant shall pay monthly additional rent equal to one-twelfth (1/12) of such estimate. -8- 9 (b) By May 1 of each calendar year during Tenant's occupancy and the calendar year following termination of this Lease, or as soon thereafter as practical, Landlord shall furnish to Tenant a detailed statement certified as correct by a certified public accountant or officer of Landlord's managing agent of Landlord's actual Basic Cost for the previous year. If for any calendar year additional rent collected for the prior year as a result of Landlord's estimate of Basic Cost is (i) in excess of the additional rent actually due during such prior year, then Landlord shall either credit such overpayment towards Tenant's estimated share of operating expenses for the next year or refund to Tenant any overpayment, or (ii) less than the additional rent actually due during such prior year, then Tenant shall pay to Landlord, on demand, any underpayment with respect to the prior year. (c) Each statement furnished by Landlord to Tenant shall be conclusive and binding upon Tenant unless, within ninety (90) days after receipt of such statement, Tenant delivers to Landlord a written notice specifying the particular details for which such statement is claimed to be incorrect. Pending the determination of such dispute, Tenant shall pay without delay the full amount of the additional rent payable by Tenant in accordance with each such statement that Tenant is disputing. Without limiting the preceding sentence, Tenant, or its authorized agent, shall have the right, during Landlord's normal business hours and after reasonable notice, to inspect/audit, the books and records of Landlord applicable to the determination of any statement of any additional rent payable by Tenant for the purpose of verifying in good faith the information contained in such statement for a period of up to one year after the receipt of such statement by Tenant, by a certified public accountant. If the audit determines that the statement overstates the amount due by Tenant by five percent (5%) or more, (i) Landlord shall refund any overpayment revealed by Tenant's audit; (ii) Landlord shall pay the reasonable costs of the audit; provided, however, that Landlord shall have the right to dispute the findings of the audit and to obtain a reimbursement from Tenant for the costs associated thereto if it is later determined that the audit was in error to the Landlord's detriment; and (iii) Tenant shall then have the right to audit previous year's statements. (d) Should Tenant require any additional work or service, including but not limited to heating, ventilation and air conditioning ("HVAC") furnished outside Landlord's normal operating hours of 8:00 a.m. to 6:00 p.m., Monday through Friday, 9:00 a.m. to 1:00 p.m., Saturday, excluding Christmas, New Year's Day, Fourth of July, Memorial Day, Labor Day, and Thanksgiving Day, Landlord may, upon reasonable advance notice by Tenant, furnish such additional services at a charge not more than Landlord's actual cost, plus reasonable overhead for the additional services provided, it being agreed that the cost to the Landlord of such additional services shall not be considered or treated as Basic Cost. (e) Landlord may, at any time in its sole discretion, require separate metering for gas, electric power or for any other utility service required by Tenant if such service is reasonably deemed by Landlord to be in excess of Building standard usage, in which case the cost of such metering shall be at Tenant's sole cost and expense, due and payable upon demand by Landlord, and in which event Tenant shall pay for all such utility service in excess of its normal and customary usage, as metered. For any utility services that are separately metered as prescribed herein the amount of said services which had been included in the calculation of the Base Year Stop or the calculation of Basic Cost shall be excluded therefrom. (f) Notwithstanding any expiration or termination of this Lease prior to the end of the Lease Term, Tenant's obligations to pay any and all additional rent pursuant to this Lease shall continue and shall cover all periods up to the expiration or termination date of this Lease. Tenant's obligation to pay any and all additional rent or other sums owing by Tenant to Landlord under this lease shall survive any expiration or termination of this Lease. 9. USE. (a) Tenant shall use the Premises only for the Permitted Use. Tenant will not occupy or use the Premises, or permit any portion of the Premises to be occupied or used, for any business or purpose other than the Permitted Use or for any use or purpose which is unlawful, in part or in whole, disreputable -9- 10 in any manner, or extra hazardous, nor will Tenant permit anything to be done which shall in any way cause substantial noise, vibrations or fumes, or increase the rate of insurance on the Building or contents or cause any cancellation of any insurance policy covering the Building or any portion of its contents. In the event that, by reason of acts or omissions of Tenant, there shall be any increase in the rate of insurance on the Building or contents created by Tenant's acts, omissions or conduct of business, Tenant hereby agrees to pay to Landlord the amount of such increase on demand. Tenant will conduct its business and control its agents, employees and invitees in such a manner as not to create any nuisance, nor interfere with or disturb the possession of other tenants or Landlord in the management of the Building. Tenant shall not, without the prior written consent of Landlord, paint, install lighting or decorations, or install any signs, window or door lettering or advertising media of any type on or about the Premises or any part thereof. Landlord shall provide, at no cost to Tenant, Building Standard signage displaying Tenant's name at Tenant's suite entrance and one listing for Tenant on the Building directory. In accordance with the provisions of Exhibit "E", attached hereto and made a part hereof, Tenant, at its sole cost and expense, may install a sign on the exterior of the Building. The size, design, location and method of installation of said sign must be approved in advance, in writing by Landlord, and must satisfy all applicable state, county and municipal laws and regulations, with Tenant, at Tenant's expense, being responsible for securing all necessary approvals and permits. Tenant shall be responsible for all costs related to the repair of the Building's exterior if the sign is moved or relocated. (b) Notwithstanding the generality of subsection (a) above, Tenant shall conduct all activity in compliance with all federal, state, and local laws, statutes, ordinances, rules, regulations, orders and requirements of common law concerning protection of the environment or human health ("Environmental Laws"). Tenant shall also cause its subtenants (if subtenants are permitted by this Lease or are hereafter approved by Landlord), licensees, invitees, agents, contractors, subcontractors and employees to comply with all Environmental Laws.

(d) To the best of Landlord's knowledge, Landlord states that, during the period of its ownership, it has not used or deposited or consented to the use or deposit by others of Hazardous Materials on, from, or affecting the Premises in any manner which violates federal, state or local laws, ordinances, rules, or regulations governing the use, storage, treatment, transportation, manufacture, refinement, handling, production or disposal of Hazardous Materials. Landlord shall indemnify, defend (by counsel reasonably acceptable to Tenant), protect, and hold Tenant, and each of the Tenant's employees, officer, directors, shareholders, agents, successors and assigns, free and harmless from and against any and all claims, actions, causes of action, liabilities, penalties, fines, forfeitures, losses or expenses (including reasonable attorneys' fees and cost) or death of or injury to any person or damage to any property whatsoever (excluding damage to Tenant's personal property) arising from the presence of Hazardous Materials caused by Landlord and Landlord's agents, employees and contractors. (e) Tenant, its permitted subtenants, licensees, invitees, agents, contractors, subcontractors and employees shall not release, spill, pump, pour, emit, empty, dump or otherwise discharge or allow to escape Hazardous Materials onto the Land or Building, and Tenant shall take all action necessary to remedy the results of any such release, spillage, pumping, pouring, emission, emptying, dumping, discharge, or escape. (f) Tenant shall within 48 hours of receipt deliver to Landlord copies of any written communication relating to the Building or the Land between Tenant and any governmental agency or instrumentality concerning or relating to Environmental Laws. (g) Landlord agrees to provide: (1) free unreserved parking spaces to Tenant, up to the percentage set forth on the Data Sheet during the Term of the Lease; and (2) five (5) reserved visit spaces, available to all tenants in the Building, in an area determined by Landlord in its reasonable discretion, at the main entrance to the Building; it being hereby acknowledged and agreed by Tenant that Landlord shall not be responsible for enforcement thereof and that Landlord shall in no way be considered in Default of this Lease due to noncompliance of Tenant's visitor parking restriction for said spaces. Tenant, its permitted subtenants, licensees, invitees, agents, contractors, subcontractors and employees shall not use parking spaces on the Land or Building in excess of that number set out on the attached Data Sheet which has been reasonably determined by Landlord to be Tenant's proportionate share of the total parking spaces available on the Building and Land. Notwithstanding anything contained herein, if any governmental regulation or ordinance is enacted or amended after the effective date of this Lease so as to allow or require a modification in Tenant's number of parking spaces, Landlord reserves the right to make such modification without modifying in any way the rent due hereunder or any other obligations of Tenant. 10. TENANT'S REPAIRS AND ALTERATIONS. Tenant shall not in any manner deface or injure or make unapproved modifications of the Premises or the Building and will pay the cost of repairing any damage or injury done to the Premises or the Building or any part thereof by Tenant or Tenant's agents, employees or invitees. Tenant shall throughout the Lease Term take good care of the Premises and keep them free from waste and nuisance of any kind. Tenant agrees, at Tenant's sole cost and expense, to keep the Premises, including, without limitation, all fixtures installed by Tenant and any plate glass and special store fronts, in good condition and make all necessary non-structural repairs and replacements except those caused by fire, casualty or acts of God covered by Landlord's fire insurance policy covering the Building. Such repairs and replacements shall be in quality equal to the original work and installation. If Tenant fails to commence such repairs within fifteen (15) days after the occurrence of the damage or injury and complete same as soon as reasonably practicable thereafter, Landlord may, at its sole option, make such repair, and Tenant shall, -11- 12 upon demand therefor, pay Landlord for Landlord's cost thereof plus fifteen percent (15%) for overhead costs. Notwithstanding the foregoing, Landlord shall maintain and repair the roof and all structural and exterior walls of the Building, as well as the common utility system and equipment. Notwithstanding anything in the Lease to the contrary, Tenant will not make or allow to be made any alterations or physical additions in or to the Premises, including changes in locks on doors, plumbing, lighting, wiring or partitions, without the prior written consent of Landlord, which shall not be unreasonably withheld for non-structural, interior alterations and additions. All maintenance, repairs, alterations, additions or Improvements shall be conducted only by contractors or subcontractors approved in advance in writing by Landlord, which approval shall not be reasonably withheld, it being understood that Tenant shall procure and maintain, and shall cause such contractors and subcontractors engaged by or on behalf of Tenant to procure and maintain, insurance coverage against such risks, in such amounts and with such companies as Landlord may reasonably require in connection with any such maintenance, repair, alteration, addition or improvement. At the end or other termination of this Lease, Tenant shall deliver up the Premises with all improvements located therein in good repair and condition, reasonable wear and tear and casualty damage excepted, and shall deliver to Landlord all keys to the Premises. All alterations, additions or improvements (whether temporary or permanent in character) made in or upon the Premises by Landlord or Tenant shall be Landlord's property upon termination of this Lease and shall remain on the Premises without compensation to Tenant; provided, however, that if Landlord so elects at the time of consenting to same, then on or prior to the termination or upon earlier vacation of the Premises, Tenant shall remove all alterations, additions, improvements and partitions erected by Landlord or Tenant (i) after the Commencement Date and (ii) prior to the Commencement Date, if such alterations, additions or improvements exceed those which would be otherwise provided by Landlord as Standard Tenant Work and shall restore the Premises to their original condition by the date of termination of this Lease or upon earlier vacating of the Premises, except as provided herein. If Tenant fails to restore the Premises upon Landlord's request, Landlord shall have the right to perform such restoration and Tenant shall be liable for all costs and expenses incurred by Landlord therefor. 11. ASSIGNMENT AND SUBLETTING. (a) Landlord's Prior Consent Required. Neither Tenant nor Tenant's representatives, successors and assigns nor any subtenant or assignee will assign, transfer, mortgage or otherwise encumber this Lease or sublet or rent (or permit the occupancy or use of) the Premises, or any part thereof, without obtaining the prior written consent of Landlord, which consent will not be unreasonably withheld as provided in subsection (b) below, nor shall any assignment or transfer of this Lease or the right of occupancy hereunder be effectuated by operation of law or otherwise without the prior written consent of Landlord. Any reasonable expenses incurred by Landlord with respect to the review and consent or denial of consent of the foregoing shall be paid by Tenant to Landlord as additional rent, and shall be due and payable with the monthly installment of rent when billed. (b) Qualification of Subtenant. Subject to the provisions of Section 11(c) hereof, Landlord shall not unreasonably withhold its consent hereunder to any sublease by Tenant, provided that all of the following conditions are met: (i) Tenants must first notify Landlord, in writing, of any proposed sublease, at least thirty (30) days prior to the effective date of such proposed sublease. The notice to Landlord must include a copy of the proposed sublease and a copy of the proposed subtenant's financial statement for its most recent fiscal year, prepared in accordance with generally accepted accounting principles and certified by a public accountant or an executive officer of the proposed subtenant. (ii) The subtenant must have a credit rating satisfactory to Landlord (in Landlord's reasonable judgment). -12- 13 (iii) The sublease must be expressly subject and subordinate to this Lease, must require that any subtenant must comply with and abide by all of the terms of the Lease, and must provide that any termination of this Lease shall extinguish the sublease as well. (iv) The subtenant may not propose to change the use of the premises to a purpose other than as stated in Section 9 hereof, nor conduct its business in a manner which, in Landlord's reasonable judgment, is not appropriate for a first-class office building in the metropolitan Washington, D.C. area. (v) The subtenant may not be a tenant, subtenant, or other occupant of any part of the Building, unless Landlord is unable to offer such occupant comparable space elsewhere in the Building. (vi) The Tenant may not be in default under this Lease, or have committed three (3) events of monetary default hereunder during the previous twelve (12) months, whether cured or not. (vii) The sublease shall contain the following clause: "Underlying Lease Agreement. This Sublease and Subtenant's rights under this Sublease shall at all times be subject and subordinate to the underlying Lease identified in Paragraph ____ hereof, and Subtenant shall perform all obligations of Tenant under said Lease, with respect to the Sublease Premises. Subtenant acknowledges that any termination of the underlying Lease shall extinguish this Sublease. Landlord's consent to this Sublease shall not make Landlord a party to this Sublease, shall not create any privity of contract between Landlord and Subtenant or other contractual liability or duty on the part of the Landlord to the Subtenant, shall not constitute its consent or waiver of consent to any subsequent sublease or sub-sublease, and shall not in any manner increase, decrease or otherwise affect the rights and obligations of Landlord and Tenant under the underlying Lease, in respect of the Sublease Premises. Subtenant shall have no right to assign this Sublease or further sublet the Premises without the prior written consent of Landlord. Any term of this Sublease that in any way conflicts with or alters the provisions of the underlying Lease shall be of no effect as to Landlord and Landlord shall not assume any obligations as Landlord under the Sublease and Tenant shall not acquire any rights under the Sublease directly assertable against Landlord under the underlying Lease. Tenant hereby collaterally assigns to Landlord this Sublease and any and all payments due to Tenant from Subtenant as additional security for Tenant's performance of all of its covenants and obligations under the underlying Lease, and, after an Event of Default under the underlying Lease, authorizes Landlord to collect the same directly from Subtenant and otherwise administer the provisions of this Sublease, at the option of Landlord. Subtenant hereby consents to such collateral assignment of this Sublease to Landlord and agrees to observe its obligations created hereby." (c) Landlord's Right of First Refusal. Landlord shall have the right, within fourteen (14) days after receipt of the notice from Tenant, required under Section 11 (b) (i) above, that Tenant proposes to sublease all or a portion of the Premises, to elect (i) to sublet the Premises from Tenant for the term proposed by Tenant at the rent then being paid by Tenant for the Premises under Section 3 hereof (or that portion thereof which Tenant proposes to sublease) or the proposed sublease rent, whichever is higher, by a proportionate reduction in the rent as hereinafter set forth; (ii) to terminate this Lease in its entirety if Tenant intends to sublet all or substantially all of the Premises; or (iii) to require Tenant to pay Landlord, within ten (10) days of receipt, one-half (1/2) of the amount of rent payable by such sublease in excess of the amount of rent payable by Tenant hereunder with respect to the portion of the Premises sublet, offset by any direct expenses incurred by Tenant in subleasing such portion of the Premises (amortized in equal monthly payments over the initial term of such sublease). Upon exercise by Landlord of either of the -13- 14 options set forth in subsection (i) or (ii) above, Tenant shall surrender the Premises or such portion of the Premises, as the case may be, to Landlord, and thereafter the rent to be paid by Tenant pursuant to Section 3 above shall be that portion of the total rent which the amount of square foot area remaining in the possession of Tenant bears to the total square foot area of the Premises. In the event that Landlord does not exercise its right to sublet the Premises, or such portion of the Premises, as the case may be, or to terminate this Lease, within said fourteen (14) day period, Tenant shall have the right, subject to the provisions of subsection (iii) above, to sublet the Premises or a portion thereof after first obtaining the written consent of Landlord as provided in Section 11(a) above. Upon exercise by Landlord of the option set forth in subsection (iii) above, Tenant covenants and agrees to provide Landlord with semi-annual statements, prepared and verified by a certified public accountant or executive officer of Tenant, stating the amount of rent received by Tenant from its subtenant(s) during such semi-annual period. If such statement shows Tenant failed to make the full payment required by subsection (iii) above, a late charge equal to ten percent (10%) of the amount due shall be paid by Tenant to Landlord as additional rent, and shall be due and payable with the monthly installment of rent next becoming due. For purposes of calculating any amounts due from Tenant pursuant to subsection (iii) above, the "amount of rent payable by Tenant" exclusive of such amounts due pursuant to subsection (iii) shall be that portion of the total rent which the amount of square foot area sublet by Tenant bears to the total square foot area of the Premises. (d) No Waiver or Release. The consent by Landlord to any assignment or subletting shall not be construed as a waiver or release of Tenant from the terms of any covenant or obligation under this Lease, nor shall the collection or acceptance of rent from any such assignee, subtenant or occupant constitute a waiver or release of Tenant of any covenant or obligation contained in this Lease, nor shall any such assignment or subletting be construed to relieve Tenant from obtaining the consent in writing of Landlord to any further assignment or subletting. Tenant hereby assigns to Landlord the rent due from any subtenant of Tenant and hereby authorizes each such subtenant to pay said rent direct to Landlord, at Landlord's option, in the event of any Event of Default by Tenant under the terms of this Lease. (e) Subsidiary of Tenant. Tenant may assign all or part of this Lease, or sublease, all or part of the Premises, without the consent of Landlord, to any corporation or partnership that controls, is controlled by, or under common control with Tenant. 12. INDEMNITY. (a) Landlord shall not be liable for, and Tenant shall indemnify and save harmless Landlord, ground lessor, if any, and Landlord's managing agent, if any, from and against and from all fines, damages, suits, claims, demands, losses and actions (including reasonable attorneys' fees) for any injury to person (including death) or damage to or loss of property on or about the Premises caused by Tenant, its employees, contractors, subtenants, invitees or by any other person entering the Premises or the Building under the express or implied invitation of Tenant, or arising out of Tenant's use of the Premises. Landlord shall not be liable or responsible for any loss or damage to any property or death or injury to any person occasioned by theft, fire, act of God, public enemy, criminal conduct of third parties, injunction, riot, strike, insurrection, war, court order, requisition or other governmental body or authority, by other tenants of the Building or any other matter beyond the reasonable control of Landlord, or for any injury or damage or inconvenience which may arise through repair or alteration of any part of the Building, or failure to make repairs, or from any cause whatever except Landlord's and Landlord's agents', employees' or contractors' gross negligence or willful misconduct. (b) Landlord hereby agrees to make no claim against Tenant, and will indemnify and save Tenant, its agents, employees and invitees harmless from any claim which shall be made against Tenant by any agent, employee, licensee or invitee of Landlord or by others claiming the right to be on or about the common area for any injury, loss or damage to person or property occurring upon the common areas, unless due to Tenant's and Tenant's agents, employees or invitees gross negligence or willful misconduct. -14- 15 13. SUBORDINATION. This Lease and all rights of Tenant hereunder shall be and are subject and subordinate at all times to any deeds of trust, mortgages, installment sale agreements and other instruments or encumbrances, as well as to any ground leases or primary leases, that now or hereafter cover all or any part of the Building, the land or an interest of Landlord therein, and to any and all advances made on the security thereof, and to any and all increases, renewals, modifications, consolidations, replacements and extensions of any of such deeds of trust, mortgages, installment sale agreements, instruments, encumbrances or leases, as well as any substitutions therefor, all automatically and without the necessity of any further action on the part of Tenant to effectuate such subordination. Tenant shall, however, upon demand at any time or times execute, acknowledge and deliver to Landlord any and all instruments and certificates that in the reasonable judgment of Landlord may be necessary or proper to confirm or evidence such subordination. Notwithstanding the foregoing, if any mortgagee, trust beneficiary or ground lessor shall elect to have this Lease treated as if it became effective and Tenant had taken possession prior to the lien of its mortgage or deed of trust or prior to its ground lease, and shall give notice thereof to Tenant, this Lease shall be deemed to have become effective and Tenant's right to possession shall be considered prior to such mortgage, deed of trust, or prior to its ground lease whether this Lease is dated prior or subsequent to the date of said mortgage, deed of trust or ground lease or the date of recording thereof. In the event any mortgage or deed of trust to which this Lease is subordinate is foreclosed or a deed in lieu of foreclosure is given to the mortgagee or beneficiary, Tenant shall attorn to the purchaser at the foreclosure sale or to the grantee under the deed in lieu of foreclosure; in the event any ground lease to which this Lease is subordinate is terminated, Tenant shall attorn to the ground lessor. Tenant shall upon demand at any time execute, acknowledge and deliver to Landlord's mortgagee (including the beneficiary under any deed of trust) or other holder any and all instruments and certificates that in the judgment of Landlord's mortgagee may be necessary or proper to confirm or evidence such attornment. Landlord shall obtain a Non-Disturbance Agreement from the holder of each mortgage, Deed of Trust and ground lease encumbering the building, per the terms of Section 52 hereinbelow. 14. RULES AND REGULATIONS. Tenant and Tenant's agents, contractors, employees and invitees will comply fully with all requirements of the Rules and Regulations of the Building and related facilities, as specified in the Rules and Regulations now or hereafter sent by Landlord to Tenant. Landlord shall at all times have the right to change the rules and regulations to promulgate other Rules and Regulations in such manner as Landlord may deem advisable, in its reasonable discretion, for safety, care or cleanliness of the Building and related facilities or the Premises, and for preservation of good order therein, all of which Rules and Regulations, changes and amendments will be forwarded to Tenant in writing and shall be carried out and observed by Tenant. Tenant shall be responsible for compliance therewith by the agents, contractors, employees and invitees of Tenant. 15. INSPECTION. Landlord or its officers, agents and representatives, and any ground lessor or mortgagee thereof, shall have the right to enter into and upon any and all parts of the Premises at all reasonable hours upon reasonable advance notice (or, in any emergency or for the purpose of performing routine maintenance, at any hour and without advance notice) to (a) inspect the Premises at any time, (b) clean or make repairs or alterations or additions as Landlord may deem necessary (but without any obligation to do so, except as expressly provided for herein), or (c) show the Premises to prospective tenants, purchasers or lenders; and Tenant shall not be entitled to any abatement or reduction of rent by reason thereof, nor shall such be deemed to be an actual or constructive eviction. Landlord agrees to use reasonable efforts to minimize disruption of Tenant's business. -15- 16 16. CONDEMNATION. If the whole or, as determined by Landlord in its sole discretion, any substantial part of the Land or the Building should be taken for any public or quasi-public use under governmental law, ordinance or regulation, or by right of eminent domain, or by private purchase in lieu thereof and the taking would prevent or materially interfere with the use of the Premises for the purpose for which they are being used, as determined by Landlord and Tenant, this Lease shall terminate and the rent shall be abated during the unexpired portion of this Lease, effective when the physical taking of said Land or the Building shall occur. If part of the Land or Building shall be taken for any public or quasi-public use under any governmental law, ordinance or regulation, or by right of eminent domain, or by private purchase in lieu thereof, and this Lease is not terminated as provided in the sentence above, this Lease shall not terminate but the rent payable hereunder during the unexpired portion of this Lease shall be reduced to such extent as Landlord and Tenant shall determine may be fair and reasonable under all of the circumstances. In such event, Landlord, at its expense, shall restore the remaining premises to a complete architectural unit. In the event of any such taking or private purchase in lieu thereof, Landlord and Tenant shall each be entitled to all remedies provided by law; provided, however, that any award paid to Tenant shall not detract from any award which Landlord is entitled to receive; and if Landlord's award is reduced to any extent as a result of any award to Tenant, then Tenant shall assign and pay over to Landlord the amount by which Landlord's award was so reduced. 17. FIRE OR OTHER CASUALTY. In the event of damage to or destruction of the Premises or the Building, or the entrances and other common facilities necessary to provide normal access to the Premises, caused by fire or other casualty, Tenant shall provide immediate notice thereof to Landlord, and Landlord shall make repairs and restorations as hereafter expressly provided, unless this Lease shall be terminated by Landlord or Tenant or unless any mortgagee which is entitled to receive casualty insurance proceeds fails to make available to Landlord a sufficient amount of such proceeds to cover the cost of such repairs and restoration. If (i) the damage is of such nature or extent, in the judgment of Landlord's architect, that more than one hundred twenty (120) consecutive days, after the event of the damage or destruction would be required (with normal work crews and hours) to repair and restore the part of the Premises or Building which has been damaged, or (ii) a substantial portion of the Premises or the Building is so damaged that, in Landlord's sole judgment, it is uneconomic to restore or repair the Premises or the Building or the repairs to the Premises or the Building will take more than one hundred twenty (120) days to substantially complete, as the case may be, Landlord shall so advise Tenant in writing within thirty (30) days of the date of the destruction, and Landlord or Tenant, for a period of ten (10) days thereafter, shall have the right to terminate this Lease by written notice to the other, as of the date specified in such notice, which termination date shall be no later than thirty (30) days after the date of such notice. In the event of such fire or other casualty, if this Lease is not terminated pursuant to the terms of this Section 17, and if (i) sufficient casualty insurance proceeds are available for use for such restoration or repair, and (ii) this Lease is then in full force and effect, Landlord shall proceed promptly and diligently to restore the Premises to its substantially similar condition prior to the occurrence of the damage, provided that Landlord shall not be obligated to repair or restore any alterations, additions or fixtures which Tenant or any other tenant may have installed unless Tenant, in a manner satisfactory to Landlord, assures payment in full of all costs which may be incurred by Landlord in connection therewith. Landlord shall not insure any improvements or alterations to the Premises in excess of Standard Tenant Work, or any fixtures, equipment or other property of Tenant. Tenant shall, at its sole expense, insure the value of its leasehold improvements, fixtures, equipment or other property located in the Premises, for the purpose of providing funds to Landlord to repair and restore the Premises to its substantially similar condition prior to occurrence of the damage. If there be any such alteration, fixtures or additions and Tenant does not assure or agree to assure payment of the cost or restoration or repair as aforesaid, Landlord shall have the right to determine the manner in which the Premises shall be restored so as to be substantially the same as the Premises existed -16- 17 prior to the damage occurring, as if such alterations, additions or fixtures had not been made or installed. The validity and effect of this Lease shall not be impaired in any way by, and Landlord shall have no liability as a result of, the failure of Landlord to complete repairs and restoration of the Premises or of the Building within one hundred twenty (120) consecutive days after the date of damage or destruction, even if Landlord had in good faith notified Tenant that it estimated that the repair and restoration would be completed within such period, provided that Landlord proceeds diligently with such repair and restoration, except that Tenant shall have the right to terminate this lease by providing Landlord with written notice thereof within five (5) days of the expiration of said one hundred twenty (120) day period. In the case of damage to the Premises is of a nature or extent that Tenant's continued occupancy of all or any material part of the Premises is substantially impaired, the rent otherwise payable by Tenant hereunder shall be equitably abated or adjusted for the duration of such impairment. In no event, however, shall any damages be payable by Landlord to Tenant in respect of business interruption resulting from any fire or other casualty on the Premises or Building. Tenant shall be responsible to insure and/or repair all of Tenant's leasehold improvements and all equipment, fixtures and personal property located in the Premises. 18. HOLDING OVER. Tenant shall, at the termination of this Lease by lapse of time or otherwise, yield up immediate possession to Landlord. If Landlord agrees in writing that Tenant may hold over after the expiration or termination of this Lease, unless the parties hereto otherwise agree in writing on the terms of such holding over, the holdover tenancy shall be subject to termination by either Landlord or Tenant at any time upon not less than thirty (30) days advance written notice, and all of the other terms and provisions of this Lease shall be applicable during that period, except Tenant shall pay Landlord from time to time upon demand, as a rental for the period of any holdover, an amount equal to one hundred fifty percent (150%) of the Basic Rental in effect on the termination date, computed on a daily basis for each day of the holdover period. No holding over by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease except as otherwise expressly provided in this Lease. The foregoing notwithstanding, if Landlord does not agree in writing that Tenant may hold over after the expiration or termination of this Lease, Landlord, in addition to accepting the daily rental during the period of such holding over, as hereinabove provided, shall be entitled to pursue all remedies at law to which Landlord is entitled, including, without limitation, rights to ejectment and damages. 19. TAXES. Tenant shall be liable for all taxes levied or assessed against personal property, furniture or fixtures placed by Tenant in the Premises, and if any such taxes for which Tenant is liable are in any way levied or assessed against Landlord, Tenant shall pay the Landlord upon demand that part of such taxes for which Tenant is primarily liable hereunder. 20. EVENTS OF DEFAULT. The occurrence of any of the following events shall be deemed to be an event of default ("Event of Default") by Tenant under this Lease: (a) Tenant shall fail to pay when due any rental or other sums payable by Tenant hereunder (or under any other lease now or hereafter executed by Tenant in connection with space in the Building), and same is not cured within five days after Landlord's written notice thereof to Tenant, provided, however, that Landlord shall not be required to provide notice upon the third (3rd) such default by Tenant within any twelve (12) month period. -17- 18 (b) Tenant shall fail to comply with or observe Section 9 of this Lease (or a comparable section of any other lease now or hereafter executed by Tenant in connection with space in the Building). (c) Tenant shall fail to comply with or observe any other provision of this Lease (or any other lease now or hereafter executed by Tenant in connection with space in the Building), and same is not cured within fifteen (15) days after Landlord's written notice thereof to Tenant identifying the specific failure or violation, provided however, that in the event the violation identified is incapable of being cured within such fifteen (15) day period for reasons which are beyond the reasonable control of Tenant, then such fifteen (15) day cure period shall be extended for an additional reasonable amount of time necessary for Tenant to effect such cure, but in any event not longer than forty-five (45) days, as long as Tenant proceeds diligently to effect such cure upon its receipt of Landlord's written notice. (d) Tenant or any partner or guarantor of Tenant, as the case may be, shall apply for or consent to the appointment of a receiver, trustee or liquidator of itself or himself or any of its or his property, admit in writing its or his inability to pay its or his debts as they mature, make a general assignment for the benefit of creditors, be adjudicated a bankrupt, insolvent or file a voluntary petition in bankruptcy or a petition or an answer seeking reorganization or an arrangement with creditors or to take advantage of any bankruptcy, reorganization, insolvency, readjustment of debt, dissolution or liquidation law or statute, or an answer admitting the material allegations of a petition filed against it or him in any proceeding under any such law, or if action shall be taken by Tenant or any partner or guarantor of Tenant for the purposes of effecting any of the foregoing. (e) Any court of competent jurisdiction shall enter an order, judgment or decree approving a petition seeking reorganization of Tenant or all or a substantial part of the assets of Tenant or any partner or guarantor of Tenant, or appointing a receiver, sequestrator, trustee or liquidator of Tenant or any partner or guarantor of Tenant or any of its or his property, and such order, judgment or decree shall continue unstayed and in effect for any period of at least ninety (90) days. 21. REMEDIES. Upon the occurrence of any Event of Default specified in this Lease, Landlord shall have the option to pursue any one or more of the following remedies without any notice or demand whatsoever: (a) Distrain, collect or bring an action for such rent as may be in arrears, and request entry of judgment therefor as provided for in case of rent in arrears, or file a proof of claim in any bankruptcy or insolvency proceeding for such rent, or institute any other proceedings, whether similar or dissimilar to the foregoing, to enforce payment thereof. (b) Declare due and payable and sue for and recover, all unpaid rent for the unexpired period of the Lease Term (and also all additional rent as the amounts thereof can be determined or reasonably estimated) as if by the terms of this Lease the same were payable in advance, discounted to its present value at an interest rate equal to the prime rate as announced in the Wall Street Journal or if not published, another comparable publication on the date that Landlord seeks such remedy, together with all legal fees and other expenses incurred by Landlord in connection with the enforcement of any of Landlord's rights and remedies hereunder. (c) Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord; and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for trespass or any claim for damages therefor, and Tenant agrees to pay to Landlord on demand the amount of all loss and damage which Landlord may suffer by reason of such termination, -18- 19 whether through inability to relet the Premises on satisfactory terms or otherwise, including the loss of rental for the remainder of the Lease Term. (d) Without termination of the Lease, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for trespass or any claim or damages therefor; and relet the Premises on behalf of the Tenant on such terms as Landlord shall deem advisable and receive the rent therefor, and Tenant agrees to pay to Landlord on demand any deficiency that may arise by reason of such reletting for the remainder of the Lease Term. (e) Without termination of the Lease, enter upon the Premises, by force of law, without being liable for trespass or any claim for damages therefor, and do whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand for any expenses which Landlord may incur in thus effecting compliance with Tenant's obligations under this Lease, and Tenant further agrees that Landlord shall not be liable for any damages resulting to the Tenant from such action. (f) If Tenant fails to perform any covenant or observe any condition to be performed or observed by Tenant hereunder or acts in violation of any covenant or condition hereof beyond any applicable cure or grace period set forth in this Lease, Landlord may, but shall not be required to on behalf of Tenant, perform such covenant and/or take such steps, including entering upon the Premises, as may be necessary or appropriate, if Landlord shall have given Tenant at least three (3) days prior written notice of Landlord's intention to do so, unless an emergency situation exists, in which case Landlord shall have the right to proceed immediately and all costs and expenses incurred by Landlord in so doing, including reasonable legal fees, shall be paid by Tenant to Landlord upon demand, plus interest at the overdue interest rate set forth herein from the date of expenditure(s) by Landlord, as additional rent. Landlord's proceeding under the rights reserved to Landlord under this Section shall not in any way prejudice or waive any rights Landlord might otherwise have against Tenant by reason of Tenant's default. (g) Exercise any other rights and remedies available to Landlord at law or in equity. No reentry or taking possession of the Premises by Landlord shall be construed as an election on its part to terminate this Lease, unless a written notice of such intention be given to Tenant. Neither pursuit of any of the foregoing remedies provided nor any other remedies provided herein or by law shall constitute a forfeiture or waiver of any rent due to Landlord hereunder or of any damages accruing to Landlord by reason of the violation of any of the terms, provisions and covenants herein contained. Landlord's acceptance of rent following an Event of Default hereunder shall not be construed as Landlord's waiver of such Event of Default. No waiver by Landlord of any violation or breach of any of the terms, provisions and covenants herein contained shall be deemed or construed to constitute a waiver of any other violation or Event of Default. The loss or damage that Landlord may suffer by reason of termination of this Lease or the deficiency from any reletting as provided for above shall include the expense of repossession and any repairs or remodeling undertaken by Landlord following possession. Should Landlord at any time terminate this Lease for any default, Tenant shall not be relieved of its liabilities and obligations hereunder and, in addition to any other remedy Landlord may have, Landlord may recover from Tenant all damages Landlord may incur by reason of such default, including the cost of recovering the Premises and the loss of rental for the remainder of the Lease Term. Tenant's obligations and liabilities under this Lease shall also survive repossession and reletting of the Premises by Landlord pursuant to the foregoing provisions of this Section 21. (h) The abatement of Basic Rental, if any, and other concessions of the Landlord (which may include among other items: (i) brokerage fees; (ii) moving allowances; (iii) Tenant improvements; (iv) Lease assumptions; (v) unamortized portions of the buildout; and (vi) any other cash allowances or payments) are subject to the condition that, throughout the Lease Term, Tenant will perform and comply with all of the terms, covenants and conditions of this Lease to be performed or complied with by Tenant. If, after the occurrence of an Event of Default, Landlord terminates this Lease or re-enters and takes -19- 20 possession of the Premises without such a termination, the abatement of Basic Rental and other Landlord concessions shall cease to apply and Tenant shall be obligated within 10 days after demand, to pay to Landlord the unamortized portion of the Basic Rental abated and the value of all Landlord's concessions, said amounts to be amortized on a straight-line basis over the initial lease term.

Time is of the essence for the provisions of this Section 47. (c) If Tenant elects to exercise its right of first option, Landlord and Tenant shall promptly enter into a modification of this lease which will bring such space under the terms and conditions of this Lease, except that the rental rate for the additional space shall be the then current escalated rental rate being -26- 27 paid by Tenant.

Additionally, Tenant's right of first (1st) refusal shall be in effect upon the subsequent termination of said third (3rd) party Tenant's lease for said space. Time is of the essence for the provisions of this Section 49.

(e) (i) Within ten (10) days of the date of Tenant's exercise of its option to lease the Additional Space, or as soon thereafter as reasonably possible but in no event longer than thirty (30) days with both parties hereto agreeing to negotiate in good faith with time being of the essence, Landlord and Tenant shall execute an addendum to this Lease to set forth (a) the number of Rentable Square Feet of space constituting the Demised Premises after the addition of the Additional Space; (b) the location of the Additional Space by amending Exhibit A-1 of this Lease; (c) the amount of the Monthly Basic Rent for the Demised Premises as increased by the Additional Space; (d) the adjustments to the percentages for determining additional rent; and (e) the schedule for the construction of the improvements in the Additional Space.
