THIS LEASE AGREEMENT (this "Lease") is made and entered into this 30th day of April, 2002, by and between (i) COMSTOCK PARTNERS, L.C., a Virginia limited liability company (hereinafter referred to as "Landlord"), and (ii) Comstock Homes, Inc. (hereinafter referred to as "Tenant"), and referred to by singular pronouns of the neuter gender, regardless of the number and gender of the parties involved.

WITNESSETH: Upon and subject to the terms of this Lease, Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Leased Premises (as defined below), for the Term (as defined below), except that Landlord reserves and Tenant shall have no right in and to (a) the use of the exterior faces of all perimeter walls and windows of the Building, (b) the use of the roof of the Building, or (c) the use of the air space above the Building, except as specifically set forth herein.

1. DEFINITIONS

(a) General Interpretive Principles. For purposes of this Lease, except as otherwise expressly provided or unless the context otherwise requires, (i) the terms defined in this Section have the meanings assigned to them in this Section and include the plural as well as the singular, and the use of any gender shall be deemed to include all other genders; (ii) accounting terms not otherwise defined herein have the meanings assigned to them in accordance with generally accepted accounting principles; (iii) references herein to "Sections," "subsections," "paragraphs," and other subdivisions without reference to a document are to designated Sections, subsections, paragraphs, and other subdivisions of this Lease; (iv) a reference to a subsection without further reference to a Section is a reference to such subsection as contained in the same Section in which the reference appears, and this rule shall also apply to paragraphs and other subdivisions; (v) the words "herein," "hereof," "hereunder," and other words of similar import refer to this Lease as a whole and not to any particular provisions; (vi) the word "including" means "including, but not limited to"; (vii) daily rent is calculated on a thirty (30) day month applied to the number of days being charged, (viii) all amounts due Landlord hereunder are in United States dollars; and (ix) the words "months" and "years" mean calendar months and calendar years..

(b) Special Lease Definitions. As used in this Lease the following words and phrases shall have the meanings indicated:

Advance Rent: Sixteen Thousand, Three Hundred and Sixty Eight and 88/100 ($16,368.88) representing the Basic Rent for the first full month of the Term after the Lease Commencement Date, which Tenant shall pay to Landlord upon execution of this Lease. Landlord acknowledges receipt of the Advance Rent subject to collection.

Basic Rent: For each Lease Year, an amount equal to the product obtained by multiplying the Rentable Area of the Leased Premises leased by Landlord to Tenant during such Lease Year by the Rent per Square Foot for such Lease Year. The Basic Rent shall increase each year by 2.6% over the immediately prior year's Basic Rent. Therefore the Basic Rent for the second year is determined by multiplying the Basic Rent for the first year by 102.6% and for each subsequent year by multiplying the Basic Rent for the immediately prior year's Basic Rent by 102.6%.

Accordingly, the Basic Rent during the Initial Term hereunder will be as follows:

The Landlord or the Project General Contractor shall keep Tenant informed as to the status of construction so as to provide Tenant advance notice of the anticipated date of Substantial Completion.

Leased Premises: The area located on the fifth (5^th) floor of the Building which is outlined in black on the floor plan, attached hereto as Exhibit A and incorporated herein, and containing the following amount of Rentable Area:

The Tenant shall provide Landlord evidence that it has incurred rent expenses at the Existing Office Space for any month where Tenant does not collect sub-lease rental payments equal to the amount due from Tenant for that month for the Existing Office Space as requested by Landlord and Landlord shall provide a credit towards the amount due hereunder from Tenant for the same month. However, the amount of Rent Offset shall not exceed Fifty Thousand Dollars ($50,000.00) in the aggregate. In the event the amount of Rent Offset granted by Landlord does not exceed Twenty-Five Thousand Dollars ($25,000.00) during the first year of the Term, the Landlord agrees that the escalation of the Basic Rent as provided for herein shall, rather then commencing with the beginning of the second year of the term, shall not commence until the beginning of the third (3^rd) year of the Term and in such event the schedule of basic Rent set forth in paragraph l(b) shall be amended to reflect the change in the amount due as Basic Rent hereunder.

Rentable Area: The total rentable area of the Leased Premises, which (although greater than the actual usable area) is agreed to be approximately 7,703 square feet, which shall be verified by the project architect upon completion of the Tenant Improvement Plans and in the event the final calculation is different then as aforesaid the project architect shall provide a written statement to the parties hereto as to the total Rentable Square Feet of the Premises and said written statement shall be attached as an amendment hereto modifying the portions of this Agreement as is appropriate without modifying the general terms hereof.

Security Deposit: Upon execution of this Lease, in addition to paying Landlord the Advance Rent set forth herein, Tenant shall deliver and pay to Landlord a Security Deposit as set forth in Paragraph 19 hereof.

Storage Space: During the term hereof and provided Tenant occupies at least 5,000 square feet within the Building and provided Tenant has not been in default beyond any applicable cure period, the Landlord shall provide Tenant, at no additional cost, with access and exclusive use of a portion of the penthouse of the Building for storage of personal property of Tenant. All costs of constructing and maintaining the storage area shall be borne by Tenant.

Term: Subject to Tenant's exercise of its Option to Renew this Lease, as provided for herein, the period commencing on the Lease Commencement Date and ending on the last day of the calendar month which completes SEVEN (7) YEARS after the Lease Commencement Date, but in any event the Term shall end on any date when this Lease is sooner terminated as provided for herein.

Operating Expenses shall also be reduced as provided in Section 3(b).

Notwithstanding anything in this Lease to the contrary, for purposes of the calculations to be made pursuant to this paragraph.

If during the Term (including the Base Year) the Building is less than ninety-five percent (95%) occupied, or if by reason of partial operation of the Building all Operating Expenses for a calendar year have not been incurred, variable Operating Expenses shall be adjusted for that calendar year to an amount which the Landlord estimates, in the Landlord's reasonable judgment using generally accepted accounting principals, would have been incurred had the Building been ninety-five percent (95%) occupied and in full operation during that calendar year in accordance with generally accepted accounting principles consistently applied. Any adjustment to reflect ninety-five percent (95%) occupancy shall not affect costs or expenses that do not vary with occupancy (such as insurance premiums, utility and maintenance costs for Common Areas, and other fixed expenses) and shall be made in a manner that reasonably reflects all factors relating to the impact of occupancy on the amount of variable costs and expenses and that reasonably constitutes the most accurate possible approximation of what such variable costs and expenses would actually have been had the Building actually been ninety-five percent (95%) occupied and fully assessed for taxes, and shall not result in any adjustment of Operating Expenses to a level such that if all occupied areas of the Building had paid all of such adjusted Operating Expenses, Landlord would have received more than actual Operating Expenses without such adjustment to ninety-five percent (95%) occupancy.

In the event that pursuant to the terms of this Lease, Tenant is obligated to pay its proportionate share of Operating Expenses, Tenant shall have the right to audit Landlord's books and records as follows:

A.: Tenant shall be entitled at any reasonable time during business hours, after giving at least five (5) days prior written notice, to inspect Landlord's books and records relating to Tenant's proportionate share of Operating Expenses at the site of the location of such books and records and to obtain an audit thereof by an independent auditor selected by Tenant (and reasonably acceptable to Landlord) to determine the accuracy of such amounts billed to Tenant by Landlord for the last two (2) calendar years immediately preceding the calendar year in which such notice is given.

B.: If such audit discloses a liability for Tenant's proportionate share of Operating Expenses which is less then the amount billed to, and paid by, Tenant, then Landlord shall within thirty (30) days refund to Tenant all amounts paid by Tenant in excess of the amount Tenant is actually required to pay as provided for herein ("Refund Amount").
C.: All costs of such audit shall be paid by Tenant. However, in the event the Refund Amount is greater then five percent (5%) of the amount for which Tenant is actually liable (as disclosed by the audit), all reasonable actual costs of such audit shall be paid by Landlord.

Notwithstanding anything to the contrary set forth herein, or elsewhere provided for, in no event shall Tenant's Proportionate Share of annual increases in Real Estate Taxes and Operating Expenses above the Calendar 2003 Base Year exceed one dollar ($1.00) per square foot of space covered by this Agreement during any one calendar year. In the event the square footage changes during any calendar year the average monthly square footage shall be used.

Option to Renew: Tenant is hereby given the option to renew this Lease for two (2) periods of three (3) years, or one (1) period of either; three (3) years, five (5) years, or seven (7) years, provided that there shall be no Event of Default under any of the terms of this Lease either at the time of the giving of any such notice or at the time of commencement of any renewal. Tenant shall give notice in writing to the Landlord of its exercise of such option at least six (6) months prior to the termination of the Initial Term. Such renewal shall be based on the same terms, covenants and conditions as are contained in this Lease except that the Basic Rent for the first year of the renewal period shall be at the then current market rate (for comparable buildings in the general vicinity of the Building), as agreed to by the parties hereto. In the event the parties can not agree to the current market rate as set forth above then the Landlord and Tenant shall each select a licensed commercial real estate broker doing business in Northern Virginia (the "Selected Brokers"), whereupon the Selected Brokers shall select a third similarly qualified broker, who shall each then provide to the parties their expert opinion as to the then current market rate and the average of the three opinions shall be the current market rate for the purposes of this paragraph. In establishing the Basic Rent for the renewal term, the parties or the brokers who determine the Basic Rent shall consider and take into account Tenant's continuing obligation to pay Additional Charges for Operating Expense Increases over the Operating Expense Base, unless the parties have agreed in writing that Tenant's obligation to pay Additional Charges for Operating Expense Increases over the Operating Expense Base shall be terminated and the Operating Expense Base shall be re-set to be the sum of the actual Operating Expenses during the year in which such renewal term commences. Notwithstanding the foregoing, in no event shall the Basic Rent for the first year of the renewal period be less then the current rate at the end of the Initial Term. In the event the Tenant elects to renew, the Landlord shall provide a one time allowance for the re-painting and re-carpeting of the space with specifications matching the original installations which can be utilized at any one renewal term commencement.

Person: A natural person, a partnership, a limited liability company, a corporation, and any other form of business or legal association or entity.

Project General Contractor: Signet Construction Company, Inc. of Fairfax, Virginia.

Real Estate Taxes: All taxes, assessments, vault rentals, water and sewer rents, if any, and other charges, if any, general, special, or otherwise, including all assessments for schools, public betterment, and general or local improvements, which are mandatory or legally compelled, levied or assessed upon or with respect to the ownership of and/or all other taxable interests in the Building and the land on which it is built imposed by any public or quasi-public authority (including The Reston Association and any related or similar organization having jurisdiction over

the Building and the ability to assess fees to the owner of the Building whether now existing or created after the date hereof) having jurisdiction and personal property taxes levied or assessed on Landlord's personal property used in connection with the operation, maintenance, and repair of the Building. Except for taxes, fees, charges, and impositions described in the next succeeding sentence, Real Estate Taxes shall not include any inheritance, estate, succession, transfer, gift, franchise, corporation, income, or profit tax or capital levy. If at any time during the Term the methods of taxation shall be altered so that in addition to or in lieu of or as a substitute for the whole or any part of any Real Estate Taxes levied, assessed or imposed there shall be levied, assessed or imposed (i) a tax, license fee, excise or other charge on the rents received by Landlord, or (ii) any other type of tax or other imposition in lieu of, or as a substitute for, or in addition to, the whole or any portion of any Real Estate Taxes, then the same shall be included as Real Estate Taxes. A tax bill or true copy thereof, together with any explanatory or detailed statement of the area or property covered thereby, submitted by Landlord to Tenant shall be conclusive evidence of the amount of taxes assessed or levied, as well as of the items taxed. If any real property tax or assessment levied against the land, buildings or improvements covered thereby or the rents reserved therefrom, shall be evidenced by improvement or other bonds, or in other form, which may be paid in annual installments, only the amount paid or payable in any Lease Year shall be included as Real Estate Taxes for that Lease Year.

Substantially Completed: The completion of the construction or installation, or both, of the Tenant's Improvements, except for any special order, trade specific, or long-lead time items, to the extent that (i) all required governmental inspections for such Tenant Improvements have been successfully completed and only minor items remain unfinished (except for any special order, trade specific, or long-lead time items), and (ii) such minor items do not prevent Tenant from occupying the Leased Premises as reasonably determined by the project architect or the Project General Contractor. Notwithstanding anything contained herein to the contrary, or elsewhere provided, it is specifically understood and agreed that any delay caused by the any special order, trade specific, or long-lead time items of the Tenant (either supply, delivery, condition upon delivery, non-compliance of such equipment with the Construction Documents, or defects inherent to such equipment that effect the use of such equipment upon installation) shall not in any way delay the date of Substantial Completion or the date of Lease Commencement even if such delay prevents the issuance of an occupancy permit for the Leased Premises.

Taking: A taking of property or any interest therein or right appurtenant or accruing thereto, by condemnation or eminent domain or by action, proceedings, or agreement in lieu thereof, pursuant to governmental authority.

Tenant: The tenant named herein and any permitted assignee under Section 15.

If any check is mailed by Tenant. Tenant shall post such check in sufficient time prior to the date when payment is due so that such check will be received by Landlord on or before the date when payment is due.

Tenant's obligations under this subsection to pay Operating Expense Increases and Landlord's obligation to reimburse Tenant for an overpayment of Operating Expenses shall survive the expiration of the Term. If any part of the Building is leased to tenants (hereinafter referred to as "Special Tenants") which, in accordance with the terms of their leases, provide their own cleaning and janitorial services, electrical services, or are not required to pay Operating Expense Increases on the basis of operating expenses for the Building which include substantially the same components as the Operating Expenses (as defined in this Lease), the following provisions shall apply as to those components of Operating Expenses: (i) the Building Rentable Area shall be reduced by the rentable area of the space leased to Special Tenants; (ii) Tenant's Proportionate Share shall be the percentage which the Rentable Area is of the Building Rentable Area (determined after the reduction specified in clause (i); and (iii) those components of Operating Expenses shall be reduced by the sum of the amounts payable to Landlord by Special Tenants, in accordance with the terms of their leases, as reimbursements for Real Estate Taxes and expenses of owning, operating, managing and maintaining the Building and the amount of the applicable operating expense base under such Special Tenants' leases.

If Tenant fails to make any payment of Basic Rent or Additional Charges within five (5) calendar days of the due date thereof, interest shall, at Landlord's option, accrue on the unpaid portion thereof from the due date at the Default Interest Rate, but in no event at a rate higher than the maximum rate allowed by law, and shall be payable on demand.

(d) Accord and Satisfaction. No payment by Tenant, receipt or acceptance by Landlord of any lesser amount than the amount stipulated to be paid hereunder shall be deemed other than on account of the earliest stipulated Basic Rent or Additional Charges; nor shall any endorsement or statement on any check or letter be deemed an accord and satisfaction, and Landlord may accept any check or payment without prejudice to Landlord's right to recover the balance due or to pursue any other remedy available to Landlord.

However, except as otherwise provided in this Lease, Tenant shall not have any right to install air-conditioning equipment, elevators, escalators, conveyors, or mechanical systems. In addition to the foregoing, all damage or injury to the Leased Premises and to its fixtures, appurtenances and equipment or to the Building or to its fixtures, appurtenances and equipment caused by Tenant moving property in or out of the Building or by installation or removal of furniture, fixtures, or other property by Tenant shall be repaired, restored, or replaced promptly by Tenant, at its sole cost and expense, to the reasonable satisfaction of Landlord. All such aforesaid repairs, restoration, and replacements shall be in quality and class equal to the original work or installation but in no event need exceed Building standards.

8. RULES AND REGULATIONS

Tenant shall comply with, and shall cause its agents, employees and invitees to, comply with and observe all reasonable rules and regulations concerning the use, management, operation, safety, and good order of the Leased Premises, the Building and the Building parking areas which may from time to time be promulgated by Landlord, provided that such rules and regulations are not inconsistent with the provisions of this Lease and do not materially interfere with Tenant's permitted use of the Leased

Premises. Initial rules and regulations, which shall be effective until amended by Landlord, are attached to this Lease as Exhibit F hereto and incorporated herein. Tenant shall be deemed to have received notice of any amendment to the rules and regulations when a copy of such amendment has been delivered to Tenant at the Leased Premises or has been mailed to Tenant in the manner prescribed for the giving of notices. Landlord shall not be responsible to Tenant for any violation of the rules and regulations, or the covenants or agreements contained in any other lease, by any other tenant of the Building, or such tenant's agents, employees or invitees, and Landlord may waive in writing, or otherwise, any or all of the rules or regulations in respect of any one or more tenants. Landlord shall make reasonable efforts to uniformly enforce all rules and regulations.

9. TENANT'S ALTERATIONS AND INSTALLATIONS

(a) Alterations: Tenant shall not make or perform, or permit the making or performance of, any alterations, installations, improvements, additions or other physical changes in or about the Leased Premises (referred to collectively as "Alterations") without Landlord's prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. All plans, specifications and details for such Alterations, and all contractors performing the Alterations are subject to the prior written approval of Landlord, not to be unreasonably withheld, conditioned or delayed. In the event Landlord grants such consent and permits Tenant to contract out such work, such Alterations shall be made and performed in conformity with and subject to the following provisions: (i) all Alterations shall be made and performed at Tenant's sole cost and expense and at such time and in such manner as Landlord may reasonably from time to time designate; (ii) all Alterations shall be performed by adequately insured contractors approved by Landlord and in a good and workmanlike manner in accordance with all applicable Legal Requirements, and Tenant shall indemnify and hold harmless Landlord from and against any and all costs, expenses, claims, liens and damages to person or property resulting from the making of any such alterations, decorations, additions or improvements in or to the Leased Premises or the Building; (iii) no Alteration shall affect any part of the Building other than the Leased Premises or adversely affect any service required to be furnished by Landlord to Tenant or to any other tenant or occupant of the Building; (iv) all business machines and mechanical equipment shall be placed and maintained by Tenant in settings sufficient in Landlord's reasonable judgment to absorb and prevent vibration, noise and annoyance to other tenants or occupants of the Building; (v) Tenant shall submit to Landlord reasonably detailed written plans and specifications for each proposed alteration and shall not commence any such Alteration without first obtaining Landlord's written approval of such plans and specifications; (vi) all Alterations in or to the electrical facilities in or serving the Leased Premises shall be subject to the provisions of Section 5 relating to exceeding electrical capacity; (vii) notwithstanding Landlord's approval of plans and specifications for any Alteration, all Alterations shall be made and performed in full compliance with all Legal Requirements and in accordance with the Rules and Regulations; and (viii) all materials and equipment to be incorporated in the Leased Premises as a result of all Alterations shall be of good quality. If building or other permits from governmental authorities are required for any Alterations, Tenant shall obtain such permits and deliver copies thereof to Landlord before work on such Alterations is begun. After any Alterations are completed, Tenant shall cause all required governmental inspections of the Alterations to be made and shall deliver to Landlord a copy of the inspection report and one complete set of the "as built" plans for such Alterations.

(b) Unauthorized Alterations: If Tenant shall be in default under this Section by reason of the making of any Alteration not hereby authorized or by reason of failure to give any notice or to obtain any approval required herein, Tenant may cure such default within the applicable grace period provided in this Lease for curing such default by removing such Alteration and restoring the Leased Premises to their former condition, as provided in Section 7, and if Tenant fails to do so Landlord may correct or remove the same and Tenant shall be liable for any and all costs and expenses incurred by Landlord in such removal.

(c) Installed Fixtures: Except to the extent specifically provided in sub-section (d), all appurtenances, fixtures, improvements, additions and other property attached to or installed in the Leased Premises, whether by Landlord or Tenant or others, and whether at Landlord's expense, or Tenant's expense, or the joint expense of Landlord and Tenant, which are affixed to walls, floors or ceilings or which cannot be removed without structural damage to the Building, shall be and remain the property of Landlord. Any replacements of any property of Landlord, whether made at Tenant's expense or otherwise, shall be and remain the property of Landlord except as agreed to in writing by Landlord prior to Lease Execution or prior to commencing such Alterations.

(d) Tenant's Special Installations: All furniture, furnishings and trade specific equipment or fixtures, excepting lighting fixtures and equipment, but including, without limitation, business machines and equipment, vaults, vault doors and door frames, and vault equipment, if any, safe deposit equipment, counterscreens, grillwork, cages, partitions which are moveable, railings, raised floors, equipment relating to food preparation, food storage and serving, dish washing and cleaning devices and any moveable property, installed by or at the expense of Tenant shall remain the property of Tenant and are referred to herein as "Tenant's Special Installations". Tenant may at its expense remove all or any part of said property at any time during the Term, and shall at its expense remove all of said property at the expiration or other termination of the Term unless Landlord shall otherwise consent in writing. Upon removal of any or all of said property Tenant shall then repair all damage. Any of Tenant's Special Installations which are not removed from the Leased Premises at the expiration of the Term shall be deemed to have been abandoned by Tenant and may be disposed of by Landlord without liability to Tenant. Tenant shall at all times be responsible for any damage caused by the delivery, installation or operation of tenant's Special Installations.

(e) Mechanic's Liens: Notice is hereby given that Landlord shall not be liable for any labor or materials furnished or to be furnished to Tenant upon credit, and that no mechanic's, materialman's or other lien for any such labor or materials shall attach to or affect the reversion or other estate or interest of Landlord in and to the Leased Premises or the Building. Whenever and as often as any mechanic's lien or materialman's lien shall have been filed against the Leased Premises or the Building based upon any act or interest of Tenant or of anyone claiming through Tenant, or if any lien or security interest with respect thereto shall have been filed affecting any materials, machinery or fixtures used in the construction, repair or operation thereof or annexed thereto by Tenant or its successors in interest, Tenant shall forthwith take such action by bonding, deposit or payment as will remove or satisfy the lien or other security interest and in default thereof after the expiration of thirty (30) days after notice to Tenant, Landlord, in addition to any other remedy under this Lease, may pay the amount secured by such lien or security interest or discharge the same by deposit and the amount so paid or deposited shall be collectible as additional rent. The provisions of this subsection shall not be applicable to liens filed with respect to work done for Tenant's account by Landlord.

10. NAME OF BUILDING; TENANT'S SIGNS

(a) Building Name: The name of the Building shall be determined by Landlord in its sole discretion. Landlord expressly reserves the right to have the Building designated by a street number or numbers and to affix to the Building, at locations designated by Landlord, signs indicating any such number or numbers and to change the name of the Building as selected from time to time by Landlord.

(b) Roof Rights: Landlord hereby grants to Tenant the right to erect communication devices on a potion of the roof, not to exceed Tenant's Proportionate Share of the roof area that is adequate for placement of such devices. Landlord does not grant Tenant any other rights in or to the roof or the outer side of the outside walls or windows of the Building, control of which is hereby reserved by Landlord except that Tenant shall have non-exclusive access to and the use of the building roof for the installation and maintenance of communications equipment of Tenant as aforesaid. Landlord will

require detailed specifications for review and approval to be provided to Landlord and it's chosen consultant at least thirty (30) days prior to the date Tenant desires installation to commence. Any reasonable cost of landlord's consultant in connection with review and approval of the subject specifications and plans shall be reimbursed by Tenant promptly upon request therefore. All roof access will be coordinated with Landlord's management. Any building penetration shall be subject to the approval of Landlord (and its consultant's) in Landlord's sole and absolute discretion. Tenant will obtain all required permits and comply with all applicable restrictions at its sole cost and shall be solely responsible for all costs associated with installation, maintenance and removal of Tenant's roof top equipment and of any associated building penetrations.

(c) Signage: Tenant shall not display or erect any lettering, signs, advertisements, awnings or other projections on the exterior of the Leased Premises or in the interior of the Leased Premises if visible from a public way, except for Building Standard hallway door lettering or interior suite signage visible to the public way that is approved in writing in advance by Landlord (Landlord hereby approves Tenants identification sign to be located in the lobby of the Leased Premises identifying the "Comstock Companies"), Landlord shall provide a directory tablet in the main lobbies of the Building, at its expense, upon which Landlord, at Landlord's expense, will affix Tenant's name and a reasonable number of names of its affiliates, officers, partners or employees. Landlord, at Landlord's expense, shall provide a reasonable number of building standard suite identification signs. Directory listings and suite signage for any sub-tenants of Tenant shall be at Tenant's expense. The size, color, and style of such directory and names affixed thereto shall be selected by Landlord. During the term hereof and provided Tenant occupies at least 5,000 square feet within the Building, the Landlord shall provide a listing of Tenant's name on any building monument sign incorporated into the project by Landlord and shall allow Tenant to place upon the exterior walls of the Building an exterior sign subject to all restrictions created by any exterior sign rights granted to any other Tenant whose lease pre-dates this Agreement, and shall restrict exterior signage of other Tenants from being on any face of the Building where Tenant's signage is placed as permitted hereunder. The Tenant shall not utilize more then its pro-rata share of exterior signage square feet as provided for in local zoning ordinances. The Tenant shall be solely responsible for obtaining all required permits and approvals and shall be solely responsible for all costs associated with permitting, installation, maintenance, removal, and building restoration resulting from the removal of Tenant's exterior sign. Landlord will require detailed specifications for review and approval, and installation will be coordinated with Landlord's management. Any building penetration shall be subject to the approval of Landlord (and its consultant's) in Landlord's sole and absolute discretion.

11. LIABILITY INSURANCE

(a) General Liability Insurance: Tenant, at Tenant's sole cost and expense, shall obtain and maintain in effect at all times during the Term, a policy of comprehensive general public liability insurance with broad form property damage endorsement, naming Landlord and (at Landlord's request) any Mortgagee of the Building and any management agent as additional insured(s), protecting Landlord, Tenant and any such Mortgagee and management agent against any liability for bodily injury, death or property damage occurring upon, in or about any part of the Building or the land on which it is built, the Leased Premises or any appurtenances thereto, with such policies to afford protection to the limit of not less than One Million Dollars ($1,000,000.00) with respect to bodily injury, death, or property damage per occurrence with an aggregate limit of not less than Three Million Dollars ($3,000,000.00) and with a deductible of no greater than Two Thousand Five Hundred Dollars ($2,500.00) per occurrence. Such comprehensive liability insurance may be effected by a policy or policies of blanket insurance which cover other property in addition to the Leased Premises, provided that the protection afforded thereunder shall be no less than that which would have been afforded under a separate policy or policies relating only to the Leased Premises and provided further that in all other respects any such policy shall comply with the other provisions of this Section.

(b) Policy Restrictions: The insurance policy required to be obtained by Tenant under this Section: (i) shall be issued by an insurance company of recognized responsibility licensed to do business in the jurisdiction in which the Building is located; and (ii) shall be written as primary policy coverage and not contributing with or in excess of any coverage which Landlord may carry. Neither the issuance of any insurance policy required under this Lease, nor the minimum limits specified herein with respect to Tenant's insurance coverage, shall be deemed to limit or restrict in any way Tenant's liability arising under or out of this Lease. With respect to each insurance policy required to be obtained by Tenant under this Section, on or before the Lease Commencement Date, and at least thirty (30) days before the expiration of the expiring policy or certificate previously furnished, Tenant shall deliver to Landlord a certificate of insurance therefor, together with evidence of payment of all applicable premiums. Each insurance policy required to be carried hereunder by or on behalf of Tenant shall provide (and any certificate evidencing the existence of each such insurance policy shall certify) that such insurance policy shall not be cancelled unless Landlord shall have received thirty (30) days' prior written notice of cancellation.

(c) Hold Harmless: Except for the willful or negligent acts or omissions of Landlord or its agents or employees, Tenant hereby agrees to indemnify and hold harmless Landlord from and against any and all claims, losses, actions, damages, liabilities, and expenses (including reasonable attorneys' fees) that (i) arise from or are in connection with Tenant's possession, use, occupancy, management, repair, maintenance, or control of the Leased Premises, or any portion thereof, or (ii) arise from or are in connection with any willful or negligent act or omission of Tenant or Tenant's agents, employees, invitees, or subtenants, or (iii) result from any default, breach, violation, or nonperformance of this Lease or any provisions therein by Tenant, or (iv) arise from injury or death to persons or damage to property sustained on or about the Leased Premises. Tenant shall, at its own cost and expense, defend any and all actions, suits, and proceedings which may be brought against Landlord with respect to the foregoing or in which Landlord may be impleaded. Tenant shall pay, satisfy, and discharge any and all money judgments which may be recovered against Landlord in connection with the foregoing. Landlord hereby agrees to indemnify Tenant from and against any and all claims, actions, and expenses (including reasonable attorneys' fees) that arise as a direct result of Landlord's Gross Negligence and Landlord shall pay, satisfy, and discharge any and all money judgments which may be recovered against Tenant in connection with the Gross Negligence of Landlord.

12. FIRE INSURANCE

(a) Landlord shall, throughout the Term, at its expense, keep the Building, but not Tenant's Special Installations or Tenant's furniture, furnishings, trade fixtures or property removable by Tenant under the provisions of this Lease, insured against all loss or damage by fire with extended coverage in such amount as any first Mortgagee of the Building may from time to time require, but not less then the Building's full replacement cost. Tenant shall, throughout the Term, at its expense, keep Tenant's Special Installations and Tenant's personal property insured against all loss or damage by fire with extended coverage in an amount sufficient to prevent Tenant from becoming a co-insurer. Tenant's policies of insurance shall contain an appropriate clause or endorsement under which the insurer agrees that such policy shall not be cancelled without at least thirty (30) days' notice to Landlord.

(b) Landlord and Tenant will (i) if requested, advise the other as to the provisions of fire and extended coverage insurance policies obtained pursuant to this Section, and (ii) notify the other promptly of any change in the terms of any such policy which would affect such provisions.

13. DAMAGE BY FIRE OR OTHER CASUALTY

In the event of loss of, or damage to, the Leased Premises or the Building by fire or other casualty, the rights and obligations of the parties hereto shall be as follows:

(a) If the Leased Premises or any part thereof shall be damaged by fire or other casualty. Tenant shall give prompt notice thereof to Landlord, and Landlord, upon receiving such notice, shall proceed promptly and with reasonable diligence, subject to Unavoidable Delays and a reasonable time for adjustment of insurance losses, to repair, or cause to be repaired, such damage in a manner designed to minimize interference with Tenant's occupancy (but with no obligation to employ labor at overtime or other premium pay rates). If the Leased Premises or any part thereof shall be rendered untenantable by reason of such damage, whether to the Leased Premises or the Building, the Basic Rent and Additional Charges shall proportionately abate for the period from the date of such damage to the date when such damage shall have been repaired for the portion of the Leased Premises rendered untenantable. However, if, prior to the date when all of such damage shall have been repaired, any part of the Leased Premises so damaged shall be rendered tenantable and shall be used or occupied by Tenant, then the amount by which the Basic Rent and Additional Charges shall abate shall be equitably apportioned for the period from the date of any such use.

(b) If as a result of fire or other casualty more than one-half (¹/2) of the Building Rentable Area is rendered untenantable, Landlord within sixty (60) days from the date of such fire or casualty may terminate this Lease by notice to Tenant, specifying a date, not less than twenty (20) nor more than forty (40) days after the giving of such notice, on which the Term shall expire as fully and completely as if such date were the date herein originally fixed for the expiration of the Term, provided, however, Landlord terminates all similarly Tenants within the Building. If the Leased Premises are damaged as a result of fire or other casualty and if the damage to the Leased Premises (but not including Tenant's Special Installations or Alterations) is so extensive that such damage cannot be substantially repaired within one hundred and eighty (180) days from the date of the fire or other casualty (except for Unavoidable Delays), either Landlord or Tenant within thirty (30) days from the date of such fire or other casualty may terminate this Lease by notice to the other, specifying a date, not less than twenty (20) nor more than forty (40) days after the giving of such notice, on which the Term shall expire as fully and completely as if such date were the date originally fixed for the expiration of the Term. If either Landlord or Tenant terminates this Lease, the Basic Rent and Additional Charges shall be apportioned as of the date of such fire or other casualty. If neither Landlord nor Tenant so elects to terminate this Lease, then Landlord shall proceed to repair the damage to the Building and the damage to the Leased Premises (but not Tenant's Special Installations or Alterations), if any shall have occurred, and the Basic Rent and Additional Charges shall meanwhile be apportioned and abated all as provided in subsection (a). However, if such damage is not repaired and the Leased Premises and the Building restored to reasonably the same condition as they were prior to such damage within two hundred and seventy (270) days from the date of such damage (such 270-day period to be extended by the period of any Unavoidable Delays plus a reasonable time for adjustment of insurance losses), Tenant, within thirty (30) days from the expiration of such 270-day period (as the same may be extended), may terminate this Lease by notice to Landlord, specifying a date not more than sixty (60) days after the giving of such notice on which the Term shall expire as fully and completely as if such date were the date herein originally fixed for the expiration of the Term.

(c) If the Leased Premises shall be rendered untenantable to the extent of eighty percent (80%) or more by fire or other casualty during the last six (6) months of the Term, Landlord or Tenant may terminate this Lease upon notice to the other party given within ninety (90) days after such fire or other casualty specifying a day, not less than twenty (20) days nor more than forty (40) days after the giving of such notice, on which the Term shall expire as fully and completely as

if such date were the date originally fixed for the expiration of the Term. If either Landlord or Tenant terminates this Lease pursuant to this subsection, the Basic Rent and Additional Charges shall be apportioned as of the date of such fire or casualty.

(d) Landlord shall not be required to repair or replace any of Tenant's Special Installations or Alterations or any other personal property of Tenant and no damages, compensation, or claim shall be payable by Landlord for inconvenience, loss of business, or annoyance arising from any repair or restoration of any portion of the Leased Premises or of the Building, but the foregoing shall not be deemed to relieve Landlord of liability for its breach of any covenant of this Lease.

(e) The provisions of this Section shall be considered an express agreement governing any instance of damage or destruction of the Building or the Leased Premises by fire or other casualty, and any law now or hereafter in force providing for such a contingency in the absence of express agreement shall have no application.

(f) Notwithstanding any other provisions of this Lease, Landlord shall not be liable or responsible for, and Tenant hereby releases Landlord and its partners, shareholders, officers, directors, agents, and employees from, any and all liability or responsibility to Tenant or any Person claiming by, through or under Tenant, unless caused by Landlord's gross negligence, by way of subrogation or otherwise, for any injury, loss, or damage to Tenant's property covered or required to be covered by a valid and collectible fire insurance policy with extended coverage endorsement. Tenant shall require its insurer(s) to include in all of Tenant's insurance policies which could give rise to a right of subrogation against Landlord a clause or endorsement whereby the insurer(s) shall waive any rights of subrogation against Landlord, and Tenant shall pay any additional premium required therefor.

(g) Notwithstanding any other provision of this Lease, Tenant shall not be liable or responsible for, and Landlord hereby releases Tenant and its partners, shareholders, officers, directors, agents, and employees from, any and all liability or responsibility to Landlord or any Person claiming by, through or under Landlord, unless caused by Tenant's gross negligence, by way of subrogation or otherwise, for any injury, loss, or damage to Landlord's property covered or required to be covered by a valid and collectible fire insurance policy with extended coverage endorsement. Landlord shall require its insurer(s) to include in all of Landlord's insurance policies which could give rise to a right of subrogation against Tenant a clause or endorsement whereby the insurer(s) shall waive any rights of subrogation against Tenant, and Landlord shall pay any additional premium required therefor.

(h) The proceeds payable under all fire and other hazard insurance policies maintained by Landlord on the Building shall belong to and be the property of Landlord, and Tenant shall not have any interest in such proceeds. Tenant agrees to look to its own fire and hazard insurance policies in the event of damage to Tenant's Special Installations or Alterations or its personal property.

14. CONDEMNATION

(a) In the event of a Taking of the whole of the Leased Premises, this Lease shall terminate as of the date of such Taking. If only a part of the Leased Premises shall be so taken then, except as otherwise provided in this subsection, this Lease shall continue in force and effect but, from and after the date of the Taking, the Basic Rent and Additional Charges shall be equitably reduced on the basis of the portion of the Leased Premises so taken. If a part of the Building shall be taken, and if either (i) the part of the Building so taken contains more than twenty-five percent (25%) of the Rentable Area of the Leased Premises immediately prior to such Taking, or (ii) in Landlord's reasonable opinion it shall be impracticable to continue to operate the Building, then Landlord, at Landlord's option, may give to Tenant within sixty (60) days after the date upon which Landlord shall have received notice of

the Taking, thirty (30) days notice of termination of this Lease provided, however, Landlord terminates all similarly Tenants within the Building. If a part of the Building so taken contains more than twenty-five percent (25%) of the Rentable Area of the Leased Premises immediately prior to such Taking, or (ii) by reason of such Taking, Tenant no longer has reasonable means of access to the Leased Premises, then Tenant, at Tenant's option, may give to Landlord within sixty (60) days after the date upon which Tenant shall have received notice of such Taking, thirty (30) days notice of termination of this Lease. If thirty (30) days notice of termination is given by Landlord or Tenant, this Lease shall terminate upon the expiration of the thirty (30) day period. If this Lease is terminated pursuant to the foregoing provisions of this subsection, then, to the extent permitted by applicable law and such Taking, Tenant shall have access to the Leased Premises in order to remove Tenant's Special Installations and any other personal property then owned by Tenant and which Tenant is entitled to remove pursuant to this Lease during the period of thirty (30) days from the date Tenant is permitted access therefor. If a Taking occurs which does not result in the termination of this Lease, Landlord shall repair, alter, and restore the remaining portions of the Leased Premises to their former condition to the extent that the same may be feasible.

(b) Landlord shall have the exclusive light to receive any and all awards made for damages to the Leased Premises and the Building accruing by reason of a Taking or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby releases and assigns to Landlord all of Tenant's rights to such awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request, hereby irrevocably designating and appointing Landlord as its attorney-in-fact to execute and deliver in Tenant's name and behalf all such further assignments thereof. However, Tenant shall have the right to make its own claim against the condemning authority for a separate award for the value of any of Tenant's Special Installations and Alterations, for moving and relocation expenses and for such business damages and/or consequential damages as may be allowed by law which do not constitute part of the compensation for the Building and do not diminish the amount of the award to which Landlord would otherwise be entitled.

(c) If the Leased Premises or any portion thereof is rendered untenantable due to a Taking or if Tenant is prevented from accessing the Leased Premises due to a Taking and this Lease is not terminated, then the Basic Rent and any additional rent reserved herein shall be abated in proportion to the untenantable area of the Premises for the duration of such Taking.

15. ASSIGNMENT AND SUBLETTING

Tenant shall not mortgage, pledge, encumber, sell, assign, or transfer this Lease, in whole or in part, by operation of law or otherwise, or sublease all or any part of the Leased Premises, without Landlord's written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Landlord and Tenant agree that the specific provisions of this paragraph 15 are reasonable grounds for withholding consent. In all events no such assignment shall be valid unless, prior to the commencement of the subject sub-lease or the occupancy by the subject sub-tenant Tenant shall deliver to Landlord (i) a duplicate original instrument of assignment in form reasonably satisfactory to Landlord, duly executed by Tenant, and (ii) an instrument in form attached hereto as Exhibit I, duly executed by the Tenant and the assignee or sub-tenant, in which such assignee or sub-tenant shall agree, among other things, to observe and perform, and to be bound by, all of the terms, covenants, and conditions of this Lease on Tenant's part to be observed and performed accruing after the date of such assignment and whether or not relating to such assignment, and to deliver all payments due to Tenant under the subject sub-lease directly to Landlord upon receipt of written notice from Landlord.

(a) Right to Sublease: Tenant shall have the right to sublease or assign this Lease in whole, or in part, to its wholly owned subsidiaries or other entities which are in common control with Tenant or the Lease Guarantors, or to any corporation which is a successor to or assignee of Tenant by acquisition, merger or consolidation without Landlord's approval (a "Permitted Transfer"). However, in all events

Tenant and the Lease Guarantors shall remain primarily liable under the lease unless Landlord agrees in writing to replace Tenant and all Lease Guarantors as the primary party obligated under the Lease, which agreement by Landlord shall not be unreasonably withheld, conditioned, or delayed.

(b) Restrictions on Sub-leasing: It is understood and agreed that the overall make up of tenants and the size of sub-leased spaces within the Building is subject to the Landlord's sole and reasonable judgment and approval, not to be unreasonably withheld, conditioned, or delayed. The Landlord reserves the right to deny approval of a sub-lease to any party that the Landlord does not reasonably deem compatible as a tenant of the Building. Further, Landlord shall not be required to approve any sub-lease to a party that Landlord does not deem financially qualified to perform it's obligations under the sub-lease or the Lease, as reasonably determined by Landlord.

(c) Prior to Offering: In connection with any request by Tenant for consent to sublet all or any portion of the Leased Premises, Tenant shall, at least thirty (30) days prior to offering any space for sub-lease, submit to Landlord, in writing, a notice of Tenant's desire to sub-lease a portion of the Leased premises containing such information as the amount of proposed sub-lease space, the location of the proposed sub-lease space, an as-built floor plan of the proposed sub-lease space, the terms to be sought by Tenant under a sub-lease for the proposed sub-lease space, and the date of availability of the proposed sub-lease space. Landlord shall have the First Right of Refusal to all such space, as set forth below.

(d) Sub-tenant Identification: Upon identifying a proposed sub-lease tenant (a "Proposed Sub-tenant") or a proposed assignee (a "Proposed Assignee") Tenant shall submit to Landlord, in writing, a statement containing the name of the Proposed Assignee or Sub-tenant, such information as to its financial responsibility and standing of the Proposed Assignee or Sub-tenant as Landlord may require (including financial statements and information regarding the proposed Sub-Tenant), and all of the terms and provisions upon which the proposed assignment or sublease is to be made, and a floor plan delineating the proposed sublease area.

(e) Sub-lease Profits: Any profits from generating additional rent under such sub-lease by the sub-tenant shall be the shared fifty percent (50%) by Tenant and fifty percent (50) by Landlord. The profits, if any, will be those remaining after deducting Tenant's costs of sub-leasing, including only the commissions due the broker representing the sub-tenant, sub-tenant improvements paid for by Tenant above those provided by Landlord, and other monetary concessions made to the subject sub-tenant (the "Sub-lease costs") from the actual rent and payables under the Sub-lease. Any profits generated by the sale of special services provided by Landlord, including but not limited after hours HVAC services, to any sub-tenant of Tenant shall be the sole property of Landlord. In all events any sub-tenant shall be required to execute a sub-lease acknowledgement agreement in the form attached hereto as Exhibit I.

(f) Mortgagee Approval: In all events all proposed sub-leases of the Leased Premises shall be subject to the reasonable approval of any lender of Landlord that holds a mortgage on the Building, if such approval is required of Landlord under the terms of this Lease.

(g) First Right of Refusal: The Landlord shall at all times have the right of first refusal upon any portion of the Leased Premises that Tenant desires to sub-lease which right of first refusal may be assigned by Landlord. In the event the Landlord exercises this option the terms of the subject sub-lease shall be those readily available to Tenant from a third party. The foregoing portion of this sub-paragraph (g) shall not apply to Permitted Transfers.

(h) Invalid Transfers:, Any attempted transfer, assignment, sub-leasing, mortgaging or encumbering of this Lease in violation of the provisions of this Section shall be void and confer no rights upon any third person. No permitted assignment or subletting shall relieve Tenant of any of its obligations under this Lease, except as specifically provided for herein. Subject to the provisions of this paragraph 15, Landlord and Tenant agree that (i) any consideration paid to Tenant in connection with a

sub-leasing of all or any part of the Leased Premises which is attributable to an increase in the rental value of the Leased Premises over and above the Basic Rent and Additional Charges payable under this Lease, and (ii) any consideration paid to Tenant or any sub-tenant or other Person claiming through or under Tenant in connection with an assignment of the Tenant's interest in this Lease or the interest of any sub-tenant or other Person claiming though or under Tenant under any sub-lease, shall accrue to the benefit of Landlord and not to the benefit of Tenant, or any sub-tenant or other Person claiming through or under Tenant, or the creditors of Tenant or of any such sub-tenant or other Person claiming through or under Tenant

(i) Transfer of Control: If Tenant is a corporation, any transfer of any of Tenant's issued and outstanding capital stock or any issuance of additional capital stock, as a result of which the majority of the issued and outstanding capital stock of Tenant is held by a Person or Persons who do not hold a majority of the issued and outstanding capital stock of Tenant on the date hereof, shall be deemed an assignment under this Section 15. If Tenant is a partnership, or limited liability company, any transfer of any interest in the partnership, or limited liability company, or any other change in the composition of the partnership, or limited liability company, which results in a change in the control of Tenant from the Person or Persons controlling the partnership, or limited liability company, on the date hereof, shall be deemed an assignment under this Section 15. The provisions of this subsection (i) shall not apply to Permitted Transfers.

(j) Obligations of Assignee or Subtenant: If Tenant's interest in this Lease is assigned, whether or not in violation of the provisions of this Section, Landlord may collect rent from the assignee; if the Leased Premises or any part thereof are sub-leased to, or occupied by, or used by, any Person other than Tenant, whether or not in violation of this Section, Landlord, may at its option collect rent from the sub-tenant, user or occupant. In either case, Landlord shall apply the amount collected to the rents reserved in this Lease, but neither any such assignment, sub-leasing, occupancy, or use, whether with or without Landlord's prior consent, nor any such collection or application, shall be deemed a waiver of any term, covenant or condition of this Lease or the acceptance by Landlord of such assignee, sub-tenant, occupant or user as tenant. The consent by Landlord to any further assignment or sub-leasing shall not relieve Tenant from its obligation to obtain the express prior consent of Landlord to any further assignment or sub-leasing. The listing of any name other than that of Tenant on any door of the Leased Premises or on any directory in the Building, or otherwise, shall not operate to vest in the Person so named any right or interest in this Lease or in the Leased Premises or be deemed to constitute, or serve as a substitute for, any prior consent of Landlord required under this Section, and it is understood that any such listing shall constitute a privilege extended by Landlord which shall be revocable at Landlord's will by notice to Tenant, except where there exists a valid sublease. Neither an assignment of Tenant's interest in this Lease nor a sub-leasing, occupancy or use of the Leased Premises or any part thereof by any Person other than Tenant, nor the collection of rent by Landlord from any Person other than Tenant as provided in this subsection, nor the application of any such rent as provided in this subsection shall, in any circumstances, relieve Tenant from its obligation fully to observe and perform the terms, covenants and conditions of this Lease on Tenant's part to be observed and performed.

16. DEFAULT PROVISIONS

(a) Each of the following events shall be deemed to be, and is referred to in this Lease as, an "Event of Default":

(1) A default by Tenant in the due and punctual payment of any Basic Rent or Additional Charges, which continues for more than five (5) days after such Basic Rent or Additional Charges shall be due and payable; or

(2) The neglect or failure of Tenant to perform or observe any of the terms, covenants, or conditions contained in this Lease on Tenant's part to be performed or observed (other than those referred to in paragraph (1) above) which is not remedied by Tenant within thirty (30) days after Landlord shall have given to Tenant written notice specifying such neglect or failure; or if such condition can not practically be remedied within said thirty (30) day period Tenant shall have sixty (60) days from the date of such notice to remedy the condition provided Tenant timely commences and diligently prosecutes such remedy unless the nature of such condition requires it to be remedied in a shorter period of time: or: or

(3) The assignment, transfer, mortgaging, or encumbering of this Lease or the sub-leasing of any or all of the Leased Premises in a manner not strictly in accordance with and permitted by Section 15; or

(4) The taking of this Lease or the Leased Premises, or any part thereof, upon execution or by other process of law directed against Tenant, or upon or subject to any attachment at the instance of any creditor of or claimant against Tenant, which execution or attachment shall not be discharged or disposed of within sixty (60) days after the levy thereof; or

(5) The abandonment of the Leased Premises by Tenant.

(6) The failure of any sub-tenant occupying any portion of the Leased Premises to comply with each and every provision of this Lease or the Default of any sub-tenant under any sub-lease agreement, subject to the applicable cure periods of this Lease, which Tenant shall always have the right to cure.

(b) Upon the occurrence of an Event of Default, Landlord shall have the right, at its election, then or at any time thereafter while such Event of Default shall continue, either:

(1) To give Tenant written notice that this Lease will terminate on a date to be specified in such notice, which date shall not be less than thirty (30) days after such notice, and on the date specified in such notice Tenant's right to possession of the Leased Premises shall cease and this Lease shall thereupon be terminated, but Tenant shall remain liable as provided in subsection (c);or

(2) Without demand or notice, to re-enter and take possession of the Leased Premises, or any part thereof, and repossess the same as of Landlord's former estate and expel Tenant and those claiming through or under Tenant a right to occupy the Leased Premises, and remove the effects of both or either, either by summary proceedings, or by action at law or in equity or by force (if necessary) or otherwise, without being deemed guilty of any manner of trespass and without prejudice to any remedies for arrears of rent or preceding breach of covenant.

If Landlord elects to re-enter the Leased Premises as set forth above, Landlord may terminate this Lease, or, from time to time, without terminating this Lease, may release the Leased Premised, or any part thereof, as agent for Tenant for such term or terms and conditions as Landlord may deem advisable, with the right to make alterations and repairs to the Leased Premises. No such re-entry or taking of possession of the Leased Premises by Landlord shall be construed as an election on Landlord's part to terminate this Lease unless a written notice of such intention is given to Tenant as set forth above or unless the termination thereof be decreed by a court of competent jurisdiction. Tenant waives any right to the service of any notice of Landlord's intention to re-enter provided for by any present or future law.

(c) If Landlord terminates this Lease pursuant to subsection (b), Landlord shall have the option to accelerate and declare the entire amount of all Basic Rent and Additional Charges provided for herein until the date this Lease would have expired had such termination not occurred as the total rental set forth in Section (a) (1) of this Paragraph as due and payable forthwith. Tenant shall be liable (in addition to accrued liabilities) to the extent legally permissible for (i) the sum of (A) all Basic Rent and Additional Charges provided for in this Lease until the date this Lease would have expired had such termination not occurred, and (B) any and all reasonable expenses incurred by Landlord in re-entering the Leased Premises, repossessing the same, making good any default of Tenant, painting the same, adjoining the same with any adjacent space for any new tenants, putting the same in proper repair, re-letting the same (including any and all reasonable attorneys' fees and disbursements and reasonable brokerage fees incurred with so doing), and any and all expenses which Landlord may incur during the occupancy of any new tenant (other than expenses of a type that are Landlord's responsibility under the terms of this Lease); less (ii) the net proceeds of any re-lotting.

In addition to the foregoing, Tenant shall pay to Landlord such sums as the court which has jurisdiction thereover may adjudge reasonable as attorney's fees with respect to any successful law suit or action instituted by Landlord to enforce the provisions of this Lease. Landlord shall have the right,

at its sole option, to release the whole or any part of the Leased Premises for the whole of the un-expired Term, or longer, or from time to time for shorter periods, for any rental then obtainable, giving such concessions of rent and making such special repairs, alterations, decorations, and paintings for any new tenant as Landlord, in its sole and absolute discretion, may deem advisable. Tenant's liability as aforesaid shall survive the institution of summary proceedings and the issuance of any warrant thereunder. Landlord shall be under no obligation to re-lease the Leased Premises, but agrees to use its best efforts to do so.

(d) Notwithstanding the terms and conditions of this Paragraph 16, with regard only to an Event of Default as set forth in Paragraph 16 (a) (1), Landlord shall provide Tenant written notice of such Event of Default and the right to cure such Event of Default by payment of all amounts due Landlord within fifteen (15) business days after such notice is given (as set forth in Paragraph 30 (d)) once in any calendar year.

17. BANKRUPTCY TERMINATION PROVISION

This Lease shall automatically terminate and expire, without the performance of any act or the giving of any notice by Landlord, upon the occurrence of any of the following events: (1) Tenant's admitting in writing its inability to pay its debts generally as they become due, or (2) the commencement by Tenant or any Lease Guarantor of a voluntary case under the federal bankruptcy laws, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency, or other similar law, or (3) the entry of a decree or order for relief by a court having jurisdiction in the premises in respect of Tenant or any Lease Guarantor in an involuntary case under the federal bankruptcy laws, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar law, and the continuance of any such decree or order unstayed and in effect for a period of sixty (60)) consecutive days, or (4) Tenant's making an assignment of all or a substantial part of its property for the benefit of its creditors, or (5) Tenant's or any Lease Guarantor's seeking or consenting to or acquiescing in the appointment of, or the taking of possession by, a receiver, trustee or custodian for all or a substantial part of its property, or (6) the entry of a court order without Tenant's or any Lease Guarantor's consent, which order shall not be vacated, set aside or stayed within sixty (60) days from the date of entry, appointing a receiver, trustee, or custodian for all or a substantial part of its property. The provisions of this Section shall be construed with due recognition for the provisions of the federal bankruptcy laws, where applicable, but shall be interpreted in a manner which results in a termination of this Lease in each and every instance, and to the fullest extent that such termination is permitted under the federal bankruptcy laws, it being of prime importance to the Landlord to deal only with tenants who have, and continue to have, a strong degree of financial strength and financial stability.

18. LANDLORD MAY PERFORM TENANT'S OBLIGATIONS If Tenant shall fail to keep or perform any of its obligations as provided in this Lease in respect to (a) maintenance of insurance, (b) repairs and maintenance of Leased Premises, (c) compliance with Legal Requirements, or (d) the making of any other payment or performance of any other obligation, then Landlord may (but shall not be obligated to) upon the continuance of such failure on Tenant's part for ten (10) days after written notice to Tenant (or after such additional period, if any, as Tenant may reasonably require to cure such failure if of a nature which cannot be cured within said 10-day period), or without notice in the case of an emergency, and without waiving or releasing Tenant from any obligation, and as an additional but not exclusive remedy, make any such payment or perform any such obligation and all sums so paid by Landlord and all necessary incidental costs and expenses, including attorney's fees, incurred by Landlord in making such payment or performing such obligation, together with interest thereon from the date of payment at the Default Interest Rate, shall be deemed additional rent and shall be paid to the Landlord on demand, or at Landlord's option may be added to any installment of Basic Rent thereafter falling due, and if not so paid by Tenant, Landlord shall have the same rights and remedies as in the case of a default by Tenant in the payment of Basic Rent.

19. SECURITY DEPOSIT

(a) Upon execution of this Lease, Tenant shall pay Landlord a Security Deposit equal to one (1) month rent in cash.

(b) As consideration for Landlord entering into this Lease Agreement the Tenant hereby expressly waives and relinquishes any and all right Tenant may have to earn interest on the cash Security Deposit delivered to Landlord. The Landlord shall be free from any restrictions of any kind whatsoever on the use of the cash Security Deposit and shall not be required to hold the cash Security Deposit in a special account (or in any account) and may utilize the cash Security Deposit as its own funds.

(c) Tenant hereby deposits with Landlord the Security Deposit, as security for the prompt, full, and faithful performance by Tenant of each and every provision of this Lease and of all obligations of Tenant hereunder. If an Event of Default occurs, Landlord may use, apply, or retain the whole or any part of the Security Deposit for the payment of (i) any Basic Rent or Additional Charges which Tenant may not have paid or which may become due after the occurrence of such Event or Default. (ii) any sum expended by Landlord on Tenant's behalf in accordance with the provisions of this Lease (including the reimbursement of the Tenant Improvement Allowance provided by Landlord), or (iii) any sum which Landlord may expend or be required to expend by reason of Tenant's default, including damages or deficiency in the releasing of the Leased Premises as provided in Section 16. The use, application, or retention of the Security Deposit, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by law and shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. If any portion of the Security Deposit is used, applied or retained by Landlord for the purpose set forth above, Tenant agrees, within ten (10) days after a written demand therefore is made by Landlord, to deposit cash with the Landlord in an amount sufficient to restore the Security Deposit to its original amount.

(d) If Tenant shall fully and faithfully comply with all of the provisions of this Lease, the Security Deposit, or any balance thereof, shall be returned to Tenant within thirty (30)days after the expiration of the Term, without interest. In the absence of evidence satisfactory to Landlord of any permitted assignment of the right to receive the Security Deposit, or the remaining balance thereof, Landlord may return the same to the original Tenant, regardless of one or more assignments of Tenant's interest in this Lease or the Security Deposit. In such event, upon the return of the Security Deposit (or balance thereof) to the original Tenant, Landlord shall be completely relieved of liability under this Section.

(e) In the event of a transfer of Landlord's interest in the Leased Premises, Landlord shall have the right to transfer the Security Deposit to the transferee thereof subject to sub-paragraph (d) above. In such event, upon the delivery by Landlord to Tenant of such transferee's written acknowledgement of its receipt of such Security Deposit, Landlord shall be deemed to have been released by Tenant from all liability or obligation for the return of such Security Deposit, and Tenant agrees to look solely to such transferee for the return of the Security Deposit and the transferee shall be bound by all provisions of this Lease relating to the return of the Security Deposit.

(f) The Security Deposit shall not be mortgaged, assigned, or encumbered in any manner whatsoever by Tenant without the prior written consent of Landlord, which may be withheld by Landlord in its sole discretion.

20. SUBORDINATION

(a) This Lease and Tenant's interest hereunder shall have priority over, and be senior to, the lien of any Mortgage made by Landlord after the date of this Lease. However, if at any time or from time to time during the Term, a Mortgagee or prospective Mortgagee requests that this Lease be subject and subordinate to its Mortgage, and if Landlord consents to such subordination, this Lease and Tenant's interest hereunder shall be subject and subordinate to the lien of such Mortgage and to all renewals,

modifications, replacements, consolidations, and extensions thereof and to any and all advances made thereunder and the interest thereon. Tenant agrees that, within ten (10) days after receipt of a written request therefor from Landlord, it will, from time to time, execute and deliver any instrument or other document required by any such Mortgagee to subordinate this Lease and its interest in the Leased Premises to the lien of such Mortgage, provided any such instrument or other document is in form and content as would be customary in the industry and does not materially modify or amend the terms and conditions of this lease. If, at any time or from time to time during the Term, a Mortgagee of a Mortgage made prior to the date of this Lease shall request that this Lease have priority over the lien of such Mortgage, and if Landlord consents thereto, this Lease shall have priority over the lien of such Mortgage and all renewals, modifications, replacements, consolidations, and extensions thereof and all advances made thereunder and the interest thereon, and Tenant shall, within ten (10) days after receipt of a written request therefor from Landlord, execute, acknowledge and deliver any and all documents and instruments confirming the priority of this Lease, provided any such instrument or other document is in form and content as would be customary in the industry and does not materially alter the terms and conditions of this lease. In addition, the Mortgagee of a Mortgage which has priority over this Lease shall have the right, at its option, to subordinate the lien of its Mortgage, in whole or in part, to this Lease by recording a unilateral declaration to that effect among the applicable Land Records. In any event, however, if this Lease shall have priority over the lien of a first Mortgage, this Lease shall not become subject or subordinate to the lien of any subordinate Mortgage, and Tenant shall not execute any subordination documents or instruments for any subordinate Mortgagee, without the written consent of the first Mortgagee.

(b) This Lease and Tenant's interest hereunder shall be subject and subordinate to each and every ground or underlying lease hereafter made of the Building or the land on which it is constructed, or both, and to all renewals, modifications, replacements, and extensions thereof. Tenant agrees that, within ten (10) days after receipt of written request therefor from Landlord, it will, from time to time, execute, acknowledge and deliver any instrument or other document required by any such lessor to subordinate this Lease and its interest in the Leased Premises to such ground or underlying lease, provided any such instrument or other document is in form and content as would be customary in the industry and does not materially modify or amend the terms and conditions of this lease.

(c) If (i) the Building, or any part thereof, or the land on which the Building is constructed, or the Landlord's leasehold estate in the Building, is at any time subject to a first Mortgage, and Landlord has entered into an assignment of this Lease to the holder of said first Mortgage, and (ii) the Tenant is given written notice of such assignment, including the name and address of the assignee, then, in that event, Tenant shall not terminate this Lease or make any abatement in the Basic Rent payable hereunder for any default on the part of the Landlord without first giving written notice, in the manner provided elsewhere in this Lease for the giving of notice, to such first Mortgagee, specifying the default in reasonable detail, and affording such first Mortgagee a reasonable opportunity to make performance, at its election, for and on behalf of the Landlord.

21. ATTORNMENT

In the event of (a) a transfer of Landlord's interest in the Leased Premises, (b) the termination of any ground or underlying lease of the Building or the land on which it is constructed, or both, or (c) the purchase of the Building or Landlord's interest therein in a foreclosure sale or by deed in lieu of foreclosure under any Mortgage or pursuant to a power of sale contained in any Mortgage, then in any of such events Tenant shall, upon demand by the owner of the Building or the land on which it is constructed, or both, attorn to and recognize the transferee or purchaser of Landlord's interest or the lessor under the terminated ground or underlying lease, as the case may be, as Landlord under this Lease for the balance then remaining of the Term, and thereafter this Lease shall continue as a direct lease between such person, as "Landlord," and Tenant, as "Tenant," except that such lessor, transferee or purchaser shall not be liable for any act or omission of Landlord prior to such lease termination or

prior to such person's succession to title, nor be subject to any offset, defense or counterclaim accruing prior to such lease termination or prior to such person's succession to title, nor be bound by any payment of Basic Rent or Additional Charges prior to such lease termination or prior to such person's succession to title for more than one (1) month in advance. Tenant shall, upon request by Landlord or the transferee or purchaser of Landlord's interest or the lessor under the terminated ground or underlying lease, as the case may be, execute and deliver an instrument or instruments confirming the foregoing provisions of this Section, provided any such instrument or other document is in form and content as would be customary in the industry and does not materially modify or amend the terms and conditions of this lease. Tenant hereby waives the provisions of any present or future law or regulation which gives or purports to give Tenant any right to terminate or otherwise adversely affect this Lease, or the obligations of Tenant hereunder, upon or us a result of the termination of any such ground or underlying lease or the completion of any such foreclosure and sale.

22. QUIET ENJOYMENT

Landlord covenants that Tenant, upon paying the Basic Rent and the Additional Charges provided for in this Lease, and upon performing and observing all of the terms, covenants, conditions, and provisions of this Lease on Tenant's part to be kept, observed and performed, shall quietly hold, occupy, and enjoy the Leased Premises during the Term without hindrance, ejection, or molestation by Landlord or any party lawfully claiming through or under Landlord. Landlord will provide Tenant a reasonable non-disturbance agreement from any current and/or future mortgagees. In connection therewith Tenant shall execute documents reasonably requested by such lender, provided any such instrument or other document is in form and content as would be customary in the industry and does not modify or amend the terms and conditions of this lease.

23. LANDLORD'S RIGHT OF ACCESS TO LEASED PREMISES

(a) Landlord and its agents shall have the following rights in and about the Leased Premises: (i) to enter the Leased Premises at all reasonable times and with reasonable notice (which shall be at least two days except in the case of emergency) to examine the Leased Premises or for any of the purposes set forth in this section or for the purpose of performing any obligation of Landlord under this Lease or exercising any right or remedy reserved to Landlord in this Lease, and if Tenant, its officers, partners, agents, or employees shall not be personally present or shall not open and permit an entry into the Leased Premises at any time when such entry shall be necessary or permissible, to use a master key or forcibly to enter the Leased Premises; (ii) to erect, install, use, and maintain pipes, ducts, and conduits in and through the Leased Premises which, when completed, will not substantially interfere with the use or appearance or materially reduce the space afforded to Tenant in the Leased Premises; (iii) to exhibit the Leased Premises to others at reasonable times and for reasonable purposes; (iv) to make such decorations, repairs, alterations, improvements, or additions, or to perform such maintenance, including, but not limited to, the maintenance of all heating, air-conditioning, elevator, plumbing, electrical and other mechanical facilities installed by Landlord, as Landlord may deem necessary or desirable; (v) to take all materials into and upon the Leased Premises that may be required in connection with any such decorations, repairs, alterations, improvements, additions, or maintenance; and (vi) to alter, renovate and decorate the Leased Premises at any time during the Term if Tenant shall have removed all or substantially all of Tenant's property from the Leased Premises. Landlord agrees to give prior notice before it exercises its rights under this subsection, except that Landlord may enter the Leased Premises without notice in the case of an emergency. In making such an entry, Landlord agrees to use reasonable efforts to avoid interfering with the regular and usual conduct of the Tenant's business. Tenant shall at all times have the option of accompanying Landlord or its agents when Landlord or its agents enter the Leased Premises.

(b) All parts (except surfaces facing the interior of the Leased Premises) of all walls, windows, and doors bounding the Leased Premises (including exterior Building walls, corridor walls, doors, and

entrances), all balconies, terraces, and roofs adjacent to the Leased Premises, all space in or adjacent to the Leased Premises used for shafts, stacks, stairways, chutes, pipes, conduits, ducts, fan rooms, heating, and air-conditioning, plumbing, electrical, and other mechanical facilities installed by Landlord, service closets and other Building facilities, and the use thereof, as well as access thereto through the Leased Premises for the purposes of operation, maintenance, alteration, and repair, are hereby reserved to Landlord. Nothing contained in this Section shall impose any obligation upon Landlord with respect to the operation, maintenance, alteration, or repair of the Leased Premises or the Building.

(c) The exercise by Landlord or its agents of any right reserved to Landlord in this Section shall not constitute an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution of rent, or relieve Tenant from any of its obligations under this Lease, or impose any liability upon Landlord, or its agents, or upon any lessor under any ground or underlying lease, by reason of inconvenience or annoyance to Tenant, or injury to or interruption of Tenant's business, or otherwise. Landlord agrees to exercise its rights under this Section in a manner designed to minimize interference with Tenant's normal business operations, without any obligation, however, to employ labor at overtime or other premium pay rates. Landlord shall take reasonable steps to insure that the exercise by Landlord or its agents of any right reserved to Landlord in this Section does not interfere with the Tenant conducting its business.

24. LIMITATION ON LANDLORD'S LIABILITY

(a) Except for damages resulting from the willful or negligent act or omission of Landlord, its agents and employees, Landlord shall not be liable to Tenant, its employees, agents, business invitees, licensees, customers, guests or trespassers, for any damage or loss to the property of Tenant or others located on the Leased Premises, or in the Building or the land on which it is built, or for any accident or injury to Persons in the Leased Premises or the Building, resulting from the necessity of repairing any portion of the Building; the use or operation (by Tenant or any other Person or Persons whatsoever) of any elevators, or heating, cooling, electrical or plumbing equipment or apparatus; the termination of this Lease by reason of the destruction of the Building or the Leased Premises; any fire, robbery, theft, and/or any other casualty; any leaking in any part of the Leased Premises; any water, gas, steam, fire, explosion, electricity or falling plaster; the bursting, stoppage or leakage of any pipes, sewer pipes, drains, conduits, appliances or plumbing works; or any other cause whatsoever.

(b) Landlord shall not be required to perform any of its obligations hereunder, nor be liable for loss or damage for failure to do so, nor shall Tenant be released from any of its obligations under this Lease because of the Landlord's failure to perform, where such failure arises from or through Unavoidable Delays or Legal Requirements. If Landlord is so delayed or prevented from performing any of its obligations during the Term, the period of such delay or such prevention shall be deemed added to the time herein provided for the performance of any such obligation.

25. ESTOPPEL CERTIFICATES

Tenant agrees from time to time, within ten (10) days after written request therefor by Landlord, to execute, acknowledge and deliver to Landlord a statement in writing certifying to Landlord, any Mortgagee, assignee of a Mortgagee, or any purchaser of the Building or the land on which it is constructed, or both, or any other Person designated by Landlord, as of the date of such statement, to the extent of Tenant's knowledge (i) that Tenant is in possession of the Leased Premises; (ii) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect as modified and setting forth such modifications); (iii) whether or not there are then existing any set-offs or defenses known to Tenant against the enforcement of any right or remedy of Landlord, or any duty or obligation of Tenant, hereunder (and, if so, specifying the same in detail); (iv) the dates, if any, to which any Basic Rent or Additional Charges have been paid in advance; (v) that Tenant has no knowledge of any uncured defaults on the part of Landlord under this Lease

(or, if Tenant has such knowledge, specifying the same in detail); (vii) the amount of any Security Deposit held by Landlord; and (viii) any additional facts reasonably requested by any such Mortgagee, assignee or a Mortgagee or purchaser.

Landlord agrees from time to time, within ten (10) days (or as soon as reasonably practical but not more then thirty (30) days), after written request therefor by Tenant to execute, acknowledge and deliver to Tenant a statement in writing certifying to Tenant, any Mortgagee, assignee of a Mortgagee, or any purchaser of or successor in interest to Tenant, or any other Person designated by Tenant, as of the date of such statement, to the extent of Landlord's actual knowledge (i) that Landlord is the owner of the Building and the Land; (ii) that Tenant is in possession of the Leased Premises; (ii) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect as modified and setting forth the dates of such modifications); (iii) the dates, if any, to which any Basic Rent or Additional Charges have been paid in advance; and (iv) the amount of any Security Deposit held by Landlord;

(b) The provisions of this Section shall survive any expiration or termination of this Lease.

27. HOLDING OVER

If Tenant shall hold over possession of the Leased Premises after the end of the Term, Tenant shall be deemed to be occupying the Leased Premises as a Tenant from month to month, at 110% of the Basic Rent, adjusted to a monthly basis, and subject to all the other conditions, provisions and obligations of this Lease insofar as the same are applicable, or as the same shall be adjusted, to a month-to-month tenancy. Notwithstanding the immediately preceding sentence the Tenant shall have the right to hold over for a period of up to two (2) months following the expiration of the Lease Term, or any extension thereof, at 100% of the Base Rent in effect during the last month of the previous Lease Term with six (6) months written notice to Landlord. Thereafter the holdover rent will be at 110% of the Base Rent in effect during the last month of the previous Lease Term plus consequential damages, if any.

28. PARKING

Tenant will have the right to utilize Tenant's Proportionate Share of the reserved and un-reserved parking spaces in the project's parking structure and in the surface parking lots at no cost during the initial Lease Term. Throughout the Term, Tenant and/or its employees shall have the right, without additional cost, to park their automobiles in the surface and garage parking areas provided for the Building. Such parking spaces shall be available on a first-come, first-served basis, subject however, to the rights of any other tenant of the Building to park automobiles in reserved parking spaces as provided in its lease. Landlord shall use good faith, reasonable efforts to insure that Tenant continuously is able to use Tenant's Proportionate Share of the parking spaces. Landlord reserves the right, at any time or from time to time during the Term, to establish reserved parking spaces for the tenant's in the Building on part of or all of the parking spaces on the Property and in such event Tenant shall utilize only those reserved spaces assigned to Tenant, Landlord reserves the right, at any time or from time to time during the Term, to control access to the surface and garage parking areas, by use of mechanical or electric devices or otherwise, to tenants of the Building and their employees, provided that Landlord shall reserve at least sixteen (16) parking spaces for parking of visitors of the Building. If at any time during the Term, Landlord implements a controlled access system for the

Building parking areas, Tenant shall have the right without additional cost, to use unassigned parking spaces in the structured parking and the surface parking lots based on Tenant's Proportionate Share. Neither Tenant nor any of its employees shall use any of the parking facilities for storage of vehicles (or any other item such as boats or trailers) or park its or their automobiles in any portion of the Building parking areas reserved for visitor or handicapped parking or for parking of automobiles belonging to other tenants of the Building. Tenant shall be provided reserved parking spaces (including covered parking spaces) as detailed on the Reserved Parking Plan attached hereto as EXHIB1T G.

29. LEASING COMMISSION

Landlord and Tenant each represent and warrant to the other that neither of them has employed any broker in carrying on the negotiations relative to this Lease. Landlord and Tenant shall each indemnify and hold harmless the other from and against any claim or claims for brokerage or other commission arising from or out of any breach of the foregoing representation and warranty.

30. GENERAL PROVISIONS

(a) The covenants, conditions, agreements, terms and provisions herein contained shall be binding upon, and shall inure to the benefit of, the parties hereto and, subject to the provisions of Section 15, each of their respective personal representatives, successors and assigns.

(b) Tenant agrees to provide Landlord with reasonable documentation evidencing the Tenant's financial viability and good standing as may be requested from time to time by Landlord or Landlord's mortgage holder.

(c) It is the intention of the parties hereto that this Lease (and the terms and provisions hereof) shall be construed and enforced in accordance with the laws of the Commonwealth of Virginia.

(d) No failure by Landlord to insist upon the strict performance of any term, covenant, agreement, provision, condition or limitation of this Lease or to exercise any right or remedy consequent upon a breach thereof, and no acceptance by the Landlord of full or partial rent during the continuance of any such breach, shall constitute a waiver of any such breach or of any such term, covenant, agreement, provision, condition, limitation, right or remedy.

It is understood and agreed that the common ownership and control of the Landlord and the Tenant is in contributing factor to the Landlord agreeing to lease the Leased Premises to Tenant and Tenant agreeing to lease the Leased Premises from Landlord.

(a) the Operating Expenses that are the responsibility of Tenant as set forth in paragraph 1(b) hereof for any calendar year that completes after the date of a Landlord Transfer shall be capped (and shall not exceed) the amount of such Operating Expenses that were the responsibility of the Tenant in the preceding calendar year.

(b) the profits generated by the sub-lease of the Leased Premises by Tenant shall belong to Tenant and shall not be shared between Tenant and Landlord as set forth in paragraph 15(e) hereof.

However, it is agreed and understood that the provisions of sub-paragraphs 30(a), (b), (c), and (d) above are intended for the sole benefit of the Tenant and the Lease Guarantors and their respective current shareholders. In the event that the shareholders (including their respective estates) of the Tenant or the Lease Guarantors whom hold a majority of the outstanding shares of company stock no longer own a majority of the outstanding shares of company stock, or otherwise lose their controlling interest and rights to management of the Tenant and the Lease Guarantor (a "Tenant Transfer") during the Term the provisions of this Paragraph 30 shall be null and void and of no consequence as if never included in this Lease.
