Subject to Tenant's exercise of the opinion to terminate as ---------- set forth in Article 28, the Term shall commence on the Commencement Date and expire at midnight on the Expiration Date for occupancy purposes and shall commence on the Rent Commencement Date and expire on midnight on the Expiration Date for payment of Rent purposes. Landlord and Tenant acknowledge that Tenant is occupying a Substantial Part of the space comprising the Premises pursuant to a prior lease which is scheduled to expire prior to the Commencement Date. Landlord shall accept the Premises in "as is" condition subject to the work to be performed pursuant to Exhibit B, attached hereto. If requested by Landlord, --------- Tenant shall within fifteen (15) days -7- of such request sign a declaration acknowledging the Commencement Date, the Rent Commencement Date and the Expiration Date in the form attached hereto and made a part hereof as Exhibit D --------- ARTICLE 5: RENT 5.1 Base Rent. Tenant shall pay to Landlord the Base Rent as specified in --------- Section 1.7. 5.2 Payment of Base Rent. Subject to Subsections 21.1 and 21.2, Base Rent -------------------- for each Lease Year shall be payable in equal monthly installments, in advance, without demand, notice, deduction, offset or counterclaim, on or before the first day of each and every calendar month during the Term. If the Commencement Date occurs on a date other than on the first day of a calendar month, Base Rent shall be prorated from such date until the first day of the following month. Tenant shall pay the Base Rent and all Additional Rent, by good check or in lawful currency of the United States of America, to Landlord at the address set forth in Section 1.17 herein, or to such other address or in such other manner as Landlord from time to time specifies by written notice to Tenant. Any payment made by Tenant to Landlord on account of Base Rent may be credited by Landlord to the payment of any late charges then due and payable and to any Base Rent or Additional Rent then past due before being credited to Base Rent currently due. 5.3 Additional Rent. All sums payable by Tenant under this Lease, other --------------- than Base Rent, shall be deemed "Additional Rent," and, unless otherwise set forth herein, shall be payable in the same manner as set forth above for Base Rent. Whenever the word "rent" or "Rent" is used in this Lease it shall be deemed to include Additional Rent unless the context specifically or clearly implies that only the Base Rent is referenced. All remedies available to Landlord pursuant to the terms of this Lease for non-payment of Base Rent shall be applicable for non-payment of Additional Rent. 5.4 Acceptance of Rent. If Landlord shall direct Tenant to pay Base Rent or ------------------ Additional Rent to a "Lockbox" or other depository whereby checks issued in payment of Base Rent or Additional Rent (or both, as the case may be) are initially cashed or deposited by a person or entity other than Landlord (albeit on Landlord's authority), then, for any and all purposes under this Lease: (i) Landlord shall not be deemed to have accepted such payment until ten (10) days after the date on which Landlord shall have actually received such funds, and (ii) Landlord shall be deemed to have accepted such payment if (and only if) within said ten (10) day period, -8- Landlord shall not have refunded (or attempted to refund) such payment to Tenant. Nothing contained in the immediately preceding sentence shall be construed to place Tenant in default of Tenant's obligation to pay Rent if and for so long as Tenant shall timely pay the Rent required pursuant to this Lease in the manner designated by Landlord. ARTICLE 6: SECURITY DEPOSIT 6.1 General. Simultaneously with the execution of this Lease, Tenant shall ------- deposit in the form of cash or an irrevocable letter of credit the Security Deposit with Landlord, which shall be held by Landlord, without obligation for interest, as security, for the performance of Tenant's obligations and covenants under this Lease. It is expressly understood and agreed that such deposit is not an advance rental deposit or a measure of Landlord's damages in case of an Event of Default. Landlord shall endeavor in good faith and use its reasonable efforts to conduct a "Post Move-Out Inspection" of the Premises within ten (10) business days after the Expiration Date or earlier termination of this Lease, and Tenant shall be notified of the date for and have the right to be present at such Post Move-Out Inspection. If there has not been an Event of Default (beyond applicable notice and cure periods) during the first five (5) Lease Years and Tenant has maintained a substantial net worth, Landlord shall return the Security Deposit or any remaining balance thereof to Tenant within thirty (30) days after the expiration of the fifth (5th) Lease Year. Otherwise, Landlord shall return the Security Deposit or any remaining balance thereof to Tenant within thirty (30) days of the Post Move-Out Inspection. 6.2 Security in the Form of Cash. If an Event of Default shall occur or if ---------------------------- Tenant fails to surrender the Premises in the condition required by this Lease, Landlord shall have the right (but not the obligation), and without prejudice to any other remedy which Landlord may have on account thereof, to apply all or any portion of the Security Deposit to cure such default or to remedy the condition of the Premises. If Landlord so applies the Security Deposit or any portion thereof before the Expiration Date or earlier termination of this Lease, Tenant shall deposit with Landlord, upon written demand, the amount necessary to restore the Security Deposit to its original amount. The amounts deducted from the Security Deposit shall be the actual costs incurred to cure such default and shall not include items such as administrative fees and interest. The demand letter shall provide sufficient documentation to support such expenditures. If Landlord shall sell or transfer its interest in the -9- Building, Landlord shall have the right to transfer the Security Deposit to such purchaser or transferee, in which event Tenant shall look solely to the new landlord for the return of the Security Deposit, and Landlord thereupon shall be released from all liability to Tenant for the return of the Security Deposit. Although the Security Deposit shall be deemed the property of Landlord, any remaining balance of the Security Deposit shall be returned to Tenant within thirty (30) days of the Post Move-Out Inspection. 6.3 [Intentionally Deleted]. ARTICLE 7: OPERATING EXPENSES 7.1 Tenant's Proportionate Share of Operating Expenses. Tenant shall pay to -------------------------------------------------- Landlord throughout the Term, as Additional Rent, Tenant's Proportionate Share of the amount by which the Operating Expenses during each Calendar Year exceed the Operating Expenses during the Base Year for Operating Expenses. In the event that the Commencement Date or the Expiration Date are other than the first day of a Calendar Year then Tenant's Proportionate Share of the Operating Expenses shall be adjusted to reflect the actual period of occupancy during the Calendar Year. Notwithstanding the foregoing, any expense incurred by Landlord in maintaining Tenant's cooling tower and emergency generator as well as any expense incurred by Landlord in monitoring Tenant's Suite Access Control security system shall be directly passed through to Tenant. 7.2 Operating Expenses Defined. -------------------------- (a) As used herein, the term "Operating Expenses" shall mean all expenses, disbursements and costs of every kind and nature, consistent with similar first-class office buildings in Fairfax County, Virginia, which Landlord incurs because of or in connection with the ownership, maintenance, management, repair, alteration, replacement and operation of the Building (which expressly includes the Land, the Parking Facilities and the Common Area) including, without limitation, the following: (1) Wages and salaries of all employees, including without limitation an on-site management agent and staff, whether employed by Landlord or the Building's management company and all costs related to or associated with such employees or the carrying out of their duties, including uniforms and their cleaning, taxes, auto allowances and insurance and benefits (including, without limitation, contributions to -10- pension and/or profit sharing plans and vacation or other paid absences), provided such wages, salaries and related costs are usual and customary for employees in similar positions;

If any amounts comprising Operating Expenses are incurred not just with respect to the office area of the Building, but also with respect to the retail area of the Building, if any, then Landlord shall endeavor in good faith and use its reasonable efforts to allocate such amounts between the office and retail areas of the Building.

Landlord shall submit to Tenant, before the ------------------ beginning of each Calendar Year, a statement of Landlord's estimate of the Operating Expenses payable by Tenant during such Calendar Year. In addition to the Base Rent, Tenant shall pay to Landlord on or before the first day of each month during such Calendar Year an amount equal to one-twelfth (1/12) of the estimated Operating Expenses payable by Tenant for such Calendar Year as set forth in Landlord's statement, subject, however, to Subsections 21.1 and 21.2 of this Lease. If Landlord fails to give Tenant notice of its estimated payments due under this Section for any Calendar Year, then Tenant shall continue making monthly estimated payments in accordance with the estimate for the previous Calendar Year until a new estimate is provided by Landlord. If Landlord determines that, because of unexpected increases in Operating Expenses or other reasons, Landlord's estimate of the Operating Expenses was too low, then Landlord shall have the right to give a new statement of the estimated -14- Operating Expenses due from Tenant for such Calendar Year or the balance thereof and to bill Tenant for any deficiency which may have accrued during such Calendar Year, and Tenant shall thereafter pay monthly estimated payments based on such new statement. 7.5 Actual Operating Expenses. Within one hundred twenty (120) days after ------------------------- the end of each Calendar Year, Landlord shall submit a statement to Tenant showing the actual Operating Expenses for such Calendar Year and Tenant's Proportionate Share of the amount by which such Operating Expenses exceed the Operating Expenses during the Base Year. If for any Calendar Year, Tenant's estimated monthly payments exceed Tenant's Proportionate Share of the amount by which the actual Operating Expenses for such Calendar Year exceed the Operating Expenses during the Base Year, then Landlord shall give Tenant a credit in the amount of the overpayment toward Tenant's next monthly payments of estimated Operating Expenses, unless the Lease has expired wherein Landlord shall send such refund to Tenant at Tenant's forwarding address. If for any Calendar Year Tenant's estimated monthly payments are less than Tenant's Proportionate Share of the amount by which the actual Operating Expenses for such Calendar Year exceed the Operating Expenses during the Base Year, then Tenant shall pay the total amount of such deficiency to Landlord within thirty (30) days after receipt of the statement from Landlord. Landlord's and Tenant's obligations with respect to any overpayment or underpayment of Operating Expenses shall survive the expiration or earlier termination of this Lease. 7.6 Tenant's Right to Audit. Tenant shall pay to Landlord all amounts ----------------------- payable pursuant to Sections 7.4 and 7.5 herein without off-set or deduction within the time periods provided for in each respective Section notwithstanding that Tenant may object to Landlord's statement rendered pursuant thereto.

Such audit shall occur upon not less than twenty (20) days prior written notice to Landlord, at Landlord's place of business or the actual location of Landlord's books and records if different from Landlord's place of business, during Landlord's -15- normal business hours. The amounts payable under this Section by Landlord to Tenant or by Tenant to Landlord, as the case may be, shall be appropriately adjusted on the basis of such audit. If such audit discloses a liability for further refund by Landlord to Tenant in excess of five percent (5%) of the payments previously made by Tenant for such Calendar Year, the actual out-of-pocket cost of such audit incurred by Tenant shall be borne by Landlord and paid within thirty (30) days of demand from Tenant subject to Landlord's right to dispute the results of Tenant's audit as hereinafter described: otherwise, the cost of such audit shall be borne by Tenant. Notwithstanding the foregoing, in no event shall Landlord's cost for such audit exceed Three Thousand Dollars ($3,000). If Tenant shall not request an audit in accordance with the provisions of this Section within sixty (60) days of receipt of Landlord's reconciliation statement of actual Operating Expenses, such statement shall be conclusive and binding upon Landlord and Tenant. ARTICLE 8: TAXES 8.1 Tenant's Proportionate Share of Real Estate Taxes. Tenant shall pay to ------------------------------------------------- Landlord throughout the Term, as Additional Rent, Tenant's Proportionate Share of the amount by which the Real Estate Taxes during each Calendar Year exceed the Real Estate Taxes for the Base Year for Real Estate Taxes. In the event the Commencement Date or the Expiration Date are other than the first day of a Calendar Year, the Tenant's Proportionate Share of the Real Estate Taxes shall be adjusted to reflect the actual period of occupancy during the Calendar Year. (a) As used herein, the term "Real Estate Taxes" shall mean all taxes and assessments, general or special, ordinary or extraordinary, foreseen or unforeseen, assessed, levied or imposed by any governmental authority upon the Building (which expressly includes the Land, the Parking Facilities and the Common Area) and upon the fixtures, machinery, equipment or systems in, upon or used in connection with any of the foregoing, and the rental, revenue or receipts derived therefrom, under the current or any future taxation or assessment system or modification of, supplement to, or substitute for such system.

If at any time the method of taxation prevailing at the Date of Lease shall be altered so that in lieu of, as a substitute for or in addition to the whole or any part of the taxes now levied or assessed, there shall be levied or assessed a tax of whatever nature, then the same shall be included as Real Estate Taxes hereunder. Further, for the purposes of this Article, Real Estate Taxes shall include the reasonable expenses (including, without limitation, attorneys' fees) incurred by Landlord in challenging or obtaining or attempting to obtain a reduction of such Real Estate Taxes, regardless of the outcome of such challenge. Notwithstanding the foregoing, Landlord shall have no obligation to challenge Real Estate Taxes. If as a result of any such challenge, a tax refund is made to Landlord, then the amount of such refund less the expenses of the challenge shall be deducted from Real Estate Taxes due in the Lease Year such refund is received. 8.2 Estimated and Actual Payments. Landlord shall charge Tenant for its ----------------------------- Proportionate Share of Real Estate Taxes and Tenant shall pay such charges in accordance with the procedures established under Sections 7.4 and 7.5 for payment of Operating Expenses.

Landlord shall have the right, from time ----------------------------- to time, without Tenant's consent, to change, alter, add to, temporarily close or otherwise affect the Parking Facilities in such manner as Landlord, in its sole discretion, deems appropriate including, without limitation, the right to designate reserved spaces available only for use by one or more tenants (however, in such event, those parking spaces shall still be deemed Common Area for the purpose of the definition of Operating Expenses), provided that, except in emergency situations or situations beyond Landlord's control, Landlord shall use commercially reasonable efforts to provide alternative Parking Facilities; provided, further, however, in no event shall Landlord's use of its discretion herein diminish Tenant's Parking Space Allocation at any time. -17- ARTICLE 10: USE 10.1 General. Tenant shall occupy the Premises solely for the Permitted Use ------- under Tenant's Trade Name. The Premises shall not be used for any other purpose without the prior written consent of Landlord, which consent shall not be unreasonably withheld, delayed or conditioned. Tenant shall comply, at Tenant's expense, with (i) all Legal Requirements applicable to the Premises, and (ii) any reasonable requests of Mortgagee or any insurance company providing coverage with respect to the Premises. Tenant shall not knowingly use or occupy the Premises or knowingly allow the Premises to be used in violation of any recorded covenants, conditions and restrictions affecting the Premises or the Building or of any Legal Requirements, or of any certificate of occupancy issued for the Premises or Building or in any manner that is dangerous or that shall constitute waste, unreasonable annoyance or a nuisance to Landlord or the other tenants of the Building. 10.2 Tenant's Personal Property. Tenant shall pay before delinquency any -------------------------- business, rent or other tax or fee that is now or hereafter assessed or imposed upon Tenant's use or occupancy of the Premises, the conduct of Tenant's business in the Premises or Tenant's Property. If any such tax or fee is enacted or altered so that such tax or fee is imposed upon Landlord or so that Landlord is responsible for collection or payment thereof, then Tenant shall pay the amount of such tax or fee as Additional Rent. 10.3 Indoor Air Quality. Tenant shall not permit any person to smoke ------------------ tobacco in any part of the Building except in those areas that are clearly designated by the Landlord as smoking areas and in the area used as Tenant's executive offices. Landlord reserves the right to prohibit all smoking in the Building. Tenant shall not use, store or handle or permit the usage, storing or handling of any materials in levels that exceed those established for indoor air quality pursuant to applicable Legal Requirements. -18- ARTICLE 11: ASSIGNMENT AND SUBLETTING 11.1 General. Except as otherwise expressly provided in this Article, 11, ------- no Transfer (as hereinafter defined) shall be permitted without Landlord's prior written consent which consent Landlord may withhold in its sole and absolute discretion. 11.2 Restriction on Transfer. Subject to the provisions of Sections 11.3, ----------------------- 11.4 and 11.5, Tenant shall not, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, delayed or conditioned, assign, or otherwise transfer or convey this Lease or any interest herein or sublet the Premises or any part thereof or enter into any licenses or concessions or permit the use and occupancy of the Premises by any party other than Tenant, its affiliates, subsidiaries, joint ventures or its Defense Contracting Audit Agency (DCAA) auditors or transfer the Premises or any part thereof by operation of law or other voluntary or involuntary transfer (any such assignment, sublease or any of the other foregoing shall sometimes be hereinafter referred to as a "Transfer). Tenant shall not mortgage or encumber this Lease or any interest herein without the prior written consent of Landlord, which consent may be withheld at Landlord's absolute discretion, and any such mortgage or encumbrance shall be deemed a "Transfer." Any Transfer without Landlord's consent shall constitute an Event of Default by Tenant under this Lease, without the benefit of any additional notice or cure period specified in Section 22.2(ii) herein, and in addition to all of Landlord's other remedies at law, in equity or under this Lease, such Transfer shall be voidable at Landlord's election. In addition, this Lease shall not, nor shall any interest of Tenant herein be assignable by operation of law without the written consent of Landlord. For purposes of this Article 11, if Tenant is a corporation, partnership or other entity, (i) any transfer, assignment, encumbrance or hypothecation of fifty percent (50%) or more (individually or in the aggregate) of any stock or other ownership interest in such entity, (ii) any transfer, assignment, hypothecation or encumbrance that changes the current management and effective control of Tenant's business by and from George J. Pedersen, and/or (iii) any transfer, assignment, hypothecation or encumbrance of any controlling ownership or voting interest in such entity, or any merger or consolidation in which the Tenant is involved, shall be deemed an assignment of this Lease and shall be subject to all of the restrictions and provisions contained in this Article 11. Notwithstanding the foregoing, the immediately preceding sentence shall not apply to any transfers of stock of -19- Tenant if Tenant is, or becomes, a publicly-held corporation and such stock is transferred publicly over a recognized security exchange or over-the-counter market. 11.3 Landlord's Options. If at any time or from time to time during the ------------------ Term, Tenant desires to effect a Transfer, Tenant shall deliver to Landlord written notice ("Transfer Notice") setting forth the terms and provisions of the proposed Transfer and the identity of the proposed assignee, sublessee or other transferee (sometimes referred to hereinafter as a "Transferee"). Tenant shall also deliver to Landlord with the Transfer Notice, a current financial statement and financial statements for the preceding two (2) years of the Transferee which have been certified or audited by a reputable independent accounting firm acceptable to Landlord, and such other information concerning the business background and financial condition of the proposed Transferee as Landlord may reasonably request. Landlord shall have the option, exercisable by written notice delivered to Tenant within twenty (20) days after Landlord's receipt of the Transfer Notice, such financial statements and other information, either to: (a) approve or disapprove such Transfer, which approval shall not be unreasonably withheld, delayed or conditioned; or (b) terminate this Lease with respect to the entire Premises in the case of a request to Transfer the entire Premises (or, in the case of a proposed Transfer of less than the entire Premises, only that portion of the Premises which the Tenant has requested to Transfer), which termination shall be effective thirty (30) days after Tenant's receipt of Landlord's notice. 11.4 Additional Conditions; Excess Rent. If Landlord does not exercise its ---------------------------------- termination option and instead approves of the proposed Transfer pursuant to Section 11.3(a) above, Tenant may enter into the proposed Transfer with such proposed Transferee subject to the following further conditions: (a) the Transfer shall be on the same terms set forth in the Transfer Notice delivered to Landlord (if the terms have materially changed, Tenant must submit a revised Transfer Notice to Landlord and Landlord shall have another twenty (20) days after receipt thereof to make the election in Section 11.3(a) or 11.3(b) above); -20- (b) no Transfer shall be valid and no Transferee shall take possession of the Premises until an executed counterpart of the assignment, sublease or other instrument effecting the Transfer has been delivered to Landlord pursuant to which the Transferee shall expressly assume all of Tenant's obligations under this Lease (or with respect to a sublease of a portion of the Premises or for a portion of the Term, all of Tenant's obligations applicable to such portion); (c) no Transferee shall have a further right to assign, encumber or sublet except on the terms herein contained; and (d) fifty percent (50%) of any rent or other economic consideration received by Tenant as a result of such Transfer which exceeds, in the aggregate, (i) the total rent which Tenant is obligated to pay Landlord under this Lease (prorated to reflect obligations allocable to any portion of the Premises subleased), plus (ii) any reasonable brokerage commissions, attorneys' fees and moving costs actually paid by Tenant in connection with such Transfer, shall be paid to Landlord within ten (10) days after receipt thereof as Additional Rent under this Lease, without affecting or reducing any other obligations of Tenant hereunder. 11.5 Reasonable Disapproval. Landlord and Tenant hereby acknowledge that ---------------------- Landlord's disapproval of any proposed Transfer pursuant to Section 11.3(a) shall be deemed reasonably withheld if based upon any reasonable factor, including, without limitation, any or all of the following factors: (i) the proposed Transfer would result in more than two subleases of portions of the Premises being in effect at any one time during the Term; (ii) the net effective rent payable by the Transferee (adjusted on a rentable square foot basis) is less than the net effective rent then being quoted by Landlord for new leases in the Building for comparable size space for a comparable period of time; (iii) the proposed Transferee is an existing tenant of the Building or is negotiating with Landlord (or has negotiated with Landlord in the last six (6) months for space in the Building; (iv) the proposed Transferee is a governmental entity; (v) the portion of the Premises to be sublet or assigned is irregular in shape with inadequate means of ingress and egress; (vi) the use of the Premises by the Transferee (A) is not -21- permitted by the use provisions in Article 10 hereof, or (B) violates any exclusive use granted by Landlord to another tenant in the Building; (vii) the Transfer would likely result in significant increase in the use of the parking areas or Common Areas by the Transferee's employees or visitors, and/or significantly increase the demand upon utilities and services to be provided by Landlord to the Premises; (viii) the Transferee does not have the financial capability to fulfill the obligations imposed by the Transfer; (ix) the Transferee is not in Landlord's reasonable opinion of reputable or good character or consistent with Landlord's desired tenant mix; or (x) the Transferee is a real estate developer or landlord or is acting directly or inidirectly on behalf of a real estate developer or landlord. 11.6 Release. No Transfer shall release Tenant of Tenant's obligations ------- under this Lease or alter the primary lability of Tenant to pay the rent and to perform all other obligations to be performed by Tenant hereunder. If there is an Event of Default under this Lease, Landlord may thereafter require that any Transferee of Tenant remit directly to Landlord on a monthly basis, all monies due Tenant by said Transferee. However, the acceptance of Rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent by Landlord to one Transfer shall not be deemed consent to any subsequent Transfer. If an Event of Default occurs by any Transferee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such Transferee or successor. Landlord may consent to subsequent assignments of the Lease or sublettings or amendments or modifications to the Lease with assignees of Tenant, without notifying Tenant, or any successor of Tenant, and without obtaining its or their consent thereto and any such actions shall not relieve Tenant of liability under this Lease. 11.7 Administrative and Attorneys' Fees. If Tenant effects a Transfer or ---------------------------------- requests the consent of Landlord to any Transfer, then Tenant shall, upon demand, pay Landlord a non-refundable administrative fee of Five Hundred Dollars ($500.00), plus any consultants', engineers' and reasonable attorneys' fees incurred by Landlord in connection with such Transfer or request for consent. Landlord shall provide an estimate of the consultants', engineers' and reasonable attorneys' fees at the time of Tenant's request for consent. Acceptance of -22- the $500.00 administrative fee and reimbursement of Landlord's attorneys' and paralegal fees shall in no event obligate Landlord to consent to any proposed Transfer. 11.8 Material Inducement. Tenant understands, acknowledges and agrees that ------------------- (i) Landlord's option to terminate this Lease upon any proposed Transfer as provided in Section 11.3(b) above rather than approve the proposed Transfer, and (ii) Landlord's right to receive any excess consideration paid by a Transferee in connection with an approved Transfer as provided in Section 11.4(d) above, are a material inducement for Landlord's agreement to lease the Premises to Tenant upon the terms and conditions herein set forth. ARTICLE 12: MAINTENANCE AND REPAIR 12.1 Landlord's Obligation. Except for repairs which Tenant is required to --------------------- make pursuant to Section 12.2, Landlord shall keep and maintain in good repair and working order the Building, including the Common Area and the equipment within and serving the Premises and the Building (excluding Tenant's Property) that are required for the normal maintenance and operation of the Premises and the Building. In addition, Landlord shall assume responsibility for the maintenance of Tenant's cooling tower and emergency generator. The cost of such maintenance and repairs to the Building and said equipment shall be included in the Operating Expenses and paid by Tenant as provided in Article 7 herein. All work shall be performed in a first-class workmanlike manner. Tenant shall use its best efforts to immediately give Landlord written notice of any defect or need for repairs. After such notice, Landlord shall have a reasonable opportunity to repair or cure such defect. Landlord's liability with respect to any defects, repairs or maintenance for which Landlord is responsible under any of the provisions of this Lease shall be limited to the cost of such repairs or maintenance or the curing of such defect. 12.2 Tenant's Obligation. Tenant shall, at its own expense, maintain the ------------------- Premises and all of Tenant's Property in good, clean and safe condition, promptly making all necessary repairs and replacements.

If any insurance coverage carried by Landlord pursuant to this Article 17 or otherwise with respect to the Building or Land shall be canceled or reduced (or cancellation or reduction thereof shall be threatened) by reason of the use or occupancy of the Premises by Tenant or by anyone permitted by Tenant to be upon the Premises, and if Tenant fails to remedy such condition within five (5) days after delivery of written notice thereof, it shall be deemed an Event of Default under this Lease, without the benefit of any additional notice or cure period specified in Section 22.2 (ii) herein, and Landlord shall have all remedies provided in this Lease, at law or in equity, including, without limitation, the right (but not the obligation) to enter upon the Premises and attempt to remedy such condition at Tenant's sole cost and expense which will be Additional Rent when incurred by Landlord payable upon demand plus interest thereon at the Interest Rate accruing five (5) days after demand until paid.

If this Lease is terminated as the result of a casualty in accordance with Article 21 herein, except for Alterations or work designated by Landlord to be removed on or before the expiration or earlier termination of this Lease in accordance with Section 15.2 herein, the proceeds of said insurance attributable to the repair and/or replacement of any leasehold improvements, tenant improvements or Alterations performed by or on behalf of Tenant or by Landlord pursuant to the terms of the Work Agreement or this Lease shall be the property of the Landlord and paid to Landlord immediately after receipt of such proceeds by Tenant from its carrier, but no later than sixty (60) days after the date the Lease is terminated, together with interest thereon at the Interest Rate accruing five (5) days after demand until paid. 17.4 Additional Insurance. -------------------- (a) Tenant shall, at its sole cost and expense, procure and maintain business interruption insurance in an amount not less than the Base Rent due hereunder for the first Lease Year, which amount shall be revised from time to time upon the reasonable request of the Landlord or its Mortgagee. -30- (b) Tenant shall, at all times during the term hereof, maintain in effect workers' compensation insurance as required by applicable Legal Requirements. 17.5 Requirements of Insurance Coverage.

Tenant's insurance policies shall not include deductibles in excess of Five Thousand and 00/100 Dollars ($5,000.00). 17.6 Waiver of Subrogation. Each party hereby releases the other party --------------------- hereto from liability for any loss or damage to any building, structure or tangible personal property, or any resulting loss of income, or losses under worker's compensation laws and benefits, notwithstanding that such loss, damage or liability may arise out of the negligent or intentionally tortious act or omission of the other party or its Agents, if such loss or damage is covered by insurance, and insurance proceeds are actually received, benefitting the party suffering such loss or damage or was required to be covered by insurance pursuant to this Lease. Each party hereto shall require its insurer(s) to include in its insurance policies a waiver of subrogation clause (providing that such waiver of right of recovery against the other party shall not impair the effectiveness of such policy or the insured's ability to recover thereunder), and shall promptly notify the other in writing if such clause cannot be included in any such policy; if such waiver of subrogation clause shall not be available, then the foregoing waiver of right of recovery shall be void. -31- 17.7 Security. In the event that Landlord engages the services of a -------- professional security system for the Building, it is understood that such engagement shall in no way increase Landlord's liability for occurrences and/or consequences which such a system is designed to detect or avert and that Tenant shall look solely to its insurer as set out above for claims for damages or injury to any person or property. 17.8 Landlord's Insurance. Landlord shall procure and maintain throughout -------------------- the Term fire and extended coverage insurance on the Building in such coverage and amounts as reasonably determined by Landlord in its prudent management of the Building and as necessary to satisfy the requirements of Landlord's Mortgagee, if any. At Landlord's option, such insurance may be carried under any blanket or umbrella policies which Landlord has in force for other buildings and projects. In addition, at Landlord's option, Landlord may elect to self-insure all or any part of such required insurance coverage. Landlord may, but shall not be obligated to, carry any other form or forms of insurance as Landlord or the mortgagees or ground lessors of Landlord may reasonably determined is advisable. 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. 17.9 Coverage. Landlord makes no representation to Tenant that the limits -------- or forms of coverage specified above or approved by Landlord are adequate to insure Tenant's Property or Tenant's obligations or assumption of contractual liability under this Lease, and the limits of any insurance carried by Tenant shall not limit its duties and obligations under this Lease. ARTICLE 18: LANDLORD SERVICES AND UTILITIES 18.1 Ordinary Services to the Premises.

The foregoing services shall be furnished by Landlord and reimbursed by Tenant as part of Operating Expenses, provided, however, that Landlord shall be under no responsibility or liability for failure, defect or interruption in such services caused by Force Majeure, breakage, accident, strikes, repairs or for any other cause or causes beyond the control of Landlord, nor in any event for any indirect or consequential damages; and failure or omission on the part of Landlord to furnish such service shall not be construed as an eviction of Tenant, nor work an abatement of Rent, nor render Landlord liable in damages, nor release Tenant from prompt fulfillment of any of the covenants under this Lease. Landlord may comply with voluntary controls or guidelines promulgated pursuant to any Legal Requirements relating to the use or conservation of energy, water, gas, light, or electricity or the reduction of automobile or other emissions without creating any liability of Landlord to Tenant under this Lease. Landlord shall not be responsible if the normal operation of the Building air-conditioning system shall fail to provide conditioned air within comfortable temperatures levels (A) in any portions of the Premises which have a connected electrical load for all purposes (including lighting and power) or which have a human occupancy in excess of the average electrical load and human occupancy factors for which the Building air-conditioning system is designed, (B) because of Alterations made by or on behalf of Tenant, (C) in any portions of the Premises exposed to direct sunlight in which Tenant fails to keep the window treatments closed, or (D) because of the failure by Tenant or its Agents to use the HVAC system in the manner in which it was designed to be used.

If Tenant requires or requests ------------------------------------ that the services to be furnished by Landlord (except Building standard electricity and elevator service) be provided during periods in addition to the periods set forth in Section 18.1, then Tenant shall obtain Landlord's consent thereto by requesting such consent at least four (4) business hours in advance of the need for such service and, if such -33- consent is granted, shall pay upon demand Landlord's additional expenses resulting therefrom. Landlord may, from time to time during the Term, set a per hour charge for after-hours service which shall include the cost of utility, service, labor costs, administrative costs and a cost for depreciation of the equipment used to provide such after-hours service. 18.3 Utility Charges. All telephone, electricity, gas, heat and other --------------- utility service furnished to the Premises shall be paid for directly by Tenant except to the extent the cost of same is included within, and paid for by Tenant as part of, Operating Expenses. Landlord reserves the right separately to meter or monitor the utility services provided to the Premises. The cost of any such meter shall be born by the Tenant. Tenant shall reimburse Landlord for the cost of any excess utility usage in the Premises. Excess usage shall mean usage which exceeds one hundred ten percent (110%) (on a rentable square foot basis) during any billing period over the building standard usage (which shall mean the average per square foot usage of all office tenants in the Building during Normal Business Hours excluding the Tenant or any other tenants notified by Landlord of excessive utility consumption) during the same period as reasonably calculated by Landlord. Tenant shall pay for the excess consumption of electricity at the then-current price per kilowatt hour and price per unit of demand charged Landlord by the utility company plus a reasonable administrative cost which shall include service, labor costs, administrative costs and a cost for depreciation of the equipment used to provide such excess service.

Except where due to Landlord or its Agents' wanton or willful acts or omissions and as stated otherwise herein, any goods, automobiles, property or personal effects stored or placed by Tenant or its Agents in or about the Premises, the Building or the Common Area shall be at the sole risk of Tenant; Tenant hereby expressly waives its right to recover against Landlord and its Agents therefor. Tenant hereby waives any claim it might have against Landlord or its Agents for any consequential damages or business losses sustained by Tenant arising out of the loss or damage to any person or property of Tenant, or any interruption in the use of the Premises or the Common Area, for any reason. Tenant acknowledges its obligation to insure against such losses and damages. Tenant shall not have the right to offset or deduct any amount allegedly owed to Tenant pursuant to any claim against Landlord from any Rent or other sum payable to Landlord. Tenant's sole remedy for recovering upon such claim shall be to institute an independent action against Landlord. 19.2 Indemnity. Tenant shall indemnify, defend, protect and hold Landlord --------- and its Agents harmless from and against any and all damage, claim, liability, cost or expense (including, without limitation, reasonable attorneys' or other professionals' fees) of every kind and nature (including, without limitation, those arising from any injury or damage to any person, property or business) incurred by or claimed against Landlord or through Landlord by its Agents, directly or indirectly, as a result of, arising from or in connection with (i) Tenant's or its authorized Agents' use, occupancy, repair or maintenance of the Premises, the Building or the Common Area; (ii) an Event of Default by Tenant under any provisions of this Lease; or (iii) any act, omission or negligence of Tenant or its Agents, but in each instance, only to the extent such damage, claim, liability, cost or expense was not caused, in whole or in part, by the wanton or willful acts or omissions of Landlord or its Agents. 19.3 Limitation on Recourse. Notwithstanding anything contained in this ---------------------- Lease to the contrary, the obligations of Landlord under this Lease (including any actual or alleged breach or default by Landlord) do not constitute personal obligations of the individual partners, directors, officers, shareholders, trustees, advisors or agents of Landlord or Landlord's partners, and Tenant shall not seek recourse against the individual partners, directors, officers or shareholders, trustees, advisors or agents of Landlord or Landlord's partners, or any of their -35- personal assets for satisfaction of any liability with respect to this Lease. In addition, in consideration of the benefits accruing hereunder to Tenant and notwithstanding anything contained in this Lease to the contrary, Tenant hereby covenants and agrees for itself and all of its successors and assigns that the liability of Landlord for its obligations under this Lease (including any liability as a result of any actual or alleged failure, breach or default hereunder by Landlord), shall be limited solely to, and Tenant's and its successors' and assigns' sole and exclusive remedy shall be against Landlord's interest in the Building and Land and proceeds therefrom, and no other assets of Landlord. In the event that the original Landlord hereunder, or any successor owner of the Building, shall sell or convey the Building, all liabilities and obligations on the part of the original Landlord, or such successor owner, under this Lease occurring thereafter shall terminate as of the day of such sale, and thereupon all such liabilities and obligations shall be binding on the new owner. ARTICLE 20: RULES AND REGULATIONS 20.1 General. Tenant shall, and Tenant shall use its best efforts to cause ------- its Agents to, at all times abide by and observe the Rules and Regulations and any amendments thereto that may be promulgated from time to time by Landlord for the operation and maintenance of the Building and the Common Area and the Rules and Regulations shall be deemed to be covenants of the Lease to be performed and/or observed by Tenant. Nothing contained in this Lease shall be construed to impose upon Landlord any duty or obligation to enforce the Rules and Regulations, or the terms or provisions contained in any other lease, against any other tenant of the Building. Landlord shall not be liable to Tenant for any violation by any party of the Rules and Regulations or the terms of any other Building lease. If there is any inconsistency between this Lease and the Rules and Regulations, this Lease shall govern. Landlord reserves the right to amend and modify the Rules and Regulations as it deems necessary; provided, however that except to the extent such Rules and Regulations are imposed to comply with governmental mandates, future rules or regulations, or amendments of existing rules or regulations, shall not impose, directly or indirectly, on Tenant or any of its Agents any additional material cost or expense. -36- ARTICLE 21: DAMAGE AND CONDEMNATION 21.1 Damage to the Premises. If the Premises shall be damaged by fire or ---------------------- other cause without the fault or negligence of Tenant or its Agents. Landlord shall diligently and as soon as practicable after such damage occurs (taking into account the time necessary to effect a satisfactory settlement with any insurance company involved and any delays beyond the direct control of Landlord) repair such damage to the Premises (excluding the Tenant's Property) at the expense of Landlord; provided, however, that Landlord's obligation to repair such damage shall not exceed the proceeds of insurance available to Landlord (reduced by any proceeds retained pursuant to the rights of Mortgagee). Notwithstanding the foregoing, (i) if the Premises or the Building is damaged by fire or other cause to such an extent that, in Landlord's sole judgment, such judgment to be communicated to Tenant within sixty (60) days after the damage, the damage cannot be substantially repaired within one hundred twenty (120) days after the date of permit issuance necessary for the repair of such damage, then Landlord or Tenant within ninety (90) days from the date of such damage may terminate this Lease by written notice to the other, or (ii) if the Premises are damaged during the last Lease Year, then Landlord or Tenant within thirty (30) days from the date of such damage may terminate this Lease by written notice to the other. If either Landlord or Tenant terminates this Lease, the Rent shall be apportioned and paid to the date of such casualty. If neither Landlord nor Tenant so elects to terminate this Lease but the damage required to be repaired by Landlord is not repaired within one hundred twenty (120) days from the date of permit issuance to cause the repair of such damage (such 120-day period to be extended by the period of any delay outside the direct control of Landlord plus a reasonable period for a satisfactory settlement with any insurance company involved), Tenant, within thirty (30) days from the expiration of such 120-day period (as the same may be extended), may terminate this Lease by written notice to Landlord. During the period that Tenant is deprived of the use of the damaged portion of the Premises, and provided such damage is not the consequence of the fault or negligence of Tenant or its Agents, Base Rent and Tenant's Proportionate Share shall be reduced by the ratio that the rentable square footage of the Premises or square footage inaccessible due to such damaged bears to the total rentable square footage of the Premises before such damage. Notwithstanding anything herein to the contrary, Landlord shall not be required to rebuild, replace or repair any of the Tenant's Property, except for Alterations -37- or work designated by Landlord to be removed on or before the expiration or earlier termination of this Lease in accordance with Section 15.2 herein. In the event that neither party terminates this Lease as aforesaid, Tenant shall be required to repair or replace the Tenant's Property, except for Alterations or work designated by Landlord to be removed on or before the expiration or earlier termination of this Lease in accordance with Section 15.2 herein. 21.2 Condemnation. If the whole or a Substantial Part of the Premises or ------------ the Building shall be taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including, without limitation, sale under threat of such a taking), then the Term shall cease and terminate as of the date when title vests in such governmental or quasi-governmental authority, and Rent shall be prorated to the date when title vests in such governmental or quasi-governmental authority. If less than a Substantial Part of the Premises is taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including, without limitation, sale under threat of such a taking), all Rent shall be reduced by the ratio that the portion so taken bears to the rentable square footage of the Premises before such taking, effective as of the date when title vests in such governmental or quasi-governmental authority, and this Lease shall otherwise continue in full force and effect, provided, Tenant's use, visibility of, and access to the Premises are not materially affected thereby. Tenant shall have no claim against Landlord (or otherwise) as a result of such taking, and Tenant hereby agrees to make no claim against the condemning authority for any portion of the amount that may be awarded as compensation or damages as a result of such taking; provided, however, that Tenant may, to the extent allowed by law, claim an award for moving expenses and for the taking of any of Tenant's Property (other than its leasehold interest in the Premises) which does not, under the terms of this Lease, become the property of Landlord at the termination hereof, as long as such claim is separate and distinct from any claim of Landlord and does not diminish Landlord's award. Tenant hereby assigns to Landlord any right and interest it may have in any award for its leasehold interest in the Premises. -38- ARTICLE 22: DEFAULT 22.1 Events of Default. Each of the following shall constitute an Event of ----------------- Default: (i) Tenant fails to pay Rent within five (5) days after Tenant's receipt of written notice from Landlord; provided that no such notice shall be required if at least two such notices shall have been given during the same Lease Year; (ii) Tenant fails to observe or perform any other term, condition or covenant herein binding upon or obligating Tenant within its receipt of ten (10) business days written notice from Landlord, or, if said default is curable but shall reasonably require longer than ten (10) business days to cure, if Tenant shall fail to commence to cure said default within ten (10) business days after receipt of notice thereof and/or fail continuously to prosecute the curing of the same to completion with due diligence, and in any event within such period of time as will prevent Landlord from being subjected to the risk of criminal liability or termination of any foreclosure of any mortgage; (iii) Tenant or any Guarantor makes or consents to a general assignment for the benefit of creditors or a common law composition of creditors, or a receiver of the Premises or all or substantially all of Tenant's or Guarantor's assets is appointed; (iv) a Transfer in violation of Article 11 herein; or (v) the failure by Tenant to timely perform any of those covenants described in Section 17.1 of this Lease. 22.2 Landlord's Remedies. Upon the occurrence of an Event of Default, ------------------- Landlord, at its option, without further notice or demand to Tenant, may in addition to all other rights and remedies provided in this Lease, at law or in equity: (a) Terminate this Lease and Tenant's right of possession of the Premises. If Landlord elects to terminate the Lease, every obligation of the parties shall cease as of the date of such termination, except for those obligations of the Tenant that survive the expiration or earlier termination of the Lease and as provided in Section 22.3. (b) Terminate Tenant's right of possession of the Premises without terminating this Lease, in which event Landlord may, but shall not be obligated to, relet the Premises, or any part thereof, for the account of Tenant, for such rent and term and upon such other conditions as are acceptable to Landlord in its sole and absolute discretion. For purposes of such reletting, Landlord is authorized to redecorate, repair, alter and improve the Premises to the extent necessary in Landlord's sole discretion. -39- (c) Re-enter and repossess the Premises and remove all persons and effects therefrom, by summary proceeding, ejectment or other legal action or by using such force as may be necessary. Landlord shall have no liability by reason of any such re-entry, repossession or removal. Notwithstanding anything to the contrary contained in this Lease, Landlord hereby agrees to use reasonable efforts to mitigate damages; provided, however, that Landlord, in attempting to lease the Premises shall not be obligated to give preference to the Premises over any other available space in the Building (as stated in Section 22.3 below). 22.3 Tenant's Liability for Damages. If Landlord terminates this Lease or ------------------------------ the Tenant's right to possession pursuant to Section 22.2, Tenant shall remain liable (in addition to accrued liabilities) to the extent legally permissible for (i) the sum of (A) all Base Rent and Additional Rent provided for in this Lease until the date this Lease would have expired had such termination not occurred, and (B) any and all costs, expenses and damages incurred by Landlord in terminating the Lease, reentering the Premises, repossessing the same, making good any default of Tenant, painting, altering or dividing the Premises, combining the same with any adjacent space for any new tenants, putting the same in proper repair, reletting the same (including any and all rental concessions to new tenants, repairs, Alterations, attorneys' fees and disbursements and brokerage fees and commissions), 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 proceeds of any reletting. Tenant agrees to pay to Landlord the difference between items (i) and (ii) above with respect to each month during the Term, at the end of such month. Any suit brought by Landlord to enforce collection of such difference for any one month shall not prejudice Landlord's right to enforce the collection of any difference for any subsequent month. In addition to the foregoing, Tenant shall pay to Landlord such sums as the court which has jurisdiction thereover may adjudge reasonable as attorneys' fees with respect to any successful lawsuit or action instituted by Landlord to enforce the provisions of this Lease. Landlord shall have the right, at its sole option, to relet the whole or any part of the Premises for the whole of the unexpired 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 -40- sole but good faith discretion, may deem advisable. To the extent that Landlord attempts to relet the Premises, Landlord shall be under no obligation to lease all or any portion of the Premises before any other space in the Building is fully leased by Landlord and that if at the time of any reletting of the Premises there exists other reasonably comparable space in the Building available for leasing, then the Premises shall be deemed the last space rented, even though the Premises may be relet prior to the date such other reasonable comparable space is leased. Tenant's liability as aforesaid shall survive the institution of summary proceedings and the issuance of any warrant thereunder. Upon the occurrence of an Event of Default, Landlord may recover from Tenant the value and/or cost of all concessions to Tenant under this Lease. 22.4 Liquidated Damages. If Landlord terminates this Lease pursuant to ------------------ Section 22.2, Landlord shall have the right, at any time, at its option, to require Tenant to pay to Landlord, on demand, as liquidated and agreed final damages in lieu of Tenant's liability under Section 22.3 (other than for Tenant's liability for concessions, attorneys' and brokerage fees), an amount equal to the difference, discounted to the date of such demand at an annual rate of interest equal to the then-current yield on actively traded U.S. Treasury bonds with 10-year maturities, as published in the Federal Reserve Statistical Release for the week prior to the date of such termination, between (i) the Base Rent and Additional Rent, computed on the basis of the then-current annual rate of Base Rent and Additional Rent and all fixed and determinable increases in Base Rent, which would have been payable from the date of such demand to the date when this Lease would have expired, if it had not be terminated, and (ii) the then fair rental value of the Premises for the same period as determined by the Landlord. Upon payment of such liquidated and agreed final damages, Tenant shall be released from all further liability under this Lease with respect to the period after the date of such demand except for those obligations of the Tenant that survive the expiration or earlier termination of the Lease. If, after the Event of Default giving rise to the termination of this Lease, but before presentation of proof of such liquidated damages, the Premises, or any part thereof, shall be relet by Landlord for a term of one year or more, the amount of rent reserved upon such reletting shall be deemed to be the fair rental value for the part of the Premises so relet during the term of such reletting. -41- 22.5 Rights Upon Possession. If Landlord takes possession pursuant to this ---------------------- Article, with or without terminating this Lease, Landlord may, at its option, enter into the Premises, remove Tenant's Alterations, signs, personal property, equipment and other evidences of tenancy, and store them at Tenant's risk and expense or dispose of them as Landlord may see fit, and take and hold possession of the Premises: provided, however, that if Landlord elects to take possession only without terminating this Lease, such entry and possession shall not terminate this Lease or release Tenant or any Guarantor, in whole or in part, from the obligation to pay the Rent reserved hereunder for the full Term or from any other obligation under this Lease or any guaranty thereof. 22.6 No Waiver. If Landlord shall institute proceedings against Tenant and --------- a compromise or settlement thereof shall be made, the same shall not constitute a waiver of any other covenant, condition or agreement herein contained, nor of any of Landlord's rights hereunder. No waiver by Landlord of any breach shall operate as a waiver of such covenant, condition or agreement, or operate as a waiver of such covenant, condition or agreement itself, or of any subsequent breach thereof. No payment of Rent by Tenant or acceptance of Rent by Landlord shall operate as a waiver of any breach or default by Tenant under this Lease. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installment of Rent herein stipulated shall be deemed to be other than a payment on account of the earliest unpaid Rent, nor shall any endorsement or statement on any check or communication accompanying a check for the payment of Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such Rent or to pursue any other remedy provided in this Lease. No re-entry by Landlord, and no acceptance by Landlord of keys from Tenant, shall be considered an acceptance of a surrender of the Lease. 22.7 Right of Landlord to Cure Tenant's Default. If an Event of Default ------------------------------------------ shall occur, then Landlord may (but shall not be obligated to) make such payment or do such act to cure the Event of Default, and charge the amount of the expense thereof, together with interest thereon at the Interest Rate, to Tenant. Such payment shall be due and payable upon demand; however, the making of such payment or the taking of such action by Landlord shall not be deemed to cure the Event of Default or to stop Landlord from the pursuit of any remedy to -42- which Landlord would otherwise be entitled. Any such payment made by Landlord on Tenant's behalf shall bear interest until paid at the Interest Rate. 22.8 Late Payment. If Tenant fails to pay any Rent within five (5) days ------------ after such Rent becomes due and payable, Tenant shall pay to Landlord a late charge of five percent (5%) of the amount of such overdue Rent. In addition, any such late Rent payment shall bear interest from the date such Rent became due and payable to the date of payment thereof by Tenant at the Interest Rate. Such late charge and interest shall be due and payable within two (2) days after written demand from Landlord. 22.9 Landlord's Lien. As security for the performance of Tenant's --------------- obligations, Tenant grants to Landlord a lien upon and a security interest in Tenant's goods both existing or hereafter acquired located in the Premises. Such lien shall be in addition to Landlord's rights of distraint, if any. Within twenty (20) days after request, Tenant shall execute, acknowledge and deliver to Landlord a financing statement and any other document submitted to Tenant in form reasonably acceptable to Tenant evidencing or establishing such lien and security interest. During any period that an Event of Default exists hereunder, Tenant shall not sell, transfer or remove from the Premises all or any portion of Tenant's goods except to repair, exchange, or replace such items of Tenant's goods comprised of tangible personal property, furniture, and business trade fixtures and equipment; provided such repair, exchange, or replacement of such designated items is of equal or greater value. Landlord hereby agrees that its lien upon Tenant's goods comprised of tangible personal property, furniture, and business trade fixtures and equipment shall be automatically subordinated to any purchase money security interest or to the line of any institutional lender of Tenant, if required by such lender. In confirmation of such subordination upon the reasonable request of Tenant, Landlord shall at Tenant's expense, execute a commercially reasonable and customary subordination instrument in form acceptable to Landlord in its reasonable discretion. 22.10 [Intentionally Deleted] ARTICLE 23: BANKRUPTCY 23.1 Event of Bankruptcy. An "Event of bankruptcy" is: the occurrence, with ------------------- respect to Tenant, of any of the following: (i) Tenant's becoming insolvent, as that term is defined in Title 11 of the United States Code (the "Bankruptcy Code"), or under the insolvency law of any state (the "Insolvency Laws"); (ii) -43- appointment of a receiver or custodian for any property of Tenant, or the institution of a foreclosure or attachment action upon any property of Tenant; (iii) filing of a voluntary petition by Tenant under the provisions of the Bankruptcy Code or Insolvency Laws; (iv) filing of an involuntary petition against Tenant as the subject debtor under the Bankruptcy Code or insolvency Laws, which either (A) is not dismissed within sixty (60) days after filing, or (B) results in the issuance of an order for relief against the debtor; or (v) Tenant's making or consenting to an assignment for the benefit of creditors or a composition of creditors. 23.2 Remedies. Upon occurrence of an Event of Bankruptcy, Landlord shall -------- have all rights and remedies available pursuant to Article 22; provided, however, that while a case (the "Case") in which Tenant is the subject debtor under the Bankruptcy Code is pending, Landlord's right to terminate this Lease shall be subject, to the extent required by the Bankruptcy Code, to any rights of Tenant or its trustee in bankruptcy (collectively, "Trustee") to assume or assign this Lease pursuant to the Bankruptcy Code. Trustee shall not have the right to assume or assign this Lease unless Trustee promptly: (i) cures all defaults under this Lease; (ii) compensates Landlord for damages incurred as a result of such defaults; (iii) provides adequate assurance of future performance on the part of Tenant or Tenant's assignee; (iv) complies with the other requirements of this Article; and (v) complies with all other requirements of the Bankruptcy Code. If Trustee fails to assume or assign this Lease in accordance with the requirements of the Bankruptcy Code within sixty (60) days after entry of an order for relief then Trustee shall be deemed to have rejected this Lease. Adequate assurance of future performance shall require that the following minimum criteria be met: (A) Tenant's gross receipts in the ordinary course of business during the thirty (30) days preceding the Case must be greater than ten (10) times the next monthly installment of the Base Rent and additional rent; (B) both the average and median of Tenant's monthly gross receipts in the ordinary course of business during the seven (7) months preceding the Case must be greater than ten (10) times the next monthly installment of the Base Rent and additional rent; (C) Trustee must pay its estimated pro-rata share of the cost of all services performed or provided by Landlord (whether directly or through agents or contractors and whether or not previously included as part of the Base Rent) in advance of the performance or provision of such services; (D) Trustee must agree that Tenant's business shall be conducted in a first-class manner, and that no liquidating sale, auction or other non-first-class business operation -44- shall be conducted in the Premises; (E) Trustee must agree that the use of the Premises as stated in this Lease shall remain unchanged and that no prohibited use shall be permitted: (F) Trustee must agree that the assumption or assignment of this Lease shall not violate or affect the rights of other tenants in the Building and the complex or area in which the Building is located; (G) Trustee must pay at the time the next monthly installment of the Base Rent is due, in addition to such installment, an amount equal to the monthly installments of the Base Rent and additional rent due for the next six (6) months thereafter, such amount to be held as a security deposit; (H) Trustee must agree to pay, at any time Landlord draws on such security deposit, the amount necessary to restore such security deposit to its original amount; and (I) all assurances of future performance specified in the Bankruptcy Code must be provided. If Trustee shall propose to assume and assign this Lease to any person who shall have made a bona fide offer to accept an assignment of this Lease on terms acceptable to Trustee, then notice of such proposed assignment shall be given to Landlord by Trustee no later than twenty (20) days after receipt by Trustee of such offer, but in any event no later than ten (10) days prior to the date that Trustee shall make application to the court of competent jurisdiction for approval to assume this Lease and enter into such assignment, and Landlord shall thereupon have the option, to be exercised by notice to Trustee given at any time prior to the date of such application, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the offer made by such person, less any brokerage commissions which may be payable out of the consideration to be paid by such person for the assignment of this Lease. ARTICLE 24: MORTGAGES 24.1 Subordination. ------------- (a) This Lease and Tenant's interest hereunder shall be, at the option of Mortgagee's collateral agent, subordinate to or superior to the lien of any Mortgage made by Landlord. If at any time or from time to time during the Term, a Mortgagee or prospective Mortgagee, or a collateral agent therefor, requests that this Lease be subject and subordinate to its Mortgage, 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) business days after receipt of a written request therefor from Landlord, it will, -45- 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 Premises to the lien of such Mortgage. 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) business days after receipt of a request therefor from Landlord, execute, acknowledge and deliver any and all documents and instruments confirming the priority of this Lease. 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. Notwithstanding the foregoing to the contrary, with respect to each Mortgage that may encumber the Building on or after the Commencement Date, Landlord agrees, upon receipt of written request from Tenant, to use reasonable efforts to obtain on behalf of Tenant a subordination, nondisturbance and attornment agreement in the usual form of such Mortgagee, such form for the current Mortgagee attached hereto as Exhibit E. Tenant shall bear all reasonable --------- and customary costs and expenses of such Mortgagee in connection with obtaining such subordination, nondisturbance and attornment agreement(s), if any. (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 located, or both, and to all renewals, modifications, consolidations, replacements and extensions thereof. Tenant agrees that, within ten (10) business days after receipt of 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 Premises to such ground or underlying lease. 24.2 Mortgagee Protection. Tenant agrees to give any Mortgagee or -------------------- Mortgagee's collateral agent, by certified mail, return receipt requested, a copy of any notice of default served upon Landlord, provided that before such notice Tenant has been notified in writing of the address of such Mortgagee or Mortgagee's -46- collateral agent. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then the Mortgagee or Mortgagee's collateral agent shall have an additional thirty (30) days within which to cure such default; provided, however, that if such default cannot be reasonably cured within that time, then such Mortgagee or Mortgagee's collateral agent shall have such additional time as may be necessary to cure such default so long as Mortgagee has commenced and is diligently pursuing the remedies necessary to cure such default (including, without limitation, the commencement of foreclosure proceedings, if necessary), in which event Tenant shall not exercise any remedies for default while such remedies are being so diligently pursued. In the event of the sale of the Land or the Building, by foreclosure or deed in lieu thereof, the Mortgagee or purchaser at such sale shall be responsible for the return of the Security Deposit only to the extent that such Mortgagee or purchaser actually received the Security Deposit. 24.3 Modification Due to Financing. If, in connection with obtaining ----------------------------- construction or permanent financing for the Premises, the Building or the Land, any lender (or Mortgagee) shall request reasonable modifications of this Lease as a condition to such financing, Tenant shall promptly execute a modification of this Lease, provided such modifications do not increase the financial obligations of Tenant hereunder or adversely affect the leasehold interest hereby created or Tenant's reasonable use and enjoyment of the Premises. Tenant and any Guarantor shall each, prior to execution and throughout the Term, upon request from time to time, provide such financial information and documentation about itself to Landlord or Mortgagee as may be requested. 24.4 Attornment. In the event of (i) a transfer of Landlord's interest in ---------- the Premises, (ii) the termination of any ground or underlying lease of the Building or the land on which it is constructed, or both, or (iii) 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, at the request of Landlord or Landlord's successor in interest, 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 lessor, transferee or purchaser, as "Landlord," and Tenant, as -47- "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 its succession to title, nor be subject to any offset, defense or counterclaim accruing prior to such lease termination or prior to such succession to title, nor be bound by any payment of Base Rent or Additional Rent prior to such lease termination or prior to such succession to title for more than one month in advance. Tenant shall, upon request by Landlord or the transferee or purchaser of Landlord's interest or the lessor under the termination ground or underlying lease, as the case may be, execute and deliver an instrument or instruments confirming the foregoing provisions of this Section. ARTICLE 25: SURRENDER AND HOLDING OVER 25.1 Surrender of the Premises. Tenant shall peaceably surrender the ------------------------- Premises to Landlord on the Expiration Date or earlier termination of this Lease, in broom-clean condition and in as good condition as when Tenant took possession, including, without limitation, the repair of any damage to the Premises caused by the removal of any of Tenant's Property pursuant to Section 15.2, except for reasonable wear and tear and loss by fire or other casualty not caused by Tenant or its Agents. If, for any reason, Tenant fails to surrender the Premises on the expiration or earlier termination of this Lease with such removal and repair obligations completed, then, in addition to the provisions of Section 25.2 herein and Landlord's rights and remedies under Article 22 and the other provisions of this Lease, Tenant shall indemnify, defend (by counsel reasonably approved in writing by Landlord) and hold Landlord harmless from and against any and all claims, judgments, suits, causes of action, damages, losses, liabilities and expenses (including reasonable attorneys' fees and court costs) resulting from such failure to surrender, including, without limitation, any claim made by any succeeding tenant based thereon. The foregoing indemnity shall survive the expiration or earlier termination of this Lease. 25.2 Holding Over. In the event that Tenant shall not immediately surrender ------------ the Premises to Landlord on the Expiration Date or earlier termination of this Lease, Tenant shall be deemed to be a month to month tenant upon all of the terms and provisions of this Lease, except the monthly Base Rent shall be termination equal to the greater of: (a) one hundred fifty percent (150%) of the Base Rent and Additional Rent applicable to the Premises immediately prior to the date of such expiration or earlier termination; or (b) two hundred percent (200%) of the prevailing market rate excluding any rental or other concessions (as reasonably -48- determined by Landlord) for the Premises in effect on the date of such expiration or earlier termination. Acceptance by Landlord of rent after such expiration or earlier termination shall not constitute a consent to a hold over hereunder or result in an extension of this Lease. Tenant shall pay an entire month's Rent calculated in accordance with this Section 25.2 for any portion of a month it holds over and remains in possession of the Premises pursuant to this Section. ARTICLE 26: QUIET ENJOYMENT 26.1 General. Landlord covenants that if Tenant shall pay Rent and perform ------- all of the terms and conditions of this Lease to be performed by Tenant, Tenant shall during the Term peaceably and quietly occupy and enjoy possession of the Premises without molestation or hindrance by Landlord or any party claiming through or under Landlord, subject to the provisions of this Lease and any Mortgage to which this Lease is subordinate and easements, conditions and restrictions of record affecting the Land. ARTICLE 27: TENANT'S COVENANTS REGARDING HAZARDOUS MATERIALS 27.1 Definition.

Tenant shall indemnify, defend and hold Landlord harmless from and against any and all actions (including, without limitation, remedial or enforce- -49- ment actions of any kind, administrative or judicial proceedings, and orders or judgments arising out of or resulting therefrom), costs, claims, damages (including, without limitation, punitive damages), expenses (including, without limitation, attorneys', consultants' and experts' fees, court costs and amounts paid in settlement of any claims or actions), fines, forfeitures or other civil, administrative or criminal penalties, injunctive or other relief (whether or not based upon personal or bodily injury, property damage, or contamination of, or adverse effects upon, the environment, water tables or natural resources), liabilities or losses arising from a breach of this prohibition by Tenant or its Agents. 27.3 Notice. In the event that Hazardous Materials are discovered upon, in, ------ or under the Premises, the Building or the Land, and applicable Legal Requirements require the removal of such Hazardous Materials, Tenant shall be responsible for removing those Hazardous Materials arising out of or related to the use or occupancy of the Premises by Tenant or its Agents. Notwithstanding the foregoing, Tenant shall not take any remedial action in or about the Premises, the Building or the Land without first notifying Landlord of Tenant's intention to do so and affording Landlord the opportunity to protect Landlord's interest with respect thereto.

The respective rights and obligations of Landlord and Tenant -------- under this Article 27 shall survive the expiration or earlier termination of this Lease. ARTICLE 28: MISCELLANEOUS 28.1 No Representations by Landlord. Tenant acknowledges that neither ------------------------------ Landlord or its Agents nor any broker has made any representation or promise with respect to the Premises, the Building, the Land or the Common Area, except as herein expressly set forth, and no rights, privileges, easements or licenses are acquired by Tenant except as herein expressly set forth. Tenant, by taking possession of the Premises shall accept the Premises and the Building "AS IS," and such taking of possession shall be conclusive evidence that the Premises and the Building are in good and satisfactory condition at the time of such taking of possession. 28.2 No Partnership. Nothing contained in this Lease shall be deemed or -------------- construed to create a partnership or joint venture of or between Landlord and Tenant, or to create any other relationship between Landlord and Tenant other than that of landlord and tenant. 28.3 Brokers.

The ten percent (10%) retainage shall be disbursed to Tenant thirty (30) days after substantial completion of Tenant's Work; provided, that in no event shall the retainage be disbursed to Tenant until such time as punch list items have been completed or corrected.

Landlord shall notify Tenant in writing (or via telecopy) as to whether it approves or disapproves a change(s) in the Plans within five (5) business days of Landlord's receipt of notification of such change. Notwithstanding the foregoing, Tenant shall not be required to obtain Landlord's approval for changes which are mandated during field inspection by a governmental entity, provided that such changes do not in any way affect the Base Building systems or the Common Areas or the appearance of either of the foregoing.

PRELIMINARY STATEMENT OF FACTS: A. Pursuant to a deed of trust, assignment of leases and rents, security agreement and fixture filing dated as of December 2, 1996 among Landlord and other mortgagors, Gary G. Peterson and James C. Brincefield, as trustees, either of whom may act, and the Mortgagee, recorded in, among other offices, the Clerk's Office of the Circuit Court of the City of Alexandria, Virginia, in Deed Book 1588 at page 1085 (as the same may be extended, renewed, supplemented or modified, the "Mortgage"), Landlord conveyed to the trustees named therein certain real estate and other property, including the real estate described in Exhibit A attached hereto (the "Mortgaged Property"), in trust to secure the --------- payment of a principal indebtedness in the aggregate amount of up to $359,480,000 as may be outstanding from time to time (the "Loan") in accordance with a loan agreement dated as of December 2, 1996 among Goldman Sachs Mortgage Company, as agent and as one of the Lenders, RF&P Corporation, as borrower, Main Street Mortgage Company, as servicer, LaSalle National Bank, as collateral agent for the Lenders, and the other Lenders from time to time party thereto (as the same may be extended, renewed, supplemented or modified, the "Loan Agreement").

C. The Loan Agreement requires that Tenant subordinate the Lease and its interest in the Premises to the lien of the Mortgage. NOW, THEREFORE, in consideration of the sum of One and 00/100 Dollar ($1.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by each party, it is agreed as follows: 1. SUBORDINATION. Subject to the provisions of this Agreement, Tenant ------------- hereby agrees that the Lease and the rights of Tenant in and to the Premises are subject and subordinate to the Mortgage, and to all amendments, supplements, modifications, renewals and extensions thereof, as fully and with the same effect as if the Mortgage had been duly executed, acknowledged and recorded prior to the execution of the Lease and delivery of possession of the Premises to Tenant; provided, however, that Mortgagee agrees and consents to the terms and provisions of the Lease. 2. NON-DISTURBANCE. If the interest of Landlord in the Premises shall be --------------- transferred by reason of foreclosure or other proceedings brought by Mortgagee under the Mortgage, including a deed in lieu of foreclosure (a "Transfer"), and if Tenant is not then in default under the Lease (beyond any applicable grace or cure periods), Mortgagee agrees that Tenant's rights and privileges under the Lease, and its possession of the 1 Premises, shall not be terminated, diminished or interfered with by Mortgagee in the exercise of any of Mortgagee's rights under the Mortgage. Mortgagee agrees not to join Tenant as a party defendant in any action or proceeding foreclosing the Mortgage unless such joinder is necessary to foreclose the Mortgage and then only for such purpose and not for the purpose of terminating the Lease. 3. ATTORNMENT. Upon the occurrence of a Transfer, Tenant shall be bound to ---------- the successor to Landlord's interest (hereinafter referred to as "Owner") under all of the terms, covenants, and conditions of the Lease for the balance of the term thereof remaining and any extensions or renewals thereof which may be effected in accordance with any option therefor in the Lease, and Tenant does hereby attorn to Owner as its landlord, said attornment to be effective and self-operative immediately without the execution of any further instruments on the part of either Tenant or Owner. However, at the request of Owner, Tenant will execute an instrument confirming such attornment. From and after such attornment, Owner shall be bound to Tenant under all of the terms, covenants, and conditions of the Lease as a direct indenture of Lease with the same force and effect as if originally entered into between Tenant and Owner; provided, however, that Tenant shall be under no obligation to pay rent to Owner until Tenant receives written notice from the Owner that Owner has succeeded to the interest of Landlord under the Lease, in which case Landlord agrees to indemnify, defend, protect and hold Tenant harmless from any liability it may suffer as a result of compliance with Owner's written instructions to pay rent. 4. MORTGAGEE'S RIGHT TO CURE LEASE DEFAULTS. In the event of a default by ---------------------------------------- Landlord or other occurrence under the Lease that would give rise to an offset against rent payable pursuant to the Lease, Tenant will give Mortgagee notice of such default or occurrence pursuant to the terms of Section 11 of this Agreement and will give Mortgagee such time as is provided to the Landlord under the Lease to cure such default or rectify such occurrence. It is understood that the time period available to Mortgagee to cure such default may run concurrently with the time period available to Landlord to cure such default. Tenant agrees that notwithstanding any provision of the Lease to the contrary. it will not be entitled to cancel the Lease, or to abate or offset against the rent, or to exercise any other right or remedy until Mortgagee has been given notice of default and an opportunity to cure the same as provided herein. 5. OWNER NOT BOUND BY CERTAIN ACTS OF LANDLORD. Following any Transfer of ------------------------------------------- the Premises, Owner shall not be: (a) either (i) personally liable for any of the obligations of the Landlord under the Lease (whether such obligations arose prior to or after the Transfer) and Tenant shall look solely to the interest of Owner, its successors and assigns, in the Mortgaged Property for the satisfaction of each and every remedy of Tenant in the event of default by Landlord under the Lease; or (ii) liable for any act or omission of any prior landlord (including Landlord) unless such act or omission of a prior landlord is of a continuing nature and Mortgagee had notice of such act or omission prior to the Transfer; provided, however, that the foregoing shall not be enforced or construed to, or limit the Tenant's right to obtain injunctive relief regarding any term. covenant or condition in the Lease; (b) liable for either prepaid rent or additional rent for more than one (I) month in advance or any security deposit paid and not delivered or credited to Mortgagee; or (c) bound by any amendment or modification of the Lease made without its consent; .provided, however, that Mortgagee agrees it shall not unreasonably delay or withhold its consent unless such amendment either materially increases Landlord's obligations or materially decreases Landlord's rights under the Lease. 6. ASSIGNMENT OF LEASE. Under the Mortgage, Landlord has assigned its ------------------- interest in the rents and payments due under the Lease to Mortgagee as security for repayment of the Loan. If in the future there is a default by Landlord in the performance and observance of the terms of the Mortgage, Mortgagee may, 2 at its option, require that all rents and other payments due under the Lease be paid directly to Mortgagee. Upon written notification by Mortgagee to Tenant demanding such rent payments be made to Mortgagee, Landlord hereby authorizes and directs Tenant, and Tenant hereby agrees to pay Mortgagee, any payments due under the terms of the Lease and Landlord shall indemnify and hold Tenant harmless from any liability or claim (including reasonable attorneys' fees) which may be asserted against Tenant as a result of Tenant's rent payment to Mortgagee or other sums due under the Lease. The assignment of rents under the Mortgage does not diminish any obligations of Landlord under the Lease or impose any such obligations on Mortgagee. 7. AMENDMENT.
