Further, in the event Tenant is unable to obtain the agreement of Diplomat to surrender the lot during the term of the Diplomat Lease, then if either the Diplomat lease is terminated before October 31, 2003, or upon termination of such lease as of October 31, 2003, Tenant shall also be entitled to lease the lot at 95% of the then prevailing market rates for surface parking lot use (recognizing a 25 space lot with a location within a comparable area having similar access to main streets as the particular lot) . In the event the parties are unable to agree upon market rates for the parking lot to be payable for the duration of the term hereof, by either (x) December 31, 2003, (in the case of a determination made as of October 31, 2003) or (y) within ninety (90) days following an earlier termination of the Diplomat Lease, then in either such instance the three (3) broker method shall be used.

The third broker shall be selected within fifteen (15) days after both of the first two (2) brokers have been selected. Within fifteen (15) days after the third broker has been selected all of the brokers shall meet to attempt to agree upon 95% of the then prevailing market rate for use of the lot as a surface parking lot, (recognizing a 25 space lot with a location within a comparable area having similar access to main streets as the particular lot) taking into consideration its "as-is" condition. If they are unable to reach agreement, they shall within said fifteen (15) day period submit in writing the prevailing market rate they deem appropriate and the prevailing market terms shall be the amount which is the mean between the two (2) closest amounts determined by two (2) of the brokers. Each of the parties shall pay for the costs of the services of the broker selected by it and the costs of the third broker shall be divided equally between the Landlord and Tenant. It is understood and agreed by the parties that the determination of the brokers shall be binding upon the parties; unless Tenant elects within thirty (30) days of written notice to Tenant of such determination to terminate its exercise of its rights hereunder on a prospective basis, such termination to be effective on the date specified by Tenant in its notice, but in no event later than ninety (90) days following the date of Tenant's election. 1.85 SECURITY DEPOSIT None 1.9 STANDARD BUILDING OPERATING DAYS AND HOURS 8:00 a.m. to 6:00 p.m., Monday through Friday 9:00 a.m. to 12:00 p.m., Saturday 1.10 USE OF PREMISES General office use in keeping with the quality and nature of comparable office buildings and/or any lawful use or activity in connection with the provision of telecommunications and/or internet services which shall include without limitation the installation, operation, maintenance and replacement of communications and switch equipment and facilities and various computer facilities.

(iii) If during the Base Year, the Building's occupancy level is less than ninety-five percent for the entire Base Year, or if the Building's occupancy level is less than 95% for six (6) months or more during any Fiscal Year other than the Base Year, or if all land and improvements upon which Operating Expenses are calculated or may be calculated pursuant to Subsection 2.2(b)(i) above were not fully complete and operational, or if any tenant is separately paying for services or utilities furnished to its premises or is provided with fewer services than customarily provided for tenants of general office space in the Building, then both (x) Operating Expenses accrued during such Base Year shall be adjusted to reflect the "Gross-Up" (defined below), and (y) such Operating Expenses accrued during such Fiscal Year or portion thereof (other than the Base Year) may be adjusted, at Landlord's sole option, to reflect the Gross-Up. For purposes hereof, the "Gross-Up" shall be defined as the adjustment to actual Operating Expenses necessary so as to reflect all additional expenses, as reasonably estimated by Landlord applying standard accounting procedures, so that both (x) in the case of the Base Year, the Operating Expenses equal the amount which would have been incurred by Landlord had the Building been fully used and occupied by tenants in at least 95% of all rentable area within the Building during the entire Base Year and (y) in the case of any Fiscal Year, other than the Base Year, the Tenant's share of Operating Expenses is the amount which would have been incurred by Tenant if the Building were fully occupied by tenants occupying at least 95% of all rentable area within the Building and all land and improvements upon which Operating Expenses are calculated or may be calculated pursuant to Subsection 2.2(b)(i) above were fully complete and operational during the entire such Fiscal Year using services and utilities customarily provided for general office use. For example, if the occupancy rate for the Building during at least six (6) months of a Fiscal Year is seventy percent (70%), and if the janitorial contractor charges $1.00 per square foot of occupied rentable area per year, and if the Building contains 100,000 square feet of rentable area, and if Landlord estimates that the Operating Expenses that would have been paid if the Building had been ninety-five percent (95%) occupied by tenants, using such customary janitorial services during such year, would have been $95,000, then for purposes of determining the increase in Operating Expenses payable during such Fiscal Year by Tenant, the Operating Expenses for such Fiscal Year shall be deemed to equal the actual Operating Expenses incurred by Landlord (without inclusion of the amount paid for the janitorial contractor charges) plus $95,000. <PAGE> 2.3 Additional Rent Estimates and Adjustments. ------------------------------------------ (a) Initial Additional Rent Adjustments. Landlord at its option may submit ------------------------------------ to Tenant prior to the date set forth in Section 1.5 a statement of Landlord's reasonable estimate of the increases described in Sections 2.2(a) and (b) above, together with the amount of Tenant's Additional Rent which is estimated to result from such increases, in which event Tenant shall pay such estimated Additional Rent to Landlord in equal monthly installments beginning on the date set forth in Section 1.5, on the dates and in the manner required for the payment of Tenant's monthly installments of Base Annual Rent. In the alternative, as soon as practicable after the end of the calendar year in which Tenant's obligation to pay Additional Rent pursuant to Sections 2.2(a) and (b) commences, Landlord may submit a lump sum statement to Tenant of the actual increases in Real Estate Taxes and/or Operating Expenses, if any, which were paid during the Fiscal Year which ended during such calendar year over the Real Estate Taxes and Operating Expenses which were paid during the Base Year, all as prorated based upon that portion of the Fiscal Year falling within the initial partial year of the Lease Term, and Tenant shall pay its pro rata share as Additional Rent on the date and in the manner required for the next monthly installment of Base Annual Rent due after submission of Landlord's statement. (b) Annual Budget. Subsequent to the calendar year in which Tenant's -------------- obligation to pay each component of Additional Rent pursuant to Section 2.2 commences, Tenant shall thereafter pay each such component of Additional Rent in twelve equal monthly installments based upon Landlord's estimates. In order to provide for the current monthly payment of each component of Additional Rent described herein, Landlord shall submit to Tenant a statement of Landlord's reasonable estimate of the increases described in Section 2.2 above, together with the amount of Tenant's Additional Rent which is estimated to result from such increases. Tenant agrees to pay each such estimated component of Additional Rent to Landlord in twelve equal installments beginning on January 1, on the dates and in the manner required for the payment of Tenant's monthly installments of Base Annual Rent. (c) Additional Rent Reconciliations. Within one hundred twenty (120) days -------------------------------- after the end of each calendar year, Landlord will submit to Tenant an financial statement of the actual increases in Real Estate Taxes and Operating Expenses paid during the Fiscal Year which ended during such calendar year over the Real Estate Taxes and Operating Expenses which were paid during the Base Year, respectively. Such statement shall also indicate the amount of Tenant's excess payment or underpayment of Additional Rent based on Landlord's estimate described in Sections 2.3(a) and 2.3(b). If Additional Rent paid by Tenant during the preceding calendar year shall be in excess of, or less than, the aggregate of its share of the actual increase in Real Estate Taxes and Operating Expenses, Landlord and Tenant agree to make the appropriate adjustment following the submission of Landlord's statement. Tenant shall either pay any Additional Rent due with the installment of Base Annual Rent due for the month following submission of Landlord's statement, or pay any Additional Rent due within thirty (30) days if the Lease Term has expired or has otherwise been terminated. Tenant shall deduct its excess payment, if any, from the installment of Base Annual Rent due for the month or months if necessary following submission of Landlord's statement, or following the expiration or earlier termination of the Lease Term, Tenant shall be reimbursed within thirty (30) days thereafter for any excess payments made, less any amounts then due Landlord under this Lease. (d) Verification of Additional Rent. Unless Tenant asserts specific errors -------------------------------- within six (6) months after Landlord has submitted the financial statement for a Fiscal Year to Tenant, Tenant shall have no right to contest the amount of Tenant's pro rata share of Real Estate Taxes and/or Operating Expenses or the statement submitted by Landlord. No such assertion of error by Tenant shall extend the time for payments as set forth in Sections 2.2 and 2.3 above. If Tenant <PAGE> has given a timely assertion of error and if it shall be determined by Landlord there is an error in Landlord's statement, Tenant shall be entitled to a credit for any overpayment, which shall be applied to any sums then due Landlord under this Lease and then to the next installment(s) of Additional Rent until fully credited for the overpayment, or refunded if Tenant has vacated the Demised Premises, or Tenant shall be billed for any underpayment and shall remit any amount owing to Landlord within ten (10) business days of Tenant's receipt of such statement. Tenant shall have the right to inspect Landlord's records of Operating Expenses and Real Estate Taxes for a given Fiscal Year or the Base Year, at Landlord's offices during normal business hours, on at least five (5) days prior written notice. Any overpayment by Tenant of Rent for such year reflected by such audit shall be promptly corrected. In the event as a result of such audit it shall be determined that Landlord overcharged Tenant more than five percent (5%) of the Operating Expenses or Real Estate Taxes, Landlord shall also reimburse Tenant all reasonable costs incurred by Tenant with respect to its audit. Tenant agrees that it shall not engage the services of an accountant or agent which is compensated on a contingency basis for purposes of conducting the audit. (e) Fiscal Year. Landlord shall have the right to change its Fiscal Year ------------ from time to time. If Landlord changes its Fiscal Year during the Lease Term, thereby creating a Fiscal Year with fewer than twelve (12) months (hereinafter "short year"), the Real Estate Taxes and Operating Expenses for the short year shall be determined on an annualized basis by taking the monthly average of the actual Real Estate Taxes and Operating Expenses, respectively, and multiplying each by twelve. The amounts determined by this method shall be used in determining the increases described in Sections 2.2(a) and 2.2(b) for the short year. 2.4 Rent Adjustment Limit. Notwithstanding any deductions from or ---------------------- adjustments to Base Annual Rent and Additional Rent as provided for above, in no event shall the total monthly installment of Base Annual Rent and Additional Rent to be paid by Tenant in any month during the Lease Term or any extension thereof be less than the monthly installment of Base Annual Rent stipulated in Section 1.3, except as required as the result of the Landlord's application of a credit due to Tenant pursuant to Section 2.3(c), or as otherwise expressly provided herein in the case of rent abatements to which the Tenant may be entitled arising out of, for example, fire or casualty damage. 2.5 Survival of Rent Obligation. The obligation of Tenant with respect to ---------------------------- payment of Base Annual Rent, as defined in Section 2.1, and Additional Rent as defined in Sections 2.2 and 2.10, together with all other sums due hereunder, accrued and unpaid during the Lease Term and the survival of Landlord's obligation to refund any overpayments of Base Annual Rent or Additional Rent and any other sums which may be overpaid hereunder, shall survive the expiration or earlier termination of this Lease. 2.6 Pro Rata Share. All space measurements shall be determined in --------------- accordance with GWCAR standard method of measurement. Tenant shall be entitled to verify the measurement of the Premises no later than the Rent Commencement Date, and in the event as a result of Tenant's measurement the Premises contain less than the number of square feet of leasable area set forth in the Lease (subject to Landlord's rights to independently verify such measurement), then and in such event both the Tenant's pro-rata share hereunder, as described in Section 1.5 of this Lease, and the amount of Base Annual Rent during the Lease Term and any extensions thereto shall be proportionately adjusted using the corrected measurement. 2.7 Prorated Rent. Any Base Annual Rent or Additional Rent payable -------------- pursuant to Sections 2.1 and 2.2 for one or more full calendar months in a partial Fiscal Year at the beginning or end of the Lease Term shall be prorated based upon the number of months in the Fiscal Year. Any Base Annual Rent or Additional Rent payable pursuant to Sections 2.1 and 2.2 for a portion of a calendar month shall be prorated based upon the number of days in the applicable calendar month. 2.8 Application of Rent. No payment by Tenant or receipt by Landlord of -------------------- lesser amounts of Base Annual Rent or Additional Rent than those required by this Lease shall be deemed to be other than on account of the earliest unpaid stipulated Base Annual Rent or Additional Rent. No endorsement or statement on any check or any letter accompanying any check or payment as Base Annual Rent or Additional Rent shall be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such Base Annual Rent and Additional Rent or pursue any other remedy provided in this Lease. Any credit due to Tenant hereunder by reason of overpayment of Base Annual Rent or Additional Rent shall first be applied to any Base Annual Rent, Additional Rent or other sums owed to Landlord by Tenant as set forth elsewhere in this Lease or if Tenant shall be in default when said credit shall be owed. <PAGE> 2.9 Late Payment Fee and Interest Charge. Except as expressly set forth in ------------------------------------- the next sentence, in the event any installment of Base Annual Rent or Additional Rent due hereunder is not paid within ten (10) calendar days after it is due, then Tenant shall also pay to Landlord as Additional Rent (a) a late payment fee equal to five percent (5%) of the payment as liquidated damages for the additional administrative costs incurred by Landlord as a result of such late payments, plus (b) an interest charge calculated at the rate of eighteen percent (18%) per annum on the delinquent payment from the date due until paid. In no event shall any late penalty or interest be payable by Tenant on any late payment of Base Annual Rent or Additional Rent to Landlord in the event Tenant remits to Landlord the late payment within five (5) days following written notice to Tenant that Landlord has failed to timely receive any payment to which Landlord is entitled under this Lease. However, in the event Tenant is late more than two (2) times in any twelve (12) month period, Landlord shall be entitled to the late charge and/or interest as provided in the Lease, without the necessity of such written notice, if such payment is not made by Tenant within five (5) days following the date when due. 2.10 Other Tenant Costs and Expenses. All costs and expenses which Tenant -------------------------------- assumes or agrees to pay to Landlord pursuant to this Lease, including without limitation costs of construction and alterations, shall be deemed Additional Rent, whether or not the same is specifically designated herein as Additional Rent, and, in the event of nonpayment thereof, Landlord shall have all the rights and remedies herein provided for the nonpayment of Base Annual Rent and Additional Rent payable pursuant to Sections 2.1 and 2.2, including assessment of late payment fees and interest charges. 3. CONSTRUCTION OF PREMISES AND OCCUPANCY 3.1 Tenant Plans, Construction and Rent Liability. Exhibit F, attached to ---------------------------------------------- this Lease, describes the obligations of Landlord and Tenant, and the respective time periods for performance thereof, for the preparation and approval of construction plans, cost estimates, working drawings and completion of improvements and fixturing for occupancy. The improvements to be constructed by Landlord in the Demised Premises are hereinafter referred to as the "Construction Improvements". Said time periods shall apply irrespective of whether Tenant uses the architect, engineer and/or general contractor selected by Landlord, or firms of Tenant's own selection. The Tenant shall deliver to Landlord, by the dates specified on Exhibit F, a preliminary plan approved in writing by the Tenant showing Tenant's partition, electrical and telephone requirements, planned occupancy numbers and distribution within the Demised Premises and all other requirements set forth in the Tenant Plans Guidelines, attached hereto and made a part hereof as Exhibit E, or otherwise deemed necessary by the Landlord for the preparation of the working drawings and cost estimate. (a) Preparation of Tenant Plans. ---------------------------- (i) Intentionally Deleted. (iii) Tenant's preliminary plan, whether prepared by an architect or engineer selected by Landlord or by Tenant's architect or engineer, shall provide sufficient information to permit Landlord to have working drawings and cost estimate prepared. Tenant's preliminary plan shall be certified by the architect or engineer preparing same to be in compliance with applicable building and fire codes, and with The Americans with Disabilities Act and all amendments, modifications, extensions, replacements, regulations, orders and directives in connection therewith (the "ADA"). If the Demised Premises as reflected on Tenant's plans are not in compliance with applicable building and fire codes, or do not comply with all requirements of the ADA, then Tenant's plans shall not be, nor shall they be deemed to be, acceptable to Landlord. Landlord's approval of Tenant's plans or work does not constitute certification by Landlord that said plans or work meet the applicable requirements of any building or fire codes, laws or regulations, or the ADA, nor shall it impose any liability whatsoever upon Landlord. If Tenant's preliminary plans are acceptable to Landlord, Landlord shall have working drawings prepared within the time period set forth on Exhibit F, and when the working drawings are completed by the architect and engineer, the Tenant shall approve in writing both the working drawings and Landlord's final cost estimate within the number of working days stipulated on Exhibit F. Tenant's failure to approve or disapprove any estimates or plans within the time periods set forth on Exhibit F shall be deemed to constitute approval for purposes of this Section. (b) Extension of Construction Timetable. Nothing contained in this Section ------------------------------------ 3.1, nor any delay in completing the Demised Premises, shall in any manner affect the Commencement Date set forth in Section 1.2 or Tenant's liability for payment of Base Annual Rent and Additional Rent from such Commencement Date, except as follows. If Landlord requires longer than the number of working days stipulated on Exhibit F, to prepare working drawings and prepare the cost estimate following receipt of Tenant's approved preliminary plan, or if Landlord requires longer than the number of working days stipulated on Exhibit F , to substantially complete Construction Improvements in the Demised Premises after the final working drawings and cost estimate have been approved by the Tenant in writing, then the Commencement Date shall be postponed by one day for each extra day Landlord requires for the foregoing preparation of working drawings and cost estimate and/or substantial completion of Construction Improvements, as the case may be, which postponement shall be Tenant's sole and exclusive remedy. In the event Tenant delays approval of either the preliminary plan, the working drawings and/or the final cost estimate or makes changes in the work after approval of working drawings and the final cost estimate, or Tenant's contractors interfere with Landlord's work, thereby delaying substantial completion and Landlord's tender of possession of the Demised Premises to Tenant, Tenant shall nevertheless remain liable for the payment of Base Annual Rent and Additional Rent from the Commencement Date specified in Section 1.2. Time is of the essence as to the Tenant's performance within the time periods specified for approval of plans and cost estimates set forth on Exhibit F pursuant to this Section 3.1. <PAGE> (c) Substantial Completion. For the purposes of this Section 3.1, ----------------------- "substantial completion" of the Construction Improvements shall mean when all work to be performed by Landlord pursuant to the approved working drawings and final cost estimate has been completed, except for minor items of work and minor adjustments of equipment and fixtures that can be completed after occupancy of the Demised Premises without causing material interference with Tenant's reasonable use of the Demised Premises (i.e., "punch-list" items) in accordance with the "use of the premises" as defined in Section 1.8. In the event Tenant's plans specify any Construction Improvements that are not building standard, or are not immediately available in the metropolitan Washington, D.C., area within the time period for construction set forth on Exhibit F, the delivery and installation of which precludes Landlord from substantially completing the Construction Improvements in the Demised Premises by the Commencement Date specified in Section 1.2, Tenant shall nevertheless remain liable for the payment of Base Annual Rent and Additional Rent from such Commencement Date. (d) Punchlist Items. Upon Tenant's request made not later than fifteen --------------- (15) days after the date Tenant commences business operations within the Premises, Landlord and Tenant shall jointly prepare and agree upon a punchlist of incomplete elements of Construction Improvements ("Punchlist"). Landlord shall commence work on the Punchlist within seven (7) days after the date of the Punchlist and shall continue and diligently attempt to complete all items on the Punchlist within thirty (30) days thereafter, but in any event not later than necessary to prevent material delay or interference with Tenant's use and occupancy of the Leased Premises. If Landlord and Tenant disagree whether an element of Construction Improvements should be included in the Punchlist or is properly completed, Landlord and Tenant shall submit the matter to review by an independent architect, and the decision of such architect shall bind both parties. Additionally, if there are any defects in material or workmanship in Construction Improvements which are not ascertainable from a careful physical inspection of the Premises by a qualified construction representative, Landlord shall correct such defects promptly. 3.2 Possession. If Landlord shall be unable to tender possession of the ----------- Demised Premises on the Commencement Date set forth in Section 1.2 by reason of: (a) the fact that the Demised Premises are located in a building being constructed and which has not been sufficiently completed to make the Demised Premises ready for occupancy; (b) the holding over or retention of possession of any tenant or occupant; (c) the Construction Improvements have not been substantially completed; or (d) for any other reason beyond the control of Landlord, Landlord shall not be subject to any liability for the failure to tender possession on said date. Under such circumstances the Base Annual Rent and Additional Rent reserved and covenanted to be paid herein shall not commence until possession of the Demised Premises is tendered to Tenant. No such failure to tender possession on the Commencement Date set forth in Section 1.2 shall in any other respect affect the validity of this Lease or the obligations of Tenant hereunder, nor shall same be construed to extend the termination date of this Lease set forth in Section 1.2. In the event the Commencement Date does not occur within six (6) months of the date this Lease is fully executed and delivered by Landlord and Tenant, then Landlord , without further liability, shall have the right to terminate this Lease upon thirty (30) days prior written notice to the Tenant. If permission is given to Tenant to enter into possession of the Demised Premises prior to the date specified as the Commencement Date, Tenant covenants and agrees that such occupancy shall be deemed to be subject to all of the terms, covenants, conditions and provisions of this Lease, and that Tenant shall be responsible for payment of Base Annual Rent, in advance, at the rate of 1/30th of the base monthly rent set forth in Section 1.3 for each day of such occupancy prior to the Commencement Date, and Additional Rent set forth in Section 1.5 shall begin to accrue on such date of possession. Notwithstanding any provision in this Lease to the contrary, Landlord and Tenant expressly recognize that a portion of the Premises is presently being occupied by GSA (the Federal Labor Relations Authority) as a hold-over tenant. Such portion is located on the fourth floor of the Building and contains approximately 5,000 square feet of rentable area. Landlord agrees to use all reasonable efforts to promptly tender such portion to Tenant, and in no event shall Landlord acquiesce to any extension of the holdover occupancy by GSA. Inasmuch as Tenant will not be afforded access to such portion concurrent with the remainder of the Premises to perform the Construction Improvements, the parties agree that notwithstanding the occurrence of the Commencement Date (as to the remainder of the Premises), no rent or other charges shall be payable by Tenant pertaining to such portion (pro-rated based upon a fraction 5,000/32,500) until such time as the Construction Improvements have been completed within such portion, and in the event delivery of such portion does not occur by December 15, 1998, to the extent that the costs of construction of the Construction Improvements is increased to Tenant by reason of the inability to perform the required work concurrent with the balance of the Premises, such increase in cost shall be borne solely by Landlord and not by Tenant. 3.3 Permits. Tenant shall be responsible for obtaining at its sole cost -------- and expense the construction and occupancy permits for the Demised Premises. Tenant shall be responsible for obtaining any other permits or licenses necessary for its lawful occupancy of the Demised Premises. Tenant shall provide Landlord with a copy of all such permits and licenses. 3.4 Intentionally Deleted. ---------------------- 4. SUBLETTING AND ASSIGNMENT 4.1 Consent. Without the prior written consent of Landlord, not to be -------- unreasonably withheld, conditioned or delayed in accordance with Section 4.5, Tenant will not sublet the Demised Premises or any part thereof or transfer possession or occupancy thereof to any person, firm or entity, or transfer or assign this Lease, and no subletting or assignment hereof shall be effected by operation of law or in any other manner, such as the transfer of all or substantially all of Tenant's assets or voting control of Tenant's stock, partnership interest or other equity, without such prior written consent of Landlord. All permitted sublettings and assignments of the Demised Premises and this Lease shall be subject to the provisions of this Lease, including but not limited to Section 4.3. No assignment shall be made except for the entire Demised Premises and Tenant further agrees that any permitted assignment of this Lease or subletting of the Demised Premises may be conditioned upon payment by Tenant of consideration and the <PAGE> delivery of such additional guarantees, collateral and/or other security as determined by Landlord. Any subletting or assignment consented to by Landlord, to be effective, shall be evidenced in writing in a form acceptable to Landlord. Consent by Landlord to any assignment or subletting by Tenant shall not operate as a waiver of the necessity for obtaining Landlord's consent in writing to any subsequent assignment or subletting. The collection or acceptance of rent from any such assignee, subtenant or other occupant shall not constitute a waiver of or release of Tenant from any covenant or obligation contained in this Lease, nor shall such acceptance of rent be deemed to create any right to the Demised Premises in such assignee, subtenant or other occupant, nor any legal or other relationship between the Landlord and any such assignee, subtenant or other occupant. Landlord's acceptance of any name for listing on the Building directory shall not be deemed, nor will it substitute for, Landlord's consent as required by this Lease, to each sublease, assignment and any other occupancy of the Demised Premises. In the event that Tenant defaults under this Lease in the payment of Base Annual Rent or Additional Rent following expiration of any applicable cure period, Tenant hereby assigns to Landlord the rent and other sums due from any subtenant, assignee or other occupant and hereby authorizes each such subtenant, assignee and other occupant to pay said rent and other sums directly to Landlord upon demand. Any transfer of this Lease or the Demised Premises, or any transfer of any interest in Tenant restricted pursuant to this Section 4.1, without the prior written consent of Landlord pursuant to this Section 4.1 shall be void. By taking a transfer of this Lease by assignment, transfer of interest in Tenant, or by any other manner described in this Section 4.1, or otherwise with Landlord's consent to the transfer, the transferee shall be bound by all provisions of this Lease, which shall be binding upon the transferee as if the transferee had signed this Lease in lieu of the original Tenant named herein. 4.2 Recapture of Premises. In the event Tenant desires to sublet the ---------------------- Demised Premises or assign this Lease or effect the transfer of any interest in this Lease or in Tenant restricted pursuant to Section 4.1, Tenant shall give to Landlord written notice of Tenant's intended subtenant, assignee or transferee in order to secure Landlord's written consent in accordance with Section 4.1. Within thirty (30) days of receipt of said notice, Landlord shall have the right, at its option to terminate this Lease by giving Tenant not less than thirty (30) days notice if Tenant's notice states the Tenant's desire to sublet more than fifty percent (50%) of the Demised Premises or effect a restricted transfer of an interest in this Lease. If Landlord exercises its right to terminate this Lease pursuant to the above provisions, Tenant agrees that Landlord shall have access to all or any portion of the Demised Premises as soon as Tenant has vacated the Premises.. Tenant and Landlord shall promptly execute such lease amendments and other documents as Landlord may require to effectuate the terms and intent of this Section 4.2. 4.3 Excess Rent and Other Consideration. Any rent and other consideration ------------------------------------ accruing to Tenant as a result of any sublease or any assignment of this Lease, which is in excess of the pro rata share of Base Annual Rent and Additional Rent then being paid by Tenant for all or a portion of the Demised Premises being sublet or assigned, shall be paid by Tenant to Landlord monthly as Additional Rent after recovery by Tenant of all of the costs and expenses incurred by Tenant with respect to the subletting or assignment. Any consideration accruing to Tenant as the result of any transfer of interest in this Lease restricted pursuant to Section 4.1, which is paid or deemed paid in regard to the value of this Lease (as opposed to any equipment or furnishings of Tenant located at the Building) and which is in excess of the pro rata share of the Base Annual Rent and Additional Rent which would have been paid by Tenant during the Lease Term for such space, shall be paid by Tenant to Landlord promptly as Additional Rent after recovery by Tenant of all of the costs and expenses incurred by Tenant with respect to the transfer of the interest in this Lease. 4.4 Tenant Liability. In the event of any subletting of the Demised ----------------- Premises or assignment of this Lease by Tenant or transfer of an interest in this Lease or in Tenant, Tenant shall remain liable to Landlord for payment of the Base Annual Rent and Additional Rent stipulated herein and all other covenants and conditions contained herein. No subletting of the Demised Premises or assignment of this Lease or transfer of an interest in this Lease or in Tenant shall operate to release, discharge or otherwise affect the liability of any guarantors, co-signers or other parties liable to Landlord pursuant to the terms of any guaranty or otherwise for the obligations of Tenant under this Lease. 4.5 Reasonable Standards of Consent. Tenant acknowledges that Landlord, in -------------------------------- considering whether to grant or withhold consent required of Landlord pursuant to this Section 4, shall be entitled to apply any or all of the following criteria: (a) The financial strength of proposed subtenant/assignee/ transferee must be acceptable to Landlord in Landlord's reasonable discretion based on adequate current and historical financial information given by Tenant. Landlord shall be entitled to receive, and Tenant shall deliver or cause others to deliver, such guarantees, collateral and other security as Landlord shall request in conjunction with any prospective sublease, assignment or other transfer. Failure to provide such financial information, guarantees, collateral and other security shall be grounds for Landlord to withhold or deny consent; (b) The proposed subtenant/assignee/transferee must have a good reputation in the business community and must be credit-worthy; (c) Use of the Demised Premises by the proposed subtenant/assignee/transferee must be identical to the use permitted by this Lease; (d) Use of the Demised Premises by the proposed subtenant/assignee/transferee shall not violate or create any potential violation of any laws and must be in keeping with the character of the Building and the Complex; (e) Use of the Demised Premises by the proposed subtenant/assignee/transferee shall not violate, or cause Landlord to violate, any other leases, agreements or mortgages affecting (i) the Demised Premises, the Building, the Complex or the land related to such improvements, or (ii) the Landlord, Landlord's Agent or other tenants, whether such leases, agreements or mortgages were entered into prior or subsequent to this Lease; <PAGE> (f) The proposed use shall compatible with all other uses within the Building or Complex and the proposed use or user shall not cause a diminution in the reputation of the Building, the Complex, Landlord, Landlord's Agent or other tenants; (g) In the event Tenant is in default, consent may be conditioned by Landlord that such default be cured. . 4.6 Other Transfers. Notwithstanding anything herein to the contrary, ---------------- Tenant shall not pledge, assign, transfer, encumber or otherwise convey its interest in the Demised Premises conditionally or as security for any obligations of Tenant to any third party, or otherwise. Any such transfer in violation of this provision shall be void. 4.7 Rights on Default. In the event Tenant defaults under this Lease after ------------------ notice and expiration of the applicable cure period, in addition to the rights and remedies of Landlord outlined in Section 12, Landlord, at its option, may elect to recognize any sublease between Tenant and any subtenant, or any agreement by which Tenant has granted any leasehold estate or interest in the Demised Premises, as a direct lease or agreement between Landlord and such subtenant or other grantee, upon written notice to Tenant and such subtenant or other grantee, without releasing or affecting the liability of Tenant to Landlord under this Lease, and Tenant shall be deemed to have assigned its interest in such sublease or other agreement to Landlord (without the need for executing any further documentation evidencing same) and such subtenant or other grantee shall attorn to and recognize the rights of Landlord under such sublease or other agreement, as the case may be. Notwithstanding Tenant's consent or acquiescence in the termination of this Lease and/or Tenant's voluntary surrender of the Demised Premises (or any portion thereof), Landlord may consider any sublease or other agreement transferring a leasehold estate or interest in the Demised Premises, and/or any right to use or possess the Demised Premises (or any portion thereof) by any subtenant or other grantee, terminated as of the date Landlord terminates this Lease and/or Tenant's right to possession of the Demised Premises, it being the intention of the parties that any leasehold estate or other interest in the Demised Premises shall be subject to the terms and conditions of this Lease, including all rights and remedies of Landlord outlined herein, notwithstanding anything to the contrary contained in such sublease or other agreement. 4.8 Notwithstanding the provisions set forth in section 4.1 hereinabove, in no event shall any sale or assignment of any of Tenant's stock be deemed to require Landlord's consent under this Lease. Further, Tenant shall have the right to transfer this Lease and/or sublet all or any part of the Leased Premises without obtaining Landlord's consent to any of the following: (1) any entity which at the time of such transfer is the record holder of all of the voting stock of Tenant; (2) any entity which at the time of such transfer is a wholly owned subsidiary of Tenant or an entity which is the then record holder of all of the voting stock of Tenant and into which Tenant has been consolidated; (3) any entity which shall result from a merger of the Tenant with one or more entities; or (4) any entity to whom Tenant or its shareholders shall have sold all or substantially all of Tenant's assets or the stock of Tenant. Tenant will agree to provide Landlord with copies of the Agreement executed by the assignee of this Lease evidencing the assumption by such assignee of all of the obligations and liabilities imposed upon Tenant under the Lease. Further, Tenant will acknowledge that it shall remain liable on the Lease, notwithstanding any such permitted transfer. If Landlord shall not respond to Tenant's request to assign or sublet within thirty (30) days of its presentment, such request shall be deemed approved by Landlord. 5. SERVICES AND UTILITIES 5.1 Building Standard Services and Utilities. Subject to the limitations ----------------------------------------- set forth in Section 5.3 below, Landlord shall furnish sufficient electric current for lighting and office equipment such as typewriters, calculators, small copiers, desktop personal computers and word processors and similar items. Landlord shall also furnish water for lavatory and drinking purposes, lavatory supplies, fluorescent tube replacements, automatically operated elevator service and nightly cleaning service in accordance with Landlord's prevailing practices (as set forth in Exhibit D attached hereto), as they may be modified from time to time, except that Landlord shall not be responsible for cleaning Tenant's kitchens, private bathrooms, rugs, carpeting (except vacuuming) and drapes. Char and cleaning service together with the other building services shall be conducted at a level commensurate with such services provided in other comparableoffice buildings in the downtown D.C. area. Landlord shall have no liability for and expressly disclaims any responsibility for the engineering, design, installation, provision of or maintenance of Tenant's telecommunications and data transmission systems and the inside wire associated therewith. Landlord further agrees to furnish heating and cooling during the appropriate seasons of the year, between the hours and on the days set forth in Section 1.7 (exclusive of legal public holidays as defined in section 6103(a) and (c) of Title 5 of the United States Code, as it may hereafter be amended, with holidays falling on Saturday observed on the preceding Friday and holidays falling on Sunday observed on the following Monday). All of the aforesaid services shall be provided without cost to Tenant except as such expenses may be included in calculating Additional Rent pursuant to the provisions of Sections 2.2 and 2.3. Landlord shall not be liable for failure to furnish, or for suspension or delay in furnishing, any of such services if such failure, suspension or delay is caused by breakdown, maintenance or repair work, strike, riot, civil commotion, governmental regulations, emergency periods due to weather or any other cause or reason whatever beyond the reasonable control of Landlord. Failure, suspension, delay or interruption of services shall not result in any abatement of Base Annual Rent or Additional Rent, be deemed an eviction or breach of this Lease (including any express or implied covenant of quiet enjoyment), or relieve Tenant of performance of Tenant's obligations under this Lease unless the Premises are rendered untenantable by such failure, suspension, <PAGE> delay or interruption of services due to the negligence or willful misconduct of Landlord, provided same continues for a period in excess of five (5) days following notice to Landlord of such failure, suspension, delay or interruption. In the event of any such failure, suspension, delay or interruption continuing as aforesaid, Tenant shall be entitled to abate paying all rents due hereunder with respect to the portion of the Premises (including also all of the Premises if applicable) which is affected by reason of the cessation of such service from the commencement of such loss of service until such service is restored. Landlord agrees to use its best efforts to restore any cessation in services, recognizing that Tenant's communication business requires twenty-four hour service, 365 days a year. 5.2 Overtime Services. Should Tenant require heating and cooling services ------------------ beyond the hours and/or days stipulated in Section 1.9, upon receipt of at least 48 hours prior written notice from Tenant, Landlord will furnish such additional service at the then-prevailing hourly rates (except as below provided) for both utility services and personnel as established by Landlord from time to time; provided, further, that there will be a minimum charge of four (4) hours each time overtime services are required on any Sundays or federal holidays, and a minimum charge of one and one-half (1.5) hours each time overtime services are required on any other day so long as such services are requested to be provided during a time period occurring immediately after the Building standard hours for such day (i.e. after 6:00 p.m. on weekdays or noon on Saturdays). Notwithstanding the foregoing, Landlord agrees that to the extent Tenant designates particular portions of the Premises as 24 hour zones, Landlord shall provide at its direct cost (i.e. no profit, administrative charge, overhead or markup) utilities necessary to permit Tenant to operate on a 24 hours a day, seven days a week basis, either the building standard system servicing such zone (if feasible) or Tenant's supplemental unit servicing such zone. Tenant shall be entitled from time to time during the term to revise those portions of the Premises designated as 24 hour zones. Landlord shall cooperate with Tenant in the provision of chiller water, and other utilities recognizing that Tenant's business operations require the conduct of business round-the-clock within certain areas. 5.3 Excessive Usage. ---------------- (a) Equipment Restrictions. Tenant will not install or operate in the ----------------------- Demised Premises any heavy duty electrical equipment or machinery or any other equipment which consumes excess gas (where applicable), excess water, excess sewer services or excess electricity as defined in Section 5.3(b) below, without first obtaining prior written consent of Landlord which approval shall not be unreasonably withheld, delayed or conditioned. Landlord may, among other things, require as a condition to its consent for the installation of such equipment or machinery that Tenant pay as Additional Rent the costs for excess consumption of such utilities that may be occasioned by the operation of said equipment or machinery. Landlord may make periodic inspections of the Demised Premises at reasonable times and upon reasonable advance notice to determine that Tenant's equipment and machinery comply with the provisions of this Section and Section 5.4. (b) Excess Electrical Usage. The consumption of electricity, including ------------------------ lighting, in excess of five (5) watts per square foot for any portion of the Demised Premises shall be deemed excessive. Additionally, any individual piece of electrically operated machinery or equipment having a name plate rating in excess of two (2) kilowatts shall also be deemed as requiring excess electric current. (c) Additional Utility Costs. Landlord shall have the right to either ------------------------- require that one or more separate meters be installed to record the consumption or use of electricity or other utilities, or cause a reputable independent engineer to survey and determine the quantity of such utilities consumed by such excessive use. In the event that excess consumption is determined, the cost of any such survey and meters and of installation, maintenance and repair thereof shall be paid for by Tenant. Tenant agrees to pay Landlord (or the utility company, if direct service is provided by the utility company), promptly upon demand therefor, for all such consumption and demand as shown by said meters, or a flat monthly charge determined by the survey, as applicable, at the rates charged for such service by the local public utility company.

All public liability insurance and property damage insurance shall insure Landlord and Landlord's Agent with coverage no less in scope than that necessary to meet Tenant's obligations outlined in Sections 8.1, 8.2 and 8.3 and elsewhere in this Lease. The policy shall contain an assumed contractual liability endorsement that refers expressly to this Lease. (b) Fire and Casualty Insurance. During the Lease Term, Tenant at its cost ---------------------------- shall maintain fire and extended coverage insurance on all special or above building standard work (as defined in Exhibit B, if applicable), all alterations and all other contents of the Demised Premises, including any Leasehold Improvements and Tenant's Property, in an amount sufficient so that no coinsurance penalty will be applied in case of loss. (c) Increases in Coverage. Tenant shall increase its insurance coverage as ---------------------- required if in the reasonable opinion of the mortgagee on the Building, Landlord or Landlord's insurance agent such insurance coverage at that time is not adequate. (d) Policy Requirements. All insurance required under this Lease shall be ------------------- issued by insurance companies authorized to do business in the jurisdiction where the Building is located. Such companies shall have a policyholder rating of at least "A" and assigned a financial size category of at least "Class X" as rated in the most recent edition of "Best's Key Rating Guide" for insurance companies. If at any time during the Lease Term the rating of any of Tenant's insurance carriers is reduced below the rating required pursuant to the terms hereof, Tenant shall promptly replace the insurance coverage(s) maintained with such carrier with coverage(s) from a carrier whose rating complies with the foregoing requirements. If the Best's Key Rating Guide is discontinued or revised without substitution of a comparable rating system, Landlord shall reasonably determine its satisfaction with the insurance company issuing Tenant's policies. Each policy shall contain an endorsement requiring thirty (30) days written notice from the insurance company to Landlord before cancellation or any change decreasing coverage, scope or amount of such policy and an endorsement naming Landlord and Landlord's Agent as additional insureds. Each policy, or a certified copy of the policy, and a certificate showing it is in effect, together with evidence of payment of premiums, shall be deposited with Landlord at the commencement of the Lease Term and thereafter upon any policy changes or substitutions, and renewal certificates and copies of renewal policies shall be delivered to Landlord at least thirty (30) days prior to the expiration date of any policy. <PAGE> (e) No Limitation of Liability. Notwithstanding the fact that any --------------------------- liability of Tenant to Landlord may be covered by Tenant's insurance, Tenant's liability shall in no way be limited by the amount of its insurance recovery or the amount of insurance in force or required by any provisions of this Lease. (f) Waiver of Subrogation. Notwithstanding anything to the contrary ---------------------- contained herein, Landlord and Tenant hereby mutually waive and release their respective rights of recovery against each other for any loss of its property (in excess of a reasonable deductible amount) capable of being insured against by fire and extended coverage insurance or any insurance policy providing property damage coverage, whether carried or not. Each party shall apply to its insurer to obtain said waiver and obtain any special endorsement, if required by its insurer to evidence compliance with the aforementioned waiver, and shall bear the cost therefor. (g) Business Interruption. Landlord, Landlord's Agent and their ---------------------- respective agents and employees shall have no liability or responsibility for any loss, cost, damage or expense arising out of or due to any interruption of business regardless of the cause therefor), increased or additional cost of operation of their business or other costs or expenses, whether similar or dissimilar, which are capable of being insured against under business interruption insurance, whether or not carried by Tenant. 8.6 Incident Reports. Tenant shall promptly report to Landlord's Agent all ----------------- accidents and incidents actually known by officers of Tenant occurring on or about the Demised Premises which involve or relate to the security and safety of persons and/or property. Tenant also agrees that it shall use reasonable efforts to notify Landlord of any other similar incidents actually known by Tenant's President affecting portions of the Building beyond the Demised Premises, but Tenant shall have no liability or responsibility to either Landlord or any third party by reason of Tenant's failure to notify Landlord of any such incident. 9. DAMAGE 9.1 Damages Caused by Tenant. Subject to the provisions of Sections 8.5(f) ------------------------- and 9.2, in the event of damage to the Demised Premises or other portions of the Building caused by the acts or omissions of Tenant, its agents or employees, Landlord may, but shall not be obligated to, repair such damage at the expense of Tenant, or, at Landlord's option, such damages shall be repaired by Tenant, at Tenant's expense, with Landlord's approval in accordance with Section 6.4. At Landlord's option, Tenant shall either (a) pay to Landlord the estimated cost of such repairs and/or maintenance within ten (10) days of Tenant's receipt of Landlord's estimate, or (b) upon completion of such repairs and/or maintenance by Landlord, pay to Landlord the actual cost of such repairs and/or maintenance (or the difference between the actual cost and the estimated costs previously paid by Tenant) within ten (10) days of receipt of invoice from Landlord. Landlord's recovery shall not be limited to the diminution in the value of the Demised Premises or leasehold notwithstanding that such repairs and maintenance may occur prior to the expiration of the Lease Term. All such costs shall be deemed Additional Rent. This provision shall be construed as an additional remedy granted to Landlord and not in limitation of any other rights and remedies which Landlord has or may have in said circumstances. 9.2 Fire or Casualty Damage. In the event of damage or destruction of ------------------------ the Demised Premises or a portion thereof by fire or any other casualty not due to the acts or omissions of Tenant, its agents, employees, invitees or visitors, then, except as otherwise provided in Section 9.3, this Lease shall not be terminated, but structural damage to the Demised Premises, including demising partitions and doors, shall be promptly and fully repaired and restored as the case may be by Landlord at its own cost and expense. Due allowance, however, shall be given for reasonable time required for adjustment and settlement of insurance claims, for such other delays as may result from government restrictions and controls on construction, if any, and for strikes, national emergencies and other conditions beyond the control of Landlord. Restoration by Landlord shall not include replacement of Tenant's Property but shall include restoration of the Demised Premises including also all Construction Improvements. Tenant shall, at its expense, repair, restore and replace Tenant Property and all elements of the Demised Premises excluded from the scope of Landlord's duty to restore pursuant to this Section 9.2. Tenant's restoration, replacement and repair work shall comply with Section 6 hereof and Tenant shall maintain adequate insurance on all such replacements, restoration and property pursuant to Section 8.5 hereof. In the event of fire or casualty damage to the Demised Premises caused by the fault, act or omission or neglect of Tenant, its agents, employees, invitees or visitors, Landlord may, but shall not be obligated to, restore all or any portion of the damage described herein (which may or may not include the Demised Premises). It is agreed that in any of the aforesaid events, this Lease shall continue in full force and effect. 9.3 Untenantability. ---------------- (a) Restoration Requirements. ------------------------- (i) If the condition referred to in Section 9.2 is such that the Demised Premises are partially damaged or destroyed and provided that the condition was not due to the acts or omissions of Tenant, its agents, employees, invitees or visitors, then during the period that Tenant is deprived of the use of the damaged portion of the Demised Premises, Tenant shall be required to pay Base Annual Rent and Additional Rent covering only that part of the Demised Premises that Tenant is able to occupy, based on the ratio between the square foot area remaining that can be occupied for the conduct of business in Tenants' reasonable discretion and the total square foot area of the entire Demised Premises covered by this Lease. Any unpaid or prepaid installment of Base Annual Rent and Additional Rent for the month in which the condition referred to in Section 9.2 occurs shall be prorated. <PAGE> (ii) (1) If the condition referred to in Section 9.2 is such so as to make the entire Demised Premises untenantable and provided that the condition was not due to the acts or omissions of Tenant, its agents, employees, invitees or visitors, then, subject to the rights set forth in Section 9.3(a)(ii)(2) below, the installment(s) of Base Annual Rent and Additional Rent which Tenant is obligated to pay hereunder shall abate as of the date of the occurrence until the first to occur of either (x) expiration of thirty days following the date that the restoration of the Demised Premises has been substantially completed by Landlord to the extent of Landlord's obligations as described in Section 9.1 or (y) commencement by Tenant of beneficial use and occupancy for conduct of business within the damaged portion. Any unpaid or prepaid installment of Base Annual Rent and Additional Rent for the month in which the condition referred to in Section 9.2 occurs shall be prorated. (2) In the event (x) the Demised Premises are substantially or totally destroyed by fire or other casualty so as to be entirely untenantable, (y) a substantial portion of the Building is destroyed or damaged to such an extent that, in the sole judgment of Landlord, the Building cannot be operated as a functional unit or an economically viable unit, or (z) the damage to the Demised Premises and/or the Building is due to an uninsured risk or insurance proceeds are otherwise unavailable to cover the expenses of restoration or repair of the damage (less any applicable deductible), then Landlord or Tenant shall have the unconditional right to cancel this Lease in its sole discretion, in which case Base Annual Rent and Additional Rent shall be apportioned and paid to the date of said fire or other casualty. If Landlord elects not to cancel this Lease, then Landlord shall determine and notify Tenant in writing, within sixty (60) days following the fire or other casualty, provided that Landlord shall also cancel the Leases of all similarly situated tenants in the Building, of the date by which the Demised Premises can be restored by Landlord in accordance with the provisions of Section 9.1. If the date determined by Landlord as aforesaid for completion of restoration of the Demised Premises is more than one hundred twenty (120) days after such fire or other casualty, then Tenant shall have the right, to be exercised by giving written notice to Landlord within ten (10) days following receipt of such notice from Landlord, to cancel and terminate this Lease. In the event the date by which Landlord determines it can complete restoration of the Demised Premises as herein provided is less than 120 days following such fire or other casualty, or Tenant fails to terminate this Lease as herein provided following notification from Landlord that completion of restoration will require more than 120 days, then this Lease shall remain in full force and effect and Landlord shall commence restoration of the Demised Premises to the extent of Landlord's obligations as described in Section 9.2. Due allowance, however, shall be given for reasonable time required for adjustment and settlement of insurance claims, for Landlord to reasonably be able to determine the time necessary for completion of the restoration and for other such delays as may result from government restrictions and controls on construction, if any, and for strikes, national emergencies and other conditions beyond the control of Landlord. Any delays as a result of the foregoing shall operate to postpone Landlord's obligation to complete restoration of the Demised Premises by one day for each day of any such delay. Tenant shall commence any restoration to be performed by Tenant as required in Section 9.2 and Tenant shall reoccupy the Demised Premises when restored. (iii) Except as expressly provided in this Section 9.3, no compensation, or claim, or diminution of Base Annual Rent or Additional Rent will be allowed or paid by Landlord, by reason of inconvenience, annoyance, or injury to business, arising from any fire or other casualty suffered by Tenant or the necessity of repairing or restoring the Demised Premises or any portion of the Building. (b) Casualty Near Expiration of Lease Term. In addition to any other right --------------------------------------- of Landlord or Tenant to terminate this Lease pursuant to the provisions of this Section 9, in the event the Demised Premises are damaged in whole or in part by fire or other casualty during the last twelve (12) months of the Lease Term, then Landlord or Tenant, upon ten (10) days prior written notice to the other given within sixty (60) days of the date of the fire or casualty, may terminate this Lease, in which case the Base Annual Rent and Additional Rent shall be apportioned and paid to the date of said fire or other casualty. 10. CONDEMNATION 10.1 Landlord's Right to Award. Tenant agrees that if any of the Demised -------------------------- Premises or the Building shall be taken or condemned for public or quasi-public use or purpose by any competent authority, Tenant shall have no claim against Landlord and shall not have any claim or right to any portion of the amount that may be awarded as damages or paid as a result of any such condemnation. All rights of Tenant to damages therefor, if any, are hereby assigned by Tenant to Landlord. Upon such condemnation or taking, the Lease Term shall cease and terminate from the date of such governmental taking or condemnation. If (a) the whole or a substantial part of the Demised Premises of the Building is taken or condemned or if (b) less than a substantial portion of the Building or the Demised Premises is taken or condemned and the remainder of either in Landlord's opinion can not be operated as a functional unit or as an economically viable unit, Landlord shall notify Tenant of the termination of this Lease effective as of the date of such governmental taking or condemnation. In the event of any termination of this Lease by reason of any taking or condemnation, Tenant shall have no claim against Landlord or Landlord's Agent for the value of any unexpired portion of the Lease Term. If less than a substantial part of the Demised Premises or of the Building is taken or condemned by any governmental authority for public or quasi-public use or purpose and the remainder of both, in Landlord's opinion, can be operated as a functional unit or as an economically viable unit, the rent shall be equitably adjusted on the date when title vests in such governmental authority and the Lease shall otherwise continue in full force and effect. For the purposes of this Section 10, a substantial part of the Demised Premises shall be considered to have been taken if more than fifty percent (50%) of the Demised Premises are unusable by Tenant. 10.2 Tenant's Right to File Claim. Nothing in Section 10.1 shall preclude ----------------------------- Tenant from filing a separate claim against the condemning authority for the value of its Leasehold Improvements not then depreciated (excluding those <PAGE> Leasehold Improvements paid for by Landlord) and relocation expenses, provided that any award to Tenant will not result in a diminution of any award to Landlord. 11. BANKRUPTCY 11.1 Events of Bankruptcy. The following shall be Events of Bankruptcy --------------------- under this Lease: (a) Tenant's becoming insolvent, as that term is defined in Title 11 of the United States Code, entitled Bankruptcy, 11 U.S.C. Sec. 101 et seq. (the "Bankruptcy Code"), or under the insolvency laws of any State, District, Commonwealth or Territory of the United States ("Insolvency Laws"); (b) The appointment of a receiver or custodian for any or all of Tenant's Property or assets, or the institution of a foreclosure action upon any of Tenant's real or personal property; (c) The filing of a voluntary petition under the provisions of the Bankruptcy Code or Insolvency Laws; (d) The filing of an involuntary petition against Tenant as the subject debtor under the Bankruptcy Code or Insolvency Laws, which is either not dismissed within sixty (60) days of filing, or results in the issuance of an order for relief against the debtor, whichever is earlier; or (e) Tenant's making or consenting to an assignment for the benefit of creditors or a common law composition of creditors. 11.2 Landlord's Remedies. -------------------- (a) Termination of Lease. Upon occurrence of an Event of Bankruptcy, --------------------- Landlord shall have the right to terminate this Lease by giving written notice to Tenant; provided, however, that this right to terminate shall have no effect while a case in which Tenant is the subject debtor under the Bankruptcy Code is pending, unless Tenant or its Trustee is unable to comply with the provisions of Sections 11.2(d) and (e) below. At all other times this Lease shall automatically cease and terminate, and Tenant shall be immediately obligated to quit the Demised Premises upon the giving of notice pursuant to this Section 11.2(a). Any other notice to quit, or notice of Landlord's intention to re- enter is hereby expressly waived. If Landlord elects to terminate this Lease, everything contained in this Lease on the part of Landlord to be done and performed shall cease without prejudice, subject, however, to the rights of Landlord to recover from Tenant all Base Annual Rent and Additional Rent and any other sums accrued up to the time of termination or recovery of possession by Landlord, whichever is later, and any other monetary damages sustained by Landlord. (b) Suit for Possession. Upon termination of this Lease pursuant to -------------------- Section 11.2(a), Landlord may proceed to recover possession of the Demised Premises under and by virtue of the provisions of the laws of any applicable jurisdiction, or by such other proceedings, including reentry and possession, as may be applicable, or by direct order from any Court having jurisdiction over Tenant/Debtor, including any Bankruptcy Court. (c) Non-Exclusive Remedies. Without regard to any action by Landlord as ----------------------- authorized by Sections 11.2(a) and (b) above, Landlord may at its discretion exercise all the additional provisions set forth below in Section 12. (d) Assumption or Assignment by Trustee. In the event Tenant becomes the ------------------------------------ subject debtor in a case pending under the Bankruptcy Code, Landlord's right to terminate this Lease pursuant to Section 11.2(a) shall be subject to the rights of the Trustee in Bankruptcy to assume or assign this Lease. In addition to all other objections Landlord may raise to assumption and/or assignment, and in addition to all other requirements of any Bankruptcy Court and the Bankruptcy Code, the Trustee shall not have the right to assume or assign this Lease unless the Trustee (i) has timely performed all Lease obligations of the Tenant/Debtor arising from and after the filing of any voluntary bankruptcy petition by Tenant or, in the case of an involuntary petition, the date of entry of the Order for Relief, (ii) promptly cures all defaults under this Lease, (iii) promptly compensates Landlord for monetary damages incurred as a result of such default, and (iv) provides adequate assurance of future performance on the part of Tenant or on the part of the assignee of Tenant or the Trustee. (e) Adequate Assurance of Future Performance. Landlord and Tenant hereby ----------------------------------------- agree in advance that adequate assurance of future performance, as that term is used in Section 11.2(d) above, shall mean that all of the following minimum criteria must be met: (i) Tenant's gross revenues in the ordinary course of business during the thirty (30) day period immediately preceding the initiation of the case under the Bankruptcy Code must be at least two (2) times greater than the next installment of Base Annual Rent and Additional Rent due under this Lease; (ii) both the average and median of Tenant's gross revenues in the ordinary course of business during the six (6) month period immediately preceding the initiation of the case under the Bankruptcy Code must be at least two (2) times greater than the next six (6) installments of Base Annual Rent and Additional Rent due under this Lease; (iii) Tenant must pay (and continue to pay on a timely basis throughout the Lease Term) Base Annual Rent, Additional Rent and all other sums payable by Tenant hereunder in advance and as a condition precedent to the performance of Landlord's obligations hereunder; (iv) the Trustee must agree that Tenant's business shall be conducted in a first class manner, and that no liquidating sales, auctions, or other non-first class business operations shall be conducted on or about the Demised Premises, Building and/or Complex; (v) the Trustee must agree that the use of the Demised Premises as stated in this Lease will remain unchanged and that no prohibited use shall be permitted; and <PAGE> (vi) the Trustee must agree that the assumption or assignment of this Lease will not violate or affect the rights of other tenants in the Building and/or Complex. (f) Failure to Provide Adequate Assurance. In the event the Trustee or -------------------------------------- Tenant is unable to (i) comply with the requirements of Section 11.2(d) above, or (ii) meet the criteria and obligations imposed by Section 11.2(e) above, Tenant agrees in advance that it has not met its burden to provide adequate assurance of future performance, and this Lease may be terminated by Landlord in accordance with Section 11.2(a) above. 11.3 Guarantors. For purposes of this Section 11, any action or ----------- adjudication by or on behalf of, or against, or with respect to the property or affairs of, any guarantor or guarantors (if any) of this Lease, or any of them, which, if taken by, against or with respect to Tenant, Tenant's Property or affairs, would entitle Landlord to exercise any remedy specified herein, may be treated, at Landlord's sole option and discretion, as though it were taken by, against or with respect to the Tenant. 11.4 Damages. In the event of cancellation and termination of this Lease -------- pursuant to Section 11.2 above, Landlord shall, notwithstanding any other provisions of this Lease to the contrary, be entitled to promptly recover damages from Tenant determined in accordance with the provisions set forth in Section 12.2 of this Lease as provided for in the case of default by Tenant. 12. DEFAULTS AND REMEDIES 12.1 Default. Subject to the provisions of Section 12.1(i) below, if any -------- one or more of the following events occur, said event shall be deemed a material default of this Lease: (a) Tenant's failure to complete, within the time periods required by this Lease, any tasks required for the preparation or approval of plans for the construction and/or completion of the Demised Premises prior to the Commencement Date; (b) Tenant's failure to accept possession of the Demised Premises when tendered by Landlord; (c) Tenant's failure to pay any installment of Base Annual Rent, Additional Rent or other sum required to be paid by Tenant when the same shall be due and payable, all without demand unless demand is necessary under the express terms of this Lease (in which case a material default shall be deemed to occur if such payment is not made strictly within the time period provided for such payment following the demand); (d) Tenant's failure to perform or observe any other term, covenant or condition of this Lease; (e) Any event expressly designated or deemed a default elsewhere in this Lease; (f) Any execution, levy, attachment or other legal process of law shall occur upon Tenant's Property, Tenant's interest in this Lease or the Demised Premises; (g) Tenant's abandonment or surrender of the Demised Premises prior to the expiration of the Lease Term and the suspension of rent payments as the same may become due and payable; and/or (h) Tenant's committing or permitting waste to occur to the Demised Premises. (i) Notwithstanding any provision contained in the Lease to the contrary, in no event shall Tenant be deemed to be in default under the Lease, nor shall a material default be deemed to have occurred in the absence of either (A) Tenant's failure to cure a monetary default following the giving of written notice to Tenant and the expiration of ten (10) days thereafter, or (B) in the case of a non-monetary default, Tenant's failure to cure following the giving of written notice to Tenant and the expiration of thirty (30) days thereafter, provided, however that the aforesaid thirty (30) days period shall be deemed extended to include such additional time as may reasonably be required to cure same, provided Tenant has commenced in good faith its cure within such thirty (30) day period and Tenant diligently prosecutes its cure to completion. 12.2 Remedies. In each and every such event set forth in Section 12.1 --------- above, from the date of such default and at all times thereafter, at the option of Landlord, Tenant's right of possession shall thereupon cease and terminate. Landlord shall be entitled to all rights and remedies now or later allowed at law or in equity, all of which shall be cumulative to the extent that the exercise of any one or more rights or remedies shall not be deemed to constitute a waiver of the Landlord's right to exercise any one or more other rights and remedies herein provided or provided at law or in equity. Landlord shall be entitled to obtain possession of the Demised Premises whether or not Landlord elects to terminate this Lease, and to re-enter the same without demand of rent or demand of possession of the Demised Premises and may forthwith proceed to recover possession of the Demised Premises by any lawful means or process of law whether or not Landlord elects to terminate this Lease, any notice to quit being hereby expressly waived by Tenant. In the event of such re-entry by process of law or otherwise, Tenant nevertheless agrees to remain liable for all Base Annual Rent, Additional Rent and other sums due under this Lease, and shall pay the same as and when it accrues and is payable hereunder. Landlord may (but shall not be obligated to) declare the entire balance (or any portion thereof) of Base Annual Rent, Additional Rent and all other sums payable by Tenant hereunder for the remainder of the Lease Term to be immediately due and payable in full, which shall be <PAGE> recoverable and determined pursuant to Section 12.4 below. Tenant further agrees to remain liable for any and all damage, deficiency, and loss of Base Annual Rent, Additional Rent and other sums herein specified, and all other damages which Landlord may sustain by such re-entry, including reasonable attorneys' fees and costs. If under the provisions hereof, a seven (7) days summons or other applicable summary process shall be served, and a compromise or settlement thereof shall be made, such action shall not constitute a waiver of any breach of any covenant, term, condition or agreement herein contained. 12.3 Landlord's Right to Relet. Should this Lease be terminated before the -------------------------- expiration of the Lease Term, by reason of Tenant's default as provided in Sections 11 or 12, or if Tenant shall abandon the Demised Premises before the expiration or termination of the Lease Term and without paying the rent due as the same may become due and payable (whether or not Landlord elects to terminate this Lease), the Demised Premises may be relet by Landlord, on Tenant's behalf or for the account of Landlord, as Landlord so chooses, for such rent and upon such terms as are reasonable under the circumstances. If the full rent reserved under this Lease (and any of the costs, expenses or damages indicated below) shall not be realized by Landlord, Tenant shall be liable for all damages sustained by Landlord, including, without limitation, deficiency in Base Annual Rent, Additional Rent, reasonable attorneys' fees, other collection costs, brokerage fees attributable to the unexpired portion of the Term hereof, expenses incurred by Landlord to remove Tenant's Property and (at Landlord's option) Leasehold Improvements, and expenses of placing the Demised Premises in first-class rentable condition. Landlord, in putting the Demised Premises in good order or preparing the same for reletting may, at Landlord's option, make such alterations, repairs or replacements in or relating to the Demised Premises as Landlord, in Landlord's sole judgment, considers advisable and necessary for the purpose of reletting the Demised Premises, and the making of such alterations, repairs or replacements shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall use commercially reasonable efforts to mitigate its damages nor shall Landlord be liable in any way whatsoever for failure to relet the Demised Premises, or in the event that the Demised Premises are relet, for failure to collect the rent thereof under such reletting. For the purpose of calculating Landlord's damages as set forth in Section 12.4 below, if the Building has other available space at the time of such Lease termination or Tenant's abandonment or vacating of the Demised Premises, or anytime thereafter, the Demised Premises shall be deemed the last space rented int he Building even though the Demised Premises may be re-rented by Landlord prior to such other vacant space. In no event shall Tenant be entitled to receive any excess, if any, of rent (if any) collected over the sums payable by Tenant to Landlord hereunder. 12.4 Recovery of Damages. -------------------- (a) Quantification of Damages. Any damage, deficiency, loss of Base Annual -------------------------- Rent, Additional Rent or other sums payable by Tenant hereunder, unamortized Landlord Concessions as described hereinafter, and all other damages may be recovered by Landlord, at Landlord's option, upon default by Tenant, in separate actions, from time to time, as said damage shall have periodically accrued, or, at Landlord's option, may be deferred until the expiration of the Lease Term (in which event Tenant hereby agrees that the cause of action shall not be deemed to have accrued until the date of expiration of said Lease Term), or, at Landlord's option, in a single action in the event Landlord shall have declared the entire balance of Base Annual Rent, Additional Rent and other sums due under this Lease immediately due and payable pursuant to Section 12.2. In the event Landlord shall have declared the entire balance of Base Annual Rent, Additional Rent and other sums due under this Lease immediately due and payable, then in lieu of the Base Annual Rent and Additional Rent which would have been payable for the period after the date of any judgment obtained in any action by Landlord against Tenant to recover damages, Tenant shall pay a sum representing liquidated damages, and not penalty, in an amount equal to the excess of (i) the sum of the Base Annual Rent and Additional Rent provided for in this Lease for the unexpired portion of the Lease Term after the date of judgment discounted at a rate of three percent (3%) per annum to present value, over (ii) the rental value of the Leased Premises, at the time of termination of this Lease, for the unexpired portion of the Lease Term, discounted at a rate of three percent (3%) per annum to present value. In determining the rental value of the Leased Premises, the rent realized by any reletting accomplished or accepted by Landlord within a reasonable time after termination of this Lease, shall be deemed, prima facie, to be the rental value. (b) Non-Exclusive Rights. The provisions contained in this Section 12.4 --------------------- shall be in addition to and shall not prevent the enforcement of any claim Landlord may have against Tenant for anticipatory breach of the unexpired Lease Term. All rights and remedies of Landlord under this Lease shall be cumulative and shall not be exclusive of any other rights and remedies provided to Landlord under applicable law. In the event Tenant becomes the subject debtor in a case under the Bankruptcy Code, the provisions of this Section 12.4 may be limited by the limitations of damage provisions of the Bankruptcy Code. 12.5 Waiver. If under the provisions hereof Landlord shall institute ------- proceedings and a compromise or settlement thereof shall be made, the same shall not constitute a waiver of any agreement, covenant, condition, rule or regulation herein contained nor of any of Landlord's rights hereunder. No waiver by Landlord or Tenant of any breach of any agreement, covenant, condition, rule or regulation herein contained, on one or more occasions, shall operate as a waiver of such agreement, covenant, condition, rule or regulation itself, or of any subsequent breach thereof. No provision of this Lease shall be deemed to have been waived by Landlord or Tenant unless such waiver shall be in writing signed by Landlord or Tenant, as the case may be. Receipt and acceptance by Landlord of any Base Annual Rent, Additional Rent or other charges, or the performance of any obligation by Tenant hereunder, with knowledge of the breach of any agreement, covenant, condition, rule or regulation of this Lease by Tenant shall not be deemed a waiver of such breach. Failure of Landlord to enforce any of the rules and regulations against Tenant or any other tenant in the Building shall not be deemed a waiver of any such rule or regulation. No payment by Tenant or receipt by Landlord of a lesser amount than the Base Annual Rent and Additional Rent herein stipulated shall be binding upon Landlord or Tenant, nor shall the same be deemed to be other than on account of the stipulated Base Annual Rent and Additional Rent. No endorsement or statement on any check, letter or other transmittal accompanying any check or payment of Base Annual Rent, Additional Rent or other sum due from <PAGE> Tenant shall be deemed a settlement of a legal dispute or an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such Base Annual Rent, Additional Rent and other sums or to pursue any other remedy provided in this Lease. Landlord's consent to, or approval of, any act by Tenant requiring Landlord's consent or approval shall not be deemed to waive or render unnecessary Landlord's consent to or approval of any subsequent act by Tenant. 12.6 Anticipatory Repudiation. ------------------------- (a) Repudiation Prior to Commencement Date. If, prior to the Commencement --------------------------------------- Date or the first day of any extension or renewal period set forth in an extension or renewal option validly exercised by Tenant hereunder, Tenant notifies Landlord of or otherwise unequivocally demonstrates an intention to repudiate this Lease or breach any obligation of Tenant hereunder, Landlord may, at its option, consider such anticipatory repudiation a breach and material default of this Lease. In addition to any other remedies available to it hereunder or at law or in equity, Landlord may retain all Base Annual Rent, Additional Rent and other sums paid by Tenant hereunder, including any security deposit, if any, to be applied to damages of Landlord incurred as a result of such repudiation, including, without limitation, all damages and remedies reserved to Landlord in this Section 12 or elsewhere in this Lease, as applicable. It is agreed between the parties that for the purpose of calculating Landlord's damages, if the Building has other available space at the time of or subsequent to Tenant's breach, the Demised Premises covered by this Lease shall be deemed the last space rented in the Building even though the Demised Premises may be re-rented prior to such other vacant space. In the event a default occurs prior to the Commencement Date, Tenant shall, in addition to all other damages to which Landlord is entitled under this Lease, pay in full for all Leasehold Improvements constructed or installed within the Demised Premises through the date of the default, and for material ordered at Tenant's request for the Demised Premises (whether at Tenant's request or upon Landlord's anticipation of Tenant's needs hereunder) or for such material restocking charges. (b) Repudiation of Any Obligation of Tenant During Lease Term. If during ---------------------------------------------------------- the Lease Term Tenant notifies Landlord of or otherwise unequivocally demonstrates an intention to repudiate this Lease or breach any obligation of Tenant hereunder, Landlord may, at its option, consider such anticipatory repudiation a breach and material default of this Lease. In addition to any other remedies available to it hereunder or at law or in equity, Landlord may retain all Base Annual Rent, Additional Rent and other sums paid by Tenant hereunder, including any security deposit, if any, to be applied to damages of Landlord incurred as a result of such repudiation, including, without limitation, all damages and remedies reserved to Landlord in this Section 12 or elsewhere in this Lease, as applicable. 12.7 Tenant Abandonment of Demised Premises. --------------------------------------- (a) Abandonment. If the Demised Premises or a substantial portion thereof ------------ shall be deserted or vacated by Tenant for thirty (30) consecutive days or more and Tenant shall be delinquent in the payment of any Base Annual Rent, Additional Rent or other sums due under this Lease, or in the performance of any of Tenant's other obligations hereunder beyond the expiration of applicable notice and cure periods, Landlord may deem the Tenant to have abandoned the Demised Premises, notwithstanding the fact that Tenant may have left all or some part of Tenant's Property thereon. In such event Landlord may consider Tenant in default under this Lease and may pursue all remedies available to it under this Lease or otherwise as may be available in equity or at law. (b) Landlord Right to Enter and to Relet. If Tenant abandons the Demised ------------------------------------- Premises as set forth in subsection (a) above, Landlord may, at its option, enter into the Demised Premises without being liable for any prosecution therefor or for damages by reason thereof. In addition to any other remedy elsewhere provided in this Section 12 or at law or in equity, Landlord, as agent of Tenant, may relet the whole or any part of the Demised Premises for the whole or any part of the then unexpired Lease Term. For the purposes of such reletting, Landlord may make any alterations or modifications of the Demised Premises considered desirable in its sole judgment. 12.8 Tenant's Property. Tenant shall not remove any of Tenant's Property ------------------ from the Demised Premises without the prior written consent of Landlord, other than in the ordinary course of Tenant's business. In the event of a default under this Lease, Tenant shall not, under any circumstances, remove Tenant's Property from the Demised Premises and Landlord may (but shall not be obligated to) keep Tenant's Property in place (and require Tenant to return or replace Tenant's Property to the extent Tenant removes same in violation of the terms of this Lease) and use, or permit another occupant of the Demised Premises, Building and/or Complex to use, Tenant's Property during the remainder of the Least Term (whether or not Landlord elects to terminate this Lease for such default) at no cost, expense or liability to Landlord or such occupant. If Tenant abandons the Demised Premises as defined in Section 12.7(a) above or otherwise vacates the Demised Premises or otherwise defaults under this Lease, any property that Tenant leaves within or related to the Demised Premises shall be deemed to have been abandoned and, without liability to Tenant, may be disposed of in the trash or retained by Landlord as the property of Landlord or disposed of at public or private sale, or placed at the use of another occupant in the Building or the Complex or any subsequent occupant in the Demised Premises, as Landlord sees fit in its sole discretion, all at no cost or expense to Landlord or such other person permitted to use all or a portion of Tenant's Property hereunder, or Landlord may store Tenant's Property at a location selected by Landlord in its sole discretion at Tenant's sole cost and expense. The proceeds of any public or private sale of Tenant's Property shall be applied by Landlord against (i) the expenses of Landlord for removal, storage or sale of the property; (ii) the arrears of Base Annual Rent, Additional Rent or other sums then or thereafter payable under this Lease; and (iii) any other damages to which Landlord may be entitled hereunder. At Landlord's option, at any time during the Lease Term after default by Tenant, Landlord may require Tenant to forthwith remove Tenant's Property from the Demised Premises. If Tenant vacates or abandons the Demised Premises, as defined above, Landlord may transfer any of Tenant's Property to creditors of Tenant, on presentation of evidence of a claim valid on its face of ownership or of a security <PAGE> interest in any of Tenant's Property abandoned in the Demised Premises or the Building, and Landlord may recover any costs incurred by Landlord in doing so, all without incurring any liability to Tenant. 12.9 Landlord's Lien. ---------------- (a) Rights of Distress/Landlord's Lien. To secure the payment of all ----------------------------------- Base Annual Rent, Additional Rent and all other charges and sums that may become due to Landlord under the terms of this Lease, Landlord shall have and is hereby granted by Tenant a right of distress for rent, and a contractual first lien and security interest upon the all Leasehold Improvements, and also upon all proceeds from the sale, transfer or other disposition of any such property, and any replacements and substitutions thereof, and proceeds thereof, and all proceeds of any insurance which may accrue to Tenant by reason of damage to or destruction of any such property. All exemption laws are hereby waived by Tenant. This lien is given in addition to Landlord's statutory and common law liens and shall be cumulative thereto. "Leasehold Improvements" shall be defined to mean all improvements installed or constructed within the Demised Premises whether by or on behalf of either Landlord or Tenant (exclusive of Tenant's trade fixtures and any of Tenant's Property, as below defined), and as repaired, replaced, altered or improved from time to time during the Lease Term, including without limitation, any partitions, wall coverings, floors, floor coverings, ceilings, lighting fixtures other improvements. "Tenant's Property" shall be defined to mean all of Tenant's trade fixtures and all of Tenant's personal property, including but not limited to, all goods, wares, merchandise, inventory, furniture, machinery, equipment, telecommunications and data transmission systems (and all their components exclusive of wiring), business records, accounts receivables and other personal property of Tenant in or about the Demised Premises or that may be placed or kept therein during the Lease Term. 12.10 Injunctive Relief. In the event of a breach by Tenant of any of the ------------------ covenants or provisions hereof, Landlord shall have the right of injunction and the right to invoke any remedy allowed at law or in equity as if re-entry, summary proceedings and other remedies were not herein provided; and in such event Landlord shall be entitled to recover from Tenant, payable as Additional Rent hereunder, any and all reasonable expenses as Landlord may incur in connection with its efforts to secure such injunctive relief or other remedy at law or in equity, including all costs and reasonable attorneys' fees. 12.11 Independent Covenants. If Landlord shall commence any proceeding ---------------------- based upon non-payment of Base Annual Rent, Additional Rent or any other sums of any kind to which Landlord may be entitled or which it may claim hereunder, Tenant will not interpose any counterclaim, set-off, recoupment or other defense of any nature or description in any such proceeding absent mandatory counterclaims or defenses. The parties hereto specifically agree that Tenant's covenants to pay Base Annual Rent, Additional Rent and any other sums required hereunder are independent of all other covenants and agreements of Landlord herein contained; provided, however, that this shall not be construed as a waiver of Tenant's right to assert such a claim in any separate action brought by Tenant. Tenant further waives any right or defense which it may have to claim a merger. 12.12 Waiver of Redemption. Tenant hereby expressly waives any and all --------------------- rights of redemption granted by or under any present or future laws in the event of Tenant being evicted or dispossessed for any cause, or in the event of Landlord obtaining possession or a judgment for or other right to possession of the Demised Premises and/or Tenant's Property by reason of the violation by Tenant of any of the covenants and conditions of this Lease, or otherwise. 12.13 Attorneys' Fees. The parties hereto agree that wherever in this ---------------- Lease the Landlord is entitled to collect its "attorneys' fees", Landlord shall be entitled to collect reasonable attorneys' fees actually incurred in enforcing its rights hereunder in the event Landlord is the prevailing party. Similarly, Tenant shall be entitled to collect its reasonable attorneys' fees actually incurred in enforcing its rights hereunder in the event Tenant is the prevailing party. 13. SUBORDINATION 13.1 Subordination. This Lease is subject and subordinate to all ground or -------------- underlying leases and to all mortgages and/or deeds of trust and/or other security interests (individually and collectively "mortgage") which may now or hereafter affect the real property of which the Demised Premises form a part, including all renewals, modifications, consolidations, replacements and extensions thereof. This clause shall be self-operative and no further instrument of subordination shall be required to effect this subordination. Notwithstanding the foregoing, in confirmation of such subordination, Tenant shall at Landlord's request execute and deliver to Landlord within ten (10) business days after Landlord's request, any requisite or appropriate certificate, subordination agreement or other document that may be reasonably requested by Landlord or any other party requiring such certificate, subordination agreement or document. If Tenant fails to execute such certificate, subordination agreement or other document requested by Landlord or other party within said ten (10) day period, Tenant by such failure, irrevocably constitutes and appoints Landlord as its special attorney-in-fact to execute such certificate, subordination agreement or other document on Tenant's behalf, the foregoing power of attorney being deemed coupled with an interest. Notwithstanding the foregoing, any lessor under any ground or underlying lease and the party secured by any mortgage affecting the real property of which the Demised Premises are a part, or any renewal, modification, consolidation, replacement or extension thereof, shall have the right to recognize this Lease and, in the event of any cancellation or termination of such ground or underlying lease, or any foreclosure under any mortgage, or any sale of the real property at foreclosure sale, or any transfer of the real property by a deed in lieu of foreclosure, this Lease shall continue in full force and effect at the option of the lessor under such ground or underlying lease or, as applicable, the party secured by such mortgage, or the purchaser at any foreclosure sale, or the party taking the real property under a deed in lieu of foreclosure, such party being hereby authorized by Tenant to exercise such option to cancel or continue this Lease in such party's reasonable or unreasonable discretion. Tenant hereby consents to <PAGE> the right of such party to effect the survival of this Lease. Tenant agrees that neither the cancellation nor termination of any ground or underlying lease, nor the foreclosure under any mortgage, nor the sale at foreclosure, nor the transfer by a deed in lieu of foreclosure, shall, by operation of law or otherwise, result in cancellation or termination of this Lease or the obligations of Tenant hereunder, except in the sole option of the party herein granted such option, which option may be exercised in said party's reasonable or unreasonable discretion. 13.2 Estoppel Certificates. Tenant shall execute and return within ten ---------------------- (10) business days any certificate that Landlord may request from time to time, stating that this Lease is unmodified and in full force and effect, or in full force and effect as modified, and stating the modification. The certificate also shall state (a) the amount of the monthly installment of Base Annual Rent and Additional Rent and the dates to which such rent has been paid in advance; (b) the amount of any security deposit or prepaid rent; (c) is not aware of any default on the part of Landlord nor is there in existence any condition, event, act or omission which with the giving of notice and/or the passage of time will constitute a default on the part of Landlord, or attach a memorandum stating in detail the factual circumstances of such default and/or the basis under the Lease for such default; (d) that Tenant is not aware of any right to set-off or recoupment and no defense or counterclaim against enforcement of its obligations under this Lease; (e) that Tenant has no other notice of any sale, transfer or assignment of this Lease or of the rentals; (f) that all Construction Improvements and other work and improvements required of Landlord has been completed and that the Construction Improvements and other work and improvements are complete and satisfactory; (g) that Tenant is in full and complete possession of the Demised Premises; (h) the date on which Tenant's rental obligations commenced (excluding any periods of abatement) and the date to which such rent has been paid; (i) that Tenant has not advanced any amounts to or on behalf of Landlord which have not been reimbursed; (j) that Tenant understands that this Lease has been collaterally assigned to Landlord's mortgagee as security for a loan to Landlord; (k) that Base Annual Rent and Additional Rent may not be prepaid more than one (1) month in advance without the prior written approval of Landlord's mortgagee; and (l) such other items as Landlord may reasonably request. Failure to deliver the certificate within the aforesaid ten (10) business day period shall be conclusive upon Tenant for the benefit of Landlord and any successor to or mortgagee or assignee of Landlord that this Lease is in full force and effect and has not been modified except as may be represented by the party requesting the certificate. If Tenant fails to deliver the certificate within the aforesaid ten (10) business day period, Tenant by such failure irrevocably constitutes and appoints Landlord as its special attorney-in-fact to execute and deliver the certificate to any third party, the foregoing power of attorney being deemed to be coupled with an interest. 13.3 Attornment. Tenant covenants and agrees that, in the event any ground ----------- lessor, lessor of any underlying lease or subsequent purchaser of the Building so requests or in the event of any foreclosure under any mortgage, or any renewal, modification, consolidation, replacement or extension thereof, or in the event of a sale at foreclosure, or in the event of any acceptance of any deed in lieu of foreclosure, which may now or hereafter affect the real property of which the Demised Premises are a part, Tenant shall attorn to any ground lessor, lessor of any underlying lease or subsequent purchaser of the Building or to the party secured by such mortgage, or any renewal, modification, consolidation, replacement or extension thereof, and to any purchaser at any foreclosure sale or party taking a deed in lieu of foreclosure, and at the sole option of such party, which option may be exercised in said party's reasonable or unreasonable discretion, this Lease shall continue as a direct lease between Tenant herein and such landlord or its successor. In any case, such landlord or successor under such ground or underlying lease or such secured party or purchaser at foreclosure sale or party taking a deed in lieu of foreclosure shall not be bound by any prepayment on the part of Tenant of the Base Annual Rent or Additional Rent for more than one month in advance, so that Base Annual Rent and Additional Rent shall be payable under this Lease in accordance with its terms, from the date of the termination or transfer of the ground or underlying lease or the foreclosure under such mortgage, or the date of foreclosure sale or transfer by deed in lieu of foreclosure, as if such prepayment had not been made. Further, such landlord or successor in interest shall not be liable for damages for any act or omission of Landlord or any prior landlord or be subject to any recoupments, offsets, counterclaims or defenses which Tenant may have against Landlord or any prior landlord. Tenant shall, upon request of such landlord or successor landlord, execute and deliver an instrument or instruments confirming Tenant's attornment. 13.4 Mortgagee Rights. ----------------- (a) Mortgagee Requirements. Tenant shall, at its own expense, comply with ----------------------- all reasonable notices of Landlord's mortgagee or other financial institution providing funds which are secured by a mortgage placed on the whole or any part of the real property of which the Demised Premises are a part, respecting all matters of occupancy, use, condition or maintenance of the Demised Premises, provided the same shall not unreasonably interfere with the conduct of Tenant's business materially limit or affect the rights of the parties under this Lease. Tenant shall, if so directed by Landlord's mortgagee or such other financial institution in writing, pay all Base Annual Rent, Additional Rent and other sums owed to Landlord directly to such mortgagee or other financial institution. Notwithstanding acceptance and execution of this Lease by the parties hereto, the terms hereof shall be automatically deemed modified, if so required, for the purpose of complying with or fulfilling the reasonable requirements of any mortgagee or trustee named or secured by a mortgage that may now or hereafter be placed upon or secured by the real property of which the Demised Premises are a part or any part thereof, or any other financial institution providing funds to finance or refinance the real property of which the Demised Premises are a part; provided, however, that such modification(s) shall not be in material derogation or diminution of any of the rights of the parties hereunder, nor materially increase any of the obligations or liabilities of the parties hereunder. (b) Notices to Mortgagee. Tenant agrees to give Landlord's mortgagee and --------------------- any trustee named or secured by a mortgage a copy of any notice of default served upon Landlord by Tenant, provided that prior to such notice Tenant has been notified in writing (by way of Notice of Assignment of Rents and Leases, or otherwise) of the names and addresses of such mortgagees and trustees. Notice shall be provided to the mortgagees and trustees in the manner prescribed in Section 24. Tenant further agrees that if Landlord shall have failed to cure such default within <PAGE> the cure period provided in this Lease, if any, then the mortgagees and trustees shall have an additional thirty (30) days within which to cure such default, or if such default cannot be cured within that time, then such additional time as may be necessary if within such thirty (30) days such mortgagee or trustee has commenced and is diligently pursuing the remedies necessary to cure such default (including, but not limited to, commencement of foreclosure proceedings if necessary to effect such cure), in which event Tenant shall not pursue its remedies while such cure is being diligently pursued. 13.5 Non-disturbance. As a condition to Tenant's subordination of this Lease --------------- as provided in the Lease, Landlord agrees to provide Tenant with evidence that Landlord's mortgagee or ground lessor will recognize this Lease, notwithstanding any foreclosure or termination of its mortgage or ground lease. Landlord shall deliver to Tenant a non-disturbance agreement evidencing same within thirty (30) days after execution hereof, and similar agreements from any future mortgagees or ground lessor. 14. TENANT'S HOLDOVER 14.1 With Landlord Consent. If Tenant continues, with the knowledge and ---------------------- written consent of Landlord obtained at least thirty (30) days prior to the expiration of the Lease Term, to remain in the Demised Premises after the expiration of the Lease Term, then Tenant shall, by virtue of said holdover agreement, become a tenant from month-to-month at the rent stipulated by Landlord in said consent, or if none is stipulated, at the monthly rate of Base Annual Rent and Additional Rent last payable under this Lease (adjusted in accordance with the provisions of this Lease as if the holdover period were originally included herein), commencing said monthly tenancy with the first day next following the end of the Lease Term. All other terms and conditions of this Lease shall apply to any holdover period(s). Tenant shall give to Landlord at least thirty (30) days written notice of any intention to quit the Demised Premises. Tenant shall be entitled to thirty (30) days written notice from Landlord to quit the Demised Premises, except in the event of nonpayment of the monthly installment of Base Annual Rent and/or Additional Rent in advance or of the breach of any other covenant, term or condition of this Lease by Tenant, in which event Tenant shall not be entitled to any notice to quit, the usual thirty (30) days notice to quit being hereby expressly waived by Tenant. 14.2 Without Landlord Consent. In the event that Tenant, without the ------------------------- written consent of Landlord, shall hold over beyond the expiration of the Lease Term, then Tenant hereby waives all notice to quit and agrees to pay to Landlord for the period that Tenant is in possession after the expiration of this Lease, a monthly charge which is one and one-half times the total monthly installment of Base Annual Rent and Additional Rent in effect during the last month of the Lease Term. Tenant expressly agrees to reimburse, defend, indemnify and hold Landlord and Landlord's Agent harmless from all loss and damages which Landlord or Landlord's Agent may incur in connection with or in defense of claims by other persons or entities against Landlord, Landlord's Agent or otherwise arising out of the holding over by Tenant, including without limitation reasonable attorneys' fees which may be incurred by Landlord or Landlord's Agent in defense of such claims. Acceptance of Base Annual Rent, Additional Rent or any other sums due from Tenant hereunder or the performance by Tenant of its obligations hereunder subsequent to the expiration of the Lease Term, shall not constitute consent to any holding over. Landlord shall have the right to apply all payments received after the expiration date of the Lease Term toward payment for use and occupancy of the Demised Premises subsequent to the expiration of the Lease Term and toward any other sums owed by Tenant to Landlord, regardless of how such payment(s) may be designated by Tenant. Landlord, at its option, may forthwith re-enter and take possession of the Demised Premises in accordance with legal process. Notwithstanding the foregoing, if Tenant holds over, without Landlord's written consent, due to acts of God, riot, or war, then such holdover shall be at the total monthly installment of Base Annual Rent and Additional Rent applicable to the last month of the Lease Term (adjusted in accordance with the provisions of this Lease as if the holdover period were originally included herein), for the duration of the condition (but not to exceed ten (10) days), but such continued occupancy shall not create any renewal of the term of this Lease nor shall it create a tenancy from year-to-year, month-to-month, or otherwise, and Tenant shall be liable for and shall indemnify, defend and hold harmless Landlord and Landlord's Agent against any loss and damages suffered by Landlord or Landlord's Agent as described above. Any holdover period during which the Landlord and Tenant are negotiating the terms and conditions of any holdover tenancy, new lease or other matter, and/or for which Landlord and Tenant have failed to reach an agreement as to the rent to be paid during such holdover period, shall conclusively be deemed to be a holdover without the consent of Landlord for the purpose of determining the rental to be paid and the obligations to be performed by Tenant during such period. 15. SECURITY DEPOSIT - Intentionally Omitted 16. QUIET ENJOYMENT So long as Tenant shall observe and perform the covenants and agreements binding on Tenant hereunder, Tenant shall at all times during the term herein granted, peacefully and quietly have and enjoy possession of the Demised Premises without any encumbrance or hindrance by, from or through Landlord, except as provided for elsewhere under this Lease. Nothing in this Section shall prevent Landlord from performing alterations, improvements or repairs on other portions of the Building not leased to Tenant or from performing alterations, improvements or repairs within the Demised Premises in accordance with the provisions of this Lease, nor shall performance of alterations, improvements or repairs by Landlord, Landlord's Agent or any other Tenant of the Building be construed as a breach of this covenant by Landlord. 17. SUCCESSORS <PAGE> All rights, remedies and liabilities herein given to or imposed upon either of the parties hereto, shall extend to their respective heirs, executors, administrators, personal representatives, successors and assigns. This provision shall not be deemed to grant Tenant any right to assign this Lease or to sublet the Demised Premises. 18. WAIVER OF JURY TRIAL AND STATUTE OF LIMITATIONS Landlord and Tenant (and any guarantors and other parties with liability for the performance of any or all of Tenant's obligations hereunder, as well as any subtenants, assignees and licensees of Tenant) hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other or in respect of any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant hereunder, Tenant's use or occupancy of the Demised Premises, and/or any claim of injury or damage. Tenant (and any guarantors and other parties with liability for the performance of any or all of Tenant's obligations hereunder, as well as any subtenants, assignees and licensees of Tenant) hereby agrees to submit to the personal jurisdiction of any court of competent jurisdiction within the state, or the District of Columbia if applicable, in which the Demised Premises and/or Landlord's principal place of business is located. 19. LIMITATION OF LANDLORD'S LIABILITY; NOTICE 19.1 Landlord's Consent. Notwithstanding anything to the contrary ------------------- contained in this Lease, if any provision of this Lease expressly or impliedly obligates Landlord not to unreasonably withhold its consent or approval, Landlord agrees that it shall comply with such provisions in accordance with standards used by other Landlord's of comparable office buildings within Washington, D.C. 19.2 Individual Liability. Tenant acknowledges and agrees that the --------------------- liability of Landlord with respect to any claim arising out of, related to, or under this Lease shall be limited solely to its interest in the Building. No personal judgment shall lie against the Landlord nor any partner of a partnership constituting Landlord (if Landlord is a partnership) nor any shareholder of Landlord (if Landlord is a corporation), and none of the same will be personally liable with respect to any claim arising out of or related to this Lease. If the Landlord is a partnership, any deficit capital account of any partner and any partner's obligation to contribute capital shall not be deemed an asset of the partnership. In the event of sale or other transfer of the Landlord's interest in the Demised Premises and/or Building, Landlord shall thereupon and without further act by either party be deemed released from all liability and obligations hereunder arising out of any act or omission relating to the Demised Premises, the Building or this Lease, occurring subsequent to the sale or other transfer. The provisions hereof shall inure to the benefit of Landlord's successors and assigns, including any mortgagee or trustee under a deed of trust. The foregoing provisions are not intended to relieve Landlord from the performance of any of Landlord's obligations under this Lease, but only to limit the personal liability of Landlord, and its partners or shareholders, as the case may be; nor shall the foregoing be deemed to limit Tenant's rights pursuant to this Lease to obtain injunctive relief or specific performance with respect to any obligations of Landlord hereunder. Notwithstanding any provisions to the contrary, in no event shall Landlord be released from any liability, debt or obligation pertaining to periods during which the particular Landlord owned the Building, nor shall Tenant's right to recover sums from Landlord's policies of insurance maintained with respect to the Building be adversely affected by reason of any limitation of Landlord's liability or similar provisions contained in the Lease. 19.3 Notice in Event of Landlord's Default. Notwithstanding anything to -------------------------------------- the contrary in this Lease, in no event shall Landlord be deemed to be in default in the performance of any covenant, condition or agreement herein contained unless Tenant shall have given Landlord written notice of such default, and Landlord shall have failed to cure such default within thirty (30) days after such notice (or if such default is of such nature that it cannot be completely cured within said thirty (30) days, if Landlord fails to commence to cure within said thirty (30) days and thereafter proceed with reasonable diligence and in good faith to effect such cure). 20. AUTHORITY Landlord and Tenant hereby covenant each for itself, that each has the full right, power and authority to enter into this Lease upon the terms and conditions herein set forth. If Tenant signs as a corporation, each of the persons executing this Lease on behalf of Tenant does hereby covenant and warrant that Tenant is and shall be throughout the Lease Term, a duly authorized and existing corporation, qualified to do business in the jurisdiction in which the Demised Premises are located and is in good standing, that the corporation has full right and authority to enter into this Lease, and that each of the persons signing on behalf of the corporation were authorized to do so.

SEVERABILITY The unenforceability, invalidity, or illegality of any provision herein shall not render any other provision herein unenforceable, invalid, or illegal. 30.

For purposes hereof, the terms "Landlord", "Landlord's Agent", "Tenant", "Complex", "Building", "Demised Premises", "Tenant's Property" and "Systems" are defined in the Lease to which these rules and regulations are attached. Wherever these terms appear in the rules and regulations they shall have the same meaning as defined in the Lease. 20. These Rules and Regulations are in addition to, and shall not be construed to in any way modify or amend, in whole or in part, the agreements, covenants, conditions and provisions of any lease of any premises in the Building except to the extent the Lease expressly reflects the right of Tenant to do otherwise. Exhibit C - Page 2 <PAGE> Exhibit C - Page 3 <PAGE> EXHIBIT F CONSTRUCTION OF PREMISES 1.2 (a) Notwithstanding any provision in the Lease to the contrary, Tenant will cause its contractor, Salameh Construction or such other contractor reasonably acceptable to Landlord to construct the "Construction Improvements" (as such term is defined in the Lease) to the demised premises. The Construction Improvements are referred to herein as the "Tenant Improvement". Both parties recognize that in order to have the demised premises substantially completed as soon as practicable, it is essential that the procedures set forth herein be expeditiously implemented and adhered to, and that plans and specifications for Tenant's Improvements be prepared as early as reasonably practicable so as to enable the mutually agreed upon contractor to complete such work promptly and at the lowest possible cost to Landlord and Tenant. Accordingly, Tenant agrees to furnish Landlord with its space plan ("Space Plan") prepared by Dennis Burns of Burns & Associates (the "Architect") including final partition and other layout requirements, telephone and electrical requirements, lighting, finish selections, equipment specifications, and any special items for the demised premises on or before December 16, 1998. The Space Plan shall be subject to approval by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed and shall be given within five (5) business days. If Landlord does not respond within said five (5) business day period, Tenant shall send Landlord a second written request for approval and if Landlord fails to respond within three (3) business days following the second request, it shall be deemed that Landlord has approved the Space Plan. Upon approval of the Space Plan by Landlord, Tenant shall cause the Architect to prepare and submit to Landlord for approval detailed plans, specifications and working drawings (the "Plans") for the construction of Tenant's Improvements to the demised premises. Such Plans shall be delivered to Landlord for its approval by Tenant on or before January 12, 1999. Such Plans shall be full permit ready Plans complete with pricing notes. Landlord acknowledges that Tenant shall use the Plans to obtain all permits and approvals which are necessary to construct Tenant's Improvements. Tenant shall apply for the required Building permit(s) as soon as practicable following approval of the plans and specifications by Landlord and thereafter diligently process such application. After approval of the Plans by Landlord, which approval shall not be unreasonably withheld, delayed or conditioned, no further changes to the Plans shall be made without the prior written approval by the Landlord unless expressly below set forth in the case of re-pricing changes. As used herein, the term "Tenant's Improvements" shall include all work to be done in the demised premises pursuant to the Plans including, but not limited to: partitioning, doors, ceiling, floor covering, wall finishes (including paint and wall coverings), window coverings, electrical (excluding plumbing), heating ventilating and air conditioning, fire protection, cabinets and other millwork. Tenant acknowledges that Landlord's review and approval of the Plans is not conducted for the purposes of determining the accuracy and completeness of the Plans, or compliance with applicable codes and governmental regulations including the Americans With Disabilities Act ("ADA") or their sufficiency for purposes of obtaining a building permit, all of which remain the responsibility of Tenant and Architect. Accordingly, except as otherwise provided herein, Landlord shall not be responsible for any delays in obtaining a building permit, all of which remain the responsibility of Tenant and Architect. Accordingly, except as otherwise provided herein, Landlord shall not be responsible for any delays in obtaining the building permit due to the insufficiency of the Plans or any delays due to changes in the Plans required by the applicable government or regulatory agencies reviewing the Plans which such delay shall be deemed Tenant delay. Upon approval of the Plans, Tenant shall have the final approved Plans competitively priced. However, by reason of the time frames involved, Tenant may not necessarily select the lowest bidder. Said contractors shall provide Landlord and Tenant with final estimated bids (the "Cost Breakdown") for completion of the Tenant Improvements which such bids shall include, without limitation, construction cost of the Improvements, sales and use taxes, testing and inspection costs and construction fees. The Cost Breakdown shall identify potential long-lead items, if any. Within five (5) business days after receipt by Tenant of the Cost Breakdown, Tenant shall either approve the same in writing or shall provide Landlord with a detailed list of revisions to the approved Plans acceptable for repricing, including any necessary modifications to the Plans to enable such repricing. Any time delay incurred in the approval of the Cost Breakdown due to Tenant's failure to approve the same in writing or to submit its revisions within such five (5) business day period shall constitute Tenant delay. Tenant shall incorporate the suggested revisions and deliver such revisions or modifications to Tenant within five (5) business days. Within five (5) days following receipt by Tenant of such revisions or modifications, Tenant shall give its written approval with respect thereto or shall request other revisions or modifications therein, and any time delay incurred with the approval of the Cost Breakdown from the date of the second notice of this approval shall constitute Tenant delay. (b) Construction will be performed by the contractor designated by Tenant. Landlord will provide Tenant with a construction allowance of Twenty-Four and 62.5/100 Dollars ($24.625) per rentable square feet of space on the Fourth and Sixth Floor (them "Construction Allowance") (i.e $25.00 less a $.375 per square foot construction management fee). The Construction Allowance may be used for all phases of Tenant's Improvement, including for Tenant's space planning, design and construction plans provided that at least $17.625 of the $24.625 per square foot Construction Allowance is devoted to hard and soft costs of construction and/or provision of the supplemental HVAC and/or supplemental sprinkler system, as well as costs not in excess of $3.00 per square foot to bring fiber optic cable to the Premises and Building). Tenant shall be entitled to be reimbursed any portion or portions of the $17.625 per square foot portion at anytime during the Lease Term, and to the extent the $17.625 per square foot portion is not expended by Tenant with respect to the Tenant Improvements, Tenant shall be free to use such portion towards construction costs incurred with respect to any subsequent alterations or installations made at the Premises by Tenant. Any unused portion of the Construction Allowance, not in excess of $7.00 per square foot, can be used by Tenant against the first rentals otherwise payable under this Lease at anytime from and after the Commencement Date and/or costs to obtain Wiring and Cabling, fiber optic cable, or electric to or at the Premises, and/or Tenant's generator. Landlord agrees to disburse the Construction Allowance on a monthly basis directly to the general contractor or others as directed by Tenant on Exhibit F Page 1 <PAGE> account of work performed, or in the event Tenant has paid the requested amount itself directly to such contractor or other party, Landlord shall reimburse Tenant the portion of the Construction Allowance to which Tenant is then entitled, based upon paid receipts submitted to Landlord. Tenant shall provide a proposed monthly requisition no later than the twenty-fifth (25th) day of the calendar month preceding the month in which Tenant requests such disbursement in order to permit Landlord to process Tenant's request by the tenth (10th) day of the following month. (c) The Lease Commencement Date shall be determined in Paragraph 1.2 (a) of this Lease, except that if the demised premises are not substantially completed through no fault or delay occasioned by Tenant the same shall not be considered a default by Landlord and, the sole remedy shall be that the Lease Commencement Date shall be delayed until the earlier of (i) the date identified in written notice to Tenant as the date that the demised premises was or will be substantially completed or (ii) the date which is identified in written notice to Tenant as the date that the demised premises would have been substantially completed if not for the delays set forth below in subsection (e). The assumption of possession of the demised premises by Tenant shall constitute an acknowledgment by Tenant that the demised premises are in good condition and the work done by Landlord therein is satisfactory and accepted in their then "as is" condition subject to punchlist items. For purposes herein, "substantially completed" shall be in Section 3.1 (c). (d) Landlord and Tenant each acknowledge that any delays on its part in submitting requirements and reviewing and approving plans or prices and any changes requests made by Tenant may affect the timely completion of the demised premises. In the event of any Tenant delay beyond the time periods called for in this Exhibit, any resulting delay in the completion of construction of the demised premises shall be at Tenant's sole cost and expense, and Tenant shall pay to Landlord an amount equal to one thirtieth (1/30th) of the Base Annual Rent due for the first full calendar month of the Term for each day of Tenant delay if the demised premises would have been substantially completed by such date but for the Tenant delay. In the event of any Landlord delay beyond the time periods called for in this Exhibit, the Lease Commencement Date shall be postponed on a one and one-half (1.5) days for each day of delay. The Lease Commencement Date shall not be extended due to Tenant delay. Punchlist items shall not affect the Lease Commencement Date. (e) Landlord and Tenant expressly agree that possession of the Demised Premises shall be tendered promptly following execution of this Lease to commence construction, subject to Tenant's compliance with the Landlord's approval rights above. Possession shall be delivered to Tenant in "as-is" condition, with any supplemental equipment (electric, mechanical, HVAC, generators, etc.) presently located in the Demised Premises being tendered to Tenant. Notwithstanding any provision either in the Lease or this Exhibit to the contrary, Landlord and Tenant further expressly agree that Tenant will occupy at least one-half of the Premises following substantial completion of the initial portion of the demised premises occupied by Tenant (i.e the "Initial Substantial Completion Date"), and to defer completion (and rent commencement) on the remaining portion (the "Remaining Portion") for a period not in excess of one and one-half (1.5) months. However, within one month from the Initial Substantial Completion Date, Tenant shall commence payment of rent on no less than 75% of the entire demised premises, with Tenant to pay rent on the entire Premises no later than expiration of one and one-half months following the Initial Substantial Completion Date. Tenant shall be permitted the right to commence beneficial use and occupancy (i.e. place personnel within conducting business operations therein as opposed to placement of furniture, fixtures or equipment) of any part or parts of the Remaining Portion as Tenant determines, and rent shall not commence on any particular part of the Remaining Portion until such beneficial use shall occur (prior to expiration of the aforesaid one and one-half month period). Nothing contained herein shall be deemed to limit the rights of Tenant to defer rent commencement on the portion of the fourth floor presently occupied by GSA should GSA fail to surrender such premises by December 15, 1998.
