EXHIBIT 10.7 ------------ LEASE by and between AETNA LIFE INSURANCE COMPANY and TELEPHONE BUSINESS MEETINGS, INC. dba ACCESS CONFERENCE CALL RIDER ----- The printed part of the Lease is hereby modified and supplemented as follows. Wherever there is a conflict between this Rider and the printed part of the Lease the provisions of this Rider are paramount and the Lease shall be construed accordingly. 1. The following language is hereby added to the Lease: Renewal Option. -------------- 1.1 Tenant is granted the right and option (the "Renewal Option") to extend the term of this Lease for one (1) additional period of five (5) years, and if such renewal is effectively exercised, such renewal term (the "Renewal Term") shall commence upon the expiration of the previous term of this Lease, provided that: (a) Such option must be exercised, if at all, by notice from Tenant to Landlord given at least one hundred eighty (180) days prior to the expiration of the Lease Term; and (b) At the time of exercising such option, this Lease shall be in full force and effect and there shall exist no default by Tenant which remains uncured beyond any applicable period of grace. 1.2 In the event the foregoing option is effectively exercised, all the terms and conditions contained in this Lease shall continue to apply except that: (a) There shall be no further right of renewal beyond the period referred to above; (b) The Renewal Option shall apply to all (and not less than all) of the Premises originally leased hereunder, plus any additional space leased by the Tenant pursuant to any option contained herein or otherwise: (c) In the event Tenant shall have assigned this Lease or sublet in excess of twenty-five percent (25%) of the Premises, except to an affiliate as permitted in the Lease, this Renewal Option shall automatically expire and be null and void with respect to that portion of the Premises so assigned or sublet; (d) The rental rate applicable to the Premises during any Renewal Term, plus any additional space then leased pursuant to Tenant shall enter into an amendment to this Lease to set forth the amount of initial Rent during such Renewal Term. (e) The Rent during each such Renewal Term shall be ninety-five percent (95%) of the then current fair market rental rate for similar buildings in the same geographic area including all applicable market concessions and rental escalations. If Landlord and Tenant are unable to reach agreement on the current fair market rental rate for the Premises within ten (10) business days after Tenant's written notice to Landlord of such renewal, then such determination shall be made using the three broker method as follows: within ten (10) business days after expiration of the ten (10) business day period for Landlord and Tenant to reach mutual agreement as contemplated above, Landlord and Tenant shall each select a commercial real estate broker who is licensed and in good standing in the Commonwealth of Virginia, who has at least five (5) years experience, and who is knowledgeable about the Reston area and commercial leasing therein. To determine the current fair market rental rate, the brokers shall consider comparable office leases in the Reston area and shall compare all relevant factors including (1) the age, quality, function, location and condition of the Building; (2) the time period covered by the relevant Renewal Term; (3) the amount of space being leased under the comparable leases as compared to the amount of space within the Premises; and (4) market concession such as, but not limited to, rental abatement and comparable tenant improvement allowances for renewals and new leases (as the case may be). Such brokers shall also make appropriate adjustments in their calculation to account for any costs or expenses (or savings) which relate to the inclusion or exclusion of specific operating costs items (i.e., cost of electricity, etc.) and different base years which may be applicable to such full service lease(s), or which are unique to the particular comparable office leases in those Reston office buildings used in arriving at their calculation of the current fair market rental rate for the Premises as set forth above. If Landlord's broker and tenant's broker are unable to agree upon the current fair market rental rate for the Premises within thirty (30) days of their selection, they shall mutually select a similarly qualified third (3rd) broker, and the third (3rd) broker shall determine the current fair market rental rate for the Premises. If the determination of the third broker falls between the determination of Landlord's broker and Tenant's broker, the Rent during the Renewal Term shall be ninety-five percent (95%) of the third broker's determination of the current fair market rental rate for the Premises. However, if the determination of the third broker does not fall between the determinations of Landlord's broker and Tenant's broker, the Rent during the Renewal Term shall be ninety-five percent (95%) of the average of the two closest brokers' determinations. 1.3 In the event Tenant fails to exercise the foregoing option in the manner and within the time period set forth herein, the Lease shall automatically terminate at the end of the then current term, the applicable Renewal Option shall lapse and Tenant shall have no further right or option to extend the term of this Lease. 2. The following language is hereby added to the Lease: 2 2.1 Early Termination Option #1. Tenant may terminate this Lease as of the --------------------------- seventy-second (72nd) month of the term by: (1) providing Landlord with not less than 180 days written notice of its intent to terminate, and (2) providing a payment of $15.07 per square foot of the Premises, fifty percent (50%) of which shall be due upon Tenant's delivery of its notice of termination, and fifty percent (50%) of which shall be due on the date of termination. If the Lease is terminated by Tenant as provided for under this paragraph, then the rights of the parties with respect to said termination will be as provided for under the Lease had the Lease Term expired on the Lease Expiration Date. 2.2 Early Termination Option #2. Tenant may terminate this Lease as of the --------------------------- ninety-sixth (96th) month of the term by: (1) providing Landlord with not less than 180 days written notice of its intent to terminate, and (2) providing a payment of $8.25 per square foot of the Premises, fifty percent (50%) of which shall be due upon Tenant's delivery of its notice of termination, and fifty percent (50%) of which shall be due on the date of termination. If the Lease is terminated by Tenant as provided for under this paragraph, then the rights of the parties with respect to said termination will be as provided for under the Lease had the Lease Term expired on the Lease Expiration Date. 3. The following language is hereby added to the Lease Agreement. Right of First Refusal. Subject to the rights, as of the date of the full ---------------------- execution of this Lease, of existing tenants, Landlord hereby grants to Tenant an on-going right of first refusal ("Right of First Refusal") to lease any space which becomes available for lease (the "Refusal Space") following the full execution of this Lease (subject to the terms set forth below). If Landlord receives a bona fide offer to lease all or any part of the Refusal Space, then Landlord shall deliver written notice of such offer to Tenant (the "Refusal Notice") outlining the material terms of the offer and Tenant shall have the right to exercise the Right of First Refusal upon all of the material terms and conditions set forth in such Refusal Notice, by written notice to Landlord, delivered no later than ten (10) business days after Landlord's delivery to Tenant of the Refusal Notice. Included with Tenant's written response to the Refusal Notice (if positive) shall be current financial statements. After reviewing these statements, Landlord reserves right to request such credit enhancements as Landlord deems reasonable given the rent for the space to be leased (and with no such enhancements to be required unless Tenant's financial condition has materially deteriorated since the execution of this Lease). If Tenant fails to exercise its Right of First Refusal, within such ten (10) business day period (time being of the essence), Tenant shall be deemed to have rejected the Refusal Space designated in the Refusal Notice and Landlord shall have the right to lease the Refusal Space to the third party upon effectively the same terms and conditions set forth in the Refusal Notice. In the event Tenant accepts Landlord's offer, Tenant shall execute a new lease for the Refusal Space using the legal terms set forth in this Lease, but modifying the business terms as necessary to conform to the business terms and conditions set forth in the bona fide offer, as reflected in the Refusal Notice. Notwithstanding the foregoing, with respect to the remaining space on the second floor, Tenant shall have, after full Lease execution, an additional two (2) full Lease Year Right of First 3 Refusal at the same terms and conditions of this Lease to include: (i) a Twenty Dollar ($20.00) per square foot Tenant Improvement Allowance ("Improvement Allowance") if Tenant leases the space in the first (1st) year of its term; (ii) a Fifteen Dollar ($15.00) per square foot Improvement Allowance if Tenant leases the space in the second year of its term; and (iii) a pro-rata share of the rental abatement, provided for in Article 1.4 of the Lease (determined by comparing the Lease Term for the Premises to the lease term for the Expansion Space). 4. The following language is hereby added to the Lease: As security for its full and faithful performance of this Lease, Tenant shall pay Landlord a total security deposit of One Hundred Thousand Dollars ($100,000.00) payable within thirty (30) days of the full execution of this Lease. Tenant shall have the right to provide the security deposit to Landlord either in the form of immediately available funds (i.e., cash, certified check, money order) or an irrevocable and transferable letter of credit running in favor of Landlord, with such letter of credit securing Tenant's obligation hereunder subject to the terms and conditions set forth hereinbelow. The security deposit shall not be considered an advance payment of rental or a measure of Landlord's damages in case of default by Tenant. The letter of credit shall be issued by a bank acceptable to Landlord in Landlord's sole but reasonable discretion and under the supervision of the banking commission of the Commonwealth of Virginia, FDIC or FSLIC. If the credit of the bank which originally issues the letter of credit becomes unacceptable to Landlord in Landlord's sole but reasonable discretion, Tenant shall substitute another letter of credit from a bank which is acceptable to Landlord in Landlord's sole reasonable discretion. The letter of credit shall be irrevocable for the period ending no less than one (1) year after the date of issuance. Tenant shall renew the letter of credit and maintain it for the period ending five (5) days after the later of (i) the date of actual termination of this Lease or (ii) the date Tenant shall have vacated and surrendered the entire Premises to Landlord in accordance with the terms hereof and shall provide that it is automatically renewable for said period hereby demised, unless released pursuant to the provisions of this Section or unless the issuing bank delivers a notice of non- renewal no later than thirty (30) days prior to expiration. If Tenant fails to renew the letter of credit within ten (10) business days of its expiration, Landlord may draw upon the letter and maintain the funds as an interest-bearing deposit to be returned to Tenant upon receipt by Landlord of a substitute letter of credit from Tenant. The form and terms of the letter of credit shall be reasonably acceptable to Landlord and shall provide, among other things, in effect that: (a) Landlord ("Beneficiary") shall have the right to draw down an amount up to the then current face amount of the letter of credit after a default by Tenant under the Lease and expiration of the applicable notice and cure period upon presentation to the issuing bank of Landlord's own declaration signed or purportedly signed by or on its behalf reading as follows: i. that the declarant is an officer (or general partner or sole proprietor in the case of a general partnership or sole proprietorship, respectively) of the Beneficiary on behalf of the Beneficiary; 4 ii. that the declarant has authority to make the declaration on behalf of the Beneficiary; iii. that the declaration is made pursuant to the terms of the letter of credit number ____________; iv. that Tenant is in default after expiration of the applicable notice and cure period under the terms of a lease made between Beneficiary and Telephone Business Meetings, Inc., dba Access Conference Call Service; v. that the amount of the default is $_________; and vi. [or in lieu of iv. and v.] that Tenant under the terms of a lease made between Beneficiary and Telephone Business Meetings, Inc., dba Access Conference Call Service has failed to provide a substitute letter of credit. (b) The letter of credit will be honored by the issuing bank without inquiry as to the accuracy thereof and regardless of whether the Tenant disputes the content of such statement; (c) In the event of a transfer of Landlord's interest in the Building, Landlord shall have the right to transfer the letter of credit to the transferee, and it is agreed that the provisions hereof shall apply to every transfer or assignment of said letter of credit to a new Landlord. In the event of such a transfer, the provider of the letter of credit must be ratified by Landlord by return of a transfer agreement. (d) If, as a result of any such application of all or any part of such letter of credit, the amount secured by the letter of credit shall be less than $100,000.00, Tenant shall forthwith provide Landlord with cash or other immediately available funds, or an additional letter of credit which meets the requirements of this Section, to cover the deficiency, or restore the amount available to be drawn under the letter of credit to the amount required herein upon written notice from Landlord to Tenant. (e) Tenant further covenants that it will not assign or encumber said letter of credit or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. (f) Without limiting the generality of the foregoing, if the letter of credit expires earlier than as provided for herein, or the issuing bank notifies Landlord that it shall not renew the letter of credit, Landlord will accept a renewal thereof or substitute letter of credit (such renewal or substitute letter of credit to be in effect not later than thirty (30) days prior to the expiration thereof), which renewal or substitute letter of credit shall be irrevocable and automatically renewable, and issued by a bank meeting the requirements of this Section, for the entire period provided for in this Section, upon substantially the same terms as the expiring letter of credit or such other terms as may be acceptable to Landlord. However, (i) if the letter of credit is not timely renewed or a substitute letter of credit is not timely received, or (ii) if Tenant fails to 5 maintain the letter of credit in the amount and terms set forth in this Section, then, at least thirty (30) days prior to the expiration of the letter of credit, or immediately upon Tenant's failure to comply with each and every term of this Section, Tenant shall deposit with Landlord cash security in the amounts required by, and to be held subject to the terms of this Section, failing which the Landlord may present such letter of credit to the bank, in accordance with the terms of this Section, and the entire sum secured thereby shall be paid to Landlord as a substitute security deposit, to be held by Landlord in the manner provided for in this Section. If Tenant provides the security deposit in the form of cash or other immediately available funds, Landlord shall deposit such funds into an interest bearing account chosen by Landlord in its reasonable discretion and, provided Tenant is otherwise entitled to repayment of the security deposit hereunder, Tenant shall be entitled to any and all interest accrued thereon. Notwithstanding the foregoing, Tenant acknowledges and agrees that Landlord may commingle the security deposit with other funds in Landlord's possession provided Landlord otherwise complies with the terms hereof. All direct out-of- pocket expenses to set up and maintain such account shall be deducted from any interest earned on the amount of such cash security deposit. If Tenant defaults with respect to any covenant or condition of this Lease, including but not limited to the payment of Monthly Base Rent, additional rent or any other payment due under this Lease, and the obligation of Tenant to maintain the premises and deliver possession thereof back to Landlord at the expiration or earlier termination of the Lease Term in the condition required herein, then Landlord may (without any waiver of Tenant's default being deemed to have occurred) apply all or any part of the security deposit to the payment of any sum in default or any other sum which Landlord may be required or deem necessary to spend or incur by reason of Tenant's default. In such event, Tenant shall, upon demand, deposit with Landlord the amount so applied to replenish the security deposit. If Tenant shall have fully complied with all of the covenants and conditions of this Lease, but not otherwise, the amount of the security deposit (including all interest accrued thereon if any) then held by Landlord shall be repaid to Tenant within thirty (30) days after the expiration or sooner termination of this Lease. In the event of a sale or transfer of Landlord's estate or interest in the Building, Landlord shall have the right to transfer the security deposit to the purchaser or transferee, and Landlord shall be considered released by Tenant from all liability for the return of the security deposit, so long as the transferee acknowledges receipt of the security deposit and Landlord's obligations under this Lease. Notwithstanding anything else herein to the contrary, and provided Tenant is not then in default under the terms of this Lease and no event has occurred which, with notice or the passage of time, or both, would constitute a default under this Lease at the time the provisions of this paragraph are to take effect, then after the end of the second (2nd) Lease Year, Tenant shall only be required to maintain a security deposit of one month's Rent with Landlord. All terms of this Section relating to the security deposit shall be modified to reflect such reduction in the security deposit, mutatis mutandis, but shall ---------------- otherwise remain in full force and effect, and Landlord shall return the Letter of Credit for substitution. 5.

EXPIRATION/TERMINATION OF LEASE. Upon the expiration or sooner ------------------------------- termination of the term hereof, Tenant shall, upon written demand by Landlord, at Tenant's sole expense, with due diligence, remove any Alterations made by Tenant, which at the time of Landlord's approval of such Alterations were designated by Landlord to be removed, and repair any damage to the Premises caused by such removal. In no event shall Tenant be required to remove the Tenant work performed pursuant to Exhibit C and C-1. Notwithstanding the --------- --- foregoing, Tenant shall be required to remove Tenant's telecommunications equipment, computer 29 equipment and cabling, supplemental HVAC equipment and generator at the termination of this Lease and repair any damage to the Premises caused by such removal. Tenant shall remove all of Tenant's moveable property and trade fixtures which can be removed without damage to the Premises at the termination of this Lease, either by expiration of the term or other cause, and shall pay Landlord any damages for injury to the Premises or Building resulting from such removal.

Landlord has expressly agreed in this Lease to ---------------------- perform certain tenant improvement work in the Premises as set forth in Exhibit C. The acceptance of the Premises by Tenant shall be deemed to have occurred five (5) days after substantial completion in accordance with Exhibit C; at such time, Tenant shall be deemed to have accepted the Premises in their then condition except for any "punch list" items (as that term is used in the construction industry) noted by Tenant in writing to Landlord within such five (5) day period pursuant to any inspection of the Premises made by Tenant within such five (5) day period. Landlord shall complete the punch list items within thirty (30) days. If the completion of the punch list is not possible within said thirty (30) day period due to reasons beyond Landlord's control, Landlord shall diligently pursue completion of the punch list. The existence of such punch list items shall not postpone the Lease Commencement Date of this Lease nor the obligation of Tenant to pay Rent or any other charges due under this Lease. 16. TENANT IMPROVEMENTS. The provisions governing the planning, ------------------- construction, scope of work and terms of payment are set forth in EXHIBIT C, --------- which is attached hereto and incorporated herein by this reference. 17.

WAIVER OF SUBROGATION. --------------------- 18.1. TENANT'S WAIVER. Whether due to the negligence of Landlord or --------------- Landlord's agents or employees, or any other cause and notwithstanding any other provision of this Lease, Tenant hereby releases Landlord and Landlord's agents and employees from responsibility for and waives its entire claim of recovery for (i) any loss or damage to the real or personal property of Tenant located in the Building, including the Building itself, arising out of any of the perils which are (or could have been) covered by Tenant's property insurance policy, with extended coverage endorsements, or (ii) loss resulting from business interruption or loss of rental income, at the Premises, arising out of any of the perils which are (or could have been) covered by the business interruption or by the loss of rental income insurance policy held by Tenant. Tenant shall cause its insurance carrier(s) to consent to such waiver of all rights of subrogation against Landlord. 18.2. LANDLORD'S WAIVER. Whether due to the negligence of Tenant or ----------------- Tenant's agents or employees, or any other cause and notwithstanding any other provision of this Lease, Landlord hereby releases Tenant and Tenant's agents and employees from responsibility for and waives its entire claim of recovery for (i) any loss or damage to the real or personal property of Landlord located in the Building, including the Building itself, arising out of any of the perils which are (or could have been) covered by Landlord's property insurance policy, with extended coverage endorsements, or (ii) loss resulting from business interruption or loss of rental income, at the Premises, arising out of any of the perils which are (or could have been) covered by the business interruption or by the loss of rental income insurance policy held by Landlord. Landlord shall cause its insurance carrier(s) to consent to such waiver of all rights of subrogation against Tenant. 19. INDEMNIFICATION. Tenant shall defend, indemnify and hold harmless --------------- Landlord, its agents, employees, officers, directors, partners and shareholders from and against any and all third party liabilities, judgments, demands, causes of action, claims, losses, damages, costs and expenses, including reasonable attorneys' fees and costs, arising out of the negligence or willful misconduct or negligence of, Tenant, its officers, contractors, licensees, agents, servants, employees, guests, invitees, or visitors in or about the Building or Premises or arising from any breach or default under this Lease by Tenant, or arising from any accident, injury, or damage caused by the willful misconduct or negligence of Tenant, occurring in or about the Building or Premises. This indemnification shall survive termination of this Lease. This provision shall not be construed to make Tenant responsible for loss, damage, liability or 31 expense resulting from injuries to third parties caused by the sole negligence or willful misconduct of Landlord, or its officers, contractors, licensees, agents, employees, or invitees. Landlord shall defend, indemnify and hold harmless Tenant, its agents, employees, officers, directors, partners and shareholders from and against any and all third party liabilities, judgments, demands, causes of action, claims, losses, damages, costs and expenses, including reasonable attorneys' fees and costs, arising out of the negligence or willful misconduct of, Landlord, its officers, contractors, licensees, agents, servants, employees, guests, invitees, or visitors in or about the Building or the Premises or arising from any breach or default under this Lease by Landlord, or arising from any accident, injury, or damage caused by willful misconduct or negligence of Landlord, occurring in or about the Building or Premises. This indemnification shall survive termination of this Lease. This provision shall not be construed to make Landlord responsible for loss, damage, liability or expense resulting from injuries to third parties caused by the negligence or willful misconduct of Tenant, or its officers, contractors, licensees, agents, employees, or invitees. 20. ASSIGNMENT AND SUBLETTING. ------------------------- 20.1. LANDLORD'S CONSENT. Tenant shall not assign this Lease, or ------------------ sublease all or any part of the Premises, or permit the use of the Premises by any party other than Tenant, without the prior written consent of Landlord, such consent not to be unreasonably withheld, conditioned or delayed. When Tenant requests Landlord's consent to such assignment or sublease, it shall notify Landlord in writing of (i) the name and address of the proposed assignee or subtenant; (ii) the nature and character of the business of the proposed assignee or subtenant; (iii) financial information including financial statements of the proposed assignee or subtenant; and (iv) a copy of the proposed sublet or assignment agreement. Tenant shall thereafter immediately provide to Landlord any and all other information and documents reasonably requested by Landlord in order to assist Landlord with its consideration of Tenant's request hereunder. Without limitation, it shall not be unreasonable if Landlord denies its consent to a proposed assignment or sublease to an assignee or subtenant (i) which in Landlord's reasonable opinion does not have sufficient financial strength to meet its financial obligations under the assignment or sublease; (ii) which Landlord can demonstrate has a history of committing lease defaults or otherwise failing to meet its contractual obligations either with Landlord, its affiliates, or other landlords; or (iii) to any assignee or sublessee who proposes to use the Premises other than for the uses specifically permitted under Section 5, above. If the proposed sublet or assignment is for more than twenty-five percent (25%) of the rentable area of the Premises, Landlord shall have the option (to be exercised within ten (10) business days from the submission of Tenant's request and receipt of all other information requested hereunder) to cancel this Lease with respect to the portion of the Premises to be subleased or assigned as of the commencement date stated in the proposed sublease or assignment. If Landlord shall not exercise its option within the time set forth above, Landlord's consent to any proposed assignment or sublease shall not be unreasonably withheld. 20.2. APRROVED SUBLEASES AND ASSIGNMENTS. If Landlord approves an ---------------------------------- assignment or sublease as herein provided, Tenant shall pay to Landlord, as Additional Rent due 32 under this Lease, as applicable (i) in the case of a sublease, an overage amount equal to fifty percent (50%) of the difference, if any, between the Rent allocable to that part of the Premises affected by such sublease pursuant to this Lease, and the rent paid by the subtenant to Tenant, less any reasonable and customary expenses incurred by the Tenant in connection with the sublease (including without limitation tenant improvement costs, free rent, brokerage fees, legal costs, moving allowance), and (ii) in the case of an assignment, an overage amount equal to fifty percent (50%) of the premium, if any, received by Tenant for such assignment. Such overage amounts shall be due and payable by Tenant to Landlord within thirty (30) days of Tenant's receipt of payment from the subtenant or assignee. No consent to any assignment or sublease shall constitute a further waiver of the provisions of this Section, and all subsequent assignments or subleases may be made only with the prior written consent of Landlord. An assignee of Tenant, at the option of Landlord, shall become directly liable to Landlord for all obligations of Tenant hereunder and shall assume all such obligations in writing in a form reasonably satisfactory to Landlord, but no sublease or assignment by Tenant shall relieve Tenant of any liability hereunder. Any assignment or sublease without Landlord's consent shall be void, and shall, at the option of the Landlord, constitute a default under this Lease. In the event that Tenant requests that Landlord consider a sublease or assignment hereunder (except with respect to the exercise by Landlord of its option to cancel as set forth in Section 20.1), Tenant shall pay (i) Landlord's reasonable fees, not to exceed Five Hundred and 00/100 Dollars ($500.00) per transaction, incurred in connection with the consideration of such request, and (ii) all reasonable attorneys' fees not to exceed $1,000.00 per transaction and costs incurred by Landlord in connection with the consideration of such request or such sublease or assignment. 21. ADVERTISING. Tenant shall not display any sign, graphics, notice, ----------- picture, or poster, or any advertising matter whatsoever, anywhere in or about the Premises or the Building at places visible from anywhere outside or at the entrance to the Premises without first obtaining Landlord's written consent thereto, such consent to be at Landlord's sole discretion. Tenant shall be responsible to maintain any permitted signs and remove the same at Lease termination. If Tenant shall fail to do so, Landlord may do so at Tenant's expense and Tenant's reimbursement to Landlord for such amount shall be deemed Additional Rent and shall be due within ten (10) days of Landlord's demand therefor. Tenant shall be responsible to Landlord for any damage caused by the installation, use, maintenance or removal of any such signs. Tenant shall have signage rights to install a monument style sign in front of the Building, subject to any applicable governmental laws, ordinances, regulations, and other requirements at Tenant's expense. The size, design and placement of such shall require approval of Landlord, which shall not be unreasonably withheld or delayed, and all applicable zoning, government regulations, ordinances and licenses. 22. LIENS. Tenant shall keep the Premises and the Building free from any ----- liens, including but not limited to liens filed against the Premises by any governmental agency, authority or organization, arising out of any work performed, materials ordered or obligations incurred by or on behalf of Tenant, and Tenant hereby agrees to indemnify and hold Landlord, its agents, employees, independent contractors, officers, directors, partners, and shareholders harmless from any liability, cost or expense for such liens. Tenant shall cause any such lien 33 imposed to be released of record by payment or posting of the proper bond within ten (10) business days after Tenant learns of same. Tenant shall give Landlord written notice of Tenant's intention to perform work on the Premises which might result in any claim of lien, at least ten (10) days prior to the commencement of such work to enable Landlord to post and record a notice of nonresponsibility or other notice deemed proper before commencement of any such work. If Tenant fails to remove any lien within the prescribed ten (10) day period, then Landlord may do so at Tenant's expense and Tenant's reimbursement to Landlord for such amount, including reasonable attorneys' fees and costs, shall be deemed Additional Rent. Tenant shall have no power to do any act or make any contract which may create or be the foundation for any lien, mortgage or other encumbrance upon the reversion or other estate of Landlord, or of any interest of Landlord in the Premises. 23. DEFAULT. ------- 23.1. TENANT'S DEFAULT. A default under this Lease by Tenant shall ---------------- exist if any of the following occurs: 23.1.1. If Tenant fails to pay Rent or any other sum required to be paid hereunder within five (5) business days after written notice from Landlord, except as provided in Section 23.1.5 of this Lease; or 23.1.2. If Tenant fails to perform any term, covenant or condition of this Lease except those requiring the payment of money, and Tenant fails to cure such breach within fifteen (15) days after written notice from Landlord where such breach could reasonably be cured within such fifteen (15) day period, provided, however, that where such failure could not reasonably be cured within the fifteen (15) day period, that Tenant shall not be in default if it commences such performance within the fifteen (15) day period and diligently thereafter prosecutes the same to completion; or 23.1.3. If, to the extent permitted by applicable law, there shall be filed by or against Tenant, in any court pursuant to any statute either of the United States or any state, a petition in bankruptcy or insolvency or for the reorganization of or for the appointment of a receiver, trustee or liquidator for all or any portion of the assets of Tenant, and, within thirty (30) days thereafter, Tenant fails to secure a discharge thereof, or if the Tenant makes an assignment for the benefit of creditors, or if the Tenant admits in writing its or their inability to pay its or their debts; or 23.1.4. If Tenant shall fail to take possession of and/or occupy the Premises within the thirty (30) days following the Lease Commencement Date or if Tenant shall vacate the Premises for a period of fifteen (15) days or more (without giving Landlord notice of such vacancy) at any time following the Lease Commencement Date; or 23.1.5. The chronic delinquency by Tenant in the payment of monthly Rent, or any other periodic payments required to be paid by Tenant under this Lease, shall constitute a default. "Chronic delinquency" shall mean failure by Tenant to pay Rent, or any 34 other periodic payments required to be paid by Tenant under this Lease within three (3) days after written notice thereof for any three (3) months (consecutive or nonconsecutive) during any twelve (12) month period. In the event of a chronic delinquency, at Landlords' option, Landlord shall have the additional right to require that Rent be paid by Tenant quarter-annually, in advance. 23.2. REMEDIES. Upon a default, Landlord shall have the following -------- remedies, in addition to all other rights and remedies provided by law or otherwise provided in this Lease, to which Landlord may resort cumulatively or in the alternative: 23.2.1. Landlord may continue this Lease in full force and effect, and this Lease shall continue in full force and effect as long as Landlord does not terminate this Lease, and Landlord shall have the right to collect Rent and other charges when due. 23.2.2. Landlord may terminate Tenant's right to possession of the Premises at any time by giving written notice to that effect, and relet the Premises or any part thereof. On the giving of the notice, all of Tenant's rights in the Premises, shall terminate. Upon such termination, Tenant shall surrender and vacate the Premises in the condition required by Article 25, and Landlord may re-enter and take possession of the Premises and all the remaining improvements or property and eject Tenant or any of the Tenant's subtenants, assignees or other person or persons claiming any right under or through Tenant or eject some and not others or eject none. This Lease may also be terminated by a judgment specifically providing for termination. Any termination under this Section shall not release Tenant from the payment of any sum then due Landlord or from any claim for damages or Rent or other sum previously accrued or then accruing against Tenant. Upon such termination Tenant shall be liable immediately to Landlord for all costs Landlord incurs in reletting the Premises or any part thereof, including, without limitation, broker's commissions, expenses of cleaning and redecorating the Premises required by the reletting and like costs. Reletting may be for a period shorter or longer than the remaining term of this Lease. No act by Landlord other than giving written notice to Tenant or executing a judgment for possession shall terminate this Lease. Acts of maintenance, efforts to relet the Premises or the appointment of a receiver on Landlord's initiative to protect Landlord's interest under this Lease shall not constitute a termination of Tenant's right to possession. When Tenant is evicted or otherwise vacates the Premises, Landlord has the right, at Tenant's cost and without liability for the loss thereof or damage thereto, to remove all Tenant's personal property, which shall be deemed to have been abandoned by Tenant, and either store same or otherwise dispose of same in Landlord's sole and absolute discretion. Landlord and Tenant hereby acknowledge that in the event of such a termination, actual damages to Landlord may be difficult to ascertain and, accordingly, hereby agree that in such event, the net present value of the Base Rent due from the date of such termination to the Lease Expiration Date, discounted at eight percent (8%) per annum, less the fair rental value of the Premises from the date of such termination or reentry of the Landlord until the Lease Expiration Date, discounted at eight percent (8%) per annum, shall thereupon be immediately due and payable to Landlord to compensate Landlord for Tenant's default and such termination. Tenant waives redemption or relief from forfeiture under any other present or future law, in the 35 event Tenant is evicted or Landlord takes possession of the Premises pursuant to judicial process by reason of any default of Tenant hereunder. 23.2.3. Landlord may, except as may otherwise have been agreed to between the parties pursuant to landlord lien waivers, with or without terminating this Lease, re-enter the Premises by judicial process and remove all persons and property from the Premises; such property shall be deemed to have been abandoned by Tenant and may either be removed and stored in a public warehouse or elsewhere or otherwise disposed of in the Landlord's sole and absolute discretion, all at the cost of the Tenant. The parties hereby agree that Landlord shall not be liable for the loss of such property or any damages thereto. No re-entry or taking possession of the Premises by Landlord pursuant to this Section shall be construed as an election to terminate this Lease unless (i) a written notice of such intention is given to Tenant, or (ii) Tenant is evicted from the Premises. 23.2.4. Landlord's rights pursuant to this Article, including without limitation, Landlord's rights to collect Base Rent, Additional Rent and other charges due under this Lease, shall survive any termination of the Lease, whether such termination is effected pursuant to this Article or otherwise. Notwithstanding anything to the contrary contained herein, Landlord, prior to termination of the Lease or re-entry of the Premises, shall have no obligation or duty to mitigate or attempt to offset any damages which are or may be suffered by Landlord as a result of any default of Tenant under the Lease. From and after termination of the Lease or re-entry of the Premises, Landlord shall use commercially reasonable efforts to mitigate its damages. Any payment by Tenant of a sum of money less than the entire amount due Landlord at the time of such payment shall be applied to the obligations of Tenant then furthest in arrears. No endorsement or statement on any check or accompanying any payment shall be deemed an accord and satisfaction and any payment accepted by Landlord shall be without prejudice to Landlord's right to obtain the balance due or pursue any other remedy available to Landlord both in law and in equity. 23.2.5. Landlord agrees to use good faith, commercially reasonable efforts to relet the Premises and otherwise to mitigate its damages in the event of a default by Tenant. The foregoing notwithstanding (i) Landlord shall not be obligated to show any preference between the Premises and any other vacant space in the Building with regard to any such reletting; (ii) Landlord may make such leasing concession (including but not limited to rental abatement/free rent, tenant improvement allowances, and the like) as Landlord deems appropriate in its sole but reasonable judgment; (iii) Landlord shall have the right to attempt to relet the Premises in whole or in any subdivided part, or in combination with other vacant space in the Building, and to apportion the rentals and concessions thereunder in any fashion Landlord deems appropriate, in its sole but reasonable judgment; and (iv) Landlord's inability to relet the Premises or any part thereof, or to collect rent after any such reletting, despite its good faith efforts, shall not constitute a violation of Landlord's duty to mitigate under this Section 23.2.5. 24. SUBORDINATION. Landlord represents and warrants that as of the date ------------- hereof there are no existing deeds of trust or other liens against the Building. Upon request of Landlord, Tenant will, in writing, subordinate its rights hereunder to any holder of the lien of any mortgage, 36 deed of trust, ground lease or underlying lease hereafter in force against the Premises (the "Landlord's Mortgage"), and to all advances made or hereafter to be made upon the security thereof; provided, however, that Tenant shall grant such subordination only if Tenant simultaneously receives in a form reasonably acceptable to Tenant and Landlord, a non-disturbance agreement from and executed by Landlord's Mortgagee for the benefit of Tenant. Tenant shall execute and return to Landlord any such subordination documents within twenty (20) business days of Landlord's written request. Such non-disturbance agreement shall provide in the event any proceedings are brought for foreclosure, or in the event of the exercise of the power of sale under any mortgage or deed of trust made by the Landlord covering the Premises, that Tenant shall attorn to the purchaser at any such foreclosure, or to the grantee of a deed in lieu of foreclosure, and recognize such purchaser or grantee as the Landlord under this Lease, provided such purchaser or grantee assumes in writing Landlord's obligations under this Lease. 25. SURRENDER OF POSSESSION. Upon expiration of the term of this Lease ----------------------- or as otherwise provided hereunder, Tenant shall promptly and peacefully surrender the Premises to Landlord in as good condition as when received by Tenant from Landlord or as thereafter improved, reasonable use and wear and tear (to the reasonable satisfaction of Landlord) and damage by storm, fire, lightning, earthquake or other casualty excepted. If the Premises are not surrendered in accordance with the terms of this Lease, Tenant shall indemnify Landlord and its agents, employees, independent contractors, officers, directors, partners, and shareholders against any loss or liability including reasonable attorneys' fees and costs, and including liability to succeeding tenants, resulting from delay by Tenant in so surrendering the Premises. This indemnification shall survive termination of this Lease. 26. NON-WAIVER. Waiver by Landlord of any breach of any term, covenant ---------- or condition herein contained shall not be deemed to be a waiver of such term, covenant, or condition(s); or any subsequent breach of the same or any other term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular rental so accepted, regardless of Landlord's knowledge of such preceding breach at the time of acceptance of such Rent. No provision of this Lease shall be deemed to have been waived or modified by Landlord or Tenant unless such waiver or modification shall be in writing and signed by the party against whom such waiver or modification is sought to be enforced. 27. HOLDOVER. If Tenant shall, without the written consent of Landlord, -------- hold over after the expiration of the term of this Lease such tenancy shall be deemed a month-to-month tenancy, which tenancy may be terminated by either party upon thirty (30) days written notice to the other party. During such tenancy, Tenant agrees to pay to Landlord, each month, the greater of the fair market rental value for the Premises or one hundred fifty percent (150%) of the Rent payable by Tenant for the last month of the term of this Lease. 28. CONDEMNATION. If twenty (20) percent or more of the Premises or of ------------ such portions of the Building as may be required for the reasonable use of the Premises, are taken by eminent domain or sale under threat of condemnation by eminent domain, this Lease shall automatically terminate as of the date title vests in the condemning authority, and all Rent and other payments shall be paid to that date. Landlord reserves all rights to damages to the Premises 37 for any partial or entire taking by eminent domain, and Tenant hereby assigns to Landlord any right Tenant may have to such damages or award, and Tenant shall make no claim against Landlord or the condemning authority for damages for termination of the leasehold interest or interference with Tenant's business. Tenant shall have the right to claim and recover from the condemning authority compensation for any loss which Tenant may incur for Tenant's moving expenses, business interruption or taking of Tenant's personal property (not including Tenant's leasehold interest). 29. NOTICES. All notices and demands which may be required or permitted ------- to be given to either party hereunder shall be in writing, and shall be sent by overnight courier or United States mail, postage prepaid, certified or registered with return receipt requested, to the addresses set forth below, or to such other person or place as each party may from time to time designate in a notice to the other.

LANDLORD'S LIABILITY. -------------------- 33.1. Anything in this Lease to the contrary notwithstanding, covenants, undertakings and agreements herein made on the part of Landlord are made and intended not for the purpose of binding Landlord personally or the assets of Landlord but are made and intended to bind only the Landlord's interest in the Premises and Building (including the rent account, insurance proceeds and any condemnation award) , as the same may, from time to time, be encumbered and no personal liability shall at any time be asserted or enforceable against Landlord or its stockholders, officers or partners or their respective heirs, legal representatives, successors and assigns on account of the Lease or on account of any covenant, undertaking or agreement of Landlord in this Lease. 33.2.
