Tenant hereby waives any claim for damages for any inconvenience to or interference with Tenant's business or any loss of occupancy or quiet enjoyment of the Premises by reason of the foregoing. Landlord and/or any owner of all or any portion of the Project shall have the right to convey its ownership of all or any part of the Project to one or more third parties, and thereafter the third party shall have the right to remove such conveyed portion from the definition of "Project" set forth in this Lease.

Actual Operating Expenses for each calendar year shall be adjusted to equal Landlord's reasonable estimate of Operating Expenses had the total Rentable Area of the Project been occupied. If Landlord is not furnishing any particular work or service (the cost of which, if performed by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional Operating Expenses which would reasonably have been incurred during such period by Landlord if Landlord had at its own expense furnished such work or service. (e) The term "Tax Expenses" shall mean all federal, state, county, municipal or local governmental taxes, fees, charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary, including, without limitation, real estate taxes, general and special taxes and/or assessments (including, without limitation, any assessment, tax, fee, levy or charge by any school, agricultural, lighting, drainage, transportation, community facilities, improvement or other district), transit taxes, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances, furniture and other personal property used in connection with the Project, which shall be paid during any calendar year (without regard to any different fiscal year used by such governmental authority) because of or in connection with the ownership, leasing and/or operation of the Project. Tax Expenses shall include any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax, fee, levy or charge previously included within the definition of Tax Expenses, and all consultants' and attorneys' fees and expenses incurred for the purpose of maintaining an equitable assessed valuation of the Building and/or attempting to protest, reduce or minimize Tax Expenses. (f) The term "Building Operating Expenses" shall mean the portion of Operating Expenses allocated to the Building pursuant hereto. The term "Building Tax Expenses" shall mean the portion of Tax Expenses allocated to the Building pursuant hereto. The parties acknowledge that the Building is a part of a multi-building project and that the costs and expenses incurred in connection with the Project should be shared between the tenants of the Building and the tenants of the other buildings of the Project. Accordingly, Operating Expenses and Tax Expenses are determined annually for the Project as a whole, and a portion of the Operating Expenses and Tax Expenses, respectively, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the tenants of the Building (as opposed to the tenants of any other buildings of the Project) and such portion shall be the Building Operating Expenses and Building Tax Expenses, respectively, for purposes of this Lease. Such portion of Operating Expenses and Tax Expenses allocated to the tenants of the Building shall include all Operating Expenses and Tax Expenses, respectively, attributable solely to the Building, and an equitable portion of the Operating Expenses and Tax Expenses, respectively, attributable to the Project as a whole. In addition, Landlord shall have the right, from time to time, to equitably allocate some or all of the Operating Expenses and/or Tax Expenses for the Project among different portions or occupants of the Project, in Landlord's discretion. (g) The term "Rentable Area" shall mean the area or areas of space within any building in the Project determined as follows: (i) the amount of Rentable Area on a single tenancy floor is determined by measuring from the inside surface of the outer glass and extensions of the plane thereof in nonglass areas and shall include all areas within the outside walls, excluding vertical penetrations such as building stairs, elevators shafts, flues, vents, stacks, pipe shafts and vertical ducts, provided, however, that vertical penetrations which are for the specific use of the tenant, such as special stairs or elevators, shall be included within Rentable Area; (ii) the amount 3 <PAGE> 7 of Rentable Area for a partial floor shall include all space within the demising walls (measured from the mid-point of demising walls, and in the case of exterior walls, measured as defined in clause (i) above), plus the tenant's share of any Common Areas on such floor (such share being equal to the percentage which the amount of Rentable Area within the Premises bears to the total amount of Rentable Area on the floor); and (iii) the amount of Rentable Area for either a single tenancy floor or a partial floor shall include Tenant's Percentage of Common Areas devoted to or serving more than one floor of the applicable building or such building as a whole. No deductions shall be made in calculating the amount of Rentable Area for columns or projections necessary to the Building. Notwithstanding the foregoing or anything elsewhere contained in this Lease, the parties hereby agree that for all purposes of this Lease, the Premises shall be deemed to contain the amount of Rentable Area, and that Tenant's Base Rent, Percentage Share, Security Deposit, and all other matters determined by the amount of Rentable Area contained in the Premises shall be the amount set forth in the Basic Lease Information, notwithstanding any deviation therefrom. Landlord shall have the right at any time and from time to time to have its architect or space planner remeasure and certify in writing the Rentable Area of the Premises, which determination and certification shall be conclusive, and thereupon Tenant's Percentage Share, Base Rent, Security Deposit, and any other matters in this Lease which are determined based upon the Rentable Area contained in the Premises shall be adjusted accordingly, if required. (h) The term "Usable Area" shall mean all floor area in a tenant space, measured from the inside surface of the outer glass and extensions of the plane thereof in non-glass areas and shall include all areas within the outside walls, excluding vertical penetrations such as building stairs, elevators shafts, flues, vents stacks, pipe shafts and vertical ducts, provided, however, that vertical penetrations which are for the specific use of the tenant, such as special stairs or elevators, shall be included within Usable Area. In calculating Usable Area, deductions shall not be made for columns or projections necessary to the Building. (i) The term "Common Areas" shall mean those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project, which may include, without limitation, public entrances, lobbies and rest rooms, fitness centers, restaurants or cafeterias, elevators, stairways and access ways, loading docks, ramps, drives and platforms and any passageways and service ways thereto, common pipes, conduits, wires and appurtenant equipment serving the Project or any portion thereof, loading and unloading areas, trash areas, parking areas, roadways, sidewalks, walkways, parkways, driveways and landscaped areas. (j) "The term "Tenant's Percentage Share" shall mean the product obtained by multiplying (i) 100 by (ii) the quotient obtained by dividing the Rentable Area of the Premises by the total Rentable Area of the Building. Tenant's Percentage Share shall initially be as specified in the Basic Lease Information and shall be subject to adjustment in the event of a change in the Rentable Area of the Premises and/or the Building (with Tenant's Percentage Share as to the calendar year in which any such change occurs being determined on a pro rata basis based on the number of days during such calendar year at each such percentage share). Notwithstanding the foregoing or anything contained in this Lease to the contrary, Tenant's Percentage Share of Operating Expenses attributable to a restaurant, fitness center and/or similar facility(ies) located at the Project shall be (i) separately determined with respect to each such facility and (ii) obtained by multiplying (i) 100 by (ii) the quotient obtained by dividing the Rentable Area of the Premises by the total Rentable Area occupied by tenants of the Project who also pay their respective share of such Operating Expenses (ie space occupied by tenants who do not participate in such costs shall be excluded). Landlord shall use reasonable efforts to negotiate all future leases (as opposed to expansions, renewals, or leases entered into with existing tenants (or their affiliates)) for space at the Project, as the same exists as of the Commencement Date, such that the tenants thereunder will be obligated to pay their respective share of such Operating Expenses. (k) The term "Laws" shall mean, collectively, any applicable federal, state, local and/or municipal laws, statutes, ordinances, codes, rules, regulations and/or other governmental requirements. 4 <PAGE> 8 2. Term; Condition of Premises. (a) The "Term" of this Lease shall commence on the "Commencement Date" (as defined in Exhibit "C" attached hereto) and, unless sooner terminated as hereinafter provided, shall be for the period specified in the Basic Lease Information. If without fault of Tenant the Commencement Date of this Lease has not occurred by the date which is ninety (90) days following the Estimated Commencement Date set forth above (subject to Force Majeure), this Lease shall terminate without further action by the parties, and neither party shall have any further liability or obligation hereunder. Except to the extent specifically otherwise provided in this Lease, Landlord shall deliver the Premises to Tenant on the Commencement Date in an "as is" condition with no alterations or improvements being made by Landlord. Following the Commencement Date, Landlord may deliver to Tenant a notice confirming the actual Commencement Date and the date of the expiration of the Term specified in the Basic Lease Information, which notice shall be executed by Tenant and returned to Landlord within five (5) days following Tenant's receipt thereof. Tenant is aware that a portion of the Premises located on the second (2nd) floor of the Building is currently leased to another tenant of Landlord (the "Existing Tenant"). Tenant acknowledges and agrees that Landlord's obligation to deliver possession of the Premises to Tenant, and to otherwise complete the transaction contemplated under this Lease, shall be subject to Landlord's ability to cause the Existing Tenant of the Premises to surrender the same to Landlord, on such terms and conditions as are acceptable to Landlord in its sole and absolute discretion. Landlord shall have no liability to Tenant if Landlord is not able to effectuate the Existing Tenant's surrender of such space on terms acceptable to it. However, notwithstanding the ninety (90) day period referenced in the preceding paragraph, if the Existing Tenant does not surrender such space to Landlord on or before December 7, 1999, then Tenant may cancel this Lease by delivering written of cancellation to Landlord by 5:00 p.m. on December 10, 1999, in which case neither party shall have any obligation to the other under this Lease. Tenant's failure to deliver written notice of cancellation notice by such time shall be deemed an election not to cancel this Lease. (b) Provided Tenant is not in default under this Lease (which shall include any matter which would constitute a default either with the passage of time or the giving of notice) at any time prior to the time the "Extension Notice" (as hereinafter defined) is received by Landlord or thereafter until the commencement of the "Option Term" (as hereinafter defined) (subject to applicable cure periods, if any), Tenant shall have the option to extend the Term of this Lease for one (1) additional term (an "Option Term") of five (5) years following the expiration of the initial Term, exercisable by delivering written notice (the "Extension Notice") to Landlord of Tenant's desire to so extend the Term by the Option Term, no later than nine (9) months, and no earlier than twelve (12) months (except as permitted under Section 40 below), prior to the expiration of the initial Term. Tenant's occupancy of the Premises during the Option Term shall be subject to all of the terms and conditions of this Lease, except that (i) the Base Rent payable by Tenant as of the commencement of the Option Term shall be ninety-five percent (95%) of Landlord's then current published rental rate for similar space in the Project, as determined by Landlord, but in no event shall such Base Rent be less than the amount payable by Tenant on the last day of the initial Term and (ii) Landlord shall have no obligation to improve the Premises for the benefit of Tenant. Wherever in this Lease the phrase the "initial Term" appears, the provision to which such phrase pertains shall apply only to the initial Term and not to the Option Term. The Base Rent payable by Tenant during the Option Term shall be subject to increase at the times and in the manner described in Section 3(g) below. 3. Base Rent. (a) Tenant shall pay to Landlord from and after the Commencement Date (other than with respect to the Must Take Space as provided in Section 41 below) during the Term of this Lease as "Base Rent" for the Premises, the monthly amount specified in the Basic Lease Information. (b) Base Rent shall be paid to Landlord, in advance, on or before the first day of each calendar month during the Term, except that Base Rent for the initial full month during the Term for which Base Rent is due shall be 5 <PAGE> 9 paid upon the execution of this Lease (provided that such payment shall be subject to adjustment payment or reimbursement, as applicable, in the event the actual Rentable Area of the Premises is determined to be other than as set forth in the Basic Lease Information). In the event the Term commences on a day other than the first day of a calendar month or ends on a day other than the last day of a calendar month, the monthly Base Rent for the first and last fractional months of the Term shall be appropriately prorated. (c) All sums of money due to Landlord under this Lease not specifically characterized as rental shall constitute additional rent, and if any such sum is not paid when due it shall nonetheless be collectible as additional rent with the next installment of Base Rent thereafter falling due, but nothing contained herein shall be deemed to suspend or delay the payment of any sum of money at the time it becomes due and payable hereunder, or to limit any other remedy of Landlord (d) Tenant hereby acknowledges that late payment by Tenant to Landlord of rent and other sums due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges, and late charges which may be imposed on Landlord by the terms of any trust deed covering the Premises. Accordingly, if any installment of rent or any other sums due from Tenant shall not be received by Landlord within five (5) days of the date due, Tenant shall pay to Landlord a late charge equal to the greater of (i) 6% of such overdue amount or (ii) $100.00. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. Acceptance of such late charge by Landlord shall in no event constitute a waiver of Tenant's default with respect to such overdue amount, nor prevent Landlord from exercising any of the other rights and remedies granted hereunder. If a late charge becomes payable for three (3) payments of any element of rent within any twelve (12) month period, all subsequent payments of rent shall immediately and automatically become payable by Tenant quarterly, in advance, instead of monthly. Tenant acknowledges that its payment of Base Rent and additional rent is a condition to Landlord's obligation to perform any of its covenants under this Lease. (e) Any amount due to Landlord pursuant to this Lease, if not paid when due, shall bear interest from the date due until paid at a rate (the "Interest Rate") equal to the lesser of (i) 2% over the "prime" or "reference" rate then most recently published by Bank of America N.T. & S.A. (or a substitute prime rate of a comparable lending institution reasonably selected by Landlord if Bank of America N.T. & S.A. no longer publishes a "prime" or "reference" rate), or (ii) the maximum rate permitted by applicable Laws. Payment of interest shall not excuse or cure any default hereunder by Tenant. (f) All payments of Base Rent, Escalation Rent and other monetary obligations due from Tenant to Landlord pursuant to this Lease shall be paid to Landlord, without deduction, abatement, counterclaim or offset, in lawful money of the United States of America at Landlord's address for notices hereunder, or to such other person or at such other place as Landlord may from time to time designate by notice to Tenant. (g) On each twelve (12) month anniversary of the Commencement Date during the Term, including, without limitation, any extension(s) and/or renewal(s) thereof (each such day hereinafter referred to as an "Adjustment Date"), the Base Rent payable by Tenant on the date immediately preceding the applicable Adjustment Date shall be increased by three percent (3%) and such increased amount shall constitute the Base Rent until the next Adjustment Date. Landlord's failure to request payment of an estimated or actual rent adjustment shall not constitute a waiver of the right to any adjustment provided for in this Lease. 4. Escalation Rent. (a) Tenant shall pay to Landlord as "Escalation Rent" for the Premises, during each full or partial calendar year during the Term, (i) Tenant's Percentage Share of all Building Operating Expenses for such year, plus (ii) Tenant's Percentage Share of all Building Tax Expenses for such year. Escalation Rent shall be paid monthly on an estimated basis, with subsequent annual reconciliation, in accordance with the procedures set forth 6 <PAGE> 10 in this Section 4. Tenant acknowledges that this Lease is what is commonly referred to as a "triple net" lease, and that Tenant will be responsible for its Percentage Share of all Building Operating Expenses and Building Tax Expenses, without reference to any Base Year concept. (b) During December each calendar year, or as soon thereafter as practicable, Landlord shall give Tenant notice of its estimate of any Escalation Rent due for the ensuing calendar year. On or before the first day of each month during the ensuing calendar year, Tenant shall pay to Landlord 1/12th of such estimated Escalation Rent, provided that if such notice is not given in December, Tenant shall continue to pay on the basis of the prior year's estimate until such revised estimate is delivered, from and after which time (commencing with the first day of the next calendar month after such notice is given; or if such first day is less than fifteen (15) days after the date of Landlord's notice, then on the first day of the second calendar month after such notice is given) Tenant shall pay such amount as is necessary to bring Tenant current with respect to such revised estimate for such calendar year, as if such revised estimate had been delivered in December, and thereafter monthly payments shall be based on such revised estimate, unless and until further revised in accordance herewith. If at any time or times it appears to Landlord that the Escalation Rent for the current calendar year will vary from its estimate, Landlord may, by notice to Tenant, revise its estimate for such year, and subsequent payments by Tenant for such year shall be based upon such revised estimate. (c) Within 90 days after the close of each calendar year or as soon after such 90-day period as practicable, Landlord shall deliver to Tenant a statement of the actual Escalation Rent for such calendar year, accompanied by a statement showing the Building Operating Expenses and Building Tax Expenses on the basis of which the actual Escalation Rent was determined. Except as expressly provided to the contrary in Section 4(c)(i) below, such statement shall be final and binding upon Landlord and Tenant as to the amount of the Building Operating Expenses and Building Tax Expenses. If Landlord's statement discloses that Tenant owes an amount that is less than the estimated payments for such calendar year previously made by Tenant, Landlord shall credit such excess first against any sums then owed by Tenant to Landlord and then against the next payments of rental due hereunder. If Landlord's statement discloses that Tenant owes an amount that is more than the estimated payments for such calendar year previously made by Tenant, Tenant shall pay the deficiency to Landlord within thirty (30) days after delivery of the statement. The failure of Landlord to timely furnish the statement for any calendar year shall not prejudice Landlord from enforcing its rights hereunder. (i) Provided that Tenant is not in default in its obligations under this Lease (including any matter which would constitute a default with either the passage of time or the giving of notice)(subject to applicable cure periods, if any), Tenant may, within sixty (60) days following the delivery by Landlord to Tenant of the statement of Escalation Rent described above, request in writing an audit of the Building Operating Expenses and Building Tax Expenses which form the basis upon which Landlord determines the actual Escalation Rent. Tenant shall specify in such written notice the portions of the Landlord's statement disputed by Tenant, and, as a condition to Tenant's audit rights hereunder, such notice must be accompanied by Tenant's payment in full to Landlord of all amounts due from Tenant to Landlord as specified in the Landlord's statement. Tenant shall have no right to withhold, deduct, or offset any monetary obligation of Tenant to Landlord under the Lease (including, without limitation, Tenant's obligation to make all rental payments owing under this Lease, including, without limitation, all Escalation Rent) pending the completion of and regardless of the results of any audit of records under this Section. The right of Tenant under this Section 4(c)(i) may only be exercised once for each Landlord's statement of Escalation Rent, and if Tenant fails to meet any of the above conditions as a prerequisite to the exercise of such right, the right of Tenant under this Section as to a particular Landlord's statement of Escalation Rent shall be deemed waived. Tenant shall cause any audit requested by it under this Section 4(c)(i) to be performed by an independent firm of certified public accountants. Tenant must complete its audit within ninety (90) days of the date of Tenant's audit request. 7 <PAGE> 11 (ii) Tenant acknowledges that Landlord maintains its records for Building Operating Expenses and Building Tax Expenses at its offices (as the same may be located from time to time) and Tenant therefore agrees that any review of records under Section 4(c)(i) above shall occur at such location and, except as provided in Section 4(c)(vii) below, be at the sole expense of Tenant. If Tenant discovers a discrepancy, then, at Landlord's option, a further review shall be conducted in accordance with the provisions of Section 4(c)(iv) below. (iii) Tenant acknowledges and agrees that any records reviewed under Section 4(c)(i) constitute confidential information of Landlord, which shall not be disclosed to anyone other than the accountants performing the review and the principals of Tenant who receive the results of the review; except in the event of any litigation concerning the same, in which case, Tenant will use its best efforts to keep such information confidential. Except as set forth in this Section 4(c)(iii), Tenant's disclosure of such information to any other person shall constitute a material breach of this Lease. (iv) Any errors disclosed by the review of records under Section 4(c)(i) shall be promptly corrected, provided that Landlord shall have the right to cause another review of the records to be made by an independent firm of certified public accountants selected by Landlord. In the event of a disagreement between Landlord's accounting firm and Tenant's accounting firm, a third review by an independent firm of certified public accountants of national standing jointly chosen by Landlord and Tenant shall be made and the determination of such accounting firm shall be deemed to be correct. The costs of the third accounting firm shall be shared equally between Landlord and Tenant, and Tenant's failure to pay its share of such costs shall be a default under this Lease. (v) In the event that the results of the review of records (taking into account, if applicable, the results of any additional review caused by Landlord), reveal that Tenant has overpaid obligations for a preceding period, the amount of such overpayment shall be credited by Landlord against subsequent installment obligations to pay its share of estimated Building Operating Expenses and Building Tax Expenses; provided, however, that if the amount of credit exceeds the rent due for the balance of the term of this Lease, Landlord shall pay any excess to Tenant within thirty (30) days after the expiration of the term of this Lease; provided, further, that Landlord shall have the right to retain any such excess and apply the same against any sums which Landlord would otherwise be entitled to receive under this Lease as a result of any default by Tenant. In the event that such results show that Tenant has underpaid its obligations for a preceding period, the amount of such underpayment shall be paid by Tenant to Landlord with the next succeeding installment obligation of estimated Building Operating Expenses and Building Tax Expenses. (vi) If the results of the audit procedures described in this Section 4 disclose that Landlord has overstated the aggregate amount of Building Operating Expenses and Building Tax Expenses by more than eight percent (8%) and the parties do not reach agreement on some amount prior to retaining the third accounting firm described in Section 4(c)(iv) above, Landlord shall pay Tenant's reasonable and hourly audit costs (as shown on invoices or other reasonable evidence submitted to Landlord) not to exceed five hundred dollars ($500). Similarly, if the results of the audit procedures described in this Section 4 above disclose that Landlord has understated the aggregate amount of Building Operating Expenses and Building Tax Expenses by more than eight percent (8%) and the parties do not reach agreement on some amount prior to retaining the third accounting firm described in Section 4(c)(iv) above, Tenant shall pay Landlord's reasonable and hourly audit costs (as shown on invoices or other reasonable evidence submitted to Landlord) not to exceed five hundred dollars ($500.00). (vii) In the event that Tenant becomes in default of its obligations under this Lease at any time during the pendency of a review of records under this Section (subject to applicable cure periods, if any), said right to review shall immediately cease and the matters originally set forth in the Landlord's Statement shall be deemed to be correct. 8 <PAGE> 12 (d) The amount of Escalation Rent for any partial calendar year in the Term shall be appropriately prorated. The termination of this Lease shall not affect the obligations of Landlord and Tenant pursuant to Section 4(c) above to be performed after such termination. 5. Use. (a) The Premises shall be used for general office purposes and, solely in connection with Tenant's computer business, laboratory assembly and testing, and for no other use or purpose. Tenant shall not do or permit to be done in or about the Premises, nor bring to keep or permit to be brought or kept therein, anything which is prohibited by or will in any way conflict with any Laws now in force or which may hereafter be enacted or promulgated, or which is prohibited by the standard form of fire insurance policy, or will in any way increase the existing rate of or affect any fire or other insurance upon the Building or any of its contents, or cause a cancellation of any insurance policy covering the Project, the Building or any of its contents. Tenant shall not do or permit anything to be done in or about the Premises which will in any way obstruct or interfere with the rights of other tenants of the Building, or injure or annoy them, or use or allow the Premises to be used for any improper, immoral, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance or waste in, on or about the Premises. (b) Except general office supplies typically used in an office area in the ordinary course of business, such as copier toner, liquid paper, glue, ink, and cleaning solvents, for use in the manner for which they were designed, in such amounts as may be normal for the office business operations conducted by Tenant in the Premises, neither Tenant nor its agents, employees, contractors, licensees, subtenants, assignees, concessionaires or invitees shall use, handle, store or dispose of any "Hazardous Materials" (as hereinafter defined) in, on, under or about the Premises, the Building or the Project. In the event of a breach of the foregoing covenant, in addition to and without limitation upon any other rights or remedies of Landlord under this Lease, Tenant or, at Landlord's election, Landlord, in each case at Tenant's sole cost, shall promptly take all actions as are necessary to return the Premises, Building and/or Project to the condition existing prior to the introduction of any such Hazardous Materials, provided Landlord's approval of such actions shall first be obtained and Tenant shall fully cooperate in connection with any such clean-up, restoration or other work. Furthermore, Tenant shall immediately notify Landlord of any inquiry, test, investigation or enforcement proceeding by or against Tenant or the Premises concerning the presence of any Hazardous Materials. Tenant acknowledges that Landlord, at Landlord's election, shall have the sole right, at Tenant's expense, to negotiate, defend, approve and appeal any action taken or order issued by any governmental authority with regard to any Hazardous Materials contamination which Tenant is obligated hereunder to remediate. As used herein, "Hazardous Materials" shall mean asbestos, and petroleum fuel, and any hazardous or toxic substance, material or waste (or subparts thereof) which is or become regulated by any local governmental authority, the State of California or the United States Government, including, but not limited to, any material or substance defined as a "hazardous waste," "extremely hazardous waste," "restricted hazardous waste," "hazardous substance," "hazardous material" or "toxic pollutant" under the California Health and Safety Code and/or under the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. 9601, et seq. Landlord represents and warrants to Tenant that Landlord has no actual knowledge (without any obligation of inquiry or investigation) that Hazardous Materials exist on or under land on which the Project is located. 6. Services. (a) Landlord shall maintain the Common Areas of the Project, the exterior facing windows in the Building, the mechanical, plumbing and electrical equipment serving the Building, and the Building structure itself in reasonably good order and condition except for damage occasioned by the act of Tenant and/or any of Tenant's employees, agents, representatives, contractors and/or invitees, which damage shall be repaired by Landlord at Tenant's expense. 9 <PAGE> 13 (b) Landlord shall cause to be furnished (1) elevator service, (2) lighting replacement (for building standard lights located in any Common Areas), (3) Common Area rest room supplies, and (4) security measures and/or services and janitor service during the times and in the manner that such services are customarily furnished in comparable office buildings in the area; provided that janitor service shall be provided five (5) days a week. The Premises shall be separately metered for electricity use (including, without limitation, electricity to provide HVAC service to the Premises) and other utilities at Tenant's cost, and Tenant shall pay the fees charged for such utility costs, as additional rent, either (1) prior to delinquency directly to the utility provider, or (2) if Landlord is billed for such usage by the utility provider, Tenant shall make such payments to Landlord within ten (10) days following Landlord's billing of Tenant therefor. Tenant shall also be responsible for the costs of any and all services, including, without limitation, maintenance, repair, or replacement, provided to the Premises. Landlord may establish reasonable measures to conserve energy, including, but not limited to, automatic switching of lights after hours and more efficient forms of lighting, so long as such measures do not unreasonably interfere with Tenant's use of the Premises. Landlord shall not be in default hereunder or be liable for any damages directly or indirectly resulting from, nor shall the rental herein reserved be abated by reason of (i) the installation, use or interruption of use of any equipment in connection with the furnishing of any of the foregoing services, (ii) failure to furnish or delay in furnishing any such services when such failure or delay is caused by accident or any condition beyond the reasonable control of Landlord or by the making of necessary repairs or improvements to the Premises, Building or Project, or (iii) the limitation, curtailment, rationing or restrictions on use of water, electricity, gas or any other form of energy or utility serving the Premises, Building or Project. Landlord shall use reasonable efforts diligently to remedy any interruption in the furnishing of such services. Notwithstanding the foregoing, if failure to provide any service or utility required of Landlord under this Lease is due to the gross negligence or wilful misconduct of Landlord and such failure shall continue for five (5) consecutive business days or more, and provided such failure to provide the required service precludes Tenant from occupying all or any portion of the Premises, then Base Rent shall be abated hereunder at the rate of one day's Base Rent for each day of such interruption; provided, that in the event Tenant occupies some, but not all of the Premises during such interruption in services, the abatement afforded Tenant shall be a proportion of daily Base Rent equal to a fraction, the denominator of which is the Rentable Area of the Premises and the numerator of which is the Rentable Area of the portion of the Premises that is not occupied by Tenant during such interruption. (c) If heat-generating equipment or lighting other than building standard lights are installed or used in the Premises and such equipment or lighting affects the temperature otherwise maintained by the air conditioning system, or if equipment is installed in the Premises which requires separate temperature-controlled room, at Landlord's election after notice to Tenant, Landlord shall install supplementary air conditioning facilities in the Premises or otherwise modify the ventilating and air conditioning system serving the Premises, and the capital and maintenance costs of such facilities and modifications shall be borne by Tenant. (d) Tenant shall reimburse Landlord, upon billing thereof, for the cost of (i) all electricity, power and cooling energy for heat or air conditioning provided to the Premises, at the then prevailing rate therefor established by Landlord. Tenant shall also pay the cost of any transformers, additional risers, panel boards and other facilities if and to the extent required to furnish power for supplementary air conditioning facilities in or serving the Premises or power for lighting and office equipment. (e) In the event that Landlord, at Tenant's request, provides services to Tenant that are not otherwise provided for in this Lease, Tenant shall pay Landlord's reasonable charges for such services upon billing thereof. (f) Subject to Force Majeure, Landlord's rules and regulations, other matters relating to Building and Project security, and related issues as reasonably adopted by Landlord from time to time, Tenant shall have access to the Premises (and the Project as necessary to access the Premises) twenty-four (24) hours a day, three hundred sixty-five (365) days a year. Landlord shall 10 <PAGE> 14 provide Tenant with use of the key card access system, if any, existing at the Building as of the Commencement Date, and Landlord shall maintain such key card system, if any, in good operating condition and repair; provided, however, that Landlord may in its sole and absolute discretion remove any such key card access system from the Building. (g) Tenant acknowledges that this Lease is what is commonly known as a "triple net" lease, and that Tenant shall be responsible for the payment of any and all costs and expenses of any and all services provided to the Premises by Landlord or others, regardless of whether or not this Lease states that such costs shall be paid by Tenant. 7. Impositions Payable by Tenant. In addition to the monthly rental and other charges to be paid by Tenant hereunder, Tenant shall pay or reimburse Landlord for any and all of the following items (hereinafter collectively referred to as "Impositions"), whether or not now customary or in the contemplation of the parties hereto: taxes (other than local, state and federal personal or corporate income taxes measured by the net income of Landlord from all sources), assessments (including, without limitation, all assessments for public improvements, services or benefits, irrespective of when commenced or completed), excises, levies, business taxes, license, permit, inspection and other authorization fees, transit development fees, assessments or charges for housing funds, service payments in lieu of taxes and any other fees or charges of any kind, which are levied, assessed, confirmed or imposed by any public authority, but only to the extent the Impositions are (a) upon, measured by or reasonably attributable to the cost or value of Tenant's equipment, furniture, fixtures and other personal property located in the Premises, or the cost or value of any leasehold improvements made in or to the Premises by or for Tenant, regardless of whether title to such improvements shall be in Tenant or Landlord (b) upon or measured by the monthly rental or other charges payable hereunder, including, without limitation, any gross receipts tax levied with respect to the receipt of such rental (c) upon, with respect to or by reason of the development, possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion thereof or (d) upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. In the event that it shall not be lawful for Tenant to reimburse Landlord for the Impositions but it is lawful to increase the monthly rental to take into account Landlord's payment of the Impositions, the monthly rental payable to Landlord shall be revised to net Landlord the same net return without reimbursement of the Impositions as would have been received by Landlord with reimbursement of the Impositions. 8. Alterations. (a) Tenant shall not make or suffer to be made any alterations, additions or improvements to the Premises (collectively, "Alterations"), without Landlord's prior consent, which consent shall not be unreasonably withheld (except that such consent may be granted or withheld in Landlord's sole and absolute discretion as to any proposed Alterations which would affect the Building exterior, structural components or utility or life-safety systems). For purposes hereof, "Alterations" shall include, without limitation, air lines, power panels, electrical distribution, security, fire protection systems, communications (including, without limitation, telephone lines), lighting fixtures, heating, ventilating and air conditioning equipment, plumbing, and fencing, in, on or about the Premises. Notwithstanding the foregoing, Tenant may make cosmetic alterations to the Premises, the cost of which do not exceed ten thousand dollars ($10,000.00), without Landlord's consent as long as (i) Tenant provides Landlord with at least thirty (30) days' notice thereof and (ii) such changes are not visible from outside the Building and do not affect in any way the Building exterior, structural components or utility or life-safety systems of the Building. All Alterations shall be made by Landlord for Tenant's account in accordance with the procedures set forth in this Section. All Alterations shall immediately become Landlord's property and, at the end of the Term hereof, shall remain on the Premises without compensation to Tenant unless Landlord elects by notice to Tenant to require the removal of any such Alterations, in which event Tenant shall be responsible for the cost of Landlord's removal of such Alterations and restoration of the Premises to its condition prior to the installation of such Alterations. Notwithstanding the foregoing, Tenant may 11 <PAGE> 15 include the following notice (in bold, all capitalized twelve point type) in its request for consent to an Alteration: "LANDLORD'S RESPONSE TO THIS REQUEST FOR CONSENT MUST INCLUDE LANDLORD'S ELECTION TO REQUIRE TENANT TO REMOVE THE SUBJECT ALTERATION AT THE EXPIRATION OF THE LEASE TERM OR LANDLORD WILL BE DEEMED TO HAVE WAIVED ITS RIGHT TO REQUIRE TENANT TO REMOVE SAID ALTERATION". Tenant shall not be required to remove the Alteration at the expiration of the Term if the foregoing language was included in Tenant's request for consent and Landlord failed to make such election in its response thereto; provided, however, that Landlord's waiver, if any, shall automatically (and retroactively) be void if this Lease terminates as a result of Tenant's default. (b) Plans and specifications for the Alterations shall be prepared at Tenant's expense by either its architect or Landlord's architect if Tenant so elects, and by engineers approved by Landlord where mechanical or electrical engineering services are required by the nature of the Alterations. Tenant shall cause any architect retained by it to follow the standard construction administration procedures and to utilize the standard specifications and details promulgated by Landlord for the Building. The plans and specifications shall be subject to approval by Landlord and Tenant, which approval shall not be unreasonably withheld by either party, and following such approval Landlord shall obtain quotations of the cost of the Alterations as reflected by the approved plans and specifications from one or more general contractors approved by Landlord for construction in the Building. Landlord shall submit the quotations to Tenant, shall accept the quotations approved by Tenant, and shall proceed to enter into a contract for the construction or installation of the Alterations with the contractor whose quotation was approved by Tenant. Landlord itself does not warrant the cost of the Alterations or the timeliness of performance or the quality of the contractor's work, but Landlord shall use reasonable efforts to secure performance of the construction contract for Tenant's benefit. (c) In the event Landlord or the contractor is instructed by Tenant to proceed with any changes to the alterations without a prior determination of any increased costs resulting from such changes and without approval of such increases by Tenant, or in the event Tenant is responsible for increased costs attributable to a delay or acceleration in the time for construction, the amount of any increased costs shall be as reasonably determined by Landlord upon completion of the Alterations, subject only to Landlord's reasonable efforts in causing the contractor to furnish Tenant appropriate back-up information concerning increased costs, if any. (d) The cost of the Alterations to be paid by Tenant shall include a reasonable charge for the administration by Landlord or its agent of the construction or installation of the Alterations, which Landlord and Tenant agree shall be ten percent (10%) of the total costs of design and construction. (e) Tenant shall pay to Landlord all amounts payable by Tenant pursuant to this Section within fifteen (15) days after billing by Landlord. Bills may be rendered in advance of or during the progress of the Alterations so as to enable Landlord to pay the contractor, architect or engineer without advancing Landlord's own funds. At Landlord's election, Tenant shall deposit with Landlord prior to the commencement of the Alterations the estimated cost thereof or such lesser portion as Landlord shall specify, to be held and applied to the cost as incurred. Any surplus funds shall be returned to Tenant when the Alterations have been paid for in full. (f) Landlord may delegate some or all of its authority and responsibilities under this Section 8 to its managing agent, which may be an affiliate of Landlord. 9. Liens. Tenant shall keep the Premises, Building and Project free from any liens arising out of any work performed, materials furnished or obligations incurred by or on behalf of Tenant. Landlord shall have the right to post and keep posted on the Premises any notices that may be provided by law or which Landlord may deem to be proper for the protection of Landlord, the Premises, Building and/or Project from such liens. Tenant shall remove any such lien by bond or otherwise within ten (10) days after notice from Landlord, and if Tenant shall fail to do so, Landlord may, but shall not be obligated to, pay the amount necessary to remove such lien without being 12 <PAGE> 16 responsible for investigating the validity thereof. Any amount so paid by Landlord shall be deemed additional rent under this Lease payable upon demand, without limitation as to other remedies available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord's title to the Premises, Building or Project to any liens whether claimed by operation of law or express or implied contract. 10. Repairs. By entry hereunder Tenant accepts the Premises as being in the condition in which Landlord is obligated to deliver the Premises, subject to any applicable provisions of Exhibit "C". Tenant shall, at all times during the Term and at Tenant's sole cost and expense, keep the Premises (including, without limitation, any Tenant Improvements, Alterations and Tenant's furniture, fixtures, equipment and personal property in the Premises) in good condition and repair (regardless of the cost therefor and/or the time remaining on the Term), ordinary wear and tear, damage thereto by fire (unless caused by or contributed to by Tenant), earthquake, act of God or the elements excepted. Tenant hereby waives all rights to make repairs at the expense of Landlord or in lieu thereof to vacate the Premises and all rights under Sections 1932(1), 1941 and 1942 of the California Civil Code or any successor statute. Tenant shall at the end of the Term surrender to Landlord the Premises and all Alterations thereto that are to remain in the Premises in the same condition as when received, ordinary wear and tear and damage by fire (unless the same is caused by or contributed to by Tenant), earthquake, act of God or the elements excepted. Tenant shall remove all of its personal property and equipment from the Premises prior to the expiration of the Term or earlier termination of this Lease, and if Tenant fails to remove the same, Landlord may do so and store or dispose of the same at Tenant's sole cost. Landlord has no obligation and has made no promise to alter, remodel, improve, repair, decorate or paint the Premises, except as specifically otherwise provided in this Lease. No representations respecting the condition of the Premises, the Building or the Project have been made by Landlord to Tenant, except as specifically provided in this Lease. 11. Destruction or Damage. (a) In the event the Premises or the portion of the Building necessary for Tenant's occupancy are damaged by fire, earthquake, act of God, the elements or other casualty, within sixty (60) days after such event, Landlord shall notify Tenant of the estimated time, in Landlord's reasonable judgment, required for repair or restoration. If such estimated time for repair or restoration is less than one hundred eighty (180) days after the date of casualty and the cost of repair is covered by insurance maintained by Landlord, Landlord shall forthwith repair or restore the Premises or the portion of the Building necessary for Tenant's occupancy, to the extent of insurance proceeds received on account of such casualty. If the time for repair or restoration is in excess of one hundred eighty (180) days after the date of casualty or the cost of repair is not covered by Landlord's insurance, Landlord shall elect, in the same notice Tenant, either (i) to repair or restore the Premises or the portion of the building necessary for Tenant's occupancy, in which event this Lease shall continue in full force and effect (unless Tenant exercises its right to terminate this Lease as provided below), or (ii) to terminate this Lease, in which event this Lease shall terminate as of the date of such fire or other casualty. In the event Landlord is obligated or elects to repair the Premises pursuant to this Section 11 (unless Tenant exercises its right to terminate this Lease as provided below), this Lease shall remain in full force and effect except that, if such damage is not the result of the act or omission of Tenant or Tenant's employees, agents, representatives, contractors or invitees, an abatement of rental shall be allowed Tenant for such part of the Premises as shall be rendered unusable by Tenant (but only to the extent actually not used by Tenant) in the conduct of its business during the time such part is so unusable. Notwithstanding the foregoing, if Landlord's estimate states that the repair or restoration of the subject casualty damage will take longer than twelve (12) calender months to substantially complete, then Tenant shall have the right to terminate this Lease by written notice delivered to Landlord within five (5) days following the date of Landlord's estimate, and Tenant's failure to deliver such termination notice shall be deemed an election by Tenant not to terminate the Lease. (b) Notwithstanding anything to the contrary contained in this Section 11, in the event of casualty to the Premises or the portion of the Building necessary for Tenant's occupancy during the final 12 months of the 13 <PAGE> 17 Term which is estimated by Landlord in good faith to require in excess of thirty (30) days to repair or restore (with respect to Landlord's termination right) or ninety (90) days to repair or restore (with respect to Tenant's termination right), then either Landlord or Tenant may elect to terminate this Lease by written notice to Tenant delivered within five (5) days of the date of Landlord's estimate. (c) If the Premises or the Building are to be repaired or restored under this Section 11, Landlord shall repair or restore the Building and all improvements in the Premises other than any of Tenant's furniture, fixtures, equipment, personal property, and any Tenant Improvements and Alterations made by or for Tenant. Tenant shall be responsible for the repair or restoration of any such Tenant's furniture, fixtures, equipment, personal property, and any Tenant Improvements and Alterations made by or for Tenant, provided that any repair of such Tenant Improvements or Alterations shall be performed by Landlord, at Tenant's cost. (d) Landlord and Tenant acknowledge that their respective rights and obligations in the event of any damage to or destruction of the Premises or the Building are to be governed exclusively by this Lease and waive their respective rights under Sections 1932(2) and 1933(4) of the California Civil Code or any successor statute. 12. Insurance. (a) Tenant shall, during the Term hereof and any other period of occupancy, at its sole cost and expense, keep in full force and effect the following insurance: (1) All Risk insurance (including, without limitation, sprinkler leakage and earthquake sprinkler leakage endorsements) upon property of every description and kind owned by Tenant and located in the Building or for which Tenant is legally liable or installed by or on behalf of Tenant, including, without limitation, furniture, fixtures, personal property, any Tenant Improvements (pursuant to Exhibit "C") and Alterations, in an amount not less than ninety-five percent (95%) of the full replacement cost thereof, and providing business interruption coverage for a period of one year. All such insurance policies shall name Tenant as named insured thereunder, shall name Landlord, and, at Landlord's request, Landlord's "Mortgagees" (as defined in Section 23 below), as loss payees thereunder, all as their respective interests may appear. Not less frequently than once every three (3) years, Landlord shall have the right to notify Tenant that it elects to have the replacement value redetermined by an insurance company or insurance consultant. The redetermination shall be made promptly and in accordance with the rules and practices of the Board of Fire Underwriters, or a like board recognized and generally accepted by the insurance company, and each party shall be promptly notified of the results by the company. The insurance required under this Lease shall be adjusted according to the redetermination. (2) Commercial general liability insurance coverage, including personal injury, bodily injury, broad form property damage and contractual liability (covering the indemnity contained in Section 13), in amount not less than $1,000,000.00 per occurrence, $2,000,000.00 aggregate. All such insurance policies shall name Tenant as named insured thereunder and shall name Landlord and Landlord's managing agent and Mortgagees as additional insureds thereunder. Such insurance shall be written as primary coverage and non-contributing with respect to any insurance maintained by Landlord. (3) Workers' Compensation and Employer's Liability Insurance in form and amounts not less than that required by applicable law, but in no event will the coverage provided under Tenant's Employer's Liability Insurance be less than five hundred thousand dollars ($500,000.00) or such other amount as Landlord may be reasonably require. (4) Any other form or forms of insurance as Landlord may reasonably require from time to time in form, in amounts, and for insurance risks against which a prudent tenant of a comparable size and in a comparable business would protect itself. (b) All policies shall be written in a form reasonably satisfactory to Landlord and shall be taken out with insurance companies 14 <PAGE> 18 admitted in the State of California holding a General Policyholders Rating of "A-" and a Financial Rating of VII or better, as set forth in the most current issue of Best's Insurance Reports. Prior to the date Tenant takes possession of any part of the Premises, Tenant shall deliver to Landlord copies of policies or certificates evidencing the existence of the amounts and forms of coverage required hereunder, and said certificates shall provide that no such policy shall be cancelable or reducible in coverage except after thirty (30) days' prior written notice to Landlord and any additional insureds or loss payees thereunder. Tenant shall, within ten (10) days prior to the expiration of such policies, furnish Landlord with renewals or binders thereof, or if Tenant fails to do so, Landlord may order such insurance and charge the cost thereof shall be due from Tenant to Landlord upon demand as additional rent. (c) During the Term, Landlord shall insure the Project (excluding any property which Tenant is obligated to insure under Sections 12(a) above) against damage with All Risk insurance and comprehensive general liability insurance, in such amounts and with such deductibles as Landlord considers appropriate. Landlord may, but shall not be obligated to, obtain and carry any other form or forms of insurance as it deems advisable. Notwithstanding any contribution by Tenant to the cost of insurance premiums as provided herein, Tenant acknowledges that it has no right to receive any proceeds from any insurance policies carried by Landlord. (d) If Tenant's occupancy or business in or upon the Premises, whether or not Landlord has consented to the same, results in any increase in premiums for the insurance periodically carried by Landlord with respect to the Building or the Project, Tenant shall pay as additional rent any such increase in premiums within ten (10) days after being billed therefor by Landlord. (e) All policies of insurance required hereunder, including, without limitation, Workers' Compensation and Employer's Liability insurance, shall include a clause or endorsement denying the insurer any rights of subrogation against the other party to the extent rights have been waived by the insured before the occurrence of injury or loss. Landlord and Tenant waive any rights of recovery against the other for injury or loss due to hazards covered by policies of insurance, including, without limitation, Workers' Compensation and Employers' Liability insurance, to the extent insurance proceeds cover the injury or loss. 13 Indemnification. Tenant hereby waives all claims against Landlord for damage to any property or injury or death of any person in, upon or about the Premises or Project arising at any time and from any cause other than by reason of gross negligence or wilful misconduct of Landlord, its employees, agents or representatives. Tenant shall indemnify, defend and hold harmless Landlord from and against any and all claims, demands, losses, liabilities, damages, costs and/or expenses (including, without limitation, reasonable attorneys' fees and expenses) arising out of (a) any injury to or death of any person or damage to or destruction of property attributable to or resulting from the use of the Premises by Tenant, except such as is caused by gross negligence or willful misconduct of Landlord, its employees, agents or representatives, (b) the acts or omissions of Tenant or any of Tenant's employees, agents, representatives or invitees (including, without limitation, acts or omissions with respect to Hazardous Materials), and/or (c) any breach of this Lease by Tenant. The provisions of this Section shall survive the expiration of the Term or earlier termination of this Lease. 14. Compliance with Legal Requirements. Tenant, at its sole cost and expense (regardless of the cost therefor or the time remaining on the term), shall promptly comply with all Laws (including, without limitation, Laws respecting accessibility or use of the Premises by disabled persons) now in force or which may hereafter be in force, with the requirements of any board of fire underwriters or other similar body now or hereafter constituted, with any directive or occupancy certificate issued pursuant to any Law by any public officer or officers, as well as the provisions of all recorded documents affecting the Premises, insofar as any thereof relate to or affect the condition, use or occupancy of the Premises, excluding structural changes to the Premises or Building required to comply therewith, which structural changes shall be performed by Landlord as an item of Operating Expenses in accordance with Section l(d) above (except that Tenant shall be solely responsible for the cost of such structural changes as additional rent within 15 <PAGE> 19 ten (10) days following Landlord's demand, to the extent such structural changes are required as a result of Tenant's acts, specific use of the Premises, or improvements or Alterations made by or for Tenant). Notwithstanding the foregoing, Tenant shall not be required to pay any cost or expense, either directly or as part of Operating Expenses, for causing the Project, or any portion thereof, as the same exist on the Commencement Date, to comply with applicable Laws (including, without limitation, the Americans with Disabilities Act) as such Laws are in effect on the Commencement Date; provided, however, that Tenant will be responsible for any such compliance costs which result from Tenant's specific use of the Premises and/or from the existence of any improvements and/or Alterations constructed by or on behalf of Tenant. 15. Assignment and Subletting. (a) Tenant shall not, without the prior consent of Landlord, which consent shall not be unreasonably withheld, assign or hypothecate this Lease or any interest herein, sublet the Premises or any part thereof, or permit the use of the Premises by any party other than Tenant. This Lease shall not, nor shall any interest herein, be assignable as to the interest of Tenant by operation of law without the consent of Landlord, which consent shall not be unreasonably withheld. Any of the foregoing acts without such consent shall be void and shall, at the option of Landlord, terminate this Lease. For purposes hereof, in the event Tenant is a partnership, a withdrawal or change of the managing partner, or partners owning more than a controlling interest in the partnership in one or more transfers, or if Tenant is a corporation, any transfer of a majority of its stock in one or more transfers, or the transfer by the controlling shareholder of so much of its stock that it is no longer the controlling shareholder, shall constitute a voluntary assignment and shall be subject to the provisions of this Section 15; provided, however, that in the case of a transfer of a majority of a corporation's stock, Tenant may, concurrently with Tenant's written notice to Landlord of any such transfer (which shall be delivered not less than thirty (30) days prior to the effective date thereof), increase its security deposit to an amount which is equal to six (6) months' then current Base Rent, in which case Landlord's consent to such voluntary assignment shall not be required. In connection with each consent requested by Tenant, Tenant shall submit to Landlord not less than twenty (20) days prior to the effective date of the proposed transaction, the terms of the proposed transaction, the identity of the parties to the transaction, the proposed documentation for the transaction and all other information reasonably requested by Landlord concerning the proposed transaction and the parties involved therein. Within sixty (60) days of receipt of such request for consent and other required information, Landlord shall elect either to: (i) consent to such proposed transaction (ii) refuse such consent, which refusal shall be on reasonable grounds or (iii) elect to terminate this Lease effective as of the date Tenant proposes to assign this Lease or sublet all of the Premises, or in the case of sublease of twenty-five percent (25%) or more of the Rentable Area of the Premises for more than twelve (12) months, terminate this Lease as to the portion of the Premises proposed to be sublet as of the date of such proposed partial sublease. Nothing contained in this Section 15 shall be deemed a waiver of Landlord's right to elect to terminate this Lease in accordance with clause (iii) of the foregoing sentence including, but not limited to, Landlord's failure to exercise its right to terminate this Lease with respect to any previous assignment or subletting. Further, Tenant understands and acknowledges that Landlord's option to terminate this Lease rather than approve the assignment thereof or the subletting of all or any portion of the Premises, is a material inducement for Landlord's agreeing to lease the Premises to Tenant upon the terms and conditions herein set forth. Notwithstanding the foregoing, Landlord shall respond to Tenant's request for consent to an assignment or subletting within thirty (30) days if (i) Tenant includes the following notice (in bold, all capitalized twelve point type) in its request for consent: "LANDLORD MUST RESPOND TO THIS REQUEST FOR CONSENT WITHIN THIRTY (30) DAYS FOLLOWING ITS RECEIPT HEREOF" and (ii) such request by Tenant otherwise complies with the requirements of this Section 15. (b) Without limiting the other instances in which it may be reasonable for Landlord to withhold its consent to an assignment or subletting, Landlord and Tenant acknowledge that it shall be reasonable for Landlord to withhold its consent in the following instances: (1) if at the time consent is requested or at any time prior to the granting of consent, 16 <PAGE> 20 Tenant is in default under this lease or would be in default under this Lease but for the pendency of any grace or cure period under Section 18 below (2) if the proposed assignee or subtenant is a governmental agency (3) if the proposed assignee or subtenant is an existing tenants in the Project or Landlord is then or within the prior 6 months has been negotiating with such assignee or subtenant for the lease of space within the Project (4) if, in Landlord's reasonable judgment, the use of the Premises by the proposed assignee or subtenant would not be comparable to the types of office use by other tenants in the Project, would entail any alterations which would lessen the value of the leasehold improvements in the Premises, would result in more than a reasonable number of occupants per floor, or would require increased services by Landlord (5) if, in Landlord's reasonable judgment, the financial worth of the proposed assignee or subtenant does not meet the credit standards applied by Landlord for other tenants under leases with comparable terms, or the character, reputation, or business of the proposed assignee or subtenant is not consistent with the quality of the other tenancies in the Building or (6) if the subletting is of less than the entire Premises. (c) In the case of an assignment, one-half of any sums or other economic consideration received by Tenant as a result of such assignment shall be paid to Landlord after first deducting the unamortized cost of leasehold improvements paid for by Tenant, and the cost of any real estate commissions and other generally recognized and available concessions incurred by Tenant in connection with such assignment. In the case of a subletting, one-half of any sums or economic consideration received by Tenant as a result of such subletting shall be paid to Landlord after first deducting (1) the rental due hereunder, prorated to reflect only rental allocable to the sublet portion of the Premises, (2) the cost of leasehold improvements made to the sublet portion of the Premises at Tenant's cost, amortized over the term of this Lease except for leasehold improvements made for the specific benefit of the subtenant, which shall be amortized over the term of the sublease, and (3) the cost of any real estate commissions and other generally recognized and available concessions incurred by Tenant in connection with such subletting, amortized over the term of the sublease. (d) Regardless of Landlord's consent, no subletting or assignment shall release Tenant of Tenant's obligation or alter the primary liability of Tenant to pay the rental and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rental by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to one assignment or subletting shall not be deemed consent to any subsequent assignment or subletting or a waiver of any of the terms of this Lease. No assignee or subtenant shall have a right further to assign or sublet without Landlord's prior consent in accordance with this Section 15. No sublease, once consented to by Landlord, shall be modified or terminated by Tenant without Landlord's prior consent, which consent shall not be unreasonably withheld. In the event of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such assignee or successor. Landlord may consent to subsequent assignments or subletting of this Lease or amendments or modifications to this Lease with assignees of Tenant, without notifying Tenant, or any successor of Tenant, and without obtaining its or their consent thereto, and such action shall not relieve Tenant of liability under this Lease. (e) A condition to Landlord's consent to any assignment or other transfer of this Lease shall be the delivery to Landlord of a true copy of the fully executed instrument of assignment or transfer, and the delivery to Landlord of an agreement executed by the assignee or transferee in form and substance satisfactory to Landlord and expressly enforceable by Landlord, whereby the assignee or transferee assumes and agrees to be bound by all of the provisions of this Lease and to perform all of the obligations of Tenant hereunder. As a condition to Landlord's consent to any sublease, Landlord may require that such sublease include among other items, provisions stating (i) that it is subject and subordinate to this Lease and to all Mortgages and ground leases affecting the Project, (ii) Landlord shall be a third party beneficiary of the obligations of Tenant's subtenant and may enforce the terms of said sublease against said subtenant, and (iii) that in the event of a termination of this Lease for any reason, including without limitation, a voluntary surrender by Tenant or mutual cancellation by Landlord and Tenant, 17 <PAGE> 21 or in the event of any re-entry or repossession of the Premises by Landlord, such sublease shall terminate, except that Landlord, at its option, may elect to continue such sublease in effect and require that such subtenant attorn to and recognize Landlord as its landlord under such sublease. (f) In the event Tenant shall assign this Lease or sublet the Premises or request the consent of Landlord to any assignment, subletting, hypothecation or other action requiring Landlord's consent hereunder, then Tenant shall pay Landlord's reasonable attorneys' fees incurred in connection therewith. (g) Notwithstanding the foregoing, the original Tenant hereunder may without Landlord's consent assign its interest in this Lease or sublet all or a portion of the Premises to any affiliate of Tenant provided that (i) Tenant gives Landlord thirty (30) days prior written notice and delivers to Landlord concurrently with such notice all of the information which would otherwise be required in connection with a request for consent, (ii) the transaction complies with the provisions of Section 15(e) above and (iii) the assignee or subtenant has a financial worth sufficient, in Landlord's reasonable and good faith determination, to fulfil the obligations of Tenant under this Lease; provided, however, Landlord shall evaluate financial worth using the same standards Landlord then applies to similar tenants under leases with comparable terms, in each case as reasonably determined by Landlord. For purposes of the preceding sentence, an "affiliate" means any person or entity that directly, or indirectly through one or more intermediaries, controls or is controlled by, or is under common control with, Tenant. The original Tenant hereunder shall also have the right, without Landlord's consent, to (i) assign its interest in this Lease to a corporation (or other business entity) into which it may merge or which may otherwise succeed to all or substantially all of said original Tenant's assets or (ii) to a one (1) time transfer of a majority of its stock (through one or a series of transactions) to any person or entity that is not an affiliate of Tenant, provided that, in each case, (x) Tenant provides Landlord with written notice of such assignment within ten (10) days following the completion thereof, (y) the transaction complies with the provisions of Section 15(e) above, and (z) the assignee, after giving effect to said merger or acquisition of assets, has a financial worth sufficient, in Landlord's reasonable and good faith determination, to fulfil the obligations of Tenant under this Lease; provided, however, that Landlord shall evaluate financial worth using the same standards Landlord then applies to similar tenants under leases with comparable terms, in each case as reasonably determined by Landlord. Any assignment or subletting which does not, in Landlord's reasonable and good faith determination, comply with the conditions of stated in this Section 15(g) shall be deemed to be void and of no force or effect. 16. Rules. Tenant shall faithfully observe and comply with the rules and regulations attached hereto as Exhibit "D", and after notice thereof, all reasonable modifications thereof and additions thereto from time to time promulgated in writing by Landlord, which may include parking regulations designed to ensure more orderly and efficient parking at the Project. Landlord shall not be responsible to Tenant for the nonperformance by any other tenant or occupant of the Building or the Project of any such rules and regulations. Landlord shall endeavor to enforce said rules and regulations in a non-discriminatory manner. 17. Entry by Landlord. Landlord may enter the Premises at reasonable hours and, except in the case of a perceived emergency, after reasonable notice (but in no event shall more than one (1) day's notice be required), to (a) inspect the same (b) exhibit the same to prospective purchasers, lenders or tenants (c) determine whether Tenant is complying with its obligations under this Lease (d) supply janitor service and any other service to be provided by Landlord to Tenant hereunder (e) post notices on non-responsibility (f) make repairs or perform maintenance required of Landlord under the terms hereof, make repairs to any adjoining space or utility services, or make repairs, alterations or improvements to any other portion of the Building or (g) cure any default in the performance of Tenant's obligations under this Lease pursuant to Section 19 (c) below provided, however, that all such work shall be done as promptly as reasonably possible and so as to minimize unreasonable interference with the operation of Tenant's business from the Premises to the extent reasonably practicable. Tenant 18 <PAGE> 22 hereby waives any claim for damages for any inconvenience to or interference with Tenant's business or any loss of occupancy or quiet enjoyment of the Premises occasioned by such entry. Landlord shall at all times have and retain a key with which to unlock all of the doors in, on or about the Premises (excluding Tenant's vaults, safes and similar areas designated in writing by Tenant in advance) and Landlord shall have the right to use any and all means which Landlord may deem proper to open Tenant's doors in an emergency in order to obtain entry to the Premises, and any entry to the Premises obtained by Landlord in an emergency shall not be construed or deemed to be a forcible or unlawful entry into or a detainer of the Premises or an eviction, actual or constructive, of Tenant from the Premises or any portion thereof. 18 Tenant's Default. The following events shall constitute events of default under this Lease: (a) a failure by Tenant to pay when due any rent or other sum payable hereunder and the continuation of such default for a period of three (3) days after written notice that the same is due; (b) a failure by Tenant to perform any of the other terms, covenants, agreements or conditions contained herein, and, if the failure is curable, the continuation of such failure for a period of fifteen (15) days after notice by Landlord; provided, however, that if the nature of Tenant's obligation is such that more than fifteen (15) days are required for performance, then Tenant shall not be in default if Tenant commences performance within such fifteen (15) day period and thereafter diligently prosecutes the same to completion; (c) the bankruptcy or insolvency of Tenant, transfer by Tenant in fraud of creditors, an assignment by Tenant for the benefit of creditors, or the commencement of any proceedings of any kind by or against Tenant under any provision of the Federal Bankruptcy Act or under any other insolvency, bankruptcy or reorganization act unless, in the event any such proceedings are involuntary, Tenant is discharged from the same within sixty (60) days thereafter; (d) the appointment of a receiver for a substantial part of the assets of Tenant; (e) the abandonment of the Premises for a period of twenty (20) consecutive days or more (or an aggregate of forty (40) days during any three (3) calendar months) and a concurrent failure to pay rent; (f) the levy upon this Lease or any estate of Tenant hereunder by any attachment or execution and the failure to have such attachment or execution vacated within thirty (30) days thereafter; or (g) the breach or default by Tenant or an affiliate of Tenant under any other lease or other agreement under which Tenant or such affiliate occupies or previously occupied other space at the Project. Any notice of default to be given pursuant to this Section 18 shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 or any similar or successor statute. 19. Landlord's Remedies. (a) In the event of any default by Tenant pursuant to Section 18 above, in addition to any other remedies available to Landlord at law or in equity, Landlord shall have the immediate option to terminate this Lease and all rights of Tenant hereunder. In the event that Landlord shall elect to so terminate this Lease, then Landlord may recover from Tenant: (i) the worth at the time of award of any unpaid rent which had been earned at the time of such termination plus (ii) the worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided plus (iii) the worth at the time of award of the amount by which the unpaid rent for the balance of the Term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided plus (iv) any other amount necessary to compensate Landlord 19 <PAGE> 23 for all the detriment proximately caused by Tenant's failure to perform Tenant's obligations under this Lease or which in the ordinary course of things would be likely to result therefrom. As used in clauses (i) and (ii) of this Section 19(a) above, the "worth at the time of award" is computed by allowing interest at the Interest Rate. As used in clause (iii) of this Section 19(a) above, the "worth at the time of award" is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%. (b) In the event of any such default by Tenant and/or Tenant's abandonment of the Premises (as defined in Section 18(d) above), Landlord shall also have the right to reenter the Premises and remove all persons and property therefrom by summary proceedings or otherwise such property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of Tenant or disposed of in a reasonable manner by Landlord. In the event Landlord shall elect to reenter as provided above, or shall take possession of the Premises pursuant to legal proceedings or pursuant to any notice provided by law, and if Landlord does not elect to terminate this Lease as provided by law, then Landlord may from time to time, without terminating this Lease, either recover all rental as it becomes due or relet the Premises or any part thereof for such term and at such rental or rentals and upon such other terms and conditions as Landlord in its sole discretion may deem advisable, with the right to make alterations and repairs to the Premises. It is the intention of the parties that in addition to, and without limitation upon, all other rights and remedies set forth in this Lease, Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee's breach and abandonment and recover rent as it becomes due). In the event that Landlord shall elect to relet, then rentals received by Landlord from such reletting shall be applied first, to the payment of any indebtedness, other than Base Rent due hereunder, owed by Tenant to Landlord second, to the payment of any cost of such reletting third, to the payment of the cost of any alterations and repairs to the Premises fourth, to the payment of Base Rent due and unpaid hereunder and the residue, if any, shall be held by Landlord and applied in payment of future rent as the same may become due and payable hereunder. Should that portion of such rentals received from such reletting during any month, which is applied to the payment of rent hereunder, be less than the rent payable during that month by Tenant hereunder, then Tenant shall pay such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs and expenses incurred by Landlord in such reletting, including but not limited to brokerage commissions, or in making alterations and repairs not covered by the rentals received from such reletting. No reentry or taking possession of the Premises by Landlord pursuant to this Section 19, shall be construed as an election to terminate this Lease unless a written notice of such intention be given by Landlord to Tenant or unless the termination thereof be decreed by a court of competent jurisdiction. Landlord may at any time after such reletting elect to terminate this Lease for any such default by Tenant. (c) If Tenant fails to perform any covenant or condition to be performed by Tenant, Landlord may, but without obligation to do so, perform such covenant or condition at its option, after notice to Tenant. All costs incurred by Landlord in so performing shall immediately be reimbursed to Landlord by Tenant, together with interest at the Interest Rate computed from the due date. Any performance by Landlord of Tenant's obligations shall not waive or cure such default. Landlord may perform Tenant's defaulted obligations at Tenant's sole cost and expense without notice in the case of any emergency. All costs and expenses incurred by Landlord, including reasonable attorneys' fees (whether or not legal proceedings are instituted), in collecting rent or enforcing the obligations of Tenant under the Lease shall be paid by Tenant to Landlord upon demand. Tenant's obligations pursuant to this Section 19 (c) shall survive the expiration or earlier termination of this Lease. (d) Tenant hereby waives, for itself and all persons claiming by and under Tenant, all rights and privileges which it might have under any present or future Laws to redeem the Premises or reinstate or to continue the Lease after being dispossessed or ejected from the Premises. All rights, options and remedies of Landlord contained in this Lease shall be construed and held to be cumulative, and no one of them shall be exclusive of the other, 20 <PAGE> 24 and Landlord shall have the right to pursue any one or all of such remedies or any other remedy or relief which may be provided by law, whether or not stated in this Lease. (e) In addition to the remedies described in Sections 19(a)-(d) above, Landlord shall be entitled to recover from Tenant under this Lease all amounts necessary to compensate Landlord for all the detriment proximately caused by any breach or default described in Section 18(g) above. The remedy provided for in this Section 19(e) shall be in addition to any and all remedies available in the other lease or agreement to which such breach or default pertains. 20. Landlord's Default and Tenant's Remedies. Landlord shall not be in default hereunder unless Landlord fails to perform the obligations required of Landlord within a reasonable time, but in no event later than thirty (30) days after written notice by Tenant to Landlord specifying wherein Landlord has failed to perform such obligation provided, however, that if the nature of Landlord's obligation is such that more than thirty (30) days are required for performance, then Landlord shall not be in default if Landlord commences performance within such 30 day period and thereafter diligently prosecutes the same to completion. In no event shall Tenant have the right to terminate this Lease or withhold rent as a result of Landlord's default and Tenant's remedies shall be limited to an action for damages, injunction or specific performance of this Lease. Notwithstanding anything contained in this Lease to the contrary, Tenant and all successors and assigns covenant and agree that, in the event of any actual or alleged failure, breach or default hereunder by Landlord, their sole and exclusive remedy shall be against Landlord's interest in the Project. Tenant and all such successors and assigns agree that the obligations of Landlord under this Lease do not constitute personal obligations of the individual partners, whether general or limited, members, directors, officers or shareholders of Landlord, and Tenant shall not seek recourse against the individual partners, directors, officers or shareholders of Landlord or any of their personal assets for satisfaction of any liability with respect to this Lease. 21. Attorneys' Fees. In the event of any dispute between Landlord or Tenant, whether or not suit is filed, or if either Landlord or Tenant shall institute any action or proceeding against the other party relating to this Lease, the non-prevailing party in such action or proceeding shall reimburse the prevailing party for its disbursements incurred in connection therewith and for its reasonable attorneys' fees, whether or not such action or proceeding is pursued to judgment. In addition to the foregoing award of attorneys' fees to the prevailing party, the prevailing party in any action or proceeding on this Lease shall be entitled to its reasonable attorneys' fees incurred in any post-judgment proceedings to collect or enforce any such judgment. This provision is separate and several and shall survive (i) the expiration or earlier termination of this Lease and (ii) the merger of this Lease into any judgment on this Lease. 22. Eminent Domain. If all or any part of the Premises shall be taken as a result of the exercise of the power of eminent domain or sale in lieu of such taking (collectively, any "Taking"), this Lease shall terminate as to the part so taken as of the date of Taking, and, in the case of a partial Taking, either Landlord or Tenant shall have the right to terminate this Lease as to the balance of the Premises by notice to the other within thirty (30) days after such date, provided, however, that a condition to the exercise by Tenant of such right to terminate shall be that the portion of the Premises taken shall be of such extent and nature as substantially to handicap, impede or impair Tenant's use of the balance of the Premises. In the event of the Taking of a material portion of the Project (whether or not the Premises is affected thereby), Landlord shall have the right to terminate this Lease by notice to Tenant within 30 days following such Taking. In the event of any Taking, Landlord shall be entitled to any and all compensation, damages, income, rent, awards, or any interest therein whatsoever which may be paid or made in connection therewith, and Tenant shall have no claim against Landlord for the value of any unexpired Term of this Lease or otherwise. Notwithstanding the foregoing, Tenant may apply to the condemning party for a separate award for Tenant's relocation costs and loss of good will, unless such award diminishes the award otherwise payable to Landlord, in which case Tenant shall be precluded from making such an application. In the event of a partial Taking of the Premises which does not result in a termination of this 21 <PAGE> 25 Lease, the monthly rental thereafter to be paid shall be equitably reduced. The parties agree that their respective rights and obligations in the event of any Taking shall be governed by the terms of this Lease and hereby waive any and all rights under Section 1265.130 of the California Code of Civil Procedure. 23. Subordination. (a) This Lease and Tenant's rights hereunder shall be subject and subordinate to any ground lease, mortgage, deed of trust, or other hypothecation or security device (collectively, any "Mortgage"), now or hereafter placed by Landlord upon the Project, Building or other real property of which the Premises is a part, to any and all advances made on the security thereof, and to all renewals, modifications, consolidations, replacements and extensions thereof. Tenant agrees that the ground lessors, mortgagees, trust deed beneficiaries and other lienholders under any such Mortgages (collectively, "Mortgagees") shall have no duty, liability or obligation to perform any of the obligations of Landlord under this Lease, but that in the event of Landlord's default with respect to any such obligation, Tenant will give any Mortgagee whose name and address have been furnished Tenant in writing for such purpose notice of Landlord's default and allow such Mortgagee thirty (30) days (or if more than thirty (30) days is required to effect such cure, such additional time as may be necessary) following receipt of such notice for the cure of said default before invoking any remedies Tenant may have by reason thereof. If any Mortgagee shall elect to have this Lease and/or Tenant's rights hereunder superior to the lien of its Mortgage and shall give written notice thereof to Tenant, this Lease and such rights shall be deemed prior to such Mortgage, notwithstanding the relative dates of the documentation or recordation thereof (b) Notwithstanding any such subordination, and at the election of a Mortgagee or any other party who acquires ownership of the Premises by reason of the exercise of rights under a Mortgage or through a deed in lieu of foreclosure, Tenant agrees to attorn to such Mortgagee or other party, and in the event of such exercise of remedies and such election, such new owner shall not: (i) be liable for any act or omission of any prior landlord or with respect to events occurring prior to acquisition of ownership, (ii) be subject to any offsets or defenses which Tenant might have against any prior landlord, (iii) be bound by prepayment of more than one month's rent, or (iv) be required to perform any obligations of any prior landlord under the Lease. (c) The agreements contained in this Section 23 shall be effective without the execution of any further documents and shall survive the exercise of remedies under a Mortgage provided, however, that, upon written request from Landlord or a Mortgagee, Tenant and Landlord shall execute such further writings as may be reasonably required to separately document any of the matters provided for herein. (d) Notwithstanding Sections 23(a) and (b) above, Tenant's obligation to subordinate this Lease to any Mortgage(s) entered into after the date of this Lease shall be subject to Tenant's receiving assurance (a "Non-Disturbance Agreement") from the Mortgagee that Tenant's possession and this Lease shall not be disturbed as long as (i) no default by Tenant (or event which would constitute a default with the passage of time or the giving of notice) has occurred and (ii) Tenant attorns to said Mortgagee as provided above. Landlord shall also use its best efforts to obtain a Non-Disturbance Agreement from the Mortgagee, if any, holding a Mortgage against the Project as of the date of this Lease; provided, however, that Tenant shall pay all costs and expenses, including, without limitation, attorneys' fees, incurred by Landlord in connection with such efforts. The form and content of any Non-Disturbance Agreement required under this Section 23(d) shall be determined by the Mortgagee, in its sole and absolute discretion; provided, that, with respect to Mortgages entered into after the date of this Lease, Landlord shall use reasonable efforts (without expending money or incurring any obligation) to assist Tenant in causing the Mortgagee thereunder to use a commercially reasonable form of Non-Disturbance Agreement. 24. Sale. In the event the original Landlord hereunder, or any successor owner of the Project, shall sell or convey the Project, all liabilities and obligations on the part of the original Landlord, or such successor owner, under this Lease accruing thereafter shall terminate, and 22 <PAGE> 26 thereupon all such liabilities and obligations shall be binding upon the new owner. Tenant agrees to attorn to such new owner. 25. Estoppel Certificate. At any time and from time to time, but in no event later than ten (10) business days after request by Landlord, Tenant shall execute, acknowledge, and deliver to Landlord, promptly upon request, a certificate certifying (a) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect, as modified, and stating the date and nature of the modification), (b) the amount of the Base Rent and most recent Escalation Rent, if any, and the date to which such rental has been paid, (c) that no notice has been received by Tenant of any default which has not been cured, except as to defaults specified in the certificate, (d) that no default of Landlord is claimed by Tenant, except as to defaults specified in the certificate, and (e) such other matters as may be reasonably requested by Landlord. Any such certificate may be relied upon by any prospective purchaser or existing or prospective Mortgagee under any Mortgage on the project or Building. Tenant's failure to deliver such statement within such time shall constitute a default by Tenant under this Lease and shall be conclusive upon Tenant (i) that this Lease is in full force and effect, without modification except as may be represented by Landlord, (ii) that not more than one (1) monthly installment of Base Rent and Escalation Rent in the amount specified by Landlord has been paid in advance, and (iii) that there are no uncured defaults in Landlord's performance. Within ten (10) days following Landlord's request from time to time during the Term, Tenant shall deliver to Landlord Tenant's current financial statement and financial statements for the two (2) years prior to the current financial statement year, prepared in accordance with generally accepted accounting principles, consistently applied. Landlord shall use reasonable efforts not to divulge any confidential financial information of Tenant contained in an estoppel certificate to any third parties (other than Landlord's officers, directors, employees, accountants, attorneys and others as reasonably required in the conduct of Landlord's business, or as otherwise required by applicable securities Laws); except in the case of any litigation concerning this Lease, in which event Landlord shall use reasonable efforts to keep such financial terms confidential. 26. Project Planning. In the event Landlord requires the Premises for use in conjunction with another suite or for other reasons connected with Project planning, upon notifying Tenant in writing, Landlord may, subject to Tenant's approval as provided below, move Tenant to other premises in the Corporate Center (the "New Premises"), at Landlord's sole cost and expense, and the terms and conditions of this Lease shall remain in full force and effect, except that a revised Exhibit "B" shall become part of this Lease and shall reflect the location of the New Premises and Section 1 of this Lease shall be amended to include and state all correct data as to the New Premises (except that Tenant's rental obligations under this Lease shall not be increased as a result of such relocation to the New Premises). Landlord shall provide Tenant with at least thirty (30) days' prior written notice of its desire to relocate the Premises, which notice shall describe in reasonable detail the location and configuration of the proposed New Premises. Tenant shall approve or disapprove the proposed New Premises within ten (10) days of the date of Landlord's notice, which approval shall not be unreasonably withheld and shall be deemed granted if not withheld, in writing, within such ten (10) day period; provided, however, that Tenant may not withhold its approval of the New Premises if the size, quality, configuration and window lines of the proposed New Premises are substantially similar to the original Premises. 27. No Light, Air, or View Easement. Any diminution or shutting off of light, air or view by any structure which may be erected on lands adjacent to the Building shall in no way affect this Lease or impose any liability on Landlord. 28. Holding Over. If Tenant holds possession of the Premises after expiration of the Term of this Lease or any termination of this Lease, Tenant shall become a tenant at sufferance only, at a monthly rental equivalent to 150% of the then prevailing monthly rental paid by Tenant at the expiration of the Term or termination of this Lease, payable in advance on or before the first day of each month, and otherwise subject to the terms, covenants and conditions herein specified, so far as applicable. Acceptance by Landlord of rent after such expiration or earlier termination shall not result in a 23 <PAGE> 27 renewal or extension of this Lease. If Tenant fails to surrender the Premises upon the expiration of this Lease despite demand to do so by Landlord, Tenant shall indemnify, defend and hold harmless Landlord from and against any and all claims, demands, losses, liabilities, damages, costs and/or expenses (including, without limitation, reasonable attorneys, fees and expenses) arising out of such failure to surrender including, without limitation, any claim made by any succeeding tenant. 29. Security Deposit. Concurrently with its execution of this Lease, Tenant shall deposit with Landlord the sum specified in the Basic Lease Information (the "Security Deposit"). The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all the provisions of this Lease to be performed or observed by Tenant. If Tenant fails to pay rent or other sums due hereunder, or otherwise defaults with respect to any provision of this Lease, Landlord may use, apply or retain all or any portion of the Security Deposit for the payment of any rent or other sum in default or for the payment of any other sum to which Landlord may become obligated by reason of Tenant's default, or to compensate Landlord for any loss or damage which Landlord may suffer thereby. If Landlord so uses or applies all or any portion of the Security Deposit, Tenant shall within ten (10) days after demand therefor deposit cash with Landlord in an amount sufficient to restore the Security Deposit to the full amount thereof and Tenant's failure to do so shall be a material breach of this Lease. Landlord shall not be required to keep the Security Deposit separate from its general accounts. If Tenant performs all of Tenant's obligations hereunder, the Security Deposit, or so much thereof as has not theretofore been applied by Landlord, shall be returned, without interest, to Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's interest hereunder) at the expiration of the Term hereof, and after Tenant has vacated the Premises. No trust relationship is created herein between Landlord and Tenant with respect to the Security Deposit. If this Lease provides for periodic increases in Base Rent, Lessee shall, within ten (10) days after demand by Landlord, increase the amount of the Security Deposit to equal the Base Rent then in effect. 30. Waiver. The waiver by Landlord of any agreement, condition or provision herein contained shall not be deemed to be a waiver of any subsequent breach of the same or any other agreement, condition or provision herein contained, nor shall any custom or practice which may grow up between the parties in the administration of the terms hereof be construed to waive or to lessen the right of Landlord to insist upon the performance by Tenant in strict accordance with such terms. The subsequent acceptance of rental hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any agreement, condition or provision of this Lease, other than the failure of Tenant to pay the particular rental so accepted, regardless of Landlord's knowledge of the preceding breach at the time of acceptance of the rental. 31.

Tenant acknowledges, however, that Landlord may provide or not provide any additional parking spaces requested by Tenant in Landlord's sole and absolute discretion. Landlord may assign any unreserved and unassigned parking spaces and/or make all or a portion of such spaces preferred and/or reserved, if it determines in its sole discretion that it is necessary for orderly and efficient parking.

The monument signage right granted hereunder shall automatically terminate if such signage is not placed within one (1) year of the Commencement Date. All signage, including, without limitation, the location, design, size, color, and type, shall be subject to (i) Landlord's prior written consent, which shall not be unreasonably withheld, (ii) Building signage standards, if any, and (iii) all applicable Laws. 41. Must Take Space. On the six (6) month anniversary of the Commencement Date (the "Must Take Space Commencement Date"), the Premises leased to Tenant shall be increased to include the approximately five thousand (5,000) square feet of Rentable Area identified on Exhibit "B" as the "Must Take Space" (the "Must Take Space"). Following the Must Take Space Commencement Date, Tenant's use and occupancy of the Must Take Space shall be for a term co-terminus with the Lease Term, and otherwise subject to all applicable terms and conditions of this Lease; provided, however, that Landlord shall have no obligation to improve the Must Take Space for Tenant.

Expansion Space. Provided that no default by Tenant (which shall include any mater which would constitute a default either with the passage of time or the giving of notice) has occurred prior to the time the "Expansion Space Notice" (as such term is defined below) is received by Landlord or thereafter until the date on which the "Tenant's Exercise Notice" (as such term is defined below) is received by Landlord, Tenant shall have the ongoing option for the lease of any leaseable space in the Building (the "Expansion Space") to the extent the same becomes available for lease to Tenant (which for purposes hereof shall mean that such space is not then occupied or subject to lease or option or right for lease extension or premises expansion by any other tenant or person) during the initial Term, exercisable as follows: If Tenant desires to expand the Premises to include any Expansion Space, Tenant shall deliver at any time during the initial Term deliver written notice thereof to Landlord (the "Expansion Space Notice"). Promptly following receipt of the Expansion Space Notice, Landlord shall deliver to Tenant written notice of any Expansion Space which is available or will become available during the twelve (12) month period following the date of Tenant's Expansion Space Notice, and Tenant shall have ten (10) business days following the date of such notice from Landlord to elect by written notice to Landlord (the "Tenant's Exercise Notice") to lease (commencing immediately upon availability) all of any one (1) configuration of such Expansion Space for a term co-terminus with the Lease Term and otherwise subject to all applicable terms and conditions of this Lease; provided, however, that Landlord shall have no obligation to improve the Expansion Space for Tenant. If (i) Tenant does not deliver an Expansion Space Notice, or (ii) after delivery of Tenant's Expansion Space Notice and receipt of notice of any available space from Landlord, Tenant does not deliver Tenant's Exercise Notice within such ten (10) business day period electing to lease such Expansion Space, Landlord may proceed to lease such Expansion Space to any party upon any terms and conditions as Landlord desires. If Tenant delivers the Expansion Space Notice, then (i) the "Premises" shall thereafter be deemed for all purposes to include the Expansion Space and (ii) Tenant's Base Rent, Percentage Share of Building Operating Expenses, and Building Tax Expenses, Security Deposit, and other matters in this Lease pertaining to the amount of Rentable Area contained within the Premises shall be adjusted accordingly, as reasonably determined by Landlord. Landlord and Tenant shall within thirty (30) days following Landlord's receipt of the Tenant's Exercise Notice execute an amendment to this Lease prepared by Landlord to reflect the addition to the Premises of the Expansion Space, and Landlord may, but without obligation to do so, declare the Tenant's Exercise Notice to be null and void if Tenant fails to execute such amendment. Notwithstanding anything to the contrary contained in this paragraph, Tenant may not exercise its rights under this Section 42 after the last day of the forty-second (42) month of the initial Term unless it concurrently exercises its option to extend the Term by the Option Term as provided in Section 2 above. 43. Miscellaneous. The words "Landlord" and "Tenant" as used herein shall include the plural as well as the singular. If there be more than one Tenant, the obligations hereunder imposed upon Tenant shall be joint and several. Time is of the essence of this Lease and each and all of its provisions. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

Plans. Landlord and Tenant hereby approve the space plans and Building standard specifications (collectively, the "Space Plans") for the construction of certain improvements, WHICH SHALL NOT INCLUDE TENANT'S TELEPHONE, COMPUTER, AND DATA SYSTEMS, FURNITURE, OR OTHER PERSONAL IMPROVEMENTS DESIRED BY TENANT (the "Tenant Improvements") to be permanently affixed to the Premises, which Space Plans are described on Schedule 1 attached hereto and incorporated herein by this reference. Promptly following the execution of this Lease, Landlord shall cause Landlord's architect to prepare final plans and specifications (the "Final Plans") for the Tenant Improvements, in accordance with the Space Plans. Such Final Plans shall be submitted by Landlord's architect to Landlord and Tenant for approval, which approval shall not be unreasonably withheld and shall be granted so long as such Final Plans are in accordance with the approved Space Plans; provided, however, that any deviation from the Space Plans requested by Tenant as a part of the Final Plans shall be subject to the provisions of Section 3 of this Exhibit "C" respecting "Change Orders" (as hereinafter defined). Upon written approval of the Final Plans by the parties, Landlord shall be authorized to proceed with the construction of the Tenant Improvements in accordance with the Final Plans. All Tenant Improvements shall be constructed using then current Building standard materials and colors. In the event of any conflict among this Exhibit "C", the Space Plans, and any notes attached to the Space Plans, the notes attached to the Space Plans shall prevail. For example, if the notes attached to the Space Plans provide that the costs associated with a portion of the work described in said Space Plans is to be paid for by Tenant, then Tenant shall be obligated to pay such costs, notwithstanding the fact that this Exhibit "C" provides that Landlord shall perform the Tenant Improvements (as shown in the Space Plans) at its cost and expense. 2. Construction of the Tenant Improvements. Subject to the provisions of Section 3 below, Landlord shall construct, or cause the construction of, the Tenant Improvements in accordance with the approved Final Plans, at Landlord's sole cost and expense. In addition to Landlord's obligation to undertake the Tenant Improvements described in Schedule 1 attached hereto, Landlord shall also pay to Tenant four thousand dollars ($4,000.00) to reimburse Tenant for the costs of its telephone, computer and data systems, furniture and other personal improvements placed by Tenant in the Premises. Landlord shall make such payment to Tenant within thirty (30) business days following the Commencement Date. 3. Deviations from the Final Plans. Tenant shall be liable for the increased cost of the design and construction of the Tenant Improvements resulting from any Change Orders in accordance with the provisions of this Section 3, plus a construction administration fee to The Johnston Group, an affiliate of Landlord, in an amount equal to ten percent (10%) of such cost. In the event of any deviation from the Space Plans requested by Tenant as a part of the Final Plans pursuant to Section 1 above, and/or any change to any item of Final Plans following the approval thereof by Landlord pursuant to Section 1 above, Tenant shall submit to Landlord a written request for a change order (the "Change Order Request"), detailing the desired change. If Landlord approves Tenant's Change Order Request, Landlord shall promptly thereafter issue to Tenant a statement (the "Change Order Statement") indicating the net increase in the cost of design and construction of the Tenant Improvements resulting from the implementation of such Change Order Request (including, without limitation, reasonable contractor's fees for profit, overhead and general conditions in connection with such Change Order Request). Within 3 days following receipt of such Change Order Statement from Landlord, Tenant shall notify Landlord in writing whether Tenant elects to incorporate the Change Order Request into the Final Plans, provided that it shall be a condition to the effectiveness of such an election to so incorporate the Change Order Request that Tenant pay to Landlord the amount specified on the Change Order Statement. If Tenant so elects to incorporate the Change Order Request into the Final Plans, the Change Order Request shall become a "Change Order" and Landlord may retain the amount delivered by Tenant pursuant to the Change Order Statement therefor as Tenant's contribution to the cost of such Change Order. If the adoption of a Change Order causes a delay in the Commencement Date that would have otherwise been established in the absence of such Change Order, such delay shall be a "Tenant Delay" (as defined in Section 4(b) below). In addition, in the event that the net cost of construction of the Tenant Improvements increases due to changes requested by EXHIBIT "C" - PAGE 1 <PAGE> 35 any applicable governmental authority in the Tenant Improvements as set forth in the Final Plans approved by Landlord and Tenant pursuant to Section 1 above, Tenant shall be pay to Landlord the amount of such increased costs within 10 days after Tenant's receipt from Landlord of written notice thereof. 4.

TO BE INSTALLED BY TENANT AND/OR UNDER THE SUPERVISION OF LANDLORD'S CONTRACTOR. (b) If there shall be a delay or there are delays in the occurrence of the Commencement Date as a direct, indirect, partial, or total result of any of the following (in any such case, a "Tenant Delay"): (i) Tenant's failure to timely perform its obligations under this Exhibit "C" or the other provisions of this Lease requiring Tenant's approval, (ii) Tenant's request for any Change Orders and/or the implementation thereof, (iii) Tenant's requirement for materials, components, finishes or improvements which are not available in a commercially reasonable time given the anticipated date of substantial completion of the Premises, or which are different from Building standards, or (iv) any other acts or omissions of Tenant, or its agents, employees and/or contractors, then, notwithstanding anything to the contrary set forth in this Lease (including, without limitation, this Exhibit "C") and regardless of the actual date of the Commencement Date, the Commencement Date shall be the date on which the Commencement Date would have occurred if no Tenant Delay or Tenant Delays, as set forth above, had occurred. If Tenant Delays exist, then upon the substantial completion of the Premises, Landlord shall notify Tenant of (1) the aggregate period of the Tenant Delays and (2) the Commencement Date as determined pursuant hereto. Tenant shall, within five (5) days following receipt of such notice, perform or cause to be performed all obligations under this Lease (including, without limitation, the payment of rent) that have accrued from the Commencement Date as determined pursuant hereto, to the date on which Tenant received Landlord's notice, and the Commencement Date shall, for all purposes under this Lease, be the Commencement Date as determined pursuant hereto.

EXHIBIT "D" - PAGE 3 <PAGE> 44 EXHIBIT "F" FURNITURE SYSTEMS EXHIBIT "F" <PAGE> 45 FIRST AMENDMENT TO OFFICE LEASE THIS FIRST AMENDMENT TO OFFICE LEASE ("Amendment") is entered as of March 22, 2000 by and between Malibu Canyon Office Partners, LLC, a California limited liability company ("Landlord"), and Ixia, a California corporation (formerly known as Ixia Communications, Inc., a California corporation) ("Tenant"), with reference to the following facts: R E C I T A L S A. Landlord and Tenant previously entered into that certain Office Lease dated November 5, 1999 (the "Lease") pursuant to which Tenant leased from Landlord certain Premises comprising a portion of the Building commonly known as 26601 W. Agoura Road, Calabasas, CA 91302 (the "Premises"); B. Tenant desires to expand the Premises to include the entirety of the aforementioned Building, and Landlord is willing to lease such additional space to Tenant subject to and as provided for in this Amendment; and C. Landlord and Tenant desire to modify the Lease as provided in this Amendment, NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows: A G R E E M E N T 4. Expansion Premises. From and after the "Expansion Premises Commencement Date" (as defined in Section 2 below), the Premises leased to Tenant pursuant to the Lease shall for all purposes be deemed to include that certain space (the "Expansion Premises") located on the third (3rd) floor of the Building, as more particularly described in Exhibit "A" attached hereto and incorporated by this reference herein. The Expansion Premises is agreed by the parties to contain twenty thousand square feet of Rentable Area. The entire Premises (after giving effect to the Expansion Premises and the initial "Must Take Space" under Section 41 of the Lease) is agreed by the parties to contain forty-five thousand (45,000) square feet of Rentable Area in the Building. With the exception of the Tenant Improvements provided for in Section 6 below, the Expansion Premises shall be leased on an entirely "AS IS" basis, Tenant hereby agreeing that Tenant has thoroughly inspected the Expansion Premises and is completely satisfied with the condition of the same. Therefore, except as specifically provided in Section 6 below, Tenant shall accept the Expansion Premises without Landlord having any obligation for the improvement or alteration thereof. 5. Expansion Premises Commencement Date. The term of Tenant's lease of the Expansion Premises under the Lease shall commence on June 1, 2000 (the "Expansion Space Commencement Date"), and shall be for a term co-terminus with the Lease Term (after giving effect to the extension under Section 9 below)). 6. Base Rent; Percentage Share. Commencing upon the Expansion Premises Commencement Date, (i) the Base Rent payable by Tenant for the entire Premises (ie the original Premises, the initial Must Take Space and the Expansion Premises) shall be one and 50/100 dollars ($1.50) per month for each square foot of Rentable Area contained in the Premises and (ii) Tenant's Percentage Share of Building Operating Expenses and Building Tax Expenses shall be one hundred percent (100%). Tenant's Percentage Share 1 <PAGE> 46 of Operating Expenses attributable to any restaurant, fitness center or similar amenities shall continue to be calculated as provided in Section 1(j) of the Lease. 7. Security Deposit. Concurrently with its execution of this Amendment, Tenant shall deposit an additional Security Deposit with Landlord in the amount of two hundred twenty-five thousand dollars ($225,000.00) (the "Additional Security Deposit"), which amount equals three (3) months" Base Rent for the entire Premises (including all Must Take Space). That portion, if any, of the Additional Security Deposit which has not been applied by Landlord in accordance with the Lease shall earn interest at the rate of six percent (6%) per annum; provided, however, that upon any default by Tenant (including any matter which would constitute a default either with the passage of time or the giving of notice), (i) such interest shall immediately cease to accrue and (ii) any interest previously earned shall automatically be forfeited by Tenant (ie deemed not to have accrued). Landlord will refund the Additional Security Deposit, together with accrued interest thereon, if any, (to the extent not previously applied by Landlord in accordance with the Lease) to Tenant upon the completion of an initial public offering of Tenant's stock on either the New York Stock Exchange or the National Association of Securities Dealers Exchange if, and only if, such initial public offering generates immediately available cash to Tenant of forty million dollars ($40,000,000.00) or more (excluding debt or debt instruments); provided, that Landlord shall have no obligation to refund any portion of the Additional Security Deposit if a default (including any matter which would constitute a default either with the passage of time or the giving of notice) by Tenant has occurred. If Landlord is entitled to apply any portion of Tenant's Security Deposit under the Lease, Landlord may apply Tenant's Additional Security Deposit before applying the original Security Deposit previously made by Tenant. Except for Landlord's obligation, if any, to pay interest on and to otherwise refund the Additional Security Deposit as provided in this Amendment, the Additional Security Deposit shall be governed by the provisions of Section 29 of the Lease. 8. Parking. Commencing upon the Expansion Premises Commencement Date and in addition to any parking allocated to Tenant in Section 35 of the original Lease, Tenant shall be entitled, at no additional cost to Tenant, to three point eight (3.8) non-exclusive surface parking spaces for each one thousand square feet of Usable Area located within the Expansion Premises, plus two (2) additional subterranean parking spaces located in such areas of the Building as Landlord may from time to time designate. Subject to availability, as from time to time determined by Landlord in its sole and absolute discretion, Tenant may also lease (i) fifteen reserved subterranean parking spaces, at a rate of sixty-five dollars ($65.00) per month per space, to be located in such areas of the Building as Landlord may from time to time designate, and (ii) nineteen (19) non-exclusive surface parking spaces, at no additional charge to Tenant, to be located in the northwest corner of the Project, as more particularly shown in Exhibit "B" attached hereto and incorporated by this reference herein. Any parking space described in clause (ii) of the preceding sentence which is not used by Tenant during normal business hours shall, at Landlord's option after one (1) business day's notice to Tenant, be forfeited by Tenant. In addition to the monthly parking fees, if any, provided for in the Lease, Tenant shall also pay to Landlord the following sums for each subterranean parking card provided to Tenant: (i) a ten dollar ($10.00) security deposit and (ii) a fifteen dollar ($15.00) non-refundable programming fee, in each case on a per card basis. Landlord shall refund the aforementioned per card security deposit to Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's interest hereunder) for each card that Tenant returns to Landlord (in good working condition) at the expiration of the Term hereof; provided that (i) Tenant must have vacated the Premises and (ii) Landlord may retain said security deposit to the extent that the Security Deposit received by Landlord under the Lease is not sufficient to pay any rent or other sums owing to Landlord under this Lease. Tenant shall deliver the aforementioned security deposit and programming fee to Landlord 2 <PAGE> 47 concurrently with its request for subterranean parking, unless this Lease initially provides for subterranean parking, in which case Tenant shall deliver such sums concurrently with its execution of this Lease. Except as expressly provided in this Section 5 to the contrary, any parking spaces allocated to Tenant under this Amendment shall be subject to the terms and provisions of Section 35 of the Lease. 9. Tenant Improvements. Landlord, at Tenant's sole cost and expense but subject to the "Landlord's Contribution" (as such term is defined below), shall improve the Expansion Premises, the "Second Must Take Space" (as defined in Section 10 below) and the interior non-structural portions of the Building not previously occupied by Tenant consistent with space plans and working drawings to be prepared by Tenant and approved by Landlord in accordance with Section 8 of the Lease (said improvements are hereinafter referred to as the "Tenant Improvements"). Landlord shall have the right to reasonably approve or disapprove Tenant's space planner and/or architect. Tenant shall also pay The Johnston Group, an affiliate of Landlord, a construction administration fee in an amount equal to ten percent (10%) of the total costs of design and construction of the Tenant Improvements. Landlord and Tenant acknowledge and agree that the Tenant Improvements may be completed in one (1) or more phases, and that Tenant may present Landlord with additional sets of space plans and working drawings with respect to each such phase; provided, however, that all Tenant Improvements shall be completed on or before May 31, 2002. Landlord shall contribute up to four hundred thirty-three thousand dollars ($433,000.00) (the "Landlord's Contribution") solely towards (i) Tenant's reasonable, actual and verifiable costs for the space plans and working drawings for the Tenant Improvements as described above and (ii) the construction costs, including permit costs and the aforementioned construction administrative fee, for the Tenant Improvements, but excluding Tenant's telephone, computer, and data systems, furniture, or other personal improvements desired by Tenant. Landlord shall have no obligation to pay for design or construction costs of the Tenant Improvements or for construction administration fees to the extent the same exceed the Landlord's Contribution as set forth above. If Landlord estimates that the costs of Tenant Improvements (including the aforementioned construction administration fees) will, in the aggregate, exceed the Landlord's Contribution, Tenant shall pay such estimated overage to Landlord prior to commencement of construction of the pending or proposed phase of Tenant Improvements. Tenant shall not be entitled to any credit, offset or refund if Landlord is able to construct the Tenant Improvements described in the approved space plans and/or working drawings for less than the Landlord's Contribution, or if the Tenant Improvements are not completed by May 31, 2002. Subject to Force Majeure Events, Landlord shall use its best efforts to complete construction of the initial phase of the Tenant improvements within sixty (60) days following the date on which Tenant provides Landlord with a permit permitting Landlord to commence construction of all aspects of such Tenant Improvements. Tenant's initial set of space plans and/or working drawings for the Tenant Improvements shall provide for material improvements to all of the Building's lobbies, the Building's second (2nd) and third (3rd) floor corridors, the bathrooms contained in what was previously "Common Area" of the Building (ie without giving effect to the addition to the Premises of the Expansion Space), and the elevator cabs of the Building. All permits shall be processed and obtained by Tenant. 10. Sublease of Expansion Space. The original Tenant hereunder may sublet all or any portions of the third (3rd) floor of the Building leased by Tenant subject to the restrictions contained in Section 15(g) of the Lease applicable to the six thousand (6,000) square feet of Rentable Area of the original Premises which the original Tenant may sublease without the Landlord's consent; provided, however that the term(s) of any such sublease (including option periods) may be up to twenty-four (24) months from the Expansion Space Commencement Date as opposed to the eighteen (18) month limitation established in said Section 15(g) of the Lease. 3 <PAGE> 48 11. Signage. In addition to Tenant's existing signage rights under the Lease, Tenant may install non-exclusive freeway facing Building signage identifying Tenant's business name. Tenant shall also have the exclusive right to place its business name on the existing monument sign located in front of, or immediately adjacent to, the Building; provided, however, that Tenant may upon thirty (30) days" notice to Landlord place on said monument sign the business name of up to two (2) subtenants occupying space in the Building in accordance with the Lease. The signage rights granted in this Section 8 shall commence upon the Expansion Space Commencement Date, and shall automatically terminate if placement of said signage is not completed within one (1) year following the Expansion Space Commencement Date. All such signage, including, without limitation, the size, dimensions, color and location thereof, shall (i) be subject to Landlord's prior approval, (ii) conform to Building standards from time to time adopted by Landlord and (iii) and comply in all respects with all applicable Laws. Tenant shall pay all costs and expenses associated with placement of the signage described in this Section 8. 12. Commencement Date for Initial Premises; Initial Must Take Space Commencement Date; Extension of Term. Landlord and Tenant agree that (i) the "Commencement Date" for the initial Premises under the Lease will be March 27, 2000, (ii) the "Must Take Space Commencement Date" under Section 41 of the Lease shall be no later than July 1, 2000 and (iii) the Expiration Date of the Term of the Lease for the entire Premises is hereby extended to and including May 31, 2007. 13. Second Must Take Space. On December 1, 2000 (the "Second Must Take Space Commencement Date"), the Premises leased to Tenant shall be increased to include the Rentable Area identified on Exhibit "A" as the "Second Must Take Space" (the "Second Must Take Space"), which the parties agree contains five thousand square feet of Rentable Area. Following the Second Must Take Space Commencement Date, Tenant's use and occupancy of the Second Must Take Space shall be for a term co-terminus with the Lease Term (after giving effect to the extension of the Term under Section 9 above), and shall otherwise be subject to all applicable terms and conditions of this Lease; provided, however, that Landlord shall have no obligation to improve the Second Must Take Space beyond the improvements to be constructed pursuant to Section 6 above. Tenant shall not be required to pay Base Rent for the Second Must Take Space until the Second Must Take Space Commencement Date or such earlier date on which Tenant commences to occupy any portion of the Second Must Take Space, at which time Tenant's Base Rent and other matters in this Lease pertaining to the amount of Rentable Area contained within the Premises shall be adjusted accordingly, as reasonably determined by Landlord. 14. Existing Expansion Rights. Tenant's rights under Section 42 of the Lease are hereby deleted in their entirety, and shall be of no further force or effect. 15. Telecommunications Services; Business Loss. Landlord shall have no obligation or liability whatsoever to Tenant in connection with any telecommunications or similar services which Tenant receives from others, notwithstanding the fact that Landlord may have (i) introduced the provider or facilitator thereof to Tenant or (ii) a preexisting or affiliate relationship with such provider or facilitator, and Tenant hereby waives any and all claims against Landlord with respect thereto. Under no circumstances will Landlord be liable to Tenant for damages to Tenant's business or loss of income therefrom. 16. Other Terms of Occupancy. Except as expressly provided in this Amendment to the contrary, Tenant's occupancy of the Expansion Premises and Second Must Take Space shall be subject to all of the terms and conditions contained in the Lease, including, without limitation, payment of and escalations to Base Rent, Building Operating 4 <PAGE> 49 Expenses and Building Tax Expenses based upon the addition to the Premises of the Expansion Premises and the Second Must Take Space. 17. Miscellaneous. a. Landlord and Tenant acknowledge and agree that this Amendment is subject to Landlord's receiving from its mortgagee(s) approval of all of the terms contained herein. b. The terms used herein shall have the same meaning as those defined in the Lease unless expressly contradicted in this Amendment. c. The submission of the Amendment is only an invitation to deal and shall not be deemed an offer by Landlord. Only a fully executed and delivered Amendment shall bind the parties hereto. d. In the event of a conflict between the provisions of this Amendment and those of the Lease, the provisions of this Amendment shall control. Except for purposes of determining whether a conflict exists between the Lease and this Amendment, the term "Lease" as used herein shall include the provisions of this Amendment. The Lease and this Amendment are deemed to have been jointly prepared by the parties, and shall not be interpreted against any party as drafter. e.
