Landlord and Tenant hereby agree as follows: 1. PREMISES -------- Subject to the contents of this Lease, Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises described in the Basic Lease Information Summary (the "Summary") (the "Premises") in the building described in the Summary (the "Building"), as shown on the floor plan (s) attached as Exhibit A to this Lease. The Building is part of an office complex consisting of 1650-1730 S. Amphlett Blvd. (the "Complex"). All measurements of area contained in this Lease are conclusively agreed to be correct and binding upon the parties, even if a subsequent measurement of any one of these areas determines that it is more or less than the amount of area reflected in the Lease. Any such subsequent determination that the area is more or less than shown in this Lease shall not result in a change in any of the computations of rent, improvement allowances or other matters described in this Lease where area is a factor. 2. TERM ---- The term of this lease (the "Term") commences on the earlier of (a) the Target Commencement Date; or (b) the date on which Tenant first occupies all or any portion of the Premises. The dates on which the Term commences and terminates pursuant to this Article 2 are herein called the "Commencement Date and the "Expiration Date," respectively. If, for any reason, Landlord cannot deliver possession of the Premises to Tenant on or prior to the Commencement Date, this Lease shall not be void or voidable nor shall Landlord be liable to Tenant for any loss or damage resulting therefrom. In such case, Tenant shall not pay any rent and the Commencement Date shall not occur until such date as Landlord can deliver the Premises, provided, however that if Landlord's failure to deliver the Premises is attributable to any action or inaction by Tenant, then the Commencement Date shall not be advanced to the date on which possession of the Premises is delivered to Tenant and Landlord shall be entitled to full performance by Tenant (including payment of rent) from the date the Premises would have been ready for delivery to Tenant but for Tenant's action or inaction. 3. RENT, ADDITIONAL CHARGES ------------------------ 3.1 Base Rent. Tenant will pay to Landlord during the Term the monthly Base Rent set forth in the Summary (the "Base Rent") in consecutive monthly installments on or before the first day of each calendar month, in advance, at the address specified for Landlord in the Summary, or such other place as Landlord may designate in writing, without any prior demand and without any deductions or setoff. Upon execution of this Lease, Tenant shall pay to Landlord the first month's Base Rent. If the Commencement Date occurs on a day other than the first day of a calendar month, or the Expiration Date occurs on a day other than the last day of a calendar month, then the rental for such fractional month will be prorated based on a thirty (30) day month. 3.2 Additional Charges. Tenant shall pay to Landlord all charges and other amounts required to be paid by Tenant under this Lease (herein called "Additional Charges") as additional rent at the place where the Base Rent is payable. Landlord will have the same remedies for a default in the payment of any Additional Charges as for a default in the payment of Base Rent. (Base Rent and Additional Charges are sometimes collectively referred to herein as "rent.") 3.3 Late Charge. If Tenant fails to pay any Base Rent or additional Charges within five (5) days after the date the same is due and payable, such unpaid amounts will be subject to a late payment 3. <PAGE> charge equal to ten percent (10%) of the unpaid mounts in each instance. The late payment charge has been agreed upon by Landlord and Tenant, after negotiation, as a reasonable estimate of the additional administrative costs and detriment that will be incurred by Landlord as a result of any such failure by Tenant, the actual costs thereof being extremely difficult if not impossible to determine. The late payment charge constitutes liquidated damages to compensate Landlord for its damages resulting from such failure to pay and shall be paid to Landlord together with such unpaid amounts. 4. ADDITIONAL CHARGES FOR EXPENSES AND REAL ESTATE TAXES ----------------------------------------------------- 4.1 Definition of Expenses. For purposes of this Article 4, the following terms shall have the meanings set forth in this Section 4.1. "Tenant's Building Percentage Share", Tenant's Common Area Expense percentage Share" and "Base Year" shall be as set forth in the Summary. Landlord may adjust these percentages as a result of any change in the rentable area of the Premises or the total rentable area of the Building or the other building in the Complex. "Computation Year" means each calendar year during the Term, including any partial calendar year in which the Term may commence or terminate. "Real Estate Taxes", "Building Expenses", "Insurance Expenses" and "Common Area Expenses" are defined in Exhibit B to this Lease. --------- 4.2 Payment of Charges. From the first day of the thirteenth month of the Term through the Expiration Date, Tenant shall pay to Landlord as Additional Charges (i) Tenant's Building Share of the total dollar increase, if any, in Building Expenses attributable to each Computation Year over Building Expenses for the Base Year, (ii) Tenant's Building Share of the total dollar increase, if any, in Real Estate Taxes attributable to each Computation Year over Real Estate Taxes for the Base Year, (iii) Tenant's Building Share of the total dollar increase, if any, in Insurance Expenses attributable to each Computation Year over Insurance Expenses for the Base Year and (iv) Tenant's Common Area Expense Share of the total dollar increase, if any, in Common Area Expenses attributable to each Computation Year over Common Area Expenses for the Base Year. During the last month of each Computation Year or as soon thereafter as practicable, Landlord shall give to Tenant notice of Landlord's estimate of the amounts payable by Tenant for the following Computation Year. On or before the first day of each month during the following Computation Year, Tenant shall pay to Landlord one-twelfth (l/12th) of the estimated amounts, provided that until Landlord gives such notice, Tenant shall continue to pay on the basis of the prior year's estimate until the first day of the calendar month after Landlord gives such notice. If at any time or times Landlord determines that the amounts payable by Tenant for the current Computation Year will vary from its estimate given to Tenant, Landlord, by notice to Tenant, may revise its estimate for the Computation Year, and subsequent payments for the Computation year shall be based upon the revised estimate. Following the end of each Computation Year, Landlord shall deliver to Tenant a statement of amounts payable for the Computation Year. If the statement shows an amount owing by Tenant that is less than the payments for such Computation Year previously made by Tenant, and if no Event of Default is outstanding, Landlord shall credit the amount to the next payments of rent due. If the statement shows an amount owing by Tenant that is more than the estimated payments for the Computation Year previously made by Tenant, Tenant shall pay the deficiency to Landlord within thirty (30) days after delivery of such statement. The respective obligations of Landlord and Tenant under this Section 4.2 shall survive the Expiration Date. If the Commencement Date is a day other than the first day of a Computation Year or the Expiration Date is a day other than the last day of a Computation Year, the adjustment in rent pursuant to this Section 4.2 for such Computation Year shall be prorated based on a 365-day year. 5. USE --- 5.1 Limitations. Tenant shall use and continuously occupy the Premises solely for the use or uses specified in the Summary and for no other use or purpose. Tenant shall take no action, nor permit any action to be taken, in or about the Premises that 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 cancellation of any insurance policy covering all or any part of the Building or any of its contents, or which will in any way injure or interfere with the rights of other tenants or occupants of the Building, nor shall Tenant use or allow the Premises to be used for unlawful or objectionable purpose, nor cause, maintain or permit any nuisance in, on or about the Premises, nor commit nor suffer to be committed any waste in, on or upon the Premises. Tenant shall not use or operate any equipment, machinery or apparatus within the Premises which will injure, vibrate or shake the Premises or the Building, overload existing electrical systems or other utilities or equipment servicing the Premises or Building, or impair the efficient operation of the sprinkler system (if 4. <PAGE> any) or the heating, ventilating and air conditioning equipment within or servicing the Premises or the Building. Tenant shall not cause or permit any Hazardous Materials to be brought upon, stored, used, generated or released or disposed of on, under, from or about the Premises, Building or Complex (including, without limitation, the soil and groundwater thereunder) without the prior written consent of Landlord. As used herein, the term "Hazardous Material," means any hazardous or toxic substance, material or waste which is or becomes regulated by any local governmental authority, the State of California or the United States Government.

(42 U.S.C. Section 6903), or (iii) defined as "hazardous substance" pursuant to Section 101 of the Comprehensive Enviromental Response, Compensation and Liability Act, 42 U.A.C., Section 9601 et seq. (42 U.S.C. 6901). 5.2 Common Area. Tenant shall have a non-exclusive right to use the Common Area, provided, however, that Tenant's use of the Common Area shall be subject to such rules and regulations as Landlord shall make from time to time. As used in this Lease, the term "Common Area" shall mean the area and improvements designated by Landlord from time to time as "Common Area" for the use and enjoyment of tenants of the Complex. Landlord reserves the right, from time to time, to: (i) utilize portions of the Common Area for entertainment, displays, product shows, the leasing of kiosks or such other uses as, in Landlord's judgment, tend to attract the public, change the shape, size, location and extent of improvements on the Common Area; (ii) eliminate or add any improvements; and (iii) temporarily close any portion of the Common Areas for repairs, remodeling and/or alteration, to prevent a public dedication or the accrual of prescriptive rights, or for any other reason deemed sufficient by Landlord. 6. CONSTRUCTION OF PREMISES; BUILDING CHANGES ------------------------------------------ Landlord shall construct the Premises and perform the work and make the installations in the Premises substantially as set forth in Exhibit "A" to ----------- this Lease (the "floor plan"). Landlord reserves the right, at any time and from time to time, to make alterations, additions, repairs or improvements to or in or to decrease the size or area of all or any part of the Building, the fixtures and equipment therein and the areas outside the' Building, and the Common Area, and to change the arrangement and/or location of entrances or passageways, doors, corridors, elevators, stairs, toilets and other public parts of the Building, provided that any such alterations or additions shall not materially diminish the quality or quantity of services being provided to the Premises or adversely affect the functional utilization of the Premises. 7. ALTERATIONS ----------- 7.1 Tenant's Trade Fixtures. During the Term of this Lease, Tenant may install Tenant's trade fixtures which may be removed without material injury to the Premises on the Premises without the prior consent of Landlord. All Tenant's trade fixtures shall remain Tenant's property. Tenant's trade fixtures shall not include the initial Tenant Improvements paid for with the funds of Landlord nor any improvements thereafter made to the Premises by Landlord at any time with Landlord's Funds. 7.2 Consent Requirement for Alterations. Tenant shall make no alterations, additions or improvements (collectively, "Alterations") to the ----------- Premises or any part thereof without obtaining the prior written consent of Landlord. Such consent may be granted or withheld in Landlord's sole and absolute discretion.

All such alterations, additions or improvements must be done in compliance with all applicable laws, in a good and workmanlike manner and diligently prosecuted to completion. Tenant shall deliver to Landlord upon commencement of such work, a copy of the building permit with respect thereto. All such work shall be performed so as not to obstruct the access to the Premises of any other tenant in the 5. <PAGE> Building or Complex. Should Tenant make any alterations without Landlord's prior written consent, Landlord shall have the right, in addition to and without limitation of any right or remedy Landlord may have under this Lease, at law or in equity, to require the Tenant to remove all or some of the alterations at Tenant's sole cost and restore the Premises to the same condition as existed prior to undertaking the alterations. Tenant shall notify Landlord in writing at least ten (10) days prior to the commencement of any such work in or about the Premises and Landlord shall have the right at any time and from time to time to post and maintain notices of non-responsibility in or about the Premises. 7.3 Possession.

At the expiration or sooner termination of the Term, all Tenant's Alterations shall be surrendered to Landlord and shall then become Landlord's property, and Landlord shall have no obligation to reimburse Tenant for all or any portion of the value or cost thereof; provided, however, that if Landlord requires Tenant to remove any Tenant's Alterations, Tenant shall so remove such Tenant's Alterations, and Tenant shall restore the Premises to the condition which existed prior to the installation of such Tenant's Alterations, prior to the expiration or sooner termination of the Term. 8.

If the necessity for such maintenance and repairs is in any way caused by the act, neglect, fault, or omission of Tenant, its agents, servants, employees or invitees, Tenant shall pay promptly to Landlord the reasonable cost of such maintenance and repairs. Landlord shall not be liable for any failure to make any such repairs or to perform any such maintenance unless Landlord receives notice of the need for such repairs or maintenance from Tenant and fails to make such repairs or perform such maintenance for a reasonable period of time following such notice by Tenant. Rent shall not abate nor shall Landlord be liable as a result of any injury to or interference with Tenant's business arising from the making of any repairs, or the performance of any maintenance, in or to any portion of the Building, the Premises or the Common Area, excepting the negligence or willful misconduct of Landlord, Agents, servants, employees, licensees or contractors. "As used herein, the term "Building Systems" shall mean all systems and equipment (including, without limitations, plumbing, HVAC, electrical, fire/life safety, elevator, and security systems) that serve ther entire Building or portions of the Building other than simply the respective premises of the tenants of the Building." 8.3 Tenant's Failure to Repair.

All such sums paid by Landlord and all expenses incurred by it in connection therewith (including without limitation reasonable counsel fees) shall be payable to Landlord by Tenant upon demand. Landlord shall have the right at all times to post and keep posted on the Premises any notices permitted or required by law or that Landlord shall deem proper for the protection of Landlord, the Premises, and the Building, from mechanics' and material men's liens. Tenant shall give to Landlord at least five (5) business days' prior written notice of commencement of any repair or construction on the Premises. 10. COMPLIANCE WITH LAWS AND INSURANCE REQUIREMENTS ----------------------------------------------- Tenant, at Tenant's cost and expense, and irrespective of the cost of compliance, shall comply with all laws, orders and regulations of federal, state, county and municipal authorities relating to the Premises or the use or occupancy thereof, and with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body that shall hereafter perform the function of such Association, except that Tenant shall not be required to make any structural Alterations in order to comply unless such Alterations shall be necessitated by Tenant's Alterations or Trade Fixtures, by Tenant's particular use of the Premises, by Tenant's application for any permit or governmental approval, and/or by the acts, omissions or negligence of Tenant or its servants, employees, contractors, agents, visitors or licensees. 11. PROTECTION OF LENDERS --------------------- 11.1 Subordination. Without the necessity of any additional document, this Lease shall be the subject and subordinate at all times to: (a) all reciprocal easement agreements and all ground leases or underlying leases which may now exist or hereafter be executed affecting the Building, the land on which the Building is located or the Common Area, or any of the foregoing, and (b) the lien of any mortgage or deed of trust which may now exist or hereafter be executed in any amount for which the Building, land on which the Building is located, ground leases or underlying leases, or Landlord's interest or estate in any of said items, is specified as security. Notwithstanding the foregoing, Landlord shall have the right to subordinate or cause to be subordinated to this Lease any of the items referred to in clause (a) or (b) above. Tenant shall execute and deliver, upon demand by Landlord and in the form requested by Landlord, any additional documents evidencing the priority or subordination of this Lease with respect to any such ground leases, underlying leases, reciprocal easement agreements or similar documents or instruments, or with respect to the lien of any such mortgage or deed of trust and containing such matters as lenders customarily and reasonably require in connection with such agreements, including, provisions that the lender will not be liable for: (i) the return of any security deposit unless the lender receives it from Landlord and (ii) any defaults on the part of Landlord occurring prior to the time lender takes possession. Tenant's failure to execute any such document within ten (10) days after written demand therefor shall constitute an event of Tenant's default by Tenant under this Lease. 11.2 Attornment. If Landlord's interest in the Property is acquired by any ground Landlord, beneficiary under a deed of trust, mortgagee, or purchaser at a foreclosure sale, Tenant shall attorn to the transferee of or successor to Landlord's interest in the Property and recognize such transferee or successor as Landlord under this Lease. Tenant waives the protection of any statute or rule of law which gives or purports to give Tenant any right to terminate this Lease or surrender possession of the Property upon the transfer of Landlord's interests. 12. DAMAGE AND DESTRUCTION ---------------------- 12.1 Definition of Terms. For the purposes of this Lease, the term: (a) "Insured Casualty" means damage to or destruction of the Premises from a cause actually insured against, for which the 7. <PAGE> insurance proceeds paid or made available to Landlord are sufficient to rebuild or restore the Premises under then-existing building codes to the condition existing immediately prior to the damage or destruction; and (b) "Uninsured Casualty" means damage to or destruction of the Premises from a cause not actually insured against, or from a cause actually insured against but for which the insurance proceeds paid or made available to Landlord are for any reason insufficient to rebuild or restore the Premises under then-existing building codes to the condition existing immediately prior to the damage or destruction, or from a cause actually insured against but for which the insurance proceeds are not paid or made available to Landlord within twelve (12) months of the event of damage or destruction. 12.2 Insured Casualty. (a) In the event of an Insured Casualty where the extent of damage or destruction is less than twenty-five percent (25%) of the then full replacement cost of the Premises or the Building, Landlord shall rebuild or restore the Premises or the Building substantially to the condition existing immediately prior to the damage or destruction, provided that there exist no governmental codes or regulations that would interfere with Landlord's ability to so rebuild or restore. (b) In the event of an Insured Casualty where the extent of damage or destruction is equal to or greater than twenty-five percent (25%) of the then full replacement cost of the Premises or the Building, Landlord may rebuild or restore the Premises or the Building substantially to the condition existing immediately prior to the damage or destruction, or terminate this Lease. Landlord shall notify Tenant in writing within thirty (30) days from the event of damage or destruction of Landlord's election to either rebuild or restore the Premises or terminate this Lease. 12.3 Uninsured Casualty. In the event of an Uninsured Casualty, Landlord may (i) rebuild or restore the Premises as soon as reasonably possible at Landlord's expense (unless the damage or destruction was caused by a negligent or willful act of Tenant, in which event Tenant shall pay all costs of rebuilding or restoring), in which event this Lease shall continue in full force and effect or (ii) terminate this Lease, in which event Landlord shall give written notice to Tenant within thirty (30) days after the event of damage or destruction of Landlord's election to terminate this Lease as of the date of the event of damage or destruction, and if the damage or destruction was caused by a negligent or willful act of Tenant, Tenant shall be liable therefor to Landlord. Notwithstanding the foregoing, Landlord shall have no right to terminate this Lease with respect to an Uninsured Casualty if the cost of rebuilding or restoring the damage caused thereby is equal to or less than Two Hundred Fifty Thousand Dollars ($250,000). 12.4 Tenant's Election. Notwithstanding anything to the contrary contained in this Article 12, Tenant may elect to terminate this Lease in the event the Premises are damaged or destroyed and, in the reasonable opinion of Landlord's architect or construction consultants, the restoration of the Premises cannot be substantially completed within one hundred eighty (180) days after the event of damage or destruction. Tenant's election shall be made by written notice to Landlord within ten (10) days after Tenant receives from Landlord the estimate of the time needed to complete repair or restoration of the Premises. If Tenant does not deliver said notice within said ten (10) day period, Tenant may not later terminate this Lease even if substantial completion of the rebuilding or restoration occurs subsequent to said one hundred eighty (180) day period, provided that Landlord is proceeding with diligence to rebuild or restore the Premises. If Tenant delivers said notice within said ten (10) day period, this Lease shall terminate as of the date of the event of damage or destruction. 12.5 Continuance of Lease. If Landlord is required or elects to rebuild or restore the Premises pursuant to this Article 12, this Lease shall remain in effect and Tenant shall have no claim against Landlord for compensation for inconvenience or loss business during any period of repair or restoration. 12.6 Damage or Destruction Near End of Lease Term. Notwithstanding anything to the contrary contained in this Article 12, in the event the Premises are damaged or destroyed in whole in part (regardless of the extent of damage) from any cause during the last twelve (12) months of the Lease Term, Landlord may, at Landlord's option, terminate this Lease as of the date of the event of damage or destruction by giving written notice to Tenant of Landlord's election to do so within thirty (30) days after the event of such damage or destruction. For purposes of this Section 12.6, if Tenant has been granted an option to extend or renew the Lease Term pursuant to another provision of this Lease, then the damage or destruction shall be deemed to have occurred during the last twelve (12) months of the Lease Term if 8. <PAGE> Tenant fails to exercise its option to extend or renew within twenty (20) days of the event of damage or destruction. 12.7 Termination of Lease. If the Lease is terminated pursuant to this Article 12, the current Rentals shall be proportionately reduced during the period following the event of damage or destruction until the date on which Tenant surrenders the Premises, based upon the extent to which the damage or destruction interferes with Tenant's business conducted in the Premises, as reasonably determined by Landlord, to the extent such loss is covered as an insured peril by the insurance carried by Landlord, and to the extent the resulting loss of income is covered by rental income or other insurance carried by Landlord. 12.8 Abatement of Rentals. If the Premises are to be rebuilt or restored pursuant to this Article 12, the then current Rentals shall be proportionately reduced during the period of repair or restoration, based upon the extent to which the making of repairs interferes with Tenant's business conducted in the Premises, as reasonably determined by Landlord. In the event Tenant reasonably disputes Landlord's determination regarding Rentals in Section 12.7 above and/or in the preceding sentence, then Tenant shall, within thirty (30) days following written notice to Tenant of such determination by Landlord, have the right to send Landlord written notice objecting to such determination and requesting that Landlord and Tenant determine by arbitration the extent to which Rentals should be proportionately reduced during the period described in Section 12.7 above or the period of repair or restoration, which arbitration shall be carried out pursuant to the rules and procedures of the American Arbitration Association. All costs and expenses of any such arbitration shall be shared equally by Landlord and Tenant. The determination of any such arbitration shall be binding upon Landlord and Tenant. 12.9 Liability for Personal Property. In no event shall Landlord have any liability for, nor shall it be required to repair or restore, any injury or damage to any improvements, alterations or additions to the Premises made by Tenant, trade fixtures, equipment, merchandise, furniture, or any other property installed by Tenant or at the expense of Tenant. If Landlord or Tenant do not elect to terminate this Lease pursuant to this Article 12, Tenant shall be obligated to promptly rebuild or restore the same to the condition existing immediately prior to the damage or destruction. 12.10 Waiver of Civil Code Remedies. Landlord and Tenant acknowledge that the rights and obligations of the parties upon damage or destruction of the Premises are as set forth herein; therefore Tenant hereby expressly waives any rights to terminate this Lease upon damage or destruction of the Premises, except as specifically provided by this Lease, including without limitation any rights pursuant to the provisions of Subdivision 2 of Section 1932 and Subdivision 4 of Section 1933 of the California Civil Code, as amended from time to time, and the provisions of any similar law hereinafter enacted, which provisions relate to the termination of the hiring of a thing upon its substantial damage or destruction. 13. 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 any transfer in lieu thereof, 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 written notice to the other within thirty (30) days after such date; provided, however, a condition to Tenant's right to terminate shall be that Tenant's use of the balance of the Premises is substantially handicapped, impeded or impaired by the taking. If any material part of the building shall be taken, Landlord shall have the right to terminate this Lease by written notice to Tenant within thirty (30) days of the date of 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 the Landlord for the value of any unexpired term of this Lease or otherwise; provided, Landlord shall have no claim to any portion of the award that is specifically allocable to Tenant's relocation expenses or the interruption of or damage to Tenant's business.
