PREMISES Landlord leases to Tenant and Tenant leases from Landlord, upon the terms and conditions hereinafter set forth, those premises (the "Premises") outlined in red on Exhibit B and described in the Basic Lease Information. The Premises shall be all or part of a building (the "Building") and of a project (the "Project"), which may consist of more than one building and additional facilities, as described in the Basic Lease Information. The Building and Project are outlined in blue and green respectively on Exhibit B. Landlord and Tenant acknowledge that physical changes may occur from time to time in the Premises, Building or Project, and that the number of buildings and additional facilities which constitute the Project may change from time to time, which may result in an adjustment in Tenant's Proportionate Share, as defined in the Basic Lease Information, as provided in Paragraph 7.A. 2. POSSESSION AND LEASE COMMENCEMENT A. B. CONSTRUCTION OF IMPROVEMENTS. If this Lease pertains to a Building to be constructed or improvements to be constructed within a Building, the provisions of this Paragraph 2.B. shall apply in lieu of the provisions of Paragraph 2.A. above and the term commencement date ("Term Commencement Date") shall be the earlier of the date on which: (1) Tenant takes possession of some or all of the Premises; or (2) the improvements to be constructed or performed in the Premises by Landlord (if any) shall have been substantially completed in accordance with the plans and specifications, if any, described on Exhibit C and Tenant's taking of possession of the Premises or any part thereof shall constitute Tenant's confirmation of substantial completion for all purposes hereof, whether or not substantial completion of the Building or Project shall have occurred. If for any reason Landlord cannot deliver possession of the Premises to Tenant on the scheduled Term Commencement Date, Landlord shall not be subject to any liability therefor, nor shall Landlord be in default hereunder except as provided in this Paragraph 2.B. nor shall such failure affect the validity of this Lease, and Tenant agrees to accept possession of the Premises at such time as such improvements have been substantially completed, which date shall then be deemed the Term Commencement Date. Tenant shall not be liable for any Rent for any period prior to the Term Commencement Date (but without affecting any obligations of Tenant <PAGE> 4 under any improvement agreement appended to this Lease). In the event of any dispute as to substantial completion of work performed or required to be performed by Landlord, the certificate of Landlord's architect or general contractor shall be conclusive. Substantial completion shall have occurred notwithstanding Tenant's submission of a punchlist to Landlord, which Tenant shall submit, if at all, with fourteen (14) business days after the Term Commencement Date or otherwise in accordance with any improvement agreement appended to this Lease. Upon Landlord's request, Tenant shall promptly execute and return to Landlord a "Start-Up Letter" in which Tenant shall agree, among other things, to acceptance of the Premises and to the determination of the Term Commencement Date, in accordance with the terms of this Lease, but Tenant's failure or refusal to do so shall not negate Tenant's acceptance of the Premises or affect determination of the Term Commencement Date. The Commencement Date, Rent and Tenant's other obligations shall be postponed to the extent Tenant is unable to occupy the Premises because Landlord fails: (i) to substantially complete any improvements to the Premises required to be performed by Landlord under this Lease, or (ii) to deliver possession of the Premises for any other reason, except to the extent that Tenant, it's contractors, agents or employees have caused such failure. Any such delay in the Commencement Date shall not subject Landlord to liability for loss or damage resulting therefrom, and Tenant's sole recourse with respect thereto shall be the postponement of Rent and other obligations. Notwithstanding the foregoing, in the event Landlord's failures described above have caused the delay of the Commencement Date, without Tenant delay or Force Majeure contributing to such delay, and the Commencement Date is delayed for more than sixty (60) days past the date set forth in the Basic Lease Information, then Landlord shall credit to Tenant, for each day of delay after such sixty (60) day period until possession of the Premises is delivered to Tenant, the amount of $1,488.96. For purposes of this Paragraph 2, delays caused by the agents or contractors of a party shall be deemed to be delays caused by that party. 3. TERM The term of this Lease (the "Term") shall commence on the Term Commencement Date and continue in full force and effect for the number of months specified as the Length of Term in the Basic Lease Information or until this Lease is terminated as otherwise provided herein. If the Term Commencement Date is a date other than the first day of the calendar month, the Term shall be the number of months of the Length of Term in addition to the remainder of the calendar month following the Term Commencement Date. 4. USE A. GENERAL. Tenant shall use the Premises for the permitted use specified in the Basic Lease Information ("Permitted Use") and for no other use or purpose. Tenant shall control Tenant's employees, agents, customers, visitors, invitees, licensees, contractors, assignees and subtenants (collectively, "Tenant's Parties") in such a manner that Tenant and Tenant's Parties cumulatively do not exceed the occupant density (the "Occupancy Density") or the parking density (the "Parking Density") specified in the Basic Lease Information at any time. Tenant shall pay the Parking Charge specified in the Basic Lease Information as Additional Rent (as hereinafter defined) hereunder. So long as Tenant is occupying the Premises, Tenant and Tenant's Parties shall have the nonexclusive right to use, in common with other parties occupying the Building or Project, the parking areas, driveways and other common areas of the Building and Project, subject to the terms of this Lease and such rules and regulations as Landlord may from time to time prescribe. Landlord reserves the right, without notice or liability to Tenant, and without the same constituting an actual or constructive eviction, to alter or modify the common areas from time to time, including the location and configuration thereof, and the amenities and facilities which Landlord may determine to provide from time to time, provided, however, that any such changes shall not materially affect or impair Tenant's use of or access to the Premises. B. LIMITATIONS. Tenant shall not permit any odors, smoke, dust, gas, substances, noise or vibrations to emanate from the Premises or from any portion of the common areas as a result of Tenant's or any Tenant's Party's use thereof, nor take any action which would constitute a nuisance or would disturb, obstruct or endanger any other tenants or occupants of the Building or Project or elsewhere, or interfere with their use of their respective premises or common areas. Storage outside the Premises of materials, <PAGE> 5 vehicles or any other items is prohibited. Tenant shall not use or allow the Premises to be used for any immoral, improper or unlawful purpose, nor shall Tenant cause or maintain or permit any nuisance in, on or about the Premises. Tenant shall not commit or suffer the commission of any waste in, on or about the Premises. Tenant shall not allow any sale by auction upon the Premises, or place any loads upon the floors, walls or ceilings which could endanger the structure, or place any harmful substances in the drainage system of the Building or Project. No waste, materials or refuse shall be dumped upon or permitted to remain outside the Premises. Landlord shall not be responsible to Tenant for the non-compliance by any other tenant or occupant of the Building or Project with any of the above-referenced rules or any other terms or provisions of such tenant's or occupant's lease or other contract. C. COMPLIANCE WITH REGULATIONS. By entering the Premises, Tenant accepts the Premises in the condition existing as of the date of such entry. Tenant shall at its sole cost and expense strictly comply with all existing or future applicable municipal, state and federal and other governmental statutes, rules, requirements, regulations, laws and ordinances, including zoning ordinances and regulations, and covenants, easements and restrictions of record governing and relating to the use, occupancy or possession of the Premises, to Tenant's use of the common areas, or to the use, storage, generation or disposal of Hazardous Materials (hereinafter defined) (collectively "Regulations"). Landlord warrants that to Landlord's actual knowledge as of the Commencement Date, the Premises comply with all Regulations, punchlist items excepted. Tenant shall at its sole cost and expense obtain any and all licenses or permits necessary for Tenant's use of the Premises. Tenant shall at its sole cost and expense promptly comply with the requirements of any board of fire underwriters or other similar body now or hereafter constituted. Tenant shall not do or permit anything to be done in, on, under or about the Project or bring or keep anything which will in any way increase the rate of any insurance upon the Premises, Building or Project or upon any contents therein or cause a cancellation of said insurance or otherwise affect said insurance in any manner. Tenant shall indemnify, defend (by counsel reasonably acceptable to Landlord), protect and hold Landlord harmless from and against any loss, cost, expense, damage, attorneys' fees or liability arising out of the failure of Tenant to comply with any Regulation. Landlord shall likewise indemnify, defend (by counsel reasonably acceptable to Tenant), protect and hold Tenant harmless from and against any loss, cost, expense, damage, attorneys' fees or liability arising out of Landlord's breach of warranty that as of the Commencement Date the Premises comply with all applicable regulations. Tenant's obligations pursuant to the foregoing indemnity shall survive the expiration or earlier termination of this Lease. D. HAZARDOUS MATERIALS. As used in this Lease, "Hazardous Materials" shall include, but not be limited to, hazardous, toxic and radioactive materials and those substances defined as "hazardous substances," "hazardous materials," "hazardous wastes," "toxic substances," or other similar designations in any Regulation. Tenant shall not cause, or allow any of Tenant's Parties to cause, any Hazardous Materials to be handled, used, generated, stored, released or disposed of in, on, under or about the Premises, the Building or the Project or surrounding land or environment in violation of any Regulations. Tenant must obtain Landlord's written consent prior to the introduction of any Hazardous Materials onto the Project. Notwithstanding the foregoing, Tenant may handle, store, use and dispose of products containing small quantities of Hazardous Materials for "general office purposes" (such as toner for copiers) to the extent customary and necessary for the Permitted Use of the Premises; provided that Tenant shall always handle, store, use, and dispose of any such Hazardous Materials in a safe and lawful manner and never allow such Hazardous Materials to contaminate the Premises, Building, or Project or surrounding land or environment. Tenant shall immediately notify Landlord in writing of any Hazardous Materials' contamination of any portion of the Project of which Tenant becomes aware, whether or not caused by Tenant. Landlord shall have the right at all reasonable times, upon at least two (2) hours advance notice, and during regular normal business hours and without interfering with Tenant's business operations, to inspect the Premises and to conduct tests and investigations to determine whether Tenant is in compliance with the foregoing provisions, the costs of all such inspections, tests and investigations to be borne by Tenant. Tenant shall indemnify, defend (by counsel reasonably acceptable to Landlord), protect and hold Landlord harmless from and against any and all claims, liabilities, losses, costs, loss of rents, liens, damages, injuries or expenses (including attorneys' and consultants' fees and court costs), demands, causes of action, or judgments directly or indirectly arising out of or related to the use, generation, storage, release, or disposal of Hazardous Materials by Tenant or any of Tenant's Parties in, <PAGE> 6 on, under or about the Premises, the Building or the Project or surrounding land or environment, which indemnity shall include, without limitation, damages for personal or bodily injury, property damage, damage to the environment or natural resources occurring on or off the Premises, losses attributable to diminution in value or adverse effects on marketability, the cost of any investigation, monitoring, government oversight, repair, removal, remediation, restoration, abatement, and disposal, and the preparation of any closure or other required plans, whether such action is required or necessary prior to or following the expiration or earlier termination of this Lease. Landlord shall likewise indemnify, defend (by counsel reasonably acceptable to Tenant), protect and hold Tenant harmless from and against any loss, cost, expense, damage, attorneys' fees or liability arising from or relating to the existence of Hazardous Materials at the Premises as of the Commencement Date and any Hazardous Materials handled, used, generated, stored, released or disposed of in the Premises in violation of any Regulations, by Landlord, it's employees, agents, customers, invitees, licensees, contractors or assignees (collectively "Landlord's Parties). Neither the consent by Landlord to the use, generation, storage, release or disposal of Hazardous Materials nor the strict compliance by Tenant with all laws pertaining to Hazardous Materials shall excuse Tenant from Tenant's obligation of indemnification pursuant to this Paragraph 4.D. Tenant's obligations pursuant to the foregoing indemnity shall survive the expiration or earlier termination of this Lease. 5. RULES AND REGULATIONS Tenant shall faithfully observe and comply with the building rules and regulations attached hereto as Exhibit A and any other rules and regulations and any modifications or additions thereto which Landlord may reasonably from time to time prescribe in writing for the purpose of maintaining the proper care, cleanliness, safety, traffic flow and general order of the Premises or the Building or Project. Tenant shall cause Tenant" Parties to comply with such rules and regulations.

Base Rent for the first full month of the Term shall be paid by Tenant upon Tenant's execution of this Lease. If the obligation for payment of Base Rent commences on a day other than the first day of a month, then Base Rent shall be prorated and the prorated installment shall be paid on the first day of the calendar month next succeeding the Term Commencement Date. The Base Rent payable by Tenant hereunder is subject to adjustment as provided elsewhere in this Lease, as applicable. As used herein, the term "Base Rent" shall mean the Base Rent specified in the Basic Lease Information as it may be so adjusted from time to time. B. ADDITIONAL RENT.

Tenant shall pay the applicable Tenant's Proportionate Share of each such Operating Expenses. <PAGE> 7 Landlord and Tenant acknowledge that if the number of buildings which constitute the Project increases or decreases, or if physical changes are made to the Premises, Building or Project or the configuration of any thereof, Landlord may at its discretion reasonably adjust Tenant's Proportionate Share of the Building or Project to reflect the change. Landlord's determination of Tenant's Proportionate Share of the Building and of the Project shall be conclusive so long as it is reasonably and consistently applied. "Operating Expenses" shall mean all expenses and costs of every kind and nature which Landlord shall pay or become obligated to pay, because of or in connection with the ownership, management, maintenance, repair, preservation, replacement and operation of the Building or Project and its supporting facilities and such additional facilities now and in subsequent years as may be determined by Landlord to be necessary or desirable to the Building and/or Project (as determined in a reasonable manner) other than those expenses and costs which are specifically attributable to Tenant or which are expressly made the financial responsibility of Landlord or specific tenants of the Building or Project pursuant to this Lease. Operating Expenses shall include, but are not limited to, the following: (1) TAXES.

Operating Expenses shall also include any taxes, assessments, reassessments, or other fees or impositions with respect to the development, leasing, management, maintenance, alteration, repair, use or occupancy of the Premises, Building or Project or any portion thereof, including, without limitation, by or for Tenant, and all increases therein or reassessments thereof whether the increases or reassessments result from increased rate and/or valuation (whether upon a transfer of the Building or Project or any portion thereof or any interest therein or for any other reason). Operating Expenses shall not include inheritance or estate taxes imposed upon or assessed against the interest of any person in the Project, or taxes computed upon the basis of the net income of any owners of any interest in the Project. If it shall not be lawful for Tenant to reimburse Landlord for all or any part of such taxes, the monthly rental payable to Landlord under this Lease shall be revised to net Landlord the same net rental after imposition of any such taxes by Landlord as would have been payable to Landlord prior to the payment of any such taxes. (2) INSURANCE.

(San Francisco) or its successor at the time such improvements or capital assets are constructed or acquired, plus two (2) percentage points, or in the absence of such prime rate, then at the U.S. Treasury six-month market note (or bond, if so designated) rate as published by any national financial publication selected by Landlord, plus four (4) percentage points, but in no event more than the maximum rate permitted by law. (c) Payment under or for any easement, license, permit, operating agreement, declaration, restrictive covenant or instrument relating to the Building or Project. (d) All expenses and rental related to services and costs of supplies, materials and equipment used in operating, managing and maintaining the Premises, Building and Project, the equipment therein and the adjacent sidewalks, driveways, parking and service areas, including, without limitation, expenses related to service agreements regarding security, fire and other alarm systems, janitorial services, window cleaning, elevator maintenance, Building exterior maintenance, landscaping and expenses related to the administration, management and operation of the Project, including without limitation salaries, wages and benefits and management office rent.

(g) A management and accounting cost recovery fee equal to five percent (5%) of the sum of the Project's base rents and Operating Expenses (other than such management and accounting fee). If the rentable area of the Building and/or Project is not fully occupied during any fiscal year of the Term as determined by Landlord, an adjustment may be made in Landlord's discretion in computing the Operating Expenses for such year so that Tenant pays an equitable portion of all variable items (e.g., utilities, janitorial services and other component expenses that are affected by variations in occupancy levels) of Operating Expenses, as reasonably determined by Landlord; provided, however, that in no event shall Landlord be entitled to collect in excess of one hundred percent (100%) of the total Operating Expenses from all of the tenants in the Building or Project, as the case may be. Operating Expenses shall not include the cost of providing tenant improvements or other specific costs incurred for the account of, separately billed to and paid by specific tenants of the Building or Project, the initial construction cost of the Building, or debt service on any mortgage or deed of trust recorded with respect to the Project other than pursuant to Paragraph 7.A.(3)(b) above. Notwithstanding anything herein to the contrary, in any instance wherein Landlord, in Landlord's reasonable discretion, deems Tenant to be responsible for any amounts greater than Tenant's Proportionate Share, Landlord shall have the right to allocate costs in any manner Landlord reasonably deems appropriate. <PAGE> 9 The above enumeration of services and facilities shall not be deemed to impose an obligation on Landlord to make available or provide such services or facilities except to the extent if any that Landlord has specifically agreed elsewhere in this Lease to make the same available or provide the same. Without limiting the generality of the foregoing, Tenant acknowledges and agrees that it shall be responsible for providing adequate security for its use of the Premises, the Building and the Project and that Landlord shall have no obligation or liability with respect thereto, except to the extent if any that Landlord has specifically agreed elsewhere in this Lease to provide the same. B. PAYMENT OF ESTIMATED OPERATING EXPENSES. "Estimated Operating Expenses" for any particular year shall mean Landlord's estimate of the Operating Expenses for such fiscal year made with respect to such fiscal year as hereinafter provided. Landlord shall have the right from time to time to revise its fiscal year and interim accounting periods so long as the periods as so revised are reconciled with prior periods in a reasonable manner. During the last month of each fiscal year during the Term, or as soon thereafter as practicable, Landlord shall give Tenant written notice of the Estimated Operating Expenses for the ensuing fiscal year. Tenant shall pay Tenant's Proportionate Share of the Estimated Operating Expenses with installments of Base Rent for the fiscal year to which the Estimated Operating Expenses applies in monthly installments on the first day of each calendar month during such year, in advance. Such payment shall be construed to be Additional Rent for all purposes hereunder. If at any time during the course of the fiscal year, Landlord determines that Operating Expenses are projected to vary from the then Estimated Operating Expenses by more than five percent (5%), Landlord may, by written notice to Tenant, revise the Estimated Operating Expenses for the balance of such fiscal year, and Tenant's monthly installments for the remainder of such year shall be adjusted so that by the end of such fiscal year Tenant has paid to Landlord Tenant's Proportionate Share of the revised Estimated Operating Expenses for such year, such revised installment amounts to be Additional Rent for all purposes hereunder. C. COMPUTATION OF OPERATING EXPENSE ADJUSTMENT. "Operating Expense Adjustment" shall mean the difference between Estimated Operating Expenses and actual Operating Expenses for any fiscal year determined as hereinafter provided. Within one hundred twenty (120) days after the end of each fiscal year, or as soon thereafter as practicable, Landlord shall deliver to Tenant a statement of actual Operating Expenses for the fiscal year just ended, accompanied by a computation of Operating Expense Adjustment. If such statement shows that Tenant's payment based upon Estimated Operating Expenses is less than Tenant's Proportionate Share of Operating Expenses, then Tenant shall pay to Landlord the difference within twenty (20) days after receipt of such statement, such payment to constitute Additional Rent for all purposes hereunder. If such statement shows that Tenant's payments of Estimated Operating Expenses exceed Tenant's Proportionate Share of Operating Expenses, then (provided that Tenant is not in default under this Lease) Landlord shall pay to Tenant the difference within twenty (20) days after the date of delivery of the statement. Should this lease commence or terminate at any time other than the first day of the fiscal year, Tenant's Proportionate Share of the Operating Expense Adjustment shall be prorated based on a month of 30 days and the number of calendar months during such fiscal year that this Lease is in effect. Notwithstanding anything to the contrary contained in Paragraph 7.A or 7.B, Landlord's failure to provide any notices or statements within the time periods specified in those paragraphs shall in no way excuse Tenant from its obligation to pay Tenant's Proportionate Share of Operating Expenses. D. NET LEASE. This shall be a triple net Lease and Base Rent shall be paid to Landlord absolutely net of all costs and expenses, except as specifically provided to the contrary in this Lease. The provisions for payment of Operating Expenses and the Operating Expense Adjustment are intended to pass on to Tenant and reimburse Landlord for all costs and expenses of the nature described in Paragraph 7.A incurred in connection with the ownership, management, maintenance, repair, preservation, replacement and operation of the Building and/or Project and its supporting facilities and such additional facilities now and in subsequent years as may be determined by Landlord to be necessary or desirable to the Building and/or Project. E. TENANT AUDIT. If Tenant shall dispute the amount set forth in any statement provided by Landlord under Paragraph 7.B or 7.C above, Tenant shall have the right, not later than forty-five (45) days following <PAGE> 10 receipt of such statement and upon the condition that Tenant shall first deposit with Landlord the full amount in dispute, to cause Landlord's books and records with respect to Operating Expenses for such fiscal year to be audited by certified public accountants selected by Tenant and subject to Landlord's reasonable right of approval. The Operating Expense Adjustment shall be appropriately adjusted on the basis of such audit. If such audit discloses a liability for a refund in excess of ten percent (10%) of Tenant's Proportionate Share of the Operating Expenses previously reported, the cost of such audit shall be borne by Landlord; otherwise the cost of such audit shall be paid by Tenant. If Tenant shall not request an audit in accordance with the provisions of this Paragraph 7.E within twenty (20) days after receipt of Landlord's statement provided pursuant to Paragraph 7.B or 7.C, such statement shall be final and binding for all purposes hereof. 8. INSURANCE AND INDEMNIFICATION A. LANDLORD'S INSURANCE. All insurance maintained by Landlord shall be for the sole benefit of Landlord and under Landlord's sole control. (1) PROPERTY INSURANCE. Landlord agrees to maintain property insurance insuring the Building against damage or destruction due to risk including fire, vandalism, and malicious mischief in an amount not less than the replacement cost thereof, in the form and with deductibles and endorsements as selected by Landlord.

Such coverage shall have a minimum combined single limit of liability of at least Two Million Dollars ($2,000,000.00), and a minimum general aggregate limit of Two Million Dollars ($2,000,000.00), with an "Additional Insured - Managers or Lessors of Premises Endorsement."

Such coverage shall also contain endorsements including employees as additional insureds if not covered by Tenant's Commercial General Liability Insurance. All such insurance shall provide for the severability of interests of insureds; and shall be written on an "occurrence" basis, which shall afford coverage for all claims based on acts, omissions, injury and damage, which occurred or arose (or the onset of which occurred or arose) in whole or in part during the policy period.

If at any time during the Term the amount or coverage of insurance which Tenant is required to carry under this Paragraph 8.B. is, in Landlord's reasonable judgment, materially less than the amount or type of insurance coverage typically carried by owners or tenants of properties located in the general area in which the Premises are located which are similar to and operated for similar purposes as the Premises or if Tenant's use of the Premises should change with or without Landlord's consent, Landlord shall have the right to require Tenant to increase the amount or change the types of insurance coverage required under this Paragraph 8.B. All insurance policies required to be carried by Tenant under this Lease shall be written companies rated A X or better in "Best's Insurance Guide" and authorized to do business in the State of California. In any event deductible amounts under all insurance policies required to be carried by Tenant under this Lease shall not exceed Five Thousand Dollars ($5,000.00) per occurrence. Tenant shall deliver to Landlord on or before the Term Commencement Date, and thereafter at least thirty (30) days before the expiration dates of the expired policies, certified copies of Tenant's insurance policies, or a certificate evidencing the same issued by the insurer thereunder; and, if Tenant shall fail to procure such insurance, or to deliver such policies or certificates, Landlord may, at Landlord's option and in addition to Landlord's other remedies in the event of a default by Tenant hereunder, procure the same for the account of Tenant, and cost thereof shall be paid to Landlord as Additional Rent. C. INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably acceptable to Landlord, protect and hold Landlord harmless from and against any and all claims, liabilities, loses, costs, lost of rents, liens, damages, injuries or expenses, including reasonable attorneys' and consultants' fees and court costs, demands, causes of action, or judgments, directly or indirectly arising out of or related to: (1) claims of injury to or death of persons or damage to property occurring or resulting directly or indirectly from the use or occupancy of the Premises, Building or Project by Tenant or Tenant's Parties, or from activities or failures to act of Tenant or Tenant's Parties; (2) claims arising from work or labor performed, or for materials or supplies furnished to or at the request or for the account of Tenant in connection with performance of any work done for the account of Tenant within the Premises or Project; (3) claims arising from any breach or default on the part of Tenant in the performance of any covenant contained in this Lease; and (4) claims arising from the negligence or intentional acts or omissions of Tenant or Tenant's Parties. The foregoing indemnity by Tenant shall not be applicable to claims to the extent arising from the gross negligence or willful misconduct of Landlord. Landlord shall not be liable to Tenant and Tenant hereby waives all claims against Landlord for any injury or damage to any person or property in or about the Premises, Building or Project by or from any cause whatsoever (other than Landlord's gross negligence or willful misconduct) and, without limiting the generality of the foregoing, whether caused by water leakage of any character form the roof, walls, basement or other portion of the Premises, Building <PAGE> 12 or Project, or caused by gas, fire, oil or electricity in, on or about the Premises, Building or Project. The provisions of this Paragraph shall survive the expiration or earlier termination of this Lease. 9. WAIVER OF SUBROGATION To the extent permitted by law and without affecting the coverage provided by insurance to be maintained hereunder or any other rights or remedies, Landlord and Tenant each waive any right to recover against the other for: (a) damages for injury to or death of persons; (b) damages to property, including personal property; (c) damages to the Premises or any part thereof; and (d) claims arising by reason of the foregoing due to hazards covered by insurance maintained or required to be maintained pursuant to this Lease to the extent of proceeds recovered therefrom, or proceeds which would have been recoverable therefrom in the case of the failure of any party to maintain any insurance coverage required to be maintained by such party pursuant to this Lease. This provision is intended to waive fully, any rights and/or claims arising by reason of the foregoing, but only to the extent that any of the foregoing damages and/or claims referred to above are covered or would be covered, and only to the extent of such coverage, by insurance actually carried or required to be maintained pursuant to this Lease by either Landlord or Tenant. This provision is also intended to waive fully, and for the benefit of each party, any rights and/or claims which might give rise to a right of subrogation on any insurance carrier. Subject to all qualifications of this Paragraph 9, Landlord waives its rights as specified in this Paragraph 9 with respect to any subtenant that it has approved pursuant to Paragraph 21 but only in exchange for the written waiver of such rights to be given by such subtenant to Landlord upon such subtenant taking possession of the Premises or a portion thereof. Each party shall cause each insurance policy obtained by it to provide that the insurance company waives all right of recovery by way of subrogation against either party in connection with any damage covered by any policy. 10. LANDLORD'S REPAIRS AND MAINTENANCE Landlord shall at Landlord's sole expense maintain in good repair, reasonable wear and tear excepted, the structural soundness of the roof, foundations, and exterior walls of the Building. The term "exterior walls" as used herein shall not include doors, special store fronts or office entries. Any damage caused by or repairs necessitated by any negligence or act of Tenant or Tenant's Parties may be repaired by Landlord at Landlord's option and Tenant's expense. Tenant shall immediately give Landlord written notice of any defect or need of repairs in such components of the Building for which Landlord is responsible, after which Landlord shall have a reasonable opportunity and the right to enter the Premises at all reasonable times upon at least two (2) hours advance notice, and during regular business hours and without interfering with Tenant's business operations to repair same. Landlord's liability with respect to any defects, repairs, or maintenance for which Landlord is responsible under any of the provisions of this Lease shall be limited to the cost of such repairs or maintenance, and there shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant's business arising from the making of repairs, alterations or improvements in or to any portion of the Premises, the Building or the Project or to fixtures, appurtenances or equipment in the Building, except as provided in Paragraph 24 as of the Commencement Date, the Premises are in good order, condition and repair. By taking possession of the Premises, Tenant accepts them "as is," as being in good order, condition and repair and the condition in which Landlord is obligated to deliver them and suitable for the Permitted Use and Tenant's intended operations in the Premises. 11. TENANT'S REPAIRS AND MAINTENANCE Tenant shall at all times during the Term at Tenant's expense maintain all parts of the Premises and such portions of the Building as are within the exclusive control of Tenant in a first-class, good, clean and secure condition and promptly make all necessary repairs and replacements, as determined by Landlord, with materials and workmanship of the same character, kind and quality as the original. Notwithstanding anything to the contrary contained herein, Tenant shall, at its expense, promptly repair any damage to the Premises or the Building or Project resulting from or caused by any negligence or act of Tenant or Tenant's Parties. <PAGE> 13 12. ALTERATIONS A. Tenant shall not make, or allow to be made, any alterations, physical additions, improvements or partitions, including without limitation the attachment of any fixtures or equipment, in, about or to the Premises ("ALTERATIONS") without obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld with respect to proposed Alterations which: (a) comply with all applicable Regulations; (b) are, in Landlord's opinion, compatible with the Building or the Project and its mechanical, plumbing, electrical, heating/ventilation/air conditioning systems, and will not cause the Building or Project or such systems to be required to be modified to comply with any Regulations (including, without limitation, the Americans With Disabilities Act); and (c) will not interfere with the use and occupancy of any other portion of the Building or Project by any other tenant or its invitees. Specifically, but without limiting the generality of the foregoing, Landlord shall have the right of written consent for all plans and specifications for the proposed Alterations, construction means and methods, all appropriate permits and licenses, any contractor or subcontractor to be employed on the work of Alterations, and the time for performance of such work, and may impose rules and regulations for contractors and subcontractors performing such work. Tenant shall also supply to Landlord any documents and information reasonably requested by Landlord in connection with Landlord's consideration of a request for approval hereunder. Tenant shall cause all Alterations to be accomplished in a first-class, good and workmanlike manner, and to comply with all applicable Regulations and Paragraph 27 hereof. Tenant shall at Tenant's sole expense, perform any additional work required under applicable Regulations due to the Alterations hereunder. No review or consent by Landlord of or to any proposed Alteration or additional work shall constitute a waiver of Tenant's obligations under this Paragraph 12, nor constitute any warranty or representation that the same complies with all applicable Regulations, for which Tenant shall at all times be solely responsible. Tenant shall reimburse Landlord for all costs which Landlord may reasonably incur in connection with granting approval to Tenant for any such Alterations, including any costs or expenses which Landlord may incur in electing to have outside architects and engineers review said plans and specifications, and shall pay Landlord an administration fee of ten percent (10%) of the cost of the Alterations as Additional Rent hereunder. All such Alterations shall remain the property of Tenant until the expiration or earlier termination of this Lease, at which time they shall be and become the property of Landlord; provided, however, that Landlord may, at Landlord's option, require that Tenant, at Tenant's expense, remove any or all Alterations made by Tenant and restore the Premises by the expiration or earlier termination of this Lease, to their condition existing prior to the construction of any such Alterations. Notwithstanding the foregoing, unless Landlord notifies Tenant of its desire to have the alterations removed at the time of it's approval of the project, then Tenant may deem Landlord's right to require removal to have been waived. All such removals and restoration shall be accomplished in a first-class and good and workmanlike manner so as not to cause damage to the Premises or Project whatsoever. If Tenant fails to remove such Alterations or Tenant's trade fixtures or furniture or other personal property, Landlord may keep and use them or remove any of them and cause them to be stored or sold in accordance with applicable law, at Tenant's sole expense. In addition to and wholly apart from Tenant's obligation to pay Tenant's Proportionate Share of Operating Expenses, Tenant shall be responsible for and shall pay prior to delinquency any taxes or governmental service fees, possessory interest taxes, fees or charges in lieu of any such taxes, capital levies, or other charges imposed upon, levied with respect to or assessed against its fixtures or personal property, on the value of Alterations within the Premises, and on Tenant's interest pursuant to this Leas, or any increase in any of the foregoing based on such Alterations. To the extent that any such taxes are not separately assessed or billed to Tenant, Tenant shall pay the amount thereof as invoiced to Tenant by Landlord. Notwithstanding the foregoing, at Landlord's option (but without obligation), all or any portion of the Alterations shall be performed by Landlord for Tenant's account and Tenant shall pay Landlord's estimate of the cost thereof (including a reasonable charge for Landlord's overhead and profit) prior to commencement of the work. In addition, at Landlord's election and notwithstanding the foregoing, however, Tenant shall pay to Landlord the cost of removing any such Alterations and restoring the Premises to their original condition such cost to include a reasonable charge for Landlord's overhead and profit as provided above, and such amount may be deducted from the Security Deposit or any other sums or amounts held by Landlord under this Lease. <PAGE> 14 B. In compliance with Paragraph 27 hereof, at least ten (10) business days before beginning construction of any Alteration, Tenant shall give Landlord written notice of the expected commencement date of that construction to permit Landlord to post and record a notice of non-responsibility. Upon substantial completion of construction, if the law so provides, Tenant shall cause a timely notice of completion to be recorded in the office of the recorder of the county in which the Building is located. 13. SIGNS Tenant shall not place, install, affix, paint or maintain any signs, notices, graphics or banners whatsoever or any window decor which is visible in or from the public view or corridors, the common areas or the exterior of the Premises or the Building, in or on any exterior window or window fronting upon any common areas or service area without Landlord's prior written approval which Landlord shall have the right to withhold in its absolute discretion; provided that Tenant's name shall be included in any Building-standard door and directory signage, if any, in accordance with Landlord's Building signage program, including without limitation, payment by Tenant of any fee charged by Landlord for maintaining such signage, which fee shall constitute Additional Rent hereunder. Any installation of signs, notices, graphics or banners on or about the Premises or Project approved by Landlord shall be subject to any Regulations and to any other requirements imposed by Landlord. Tenant shall remove all such signs or graphics by the expiration or any earlier termination of this Lease. Such installations and removals shall be made in such manner as to avoid injury to or defacement of the Premises, Building or Project and any other improvements contained therein, and Tenant shall repair any injury or defacement including without limitation discoloration caused by such installation or removal. 14. INSPECTION/POSTING NOTICES Upon at least twenty-four (24) hours advance notice, and during regular business hours and without interfering with Tenant's business operations except in emergencies where no such notice shall be required, Landlord and Landlord's agents and representatives, shall have the right to enter the Premises to inspect the same, to clean, to perform such work as may be permitted or required hereunder, to make repairs, improvements or alterations to the Premises, Building or Project or to other tenant spaces therein, to deal with emergencies, to post such notices as may be permitted or required by law to prevent the perfection of liens against Landlord's interest in the Project, or to exhibit the Premises to prospective tenants, purchasers, encumbrancers or to others, or for any other purpose as Landlord may deem necessary or desirable; provided, however, that Landlord shall use reasonable efforts not to unreasonably interfere with Tenant's business operations. Tenant shall not be entitled to any abatement of Rent by reason of the exercise of any such right of entry. Tenant waives any claim for damages for any injury or inconvenience to or interference with Tenant's business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby. Landlord shall at all times have and retain a key with which to unlock all of the doors in, upon and about the Premises, excluding Tenant's vaults and safes or special security areas (designated in advance), and Landlord shall have the right to use any and all means which Landlord may deem necessary or proper to open said doors in an emergency, in order to obtain entry to any portion of the Premises, and any entry to the Premises or portions thereof obtained by Landlord by any of said means, or otherwise, shall not be construed 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 portions thereof. At any time within six (6) months prior to the expiration of the Term or following any earlier termination of this Lease or agreement to terminate this Lease, Landlord shall have the right to erect on the Premises, Building and/or Project a suitable sign indicating that the Premises are available for lease. 15. SERVICES AND UTILITIES A. Provided Tenant shall not be in default hereunder, and subject to the provisions elsewhere herein contained and to the rules and regulations of the Building, Landlord shall furnish to the Premises during ordinary business hours of generally recognized business days, to be reasonably determined by Landlord (but exclusive in any event, of Saturdays, Sundays and legal holidays), water for lavatory and drinking purposes and electricity, heat and air conditioning as usually furnished or supplied for use of the <PAGE> 15 Premises for reasonable and normal office use as of the date Tenant takes possession of the Premises as determined by Landlord (but not including above-standard or continuous cooling for excessive heat-generating machines, excess lighting or equipment), janitorial services during the times and in the manner that such services are, in Landlord's judgment, customarily furnished in comparable office buildings in the immediate market area, and elevator service, which shall mean service either by nonattended automatic elevators with attendants, or both, at the option of Landlord. Tenant acknowledges that Tenant has inspected and accepts the water, electricity, heat and air conditioning and other utilities and services being supplied or furnished to the Premises as of the date Tenant takes possession of the Premises, as being sufficient for use of the Premises for reasonable and normal office use in their present condition, "as is," and suitable for the Permitted Use, and for Tenant's intended operations in the Premises. Provided that Tenant is not in default under the Lease, Landlord shall provide additional or after-hours electricity, heating or air conditioning, but if Landlord provides such services at Tenant's request, Tenant shall pay to Landlord a reasonable charge for such services as determined by Landlord. Tenant agrees to keep and cause to be kept closed all window covering when necessary because of the sun's position, and Tenant also agrees at all times to cooperate fully with Landlord and to abide all of the regulations and requirements which Landlord may prescribe for the proper functioning and protection of electrical, heating, ventilating and air conditioning systems. Wherever heat-generating machines, excess lighting or equipment are used in the Premises which affect the temperature otherwise maintained by the air conditioning system, Landlord reserves the right to install supplementary air conditioning units in the Premises and the cost thereof, including the cost of installation and the cost of operation and maintenance thereof, shall be paid by Tenant to Landlord upon demand by Landlord. B. Tenant shall not without reasonable written consent of Landlord use an apparatus, equipment or device in the Premises, including, without limitation, computers, electronic data processing machines, copying machines, and other machines, using excess lighting or using electrical current, water, or any other resource in excess of or which will in any way increase the amount of electricity, water, or any other resource being furnished or supplied for the use of the Premises for reasonable and normal office use, in each case as of the date Tenant takes possession of the Premises as determined by Landlord, or which will require additions or alterations to or interfere with the Building power distribution systems; nor connect with electric current, except through existing electrical outlets in the Premises or water pipes, any apparatus, equipment or device for the purpose of using electrical current, water, or any other resource,. If Tenant shall require water or electric current or any other resource in excess of that being furnished or supplied for the use of the Premises as of the date Tenant takes possession of the Premises as determined by Landlord, Tenant shall first procure the written consent of Landlord which Landlord may reasonably refuse, to the use thereof, and Landlord may cause a special meter to be installed in the Premises so as to measure the amount of water, electric current or other resource consumed for any such other use. Tenant shall pay directly to Landlord as an addition to and separate from payment of Operating Expenses the cost of all such additional resources, energy, utility service and meters (and of installation, maintenance and repair thereof and of any additional circuits or other equipment necessary to furnish such additional resources, energy, utility or service). Landlord may add to the separate metered charge a recovery of additional expense incurred in keeping account of the excess water, electric current or other resource so consumed. Landlord shall not be liable for any damages directly or indirectly resulting from nor shall the Rent or any monies owed Landlord under this Lease herein reserved by abated by reason of: (a) the installation, use or interruption of use of any equipment used in connection with the furnishing of any such utilities or services, or any change in the character or means of supplying or providing any such utilities or services or any supplier thereof; (b) the failure to furnish or delay in furnishing any such utilities or services when such failure or delay is caused by acts of God or the elements, labor disturbances of any character, or any other accidents or other conditions beyond the reasonable control of Landlord or because of any interruption of service due to Tenant's use of water, electric current or other resource in excess of that being supplied or furnished for the use of the Premises as of the date Tenant takes possession of the Premises; (c) the inadequacy, limitation, curtailment, rationing or restriction on use of water, electricity, gas or any other form of energy or any other service or utility whatsoever serving the Premises or Project, whether by Regulation or otherwise; or (d) the partial or total unavailability of any such utilities or services to the Premises or the Building, whether by Regulation or otherwise; nor shall any such occurrence constitute an actual or constructive eviction of <PAGE> 16 Tenant. Landlord shall further have no obligation to protect or preserve any apparatus, equipment or device installed by Tenant in the Premises, including without limitation by providing additional or after-hours heating or air conditioning. Landlord shall be entitled to cooperate voluntarily and in reasonable manner with the efforts of national, state or local governmental agencies or utility suppliers in reducing energy or other resource consumption. The obligation to make services available hereunder shall be subject to the limitations of any such voluntary, reasonable program. In addition, Landlord reserves the right to change the supplier or provider of any such utility or service from time to time. Tenant shall have not right to contract with or otherwise obtain any electrical or other such service for or with respect to the Premises or Tenant's operations therein from any supplier of any such service. Tenant shall cooperate with Landlord and any supplier or provider of such services designated by Landlord from time to time to facilitate the delivery of such services to Tenant at the Premises and to the Building and Project, including without limitation allowing Landlord and Landlord's suppliers or providers, and their respective agents and contractors, reasonable access to the Premises for the purpose of installing, maintaining, repairing, replacing or upgrading such service or any equipment or machinery associated therewith. C. Tenant shall pay, upon demand, for all utilities furnished to the Premises, or if not separately billed to or metered to Tenant, Tenant's Proportionate Share of all charges jointly serving the Project in accordance with Paragraph 7. All sums payable under this Paragraph 15 shall constitute Additional Rent hereunder. 16. SUBORDINATION Without the necessity of any additional document being executed by Tenant for the purpose of effecting a subordination, the Lease shall be and is hereby declared to be subject and subordinate at all times to: (a) all ground leases or underlying leases which may now exist or hereafter be executed affecting the Premises and/or the land upon which the Premises and Project are situated, or both; and (b) any mortgage or deed of trust which may now exist or be placed upon the Building, the Project and/or the land upon which the Premises or the Project are situated, or said ground leases or underlying leases, or Landlord's interest or estate in any of said items which is specified as security, provided, however, that any such lender, mortgagee, beneficiary or lessor execute an agreement to recognize the Lease and not disturb Tenant for so long as Tenant has not defaulted under this Lease. Notwithstanding the foregoing, Landlord shall have the right to subordinate or cause to be subordinated any such ground leases or underlying leases or any such liens to this Lease. If any ground lease or underlying lease terminates for any reason or any mortgage or deed of trust is foreclosed or a conveyance in lieu of foreclosure is made for any reason, Tenant shall, notwithstanding any subordination, attorn to and become the Tenant of the successor in interest to Landlord provided that Tenant shall not be disturbed in its possession under this Lease by such successor in interest so long as Tenant is not in default under this Lease. Within ten (10) business days after request by Landlord, Tenant shall execute and deliver any additional documents evidencing Tenant's attornment or the subordination of this Lease with respect to any such ground leases or underlying leases or any such mortgage or deed of trust, in the form requested by Landlord or by any ground landlord, mortgagee, or beneficiary under a deed of trust, subject to such nondisturbance requirement. If requested in writing by Tenant, Landlord shall use commercially reasonable efforts to obtain a subordination, nondisturbance and attornment agreement for the benefit of Tenant reflecting the foregoing from any ground landlord, mortgagee or beneficiary, at Tenant's expense, subject to such other terms and conditions as the ground landlord, mortgagee or beneficiary may require. 17. FINANCIAL STATEMENTS At the request of Landlord from time to time, Tenant shall provide to Landlord Tenant's and any guarantor's current financial statements or other information discussing financial worth of Tenant and any guarantor, which Landlord shall use solely for purposes of this Lease and in connection with the ownership, management, financing and disposition of the Project. Landlord shall insure that all information remains confidential. <PAGE> 17 18. ESTOPPEL CERTIFICATE Tenant agrees from time to time, within ten (10) days after request of Landlord, to deliver to Landlord, or Landlord's designee, an estoppel certificate stating that this Lease is in full force and effect, that this Lease has not been modified (or stating all modifications, written or oral, to this Lease), the date to which Rent has been paid, the unexpired portion of this Lease, that there are no current defaults by Landlord or Tenant under this Lease (or specifying any such defaults), that the leasehold estate granted by this Lease is the sole interest of Tenant in the Premises and/or the land at which the Premises are situated, and such other matters pertaining to this Lease as may be reasonably requested by Landlord or any mortgagee, beneficiary, purchaser or prospective purchaser of the Building or Project or any interest therein. Failure by Tenant to execute and deliver such certificate shall constitute an acceptance of the Premises and acknowledgement by Tenant that the statements included are true and correct without exception. Tenant agrees that if Tenant fails to execute and deliver such certificate within such ten (10) day period, Landlord may execute and deliver such certificate on Tenant's behalf that such certificate shall be binding on Tenant. Landlord and Tenant intend that any statement delivered pursuant to this Paragraph may be relied upon by any mortgagee, beneficiary, purchaser or prospective purchaser of the Building or Project or any interest therein. The parties agree that Tenant's obligation to furnish such estoppel certificates in a timely fashion is a material inducement for Landlord's execution of the Lease, and shall be an event of default (without any cure period that might be provided under Paragraph 26.A(3) of this Lease) if Tenant fails to fully comply or makes any material misstatement in any such certificate. 19. SECURITY DEPOSIT Tenant agrees to deposit with Landlord upon execution of this Lease, a security deposit as stated in the Basic Lease Information (the "Security Deposit"), which sum shall be held and owned by Landlord, without obligation to pay interest, as security for the performance of Tenant's covenants and obligations under this Lease. The Security Deposit is not an advance rental deposit or a measure of damages incurred by Landlord in case of Tenant's default. Upon the occurrence of any event of default by Tenant, Landlord may from time to time, without prejudice to any other remedy provided herein or by law, use such fund as a credit to the extent necessary to credit against any arrears of Rent or other payments due to Landlord hereunder, and any other damage, injury, expense or liability caused by such event of default, and Tenant shall pay to Landlord, on demand, the amount so applied in order to restore the Security Deposit to its original amount. Although the Security Deposit shall be deemed the property of Landlord, any remaining balance of such deposit shall be returned by Landlord to Tenant within thirty (30) days from the Lease Termination Date after all of Tenant's obligations under this Lease have been fulfilled, reduced by such amounts as may be reasonably required by Landlord to remedy defaults on the part of Tenant in the payment of Rent or other obligations of Tenant under this Lease, to repair damage to the Premises, Building or Project caused by Tenant or any Tenant's Parties and to clean the Premises. Landlord may use and commingle the Security Deposit with other funds of Landlord. The provisions of Addendum #3 of this Lease are added to this Paragraph 19. 20. LIMITATION OF TENANT'S REMEDIES The obligations and liability of Landlord to Tenant for any default by Landlord under the terms of this Lease are not personal obligations of Landlord or of the individual or other partners of Landlord or its or their partners, directors, officers, or shareholders, and Tenant agrees to look solely to Landlord's interest in the Project and the revenues and proceeds thereof for the recovery of any amount from Landlord, and shall not look to other assets of Landlord nor seek recourse against the assets of the individual or other partners of Landlord or its or their partners, directors, officers or shareholders. Any lien obtained to enforce any such judgment and any levy of execution thereon shall be subject and subordinate to any lien, mortgage or deed of trust on the Project. Under no circumstances shall Tenant have the right, to offset against or recoup Rent or other payments due and to become due to Landlord hereunder except as expressly provided in Paragraph 23.B. below, which Rent and other payments shall be absolutely due and payable hereunder in accordance with the terms hereof. <PAGE> 18 21. ASSIGNMENT AND SUBLETTING A. (1) GENERAL. This Lease has been negotiated to be and is granted as an accommodation to Tenant. Accordingly, this Lease is personal to Tenant, and Tenant's rights granted hereunder do not include the right to assign this Lease or sublease the Premises, or to receive any excess, either in installments or lump sum, over the Rent which is expressly reserved by Landlord as hereinafter provided, except as otherwise expressly hereinafter provided. Except as provided herein, Tenant shall not assign or pledge this Lease or sublet the Premises or any part thereof, whether voluntarily or by operation of law, or permit the use or occupancy of the Premises or any part thereof by anyone other than Tenant, or suffer or permit any such assignment, pledge, subleasing or occupancy, without Landlord's prior written consent which shall not be unreasonably withheld except as provided herein. If Tenant desires to assign this Least or sublet any or all of the Premises, Tenant shall give Landlord written notice (the "Transfer Notice") at least sixty (60) days prior to the anticipated effective date of the proposed assignment or sublease, which shall contain all of the information reasonably requested by Landlord to address Landlord's decision criteria specified hereinafter. Landlord shall then have a period of twenty (20) days following receipt of the Transfer Notice to notify Tenant in writing that Landlord elects either: (i) to terminate this Lease as to the space so affected as of the date so requested by Tenant; or (ii) to consent to the proposed assignment or sublease, subject, however, to Landlord's prior written consent of the proposed assignee or subtenant and of any related documents or agreements associated with the assignment or sublease. If Landlord should fail to notify Tenant in writing of such election within said period, Landlord shall be deemed to have waived option (i) above, but written consent by Landlord of the proposed assignee or subtenant shall still be required. If Landlord does not exercise option (i) above, Landlord's consent to a proposed assignment or sublease shall not be unreasonably withheld. Consent to any assignment or subletting shall not constitute consent to any subsequent transaction to which this Paragraph 21 applies. Notwithstanding the foregoing, Landlord shall not have the right to terminate this Lease following receipt of a Transfer Notice which relates to Tenant's proposed subleasing of not more than 35% of the Premises for a term less than the remaining term of this Lease. (2) CONDITIONS OF LANDLORD'S CONSENT. Without limiting the other instances in which it may be reasonable for Landlord to withhold Landlord's consent to an assignment or subletting, Landlord and Tenant acknowledge that it shall be reasonable for Landlord to withhold Landlord's consent in the following instances: if the proposed assignee does not agree to be bound by and assume the obligations of Tenant under this Lease in form and substance satisfactory to Landlord; the use of the Premises by such proposed assignee or subtenant would not be a Permitted Use or would violate any exclusivity or other arrangement which Landlord has with any other tenant or occupant or any Regulation or would increase the Occupancy Density or Parking Density of the Building or Project, or would otherwise result in an undesirable tenant mix for the Project as determined by Landlord; the proposed assignee or subtenant is not of sound financial condition as determined by Landlord in Landlord's reasonable discretion; the proposed assignee or subtenant is a governmental agency; the proposed assignee or subtenant does not have a good reputation as a tenant of property or a good business reputation; the proposed assignee or subtenant is a person with whom Landlord is negotiating to lease space in the Project or is a present tenant of the Project; the assignment or subletting would entail any Alterations which would lessen the value of the leasehold improvements in the Premises or use of any Hazardous Materials or other noxious use or use which may disturb other tenants of the Project; or Tenant is in default of any obligation of Tenant under this Lease, or Tenant has defaulted under this Lease on three (3) or more occasions during any twelve (12) months preceding the date that Tenant shall request consent. Failure by or refusal of Landlord to consent to a proposed assignee or subtenant shall not cause a termination of this Lease. Upon a termination under Paragraph 21.A.(1)(i), Landlord may lease the Premises to any party, including parties with whom Tenant has negotiated an assignment or sublease, without incurring any liability to Tenant. At the option of Landlord, a surrender and termination of this Lease shall operate as an assignment to Landlord of some or all subleases or subtenancies. Landlord shall exercise this option by giving notice of that assignment to such subtenants on or before the effective date of the surrender and <PAGE> 19 termination. In connection with each request for assignment or subletting, Tenant shall pay to Landlord Landlord's standard fee for approving such requests, as well as all costs incurred by Landlord or any mortgagee or ground lessor in approving each such request and effecting any such transfer, including, without limitation, reasonable attorneys' fees. B. BONUS RENT. Any Rent or other consideration realized by Tenant under any such sublease or assignment in excess of the Rent payable hereunder, after amortization of a reasonable brokerage commission incurred by Tenant, shall be divided and paid, ten percent (10%) to Tenant, ninety percent (90)%) to Landlord. In any subletting or assignment undertaken by Tenant, Tenant shall diligently seek to obtain the maximum rental amount available in the marketplace for comparable space available for primary leasing. C. CORPORATION. If Tenant is a corporation, a transfer of corporate shares by sale, assignment, bequest, inheritance, operation of law or other disposition (including such a transfer to or by a receiver or trustee in federal or state bankruptcy, insolvency or other proceedings) resulting in a change in the present control of such corporation or any of its parent corporations by the person or persons owning a majority of said corporate shares, shall not constitute an assignment for purposes of this Lease. A transfer of controlling interest in the Tenant by way of merger, consolidation or sale of assets shall not constitute an assignment for purposes of this Lease. D. UNINCORPORATED ENTITY. If Tenant is a partnership, joint venture, unincorporated limited liability company or other unincorporated business form, a transfer of the interest of persons, firms or entities responsible for managerial control of Tenant by sale, assignment, bequest, inheritance, operation of law or other disposition, so as to result in a change in the present control of said entity and/or of the underlying beneficial interests of said entity and/or a change in the identity of the persons responsible for the general credit obligations of said entity shall constitute an assignment for all purposes of this Lease. E. LIABILITY. No assignment or subletting by Tenant, permitted or otherwise, shall relieve Tenant of any obligation under this Lease or alter the primary liability of the Tenant named herein for the payment of Rent or for the performance of any other obligations to be performed by Tenant, including obligations contained in Paragraph 25 with respect to any assignee or subtenant. Landlord may collect rent or other amounts or any portion thereof from any assignee, subtenant, or other occupant of the Premises, permitted or otherwise, and apply the net rent collected to the Rent payable hereunder, but no such collection shall be deemed to be a waiver of this Paragraph 21, or the acceptance of the assignee, subtenant or occupant as tenant, or a release of Tenant from the further performance by Tenant of the obligations of Tenant under this Lease. Any assignment or subletting which conflicts with the provisions hereof shall be void. 22. AUTHORITY Landlord represents and warrants that it has full right and authority to enter into this Lease and to perform all of Landlord's obligations hereunder and that all persons signing this Lease on its behalf are authorized to do so. Tenant and the person or persons, if any, signing on behalf of Tenant, jointly and severally represent and warrant that Tenant has full right and authority to enter into this Lease, and to perform all of Tenant's obligations hereunder, and that all persons signing this Lease on its behalf are authorized to do so. 23. CONDEMNATION A. CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial part of the Premises should be taken or condemned for any public use under any Regulation, or by right of eminent domain, or by private purchase in lieu thereof, and the taking would prevent or materially interfere with the Permitted Use of the Premises, either party shall have the right to terminate this Lease at its option. If any material portion of the Building or Project is taken or condemned for any public use under any Regulation, or by right of eminent domain, or by private purchase in lieu thereof, Landlord may terminate this Lease at its <PAGE> 20 option. In either of such events, the Rent shall be abated during the unexpired portion of this Lease, effective when the physical taking of said Premises shall have occurred. B. CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project of which the Premises are a part should be taken or condemnation for any public use under any Regulation, or by right of eminent domain, or by private purchase in lieu thereof, and the taking prevents or materially interferes with the Permitted Use of the Premises, and this Lease is not terminated as provided in Paragraph 23.A. above, the Rent payable hereunder during the unexpired portion of the Lease shall be reduced, beginning on the date when the physical taking shall have occurred, to such amount as may be fair and reasonable under all of the circumstances, but only after giving Landlord' credit for all sums received or to be received by Tenant by the condemning authority. Notwithstanding anything to the contrary contained in this Paragraph, if the temporary use or occupancy of any part of the Premises shall be taken or appropriated under power of eminent domain during the Term, this Lease shall be and remain unaffected by such taking or appropriation and Tenant shall continue to pay in full all Rent payable hereunder by Tenant during the Term; in the event of any such temporary appropriation or taking, Tenant shall be entitled to receive that portion of any award which represents compensation for the use of or occupancy of the Premises during the Term, and Landlord shall be entitled to receive that portion of any award which represents the cost of restoration of the Premises and the use and occupancy of the Premises. C. AWARD. In the event of a permanent taking, Landlord shall be entitled to (and Tenant shall assign to Landlord) any and all payment, income, rent, award or any interest therein whatsoever which may be paid or made in connection with such taking or conveyance and Tenant shall have no claim against Landlord or otherwise for any sums paid by virtue of such proceedings, whether or not attributable to the value of any unexpired portion of this Lease, except as expressly provided in this Lease. Notwithstanding the foregoing, any compensation specifically and separately awarded Tenant for Tenant's personal property and moving costs, leasehold value and business interruption shall be and remain the property of Tenant. D. WAIVER OF CCP SECTION 1265.130. Each party waives the provisions of California Civil Code Procedure Section 1265.130 allowing either party to petition the superior court to terminate this Lease as a result of a partial taking. 24. CASUALTY DAMAGE A. GENERAL. If the Premises or Building should be damaged or destroyed by fire, tornado, or other casualty (collectively, "Casualty"), Tenant shall give immediate written notice thereof to Landlord. Within thirty (30) days after Landlord's receipt of such notice, Landlord shall notify Tenant whether in Landlord's estimation material restoration of the Premises can reasonably be made within one hundred eighty (180) days from the date of such notice and receipt of required permits for such restoration. Landlord's determination shall be binding on Tenant. B. WITHIN 180 DAYS. If the Premises or Building should be damaged by Casualty to such extent that material restoration can in Landlord's estimation be reasonably completed within one hundred eighty (180) days after the date of such notice and receipt of required permits for such restoration, this Lease shall not terminate. Provided that insurance proceeds are received by Landlord to fully repair the damage, Landlord shall proceed to rebuild and repair the Premises in the manner determined by Landlord, except that Landlord shall not be required to rebuild, repair or replace any part of the Alterations which may have been placed on or about the Premises by Tenant. If the Premises are untenantable in whole or in part following such damage, the Rent payable hereunder during the period in which they are untenantable shall be abated proportionately, but only to the extent the Premises are unfit for occupancy. C. GREATER THAN 180 DAYS. If the Premises or Building should be damaged by Casualty to such extent that rebuilding or repairs cannot in Landlord's estimation be reasonably completed within one hundred eighty (180) days after the date of such notice and receipt of required permits for such rebuilding or repair, then Landlord shall have the option of either: (1) terminating this Lease effective upon the date of the occurrence of such damage, in which event the Rent shall be abated during the unexpired portion of <PAGE> 21 this Lease; or (2) electing to rebuild or repair the Premises diligently and in the manner determined by Landlord. Landlord shall notify Tenant of its election within thirty (30) days after Landlord's receipt of notice of the damage or destruction. Notwithstanding the above, Landlord shall not be required to rebuild, repair or replace any part of any Alterations which may have been placed, on or about the Premises by Tenant. If the Premises are untenantable in whole or in part following such damage, the Rent payable hereunder during the period in which they are untenantable shall be abated proportionately, but only to the extent of rental abatement insurance proceeds received by Landlord during the time and to the extent the Premises are unfit for occupancy. D. TENANT'S FAULT. Notwithstanding anything herein to the contrary, if the Premises or any other portion of the Building are damaged by Casualty resulting from the fault, negligence, or breach of this Lease by Tenant or any of Tenant's Parties, Base Rent and Additional Rent shall not be diminished during the repair of such damage and Tenant shall be liable to Landlord for the cost and expense of the repair and restoration of the Building caused thereby to the extent such cost and expense is not covered by insurance proceeds. E. INSURANCE PROCEEDS. Notwithstanding anything herein to the contrary, if the Premises or Building are damaged or destroyed and are not fully covered by the insurance proceeds received by Landlord or if the holder of any indebtedness secured by a mortgage or deed of trust covering the Premises requires that the insurance proceeds be applied to such indebtedness, then in either case Landlord shall have the right to terminate this Lease be delivering written notice of termination to Tenant within thirty (30) days after the date of notice to Landlord that said damage or destruction is not fully covered by insurance or such requirement is made by any such holder, as the case may be, whereupon this Lease shall terminate. F. WAIVER. This Paragraph 24 shall be Tenant's sole and exclusive remedy in the event of damage or destruction to the Premises or the Building. As a material inducement to Landlord entering into this Lease, Tenant hereby waives any rights it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil Code of California with respect to any destruction of the Premises, Landlord's obligation for tenantability of the Premises and Tenant's right to make repairs and deduct expenses of such repairs, or under any similar law, statute or ordinance now or hereinafter in effect. G. TENANT'S PERSONAL PROPERTY. In the event of any damage or destruction of the Premises or the Building, under no circumstances shall Landlord be required to repair any injury or damage to, or make any repairs or replacements of, Tenant's personal property. 25. HOLDING OVER Unless Landlord expressly consents in writing to Tenant's holding over, Tenant shall be unlawfully and illegally in possession of the Premises, whether or not Landlord accepts any rent from Tenant or any other person while Tenant remains in possession of the Premises without Landlord's written consent. If Tenant shall retain possession of the Premises or any portion thereof without Landlord's consent following the expiration of this Lease or sooner termination for any reason, then Tenant shall pay to Landlord for each day of such retention double the amount of daily rental as of the last month prior to the date of expiration or earlier termination. Tenant shall also indemnify, defense, protect and hold Landlord harmless from any loss, liability or cost, including consequential and incidental damages and reasonable attorneys' fees, incurred by Landlord resulting from delay by Tenant in surrendering the Premises, including, without limitation, any claims made by the succeeding tenant founded on such delay. Acceptance of Rent by Landlord following expiration or earlier termination of this Lease, or following demand by Landlord for possession of the Premises, shall not constitute a renewal of this Lease, and nothing contained in this Paragraph 25 shall waive Landlord's right of reentry or any other right. Additionally, if upon expiration or earlier termination of this Lease, or following demand by Landlord for possession of the Premises, Tenant has not fulfilled its obligation with respect to repairs and cleanup of the Premises or any other Tenant obligations as set forth in this Lease, the Landlord shall have the right to perform any such obligations as it deems necessary at Tenant's sole cost and expense, and any time required by Landlord to complete such obligations shall be considered a period of holding over and <PAGE> 22 the terms of this Paragraph 25 shall apply. The provisions of this Paragraph 25 shall survive any expiration or earlier termination of this Lease. 26. DEFAULT A. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an event of default on the part of Tenant: (1) ABANDONMENT. Abandonment or vacation of the Premises for a continuous period in excess of thirty (30) days. Tenant waives any right to notice Tenant may have under Section 1951.3 of the Civil Code of the State of California, the terms of this Paragraph 26.A being deemed such notice to Tenant as required by such Section 1951.3. (2) NONPAYMENT OF RENT. Failure to pay any installment of Rent or any other amount due and payable hereunder upon the date when said payment is due, as to which time is of the essence. (3) OTHER OBLIGATIONS. Failure to perform any obligation, agreement or covenant under this Lease other than those matters specified in subparagraphs (1) and (2) of this Paragraph 26.A, such failure continuing for fifteen (15) days after written notice of such failure, as to which time is of the essence. (4) GENERAL ASSIGNMENT. A general assignment by Tenant for the benefit of creditors. (5) BANKRUPTCY. The filing of any voluntary petition in bankruptcy by Tenant, or the filing of an involuntary petition by Tenant's creditors, which involuntary petition remains undischarged for a period of ninety (90) days. If under applicable law, the trustee in bankruptcy or Tenant has the right to affirm this Lease and continue to perform the obligations of Tenant hereunder, such trustee or Tenant shall, in such time period as may be permitted by the bankruptcy court having jurisdiction, cure all defaults of Tenant hereunder outstanding as of the date of the affirmance of this Lease and provide to Landlord such adequate assurances as may be necessary to ensure Landlord of the continued performance of Tenant's obligations under this Lease. (6) RECEIVERSHIP. The employment of a receiver to take possession of substantially all of Tenant's assets or Tenant's leasehold of the Premises, if such appointment remains undismissed or undischarged for a period of ninety (90) days after the order therefor. (7) ATTACHMENT. The attachment, execution or other judicial seizure of all or substantially all of Tenant's assets or Tenant's leasehold of the Premises, if such attachment or other seizure remains undismissed or undischarged for a period of ninety (90) days after the levy thereof. (8) INSOLVENCY. The admission by Tenant in writing of its inability to pay its debts as they become due. B. REMEDIES UPON DEFAULT. (1) TERMINATION. In the event of the occurrence of any event of default, Landlord shall have the right to give a written termination notice to Tenant, and on the date specified in such notice, Tenant's right to possession shall terminate, and this Lease shall terminate unless on or before such date all Rent and all costs and expenses incurred by or on behalf of Landlord hereunder shall have been paid by Tenant and all other events of default of this Lease by Tenant at the time existing shall have been fully remedied to the satisfaction of Landlord. At any time after such termination, Landlord may recover possession of the Premises or any part thereof and expel and remove therefrom Tenant and any other person occupying the same, including any subtenant or subtenants notwithstanding Landlord's consent to any sublease, by any lawful means, and again repossess and enjoy the Premises without prejudice to any of the remedies that Landlord may <PAGE> 23 have under this Lease, or at law or equity by any reason of Tenant's default or of such termination. Landlord hereby reserves the right, but shall not have the obligation, to recognize the continued possession of any subtenant. The delivery or surrender to Landlord by or on behalf of Tenant of keys, entry codes, or other means to bypass security at the Premises shall not terminate this Lease. (2) CONTINUATION AFTER DEFAULT. Even though an event of default may have occurred, this Lease shall continue in effect for so long as Landlord does not terminate Tenant's right to possession under paragraph 26.B.(1) hereof, and Landlord may enforce all of Landlord's rights and remedies under this Lease and at law or in equity, including without limitation, the right to recover Rent as it becomes due, and Landlord, without terminating this Lease, may exercise all of the rights and remedies of a landlord under Section 1951.4 of the Civil Code of the State of California or any successor code section. Acts of maintenance, preservation or efforts to lease the Premises or the appointment of a receiver under application of Landlord to protect Landlord's interest under this Lease or other entry by Landlord upon the Premises shall not constitute an election to terminate Tenant's right to possession. (3) INCREASED SECURITY DEPOSIT. If Tenant is in default under Paragraph 26.A.(2) hereof and such default remains uncured for ten (10) days after such occurrence or such default occurs more than three times in any twelve (12) months period Landlord may require that Tenant increase the security deposit to the amount of three times the current months rent at the time of the most recent default. C. DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State of California, or any successor code sections. Upon such termination, in addition to any other rights and remedies to which Landlord may be entitled under applicable law or at equity, Landlord shall be entitled to recover from Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts which had been earned at the time of termination, (2) the worth at the time of award of the amount by which the unpaid Rent and other amounts that would have been earned after the date of termination until the time of award exceeds the amount of such Rent loss that the Tenant proves could be reasonably avoided; (3) the worth at the time of award of the amount by which the unpaid Rent and other amounts for the balance of the Term after the time of award exceeds the amount of such Rent loss that the Tenant proves could be reasonably avoided; and (4) any other amount and court costs necessary to compensate Landlord for all 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. The "worth at the time of award" as used in (1) and (2) above shall be computed at the Applicable Interest Rate (defined below). The "worth at the time of award" as used in (3) above shall be computed by discounting such amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). If this Lease provides for any periods during the Term during which Tenant is not required to pay Base Rent or if Tenant otherwise receives a Rent concession, then upon the occurrence of an event of default, Tenant shall owe to Landlord the full amount of such Base Rent or value of such Rent concession, plus interest at the Applicable Interest Rate, calculated from the date that such Base Rent or Rent concession would have been payable. D. LATE CHARGE. In addition to its other remedies, Landlord shall have the right without notice or demand to add to the amount of any payment required to be made by Tenant hereunder, and which is not paid and received by Landlord on or before the first day of each calendar month, an amount equal to ten percent (10%) of the delinquency for each month or portion thereof that the delinquency remains outstanding to compensate Landlord for the loss of the use of the amount not paid and the administrative costs caused by the delinquency, the parties agreeing that Landlord's damage by virtue of such delinquencies would be extremely difficult and impracticable to compute and the amount stated herein represents a reasonable estimate thereof. Any waiver by Landlord of any late charges or failure to claim the same shall not constitute a waiver of other late charges or any other remedies available to Landlord. E. INTEREST. Interest shall accrue on all sums not paid when due hereunder at the lesser of eighteen percent (18%) per annum or the maximum interest rate allowed by law ("APPLICABLE INTEREST RATE") from the due date until paid. F. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of the parties are cumulative and not alternative, to the extent permitted by law and except as otherwise provided herein. <PAGE> 24 27. LIENS Tenant shall at all times keep the Premises and the Project free from liens arising out of or related to work or services performed, materials or supplies furnished or obligations incurred by or on behalf of Tenant or in connection with work made, suffered or done by or on behalf of Tenant in or on the Premises or Project. If Tenant shall not, within the ten (10) days following the imposition of any such lien, cause the same to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided herein and by law, the right, but not the obligation, to cause the same to be released by such means as Landlord shall reasonably deem proper, including payment of the claim giving rise to such lien. All sums paid by Landlord on behalf of Tenant and all expenses incurred by Landlord in connection therefor shall be payable to Landlord by Tenant on demand with interest at the Applicable Interest Rate as Additional Rent. Landlord shall have the right at all times to post and keep posed on the Premises any notices permitted or required by law, or which Landlord shall deem proper, for the protection of Landlord, the Premises, the Project and any other party having an interest therein, from mechanics' and materialmen's liens, and Tenant shall give Landlord not less than ten (10) business days prior written notice of the commencement of any work in the Premises or Project which could lawfully give rise to a claim for mechanics' or materialmen's liens to permit Landlord to post and record a timely notice of non-responsibility, as Landlord may elect to proceed or as the law may from time provide, for which purpose, if Landlord shall so determine, Landlord may enter the Premises. Tenant shall not remove any such notice posted by Landlord without Landlord's consent, and in any event not before completion of the work which could lawfully give rise to a claim for mechanics' or materialmen's liens. 28. SUBSTITUTION [SECTION DELETED] 29. TRANSFERS BY LANDLORD In the event of a sale or conveyance by Landlord of the Building or a foreclosure by any creditor of Landlord, the same shall operate to release Landlord from any liability upon any of the covenants or conditions, express or implied, herein contained in favor of Tenant, to the extent required to be performed after the passing of title to Landlord's successor-in-interest. In such event, Tenant agrees to look solely to the responsibility of the successor-in-interest of Landlord under this Lease with respect to the performance of the covenants and duties of "Landlord" to be performed after the passing of title to Landlord's successor-in-interest. This Lease shall not be affected by any such sale and Tenant agrees to attorn to the purchaser or assignee. Landlord's successor(s)-in-interest shall not have liability to Tenant with respect to the failure to perform any of the obligations of "Landlord," to the extent required to be performed prior to the date such successor(s)-in-interest became the owner of the Building. 30. RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS All covenants to be performed by Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant's sole cost and expense and without any abatement of Rent. If Tenant shall fail to pay any sum of money, other than Base Rent, required to be paid by Tenant hereunder or shall fail to <PAGE> 25 perform any other act on Tenant's part to be performed hereunder, including Tenant's obligations under Paragraph 11 hereof, and such failure shall continue for twenty (20) days after notice thereof by Landlord, in addition to the other rights and remedies of Landlord, Landlord may make any such payment and perform any such act on Tenant's part. In the case of an emergency, no prior notification by Landlord shall be required. Landlord may take such actions without any obligation and without releasing Tenant from any of Tenant's obligations. All sums so paid by Landlord and all incidental costs incurred by Landlord and interest thereon at the Applicable Interest Rate, from the date of payment by Landlord, shall be paid to Landlord on demand as Additional Rent. 31. WAIVER If either Landlord or Tenant waives the performance of any term, covenant or condition contained in this Lease, such waiver shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition contained herein, or constitute a course of dealing contrary to the expressed terms of this Lease. The acceptance of Rent by Landlord shall not constitute a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, regardless of Landlord's knowledge of such preceding breach at the time Landlord accepted such Rent. Failure by Landlord to enforce any of the terms, covenants or conditions of this Lease for any length of time shall not be deemed to waive or decrease the right of Landlord to insist thereafter upon strict performance by Tenant. Waiver by Landlord of any term, covenant or condition contained in this Lease may only be made by a written document signed by Landlord, based upon full knowledge of the circumstances. 32. NOTICES Each provision of this Lease or of any applicable governmental laws, ordinances, regulations and other requirements with reference to sending, mailing, or delivery of any notice or the making of any payment by Landlord or Tenant to the other shall be deemed to be complied with when and if the following steps are taken: A. RENT. All rent and other payments required to be made by Tenant to Landlord hereunder shall be payable to Landlord at Landlord's Remittance Address set forth in the Basic Lease Information, or at such other address as Landlord may specify from time to time by written notice delivered in accordance herewith. Tenant's obligations to pay Rent and any other amounts to Landlord under the terms of this Lease shall not be deemed satisfied until such Rent and other amounts have been actually received by Landlord. B. OTHER. All notices, demands, consents and approvals which may or are required to be given by either party to the other hereunder shall be in writing and either personally delivered, sent by commercial overnight courier, mailed, certified or registered, postage prepaid, and in each case addressed to the party to be notified at the Notice Address for such party as specified in the Basic Lease Information or to such other place as the party to be notified may from time to time designate by at least fifteen (15) days notice to the notifying party. Notices shall be deemed served upon receipt or refusal to accept delivery. Tenant appoints as its agent to receive the service of all default notices and notice of commencement of unlawful detainer proceedings the person in charge of or apparently in charge of occupying the Premises at the time, and, if there is no such person, then such service may be made by attaching the same on the main entrance of the Premises. C. REQUIRED NOTICES. Tenant shall immediately notify Landlord in writing of any notice of a violation or a potential or alleged violation of any Regulation that relates to the Premises or the Project, or of any inquiry, investigation, enforcement or other action that is instituted or threatened by any governmental or regulatory agency against Tenant or any other occupant of the Premises, or any claim that is instituted or threatened by any third party that relates to the Premises or the Project. <PAGE> 26 33. ATTORNEYS' FEES If Landlord places the enforcement of this Lease, or any part thereof, or the collection of any Rent due, or to become due hereunder, or recovery of possession of the Premises in the hands of an attorney, Tenant shall pay to Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs, whether incurred without trial, at trial, appeal or review. In any action which Landlord or Tenant brings to enforce its respective rights hereunder, the unsuccessful party shall pay all costs incurred by the prevailing party including reasonable attorneys' fees, to be fixed the court, and said costs and attorneys' fees shall be a part of the judgment in said action. 34. SUCCESSORS AND ASSIGNS This Lease shall be binding upon and inure to the benefit of Landlord, its successors and assigns, and shall be binding upon and inure to the benefit of Tenant, its successors, and to the extent assignment is approved by Landlord as provided hereunder, Tenant's assigns. 35. FORCE MAJEURE If performance by a party of any portion of this Lease is made impossible by any prevention, delay, or stoppage caused by strikes, lockouts, labor disputes, acts of God, inability to obtain services, labor, or materials or reasonable substitutes for those items, government actions, civil commotions, fire or other casualty, or other causes beyond the reasonable control of the party obligated to perform, performance by that party for a period equal to the period of that prevention, delay, or stoppage is excused. Tenant's obligation to pay Rent, however, is not excused by this Paragraph 35. 36. SURRENDER OF PREMISES Tenant shall, upon expiration or sooner termination of this Lease, surrender the Premises to Landlord in the same condition as existed on the date Tenant originally took possession thereof, including, but not limited to, all interior walls cleaned, all interior painted surfaces repainted in the original color, all holes in the walls repaired, all carpets shampooed and cleaned, and all floors cleaned, waxed, and free of any Tenant-introduced marking or painting, all to the reasonable satisfaction of Landlord, ordinary wear and tear excepted. Tenant shall remove all of its debris from the Project. At or before the time of surrender, Tenant shall comply with the terms of Paragraph 12.A. hereof with respect to Alterations to the Premises and all other matters addressed in such Paragraph. If the Premises are not so surrendered at the expiration or sooner termination of this Lease, the provisions of Paragraph 25 hereof shall apply. All keys to the Premises or any part thereof shall be surrendered to Landlord upon expiration or sooner termination of the Term. Tenant shall give written notice to Landlord at least thirty (30) days prior to vacating the Premises and shall meet with Landlord for a joint inspection of the Premises at the time of vacating, but nothing contained herein shall be construed as an extension of the Term or as a consent by Landlord to any holder over by Tenant. In the event of Tenant's failure to give such notice or participate in such joint inspection, Landlord's inspection at or after Tenant's vacating the Premises shall conclusively be deemed correct for purposes of determining Tenant's responsibility for repairs and restoration. Any delay caused by Tenant's failure to carry out its obligations under this Paragraph 36 beyond the term hereof, shall constitute unlawful and illegal possession of the Premises under Paragraph 25 hereof. 37. PARKING So long as Tenant is occupying the Premises, Tenant and Tenant's Parties shall have the right to use up to the number of parking spaces, if any, specified in the Basic Lease Information on an unreserved, non-exclusive, first come, first served basis, for passenger-size automobiles, in the parking areas in the Project designated from time to time by Landlord for use in common by tenants of the Building. <PAGE> 27 Tenant may request additional parking spaces from time to time and if Landlord in its sole discretion agrees to make such additional spaces available for use by Tenant, such spaces shall be provided on a month-to-month unreserved and nonexclusive basis (unless otherwise agreed in writing by Landlord), and subject to such parking charges as Landlord shall determine, and shall otherwise be subject to such terms and conditions as Landlord may require. Tenant shall at all times comply and shall cause all Tenant's Parties and visitors to comply with all Regulations and any rules and regulations established from time to time by Landlord relating to parking at the Project, including any keycard, sticker or other identification or entrance system, and hours of operation, as applicable. Landlord shall have no liability for any damage to property or other items located in the parking areas of the Project, nor for any personal injuries or death arising out of the use of parking areas in the Project by Tenant or any Tenant's Parties except arising from or caused by Landlord's parties gross negligence, willful misconduct or criminal activity. Without limiting the foregoing, if Landlord arranges for the parking areas to be operated by an independent contractor not affiliated with Landlord, Tenant acknowledges that Landlord shall have no liability for claims arising through the acts or omissions of such independent contractor. In all events, Tenant agrees to look first to its insurance carrier and to require that Tenant's Parties look first to their respective insurance carriers for payment of any losses sustained in connection with any use of the parking areas. Landlord reserves the right to assign specific spaces, and to reserve spaces for visitors, small cars, disabled person or for other tenants or guests, and Tenant shall not park and shall not allow Tenant's Parties to park in any such assigned or reserved spaces. Tenant may validate visitor parking by such method as Landlord may approve, at the validation rate from time to time generally applicable to visitor parking. Landlord also reserves the right to alter, modify, relocate or close all or any portion of the parking areas in order to make repairs or perform maintenance service, or to restripe or renovate the parking areas, or if required by casualty, condemnation, act of God, Regulations or for any other reason deemed reasonable by Landlord. Tenant shall pay to Landlord (or Landlord's parking contractor, if so directed in writing by Landlord), as Additional Rent hereunder, the monthly charges established from time to time by Landlord for parking under the Building should such spaces become available and should Landlord and Tenant agree that t shall lease such spaces. Such parking charges shall be payable in advance with Tenant's payment of Basic Rent. No deductions from the monthly parking charge shall be made for days on which the Tenant does not use any of the parking spaces entitled to be used by Tenant. 38. MISCELLANEOUS A. GENERAL. The term "Tenant" or any pronoun used in place thereof shall indicate and include the masculine or feminine, the singular or plural number, individuals, firms or corporations, and their respective successors, executors, administrators and permitted assigns, according to the context hereof. B. TIME. Time is of the essence regarding this Lease and all of its provisions. C. CHOICE OF LAW. This Lease shall in all respects be governed by the laws of the State of California. D.

Tenant accepts the area of the Premises as specified in the Basic Lease Information as the approximate area of the Premises for all purposes under this Lease, and acknowledges and agrees that no other definition of the area (rentable, usable or otherwise) of the Premises shall apply. Tenant shall in no event be entitled to a recalculation of the square footage of the Premises, rentable, usable or otherwise, and no recalculation, if made, irrespective of its purpose, shall reduce Tenant's obligations under this Lease in any manner, including without limitation the amount of Base Rent payable by Tenant or Tenant's Proportionate Share of the Building and of the Project. F. SEVERABILITY. If, for any reason whatsover, any of the provisions hereof shall be unenforceable or ineffective, all of the other provisions shall be an remain in full force and effect. G. RECORDATION. Tenant shall not record this Lease or a short form memorandum hereof. H. EXAMINATION OF LEASE. Submission of this Lease to Tenant does not constitute an option or offer to lease and this Lease is not effective otherwise until execution and delivery by both Landlord and Tenant. I. ACCORD AND SATISFACTION. No payment by Tenant of a lesser amount than the total Rent due nor any endorsement on any check or letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction of full payment of Rent, and Landlord may accept such payment without prejudice to Landlord's right to recover the balance of such Rent or to pursue other remedies. All offers by or on behalf of Tenant of accord and satisfaction are hereby rejected in advance. J. EASEMENTS. Landlord may grant easements on the Project and dedicate for public use portions of the Project without Tenant's consent; provided that no such grant or dedication shall materially interfere with Tenant's Permitted Use of the Premises. Upon Landlord's request, Tenant shall execute, acknowledge and deliver to Landlord documents, instruments, maps, and plats necessary to effectuate Tenant's covenants hereunder. K. DRAFTING AND DETERMINATION PRESUMPTION. The parties acknowledge that this Lease has been agreed to by both the parties, that both Landlord and Tenant have consulted with attorneys with respect to the terms of this Lease and that no presumption shall be created against Landlord because Landlord drafted this Lease. Except as otherwise specifically set forth in this Lease, with respect to any consent, determination or estimation of Landlord required or allowed in this Lease or requested of Landlord, Landlord's consent, determination or estimation shall not be unreasonably withheld by Landlord. If Landlord fails to respond to any request for its consent within the time period, if any, specified in this Lease, Landlord shall be deemed to have disapproved such request. L. EXHIBITS. The Basic Lease Information, and the Exhibits, addenda and attachments attached hereto are hereby incorporated herein by this reference and made a part of this Lease as though fully set forth herein. M. 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 or in the vicinity of the Building shall in no way affect this Lease or impose any liability on Landlord. N. NO THIRD PARTY BENEFIT. This Lease is a contract between Landlord and Tenant and nothing herein is intended to create any third party benefit. O. QUIET ENJOYMENT. Upon payment by Tenant of the Rent, and upon the observance and performance of all of the other covenants, terms and conditions on Tenant's part to be observed and performed, Tenant shall peaceably and quietly hold and enjoy the Premises for the term hereby demised without hindrance or interruption by Landlord or any other person or persons lawfully or equitably claiming by, thorugh or under Landlord, subject, nevertheless, to all of the other terms and conditions of this Lease. <PAGE> 29 Landlord shall not be liable for any hindrance, interruption, interference or disturbance by other tenants or third persons, nor shall Tenant be released from any obligations under this Lease because of such hindrance, interruption, interference or disturbance.

(3) If required by landlord or any lender of Landlord, all work by Tenant or Tenant's contractor or agents shall be done with union labor in accordance with all union labor agreements applicable to the trades being employed. (4) All work by Tenant or Tenant's contractor or agents shall be scheduled through Landlord. (5) Tenant or Tenant's contractor or agents shall arrange for necessary utility, hoisting and elevator service with Landlord's contractor and shall pay such reasonable charges for such services as may be charged by Tenant's or Landlord's contractor. (6) Tenant's entry to the Premises for any purpose, including, without limitation, inspection or performance of Tenant construction by Tenant's agents, prior to the date Tenant's obligation to pay rent commences shall be subject to all the terms and conditions of the Lease except the payment of Rent. Tenant's entry shall mean entry by Tenant, its officers, contractors, licensees, agents, servants, employees, guests, invitees, or visitors. (7) Tenant shall promptly reimburse Landlord upon demand for any reasonable expense actually incurred by the Landlord by reason of faulty work done by Tenant or its contractors or by reason of any delays caused by such work, or by reason of inadequate clean-up. 6. Completion and Rental Commencement Date A. Tenant's obligation to pay Rent under the Lease shall commence on the applicable date described in Paragraph 2 of the Lease. However: (1) If Tenant delays in preparing or approving the Space Plans or the Plans, or fails to approve the estimate of the cost of the Tenant Improvements or any other matter requiring Tenant's approval, or to pay the excess cost of Tenant Improvements, in each case within the time limits specified herein; or (2) If the construction period is extended because Tenant requests any changes in construction, or modifies the approved Plans or if the same do not comply with applicable Regulations; or (3) If Landlord is otherwise delayed in the construction of the Tenant Improvements for any act or omission of or breach by Tenant or anyone performing services on behalf of Tenant or on account of any work performed on the Premises by Tenant or Tenant's contractors or agents, then the date described in Paragraph 2 of the Lease shall be deemed to be accelerated by the total number of days of Tenant delays described in (a) through (c) above (each, a "Tenant Delay"), calculated in accordance with the provisions of Paragraph 6.2 below. B. If the Term of the Lease has not already commenced pursuant to the provisions of Paragraph 2 of the Lease and substantial completion of the Tenant Improvements has been delayed on account of any Tenant Delays, then upon actual substantial completion of the Tenant Improvements (as defined in <PAGE> 41 Paragraph 2 of the Lease), Landlord shall notify Tenant in writing of the date substantial completion of the Tenant Improvements would have occurred but for such Tenant Delays, and such date shall thereafter be deemed to be the Term Commencement Date for all purposes under the Lease. Tenant shall pay to Landlord, within three (3) business days after receipt of such written notice (which notice shall include a summary of Tenant Delays), the per diem Base Rent times the number of days between the date the Term Commencement Date would have otherwise occurred but for the Tenant Delays (as determined by the Space Planner or Landlord's contractor), and the date of actual substantial completion of the Tenant Improvements. C. Promptly after substantial completion of the Tenant Improvements, Landlord shall give notice to Tenant and Tenant shall conduct an inspection of the Premises with a representative of Landlord and develop with such representative of Landlord a punchlist of items of the Tenant Improvements that are not complete or that require corrections. Upon receipt of such punchlist, Landlord shall proceed diligently to remedy such items at Landlord's cost and expense provided such items are part of the Tenant Improvements to be constructed by Landlord hereunder and are otherwise consistent with Landlord's obligations under this Improvement Agreement and provided Tenant has fully paid Landlord for the cost of the Tenant Improvements exceeding the Tenant Improvement Allowance (with any dispute between Landlord and Tenant pertaining thereto to be resolved by the Space Planner or Landlord's general contractor). Substantial completion shall not be delayed notwithstanding delivery of any such punchlist. D. A default under this Improvement Agreement shall constitute a default under the Lease, and the parties shall be entitled to all rights and remedies under the Lease in the event of a default hereunder by the other party (notwithstanding that the Term thereof has not commenced). E. Without limiting the "as-is" provisions of the Lease, except for the Tenant Improvements, if any, to be constructed by Landlord pursuant to this Improvement Agreement, Tenant accepts the Premises in its "as-is" condition and acknowledges that it has had an opportunity to inspect the Premises prior to signing the Lease. <PAGE> 42 SCHEDULE 1 TO EXHIBIT C BASE BUILDING WORK Landlord, at Landlord's sole cost and expense shall perform the following: Replacement of ceiling in fire corridor on the second floor; Replacement of floor covering in fire corridor on the second floor; Replacement of lighting on the second floor, if floor necessary, in fire corridor; Upgrade of restrooms on the second floor. <PAGE> 43 SCHEDULE 2 TO EXHIBIT C BUILDING STANDARDS The following constitutes the Building Standard tenant improvements ("STANDARDS") in the quantities specified: (to be provided per construction drawings)
