                               incurred by Landlord under this Lease and not
                               otherwise reimbursed by tenants of the Project.

                     b.        As soon as possible after the beginning' of each
                               calendar year, Landlord shall give to Tenant a
                               statement of the amount of the Operating Costs
                               Increase and any other additional rent payable by
                               Tenant hereunder for the previous year, all of
                               which shall be due and payable upon receipt of
                               the statement. In addition, for each year after
                               the Base Year, or portion thereof, Tenant shall
                               pay Tenant's Project Proportionate Share and
                               Tenant's Building Proportionate Share of
                               Landlord's good faith estimate of the Operating
                               Costs Increase for the following year. This
                               estimated amount shall be divided into twelve
                               equal monthly installments. Tenant shall pay to
                               Landlord, concurrently with the regular monthly
                               rent payment next due following the receipt of
                               such statement, an amount equal to one monthly
                               installment multiplied by the number of months
                               from January in the calendar year in which said
                               statement is submitted to the month of such
                               payment, both months inclusive. Subsequent
                               installments shall be payable concurrently with
                               the regular monthly rent payments for the balance
                               of that calendar year and shall continue until
                               the next calendar year's statement is rendered..
                               If; in any calendar year, the actual amount of
                               the Operating Costs Increase Tenant owes is less
                               than the estimate for that year, then upon
                               receipt of Landlord's statement, any overpayment
                               made by Tenant shall be credited towards all
                               payments thereafter due under this Article 6.3,
                               and the estimated monthly installments of
                               Tenant's share of Operating Costs Increase shall
                               be adjusted to reflect such lower Project
                               Operating Costs for the most recent year. If the
                               actual amount of the Operating Costs Increase
                               Tenant owes is more than the estimate for that
                               year, Tenant shall immediately pay any such
                               increase to Landlord.

                     c.        Even though the Lease Term has expired and Tenant
                               has vacated the Premises, when the final
                               determination is made of the amount Tenant owes
                               under this Section for the year in which this
                               Lease terminates, Tenant shall immediately pay
                               any increase due over the estimated expenses paid
                               and, conversely, provided Tenant is not in
                               default under this Lease, any overpayment made in
                               the event said expenses decrease shall be rebated
                               by Landlord to Tenant.

                     d.        All increases in Project Operating Costs shall be
                               determined separately and without regard to
                               changes or adjustments in Property Taxes or
                               Insurance Charges for the Project.

                               costs incurred because the Landlord or another
                               tenant violated the terms of any lease; (ii)
                               interest on debt or amortization payments on

                               (iv) repairs or other work needed because of

                               Property because of tenant's negligence or

                        accordance with the requirements of Section 6.3 of this
                        Lease. All increases in Property Taxes for each year of
                        this Lease shall be determined separately and without
                        regard to changes or adjustments in Project Operating
                        Costs or Insurance Charges for the Project.

           6.5.      Insurance Charges. Tenant agrees to pay to Landlord, as
                     additional rent, Tenant's Project Proportionate Share of

                     assumes or agrees to pay to Landlord under this Lease shall

                     Base Rent is sometimes referred to as the "Rent"). The Rent
                     shall be paid to the Landlord (or other person that
                     Landlord may designate), and at such place as Landlord may
                     from time to time designate in writing, without any prior
                     notice or demand therefor and without deduction or offset,
                     in lawful money of the United States of America.

                     other charges to be paid by Tenant hereunder, Tenant shall
                     reimburse Landlord upon demand for any and all taxes
                     payable by Landlord (other than net income taxes) which are
                     not otherwise reimbursable under this Lease pursuant to
                     Section 6.4 hereof, whether or not now customary or within
                     the contemplation of the parties, where such taxes are
                     upon, measured by or reasonably attributable to (i) the
                     costs or value of Tenant's equipment, furniture, fixtures
                     and other personal property located in the Premises, or the
                     cost or value of any leasehold improvements made in or to
                     the Premises by or for Tenant, other than Tenant
                     Improvements made by Landlord, regardless of whether title
                     to such improvements is held by Tenant or Landlord; (ii)
                     the gross or net Rent payable under this Lease, including,
                     without limitation, any rental or gross receipts, tax
                     levied by any taxing authority with respect to the receipt
                     of the Rent hereunder; (iii) the possession, leasing,
                     operation, management, maintenance or alteration, repair,
                     use or occupancy by Tenant of the Premises or any portion
                     thereof, or (iv) this transaction or any document to which
                     Tenant is a party creating or transferring an interest or
                     an estate in the Premises. If it becomes unlawful for
                     Tenant to reimburse Landlord for any costs as required
                     under this Lease, the Base Rent shall be revised to net
                     Landlord the same net Rent after imposition of any tax or
                     other charge upon Landlord as would have been payable to
                     Landlord but for the reimbursement being unlawful.

           6.8.      Audit. Landlord shall retain its records regarding Common
                     Area Maintenance Charges for a period of at least one (1)
                     year following the final billing for the calendar year in
                     question. At any time during such one (1) year period, upon
                     reasonable advance written notice to Landlord, but not more
                     frequently than once in any calendar year, Tenant shall
                     have the right to audit all of Landlord's or Landlord's
                     agent's records pertaining to Common Area Maintenance
                     Charges by a representative of Tenant's choice. If such
                     audit reveals that Landlord's annual statement was
                     incorrect, any over-billing discovered in the course of
                     such audit shall be refunded to Tenant within thirty (30)
                     days of Landlord's receipt of a copy of the audit, unless
                     Landlord disputes the audit, and any underbilling shall be
                     paid by Tenant to Landlord within thirty (30) days of the
                     audit. In the event that any overbilling exceeds the amount
                     actually due from Tenant for the year by 


                                    4 of 17                  INITIALS ____ ____

                      three percent (3%) or more, then Landlord shall reimburse
                      Tenant for the reasonable costs of the audit. If Landlord
                      disputes the results of Tenant's audit, Landlord and
                      Tenant shall attempt to resolve such dispute in good
                      faith. If Landlord and Tenant are unable to do so within
                      thirty (30) days, then Landlord shall commission a second
                      audit by an accounting firm selected by Landlord. The
                      results of such second audit shall be deemed conclusive as
                      to any such dispute. Landlord shall pay the cost of such
                      second audit unless such second audit confirms amounts
                      actually due from Tenant for the year are within the three
                      percent (3%) noted above, in which event Tenant shall pay
                      for the second audit. In any event, Tenant shall continue
                      to pay all Rent and Excess Operating Costs, Additional
                      Rent, as otherwise provided by this Lease until the
                      dispute is resolved or the results of the second audit are
                      available.

7.         INTEREST AND LATE CHARGES.

           If Tenant fails to pay, when due, any Rent or other amounts or
           charges which Tenant is obligated to pay under the terms of this
           Lease, the unpaid amounts shall bear interest from the due date until
           the date paid at the prime rate then established by Bank Of America
           plus two percent per annum, but not to exceed the maximum rate then
           allowed by law. Tenant acknowledges that the late payment of any
           installment of Rent or other charges will cause Landlord to lose the
           use of that money and incur costs and expenses not contemplated under
           this Lease, including without limitation, administrative and
           collection costs and processing and accounting expenses, the exact
           amount of which is extremely difficult to ascertain. Therefore, in
           addition to interest, if any such installment is not received by
           Landlord within five (5) days from the date it is due, Tenant shall
           pay Landlord a late charge equal to ten percent (10%) of such
           installment. By affixing their initials where indicated below,
           Landlord and Tenant agree that this late charge represents a
           reasonable estimate of such costs and expenses and is fair
           compensation to Landlord for the loss suffered from such late payment
           by Tenant. Acceptance of any interest or late charge shall not
           constitute a waiver of Tenant's defaults with respect to such late
           payment by Tenant nor prevent Landlord from exercising any other
           rights or remedies available to Landlord under this Lease.

8.         SECURITY DEPOSIT.

           Tenant agrees to deposit with Landlord a Security Deposit equal to
           one Monthly Installment of Annual Base Rent upon execution of this
           Lease as security for Tenant's faithful performance of its
           obligations under this Lease. Tenant may not credit the Security
           Deposit to any rent, or additional rent, due under the lease,
           including rent due during the last month of the Term of this Lease.
           Landlord and Tenant agree that the Security Deposit may be commingled
           with funds of Landlord, and Landlord shall have no obligation or
           liability for payment of interest on such deposit. Tenant shall not
           mortgage, assign, transfer or encumber the Security Deposit without
           the prior written consent of Landlord, and any attempt by Tenant to
           do so shall be void, without full force or effect and shall not be
           binding upon Landlord.

           If Tenant fails to pay any Rent or other amount when due and payable
           under this Lease, or fails to perform any of the terms hereof,
           Landlord may appropriate and apply or use all, or any portion, of the
           Security Deposit for Rent payments or any other amount then due and
           unpaid, for payment of any amount for which Landlord has become
           obligated as a result of Tenant's default or breach, or for any loss
           or damage sustained by Landlord as a result of Tenant's default under
           or breach of any term of this Lease. Landlord may so apply or use
           this deposit without prejudice to any other remedy Landlord may have
           by reason of Tenant's default or breach. If any portion of the
           Security Deposit is so used or applied, Tenant shall, within ten days
           after written demand therefor, restore the Security Deposit to the
           full amount originally deposited; Tenant's failure to do so shall
           constitute an event of default hereunder and Landlord shall have the
           right to exercise any remedy provided for at Section 28 hereof.
           Within thirty (30) days after the Term has expired or Tenant has
           vacated the Premises, whichever shall last occur, and provided Tenant
           is not then in default of any of its obligations hereunder, Landlord
           shall return the Security Deposit or any balance thereof to Tenant,
           or if Tenant has assigned its interest under this Lease, to the last
           assignee of Tenant. Such Security Deposit shall be returned to Tenant
           within thirty (30) days of Tenant's vacation of the Premises provided
           that the Premises is in satisfactory condition as per Paragraph 12.8
           of the Lease Agreement. If any portion of the Security Deposit is
           retained by Landlord, Landlord shall provide Tenant with a statement
           setting for the amounts and reasons for retention. IF Landlord sells
           its interest in the Premises, Landlord may deliver this deposit to
           the purchaser of Landlord's interest and thereupon be relieved of any
           further liability or obligation to Tenant with respect to the
           Security Deposit.

           of components for telecommunications equipment. Tenant shall not use

           expenses, shall comply with all laws, ordinances, regulations, rules

           use or occupancy of the Premises, impose any duty upon Tenant or
           Landlord with respect to the Premises or its use or occupation. A
           judgment of any court of competent jurisdiction or the admission by
           Tenant of any action or proceeding against Tenant or that Tenant has
           violated any such law, ordinances, regulations, rules and/or
           directives in the use of the Premises shall be deemed to be a
           conclusive determination of that fact as between Landlord and Tenant.
           Tenant shall not do or permit to be done anything which will
           invalidate or increase the cost of any fire, extended coverage or

                               negligence or intentional misconduct.

                     qualified and licensed contractors, mechanics and other
                     personnel approved in advance by Landlord, and such work

                     performed and diligently pursued to completion in
                     conformance with applicable building codes. Tenant shall
                     supply Landlord with copies of as-built drawings and

                     any such work be performed by Landlord's contractor, in
                     which case the cost of such work shall be paid for before
                     commencement of the work.

                     indemnify, defend against and hold Landlord free and
                     harmless from all liability, loss, damage, costs,
                     attorneys' fees and any other expense incurred on account
                     of claims by any person performing work or furnishing
                     materials or supplies for Tenant or any person claiming
                     under Tenant.

                     Tenant shall keep Tenant's leasehold interest, and any
                     additions or improvements which are or become the property
                     of Landlord under this Lease, free and clear of all
                     attachment or judgment liens before the actual commencement
                     of any work for which a claim or lien may be filed. Tenant
                     shall give Landlord ten days written notice of the intended
                     commencement date to enable Landlord to post notices of
                     nonresponsibility or any other notices which Landlord deems
                     necessary for the proper protection of Landlord's interest
                     in the Premises or the Project, and Landlord shall have the

                     reasonable time.

                     Tenant provide to Landlord, at Tenant's expense, a lien and
                     completion bond in an amount equal to at least one and
                     one-half times the total estimated cost to any additions,
                     alterations or improvements to be made in or to the
                     Premises to protect Landlord against any liability for
                     mechanic's and materialman's liens and to insure timely
                     completion of the work. Nothing contained in this Section
                     13.3 shall relieve Tenant of its obligation under Section
                     13.2 to keep the Premises and the Project free of all
                     liens.

           13.4.     Unless their removal is required by Landlord as provided in
                     Section 13.1, all additions, alterations and improvements
                     made to the Premises shall become the property of Landlord
                     and shall remain upon and be surrendered with the Premises
                     as a part thereof upon the expiration of the Lease Term;

                     fixtures which can be removed without damage to the
                     Premises shall remain the property of Tenant and may be
                     removed, subject to the provisions of Section 14.2.

           13.5.     Tenant shall be required to remove only those Alterations
                     and Additions which Landlord identifies in writing, at the
                     time Landlord consents to construction, as an Alteration or
                     Addition which Landlord desires to be removed upon
                     termination or expiration of this Lease.

                                          such assignment or subletting, shall
                                          be paid to Landlord as additional rent
                                          under this Lease without affecting or
                                          reducing any other obligations of
                                          Tenant hereunder.

                     c.        If Tenant is a corporation, partnership or other
                               entity, the transfer of controlling interest of
                               Tenant during the terms shall constitute an
                               assignment for purposes of this Section 17.

                     d.        Notwithstanding the provisions of Paragraphs
                               17(a) and 17(b) above, Tenant may assign this
                               Lease or sublet the Premises or any portion
                               thereof, without Landlord's consent and without
                               extending any recapture or termination option to
                               Landlord, to any corporation or entity which
                               controls, is controlled by or is under common
                               control with Tenant, or to any corporation
                               resulting from a merger or consolidation with
                               Tenant, or to any person or entity which acquires
                               all the assets of Tenant's business as a going
                               concern, provided that (i) the assignee or
                               sublessee assumes, in full, the obligations of
                               Tenant under this Lease, (ii) Tenant remains
                               fully liable under this Lease, and (iii) the use
                               of the Premises under Section 9 remains
                               unchanged.

                     e.        No subletting or assignment shall release Tenant
                               of Tenant's obligations under this Lease or alter
                               the primary liability of Tenant to pay the Rent
                               and to perform all other obligations to be
                               performed by Tenant hereunder. The acceptance of
                               Rent by Landlord from any other person shall not
                               be deemed to be a waiver by Landlord of any
                               provision hereof. Consent to one assignment or
                               subletting shall not be deemed consent to any
                               subsequent assignment or subletting. In the event
                               of default by an assignee or subtenant of Tenant
                               or any successor of Tenant in the performance of
                               any of the terms hereof, Landlord may proceed
                               directly against Tenant without the necessity of


                                    9 of 17                  INITIALS ____ ____

                               exhausting remedies against such assignee,
                               subtenant or successor. Landlord may, if Tenant
                               does not provide Landlord with a current mailing
                               address to notify Tenant, consent to subsequent
                               assignment of the Lease or subletting or
                               amendments or modifications to the Lease with
                               assignees of Tenant, without notifying Tenant,
                               and without obtaining its or their consent
                               thereto and any such actions shall not relieve
                               Tenant of liability under this Lease.

                     f.        If Tenant assigns the Lease or sublets the
                               Premises or requests the consent of Landlord to
                               any assignment or subletting or if Tenant
                               requests the consent of Landlord for any act that
                               Tenant proposes to do, then Tenant shall, upon
                               demand, pay Landlord an administrative fee of
                               five hundred and 00/100 Dollars ($500.00) plus
                               any attorneys' fees reasonably incurred by
                               Landlord in connection with such act or request.
                               Such administrative fee shall be increased
                               annually by the same percentage as Annual Base
                               Rent is increased pursuant to Section 6.2 hereof.

18.        HOLDING OVER.

           If after the expiration or earlier termination of the Term, as it may
           be extended, Tenant remains in possession of the Premises with or
           without Landlord's consent (express or implied), Tenant shall become
           a tenant from month to month only, upon all the provisions of this
           Lease (except as to Lease Term and Annual Base Rent), but the
           "Monthly Installments of Annual Base Rent" payable by Tenant shall be
           increased to one hundred fifty percent (150%) of the Monthly
           Installments of Annual Base Rent payable by Tenant at the expiration
           of the Lease Term. Such monthly rent shall be payable in advance on
           or before the first day of each month. If either party desires to
           terminate such month to month tenancy, it shall give the other party
           not less than thirty (30) days advance written notice of the date of
           termination.

           19.       SURRENDER OF PREMISES.

                     a.        Tenant shall peaceably surrender the Premises to
                               Landlord on the Expiration Date, in broom-clean
                               condition and in as good condition as when Tenant
                               took possession, except for (i) reasonable wear
                               and tear, (ii) loss by fire or other casualty,
                               and (iii) loss by condemnation. On or before the
                               Expiration Date, Tenant shall, on Landlord's
                               request, remove Tenant's Property and repair all
                               damage to the Premises or Building caused by such
                               removal.

                     b.        If Tenant abandons or surrenders the Premises, or
                               is dispossessed of the Premises by process of law
                               or otherwise, any of Tenant's Property left on
                               the Premises shall be deemed to be abandoned,
                               and, at Landlord's option, title shall pass to
                               Landlord under this Lease as by a bill of sale.
                               If Landlord elects to remove all or any part of
                               such Tenant's Property, the cost of removal,
                               including repairing any damage to the Premises or
                               Building caused by such removal, including court
                               costs and attorneys' fees and storage charges on
                               such effects, for any length of time that the
                               same shall be in Landlord's possession, shall be
                               paid by Tenant. Landlord may, at its option,
                               without notice, sell said effects, or any of the
                               same at private sale and without legal process,
                               for such price as Landlord may obtain and apply
                               the proceeds of such sale upon any amounts due
                               under this Lease from Tenant to Landlord and upon
                               the expense incident to the removal and sale of
                               said effects. On the Expiration Date, Tenant
                               shall surrender all keys to the Premises.

20.        DESTRUCTION OR DAMAGE.

                     a.        If the Premises or the portion of the Project
                               reasonably necessary for Tenant's occupancy is
                               damaged by fire, earthquake, act of God, the
                               elements or other casualty, Landlord shall,
                               subject to the provisions of this Section,
                               promptly repair the damage, if such repairs can,
                               in Landlord's opinion, be completed within ninety
                               (90) days. If Landlord determines that repairs
                               can be completed within ninety (90) days, this
                               Lease shall remain in full force and effect.

                     b.        If in Landlord's opinion, such repairs to the
                               Premises or any portion of the Project reasonably
                               necessary for Tenant's occupancy cannot be
                               completed within ninety (90) days, Landlord may
                               elect, upon written notice to Tenant given within
                               thirty (30) days after the date of such fire or
                               other casualty, to repair such damage, in which
                               event this Lease shall continue In full force and
                               effect, or if Landlord does not so elect to make
                               such repairs, this Lease shall terminate as of
                               the date of such fire or other casualty. If,
                               however, the damage is limited to the interior of
                               the Premises, then if Landlord does not elect to
                               repair the Premises, Tenant shall have the
                               option, at its expense, by written notice to
                               Landlord within fifteen (15) days after receipt
                               of Landlord's notice that it will not repair, to
                               repair the Premises and then keep this Lease in
                               effect. If Tenant shall repair the premises, then
                               any insurance proceeds attributable to the damage
                               may be used by Tenant to pay the cost of such
                               repair.

                     c.        If the Premises are to be repaired under this
                               Section, Landlord shall repair at its cost any
                               injury or damage to the Project outside of the
                               Premises and shall pay the cost of restoring the
                               Premises to their condition prior to the damage,
                               except that Tenant shall be responsible for
                               payment of the cost of the repair, restoration
                               and replacement of any Leasehold Improvements and
                               Tenant's Property in excess of the Tenant's
                               Improvements established in the Addendum,
                               Paragraphs 47 and 48 and the attached Exhibit
                               "C". Landlord shall not be liable for any loss of
                               business, inconvenience or annoyance arising from
                               any repair or restoration of any portion of the
                               Premises or the Project as a result of any damage
                               from fire or other casualty.

                     d.        This Lease shall be considered an express
                               agreement governing any case of damage to or
                               destruction of the Premises or the Project by
                               fire or other casualty, and any present or future
                               law

                               which purports to govern the rights of
                               Landlord and Tenant in such circumstances in the
                               absence of express agreement, shall have no
                               application.

21.        EMINENT DOMAIN.

                     a.        If the whole of the Project or Premises is
                               lawfully taken by condemnation or in any other
                               manner for any public or quasi-public purpose,
                               this Lease shall terminate as of the date of such
                               taking, and Rent shall be prorated to such date.
                               If less than the whole of the Project or Premises
                               is so taken, this Lease shall be unaffected by
                               such taking, provided that (i) Tenant shall have
                               the right to terminate this Lease by written
                               notice to Landlord given within ninety (90) days
                               after the date of such taking if twenty percent
                               (20%) or more of the Premises is taken and the
                               remaining area of the Premises is not reasonably
                               sufficient for Tenant to continue operation of
                               its business, or if such portion of the Project
                               other than the Premises is taken which makes it
                               reasonably impossible for Tenant to carry on its
                               operations, and (ii) Landlord shall have the
                               right to terminate this Lease by written notice
                               to Tenant given within ninety (90) days after the
                               date of such taking if the taking shall include
                               the Building of which the Premises are a part. If
                               either Landlord or Tenant so elects to terminate
                               this Lease, the Lease shall terminate on the
                               thirtieth (30th) day after either such notice.
                               The Rent shall be prorated to the date of
                               Termination. If this Lease continues in force
                               upon such partial taking, the Annual Base Rent
                               and Tenant's Proportionate Share of Project
                               Operating Expenses shall be equitably adjusted
                               according to the remaining Area of the Premises
                               and Project.

                     b.        In the event of any taking, partial or whole, all
                               of the proceeds of any award, judgment or
                               settlement payable by the condemning authority
                               shall be the exclusive property of Landlord, and
                               Tenant hereby assigns to Landlord all of its
                               right, title and interest in any award, judgment
                               or settlement from the condemning authority.
                               Tenant, however, shall have the right, to the
                               extent that Landlord's award is not reduced or
                               prejudiced, to claim from the condemning
                               authority (but not from Landlord) such
                               compensation as may be recoverable by Tenant in
                               its own right for relocation expenses and damage
                               to Tenant's personal property and after damage
                               recoverable by Tenant under applicable laws.

                     c.        In the event of a partial taking of the Premises
                               which does not result in a termination of this
                               Lease, Landlord shall restore the remaining
                               portion of the Premises as nearly as practicable
                               to its condition prior to the condemnation or
                               taking, but only to the extent of the Tenant
                               Improvement allowance established pursuant to
                               Addendum, Paragraphs 47 and 48 and the attached

                               sole cost and expense for the repair, restoration
                               and replacement of any other leasehold
                               improvements and Tenant's Property.

                               against and from liability and claims of any kind
                               for loss or damage to property of Tenant,
                               Landlord, or any other person, or for any injury
                               to or death of any person, arising out of: (i)
                               Tenant's use and occupancy of the Premises, or
                               any work, activity or other things allowed or
                               suffered by Tenant to be done in or on the
                               Premises; (ii) any breach or default by Tenant of
                               any of Tenant's obligations under this Lease;
                               (iii) any negligent or otherwise tortuous act or
                               omission of Tenant, its agents, employees,
                               invitees or contractors. Tenant shall, at
                               Tenant's expense, and by counsel satisfactory to
                               Landlord, defend Landlord in any action or
                               proceeding arising from any such claim and shall
                               indemnify Landlord against all costs, attorneys'
                               fees, and any other expenses incurred in such
                               action or proceeding. As a material part of the
                               consideration for Landlord's execution of this
                               Lease, Tenant hereby assumes all risk of damage
                               or injury to any person or property in, on or
                               about the Premises or Project from any cause,
                               except to the extent due to Landlord's gross
                               negligence or intentional misconduct.

                     b.        Landlord shall not be liable for injury or damage
                               which may be sustained by the person or property
                               of Tenant, its employees, invitees or customers,
                               or any other person in or about the Premises or
                               Project, caused by or resulting from fire,
                               explosion, falling plaster, steam, electricity,
                               gas, water or rain which may leak or flow or into
                               any part of the Premises, or from the breakage,
                               leakage, obstruction or other defects of pipes,
                               sprinklers, wires, appliances, plumbing, air
                               conditioning or lighting fixtures, or from any
                               other cause whatsoever, whether such damage or
                               injury results from conditions arising upon the
                               Premises or upon other portions of the Project
                               except to the extent resulting from the willful
                               misconduct or gross negligence of Landlord.
                               Landlord shall not be liable for any damage
                               arising from any act or omission of any other
                               tenant of the Project.

                     c.        Notwithstanding the provisions of Section 22(a)
                               and (b) to the contrary, Landlord or its agents

                               (ii) loss or damage to any property by theft or
                               otherwise. Landlord, its agents, employees and
                               invitees shall not be liable for interference
                               with light or other incorporeal hereditaments,
                               nor shall Landlord be liable for any latent
                               defect on the Premises or in the Building. Tenant
                               shall give prompt notice to Landlord in case of
                               fire or accidents on the Premises or in the
                               Building or of defects therein or in the fixtures

                               Tenant agrees that if Tenant does not take out
                               and maintain such insurance, Landlord may (but

                               to Landlord at such times as renewal certificates
                               are regularly provided to all other landlords of
                               Tenant. Such certificates shall provide that
                               Tenant's insurer shall endeavor to provide

                               replacement of the property so insured. Upon
                               termination of this Lease following a casualty as
                               set forth herein, the proceeds under (i) above
                               shall be paid to Landlord, and the proceeds under

                     d.        Not less than every two years during the Lease
                               Term, Landlord and Tenant shall mutually agree to
                               increases in all of Tenant's Insurance policy

                               as set forth in this Section. In the event
                               Landlord and Tenant cannot mutually agree upon
                               the amounts of said increases, then Tenant agrees
                               that all insurance policy limits as set forth in
                               this Section shall be adjusted for increases in

                               forth in Section 6.2 hereof for the adjustment of
                               the Annual Base Rent.

24.        WAIVER OF SUBROGATION.

           Landlord and Tenant each hereby waive all rights of recovery against
           the other and against the officers, employees, agents and
           representatives of the other, on account of loss by or damage to the
           waiving party or its property or the property of others under its
           control, to the extent that such loss or damage is insured against
           under any fire and extended coverage insurance policy which either
           may have in force at the time of the loss or damage. Tenant shall,
           upon obtaining the policies of insurance required under this Lease,
           give notice to its insurance carrier or carriers that the foregoing
           mutual wavier of subrogation is contained in this Lease.

25.        SUBORDINATION AND ATTORNMENT.

           Upon written request of Landlord, or any mortgage or deed of trust
           beneficiary of Landlord, or ground lessor of Landlord, Tenant shall,
           in writing, subordinate its rights under this Lease to the lien of
           any mortgage or deed of trust, or to the interest of any lease in
           which Landlord is lessee, and to all advances made or hereafter to be
           made thereunder. However, before signing any subordination agreement,
           Tenant shall have the right to obtain from any lender or lessor of
           Landlord requesting such subordination, an agreement in writing
           providing that, as long as Tenant is not in default hereunder, this
           Lease shall remain in effect for the full Lease Term. The holder of
           any security interest may, upon written notice to Tenant, elect to
           have this Lease prior to its security interest regardless of the time
           of the granting or recording of such security interest.

   13
           In the event of any foreclosure sale or transfer in lieu of
           foreclosure, Tenant shall attorn to the purchaser or transferee as
           the case may be, and recognize that party, as Landlord, under this
           Lease, provided such party acquires and accepts the Premises subject
           to this Lease,

26.        TENANT ESTOPPEL CERTIFICATES.

           Within ten (10) days after written request from Landlord, Tenant
           shall execute and deliver to Landlord or Landlord's designee, in
           recordable form, a written statement in the form as required by
           Landlord certifying (a) that this Lease is unmodified and in full
           force and effect, or is in full force and effect as modified and
           stating the modifications; (b) the amount of Annual Base Rent and the
           date to which Annual Base Rent and additional rent have been paid in
           advance; (c) the amount of any security deposited with Landlord; and
           (d) that Landlord is not in default hereunder or, if Landlord is
           claimed to be in default, stating the nature of any claimed default.
           Any such statement may be relied upon by a purchaser, assignee or
           lender. Tenant's failure to execute and deliver such statement within
           the time required shall, at Landlord's election, be a default under
           this Lease without further notice other than that required pursuant
           to Section 28.1 hereof and shall also be conclusive upon Tenant that:
           (1) this Lease is in full force and effect and has not been modified
           except as represented by Landlord; (2) there are no uncured defaults
           in Landlord's performance and that Tenant has no right of offset,
           counterclaim or deduction against Rent; and (3) not more than one
           month's Rent has been paid in advance.

27.        TRANSFER OF LANDLORD'S INTEREST.

           In the event of any sale or transfer by Landlord of the Premises or
           the Project, and assignment of this Lease by Landlord, Landlord shall
           be and is hereby entirely freed and relieved of any and all liability
           and obligations contained in or derived from this Lease arising out
           of any act, occurrence or omission relating to the Premises, Project
           or Lease occurring after the completion of such sale or transfer, and
           Landlord's successor shall be solely responsible for all obligations
           of Landlord under this Lease. If any security deposit or prepaid Rent
           has been paid by Tenant, Landlord may transfer the security deposit
           or prepaid Rent to Landlord's successor and upon such transfer,
           Landlord shall be relieved of any and all further liability with
           respect thereto. Tenant shall fully and properly cooperate in the
           completion of such transfer

28.        DEFAULT.

            28.1. Tenant's Default. The occurrence of any one or more of the
                  following events shall constitute a default and breach of this
                  Lease by Tenant:

                     a.        If Tenant abandons or vacates the Premises; or

                     b.        If Tenant fails to pay any Rent or any additional
                               rent or any other charges required to be paid by
                               Tenant under this Lease and such failure
                               continues for three (3) days after written notice
                               thereof from Landlord (so long as the form of any
                               such notice complies with statutory requirements,
                               any such notice and the opportunity to cure shall
                               be in lieu of and not in addition to the notice
                               required in order to commence unlawful detainer
                               proceedings); or

                     c.        If Tenant fails promptly and fully to perform any
                               non-monetary covenant, condition or agreement
                               contained in this Lease and such failure
                               continues for thirty (30) days after written
                               notice thereof from Landlord to Tenant (so long
                               as the form of any such notice complies with
                               statutory requirements, any such notice and the
                               opportunity to cure shall be in lieu of and not
                               in addition to the notice required in order to
                               commence unlawful detainer proceedings); or

                     d.        If a writ of attachment or execution is levied on
                               this Lease or on any of Tenant's Property; or

                     e.        If Tenant makes a general assignment for the
                               benefit of creditors, or provides for an
                               arrangement, composition, extension or adjustment
                               with its creditors; or

                     f.        If Tenant files a voluntary petition for relief
                               or if a petition against Tenant in a proceeding
                               under the federal bankruptcy laws or other
                               insolvency laws is filed and not withdrawn or
                               dismissed within forty-five (45) days thereafter,
                               or if under the provisions of any law providing
                               for reorganization or winding up of corporations,
                               any court of competent jurisdiction assumes
                               jurisdiction, custody or control of Tenant or any
                               substantial part of its property and such
                               jurisdiction, custody or control remains in force
                               unrelinquished, unstayed or unterminated for a
                               period of forty-five (45) days; or

                     g.        If in any proceeding or action in which Tenant is
                               a party, a trustee, receiver, agent or custodian
                               is appointed to take charge of the Premises or
                               Tenant's Property (or has the authority to do so)
                               for the purpose of enforcing a lien against the
                               Premises or Tenant's Property; or

                     h.        If Tenant is a partnership or consists of more
                               than one person or entry, if any partner of the
                               partnership or other person or entity is involved
                               in any of the acts or events described in
                               subparagraphs (d) through (g) above.

           28.2.     Remedies. In the event of Tenant's default hereunder, then
                     in addition to any other rights or remedies Landlord may
                     have under any law, Landlord shall have the right, at
                     Landlord's option, without further notice or demand of any
                     kind to do the following:

                     a.        Terminate this Lease and Tenant's right to
                               possession of the Premises and reenter the
                               Premises and take possession thereof, and Tenant
                               shall have no further claim to the Premises or no
                               further claim under this Lease; or

   14
                     b.        Maintain Tenant's right to possession, in which
                               case this Lease shall continue in effect whether
                               or not Tenant shall have abandoned the premises.
                               This remedy is intended to be the remedy
                               described in California Civil Code Section
                               1951.4. In such event, Landlord shall be entitled
                               to enforce all of Landlord's rights and remedies
                               under this Lease, including the right to recover
                               the rent as it becomes due hereunder; and/or

                     c.        Reenter the Premises under the provisions of
                               subparagraph (b), and thereafter elect to
                               terminate this Lease and Tenant's right to
                               possession of the Premises.

                     If Landlord reenters the Premises under the provisions of
                     subparagraphs (b) or (c) above, Landlord shall not be
                     deemed to have terminated this Lease or the obligation of
                     Tenant to pay any Rent or other charges thereafter
                     accruing, unless Landlord notifies Tenant in writing of
                     Landlord's election to terminate this Lease. In the event
                     of re-entry or retaking of possession by Landlord, Landlord
                     shall have the right, but not the obligation, to remove all
                     or any part of Tenant's Property in the Premises and to
                     place such property in storage at a public warehouse at the
                     expense and risk of Tenant. If Landlord elects to relet the
                     Premises for the account of Tenant, the rent received by
                     Landlord from such reletting shall be applied as follows:
                     first, to the payment of any indebtedness other than Rent
                     due hereunder from Tenant to Landlord; second, to the
                     payment of any costs of such reletting; third, to the
                     payment of the cost of any alterations or repairs to the
                     Premises; fourth, to the payment of Rent due and unpaid
                     hereunder; and the balance, if any, shall be held by
                     Landlord and applied in payment of future Rent as it
                     becomes due. If that portion of rent received from the
                     reletting which is applied against the Rent due hereunder
                     is less than the amount of the Rent due, Tenant shall pay
                     the deficiency to Landlord within five (5) days after
                     demand by Landlord. Such deficiency shall be calculated and
                     paid monthly. Tenant shall also pay to Landlord, within
                     five (5) days of the demand, any costs and expenses
                     incurred by Landlord in connection with such reletting or
                     in making alterations and repairs to the Premises which are
                     not covered by the rent received from the reletting.

           28.3.     Damages. Should Landlord elect to terminate this Lease
                     under the provisions of subparagraph 28.2(a) or (c) above,
                     Landlord may recover as damages from Tenant the following:

                     a.        Past Rent. The worth at the time of the award of
                               any unpaid Rent which had been earned at the time
                               of termination; plus

                     b.        Rent Prior to Award. The worth at the time of the
                               award of the amount by which the unpaid Rent
                               which would have been earned after termination
                               until the time of award exceeds the amount of
                               such rental loss that Tenant proves could have
                               been reasonably avoided; plus

                     c.        Rent After Award. The worth at the time of the
                               award of the amount by which the unpaid Rent for
                               the balance of the Term after the time of award
                               exceeds the amount of the rental loss that Tenant
                               proves could be reasonably avoided; plus

                     d.        Proximately Caused Damages. Any, other amount
                               necessary to compensate Landlord for all
                               detriment proximately caused by Tenant's failure
                               to perform its obligations under this Lease or
                               which in the ordinary course of things would by
                               likely to result therefrom, including, but not
                               limited to, any costs or expenses (including
                               attorneys' fees), incurred by Landlord in (i)
                               retaking possession of the Premises, (ii)
                               maintaining the Premises after Tenant's default,
                               (iii) preparing the Premises for reletting to a
                               new tenant, including any repairs or alterations,
                               and (iv) reletting the Premises, including
                               brokers' commissions.

                               "The worth at the time of the award" as used in
                               subparagraphs (a) and (b) above, is to be
                               computed by allowing interest on the unpaid rent
                               at the rate of twelve percent (12%) per annum or
                               by allowing interest at the maximum rate an
                               individual is permitted to charge by law,
                               whichever is greater. "The worth at the time of
                               the award" as used in subparagraph (c) above, is
                               to be computed by discounting the amount at the
                               discount rate of the Federal Reserve Bank of San
                               Francisco at the time, of the award plus one
                               percent.

           28.4.     Waiver: Cumulative. The waiver by Landlord of any breach of
                     any term, covenant or condition of this Lease shall not be
                     deemed a waiver of such term, covenant or condition or of
                     any subsequent breach of the same or any other term;
                     covenant or condition. Acceptance of Rent by Landlord
                     subsequent to any breach hereof shall not be deemed to be a
                     waiver of any preceding breach other than the failure to
                     pay the particular Rent so accepted, regardless of
                     Landlord's knowledge of any breach at the time of such
                     acceptance of Rent. Landlord shall not be deemed to have
                     waived any term, covenant or condition unless Landlord
                     gives Tenant written notice of such waiver. Landlord's
                     exercise of any right of remedy shall not prevent it from
                     exercising any other right or remedy which may be provided

                     g.        No writ of execution will ever be levied against
                               the assets of any partner of Landlord; and

                     h.        These covenants and agreements are for the
                               benefit of and shall be enforceable both by

           the Premises forms a part, at Landlord's sole cost and expense, and
           the terms and conditions of the original Lease shall remain in full

                               endorsement or statement on any check or letter
                               accompanying any check or payment as Rent, be
                               deemed an accord and satisfaction, and Landlord
                               may accept such check or payment without
                               prejudice to Landlord's right to recover the
                               balance of the Rent or pursue any other remedy
                               provided for in this Lease. In connection with

                     b.        Addenda. If any provision contained in an
                               addendum to this Lease is inconsistent with any
                               other provision herein, the provision contained
                               in the addendum shall control, unless otherwise

                               prevailing party shall be entitled to recover all
                               costs and expenses, including reasonable

                               action or proceeding. In addition, if Landlord
                               incurs attorneys fees and/or costs in enforcing
                               or seeking to enforce any right of indemnity set
                               forth in the Lease, all such attorneys' fees and
                               costs shall be recoverable and deemed within the
                               scope of such indemnity and/or this attorneys'
                               fees provisions.

                               requested.

                               of any consent, approval or statement of
                               satisfaction, and in such event, Tenant's only

                               The party requesting that a short form lease be
                               recorded shall be responsible for paying any
                               costs incurred in connection therewith.

                     o.        Severability. A final determination by a court of
                               competent jurisdiction that any provision of this
                               Lease is invalid shall not affect the validity of
                               any other provision, and any provision so
                               determined to be invalid shall to the extent
                               possible, be construed to accomplish its intended
                               effect.

                     p.        Successors and Assigns. This Lease shall apply to
                               and bind the permitted successors and assigns of
                               the parties.

                     q.        Time of the Essence. Time is of the essence in
                               this Lease.

                     r.        Waiver. No delay or omission in the exercise of
                               any right or remedy of Landlord upon any default
                               by Tenant shall impair such right or remedy or be
                               construed as a waiver of such default.

                               The receipt and acceptance by Landlord of
                               delinquent Rent shall not constitute a waiver of
                               any other default: it shall constitute only a
                               waiver of timely payment for the particular Rent
                               payment involved.

                               No act or conduct of Landlord including, without
                               limitation, the acceptance of keys to the
                               Premises, shall constitute an acceptance of the
                               surrender of the Premises by Tenant before the
                               expiration of the Term. Only a written notice
                               from Landlord to Tenant shall constitute
                               acceptance of the surrender of the Premises and
                               accomplish a termination of the Lease.

                               Landlord's consent to or approval of any act by
                               Tenant requiring Landlord's consent or approval
                               shall not be deemed to waive or render
                               unnecessary Landlord's consent to or approval of
                               any subsequent act by Tenant.

                               Any waiver by Landlord of any default must be in
                               writing and shall not be a waiver of any other
                               default concerning the same or any other
                               provision of the Lease.

                     s.        Mortgagee Protection. In the event of any default
                               on the part of Landlord, Tenant will give notice
                               by registered or certified mail to any
                               beneficiary of a deed of trust or mortgage
                               covering the Premises whose address shall have
                               been furnished to Tenant, and shall offer such
                               beneficiary of mortgagee a reasonable opportunity
                               to cure the default, including time to obtain
                               possession of the Premises by power of sale or a
                               judicial foreclosure, if such should prove
                               necessary to effect a cure.

                     t.        Identification of Tenant. If more than one person
                               executes this Lease as Tenant:

                               (i)        Each of them is jointly and severally
                                          liable for the keeping, observing and

                                          covenants, conditions, provisions and

                                          observed and performed by Tenant, and

                               (ii)       The term "Tenant" as used in this
                                          Lease shall mean and include each of
                                          them jointly and severally. The act of
                                          or notice from or notice or refund to,
                                          or the signature of any one or more of
                                          them, with respect to the tenancy of
                                          this Lease, including, but not limited
                                          to any renewal, extension, expiration,
                                          termination or modification of this
                                          Lease, shall be binding upon each and
                                          all of the persons executing this
                                          Lease as Tenant with the same force
                                          and effect as if each and all of them
                                          had so acted or so given or received
                                          such notice or refund or so signed.

                     u.        Exhibits and Addenda. All exhibits and addenda

                               this reference and shall be deemed a part of this

                     Notwithstanding anything to the contrary contained herein,
                     the obligations of Tenant hereunder shall not extend beyond
