2.       PREMISES. Landlord leases to Tenant the premises described in section 1
         and in Exhibit A (the "Premises"), located in this project described on
         Exhibit B (the "Project"). By entry on the Premises, Tenant
         acknowledges that it has examined the Premises and accepts the Premises
         in their present condition, subject to any additional work Landlord has
         agreed to do. Tenant represents and warrants that it agrees with the
         square footage specified for the Premises in Section 1 and will not
         hereafter challenge such determination and agreement.

3.       TERM. The term of this lease is for the period set forth in Section 1,
         commencing on the date in Section 1. If Landlord, for any reason,
         cannot deliver possession of the Premises to Tenant upon commencement
         of the term, this Lease shall not be void or voidable, nor shall
         Landlord be liable to Tenant for any loss or damage resulting from such
         delay. In that event, however, there shall be a rent abatement covering
         the period between the commencement of the term and the time when
         Landlord delivers possession to Tenant,


                                       2
   3
         and all other terms and conditions of this Lease shall remain in full
         force and effect, provided, however, that if Landlord cannot deliver
         possession of the Premises to Tenant, this Lease shall be void. If a
         delay in possession is caused by Tenant's failure to perform any
         obligation in accordance with this Lease, the term shall commence as
         set forth in Section 1 and there shall be no reduction of rent between
         the commencement of the term and the time Tenant takes possession.

4.       RENT

         a.       BASE RENT. Tenant shall pay Landlord monthly base rent in the
                  initial amount in Section 1 which shall be payable monthly in
                  advance on the first day of each and every calendar month
                  ("Base Monthly Rent") provided, however, the first month's
                  rent is due and payable upon execution of this Lease. If the
                  term of this Lease contains any rental abatement period,
                  Tenant hereby agrees that if Tenant breaches the Lease and/or
                  abandons the Premises before the end of the Lease term, or if
                  Tenant's right to possession is terminated by Landlord because
                  of Tenant's breach of the Lease, Landlord shall, at its
                  option, (1) void the rental abatement period; and (2) recover
                  from tenant, in addition to any damages due Landlord under the
                  terms and conditions of the Lease, rent prorated for the
                  entirety of the rental abatement period at a rental rate
                  equivalent to two (2) times the Base Monthly rent.

                  For purposes of Section 467 of the Internal Revenue Code, the
                  parties to this Lease hereby agree to allocate the stated
                  rents, provided herein, to the periods which correspond to the
                  actual rent payment as provided under the terms and conditions
                  of this agreement.

         b.       RENT ADJUSTMENT.

                  (1)      COST OF LIVING ADJUSTMENT. If Section 1.i(1) is
                           initialed, the Base Monthly Rent shall be subject to
                           increase on each annual anniversary of the
                           commencement of the terms of this Lease. The base for
                           computing the increase is the Consumer Price Index
                           All Urban Consumers U.S. City Average (1982-84=100),
                           published by the United States Department of Labor,
                           Bureau of Labor Statistics ("Index"), which is in
                           effect on the ninetieth (90th) day preceding the date
                           of the commencement of the term ("Beginning Index").
                           The index published and in effect on the ninetieth
                           (90th) day preceding each anniversary of the
                           commencement of the term of this Lease ("Extension
                           Index") is to be used in determining the amount of
                           the increase from one year to the next. Beginning
                           with the rent due on and after the first anniversary
                           of the Commencement Date, the Base Monthly Rent due
                           with respect to the month immediately preceding such
                           anniversary date by a fraction. On the first
                           anniversary of the Commencement Date, the numerator
                           of the fraction will be the Extension Index and the
                           denominator will be the Beginning Index. On the
                           second



                                       3
   4
                           and any subsequent anniversaries of the Commencement
                           Date, the numerator of the fraction will be the
                           current Extension Index and the denominator will be
                           the Extension Index used to calculate the previous
                           year's rental increase. If there is a decline from
                           one lease year to the next in the Extension Index,
                           the monthly rent due during the subsequent lease year
                           shall equal the monthly rent due during the then
                           present lease year.

                           If the Index is changed so that the base year differs
                           from that in effect when the term commences, the
                           Index shall be converted in accordance with the
                           conversion factor published by the United States
                           Department of Labor, Bureau of Labor Statistics. If
                           the Index is discontinued or revised during the term,
                           such other government index or computation with which
                           it is replaced shall be used in order to obtain
                           substantially the same result as would be obtained if
                           the Index had not been discontinued or revised.

                  (2)      STEP INCREASE. If Section 1.i.(2) is initialed, Base
                           Monthly Rent shall be increased periodically to the
                           amounts and at the times set forth in Section
                           1.i.(2).

         c.       EXPENSES. The purpose of this Section 4.c is to ensure that
                  Tenant bears a share of all Expenses related to the use,
                  maintenance, ownership, repair or replacement and insurance of
                  the Project. Accordingly, beginning on the date Tenant takes
                  possession of the Premises, Tenant shall pay to Landlord
                  Tenant's Share (as defined below) of Expenses related to the
                  Project.

                  (1)      EXPENSES DEFINED. The term "Expenses" shall mean all
                           costs and expenses of the ownership, operation,
                           maintenance, repair or replacement, and insurance of
                           the Project, including without limitation, the
                           following costs:

                           (a)      All supplies, materials, labor, equipment,
                                    and utilities used in or related to the
                                    operation and maintenance of the Project;

                           (b)      All maintenance, management, janitorial,
                                    legal, accounting, insurance, and service

                           (c)      All maintenance, replacement and repair

                                    air conditioning systems, sidewalks,
                                    landscaping, service areas, driveways,
                                    parking areas (including resurfacing and
                                    restriping parking areas), walkways,
                                    building exteriors (including painting),
                                    signs and directories, repairing and

                                    be included either based on actual
                                    expenditures or the use of an accounting
                                    reserve based on past cost experience for
                                    the Project.

                           (d)      Amortization (along with reasonable
                                    financing charges) of capital improvements
                                    made to the Project which may be required by
                                    any government authority or which will
                                    improve the operating efficiency of the
                                    Project (provided, however, that the amount
                                    of such amortization for improvements not
                                    mandated by government authority shall not
                                    exceed in any year the amount of costs
                                    reasonably determined by Landlord in its
                                    sole discretion to have been saved by the
                                    expenditure either through the reduction or
                                    minimization of increases which would have
                                    otherwise occurred).

                           (e)      Real Property Taxes including all taxes,
                                    assessments (general and special) and other
                                    impositions or charges which may be taxed,
                                    charged, levied, assessed or imposed upon
                                    all or any portion of or in relation to the

                                    increase caused by the transfer, sale or
                                    encumbrance of the Project or any portion
                                    thereof. "Real Property Taxes" shall also
                                    include any form of assessment, levy,
                                    penalty, charge or tax (other than estate,
                                    inheritance, net income, or franchise taxes)
                                    imposed by any authority having a direct or
                                    indirect power to tax or charge, including,
                                    without limitation, any city, county, state
                                    federal or any improvement or other
                                    district, whether such tax is (1) determined
                                    by the value of the Project or the rent or
                                    other sums payable under this Lease; (2)
                                    upon or with respect to any legal or

                                    transaction or any document to which Tenant
                                    is a party creating a transfer in any
                                    interest in the Project; (4) in lieu of or
                                    as a direct substitute in whole or in part
                                    of or in addition to any real property taxes
                                    on the Project; (5) based on any parking
                                    spaces or parking facilities provided in the

                                    services, such as police protection, fire
                                    protection, street, sidewalk and roadway
                                    maintenance, refuse removal or other
                                    services that may be provided by any
                                    governmental or quasi-governmental agency
                                    from time to time which were formerly
                                    provided without charge or with less charge
                                    to property owners or occupants.

                           (f)      All costs and expenses of improvements,
                                    alterations, modifications, additions and
                                    changes to the Project, or any portion
                                    thereof, necessary to bring the Project into
                                    full compliance with all federal, state or
                                    local statutes, rules, regulations or
                                    ordinances regarding handicapped
                                    accessibility and use, now in existence or
                                    arising in the future, including but not
                                    limited to the provisions of the Americans
                                    With Disabilities Act, 42 U.S.C.
                                    Sections 12101, et. seq., as may be
                                    amended from time to time.

                  (2)      ANNUAL ESTIMATE OF EXPENSES; TENANT'S SHARE. When
                           Tenant takes possession of the Premises, Landlord
                           shall estimate Tenant's share of Expenses for the
                           remainder of the calendar year, and at the
                           commencement of each calendar year thereafter,
                           Landlord shall estimate Tenant's Share of Expenses
                           for the coming year by multiplying the estimated per
                           square foot annual Project Expenses by the Premises
                           area.

                  (3)      MONTHLY PAYMENT OF EXPENSES. Tenant shall pay to
                           Landlord, monthly in advance, as additional rent,
                           one-twelfth (1/12) of the Annual Estimate of Expenses
                           beginning on the date Tenant takes possession of the
                           Premises. As soon as practical following each
                           calendar year, Landlord shall prepare an accounting
                           of actual Expenses incurred during the prior calendar
                           year and such accounting shall reflect Tenant's Share
                           of Expenses. If the additional rent paid by Tenant
                           under this Section 4.c.3 during the preceding
                           calendar year was less than the actual amount of
                           Tenant's Share of Expenses, Landlord shall so notify
                           Tenant and Tenant shall pay such amount to Landlord
                           within 30 days of receipt of such notice. Such amount
                           shall be deemed to have accrued during the prior
                           calendar year and shall be due and payable from
                           Tenant even though the term of this Lease has expired
                           or this lease has been terminated prior to Tenant's
                           receipt of this notice. Tenant shall have thirty (30)
                           days from receipt of such notice to contest the
                           amount due; failure to so notify Landlord shall
                           represent final determination of Tenant's Share of
                           expenses. If Tenant's payments were greater than the
                           actual amount, then such overpayment shall be
                           credited by Landlord to all present rent due under
                           this Section 4.c.3.

         d.       RENT WITHOUT OFFSET AND LATE CHARGE. All rent shall be paid by
                  Tenant to Landlord monthly in advance on the first day of
                  every calendar month, at the address shown in Section 1, or
                  such other place as landlord may designate in writing from
                  time to time. All rent shall be paid without prior demand or
                  notice and without any deduction or offset whatsoever. All
                  rent shall be paid in lawful currency of the United States of
                  America. Proration of rent due for any partial month shall be
                  calculated by dividing the number of days in the month for
                  which rent is due by the actual number of days in that month
                  and multiplying by the applicable monthly rate. Tenant
                  acknowledges that late payment by Tenant to Landlord of any
                  rent or other sums due under this Lease will cause Landlord to
                  incur costs not contemplated by this Lease, the exact amount
                  of such cost being extremely difficult and impracticable to
                  ascertain. Such costs include, without limitation, processing
                  and accounting charges and late charges that may be imposed on
                  Landlord by the terms of any encumbrance or note secured by
                  the Premises. Therefore, if any rent or other sum due from
                  Tenant is not received when due, Tenant shall pay to Landlord
                  an additional sum equal to 10% of such overdue payment.
                  Landlord and Tenant hereby agree that such late charge
                  represents a fair and reasonable estimate of the costs that
                  Landlord will incur by


                                       6
   7
                  reason of any such late payment and that the late charge is in
                  addition to any and all remedies available to the Landlord and
                  that the assessment and/or collection of the late charge shall
                  not be deemed a waiver of any other default. Additionally, all
                  such delinquent rent or other sums, plus this late charge,
                  shall bear interest at the rate of 18 percent per annum. If
                  the interest rate specified in this Lease is higher than the
                  rate permitted by law, the interest rate is hereby decreased
                  to the maximum legal interest rate permitted by law. Any
                  payments of any kind returned for insufficient funds will be
                  subject to an additional handling charge of $25.00, and
                  thereafter, Landlord may require Tenant to pay all future
                  payments of rent or other sums due by money order or cashier's
                  check.

5.       PREPAID RENT. Upon the execution of this Lease, Tenant shall pay to
         landlord the prepaid rent set forth in Section 1, and if Tenant is not
         in default of any provisions of this Lease, such prepaid rent shall be
         applied toward the rent due for the first month of the term. Landlord's
         obligations with respect to the prepaid rent are those of a debtor and
         not of a trustee, and Landlord can commingle the prepaid rent with
         Landlord's general funds. Landlord shall not be required to pay Tenant
         interest on the prepaid rent. Landlord shall be entitled to immediately
         endorse and cash Tenant's prepaid rent; however, such endorsement and
         cashing shall not constitute Landlord's acceptance of this Lease. In
         the event Landlord does not accept this Lease, Landlord shall return
         said prepaid rent.

6.       DEPOSIT. Upon execution of this Lease, Tenant shall deposit a security
         deposit and a cleaning fee as set forth in Section 1 with Landlord. If
         Tenant is in default, Landlord can use the security deposit or any
         portion of it to cure the default or to compensate Landlord for any
         damages sustained by Landlord resulting from Tenant's default. Upon
         demand, Tenant shall immediately pay to Landlord a sum equal to the
         portion of the security deposit expended or applied by Landlord to
         restore the security deposit to its full amount. In no event will
         Tenant have the right to apply any part of the security deposit to any
         rent or other sums due under this Lease. If Tenant is not in default at
         the expiration or termination of this Lease, Landlord shall return the
         security deposit to Tenant, and retain the cleaning fee, which shall
         equal 10% of the first month's rent or $125, whichever is greater.
         Landlord's obligations with respect to the deposit are those of a
         debtor and not of a trustee, and Landlord can commingle the security
         deposit with Landlord's general funds. Landlord shall not be required
         to pay Tenant interest on the deposit. Landlord shall be entitled to
         immediately endorse and cash Tenant's prepaid deposit, however, such
         endorsement and cashing shall not constitute Landlord's acceptance of
         this Lease. In the event Landlord does not accept this Lease, Landlord
         shall return said prepaid deposit. Each time the Base Rent is
         increased, Tenant shall deposit additional funds with Landlord
         sufficient to increase the security to an amount which bears the same
         relationship to the adjusted Base Rent as the initial security deposit
         bore to the initial Base Rent.

7.       USE OF PREMISES AND PROJECT FACILITIES. Tenant shall use the Premises
         solely for the purposes set forth in Section 1 and for no other purpose
         without obtaining the prior written consent of Landlord. Tenant
         acknowledges that neither Landlord nor any agent of


                                       7
   8
         Landlord has made any representation or warranty with respect to the
         Premises or with respect to the suitability of the Premises or the
         Project for the conduct of Tenant's business, nor has Landlord agreed
         to undertake any modification, alteration or improvement to the
         Premises or the Project, except as provided in writing in this Lease.
         Tenant acknowledges that Landlord may from time to time, at its sole
         discretion, make such modifications, alterations, deletions or
         improvements to the Project as Landlord may deem necessary or
         desirable, without compensation or notice to Tenant. Tenant shall
         promptly comply with all laws, ordinances, orders and regulations
         affecting the Premises and the Project, including, without limitation,
         any rules and regulations that may be attached to this Lease and to any
         reasonable modifications to these rules and regulations as Landlord may
         adopt from time to time. Tenant shall not do or permit anything to be
         done in or about the Premises or bring or keep anything in the Premises
         that will in any way increase the premiums paid by Landlord on its
         insurance related to the Project or which will in any way increase the
         premiums for fire or casualty insurance carried by other tenants in the
         Project. Tenant will not perform any act or carry on any practices that
         may injure the Premises or the Project; that may be a nuisance or
         menace to other tenants in the Project; or that shall in any way
         interfere with the quiet enjoyment of such other tenants. Tenant shall
         not use the Premises for sleeping, washing clothes, cooking or the
         preparation, manufacture or mixing of anything that might emit any
         objectionable odor, noises, vibrations or lights onto such other
         tenants. If sound insulation is required to muffle noise produced by
         Tenant on the Premises, Tenant at its own cost shall provide all
         necessary insulation. Tenant shall not do anything on the premises
         which will overload any existing parking or service to the Premises.
         Pets and/or animals of any type shall not be kept on the Premises.

8.       EMISSION, USE AND DISPOSAL OF WASTE AND TOXIC MATERIALS.

         a.       EMISSIONS. Tenant shall not:

                  (1)      Permit any vehicle on the premises to emit exhaust
                           which is in violation of any governmental law, rule,
                           regulation or requirement;

                  (2)      Produce, or permit to be produced, any intense glare,

                           light or heat shall not be discernible from outside
                           the Premises;

                  (3)      Create, or permit to be created, any sound pressure
                           level which will interfere with the quiet enjoyment
                           of any real property outside the Premises, or which
                           will create a nuisance or violate any governmental
                           law, rule, regulation or requirement;

                  (4)      Create, or permit to be created, any ground vibration

   9
                  (5)      Transmit, receive or permit to be transmitted or
                           received, any electromagnetic, microwave or other
                           radiation which is harmful or hazardous to any person
                           or property in, or about the Premises, or anywhere
                           else.

         b.       DISPOSAL OF WASTE

                  (1)      Non-Toxic Refuse Disposal. Tenant shall not keep any
                           non-toxic trash, garbage waste or other refuse on the
                           Premises except in sanitary containers and shall
                           regularly and frequently remove same from the
                           Premises. Tenant shall keep all incinerators,
                           containers or other equipment used for storage or
                           disposal of such materials in a clean and sanitary
                           condition.

                  (2)      Sewage Disposal. Tenant shall properly dispose of all
                           sanitary sewage and shall not use the sewage disposal
                           system (a) for the disposal of anything except
                           sanitary sewage or (b) excess of the lesser amount
                           (i) reasonably contemplated by the uses permitted
                           under this Lease or (ii) permitted by any
                           governmental entity. Tenant shall keep the sewage
                           disposal system free of all obstructions and in good
                           operating condition.

                  (3)      Disposal of Other Non-Toxic Waste. Tenant shall
                           properly dispose of all other waste or other matter

                           used on, or removed from, the Premises in such a
                           manner that it does not, and will not, adversely
                           affect the (a) health or safety of persons, wherever
                           located, whether on the Premises or elsewhere (b)
                           condition, use or enjoyment of the Premises or any
                           other real or personal property, wherever located,
                           whether on the Premises or anywhere else, or (c)
                           Premises or any of the improvements thereto or
                           thereon including buildings, foundations, pipes,
                           utility lines, landscaping or parking areas.

         c.       INFORMATION. If Landlord consents to Tenant's storage or use
                  of toxic materials on the Premises as set forth in Paragraph

         d.       TOXIC MATERIALS.

                  (1)      DEFINITIONS.

                           (a)      As used in this Lease, the term "Hazardous
                                    Material(s)" means any oil, flammable items,

         elects, at its own cost Tenant shall restore the Premises to the
         condition designated by Landlord in its election, before the last day
         of the term or within 30 days after notice of its election is given,
         whichever is later.

         Should Landlord consent in writing to Tenant's alteration of the
         Premises, Tenant shall contract with a contractor approved by Landlord
         for the construction of such alterations, shall secure all appropriate
         governmental approvals and permits, and shall complete such alterations
         with due diligence in compliance with plans and specifications approved
         by Landlord. All such construction shall be performed in a manner which
         will not interfere with the quiet enjoyment of other tenants of the
         Project. Tenant shall pay all costs for such construction and shall
         keep the Premises and the Project free and clear of all mechanics'
         liens which may result from construction by Tenant.

15.      RELEASE AND INDEMNITY. As material consideration to Landlord, Tenant
         agrees that Landlord shall not be liable to Tenant for any damage to
         Tenant or tenant's property from any cause and Tenant waives all claims
         against Landlord for damage to persons or property arising for any
         reason, except for damage resulting directly from Landlord's breach of
         its express obligations under this Lease which Landlord has not cured
         within a reasonable time after receipt of written notice of such breach
         from Tenant. Tenant shall indemnify and hold Landlord harmless from all
         damages arising out of any damage to any person or property occurring
         in, or about the Premises or Tenant's use of the Premises or Tenant's
         breach of any term of this Lease.

16.      INSURANCE. Tenant, at its cost, shall maintain public liability and
         property damage insurance and products liability insurance with a
         single combined liability limit of $1,000,000, insuring against all
         liability of Tenant and its representatives, employees. invitees, and
         agents arising out of or in connection with Tenant's use or occupancy
         of the Premises. Public liability insurance, products liability
         insurance and property damage insurance shall insure performance by
         Tenant of the indemnity provisions of Section 15. Landlord and
         Landlord's designated manager shall be named as additional insured and
         the policy shall contain cross-liability endorsements. On all its
         personal property, at its cost, Tenant shall maintain a policy of
         standard fire and extended coverage insurance with vandalism and
         malicious mischief endorsements and "all risk" coverage on all Tenant's
         improvements and alterations, including without limitation, all items
         of Tenant responsibility described in Section 13 or in or about the
         Premises, to the extent of at least 90% of their full replacement
         value. The proceeds from any such policy shall be used by Tenant for
         the replacement of personal property and the restoration of Tenants
         improvements or alterations. All insurance required to be provided by
         Tenant under this Lease shall release Landlord from any claims for
         damage to any person or the Premises and the Project, and to Tenant's
         fixtures, personal property, improvements and alterations in or on the
         Premises or the Project, caused by or resulting from risks insured
         against under any insurance policy carried by Tenant in force at the
         time of such damage. All insurance required to be provided by Tenant
         under this Lease: (a) shall be issued by


                                       14
   15
         insurance companies authorized to do business in the state in which the
         premises are located with a financial rating of at least an A+XII
         status as rated in the most recent edition of Best's Insurance Reports;
         (b) shall be issued as a primary policy; and (c) shall contain an
         endorsement requiring at least 30 days prior written notice of
         cancellation to Landlord and Landlord's lender, before cancellation or
         change in coverage, scope or amount of any policy. Tenant shall deliver
         a certificate or copy of such policy together with evidence of payment
         of all current premiums to Landlord prior to the Commencement Date of
         this Lease. Tenant's failure to provide evidence of such coverage to
         Landlord may, in Landlord's sole discretion, constitute a default under
         this Lease.

17.      DESTRUCTION. If during the term, the Premises or Project are more than
         10% destroyed from any cause, or rendered inaccessible or unusable from
         any cause, Landlord may, in its sole discretion, terminate this Lease
         by delivery of notice to Tenant within 30 days of such event without
         compensation to Tenant. If in Landlord's estimation, the Premises
         cannot be restored within 90 days following such destruction, the
         Landlord shall notify Tenant and Tenant may terminate this Lease by
         delivery of notice to Landlord within 30 days of receipt of Landlord's
         notice. If Landlord does not terminate this Lease and if in Landlord's
         estimation the Premises can be restored within 90 days, then Landlord
         shall commence to restore the Premises in compliance with then existing
         laws and shall complete such restoration with due diligence. In such
         event, this Lease shall remain in full force and effect, but there
         shall be an abatement of rent between the date of destruction and the
         date of completion of restoration, based on the extent to which
         destruction interferes with Tenant's use of the Premises.

18.      CONDEMNATION.

         a.       DEFINITIONS. The following definitions shall apply: (1)
                  "Condemnation" means (a) the exercise of any governmental
                  power of eminent domain, whether by legal proceedings or
                  otherwise by condemnor and (b) the voluntary sale or transfer
                  by Landlord to any condemnor either under threat of
                  condemnation or while legal proceedings for condemnation are
                  proceeding; (2) "Date of Taking" mans the date the condemnor
                  has right to possession of the property being condemned; (3)
                  "Award" means all compensation, sums or anything of value
                  awarded, paid or received on a total or partial condemnation;
                  and (4) "Condemnor' means any public or quasi-public
                  authority, or private corporation or individual, having power
                  of condemnation.

         b.       OBLIGATIONS TO BE GOVERNED BY LEASE. If during the term of the
                  Lease there is any taking of all or any part of the Premises
                  or the Project, the rights and obligations of the parties
                  shall be determined pursuant to this Lease.

         c.       TOTAL OR PARTIAL TAKING. If the Premises are totally taken by
                  condemnation, this Lease shall terminate on the date of
                  taking. If any portion of the Premises is taken by
                  condemnation, this Lease shall remain in effect, except that
                  Tenant can elect to


                                       15
   16
                  terminate this Lease if the remaining portion of the Premises
                  is rendered unsuitable for Tenant's continued use of Premises.
                  If Tenant elects to terminate this Lease, Tenant must exercise
                  its right to terminate by giving notice to Landlord within 30
                  days after the nature and extent of the taking have been
                  finally determined. If Tenant elects to terminate this Lease,
                  Tenant shall also notify Landlord of the date of termination,
                  which date shall not be earlier than 30 days nor later than 90
                  days after Tenant has notified Landlord of its election to
                  terminate; except that this Lease shall terminate on the date
                  of taking if the date of taking falls on a date before the
                  date of termination as designated by Tenant. If any portion of
                  the Premises is taken by condemnation and this Lease remains
                  in full force and effect, on the date of taking the rent shall
                  be reduced by an amount in the same ratio as the total number
                  of square feet in the Premises taken bears to the total number
                  of square feet in the Premises immediately before the date of
                  taking.

19.      ASSIGNMENT OR SUBLEASE. Tenant shall not assign or encumber its
         interest in this Lease or the Premises or sublease all or any part of
         the Premises or allow any other person or entity (except Tenant's
         authorized representatives, employees, invitees, or guests) to occupy
         or use all or any part of the Premises without first obtaining
         Landlord's reasonable consent which Landlord may withhold or condition
         in its sole discretion. Any assignment, encumbrance or sublease without
         Landlord's written consent shall be voidable and at Landlord's
         election, shall constitute a default. If Tenant is a partnership, a
         withdrawal or change, voluntary, involuntary or by operation of law of
         any partner, or the dissolution of the partnership, shall be deemed a
         voluntary assignment. If Tenant consists of more than one person, a
         purported assignment, voluntary or involuntary or by operation of law
         from one person to the other shall be deemed a voluntary assignment. If
         Tenant is a corporation, any dissolution, merger, consolidation or
         other reorganization of Tenant, or sale or other transfer of a
         controlling percentage of the capital stock of Tenant, or the sale of
         at least 50% of the value of the assets of Tenant shall be deemed a
         voluntary assignment. The phrase "controlling percentage" means
         ownership of and right to vote stock possessing at least 50% of the
         total combined voting power of all classes of Tenant's capital stock
         issued, outstanding and entitled to vote for election of directors.
         This Section 19 shall not apply to corporations the stock of which is
         traded through an exchange or over the counter. All rent received by
         Tenant from its subtenants in excess of the rent payable by Tenant to
         Landlord under this Lease shall be paid to Landlord, or any sums to be
         paid by an assignee to Tenant in consideration of the assignment of
         this Lease shall be paid to Landlord. If Tenant requests Landlord to
         consent to a proposed assignment or subletting, Tenant shall pay to
         Landlord, whether or not consent is ultimately given, $100 or
         Landlord's reasonable attorney's fees incurred in connection with such
         request, whichever is greater.

         No interest of Tenant in this Lease shall be assignable by involuntary
         assignment through operation of law (including without limitation the
         transfer of this Lease by testacy or intestacy). Each of the following
         acts shall be considered an involuntary assignment: (a) if Tenant is or
         becomes bankrupt or insolvent, makes an assignment for the benefit of


                                       16
   17
         creditors, or institutes proceedings under the Bankruptcy Act in which
         Tenant is the bankrupt; or it Tenant is a partnership or consists of
         more than one person or entity, if any partner of the partnership or
         other person or entity is or becomes bankrupt or insolvent, or makes an
         assignment for the benefit of creditors; or (b) if a writ of attachment
         or execution is levied on this Lease; or (c) if in any proceeding or
         action to which Tenant is a party, a receiver is appointed with
         authority to take possession of the Premises An involuntary assignment
         shall constitute a default by Tenant and Landlord shall have the right
         to elect to terminate this Lease, in which case this Lease shall not be
         treated as an asset of Tenant.

20.      DEFAULT. The following events shall constitute a default by Tenant
         under this Lease:

         a.       a default by Tenant in the payment when due of any rent or
                  other sum payable hereunder,

         b.       a default by Tenant in the performance of any of the other
                  terms, covenants, agreements or conditions contained herein;

         c.       the bankruptcy or insolvency of Tenant, transfer by Tenant in
                  fraud of creditors, an assignment by Tenant for the benefit of
                  creditors, or the commencement of any proceedings of any kind
                  by or against Tenant under any provision of the Federal
                  Bankruptcy Act or under any other insolvency, bankruptcy or
                  reorganization act unless, in the event such proceedings are
                  involuntary, Tenant is discharged from same within sixty (60)
                  days thereafter,

         d.       the appointment of a receiver for a substantial part of the
                  assets of Tenant;

         e.       the abandonment of the Premises (failure to occupy and operate
                  the Premises for ten (10) consecutive days shall be deemed an
                  abandonment); and

         f.       the levy upon this Lease or any estate of Tenant hereunder by
                  any attachment or execution and the failure to have such
                  attachment or execution vacated within thirty (30) days
                  thereafter.

21.      LANDLORD'S REMEDIES. Landlord shall have the following remedies if
         Tenant is in default (These remedies are not exclusive; they are
         cumulative and in addition to any remedies now or late allowed by law):
         Landlord may terminate Tenant's right to possession of the Premises at
         any time. No act by Landlord other than giving notice to Tenant shall
         terminate this Lease. Acts of maintenance, efforts to relet the
         Premises, or the appointment of a receiver on Landlord's initiative to
         protect Landlord's interest under this Lease shall not constitute a
         termination of Tenant's right to possession. Upon termination of
         Tenant's right to possession, Landlord has the right to recover from
         Tenant (1) the worth of the unpaid rent that had been earned at the
         time of termination of Tenant's right to possession; (2) the worth of
         the amount of the unpaid rent that would have been earned after the
         date of termination of Tenant's right to possession; (3) any other
         amount, including but not limited to, expenses incurred to relet the
         premises, court,


                                       17
   18
         attorney and collection costs, necessary to compensate Landlord for all
         detriment caused by Tenant's default. "The Worth," as used for Item
         21(l) in this Paragraph 21 is to be computed by allowing interest at
         the rate of 18 percent per annum. If the interest rate specified in
         this Lease is higher than the rate permitted by law, the interest rate
         is hereby decreased to the maximum legal interest rate permitted by
         law. "The Worth" as used for Item 21(2) in this Paragraph 21 is to be
         computed by discounting the amount at the discount rate of the Federal
         Reserve Bank of San Francisco at the time of termination of Tenant's
         right of possession.

         In the event of any default by Tenant, Landlord shall also have the
         right, with or without terminating this Lease, to reenter the Premises
         and remove all persons, and property from the Premises. Such property
         may be removed and stored in a public warehouse or elsewhere at the
         cost of and for the account of Tenant. No reentry or taking possession
         of the Premises by Landlord pursuant to this Paragraph 21 shall be
         construed as an election to terminate this Lease unless a written
         notice of such intention is given to Tenant or unless the termination
         thereof is decreed by a court of competent jurisdiction.

         In the event of the vacation or abandonment of the Premises by Tenant,
         or in the event that Landlord shall elect to reenter as provided above
         or shall take possession of the Premises pursuant to legal proceeding
         or pursuant to any notice provided by law, then if Landlord does not
         elect to terminate this Lease as provided above, Landlord may from time
         to time, without terminating this Lease, either recover all rent as it
         becomes due or relet the Premises or any part thereof for the term of
         this Lease on terms and conditions as Landlord in its sole discretion
         may deem advisable with the right to make alterations and repairs to
         the Premises.

22.      ENTRY ON PREMISES. Landlord and its authorized representatives shall
         have the right to enter the Premises at all reasonable times for any of
         the following purposes: (a) to determine whether the Premises are in
         good condition and whether Tenant is complying with its obligations
         under this Lease; (b) to do any necessary maintenance and to make any
         restoration to the Premises or the Project that Landlord has the right
         or obligation to perform; (c) to post "for sale" signs at any time
         during the term, to post "for rent" or "for lease" signs during the
         last 90 days of the term, or during any period while Tenant is in
         default; (d) to show the Premises to prospective brokers, agents,
         buyers, tenants or persons interested in leasing or purchasing the
         Premises, at any time during the term; or (e) to repair, maintain or
         improve the Project and to erect scaffolding and protective barricades
         around and about the Premises but not so as to prevent entry to the
         Premises and to do any other act or thing necessary for the safety or
         preservation of the Premises or the Project. Landlord shall not be
         liable in any manner for an any inconvenience, disturbance, loss of
         business, nuisance or other damage arising out of Landlord's entry onto
         the Premises as provided in this Section 22. Tenant shall not be
         entitled to an abatement or reduction of rent if Landlord exercises any
         rights reserved in this Section 22. Landlord shall conduct his
         activities on the Premises as provided herein in a manner that will
         cause the least inconvenience, annoyance or disturbance to Tenant. For
         each of these purposes, Landlord shall at all times have and retain a
         key with which to unlock all


                                       18
   19
         the doors, in, upon and about the Premises, excluding Tenant's vaults
         and safes. Tenant shall not alter any lock or install a new or
         additional lock or bolt on any door of the Premises without prior
         written consent of Landlord. If Landlord gives its consent, Tenant
         shall furnish Landlord with a key for any such lock.

23.      SUBORDINATION. Without the necessity of any additional document being
         executed by Tenant for the purpose of effecting a subordination, and at
         the election of Landlord or any mortgagee or any beneficiary of a Deed
         of Trust with a lien on the Project or any ground lessor with respect
         to the Project, this Lease shall be subject and subordinate at all ties
         to (a) all ground leases or underlying leases which may now exist or
         hereafter be executed affecting the Project, and (b) the lien of any
         mortgage or deed of trust which may now exist or hereafter be executed
         in any amount for which the Project, ground leases or underlying
         leases, or Landlord's interest or estate in any of said items is
         specified as security. In the event that 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, at the
         option of such successor in interest. Tenant covenants and agrees to
         execute and delivery, upon demand by Landlord and in the form requested
         by Landlord any additional documents evidencing the priority or
         subordination of this Lease with respect to any such ground lease or
         underlying leases or the lien of any such mortgage or Deed of Trust.
         Tenant hereby irrevocably appoints Landlord as attorney-in-fact of
         Tenant to execute, deliver and record any such document in the name and
         on behalf of Tenant.

         Tenant, within ten days from notice from Landlord shall execute and
         deliver to Landlord in recordable form, certificates stating that this
         Lease is not in default, is unmodified and in full force and effect, or
         in full force and effect as modified, and stating the modifications.
         This certificate should also state the amount of current monthly rent
         that dates to which rent has been paid in advance, and the amount of
         any security deposit and prepaid rent. Failure to deliver this
         certificate to Landlord within ten days shall be conclusive upon Tenant
         that this Lease is in full force and effect and has not been modified
         except as may be represented by Landlord.

24.      NOTICE. Any notice, demand, request, consent, approval or communication
         desired by either party or required to be given, shall be in writing
         and served either personally or sent by prepaid certified first class
         mail, addressed as set forth in Section 1. Either party may change its
         address by notification to the other party. Notice shall be deemed to
         be communicated 48 hours from the time of mailing, or from the time of
         service as provided in this Section 24.

25.      WAIVER. No delay or omission in the exercise of any right or remedy by
         Landlord shall impair such right or remedy or be construed as a waiver.
         No act or conduct of Landlord, including without limitation, acceptance
         of the keys to the Premises, shall constitute an acceptance of the
         surrender of the Premises by Tenant before the expiration of the term.
         Only written notice from Landlord to Tenant shall constitute acceptance
         of the surrender



                                       19
   20
         of the Premises and accomplish 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.

26.      SURRENDER OF PROMISES; HOLDING OVER. Upon expiration of the term,
         Tenant shall surrender to Landlord the Premises and all Tenant
         improvements and alterations in good condition, except for ordinary

         possession by Tenant shall be deemed to be a month-to-month tenancy
         terminable on written 30-day notice at any time, by either party. All
         provisions of this Lease, except those pertaining to term and rent,
         shall apply to the month-to-month tenancy. Tenant shall pay monthly
         rent in an amount equal to 125% of Rent for the last full calendar
         month during the regular term plus 100% of said last month's estimate
         of Tenant's share of Expenses pursuant to Section 4.c.3.

27.      LIMITATION OF LIABILITY. In consideration of the benefits accruing
         hereunder, Tenant agrees that, in the event of any actual or alleged
         failure, breach or default of this Lease by Landlord: (a) the sole and
         exclusive remedy shall be against Landlord's interest in the Project,
         (b) no trustee, partner, beneficiary, shareholder, director, officer,
         agent or representative of Landlord shall be sued or named as a party,
         in any suit or action; (c) no service of process shall be made against
         any trustee, partner, beneficiary, shareholder, director, officer,

         of process; (e) no judgment will be taken against any trustee, partner,
         beneficiary, shareholder, director, officer, agent or representative of
         Landlord and any such judgment may be vacated and set aside at any time
         nunc pro tunc; and (f) no writ of execution will ever be levied against
         the assets of any trustee, partner, beneficiary, shareholder, director,
         officer, agent, or representative of Landlord. The obligations of
         Landlord under this Lease do not constitute personal obligations of the


                                       20
   21
         individual trustees, partners, beneficiaries, shareholders, directors,
         officers, agents or representatives of Landlord, and Tenant shall not
         seek recourse against any such parties or any of their personal assets
         for satisfaction of any liability in respect to this Lease. The
         covenants and agreements set forth in this Paragraph 27 are enforceable
         both by Landlord and also by its trustees, partners, beneficiaries,
         shareholders, directors, officers, agents and representatives.

         regulations, and ordinances regarding handicap accessibility. Under no
         circumstances may Tenant make any alterations to the Premises without
         the prior written approval of Landlord.

                  benefit of the parties and their successors, except as

                  representatives, Tenant shall be liable to Landlord for
                  reasonable attorney's fees and court costs incurred by
                  Landlord in the litigation. Should the court render a decision
                  which is thereafter appealed by any party thereto, Tenant
                  shall be liable to Landlord for reasonable attorneys' fees and
                  court costs incurred by Landlord in connection with such
                  appeal.

                  If either party commences any litigation against the other
                  party or files an appeal of a decision arising out of or in
                  connection with the Lease, the prevailing party

                  attorney's fees and costs of suit. If Landlord employs a
                  collection agency to recover delinquent charges, Tenant agrees

                  event Landlord's successor in interest shall be solely
                  responsible for all obligations of Landlord under this Lease.

         g.       INTERPRETATION. This Lease shall be construed and interpreted
                  in accordance with the laws of the state in which the premises
                  are located. This Lease constitutes the entire agreement
                  between the parties with respect to the Premises and the
                  Project, except for such guarantees or modifications as may be
                  executed in writing by the parties from time to time. When
                  required by the context of this Lease, the singular shall
                  include the plural, and the masculine shall include the
                  feminine and/or neuter. "Party" shall mean Landlord or tenant.
                  If more than one person or entity constitutes Landlord or
                  Tenant, the obligations imposed upon that party shall be joint
                  and several. The enforceability, invalidity or illegality of
                  any provision shall not render the other provisions
                  unenforceable, invalid or illegal.

30.      TENANT IMPROVEMENTS. Landlord shall steam clean carpeted areas.
         Additionally, Landlord will touch up the paint in the existing office
         areas in a building standard paint.

31.      OPTION TO RENEW. Tenant shall have one three (3) year renewal option at

         exercise this renewal option not more than 180 days or less than 90
         days prior to the end of the initial lease term. This option shall be
         exercisable only by Tenant, and not by any assignee or sublessee of
         Tenant, either voluntary or otherwise.

32.      EARLY OCCUPANCY. Upon full execution of this Lease by all parries,
         Landlord grants to Tenant the right to enter the Premises prior to the

         and conditions of this Lease. Tenant must provide evidence of insurance
         according to the terms of this Lease prior to any Early Occupancy by
         Tenant.
