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 in writing attached as Exhibit C. 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 term and the time when Landlord delivers
      possession to Tenant, 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 and any
            partial month's rent is due and payable upon execution of this
            Lease.

            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
            payments as provided under the terms and conditions of this
            agreement.

      b.    RENT ADJUSTMENT.

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

      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,
            repair or replacement, and insurance of the Project. Accordingly,
            beginning on the first of the calendar year following the date Lease
            Commencement Date, Tenant shall pay to Landlord that portion of
            Tenant's Share (as defined below) of Expenses related to the Project
            which is in excess of the Annual Expense Base shown in Section 1.
            Tenant's prorata share of the operating expenses shall be determined
            on a occupancy level of no less than ninety-five percent (95%).
            Property taxes to be calculated as a fully leased office building
            for one year.

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



                                       2
   3
      (a)   All supplies, materials, labor, equipment, and utilities used in or
            related to the operation and maintenance of the Project;

      (b)   All maintenance, management, common area janitorial, accounting,
            insurance, and service agreement costs related to the Project;

      (c)   All maintenance, replacement and repair costs relating to the areas
            within or around the Project, including, without limitation, 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 replacing roofs, walls, etc.

      (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 Project or any portion thereof, any leasehold
            estate in the Premises or measured by rent from the Premises
            including any 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
            equitable interest of Landlord in the Project or any part thereof;
            (3) upon this 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 Project; or (6) in
            consideration for 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)   The cost of any tax protest incurred in Landlord's attempt to reduce
            real estate taxes.

(2)   ANNUAL ESTIMATE OF EXPENSES - TENANT'S SHARE. When Tenant takes possession
      of the Premises, Tenant's share of Expenses for the remainder of the
      calendar year shall be zero. At the commencement of each calendar year
      thereafter, Landlord shall estimate Tenant's Share of Expenses for the
      coming year by multiplying the estimated annual Project Expenses in excess
      of the Annual Expense Base shown in Section 1 by the Premises area and
      dividing this product by 132,000, the total rentable square footage of the
      Project.

(3)   MONTHLY PAYMENT OF EXPENSES. If Tenant's portion of said estimate of
      Expenses shows an increase for subsequent calendar years over the Annual
      Expense Base, as set forth in Section 1, Tenant shall pay to Landlord, as
      additional rent, such estimated increase in monthly installments of
      one-twelfth (1/12) beginning on January 1 of the forthcoming calendar
      year, and one-twelfth (1/12) on the first day of each succeeding calendar
      month. Landlord shall prepare an accounting of actual Expenses incurred
      during the prior calendar year by March 31st of present 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







                                       3
   4
            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.

      (4)   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 impractical 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 ten (10%) percent 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 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
            charges 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 eighteen (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 $25.00 charge. Should a second payment be returned,
            Tenant agrees to make all future payments by cashier's check, money
            order, or certified check.

5.    FIRST MONTH'S 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.

6.    DEPOSIT. Upon execution of this Lease, Tenant shall deposit a security
      deposit 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 expenses 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. 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 the Lease. In the event Landlord does
      not accept this Lease, Landlord shall return said prepaid deposit.

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 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







                                       4
   5
      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, 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.

            result of the activities and negligence of the Tenant Group during
            Tenant's occupancy of the Property or which exist as a result of the
            breach of any warranty or covenant or the inaccuracy of any
            representation of Tenant contained in this Lease, or by Tenant's
            remediation of the Property or failure to meet its remediation
            obligations contained in this Lease.

      B.    The obligations contained in this Section 8 shall include, but not
            be limited to, the burden and expense of defending all claims, suits
            and administrative proceedings, even if such claims, suits or
            proceedings are groundless, false or fraudulent, and conducting all
            negotiations of any description, and paying and discharging, when
            and as the same become due, any and all judgments, penalties,
            consequential damages or other sums due against such indemnified
            persons. Landlord, at its sole expense, may employ additional
            counsel of its choice to associate with Tenant's counsel.

      C.    Landlord shall have the right, but not the obligation, to join and
            participate in, and control, if it so elects, any legal proceedings
            or actions initiated in connection with Tenant's activities.
            Landlord may also negotiate, defend, approve and appeal any action
            taken or issued by any applicable governmental authority with regard
            to contamination of the Property by a Hazardous Material.

      D.    The obligations of Tenant under this paragraph shall not be affected

            information which Landlord may have or obtain with respect thereto.

8.4.  OBLIGATION TO REMEDIATE.

      In addition to the obligation of Tenant to indemnify Landlord pursuant to
      this Lease, Tenant shall, upon approval and demand of Landlord, at its
      sole cost and expense and using contractors approved by Landlord, promptly
      take all actions to remediate the Property which are required by any
      Governmental Agency, or which are reasonably necessary to mitigate
      Environmental Damages or to allow full economic use of the Property, which
      remediation is necessitated from the presence upon, about or beneath the
      Property, at any time during or upon termination of this Lease, of a
      Hazardous Material or a violation of Environmental Requirements, existing
      as a result of the activities or negligence of the Tenant Group. Such
      actions shall include, but not be limited to, the investigation of the
      environmental condition of the Property, the preparation of any
      feasibility studies, reports or remedial plans, and the performance of any
      cleanup, remediation, containment, operation, maintenance, monitoring or
      restoration work, whether on or off the Property, which shall be performed
      in a manner approved by Landlord. Tenant shall take all actions necessary
      to restore the Property to the condition existing prior to the
      introduction of Hazardous Material upon, about or beneath the Property,
      notwithstanding any lesser standard of remediation allowable under
      applicable law or governmental policies.

8.5.  RIGHT TO INSPECT.

      Landlord shall, have the right in its sole and absolute discretion, but
      not the duty, to enter and conduct an inspection of the Property,
      including invasive tests, at any reasonable time to determine whether
      Tenant is complying with the terms of the Lease, including but not limited
      to the compliance of the Property and the activities thereon with
      Environmental Requirements and the existence of Environmental Damages as a
      result of the condition of the Property or surrounding properties and
      activities thereon. Landlord shall have the right, but not the duty, to
      retain any independent professional consultant (the "Consultant") to enter
      the Property to conduct such an inspection or to review any report
      prepared by or for Tenant concerning such compliance. The cost of the
      Consultant shall be paid by Landlord unless such investigation discloses a
      violation of any Environmental Requirement by the Tenant Group or the
      existence of a Hazardous Material on the Property or any other property
      caused by the activities or negligence of the Tenant Group (other than
      Hazardous Materials used in compliance with all Environmental Requirements
      and previously approved by Landlord), in which case Tenant shall pay the
      cost of the Consultant.

   9
      Tenant hereby grants to Landlord, and the agents, employees, consultants
      and contractors of Landlord the right to enter the Property and to perform
      such tests on the Property as are reasonably necessary to conduct such
      reviews and investigations. Landlord shall use its best efforts to
      minimize interference with the business of Tenant.

8.6.  NOTIFICATION.

      If Tenant shall become aware of or receive notice or other communication
      concerning any actual, alleged, suspected or threatened violation of
      Environmental Requirements, or liability of Tenant for Environmental
      Damages in connection with the Property or past or present activities of
      any person thereon, including, but not limited to, notice or other
      communication concerning any actual or threatened investigation, inquiry,
      lawsuit, claim, citation, directive, summons, proceeding, complaint,
      notice, order, writ, or injunction, relating to same, then Tenant shall
      deliver to Landlord within ten (10) days of the receipt of such notice or
      communication by Tenant, a written description of said violation,
      liability, or actual or threatened event or condition, together with
      copies of any documents evidencing same. Receipt of such notice shall not
      be deemed to create any obligation on the part of Landlord to defend or
      otherwise respond to any such notification.

      If requested by Landlord, Tenant shall disclose to Landlord the names and
      amounts of all Hazardous Materials other than general office supplies
      referred to in this Section 8.2, which were used, generated, treated,
      handled, stored or disposed of on the Property or which Tenant intends to
      use, generate, treat, handle, store or dispose of on the Property. The
      foregoing in no way shall limit the necessity for Tenant obtaining
      Landlord's consent pursuant to Section 8.2 of this Lease.

8.7.  SURRENDER OF PREMISES.

      In the ninety (90) days prior to the expiration or termination of the
      Lease Term, and for up to ninety (90) days after Tenant fully surrenders
      possession of the Property, Landlord may have an environmental assessment
      of the Property performed in accordance with Section 8.5 of this Lease.
      Tenant shall perform, at its sole cost and expense, any clean-up or
      remedial work recommended by the Consultant which is necessary to remove,
      mitigate or remediate any Hazardous Materials and/or contaminations of the
      Property caused by the activities or negligence of the Tenant Group.

8.8.  ASSIGNMENT AND SUBLETTING.

      In the event the Lease provides that Tenant may assign the Lease or sublet
      the Property subject to Landlord's consent and/or certain other
      conditions, and if the proposed assignee's or sublessee's activities in or
      about the Property involve the use, handling, storage or disposal of any
      Hazardous Materials other than those used by Tenant and in quantities and
      processes similar to Tenant's uses in compliance with the Lease, (i) it
      shall be reasonable for Landlord to withhold its consent to such
      assignment or sublease in light of the risk of contamination posed by such
      activities and/or (ii) Landlord may impose an additional condition to such
      assignment or sublease which requires Tenant to reasonably establish that
      such assignee's or sublessee's activities pose no materially greater risk
      of contamination to the Property than do Tenant's permitted activities in
      view of the (a) quantities, toxicity and other properties of the Hazardous
      Materials to be used by such assignee or sublessee, (b) the precautions
      against a release of Hazardous Materials such assignee or sublessee agrees
      to implement, (c) such assignee's or sublessee's financial condition as it
      relates to its ability to fund a major clean-up and (d) such assignee's or
      sublessee's policy and historical record respecting its willingness to
      respond to the clean up of a release of Hazardous Materials. Landlord
      shall also have its approval rights as set forth in Section 19.

8.9.  SURVIVAL OF HAZARDOUS MATERIALS OBLIGATION.

      Tenant's breach of any of its covenants or obligations under this Lease
      shall constitute a material default under the Lease. The obligations of
      Tenant under this Lease shall survive the expiration or earlier
      termination of the Lease without any limitation, and shall constitute
      obligations that are independent and severable from Tenant's covenants and
      obligations to pay rent under the Lease.

      relating to the use of such parking areas, including reasonable
      restrictions on parking by tenants and employees, to designate specific
      spaces for the use of any tenant, to make changes in the parking layout
      from time to time, and to establish reasonable time limits on parking.
      Overnight parking is prohibited and any vehicle violating this or any
      other vehicle regulation adopted by Landlord is subject to removal at the

      the Premises in good condition, including, without limitation, maintaining
      and repairing all walls, lights, storefronts, floors, ceilings, interior

      received all funds necessary for restoration of the Premises from
      insurance proceeds.

14.   ALTERATIONS. Tenant shall not make any alterations to the Premises, or to

      all Tenant's improvements and alterations, including without limitation,
      all items of Tenant responsibility described in Section 13 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 Tenant's
      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 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 within 30 days of execution 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.
      Landlord shall provide proof of insurance upon written request by the
      Tenant.

17.   DESTRUCTION. If during the term of this Lease, 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







                                       11
   12
            threat of condemnation or while legal proceedings for condemnation
            are proceeding; (2) "Date of Taking" means 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 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 consent which
      consent 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 25% 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 25% 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 corporation 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 attorneys 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 creditors, or institutes
      proceedings under the Bankruptcy Act in which Tenant is the bankrupt; or
      if Tenant is a partnership or consists of more than one person or entity,
      if any partner of the partnership or the 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 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.




                                       12
   13
20.   DEFAULT. The occurrence of any of the following shall constitute a default
      by Tenant: (a) a failure to pay rent or other charge when due and Landlord
      has sent to Tenant a three-day written notice of non payment; (b)
      abandonment and vacation of the Premises (failure to occupy and operate
      the Premises for ten consecutive days shall be deemed an abandonment and
      vacation); or (c) failure to perform any other provision of this Lease.

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 later allowed by law): Landlord may
      terminate Tenant's rights 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 light 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, attorney and collection costs, necessary to
      compensate Landlord for all detriment caused by Tenant's default. "The
      Worth," as used for Item 21(1) 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 is 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.

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 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 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 times 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 deliver, upon demand by Landlord and
      in the form requested by Landlord any additional documents evidencing the
      priority or subordination of this Lease with respect to any such ground
      lease or underlying leases or the lien of any such mortgage or








                                       13
   14
      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, the
      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 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 PREMISES; 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 wear and tear and
      alterations Tenant has the right or is obligated to remove under the
      provisions of Section 14 herein. Tenant shall remove all personal property
      from the premises and, if required by Landlord at Landlord's option, shall
      remove including, without limitation, all wallpaper, paneling, and other
      decorative improvements or fixtures and shall perform all restoration made
      necessary by the removal of any alterations or Tenant's personal property
      before the expiration of the term, including for example, restoring all
      wall surfaces to their condition prior to the commencement of this Lease.
      Landlord can elect to retain or dispose of in any manner Tenant's personal
      property not removed from the Premises by Tenant prior to the expiration
      of the term. Tenant waives all claims against Landlord for any damage to
      Tenant resulting from Landlord's retention or disposition of Tenant's
      personal property. Tenant shall be liable to Landlord for Landlord's costs
      for storage, removal or disposal of Tenant's personal property. If Tenant,
      with Landlord's consent, remains in possession of the Premises after
      expiration or termination of the term, or after the date in any notice
      given by Landlord to Tenant terminating this Lease, such 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. If Tenant remains without consent, Landlord
      shall receive rent in an amount equal to 300% of rent for the last full
      month plus 100% at said last month's expenses pursuant to 4.c.3 plus all
      damages and costs associated with the unauthorized occupancy and forcible
      eviction process.

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, if Landlord is a
      partnership:

      a.    The sole and exclusive remedy shall be against the partnership and
            its partnership assets;

      b.    No partner of Landlord shall be sued or named as a party in any suit
            or action;




                                       14
   15
      c.    No service of process shall be made against any partner of Landlord;

      d.    No partner of Landlord shall be required to answer or otherwise
            plead to any service or process;

      e.    No judgment may be taken against any partner of Landlord;

      f.    Any judgment taken against any partner of Landlord shall be vacated
            and set aside at any time without hearing;

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

      h.    These covenants and agreements are enforceable both by Landlord and
            also by any partner of Landlord.

      Tenant agrees that each of the foregoing provisions shall be applicable to
      any covenant or agreement either expressly contained in this Lease or
      imposed by statute or at common law.

28.    MISCELLANEOUS PROVISIONS.

      a.    TIME OF ESSENCE. Time is of the essence of each provision of this
            Lease.

      b.    SUCCESSOR. This Lease shall be binding on and inure to the benefit
            of the parties and their successors, except as provided in Section
            19 herein.

      c.    LANDLORD'S CONSENT. Any consent required by Landlord under this
            Lease must be granted in writing and may be withheld or conditioned
            by Landlord in its sole and absolute discretion.

      d.    COMMISSIONS. Each party represents that it has not had dealings with
            any real estate broker, finder or other person with respect to this
            Lease in any manner, except for the broker identified in Section 1,
            who shall be compensated by Landlord.

      e.    OTHER CHARGES. If Landlord becomes a party to any litigation
            concerning this Lease, the Premises or the Project, by reason of any
            act or omission of Tenant or Tenant's authorized 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
            attorney's 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 shall be entitled to recover from
            the other party reasonable attorney's fees and cost of suit. If
            Landlord employs a collection agency to recover delinquent charges,
            Tenant agrees to pay all collection agency and attorneys' fees
            charged to Landlord in addition to rent, late charges, interest and
            other sums payable under this Lease. Tenant shall pay a charge of
            $75 to Landlord for preparation of a demand for delinquent rent.

      f.    LANDLORD'S SUCCESSORS. If in the event of a sale or conveyance by
            Landlord of the Project, the same shall operate to release Landlord
            from any liability under this Lease, and in such 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

   16
            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.

29.   LEASE CANCELLATION OPTION: Tenant shall be given the one-time right to
      cancel this Lease at the end of the seventy-second (72nd) month, March 31,
      2006, by notifying Landlord, in writing, of its desire to cancel this
      Lease no later than nine (9) months prior to the cancellation date or June
      30, 2005. If Tenant elects to cancel on March 31, 2006, Tenant must

            from the Premises covered by said Lease all trade fixtures,
            furnishings, furniture and equipment located on said Premises and
            owned by Tenant provided, however, all of the foregoing shall be
            removed from the premises by no later than March 31, 2006.

      b.    If Tenant elects to cancel this Lease on March 31, 2006, Tenant

            tenant improvement and lease commission expense.

30.   RIGHT OF FIRST OFFER:

      (1)   OFFER SPACE. During the first six (6) years of this Lease and
            subject to the prior rights of any existing tenants, Tenant shall
            have a one-time right of first offer ("Right of First Offer") to
            lease all, but not part, of the space located in Building #1, as
            shown crosshatched on Exhibit "B" (the "Offer Space") in an "as is"

                              WORK LETTER AGREEMENT

THIS WORK LETTER AGREEMENT is entered into as of the 20th day of October, 1999
by and between PRINCIPAL DEVELOPMENT INVESTORS, L.L.C., an Iowa corporation,
("Landlord') and QUALITY CARE SOLUTIONS, INC., a Nevada corporation, ("Tenant").

RECITALS:

A.    Concurrently with the execution of this Work Letter Agreement, Landlord
      and Tenant have entered into a lease (the "Lease) covering certain
      premises (the Premises') more particularly described in Exhibit A attached
      to the Lease.

B.    In order to induce Tenant to enter into the Lease (which is hereby
      incorporated by reference to the extent applicable) and in consideration
      of the mutual covenants hereinafter contained, Landlord and Tenant hereby
      agree as follows:

1.    COMPLETION SCHEDULE. With ten (10) days after the execution of the Lease
      and this Work Letter Agreement by Landlord and Tenant, Landlord shall
      deliver to Tenant, for Tenant's review and approval, a schedule (the "Work
      Schedule") setting forth a timetable for the planning and completion of
      the installation of the Tenant Improvements (as defined in Paragraph 2
      below) to be constructed in the Premises, and the estimated Commencement
      Date for the Term of the Lease. The Work Schedule shall set forth each of
      the various items of work to be done by or approval to be given by
      Landlord and Tenant in connection with the completion of the Tenant
      Improvements. The Work Schedule shall be submitted to Tenant for its
      approval and, upon approval by both Landlord and Tenant, the approved Work
      Schedule shall become the basis for completing the Tenant Improvements. If
      Tenant shall fail to approve the Work Schedule as it may be modified after
      discussions between Landlord and Tenant, within five (5) business days
      after the date the Work Schedule is first received by Tenant, Landlord
      may, at its option, terminate the lease and all of its obligations
      thereunder, and in the event of such a lease termination Tenant shall be
      responsible for all costs incurred hereunder and under the Lease,
      including but not limited to the cost of Tenant Improvements, lease
      commissions and design fees:

2.    Tenant Improvement Allowance.

      a.    Reference herein to "Tenant Improvements" shall include any or all
            of the following work to be done in the Premises pursuant to the
            Tenant Improvement Plans (defined in Paragraph 3 below):

            (i)   Installation within the Premises of all partitioning, doors,
                  floor coverings, ceiling, painting, millwork and similar
                  items;

            (ii)  All electrical wiring, lighting fixtures, outlets and
                  switches, and other electrical work to be installed within the
                  Premises, and additional panels or transformers to accommodate
                  Tenant's requirements;

            (iii) The furnishing and installation of all duct work, terminal
                  boxes, diffusers and accessories required for the completion
                  of the heating, ventilation and air conditioning systems
                  within the Premises;

            (iv)  All fire and life safety control systems, such as fire walls,
                  sprinklers, halon, fire alarms, including piping, wiring and
                  accessories, installed within the Premises;

            (v)   All plumbing, fixtures, pipes and accessories to be installed
                  within the Premises;

            (vi)  Testing and inspection costs;

            (vii) Contractor's fees, including but not limited to any fees based
                  on general conditions; and





                                       29
   30
            (viii) Construction management by Landlord's representative for the
                  supervision of the tenant improvement installation.

            In no event, however, shall the Tenant Improvements include trade
            fixtures, furniture or equipment of the Tenant.

(b)   Landlord hereby grants to Tenant a "Tenant Improvement Allowance" of
      Twenty-five and no/100 Dollars ($25.00) per square foot. Landlord's
      maximum contribution towards the Tenant Improvements shall be limited to
      said Tenant Improvement Allowance. The Tenant Improvement Allowance shall
      only be used for.

      (i)   Payment of the cost of preparing the space plan and the Tenant
            Improvement Plans, including mechanical, electrical, plumbing and
            structural drawings and of all other aspects necessary to complete
            the Tenant Improvement Plans. The Tenant Improvement Allowance will
            not be used for the payment of extraordinary design work or
            extraordinary or over standard improvements not included within the
            scope of Landlord's Building Standards or for payments to any other
            consultants, designers or architects other than Landlord's architect
            and/or space planner.

      (ii)  The payment of plan check, permit and license fees relating to
            construction of the Tenant Improvements.

      (iii) Construction of the Tenant Improvements; provided, however, that the
            Tenant Improvement Allowance will not be used for Non-Standard
            Improvements, if any, unless Landlord , in its sole discretion,
            agrees in writing to payment of some or all of the Non-Standard
            Improvements out of the Tenant Improvement Allowance.

      (iv)  All other costs expended by Landlord in the construction of the
            Tenant Improvements, including those costs incurred by Landlord for
            construction of elements of the Tenant Improvements in the Premises,
            which construction was performed by Landlord prior to execution of
            this Lease by Landlord and Tenant, which construction is for the
            benefit of tenants and is customarily performed by Landlord prior to
            execution of leases for space in the Project for reasons of
            economics (examples of such construction would include, but not be
            limited to, the extension of mechanical [including heating,
            ventilating and air condition systems] and electrical distribution
            systems outside of the core of the Building, wall construction,
            column enclosures and painting outside of the core of the Building,
            ceiling hanger wires and window treatment).

(c)   The costs of each item referenced in Paragraph 2(b) above shall be charged
      against the Tenant Improvement Allowance. In the event that the cost of
      installing the Tenant Improvements, as established by Landlord's final
      pricing schedule, shall exceed the Tenant Improvement Allowance, or if any
      of the Tenant Improvements are not to be paid out of the Tenant Allowance
      as provided in Paragraph 2(b) above, the excess shall be paid by Tenant to
      Landlord prior to the commencement of construction of the Tenant
      Improvements

(d)   In the event that, after the Tenant Improvement Plans have been prepared
      and a price therefore established by Landlord, Tenant shall require any
      changes or substitutions to the Tenant Improvement Plans, any additional
      costs related hereto shall be paid by Tenant to Landlord prior to the
      commencement of construction of the Tenant Improvements. Landlord shall
      have the right to decline Tenant's request for a change to the Tenant
      Improvement Plans if such changes are inconsistent with the provisions of
      Paragraph 3 and 4 below, or if the change would, in Landlord's opinion,
      unreasonably delay construction of the Tenant Improvements.

(e)   Any unused portion of the Tenant Improvement Allowance upon completion of
      the Tenant Improvements shall not be refunded to Tenant or be available to
      Tenant as a credit against any obligations of Tenant under the Lease.

3.    TENANT IMPROVEMENT PLANS. Immediately after the execution of the Lease and
      this Work Letter Agreement and subject to the time frames required by the
      Work Schedule, Tenant agrees to meet with Landlord's architect and/or
      space planner for the purpose of promptly finalizing a space plan for the
      layout of the Premises. Based upon such space plan, Landlord's architect
      shall prepare final working drawings and specifications for the Tenant
      Improvements. Such final working drawings and specifications are referred
      to herein as the "Tenant Improvement Plans." The Tenant Improvement Plans
      must be consistent with Landlord's standard specifications for tenant
      improvements for the project (the "Building Standard"), as the same may be
      changed from time to time by Landlord.

4.    NON-STANDARD TENANT IMPROVEMENTS. Landlord shall permit Tenant to deviate
      from the Building Standards for the Tenant Improvements (the "Non Standard
      Improvements"), provided that (a) the deviations shall not be of a lesser
      quality than the Building Standards; (b) the total lighting for the
      Premises shall not exceed 1.65 watts per Rentable Square Foot of the
      Premises; (c) the deviations conform to applicable governmental
      regulations and necessary governmental permits and approvals have been
      secured; (d) the deviations do not require building service beyond the
      levels normally provided to other tenants in the Project; and (e) Landlord
      has determined in its sole discretion that the deviations are of a nature
      and quality that are consistent with the overall objectives of Landlord
      for the Project.

      Any Non-Standard improvements made shall remain on and be surrendered with
      the Premises upon expiration of the Term, except that Landlord may, within
      30 days before or 30 days after expiration of the Term, elect to require
      Tenant to remove any Non-Standard Improvements which may have been made to
      the Premises. If Landlord so 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. 60 days after notice of its
      election is given, whichever is later.

5.    FINAL PRICING AND DRAWING SCHEDULE. After the preparation of the
      preliminary tenant improvement plan (attached as Exhibit "I") and after
      Tenant's written approval thereof, in accordance with the Work Schedule,
      Landlord shall cause its architect to prepare and submit to Tenant the
      Tenant Improvement Plans. The Tenant Improvement Plans shall be approved
      by Landlord and Tenant in accordance with the Work Schedule and shall
      thereafter be submitted to the appropriate governmental body by Landlord's
      architect for plan checking and the issuance of a building permit.
      Landlord, with Tenant's cooperation, shall cause to be made to the Tenant
      Improvement Plans any changes necessary to obtain the building permit.
      Concurrent with the plan checking, Landlord shall have prepared a final
      pricing for Tenant's approval, in accordance with the Work Schedule,
      taking into account any modifications which may be required to reflect
      changes in the Tenant Improvement Plans required by the City or County in
      which the Premises are located. After final approval of the Tenant
      Improvement Plans, no further changes may be made thereto without the
      prior written approval from both Landlord and Tenant, and then only after
      agreement by Tenant to pay any excess costs resulting from the design
      and/or construction of such changes. Tenant hereby acknowledges that any
      such changes shall be subject to the terms of Paragraph 7 below.

6.    CONSTRUCTION OF TENANT IMPROVEMENTS. After the Tenant Improvement Plans
      have been prepared and approved, the final pricing has been approved and a
      building permit for the Tenant Improvements has been issued, Landlord
      shall cause its contractor to begin installation of the Tenant
      Improvements in accordance with the Tenant Improvement Plans. Landlord
      shall supervise the completion of such work and shall use reasonable
      commercial efforts to secure substantial completion of the work in
      accordance with the Work Schedule. The cost of such work shall be paid as
      provided in Paragraph 2 above. Landlord shall not be liable for any
      damages, whether direct or consequential, as a result of delays in
      construction beyond Landlord's reasonable control, including, but not
      limited to, war, civil unrest, strike, labor troubles, unusually inclement
      weather, governmental delays, inability to secure governmental approvals
      or permits, governmental restrictions, availability of materials or labor,
      acts of God, or delays by Tenant (or its architect or anyone performing
      services on behalf of Tenant).

7.    COMPLETION AND RENTAL COMMENCEMENT DATE. The commencement of the Term of
      the Lease and Tenant's obligation for the payment of rent under the Lease
      shall commence as of the date referred to in Section 1g of the Lease
      provided, however, that if there shall be a delay in substantial
      completion of the Tenant Improvements as a result of:




                                       31
   32
      (a)   Tenant's failure to approve any items or perform any other
            obligation in accordance with and by the date specified in the Work
            Schedule;

      (b)   Tenant's request for materials, finishes or installations other than
            those readily available;

      (c)   Tenant's changes in the Tenant Improvement Plans after the previous
            approval of the Tenant Improvement Plans by Tenant; or

      (d)   Tenant's request to deviate from the Building Standards for the
            Tenant Improvements;

      then the commencement of the Term of the Lease and the rent commencement
      date shall be accelerated by the number of days of such delay. The Tenant
      Improvements shall be deemed substantially complete notwithstanding the
      fact that minor details of construction, mechanical adjustments or
      decorations which do not materially interfere with Tenant's use and
      enjoyment of the Premises remain to be performed (items normally referred
      to as "Punch List" items).

8.    CERTIFICATE OF OCCUPANCY. Upon completion of the Tenant Improvements and
      the issuance by the City or other relevant government agency of a
      Certificate of Occupancy or other comparable certificate authorizing
      occupancy of the Premises, Tenant will promptly provide Landlord with a
      copy of the Certificate of Occupancy or other such certificate.

            [The remainder of this page is left intentionally blank.]




                                       32
   33
      9.    FORCE MAJEURE. Landlord shall have no liability whatsoever to Tenant
            on account of the inability or delay of Landlord in fulfilling any
            of Landlord's obligations under this Work Letter by reason of
            strike, other labor trouble, governmental controls in connection
            with a national or other public emergency, or shortages of fuel,
            supplies or labor resulting therefrom or any other cause, whether
            similar or dissimilar to the above, beyond Landlord's reasonable
            control. If this Work Letter specifies a time period for performance
            of an obligation of Landlord, that time period shall be extended by
            the period of any delay in Landlord's performance caused by any of
            the events of force majeure described above.

IN WITNESS WHEREOF, this Work Letter Agreement is entered into as of the date
first written above.
