The exhibits and addenda listed below (unless lined out) are attached hereto and
incorporated by reference in this Lease:

     3.1  Exhibit A - Floor Plan showing the Premises.

     3.3  Exhibit C - Building Standard Tenant Improvements.

4.   DELIVERY OF POSSESSION.

If for any reason Landlord does not deliver possession of the Premises to Tenant
on the Commencement Date, and such failure is not caused by an act or omission
of Tenant, the Expiration Date shall be extended by the number of days the
Commencement Date has been delayed and the validity of this Lease shall not be
impaired nor shall Landlord be subject to any liability for such failure; but
Rent shall be abated until delivery of possession. Provided, however, if the
Commencement Date has been delayed by an act or omission of Tenant then Rent
shall not be abated until delivery of possession and the Expiration Date shall
not be extended. Delivery of possession shall be deemed to occur on the earlier
of the date Landlord receives a Certificate of Occupancy or upon substantial
completion of the Premises (as certified by Landlord's architect). If Landlord
permits Tenant to enter into possession of the Premises before the Commencement
Date, such possession shall be subject to the provisions of this Lease,
including, without limitation, the payment of Rent (unless otherwise agreed in
writing).

Within ten (10) days of delivery of possession Landlord shall deliver to Tenant
and Tenant shall execute an Acceptance of Premises in which Tenant shall
certify, among other things, that (a) Landlord has satisfactorily completed
Landlord's Work to the Premises pursuant to Exhibit "D", unless written
exception is set forth thereon, and (b) that Tenant accepts the Premises.
Tenant's failure to execute and deliver the Acceptance of Premises shall be
conclusive evidence, as against Tenant, that Landlord has satisfactorily
completed Landlord's Work to the Promises pursuant to Exhibit "D".

In the event Tenant falls to take possession of the Premises following execution
of this Lease, Tenant shall reimburse Landlord promptly upon demand for all
costs incurred by Landlord in connection with entering into this Lease
including, but not limited to, broker fees and commissions, sums paid for the
preparation of a floor and/or space plan for the Premises, costs incurred in
performing Landlord's Work pursuant to Exhibit "D", loss of rental income,
attorneys' fees and costs, and any other damages for breach of this Lease
established by Landlord.

5.   INTENDED USE OF THE PREMISES.

The statement in this Lease of the nature of the business to be conducted by
Tenant in the Premises does not constitute a representation or guaranty by
Landlord as to the present or future suitability of the Premises for the conduct
of such business in the Premises, or that it is lawful or permissible under the
certificate of occupancy issued for the Building, or is otherwise permitted by
law. Tenant's taking possession of the Premises shall be conclusive evidence, as
against Tenant, that, at the time such possession was taken, the Premises were
satisfactory for Tenant's intended use.

6.   RENT.

     6.1.  PAYMENT OF RENT. Tenant shall pay Rent for the Premises. Monthly
Installments of Rent shall be payable in advance on the first day of each
calendar month of the Term. If the Term begins (or ends) on other than the first
(or last) day of a calendar month, Rent for the partial month shall be prorated
based on the number of days in that month. Rent shall be paid to Landlord at the
Rent Payment Address set forth in Section 2.7. or to such other person at such
place as Landlord may from time to time designate in writing, without any prior
demand therefor and without deduction or offset, in lawful money of the United
States or America. Tenant shall pay Landlord the first Monthly Installment of
Base Rent upon execution of this Lease.

     6.3.  ADDITIONAL RENT FOR INCREASES IN TAX COSTS AND OPERATING EXPENSES.
If, in any calendar year during the Term of this Lease, Landlord's Tax Costs and
Operating Expenses (as hereinafter defined) for the Project (hereinafter
sometimes together referred to as Direct Costs) shall be higher than in the Base
Year specified in Section 2.3., Additional Rent for such Direct Costs payable
hereunder shall be increased by an amount equal to Tenant's Proportionate Share
of the difference between Landlord's actual Direct Costs for such calendar year
and the actual Direct Costs of the Base Year. However, if during any calendar
year of the Term the occupancy of the Project is less than ninety-five percent
(95%), then Landlord shall make an appropriate adjustment of the variable
components of Operating Expenses, as reasonably determined by Landlord, to
determine the amount of Operating Expenses that would have been incurred had the
Project been ninety-five percent (95%) occupied during that calendar year. This
estimated amount shall be deemed the amount of Operating Expenses for that
calendar year. For purposes hereof, "variable components" shall include only
those Operating Expenses that are affected by variations in occupancy levels.

          6.3.1. DEFINITIONS. As used in this Section 6.3, the following terms
     shall have the following meanings:

               6.3.1.1. Tax Costs shall mean any and all real estate taxes,
          other similar charges on real property or improvements, assessments,
          water and sewer charges, and all other charges (but in no event

          becoming a lien upon part or all of inheritance, estate, succession,
          transfer, gift, franchise, the Project or the appurtenances thereto,
          or attributable thereto, or on the rents, issues, profits or income
          received or derived therefrom which may be imposed, levied, assessed
          or charged by the United States or the state, county or city in which
          the Project is located, or any other local government authority or
          agency or political subdivision thereof. Tax Costs for each tax year
          shall be apportioned to determine the Tax Costs for the subject
          calendar years.

                       Landlord, at Landlord's reasonable discretion, may
          contest any taxes levied or assessed against the Building or Project
          during the Term. If Landlord contests any taxes levied or assessed
          during the Term, Tenant shall pay Landlord Tenant's Proportionate
          Share of all costs incurred by Landlord in connection with the
          contest.

               6.3.1.2. Operating Expenses shall mean any and all reasonable

          in contracting with a company or companies to provide electricity (or
          any other utility) to the Project, any fees for the installation,
          maintenance, repair or removal of related equipment, and any exit fees

          covering the whole or a substantial part of the Project or the
          Building, or, if not required under any such lease, mortgage or deed

          network (ICN), if any; and the cost of any janitorial, utility or

          6.3.2. DETERMINATION AND PAYMENT OF TAX COSTS AND OPERATING EXPENSES.

               6.3.2.1. On or before the last day of each December during the
          Term of this Lease, Landlord shall furnish to Tenant a written
          statement showing in reasonable detail Landlord's projected Direct
          Costs for the succeeding calendar year. If such statement of projected
          Direct Costs indicates the Direct Costs will be higher than in the
          Base Year, then the Rent due from Tenant hereunder for the next
          succeeding year shall be increased by an amount equal to Tenant's
          Proportionate Share of the difference between the projected Direct
          Costs for the calendar year and the Base Year. If during the course of
          the calendar year Landlord determines that actual Direct Costs will
          vary from its estimate by more than five percent (5%), Landlord may
          deliver to Tenant a written statement showing Landlord's revised
          estimate of Direct Costs. On the next payment date for Monthly
          Installments of Rent following Tenant's receipt of either such
          statement, Tenant shall pay to Landlord an additional amount equal to
          such monthly Rent increase adjustment (as set forth on Landlord's
          statement). Thereafter, the monthly Rent adjustment payments becoming
          due shall be in the amount set forth in such projected Rent adjustment
          statement from Landlord. Neither Landlord's failure to deliver nor
          late delivery of such statement shall constitute a default by Landlord
          or a waiver of Landlord's right to any Rent adjustment provided for
          herein.

               6.3.2.2. On or before the first day of each April during the Term
          of this Lease, Landlord shall furnish to Tenant a written statement of
          reconciliation (the Reconciliation) showing in reasonable detail
          Landlord's actual Direct Costs for the prior year, together with a
          full statement of any adjustments necessary to reconcile any sums paid
          as estimated Rent adjustments during the prior year with those sums
          actually payable for such prior year. In the event such Reconciliation
          shows that additional sums are due from Tenant, Tenant shall pay such
          sums to Landlord within ten (10) days of receipt of such
          Reconciliation. In the event such Reconciliation shows that a credit
          is due Tenant, such credit shall be credited against the sums next
          becoming due from Tenant, unless this Lease has expired or been
          terminated pursuant to the terms hereof (and all sums due Landlord
          have been paid), in which event such sums shall be refunded to Tenant.
          Neither Landlord's failure to deliver nor late delivery of such
          Reconciliation to Tenant by April first shall constitute a default by
          Landlord or operate as a waiver of Landlord's right to collect all
          Rent due hereunder.

               6.3.2.3. So long as Tenant is not in default under the terms of
          the Lease and provided Notice of Tenant's request is given to Landlord
          within thirty (30) days after Tenant's receipt of the Reconciliation,
          Tenant may inspect Landlord's Reconciliation accounting records
          relating to Direct Costs at Landlord's corporate office, during normal
          business hours, for the purpose of verifying the charges contained in
          such statement. The audit must be completed within sixty (60) days of
          Landlord's receipt of Tenant's Notice, unless such period is extended
          by Landlord (in Landlord's reasonable discretion). Before conducting
          any audit however, Tenant must pay in full the amount of Direct Costs
          billed.


                                       5
   8


          Tenant may only review those records that specifically relate to
          Direct Costs. Tenant may not review any other leases or Landlord's tax
          returns or financial statements. In conducting an audit, Tenant must
          utilize an independent certified public accountant experienced in
          auditing records related to property operations. The proposed
          accountant is subject to Landlord's reasonable prior approval. The
          audit shall be conducted in accordance with generally accepted rules
          of auditing practices. Tenant may not conduct an audit more often than
          once each calendar year. Tenant may audit records relating to a
          calendar year only one time. No audit shall cover a period of time
          other than the calendar year from which Landlord's Reconciliation was
          generated. Upon receipt thereof, Tenant shall deliver to Landlord a
          copy of the audit report and all accompanying data. Tenant and
          Tenant's auditor shall keep confidential any agreements involving the
          rights provided in this section and the results of any audit conducted
          hereunder. As a condition precedent to Tenant's right to conduct an
          audit, Tenant's auditor shall sign a confidentiality agreement in a
          form reasonably acceptable to Landlord. However, Tenant shall be
          permitted to furnish information to its attorneys, accountants and
          auditors to the extent necessary to perform their respective services
          for Tenant.

     6.4.  DEFINITION OF RENT. All costs and expenses which Tenant assumes or
agrees or is obligated to pay to Landlord under this Lease shall be deemed
Additional Rent (which, together with the Base Rent is sometimes referred to as
Rent).

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

7.   LATE CHARGES.

If Tenant fails to pay when due any Rent or other amounts or charges which
Tenant is obligated to pay under the terms of this Lease, then Tenant shall pay
Landlord a late charge equal to ten percent (10%) of each such installment if
any such installment is not received by Landlord within five (5) days from the
date it is due. Tenant acknowledges that the late payment of any Rent will cause
Landlord to lose the use of that money and incur costs and expenses not
contemplated under this Lease including, without limitation, administrative
costs and processing and accounting expenses, the exact amount of which is
extremely difficult to ascertain. Landlord and Tenant agree that this late
charge represents a reasonable estimate of such costs and expenses and is fair
compensation to Landlord for the loss suffered from such nonpayment by Tenant.
However, the late charge is not intended to cover Landlord's attorneys' fees and
costs relating to delinquent Rent. Acceptance of any late charge shall not
constitute a waiver of Tenant's default with respect to such nonpayment by
Tenant nor prevent Landlord from exercising any other rights or remedies
available to Landlord under this Lease. Late charges are deemed Additional Rent.

In no event shall this provision for the imposition of a late charge be deemed
to grant to Tenant a grace period or an extension of time within which to pay
any Rent due hereunder or prevent Landlord from exercising any right or remedy
available to Landlord upon Tenant's failure to pay such Rent when due.

8.   SECURITY DEPOSIT.

Upon execution of this Lease, Tenant agrees to deposit with Landlord a Security
Deposit in the amount set forth in Section 2.16. as security for Tenant's
performance of its obligations under this Lease. Landlord and Tenant agree that
the Security Deposit may be commingled with funds of Landlord and Landlord shall
have no obligation or liability for payment of interest on such deposit. Tenant
shall not mortgage, assign, transfer or encumber the Security Deposit without
the prior written consent of Landlord and any attempt by Tenant to do so shall
be void, without force or effect and shall not be binding upon Landlord.
Notwithstanding anything herein to the contrary, in the event that Tenant has
not been in default under the Lease at such time, Landlord will refund one-third
(1/3) of Tenant's Security Deposit ($53,456.00) after the twelfth (12th) full
month of the Lease Term. Further, if Tenant has still not been in default at
such time, then Landlord will refund another one-third (1/3) of Tenant's
Security Deposit ($53,456.00) after the twenty-fourth month of the Lease Term.


                                       6
   9


If Tenant fails to timely pay any Rent or other amount due under this Lease, or
fails to perform any of the terms hereof, Landlord may, at its option and
without prejudice to any other remedy which Landlord may have, appropriate and
apply or use all or any portion of the Security Deposit for Rent payments or any
other amount then due and unpaid, for payment of any amount for which Landlord
has become obligated as a result of Tenant's default or breach, and for any loss
or damage sustained by Landlord as a result of Tenant's default or breach. If
Landlord so uses any of the Security Deposit, Tenant shall, within ten (10) days
after written demand therefor, restore the Security Deposit to the full amount
originally deposited. Tenant's failure to do so shall constitute an act of
default hereunder and Landlord shall have the right to exercise any remedy
provided for in Section 19. hereof.

If Tenant defaults under this Lease more than two (2) times during any calendar
year, irrespective of whether such default is cured, then, without limiting
Landlord's other rights and remedies, Landlord may, in Landlord's sole
discretion, modify the amount of the required Security Deposit. Within ten (10)
days after Notice of such modification, Tenant shall submit to Landlord the
required additional sums. Tenant's failure to do so shall constitute an act of
default, and Landlord shall have the right to exercise any remedy provided for
in Section 19. hereof.

If Tenant complies with all of the terms and conditions of this Lease, and
Tenant is not in default on any of its obligations hereunder, then within thirty
(30) days after Tenant vacates the Premises, Landlord shall return to Tenant
(or, at Landlord's option, to the last subtenant or assignee of Tenant's
interest hereunder) the Security Deposit less any expenditures made by Landlord
to repair damages to the Premises caused by Tenant and to clean the Premises
upon expiration or earlier termination of this Lease.

In the event of bankruptcy or other debtor-creditor proceedings against Tenant,
such Security Deposit shall be deemed to be applied first to the payment of Rent
and other sums due Landlord for all periods prior to the filing of such
proceedings.

9.   TENANT'S USE OF THE PREMISES.

The provisions of this Section are for the benefit of the Landlord and are not
nor shall they be construed to be for the benefit of any tenant of the Building
or Project.

     9.1.  USE. Tenant shall use the Premises solely for the purposes set forth
in Section 2.20. No change in the Use of the Premises shall be permitted, except
as provided in this Section 9.

          9.1.1. If, at any time during the Term hereof, Tenant desires to
     change the Use of the Premises, including any change in Use associated with
     a proposed assignment or sublet of the Premises, Tenant shall provide
     Notice to Landlord of its request for approval of such proposed change in
     Use. Tenant shall promptly supply Landlord with such information concerning
     the proposed change in Use as Landlord may reasonably request. Landlord
     shall have the right to approve such proposed change in Use, which approval
     shall not be unreasonably withheld. Landlord's consent to any change in Use
     shall not be construed as a consent to any subsequent change in Use.

     9.2.  OBSERVANCE OF LAW. Tenant shall not use or occupy the Premises or
permit anything to be done in or about the Premises in violation of any
declarations, covenant, condition or restriction, or law, statute, ordinance or
governmental rules, regulations or requirements now in force or which may
hereafter be enacted or promulgated. Tenant shall, at its sole cost and expense,
upon Notice from Landlord, immediately discontinue any use of the Premises which
is declared by any governmental authority having jurisdiction to be a violation
of law or of the Certificate of Occupancy. Tenant shall promptly comply, at its
sole cost and expense, with all laws, statutes, ordinances and governmental
rules, regulations or requirements now in force or which may hereafter be
imposed which shall by reason of Tenant's Use or occupancy of the Premises,
impose any duty upon Tenant or Landlord with respect to Tenant's Use or
occupation. Further, Tenant shall, at Tenant's sole cost and expense, bring the
Premises into compliance with all such laws, including the Americans With
Disabilities Act of 1990, as amended (ADA), whether or not the necessity for
compliance is triggered by Tenant's Use, and Tenant shall make, at its sole cost
and expense, any changes to the Premises required to accommodate Tenant's
employees with disabilities (any work performed pursuant to this Section shall
be subject to the terms of Section 12. hereof). The judgment of any court of
competent jurisdiction or the admission by Tenant in any action or proceeding
against Tenant, whether Landlord is a party thereto or not, that Tenant has
violated any such law, statute, ordinance, or governmental regulation, rule or
requirement in the use or occupancy of the Premises, Building or Project shall
be conclusive of that fact as between Landlord and Tenant.

     9.3.  INSURANCE. Tenant shall not do or permit to be done anything which
will contravene, invalidate or increase the cost of any insurance policy
covering the Building or Project and/or property located therein, and shall
comply with all rules, orders, regulations, requirements and recommendations of
Landlord's insurance carrier(s) or any board of fire insurance underwriters or
other similar body now or hereafter constituted, relating to or affecting the
condition, use or occupancy of the Premises, excluding structural changes not


                                       7
   10


related to or affected by Tenant's improvements or acts. Tenant shall promptly
upon demand reimburse Landlord for any additional premium charged for violation
of this Section.

     9.4.  NUISANCE AND WASTE. Tenant shall not do or permit anything to be done
in or about the Premises which will in any way obstruct or interfere with the
rights of other tenants or occupants of the Building or Project, or injure or
annoy them, or use or allow the Premises to be used for any improper, unlawful
or objectionable purpose. Tenant shall not cause, maintain or permit any
nuisance in, on or about the Premises. Tenant shall not commit or suffer to be
committed any waste in or upon the Premises.

     9.5.  LOAD AND EQUIPMENT LIMITS. Tenant shall not place a load upon any
floor of the Premises which exceeds the load per square foot which such floor
was designed to carry as determined by Landlord or Landlord's structural
engineer. The cost of any such determination made by Landlord's structural
engineer in connection with Tenant's occupancy shall be paid by Tenant upon
Landlord's demand. Tenant shall not install business machines or mechanical
equipment which will in any manner cause noise objectionable to other tenants or
injure, vibrate or shake the Premises or Building.

     9.6.  HAZARDOUS MATERIAL. Unless Tenant obtains the prior written consent
of Landlord, Tenant shall not create, generate, use, bring, allow, emit,
dispose, or permit on the Premises, Building or Project any toxic or hazardous
gaseous, liquid, or solid material or waste, or any other hazardous material
defined or listed in any applicable federal, state or local law, rule,
regulation or ordinance. If Landlord grants its consent, Tenant shall comply
with all applicable laws with respect to such hazardous material, including all
laws affecting the use, storage and disposal thereof. If the presence of any
hazardous material brought to the Premises, Building or Project by Tenant or
Tenant's employees, agent or contractors results in contamination, Tenant shall
promptly take all actions necessary, at Tenant's sole cost and expense, to
remediate the contamination and restore the Premises, Building or Project to the
condition that existed before introduction of such hazardous material. Tenant
shall first obtain Landlord's approval of the proposed remedial action and shall
keep Landlord informed during the process of remediation,

Tenant shall indemnify, defend and hold Landlord harmless from any claims,
liabilities, costs or expenses incurred or suffered by Landlord arising from
such bringing, allowing, using, permitting, generating, creating, emitting, or
disposing of toxic or hazardous material whether or not consent to same has been
granted by Landlord. Tenant's duty to defend, hold-harmless and indemnify
Landlord hereunder shall survive the expiration or termination of this Lease.
The consent requirement contained herein shall not apply to ordinary office
products that may contain de minimis quantities of hazardous material; however,
Tenant's indemnification obligations are not diminished with respect to the
presence of such products. Tenant acknowledges that Tenant has an affirmative
duty to immediately notify Landlord of any release or suspected release of
hazardous material in the Premises or on or about the Project.

Medical waste and any other waste, the removal of which is regulated, shall be
contracted for and disposed of by Tenant, at Tenant's expense, in accordance
with all applicable laws and regulations. No material shall be placed in Project
trash boxes, receptacles or Common Areas if the material is of such a nature
that it cannot be disposed of in the ordinary and customary manner of removing
and disposing of trash and garbage in the State without being in violation of
any law or ordinance.

10.  SERVICES AND UTILITIES.

Landlord agrees to furnish services and utilities to the Premises during normal
business hours on generally recognized business days subject to the Rules and
Regulations of the Building or Project and provided that Tenant is not in
default hereunder. Services and utilities shall include reasonable quantities of
heating, ventilation and air conditioning (HVAC) as required in Landlord's
reasonable judgment for the comfortable use and occupancy of the Premises;
lighting replacement for building standard lights; window washing and janitor
services in a manner that such services are customarily furnished to comparable
office buildings in the area. Landlord shall supply common area water for
drinking, cleaning and restroom purposes only. Tenant, at Tenant's sole cost and
expense, shall supply all paper and other products used within the Premises.
During normal business hours on generally recognized business days, Landlord
shall also maintain and keep lighted the common stairs, common entries and
restrooms in the Building and shall furnish elevator service and restroom
supplies. If Tenant desires HVAC or other services at any other time, Landlord
shall use reasonable efforts to furnish such service upon reasonable notice from
Tenant, and Tenant shall pay Landlord's charges therefor on demand. Landlord may
provide telecommunications lines and systems as discussed in Section 35. hereof.

Notwithstanding the foregoing, Tenant shall obtain from Landlord at Tenant's
sole cost and expense all electric utilities used at the Premises.

If permitted by law, Landlord shall have the right, in Landlord's reasonable
discretion, at any time and from time to time during the Term, to contract for
the provision of electricity (or any other utility) with, and to switch from,
any company providing such utility. Tenant shall cooperate with Landlord and any
such utility provider at all times, and, as reasonably


                                       8
   11


necessary, Tenant shall allow such parties access to the electric (or other
utility) lines, feeders, risers, wiring and other machinery located within the
Premises.

Landlord shall not be in default hereunder or be liable for any damages directly
or indirectly resulting from, nor shall Rent be abated by reason of (a) the
installation, use or interruption of use of any equipment in connection with the
furnishing of any of the foregoing services, or (b) failure to furnish or delay
in furnishing any such services where such failure or delay is caused by
accident or any condition or event beyond the reasonable control of Landlord, or
by the making of necessary repairs or improvements to the Premises, Building or
Project, or (c) any change, failure, interruption, disruption or defect in the
quantity or character of the electricity (or other utility) supplied to the
Premises or Project, or (d) the limitation, curtailment or rationing of, or
restrictions on, use of water, electricity, gas or any other form of energy
serving the Premises, Building or Project. Landlord shall not be liable under
any circumstances for a loss of or injury to property or business, however
occurring, through, in connection with or incidental to the failure to furnish
any such services.

Tenant shall not, without the prior written consent of Landlord, use any
apparatus or device in the Premises, including, without limitation, electronic
data processing machines, punch card machines, word processing equipment,
personal computers, or machines using in excess of 120 volts, which consumes
more electricity than is usually furnished or supplied for the use of desk top
office equipment and photocopy equipment ordinarily in use in premises
designated as general office space, as determined by Landlord. Tenant shall not
connect any apparatus to electric current except through existing electrical
outlets in the Premises.

Tenant shall not consume electric current in excess of that usually furnished or
supplied for the use of premises as office space (as determined by Landlord),
without first procuring the written consent of Landlord, which Landlord may
refuse. In the event of consent, electrical current shall be separately metered
in Tenant's name and paid for by Tenant. The cost of any such meter and its
installation, maintenance and repair shall be paid by Tenant.

Notwithstanding anything contained herein to the contrary, if Tenant is granted
the right to purchase electricity from a provider other than the company or
companies used by Landlord, Tenant shall indemnify, defend, and hold harmless
Landlord from and against all losses, claims, demands, expenses and judgments
caused by, or directly or indirectly arising from, the acts or omissions of
Tenant's electricity provider (including, but not limited to, expenses and/or
fines incurred by Landlord in the event Tenant's electricity provider fails to
provide sufficient power to the Premises, as well as damages resulting from the
improper or faulty installation or construction of facilities or equipment in or
on the Premises by Tenant or Tenant's electricity provider.

Nothing contained in this Section shall restrict Landlord's right to require at
any time separate metering of utilities furnished to the Premises. If the
separate metering of utilities furnished to the Premises is due to Tenant's
excessive use of electric current, then the cost of any such meter and its
installation, maintenance and repair shall be paid by Tenant. If Landlord
requires separate metering for reasons other than Tenant's excessive consumption
of electric current, then the cost of any such meter and its installation,
maintenance and repair shall be paid by Landlord. In either event, accounts for
all such separately metered utilities shall be in Tenant's name and paid for by
Tenant.

If Tenant uses heat generating machines or equipment in the Premises which
effect the temperature otherwise maintained by the HVAC system, Landlord
reserves the right to install supplementary air conditioning units in the
Premises and the reasonable cost thereof, including the cost of installation,
operation and maintenance thereof, shall be paid by Tenant to Landlord upon
demand therefor.

11.  REPAIRS AND MAINTENANCE.

     11.1. LANDLORD'S OBLIGATIONS. Landlord shall make, at Landlord's sole
expense, all structural repairs except as specified herein and shall maintain in
good order, condition and repair the Building and all other portions of the
Premises not the obligation of Tenant or of any other tenant in the Building. If
applicable, Landlord shall also maintain in good order, condition and repair the
ICN, the cost of which is reimbursable pursuant to Section 6.3.1.2. unless
responsibility therefor is assigned to a particular tenant.

     11.2. TENANT'S OBLIGATIONS.

          11.2.1. Tenant shall, at Tenant's sole expense and except for services

          11.2.2. Tenant shall be responsible for all repairs and alterations in
     and to the Premises, Building and Project and the facilities and systems

          11.2.3. If Tenant fails to maintain the Premises in good order,
     condition and repair, Landlord shall give Notice to Tenant to do such acts
     as are reasonably required to so maintain the Premises. If Tenant fails to
     promptly commence such work and diligently prosecute it to completion, then
     Landlord shall have the right to do such acts and expend such funds at the
     expense of Tenant as are reasonably required to perform such work.

     11.3. COMPLIANCE WITH LAW. Landlord and Tenant shall each do all acts

inconvenience, annoyance, interruption or injury to business arising from
Landlord's making any repairs or changes which Landlord is required or permitted
by this Lease or by any other tenant's lease or required by law to make in or to
any portion of the Project, Building or Premises. Landlord shall nevertheless

Tenant or any person claiming under Tenant.

or built into the Premises and/or Building at the commencement or during the
Term of the Lease (Leasehold Improvements), whether or not by or at the expense
of Tenant, shall be and remain a part of the Premises, shall be the property of
Landlord and shall not be removed by Tenant, except as expressly provided in
Section 13.2., unless Landlord, by Notice to Tenant not later than thirty (30)
days prior to the expiration of the Term, elects to have Tenant remove any
Leasehold Improvements installed by Tenant. In such case, Tenant, at Tenant's
sole cost and expense and prior to the expiration of the Term, shall remove the
Leasehold Improvements and repair any damage caused by such removal.

     13.2 TENANT'S PROPERTY. All signs, notices, displays, movable partitions,

harmless from and against any and all liability and claims of any kind for loss
or damage to any person or property arising out of: (a) Tenant's use and
occupancy of the Premises, or the Building or Project, or any work, activity or
thing done, allowed or suffered by Tenant in, on or about the Premises, the
Building or the Project; (b) any breach or default by Tenant of any of Tenant's
obligations under this Lease; or (c) any negligent or otherwise tortious act or
omission of Tenant, its agents, employees, subtenants, licensees, customers,
guests, invitees or contractors (including agents or contractors who perform
services or work outside of the Premises for Tenant). At Landlord's request,
Tenant shall, at Tenant's expense, and by counsel satisfactory to Landlord,
defend Landlord in any action or proceeding arising from any such claim. Tenant
shall indemnify Landlord against all costs, attorneys' fees, expert witness fees
and any other reasonable expenses or liabilities incurred in such action or
proceeding. As a material part of the consideration for Landlord's execution of
this Lease, Tenant hereby assumes all risk of damage or injury to any person or
property in, on or about the Premises from any cause and Tenant hereby waives
all claims in respect thereof against Landlord, except in connection with damage
or injury resulting from the negligence or willful misconduct of Landlord or its
authorized agents.

     14.2 LANDLORD NOT LIABLE. Landlord shall not be liable for injury or damage
which may be sustained by the person or property of Tenant, its employees,
invitees or customers, or any other person in or about the Premises, caused by
or resulting from fire, steam, electricity, gas, water or rain which may leak or
flow from or into any part of the Premises, or from the breakage, leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning, lighting fixtures or mechanical or electrical systems, whether
such damage or injury results from conditions arising upon the Premises or upon
other portions of the Building or Project or from other sources, unless the
condition was the sole result of Landlord's gross negligence or willful
misconduct. Landlord shall not be liable for any damages arising from any act or
omission of any other tenant of the Building or Project or for


                                       11
   14


the acts of persons in, on or about the Premises, Building or the Project who
are not the authorized agents of Landlord or for losses due to theft, vandalism
or like causes.

Tenant acknowledges that Landlord's election to provide mechanical surveillance
or to post security personnel in the Building or on the Project is solely within
Landlord's discretion. Landlord shall have no liability in connection with the
decision whether or not to provide such services, and, to the extent permitted
by law, Tenant hereby waives all claims based thereon.

15.  TENANT'S INSURANCE.

     15.1. INSURANCE REQUIREMENT. Tenant shall procure and maintain insurance
coverage in accordance with the terms hereof, either as specific policies or
within blanket policies. Coverage shall begin on the date Tenant is given access
to the Premises for any purpose and shall continue until expiration of the Term,
except as otherwise set forth in the Lease. The cost of such insurance shall be
borne by Tenant.

Insurance shall be with insurers licensed to do business in the State, and
acceptable to Landlord. The insurers must have a current A.M. Best's rating of
not less than A:VII, or equivalent (as reasonably determined by Landlord) if the
Best's rating system is discontinued.

Tenant shall furnish Landlord with original certificates and amendatory
endorsements effecting coverage required by this Section 15. before the date
Tenant is first given access to the Premises. All certificates and endorsements
are to be received and approved by Landlord before any work commences. Landlord
reserves the right to inspect and/or copy any insurance policy required to be
maintained by Tenant hereunder, or to require complete, certified copies of all
required insurance policies, including endorsements effecting the coverage
required herein at any time. Tenant shall comply with such requirement within
thirty (30) days of demand therefor by Landlord. Tenant shall furnish Landlord
with renewal certificates and amendments or a "binder" of any such policy at
least twenty (20) days prior to the expiration thereof. Each insurance policy
required herein shall be endorsed to state that coverage shall not be canceled,
except after thirty (30) days' prior written notice to Landlord and Landlord's
lender (if such lender's address is provided).

The Commercial General Liability policy, as hereinafter required, shall contain,
or be endorsed to contain, the following provisions: (a) Landlord and any
parties designated by Landlord shall be covered as additional insureds as their
respective interests may appear; and (b) Tenant's insurance coverage shall be
primary insurance as to any insurance carried by the parties designated as
additional insureds. Any insurance or self-insurance maintained by Landlord
shall be excess of Tenant's insurance and shall not contribute with it.

     15.2. MINIMUM SCOPE OF COVERAGE. Coverage shall be at least as broad as set
forth herein. However, if, because of Tenant's Use or occupancy of the Premises,
Landlord determines, in Landlord's reasonable judgment, that additional
insurance coverage or different types of insurance are necessary, then Tenant
shall obtain such insurance at Tenant's expense in accordance with the terms of
this Section 15.

          15.2.1. Commercial General Liability (ISO occurrence form CG 00 01)
     which shall cover liability arising from Tenant's Use and occupancy of the
     Premises, its operations therefrom, Tenant's independent contractors,
     products-completed operations, personal injury and advertising injury, and
     liability assumed under an insured contract.

          15.2.2. Workers' Compensation insurance as required by law, and
     Employers Liability insurance.

          15.2.3. Commercial Property Insurance (ISO special causes of loss form
     CP 10 30) against all risk of direct physical loss or damage (including
     flood, if applicable), earthquake excepted, for: (a) all leasehold
     improvements (including any alterations, additions or improvements made by
     Tenant pursuant to the provisions of Section 12. hereof) in, on or about
     the Premises; and (b) trade fixtures, merchandise and Tenant's Property
     from time to time in, on or about the Premises. The proceeds of such
     property insurance shall be used for the repair or replacement of the
     property so insured. Upon termination of this Lease following a casualty as
     set forth herein, the proceeds under (a) shall be paid to Landlord, and the
     proceeds under (b) above shall be paid to Tenant.

          15.2.4. Business Auto Liability.

Landlord shall, during the term hereof, maintain in effect similar insurance on
the Building and Common Area.

          15.2.5. Business Interruption and Extra Expense Insurance.


                                       12
   15


     15.3. MINIMUM LIMITS OF INSURANCE. Tenant shall maintain limits not less
than:

          15.3.1. Commercial General Liability: $1,000,000 per occurrence. If
     the insurance contains a general aggregate limit, either the general
     aggregate limit shall apply separately to this location or the general
     aggregate limit shall be at least twice the required occurrence limit.

          15.3.2. Employer's Liability: $1,000,000 per accident for bodily
     injury or disease.

          15.3.3. Commercial Property Insurance: 100% replacement cost with no
     coinsurance penalty provision.

          15.3.4. Business Auto Liability: $1,000,000 per accident.

          15.3.5. Business Interruption and Extra Expense Insurance: In a
     reasonable amount and comparable to amounts carried by comparable tenants
     in comparable projects.

     15.4. DEDUCTIBLE AND SELF-INSURED RETENTION. Any deductible or self-insured
retention in excess of $5,000 per occurrence must be declared to and approved by
Landlord. At the option of Landlord, either the insurer shall reduce or
eliminate such deductible or self-insured retention or Tenant shall provide
separate insurance conforming to this requirement.

     15.5. INCREASES IN INSURANCE POLICY LIMITS. If the coverage limits set
forth in this Section 15. are deemed inadequate by Landlord or Landlord's
lender, then Tenant shall increase the coverage limits to the amounts reasonably
recommended by either Landlord or Landlord's lender. Landlord agrees that any
such required increases in coverage limits shall not occur more frequently than
once every three (3) years.

     15.6. WAIVER OF SUBROGATION. Landlord and Tenant each hereby waive all
rights of recovery against the other and against the officers, employees, agents
and representatives, contractors and invitees of the other, on account of loss
by or damage to the waiving party or its property or the property of others
under its control, to the extent that such loss or damage is insured against
under any insurance policy which may have been in force at the time of such loss
or damage.

     15.7. LANDLORD'S RIGHT TO OBTAIN INSURANCE FOR TENANT. If Tenant fails to
obtain the insurance coverage or fails to provide certificates and endorsements
as required by this Lease, Landlord may, at its option, obtain such insurance
for Tenant. Tenant shall pay, as Additional Rent, the reasonable cost thereof
together with a twenty-five percent (25%) service charge.

16.  DAMAGE OR DESTRUCTION.

     16.1. DAMAGE. If, during the term of this Lease, the Premises or the
portion of the Building necessary for Tenant's occupancy is damaged by fire or
other casualty covered by fire and extended coverage insurance carried by
Landlord, Landlord shall promptly repair the damage provided (a) such repairs
can, in Landlord's opinion, be completed, under applicable laws and regulations,
within one hundred eighty (180) days of the date a permit for such construction
is issued by the governing authority, (b) insurance proceeds are available to
pay eighty percent (80%) or more of the cost of restoration, and (c) Tenant
performs its obligations pursuant to Section 16.4. hereof. In such event, this
Lease shall continue in full force and effect, except that if such damage is not
the result of the negligence or willful misconduct of Tenant, its agents or
employees, Tenant shall be entitled to a proportionate reduction of Rent to the
extent Tenant's use of the Premises is impaired, commencing with the date of
damage and continuing until completion of the repairs required of Landlord under
Section 16.4. If the damage is due to the fault or neglect of Tenant, its agents
or employees and loss of rental income insurance is denied as a result, there
shall be no abatement of Rent.

Notwithstanding anything contained in the Lease to the contrary, in the event of
partial or total damage or destruction of the Premises during the last twelve
(12) months of the Term, either party shall have the option to terminate this
Lease upon thirty (30) days prior Notice to the other party provided such Notice
is served within thirty (30) days after the damage or destruction. For purposes
of this Section 16.1., "partial damage or destruction" shall mean the damage or
destruction of at least thirty-three and one-third percent (33 and 1/3%) of the
Premises, as determined by Landlord in Landlord's reasonable discretion.

     16.2. REPAIR OF PREMISES IN EXCESS OF ONE HUNDRED EIGHTY DAYS. If in
Landlord's opinion, such repairs to the Premises or portion of the Building
necessary for Tenant's occupancy cannot be completed under applicable laws and
regulations within one hundred eighty (180) days of the date a permit for such
construction is issued by the governing authority, Landlord may elect, upon
Notice to Tenant given within thirty (30) days after the date of such fire or
other casualty, to repair such damage and to diligently prosecute repair to
completion, in which event this Lease shall continue in full force and effect,
but the Base Rent shall be partially abated as provided in Section 16.1. If
Landlord does not so elect to make such repairs, this Lease shall terminate as
of the date of such fire or other casualty.


                                       13
   16


     16.3. REPAIR OUTSIDE PREMISES. If any other portion of the Building or
Project is totally destroyed or damaged to the extent that in Landlord's opinion
repair thereof cannot be completed under applicable laws and regulations within
one hundred eighty (180) days of the date a permit for such construction is
issued by the governing authority, Landlord may elect upon Notice to Tenant
given within thirty (30) days after the date of such fire or other casualty, to
repair such damage, in which event this Lease shall continue in full force and
effect, but the Base Rent shall be partially abated as provided in Section 16.1.
If Landlord does not elect to make such repairs, this Lease shall terminate as
of the date of such fire or other casualty.

     16.4. TENANT REPAIR. If the Premises are to be repaired under this Section
16., Landlord shall repair at its cost any injury or damage to the Building and
Building Standard Tenant Improvements, if any. Notwithstanding anything
contained herein to the contrary, Landlord shall not be obligated to perform
work other than Landlord's Work performed previously pursuant to Section 12.1.
hereof. Tenant shall be responsible at its sole cost and expense for the repair,
restoration and replacement of any other Leasehold Improvements and Tenant's
Property (as well as reconstructing and reconnecting Tenant's internal
telecommunication wiring and related equipment). Landlord shall not be liable
for any loss of business, inconvenience or annoyance arising from any repair or
restoration of any portion of the Premises, Building or Project as a result of
any damage from fire or other casualty.

     16.5. ELECTION NOT TO PERFORM LANDLORD'S WORK. Notwithstanding anything to
the contrary contained herein, Landlord shall provide Notice to Tenant of its
intent to repair or replace the Premises (if Landlord elects to perform such
work), and, within ten (10) days of its receipt of such Notice, Tenant shall
provide Notice to Landlord of its intent to reoccupy the Premises. Should Tenant
fail to provide such Notice to Landlord, then such failure shall be deemed an
election by Tenant not to re-occupy the Premises and Landlord may elect not to
perform the repair or replacement of the Premises. Such election shall not
result in a termination of this Lease and all obligations of Tenant hereunder
shall remain in full force and effect, including the obligation to pay Rent.

     16.6. EXPRESS AGREEMENT. This Lease shall be considered an express
agreement governing any case of damage to or destruction of the Premises,
Building or Project by fire or other casualty, and any present or future law
which purports to govern the rights of Landlord and Tenant in such circumstances
in the absence of express agreement shall have no application.

17.  EMINENT DOMAIN.

     17.1. WHOLE TAKING. If the whole of the Building or Premises is lawfully
taken by condemnation or in any other manner for any public or quasi-public
purpose, this Lease shall terminate as of the date of such taking, and Rent
shall be prorated to such date.

     17.2. PARTIAL TAKING. If less than the whole of the Building or Premises is
so taken, this Lease shall be unaffected by such taking, provided that (a)
Tenant shall have the right to terminate this Lease by Notice to Landlord given
within ninety (90) days after the date of such taking if twenty percent (20%) or
more of the Premises is taken and the remaining area of the Premises is not
reasonably sufficient for Tenant to continue operation of its business, and (b)
Landlord shall have the right to terminate this Lease by Notice to Tenant given
within ninety (90) days after the date of such taking. If either Landlord or
Tenant so elects to terminate this Lease, the Lease shall terminate on the
thirtieth (30th) calendar day after either such Notice. Rent shall be prorated
to the date of termination. If this Lease continues in force upon such partial
taking, Base Rent and Tenant's Proportionate Share shall be equitably adjusted
according to the remaining Rentable Area of the Premises and Project.

     17.3. PROCEEDS. In the event of any taking, partial or whole, all of the
proceeds of any award, judgment or settlement payable by the condemning
authority shall be the exclusive property of Landlord, and Tenant hereby assigns
to Landlord all of its right, title and interest in any award, judgment or
settlement from the condemning authority; however, Tenant shall have the right,
to the extent that Landlord's award is not reduced or prejudiced, to claim from
the condemning authority (but not from Landlord) such compensation as may be
recoverable by Tenant in its own right for relocation expenses and damage to
Tenant's Property and damage to Leasehold Improvements installed at the sole
expense of Tenant.

     17.4. LANDLORD'S RESTORATION. In the event of a partial taking of the
Premises which does not result in a termination of this Lease, Landlord shall
restore the remaining portion of the Premises as nearly as practicable to its
condition prior to the condemnation or taking; provided however, Landlord shall
not be obligated to perform work other than Landlord's Work performed previously
pursuant to Section 12.1. hereof, Tenant shall be responsible at its sole cost
and expense for the repair, restoration and replacement of Tenant's Property and
any other Leasehold Improvements.

18.  ASSIGNMENT AND SUBLETTING.

No assignment of this Lease of sublease or all or any part of the Premises shall
be permitted, except as provided in this Section 18.

     18.1. NO ASSIGNMENT OR SUBLETTING. Tenant shall not, without the prior
written consent of Landlord, assign or hypothecate this Lease or any interest
herein or sublet the Premises or any part thereof, or permit the use of the
Premises or any part thereof by any party other than Tenant. Any of the
foregoing acts without such consent shall be voidable and shall, at the option
of Landlord, constitute a default hereunder. This Lease shall not, nor shall any
interest of Tenant herein, be assignable by operation of law without the prior
written consent of Landlord.

          18.1.1. For purposes of this Section 18., the following shall be
     deemed an assignment:

               18.1.1.1. If Tenant is a partnership, any withdrawal or
          substitution (whether voluntary, involuntary, or by operation of law,
          and whether occurring at one time or over a period of time) of any
          partner(s) owning twenty-five (25%) or more (cumulatively) of any
          interest in the capital or profits of the partnership, or the
          dissolution of the partnership;

               18.1.1.2. If Tenant is a corporation, any dissolution, merger,
          consolidation, or other reorganization of Tenant, any sale or transfer
          (or cumulative sales or transfers) of the capital stock of Tenant in
          excess of twenty-five percent (25%), or any sale (or cumulative sales)
          or transfer of fifty-one (51%) or more of the value of the assets of
          Tenant provided, however, the foregoing shall not apply to
          corporations the capital stock of which is publicly traded.

     18.2. LANDLORD'S CONSENT. If, at any time or from time to time during the
Term hereof, Tenant desires to assign this Lease or sublet all or any part of
the Premises, and if Tenant is not then in default under the terms of the Lease,
Tenant shall submit to Landlord a written request for approval setting forth the
terms and provisions of the proposed assignment or sublease, the identity of the
proposed assignee or subtenant, and a copy of the proposed form of assignment or
sublease. Tenant's request for consent shall be submitted to Landlord at least
thirty (30) days prior to the intended date of such transfer. Tenant shall
promptly supply Landlord with such information concerning the business
background and financial condition of such proposed assignee or subtenant as
Landlord may reasonably request. Landlord shall have the right to approve such
proposed assignee or subtenant, which approval shall not be unreasonably
withheld. Landlord's consent to any assignment shall not be construed as a
consent to any subsequent assignment, subletting, transfer of partnership
interest or stock, occupancy or use.

          18.2.1. Landlord's approval shall be conditioned, among other things,
     on Landlord's receiving adequate assurances of future performance under
     this Lease and any sublease or assignment. In determining the adequacy of
     such assurances, Landlord may base its decision on such factors as it deems
     appropriate, including but not limited to:

               18.2.1.1. that the source of rent and other consideration due
          under this Lease, and, in the case of assignment, that the financial
          condition and operating performance and business experience of the
          proposed assignee and its guarantors, if any, shall be equal to or
          greater than the financial condition and operating performance and
          experience of Tenant and its guarantors, if any, as of the time Tenant
          became the lessee under this Lease;

               18.2.1.2. that any assumption or assignment of this Lease will
          not result in increased cost or expense, wear and tear, greater
          traffic or demand for services and utilities provided by Landlord
          pursuant to Section 10. hereof and will not disturb or be detrimental
          to other tenants of Landlord;

               18.2.1.3. whether the proposed assignee's use of the Premises
          will include the use of Hazardous Material, or will in any way
          increase any risk to Landlord relating to Hazardous Material; and

               18.2.1.4. that assumption or assignment of such lease will not
          disrupt any tenant mix or balance in the Project.

          18.2.2. The assignment or sublease shall be on the same terms and
     conditions set forth in the written request for approval given to Landlord,
     or, if different, upon terms and conditions consented to by Landlord;

          18.2.3. No assignment or sublease shall be valid and no assignee or
     sublessee shall take possession of the Premises or any part thereof until
     an executed counterpart of such assignment or sublease has been delivered
     to Landlord;


                                       15
   18


          18.2.4. No assignee or sublessee shall have a further right to assign
     or sublet except on the terms herein contained;

          18.2.5. Any sums or other economic considerations received by Tenant
     as a result of such assignment or subletting, however denominated under the
     assignment or sublease, which exceed, in the aggregate (a) the total sums
     which Tenant is obligated to pay Landlord under this Lease (prorated to
     reflect obligations allocable to any portion of the Premises subleased),
     plus (b) any real estate brokerage commissions or fees payable to third
     parties in connection with such assignment or subletting, shall be shared
     equally by Tenant and Landlord as Additional Rent under this Lease without
     effecting or reducing any other obligations of Tenant hereunder.

If Landlord consents to the proposed transfer, Tenant shall deliver to Landlord
three (3) fully executed original documents (in the form previously approved by
Landlord) and Landlord shall attach its consent thereto. Landlord shall retain
one (1) fully executed original document. No transfer of Tenant's interest in
this Lease shall be deemed effective until the terms and conditions of this
Section 18. have been fulfilled.

     18.3. TENANT REMAINS RESPONSIBLE. No subletting or assignment shall release
Tenant of Tenant's obligations under this Lease or alter the primary liability
of Tenant to pay the Rent and to perform all other obligations to be performed
by Tenant hereunder. The acceptance of Rent by Landlord from any other person
shall not be deemed to be a waiver by Landlord of any provision hereof. Consent
to one assignment or subletting shall not be deemed consent to any subsequent
assignment or subletting. In the event of default by an assignee or subtenant of
Tenant or any successor of Tenant in the performance of any of the terms hereof,
Landlord may proceed directly against Tenant without the necessity of exhausting
remedies against such assignee, subtenant or successor. Landlord may consent to
subsequent assignments or sublets of the Lease or amendments or modifications to
the Lease with assignees of Tenant, without notifying Tenant, or any successor
of Tenant, and without obtaining its or their consent thereto and any such
actions shall not relieve Tenant of liability under this Lease.

     18.4. CONVERSION TO A LIMITED LIABILITY ENTITY. Notwithstanding anything
contained herein to the contrary, if Tenant is a limited or general partnership
(or is comprised of two (2) or more persons, individually or as co-partners, or
entities), the change or conversion of Tenant to (a) a limited liability
company, (b) a limited liability partnership, or (c) any other entity which
possesses the characteristics of limited liability (any such limited liability
entity is collectively referred to herein as a "Successor Entity") shall be
prohibited unless the prior written consent of Landlord is obtained, which
consent may be withheld in Landlord's sole discretion.

          18.4.1. Notwithstanding Section 18.4., Landlord agrees not to
     unreasonably withhold or delay such consent provided that:

               18.4.1.1. The Successor Entity succeeds to all or substantially
          all of Tenant's business and assets;

               18.4.1.2. The Successor Entity shall have a tangible net worth
          (Tangible Net Worth), determined in accordance with generally accepted
          accounting principles, consistently applied, of not less than the
          greater of the Tangible Net Worth of Tenant on (a) the date of
          execution of the Lease, or (b) the day immediately preceding the
          proposed effective date of such conversion; and

               18.4.1.3. Tenant is not in default of any of the terms,
          covenants, or conditions of this Lease on the propose effective date
          of such conversion.

     18.5. PAYMENT OF FEES. If Tenant assigns the Lease or sublets the Premises
or requests the consent of Landlord to any assignment, subletting or conversion
to a limited liability entity, then Tenant shall, upon demand, pay Landlord,
whether or not consent is ultimately given, an administrative fee of Three
Hundred and 00/100 Dollars ($300.00) plus costs and other reasonable expenses
incurred by Landlord in connection with each such act or request.

19.  DEFAULT.

     19.1. TENANT'S DEFAULT. The occurrence of any one or more of the following
events shall constitute a default and breach of this Lease by Tenant.

          19.1.1. If Tenant abandons or vacates the Premises and fails to pay
     rent therefor.

          19.1.2. If Tenant fails to pay any Rent or Additional Rent or any
     other charges required to be paid by Tenant under this Lease and such
     failure continues for three (3) days after receipt of Notice thereof from
     Landlord to Tenant.


                                       16
   19


          19.1.3. If Tenant fails to promptly and fully perform any other
     covenant, condition or agreement contained in this Lease and such failure
     continues for thirty (30) days after Notice thereof from Landlord to
     Tenant, or, if such default cannot reasonably be cured within thirty (30)
     days, if Tenant fails to commence to cure within that thirty (30) day
     period and diligently prosecute to completion.

          19.1.4. Tenant's failure to occupy the Premises within thirty (30)
     days after delivery of possession (as defined in Section 4. hereof).

          19.1.5. Tenant's failure to provide any document, instrument or
     assurance as required by Sections 12., 15., 18. and/or 35. if the failure
     continues for five (5) days after receipt of Notice from Landlord to
     Tenant.

          19.1.6. To the extent provided by law:

               19.1.6.1. If a writ of attachment or execution is levied on this
          Lease or on substantially all of Tenant's Property; or

               19.1.6.2. If Tenant or Tenant's Guarantor makes a general
          assignment for the benefit of creditors; or

               19.1.6.3. If Tenant files a voluntary petition for relief or if a
          petition against Tenant in a proceeding under the federal bankruptcy
          laws or other insolvency laws is filed and not withdrawn or dismissed
          within sixty (60) days thereafter, or if under the provisions of any
          law providing for reorganization or winding up of corporations, any
          court of competent jurisdiction assumes jurisdiction, custody or
          control of Tenant or any substantial part of its property and such
          jurisdiction, custody or control remains in force unrelinquished,
          unstayed or unterminated for a period of sixty (60) days; or

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

               19.1.6.5. If Tenant is a partnership or consists of more than one
          (1) person or entity, if any partner of the partnership or other
          person or entity is involved in any of the acts or events described in
          Sections 19.1.6.1. through 19.1.6.4. above.

     19.2. LANDLORD REMEDIES. In the event of Tenant's default hereunder, then,
in addition to any other rights or remedies Landlord may have under any law or
at equity, Landlord shall have the right to collect interest on all past due
sums (at the maximum rate permitted by law to be charged by an individual), and,
at Landlord's option and without further notice or demand of any kind, to do the
following:

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

          19.2.2. Continue this Lease in effect, reenter and occupy the Premises
     for the account of Tenant, and collect any unpaid Rent or other charges
     which have or thereafter become due and payable; or

          19.2.3. Reenter the Premises under the provisions of Section 19.2.2.,
     and thereafter elect to terminate this Lease and Tenant's right to
     possession of the Premises.

If Landlord reenters the Premises under the provisions of Sections 19.2.2. or
19.2.3. above, Landlord shall not be deemed to have terminated this Lease or the
obligation of Tenant to pay any Rent or other charges thereafter accruing unless
Landlord notifies Tenant in writing of Landlord's election to terminate this
Lease. 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 obligations under the
Lease. In the event of any reentry or retaking of possession by Landlord,
Landlord shall have the right, but not the obligation, to remove all or any part
of Tenant's Property in the Premises and to place such property in storage at a
public warehouse at the expense and risk of Tenant. If Landlord elects to relet
the Premises for the account of Tenant, the rent received by Landlord from such
reletting shall be applied as follows: first, to the payment of any indebtedness
other than Rent due hereunder from Tenant to Landlord; second, to the payment of
any costs of such reletting; third, to the payment of the cost of any
alterations or repairs to the Premises; fourth to the payment of Rent due and
unpaid hereunder; and the balance, if any, shall be held by Landlord and applied
in payment of future Rent as it becomes due. If that portion of Rent received
from the reletting which is applied against the Rent due hereunder is less than
the amount of the Rent due, Tenant shall pay the deficiency to Landlord promptly
upon demand by Landlord. Such deficiency shall be calculated and paid monthly.
Tenant shall also pay to Landlord, as soon as determined, any costs and expenses
incurred by Landlord in connection with such reletting or in making alterations
and repairs to the Premises which are not covered by the rent received from the
reletting.


                                       17
   20


     19.3. DAMAGES RECOVERABLE. Should Landlord elect to terminate this Lease
under the provisions of Section 19.2., Landlord may recover as damages from
Tenant the following:

          19.3.1. PAST RENT. The worth at the time of the award of any unpaid
     Rent that had been earned at the time of termination including the value of
     any Rent that was abated during the Term of the Lease (except Rent that was
     abated as a result of damage or destruction or condemnation); plus

          19.3.2. RENT PRIOR TO AWARD. The worth at the time of the award of the
     amount by which the unpaid Rent that would have been earned between the
     time of the termination and the time of the award exceeds the amount of
     unpaid Rent that Tenant proves could reasonably have been avoided; plus

          19.3.3. RENT AFTER AWARD. The worth at the time of the award of the
     amount by which the unpaid Rent for the balance of the Term after the time
     of award exceeds the amount of the unpaid Rent that Tenant proves could be
     reasonably avoided; plus

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

"The worth at the time of the award" as used in Sections 19.3.1. and 19.3.2.
above, is to be computed by allowing interest at the maximum rate permitted by
law to be charged by an individual. "The worth at the time of the award" as used
in Section 19.3.3. above, is to be computed by discounting the amount at the
discount rate of the Federal Reserve Bank situated nearest to the Premises at
the time of the award plus one percent (1%).

     19.4. LANDLORD'S RIGHT TO CURE TENANT'S DEFAULT. If Tenant defaults in the
performance of any of its obligations under this Lease and Tenant has not timely
cured the default after Notice, Landlord may (but shall not be obligated to),
without waiving such default, perform the same for the account and at the
expense of Tenant. Tenant shall pay Landlord all reasonable costs of such
performance promptly upon written demand therefor, and if paid at a later date
these costs shall bear interest at the maximum rate permitted by law to be
charged by an individual.

     19.5. LANDLORD'S DEFAULT. If Landlord fails to perform any covenant,
condition or agreement contained in this Lease within thirty (30) days after
receipt of Notice from Tenant specifying such default, or, if such default
cannot reasonably be cured within thirty (30) days if Landlord fails to commence
to cure within that thirty (30) day period and diligently prosecute to
completion, then Landlord shall be liable to Tenant for any damages sustained by
Tenant as a result of Landlord's breach; provided, however, it is expressly
understood and agreed that if Tenant obtains a money judgment against Landlord
resulting from any default or other claim arising under this Lease, that
judgment shall be satisfied only out of the rents, issues, profits, and other
income actually received on account of Landlord's right, title and interest in
the Premises, Building or Project, and no other real, personal or mixed property
of Landlord (or of any of the partners which comprise Landlord, if any),
wherever situated, shall be subject to levy to satisfy such judgment.

     19.6. MORTGAGEE PROTECTION. Tenant agrees to send by certified or
registered mail to any first mortgagee or first deed of trust beneficiary of
Landlord whose address has been furnished to Tenant, a copy of any notice of
default served by Tenant on Landlord. If Landlord fails to cure such default
within the time provided for in this Lease, then such mortgagee or beneficiary
shall have such additional time to cure the default as is reasonably necessary
under the circumstances.

     19.7. TENANT'S RIGHT TO CURE LANDLORD'S DEFAULT. If, after Notice to
Landlord of default, Landlord (or any first mortgagee or first deed of trust
beneficiary of Landlord) fails to cure the default as provided herein, then
Tenant shall have the right to cure that default at Landlord's expense, Tenant
shall not have the right to terminate this Lease or to withhold, reduce or
offset any amount against any payments of Rent or any other charges due and
payable under this Lease except as otherwise specifically provided herein.
Tenant expressly waives the benefits of any statute now or hereafter in effect
which would otherwise afford Tenant the right to make repairs at Landlord's
expense or to terminate this Lease because of Landlord's failure to keep the
Premises in good order, condition and repair.

20.  WAIVER.

No delay or omission in the exercise of any right or remedy of Landlord upon any
default by Tenant shall impair such right or remedy or be construed as a waiver
of such default. The receipt and acceptance by Landlord of delinquent Rent shall
not constitute a waiver of any


                                       18
   21


other default; it shall constitute only a waiver of timely payment for the
particular Rent payment involved (excluding the collection of a late charge or
interest).

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

21.  SUBORDINATION AND ATTORNMENT.

This Lease is and shall be subject and subordinate to all ground or underlying
leases (including renewals, extensions, modifications, consolidations and
replacements thereof) which now exist or may hereafter be executed affecting the
Building or the land upon which the Building is situated, or both, and to the
lien of any mortgages or deeds of trust in any amount or amounts whatsoever
(including renewals, extensions, modifications, consolidations and replacements
thereof) now or hereafter placed on or against the Building or on or against
Landlord's interest or estate therein, or on or against any ground or underlying
lease, without the necessity of the execution and delivery of any further
instruments on the part of Tenant to effectuate such subordination.
Nevertheless, Tenant covenants and agrees to execute and deliver upon demand,
without charge therefor, such further instruments evidencing such subordination
of this Lease to such ground or underlying leases, and to the lien of any such
mortgages or deeds of trust as may be required by Landlord.

Notwithstanding anything contained herein to the contrary, if any mortgagee,
trustee or ground lessor shall elect that this Lease is senior to the lien of
its mortgage, deed of trust or ground lease, and shall give written notice
thereof to Tenant, this Lease shall be deemed prior to such mortgage, deed of
trust or ground lease, whether this Lease is dated prior or subsequent to the
date of said mortgage, deed of trust, or ground lease, or the date of the
recording thereof.

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

22.  TENANT ESTOPPEL CERTIFICATES.

     22.1. LANDLORD REQUEST FOR ESTOPPEL CERTIFICATE. Within twenty (20) days
after written request from Landlord, Tenant shall execute and deliver to
Landlord or Landlord's designee, in the form requested by Landlord, a written
statement certifying, among other things, (a) that this Lease is unmodified and
in full force and effect, or that it is in full force and effect as modified and
stating the modifications; (b) the amount of Base Rent and the date to which
Base Rent and Additional Rent have been paid in advance; (c) the amount of any
security deposited with Landlord; and (d) that Landlord is not in default
hereunder or, if Landlord is claimed to be in default, stating the nature of any
claimed default. Any such statement may be conclusively relied upon by a
prospective purchaser, assignee or encumbrancer of the Premises.

     22.2. FAILURE TO EXECUTE. Tenant's failure to execute and deliver such
statement within the time required shall at Landlord's election be a default
under this Lease (without the requirement of giving Notice or Default and an
opportunity to cure) and shall also be conclusive upon Tenant that: (a) this
Lease is in full force and effect and has not been modified except as
represented by Landlord; (b) there are no uncured defaults in Landlord's
performance and that Tenant has no right of offset, counter-claim or deduction
against Rent and (c) not more than one month's Rent has been paid in advance.

23.  NOTICE.

Notice shall be in writing and shall be deemed duly served or given if
personally delivered, sent by certified or registered U.S. Mail, postage prepaid
with a return receipt requested, or sent by overnight courier service, fee
prepaid with a return receipt requested, as follows: (a) if to Landlord, to
Landlord's Address for Notice with a copy to the Building manager, and (b) if to
Tenant, to Tenant's Mailing Address; provided, however, Notices to Tenant shall
be deemed duly served or given if delivered or sent to Tenant at the Premises.
Landlord and Tenant may from time to time by Notice to the other designate
another place for receipt of future Notice. Notwithstanding anything contained
herein to the contrary, when an applicable


                                       19
   22


State statute requires service of Notice in a particular manner, service of that
Notice in accordance with those particular requirements shall replace rather
than supplement any Notice requirement set forth in the Lease.

24.  TRANSFER OF LANDLORD'S INTEREST.

In the event of any sale or transfer by Landlord of the Premises, Building or
Project, and assignment of this Lease by Landlord, Landlord shall be and is
hereby entirely freed and relieved of any and all liability and obligations
contained in or derived from this Lease arising out of any act, occurrence or
omission relating to the Premises, Building, Project or Lease occurring after
the consummation of such sale or transfer, provided the purchaser shall
expressly assume all of the covenants and obligations of Landlord under this
Lease. This Lease shall not be affected by any such sale and Tenant agrees to
attorn to the purchaser or assignee provided all Landlord's obligation hereunder
are assumed by such transferee. If any security deposit or prepaid Rent has been
paid by Tenant, Landlord shall transfer the security deposit or prepaid Rent to
Landlord's successor and upon such transfer, Landlord shall be relieved of any
and all further liability with respect thereto.

25.  SURRENDER OF PREMISES.

     25.1. CLEAN AND SAME CONDITION. Upon the Expiration Date or earlier
termination of this Lease, Tenant shall peaceably surrender the Premises to
Landlord clean and in the same condition as when received, except for (a)
reasonable wear and tear, (b) loss by fire or other casualty, and (c) loss by
condemnation. Tenant shall remove Tenant's Property no later than the Expiration
Date. If Tenant is required by Landlord to remove any additions, alterations, or
improvements under Section 12.3., Tenant shall complete such removal no later
than the Expiration Date. Any damage to the Premises, including any structural
damage, resulting from removal of any addition, alteration, or improvement made
pursuant to Section 12.3. and/or from Tenant's use or from the removal of
Tenant's Property pursuant to Section 13.2. shall be repaired (in accordance
with Landlord's reasonable direction) no later than the Expiration Date by
Tenant at Tenant's sole cost and expense. On the Expiration Date Tenant shall
surrender all keys to the Premises.

     25.2. FAILURE TO DELIVER POSSESSION. If Tenant fails to vacate and deliver
possession of the Premises to Landlord on the expiration or sooner termination
of this Lease as required by Section 25.1., Tenant shall indemnify, defend and
hold Landlord harmless from all claims, liabilities and damages resulting from
Tenant's failure to vacate and deliver possession of the Premises, including,
without limitation, claims made by a succeeding tenant resulting from Tenant's
failure to vacate and deliver possession of the Premises and rental loss which
Landlord suffers.

     25.3. PROPERTY ABANDONED. If Tenant abandons or surrenders the Premises, or
is dispossessed by process of law or otherwise, any of Tenant's Property left on
the Premises shall be deemed to be abandoned, and, at Landlord's option, title
shall pass to Landlord under this Lease as by a bill of sale. If Landlord elects
to remove all or any part of such Tenant's Property, the cost of removal,
including repairing any damage to the Premises or Building caused by such
removal, shall be paid by Tenant.

26.  HOLDING OVER.

Tenant shall not occupy the Premises after the Expiration Date without
Landlord's consent. If after expiration of the Term, Tenant remains in
possession of the Premises with Landlord's permission (express or implied),
Tenant shall become a tenant from month to month only upon all the provisions of
this Lease (except as to the term and Base Rent). Monthly Installments of Base
Rent payable by Tenant during this period shall be increased to one hundred
fifty percent (150%) of the Monthly Installments of Base Rent payable by Tenant
in the final month of the Term. Such monthly rent shall be payable in advance on
or before the first day of each month. The tenancy may be terminated by either
party by delivering a thirty (30) day Notice to the other party. Nothing
contained in this Section 26. shall be construed to limit or constitute a waiver
of any other rights or remedies available to Landlord pursuant to this Lease or
at law.

27.  RULES AND REGULATIONS.

Tenant agrees to comply with (and cause its agents, contractors, employees and
invitees to comply with) the rules and regulations attached hereto as Exhibit
"E" and with such reasonable modifications thereof and additions thereto as
Landlord may from time to time make provided that such rules and regulations do
not materially interfere with the material rights otherwise granted to Tenant
under this Lease. Landlord agrees to enforce the rules and regulations uniformly
against all tenants of the Project. Landlord shall not be liable, however, for
any violation of said rules and regulations by other tenants or occupants of the
Building or Project.


                                       20

28.  CERTAIN RIGHTS RESERVED BY LANDLORD.

Landlord reserves the following rights, exercisable without (a) liability to

address of the Building or Project.

     28.2. To install and maintain all signs on the exterior and interior of the

protection, maintenance or preservation of the Premises or the Building or
Landlord's interest therein, or as may be necessary or desirable for the
operation or improvement of the Building or in order to comply with laws, orders
or requirements of governmental or other authority. Landlord agrees to use its
best efforts (except in an emergency) to minimize interference with Tenant's
business in the Premises in the course of any such entry.

     28.7. To exclusively regulate and control use of the Common Area.

29.  ADVERTISEMENTS AND SIGNS.

the same terms and conditions as provided in the Lease, except that if the new
premises contains more or less square footage, then there shall be a
proportionate adjustment in Rent. Landlord shall pay reasonable expenses
incurred moving Tenant's Property to the new premises. Upon completion of such
relocation, the new premises shall be the Premises for all purposes under the
Lease and the parties shall immediately execute an amendment to this Lease
setting forth the relocation of the Premises and the reduction of Base Rent, if
any.

     35.3. LANDLORD'S CONSENT. Without in any way limiting Landlord's right to

additions or modifications (the Telecommunications Lines serving Tenant in the
Building, Landlord shall consider the following factors in making its
determination:

          35.3.1. If the proposed actions of Tenant and its Telecommunications
     Companies will impose new obligations on Landlord, or expose Landlord to
     liability of any nature or description, or increase Landlord's insurance
     costs for the Building or create liabilities for which Landlord is unable
     to obtain insurance protection, or imperil Landlord's insurance coverage;

          35.3.2. If Tenant's Telecommunications Companies are unwilling to pay
     reasonable monetary compensation for the use and occupation of the Building
     for the Telecommunications Lines;

          35.3.3. If Tenant and its Telecommunications Companies would cause any
     work to be performed that would adversely affect the land and Building or
     any space in the Building in any material manner;

          35.3.4. If Tenant encumbers or mortgages its interest in any
     telecommunications wiring or cabling; or

          35.3.5. If Tenant is in default under this Lease.

     35.4. INDEMNIFICATION. Tenant shall indemnify, defend and hold harmless
Landlord and its employees, agents, officers, and directors from and against any
claims, demands, penalties, fines, liabilities, settlements, damages, costs, or
expenses of any kind or nature, known or unknown, contingent or otherwise,
arising out of or in any way related to the acts and omissions of Tenant,
Tenant's officers, directors, employees, agents, contractors, subcontractors,
subtenants, and invitees with respect to (1) any Telecommunications Lines
serving Tenant in the Building which are on, from, or affecting the Project and
Building; (2) any bodily injury (including wrongful death) or property damage
(real or personal) arising out of or related to any Telecommunications Lines
serving Tenant in the Building which are on, from, or affecting the Building;
(3) any lawsuit brought or threatened, settlement reached, or governmental order
relating to such Telecommunications Lines; (4) any violations of laws, orders,
regulations, requirements, or demands of governmental authorities, or any
reasonable policies or requirements of Landlord, which are based upon or in any
way related to such Telecommunications Lines, including, without limitation,
attorney and consultant fees, court costs, and litigation expenses. This
indemnification and hold harmless agreement will survive this Lease. Under no
circumstances shall Landlord be required to maintain, repair or replace any
Building systems or any portions thereof, when such maintenance, repair or
replacement is caused in whole or in part by the failure of any such system or
any portions thereof, and/or the requirements of any governmental authorities.
Under no circumstances shall Landlord be liable for interruption in
telecommunications services to Tenant or any other entity affected, for
electrical spikes or surges, or for any other cause whatsoever, whether by Act
of God or otherwise, except to the extent the same is caused by the ordinary
negligence of Landlord, Landlord's contractors, subcontractors, or agents or
other tenants, subtenants, or their contractors, subcontractors, or agents.

     35.5. LANDLORD'S OPERATION OF BUILDING TELECOMMUNICATIONS LINES AND
SYSTEMS. Notwithstanding anything contained herein to the contrary, if the point
of demarcation is relocated, Landlord may, but shall not be obligated to,
undertake the operation, repair and maintenance of telecommunications lines and
systems in the Building. If Landlord so elects, Landlord shall give Notice of
its intent to do so, and Landlord shall, based on Landlord's sole business
discretion, make such lines and systems available to tenants of the Building
(including Tenant) in the manner it deems most prudent. Landlord may include in
Operating Expenses all or a portion of the expenses related to the operation,
repair and maintenance of the telecommunications lines and systems.

36.  MISCELLANEOUS.

     36.1. ACCORD AND SATISFACTION; ALLOCATION OF PAYMENTS. No payment by Tenant
or receipt by Landlord of a lesser amount than the Rent provided for in this
Lease shall be deemed to be other than on account of the earliest due Rent, nor
shall any endorsement or statement on any check or letter accompanying any check
or payment as Rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of the Rent or pursue any other remedy provided for in this Lease. In
connection with the foregoing, Landlord shall have the absolute right in its
sole discretion to apply any payment received from Tenant to any account or
other payment of Tenant then not current and due or delinquent.

     there are no uncured defaults in Tenant's performance and that Landlord has
