                             OFFICE LEASE AGREEMENT

THIS Lease, dated as of the date specified in the Basic Lease Information which
is attached hereto and incorporated herein for all purposes, is made between
Landlord and Tenant.

                              ARTICLE 1 - PREMISES

Landlord leases to Tenant, and Tenant leases from Landlord for the Term (as
defined below) and subject to the provisions hereof, to each of which Landlord
and Tenant mutually agree, the Premises, which Premises is more particularly
described in the floor plans in EXHIBIT A hereto, together with its
appurtenances, including the right to use, in common with others, the lobbies,
entrances, stairs, elevators, off-street parking and loading areas (for loading
and unloading of materials and supplies), and other public portions of the
Building, which Building is situated on the real property described in Exhibit B
hereto. The Premises shall constitute part of the "Rentable Area," which shall
be determined and defined by Landlord using standards adopted by Building Owners
and Managers Association (BOMA). For purposes of this Lease, the Rentable Area
of the Building and the Rentable Area of the Premises are as provided in the
foregoing Basic Lease Information. The term "Common Areas" shall mean all of the
common facilities now or hereafter under, over, in or adjacent to the Building
designed and intended for use by all Tenants in the Building in common
facilities now or hereafter under, over, in or adjacent to the Building designed
and intended for use by all Tenants in the Building in common with Landlord and
each other.

                                 ARTICLE 2 - TERM

Section 2.01. The term of this Lease (the "Term") shall begin on the
Commencement Date. The Commencement Date shall be the earlier of the date:

      (a)   specified in the Basic Lease Information provided Landlord has
            delivered the Premises with the Building Standard Leasehold
            Improvements as set forth on Exhibit C substantially completed: or

      (b)   of Tenant's occupancy of the Premises for the conduct of Tenant's
            business (i.e. not occupancy for construction purposes) (the
            "Commencement Date").

Unless sooner terminated, the Term shall end at midnight on the Expiration Date
specified in the Basic Lease Information.

Section 2.02 Provided Tenant performs all of Tenant's obligations under this
Lease, including Tenant's covenant for the payment of Rental as defined below,
Tenant shall, during the Term, peaceably and quietly enjoy the Premises without
disturbance from Landlord; subject, however, to the terms of this Lease and any
deeds of trust, restrictive covenants, ground leases, easements, and other
encumbrances to which this Lease now or may become subject and subordinate.

                                       4
<PAGE>

                 ARTICLE 3 - DELIVERY OF THE PREMISES TO TENANT

Before the Commencement Date, Landlord shall substantially complete the floor(s)
or portions thereof on which the Premises are located and shall construct the
Leasehold Improvements, if any, to be constructed or installed by Landlord
pursuant to the provisions of Exhibit C hereto. If for any reason Landlord
cannot deliver the Premises to Tenant by the Commencement Date, this Lease shall
not be void or voidable, nor shall Landlord be liable for any loss or damage
resulting therefrom, except that the Rental shall be waived for the period
between the Commencement Date and the date when Landlord can deliver possession
and Landlord shall extend the Term. Tenant may not enter or occupy the Premises
until it is tendered by Landlord, unless Tenant's entry relates to construction
work in the Premises. The Premises shall be deemed completed and possession
delivered when the Premises is completed to accommodate Tenants use. The terms
of Exhibit C hereto shall govern the construction and installation of all
Leasehold Improvements. The term "Building Standard Leasehold Improvements" as
used herein shall mean those Leasehold Improvements which conform to Building
Standard. The term "Non-Building Standard Leasehold Improvements" as used herein
shall mean all Leasehold Improvements which exceed or deviate from Building
Standard. The terms "Building Standard" and "Non-Building Standard" as used
herein shall have the meanings specified and or indicated in Exhibit C hereto.

          ARTICLE 4 - ACCEPTANCE OF THE PREMISES AND BUILDING BY TENANT

Taking possession of the Premises by Tenant shall be conclusive evidence that
Tenant:

      (a)   accepts the Premises as suitable for the purposes for which they are
            Leased

      (b)   accepts the Building and every part and appurtenance thereof as
            being in a good and satisfactory condition; and

      (c)   waives any defects in the Premises and its appurtenances, except for
            the completion of those items, if any, on any punchlist remaining on
            Exhibit C attached hereto.

Landlord shall not be liable, except for negligence or willful misconduct, to
Tenant or any of its agents, employees, licensees, or invitees for any injury or
damage to person or property due to the condition or design of or any defect in
the Building or its mechanical systems and equipment which may exist or occur,
and Tenant, for itself and its agents, employees, licensees, and invitees,
expressly assumes all risks of injury or damage to person or property, either
proximate or remote, resulting from the condition of the Premises or the
Building.

                               ARTICLE 5 - RENTAL

Section 5.01 Tenant covenants and agrees to pay to Landlord as Rental for the
Premises, in lawful money of the United States, 1/12 of the Annual Base Rental
specified in the Basic Lease Information, payable monthly in advance, without
notice or demand, on the first day of each calendar month. In the event of any
late payments, Tenant agrees to pay a late charge for special handling equal to
5% of the Rental due Rental shall be paid to Landlord, without deduction or
offset, at the address of Landlord specified in the Basic Lease Information or
such other place as Landlord may designate in writing. The first monthly
installment of Rental shall be paid on the Commencement Date, except that if
Commencement Date is a date other than the first day of a calendar month, then
the monthly Rental for the first and last fractional months of the Term shall be
appropriately prorated. The term "Rental" as used herein means the sum of Annual
Base

                                       5
<PAGE>

Rental, Proportionate Share of Operating Expense Excess (as defined in Section
6.01), Parking Rental (as defined in EXHIBIT D hereof) and all other sums,
whether or not expressly denominated as rent, shall constitute Rental for the
purposes of Section 502(b)(7) of the Bankruptcy Code U.S.C. 502(b)(7). A service
charge of 10% of the amount of any checks returned stamped "NSF" will be due and
payable, in addition to the overdue installments to cover Landlord's extra cost
and expense in handling and processing. No payment by Tenant or receipt by
Landlord of a lesser amount than the monthly installment due under this Lease
shall be deemed to be other than on account of the earliest Rental due
hereunder, nor shall any endorsement or statement on any check or payment as
Rental 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 such
Rental or pursue any other remedy provided in this Lease or by law.

Section 5.02 Upon the first anniversary of the Commencement Date of this Lease,
and upon each and every anniversary date thereafter, the then current Annual
Base Rental shall be increased by the Annual Base Rental Rate Increase
(cumulative) as specified in the Basic Lease Information.

                         ARTICLE 6 - OPERATING EXPENSES

Section 6.01. From the Commencement Date until the Fiscal Year End following the
Commencement Date, Tenant shall pay on a monthly basis in advance, without
demand, on the first day of each calendar month, as part of the Annual Base
Rental, Tenant's Proportionate Share of Operating Expenses (as defined in
article 6 and 7) in excess of the Initial Operating Expense Allowance
("Operating Expense Excess"). Such payments shall be calculated and made as
follows:

      (a)   Before the beginning of each Fiscal Year during the Term, Landlord
            shall furnish Tenant with Landlord's reasonable estimate of the
            Operating Expenses and any anticipated Operating Expense Excess for
            such Fiscal Year. On the first day of each month during the Fiscal
            Year, Tenant shall pay Tenant's Proportionate Share of such Fiscal
            Year's estimated Operating Expense Excess in monthly installments of
            1/12th of Tenant's Proportionate Share of the estimated annual
            Operating Expense Excess for such Fiscal Year.

      (b)   By the first day of March of each Fiscal Year during Tenant's
            occupancy (beginning with the Fiscal Year following the Commencement
            Date), or as soon thereafter as possible, Landlord shall furnish to
            Tenant a statement of Landlord's actual Operating Expense Excess for
            the previous Fiscal Year or fraction thereof if the Commencement
            Date occurred after the first day of the previous Fiscal Year. If
            the actual Operating Expense Excess is greater than Landlord's
            estimate, a lump sum payment, considered Rental for all purposes,
            shall be made by Tenant, within 30 days of the delivery of that
            statement, equal to Tenant's Proportionate Share of the actual
            Operating Expense Excess over the Landlord's estimate for the
            previous Fiscal Year. If the actual Operating Expense Excess is less
            than Landlord's estimate, a lump sum payment shall be made by
            Landlord, within 30 days of delivery of that statement, equal to
            Tenant's Proportionate Share of the actual

                                       6
<PAGE>

            Operating Expense Excess under Landlord's estimate. The effect of
            this reconciliation payment or adjustment is that the Tenant shall
            pay during each Fiscal Year during the Term, in addition to the
            Annual Base Rental, Tenant's Proportionate Share of Operating
            Expenses in excess of an amount equal to that Fixed years allowance.
            Said amount is based upon 12 months of building operation with all
            tenants utilizing all services provided by Landlord pursuant to
            Article 7 and Article 8.

      (c)   Intentionally left blank

      (d)   With respect to the last Fiscal Year or partial Fiscal Year, as the
            case may be, during the Term, an adjustment will be made between
            Landlord and Tenant pursuant to Section 6.02, at the appropriate
            time after the Expiration Date. The provisions of the paragraph (d)
            shall survive termination of this Lease with respect to such
            adjustment and any payments owing by either party to the other after
            termination hereof.

Section 6.02. As used herein, "Operating Expense" means all expenses, costs, and
disbursements of every kind which Landlord pays or incurs in connection with the
ownership, operation including, without limitation, the costs of utilities, and
maintenance of the Building, Parking Areas, and exterior areas contained within
the boundaries described in Exhibit B upon which the Building is situated. All
Operating Expenses shall be determined according to generally accepted accrual
accounting principles which shall be consistently applied. Operating Expenses
shall include, but are not limited to, the following:

(a)   Wages, salaries, and fees of all personnel or entities (exclusive of
      Landlord's executive personnel) directly engaged in the operation,
      maintenance, repair, or security of the Building, including taxes,
      insurance, and benefits relating thereto. As to personnel not involved
      exclusively with the administration and operation of the Building, only
      those portions of such expenses reasonably allocable to the Building shall
      be included.

(b)   All supplies and materials used in the operation and maintenance of the
      Building, except for special lighting, relamping and ballasts within any
      Tenant space.

(c)   Expenses of all management, maintenance, janitorial, security, and service
      agreements for the Building and the equipment therein, including, without
      limitation, alarm service, janitorial services, exterior window cleaning,
      elevator maintenance, landscaping, parking facility maintenance, roadway
      and utility maintenance and cleaning, etc.

(d)   Expenses of all insurance relating to the Building for which Landlord is
      responsible hereunder, or which Landlord considers reasonably necessary
      for the operation of the Building, including, without limitation, the cost
      of property, casualty and liability insurance applicable to the Building
      and Landlord's personal property used in connection therewith, and the
      cost of business interruption or rental insurance.

(e)   All taxes, assessments, and other governmental charges, now or hereafter
      applicable to the Building, or any portion thereof, or to Landlord's
      personal property used in connection therewith, and dues (including those
      levied by any Association managing all common areas and easements)
      attributable

                                       7
<PAGE>

      to the Building or its operation, exclusive of any inheritance, gift,
      franchise, income, corporate, or profit taxes which may be assessed
      against Landlord.

(f)   Expenses of repairs and general maintenance (excluding repairs and general
      maintenance paid by proceeds of insurance or by Tenant or other third
      parties, and alterations attributable solely to Tenants of the Building).

(g)   Landlord's Costs related to fees paid to individuals or companies engaged
      in rendering legal, accounting or technical services including efforts to
      reduce Building Ad Valorem Tax expenses.

(h)   All utility costs to Landlord of the Building (exclusive, however, of such
      special utility services as are provided in Section 8.02 hereof),
      including, without limitation, water, power, fuel, heating, lighting, air
      conditioning, and ventilation.

Operating Expenses shall not include specific costs especially billed to and
paid by specific Tenants such as above Building Standard janitor service, above
Building Standard utility service, or other services above Building Standard.

Tenant shall be liable for all taxes levied or assessed against personal
property, furniture, fixtures, or Tenant finish placed by Tenant in the
Premises. If any such taxes for which Tenant is liable are levied or assessed
against Landlord or Landlord's property, and Landlord elects to pay the taxes
based on such increase, Tenant shall pay to Landlord upon demand that part of
such taxes for which Tenant is liable hereunder; provided that Tenant shall have
the right to contest such taxes if Tenant shall have furnished Landlord with
security sufficient in Landlord's reasonable determination.

                        ARTICLE 7 - SERVICES BY LANDLORD

      (c)   any item that consumes more than 0.5 kilowatts at rated capacity or
            requires a voltage other than 120 volt single phase

and such consumption by Tenant shall be deemed excessive usage for which Tenant
shall pay Landlord upon receipt of an invoice for the cost to Landlord of such
usage. Notwithstanding the aforementioned, Tenant acknowledges that the Building
electrical feeders have normal design limitations, such that

      (i)   in no event shall lighting have a design load greater than an
            average of 2.00 watts per Usable square foot, and

      (ii)  collectively, Tenant's equipment and lighting shall not have an
            electrical design load greater than an average of 3.75 watts per
            Usable square foot.

Upon the existence of Tenant's excess electrical requirements, Landlord may, at
its option, upon not less than 30 days prior written notice to Tenant,
discontinue electric services to the Premises until Tenant reduces its power
consumption to the permissible limits. Landlord will not be liable in any way to
Tenant for failure or defect in the supply or character of electric energy or
any other utility service furnished to the Premises because of any requirement,
act, or omission of the public utility servicing the Building. All installations
of electrical fixtures, appliances, and equipment within the Premises shall be
subject to Landlord's prior approval. Landlord's obligation to furnish utility
services shall be subject to the rules and regulations of any municipal or other
governmental authority regulating the business of providing utility services.
When Tenant's use of the Premises consumes power in excess of the Building
Standard lighting and for normal office machines of similar low consumption,
then the usage of such additional consumption shall be determined, at Landlord's
election, either

                                       9
<PAGE>

      (i)   by a survey performed by a reputable consultant selected by Landlord
            (and paid for by Tenant when such additional consumption is proven),
            or

      (ii)  by separate meter in the Premises to be installed, maintained and
            read by Landlord at Tenant's sole expense.

Section 8.03 Failure to furnish, or any stoppage of, the services provided for
in Article 7 above and in this Article 8 resulting from any cause will not make
Landlord liable in any respect for damages to either person, property, or
business, nor be construed as an eviction of Tenant, nor entitle Tenant to any
abatement of Rental, nor relieve Tenant from its obligations under this Lease.
Landlord will, with reasonable diligence, repair any malfunction of the Building
Improvements or facilities, but Tenant will have no claim for rebate, abatement
of Rental, or damages because of any malfunctions or interruptions in service.

                                 ARTICLE 9 - USE

The Premises shall be used for general office purposes, and for no other purpose
and Tenant agrees to use and maintain the Premises in a clean, careful, safe,
lawful, and proper manner.

      ARTICLE 10 - LAWS, ORDINANCES AND REQUIREMENTS OF PUBLIC AUTHORITIES

Tenant shall, at its sole expense,

      (i)   comply with all laws, orders, ordinances, and regulations of
            federal, state, county, and municipal authorities having
            jurisdiction over the Premises,

      (ii)  comply with any direction made pursuant to law of any public officer
            or officers requiring abatement of any nuisance, or imposing any
            obligation, order, or duty upon Landlord or Tenant arising from
            Tenant's use of the Premises or from conditions which have been
            created by or at the insistence of Tenant or required by reason of a
            breach of any of Tenant's obligations hereunder, and

      (iii) indemnify Landlord and hold Landlord harmless from any loss, cost,
            claim, or expense which Landlord may incur or suffer by reason of
            Tenant's failure to comply with its obligations under clauses (i) or
            (ii) above. If Tenant receives written notice of violation of any
            such law, order, ordinance, or regulation, it shall promptly notify
            Landlord thereof.

                ARTICLE 11 - OBSERVANCE OF RULES AND REGULATIONS

Tenant and its employees, agents, visitors, and licensees shall observe
faithfully and comply strictly with all Rules and Regulations attached to this
Lease (EXHIBIT F). Landlord shall at all times have the right to make reasonable
exchanges in and additions to such Rules and Regulation. Any failure by Landlord
to enforce any of the Rules and Regulations now or hereafter in effect, either
against Tenant or any other Tenant in the Building, shall not constitute a
waiver of any such Rules and Regulations. Landlord shall not be liable to Tenant
for the failure or refusal by any other Tenant, guest, invitee, visitor, or
occupant of the Building to comply with any of the Rules and Regulations, but
Landlord shall, after receipt of notice, take reasonable action to assure
compliance.

                            ARTICLE 12 - ALTERATIONS

Section 12.01 Tenant may not, at any time during the Term, without Landlord's
prior written consent (which consent shall not be unreasonably withheld), make
any alterations to the Premises. All alterations shall be made at Tenant's
expense, either by Tenant's contractors which have been approved in writing by
Landlord, or at Landlord's option, by Landlord's contractors on terms reasonably
satisfactory to Tenant, including a fee of 15% of the actual costs to Landlord
for performing such work to cover Landlord's overhead.

Section 12.02 All Leasehold Improvements (whether Building Standard or
Non-Building Standard), alterations, and other physical additions made or
installed by or for Tenant in or to the Premises shall be and remain Landlord's
property, except Tenant's furniture, furnishings, personal property, and
moveable trade fixtures, and shall not be removed without Landlord's written
consent.

                               ARTICLE 13 - LIENS

Tenant shall keep the Premises, the Building, and the property on which the
Building is located, free from any liens arising from any work performed,
materials furnished, or obligations incurred by or at the request of Tenant.
Nothing contained in this Lease shall be construed as Landlord's consent to any
performance of labor or furnishing of any materials for any specific
improvements, alteration, or repair of, or to, the Premises, that would result
in any liens against the Premises or liability of the Landlord. If, based upon
acts of Tenant, any lien is filed against the Premises, the Building, the
Property on which the Building is located, or Tenant's Leasehold interests
therein, Tenant shall discharge same within 10 days after its filing. If Tenant
fails to discharge such lien within such period, then, in addition to any other
right or remedy of Landlord, Landlord may, at its election, discharge the lien
by either paying the amount claimed to be due, obtaining the discharge by
deposit with a court or a title company, or by bonding. Tenant shall pay on
demand any amount paid by Landlord for reasonable attorneys' fees and other
legal expenses of Landlord incurred in defending any such action or in obtaining
the discharge of such lien, together with all necessary disbursements in
connection therewith, to double the amount of the lien claim plus a sufficient
amount to cover any penalties, interest, attorneys' fees, court costs, and other
legal expenses resulting from such contest. This bond shall name Landlord and
such other parties as Landlord may direct as beneficiaries thereunder.

                          ARTICLE 14 - ORDINARY REPAIRS

Tenant shall, at all times during the Term hereof and at Tenant's sole cost and
expense, keep the Premises and every part thereof in good condition and repair,
ordinary wear and tear, fire and other casualty excepted. Subject to Article 20,
section 20.02 herein, Tenant shall, at the end of the term hereof, surrender the
Premises, as repaired, to Landlord in the same condition as when received,
ordinary wear and tear excepted. If Tenant fails to make such repairs promptly,
Landlord may, at its option, make such repairs, and Tenant shall pay Landlord on
demand Landlord's actual costs in making repairs plus a fee of (15%) to cover
Landlord's overhead.

                             ARTICLE 15 - INSURANCE

Section 15.01 Tenant shall, during the Term, at its sole expense, keep in force,
with Tenant, Landlord, and the mortgagees and ground lessors of Landlord named
as additional insured thereunder (except with respect to Worker's Compensation
coverage) all as their respective interests may appear, the following insurance:

      (a)   All Risk Insurance (including fire, extended coverage, vandalism,
            malicious mischief, extended perils, sprinkler leakage and debris
            removal) upon property of every description and kind owned by Tenant
            and located in the Building or for which Tenant is legally liable or
            installed by or on behalf of Tenant including, without limitation,
            fittings, installations, fixtures, removable trade fixtures,
            Non-Building Standard Leasehold Improvements (as defined in EXHIBIT
            C), and alterations, in an amount not less than the full replacement
            cost thereof. If there is a dispute as to the amount which comprises
            full replacement cost, the decision of Landlord or the mortgagees of
            Landlord shall be conclusive and binding.

      (b)   Commercial liability insurance coverage to include death, personal
            injury, bodily injury (not less that $1,000,000 limits), broad form
            property damage (not less than $1,000,000 limits), fire sprinkler
            hazard, operations hazard, owner's protective coverage, contractual
            liability, and products and completed operations liability, with
            combined single liability limits not less than $1,000,000. Such
            coverage shall insure against all liability of Tenant and its
            authorized representatives and visitors arising out of, and in
            connection with, Tenant's use or occupancy of the Premises.

      (c)   Worker's Compensation and Employer's Liability Insurance, with a
            waiver of subrogation endorsement, in form and amount satisfactory
            to Landlord.

      (d)   Any other form or forms of insurance as Tenant or Landlord or the
            mortgagees of Landlord may reasonably require from time to time in
            form, in amounts, and for insurance risks against which a prudent
            Tenant of a comparable size and in a comparable business would
            protect itself.

All policies shall be issued by insurers with a Best's Insurance Reports rating
of A or better and shall be in form satisfactory to Landlord. Tenant agrees that
certificates of insurance on the Landlord's standard form, or certified copies
of each such insurance policy, naming Landlord and its mortgagees as additional
insured, will be delivered to Landlord not later than 5 days prior to the date
that Tenant takes possession of any part of the Premises. All policies shall
contain an undertaking by the insurers to notify Landlord and the mortgagees of
Landlord in writing, by Registered U.S. Mail, not less than 30 days before any
material change, reduction in coverage, cancellation, or other termination
thereof. All insurance shall be primarily as to Landlord and not participating
with any other available insurance. So long as Tenant is not in default,
proceeds of Tenant's insurance shall be available to repair or replace the
insured fixtures and equipment.

Section 15.02 During the Term, Landlord shall insure the Building (but excluding
Non-Building Standard Leasehold Improvements and any other property which Tenant
is obligated to insure under Section 15.01 hereof) against damage by fire and
standard extended coverage perils in an amount equal to the full replacement
cost thereof, and shall provide public liability insurance in such amounts and
with such deductions as Landlord considers appropriate. Landlord may, but shall
not be obligated to, take out and carry any other form or forms of insurance as
it or Landlord's mortgagees may reasonably determine appropriate.
Notwithstanding any contribution by Tenant to the cost of insurance premiums, as
provided herein, Tenant acknowledges that it has no right to receive any
proceeds from any insurance policies carried by Landlord. Landlord will not be
required to carry insurance of any kind on any Non-Building Standard Leasehold
Improvements, on Tenant's furniture or furnishings, or on any of Tenant's
fixtures, equipment,

                                       12
<PAGE>

improvements, or appurtenances under this Lease; and Landlord shall not be
obligated to repair or replace same.

Section 15.03 Tenant shall not keep in the Premises any article which may be
prohibited by any reasonable insurance policy periodically in force covering the
Building. If Tenant's occupancy results in any increase in premiums for the
insurance carried by Landlord, Tenant shall pay any such increase in premiums as
additional Rental within 10 days after being billed therefore. Tenant shall
promptly comply with all reasonable requirements of the insurance authority or
any present or future insurer relating to the Premises and the Building.

Section 15.04 If any of Landlord's insurance policies shall be cancelled or
cancellation shall be threatened or the coverage hereunder reduced or threatened
to be reduced, or if the premiums on any of Landlord's insurance policies are
increased or threatened to be increased, in any way because of Tenant's use of
the Premises and, if Tenant fails to remedy the cause thereof within 48 hours
after notice, Landlord may, at its option, either terminate this Lease or enter
upon the Premises and attempt to remedy such condition, and Tenant shall
promptly pay the cost thereof to Landlord as additional Rental. Landlord shall
not be liable for any damage or injury caused to any property of Tenant or of
others located on the Premises resulting from such entry. If Landlord is unable
to remedy such condition, then Landlord shall have all of the remedies provided
for in this Lease in the event of a default by Tenant.

Section 15.05 All policies covering real or personal property which either party
obtains affecting the Premises shall include a clause or endorsement denying the
insurer any rights of subrogation against the other party to the extent rights
have been waived by the insured before the occurrence of injury or loss.
Landlord and Tenant hereby mutually waive any rights of recovery against the
other for injury or loss due to hazards covered by insurance containing such a
waiver of subrogation clause or endorsement to the extent of the injury or loss
covered thereby.

                   ARTICLE 16 - DAMAGE BY FIRE OR OTHER CAUSE

Section 16.01 Subject to Sections 16.02 and 16.03 hereof, if the Building is
damaged by fire or other casualty so as to affect the Premises, Tenant shall
immediately notify Landlord, who shall (but only if the proceeds from Landlord's
insurance available to Landlord

      (i)   are free from collection by Landlord's mortgagee, ground or primary
            lessor, and

      (ii)  are sufficient)

have the damage repaired with reasonable speed at the expense of Landlord,
subject to delays which may arise by reason of adjustment of loss under
insurance policies and to other delays beyond Landlord's reasonable control.
Provided such damage was not the result of the negligence or willful misconduct
of Tenant, or Tenant's employees or invitees, an abatement in the Rental
hereunder shall be allowed as to that portion of the Premises rendered
untenantable by such damage until such time as Landlord determines that such
damaged portion of the Premises has been made tenantable for Tenant's use.

Section 16.02 If the Premises are damaged or destroyed by any cause whatsoever,
and if, in the Landlord's reasonable opinion the Premises cannot be rebuilt or
made fit for Tenant's purposes within 120 days of the damage or destruction, or
if the proceeds from insurance remaining after payment of any such proceeds to
Landlord's mortgagee, ground, or primary lessor, are insufficient to repair or
restore the damage by destruction, Landlord may, at its option, terminate this
Lease by giving the Tenant, within 60 days after such damage or destruction,
notice of termination, and thereupon Rental and any other payments for which

                                       13
<PAGE>

Tenant is liable under this Lease shall be apportioned and paid to the date of
such damage, and Tenant shall immediately vacate the Premises, provided,
however, that those provisions of this Lease which are designated to cover
matters of termination and the period thereafter shall survive the termination
hereof.

Section 16.03 If either

      (a)   the Building is damaged or destroyed to the extent that, in
            Landlord's reasonable opinion it would not be economically feasible
            to repair or restore such damage or destruction, or

      (b)   in Landlord's reasonable judgment, the damage or destruction to the
            Building cannot be repaired or restored within 60 days after such
            damage or destruction,

Landlord may, at its option, terminate this Lease by giving Tenant, within 60
days after such damage, notice of such termination requiring Tenant to vacate
the Premises 60 days after delivery of the notice of termination, and thereupon
Rental and any other payments shall be apportioned and paid to the date on which
possession is relinquished and Tenant shall immediately vacate the Premises
according to such notice of termination, provided, however, that those
provisions of this Lease which are designed to cover matters of termination and
the period thereafter shall survive the termination hereof.

Section 16.04 No damages shall be payable by Landlord for inconvenience, loss of
business, or annoyance arising from any repair or restoration of any portion of
the Premises, or the Building. Landlord shall use its best efforts to have such
repairs made promptly so as not to unnecessarily interfere with Tenant's
occupancy.

Section 16.05 The provisions of this Article shall be considered an express
agreement governing any case of damage or destruction of the Building, the
Building Standard Leasehold Improvements, the Non-Building Standard Leasehold
Improvements, the alterations, or the Premises by fire or other casualty.

                            ARTICLE 17 - CONDEMNATION

If the Premises shall be taken or condemned, in whole or in part, for any public
purpose to such an extent as to render said Premises untenantable, this Lease
shall, at the option of Landlord or Tenant, forthwith terminate. All proceeds
from any taking or condemnation shall belong to and be paid to Landlord, except
to the extent of any proceeds awarded to Tenant on account of moving and
relocation expenses and depreciation to and removal of Tenant's physical
property.

                     ARTICLE 18 - ASSIGNMENT AND SUBLETTING

Section 18.01 If Tenant should desire to assign this Lease or sublet the
Premises (or any part thereof), Tenant shall give Landlord written notice at
least 60 days in advance thereof. Landlord shall then have a period of 30 days
following receipt of such notice within which to notify Tenant in writing that
Landlord elects either

      (a)   to terminate this Lease as to the space so affected by Tenant in its
            notice, in which event Tenant, subject to the provisions of this
            Lease which expressly survive the termination hereof, shall be
            relieved of all further obligations hereunder as to such space;

                                       14
<PAGE>

      (b)   to permit Tenant to assign or sublet such space, subject, however,
            to the subsequent written approval of the proposed assignee or
            subtenant by Landlord, and provided that if the Rental rate agreed
            upon between Tenant and its proposed subtenant is greater than the
            Rental rate that Tenant must pay Landlord hereunder, then 100% of
            such excess Rental shall be considered additional Rental owed by
            Tenant to Landlord, and shall be paid by Tenant to Landlord in the
            same manner that Tenant pays Annual Base Rental; or

      (c)   to refuse to consent to Tenant's assignment or subleasing of such
            space and to continue this Lease in full force and effect as to the
            entire Premises, in which case, any judgment against Landlord for
            unreasonable denial shall be limited to specific performance of
            approval of said assignment or sublease.

No assignment or subletting by Tenant shall relieve Tenant of Tenant's
obligations under this Lease. Any attempted assignment or sublease by Tenant in
violation of the terms and provisions of this Section 18.01 shall be void. In no
event shall Tenant solicit assignees or sub lessees in other Buildings owned by
Landlord, or at less than a fair market rate.

Section 18.02 Landlord may sell, transfer, assign, and convey all or any part of
the Building and any and all of its rights under this Lease, provided Landlord's
successor in interest assumes Landlord's obligations hereunder, and in the event
Landlord assigns its rights under this Lease, Landlord shall be released from
any further obligations hereunder, and Tenant agrees to look solely to
Landlord's successor in interest for performance of such obligations.

                          ARTICLE 19 - INDEMNIFICATION

Tenant waives all claims against Landlord for damage to any property or injury
to, or death of, any person in, upon, or about the Building, the Premises or
Parking Facilities arising at any time and from any and all causes whatsoever
other than solely by reason of the negligence or willful misconduct of Landlord,
its agents, employees, representatives, or contractors, and Tenant agrees that
it will defend, indemnify, save, and hold harmless, Landlord from and against
all claims, demands, actions, damages, loss, cost, liabilities, expenses, and
judgments suffered by, recovered from, or asserted against Landlord on account
of any damage to any property or injury to, or death of, any person arising from
the use of the Building, the Premises, or the Parking Facilities by Tenant or
its employees or invitees, except such as is caused solely by the negligence or
willful misconduct of Landlord, its agents, employees, representatives, or
contractors. Tenant's foregoing indemnity obligation shall include reasonable
attorneys' fees and all other reasonable costs and expenses incurred by
Landlord. The provisions of this Article 19 shall survive the termination of
this Lease with respect to any damage, injury, or death occurring before such
termination. If Landlord is made a party to any litigation commenced by or
against Tenant or relating to this Lease or to the Premises, and provided that
in any such litigation, Landlord is not finally adjudicated to be at fault, then
Tenant shall pay all costs and expenses, including attorneys' fees and court
costs, incurred by or imposed upon Landlord because of any such litigation, and
the amount of all such costs and expenses, including attorneys' fees and court
costs, shall be a demand obligation owing by Tenant to Landlord, and shall be
considered as additional Rental.

                     ARTICLE 20 - SURRENDER OF THE PREMISES

Section 20.01 Upon the expiration or other termination of this Lease for any
cause whatsoever, Tenant shall peacefully vacate the Premises in as good order
and condition as the same were at the beginning of the Term or may thereafter
have been improved by Landlord or Tenant, subject only to reasonable use and
wear thereof, and repairs which are Landlord's obligation hereunder.

                                       15
<PAGE>

Section 20.02 Landlord may require Tenant to remove any Non-Building Standard
Leasehold Improvements, alterations, and physical additions installed in the
Premises upon termination of this Lease. In the event Landlord so elects, and
Tenant fails to remove the aforementioned items, Landlord may remove and store
same at Tenant's cost, and Tenant shall pay Landlord on demand, the cost of
restoring the Premises to Building Standard, ordinary wear and tear excepted.
Tenant agrees to remove, at Tenant's expense, all of its furniture, furnishings,
personal property, and moveable trade fixtures by the Expiration Date, and shall
promptly reimburse Landlord for the cost of repairing all damage done to the
Premises or the Building by such removal.

Section 20.03 Should Tenant continue to hold the Premises after the termination
of this Lease, whether the termination occurs by lapse of time or otherwise,
such holding over shall, unless otherwise agreed to by Landlord in writing,
constitute and be construed as a tenancy at will at a monthly Rental equal to
2.5 times the monthly Rental Rate for the Premises as of the date of
termination, and subject to all of the other terms set forth herein except any
right to renew or expand this Lease. Tenant shall be liable to Landlord for all
damage which Landlord suffers because of any holding over by Tenant, and Tenant
shall indemnify Landlord against all claims made by any other Tenant or
prospective Tenant against Landlord resulting from delay by Landlord in
delivering possession of the Premises to such other Tenant or prospective
Tenant.

                       ARTICLE 21 - ESTOPPEL CERTIFICATES

Tenant agrees to furnish, when requested by Landlord or the holder of any deed
of trust covering the Building, the Land, or any interest of Landlord therein, a
certificate signed by Tenant certifying to such parties as Landlord may
designate to the extent true matters with respect to the terms and status of
this Lease and the Premises, stating that Tenant, as of the date of such
certificate, has no charge, lien, or claim of offset under this Lease or
otherwise against Rentals or other charges due or to become due hereunder; and
such other matters as may be requested by Landlord or the holder of any such
deed of trust. To the extent any such statements requested are not true, Tenant
shall explain such facts in writing. Landlord agrees periodically to furnish,
when reasonably requested in writing by Tenant, certificates signed by Landlord
containing substantially the same information as described above.

                           ARTICLE 22 - SUBORDINATION

Section 22.01 This Lease is subject and subordinate to any deeds of trust,
mortgages, or other security instruments, and any other supplements or
amendments thereto, which presently or may in the future cover the Building and
the Land or any interest of Landlord therein, and to any increases, renewals,
modifications, consolidations, replacements, and extensions of any of such deeds
of trust, mortgages, or security instruments. Landlord agrees to use his best
efforts to obtain for Tenant a "non-disturbance" agreement from the holder or
beneficiary of any deeds of trust, mortgages or other security instruments that
in the future may cover the Building and the Land or any interest of Landlord
therein. This provision is declared by Landlord and Tenant to be self-operative
and no further instrument shall be required to effect such subordination of this
Lease. Tenant shall, however, upon demand, execute, acknowledge, and deliver to
Landlord any further instruments and certificates evidencing such subordination
as Landlord may require. This Lease is further subject and subordinate to

      (a)   all ground or primary Leases in existence at the date hereof and to
            any supplements, modifications, and extensions thereof heretofore or
            hereafter made, and

      (b)   utility easements and agreements, covenants, restrictions, and other
            encumbrances which do not materially adversely effect Tenant's
            intended use of the Premises, both existing and future.

                                       16
<PAGE>

Section 22.02 Notwithstanding the generality of the foregoing provisions of
Section 22.01 hereof, any such mortgagee or ground or primary lessor shall have
the right at any time to subordinate any such ground or primary Leases, deeds of
trust, mortgages, or other security instruments to this Lease on such terms and
subject to such conditions as such mortgagee or ground or primary lessor may
consider appropriate in its discretion. At any time, before or after the
institution of any proceedings for the foreclosure of any such deeds of trust,
mortgages, or other security instruments or termination of any ground or primary
Lease, or sale of the Building under any such deeds of trust, mortgages, or
other security instruments or termination of any ground or primary Lease, Tenant
shall attorn to such ground or primary lessor or such purchaser upon any such
sale or the grantee under any deed in lieu of such foreclosure and shall
recognize such ground or primary lessor or such purchaser or grantee as Landlord
under this Lease. The agreement of Tenant to attorn contained in the immediately
preceding sentence shall survive any such termination of any ground or primary
Lease, foreclosure sale, trustee's sale, or conveyance in lieu thereof. Tenant
shall upon demanded at any time, before or after any such termination, execute,
acknowledge, and deliver to Landlord's mortgagee or ground or primary lessor any
written instruments and certificates evidencing such attornment as Landlord's
mortgagee or ground or primary lessor may reasonably require.

                              ARTICLE 23 - PARKING

Landlord will permit Tenant to use the areas designated by Landlord ("Parking
Area") for parking of vehicles in common with other Tenants in the office park
during the Term as more fully provided for in EXHIBIT D hereto.

                        ARTICLE 24 - DEFAULT AND REMEDIES

Section 24.01 The occurrence of any one or more of the following events shall,
at Landlord's option, constitute an event of default of this Lease:

      (a)   if Tenant shall fail to pay any Rental or other sums payable by
            Tenant hereunder within 10 days of written notice thereof from

            Tenant's obligations under this Lease under any section or chapter

            similar law or statute of the United States or any state thereof;

do one or more of the following without any additional notice or demand:

      (a)   Terminate this Lease, in which event Tenant shall immediately
            surrender the Premises to Landlord. If Tenant fails to do so,
            Landlord may, without notice and without prejudice to any other
            remedy Landlord may have, enter upon and take possession of the
            Premises and expel or remove Tenant and its effects without being
            liable to prosecution or any claim for damages therefor; and Tenant
            shall be liable to Landlord for all loss and damage which Landlord
            may suffer by reason of such termination, whether through inability
            to relet the Premises or otherwise, including any loss of Rental for
            the remainder of the Term. Any such loss of Rental shall be offset
            by any Rental received by Landlord as a result of reletting the
            Premises during the remainder of the Term.

      (b)   Terminate this Lease, in which event Tenant's event of default shall
            be considered a total breach of Tenant's obligations under this
            Lease and Tenant immediately shall become liable for such damages
            for such breach amount, equal to the total of:

            (1)   the costs of recovering the Premises;

            (2)   the unpaid Rental earned as of the date of termination, due
                  for the remaining term as of the date of termination, plus
                  interest thereon at a rate per annum from the due date equal
                  to 5% percent over the Prime Rate; provided, however, that
                  such interest shall never exceed the Highest Lawful Rate;

            (3)   the total Rental and other benefits which Landlord would have
                  received under the Lease for the remainder of the Term, at the
                  rates then in effect, together with all other expenses
                  incurred by Landlord in connection with Tenant's default

            (3)   the amount of the excess of

                  (i) the total Rental and other benefits which Landlord would
                  have received under the Lease for the remainder of the Term,
                  at the rates then in effect, together with all other expenses
                  occurred by Landlord in connection with Tenant's default, over

                  (ii) the Fair Market Rate of the balance of the Term as of the
                  time of such breach,

                  which excess shall be discounted at the rate of 8% per annum
                  to the then present value: and

            (4)   all other sums of money and damages owing by Tenant and
                  Landlord.

      (c)   Enter upon and take possession of the Premises as Tenant's agent
            without terminating this Lease and without being liable to
            prosecution or any claim for damages therefor, and Landlord may
            relet the Premises as Tenant's agent and receive the Rental
            therefor, in which event Tenant shall pay to Landlord on demand the
            cost of renovating, repairing, and altering the Premises for a new
            Tenant or Tenants and any deficiency that may arise by

                                       18
<PAGE>

            reason of such reletting; provided, however, that Landlord shall
            have no duty to relet the Premises and Landlord's failure to relet
            the Premises shall not release or affect Tenant's liability for
            Rental or for damages.

      (d)   Do whatever Tenant is obligated to do under this Lease and may enter
            the Premises without being liable to prosecution or any claim for
            damages therefor, to accomplish this purpose. Tenant shall reimburse
            Landlord immediately upon demand for any expenses which Landlord
            incurs in thus effecting compliance with this Lease on Tenant's
            behalf, and Landlord shall not be liable for any damages suffered by
            Tenant from such action, whether caused by the negligence of
            Landlord or otherwise.

Section 24.03 No act or thing done by Landlord or its agents during the Term
shall constitute an acceptance of an attempted surrender of the Premises, and no
agreement to accept a surrender of the Premises or to terminate this Lease shall
be valid unless made in writing and signed by Landlord. No re-entry or taking
possession of the Premises by Landlord shall constitute an election by Landlord
to terminate this Lease, unless a written notice of such intention is given to
Tenant Notwithstanding any such reletting or re-entry or taking possession,
Landlord may at any time thereafter terminate this Lease for a previous default.
Landlord's acceptance of Rental following an event of default hereunder shall
not be construed as a waiver of such event of default. No waiver by Landlord of
any breach of this Lease shall constitute a waiver of any other violation or
breach of any time of the terms hereof. Forbearance by Landlord to enforce one
or more of the remedies herein provided upon a breach hereof shall not
constitute a waiver of any other breach of the Lease.

Section 24.04 No provision of this Lease shall be deemed to have been waived by
Landlord unless such waiver is in writing and signed by Landlord. Nor shall any
custom or practice which may evolve between the parties in the administration of
the terms of this Lease be construed to waive or lessen Landlord's right to
insist upon strict performance of the terms of this Lease. The rights granted to
Landlord in this Lease shall be cumulative of every other right or remedy which
Landlord may otherwise have at law or in equity or by statue, and the exercise
of one or more rights or remedies shall not prejudice or impair the current or
subsequent exercise of other rights or remedies.

                          ARTICLE 25 - WAIVER BY TENANT

To the extent permitted by applicable law, Tenant waives for itself and all
claiming by, through, and under it, including creditors of all kinds

      (a)   any right and privilege which it or any of them may have under any
            present or future constitution, statute, or rule of law to redeem
            the Premises or to have a continuance of this Lease for the Term
            after termination of Tenant's right of occupancy by order or
            judgment of any court or by any legal process or writ, under the
            terms of this Lease, or after the termination of the Term as herein
            provided,

      (b)   the benefits of any present or future constitution, statute, or rule
            of law which exempts property form liability for debt or for
            distress for rent, and

      (c)   the provisions of law relating to notice and/or delay in levy of
            execution in case of eviction of a Tenant for non-payment of rent.

                          ARTICLE 26 - SECURITY DEPOSIT

The Security Deposit if any shall be held by Landlord, without interest, as
security for the performance of Tenant's obligations under this Lease. Landlord
may, without prejudice to any other remedy, use the Security Deposit to remedy
any default in any obligation of Tenant hereunder, and such use shall survive
the termination of this Lease, and Tenant shall promptly, on demand, restore the
Security Deposit to its original amount. If Tenant is not in default at the
termination of this Lease, any remaining portion of the Security Deposit shall
be returned to Tenant. If Landlord transfers its interest in the Premises during
the Term, Landlord shall assign the Security Deposit to the transferee who shall
then become obligated to Tenant for its return, and thereafter Landlord shall
have no further liability for its return.

                 ARTICLE 27 - ATTORNEY'S FEES AND LEGAL EXPENSES

In any action or proceeding brought by either party against the other with
respect to this Lease, the prevailing party shall be entitled to recover from
the other party's reasonable attorneys' fees, investigation costs, and other
legal expenses and court costs incurred by such party in such action or
proceeding as the court may find to be reasonable. The prevailing party shall be
the one who receives the net judgment in its behalf at the end of any action.

rules, and governmental regulations relative to its right to do business in the

any ground or underlying Lease, any lender shall request reasonable
modifications in the Lease as a condition for such financing, Tenant will not

modifications do not increase the obligations of Tenant hereunder or materially
adversely affect either the Leasehold interest hereby created or Tenant's use
and enjoyment of the Premises.

Section 29.15 This Lease shall be governed by and construed under the laws of
the Commonwealth of Pennsylvania. Any action brought to enforce or interpret
this Lease shall be brought in the court of appropriate jurisdiction in
Cumberland County, Pennsylvania. Should any provision of this Lease require
judicial interpretation, it is agreed that the Court interpreting or considering
same shall not apply the presumption that the terms hereof shall be more
strictly construed against a party by reason of the rule or conclusion that a
document should be construed more strictly against the party who itself or
through its agent prepared the same, it being agreed that all parties hereto
have participated in the preparation of this Lease and that legal counsel was
consulted by each party before the execution of this Lease.

emergencies) enter upon the Premises at reasonable hours to inspect same or
clean or make repairs or alterations (but without any obligation to do so,
except as expressly provided for herein) and to show the Premises to prospective
lenders or purchasers, and, during the last 6 months of the Term of the Lease,
to show them to prospective Tenants at reasonable hours and, if they are
vacated, to prepare them for re-occupancy. Landlord shall cause its officers,
agents and representatives to exercise care with any such entry not to
unreasonably interfere with the operation and normal office routine of Tenant
(except in the case of emergency).

Section 29.18 Landlord may elect to relocate Tenant to other space in the
Building containing at least the same amount of Rentable Area as contained in
the Premises ("Substitution Space"). If such relocation occurs, the description
of the Premises set forth in this Lease shall, without further act on the part
of Landlord or Tenant, be deemed amended so that the Substitution Space shall be
deemed the Premises hereunder, and all of the terms, covenants, conditions and
provisions of this Lease shall continue in full force and effect and shall apply
to the Substitution Space. The cost of relocating Tenant and altering the
Substitution Space to make it comparable to the Premises shall be borne by
Landlord. The Annual Base Rental for the Substitution Space shall be the amount
specified under item 14 of the Basic Lease Information.

Section 29.19 The Exhibits and numbered riders attached to this Lease are by
this reference incorporated fully herein. The term "this Lease" shall be
considered to include all such Exhibits and riders.
