                                WITNESSETH, THAT:

      1. DEMISED PREMISES. Landlord, for the Term and subject to the provisions
and conditions hereof, leases to Tenant and Tenant accepts from Landlord, the
Demised Premises, together with the non-exclusive right to use the common areas
and facilities of the Buildings in common with the other tenants of the
Building. Tenant shall not use or occupy, or permit or suffer to be used or
occupied, the Demised Premises or any part thereof, other than for the Permitted
Use.

      2. TERM.

            (a) The first lease year of the Term shall commence on the
Commencement Date and shall end on (i) the day immediately preceding the first
anniversary of the Commencement Date, if the Commencement Date is the first day
of the month, or (ii) the last day of the month in which the first anniversary
of the Commencement Date occurs, if the Commencement Date is any day other than
the first day of a calendar month. Each lease year after the first lease year
shall be a consecutive twelve (12) month period commencing on the first day of
the calendar month immediately following the preceding lease year.

            (b) Tenant shall have the right and option to extend the Term for
two (2) additional periods of three (3) years (the "Extension Terms") commencing
upon the expiration of the original Term referred to in the Fundamental Lease
Provisions, provided that Tenant shall give Landlord notice of Tenant's
irrevocable exercise of such option at least six (6) months prior to the
expiration of the then current Term and provided further that Tenant shall not
be in default at either the time of giving such notice or at the time of the
commencement of the Extension Term in the performance or observance of any of
the terms and provisions of this Lease on the part of the Tenant to be performed
or observed. Prior to the exercise by Tenant of such option, the expression
"Term" shall mean the then current Term as may have been previously extended,
and after the exercise by Tenant of such option, the expression "Term" shall
mean the Term as it has been extended by the applicable Extension Term. Except
as expressly otherwise provided in the following paragraph, all the terms,
covenants, conditions, provisions and agreements in the Lease contained shall be
applicable to the Extension Term. If Tenant shall give notice of its exercise of
said option to extend in the manner and within the time period provided
aforesaid, the Term shall be extended upon the giving of such notice without the
requirement of any further action on the part of either Landlord or Tenant.

            (c) The Annual Base Rent payable during an Extension Term shall be
the greater of: the Fair Market Rent for the Demised Premises, as determined
below, for the applicable Extension Term, and (ii) the Annual Base Rent in
effect during the final lease year of the then current Term. As used herein, the
term "Fair Market Rent" shall mean the average of the annual rental rates then
being charged for comparable space in the Building or, if no comparable space
exists in the Building, for "Class A" office space in the Conshohocken market,
for leases commencing on or about the commencement of the Extension Term, taking
into consideration the use, location and floor level of the applicable building,
leasehold improvements or allowances provided, rental concessions, the term of
the lease under consideration, the extent of services provided thereunder, the
creditworthiness of Tenant, and other adjustments to the base rental and any
other relevant term or condition in making such evaluation. Landlord shall
determine the Fair Market Rent using its good faith judgment and shall provide
written notice of such rate within fifteen (15) days after Tenant's exercise
notice pursuant to this Section. Tenant shall thereupon have the following
options: (i) to accept such


                                       5
<PAGE>

proposed "Fair Market Rent", (ii) to decline to exercise its renewal option, or
(iii) to notify Landlord in writing that Tenant objects to the proposed rental
rate. Tenant must provide Landlord with written notification of its election
within fifteen (15) days after Tenant's receipt of Landlord's notice, otherwise
Tenant shall be deemed to have elected clause (ii) above, in which event Tenant
shall be deemed to have rescinded its exercise notice and this Lease shall
expire on the Expiration Date as if Tenant had not elected to exercise its
renewal option hereunder. If Tenant objects to Landlord's proposed "Fair Market
Rent" in accordance with clause (iii) above, Landlord and Tenant shall attempt
to negotiate a mutually acceptable rental rate within fifteen (15) days
following notification by Tenant, and if such negotiations have not been
concluded within such fifteen (15) day period, either party may require
determination of the Fair Market Rent for the Extension Term by giving written
notice to the other no later than ten (10) days after the expiration of such
fifteen (15) day period, which notice shall designate a reputable, independent
real estate appraiser, broker or consultant experienced in office leasing in the
local metropolitan area, each of which, for purposes of this Section, is
referred to as an "appraiser." Within ten (10) days after receipt of such
notice, the other party to this Lease shall select an appraiser meeting the
aforesaid requirements and give written notice of such selection to the
initiating party. If the two (2) appraisers fail to agree upon the Fair Market
Rent within ten (10) days after selection of the second appraiser, the two (2)
appraisers shall select a third (3rd) appraiser meeting the foregoing
requirements to determine the Fair Market Rent within ten (10) days after the
appointment of the third (3rd) appraiser. The Fair Market Rent applicable to the
Extension Term shall equal the arithmetic average of such three (3)
determinations; provided, however, that if one (1) appraiser's determination
deviates by more than five percent (5%) from the median of the three (3)
determinations, the Fair Market Rent shall be an amount equal to the average of
the other two (2) determinations. The determination of Fair Market Rent shall be
final, binding and conclusive on Landlord and Tenant

      3. TENANT IMPROVEMENTS.

            (a) Landlord, at its sole expense, shall (i) complete construction
of the bathrooms on the third and fourth floors of the Building (including one
(1) shower per bathroom) and (ii) install all main trunk lines for the HVAC
systems in the Demised Premises, each in accordance with Building standards
(collectively, the "Landlord's Work"). Except for the Landlord's Work Landlord
shall have no obligation to perform any improvements to the Demised Premises to
prepare the space for Tenant's occupancy, and Tenant acknowledges that Tenant
has inspected the Demised Premises and accepts the same in its "AS IS"
condition, without any representation or warranty by Landlord.

            (b) Except for the Landlord's Work, Tenant shall perform, at its
sole cost and expense, all work which Tenant deems necessary or desirable to
prepare the space for Tenant's initial occupancy (collectively, the "Tenant
Improvements"), which Tenant Improvements shall be subject to the prior written
approval of Landlord. All work shall be performed in a good and workmanlike
manner and in accordance with all applicable laws. Prior to the commencement of
any work within the Demised Premises, Tenant shall submit to Landlord, for
Landlord's prior approval, proposed plans and specifications (the "Proposed
Tenant's Plans") for Tenant's proposed improvements to the Demised Premises,
which plans shall be prepared by a registered architect licensed to do business
within the State in which the Property is located. The Proposed Tenant's Plans
shall include all information and specifications necessary for Landlord to fully
review the work described therein and shall conform to all applicable laws and
requirements of public authorities and insurance underwriters' requirements.
Landlord shall review and either approve or disapprove of the Proposed Tenant's
Plans within five (5) business days after receipt thereof from Tenant. If
Landlord disapproves the Proposed Tenant's


                                       6
<PAGE>

Plans, Landlord shall state specifically the reasons for such disapproval, and
Tenant shall cause its architects to promptly make any changes in the Proposed
Tenant's Plans reasonably required by Landlord. All contractors utilized by
Tenant for the performance of the Tenant Improvements shall be subject to the
prior written approval of Landlord.

            (c) All subsequent changes in the Tenant's Plans shall be subject to
the approval of Landlord. If Landlord approves any change in the Tenant's Plans,
Tenant shall construct, at Tenant's sole cost and expense, the Tenant
Improvements in accordance with such change.

            (d) Provided that Tenant is not in default of any of its obligations
hereunder, Landlord shall provide Tenant with a construction allowance (the
"Tenant Improvement Allowance") of Thirteen Dollars ($13.00) per rentable square
foot of the Demised Premises, which shall be applied solely against Tenant's
Costs for the Tenant Improvements and for no other purpose. The Tenant
Improvement Allowance shall be payable on the Commencement Date. "Tenant's
Costs" shall mean Tenant's out-of-pocket contract or purchase price(s) for
materials, components, labor and services incurred by tenant in connection with
the Tenant Improvements. Prior to payment of the Tenant Improvement Allowance,
the total amount of Tenant's Costs shall be subject to examination by Landlord,
and Tenant shall provide Landlord with copies of all invoices and other backup
documentation reasonably requested by Landlord relative thereto. In the event
that Tenant's Costs exceed the amount of the Tenant Improvement Allowance,
Tenant shall be solely responsible for such excess costs.

            (e) Landlord acknowledges that Tenant shall have the right to use
any existing materials currently located within the Demised Premises as of the
date hereof in connection with its build-out of the Tenant Improvements.

      4. DELAY IN POSSESSION. INTENTIONALLY OMITTED.

      5. RENT.

            (a) During the Term of this Lease, Tenant shall pay to Landlord the
Annual Base Rent in the amount set forth in Section 10 of the Fundamental Lease
Provisions. Such Base Rent shall be payable in equal monthly installments in
advance on the first day of each calendar month.

            (b) The term "rent" as used in this Lease shall mean the Annual Base
Rent, Tenant's Share of Operating Expenses (including, without limitation,
Taxes) and all other additional rent or other sums payable by Tenant to Landlord
under this Lease, all of which shall be deemed "rent" for purposes of Landlord's
rights and remedies with respect thereto.

            (c) The first installment of rent shall be payable on the
Commencement Date. If the Term begins on a day other than the first day of a
month, rent from such day until the first day of the following month shall be
prorated on a per diem basis for each day of such partial month, and the
installment of rent paid at execution hereof shall be applied to the rent due
for the first full calendar month of the term hereof.

            (d) All rent and other sums due to Landlord hereunder shall be
payable to Landlord c/o Landlord's Property Manager at the address specified in
Section 12 of the Fundamental Lease Provisions, or to such other party or at
such other address as Landlord may designate, from time to time, by written
notice to Tenant, without demand and without deduction,


                                       7
<PAGE>

set-off or counterclaim (except to the extent demand, notice or set-off shall be
expressly provided for herein).

            (e) If Landlord, at any time or times, shall accept said rent or any
other sum due to it hereunder after the same shall become due and payable, such
acceptance shall not excuse delay upon subsequent occasions, or constitute or be
construed as, a waiver of any of Landlord's rights hereunder.

      6. SECURITY DEPOSIT/LETTER OF CREDIT.

            (a) As additional security for the full and prompt performance by
Tenant of the terms and covenants of this Lease, Tenant shall deliver to
Landlord simultaneously with the execution of this Lease an unconditional and
irrevocable letter of credit (the "Letter of Credit") in the amount of the
Security Deposit (as defined in Section 11 of the Fundamental Lease Provisions),
which Letter of Credit shall be in form and substance satisfactory to Landlord
and shall be issued by a bank satisfactory to Landlord. In such event, the first
such Letter of Credit shall expire no earlier than the first anniversary of the
Commencement Date and all subsequent Letters of Credit (which shall meet all of
the requirements set forth in the preceding sentence) shall expire no earlier
than twelve (12) months after the expiration of the then outstanding and
expiring Letter of Credit. Subject to subsection (b) below, Tenant shall ensure
at all times during the Term of this Lease, an unexpired Letter of Credit in the
face amount of the Security Deposit (as such amount may be reduced pursuant to
subparagraph (b) below) or cash in such amount shall be in the possession of
Landlord. During the Term, Tenant shall deliver a replacement Letter of Credit
to Landlord no later than thirty (30) days prior to the expiration date of the
then outstanding and expiring Letter of Credit; provided, however, that the
replacement Letter of Credit is not required to have an effective date sooner
than the expiration date of the then-existing Letter of Credit. Failure by
Tenant to deliver any replacement Letter of Credit as required above shall
entitle Landlord to draw upon the outstanding Letter of Credit and retain the
entire proceeds thereof for application as the Security Deposit hereunder.
Tenant shall not be entitled to interest for any period during which Landlord is
holding cash as the Security Deposit nor shall Landlord be required to keep such
cash Security Deposit separate from its general funds. Each Letter of Credit
shall be for the benefit of Landlord, its successors and assigns to draw from
time to time under the Letter of Credit in portions or in whole upon
presentation of a sight draft and statement by Landlord that Landlord is
entitled to draw thereunder pursuant to the terms and provisions of this Lease.
Landlord may assign and deliver the Letter of Credit to any purchaser or
successor of Landlord's interest in the Building, in which event Landlord shall
be discharged from any further liability with respect to the Letter of Credit.

            (b) Provided that Tenant is not then in default, the Security
Deposit shall be reduced by the amount of One Hundred Twenty Five Thousand
Dollars ($125,000.00) as of each of the first four (4) anniversaries of the
Commencement Date and, provided Tenant is not then in default, the Security
Deposit shall be reduced to Zero Dollars ($0.00) as of the commencement of the
fifth (5th) lease year.

            (c) If at any time during the Term, Tenant defaults in the
performance of any of its obligations hereunder, Landlord shall have the right
to draw upon the Letter of Credit ( or, if a cash Security Deposit, to apply
such cash) to satisfy such obligations including, without limitation, the
Accelerated Rent Component and any damages to which Landlord is entitled
pursuant to Section 15 hereof. If any portion of the Letter of Credit (or cash
Security Deposit) is used, applied or retained by Landlord, Tenant shall, upon
demand, reinstate the Letter of Credit or cash in the full amount of the
Security Deposit (and thereafter there shall be no further


                                       8
<PAGE>

reductions of the security Deposit pursuant to subparagraph (b) above), and
Tenant's failure to do so shall constitute a default under this Lease for which
Tenant shall not be entitled to notice or an opporturiity to cure The Security
Deposit shall not be construed as liquidated damages hereunder, and if
Landlord's claims hereunder exceed the amount of the Security Deposit, Tenant
shall remain liable for the balance of such claims.

annual amortized portion of such expense together with an interest factor equal
to the prime rate of interest as published from time to time in The Wall Street
Journal shall be included in annual Operating Expenses; (iii) Rentals for items
which if purchased, rather than rented, would constitute a capital cost; (iv)
any charge for depreciation, amortization and interest on encumbrances or ground

to the violation by Landlord or any tenant of the terms and conditions of any
lease of space in the Building; (xiii) intentionally omitted; (xiv) salaries and
other benefits paid to the employees of Landlord to the extent customarily
included in or covered by a management fee, provided that in no event shall
Operating Expenses include salaries and/or benefits attributable to personnel
above the level of Building manager; (xv) rent for any office space occupied by
Building management personnel to the extent the size or rental rate for of such
office space exceeds the size or fair market rental value of office space
occupied by management personnel of comparable buildings in the vicinity of the
Building; (xvi) amounts paid to Landlord or to subsidiaries or affiliates of
Landlord for goods and/or services in the Building to the extent the same
exceeds the costs of such goods and/or services rendered by unaffiliated third
parties on a competitive basis; (xvii) Landlord's general corporate overhead and
general and administrative expenses; (xviii) any compensation paid to clerks,
attendants or other persons in commercial concessions operated by Landlord;
(xix) intentionally omitted; (xx) costs incurred in connection with upgrading
the Building to correct any violation of any laws, rules, regulations and codes
in effect on the Commencement Date to the extent that such violation existed as
of the Commencement Date; (xxi) intentionally omitted; (xxii) costs arising from
the negligence or willful misconduct of Landlord or other tenants or occupants
of the Building or their respective agents, employees, licensees, vendors,
contractors or providers of materials or services; (xxiii) costs arising from
Landlord's charitable or political contributions; (xxiii) costs incurred for the
correction or repair of any defects in the original design and construction of
the Building; (xxiv) costs for sculpture, paintings or other objects of art; or
(xxv) costs associated with the operation of the business of the entity which
constitutes Landlord as the same are distinguished from the costs of operation
of the Building, including accounting and legal matters, costs of defending any
lawsuits with any mortgagee (except as the actions of Tenant may be in issue),
costs of selling, syndicating, financing, mortgaging or hypothecating any of
Landlord's interest in the Building, costs incurred in connection with any
disputes between Landlord and its employees, between Landlord and Building
management, or between Landlord and other tenants or occupants.

            (b) In determining Operating Expenses for any year, if less than
ninety-five percent (95%) of the Building rentable area shall have been occupied
by tenants at any time during such year, Operating Expenses shall be deemed for
such year to be an amount equal to the like expenses which Landlord reasonably
determines would normally had been incurred had such occupancy been ninety-five
percent (95%) throughout such year.

            (c) For and with respect to each calendar year of the Term
(including any renewals or extensions thereof), there shall accrue, as
additional rent, an amount ("Tenant's Share") equal to the positive difference,
if any, between (A) Tenant's Fraction of Operating


                                       10
<PAGE>

Expenses, minus (B) the Expense Stop (appropriately prorated for any partial
calendar year included within the beginning and end of the Term).

            (d) Landlord shall furnish to Tenant as soon as reasonably possible
after the beginning of each calendar year of the Term:

                  (i) A statement (the "Expense Statement") setting forth (1)
Operating Expenses for the previous calendar year, and (2) Tenant's Share of
Operating Expenses for the previous calendar year; and

                  (ii) A statement of Landlord's good faith estimate of
Operating Expenses, and the amount of Tenant's Share thereof (the "Estimated
Share"), for the current calendar year.

            (e) Within thirty (30) days after Tenant receives the Expense
Statement, Tenant shall pay to Landlord the difference, if positive, between the
Tenant's Share of Operating Expenses for such previous year and the actual
payments made by Tenant during such calendar year, or if the actual payments
exceed Tenant's Share of Operating Expenses for such previous year, Tenant shall
receive a credit against the next payment(s) of Operating Expenses falling due
or, if the Lease shall have expired, a refund of such overpayment delivered with
such Expense Statement.

            (f) Upon the written request of Tenant delivered to Landlord within
ninety (90) days after delivery of the Expense Statement, Landlord shall give
Tenant the opportunity during normal business hours to review Landlord's books
and records relating to Operating Expenses, provided Tenant thereafter
diligently and promptly completes such inspection, and such inspection privilege
shall not delay Tenant's obligation to pay on account all sums due pursuant to
such Expense Statement. Unless Tenant, within ninety (90) days after any Expense
Statement is furnished, shall give notice to Landlord that Tenant disputes said
statement, specifying in detail the basis for such dispute, each Expense
Statement furnished to Tenant by Landlord under this Section shall be
conclusively binding upon Tenant as to the Operating Expenses due from Tenant
for the period represented thereby; provided, however, that additional amounts
due may be required to be paid by any supplemental statement furnished by
Landlord. In the event that Tenant timely disputes such Expense Statement and
the dispute is not amicably resolved within ninety (90) days after Tenant's
notice of dispute, then either party may refer the dispute to an independent
certified public accounting firm mutually acceptable to Landlord and Tenant, and
the determination of such accounting firm shall be final, binding and conclusive
on Landlord and Tenant. Tenant agrees to pay for the cost of such audit by said
accounting firm unless it is determined that Landlord's original determination
of the actual Operating Expenses was in error by more than seven percent (7%),
in which event Landlord shall pay the cost of such audit. Pending resolution of
any dispute, Tenant shall pay the additional rent in accordance with the Expense
Statement furnished by Landlord.

            (g) Beginning with the next installment of Base Rent due after
delivery of the statement of Tenant's Estimated Share, Tenant shall pay to
Landlord, on account of its share of Operating Expenses, one-twelfth (1/12) of
the Estimated Share multiplied by the number of full or partial calendar months
elapsed during the current calendar year up to and including the month payment
is made (less any amounts previously paid by Tenant on account of Operating
Expenses for such period).


                                       11
<PAGE>

            (g) On the first day of each succeeding month up to the time Tenant
shall receive a new statement of Tenant's Estimated Share, Tenant shall pay to
Landlord, on account of its share of Operating Expenses, one-twelfth of the then
current Estimated Share. Any payment due from Tenant to Landlord on account of
Operating Expenses not yet determined as of the expiration of the Term shall be
made within thirty (30) days after submission to Tenant of the next Expense
Statement, which obligation shall survive the expiration or earlier termination
of this Lease.

      8. UTILITIES SEPARATELY CHARGED TO DEMISED PREMISES. Tenant shall be
responsible for all utilities (including gas and electric) which are consumed
within the Demised Premises. If a separate meter is installed, Tenant shall pay
for the consumption of such utilities based on its metered usage. If no meter is
installed, Tenant shall pay a pro-rata share of any utility charges covering the
Demised Premises and other areas of the Building, which pro-rata share shall be
based on the percentage which the Tenant's RSF bears to the square footage of
the areas of the Building serviced by such utility. Tenant shall pay all utility
bills within ten (10) days after receipt by Tenant. Landlord shall have the
right, to be exercised by written notice to Tenant, to direct Tenant to contract
directly with the utility provider supplying electricity to the Building, in
which event Tenant shall pay all charges therefor directly to the utility
provider, except that Landlord shall pay for any separate meter installation
required in connection such election by Landlord. Landlord shall at all times
have the exclusive right to select the provider(s) of utility service to the
Building and the Property; however, in the event that any telecommunications
supplier is able to supply telecommunications services directly to the Premises,
Tenant shall have the right to contract directly for such services at Tenant's
sole cost and expense.

      9. SERVICES. Landlord agrees that it shall:

            (a) Provide water for drinking, lavatory and toilet purposes drawn
through fixtures installed by Landlord;

            (b) Furnish heat, ventilation and air-conditioning to the Demised
Premises during Business Hours;

            (c) Furnish electricity to the Demised Premises for ordinary office
purposes, including general lighting and personal computers, provided, however,
that Landlord shall have no obligation to supply in excess of nine (9) watts per
rentable square foot of the Demised Premises;

            (d) Provide janitorial services in accordance with Landlord's
building standard janitorial specifications, attached hereto as Exhibit "D". Any
and all additional or specialized janitorial service desired by Tenant shall be
contracted for by Tenant directly and the cost and payment thereof shall be the
sole responsibility of Tenant; and

            (e) Provide Tenant with standard signage on the directory in the
Building lobby.

            The cost of the foregoing services shall be included in Operating
Expenses. It is understood that Landlord does not warrant that any of the
services referred to in this Section will be free from interruption from causes
beyond the reasonable control of Landlord. No interruption of service shall ever
be deemed an eviction or disturbance of Tenant's use and possession of the
Demised Premises or any part thereof or render Landlord liable to Tenant for
damages, permit Tenant to abate rent or otherwise relieve Tenant from
performance of Tenant's


                                       12
<PAGE>

obligations under this Lease. Notwithstanding the foregoing, in the event that
any interruption of utilities caused by Landlord's negligence renders the
Demised Premises untenantable for a period of five (5) or more consecutive
business days after written notice thereof to Landlord, then, to the extent
that the Demised Premises are rendered untenantable, Tenant shall be entitled to
a proportionate abatement of rent until such time as the Demised Premises are
thereafter rendered tenantable.

      10. CARE OF DEMISED PREMISES. Tenant agrees, on behalf of itself, its
employees and agents that it shall:

            (a) Comply at all times with any and all federal, state and local
statutes, regulations, ordinances, and other requirements of any of the
constituted public authorities relating to its use and occupancy of the Demised
Premises.

            (b) Give Landlord access to the Demised Premises at all reasonable
times and upon reasonable notice (except in the event of emergency), without
charge or diminution of rent, to enable Landlord (i) to examine the same and to
make such repairs, additions and alterations as Landlord may be permitted to
make hereunder or as Landlord may deem advisable for the preservation of the
integrity, safety and good order of the Building or any part thereof; and (ii)
to show the Demised Premises to prospective mortgagees and purchasers and,
during the six (6) months prior to expiration of the Term, to prospective
tenants;

            (c) Reasonable wear and tear and damage by casualty excepted,
maintain, repair and replace the interior, non-structural portions of the
Demised Premises in good order and repair as and when needed, and replace all
glass broken by Tenant, its agents, employees or invitees with glass of the same
quality as that broken, except for glass broken by fire and extended
coverage-type risks, and commit no waste in the Demised Premises;

            (d) Upon the expiration or earlier termination of this Lease, remove
Tenant's goods and effects and those of any other person claiming under Tenant,
and quit and deliver up the Demised Premises to Landlord peaceably and quietly
in as good order and condition as existed at the inception of the Term, together
with any alterations approved by Landlord, reasonable wear and tear, damage from
fire and casualty excepted. Goods and effects not removed by Tenant at the
termination of this Lease, however terminated, shall be considered abandoned
and Landlord may dispose of and/or store the same as it deems expedient, the
cost thereof to be charged to Tenant;

            (e) Not place signs on the Demised Premises except for (i) signs
located entirely within the Demised Premises and which are not visible from the
exterior of the Demised Premises, and (ii) signs on doors provided that the
lettering and text are reasonably approved by Landlord;

            (f) Not overload, damage or deface the Demised Premises or do any
act which might make void or voidable any insurance on the Demised Premises or
the Building or which may render an increased or extra premium payable for
insurance (and without prejudice to any right or remedy of Landlord regarding
this subparagraph, Landlord shall have the right to collect from Tenant, upon
demand, any such increase or extra premium). Tenant shall maintain at its own
sole cost adequate insurance coverage for the full replacement value of all of
its


                                       13
<PAGE>

equipment, furniture, supplies and fixtures and provide Landlord with
certificates evidencing such coverage;

            (g) Not make any alteration of or addition to the Demised Premises
without the prior written approval of Landlord which approval shall not be
unreasonably withheld or delayed. Tenant shall not be required to obtain the
approval of Landlord for interior, nonstructural alterations of a decorative
nature that do not exceed, more than $50,000 in the aggregate;

            (h) Not install any equipment of any kind whatsoever which might
necessitate any changes, replacements or additions to any of the heating,
ventilating, air-conditioning, electric, sanitary, elevator or other systems
serving the Demised Premises or any other portion of the Building, or to any of
the services required of Landlord under this Lease, without the prior written
approval of Landlord, which approval shall not be unreasonably withheld or
delayed. In the event such consent is granted, such replacements, changes or
additions shall be paid for by Tenant at Tenant's sole cost and expense. If
Landlord notifies Tenant at the time of such approval that Landlord shall so
require, then at the expiration or earlier termination of this Lease, Tenant
shall pay Landlord's cost of restoring such systems to their condition prior to
such replacements, changes or additions;

            (i) Not install or authorize the installation of any coin operated
vending machine, except for the dispensing of cigarettes, coffee, and similar
items to the employees of Tenant for consumption upon the Demised Premises; and

            (j) Observe the rules and regulations annexed hereto as Exhibit "C,"
as Landlord may from time to time amend the same, for the general safety,
comfort and convenience of Landlord, occupants and tenants of the Building.

      11. MECHANIC'S LIEN. Tenant shall, within ten (10) days after notice from
Landlord, discharge any mechanic's lien for materials or labor claimed to have
been furnished to the Demised Premises on Tenant's behalf (except for work
contracted for by Landlord) and shall indemnify and hold harmless Landlord from
any loss incurred in connection therewith.

      12. REPAIRS AND MAINTENANCE. Landlord shall keep and maintain the public
areas of the Building clean and in good working order. Landlord shall further
make, or cause to be made, all necessary repairs to the structure and exterior
of the Building, as well as to the mechanical, HVAC, electrical and plumbing
systems servicing Building. The cost of the foregoing maintenance and repairs
shall be included in Operating Expenses to the extent set forth herein.
Notwithstanding the foregoing, all repairs made necessary by Tenant's specific
use, occupancy or alteration of the Building, or by the negligent acts of
Tenant, its agents, employees or invitees, shall be made at the sole cost and
expense of Tenant.

      13. SUBLETTING AND ASSIGNING.

            (a) Tenant shall not assign this Lease or sublet all or any portion
of the Demised Premises, whether voluntarily or by operation of law, without
first obtaining Landlord's prior written consent thereto, which consent shall
not be unreasonably withheld, conditioned or delayed Tenant acknowledges that it
shall be reasonable for Landlord to withhold its consent if, inter alia, the
reputation or financial responsibility of a proposed assignee or subtenant is
unsatisfactory to Landlord, or if the proposed sublease or assignment is to a
tenant of the Building and alternative space is available for lease in the
Building, or if such subtenant's or assignee's


                                       14
<PAGE>

business is not consonant with that of the other tenants of the Building. In
addition, Tenant shall not mortgage, pledge or hypothecate this Lease. Any
assignment, sublease, mortgage, pledge or hypothecation in violation of this
Section shall be void at the option of Landlord and shall constitute a default
hereunder without the opportunity for notice or cure by Tenant. Landlord
acknowledges that Tenant intends to initially sublet up to 21,000 square feet in
the Premises; Landlord agrees that it shall not unreasonably withhold, condition
or delay its consent to such initial subletting.

            (b) Subject to the provisions of the following sentence, a transfer
or sale by Tenant of a majority of the voting shares, partnership interests or
other controlling interests in Tenant shall be deemed an assignment of this
Lease by Tenant requiring Landlord's prior written consent pursuant to
subparagraph (a) above. Notwithstanding the foregoing, so long as Tenant is not
in default under this Lease, Tenant shall have the right, without Landlord's
consent, to sublet all or a portion of the Demised Premises or to assign the
Lease to any company which (i) is an Affiliate of Tenant, or (ii) merges with,
combines with or is the result of such combination, or purchases all or
substantially all the assets or a majority of the voting shares or interests of
Tenant, provided that after such merger, combination or purchase such entity has
a net worth not less than the then net worth of Tenant immediately prior to such
merger, combination or purchase. As used herein, "Affiliate" shall mean any
corporation which controls, is controlled by or is under common control with
Tenant, and "control" shall mean the direct ownership of more than fifty percent
(50%) of the voting shares, partnership interests or other controlling interests
of the applicable entity. Tenant shall deliver to Landlord written notice of
such assignment or subletting promptly upon the consummation of any such
transaction. The public issuance or trading of shares in Tenant shall not be
construed as affecting the assignment of this Lease.

            (c) Notwithstanding the foregoing, no subletting or assignment with
or without Landlord's consent shall in any way relieve or release Tenant from
liability for the performance of all terms, covenants and conditions of this
Lease. Furthermore, no assignment will be valid unless the assignee shall
execute and deliver to Landlord an assumption of liability agreement in form
satisfactory to Landlord, including an assumption by the assignee of all of the
obligations of Tenant and the assignee's ratification of and agreement to be
bound by all the provisions of this Lease, and no subletting will be valid
unless Landlord shall have approved the sublease in writing, which sublease must
include a provision by which the subtenant agrees to be bound by the
incorporation of applicable provisions of this Lease.

            (d) Tenant shall pay to Landlord, as additional rent hereunder, 50%
of all subrents or other sums or economic consideration received by Tenant
(after deducting Tenant's reasonable costs of reletting, including but not
limited to commissions, legal fees, tenant improvements and concessions),
whether denominated as rentals or otherwise, in excess of the monthly sums which
Tenant is required to pay under this Lease.

      14. FIRE OR CASUALTY. In the event that the whole or a substantial part of
the Building or the Demised Premises is damaged or destroyed by fire or other
casualty, then, within forty-five (45) days after the date that Landlord
receives notice of such fire or other casualty, Landlord shall provide written
notice to Tenant as to whether Landlord intends to repair or rebuild and the
estimated time period for the completion thereof. In the event that Landlord's
notice provides that the repairs to the Demised Premises shall require more than
two hundred seventy (270) days to complete, then Tenant shall have the right to
terminate this Lease by providing written notice thereof to Landlord within
thirty days (30) after receipt of Landlord's notice. In the event that Landlord
elects to repair or rebuild (and Tenant does not have the right to, or has
elected not to, terminate this Lease in accordance with the foregoing


                                       15
<PAGE>

sentence), Landlord shall thereupon cause the damage (excepting, however,
Tenant's furniture, fixtures, equipment and improvements, which shall be
Tenant's responsibility to restore) to be repaired with reasonable speed,
subject to delays beyond the reasonable control of Landlord. In the event the
damage shall be so extensive that Landlord shall decide not to repair or
rebuild, or if any mortgagee, having the right to do so, shall direct that the
insurance proceeds are to be applied to reduce the mortgage debt rather than to
the repair of such damage, this Lease shall, be terminated effective as of the
date of casualty. To the extent and for the time that the Demised Premises are
rendered untenantable on account of fire or other casualty, the rent shall
proportionately abate.

      15. EMINENT DOMAIN. If the whole or a substantial part of the Building is
taken or condemned for a public or quasi-public use under any statute or by
right of eminent domain by any competent authority or sold in lieu of such
taking or condemnation, such that in the opinion of Landlord the Building is not
economically operable as before without substantial alteration or
reconstruction, this Lease shall automatically terminate on the date that the
right to possession shall vest in the condemning authority (the "Taking Date"),
with rent being adjusted to said Taking Date, and Tenant shall have no claim
against Landlord for the value of any unexpired term of this Lease. Tenant shall
have no claim against Landlord and no claim or right to any portion of any
amount that may be awarded as damages or paid as a result of any taking,
condemnation or purchase in lieu thereof; all rights of Tenant thereto are
hereby assigned by Tenant to Landlord. If any part of the Demised Premises is so
taken or condemned, this Lease shall automatically terminate as to the portion
of the Demised Premises so taken or condemned, as of the Taking Date, and this
Lease shall continue in full force as to the remainder of the Demised Premises,
with rent abating only to the extent of the Demised Premises so taken or
condemned; provided, however, that if the remaining portion of the Demised
Premises is no longer suitable for the Permitted Use, then Tenant shall have the
right to terminate this Lease by providing written notice thereof to Landlord
within thirty (30) days after the Taking Date. Nothing in this section shall be
construed to prevent Tenant from filing a separate claim with the condemning
authority for Tenant's costs and losses associated with any such taking,
provided that the same does not diminish or otherwise adversely affect any claim
by Landlord.

      16. INSOLVENCY. (a) The appointment of a receiver or trustee to take
possession of all or a portion of the assets of Tenant, or (b) an assignment by
Tenant for the benefit of creditors, or (c) the institution by or against Tenant
of any proceedings for bankruptcy or reorganization under any state or federal
law (unless in the case of involuntary proceedings, the same shall be dismissed
within sixty (60) days after institution), or (d) any execution issued against
Tenant which is not stayed or discharged within thirty (30) days after issuance
of any execution sale of the assets of Tenant, shall constitute a breach of this
Lease by Tenant. Landlord in the event of such a breach, shall have, without
need of further notice, the rights enumerated in Section 17 herein.

      17. DEFAULT.

            (a) If Tenant shall fail to pay rent or any other sum payable to
Landlord hereunder when due and such failure continues for more than five
business (5) days after written notice thereof from Landlord to Tenant
(provided, however, that Landlord shall not be required to provide notice to
Tenant more than two times during any twelve month period), or if Tenant shall
fail to perform or observe any of the other covenants, terms or conditions
contained in this Lease and such failure continues for more than thirty (30)
days after written notice thereof from Landlord (or such longer period as is
reasonably required to correct any such default, provided Tenant promptly
commences and diligently continues to effectuate a cure, but in any


                                       16
<PAGE>

event within ninety (90) days after written notice thereof by Landlord), or if
any of the events specified in Section 16 occur, or if Tenant abandons the
Demised Premises during the term hereof or removes or manifests an intention to
remove any of Tenant's goods or property therefrom other than in the ordinary
and usual course of Tenant's business, then and in any of said cases
(notwithstanding any former breach of covenant or waiver thereof in a former
instance), Landlord, in addition to all other rights and remedies available to
it by law or equity or by any other provisions hereof, may at any time
thereafter:

                  (i) upon three (3) days notice to Tenant, declare to be
immediately due and payable, a sum equal to the Accelerated Rent Component (as
hereinafter defined), and Tenant shall remain liable to Landlord as hereinafter
provided; and/or

                  (ii) whether or not Landlord has elected to recover the
Accelerated Rent Component, terminate this Lease on at least five (5) days
notice to Tenant and, on the date specified in said notice, this Lease and the
term hereby demised and all rights of Tenant hereunder shall expire and
terminate and Tenant shall thereupon quit and surrender possession of the
Demised Premised to Landlord in the condition elsewhere herein required and
Tenant shall remain liable to Landlord as hereinafter provided.

            (b) For purposes herein, the Accelerated Rent Component shall mean
the aggregate of:

                  (i) all rent and other charges, payments, costs and expenses
due from Tenant to Landlord and in arrears at the time of the election of
Landlord to recover the Accelerated Rent Component; and

                  (ii) the Annual Base Rent reserved for the then entire
unexpired balance of the Term (taken without regard to any early termination of
the term by virtue of any default), plus all other charges, payments, costs and
expenses herein agreed to be paid by Tenant up to the end of the Term which
shall be capable of precise determination at the time of Landlord's election to
recover the Accelerated Rent Component, discounted to present value based upon a
then commercially reasonable discount rate; and

                  (iii) Landlord's good faith estimate of all charges, payments,
costs and expenses herein agreed to be paid by Tenant up to the end of the Term
which shall not be capable of precise determination as aforesaid (and for such
purposes no estimate of any component of the additional rent to accrue pursuant
to the provisions of Section 4 and Section 5 hereof shall be less than the
amount which would be due if each such component continued at the highest
monthly rate or amount in effect during the twelve (12) months immediately
preceding the default), discounted to present value based upon a then
commercially reasonable discount rate.

            (c) In any case in which this Lease shall have been terminated, or
in any case in which Landlord shall have elected to recover the Accelerated Rent
Component and any portion of such sum shall remain unpaid, Landlord may without
further notice, enter upon and repossess the Demised Premises by any lawful
means, and may dispossess Tenant and remove Tenant and all other persons and
property from the Demised Premises and may have, hold and enjoy the Demised
Premises and the rents and profits therefrom. Landlord may, either in its own
name or as agent for Tenant, if this Lease has not been terminated, or in its
own behalf, if this Lease has been terminated, relet the Demised Premises or any
part thereof for such term or terms (which may be greater or less than the
period which would otherwise have constituted the balance of the Term) and on
such terms (which may include concessions of free


                                       17
<PAGE>

rent) as Landlord in its sole discretion may determine. Landlord may, in
connection with any such reletting, cause the Demised Premises to be decorated,
altered, divided, consolidated with other space or otherwise changed or prepared
for reletting. No reletting shall be deemed a surrender and acceptance of the
Demised Premises.

            (d) In the event Landlord shall, after default or breach by Tenant,
recover the Accelerated Rent Component from Tenant and it shall be determined at
the expiration of the Term of this Lease (taken without regard to early
termination for default) that a credit is due Tenant because the net proceeds of
reletting, as aforesaid, plus amounts paid to Landlord by Tenant exceed the
aggregate of rent and other charges accrued in favor of Landlord to the end of
the Term of this Lease, Landlord shall refund such excess to Tenant, without
interest, promptly after such determination.

            (e) In the event that Landlord shall, after default or breach by
Tenant, recover the Accelerated Rent Component and/or retake possession of the
Demised Premises and/or terminate this Lease, then Landlord agrees to use
reasonable efforts to relet the Demised Premises; provided, however, in no event
shall Landlord be required to (i) lease the Demised Premises over other
available space in the Building, (ii) accept a below-market rental rate for the
Demised Premises, (iii) accept any tenant whose creditworthiness is
unsatisfactory to Landlord, in its sole discretion, or (iv) accept any tenant
whose business is not compatible with the other tenants of the Building, as
determined by Landlord in its sole discretion.

            (f) As an alternative remedy of Landlord in the event of termination
of this Lease by Landlord following any breach or default by Tenant, Landlord,
at its option, shall be entitled to recover damages for such breach in an amount
equal to the Accelerated Rent Component (determined from and after the date of
Landlord's election under this subsection (f)) less the fair rental value of the
Demised Premises for the remainder of the term of this Lease (taken without
regard to the early termination) and such damages shall be payable by Tenant
upon demand. Nothing contained in this Lease shall limit or prejudice the right
of Landlord to prove and obtain as damages incident to a termination of this
Lease, in any bankruptcy reorganization or other court proceedings, the maximum
amount allowed by any statute or rule of law in effect with such damages are to
be proved.

            (g) AFTER A DEFAULT OR THE EXPIRATION OF THE TERM, FOR THE PURPOSE
OF OBTAINING POSSESSION OF THE DEMISED PREMISES, TENANT HEREBY AUTHORIZES AND
EMPOWERS THE PROTHONOTARY OR ANY ATTORNEY OF ANY COURT OF RECORD IN THE
COMMONWEALTH OF PENNSYLVANIA OR ELSEWHERE, AS ATTORNEY FOR TENANT AND ALL
PERSONS CLAIMING UNDER OR THROUGH TENANT, TO APPEAR FOR AND CONFESS JUDGMENT
AGAINST TENANT FOR POSSESSION OF THE DEMISED PREMISES, AND AGAINST ALL PERSONS
CLAIMING UNDER OR THROUGH TENANT, IN FAVOR OF LANDLORD, FOR RECOVERY BY LANDLORD
OF POSSESSION THEREOF, FOR WHICH THIS AGREEMENT OR A COPY HEREOF VERIFIED BY
AFFIDAVIT, SHALL BE A SUFFICIENT WARRANT; AND THEREUPON A WRIT OF POSSESSION MAY
IMMEDIATELY ISSUE FOR POSSESSION OF THE DEMISED PREMISES, WITHOUT ANY PRIOR WRIT
OR PROCEEDING WHATSOEVER AND WITHOUT ANY STAY OF EXECUTION. IF FOR ANY REASON
AFTER SUCH ACTION HAS BEEN COMMENCED THE SAME SHALL BE TERMINATED AND THE
POSSESSION OF THE DEMISED PREMISES REMAINS IN OR IS RESTORED TO TENANT, LANDLORD
SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT TO CONFESS JUDGMENT IN ONE OR
MORE FURTHER ACTIONS IN THE MANNER AND FORM SET FORTH ABOVE TO RECOVER
POSSESSION OF SAID DEMISED PREMISES FOR SUCH SUBSEQUENT


                                       18
<PAGE>

DEFAULT. TENANT WAIVES ALL ERRORS IN CONNECTION WITH ANY SUCH CONFESSION OF
JUDGMENT. NO SUCH TERMINATION OF THIS LEASE, NOR TAKING, NOR RECOVERING
POSSESSION OF THE DEMISED PREMISES SHALL DEPRIVE LANDLORD OF ANY REMEDIES OR
ACTION AGAINST TENANT FOR RENT OR FOR DAMAGES DUE OR TO BECOME DUE FOR THE
BREACH OF ANY CONDITION OR COVENANT HEREIN CONTAINED, NOR SHALL THE BRINGING OF
ANY SUCH ACTION FOR RENT, OR BREACH OF COVENANT OR CONDITION NOR THE RESORT TO
ANY OTHER REMEDY HEREIN PROVIDED FOR THE RECOVERY OF RENT OR DAMAGES FOR SUCH
BREACH BE CONSTRUED AS A WAIVER OF THE RIGHT TO INSIST UPON THE FORFEITURE AND
TO OBTAIN POSSESSION IN THE MANNER HEREIN PROVIDED.

            (h) [intentionally omitted]

            (i) Tenant hereby waives all errors and defects of a procedural
nature in any proceedings brought against it by Landlord under this Lease.
Tenant further waives the right to any notices to quit as may be specified by
applicable law, and agrees that five business (5) days notice shall be
sufficient in any case where a longer period may be statutorily specified.

            (j) If rent or any other sum due from Tenant to Landlord shall be
overdue for more than five business (5) days after written notice from Landlord,
it shall thereafter bear interest until paid at the rate of the lesser of (x)
seven percent (7%) above the then prime rate published in the Wall Street
Journal or (y) the highest legal rate.

            (k) Landlord shall be deemed to be in default of this Lease if
Landlord fails to make any payments to Tenant required under this Lease and such
failure continues for ten (10) business days after written notice from Tenant to
Landlord, or if Landlord shall be in default in the prompt and full performance
of any other of its material promises, covenants or agreements contained in this
Lease and such default in performance continues for more than thirty (30) days
after written notice thereof from Tenant to Landlord specifying the particulars
of such default or breach of performance; provide, however, that if the default
complained of, other than for the payment of monies, is of such a nature that
the same cannot reasonably be rectified or cured within such thirty (30) day
period, then such default shall be deemed to be rectified or cured if Landlord,
within such thirty (30) day period, shall have commenced such cure and shall
continue thereafter with due diligence to cause such cure to be completed. Upon
any default of this Lease by Landlord, Tenant shall be entitled to pursue any
and all remedies available to Tenant at law or in equity.

      18. LANDLORD'S RIGHT TO CURE. Landlord may (but shall not be obligated),
on five (5) business days notice to Tenant (except that no notice need be given
in case of emergency) cure on behalf of Tenant any default hereunder by Tenant,
and the cost of such cure (including any attorney's fees incurred) shall be
deemed additional rent payable upon demand.

      19. INSURANCE. (a) Tenant shall at all times during the Term, including
any renewal or extension thereof, maintain in full force and effect with respect
to the Demised Premises and Tenant's use thereof, (i) comprehensive public
liability insurance, covering injury to person and property in amounts at least
equal to Two Million Dollars ($2,000,000) per occurrence and annual aggregate
limit for bodily injury and One Million Dollars ($1,000,000) per occurrence and
annual aggregate limit for property damage, with increases in such limits as
Landlord may from time to time reasonably request, and (ii) all-risk or fire and
extended coverage insurance upon Tenant's personal property and leasehold
improvements in the


                                       19
<PAGE>

Demised Premises for the full replacement value of such personal property and
leasehold improvements. All liability insurance policies shall name Landlord and
at Landlord's request any mortgagee of all or any portion of the Property as
additional insureds. Tenant shall lodge with Landlord duplicate originals or
certificates of such insurance at or prior to the Commencement Date, together
with evidence of paid-up premiums, and shall lodge with Landlord renewals
thereof at least fifteen (15) days prior to expiration. All such policies or
certificates shall provide that such insurance coverage may not be cancelled or
materially amended unless Landlord and any mortgagee designated by Landlord as
aforesaid are given at least thirty (30) days prior written notice of the same.

            (b) Landlord shall maintain at all times during the Term all-risk
property casualty insurance for the Building in the amount of the replacement
cost thereof, with commercially reasonable deductible amounts.

      20. WAIVER OF SUBROGATION. Each party hereto hereby waives any and every
claim which arises or which may arise in its favor against the other party
hereto during the Term, including any extension or renewal thereof, for any and
all loss of, or damage to, any of its property located within or upon or
constituting a part of the Building, to the extent that such loss or damage is
covered under an insurance policy or policies and to the extent such policy or
policies contain provisions permitting such waivers of claims. Each party agrees
to request its insurers to issue policies containing such provisions and if any
extra premium is payable therefor, the party which would benefit from the
provision shall have the option to pay such additional premium in order to
obtain such benefit.

      21. LIABILITY. (a) Tenant agrees that Landlord, the Property Manager and
their respective officers, employees and agents shall not be liable to Tenant,
and Tenant hereby releases said parties, for any personal injury or damage to or
loss of personal property in the Demised Premises from any cause whatsoever
unless such damage, loss or injury is the result of the negligence or willful
misconduct of Landlord, its Property Manager, or their officers, employees or
agents. Landlord, the Property Manager and their respective officers, employees
and agents shall not be liable to Tenant for any such damage or loss whether or
not the result of their negligence or willful misconduct to the extent Tenant
would be covered by insurance that Tenant is required to carry hereunder. Tenant
shall and does hereby indemnify and hold Landlord harmless of and from all loss
or liability incurred by Landlord (including, without limitation, reasonable
attorney's fees) in connection with any failure of Tenant to fully perform its
obligations under this Lease and in connection with any personal injury or
damage of any type or nature occurring in, or resulting out of Tenant's use of,
the Demised Premises, unless due to the negligence or willful misconduct of
Landlord, its Property Manager, or their officers, employees or agents.

            (b) Landlord shall and does hereby indemnify and hold Tenant
harmless of and from all loss or liability incurred by Tenant (including,
without limitation, reasonable attorney's fees) in connection with any failure
of Landlord to fully perform its obligations under this Lease and in connection
with any personal injury or damage of any type or nature to the extent occurring
in, or resulting out of the negligence or willful misconduct of Landlord, its
Property Manager, or their officers, employees or agents.

      22. ENVIRONMENTAL MATTERS.

            (a) Tenant shall conduct, and cause to be conducted, all operations
and activity at the Demised Premises in compliance with, and shall in all other
respects applicable to the Demised Premises comply with, all applicable present
and future federal, state, municipal and other governmental statutes,
ordinances, regulations, orders, directives and other requirements, and all
present and future requirements of common law, concerning the environment
(hereinafter collectively called "Environmental Statutes") including, without
limitation, (i) those relating to the generation, use, handling, treatment,
storage, transportation, release, emission, disposal, remediation or presence of
any material, substance, liquid, effluent or product, including, without
limitation, hazardous substances, hazardous waste or hazardous materials, (ii)
those concerning conditions at, below or above the surface of the ground and
(iii) those concerning conditions in, at or outside the Building.

            (b) Tenant shall not cause or suffer or permit to occur in, on or
under the Demised Premises any generation, use, manufacturing, refining,
transportation, emission, release, treatment, storage, disposal, presence or
handling of hazardous substances, hazardous wastes or hazardous materials (as
such terms are now or hereafter defined under any Environmental Statute) or any
other material, substance, liquid, effluent or product now or hereafter
regulated by any Environmental Statute (all of the foregoing herein collectively
called "Hazardous Substances"), except that construction materials (other than
asbestos or polychlorinated biphenyls), office equipment, fuel and similar
products (if contained in vehicles) and cleaning solutions, and other
maintenance materials that are or contain Hazardous Substances may be used,
generated, handled or stored on the Demised Premises, provided such is incident
to and reasonably necessary for the operation and maintenance of the Demised
Premises as an office and is in compliance with all Environmental Statutes and
all other applicable governmental requirements. Should Tenant, its agents,
employees or invitees cause any release of Hazardous Substances at the Demised
Premises, Tenant shall immediately contain, remove and dispose of, such
Hazardous Substances and any material that was contaminated by the release and
to remedy and mitigate all threats to human health or the environment relating
to such release. When conducting any such measures the Tenant shall comply with
all Environmental Statutes.

            (c) Tenant hereby agrees to indemnify and to hold harmless Landlord
of, from and against any and all expense, loss or liability suffered by Landlord
by reason of Tenant's breach of any of the provisions of this Section,
including, but not limited to, (i) any and all expenses that Landlord may incur
in complying with any Environmental Statutes, (ii) any and all costs that
Landlord may incur in studying, assessing, containing, removing, remedying,
mitigating, or otherwise responding to, the release of any Hazardous Substance
or waste at or from the Demised Premises, (iii) any and all costs for which
Landlord may be liable to any governmental agency for studying, assessing,
containing, removing, remedying, mitigating, or otherwise responding to, the
release of a Hazardous Substance or waste at or from the Demised Premises, (iv)
any and all fines or penalties assessed, or threatened to be assessed, upon
Landlord by reason of a failure of Tenant to comply with any obligations,
covenants or conditions set forth in this Article, and (v) any and all legal
fees and costs incurred by Landlord in connection with any of the foregoing.

            (d) Tenant's covenants, obligations and liabilities under this
Section shall survive the expiration or earlier termination of this Lease.

      23. SUBORDINATION, NONDISTURBANCE AND ATTORNMENT. This Lease is and shall
be subject and subordinate to all the terms and conditions of all underlying
mortgages and to all ground or underlying leases of the entire Building which
may now or hereafter encumber the Building and/or the Property, and to all
renewals, modifications, consolidations, replacements and extensions thereof,
provided, however, that with respect to future mortgages, this Lease shall be
subject and subordinate so long as the holder of any such mortgage shall have
provided to Tenant a nondisturbance agreement which shall provide, inter alia,
that (a) Tenant's rights under this Lease shall not be extinguished by any
foreclosure or other enforcement proceedings so long as Tenant is not in default
under this Lease (b) subject to the foregoing, the Tenant's rights under this
Lease are subordinate to the rights of the holder of such mortgagee, and (c)
Tenant shall attorn to the holder of such mortgage. Except as provided above,
this clause shall be self-operative and no further instrument of subordination
shall be necessary. Notwithstanding the automatic subordination of this Lease,
Tenant shall execute, within five (5) days after request, any certificate that
Landlord may reasonably require acknowledging such subordination. If Landlord
has attached to this Lease, or subsequently delivers to Tenant, a form of
subordination agreement required by a mortgagee of the Property, Tenant shall
execute and return the same to Landlord within five (5) days after receipt
thereof by Tenant. Notwithstanding the foregoing, the party holding the
instrument to which this Lease is subordinate shall have the right to recognize
and preserve this Lease in the event of any foreclosure sale or possessory
action, and in such case this Lease shall continue in full force and effect at
the option of the party holding the superior lien, and Tenant shall attorn to
such party and shall execute, acknowledge and deliver any instrument that has
for its purpose and effect the confirmation of such attornment. Landlord agrees
to use reasonable efforts to obtain a non-disturbance agreement from the
existing mortgagee of the Property (using such mortgagee's standard form
nondisturbance agreement) for the benefit of Tenant.

      24. ESTOPPEL STATEMENT. Tenant shall from time to time, within ten (10)
days after request by Landlord, execute, acknowledge and deliver to Landlord a
statement certifying that this Lease is unmodified and in full force and effect
(or that the same is in full force and effect as modified, listing any
instruments or modifications), the dates to which rent and other charges have
been paid, and whether or not, to the best of Tenant's knowledge, Landlord is in
default or whether Tenant has any claims or demands against Landlord (and, if
so, the default, claim and/or demand shall be specified), and any other
information reasonably requested by Landlord.

      25. INTENTIONALLY OMITTED.

      26. HOLDING-OVER. Should Tenant continue to occupy the Demised Premises
after the expiration of the Term, including any renewal or renewals thereof, or
after a forfeiture incurred, such tenancy shall (without limitation of any of
Landlord's rights or remedies therefor) be one at sufferance at a minimum
monthly rental equal to one hundred fifty percent (150%) of the rent payable for
the last month of the Term.

      27. SECURITY INTEREST. Landlord shall have and Tenant hereby grants to
Landlord, without warranty of any kind, a continuing security interest for all
rentals and other sums of money becoming due hereunder from Tenant, upon all
goods, wares, equipment, fixtures, furniture and inventory and other personal
property of Tenant situate in the Demised Premises. Notwithstanding the
foregoing, Landlord agrees from time to time to execute and deliver a waiver of
such security interest in favor of any reputable lender providing Tenant with
working business credit, provided such waiver is in form reasonably acceptable
to Landlord.


                                       22
<PAGE>

      28. FINANCIAL STATEMENTS. Upon the request of any mortgagee, prospective
mortgagee or prospective purchaser of the Property, Tenant shall provide to
Landlord complete copies of Tenant's latest annual financial statements and such
other information as may be reasonably requested by such mortgagee and/or
purchaser, provided that such party receiving such information agreement agrees
in writing to keep confidential any such information provided by Tenant.

      29. RENT TAX. If, during the Term, including any renewal or extension
thereof, any tax is imposed upon the privilege of renting or occupying the
Demised Premises or upon the amount of rentals collected therefor, Tenant will
pay each month, as additional rent, a sum equal to such tax or charge that is
imposed for such month, but nothing herein shall be taken to require Tenant to
pay any income, estate, inheritance or franchise tax imposed upon Landlord.

      30. QUIET ENJOYMENT. Tenant, upon paying the rent, and observing and
keeping all covenants, agreements and conditions of this Lease on its part to be
kept, shall quietly have and enjoy the Demised Premises during the term of this
Lease without hindrance or molestation by anyone claiming by or through
Landlord, subject, however, to the exceptions, reservations and conditions of
this Lease.

      31. NOTICES. All notices required to be given by Landlord to Tenant shall
be sufficiently given by overnight express delivery service or by courier
service delivery against written receipt or signed proof of delivery, or mailing
the same by registered or certified mail, return receipt requested, to Tenant's
Notice Address. Notices given by Tenant to Landlord must be given by registered
or certified mail, return receipt requested, overnight express delivery service
or by courier service delivery against written receipt or signed proof of
delivery, to Landlord at Landlord's Notice Address, with a copy to the Property
Manager, and to such other person and address as Landlord may from time to time
designate in writing

      32. MISCELLANEOUS.

            (a) Landlord and Tenant each represents and warrants to the other
that it has dealt with no broker, agent or other intermediary in connection with
this Lease other than Landlord's Broker and Tenant's Broker, described in
Section 13 of the Fundamental Lease Provisions, and that insofar as is known, no
other broker, agent or other intermediary negotiated this Lease or introduced
one party to the other or brought the Building to Tenant's attention for the
lease of space therein. Each of Landlord and Tenant agrees to indemnify, defend
and hold harmless the other and the other's partners, employees, agents, their
officers and partners, from and against any claims made by any broker, agent or
other intermediary other than Landlord's Broker or Tenant's Broker, with respect
to a claim for broker's commission or fee or similar compensation brought by any
person in connection with this Lease and claiming through the indemnifying
party. Landlord agrees to pay all commissions payable to Landlord's Broker
pursuant to a separate agreement between Landlord and Landlord's Broker.
Landlord's Broker shall pay Tenant's Broker a co-brokerage commission pursuant
to a separate agreement between Landlord's Broker and Tenant's Broker.

            (b) The word "Tenant" as used in this Lease shall be construed to
mean tenants in all cases where there is more than one tenant, and the necessary
grammatical changes required to make the provisions hereof apply to
corporations, partnerships or individuals, men or women, shall in all cases be
assumed as though in each case fully expressed. This Lease shall not inure to
the benefit of any assignee, heir, legal representative, transferee or successor
of Tenant except in accordance with the provisions of Section 13 of this


                                       23
<PAGE>

Lease. Subject to the foregoing limitation, each provision hereof shall extend
to and shall, as the case may require, bind and inure to the benefit of Tenant
and its respective heirs, legal representatives, successors and assigns.

            (c) The term "Landlord" as used in this Lease means the fee owner of
the Building or, if different, the party holding and exercising the right, as
against all others (except space tenants of the Building) to possession of the
entire Building. In the event of the voluntary transfer of such ownership or
right to a successor-in-interest of Landlord, Landlord shall be freed and
relieved of all liability and obligation hereunder which shall thereafter accrue
(and, as to any unapplied portion of Tenant's security deposit, Landlord shall
be relieved of all liability therefor upon transfer of such portion to its
successor in interest) and Tenant shall look solely to such successor in
interest for the performance of the covenants and obligations of the Landlord
hereunder (either in terms of ownership or possessory rights) from and after the
date of such transfer. The successor in interest shall not (i) be liable for any
previous act or omission of a prior landlord; (ii) be subject to any rental
offsets or defenses against a prior landlord; or (iii) be liable for any
security not actually received by it. Subject to the foregoing, the provisions
hereof shall be binding upon and inure to the benefit of the successors and
assigns of Landlord.

            (d) Notwithstanding anything to the contrary contained in this
Lease, it is expressly understood and agreed by Tenant that none of Landlord's
covenants, undertakings or agreements are made or intended as personal
covenants, undertakings or agreements by Landlord or its partners, shareholders
or trustees, or any of their respective partners, shareholders or trustees, and
any liability for damage or breach or nonperformance by Landlord, or for
Landlord's negligence, shall be collectible only out of Landlord's interest in
the Building and no personal liability is assumed by, nor at any time may be
asserted against, Landlord or its partners, shareholders or trustees or any of
its or their partners, shareholders, trustees, officers, agents, employees,
legal representatives, successors or assigns, if any; all such liability, if
any, being expressly waived and released by Tenant. Notwithstanding anything to
the contrary contained in this Lease, in no event shall Landlord be liable to
Tenant for any consequential damages, lost profits, loss of business or other
similar damages, regardless of whether the same arises out of the negligence of
Landlord, its agents or employees.

            (e) Landlord and Landlord's agents have made no representation,
agreements, conditions, warranties, understandings, or promises, either oral or
written, other than as herein set forth, with respect to this Lease, the
Building, the Property, the Demised Premises, or otherwise.

            (f) Time is of the essence of this Lease and all of its provisions

            (g) If a party is delayed or prevented from performing any of its
obligations under this Lease by reason of causes beyond its control, the period
of such delay or prevention shall be deemed added to the time herein provided
for the performance of any such obligation by such party, provided, however,
that the foregoing shall not under any circumstances excuse Tenant from the
timely payment of rent hereunder.

            (h) Landlord represents and warrants to Tenant that, to Landlord's
actual knowledge, at the time of delivery of the Demised Premises, the Building
and the Demised Premises shall be in compliance with all applicable municipal,
state and federal laws, rules and regulations, including without limitation the
Americans with Disabilities Act and all applicable building, zoning,
environmental, fire, health and safety codes. Landlord represents that to
Landlord's actual knowledge, neither on the date hereof nor on the Commencement
Date shall


                                       24
<PAGE>

there be any Hazardous Materials within or under the Demised Premises, the
Building or the Property in violation of any Environmental Law.

            (i) Tenant shall not record this Lease or any memorandum thereof.

      33. PRIOR AGREEMENT, AMENDMENTS. This Lease, the exhibits, and any riders
attached hereto and forming a part hereof set forth all of the promises,
agreements, conditions, warranties, representations and understandings between
Landlord and Tenant relative to the Premises and this leasehold. No alteration,
amendment, modification, waiver, understanding or addition to this Lease shall
be binding upon Landlord unless reduced to writing and signed by Landlord or by
a duly authorized agent of Landlord empowered by a written authority signed by
Landlord.

      34. CAPTIONS. The captions of the paragraphs in this Lease are inserted
and included solely for convenience and shall not be considered or given any
effect in construing the provisions hereof.

      35. SEVERABILITY. If any provision contained in this Lease shall, to any
extent, be invalid or unenforceable the remainder of this Lease (and the
application of such provision to the persons or circumstances, if any, other
than those as to which it is invalid or unenforceable) shall not be affected
thereby, and each and every provision of this Lease shall be valid and
enforceable to the fullest extent permitted by law.

      36. GOVERNING LAW. This Lease shall be governed by and construed in
accordance with the laws of the State in which the Property is located.

      37. DELIVERY FOR EXAMINATION. DELIVERY OF THE LEASE TO TENANT SHALL NOT
BIND LANDLORD IN ANY MANNER, AND NO LEASE OR OBLIGATIONS OF LANDLORD SHALL ARISE
UNTIL THIS INSTRUMENT IS SIGNED BY BOTH LANDLORD AND TENANT.
