         13. Restrictive Covenants, Trade Secrets, Etc.

                  (a) For a period of one (1) year after the termination of his
employment with Company, for any reason whatsoever, whether during the term of
this Agreement, upon its expiration or subsequent to its expiration, whether by
Employee or Company, Employee shall not for his own benefit or for the benefit
of any third party, directly or indirectly, in any capacity, participate in any

termination), or potential (engaged in discussion with Company as of the date of
termination) client of Company; or (iii) cause or attempt to cause any current,
former, or potential client to refrain from doing business with Company. In
light of the fact that the clients of Company will be engaged in operations
nationwide and Company will be contacting potential customers for its clients
throughout the entire United States, the restrictions set forth in this
Paragraph 13(a) shall apply throughout the entire United States.

                  (b) During the term of this Agreement and at all times
thereafter, Employee shall not use for his personal benefit, or disclose,
communicate or divulge to, or use for the direct or indirect benefit of any
person, firm, association or company other than Company, any material referred
to in Paragraph 12 above or any information regarding the business methods,
business policies, procedures, techniques, research or development projects or
results, trade secrets, or other knowledge or processes of or developed by
Company or any names and addresses of clients or customers or any data on or
relating to past, present or prospective clients or customers or any other
confidential information relating to or dealing with the business operations or
activities of Company, made known to Employee or learned or acquired by Employee
while in the employ of Company.

                  (c) Any and all writing, inventions, improvements, processes,
procedures and/or techniques which Employee may make, conceive, discover or
develop, either solely or jointly with any other person or persons, at any time
during the term of this Agreement, whether during working hours or at any other
time and whether at the request or upon the suggestion of Company or otherwise,
which relate to or are useful in connection with any business now or hereafter
carried on or contemplated by Company, including developments or expansions of
its present fields of operations, shall be the sole and exclusive property of
Company. Employee shall make full disclosure to Company of all such writings,
inventions, improvements, processes, procedures and techniques, and shall do
everything necessary or desirable to vest the absolute title thereto in Company.
Employee shall write and prepare all specifications and procedures regarding
such inventions, improvements, processes, procedures and techniques and other
aid and assist Company so that Company can prepare and present applications for

<PAGE>

copyright or Letters Patent therefor and can secure such copyright or Letters
Patent wherever possible, as well as reissues, renewals, and extensions thereof,
and can obtain the record title to such copyright or patents so that Company
shall be the sole and absolute owner thereof in all countries in which it may
desire to have copyright or patent protection. Employee shall not be entitled to
any additional or special compensation or reimbursement regarding any and all
such writings, inventions, improvements, processes, procedures and techniques,
except that Company shall reimburse Employee for any expenses which Employee may
incur in vesting absolute title thereto in Company.

                  (d) Employee acknowledges that the restrictions contained in
the foregoing subparagraphs (a), (b), and (c), in view of the nature of the
business in which Company is engaged, are reasonable and necessary in order to
protect the legitimate interests of Company, and that any violation thereof
would result in irreparable injuries to Company, and Employee therefore
acknowledges that, in the event of his violation of any of these restrictions,
Company shall be entitled to obtain from any court of competent jurisdiction
preliminary and permanent injunctive relief as well as damages and an equitable
accounting of all earnings, profits and other benefits arising from such
violation, which rights shall be cumulative and in addition to any other rights
or remedies to which Company may be entitled.

                  (e) Employee agrees that if any or any portion of the
foregoing covenants or the application thereof, is construed to be invalid or
unenforceable, the remainder of such covenant or covenants shall not be affected
and the remaining covenant or covenants shall then be given full force and
effect without regard to the invalid or unenforceable portion(s). If the
covenant is held to be unenforceable because of the area covered, the duration
thereof or the scope thereof, Employee agrees that the court making such
determination shall have the power to reduce the area and/or the duration and/or
scope thereof, and the covenant shall then be enforceable in its reduced form.

                  (f) If Employee violates any of the restrictions contained in
the foregoing subparagraph (a), the restrictive period shall not run in favor of
Employee from the time of the commencement of any violation until such time as
the violation shall be cured by Employee to the satisfaction of Company.

         14. Prior Agreements. Employee represents to Company (a) that there are
no restrictions, agreements or understandings whatsoever to which Employee is a
party which would prevent or make unlawful his execution of this Agreement or
his employment hereunder; (b) there are no agreements, restrictions or
understandings whatsoever to which Employee is a party which place any
limitations as to the companies or individuals with whom he may ado business;
(c) that his execution of this Agreement and his employment hereunder shall not
constitute a breach of any contract, agreement or understanding, oral or
written, to which he is a party and by which he is bound; and (d) that he is
free and able to execute this Agreement and to enter into employment by Company.

         15. Miscellaneous.

                  (a) Waiver. The waiver by Company of a breach of any provision
of this Agreement by Employee shall not operate or be construed as a waiver of
any subsequent breach by Employee. No waiver shall be valid unless in writing
and signed by Company's President.

<PAGE>

                  (b) Controlling Law. This Agreement and all questions relating
to validity, interpretation, performance and enforcement (including, without
limitation, provisions concerning limitations of actions), shall be governed by
and construed in accordance with the laws of the Commonwealth of Pennsylvania,
and without the aid of any canon, custom or rule of law requiring construction
against the draftsman.

                  (c) Notices. All notices, requests, demands and other
communications required or permitted under this Agreement shall be in writing
and shall be deemed to have been duly given, made and received only when
delivered (personally, by courier service such as Federal Express, or by other
messenger) or when deposited in the United States mails, registered or certified
mail, postage prepaid, return receipt requested, addressed in the case of
Company, to its President at its principal place of business, and in case of

binding upon and inure to the benefit of Company and its successors and assigns
and shall be binding upon Employee, his heirs and legal representatives.

                  (e) Execution in Counterparts. This Agreement may be executed
in any number of counterparts, each of which shall be deemed to be an original
as against any party whose signature appears thereon, and all of which shall
together constitute one and the same instrument.

                  (f) Provisions Separable. The provisions of this Agreement are
independent of and separable from each other, and no provision shall be affected
or rendered invalid or unenforceable by virtue of the fact that for any reason
any other or others of them may be invalid or unenforceable in whole or in part.

                  (g) Entire Agreement. This Agreement contains the entire
understanding between the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements and
understandings, inducements or conditions, express or implied, oral or written.
The express terms hereof control and supersede any course of performance an/or
usage of the trade inconsistent with any of the terms hereof. This Agreement may
not be modified or amended other than by an agreement in writing and signed by
the Company's President.

                  (h) Paragraph Headings. The paragraph headings in this
Agreement are for convenience only; they form no part of this Agreement and
shall not affect its interpretation.

                  (i) Survival. The covenants contained in Paragraphs 12 and 13
shall survive the expiration of this Agreement and the termination of Employee's
employment.

                  (j) Number of Days. In computing the number of days for
purposes of this Agreement, all days shall be counted, including Saturdays,
Sundays and holidays; provided, however, that if the final day of any time
period falls on a Saturday, Sunday or holiday on which federal banks are or may
elect to be closed, then the final day shall be deemed to be the next day which
is not a Saturday, Sunday or such holiday.

Fixed Rent, Fixed Rent and Additional Rent payable by Tenant to Landlord under

         2. PREMISES. Landlord does hereby lease, demise and let unto Tenant and
Tenant does hereby hire and lease from Landlord the Premises for the Term, upon
the provisions, conditions and limitations set forth herein.

         3. TERM The Term of this Lease shall commence (the "Commencement Date")
on the date which is the earlier of (i) when Tenant, with Landlord's prior
consent, assumes possession of the Premises, or (ii) upon Substantial Completion
of the Tenant Improvements (as defined in Article 4 below). The Tenant
Improvements (as hereinafter defined) shall be deemed "Substantially Completed"
when they have been completed to the extent that the Premises may be occupied by
Tenant for its Permitted Uses. The Term shall expire on the last day of the
month which is 180 months from the Commencement Date. The Commencement Date
shall be confirmed by Landlord and Tenant by the execution of a Confirmation of
Lease Term in the form attached hereto as Exhibit "B". If Tenant fails to
execute or object to the Confirmation of Lease Term within ten (10) business
days of its delivery, Landlord's determination of such dates shall be deemed
accepted. Notwithstanding the first sentence of this Article 3, in the event
Tenant chooses to construct the Tenant Improvements under Article 4 and the Work
Letter, the Commencement Date shall be the earlier of (i) the date Tenant
assumes occupancy of the Premises for its Permitted Uses or (ii) 165 days
following the Landlord Delivery Date (as defined in the Work Letter).

                                       3

<PAGE>

         4. CONSTRUCTION BY LANDLORD. Landlord shall construct the Building in
accordance with base building specifications to be attached hereto as Exhibit
"E" and the work letter attached hereto as Exhibit "G" ("Work Letter")
(collectively, the "Landlord's Work").

         Landlord shall construct and do such other work to the Premises
(collectively, the "Tenant Improvements") in substantial conformity with the
plans and outline specifications of the plan prepared by Cathers and Associates.
The Tenant Improvements shall be constructed in accordance with the Work Letter.
Landlord shall only be responsible for payment of a maximum cost of $2,856,000
of which $204,000 may be used for moving expenses and $102,000 may be used for
Tenant's architectural services (the "Tenant Allowance"), all such costs in
excess thereof to be borne by Tenant, and shall be paid to Landlord within ten
(10) days of delivery of an invoice and reasonable documentation therefor. If
any material revision or supplement to Tenant Improvements is deemed necessary
by Landlord, those revisions and supplements shall be submitted to Tenant for
approval, which approval shall not be unreasonably withheld or delayed. If
Landlord shall be delayed in such "substantial completion" as a result of (i)
Tenant's failure to furnish plans and specifications within the time frame
stated in the Work Letter; (ii) Tenant's request for materials, finishes or
installations other than Landlord's standard; (iii) Tenant's changes in said
plans; (iv) the performance or completion of any work, labor or services by a
party employed by Tenant; or (v) Tenant's failure to approve final plans,
working drawings or reflective ceiling plans within the time frame stated in the
Work Letter; then the commencement of the Term of this Lease and the payment of
Fixed Rent hereunder shall be accelerated by the number of days of such delay.
If any change, revision or supplement to the scope of the Tenant Improvements is
requested by Tenant or if Tenant fails to provide information or cooperation
required by Landlord in connection with Tenant Improvements within the time
periods required (each, a "Tenant's Delay") then such occurrence shall not
change the Commencement Date of the Term and shall not alter Tenant's
obligations under this Lease. Notwithstanding anything to the contrary stated in
Section 3(a) above, the Term shall commence on the date the Premises would have
been delivered to Tenant but for Tenant's Delay. Tenant shall be solely
responsible for all reasonably documented and invoiced expenses which increase
the costs incurred in connection with a Tenant requested change in the scope of
the Landlord Work (including the finishes set forth therein).

         Landlord will endeavor to Substantially Complete the Tenant
Improvements by February 1, 2002 ("Targeted Date"). In the event the Tenant
Improvements are not Substantially Completed within two months of the Targeted
Date ("Outside Date") for any reason other than Tenant Delay or Force Majeure,
Fixed Rent during the Term shall be abated day for day for each day after the
Outside Date the Premises are not Substantially Completed.

         5. FIXED RENT; SECURITY DEPOSIT.

Tenant shall pay to Landlord without notice or demand, and without set-off, the
annual Fixed Rent payable in the monthly installments of Fixed Rent as set forth
in Section 1(e), in advance on the first business day of each calendar month
during the Term by (i) check sent to Brandywine Realty Service Corporation, P.O.
Box 8538-363, Philadelphia, PA 19171 or (ii) wire transfer of immediately
available funds to the account at First Union National Bank, account no.
2030000359075; such transfer to be confirmed to Brandywine Realty Services
Corporation accounting department (610/325-5622 - fax) by written facsimile with
ABA routing number 031000503. Fixed Rent shall not commence nor be due and owing
until the Commencement Date. Notwithstanding the immediately preceding sentence,
the first full month's installment and the Security Deposit shall be paid upon
the execution of this Lease.

                                       4
<PAGE>

            (a) In the event any Fixed Rent or Additional Rent, charge, fee or
other amount due from Tenant under the terms of this Lease are not paid to
Landlord when due, Tenant shall also pay as Additional Rent a service and
handling charge equal to five (5%) percent of the total payment then due. The
aforesaid late fee shall begin to accrue on the first day following a payment
due date, irrespective of any cure period granted hereunder. This provision
shall not prevent Landlord from exercising any other remedy herein provided or
otherwise available at law or in equity in the event of any default by Tenant.

            (b) Tenant shall be required to pay a Security Deposit of $100,000
under this Lease (the "Collateral"), as security for the prompt, full and
faithful performance by Tenant of each and every provision of this Lease and of
all obligations of Tenant hereunder. Upon execution hereof, Tenant shall pay the
Security Deposit to Landlord in the form of (i) cash to be held in a
non-interest bearing account or (ii) an irrevocable letter of credit in the
amount of $100,000 in substantially the form attached hereto as Exhibit "F". The
letter of credit shall name Landlord as the beneficiary thereof and shall be
issued by a bank approved by Landlord.

            (c) No interest shall be paid to Tenant on the Collateral, and
Landlord shall have the right to commingle the Collateral with other Security
Deposits held by Landlord. If Tenant fails to perform any of its obligations
hereunder, Landlord may use, apply or retain the whole or any part of the
Collateral for the payment of (i) any rent or other sums of money which Tenant
may not have paid when due, (ii) any sum expended by Landlord on Tenant's behalf
in accordance with the provisions of this Lease, and/or (iii) any sum which
Landlord may expend or be required to expend by reason of Tenant's default,
including, without limitation, any damage or deficiency in or from the reletting
of the Premises as provided in this Lease. The use, application or retention of
the Collateral, or any portion thereof, by Landlord shall not prevent Landlord
from exercising any other right or remedy provided by this Lease or by law (it
being intended that Landlord shall not first be required to proceed against the
Collateral) and shall not operate as either liquidated damages or as a
limitation on any recovery to which Landlord may otherwise be entitled. If any
portion of the Collateral is used, applied or retained by Landlord for the
purposes set forth above, Tenant agrees, within ten (10) days after the written
demand therefor is made by Landlord, to deposit cash or a new letter of credit
with the Landlord in an amount sufficient to restore the Collateral to its
original amount. In addition to the foregoing, if Tenant defaults more than
twice in its performance of a monetary obligation under this Lease, irrespective
of whether such default is cured, Landlord may require Tenant to increase the
Collateral to the greater of twice the (i) Fixed Rent paid monthly, or (ii) the
initial amount of the Collateral.

            (d) If Tenant shall fully and faithfully comply with all of the
provisions of this Lease, the Collateral, or any balance thereof, shall be
returned to Tenant without interest after the expiration of the Term or upon any
later date after which Tenant has vacated the Premises. In the absence of
evidence satisfactory to Landlord of any permitted assignment of the right to
receive the Collateral, Landlord may return the same to the original Tenant,
regardless of one or more assignments of Tenant's interest in this Lease or the
Collateral. Upon the return of the Collateral, or the remaining balance thereof,
to the original Tenant or any successor to the original Tenant, Landlord shall
be completely relieved of liability with respect to the Collateral.

                                       5
<PAGE>

            (e) In the event of a transfer of the Project or the Building,
Landlord shall transfer the Collateral to the vendee or lessee and Landlord
shall thereupon be released by Tenant from all liability for the return of such
Collateral. Upon the assumption of such Collateral by the transferee, Tenant
agrees to look solely to the new landlord for the return of said Collateral, and
the provisions hereof apply to every transfer or assignment made of the
Collateral to a new landlord. Tenant further covenants that it will not assign
or encumber or attempt to assign or encumber the Collateral and that neither
Landlord nor its successors or assigns shall be bound by any such assignment,
encumbrance, attempted assignment or attempted encumbrance. The Collateral shall
not be mortgaged, assigned or encumbered in any manner whatsoever by Tenant
without the prior written consent of Landlord.

         6. ADDITIONAL RENT.

            (a) Commencing on the Commencement Date, and in each calendar year
thereafter during the Term (as same may be extended), Tenant shall pay to
Landlord, Tenant's Allocated Share of the following charges ("Recognized
Expenses"), without deduction or set off except as otherwise specifically set
forth herein, to the extent such Recognized Expenses exceed Base Amount of
$5.50/s.f.

                  (1) Insurance Premiums. All reasonable premiums paid or
payable by Landlord for insurance with respect to the Project as follows: (a)
fire and extended coverage insurance (including demolition and debris removal);
(b) insurance against Landlord's rental loss or abatement (but not including
business interruption coverage on behalf of Tenant), from damage or destruction
from fire or other casualty; (c) Landlord's comprehensive liability insurance
(including bodily injury and property damage) and boiler insurance; and (d) such
other insurance as Landlord or any reputable mortgage lending institution
holding a mortgage on the Premises may require ("Insurance Premiums").

If the coverage period of any of such insurance obtained by Landlord commences
before or extends beyond the Term or if such insurance is provided under a
blanket policy, the premium therefore shall be prorated to the Term. If any such
insurance is provided by blanket coverage, the part of the premium allocated to
the Project shall be equitably determined by Landlord but shall not exceed the
amount of premium due if insurance was provided by a policy only insuring the
Project. Should Tenant's occupancy or use of the Premises at any time change and
thereby cause an increase in such insurance premiums on the Premises, Building
and/or Project, Tenant shall pay to Landlord the entire amount of such
reasonably documented increase, however, Tenant shall not be responsible for
increases of insurance premiums on the Premises, Building and/or Project caused
by other tenants in the Building.

                  (2) Operating Expenses. All costs and expenses related to the
Project incurred by Landlord, including, but not limited to:

                                       6

<PAGE>

            (a) All costs and expenses, without taking into account discounts or
rebates, related to the operation of the Building and Project, including, but
not limited to, lighting, cleaning the Building exterior and common areas of the
Building interior, trash removal and recycling, repairs and maintenance of the
roof and storm water management system, on-going maintenance of fire suppression
and alarm systems, utilities benefiting the common areas ("Utilities"), removing
snow, ice and debris and maintaining all landscape areas, (including replacing
and replanting flowers, shrubbery and trees), maintaining and repairing all
other exterior improvements on the Project, all repairs and compliance costs
necessitated by laws enacted or which become effective after the date hereof
(including, without limitation, any additional regulations or requirements
enacted after the date hereof regarding the Americans With Disabilities Act (as
such applies to the Project or common areas but not to any individual tenant's
space), if applicable) required of Landlord under applicable laws, rules and
regulations and policing and regulating traffic to and from the Project.

            (b) All costs and expenses incurred by Landlord for environmental
testing, sampling or monitoring required by statute, regulation or order of
governmental authority, except to the extent the foregoing is necessitated by
the spilling or depositing of any hazardous substance on the Project by Landlord
or any tenant of the Building.

            (c) Any other expense or charge (including reasonably allocated
general and administrative charges) which would typically be considered an
expense of maintaining, operating or repairing the Project under generally
accepted accounting principles.

            (d) Management fee not to exceed five (5%) percent of Fixed Rent
which is applicable to the overall operation of the Project. It is expressly
understood that legal fees incurred in an action against an individual tenant
shall not be deemed includable as an operating expense pursuant to this
provision.

            (e) Capital expenditures and capital repairs and replacements shall
be included as operating expenses solely to the extent of the amortized costs of
same over the useful life of the improvement in accordance with generally
accepted accounting principles.

         Notwithstanding the foregoing, the term "Recognized Expenses" shall not
include any of the following:

            (a) Repairs or other work occasioned by fire, windstorm or other
insured casualty or by the exercise of the right of eminent domain;

            (b) Leasing commissions, accountants', consultants', auditors or
attorneys' fees, costs and disbursements and other expenses incurred in
connection with negotiations or disputes with other tenants or prospective
tenants or other occupants, or associated with the enforcement of any other
leases or the defense of Landlord's title to or interest in the real property or
any part thereof;

                                       7

<PAGE>

            (c) Costs incurred by Landlord in connection with construction of
the Building and related facilities, the correction of latent defects in
construction of the Building or the discharge of Tenant Improvements;

            (d) Costs (including permit, licenses and inspection fees) incurred
in renovating or otherwise improving or decorating, painting, or redecorating
the Building or space for other tenants or other occupants or vacant space;

            (e) Costs of any items or services sold or provided to tenants
(including Tenant) for which Landlord is reimbursed by such tenants;

            (f) Depreciation and amortization;

            (g) Costs incurred due to a breach by Landlord or any other tenant
of the terms and conditions of any lease;

            (h) The cost for supplies, utilities or other materials, to the
extent that the costs of such services, supplies, utilities or materials exceed
the reasonable costs that would have been paid had the services, supplies or
materials been provided by unaffiliated parties on a reasonable basis without
taking into effect volume discounts or rebates offered to Landlord as a
portfolio purchaser;

            (i) Interest on debt or amortization payments on any mortgage or
deeds of trust or any other borrowings and any ground rent;

            (j) Ground rents or rentals payable by Landlord pursuant to any
over-lease;

            (k) Any compensation paid to clerks, attendants or other persons in
commercial concessions operated by Landlord;

            (l) Costs incurred in managing or operating any "pay for" parking
facilities within the Project;

            (m) Expenses resulting from the negligence or willful misconduct of
Landlord;

            (n) Any fines or fees for Landlord's failure to comply with
governmental, quasi-governmental, or regulatory agencies' rules and regulations;
and

            (o) Legal, accounting and other expenses related to Landlord's
financing, re-financing, mortgaging or selling the Building or the Project.

                  (3) Taxes. Taxes shall be defined as all taxes, assessments
and other governmental charges ("Taxes"), including special assessments for
public improvements or traffic districts which are levied or assessed against
the Project during the Term to the extent such Taxes are properly allocable to
the Term or, if levied or assessed prior to the Term, which properly are

                                       8

<PAGE>

allocable to the Term, and real estate tax appeal expenditures incurred by
Landlord to the extent of any reduction resulting thereby. Nothing herein
contained shall be construed to include as Taxes: (A) any inheritance, estate,
succession, transfer, gift, franchise, corporation, net income or profit tax or
capital levy that is or may be imposed upon Landlord or (B) any transfer tax or
recording charge resulting from a transfer of the Building or the Project;
provided, however, that if at any time during the Term the method of taxation
prevailing at the commencement of the Term shall be altered so that in lieu of
or as a substitute for the whole or any part of the taxes now levied, assessed
or imposed on real estate as such there shall be levied, assessed or imposed (i)
a tax on the rents received from such real estate, or (ii) a license fee
measured by the rents receivable by Landlord from the Premises or any portion
thereof, or (iii) a tax or license fee imposed upon Premises or any portion
thereof, then the same shall be included in the computation of Taxes hereunder.

                  (b) Tenant shall pay, in monthly installments in advance, on
account of Tenant's Allocated Share of Recognized Expenses and Taxes, the
estimated amount of the increase of such Recognized Expenses and Taxes for such
year in excess of the Base Amount as determined by Landlord in its reasonable
discretion and as set forth in a notice to Tenant, such notice to include the
basis for such calculation. Prior to the end of the calendar year in which the
Lease commences and thereafter for each successive calendar year (each, a "Lease
Year"), or part thereof, Landlord shall send to Tenant a statement of projected
increases in Recognized Expenses and Taxes in excess of the Base Amount and
shall indicate what Tenant's projected share of Recognized Expenses and Taxes
shall be. Said amount shall be paid in equal monthly installments in advance by
Tenant as Additional Rent commencing January 1 of the applicable Lease Year.

                  (c) If during the course of any Lease Year, Landlord shall
have reason to believe that the Recognized Expenses and Taxes shall be different
than that upon which the aforesaid projections were originally based, then
Landlord, one time in any calendar year, shall be entitled to adjust the amount
by reallocating the remaining payments for such year, for the months of the
Lease Year which remain for the revised projections, and to advise Tenant of an
adjustment in future monthly amounts to the end result that the Recognized
Expenses and Taxes shall be collected on a reasonably current basis each Lease
Year.

                  (d)      Intentionally omitted.

                  (e) By April 30th of each Lease Year or as soon thereafter as
administratively available, Landlord shall send to Tenant a reasonably detailed
statement of actual expenses incurred for Recognized Expenses and Taxes
("Recognized Expenses Statement") for the prior Lease Year showing the Allocated
Share due from Tenant. Landlord shall use its reasonable efforts to provide
Tenant with the aforesaid statements on or before April 30 of each Lease Year;
provided, if Landlord does not furnish Tenant with an Recognized Expenses
Statement for any calendar year during the Term, within twenty-four (24) months
of the end of each calendar year and within twelve (12) months from the date of
expiration or earlier termination of this Lease, then (a) Landlord shall no
longer have the right to deliver an Recognized Expenses Statement for such
calendar year for the purpose of collecting a deficiency for said calendar year,
(b) Landlord shall still be obligated to deliver an Recognized Expenses

                                       9

<PAGE>

Statement for such calendar year if there is an overpayment by Tenant for such
calendar year. In the event the amount prepaid by Tenant exceeds the amount that
was actually due then Landlord shall issue a credit to Tenant in an amount equal
to the over charge, which credit Tenant may apply to future payments on account
of Recognized Expenses and Taxes until Tenant has been fully credited with the
over charge. If the credit due to Tenant is more than the aggregate total of
future payments on account of Recognized Expenses and Taxes, Landlord shall pay
to Tenant the difference between the credit in such aggregate total. In the
event Landlord has undercharged Tenant, then Landlord shall send Tenant an
invoice with the additional amount due, which amount shall be paid in full by
Tenant within thirty (30) days of receipt. In the event Landlord is refunded
Taxes during the Term, Landlord shall pass that refund to Tenant, and this
obligation shall survive the expiration or earlier termination of the Lease.

                  (f) Each of the Recognized Expenses and Tax amounts, whether
requiring lump sum payment or constituting projected monthly amounts added to
the Fixed Rent, shall for all purposes be treated and considered as Additional
Rent and the failure of Tenant to pay the same as and when due in advance and
without demand shall have the same effect as failure to pay any installment of
the Fixed Rent and shall afford Landlord all the remedies in the Lease therefor
as well as at law or in equity.

                  (g) If this Lease terminates other than at the end of a
calendar year, Landlord's annual estimate of Recognized Expenses and Taxes shall
be accepted by the parties as the actual Recognized Expenses and Taxes for the
year until Landlord provides Tenant with an actual statement in accordance with
subsection 6(d) above.

                  (h) Tenant shall have the right, at its sole cost and expense,
to audit or have its appointed accountant audit Landlord's records related to
Recognized Expenses within 120 days of the date Tenant receives a Recognized
Expenses Statement provided that any such audit may not occur more frequently
than once each calendar year nor apply to any year prior to the year to which
the most recently received Recognized Expenses Statement pertains. In the event
Tenant's audit discloses any discrepancy, Landlord and Tenant shall use their
best efforts to resolve the dispute and make an appropriate adjustment, failing
which, they shall submit any such dispute to arbitration pursuant to the rules
and under the jurisdiction of the American Arbitration Association in
Philadelphia, Pennsylvania. The decision rendered in such arbitration shall be
final, binding and non-appealable. The expenses of arbitration, other than
individual legal and accounting expenses which shall be the respective parties'
responsibility, shall be divided equally between the parties. In the event, by
agreement or as a result of an arbitration decision, it is determined that the
actual Recognized Expenses were more or less than those claimed by the Landlord
by more than ten percent (10%), then the actual, reasonable hourly costs to
Tenant of Tenant's audit (including legal and accounting costs) shall be
reimbursed by Landlord. Tenant agrees not to utilize a contingent fee auditor.
In the event it is determined by arbitration that the actual Recognized Expenses
exceeded those claimed by the Landlord by more or less than ten percent (10%),
due to the negligence or willful misconduct of Landlord, then Tenant shall be
entitled to recover its actual and reasonable damages caused by such negligence
or intentional misconduct.

         7. ELECTRICITY CHARGES. Tenant shall make arrangements with the
electric utility company to provide, in Tenant's name electricity necessary for
Tenant's use of the Premises, and Tenant shall cause such utility to be
separately metered, to the extent possible. Tenant shall pay directly to the
company furnishing utility service the cost of all service connection fees and
the cost of all utilities consumed throughout the Term. In the event that Tenant
fails to pay in a timely manner any sum required under this Section, Landlord
shall have the right, but not the obligation, to pay any such sum. Any sum so
paid by Landlord shall be deemed to be owing by Tenant to Landlord and due and
payable as Additional Rent within five (5) days after demand therefor. Tenant's
obligations for the payment of the costs incurred for utilities that serve the
Premises prior to the termination of this Lease shall survive termination
hereof.

         8. SIGNS; USE OF PREMISES AND COMMON AREAS.

            (a) Landlord shall provide Tenant with standard identification
signage on all Building directories. Subject to applicable municipal and
township requirements and approvals, and Landlord's prior approval as to type,
size, location, design, lighting, air structural and aesthetic features, Tenant
shall have the right to (i) be included on the ground mounted complex signage
along Lindenhurst Road and (ii) request that Landlord install facade signs on
the Building, with such facade signs to bear the name of the Tenant and the cost
of all signage to be borne by Tenant or paid out of the Tenant Allowance . No
other signs shall be placed, erected or maintained by Tenant at any place upon
the Premises, Building or Project.

            (b) Tenant may use and occupy the Premises only for the express and
limited purposes stated in Article 1(j) above; and the Premises shall not be
used or occupied, in whole or in part, for any other purpose without the prior
written consent of Landlord; provided that Tenant's right to so use and occupy
the Premises shall remain expressly subject to the provisions of "Governmental
Regulations", Article 28 herein. Subject to the last paragraph of Section 10
below, no machinery or equipment shall be permitted that shall cause vibration,
noise or disturbance beyond the Premises.

            (c) Tenant shall not overload any floor or part thereof in the
Premises or the Building, including any public corridors or elevators therein,
bringing in, placing, storing, installing or removing any large or heavy
articles, and Landlord may prohibit, or may direct and control the location and
size of, safes and all other heavy articles, and may require, at Tenant's sole
cost and expense, supplementary supports of such material and dimensions as
Landlord may deem necessary to properly distribute the weight.

            (d) Tenant shall not install in or for the Premises, without
Landlord's prior written approval, which approval shall not be unreasonably
withheld, any equipment which requires more electric current than Landlord is
required to provide under this Lease, and Tenant shall ascertain from Landlord
the maximum amount of load or demand for or use of electrical current which can
safely be permitted in and for the Premises, taking into account the capacity of
electric wiring in the Building and the Premises and the needs of Building
common areas (interior and exterior) and the requirements of other tenants of
the Building, Tenant and shall not in any event connect a greater load than such
safe capacity. The electrical capacity of the Building is set forth on Exhibit
"E" attached hereto and made a part hereof.

                                       11
<PAGE>

            (e) Tenant shall not commit or suffer any waste upon the Premises,
Building or Project or any nuisance, or do any other act or thing which may
disturb the quiet enjoyment of any other tenant in the Building or Project.

            (f) Tenant shall have the right, non-exclusive and in common with
others, to use the exterior paved driveways and walkways of the Building for
vehicular and pedestrian access to the Building and all other interior common
areas. Provided Tenant is the only tenant in the Building, Tenant shall also
have the exclusive right to use the designated parking areas of the Project for
the parking of automobiles of Tenant and its employees and business visitors,
incident to Tenant's permitted use of the Premises; provided that if Tenant is
not the only tenant in the Building, Landlord shall have the right to restrict
or limit Tenant's utilization of the parking areas in the event the same become
overburdened and in such case to equitably allocate on proportionate basis or
assign parking spaces among Tenant and the other tenants of the Building.
Landlord shall have the right to establish reasonable regulations, applicable to
all tenants, governing the use of or access to any interior or exterior common
areas; and such regulations, when communicated by written notification from
Landlord to Tenant, shall be deemed incorporated by reference hereinafter and
part of this Lease. Notwithstanding the foregoing, Landlord shall provide Tenant
with five (5) reserved parking places.

         9. ENVIRONMENTAL MATTERS.

            (a) Hazardous Substances.

                  (i) Tenant shall not, except as provided in subparagraph (ii)
below, bring or otherwise cause to be brought or permit any of its agents,
employees, contractors or invitees to bring in, on or about any part of the
Premises, Building or Project, any hazardous substance or hazardous waste in
violation of law, as such terms are or may be defined in (x) the Comprehensive
Environmental Response, Compensation and Liability Act, 42 U.S.C. 9601 et seq.,
as the same may from time to time be amended, and the regulations promulgated
pursuant thereto ("CERCLA"); the United States Department of Transportation
Hazardous Materials Table (49 CFR 172.102); by the Environmental Protection
Agency as hazardous substances (40 CFR Part 302); the Clean Air Act; and the
Clean Water Act, and all amendments, modifications or supplements thereto;
and/or (y) any other rule, regulation, ordinance, statute or requirements of any
governmental or administrative agency regarding the environment (collectively,
(x) and (y) shall be referred to as an "Applicable Environmental Law").

                  (ii) Tenant may bring to and use at the Premises, hazardous
substances incidental to its normal business operations under the NAI Code
referenced in paragraph 1(m) above in de minimis quantities and in accordance
with all Applicable Environmental Law. Tenant shall store and handle such
substances in strict accordance with all Applicable Environmental Law.

                                       12

<PAGE>

            (b) NAI Numbers.

                  (i) Tenant represents and warrants that Tenant's NAI number as
designated in the North American Industry Classification System Manual prepared
by the Office of Management and Budget, and as set forth in Article 1(m) hereof,
is correct. Tenant represents that the specific activities intended to be
carried on in the Premises are in accordance with Article 1(j).

                  (ii) Tenant shall not engage in operations at the Premises
which involve the generation, manufacture, refining, transportation, treatment,
storage, handling or disposal of "hazardous substances" or "hazardous waste" as
such terms are defined under any Applicable Environmental Law. Tenant further
covenants that it will not cause or permit to exist any "discharge" (as such
term is defined under Applicable Environmental Laws) on or about the Premises.

                  (iii) In addition, upon written request of Landlord, Tenant
shall cooperate with Landlord in obtaining Applicable Environmental Laws
approval of any transfer of the Building. Specifically in that regard, Tenant
agrees that it shall (1) execute and deliver all affidavits, reports, responses
to questions, applications or other filings required by Landlord and related to
Tenant's activities at the Premises, (2) allow inspections and testing of the
Premises during normal business hours, and (3) as respects the Premises, perform
any requirement reasonably requested by Landlord necessary for the receipt of
approvals under Applicable Environmental Law, provided the foregoing shall be at
no out-of-pocket cost or expense to Tenant except for clean-up and remediation
costs arising from Tenant's violation of this Article 9.

            (c) Additional Terms. In the event of Tenant's failure to comply in
full with this Article, Landlord may, after written notice to Tenant and
Tenant's failure to cure within thirty (30) days of its receipt of such notice,
at Landlord's option, perform any and all of Tenant's obligations as aforesaid
and all reasonable costs and expenses incurred by Landlord in the exercise of
this right shall be deemed to be Additional Rent payable on demand and with
interest at the Default Rate. The parties acknowledge and agree that Tenant
shall not be held responsible for any environmental issue at the Premises unless
such issue was caused by an action or omission of Tenant or its agents,
employees, consultants or invitees. This Article 9 shall survive the expiration
or sooner termination of this Lease for five (5) years. In the event that no
such claim shall have been brought within such time frame, Tenant shall be
released of any and all such liability.

            (d) Landlord Warranty. To the best of Landlord's actual knowledge,
Landlord warrants that the Premises and Project are free and clear of any
Hazardous Materials from Landlord's operation or any prior tenant's operation
and that Landlord will indemnify Tenant from any and all contamination of the
Project caused by Landlord or its agents, employees or invitees.

         10. TENANT'S ALTERATIONS. Tenant will not cut or drill into or secure
any fixture, apparatus or equipment or make alterations, improvements or
physical additions (collectively, "Alterations") of any kind to any part of the
Premises without first obtaining the written consent of Landlord, such consent
not to be unreasonably withheld. Alterations shall be with Landlord's consent,
which shall not be unreasonably withheld and be performed by Tenant, at its sole
cost and expense. Landlord's consent shall not be required for the installation
of any office equipment or fixtures including internal partitions which do not

                                       13

<PAGE>

require disturbance of any structural elements or systems (other than attachment
thereto) within the Building. Moreover, Landlord's consent shall not be required
where (1) the improvement involved cost less than $50,000 each or an aggregate
of $200,000 per year and (2) the same shall not affect the Building structure or
systems or in any manner diminish or impair the value of the Building as a
modern, first class suburban office building. If Landlord approves Tenant's
Alterations or if no approval is required, Tenant, prior to the commencement of
labor or supply of any materials, must furnish to Landlord (i) a duplicate or
original policy or certificates of insurance evidencing (a) general public
liability insurance for personal injury and property damage in the minimum
amount of $1,000,000.00 combined single limit, (b) statutory workman's
compensation insurance, and (c) employer's liability insurance from each
contractor to be employed (all such policies shall be non-cancelable without
thirty (30) days prior written notice to Landlord and shall be in amounts and
with companies satisfactory to Landlord); (ii) construction documents prepared
and sealed by a registered Pennsylvania architect if such alteration is in
excess of $25,000; (iii) all applicable building permits required by law; and
(iv) an executed, effective Waiver of Mechanics Liens from such contractors and
all sub-contractors. Any consent by Landlord permitting Tenant to do any or
cause any work to be done in or about the Premises shall be and hereby is
conditioned upon Tenant's work being performed by workmen and mechanics working
in harmony and not interfering with labor employed by Landlord, Landlord's
mechanics or their contractors or by any other tenant or their contractors. If
at any time any of the workmen or mechanics performing any of Tenant's work
shall be unable to work in harmony or shall interfere with any labor employed by
Landlord, other tenants or their respective mechanics and contractors, then the
permission granted by Landlord to Tenant permitting Tenant to do or cause any
work to be done in or about the Premises, may be withdrawn by Landlord upon
forty-eight (48) hours written notice to Tenant.

                  All Alterations (whether temporary or permanent in character)
made in or upon the Premises (other than the Landlord Work which will remain on
the Premises), either by Landlord or Tenant, shall be Landlord's property upon
installation and shall remain on the Premises without compensation to Tenant
unless Landlord provides written notice to Tenant to remove same at the
expiration of the Lease, in which event Tenant shall promptly remove such
Alterations and restore the Premises to good order and condition. All furniture,
movable trade fixtures and equipment (including telephone and communication
equipment system wiring and cabling) installed by Tenant, its assignees and
sublessees) shall be removed by Tenant at the termination of this Lease. All
such installations, removals and restoration shall be accomplished in a good and
workmanlike manner so as not to damage the Premises or Building and in such
manner so as not to disturb other tenants in the Building. If Tenant fails to
remove any items required to be removed pursuant to this Article, Landlord may
do so and the reasonable costs and expenses thereof shall be deemed Additional
Rent hereunder and shall be reimbursed by Tenant to Landlord within fifteen (15)
business days of Tenant's receipt of an invoice therefor from Landlord.

                                       14

<PAGE>

         11. CONSTRUCTION LIENS.

            (a) Tenant will not suffer or permit any contractor's,
subcontractor's or supplier's lien (a "Construction Lien") to be filed against
the Premises or any part thereof by reason of work, labor services or materials
supplied or claimed to have been supplied to Tenant; and if any Construction
Lien shall at any time be filed against the Premises or any part thereof,
Tenant, within thirty (30) days after notice of the filing thereof, shall cause
it to be discharged of record by payment, deposit, bond, order of a court of
competent jurisdiction or otherwise. If Tenant shall fail to cause such
Construction Lien to be discharged within the period aforesaid, then in addition
to any other right or remedy, Landlord may, but shall not be obligated to,
discharge it either by paying the amount claimed to be due or by procuring the
discharge of such lien by deposit or by bonding proceedings. Any amount so paid
by Landlord, plus all of Landlord's costs and expenses associated therewith
(including, without limitation, reasonable legal fees), shall constitute
Additional Rent payable by Tenant under this Lease and shall be paid by Tenant
to Landlord on demand with interest from the date of advance by Landlord at the
Default Rate.

            (b) Nothing in this Lease, or in any consent to the making of
alterations or improvements shall be deemed or construed in any way as
constituting authorization by Landlord for the making of any alterations or
additions by Tenant within the meaning of 49 P.S. Sections 1101-1902, as
amended, or under the Contractor and Subcontractor Payment Act or any amendment
thereof, or constituting a request by Landlord, express or implied, to any
contractor, subcontractor or supplier for the performance of any labor or the
furnishing of any materials for the use or benefit of Landlord.

         12. ASSIGNMENT AND SUBLETTING.

            (a) Subject to the remaining subsections of Article 12, except as
expressly permitted pursuant to this section, Tenant shall not, without the
prior written consent of Landlord, such consent not to be unreasonably withheld,
conditioned or delayed, assign, transfer, mortgage or hypothecate this Lease or
any interest herein or sublet the Premises or any part thereof. Any of the
foregoing acts without such consent shall be void. Subject to subparagraph 12(i)
below, this Lease shall not, nor shall any interest herein, be assignable as to
the interest of Tenant by operation of law or by merger, consolidation or asset
sale, without the written consent of Landlord.

            (b) If, at any time Tenant desires to (1) assign this Lease or (2)
sublet more than twenty percent (20%) of the Premises (20,000 square feet) or
(3) sublet for a term which would end during the last Lease Year, then Tenant
shall give notice to Landlord of (i) Tenant's desire to sublet or assign and in
the case of subletting (ii) the square footage proposed to be sublet and
Landlord shall have thirty (30) days (the "Notice Period") after Landlord's
receipt of such notice to give Tenant written notice of its election to
recapture that portion of the Premises as is proposed by Tenant to be sublet
(and in each case, the designated and non-designated parking spaces included in
this demise, or a pro-rata portion thereof in the instance of the recapture of
less than all of the Premises), and terminate this Lease with respect to the

                                       15

<PAGE>

space being recaptured. If Landlord shall not exercise the foregoing right of
recapture within said Notice Period, Landlord shall be deemed to have waived its
right to recapture such space. Within 120 days of the expiration of said Notice
Period, or, in the event Landlord does not have the right to recapture then
within a reasonable time of finding a proposed subtenant or assignee, Tenant
shall provide Landlord the following information regarding the proposed
subtenant or assignee: the name, address and contact party for the proposed
assignee or subtenant, a description of such party's business history, the
effective date of the proposed assignment or sublease (including the proposed
occupancy date by the proposed assignee or sublessee), a floor plan
professionally drawn to scale, depicting the proposed sublease area, and a
statement of the duration of the proposed sublease (which shall in any and all
events expire by its terms prior to the scheduled expiration of this Lease, and
immediately upon the sooner termination hereof) and any other information
Landlord may reasonably request with respect to such proposed subtenant or
assignee. Landlord shall respond to Tenant's request for consent to said
subletting or assignment within ten (10) business days of the date Landlord is
in receipt of all of the foregoing information. In the event Landlord fails to
respond with said time frame, Landlord's consent shall be deemed withheld to
such sublet or assignment. Landlord shall not have a right to recapture if
Tenant proposes to sublet less than twenty percent (20%) of the Premises or
proposes to sublet for a term which would end prior to the last Lease Year.

            (c) If Landlord elects to recapture the Premises or a portion
thereof as aforesaid, then from and after the effective date thereof as approved
by Landlord, after Tenant shall have fully performed such obligations as are
enumerated herein to be performed by Tenant in connection with such recapture,
and except as to obligations and liabilities accrued and unperformed (and any
other obligations expressly stated in this Lease to survive the expiration or
sooner termination of this Lease), Tenant shall be released of and from all
lease obligations thereafter otherwise accruing with respect to the Premises (or
such lesser portion as shall have been recaptured by Landlord). The Premises, or
such portion thereof as Landlord shall have elected to recapture, shall be
delivered by Tenant to Landlord free and clear of all furniture, furnishings,
personal property and removable fixtures, with Tenant repairing and restoring
any and all damage to the Premises resulting from the installation, handling or
removal thereof, and otherwise in the same condition as Tenant is, by the terms
of this Lease, required to redeliver the Premises to Landlord upon the
expiration or sooner termination of this Lease, reasonable wear and tear and
damage by casualty excepted. In the event of a sublease of less than all of the
Premises, the cost of erecting any required demising walls, entrances and
entrance corridors, and any other or further improvements required in connection
therewith, including without limitation, modifications to HVAC, electrical,
plumbing, fire, life safety and security systems (if any), painting,
wallpapering and other finish items as may be acceptable to or specified by
Landlord, all of which improvements shall be made in accordance with applicable
legal requirements and Landlord's then-standard base building specifications,
shall be performed by Landlord's contractors, and shall be shared 50% by Tenant
and 50% by Landlord. Upon the completion of any recapture and termination as
provided herein, Tenant's Fixed Rent, Recognized Expenses and other monetary
obligations hereunder shall be adjusted pro-rated based upon the reduced
rentable square footage then comprising the Premises.

                                       16
<PAGE>

            (d) If Landlord provides written notification to Tenant electing not
to recapture the Premises (or so much thereof as Tenant had proposed to
sublease), or if Landlord does not have the right to recapture, then Tenant may
proceed to market the designated space and may complete such transaction and
execute an assignment of this Lease or a sublease agreement (in each case in
form reasonably acceptable to Landlord) within a period of five (5) months next
following Landlord's notice to Tenant that it declines to recapture such space,
provided that Tenant shall have first obtained in any such case the prior
written consent of Landlord to such transaction, which consent shall not be
unreasonably withheld. If, however, Tenant shall not have assigned this Lease or
sublet the Premises with Landlord's prior written consent as aforesaid within
five (5) months next following Landlord's notice to Tenant that Landlord
declines to recapture the Premises (or such portion thereof as Tenant initially
sought to sublease), then in such event, Tenant shall again be required to
request Landlord's consent to the proposed transaction, whereupon Landlord's
right to recapture the Premises (or such portion as Tenant shall desire to
sublease) shall be renewed upon the same terms and as otherwise provided in
subsection (b) above.

            For purposes of this Section 12(d), and without limiting the basis
upon which Landlord may withhold its consent to any proposed assignment or
sublease, the parties agree that it shall not be unreasonable for Landlord to
withhold its consent to such assignment or sublease if: (i) in Landlord's
reasonable opinion, the proposed assignee or sublessee shall have no reliable
credit history or an unfavorable credit history, or other reasonable evidence
exists that the proposed assignee or sublessee will experience difficulty in
satisfying its financial or other obligations under this Lease; (ii) the
proposed assignee of sublessee, in Landlord's reasonable opinion, is not
reputable and of good character; (iii) the portion of the Premises requested to
be subleased renders the balance of the Premises unleasable as a separate area;
(iv) Tenant is proposing a sublease at a subrental rate which is materially
less, in Landlord's reasonable documented opinion, than the then fair market
subrental rate for the portion of the Premises being subleased or assigned, or
Tenant is proposing to assign or sublease to an existing tenant within the
Building, or another prospect with whom Landlord or its partners, or their
affiliates are then negotiating and the Landlord has comparable space within a
two (2) mile radius of the Building to meet said party's needs; (v) the proposed
assignee or sublessee will cause Landlord's existing parking facilities to be
reasonably inadequate, or in violation of code requirements, or require Landlord
to increase the parking area or the number of parking spaces to meet code
requirements, or the nature of such party's business shall reasonably require
more than five (5) parking spaces per 1,000 rentable square feet of floor space,
or (vii) the nature of such party's proposed business operation would or might
reasonably permit or require the use of the Premises in a manner inconsistent
with the "Permitted Use " specified herein, would or might reasonably otherwise
be in conflict with express provisions of this Lease, would or might reasonably
violate the terms of any other lease for the Building, or would, in Landlord's
reasonable judgement, otherwise be incompatible with other tenancies in the
Building.

            (e) Any sums or other economic consideration received by Tenant as a
result of any subletting, assignment or license (except rental or other payments
received which are attributable to the amortization of the cost of leasehold
improvements made to the sublet or assigned portion of the premises by Tenant
for subtenant or assignee, and other reasonable expenses incident to the
subletting or assignment, including but not limited to standard leasing
commissions and reasonable attorneys' fees) whether denominated rentals under
the sublease or otherwise, which exceed, in the aggregate, the total sums which
Tenant is obligated to pay Landlord under this Lease (prorated to reflect
obligations allocable to that portion of the premises subject to such sublease
or assignment) shall be divided evenly between Landlord and Tenant, with
Landlord's portion being payable to Landlord as Additional Rental under this
Lease without affecting or reducing any other obligation of Tenant hereunder.

                                       17
<PAGE>

            (f) Regardless of Landlord's consent, no subletting or assignment
shall release Tenant of Tenant's obligation or alter the primary liability of
Tenant to pay the Rent and to perform all other obligations to be performed by
Tenant hereunder. The acceptance of rental by Landlord from any other person
shall not be deemed to be a waiver by Landlord of any provision hereof. Consent
to one assignment or subletting shall not be deemed consent to any subsequent
assignment or subletting. In the event of default by any assignee of Tenant or
any successor of Tenant in the performance of any of the terms hereof, Landlord
may proceed directly against Tenant without the necessity of exhausting remedies
against such assignee or successor.

            (g) In the event that (i) the Premises or any part thereof are
sublet and Tenant is in default under this Lease, or (ii) this Lease is assigned
by Tenant, then, Landlord may collect Rent from the assignee or subtenant and
apply the net amount collected to the rent herein reserved; but no such
collection shall be deemed a waiver of the provisions of this Article 12 with
respect to assignment and subletting, or the acceptance of such assignee or
subtenant as Tenant hereunder, or a release of Tenant from further performance
of the covenants herein contained.

            (h) In connection with each proposed assignment or subletting of the
Premises by Tenant to which Tenant must seek Landlord's consent, Tenant shall
pay to Landlord (i) an administrative fee of $250 per request (including
requests for a Landlord Waiver) in order to defer Landlord's administrative
expenses arising from such request, plus (ii) Landlord's reasonable attorneys'
fees not to exceed $2,500.

            (i) Notwithstanding anything in this Lease to the contrary, Tenant
may, after notice to, but without the consent of Landlord, assign this Lease to
an affiliated (i.e. an entity controlling, controlled by or under common control
with Tenant) corporation of Tenant or to a corporation to which it sells or
assigns all or substantially all of its assets or stock or with which it may be
consolidated or merged, provided such purchasing, consolidated, merged,
affiliated or subsidiary corporation shall, in writing, assume and agree to
perform all of the obligations of Tenant under this Lease, shall have a net
worth at least equal to $10,000,000 (each, an "Affiliate"), and it shall deliver
such assumption with a copy of such assignment to Landlord within thirty (30)
days thereafter, and provided further that Tenant shall not be released or
discharged from any liability under this Lease by reason of such assignment.

            (j) Notwithstanding anything in this Lease to the contrary, Tenant
may, after notice to, but without the consent of Landlord, sublet less than
twenty percent (20%) of the Premises for a term of less than three years (which
term may not end during the last two Lease Years) provided the following
conditions are satisfied: (1) such subtenant's proposed business operation would
not be inconsistent with the "Permitted Use " specified herein; (2) the portion
of the Premises requested to be subleased would not render the balance of the
Premises unleasable as a separate area; (3) the proposed subtenant is not an
existing tenant within the Building, or another prospect with whom Landlord or
its partners, or their affiliates are then negotiating and the Landlord has
comparable space within a ten (10) mile radius of the Building to meet said
party's needs and (4) each sublease is in writing and contains commercially
reasonable terms, including a requirement to post a cash security deposit in the
amount of not less than two months sub-rent. Tenant hereby assigns to Landlord
the absolute right to all such security deposits, and Landlord hereby grants
Tenant the license to hold and apply such security deposits which license shall
terminate automatically upon an Event of Default.

                                       18
<PAGE>

            (k) Anything in this Article 12 to the contrary notwithstanding, no
assignment or sublease shall be permitted under this Lease if Tenant is in
default or has previously defaulted two (2) times during the Term in connection
with any of its monetary obligations under this Lease.

         13. LANDLORD'S RIGHT OF ENTRY. Landlord and persons authorized by
Landlord may enter the Premises at all reasonable times upon reasonable advance
notice (except in the case of an emergency in which case no prior notice is
necessary) for the purpose of inspections, repairs, alterations to adjoining
space, appraisals, or other reasonable purposes; including enforcement of
Landlord's rights under this Lease. Landlord shall not be liable for
inconvenience to or disturbance of Tenant by reason of any such entry; provided,
however, that such entry and activities shall be done, so far as practicable, so
as to not unreasonably interfere with Tenant's use of the Premises and provided
that Landlord shall be responsible for any negligence or willful acts in
connection with such entry and activities. Provided, however, that such efforts
shall not require Landlord to use overtime labor unless Tenant shall pay for the
increased costs to be incurred by Landlord for such overtime labor. Landlord
also shall have the right to enter the Premises at all reasonable times after
giving at least twenty-four (24) house oral notice to Tenant, to exhibit the
Premises to any prospective purchaser, tenant and/or mortgagee.

         14. REPAIRS AND MAINTENANCE.

            (a) Except as specifically otherwise provided in subparagraphs (b)
and (c) of this Article, Tenant, at its sole cost and expense and throughout the
Term of this Lease, shall keep and maintain the Premises in good order and
condition, free of accumulation of dirt and rubbish, and shall promptly make all
non-structural repairs necessary to keep and maintain such good order and
condition. Landlord shall replace lights, ballasts, tubes, ceiling tiles,
outlets and similar equipment as required for repairs or replacement and the
charge or cost associates with same shall be included as part of Recognized
Expenses as set forth in Section 6. Landlord shall make such repairs or
replacements to the Premises within a reasonable time of notice to Landlord.
Tenant shall not use or permit the use of any portion of the Premises for
outdoor storage. When used in this Article 14, the term "repairs" shall include
replacements and renewals when necessary. All repairs made by Tenant shall
utilize materials and equipment which are at least equal in quality and
usefulness to those originally used in constructing the Building and the
Premises.

            (b) Landlord, throughout the Term of this Lease and at Landlord's
sole cost and expenses, shall make all necessary repairs to the footings and
foundations and the structural steel columns and girders forming a part of the
Premises.

            (c) Landlord shall maintain all HVAC systems, plumbing and electric
systems serving the Building and the Premises with the exception of any systems
installed as a Tenant Improvement or an Alteration such as supplemental HVAC
equipment ("Tenant's Specialized Systems"). Tenant shall maintain Tenant's
Specialized Systems at Tenant's sole cost and expense. Tenant's Allocated Share
of Landlord's cost for HVAC, electric and plumbing service, maintenance and
repairs, as limited under Article 6 with respect to capital expenditures, shall
be included as a portion of Recognized Expenses as provided in Article 6 hereof.

            (d) Landlord, throughout the Term of this Lease, shall make all
necessary repairs to the Building outside of the Premises and to the common
areas, including the roof, walls, exterior portions of the Premises and the
Building, utility lines, equipment and other utility facilities in the Building,
and to any driveways, sidewalks, curbs, loading, parking and landscaped areas,
and other exterior improvements for the Building; provided, however, that
Landlord shall have no responsibility to make any repairs unless and until
Landlord receives written notice of the need for such repair or Landlord has
actual knowledge of the need to make such repair. Tenant shall pay its Allocated
Share of the cost of all repairs, as limited under Article 6 with respect to
capital repairs, to be performed by Landlord pursuant to this Paragraph 14(d) as
Additional Rent as provided in Article 6 hereof.

            (e) Landlord shall keep and maintain all common areas appurtenant to
the Building and any sidewalks, parking areas, curbs and access ways adjoining
the Property in a clean and orderly condition, free of accumulation of dirt,
rubbish, snow and ice, and shall keep and maintain all landscaped areas in a
neat and orderly condition. Tenant shall pay its Allocated Share of the cost of
all work to be performed by Landlord pursuant to this Paragraph (e) as
Additional Rent as provided in Article 6 hereof.

            (f) Notwithstanding anything herein to the contrary, repairs to the
Premises, Building or Project and its appurtenant common areas made necessary by
a negligent or willful act or omission of Tenant or any employee, agent,
contractor, or invitee of Tenant shall be made at the sole cost and expense of
Tenant, except to the extent of insurance proceeds received by Landlord.

            (g) Landlord shall provide Tenant with janitorial services for the
Premises Monday through Friday of each week in accordance with the guidelines
set forth in Exhibit "D" attached hereto and the Tenant shall pay its Allocated
Share of the cost thereof as Additional Rent as provided in Article 6 hereof.
Tenant, at it's option, on ninety days prior written notice to Landlord, may
terminate Landlord's janitorial service. In the event Landlord is no longer
providing such services, Fixed Rent shall decrease by $.90 per rentable square
foot or the amount being billed for such services at such time, whichever is
greater.

         15. INSURANCE; SUBROGATION RIGHTS.

            (a) Tenant shall obtain and keep in force at all times during the
term hereof, at its own expense, comprehensive general liability insurance
including contractual liability and personal injury liability and all similar
coverage, with combined single limits of $3,000,000.00 on account of bodily
injury to or death of one or more persons as the result of any one accident or
disaster and on account of damage to property. Tenant shall also require its
movers to procure and deliver to Landlord a certificate of insurance naming
Landlord as an additional insured.

            (b) Tenant shall, at its sole cost and expense, maintain in full
force and effect on all Tenant's trade fixtures, equipment and personal property
on the Premises, a policy of all risk property insurance covering the full
replacement value of such property.

            (c) All insurance required hereunder shall not be subject to
cancellation without at least thirty (30) days prior notice to all insureds, and
shall name Landlord, Brandywine Realty Trust, Brandywine Operating Partnership,
L.C., Landlord's Agent and Tenant as insureds, as their interests may appear,
and, if requested by Landlord, shall also name as an additional insured any
mortgagee or holder of any mortgage which may be or become a lien upon any part
of the Premises. Prior to the commencement of the Term, Tenant shall provide
Landlord with certificates which evidence that the coverages required have been
obtained and that premiums have been paid in full for the policy periods. Tenant
shall also furnish to Landlord throughout the term hereof replacement
certificates, together with evidence of like paid premiums at least thirty (30)
days prior to the expiration dates of the then current policy or policies. All
the insurance required under this Lease shall be issued by insurance companies
authorized to do business in the Commonwealth of Pennsylvania with a financial
rating of at least an A-X as rated in the most recent edition of Best's
Insurance Reports and in business for the past five years. The limit of any such
insurance shall not limit the liability of Tenant hereunder. If Tenant fails to
procure and maintain such insurance, Landlord may, but shall not be required to,
procure and maintain the same, at Tenant's expense to be reimbursed by Tenant as
Additional Rent within ten (10) days of written demand. Any deductible under
such insurance policy or self-insured retention under such insurance policy in
excess of Twenty Thousand ($20,000) must be approved by Landlord in writing
prior to issuance of such policy. Tenant shall not self-insure without
Landlord's prior written consent. The policy limits set forth herein shall be
subject to periodic review, and Landlord reserves the right to require that
Tenant increase the liability coverage limits if, in the reasonable opinion of
Landlord, the coverage becomes inadequate or is less than commonly maintained by
tenants of similar buildings in the area making similar uses.

            (d) Landlord shall obtain and maintain the following insurance
during the Term of this Lease: (i) replacement cost insurance including all risk
perils on the Building and on the Project, (ii) builder's risk insurance for the
Landlord Work to be constructed by Landlord in the Project, and (iii)
comprehensive commercial liability insurance (including bodily injury and
property damage) covering Landlord's operations at the Project in amounts
reasonably required by the Landlord's lender or Landlord.

                                       21
<PAGE>

            (e) Each party hereto, and anyone claiming through or under them by
way of subrogation, waives and releases any cause of action it might have
against the other party and Landlord, Brandywine Realty Trust, Brandywine
Operating Partnership, L.P., and their respective employees, officers, members,
partners, trustees and agents, on account of any loss or damage that is insured
against under any insurance policy required to be obtained hereunder (to the
extent that such loss or damage is recoverable under such insurance policy) that
covers the Project, Building or Premises, Landlord's or Tenant's fixtures,
personal property, leasehold improvements or business and which names Landlord,
Brandywine Realty Trust and Brandywine Operating Partnership, L.P., or Tenant,
as the case may be, as a party insured. Each party hereto agrees that it will
cause its insurance carrier to endorse all applicable policies waiving the
carrier's right of recovery under subrogation or otherwise against the other
party. During any period while such waiver of right of recovery is in effect,
each party shall look solely to the proceeds of such policies for compensation
for loss, to the extent such proceeds are paid under such policies.

         16. INDEMNIFICATION. (a) Tenant shall defend, indemnify and hold
harmless Landlord, Brandywine Operating Partnership, L.P. and Brandywine Realty
Trust and their respective partners, officers, trustees, employees and agents
from and against any and all third-party claims, actions, damages, liability and
expense (including all reasonable attorney's fees, expenses and liabilities
incurred in defense of any such claim or any action or proceeding brought
thereon) arising from (i) any activity, work or things done, permitted or
suffered by Tenant or its agents, licensees or invitees in or about the Premises
or elsewhere contrary to the requirements of the Lease, (ii) any breach or
default in the performance of any obligation of Tenant's part to be performed
under the terms of this Lease, and (iii) any negligence or willful act of Tenant
or any of Tenant's agents, contractors, employees or invitees. Without limiting
the generality of the foregoing, Tenant's obligations shall include any case in
which Landlord, Brandywine Operating Partnership, L.P. or Brandywine Realty
Trust shall be made a party to any litigation commenced by or against Tenant,
its agents, subtenants, licensees, concessionaires, contractors, customers or
employees, in which event Tenant shall defend, indemnify and hold harmless
Landlord, Brandywine Operating Partnership, L.P., or Brandywine Realty Trust and
shall pay all costs, expenses and reasonable attorney's fees incurred or paid by
Landlord, Brandywine Operating Partnership, L.P., and Brandywine Realty Trust in
connection with such litigation, after notice to Tenant and Tenant's refusal to
defend such litigation, and upon notice from Landlord shall defend the same at
Tenant's expense by counsel satisfactory to Landlord.

            (b) Landlord shall defend, indemnify and hold harmless Tenant and
its employees and agents from and against any and all third-party claims,
actions, damages, liability and expense (including all attorney's fees, expenses
and liabilities incurred in defense of any such claim or any action or
proceeding brought thereon) arising from (i) any activity, work or things done,
permitted or suffered by Landlord in or about the Project or elsewhere contrary
to the requirements of the Lease, (ii) any breach or default in the performance
of any obligation on Landlord's part to be performed under the terms of this
Lease, and (iii) any negligence or willful act of Landlord or any of Landlord's
agents, contractors or employees, and in case Tenant shall be made a party to
any litigation commenced by or against Landlord, its agents, contractors or
employees, then Landlord shall defend, indemnify and hold harmless Tenant and
shall pay all costs, expenses and reasonable attorney's fees incurred or paid by
Tenant in connection with such litigation, after notice to Landlord and
Landlord's refusal to defend such litigation, and upon notice from Tenant shall
defend the same at Landlord's expense by counsel satisfactory to Tenant.
Landlord shall further indemnify and hold harmless Tenant from and against any
and all third-party claims, actions, damages, liability and expense (including,
without limitation, reasonable attorney's fees and disbursements) which may be
imposed upon or incurred by or asserted against Tenant by reason of loss of
life, personal injury and/or damage to property occurring in or about, or
arising out of, the Premises, adjacent sidewalks and loading platforms or areas
and common areas appurtenant to the Building occasioned by reason of any act or
omission of Landlord, its agents, contractors or employees.

                                       22
<PAGE>

         17. QUIET ENJOYMENT. Provided Tenant is not in default of the terms and
conditions of this Lease, including the payment of Fixed Rent and Additional
Rent, to be performed by Tenant, Tenant shall peaceably and quietly hold and
enjoy the Premises for the Term, without hindrance from Landlord, or anyone
claiming by through or under Landlord under and subject to the terms and
conditions of this Lease and of any mortgages now or hereafter affecting all of
or any portion of the Premises.

         18. FIRE DAMAGE.

            (a) Except as provided below, in case of damage to the Premises by
fire or other insured casualty, Landlord shall repair the damage. Such repair
work shall be commenced promptly following notice of the damage and completed
with due diligence, taking into account the time required for Landlord to effect
a settlement with and procure insurance proceeds from the insurer, except for
delays due to Force Majeure (as defined in Section 37), provided however, that
Landlord shall notify Tenant within five (5) business days following the onset
of a Force Majeure event.

            (b) Notwithstanding the foregoing, if (i) the damage is of a nature
or extent that, in Landlord's reasonable judgment (to be communicated to Tenant
promptly but in any event within thirty (30) days from the date of the
casualty), the repair and restoration work would require more than one hundred
eighty (180) consecutive days to complete after the casualty (assuming normal
work crews not engaged in overtime), or (ii) if more than thirty (30%) percent
of the total area of the Building is extensively damaged, either party shall
have the right to terminate this Lease and all the unaccrued obligations of the
parties hereto, by sending written notice of such termination to the other
within ten (10) days of Tenant's receipt of the notice from Landlord described
above. Such notice is to specify a termination date no less than fifteen (15)
days after its transmission.

            (c) If the insurance proceeds received by Landlord as dictated by
the terms and conditions of any financing then existing on the Building,
(excluding any rent insurance proceeds) would not be sufficient to pay for
repairing the damage or are required to be applied on account of any mortgage
which encumbers any part of the Premises or Building, or if the nature of loss
is not covered by Landlord's fire insurance coverage, Landlord may elect either
to (i) repair the damage as above provided notwithstanding such fact or (ii)
terminate this Lease by giving Tenant notice of Landlord's election as
aforesaid.

            (d) In the event Landlord has not completed restoration of the
Premises within one hundred eighty (180) days from the date of casualty (subject
to delay due to Force Majeure as set forth in subsection 18(a) above, Tenant may
terminate this Lease by written notice to Landlord within thirty (30) days
following the expiration of such 180 day period (as extended for reasons beyond
Landlord's control as provided above) unless, within thirty (30) business days
following receipt of such notice, Landlord has substantially completed such
restoration and delivered the Premises to Tenant for occupancy. Notwithstanding
the foregoing, in the event Tenant is responsible for the aforesaid casualty,
Tenant shall not have the right to terminate this Lease if Landlord is willing
to rebuild and restore the Premises.

                                       23
<PAGE>

            (e) In the event of damage or destruction to the Premises or any
part thereof, Tenant's obligation to pay Fixed Rent and Additional Rent shall be
equitably adjusted or abated as of the date of such fire or other casualty. Such
equitable adjustment or abatement shall take into account whether Tenant is able
to operate its business for it Permitted Uses at the Premises.

         19. SUBORDINATION; RIGHTS OF MORTGAGEE.

            (a) This Lease shall be subject and subordinate at all times to the
lien of any mortgages now or hereafter placed upon the Premises, Building and/or
Project and land of which they are a part without the necessity of any further
instrument or act on the part of Tenant to effectuate such subordination,
provided, however, that so long as Tenant or its successors or assigns is not in
default under any of the provisions of this Lease: (i) the interest of Tenant
and its successors, assigns and subtenants under this Lease shall not be
diminished or interfered with, (ii) Tenant, its successors, assigns and
subtenants may remain undisturbed and in quiet possession under this Lease, and
(c) no such rights shall be disturbed by any proceeding taken by the mortgagee
against Landlord or by foreclosure by the mortgagee. Tenant further agrees to
execute and deliver upon demand such further instrument or instruments
evidencing such subordination of this Lease to the lien of any such mortgage and
such further instrument or instruments of attornment as shall be reasonably
requested by any mortgagee or proposed mortgagee or by or by a ground lessor,
licensor or party to an agreement under any such ground lease, license or
agreement, respectively. Notwithstanding the foregoing, any mortgagee may at any
time subordinate its mortgage to this Lease, without Tenant's consent, by notice
in writing to Tenant, and thereupon this Lease shall be deemed prior to such
mortgage without regard to their respective dates of execution and delivery and
in that event such mortgagee shall have the same rights with respect to this
Lease as though it had been executed prior to the execution and delivery of the
mortgage.

            (b) In the event Landlord shall be or is alleged to be in default of
any of its obligations owing to Tenant under this Lease, Tenant agrees to give
to the holder of any mortgage (collectively the "Mortgagee") now or hereafter
placed upon the Premises, Building and/or Project, notice as may be reasonably
required by such Mortgagee.

            Landlord shall use its best efforts to deliver a subordination,
attornment and nondisturbance agreement ("Nondisturbance Agreement") from each
future Landlord's Mortgagee, on each such mortgagee's standard form, which shall
provide, inter alia, that the leasehold estate granted to Tenant under this
Lease will not be terminated or disturbed by reason of the foreclosure of the
mortgage held by Landlord's Mortgagee, so long as Tenant shall not be in default
under this Lease and shall pay all sums due under this Lease without offsets or
defenses thereto, except as specifically set forth herein, and shall fully
perform and comply with all of the terms, covenants and conditions of this Lease
on the part of Tenant to be performed and/or complied with, and in the event a
future mortgagee or its respective successor or assigns shall enter into and
lawfully become possessed of the Premises covered by this Lease and shall
succeed to the rights of Landlord hereunder, Tenant will attorn to the successor
as its landlord under this Lease and, upon the request of such successor
landlord, Tenant will execute and deliver an attornment agreement in favor of
the successor landlord.

                                       24
<PAGE>

         20. CONDEMNATION.

            (a) If more than twenty (20%) percent of the floor area of the
Premises is taken or condemned for a public or quasi-public use (a sale in lieu
of condemnation to be deemed a taking or condemnation for purposes of this
Lease), this Lease shall, at either party's option, terminate as of the date
title to the condemned real estate vests in the condemnor, and the Fixed Rent
and Additional Rent herein reserved shall be apportioned and paid in full by
Tenant to Landlord to that date and all rent prepaid for period beyond that date
shall forthwith be repaid by Landlord to Tenant and neither party shall
thereafter have any liability hereunder.

            (b) If less than twenty (20%) percent of the floor area of the
Premises is taken or if neither Landlord nor Tenant have elected to terminate
this Lease pursuant to the preceding sentence, Landlord shall do such work as
may be reasonably necessary to restore the portion of the Premises not taken to
tenantable condition for Tenant's uses provided however, if Landlord determines
that the net award/damages available for restoration of the Premises, Building
and/or Project will not be sufficient to pay the cost of restoration, or if the
condemnation damage award is required to be applied on account of any mortgage
which encumbers any part of the Premises, Building and/or Project, Landlord may
terminate this Lease by giving Tenant thirty (30) days prior notice specifying
the termination date which shall be the date title to the condemned real estate
vests in the condemnor.

            (c) If this Lease is not terminated after any such taking or
condemnation, the Fixed Rent and the Additional Rent shall be equitably reduced
in proportion to the area of the Premises which has been taken for the balance
of the Term.

            (d) If a part or all of the Premises shall be taken or condemned,
all compensation awarded upon such condemnation or taking shall go to Landlord
and Tenant shall have no claim thereto other than Tenant's damages associated
with moving, storage, equipment, trade fixtures, stationary and relocation; and
Tenant hereby expressly waives, relinquishes and releases to Landlord any claim
for damages or other compensation to which Tenant might otherwise be entitled
because of any such taking or limitation of the leasehold estate hereby created,
and irrevocably assigns and transfers to Landlord any right to compensation of
all or a part of the Premises or the leasehold estate.

         21. ESTOPPEL CERTIFICATE. Each party agrees at any time and from time
to time, within ten (10) days after the other party's written request, to
execute, acknowledge and deliver to the other party a written instrument in
recordable form certifying that this Lease is unmodified and in full force and
effect (or if there have been modifications, that it is in full force and effect
as modified and stating the modifications), and the dates to which Rent,

                                       25

<PAGE>

Additional Rent, and other charges have been paid in advance, if any, and
stating whether or not to the best knowledge of the party signing such
certificate, the requesting party is in default in the performance of any
covenant, agreement or condition contained in this Lease and, if so, specifying
each such default of which the signer may have knowledge. It is intended that
any such certification and statement delivered pursuant to this Article may be
relied upon by any prospective purchaser of the Project or any mortgagee thereof
or any assignee of Landlord's interest in this Lease or of any mortgage upon the
fee of the Premises or any part thereof.

         22. DEFAULT.

            (a) If:

                  (i) Tenant fails to pay any installment of Fixed Rent or any
amount of Additional Rent when due; provided, however, Tenant shall have a five
(5) business day cure period for Fixed Rent and Additional Rent to make such
payment without creating a default.

                  (ii) Tenant fails to observe or perform any of Tenant's other
non-monetary agreements or obligations herein contained within thirty (30) days
after written notice specifying the default, or the expiration of such
additional time period as is reasonably necessary to cure such default, provided
Tenant immediately commences and thereafter proceeds with all due diligence and
in good faith to cure such default,

                  (iii) Tenant makes any assignment for the benefit of
creditors,

                  (iv) a petition is filed or any proceeding is commenced
against Tenant or by Tenant under any federal or state bankruptcy or insolvency
law and such petition or proceeding is not dismissed within ninety (90) days,

                  (v) a receiver or other official is appointed for Tenant or
for a substantial part of Tenant's assets or for Tenant's interests in this
Lease,

                  (vi) any attachment or execution against a substantial part of
Tenant's assets or of Tenant's interests in this Lease remains unstayed or
undismissed for a period of more than twenty (20) days, or

                  (vii) a substantial part of Tenant's assets or of Tenant's
interest in this Lease is taken by legal process in any action against Tenant,
then, in any such event, an Event of Default shall be deemed to exist and Tenant
shall be in default hereunder.

            If an Event of Default shall occur, the following provisions shall
apply and Landlord shall have, in addition to all other rights and remedies
available at law or in equity, the rights and remedies set forth therein, which
rights and remedies may be exercised upon or at any time following the
occurrence of an Event of Default unless, prior to such exercise, Landlord shall
agree in writing with Tenant that the Event(s) of Default has been cured by
Tenant in all respects.

                                       26
<PAGE>

            (b) Acceleration of Rent. By notice to Tenant, Landlord shall have
the right to accelerate all Fixed Rent and all expense installments due
hereunder and otherwise payable in installments over the remainder of the Term,
and, at Landlord's option, any other Additional Rent to the extent that such
Additional Rent can be determined and calculated to a fixed sum; and the amount
of accelerated rent to the termination date, without further notice or demand
for payment, shall be due and payable by Tenant within five (5) days after
Landlord has so notified Tenant, such amount collected from Tenant shall be
discounted to present value using an interest rate of six percent (6%) per
annum. Additional Rent which has not been included, in whole or in part, in
accelerated rent, shall be due and payable by Tenant during the remainder of the
Term, in the amounts and at the times otherwise provided for in this Lease.

            Notwithstanding the foregoing or the application of any rule of law
based on election of remedies or otherwise, if Tenant fails to pay the
accelerated rent in full when due, Landlord thereafter shall have the right by
notice to Tenant, (i) to terminate Tenant's further right to possession of the
Premises and (ii) to terminate this Lease under subparagraph (b) below; and if
Tenant shall have paid part but not all of the accelerated rent, the portion
thereof attributable to the period equivalent to the part of the Term remaining
after Landlord's termination of possession or termination of this Lease shall be
applied by Landlord against Tenant's obligations owing to Landlord, as
determined by the applicable provisions of subparagraphs (c) and (d) below.

            (c) Termination of Lease. By notice to Tenant, Landlord shall have
the right to terminate this Lease as of a date specified in the notice of
termination, which termination date shall be at least thirty (30) days from the
date of Tenant's receipt of such notice, and in such case, Tenant's rights,
including any based on any option to renew, to the possession and use of the
Premises shall end absolutely as of the termination date; and this Lease shall
also terminate in all respects except for the provisions hereof regarding
Landlord's damages and Tenant's liabilities arising prior to, out of and
following the Event of Default and the ensuing termination.

            Following such termination and the notice of same provided above (as
well as upon any other termination of this Lease by expiration of the Term or
otherwise) Landlord immediately shall have the right to recover possession of
the Premises; and to that end, Landlord may enter the Premises and take
possession, without the necessity of giving Tenant any additional notice to quit
or any other further notice, with legal process or proceedings, and in so doing
Landlord may remove Tenant's property (including any improvements or additions
to the Premises which Tenant made, unless made with Landlord's consent which
expressly permitted Tenant to not remove the same upon expiration of the Term),
as well as the property of others as may be in the Premises, and make
disposition thereof in such manner as Landlord may deem to be commercially
reasonable and necessary under the circumstances.

            (d) Tenant's Continuing Obligations/Landlord's Reletting Rights.

                  (1) Unless and until Landlord shall have terminated this Lease
under subparagraph (b) above, Tenant shall remain fully liable and responsible
to perform all of the covenants and to observe all the conditions of this Lease
throughout the remainder of the Term to the early termination date; and, in
addition, Tenant shall pay to Landlord, upon demand and as Additional Rent, the
total sum of all costs, losses, damages and expenses, including reasonable
attorneys' fees, as Landlord incurs because of any Event of Default having
occurred.

                                       27
<PAGE>

                  (2) If Landlord either terminates Tenant's right to possession
without terminating this Lease or terminates this Lease and Tenant's leasehold
estate as above provided, then, subject to the provisions below, Landlord shall
have the unrestricted right to relet the Premises or any part(s) thereof to such
tenant(s) on such provisions and for such period(s) as Landlord may deem
appropriate. Landlord agrees, however, to use reasonable efforts to mitigate its
damages, provided that Landlord shall not be liable to Tenant for its inability
to mitigate damages if it shall endeavor to relet the Premises in like manner as
it offers other comparable vacant space or property available for leasing to
others in the Project of which the Building is a part or another property owned
by Landlord or its partners or affiliates within a two (2) mile radius of the
Building. If Landlord relets the Premises after such a default, the costs
recovered from Tenant shall be reallocated to take into consideration any
additional rent which Landlord receives from the new tenant which is in excess
to that which was owed by Tenant.

            (e) Landlord's Damages.

                  (1) The damages which Landlord shall be entitled to recover
from Tenant shall be the sum of:

                           (A) all Fixed Rent and Additional Rent accrued and
unpaid as of the termination date; and

                           (B) (i) all costs and expenses incurred by Landlord
in recovering possession of the Premises, including removal and storage of
Tenant's property, (ii) the costs and expenses of restoring the Premises to the
condition in which the same were to have been surrendered by Tenant as of the
expiration of the Term, and (iii) the costs of reletting commissions; and

                           (C) all Fixed Rent and Additional Rent (to the extent
that the amount(s) of Additional Rent has been then determined) otherwise
payable by Tenant over the remainder of the Term as reduced to present value.

Less deducting from the total determined under subparagraphs (A), (B) and (C)
all Rent and all other Additional Rent to the extent determinable as aforesaid,
(to the extent that like charges would have been payable by Tenant) which
Landlord receives from other tenant(s) by reason of the leasing of the Premises
or part during or attributable to any period falling within the otherwise
remainder of the Term.

                  (2) The damage sums payable by Tenant under the preceding
provisions of this paragraph (d) shall be payable on demand from time to time as
the amounts are determined; and if from Landlord's subsequent receipt of rent as
aforesaid from reletting, there be any excess payment(s) by Tenant by reason of
the crediting of such rent thereafter received, the excess payment(s) shall be
promptly refunded by Landlord to Tenant, without interest.

                  (3) Landlord may enforce the provisions of this Lease and may
enforce and protect the rights of Landlord hereunder by a suit or suits in
equity or at law for the specific performance of any covenant or agreement
contained herein, and for the enforcement of any other appropriate legal or
equitable remedy, including, without limitation, injunctive relief, and for
recovery of all moneys due or to become due from Tenant under any of the
provisions of this Lease.

            (f) Landlord's Right to Cure. Without limiting the generality of the
foregoing, if Tenant shall be in default in the performance of any of its
obligations hereunder, Landlord, without being required to give Tenant any
notice or opportunity to cure, may (but shall not be obligated to do so), in
addition to any other rights it may have in law or in equity, cure such default
on behalf of Tenant, and Tenant shall reimburse Landlord upon demand for any
sums paid or costs incurred by Landlord in curing such default, including
reasonable attorneys' fees and other legal expenses, together with interest at
10% per annum Rate from the dates of Landlord's incurring of costs or expenses.

            Tenant further waives the right to any notices to quit as may be
specified in the Landlord and Tenant Act of Pennsylvania, Act of April 6, 1951,
as amended, or any similar or successor provision of law to the extent the same
conflict with any other provision set forth herein, and agrees that five (5)
days notice shall be sufficient in any case where a longer period may be
statutorily specified.

            (g) Additional Remedies. In addition to, and not in lieu of any of
the foregoing rights granted to Landlord:

                  (i) WHEN THIS LEASE OR TENANT'S RIGHT OF POSSESSION SHALL BE
TERMINATED BY COVENANT OR CONDITION BROKEN, OR FOR ANY OTHER REASON, EITHER
DURING THE TERM OF THIS LEASE OR ANY RENEWAL OR EXTENSION THEREOF, AND ALSO WHEN
AND AS SOON AS THE TERM HEREBY CREATED OR ANY EXTENSION THEREOF SHALL HAVE
EXPIRED, IT SHALL BE LAWFUL FOR ANY ATTORNEY AS ATTORNEY FOR TENANT TO FILE AN
AGREEMENT FOR ENTERING IN ANY COMPETENT COURT AN ACTION TO CONFESS JUDGMENT IN
EJECTMENT AGAINST TENANT AND ALL PERSONS CLAIMING UNDER TENANT, WHEREUPON, IF
LANDLORD SO DESIRES, A WRIT OF EXECUTION OR OF POSSESSION MAY ISSUE FORTHWITH,
WITHOUT ANY PRIOR WRIT OF PROCEEDINGS, WHATSOEVER, AND PROVIDED THAT IF FOR ANY
REASON AFTER SUCH ACTION SHALL HAVE BEEN COMMENCED THE SAME SHALL BE DETERMINED
AND THE POSSESSION OF THE PREMISES HEREBY DEMISED REMAIN IN OR BE RESTORED TO
TENANT, LANDLORD SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT OR DEFAULTS,
OR UPON THE TERMINATION OF THIS LEASE AS HEREINBEFORE SET FORTH, TO BRING ONE OR
MORE ACTION OR ACTIONS AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE
SAID PREMISES.

            In any action to confess judgment in ejectment, Landlord shall first
cause to be filed in such action an affidavit made by it or someone acting for
it setting forth the facts necessary to authorize the entry of judgment, of
which facts such affidavit shall be conclusive evidence, and if a true copy of
this Lease (and of the truth of the copy such affidavit shall be sufficient
evidence) be filed in such action, it shall not be necessary to file the
original as a warrant of attorney, any rule of Court, custom or practice to the
contrary notwithstanding.

            ____________(INITIAL). TENANT WAIVER. TENANT SPECIFICALLY
ACKNOWLEDGES THAT TENANT HAS VOLUNTARILY, KNOWINGLY AND INTELLIGENTLY WAIVED
CERTAIN DUE PROCESS RIGHTS TO A PREJUDGMENT HEARING BY AGREEING TO THE TERMS OF
THE FOREGOING PARAGRAPHS REGARDING CONFESSION OF JUDGMENT. TENANT FURTHER
SPECIFICALLY AGREES THAT IN THE EVENT OF DEFAULT, LANDLORD MAY PURSUE MULTIPLE
REMEDIES INCLUDING OBTAINING POSSESSION PURSUANT TO A JUDGMENT BY CONFESSION. IN
SUCH EVENT AND SUBJECT TO THE TERMS SET FORTH HEREIN, LANDLORD SHALL PROVIDE
FULL CREDIT TO TENANT FOR ANY MONTHLY CONSIDERATION WHICH LANDLORD RECEIVES FOR
THE LEASED PREMISES IN MITIGATION OF ANY OBLIGATION OF TENANT TO LANDLORD FOR
THAT MONEY. FURTHERMORE, TENANT SPECIFICALLY WAIVES ANY CLAIM AGAINST LANDLORD
AND LANDLORD'S COUNSEL FOR VIOLATION OF TENANT'S CONSTITUTIONAL RIGHTS IN THE
EVENT THAT JUDGMENT IS CONFESSED PURSUANT TO THIS LEASE.

            (h) Interest on Damage Amounts. Any sums payable by Tenant
hereunder, which are not paid after the same shall be due, shall bear interest
from that day until paid at the rate of four (4%) percent over the then Prime
Rate as published daily under the heading of "Money Rates" in The Wall Street
Journal, unless such rate be usurious as applied to Tenant, in which case the
highest permitted legal rate shall apply (the "Default Rate").

            (i) Landlord's Statutory Rights. Landlord shall have all rights and
remedies now or hereafter existing at law or in equity with respect to the
enforcement of Tenant's obligations hereunder and the recovery of the Premises.
No right or remedy herein conferred upon or reserved to Landlord shall be
exclusive of any other right or remedy, but shall be cumulative and in addition
to all other rights and remedies given hereunder or now or hereafter existing at
law. Landlord shall be entitled to injunctive relief in case of the violation,
or attempted or threatened violation, of any covenant, agreement, condition or
provision of this Lease, or to a decree compelling performance of any covenant,
agreement, condition or provision of this Lease.

            (j) Remedies Not Limited. Nothing herein contained shall limit or
prejudice the right of Landlord to exercise any or all rights and remedies
available to Landlord by reason of default or to prove for and obtain in
proceedings under any bankruptcy or insolvency laws, an amount equal to the
maximum allowed by any law in effect at the time when, and governing the
proceedings in which, the damages are to be proved, whether or not the amount be
greater, equal to, or less than the amount of the loss or damage referred to
above.

                                       30

<PAGE>

            (k) No Waiver by Landlord. No delay or forbearance by Landlord in
exercising any right or remedy hereunder, or Landlord's undertaking or
performing any act or matter which is not expressly required to be undertaken by
Landlord shall be construed, respectively, to be a waiver of Landlord's rights
or to represent any agreement by Landlord to undertake or perform such act or
matter thereafter. Waiver by Landlord of any breach by Tenant of any covenant or
condition herein contained (which waiver shall be effective only if so expressed
in writing by Landlord) or failure by Landlord to exercise any right or remedy
in respect of any such breach shall not constitute a waiver or relinquishment
for the future of Landlord's right to have any such covenant or condition duly
performed or observed by Tenant, or of Landlord's rights arising because of any
subsequent breach of any such covenant or condition nor bar any right or remedy
of Landlord in respect of such breach or any subsequent breach. Landlord's
receipt and acceptance of any payment from Tenant which is tendered not in
conformity with the provisions of this Lease or following an Event of Default
(regardless of any endorsement or notation on any check or any statement in any
letter accompanying any payment) shall not operate as an accord and satisfaction
or a waiver of the right of Landlord to recover any payments then owing by
Tenant which are not paid in full, or act as a bar to the termination of this
Lease and the recovery of the Premises because of Tenant's previous default.

         23. LANDLORD'S LIEN. In addition to any applicable common law or
statutory lien, none of which are to be deemed waived by Landlord, Landlord
shall have, at all times, and Tenant has or shall hereby grant to Landlord, a
valid lien and security interest to secure payment of all rentals and other sums
of money becoming due hereunder from Tenant, and to secure payment of any
damages or loss which Landlord may suffer by reason of the breach by Tenant of
any covenant, agreement or condition contained herein, upon all goods, wares,
equipment, fixtures, furniture, improvements and other personal property of
Tenant which may hereafter be situated on the Premises, and all proceeds
therefrom, and such property shall not be removed therefrom without the consent
of Landlord until all arrearage in Rent as well as any and all other sums of
money then due to Landlord hereunder shall first have been paid and discharged
and all the covenants, agreements and conditions hereof have been fully complied
with and performed by Tenant. Landlord covenants and agrees to subordinate the
lien granted hereunder to any commercial lender which Tenant grants a security
interest. Upon the occurrence of an Event of Default by Tenant, but subject to
Tenant's lender rights, if any, after the expiration of all stated notice and
cure periods, Landlord may, in addition to any other remedies provided herein,
peaceably enter upon the Premises and take possession of any and all goods,
wares, equipment, fixtures, furniture, improvements and other personal property
of Tenant situated on the Premises, without liability for trespass or
conversion, and sell the same at public or private sale, with or without having
such property at the sale, after giving Tenant reasonable notice of time and
place of any public sale or of the time after which any private sale is to be
made, at which sale Landlord or its assigns may purchase unless otherwise
prohibited by law. Unless otherwise provided by law, and without intending to
exclude any other manner of giving Tenant reasonable notice, the requirement of
reasonable notice shall be met if such notice is given in the manner prescribed

                                       31

<PAGE>

in Article 28 of this Lease at least five (5) days before the time of sale. The
proceeds from any such disposition, less all expenses connected with the taking
of possession, holding and selling of the property (including reasonable
attorney's fees and other expenses), shall be applied as a credit against the
indebtedness secured by the security interest granted in this Article 23. Any
surplus shall be paid to Tenant or as otherwise required by law; and Tenant
shall pay any deficiencies forthwith. Upon request by Landlord, Tenant agrees to
execute and deliver to Landlord a financing statement in form sufficient to
perfect the security interest of Landlord in the aforementioned property and
proceeds thereof under the provisions of the Uniform Commercial Code in force in
the Commonwealth of Pennsylvania. Notwithstanding the foregoing, the parties
acknowledge and agree that Tenant's lender may have superior rights to the
property noted herein. Tenant shall use its reasonable efforts to obtain, within
forty-five (45) days of the date hereof, a waiver of all such rights from its
lender in this regard, and, failing to obtain such waiver, that Tenant shall use
its best efforts to obtain from such lender, the right to grant a subordinated
lien to Landlord in such goods, second only to the lien of such lender.

            Provided no Event of Default shall exist and remain uncured,
Landlord agrees to execute from time to time, on Landlord's standard form, a
Landlord's Waiver of Liens in conjunction with the financing of Tenant's trade
fixtures, machinery or equipment. For so long as no Event of Default shall exist
and remain uncured, Tenant shall have the right to remove and/or replace any
trade fixtures, machinery and/or equipment owned or leased by Tenant; provided
that Tenant shall promptly repair and restore any and all damage to the Premises
or the Building sustained or incurred in connection with the installation,
moving or removal of such items.

         24. LANDLORD'S REPRESENTATIONS AND WARRANTIES. Landlord represents and
warrants to Tenant that: (a) Landlord is the fee owner of the Building and the
Project; (b) Landlord has the authority to enter into this Lease and perform all
of its obligations hereunder; and (c) as of Lease Commencement Date the Project
shall be in compliance with all applicable laws, ordinances, orders, notices,
rules and regulations of federal, state and local authorities and the Tenant
Improvements shall have been completed in a good and workmanlike manner in
accordance with the plans and specifications, as may be amended in accordance
with this Lease.

         25. SURRENDER. Tenant shall, at the expiration of the Term, promptly
quit and surrender the Premises in good order and condition and in conformity
with the applicable provisions of this Lease, excepting only reasonable wear and
tear and damage by fire or other insured casualty. Tenant shall have no right to
hold over beyond the expiration of the Term and in the event Tenant shall fail
to deliver possession of the Premises as herein provided, such occupancy shall
not be construed to effect or constitute other than a tenancy at sufferance.
During the first thirty (30) days beyond the expiration of the Term the amount
of rent owed to Landlord by Tenant shall automatically become one hundred-fifty
percent (150%) the sum of the Rent as those sums are at that time calculated
under the provisions of the Lease. If Tenant fails to surrender the space within
thirty (30) days of the termination date, Landlord may elect to automatically
extend the Term for an additional month or additional year, at Landlord's
option, with a Rent of two hundred percent (200%) the sum of the Rent as those
sums are at that time calculated under the provisions of the Lease. The
acceptance of rent by Landlord or the failure or delay of Landlord in notifying
or evicting Tenant following the expiration or sooner termination of the Term
shall not create any tenancy rights in Tenant and any such payments by Tenant
may be applied by Landlord against its costs and expenses, including attorney's
fees incurred by Landlord as a result of such holdover.

                                       32

<PAGE>

         26. RULES AND REGULATIONS. Tenant agrees that at all times during the
terms of this Lease (as same may be extended) it, its employees, agents,
invitees and licenses shall comply with all rules and regulations specified on
Exhibit "C" attached hereto and made a part hereof, together with all reasonable
Rules and Regulations as Landlord may from time to time promulgate provided they
do not increase the financial burdens of Tenant or unreasonably restrict
Tenant's rights under this Lease are applied in non-discriminatory manner to all
tenants of the Building. Landlord shall provide Tenant with appropriate prior
written notice of any changes or additions to the Rules and Regulations and
Tenant's right to dispute the reasonableness of any changes in or additions to
the Rules and Regulations shall be deemed waived unless asserted to Landlord
within fifteen (15) business days after Landlord shall have given Tenant such
written notice. In case of any conflict or inconsistency between the provisions
of this Lease and any Rules and Regulations, the provisions of this Lease shall
control. Landlord shall have no duty or obligation to enforce any Rule and
Regulation, or any term, covenant or condition of any other lease, against any
other tenant, and Landlord's failure or refusal to enforce any Rule or
Regulation or any term, covenant of condition of any other lease against any
other tenant shall be without liability of Landlord to Tenant. However, if
Landlord does enforce Rules or Regulations, Landlord shall endeavor to enforce
same equally in a non-discriminatory manner.

         27. GOVERNMENTAL REGULATIONS.

            (a) Tenant shall, in the use and occupancy of the Premises and the
conduct of Tenant's business or profession therein, at all times comply with all
applicable laws, ordinances, orders, notices, rules and regulations of the
federal, state and municipal governments, or any of their departments and the
regulations of the insurers of the Premises, Building and/or Project.

            (b) Without limiting the generality of the foregoing, Tenant shall

taxes, income taxes and other taxes, assessments, duties, impositions and
similar charges which are or may be assessed, levied or imposed upon Tenant and

property therein or against Tenant's leasehold estate.

            (c) Landlord shall be responsible for compliance with Title III of
the Americans with Disabilities Act of l990, 42 U.S.C. ss.12181 et seq. and its
regulations, (collectively, the "ADA") (i) as to the design and construction of
interior and exterior common areas (e.g. lobbies, restrooms, sidewalks and
parking areas) of the Project and (ii) with respect to the initial design and
construction by Landlord of Tenant Improvements (as defined in Article 4
hereof). Except as set forth above in the initial sentence hereto, Tenant shall
be responsible for compliance with the ADA in all other respects concerning the
use and occupancy of the Premises, which compliance shall include, without
limitation (i) provision for full and equal enjoyment of the goods, services,
facilities, privileges, advantages or accommodations of the Premises as
contemplated by and to the extent required by the ADA, (ii) compliance relating
to requirements under the ADA or amendments thereto arising after the date of
this Lease and (iii) compliance relating to the design, layout, renovation,

<PAGE>

         28. NOTICES. Wherever in this Lease it shall be required or permitted
that notice or demand be given or served by either party to this Lease to or on
the other party, such notice or demand shall be deemed to have been duly given
or served if in writing and either: (i) delivered by pre-paid nationally
recognized overnight courier service (e.g. Federal Express) with evidence of
receipt required for delivery; or (ii) forwarded by Registered or Certified
mail, return receipt requested, postage prepaid; in all such cases addressed to
the parties at the addresses set forth in Article 1(l) hereof. Each such notice
shall be deemed to have been given to or served upon the party to which
addressed on the date the same is delivered or delivery is refused. Either party
hereto may change its address to which said notice shall be delivered or mailed
by giving written notice of such change to the other party hereto, as herein
provided.

         29. BROKERS. Tenant represents and warrants to Landlord that Tenant has
had no dealings, negotiations or consultations with respect to the Premises or
this transaction with any broker or finder other than the Broker identified in
Article 1(k); and that otherwise no broker or finder called the Premises to
Tenant's attention for lease or took any part in any dealings, negotiations or
consultations with respect to the Premises or this Lease. Each party agrees to
indemnify and hold the other harmless from and against all liability, cost and
expense, including reasonable attorney's fees and court costs, arising out of
any misrepresentation or breach of warranty under this Article. Landlord agrees
to pay any commission due and owing to Broker in accordance with a separate
commission agreement entered into between Landlord and Broker.

         30. CHANGE OF BUILDING/PROJECT NAME. Landlord reserves the right at any
time and from time to time to change the name by which the Building and/or
Project is designated; provided Tenant's signage remain on the Building.
Landlord agrees to pay for the reasonably documented costs of stationery charges
(including letterhead and cards) necessitated by any such name change.

         31. LANDLORD'S LIABILITY. Landlord's obligations hereunder shall be
binding upon Landlord only for the period of time that Landlord is in ownership
of the Building; and, upon termination of that ownership, Tenant, except as to
any obligations which are then due and owing, shall look solely to Landlord's
successor in interest in the Building for the satisfaction of each and every
obligation of Landlord hereunder, provided that the transferee assumed all
Landlord's obligations hereunder in writing. Landlord shall have no personal
liability under any of the terms, conditions or covenants of this Lease and
Tenant shall look solely to the equity, proceeds (which may include refinancing
proceeds), rents and profits of Landlord in the Building of which the Premises
form a part for the satisfaction of any claim, remedy or cause of action
accruing to Tenant as a result of the breach of any section of this Lease by
Landlord. In addition to the foregoing, no recourse shall be had for an
obligation of Landlord hereunder, or for any claim based thereon or otherwise in
respect thereof, against any past, present or future trustee, member, partner,
shareholder, officer, director, partner, agent or employee of Landlord, whether
by virtue of any statute or rule of law, or by the enforcement of any assessment
or penalty or otherwise, all such other liability being expressly waived and
released by Tenant with respect to the above-named individuals and entities.

                                       34
<PAGE>

         32. AUTHORITY. Tenant represents and warrants that (a) Tenant is duly
organized, validly existing and is legally authorized to do business in the
Commonwealth of Pennsylvania, and (b) the persons executing this Lease are duly
authorized to execute and deliver this Lease on behalf of Tenant.

         33. NO OFFER. The submission of the Lease by Landlord to Tenant for
examination does not constitute a reservation of or option for the Premises or
of any other space within the Building or in other buildings owned or managed by
Landlord or its affiliates. This Lease shall become effective as a Lease only
upon the execution and legal delivery thereof by both parties hereto

         34. RENEWAL. Provided Tenant is not in default of any obligations under
this Lease, nor defaulted more than twice on any monetary obligation in excess
of $500,000 in the aggregate and Tenant is occupying at least 75% of the
Building and the Lease is in full force and effect, Tenant shall have the right
to renew this Lease for two (2) term(s) of five years each beyond the end of the
initial Term (each, a "Renewal Term"). Tenant shall furnish written notice of
intent to renew one (1) year prior to the expiration of the applicable Term,
failing which, such renewal right shall be deemed waived; time being of the
essence. The terms and conditions of this Lease during each Renewal Term shall
remain unchanged except that the annual Fixed Rent for each Renewal Term shall
be the greater of (i) the Fixed Rent for the term expiring, and (ii) Fair Market
Rent (as such term is hereinafter defined). All factors regarding Additional
Rent shall remain unchanged, however Tenant shall be entitled to a five dollar
($5.00) per rentable square foot Tenant Allowance. Anything herein contained to
the contrary notwithstanding, Tenant shall have no right to renew the term
hereof other than or beyond the two (2) consecutive five (5) year terms
hereinabove described. It shall be a condition of each such Renewal Term that
Landlord and Tenant shall have executed, not less than nine (9) months prior to
the expiration of the then expiring term hereof, an appropriate amendment to
this Lease, in form and content satisfactory to each of them, which shall not
contain a material change (other than the terms of the renewal), memorializing
the extension of the term hereof for the next ensuing Renewal Term.

            For purposes of this Lease, "Fair Market Rent" shall mean the base
rent, for comparable space, net of all free or reduced rent periods, work
letters, cash allowances, fit-out periods and other tenant inducement
concessions however denominated except as hereinafter provided. In determining
the Fair Market Rent, Landlord, Tenant and any appraiser shall take into account
applicable measurement and the loss factors, applicable lengths of lease term,
differences in size of the space demised, the location of the Building and
comparable buildings, amenities in the Building and comparable buildings, the
ages of the Building and comparable buildings, differences in base years or stop
amounts for operating expenses and tax escalations and other factors normally
taken into account in determining Fair Market Rent. The Fair Market Rent shall
reflect the level of improvement to be made by Landlord to the space and the
Recognized Expenses and Taxes under this Lease. If Landlord and Tenant cannot
agree on the Fair Market Rent, the Fair Market Rent shall be established by the
following procedure: (1) Tenant and Landlord shall agree on a single MAI

                                       35

<PAGE>

certified appraiser who shall have a minimum of ten (10) years experience in
real estate leasing in the market in which the Premises is located and who has
not conducted within the previous five (5) years and does not presently conduct
and does not anticipate conducting business in the future with either Tenant or
Landlord, (2) Landlord and Tenant shall each notify the other (but not the
appraiser), of its determination of such Fair Market Rent and the reasons
therefor, (3) during the next seven (7) days both Landlord and Tenant shall
prepare a written critique of the other's determination and shall deliver it to
the other party, (4) on the tenth (10th) day following delivery of the critiques
to each other, Landlord's and Tenant's determinations and critiques (as
originally submitted to the other party, with no modifications whatsoever) shall
be submitted to the appraiser, who shall decide whether Landlord's or Tenant's
determination of Fair Market Rent is more correct. The determinations so chosen
shall be the Fair Market Rent. The appraiser shall not be empowered to choose
any number other than the Landlord's or Tenant's. The fees of the appraiser
shall be paid by the non-prevailing party.

         35. ROOF RIGHTS. So long as it (i) does not impact Landlord's roof
warranty and (ii) complies with all applicable laws, rules and regulations,
Tenant, at its sole cost and expense, shall have access to the roof of the
Building in designated areas mutually agreed upon for the purpose of
installation of microwave satellite, antenna and other communications devices or
supplemental HVAC units and venting and ducting for office uses (the "Roof
Equipment"). Tenant shall use its best efforts to utilize US Realtel to provide
such services. Nothing herein shall obligate Tenant to use US Realtel.
Notwithstanding the foregoing, all such Roof Equipment shall be for the sole
benefit of Tenant and Landlord, shall relate specifically to Tenant's use of the
Premises, and shall not be used as a switching station, amplification station or
by other tenants or third parties. Tenant shall make a request for approval of
the Roof Equipment hereunder by submission of specific plans and specifications
for the work to be performed by Tenant to Landlord at least thirty (30) days
prior to the proposed installation. Landlord shall respond in writing within ten
(10) business days from receipt of said plans and specifications, advising
Tenant of approved contractors and those portions of the work that are
acceptable and disapproving those portions of the work that are, in Landlord's
judgment, reasonably exercised, unacceptable and with respect to the plans,
specifying in detail the nature of Landlord's objection. Tenant shall be solely
responsible for all damages caused by installation, maintenance and/or removal
of its Roof Equipment and Tenant shall promptly repair any of the foregoing
damage caused to the roof by said installation, removal or maintenance of said
Roof Equipment and with respect to damage caused by removal of such Equipment
prior to the expiration or early termination of this Lease unless directed in
writing by Landlord otherwise. Landlord shall be named as an additional insured
on all Tenant insurance relating to the Roof Equipment. All installation,
repair, replacement and modification of the Roof Equipment shall be done only
after receipt of Landlord's written approval of such installation, repair,
replacement or modification; shall use only those contractors previously
approved in writing by Landlord; and shall be in accordance with the Rules and
Regulations set forth herein.

         36. RELOCATION. Intentionally Omitted.

transfer to such successor and/or assignee has first been obtained or/as

any manner other than by an agreement in writing signed by both parties hereto
or their respective successors in interest. Without in any way limiting the
generality of the foregoing, this Lease can only be extended pursuant to the
terms hereof, and in Tenant's case, with the terms hereof, and in Tenant's case,
with the due exercise of an option (if any) contained herein or a formal
agreement signed by both Landlord and Tenant specifically extending the term. No
negotiations, correspondence by Landlord or offers to extend the term shall be
deemed an extension of the termination date for any period whatsoever.

            g. Counterparts. This Lease may be executed in any number of
counterparts, each of which when taken together shall be deemed to be one and
the same instrument.

            h. Telefax Signatures. The parties acknowledge and agree that

            i. Calculation of Time. In computing any period of time prescribed
or allowed by any provision of this Lease, the day of the act, event or default
from which the designated period of time begins to run shall not be included.
The last day of the period so computed shall be included, unless it is a
Saturday, Sunday or a legal holiday, in which event the period runs until the
end of the next day which is not a Saturday, Sunday, or legal holiday. Unless
otherwise provided herein, all Notices and other periods expire as of 5:00 p.m.
(local time in Newtown Square, Pennsylvania) on the last day of the Notice or
other period.

            j. No Merger. There shall be no merger of this Lease or of the
leasehold estate hereby created with the fee estate in the Premises or any part
thereof by reason of the fact that the same person, firm, corporation, or other
legal entity may acquire or hold, directly or indirectly, this Lease of the
leasehold estate and the fee estate in the Premises or any interest in such fee
estate, without the prior written consent of Landlord's mortgagee.

            k. Time of the Essence. TIME IS OF THE ESSENCE IN ALL PROVISIONS OF
THIS LEASE, INCLUDING ALL NOTICE PROVISIONS TO BE PERFORMED BY OR ON BEHALF OF
TENANT AND LANDLORD.

            l. Recordation of Lease. Tenant shall not record this Lease without
the written consent of Landlord. Landlord agrees, upon Tenant's request, to
execute a short form of this Lease within thirty (30) days after the execution
and delivery of this Lease provided that the Memorandum of Lease provides that
upon the expiration of the Term of this Lease for any reason, the Memorandum of
Lease shall be deemed automatically terminated without the requirement of any
further action by either party hereto. Tenant may record such short form lease
at its sole cost and expense. The provisions of this Lease shall control,
however, with regard to any omissions from said short form, or with respect to
any provisions hereof which may be in conflict with such short form.

            m. Accord and Satisfaction. No payment by Tenant or receipt by
Landlord of a lesser amount than any payment of Fixed Rent or Additional Rent
herein stipulated shall be deemed to be other than on account of the earliest
stipulated Fixed Rent or Additional Rent due and payable hereunder, nor shall
any endorsement or statement or any check or any letter accompanying any check
or payment as Rent be deemed an accord and satisfaction. Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of such Rent or pursue any other right or remedy provided for in this
Lease, at law or in equity.

            n. No Partnership. Landlord does not, in any way or for any purpose,
become a partner of Tenant in the conduct of its business, or otherwise, or
joint venturer or a member of a joint enterprise with Tenant. This Lease
establishes a relationship solely of that of a landlord and tenant.

            o. No Presumption Against Drafter. Landlord and Tenant understand,
agree, and acknowledge that: (i) this Lease has been freely negotiated by both
parties; and (ii) that, in the event of any controversy, dispute, or contest
over the meaning, interpretation, validity, or enforceability of this Lease, or
any of its terms or conditions, there shall be no inference, presumption, or
conclusion drawn whatsoever against either party by virtue of that party having
drafted this Lease or any portion thereof.

                                       38
<PAGE>

            q. Force Majeure. If by reason of strikes or other labor disputes,
fire or other casualty (or reasonable delays in adjustment of insurance),
accidents, orders or regulations of any Federal, State, County or Municipal
authority, or any other cause beyond Landlord's reasonable control, Landlord is
unable to furnish or is delayed in furnishing any utility or service required to
be furnished by Landlord under the provisions of this Lease or is unable to
perform or make or is delayed in performing or making any installations,
decorations, repairs, alterations, additions or improvements, or is unable to
fulfill or is delayed in fulfilling any of Landlord's other obligations under
this Lease (collectively, "Force Majeure") and provided that Landlord shall
notify Tenant within five (5) business days following the onset of a Force
Majeure event), no such inability or delay shall constitute an actual or
constructive eviction, in whole or in part, or entitle Tenant to any abatement
or diminution of Fixed Rent, or relieve Tenant from any of its obligations under
this Lease, or impose any liability upon Landlord or its agents, by reason of
inconvenience or annoyance to Tenant, or injury to or interruption of Tenant's
business, or otherwise. Notwithstanding the foregoing, if the Premises is
without electric or any other utility service for more than five (5) consecutive
business days and due to the foregoing Tenant is unable to conduct all or a
substantial portion of Tenant's normal business operations therein, then the
Rent shall equitably abate until such electric or other utility is restored to
the Premises, provided however, that in the event such interruption or delay of
service of such utility is substantially due to an act or omission of Tenant or
Tenant's agents, employees, contractors or invitees or an overload of the
Building's capacity for such utility by any of such foregoing entities or
persons, the foregoing abatement shall not apply.

         38. CONSENT TO JURISDICTION. Tenant hereby consents to the exclusive
jurisdiction of the state courts located in Bucks, Montgomery, Delaware and
Philadelphia County and to the federal courts located in the Eastern District of
Pennsylvania.

         39. LANDLORD'S DEFAULT. If Landlord shall be in default in the
performance of any of its obligations under this Lease which default continues
for a period of more than thirty (30) days after receipt of written notice from
Tenant specifying such default, or if such default is of a nature to require
more than thirty (30) days for remedy and continues beyond the time reasonably
necessary to cure (and Landlord has not undertaken procedures to cure the
default within such thirty (30) day period and diligently pursued such efforts
to complete such cure), Tenant may, in addition to any other remedy available at
law or in equity, upon at least five (5) business days prior written notice,
incur any reasonably necessary expense to perform the obligation of Landlord
specified in such notice and deduct such expense from the Fixed Rent. Tenant
shall have all rights and remedies now or hereafter existing at law or in equity
with respect to the enforcement of Landlord's obligations hereunder. No right or
remedy herein conferred upon or reserved to Tenant shall be exclusive of any
other right or remedy, but shall be cumulative and in addition to all other
rights and remedies given hereunder or now or hereafter existing at law. Nothing
herein contained shall limit or prejudice the right of Tenant to exercise any or
all rights and remedies available to Tenant by reason of default or to prove for
and obtain in proceedings under any bankruptcy or insolvency laws, an amount
equal to the maximum allowed by any law in effect at the time when, and
governing the proceedings in which, the damages are to be proved, whether or not
the amount be greater, equal to, or less than the amount of the loss or damage
referred to above. No delay or forbearance by Tenant in exercising any right or
remedy hereunder, or Tenant's undertaking or performing any act or matter which
is not expressly required to be undertaken by Tenant shall be construed,
respectively, to be a waiver of Tenant's rights or to represent any agreement by
Tenant to undertake or perform such act or matter thereafter.

                                       39

         40. UNTENANTABILITY OF PREMISES. After the Commencement Date, in the
event the Premises are Untenantable (as defined herein) for any reason other
than as set forth in Article 18 or 20, and such Untenantablilty continues for
more than five (5) consecutive business days and Landlord and Tenant anticipate
that the same shall continue for more than thirty days, then Landlord shall use
best efforts to provide for Tenant premises in another building owned by
Landlord or its affiliate under the same lease terms as set forth herein on a
temporary basis for so long as the Premises remain Untenantable. If Tenant
elects to relocate, then all costs associated with such relocation shall be
borne by Tenant. Rent shall be abated for the Premises during the period the
Premises remain Untenantable and in no event shall Tenant be required to pay
rent to Landlord on both the Premises and any temporary space owned by Landlord
or its affiliate during such period the Premises are Untenantable. Upon the
correction of the condition making the Premises Untenantable, Tenant shall
resume possession of the Premises for its Permitted Uses. The Premises shall be
deemed "Untenantable" in the event the Premises can not be reasonably used by
Tenant for its Permitted Uses. This provision shall not apply if the condition
causing the Untenantability resulted from an act or omission of Tenant, its
employees or invitees.

         41. RIGHT TO PURCHASE. Provided no Event of Default has occurred and is
continuing, Tenant shall have the option to purchase the Project during the
first three months of the Term for a purchase price of Twenty Two Million
Dollars ($22,000,000) by providing at least one hundred eighty (180) days prior
written notice to Landlord ("Option Notice"). Closing may occur at any time
prior to the end of the third month of the Term and the Option Notice must be
received at least 180 days prior to the Closing Date. In order for the Option
Notice to be effective, Tenant must within five (5) days of sending the Option
Notice, post with Fidelity National Title Insurance Company, M. Gordon Daniels,
Esquire ("Escrow Agent") a deposit in the amount of One Million Dollars
($1,000,000) by good check ("Deposit"). The Deposit shall be held by Escrow
Agent in a federally-insured, segregated money market account at an institution
to be designated by Tenant until the Closing Date. Interest on the Deposit shall
be credited to Tenant at settlement, or paid to the party otherwise entitled to
the Deposit. The Deposit is non-refundable unless the settlement fails to occur
by reason of Landlord's failure to deliver title as required hereunder or
Landlord's failure to comply with the provisions of this Article 41. At
settlement, the Deposit shall be credited toward the purchase price. Failure to
post the Deposit as set forth herein shall constitute a default under this
Article 41 and this Lease.

            A. Upon the exercise by Tenant of this option, the provisions of
this Article 41 shall be construed as if it constituted an agreement of sale
between the parties whereby Landlord shall agree to sell and Tenant shall agree
to purchase the Project upon the following terms and conditions:

                                       40
<PAGE>

                  i. Settlement for the purchase of the Project shall be held at
Brandywine Realty Trust, 14 Campus Boulevard, Suite 100, Newtown Square, PA
19073 at 10:00 a.m. on the one hundred and eightieth day following the giving of
the Option Notice but in no event after the last day of the third month of the
Term ("Closing Date").

                  ii. On the Closing Date, the Project shall be sold to Tenant
or its affiliate "AS IS","WHERE IS".

                  iii. On the Closing Date, Landlord will convey to Tenant, or
its affiliate, an assignment of all fixtures, machinery and personalty of every
description attached to or specifically used in connection with the Project,
including without limitation, all contract rights, guaranties and warranties of
any nature, all architects', engineers', surveyors' and other real estate
professionals' plans, specifications, certifications, contracts, reports, data
or other technical descriptions, reports or audits all without warranty as to
completeness or accuracy, all governmental permits, licenses, certificates, and
approvals in connection with the ownership of the Project, all instruments,
documents of title, general intangibles, and business records pertaining to the
Project, and all of Landlord's rights, claims, and causes of action if any, to
the extent they are assignable, under any warranties and/or guarantees of
manufacturers, contractors or installers, all rights against third parties
relating to the Project or the operation or maintenance thereof,

                  iv. Landlord shall execute an agreement on the Closing Date to
complete any remaining punchlist items within a reasonable time following the
Closing Date.

                  v. On the Closing Date, this Lease shall terminate and the
obligations of the parties hereunder shall cease. Tenant shall pay all
documentary stamp taxes, all title insurance premiums and other costs and
expenses payable in connection with the conveyance of the Project. Landlord and
Tenant shall split equally any realty transfer tax and recording fees for the
deed. All real estate and school taxes shall be apportioned to the Closing Date.
Rent shall be apportioned to the Closing Date, Landlord shall refund to Tenant
any prepaid rent and return the Security Deposit, and Tenant shall pay to
Landlord any sum owing to Landlord, whether owned pursuant to the terms hereof
or otherwise.

                  vi. On the Closing Date, Landlord shall convey the Project to
Tenant, or its affiliate (including any officer or director of Tenant), by
special warranty deed, free and clear of all liens and encumbrances excepting
however, (a) restrictions, conditions, easements, rights and agreements which
are of record or physically noticeable on the date Tenant exercises the Option
or which a survey would disclose on the date Tenant exercises the Option, (b)
liens for unpaid Taxes which Tenant is required to pay under this Lease; (c)
rights of governmental authorities and others arising in connection with
condemnation proceedings instituted after the date of Tenant's exercise of the
Option of which Tenant shall have been provided notice (d) any liens or
encumbrances created or approved by Tenant on or after the date of this Lease
(e) discrepancies or conflicts in boundary lines, easements, encroachments on
area content which a satisfactory survey would disclose and those created or
consented to by Tenant hereunder and (f) the easements and declaration
referenced in subsection (vi) below. Except as otherwise set forth above, the
title to the Project shall be good and marketable and such as will be insured
free and clear as aforesaid by any reputable title insurance company doing
business in the Philadelphia area.

                                       41
<PAGE>

                  vii. Landlord and Tenant shall execute (a) any and all
easement agreements reasonably required by Landlord in connection with its
development of its adjacent property (b) a declaration of covenants and
restrictions with such terms as Landlord shall deem reasonably necessary which
shall include, but are not limited to, signage rights, access and parking rights
and any other rights reasonably required for the use and enjoyment of Landlord's
adjacent property; provided that nothing therein shall interfere with Tenant's
Permitted Uses nor materially detract from the value of the Project and (c) any
other commercially reasonable document necessary to consummate the purchase as
set forth in this Article 41.

                  viii. Landlord and Tenant shall execute a commercially
reasonable agreement whereby Landlord shall be granted the exclusive rights to
market the Project for five years from the Closing Date in the event Tenant
determines to lease more than 10,000 square feet of space at the Project to
third parties.

            B. For a period of five years following the Closing Date, if Tenant
shall desire to sell the Project or shall receive a bona fide offer to purchase
the Project, which offer it proposes to accept, Tenant shall deliver or mail to
Landlord written notice of the same containing a legible photocopy or other
exact copy of such offer or the terms of such sale. Landlord shall have the
right and option to purchase the Project for the price and on the terms and
conditions no less favorable to Tenant than those set forth in the offer it has
received from Tenant or the terms upon which Tenant proposes to sell the
Project. Landlord shall notify Tenant of its election to purchase the Project in
writing within forty-five (45) days from and after the date Landlord received
written notice of the proposed sale from Tenant. In the event Landlord elects to
purchase the Project, section (A) of this Article 41 shall apply (except to the
extent the same is inconsistent with the terms of the offer accepted by
Landlord) and Tenant shall convey the Project to Landlord. In the event Landlord
elects not to purchase the Project but the sale to the third party is not
consummated for any reason whatsoever, the terms of this subsection (C) shall
apply to any subsequent offer received by Tenant for a period of five years from
the Closing Date.

            C. Tenant recognizes that the Project will be removed by Landlord
from the market after Tenant sends its Option Notice and that if this purchase
and sale is not consummated because of Tenant's default Landlord shall be
entitled to compensation for such detriment. Landlord and Tenant acknowledge
that it is extremely difficult and impracticable ascertain the extent of the
detriment, and to avoid this problem, Landlord and Tenant agree that if the
purchase and sale contemplated in this Article 41 is not consummated because of
Tenant's default under this Article 41, Landlord shall be entitled to retain the
Deposit as liquidated damages. The parties agree that the sum stated above as
liquidated damages shall be in lieu of all other relief to which Landlord might
otherwise be entitled, Landlord hereby specifically waiving any and all rights
which it may have to damages or specific performance as a result of Tenant's
default under this Article 41. The parties further acknowledge that the Lease
will remain in full force and effect if the purchase and sale is not consummated
for any reason.

                                       42
<PAGE>

            D. If Tenant fails to exercise this option within one hundred and
eighty days prior to the last day of the third month of the Term, such option
shall terminate and be of no further force or effect.

         42. RIGHT OF FIRST OFFER TO PURCHASE.

            If Landlord desires to offer the Project as defined in Article 1(b)
hereof for sale, then provided that an Event of Default, shall not have occurred
beyond any applicable cure period within the twelve month period prior thereto,
before entering into a negotiation, for the sale of the Project, and only the
Project, with any other party, Landlord shall give notice to Tenant of
Landlord's desire to sell the Project (a "Sale Notice"), stating therein the
essential terms of sale proposed by Landlord (the "Essential Terms"). If within
ten (10) days after Landlord's delivery of a Sale Notice or Second Sale Notice
as the case may be, Tenant gives Landlord notice of Tenant's desire to purchase
the Project on the Essential Terms, then Landlord and Tenant shall, reasonably
and in good faith, negotiate the terms of a mutually acceptable purchase and
sale agreement for the Project. Tenant's failure, within such ten (10) day
period, time being of the essence, to accept the terms set forth in the Sale
Notice or Second Sale Notice, as the case may be, shall constitute Tenant's
election to waive its right of first offer to purchase the Project. If within
fifteen (15) days after Landlord's delivery of the Sale Notice, Landlord and
Tenant have not executed and delivered a mutually acceptable purchase and sale
agreement or if Tenant shall be deemed to have waived its right of first offer,
Tenant shall have no further right with regard to the purchase of the Project
under the Essential Terms and Landlord shall be free to effect such sale of the
Project as Landlord shall determine; provided, however, if Landlord proposes to
accept an offer with a purchase price less favorable to Landlord than the
Essential Terms, Landlord shall give Tenant a further sale notice ("Second Sale
Notice"), stating therein the new terms, and Tenant's right of first offer, on
the new terms specified by Landlord in such Second Sale Notice, shall again be
effective, subject again to the same notice requirements and time limitations as
are provided above in this Section. In the event either Tenant fails to respond
to the Second Sale Notice within the requisite time period or Landlord and
Tenant are unable to agree on a purchase and sale agreement within fifteen (15)
days, Tenant shall have no further right with regard to the purchase of the
Project and Landlord shall be free to effectuate a sale of the Project under any
terms.

            It is expressly agreed and understood that the rights set forth in
this Article shall not apply in the event the Project is included in the sale of
any other real estate holding(s) owned by Landlord or its affiliates.

                                       43
<PAGE>

            It is understood and agreed that the aforesaid right of first offer
to purchase is personal to the originally-named Tenant herein, or its affiliate
(including any officer or director of Tenant and any entity controlling,
controlled by or under common control with such Tenant which may receive an
assignment of this Lease in accordance with subsection 12(e) hereof) and is not
transferable under any circumstances, and shall apply (unless and until waived
as aforesaid, and not thereafter) only during the Term hereof, as the same may
have been extended, and only if no Event of Default shall have occurred beyond
any applicable cure period in the twelve month period prior thereto. It is
further understood and agreed that the aforesaid right of first offer to
purchase shall in no event be triggered by or be applicable to a sale or
transfer by Landlord to any party controlling, controlled by or under common
control with Landlord or in connection with any merger, reorganization or other
business combination of or involving Landlord.

            The parties expressly acknowledge and agree that the Broker (as
defined in subsection 1(k) hereof) shall not be entitled to receive any fee or
commission in connection with the consummation of any sale of the Project (or
part thereof) to Tenant.

            IN WITNESS WHEREOF, the parties hereto have executed this Lease the
day and year first above written.

                                LANDLORD:

                                   WORK LETTER

                             _____ Lindenhurst Road
                                       for
                                 ICT GROUP, INC.

         A. Landlord's Work. Landlord shall cause the Building to be constructed
in substantial accordance with the plans listed on Exhibit 1 hereto (the "Base
Building Work"), as amended by changes to such plans as required by Landlord
("Landlord's Plans"). Landlord's Plans shall depict, with regard to the
Premises, Landlord provided VAV system(s), primary ducts, fire stairways,
elevator lobbies, restrooms, mechanical rooms, and telephone and equipment
rooms. These items will be provided in accordance with applicable building
codes. There shall be a $150,000 allowance (which is not part of the Tenant
Allowance) for completion of the finishes to the Building lobby.

         Tenant will be required to cause its architect to coordinate Tenant's
interior design documentation with Landlord's Base Building Work. Tenant
acknowledges receipt of Landlord's Plans on and as of the date of the Lease.

         Landlord shall have the right, from time to time, to make changes to
Landlord's Plans; provided however, in the instance of any material revision or
supplement to Landlord's Plans which would require a material change in or
result in a material increase in the cost of Tenant Work (as hereinafter
defined), then such revisions and supplements shall be submitted to Tenant for
approval, which approval shall not be unreasonably withheld, delayed or
conditioned. Tenant's failure to approve such changes or to disapprove such
changes with specific comment within ten (10) days next following notice thereof
from Landlord shall for all purposes constitute Tenant's deemed approval of the
revision or supplement to be implemented by Landlord. Landlord shall further
share all revised plans with Tenant's architect.

         Landlord shall provide drywall on the "tenant space side" of core
walls, around columns (column covers) and all exterior building walls from the
floor to the base of all windows. Landlord shall also provide window sills as
part of Landlord's Work. Window coverings, as depicted in the Base Building
Work, or as otherwise selected by Landlord and approved by Tenant within (5)
days next following Landlord's request therefor (Tenant's failure to approve or
to disapprove with specific comments, within such time frame, shall for all
purposes constitute Tenant's deemed approval of Landlord's selection), will be
provided by Landlord at each perimeter window at Landlord's cost.

         Within ten (10) days after receipt of Landlord's Plans, Tenant shall
submit to Landlord for its approval detailed engineered plans and
specifications, together with such additional information as Landlord may
require regarding proposed structural (e.g. floor loading and beam penetrations)

<PAGE>

and mechanical/electrical/plumbing (e.g. kitchen and computer room)
modifications to Landlord's Plans which are necessary to accommodate Tenant
Plans (as hereinafter defined). If Tenant's detailed engineered plans and
specifications and such additional information as Landlord shall require shall
be delivered as and when hereinabove specified (a Tenant Delay (as hereinafter
defined) shall result to the extent that Tenant shall take more than ten (10)
days in providing same following Landlord's submission of Landlord's Plans),
then any required modifications to Landlord's Plans, if approved by Landlord,
shall be incorporated into Landlord's Plans and constructed, all at Tenant's
cost.

         The work called for by Landlord's Plans ("Landlord's Work") shall be
deemed "substantially complete" when (i) the Building's ground floor lobby, and
public areas on the ground floor necessary for the Tenant's occupancy, have been
substantially completed as required by applicable code, (ii) to the extent
required to serve the Premises and the public areas necessary for Tenant's use
and enjoyment of the Premises, the heating, ventilating and air conditioning,
elevator and utility systems, including telephone trunk lines into the Building
(but not including installation of telephones, computers, or security systems
for the Premises), are installed and operating, (iii) the Building is weather
tight and roofing installed, (iv) subject to Section F below (in regard to the
issuance of certificates of occupancy where Landlord is not performing Tenant
Work, in which event securing all required certificates of occupancy for the
Premises shall be Tenant's responsibility), Landlord shall have obtained at
least a temporary certificate of occupancy for the Building and the Premises,
and (v) Landlord's architect shall have issued a certificate of substantial
completion for Landlord's Work. The "Substantial Completion Date," as such term
is used herein or in the Lease, shall be the date upon which Landlord's Work
shall be substantially complete, provided, however that in the event of any
Tenant Delays or Change Order Delays, the "Substantial Completion Date" shall be
the date upon which Landlord would have achieved substantial completion but for
such Tenant Delays or Change Order Delays. In the event Building landscaping has
not been completed by the Substantial Completion Date, Landlord shall complete
such landscaping as soon as reasonably practicable taking into consideration
planting seasons. In the event Landlord is able to obtain only temporary
certificates of occupancy, Landlord agrees to obtain permanent certificates of
occupancy as soon as reasonably practicable; provided, however that to the
extent Landlord's inability to obtain either temporary or permanent certificates
of occupancy shall be attributable to deficiencies in work performed or
materials supplied by Tenant, its agents, employees or contractors, then Tenant
alone shall be and remain responsible, at its sole cost and expense, to cure any
and all such deficiencies. The certification of Landlord's architect that
Landlord's Work has been substantially completed shall be conclusive evidence of
such completion and of the occurrence of the Substantial Completion Date.

<PAGE>

         B. Tenant Work. On or before April 15, 2001, Tenant shall cause to be
prepared and sealed by an architect licensed in the Commonwealth of
Pennsylvania, and shall submit to Landlord for its approval, all plans and
specifications required for the leasehold improvements to be constructed within
the Premises ("Tenant Plans"). Tenant shall reasonably endeavor to use
Landlord's professionals to prepare the Tenant Plans. Any delay by Tenant in
delivering the Tenant Plans as and when required hereunder shall constitute a
Tenant Delay. Tenant Plans shall be sufficient so long as Tenant Plans (a) are
complete, finished and include detailed architectural, electrical, plumbing,
fire protection, HVAC and engineering drawings including all necessary
dimensions and specifications and all finish schedules; (b) are practicable and
consistent with Landlord's Plans, subject to standard construction industry
tolerances and subject to reasonable as-built field conditions not specified on
Landlord's Plans, (c) involve construction within the Premises only and do not
adversely affect or compromise any portion of the Building, and (d) do not
require any special materials or design or changes in or of the Building which
is not then already set forth in Landlord's Plans or in Landlord's judgement
cannot be accommodated without additional expense or delay. Tenant's submission
of Tenant Plans to Landlord shall be deemed approval thereof by Tenant. Such
submission shall contain one complete electronic media (CAD) copy (said CAD copy
to contain Premises plans only), four blue-line or black-line prints and one
reproducible copy of each page. Tenant shall be solely responsible for the
completeness and compliance of Tenant Plans with all applicable laws, codes and
regulations, including without implied limitation, ADA, and all state and
municipal permitting requirements. Landlord shall review Tenant Plans and
respond to Tenant within thirty (30) days after submission, and should Landlord
elect to have Tenant Plans reviewed by Landlord's architects and engineers,
Tenant shall bear the reasonable expense of such review. Review and approval of
Tenant Plans by Landlord (and its professionals, as aforesaid) shall in no
instance be deemed or constitute a representation, warranty or confirmation by
Landlord or by its professionals of any kind regarding the completeness of
Tenant Plans or conformance therewith with applicable laws, codes or
regulations, or permitting requirements, or with the requirements of Landlord's
Plans, or the adequacy of Tenant's specifications or design, but rather
Landlord's review (and review by Landlord's professionals) is for the protection
of Landlord only; provided, however, that Landlord shall use reasonable efforts
to advise Tenant if such review indicates that Tenant Plans violate or fail to
satisfy any requirements of Landlord's Work. If Tenant Plans are not sufficient,
as above set forth, Landlord shall notify Tenant of the insufficiency and Tenant
shall cause such insufficiency to be remedied and the remedy shall be
incorporated into Tenant Plans by Tenant at Tenant's expense and resubmitted to
Landlord, and the time involved in Tenant's revision and resubmission of Tenant
Plans shall constitute a Tenant Delay; it being further understood that the
foregoing shall not diminish the effect of any intervening Change Order Delay.
If Landlord determines that Tenant Plans are still not sufficient after
Landlord's review and Tenant's resubmission, then the approval process described
above will be repeated; provided, however, that Landlord agrees to review
Tenant's resubmission(s) as promptly as is reasonably practicable. Tenant shall
make no changes to Tenant Plans after Landlord's approval thereof without the
prior written consent of Landlord, which approval shall not be unreasonably
withheld, delayed or conditioned, and which changes shall be requested and
implemented, if at all, only in accordance with the procedures set forth below.
Any delay in substantial completion of the construction set forth on Tenant
Plans ("Tenant Work") or in Landlord's Work resulting from such changes or from
an election by Tenant to incorporate special materials or designs in Tenant

<PAGE>

Plans shall be deemed to be a Tenant Delay and shall have the consequences
herein set forth. Landlord shall notify Tenant as quickly as reasonably
practicable after receipt of any changes to Tenant Plans if Landlord anticipates
that the proposed changes will delay substantial completion of construction.

         C. Construction of Tenant Work.

         On or before the date which is forty-five (45) days next following
Landlord's approval of Tenant Plans as provided in Section B above, Landlord
shall obtain and deliver to Tenant a cost proposal for the construction of
Tenant Work from Landlord's Contractor (the "Tenant Cost Proposal"). Landlord
acknowledges that Tenant may, subject to the conditions set forth in Section F
below, seek cost proposals and solicit bids from other general contractors
pre-approved by Landlord, during such forty-five (45) day period. Tenant shall
have ten (10) days from its receipt of the Tenant Cost Proposal (the "Cost
Review Period") to review and approve in writing the Tenant Cost Proposal. Any
delay in Tenant's approval of the Tenant Cost Proposal beyond the Cost Review
Period shall constitute a Tenant Delay if Tenant ultimately selects Landlord's
Contractor to construct Tenant Work, or if Tenant selects another contractor but
Tenant's delay nonetheless resulted in a delay in the prosecution of Landlord's
Work. Upon completion of the Cost Review Period, Tenant shall notify Landlord
either that (i) Tenant elects to use Landlord's Contractor to construct Tenant
Work in accordance with the approved Tenant Cost Proposal or (ii) Tenant has
selected another general contractor approved by Landlord to perform such work,
in which event the terms and conditions of Section F below shall apply. In the
event that Tenant elects to use Landlord's Contractor to construct Tenant Work,
then a Tenant Delay shall be deemed to have occurred from the expiration of the
initial Cost Review Period through the date upon which Tenant notifies Landlord
that Tenant has selected Landlord's Contractor to construct Tenant Work.

         If Tenant shall approve the Tenant Cost Proposal as and when herein
provided, Landlord shall contract with Landlord's Contractor for the
construction of the Tenant Work in accordance with the Tenant Cost Proposal, and
Landlord will administer such construction, without additional charge by
Landlord for Landlord's administration services, other than Landlord's out of
pocket fees, costs and expenses. Landlord shall endeavor to cause Landlord's
Contractor to reasonably consult with Tenant in the selection by Landlord's
Contractor of subcontractors for Tenant Work; provided, however, that Landlord's
Contractor shall at all times retain the right to make the final selection of
which subcontractors shall be engaged for the Tenant Work project.

         Tenant covenants and agrees to pay within ten (10) days next following
invoicing (and in any event, prior to and as a condition of taking occupancy),
for all costs and expenses associated with Tenant Work in excess of the Tenant
Allowance. If Landlord's Contractor shall request assurance of Tenant's
agreement to timely pay such excess amounts, Tenant shall provide Landlord's
Contractor with an agreement in writing assuring such payment. Any amounts not
paid by Tenant within ten (10) days next following invoicing shall accrue
interest at the Default Rate (or at such higher lawful rate of interest as may
be specified in such invoice(s)) from the date due until the date paid in full
by Tenant.

<PAGE>

         If Tenant deems any changes, additions or alterations in the Tenant
Plans necessary or desirable, Tenant shall submit such proposed changes,
additions or alterations to Landlord in writing. As promptly as is reasonably
practicable upon receipt of such proposed changes, additions or alterations,
Landlord shall provide Tenant with the following: (i) the estimated cost to
Tenant, if any, of the proposed changes, additions or alterations, and (ii) an
estimate of the delay, if any, in the estimated Substantial Completion Date
which will result from the installation of the proposed changes, additions or
alterations. If Landlord reasonably anticipates any delay in the prosecution of
either or both Landlord's Work and Tenant Work during such time as Landlord is
evaluating Tenant's proposed changes, additions or alterations, or as a result
of Landlord's evaluation thereof, Landlord shall advise Tenant of the same, and
unless Tenant shall immediately instruct Landlord to disregard Tenant's request,
then any such period of delay encountered in Landlord's review of Tenant's
requested changes, additions or alterations shall (the remaining provisions of
this Work Letter notwithstanding), constitute a Tenant Delay, regardless of
whether Tenant and Landlord shall subsequently execute a written change order
implementing such changes, additions and alterations.

         Within two (2) days next following Landlord's request therefor after
Tenant shall have submitted to Landlord its request to make such proposed
changes, additions and alterations, Tenant shall provide to Landlord such
further information as may be requested by Landlord in its evaluation of
Tenant's request, and within two (2) days after receipt from Landlord of
Landlord's estimate of cost and estimate of delay (as provided at clauses (i)
and (ii) in the preceding paragraph), Tenant shall notify Landlord in writing
which, if any, of the proposed changes Landlord is authorized to make, and any
delay by Tenant in delivering such notice and executing a written change order
(to the extent Tenant determines to make such changes) within such period shall
constitute a Tenant Delay. Landlord shall not be bound to effect any such
changes in the absence of a change order signed by Landlord and by Tenant
confirming the foregoing cost and delay information. In the event Tenant shall
fail to provide to Landlord any additional information requested by Landlord in
its evaluation of any proposed changes, additions or alterations within the
aforesaid two (2) days, then the time interval between the end of such two (2)
days and the day on which Landlord actually receives such information shall be
deemed to be a further Tenant Delay.

         Anything herein contained to the contrary notwithstanding, the parties
acknowledge and agree that the process of reviewing change order requests is
time consuming and costly, regardless of whether the changes contemplated are
ultimately implemented. Landlord discourages Tenant from the practice of
requesting that Landlord consider immaterial or "frivolous" changes or that
Landlord price out and estimate the possible delay associated with a broad range
of possible changes, alterations and additions, and in each such instance Tenant
is strongly encouraged to narrow the scope of its proposal to a finite number of
"alternatives" acceptable to Tenant and therefore the time and expense
associated with Landlord's review of the same. Tenant is advised that excessive
use of the change order process will invariably result in additional Tenant
Delays.

<PAGE>

         Tenant Delays arising under Section C of this Work letter in regard to
proposed changes, additions or alterations in Tenant Work are sometimes herein
or in the Lease referred to as "Change Order Delays."

         D. Job Meetings. Representatives of Tenant and Tenant's architect shall
be permitted to attend all job meetings during the course of construction of
Landlord's Work and, if so elected by Tenant as hereinabove provided, the
Tenant's Work. Tenant's initial construction representative will be
[____________] (Telephone:[_________________] Facsimile: [______________];
e-mail: _______@__________.com).

         E. Possession and Commencement Date. Landlord shall endeavor to have
the Landlord's Work and, if timely elected by Tenant as hereinabove provided,
the Tenant Work substantially completed by the Targeted Date (as such term is
defined in the Lease); provided, however, that the Targeted Date shall, in
addition to extension for Tenant Delay and Change Order Delay, also be extended
for the additional time equal to the aggregate time lost by Landlord due to
strikes or other labor disputes not caused by Landlord, intervening governmental
restrictions, delay in obtaining governmental permits and approvals, scarcity of
labor or materials, war or other emergency, accidents, floods, fire or other
casualties, atypical adverse weather conditions, or any cause which is beyond
the reasonable control of Landlord ("Force Majeure Delay"). The Targeted Date
notwithstanding, in no event shall any Tenant Delay or any Change Order Delay in
any manner delay or postpone any obligation of Tenant to pay Fixed Rent or
Additional Rent as and when such obligation shall have otherwise accrued under
the Lease.

         If Tenant shall timely elect to have Landlord's Contractor construct
Tenant Work as hereinabove provided, then Landlord Work and Tenant Work shall be
deemed substantially complete (and the "Substantial Completion Date," as such
term is used in the Lease shall be deemed to have occurred) on the date on which
the Premises are (or would have been, but for any Tenant Delay or Change Order
Delay) ready for occupancy in accordance with Tenant Plans, and any remaining
work can reasonably be expected to be completed by Landlord's Contractor within
such additional period of time thereafter as shall be reasonable under the
circumstances, provided Landlord's contractor shall have undertaken such
remaining work and shall be diligently prosecuting the same to completion, in
any case without materially adversely affecting Tenant's ability to occupy and
utilize substantially all the Tenant's Premises for the Permitted Use, and
provided, further that Landlord has obtained at least a temporary certificate of
occupancy permitting Tenant to occupy Tenant's Premises and Tenant's architect
has issued a certificate of substantial completion. Any remaining work shall be
fully described by Tenant's architect on a punch list to be certified to
Landlord, Tenant and Landlord's contractor and shall indicate all remaining work
and, except as hereinafter provided, shall be the sole document controlling such
remaining work. Tenant's acceptance of the punch list shall be Tenant's
acknowledgment that the Tenant's Premises are substantially complete. Anything
herein or in the Lease contained to the contrary notwithstanding, if Tenant's
architect withholds either or both the aforesaid certificate of substantial
completion and certified punch list, or withholds any other certifications
required hereunder or under the Lease, and if in Landlord's reasonable opinion
there is no reasonable basis for such withholding, Landlord may have the
certification(s) made by its own architect; in which event, Landlord's

<PAGE>

architect's certification shall be conclusive evidence of the date of
substantial completion of Landlord's Work and Tenant Work, and the contents of
the punch list, if any.

         F. Tenant's Contractor Constructs Tenant Work. If Tenant shall not
elect to have Landlord's Contractor construct Tenant Work as hereinabove
provided, then excepting only that portion of Landlord's Work which involves
improvements outside of the Premises (which improvements Landlord shall
prosecute to completion with diligence), provided that safe access to the
Premises from the ground floor of the Building shall be available to Tenant and
its contractors, Landlord's Work within the Premises shall be deemed to be
substantially complete at such time as Landlord's Work has, in the sole
judgement of Landlord's architect, proceeded to the point where Tenant's
contractor (subject to, and without limitation of the remaining terms,
conditions, covenants and agreements stated herein, in the Lease and in the
remaining exhibits thereto) may take possession of the Premises for the
prosecution of Tenant Work without material interference from Landlord or
Landlord's contractors in the prosecution and completion of Landlord's Work, and
where any Landlord Work then remaining within the Premises can reasonably be
expected to be completed by Landlord's contractor within forty-five (45) days,
or within such additional period of time thereafter as shall be reasonable under
the circumstances (including, without limitation, any Landlord's Work which in
Landlord's reasonable estimation cannot or reasonably should not be completed
until such time as Tenant Work has been completed or has been prosecuted to a
certain stage of completion), provided Landlord's contractor shall have
undertaken such remaining work and shall be diligently prosecuting the same to
completion as aforesaid (the "Landlord Delivery Date"). If Tenant Work is not
constructed by Landlord's Contractor, then the Substantial Completion Date and
Tenant's obligation to commence paying Fixed Rent and Additional Rent pursuant
to the terms of the Lease, shall be deemed to occur upon the Landlord Delivery
Date. Any such remaining Landlord's Work shall be fully described by Tenant's
architect on a punch list to be certified to Landlord, Tenant and Landlord's
contractor and shall indicate all remaining Landlord's Work and, except as
hereinafter provided, shall be the sole document controlling such remaining
work. Tenant's acceptance of the punch list shall be Tenant's acknowledgment
that Landlord's Work is substantially complete and the Premises are ready for
possession by Tenant for Tenant's improvement thereof. If Tenant's architect
withholds such certification without providing reasonably explanation, and if in
Landlord's reasonable opinion there is no reasonable basis for such withholding,
Landlord may have the certification made by its architect; in which event,
Landlord's architect's certification shall be conclusive evidence of the
Landlord Delivery Date, and the contents of such punch list, if any.

         If Landlord shall not be selected by Tenant to have Landlord's
Contractor construct Tenant Work, then anything contained herein or in the Lease
to the contrary notwithstanding, it shall be Tenant's obligation to secure all
required certificates of occupancy in regard to the Premises, and Tenant shall
indemnify, defend and save and hold harmless Landlord of, from and against any
and all losses, costs, expenses (including, without limitation, reasonable
attorneys' fees and costs) fines, penalties and other liabilities incurred by
Landlord as a result of Tenant's failure so to do. Any additional item of work
within the definition of Landlord's Work and required as a condition of the
issuance of such certificate(s) of occupancy shall be performed by Landlord at
Landlord's expense. Any and all other work required as a condition of such

<PAGE>

issuance shall be performed by Tenant at Tenant's expense. Delivery of
possession of the Premises by Landlord to Tenant for the performance of Tenant
Work notwithstanding, Landlord shall have continuous access to the Premises
during the course of Tenant Work in order for Landlord to make improvements to
the Building and to complete the build out of other spaces in the Building, so
long as Landlord's entry thereon shall not unreasonably interfere with the
prosecution of Tenant's construction work therein.

         Landlord shall endeavor to provide Tenant with written notice at least
ten (10) days prior to the anticipated Landlord Delivery Date or the Substantial
Completion Date of Landlord's Work and Tenant Work (if Landlord shall be
selected by Tenant to have Landlord's Contractor construct Tenant Work). If
Landlord's Contractor shall be constructing Tenant Work, then Landlord shall,
subject to the conditions hereafter enumerated, allow Tenant, its authorized
agents, employees and contractors, reasonable access to the Premises for the
purpose of taking measurements and for the installation of certain Tenant
improvements such as telephones, systems furniture and fixtures, all subject to
adherence to Landlord's construction requirements. In addition, Landlord shall
provide Tenant with written notice at the appropriate point during construction
of Landlord's Work (as reasonably determined by Landlord) to permit Tenant
access to the first floor plenum and the Premises for installation and servicing
of voice and data communications wiring and equipment. Any entry by Tenant, its
agents, employees or contractors prior to the Substantial Completion Date of
Landlord's Work or Tenant Work, or the Landlord Delivery Date, as applicable,
shall be at Tenant's own risk, expense and responsibility, and shall be subject
to all of the requirements set forth elsewhere in this Work Letter, in the
Lease, and in the exhibits attached thereto, and to each and all of the
provisions which follow below. If Tenant's contractor shall be constructing
Tenant Work, then anything in this Work Letter or in the Lease contained to the
contrary notwithstanding, Tenant should not expect access to the Premises for
the performance of Tenant Work, or otherwise, prior to the Landlord Delivery
Date, unless Landlord shall determine to grant such access upon Tenant's request
therefor, which request may be granted or withheld by Landlord in Landlord's
sole and absolute discretion. If Landlord shall agree to grant such access prior
to the Landlord Delivery Date, then without limitation of such other conditions
as Landlord may specify, Tenant's access shall also be subject to each and all
of the following conditions as well:

             (i) Tenant shall have obtained Landlord's prior written approval of
Tenant Plans, or if Tenant shall desire to enter the Premises before the
Substantial Completion Date or the Landlord Delivery Date, Tenant shall have
obtained Landlord's prior written approval for the specific work it proposes to
perform, and shall furnish Landlord with reasonably detailed plans and
specifications therefor. All such work shall be promptly commenced and
thereafter prosecuted with due diligence. No such work shall be performed in
such manner or at such times as to cause any delay in connection with any work
being done by any of Landlord's contractors or subcontractors in the Premises or
in the Building generally; Landlord agreeing to notify Tenant of any such delay
promptly after Landlord learns of the same, and any such delay being deemed to
be a Tenant Delay hereunder. Prior to commencing any construction, renovations,
alterations, or any other work in the Premises, Tenant shall cause its general
contractor and all subcontractors to execute and file in the Prothonotary's
Office for Bucks County, Pennsylvania a waiver of the right to file mechanics'
liens against the Premises and the Project in a form approved by Landlord.

<PAGE>

Tenant shall indemnify, defend and save and hold harmless Landlord of, from and
against any and all loss, cost, expense (including, without limitation,
reasonable attorneys' fees and costs), damage or liability which are incurred by
or assessed or asserted against Landlord as a result of Tenant's failure to
obtain such approval.

             (ii) All Tenant Work performed by Tenant pursuant to this Work
Letter shall be performed by contractors and subcontractors approved by Landlord
and shall, except as hereinafter expressly provided, be completed at Tenant's
sole cost and expense. Each and all contractors shall comply with the
requirements of the Lease and this Work Letter. In performing Tenant Work,
Tenant shall comply with the following requirements:

         (a) In addition to, and not in lieu of the other policies of insurance
required by this Lease, at all times between the start and completion of Tenant
Work (such period is herein referred to as "Tenant's Construction Period"),
before any work is commenced or Tenant's contractors' materials or equipment are
moved into the Building or onto any part of the Project, Tenant shall deliver to
Landlord an original certificate of insurance evidencing Tenant's "All Risk"
Builder's Risk Insurance in the standard form for the Commonwealth of
Pennsylvania, and Tenant's general contractor and all subcontractors shall
deliver to Landlord certificates evidencing the following types of insurance
coverage in the following minimum amounts:

             (i) Worker's compensation coverage as required by law and employers
liability coverage, including without limitation bodily injury caused by disease
with a limit of $250,000.00 per employee;

             (ii) Comprehensive general liability policy to include, without
limitation, completed operations, property damage, independent contractor's and
personal injury coverage with limits in an amount of not less than $5,000,000.00
Combined Single Limit for Tenant's general contractor, and not less than
$2,000,000.00 Combined Single Limit (or such other limit as Landlord or its
lender shall reasonably specify) for all subcontractors; and

             (iii) Automobile liability coverage, with bodily injury limits of
at least $1,000,000.00 per accident.

         (b) Unless the Lease is terminated pursuant to the provisions otherwise
set forth therein, repair and/or reconstruction of all or any portion of Tenant
Work damaged or destroyed by any casualty occurring during Tenant's Construction
Period shall be commenced by Tenant as soon as possible after such casualty;
provided that if all or any portion of Landlord's Work is also damaged or
destroyed by such casualty, Landlord shall, subject to the provisions of Section
18 of the Lease, diligently repair or reconstruct Landlord's Work and thereafter
notify Tenant when repairs or reconstruction of Landlord's Work is substantially
completed and, within fifteen (15) days after receipt of such notice, Tenant
shall diligently pursue such repair and/or reconstruction to completion.

<PAGE>

         (c) Tenant shall obtain and pay for all necessary permits and shall pay
all other fees required by public authorities or utility companies with respect
to Tenant Work. All work shall be performed in conformity with (i) the final
approved Tenant Plans, (ii) all applicable codes and regulations of governmental
authorities having jurisdiction over the Building and the Premises, and (iii)
valid building permits and other authorizations from appropriate governmental
agencies, when required, which shall have been obtained at Tenant's sole
expense. Any work not acceptable to the appropriate governmental agencies shall
be promptly corrected or replaced at Tenant's expense.

         (d) Tenant shall maintain the Premises and the common areas of the
Building and the Project in a clean, safe and orderly condition during
construction, and shall regularly remove from the Premises and the Project all
debris created by or resulting from such construction, and repair any damage
caused by Tenant or Tenant's contractors, servants, agents or employees. Tenant
shall promptly remove all unused construction materials, equipment shipping
containers, packaging, debris and waste from the Building and the Project.
Tenant shall contain all construction materials, equipment, fixtures, shipping
containers and debris within the Premises. Public corridors, service corridors,
elevator lobbies, the main Building lobby, all parking areas and the exterior of
the Building and the Project shall at all times be clear of Tenant's (and its
contractor's) equipment, materials, refuse and debris.

         (e) To the end there shall be no labor disputes which would interfere
with any other construction occurring within the Building or in the operation
thereof, or any part thereof including, but not limited to, the Premises, Tenant
agrees to engage the services of only such contractors or subcontractors as will
work in harmony and without causing any labor dispute with each other, with
Landlord's employees, contractors and subcontractors of all others working in or
upon the Building or the Project or any part thereof, and Tenant shall require
its contractors and subcontractors to employ only such labor as will work in
harmony and without causing any labor disputes with each other, with Landlord's
employees, contractors and subcontractors and with the employees, contractors
and subcontractors and with all others working in or upon the Building or the
Project or any part thereof. Furthermore, only those contractors and
subcontractors as have been duly licensed by the authority having jurisdiction
over the appropriate profession and which have been approved in writing by
Landlord may perform any portion of Tenant Work for Tenant in or upon the
Premises. Landlord reserves the right at all times to remove or, at Landlord's
option, to require upon demand that Tenant remove from the worksite any
contractors or subcontractors who are disruptive to the worksite or who
otherwise fail to continuously observe the terms and conditions herein
enumerated.

         (f) At any time and from time to time during the performance of Tenant
Work, Landlord, Landlord's architect and/or Landlord's contractor may enter upon
the Premises and inspect the work being performed by Tenant. Tenant Work shall
be performed by Tenant in a first-class and workmanlike manner, with the
Premises constructed in accordance applicable codes and Landlord-approved Tenant
Plans, and shall incorporate only new materials and be in good and usable
condition at the date of completion.

<PAGE>

         (g) Tenant Work shall be coordinated by Tenant with all work being
performed or to be performed by Landlord, including, without limitation,
Landlord's Work, to the end that Tenant's prosecution of Tenant Work shall not
in any manner interfere with the operation of the Building or interfere with or
delay the completion of any other construction within the Building.

         (h) Except with regard to the "staging area," if any, as may be
identified by Landlord, neither Tenant nor its contractors or subcontractors may
use any space within the Building or the Project (except the Premises) for
storage, handling, and moving of materials and equipment, and if Tenant or such
contractors and/or subcontractor shall use any space in the Building or the
Project (except the Premises) for any of the aforesaid purposes without
obtaining Landlord's prior written approval thereof, Landlord shall have the
right to terminate such use and remove all of Tenant's and such contractor's or
subcontractor's material, equipment and other property from such space without
Landlord being liable to Tenant and/or such contractors or subcontractors and
the cost of such termination and/or removal shall be paid by Tenant to Landlord.
It shall be Tenant's responsibility to cause each contractor and subcontractor
to maintain continuous protection of adjacent property and improvements against
damage by reason of Tenant Work. If Landlord shall provide Tenant with any
exterior staging area, Tenant shall provide a secure chain link fence, at
appropriate height, surrounding the staging area and shall also provide
appropriate lighting for the staging area. Tenant shall, at Tenant's sole cost
and expense, repair any damage to the Building or the Project caused by Tenant's
establishment and use of the "staging area" and fencing of the premises,
including, but not limited to, repair of any damage to the parking areas caused
by the installation of fence(s) and the use of a construction dumpster.

             (i) Tenant shall promptly pay all contractors and materialmen so as
to minimize the possibility of a lien or claim of lien being filed with respect
to the Premises, the Building or the Project, and should any such lien be made
or filed, Tenant shall cause the same to be discharged by bond or otherwise
within ten (10) days (or within such shorter period as may be specified by
Landlord's lender) after written demand by Landlord. If Tenant shall fail to
cause such lien or claim of lien to be bonded against or to be discharged within
the period aforesaid, then in addition to any other right or remedy which
Landlord may have under the Lease, at law or in equity, Landlord may, but shall
not be obligated to, discharge the same either by paying the amount claimed to
be due or by procuring the discharge of such lien or claim of lien by deposit or
by bonding proceedings and, in any such event, Landlord shall be entitled, if
Landlord so elects to compel the prosecution of any action for the foreclosure
of such lien or claim of lien by the lienor with interest, costs and expenses.
Any amounts so paid by Landlord and all costs and expenses incurred by Landlord
in connection therewith or in connection with insuring the title to the Project
or any interest herein free of such lien or claim of lien, from the respective
dates of Landlord's making of the payment and incurring of the cost and expense,
shall constitute additional rent payable by Tenant under this Lease and shall be
paid by Tenant to Landlord on demand, and shall accrue interest thereon at the
Default Rate from the date incurred by Landlord until the date paid in full by
Tenant.

<PAGE>

             (ii) Nothing in this Work Letter shall be construed as in any way
constituting a consent or request by Landlord, expressed or implied, by
inference or otherwise, to any contractor, subcontractor, laborer, or
materialman for the performance of any labor or the furnishing of any materials
for any specific or general improvement, alteration, or repair of or to the
Premises or to any buildings or improvements thereon, or to any part thereof.
Notwithstanding anything in this Work Letter, or in any other writing signed by
Landlord to the contrary, neither this Work Letter nor any other writing signed
by Landlord shall be construed as evidencing, indicating, or causing an
appearance that any erection, construction, alteration or repair to be done, or
caused to be done, by Tenant is or was in fact for the immediate use and benefit
of Landlord.

             (iii) If Tenant shall construct Tenant Work as provided herein,
then the Tenant Allowance referenced in the Lease shall, the provisions of
Section 4(a) of the Lease notwithstanding, be paid and disbursed as follows.

         (a) Each draw request for the Tenant Allowance (each, a "Draw Request")
shall include Tenant's and Tenant's Architect's certification that the Tenant
Work covered thereby has been satisfactorily completed, shall be substantiated
by invoices for such work and such other materials and supporting documentation
as Landlord's lender shall reasonably specify, and shall be subject to such
lender's reasonable approval. Within thirty (30) days next following Landlord's
and its lender's receipt and approval of the final Draw Request (or within such
other period as Landlord's lender shall specify), Landlord shall make payment to
the Tenant's general contractor or as otherwise directed by Tenant, subject as
hereinafter provided.

         (b) Each Draw Request covering construction work shall be accompanied
by the AIA Application and Certificate for Payment (AIA Documents G702 and
G703), certified by Tenant's Architect, and covering only such work as is
actually installed in the Premises. All certificates for payment shall include
full releases of lien.

         (c) Landlord shall not disburse the final draw of the Tenant Allowance
until Landlord has received a final Draw Request accompanied by final lien
waivers and/or other evidence reasonably satisfactory to Landlord and Landlord's
lender that all contractors, workers, material and service suppliers and all
other persons having claims against Tenant for payment of work done or material
or services supplied in connection with the Tenant Work have been paid in full,
Landlord shall have received a final, sealed set of as-built plans for the
Premises from Tenant's Architect, final certificates of occupancy has been
issued by all relevant state and local authority(ies) and project manuals,
including all equipment warranties and guarantee, vendor listings with emergency
contacts and specification sheets for all major appliances.

         (d) All costs associated with Tenant Work in excess of the Tenant
Allowance shall be paid by Tenant within ten (10) days of receipt by Tenant of
invoices therefor. Any amounts not paid by Tenant within ten (10) days next
following invoicing shall accrue interest at the Default Rate (or at such higher
lawful rate of interest as may be specified in such invoice(s)) from the date
due until the date paid in full by Tenant.

<PAGE>

         G. Tenant Delay. Notwithstanding any provision herein or in the Lease
to the contrary, the Landlord Delivery Date for Landlord's Work and the
Substantial Completion Date for Landlord's Work and Tenant Work shall in no
event be delayed or extended by any "Tenant Delay" or Change Order Delay, and
each such date (as applicable) shall be deemed to have occurred on the day that
each such date (as applicable) would have occurred but for any intervening
Tenant Delay or Change Order Delay. Without limitation of the facts or
circumstances also agreed by the parties herein or in the Lease to constitute
"Tenant Delay," "Tenant Delay" shall also mean and include but not be limited to
delays resulting from changes, revisions or supplements to the scope of
Landlord's Work or Tenant Work requested by Tenant; Tenant's failure to provide
information, materials, documents, plans or specifications, or to furnish
Tenant's cooperation as required by Landlord in connection with Landlord's Work
or Tenant Work within the required time periods, including Tenant's initial
submission of Tenant Plans; delays in the preparation, finalization or approval
of the Tenant Plans caused by Tenant or its architect, contractors, authorized
representative, agents or employees; delays caused by modifications, revisions
or changes to Tenant Plans caused or required by Tenant or its architect,
contractors, authorized representative, agents or employees, or by any state or
municipal authority (including, without limitation, modifications, revisions or
changes required to Tenant Plans or Landlord's Plans upon presentation of Tenant
Plans (or revisions thereto) for permitting; delays in the delivery or
installation of any special, long-lead or non-standard items specified by
Tenant; or delays caused by delivery, installation or completion of any Tenant
finish work performed by Tenant's contractors; or any other delay caused by
Tenant or its architect, contractors, representatives, agents or employees.
Notwithstanding anything in this Section G to the contrary, with regard to those
Tenant Delays which, pursuant to the express provisions of this Work Letter,
shall not be assessed or be deemed to have occurred in the absence of Landlord's
notice, Landlord agrees to furnish such notice as soon as reasonably practicable
after Landlord shall have actual knowledge of the facts or circumstances giving
rise thereto; the parties agreeing that such notice may be delivered
telephonically or by facsimile transmission to Tenant's representative. In the
event any Tenant Delay or Change Order Delay shall occur, substantial completion
of the Landlord's Work and Tenant Work shall be deemed to have occurred on the
date on which substantial completion thereof would have occurred, but for the
Tenant Delays and Change Order Delays.
