<PAGE>
2.   PREMISES. Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord the Premises as shown on attached Exhibit "A" within the Building (the
Building and the lot on which it is located, the "PROPERTY"), together with the
non-exclusive right with Landlord and other occupants of the Building to use
all areas and facilities provided by Landlord for the use of all tenants in the
Property including any driveways, sidewalks and parking, loading and landscaped
areas (the "COMMON AREAS").

3.   ACCEPTANCE OF PREMISES. Tenant has examined and knows the condition of the
Property, the zoning, streets, sidewalks, parking areas, curbs and access ways
adjoining it, visible easements, any surface conditions and the present uses,
and Tenant accepts them in the condition in which they now are, without relying
on any representation, covenant or warranty by Landlord. Tenant and its agents
shall have the right, at Tenant's own risk, expense and responsibility, at all
reasonable times prior to the Commencement Date, to enter the Premises for the
purpose of taking measurements and installing its furnishings and equipment;
provided that the Premises are vacant and Tenant obtains Landlord's prior
written consent.

4.   USE; COMPLIANCE.

     (a)  PERMITTED USE. Tenant shall occupy and use the Premises for and only
for the Use specified in Section 1(f) above and in such a manner as is lawful,
reputable and will not create any nuisance or otherwise interfere with any
other tenant's normal operations or the management of the Building. Without
limiting the foregoing, such Use shall exclude any use that would cause the
Premises or the Property to be deemed a "place of public accommodation" under
the Americans with Disabilities Act (the "ADA") as further described in the
Building Rules (defined below). All Common Areas shall be subject to Landlord's
exclusive control and management at all times. Tenant shall not use or permit
the use of any portion of the Property for outdoor storage or installations
outside of the Premises nor for any use that would interfere with any other
person's use of any portion of the Property outside of the Premises.

     (b)  COMPLIANCE. Landlord represents that, as of the date of this lease,
there is no action required with respect to the Premises or Common Areas under
any laws (including Title III of the ADA), ordinances, notices, orders, rules,
regulations and requirements applicable to the Premises or to the Common Areas.
From and after the Commencement Date, Tenant shall comply promptly, at its sole
expense, (including making any alterations or improvements) with all laws
(including the ADA), ordinances, notices, orders, rules, regulations and
requirements regulating the Property during the Term which impose any duty upon
Landlord or Tenant with respect to Tenant's use, occupancy or alteration of, or
Tenant's installations in or upon, the Property including the Premises, (as the
same may be amended, the "LAWS AND REQUIREMENTS") and the building rules
attached as Exhibit "C", as amended by Landlord from time to time (the "BUILDING
RULES"). Provided, however, that Tenant shall not be required to comply with the
Laws and Requirements with respect to the footings, foundations, structural
steel columns and girders forming a part of the Property unless the need for
such compliance arises out of Tenant's use, occupancy or alteration of the
Property, or by any act or omission of Tenant or any employees, agents,
contractors, licensees or invitees ("AGENTS") of Tenant. With respect to
Tenant's obligations as to the Property, other than the Premises, at Landlord's
option and at Tenant's expense, Landlord may comply with any repair, replacement
or other construction requirements of the Laws and Requirements and Tenant shall
pay to Landlord all costs thereof as additional rent.

     (c)  ENVIRONMENTAL. Tenant shall comply, at its sole expense, with all
Laws and Requirements as set forth above, all manufacturers' instructions and
all requirements of insurers relating to the treatment, production, storage,
handling, transfer, processing, transporting, use, disposal and release of
hazardous substances, hazardous mixtures, chemicals, pollutants, petroleum
products, toxic or radioactive matter (the "RESTRICTED ACTIVITIES"). Tenant
shall deliver to Landlord copies of all Material Safety Data Sheets or other
written information prepared by manufacturers, importers or suppliers of any
chemical and ALL notices, filings, permits and any other written communications
from or to Tenant and any entity regulating any Restricted Activities.

     (d)  NOTICE. If at any time during or after the Term, Tenant becomes aware
of any inquiry, investigation or proceeding regarding the Restricted Activities
or becomes aware of any claims, actions or investigations regarding the ADA,
Tenant shall give Landlord written notice, within 5 days after first learning
thereof, providing all available information and copies of any notices.

5.   TERM. The Term of this lease shall commence on the Commencement Date and
shall end at 11:59 p.m. on the last day of the Term (the "EXPIRATION DATE"),
without the necessity for notice from either party, unless sooner terminated in
accordance with the terms hereof. At Landlord's request, Tenant shall confirm
the Commencement Date and Expiration Date by executing a lease commencement
certificate in the form attached as Exhibit "B".

6.   MINIMUM ANNUAL RENT. Tenant agrees to pay to Landlord the Minimum Annual
Rent in equal monthly installments in the amount set forth in Section 1(d) (as
increased at the beginning of each lease year as set forth in Section 1(d)), in
advance, on the first day of each calendar month during the Term, without
notice, demand or setoff, at Landlord's address designated at the beginning of

                                       2
<PAGE>
this lease unless Landlord designates otherwise; provided that rent for the
first full month shall be paid at the signing of this lease. If the
Commencement Date falls on a day other than the first day of a calendar month,
the rent shall be apportioned pro rata on a per diem basis for the period from
the Commencement Date until the first day of the following calendar month and
shall be paid on or before the Commencement Date. As used in this lease, the
term "LEASE YEAR" means the period from the Commencement Date through the
succeeding 12 full calendar months (including for the first lease year any
partial month from the Commencement Date until the first day of the first full
calendar month) and each successive 12 month period thereafter during the Term.

7. OPERATION OF PROPERTY; PAYMENT OF EXPENSES.

     (a) PAYMENT OF OPERATING EXPENSES. Tenant shall pay to Landlord the Annual
Operating Expenses in equal monthly installments in the amount set forth in
Section 1(d) (prorated for any partial month), from the Commencement Date and
continuing throughout the Term on the first day of each calendar month during
the Term, as additional rent, without notice, demand or setoff, provided that
the monthly installment for the first full month shall be paid at the signing
of this lease. Landlord shall apply such payments to the operating expenses
owed to Landlord by Tenant pursuant to the following Sections 7(b)-(f). The
amount of the Annual Operating Expenses set forth in Section 1(d) represents
Tenant's Proportionate Share of the estimated operating expenses during the
first calendar year of the Term on an annualized basis; from time to time
Landlord may adjust such estimated amount if the estimated operating expenses
increase. By April 30th of each year (and as soon as practical after the
expiration or termination of this lease or at any time in the event of a sale
of the Property), Landlord shall provide Tenant with a statement of the actual
amount of such expenses for the preceding calendar year or part thereof.
Landlord or Tenant shall pay to the other the amount of any deficiency or
overpayment then due from one to the other or, at Landlord's option, Landlord
may credit Tenant's account for any overpayment. Tenant's obligation to pay the
Annual Operating Expenses pursuant to this Section 7 shall survive the
expiration or termination of this lease.

     (b) TAXES AND OTHER IMPOSITIONS. Tenant shall pay prior to delinquency all
levies, taxes (including sales taxes and gross receipt taxes), assessments,
liens, license and permit fees, which are applicable to the Term, and which are
imposed by any authority or under any law, ordinance or regulation thereof, or
pursuant to any recorded covenants or agreements, and the reasonable cost of
contesting any of the foregoing (the "IMPOSITIONS") upon or with respect to the
Premises, or any improvements thereto, or directly upon this lease or the Rent
(defined in Section 7(f)) or amounts payable by any subtenants or other
occupants of the Premises, or against Landlord because of Landlord's estate or
interest herein. Additionally, Tenant shall pay as aforesaid its Proportionate
Share of any Imposition which is not imposed upon the Premises as a separate
entity but which is imposed upon all or part of the Property or upon the leases
or rents relating to the Property.

          (i) Nothing herein contained shall be interpreted as requiring Tenant
to pay any income, excess profits or corporate capital stock tax imposed or
assessed upon Landlord, unless such tax or any similar tax is levied or
assessed in lieu of all or any part of any Imposition or an increase in any
Imposition.

          (ii) If it shall not be lawful for Tenant to reimburse Landlord for
any of the Impositions, the Minimum Annual Rent shall be increased by the
amount of the portion of such Imposition allocable to Tenant, unless prohibited
by law.

     (c) INSURANCE.

          (i) PROPERTY. Landlord shall keep in effect, and Tenant shall pay to
Landlord its Proportionate Share of the cost of, insurance against loss or
damage to the Building or the Property by fire and such other casualties as may
be included within fire, extended coverage and special form insurance covering
the full replacement cost of the Building (but excluding coverage of Tenant's
personal property in, and any alterations by Tenant to, the Premises), and such
other insurance as Landlord may reasonably deem appropriate or as may be
required from time-to-time by any mortgagee.

          (ii) LIABILITY. Tenant, at its own expense, shall keep in effect
comprehensive general public liability insurance with respect to the Premises
and the Property, including contractual liability insurance, with such limits of
liability for bodily injury (including death) and property damage as reasonably
may be required by Landlord from time-to-time, but not less than a combined
single limit of $1,000,000 per occurrence and a general aggregate limit of not
less than $3,000,000 (which aggregate limit shall apply separately to each of
Tenant's locations if more than the Premises); however, such limits shall not
limit the liability of Tenant hereunder. The policy of comprehensive general
public liability insurance also shall name Landlord and Landlord's agent as
insured parties with respect to the Premises, shall be written on an
"occurrence" basis and not on a "claims made" basis, shall provide that it is
primary with respect to any policies carried by Landlord and that any coverage
carried by Landlord shall be excess insurance, shall provide that it shall not
be cancelable or reduced without at least 30 days prior written notice to
Landlord and shall be issued in form satisfactory to Landlord. The insurer shall
be a responsible insurance carrier which is authorized to issue such insurance
and licensed to do business in the state in which the Property is located and
which has at all times during the Term a rating of no less than A VII in the
most current edition of Best's Insurance Reports. Tenant shall deliver to
Landlord on or before the


                                       3
<PAGE>
Commencement Date, and subsequently renewals of, a certificate of insurance
evidencing such coverage and the waiver of subrogation described below.

          (iii)     WAIVER OF SUBROGATION. Landlord and Tenant shall have
included in their respective property insurance policies waivers of their
respective insurers' right of subrogation against the other party. If such a
waiver should be unobtainable or unenforceable, then such policies of insurance
shall state expressly that such policies shall not be invalidated if, before a
casualty, the insured waives the right of recovery against any party
responsible for a casualty covered by the policy.

          (iv)      INCREASE OF PREMIUMS. Tenant agrees not to do anything or
fail to do anything which will increase the cost of Landlord's insurance or
which will prevent Landlord from procuring policies (including public
liability) from companies and in a form satisfactory to Landlord. If any breach
of the preceding sentence by Tenant causes the rate of fire or other insurance
to be increase, tenant shall pay the amount of such increase as additional rent
promptly upon being billed.

     (d)  REPAIRS AND MAINTENANCE; COMMON AREAS; BUILDING MANAGEMENT. Except as
specifically otherwise provided in this Section (d), Tenant at its sole expense
shall maintain the Premises in good order and condition, promptly make all
repairs necessary to maintain such condition, and repair any damage to the
Premises caused by Tenant or its Agents. All repairs made by Tenant shall
utilize materials and equipment which are comparable to those originally used
in constructing the Building and Premises. When used in this Section (d), the
term "REPAIRS" shall include replacements and renewals when necessary.

          (i)       Landlord, at its sole expense, shall make all necessary
repairs to the footings, foundations, structural steel columns and girders
forming a part of the premises, provided that Landlord shall have no
responsibility to make any repair until Landlord receives written notice of the
need for such repair.

          (ii)      Landlord, at Tenant's sole expense, shall maintain and
repair the HVAC systems appurtenant to the Premises.

          (iii)     Landlord shall make all necessary repairs to the roof,
exterior portions of the premises and the Building, utility and communications
lines, equipment and facilities in the Building, which serve more than one
tenant, and to the Common Areas, the cost of which shall be an operating
expense of which Tenant shall pay its Proportionate Share, provided that
Landlord shall have no responsibility to make any repair until Landlord
receives written notice of the need for such repair. Landlord shall operate and
manage the Property and shall maintain all Common Areas and any paved areas
appurtenant to the Property in a clean and orderly condition. Landlord reserves
the right to make alterations to the Common Areas from time to time. Operating
expenses also shall include (A) all sums expended by Landlord for the
supervision, maintenance, repair, replacement and operation of the Common Areas
(including the costs of utility services), (B) any costs of building
improvements made by Landlord to the Property that are required by any
governmental authority or for the purpose of reducing operating expenses and
(C) a management and administrative fee applicable to the overall operation of
the Property.

          (iv)      Notwithstanding anything herein to the contrary, repairs
and replacements to the Property including the Premises made necessary by
Tenant's use, occupancy or alteration of, or Tenant's installation in or upon
the Property or by any act or omission of Tenant or its Agents shall be made at
the sole expense of Tenant to the extent not covered by any applicable
insurance proceeds paid to Landlord. Tenant shall not bear the expense of any
repairs or replacements to the Property arising out of or caused by any other
tenant's use, occupancy or alteration of, or any other tenant's installation in
or upon, the Property or by any act or omission of any other tenant or any
other tenant's Agents.

     (e)  UTILITY CHARGES. Tenant shall pay for water, sewer, gas, electricity,
heat, power, telephone and other communication services and any other utilities
supplied to or consumed in or on the Premises. Landlord shall not be
responsible or liable for any interruption in utility service, nor shall such
interruption affect the continuation or validity of this lease.

     (f)  NET LEASE. Except for the obligations of Landlord expressly set forth
herein, this lease is a "triple net lease" and Landlord shall receive the
Minimum Annual Rent as net income from the Premises, not diminished by any
expenses other than payments under any mortgages, and Landlord is not and shall
not be required to render any services of any kind to Tenant. The term "RENT"
as used in this lease means the Minimum Annual Rent, Annual Operating Expenses
and any other additional rent or sums payable by Tenant to Landlord pursuant to
this lease, all of which shall be deemed rent for purposes of Landlord's rights
and remedies with respect thereto. Tenant shall pay all Rent to Landlord within
30 days after Tenant is billed, unless otherwise provided in this lease, and
interest shall accrue on all sums due but unpaid.

8.   SIGNS. Except for signs which are located wholly within the interior of
the Premises and not visible from the exterior of the Premises, no signs shall
be placed on the Property without the prior written consent of Landlord.
All signs installed by Tenant shall

                                       4
<PAGE>
be maintained by Tenant in good condition and Tenant shall remove all such
signs at the termination of this lease and shall repair any damage caused by
such installation, existence or removal.

9.   ALTERATIONS AND FIXTURES.

     (a)  Subject to Section 10, Tenant shall have the right to install its
trade fixtures in the Premises, provided that no such installation or removal
thereof shall affect any structural portion of the Property nor any utility
lines, communications lines, equipment or facilities in the Building, serving
any tenant other than Tenant. At the expiration or termination of this lease
and at the option of Landlord or Tenant, Tenant shall remove such
installation(s) and, in the event of such removal, Tenant shall repair any
damage caused by such installation or removal; if Tenant, with Landlord's
written consent, elects not to remove such installation(s) at the expiration or
termination of this lease, all such installations shall remain on the Property
and become the property of Landlord without payment by Landlord.

     (b)  Except for non-structural changes which do not exceed $5000 in the
aggregate, Tenant shall not make or permit to be made any alterations to the
Premises without Landlord's prior written consent. Tenant shall pay the costs
of any required architectural/engineering reviews. In making any alterations,
(i) Tenant shall deliver to Landlord the plans, specifications and necessary
permits, together with certificates evidencing that Tenant's contractors and
subcontractors have adequate insurance coverage naming Landlord and Landlord's
agent as additional insureds, at least 10 days prior to commencement thereof,
(ii) such alterations shall not impair the structural strength of the Building
or any other improvements or reduce the value of the Property or affect any
utility lines, communications lines, equipment or facilities in the Building,
serving any tenant other than Tenant, (iii) Tenant shall comply with Section 10
and (iv) the occupants of the Building and of any adjoining property shall not
be disturbed thereby. All alterations to the Premises by Tenant shall be the
property of Tenant until the expiration or termination of this lease; at that
time all such alterations shall remain on the Property and become the property
of Landlord without payment by Landlord unless Landlord gives written notice to
Tenant to remove the same, in which event Tenant will remove such alterations
and repair any resulting damage. At Tenant's request prior to Tenant making any
alterations, Landlord shall notify Tenant in writing, whether Tenant is
required to remove such alterations at the expiration or termination of this
lease.

10.  MECHANICS' LIENS. Tenant shall pay promptly any contractors and materialmen
who supply labor, work or materials, to Tenant at the Property and shall take
all steps permitted by law in order to avoid the imposition of any mechanic's
lien upon all or any portion of the Property. Should any such lien or notice of
lien be filed for work performed for Tenant other than by Landlord, Tenant shall
bond against or discharge the same within 5 days after Tenant has notice that
the lien or claim is filed regardless of the validity of such lien or claim.
Nothing in this lease is intended to authorize Tenant to do or cause any work to
be done or materials to be supplied for the account of Landlord, all of the same
to be solely for Tenant's account and at Tenant's risk and expense. Throughout
this lease the term "MECHANIC'S LIEN" is used to include any lien, encumbrance
or charge levied or imposed upon all or any portion of, interest in or income
from the Property on account of any mechanic's, laborer's, materialman's or
construction lien or arising out of any debt or liability to or any claim of any
contractor, mechanic, supplier, materialman or laborer and shall include any
mechanic's notice of intention to file a lien given to Landlord or Tenant, any
stop order given to Landlord or Tenant, any notice of refusal to pay naming
Landlord or Tenant and any injunctive or equitable action brought by any person
claiming to be entitled to any mechanic's lien.

11.  LANDLORD'S RIGHT OF ENTRY. Tenant shall permit Landlord and its Agents to
enter the Premises at all reasonable times following reasonable notice (except
in the event of an emergency), for the purpose of inspection, maintenance or
making repairs, alterations or additions as well as to exhibit the Premises for
the purpose of sale or mortgage and, during the last 12 months of the Term, to
exhibit the Premises to any prospective tenant. Landlord will make reasonable
efforts not to inconvenience Tenant in exercising the foregoing rights, but
shall not be liable for any loss of occupation or quiet enjoyment thereby
occasioned.

12.  DAMAGE BY FIRE OR OTHER CASUALTY.

     (a)  If the Premises or Building shall be damaged or destroyed by fire or
other casualty, Tenant promptly shall notify Landlord and Landlord, subject to
the conditions set forth in this Section 12, shall repair such damage and
restore the Premises to substantially the same condition in which they were
immediately prior to such damage or destruction, but not including the repair,
restoration or replacement of the fixtures or alterations installed by Tenant.
Landlord shall notify Tenant in writing, within 30 days after the date of the
casualty, if Landlord anticipates that the restoration will take more than 180
days from the date of the casualty to complete; in such event, either Landlord
or Tenant may terminate this lease effective as of the date of casualty by
giving written notice to the other within 10 days after Landlord's notice.
Further, if a casualty occurs during the last 12 months of the Term or any
extension thereof, Landlord may cancel this lease unless Tenant has the right
to extend the Term for at least 3 more years and does so within 30 days after
the date of the casualty.

                                       5
<PAGE>
     (b)  Landlord shall maintain a 12 month rental coverage endorsement or
other comparable form of coverage as part of its fire, extended coverage and
special form insurance. Tenant will receive an abatement of its Minimum Annual
Rent and Annual Operating Expenses to the extent the Premises are rendered
untenantable as determined by the carrier providing the rental coverage
endorsement.

13.  CONDEMNATION.

     (a)  TERMINATION. If (i) all of the premises are taken by a condemnation
or otherwise for any public or quasi-public use, (ii) any part of the premises
is so taken and the remainder thereof is insufficient for the reasonable
operation of Tenant's business or (iii) any of the Property is so taken, and,
in Landlord's opinion, it would be impractical or the condemnation proceeds are
insufficient to restore the remainder of the Property, then this lease shall
terminate and all unaccrued obligations hereunder shall cease as of the day
before possession is taken by the condemnor.

     (b)  PARTIAL TAKING. If there is a condemnation and this lease has not
been terminated pursuant to this Section, (i) Landlord shall restore the
Building and the improvements which are a part of the Premises to a condition
and size as nearly comparable as reasonably possible to the condition and size
thereof immediately prior to the date upon which the condemnor took possession
and (ii) the obligations of Landlord and Tenant shall be unaffected by such
condemnation except that there shall be an equitable abatement of the Minimum
Annual Rent according to the rental value of the Premises before and after the
date upon which the condemnor took possession and/or the date Landlord
completes such restoration.

     (c)  AWARD. In the event of a condemnation affecting Tenant, Tenant shall
have the right to make a claim against the condemnor for moving expenses and
business dislocation damages to the extent that such claim does not reduce the
sums otherwise payable by the condemnor to Landlord. Except as aforesaid and
except as set forth in (d) below, Tenant hereby assigns all claims against the
condemnor to Landlord.

     (d)  TEMPORARY TAKING. No temporary taking of the Premises shall terminate
this lease or give Tenant any right to any rental abatement. Such a temporary
taking will be treated as if Tenant had sublet the Premises to the condemnor and
had assigned the proceeds of the subletting to Landlord to be applied on account
of Tenant's obligations hereunder. Any award for such a temporary taking during
the Term shall be applied first, to Landlord's costs of collection and, second,
on account of sums owing by Tenant hereunder, and if such amounts applied on
account of sums owing by Tenant hereunder should exceed the entire amount owing
by Tenant for the remainder of the Term, the excess will be paid to Tenant.

14.  NON-ABATEMENT OF RENT. Except as otherwise expressly provided as to damage
by fire or other casualty in Section 12(b) and as to condemnation in Section
13(b), there shall be no abatement or reduction of the Rent for any cause
whatsoever, and this lease shall not terminate, and Tenant shall not be
entitled to surrender the Premises.

15.  INDEMNIFICATION OF LANDLORD. Subject to sections 7(c)(iii) and 16. Tenant
will protect, indemnify and hold harmless Landlord and its Agents from and
against any and all claims, actions, damages, liability and expense (including
fees of attorneys, investigators and experts) in connection with loss of life,
personal injury or damage to property in or about the Premises or arising out of
the occupancy or use of the Premises by Tenant or its Agents or occasioned
wholly or in part by any act or omission of Tenant or its Agents, whether prior
to, during or after the Term, except to the extent such loss, injury or damage
was caused by the negligence of Landlord or its Agents. In case any action or
proceeding is brought against Landlord and/or its Agents by reason of the
foregoing. Tenant, at its expense, shall resist and defend such action or
proceeding, or cause the same to be resisted and defended by counsel (reasonably
acceptable to Landlord and its Agents) designated by the insurer whose policy
covers such occurrence or by counsel designated by Tenant and approved by
Landlord and its Agents. Tenant's obligations pursuant to this Section 15 shall
survive the expiration or termination of this lease.

16.  WAIVER OF CLAIMS. Landlord and Tenant each hereby waives all claims for
recovery against the other for any loss or damage which may be inflicted upon
the property of such party even if such loss or damage shall be brought about
by the fault or negligence of the other party or its Agents; provided, however,
that such waiver by Landlord shall not be effective with respect to any
liability of Tenant described in sections 4(c) and 7(d)(iv).

17.  QUIET ENJOYMENT. Landlord covenants that Tenant, upon performing all of
its covenants, agreements and conditions of this lease, shall have quiet and
peaceful possession of the Premises as against anyone claiming by or through
Landlord, subject, however, to the exceptions, reservations and conditions of
this lease.

18.  ASSIGNMENT AND SUBLETTING.

     (a) LIMITATION. Tenant shall not transfer this lease, voluntarily or by
operation of law, without the prior written consent of Landlord which shall not
be withheld unreasonably. However, Landlord's consent shall not be required in
the event of any transfer by Tenant to an affiliate of Tenant which is at least
as creditworthy as Tenant as of the date of this lease and provided Tenant
delivers to Landlord the instrument described in Section (c)(iii) below,
together with a certification of such creditworthiness by Tenant and such
affiliate. Any transfer not in conformity with this Section 18 shall be void at
the option of Landlord, and Landlord may exercise any or all of its rights under
Section 23. A consent to one transfer shall not be deemed to be a consent to any
subsequent transfer. "Transfer" shall include any sublease, assignment, license
or concession agreement, change in ownership or control of Tenant, mortgage or
hypothecation of this lease or Tenant's interest therein or in all or a portion
of the Premises.

     (b) OFFER TO LANDLORD. Tenant acknowledges that the terms of this lease,
including the Minimum Annual Rent, have been based on the understanding that
Tenant physically shall occupy the Premises for the entire Term. Therefore, upon
Tenant's request to transfer all or a portion of the Premises, at the option of
Landlord, Tenant and Landlord shall execute an amendment to this lease removing
such space from the Premises, Tenant shall be relieved of any liability with
respect to such space and Landlord shall have the right to lease such space to
any party, including Tenant's proposed transferee.

     (c) CONDITIONS. Notwithstanding the above, the following shall apply to any
transfer, with or without Landlord's consent:

          (i) As of the date of any transfer, Tenant shall not be in default
under this lease nor shall any act or omission have occurred which would
constitute a default with the giving of notice and/or the passage of time.

          (ii) No transfer shall relieve Tenant of its obligation to pay the
Rent and to perform all its other obligations hereunder. The acceptance of Rent
by Landlord from any person shall not be deemed to be a waiver by Landlord of
any provision of this lease or to be a consent to any transfer.

          (iii) Each transfer shall be by a written instrument in form and
substance satisfactory to Landlord which shall (A) include an assumption of
liability by any transferee of all Tenant's obligations and the transferee's
ratification of and agreement to be bound by all the provisions of this lease,
(B) afford Landlord the right of direct action against the transferee pursuant
to the same remedies as are available to Landlord against Tenant and (C) be
executed by Tenant and the transferee.

          (iv) Tenant shall pay, within 10 days of receipt of an invoice which
shall be no less than $250, Landlord's reasonable attorneys' fees and costs in
connection with the review, processing and documentation of any transfer for
which Landlord's consent is requested.

19. SUBORDINATION; MORTGAGEE'S RIGHTS.

     (a) This lease shall be subordinate to any first mortgage or other primary
encumbrance now or hereafter affecting the Premises. Although the subordination
is self-operative, within 10 days after written request, Tenant shall execute
and deliver any further instruments confirming such subordination of this lease
and any further instruments of attornment that may be desired by any such
mortgagee or Landlord. However, any mortgagee may at any time subordinate its
mortgage to this lease, without Tenant's consent, by giving written notice to
Tenant, and thereupon this lease shall be deemed prior to such mortgage without
regard to their respective dates of execution and delivery; provided, however,
that such subordination shall not affect any mortgagee's right to condemnation
awards, casualty insurance proceeds, intervening liens or any right which shall
arise between the recording of such mortgage and the execution of this lease.

     (b) It is understood and agreed that any mortgagee shall not be liable to
Tenant for any funds paid by Tenant to Landlord unless such funds actually have
been transferred to such mortgage by Landlord.

     (c) Notwithstanding the provisions of Sections 12 and 13 above, Landlord's
obligation to restore the Premises after a casualty or condemnation shall be
subject to the consent and prior rights of Landlord's first mortgagee.

20.  RECORDING; TENANT'S CERTIFICATE. Tenant shall not record this lease or a
memorandum thereof without Landlord's prior written consent. Within 10 days
after Landlord's written request from time to time:

     (a) Tenant shall execute, acknowledge and deliver to Landlord a written
statement certifying the Commencement Date and Expiration Date of this lease,
that this lease is in full force and effect and has not been modified and
otherwise as set forth in the

                                       7
<PAGE>
form of estoppel certificate attached as Exhibit "D" or with such modifications
as may be necessary to reflect accurately the stated facts and/or such other
certifications as may be requested by a mortgage or purchaser. Tenant
understands that its failure to execute such documents may cause Landlord
serious financial damage by causing the failure of a financing or sale
transaction.

     (b)  Tenant shall furnish to Landlord, Landlord's mortgagee, prospective
mortgagee or purchaser reasonably requested financial information.

21.  SURRENDER: ABANDONED PROPERTY.

     (a)  Subject to the terms of Section 9(b), 12(a) and 13(b), at the
expiration or termination of this lease, Tenant promptly shall yield up in the
same condition, order and repair in which they are required to be kept
throughout the Term, the Premises and all improvements thereto, and all fixtures
and equipment servicing the Building, ordinary wear and tear excepted.

     (b)  Upon or prior to the expiration or termination of this lease, Tenant
shall remove any personal property from the Property. Any personal property
remaining thereafter shall be deemed conclusively to have been abandoned, and
Landlord, at Tenant's expense, may remove, store, sell or otherwise dispose of
such property in such manner as Landlord may see fit and/or Landlord may retain
such property as its property. If any part thereof shall be sold, then Landlord
may receive and retain the proceeds of such sale and apply the same, at its
option, against the expenses of the sale, the cost of moving and storage and any
Rent due under this lease.

     (c)  If Tenant, or any person claiming through Tenant, shall continue to
occupy the Premises after the expiration or termination of this lease or any
renewal thereof, such occupancy shall be deemed to be under a month-to-month
tenancy under the same terms and conditions set forth in this lease, except that
the monthly installment of the Minimum Annual Rent during such continued
occupancy shall be double the amount applicable to the last month of the Term.
Anything to the contrary notwithstanding, any holding over by Tenant without
Landlord's prior written consent shall constitute a default hereunder and shall
be subject to all the remedies available to Landlord.

22.  CURING TENANT'S DEFAULTS. If Tenant shall be in default in the performance
of any of its obligations hereunder, Landlord, without any obligation to do so,
in addition to any other rights it may have in law or equity, may elect to cure
such default on behalf of Tenant after written notice (except in the case of
emergency) to Tenant. Tenant shall reimburse Landlord upon demand for any sums
paid or costs incurred by Landlord in curing such default, including interest
thereon from the respective dates of Landlord's incurring such costs, which
sums and costs together with interest shall be deemed additional rent.

23.  DEFAULTS - REMEDIES

     (a)  DEFAULTS. It shall be an event of default:

          (i)   If Tenant does not pay in full when due any and all Rent;

          (ii)  If Tenant fails to observe and perform or otherwise breaches
any other provision of this lease;

          (iii) If Tenant abandons the Premises, which shall be conclusively
presumed if the Premises remain unoccupied for more than 10 consecutive days, or
removes or attempts to remove Tenant's goods or property other than in the
ordinary course of business;

          (iv)  If Tenant becomes insolvent or bankrupt in any sense or makes a
general assignment for the benefit of creditors or offers a settlement to
creditors, or if a petition in bankruptcy or for reorganization or for an
arrangement with creditors under any federal or state law if filed by or against
Tenant, or a bill in equity or other proceeding for the appointment of a
receiver for any of Tenant's assets is commenced, or if any of the real or
personal property of Tenant shall be levied upon; provided, however, that any
proceeding brought by anyone other than Landlord or Tenant under any bankruptcy,
insolvency, receivership or similar law shall not constitute a default until
such proceeding has continued unstayed for more than 60 consecutive days.

     (b)  REMEDIES. Then, and in any such event, Landlord shall have the
          following rights:

          (i)   To charge a late payment fee equal to the greater of $100 or 5%
of any amount owed to Landlord pursuant to this lease which is not paid within 5
days after the due date.

          (ii)  To enter and repossess the Premises, by breaking open locked
doors if necessary, and remove all persons and all or any property therefrom, by
action at law or otherwise, without being liable for prosecution or damages
therefor, and Landlord may,

                                       8
<PAGE>
at Landlord's option, make alterations and repairs in order to relet the
Premises and relet all or any part(s) of the Premises for Tenant's account.
Tenant agrees to pay to Landlord on demand any deficiency that may arise by
reason of such reletting. In the event of reletting without termination of this
lease, Landlord may at any time thereafter elect to terminate this lease for
such previous breach.

          (iii) To accelerate the whole or any part of the Rent for the balance
of the Term, and declare the same to be immediately due and payable.

          (iv)  To terminate this lease and the Term without any right on the
part of Tenant to save the forfeiture by payment of any sum due or by other
performance of any condition, term or covenant broken.

     (c)  GRACE PERIOD.  Notwithstanding anything hereinabove stated, neither
party will exercise any available right because of any default of the other,
except those remedies contained in subsection (b)(i) of this Section, unless
such party shall have first given 10 days written notice thereof to the
defaulting party, and the defaulting party shall have failed to cure the default
within such period; provided, however, that:

          (i)   No such notice shall be required if Tenant fails to comply with
the provisions of Sections 10 or 20(a), in the case of emergency as set forth in
Section 22 or in the event of any default enumerated in subsections (a)(iii) and
(iv) of this Section.

          (ii)  Landlord shall not be required to give such 10 days notice more
than 2 times during any 12 month period.

          (iii) If the default consists of something other than the failure to
pay money which cannot reasonably be cured within 10 days, neither party will
exercise any right if the defaulting party begins to cure the default within 10
days and continues actively and diligently in good faith to completely cure said
default.

          (iv)  Tenant agrees that any notice given by Landlord pursuant to this
Section which is served in compliance with Section 27 shall be adequate notice
for the purpose of Landlord's exercise of any available remedies.

     (d)  NON-WAIVER: NON-EXCLUSIVE.  No waiver by Landlord of any breach by
Tenant shall be a waiver of any subsequent breach, nor shall any forbearance by
Landlord to seek a remedy for any breach by Tenant be a waiver by Landlord of
any rights and remedies with respect to such or any subsequent breach. Efforts
by Landlord to mitigate the damages caused by Tenant's default shall not
constitute a waiver of Landlord's right to recover damages hereunder. No right
or remedy herein conferred upon or reserved to Landlord is intended to be
exclusive of any other right or remedy provided herein or by law, but each shall
be cumulative and in addition to every other right or remedy given herein or now
or hereafter existing at law or in equity. No payment by Tenant or receipt or
acceptance by Landlord of a lesser amount than the total amount due Landlord
under this lease shall be deemed to be other than on account, nor shall any
endorsement or statement on any check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of Rent due, or Landlord's right to
pursue any other available remedy.

     (e)  COSTS AND ATTORNEYS' FEES.  If either party commences an action
against the other party arising out of or in connection with this lease, the
prevailing party shall be entitled to have and recover from the losing party
attorneys' fees, costs of suit, investigation expenses and discovery costs,
including costs of appeal.

24.  REPRESENTATIONS OF TENANT.  Tenant represents to Landlord and agrees that:

     (a) The word "TENANT" as used herein includes the Tenant named above as
well as its successors and assigns, each of which shall be under the same
obligations and liabilities and each of which shall have the same rights,
privileges and powers as it would have possessed had it originally signed this
lease as Tenant. Each and every of the persons named above as Tenant shall be
bound jointly and severally by the terms, covenants and agreements contained
herein. However, no such rights, privileges or powers shall inure to the benefit
of any assignee of Tenant immediate or remote, unless Tenant has complied with
the terms of Section 18 and the assignment to such assignee is permitted or has
been approved in writing by Landlord. Any notice required or permitted by the
terms of this lease may be given by or to any one of the persons named above as
Tenant, and shall have the same force and effect as if given by or to all
thereof.

     (b) If Tenant is a corporation, partnership or any other form of business
association or entity, Tenant is duly formed and in good standing, and has full
corporate or partnership power and authority, as the case may be, to enter into
this lease and has taken all corporate or partnership action, as the case may
be, necessary to carry out the transaction contemplated herein, so that when
executed, this lease constitutes a valid and binding obligation enforceable in
accordance with its terms. Tenant shall provide


                                       9
<PAGE>
Landlord with corporate resolutions or other proof in a form acceptable to
Landlord, authorizing the execution of this lease at the time of such
execution.

25.  LIABILITY OF LANDLORD. The word "Landlord" as used herein includes the
Landlord named above as well as its successors and assigns, each of which shall
have the same rights, remedies, powers, authorities and privileges as it would
have had it originally signed this lease as Landlord. Any such person or
entity, whether or not named herein, shall have no liability hereunder after it
ceases to hold title to the Premises except for obligations already accrued
(and, as to any unapplied portion of Tenant's Security Deposit, Landlord shall
be relieved of all liability therefor upon transfer of such portion to its
successor in interest) and Tenant shall look solely to Landlord's successor in
interest for the performance of the covenants and obligations of the Landlord
hereunder which thereafter shall accrue. Neither Landlord nor any principal of
Landlord nor any owner of the Property, whether disclosed or undisclosed, shall
have any personal liability with respect to any of the provisions of this lease
or the Premises, and if Landlord is in breach or default with respect to
Landlord's obligations  under this lease or otherwise, Tenant shall look
solely to the equity of Landlord in the Property for the satisfaction of
Tenant's claims. Notwithstanding the foregoing, no mortgagee or ground lessor
succeeding to the interest of Landlord hereunder (either in terms of ownership
or possessory rights) shall be (a) liable for any previous act or omission of a
prior landlord, (b) subject to any rental offsets or defenses against a prior
landlord or (c) bound by any amendment of this lease made without its written
consent, or by payment by Tenant of Minimum Annual Rent in advance in excess of
one monthly installment.

interest shall be at the highest rate permitted under law but not in excess of
15% per annum.

     (e)  SEVERABILITY; GOVERNING LAW.  If any provisions of this lease shall
be declared unenforceable in any respect, such unenforceability shall not
affect any other provision of this lease, and each such provision shall be
deemed to be modified, if possible, in such a manner as to render it
enforceable and to preserve to the extent possible the intent of the parties as
set forth herein. This lease shall be construed and enforced in accordance with
the laws of the state in which the Property is located.

     (f)  "MORTGAGE" AND "MORTGAGEE."  The word "MORTGAGE" as used herein
includes any lien or encumbrance on the Premises or the Property or on any part
of or interest in our appurtenance to any of the foregoing, including without
limitation any ground rent or ground lease if Landlord's interest is or becomes
a leasehold estate. The word "MORTGAGEE" as used herein includes the holder of
any mortgage, including any ground lessor if Landlord's interest is or becomes
a leasehold estate. Wherever any right is given to a mortgagee, that right may
be exercised on behalf of such mortgagee by any representative or servicing

person, a partnership, a corporation, an association and any other form of
business association or entity.

     (h)  PROPORTIONATE SHARE. At any time or times, upon request of Landlord
or of any tenant of the Building, the method for allocating Tenant's
Proportionate Share of any Impositions, cost, charge, rent, expense or payment
then or thereafter payable shall be redetermined by an independent qualified
expert. The cost of such redetermination shall be borne by the tenants of the
Building in

                                       10

<PAGE>
     (e)  SEVERABILITY; GOVERNING LAW.  If any provisions of this lease shall be
declared unenforceable in any respect, such unenforceability shall not affect
any other provision of this lease, and each such provision shall be deemed to be
modified, if possible, in such a manner as to render it enforceable and to
preserve to the extent possible the intent of the parties as set forth herein.
This lease shall be construed and enforced in accordance with the laws of the
state in which the Property is located.

     (f)  "MORTGAGE" AND "MORTGAGEE."  The word "mortgage" as used herein
includes any lien or encumbrance on the Premises or the Property or on any part
of or interest in or appurtenance to any of the foregoing, including without
limitation any ground rent or ground lease if Landlord's interest is or becomes
a leasehold estate. The word "mortgagee" as used herein includes the holder of
any mortgage, including any ground lessor if Landlord's interest is or becomes a
leasehold estate. Wherever any right is given to a mortgage, that right may be
exercised on behalf of such mortgagee by any representative or servicing agent
of such mortgagee.

     (g)  "PERSON."  The work "person" is used herein to include a natural
person, a partnership, a corporation, an association and any other form of
business association or entity.

27.  NOTICES.  Any notice or other communications under this lease shall be in
writing and addressed to Landlord or Tenant at their respective addresses
specified at the beginning of this lease, except that after the Commencement
Date Tenant's address shall be at the Premises, (or to such other address as
either may designate by notice to the other) with a copy to any mortgagee or
other party designated by Landlord. Each notice or other communication shall be
deemed given if sent by prepaid overnight delivery service or by certified mail,
return receipt requested, postage prepaid or in any other manner, with delivery
in any case evidenced by a receipt, and shall be deemed received on the day of
actual receipt by the intended recipient or on the business day delivery is
refused. The giving of notice by Landlord's attorneys, representatives and
agents under this Section shall be deemed to be the acts of Landlord; however,
the foregoing provisions governing the date on which a notice deemed to have
been received shall mean and refer to the date on which a party to this lease,
and not its counsel or other recipient to which a copy of the notice may be
sent, is deemed to have  received the notice.

28.  SECURITY DEPOSIT.  At the time of signing this lease, Tenant shall deposit
with Landlord the Security Deposit to be retained by Landlord as cash security
for the faithful performance and observance by Tenant of the provisions of this
lease. Tenant shall not be entitled to any interest whatever on the Security
Deposit. Landlord shall have the right to commingle the Security Deposit with
its other funds. Landlord may use the whole or any part of the Security Deposit

compensate Landlord for any loss or damage it may suffer by reason of Tenant's
default under this lease. If Landlord uses all or any portion of the Security

29.  PA ADDITIONAL REMEDIES.

     (a)  When this lease and the Term or any extension thereof shall have been
terminated on account of any default by Tenant or when the Term or any extension
thereof shall have expired, Tenant hereby authorizes an attorney of any court of
record of the Commonwealth of Pennsylvania to appear for Tenant and for anyone
claiming by, through or under Tenant and to confess judgement against all such
paries, and in favor of Landlord, ?? ejectment and for the recovery of
possession of the Premises, of which this lease or a true and correct copy
hereof shall be good and sufficient warrant. AFTER
THE ENTRY OF ANY SUCH JUDGEMENT A WRIT OF POSSESSION MAY BE ISSUED THEREON
WITHOUT FURTHER NOTICE TO TENANT AND WITHOUT A HEARING. If for any reason after
such action shall have been commenced it shall be determined and possession of
the Premises remain in or be restored to Tenant, Landlord shall have the right
for the same default and upon any subsequent default(s) or upon the termination
of this lease or Tenant's right of possession as herein set forth, to again
confess judgement as herein provided, for which this lease or a true and correct
copy hereof shall be good and sufficient warrant.

     (b)  If Tenant shall default in payment of the Rent due hereunder, Tenant
hereby authorizes any attorney of any court of record of the Commonwealth of
Pennsylvania to appear for Tenant and to confess judgement against Tenant, and
in favor of Landlord, for all sums due hereunder plus interest, costs and an
attorney's collection commission equal to the greater of 10% of all such sums or
$1,000, for which this lease or a true and correct copy hereof shall be good and
sufficient warrant. TENANT UNDERSTANDS THAT THE FOREGOING PERMITS LANDLORD TO
ENTER A JUDGEMENT AGAINST TENANT WITHOUT PRIOR NOTICE OR HEARING. ONCE SUCH
JUDGEMENT HAS BEEN ENTERED AGAINST TENANT, ONE OR MORE WRITS OF EXECUTION OR
WRITS OF GARNISHMENT MAY BE ISSUED THEREON WITHOUT FURTHER NOTICE TO TENANT AND
WITHOUT A HEARING, AND, PURSUANT TO SUCH WRITS, LANDLORD MAY CAUSE THE SHERIFF
OF THE COUNTY IN WHICH ANY PROPERTY OF TENANT IS LOCATED TO SEIZE TENANT'S
PROPERTY BY LEVY OR ATTACHMENT. IF THE JUDGEMENT AGAINST TENANT REMAINS UNPAID
AFTER SUCH LEVY OR ATTACHMENT, LANDLORD CAN CAUSE SUCH PROPERTY TO BE SOLD BY
THE SHERIFF EXECUTING THE WRITS, OR, IF SUCH PROPERTY CONSISTS OF A DEBT OWED TO
TENANT BY ANOTHER ENTITY, LANDLORD CAN CAUSE SUCH DEBT TO BE PAID DIRECTLY TO
LANDLORD IN AN AMOUNT UP TO BUT NOT TO EXCEED THE AMOUNT OF THE JUDGEMENT
OBTAINED BY LANDLORD AGAINST TENANT, PLUS THE COSTS OF THE EXECUTION. Such
authority shall not be exhausted by one exercise thereof, but judgement may be
confessed as foresaid from time to time as often as any of said rental and other
sums shall fall due or be in arrears, and such owners may be exercised as well
after the expiration of the initial term of this lease and during any extended
or renewal term of this lease and after the expiration of any extended or
renewal term of this lease.

     (c)  The warrants to confess judgement set forth above shall continue in
full force and effect and be unaffected by amendments to this lease or other
agreements between Landlord and Tenant even if any such amendments or other
agreements increase Tenant's obligations or expand the size of the Premises.
Tenant waives any procedural errors in connection with the entry of any such
judgement or in the issuance of any one or more writs of possession or execution
or garnishment thereon.

(d)  TENANT KNOWINGLY AND EXPRESSLY WAIVES (I) ANY RIGHT, INCLUDING, WITHOUT
LIMITATION, UNDER ANY APPLICABLE STATUTE, WHICH TENANT MAY HAVE OR RECEIVE A
NOTICE TO QUIT PRIOR TO LANDLORD COMMENCING AN ACTION FOR REPOSSESSION OF THE
PREMISES AND (II) ANY RIGHT WHICH TENANT MAY HAVE TO NOTICE AND TO HEARING
PRIOR TO A LEVY UPON OR ATTACHMENT OF TENANT'S PROPERTY OR THEREAFTER.

Premises on behalf of Tenant and its contractor(s), at Tenant's sole expense, in
accordance with the plans or the description of improvements attached as Exhibit
"A" and the specifications attached as Exhibit "F". Landlord shall consent to
the alterations Tenant intends to make to the Premises in accordance with the
Plans provided that Tenant complies with Sections 13 and 14 of this Lease and
the following conditions:

     (a)  Completion Walk Through by Landlord: In addition to the right of
Landlord and its Agents to inspect the Premises as set forth in Section 15 of
this Lease, Landlord and its Agents shall have the right to conduct a
walk-through inspection of the Premises as completed by Tenant.

     (b)  Warranties: Any warranties from Tenant's contractor(s) shall be for
the benefit of Landlord as well as Tenant and Tenant shall deliver such
warranties to Landlord upon receipt.

     (c)  Workmanship: All construction shall be done in a good and workmanlike
manner and shall comply at the time of completion with all laws and
requirements. Tenant acknowledges that Landlord, on behalf of Tenant, shall
complete the Tenant Improvements during normal working hours while Tenant is
occupying portions of the Premises. Tenant shall work with Landlord to complete
all Tenant Improvements in a timely fashion.

38. TENANT ALLOWANCE.

     (a)  Allowance Amount: Landlord agrees to provide Tenant with an allowance
equal to the lesser of the Tenant's Cost or Three Hundred Six Thousand Six
Hundred Seventy Five Dollars ($306,675.00) (the lesser of which shall
hereinafter be referred to as the "Tenant Allowance"). For purposes of this
section, the "Tenant's Cost" shall be the aggregate of all costs, expenses and
fees incurred by or on behalf of Tenant in connection with the improvements to
be made by Tenant to the Premises in accordance with the Plans that have been
approved by Landlord. The Tenant's Cost shall include without limitation (i) the
cost charged to Tenant by Tenant's general contractor and all subcontractors for
performing such construction and (ii) the cost to Landlord of performing
directly any portion of such construction.

     (b)  Landlord agrees to provide an additional allowance of up to Fifty Four
Thousand Five Hundred Twenty Dollars ($54,520.00) ("Excess Allowance") in
connection with the improvements subject to (i) review of Tenant's financial
statements and possible additional security required by Landlord and (ii) the
actual Excess Allowance used amortized over the length of the Lease at a cost of
Fifteen Percent (15%) which will then become an increase in Minimum Annual Rent.

     By way of example, should Tenant utilize $25,000.00 of Excess Allowance the
calculation shall be $25,000.00 (present value), 15% annual interest, six (6)
year term, additional Minimum Annual Rent of Six Thousand Three Hundred Forty
Three 50/100 Dollars ($6,343.50).

     (c)  Acceptance of Premises: As of the date of this Lease, Tenant has
examined and knows the condition of the Property, the zoning, streets,
sidewalks, parking areas, curbs and access ways adjoining it, visible easements,
any surface conditions and the present uses, and Tenant accepts them in the
condition in which they now are, without relying on any representation, covenant
or warranty by Landlord. Tenant and its agent shall have the right, at Tenant's
own risk, expense and responsibility, at all reasonable times prior to the
Commencement Date, to enter 300 Chesterfield Parkway for the purpose of taking
measurements and installing
<PAGE>
its furnishings and equipment; provided that Tenant obtains Landlord's prior
written consent. Landlord shall negotiate in good faith with the current tenant
of 300 Chesterfield Parkway for access for the purpose of taking measurements
and installing its furnishings and equipment, subject to the same qualifications
as provided above. If no such access can be arranged, Landlord will make
available any available building or leasehold plans and specifications to assist
Tenant in the design of improvements.

Landlord represents to Tenant that as of the Commencement Date, the following
Building systems will be in good working order and repair: electrical, plumbing,
and HVAC systems.

39.  RENEWAL OPTION.

Provided that Landlord has not given Tenant notice of default more than two (2)
times preceding the Expiration Date, that there then exists no event of default
by Tenant under this lease nor any event that with the giving of notice and/or
the passage of time would constitute a default, and that Tenant is the sole
occupant of the Premises, Tenant shall have the right and option to extend the
Term for one (1) additional period of five (5) years, exercisable by giving
Landlord prior written notice, at least twelve (12) months in advance of the
Expiration Date, of Tenant's election to extend the Term; it being agreed that
time is of the essence and that this option is personal to Tenant and is
non-transferable to any assignee or sublessee (regardless of whether any such
assignment or sublease was made with or without Landlord's consent) or other
party. Such extension shall be under the same terms and conditions as provided
in this lease except as follows:

     (a)  the additional period shall begin on the Expiration Date and
thereafter the Expiration Date shall be deemed to be extended by five years;

     (b)  all references to the Term in this lease shall be deemed to mean the
Term as extended pursuant to this Section;

     (c)  there shall be no further options to extend; and

     (d)       the Minimum Annual Rent payable by Tenant for the additional
          period shall be computed based upon the then "Fair Market Rental Rate"
          of the Premises, based upon the rental rate then being quoted for
          comparable office space in similar office buildings located in the
          Great Valley, Pennsylvania market area, taking into account among
          other factors rental rate, lease term, and tenant improvements offered
          to renewal tenants but in no event shall the new rent be less than the
          Minimum Annual Rent payable at the end of the immediately preceding
          Term of the Lease. Within one (1) month after Landlord receivers
          Tenant's notice of the exercise of this option, Landlord will notify
          Tenant to the "Fair Market Rental Rate" which shall be Landlord's good
          faith determination of the rental rate applicable at such time for
          office space in similar buildings located in the Malvern, Pennsylvania
          Market Area ("Landlord's Rental Notice"). If Tenant objects to the
          Fair Market Rental Rate as so established, Tenant may rescind its
          exercise of this option to extend term, providing Tenant gives notice
          of such recision to Landlord on or before two (2) weeks after Tenant
          receives Landlord's Rental Notice, time being of the essence. If
          Tenant so rescinds its exercise, Tenant's option to extend term shall
          be deemed both unexercised and extinguished. If Tenant does not so
          rescind its exercise, the term of this Lease shall be extended as
          provided before, with the Minimum Annual Rent applicable to such
          additional period being computed based upon the Fair Market Rental
          Rate as stated in the Landlord's Rental Notice.

40.  EXISTING LEASE OBLIGATION.

Notwithstanding anything to the contrary contained herein, Landlord and Tenant
acknowledge that the premises are currently leased by AmeriSource Corporation.
Landlord and AmeriSource are negotiating a Lease Termination Agreement for the
Premises under which the AmeriSource Lease would terminate on June 16, 2000. If
Landlord and AmeriSource do not execute a Lease Termination Agreement by April
15, 2000, or AmeriSource executes said Lease Termination Agreement by April 15,
2000, but does not vacate the Premises on or before June 16, 2000, Landlord
shall notify Tenant when the Premises will first become available for occupancy
("Occupancy Date") and take possession of the Premises should the Occupancy
Date be prior to August 31, 2000. If Landlord is unable to provide Tenant
possession prior to August 31, 2000, Tenant may terminate ("Termination
Option") this Agreement upon fifteen (15) days written notice to Landlord. This
Termination Option shall expire on August 31, 2000.

In the event this agreement is terminated, then neither party shall have any
further rights or obligations under this agreement.
