For and in consideration of the covenants contained in this Lease, and upon the
terms and conditions set forth in this Lease, Landlord and Tenant, intending to
be legally bound, agree as follows:

         1. DEFINITIONS. The definitions set forth in the preceding Preamble
shall apply to the same capitalized terms appearing in this Lease. Additional
definitions are contained in Section 39 and throughout this Lease.

         2. PREMISES. Landlord hereby demises and leases the Premises to Tenant
and Tenant hereby leases and takes the Premises from Landlord for the Term and
upon the terms, covenants, conditions, and provisions set forth in this Lease,
including the Preamble (this "Lease").

         3. COMPLETION OF PREMISES.

                  a. Prior to the Commencement Date and at its sole cost and
expense, Landlord shall cause to be performed in a good and workmanlike manner
and in compliance with applicable laws all design and construction work
necessary to add 150 additional parking spaces, related drive lanes and lighting
on the Property (collectively, the "Site Work"), all in compliance with
applicable law, including curbing and landscaping if required by applicable law,
and generally consistent with the site plan attached hereto as Exhibit G.

                  b. Except for the Site Work, the Premises shall be delivered
to Tenant on the Delivery Date in its "As-Is, Where-Is" condition and Landlord
shall have no obligation to construct or install any improvements on the
Premises or to remodel, renovate, recondition, alter or improve the Premises for
Tenant's use prior to the commencement of the Term, Landlord's sole additional
obligation being to fund the Improvement Allowance in accordance with the Work
Letter. Landlord makes no representation or warranty as to the condition of the
Premises. Tenant acknowledges that Tenant has inspected the Premises or has had
the Premises inspected by professional consultants retained by Tenant, Tenant is
familiar with the condition of the Premises, and the Premises are suitable for
Tenant's purposes, and the condition of the Premises is acceptable to Tenant.
Nothing in this paragraph shall diminish any representation or covenant of
Landlord contained elsewhere in this Lease, or excuse Landlord from the
performance of Landlord's obligations under this Lease.

         4. USE OF PREMISES. Landlord represents that the Premises is zoned I-1
Campus Industrial. Tenant shall use the Premises only for the Permitted Use.

         5. FIXED BASIC RENT. Commencing on the Commencement Date and throughout
the Term, Tenant shall pay annual fixed basic rent ("Fixed Basic Rent") in the
amounts set forth on Exhibit B, which amount shall be due without notice or
demand and without setoff or deduction, in equal monthly installments equal to
one-twelfth of the annual Fixed Basic Rent, in advance, on the first day of each
calendar month during the Term. All payments of Fixed Basic Rent shall be made
by wire transfer through an ACH member financial institution to an account
designated by Landlord from time to time. If the Commencement Date falls on a
day other than the first day of a calendar month, the Fixed Basic Rent shall be
due and payable for such month, apportioned on a per diem basis for the period
between the Commencement Date and the first day of the next first full calendar
month in the Term and such apportioned sum shall be paid on the

                                        1
<PAGE>

Commencement Date. On or before December 20, 2003, Tenant shall pay the
installment of Fixed Basic Rent attributable to the first full calendar month of
the Term for which a full monthly installment of Fixed Basic Rent is payable
hereunder.

         6. REAL ESTATE TAXES

                  a. "Real Estate Taxes" shall mean all taxes, liens, charges,
imposts and assessments of every kind and nature, ordinary or extraordinary,
foreseen or unforeseen, general or special, levied, assessed or imposed by any
governmental authority based on the assessed value of the Property, as well as
all fees or assessments payable on account of the Property being located in any
special services district. Notwithstanding the foregoing:

                           (i)      If at any time during the Term the present
system of ad valorem taxation of real property shall be changed or supplemented
so that in lieu of or in addition to the ad valorem tax on real property there
shall be assessed on Landlord or the Property any tax of any nature which is
imposed in whole or in part, in substitution for, or in lieu of any tax which
would otherwise constitute a Real Estate Tax, such tax shall be included within
the term "Real Estate Taxes," but only to the extent that the same is in lieu of
ad valorem real estate taxes and would be payable if the Property were the only
property of Landlord.

                           (ii)     If any special assessment is permitted to be
paid in installments over a period of time, Landlord shall elect the longest
available installment period and Tenant shall be responsible to pay only those
installments which fall within the Term.

                           (iii)    There shall be excluded from Real Estate
Taxes all excise, franchise, estate, succession and inheritance taxes, transfer
taxes imposed on any conveyance of the Property or any part thereof and, except
as otherwise provided in Subsection 6(a)(i) above, all income taxes and excess
profit taxes.

                  b. Payment. Commencing on the Commencement Date and throughout
the Term, Tenant shall pay all Real Estate Taxes for tax periods falling within
the Term. Except as provided below, all Real Estate Taxes shall be paid by
Tenant directly to the applicable taxing authority on or before the date by
which payment must be made in order to avoid the imposition of late payment fees
and penalties. Tenant shall not be obligated to take advantage of discount
periods. Real Estate Taxes for the tax periods in which the Commencement Date
and the termination date of the Term occur shall be paid by Landlord and
prorated, and Tenant shall pay to Landlord, within thirty (30) days after Tenant
receives from Landlord receipted tax bills showing the payment made by Landlord
and the period covered, the prorated portion applicable to the Term. Landlord
shall cooperate with Tenant's efforts to have all assessments and tax bills
mailed directly to Tenant at the Premises by the taxing authorities. If any
bills or assessments are sent to Landlord, Landlord shall forward them to Tenant
within five (5) days. Similarly, for the first and last Lease Year, if Tenant
received such bills or assessments it shall forward same to Landlord within
fifteen (15) days following receipt. Upon request by Landlord from time to time
throughout the Term, Tenant shall furnish to Landlord receipted bills or other
reasonable evidence that the Real Estate Taxes have been paid by Tenant.

                                      -2-
<PAGE>

                  c. Contest. Tenant shall have the exclusive right to contest
Real Estate Taxes and related assessments on the Premises during the Term. If
applicable law requires that a contest be brought in the name of the land owner,
Landlord will cooperate to enable Tenant to prosecute its contest, provided
however that all expenses of the contest shall be paid by Tenant. All refunds
and credits applicable to tax periods falling within the Term shall belong
solely to Tenant.

                  d. Tenant's Personalty. Tenant shall pay all taxes imposed
upon Tenant's furnishings, trade fixtures, equipment or other personal property.

         7. MANAGEMENT FEE. Commencing on the Commencement Date and throughout
the Term, Tenant shall pay to Landlord as Additional Rent an annual fee of Ten
Thousand Dollars ($10,000) for Landlord's services in connection with the
Premises as set forth in this Lease. The payment shall be made in twelve equal
monthly installments at the time and in the manner set forth in this Lease for
the payment of Fixed Basic Rent.

         8. INTEREST AND LATE CHARGE. At its option on written notice to Tenant,
Landlord may charge a late payment charge of three percent (3%) of any
installment of Fixed Basic Rent that is not paid within seven (7) days of the
due date thereof, provided, however that for the first occasion of late payment
in any Lease Year, neither the late charge nor Default Interest shall be charged
unless Tenant fails to pay the overdue installment within ten (10) days after
written notice of nonpayment from Landlord. Fixed Basic Rent due from Tenant to
Landlord which is not paid within thirty (30) days after the date due shall bear
interest at an interest rate (the "Default Rate") equal to the Prime Rate
published from time to time in the Money Rates column of the Wall Street Journal
plus 4% (or, if lower, the highest rate then allowed under the usury laws of the
Commonwealth of Pennsylvania) from the date due until the date paid. The right
of Landlord to charge a late charge and interest with respect to past due
installments of Fixed Basic Rent is in addition to Landlord's rights and
remedies upon an Event of Default.

         9. INSURANCE.

                  a. Tenant's Insurance. Tenant shall obtain, maintain and keep
in full force and effect the following insurance, at Tenant's sole cost and
expense, with companies authorized to do business in the Commonwealth of
Pennsylvania and having a rating of at least A+XV (or its equivalent) by Best
Rating Source or any successor thereto (or if there be none, an organization
having a national reputation in the field of rating property insurance
companies):

                           (i)      "All Risk" property insurance against fire,
theft, vandalism, malicious mischief, sprinkler leakage and such additional
perils as are now, or hereafter may be, included in a standard extended coverage
endorsement from time to time in general use in the Commonwealth of Pennsylvania
upon Tenant's equipment, furniture and furnishings, trade fixtures and other
personal property in the Building or otherwise on the Premises, in such amounts
and with such deductibles as Tenant deems appropriate.

                           (ii)     Workers' Compensation insurance in form and
amount as required by law.

                                      -3-
<PAGE>

                           (iii)    Commercial General Liability Insurance
coverage to include bodily injury, death, property damage and, where available
and customarily carried in Tenant's industry, operations hazard, contractual
liability, products and completed operations liability, naming Landlord as an
additional insured, in limits of not less than Three Million Dollars
($3,000,000), with commercially reasonable deductibles. Tenant shall furnish to
Landlord, no later than the Commencement Date and thereafter annually throughout
the Term, certificates addressed to Landlord as certificate holder, evidencing
the required liability insurance coverage, on the ACORD 27 form or comparable
form in which the insurer undertakes that the policy will not be cancelled
without 30 days notice to Landlord.

                           (iv)     Any other form or forms of insurance or any
increase in the limits of any of the aforesaid enumerated coverages or other
forms of insurance as Landlord or the mortgagees of Landlord may reasonably
require from time to time if in the reasonable opinion of Landlord or said
mortgagees said additional forms of insurance or increase in limits are then
commonly maintained by prudent tenants in similar buildings in the area by
tenants making similar uses.

                  b. Landlord's Insurance.

                           (i)      Landlord shall obtain, maintain and keep in
full force and effect the following insurance with companies authorized to do
business in the Commonwealth of Pennsylvania and having a rating of at least
A+XV (or its equivalent) by Best Rating Service or any successor thereto (or if
there be none, an organization having a national reputation in the field of
rating property insurance companies).

                                    (A) "All Risk" property insurance against
fire, theft, vandalism, malicious mischief, sprinkler leakage and such
additional perils as are now, or hereafter may be, included in a standard
extended coverage endorsement from time to time in general use in the
Commonwealth of Pennsylvania upon the Building and all plumbing, electrical,
mechanical and other operating systems therein and all improvements in the
Building (except Tenant's property as described in Section 9(a)(i) above), in an
amount equal to the full replacement cost thereof with an "agreed amount"
endorsement, with such deductibles as Tenant may reasonably approve, and with so
called "builder's risk" coverage during any period of construction at the
Premises.

                                    (B) Rental income insurance insuring
Landlord against abatement or loss of Fixed Basic Rent, including items of
Additional Rent, in case of fire or other casualty similarly insured against, in
an amount equal to the Fixed Basic Rent and Additional Rent for twelve months or
such longer period as Tenant may approve.

Landlord shall furnish to Tenant, no later than the Delivery Date and thereafter
annually throughout the Term, certificates addressed to Tenant as certificate
holder, evidencing the required insurance coverage, on the ACORD 27 form or
comparable form in which the insurer undertakes that the policy will not be
cancelled without thirty (30) days prior notice to Tenant.

                           (ii)     Beginning on the Commencement Date and
throughout the Term, Tenant shall pay the premiums for Landlord's insurance
required under Section 9(b) above. Premiums for the years in which the
Commencement Date and the termination date of the Term

                                      -4-
<PAGE>

occur shall be prorated. Tenant's premium payment shall be paid to Landlord
within thirty (30) days after Tenant's receipt of a copy of the insurer's
invoice and with the required insurance certificate. If the premiums for
Landlord's insurance exceed by five percent (5%) or more the premium cost at
which Tenant is able to purchase the same or better coverage from a company
meeting the standards set forth in Section 9(b)(i) and otherwise satisfying
Landlord's insurance requirements pursuant to any loan secured by a mortgage on
the Property ("Qualified Company"), then at its option Tenant may require that
Landlord's insurance be purchased from the Qualified Company of Tenant's choice
unless Landlord commits in writing to Tenant that Landlord will pay its own
insurance premiums to the extent they exceed the premium cost charged by the
Qualified Company selected by Tenant.

                           (iii)    Notwithstanding payment of insurance
premiums by Tenant as provided herein, Tenant acknowledges that it has no right
to receive any proceeds from any such insurance policies carried by Landlord
although subject to the terms of this Lease Landlord shall use such proceeds in
the repair and reconstruction of the Building and the Premises. Landlord will
not carry insurance of any kind on Tenant's furniture or furnishings, or on any
fixtures, equipment or other personal property of Tenant under this Lease, and
Landlord shall not be obligated to repair any damage thereto or replace the
same.

                  c. Failure to Insure. If either Landlord or Tenant shall fail
to obtain, and furnish certificate evidence as required above, of the insurance
required to be carried by it under this Section 9, (i) the party failing to
carry insurance shall be responsible for all losses suffered by the other party
which would have been covered had the required insurance been in effect at the
time of the loss, and (ii) if such failure continues for twenty (20) days after
notice from the other party, as evidenced by the failure to produce the required
certificate of coverage, the other party may purchase the required insurance,
with a term of up to twelve months, for the account of the defaulting party.

                  d. Waiver of Subrogation. Any policy or policies of fire,
extended coverage or similar casualty insurance, which either party obtains in
connection with the Building or Property shall include a clause or endorsement
denying the insurer any rights of subrogation against the other party (i.e.
Landlord or Tenant) for all perils covered by such policy. Should such waiver
not be available then the policy for which the waiver is not available must name
the other party as an additional named insured affording it the same coverage as
that provided the party obtaining such coverage. Any provision of this Lease to
the contrary notwithstanding, except as otherwise provided in Section 9(c)(i)
above in the case of a party's failure to carry the required insurance, Landlord
and Tenant hereby release the other from any and all liability or responsibility
to the other or anyone claiming through or under them by way of subrogation or
otherwise (a) from any and all liability for any loss or damage to the property
of the releasing party, (b) for any loss or damage that may result, directly or
indirectly, from the loss or damage to such property (including rental value and
business interruption), and (c) from legal liability for any loss or damage to
property (no matter who the owner of the property may be), all to the extent
that the releasing party's loss or damage is insured or, if not insured, was
insurable under commercially available "all risk" property insurance policies,
including additional coverages typically obtained by owners and tenants of
comparable buildings in the vicinity of the Building, even if such loss or
damage or legal liability shall be caused by or result from the fault or
negligence of the other party or anyone for whom such party may be responsible
and even if the

                                      -5-
<PAGE>

releasing party is self insured in whole or in part or the amount of the
releasing party's insurance is inadequate to cover the loss or damage or legal
liability. It is the intention of the parties that Landlord and Tenant shall
look solely to their respective insurance carriers for recovery against any such
property loss or damage or legal liability, without such insurance carriers
having any rights of subrogation against the other party.

         10. REPAIRS AND MAINTENANCE.

                  a. Obligations of Landlord.

                           (i)      At all times during the Term of this Lease
Landlord shall maintain and repair (including capital replacements as needed)
the structural elements of the land, parking lot and Building (including without
limitation the land, the foundations, the load bearing walls and, except as
otherwise provided in Section 10(b)(vi), the roof and roof membrane system) in
good condition and repair, reasonable wear and tear and damage by fire or other

Section 10(b). Except as provided under Section 10(b)(ii) below, Landlord shall
also be responsible for capital replacements (as determined in accordance with

shall make a capital expenditure which effectuates cost savings to Tenant in
Tenant's operation and maintenance of the Premises (other than one which is
required to be made pursuant to Section 12 below), then Tenant shall reimburse
Landlord for such capital expenditure to the extent of the savings.

                  b. Obligations of Tenant. Except to the extent the

the HVAC equipment which is warranted by the manufacturer and/or guaranteed by
the installer, Tenant shall provide the Landlord with a copy of the warranty

provided in Section 10(b)(ii) above. Tenant shall furnish a copy of every annual
inspection report (even if in draft form) to Landlord within fifteen (15) days
of receipt.

                           (iv)     Tenant shall keep the Premises clean and
free from dirt, rubbish, waste and debris at all times and shall be responsible

Landlord's expense and Landlord shall pay to Tenant, within thirty (30) days of
receipt of a written invoice from Tenant, the cost of such repairs incurred by
Tenant.

                           (vi)     Tenant shall not do anything or permit

voided.

                  c. Notice; Failure to Maintain. Tenant and Landlord shall give
one another written notice of the need for any maintenance or repair for which
other party is responsible, after which party responsible shall have a
reasonable opportunity, taking into account the impact of the problem on
Tenant's ability to use the Premises and the time needed to perform the repair,

                                      -7-
<PAGE>

obligations required of it under this Section 10(c) and if such failure
continues for thirty (30) days after notice from the other party, or such other
longer period as is reasonably necessary in all the circumstances to perform the
obligation, the other party may have the maintenance or repair (including
replacements) performed for the account of the defaulting party, and, to the
extent that the defaulting party is otherwise responsible for the cost of such
work under this Lease, may recover from the defaulting party the cost of the
work plus interest at the Default Rate from the date or dates incurred to the
date of full reimbursement.

         11. UTILITIES AND SERVICES. On or before the Commencement Date, Tenant

failure to supply or delay in supplying any such utilities and services or any
limitation, curtailment, rationing or restriction on use of water, electricity,
gas or any resource or form of energy or other service serving the Premises,
whether such results from mandatory restrictions or voluntary compliance with
guidelines. Landlord shall not be responsible to provide any water, gas, heat,
light, power, telephone, sewer, refuse disposal or other utilities or other
services prior to the Commencement Date and Tenant shall not be obligated for
the costs of same unless and until Tenant commences the Tenant Improvements (as

Premises and which continues for five (5) consecutive business days following
notice from Tenant to Landlord, then so long as same was not caused by Tenant or
a Tenant Party, Tenant shall be entitled to a full abatement of Fixed Basic Rent
and Additional Rent from the date of the interruption until such utility service
is restored.

         12. GOVERNMENTAL REGULATIONS.

                  a. Landlord and Tenant shall comply with all laws, ordinances,
notices, orders, rules, regulations and requirements of all federal, state and
municipal government or any department, commission, board of officer thereof
(collectively, "Governmental Regulations") relating to the Premises or to the
use or manner of use of the Property. Neither Landlord nor Tenant shall
knowingly do or commit, or suffer to be done or committed anywhere on the
Property, any act or thing contrary to any of the Governmental Regulations.

                  b. Landlord shall be responsible for the installation or
construction of capital improvements required for the Property to comply with
Governmental Regulations. The cost of such improvements shall be the
responsibility of Landlord if the applicable Governmental Regulation was enacted
prior to the Commencement Date, the responsibility of Tenant if the applicable
Governmental Regulation is enacted after the Commencement Date. If Landlord
shall purchase any item of capital equipment or make any capital improvements
the cost of

                                      -8-
<PAGE>

which is the responsibility of Tenant under this Section 12(b), then the costs
for same shall be amortized on a straight line basis beginning in the year of
installation and continuing for the useful life thereof, but not more than ten
(10) years, and Tenant shall reimburse Landlord only for that portion of the
amortized costs which falls within the Term of this Lease unless such
improvement is required due to Tenant's particular use or manner of use of the
Premises, in which case Tenant shall be responsible for the entire cost of the
improvement. Tenant's payment shall be due to Landlord within thirty days after
the later of completion of the applicable expenditure and Tenant's receipt of
Landlord's invoice, which invoice shall detail the improvement, the useful life
applied and the portion allocable to the Term.

the warehouse), equipment (including without limitation a telephone system), an
alarm system (Locknetics Key Card System) and other furnishings and fixtures
listed on Exhibit E (all of such existing items being referred to collectively
as the "Existing FF&E"). Landlord hereby leases the Existing FF&E to Tenant "AS
IS, WHERE IS" and without any representation or warranty whatsoever. Tenant
shall have the right to use, consume, remove, dispose of and/or replace the
Existing FF&E at Tenant's option in the ordinary course and conduct of its
business at any time and from time to time throughout the Term, without any
obligation to maintain, repair or replace any of the Existing FF&E, provided,
however, that Tenant shall repair and restore any damage or injury to the
Premises caused by installation or removal and provided further that before
removing any warehouse racking from the Premises, Tenant shall provide Landlord
with prior notice of its intention to do so at least thirty (30) days prior to
the date of removal and give Landlord an opportunity to elect to keep same and
store such racking for its use or the use of others at a location other than the
Premises. If Tenant elects to replace any of the Existing FF&E, then all such
replacements shall be the property of the Tenant and Tenant may remove any and
all replacement property at expiration of the Term, except that wiring and
non-trade fixtures integrated into the Building (such as alarm systems) shall
become part of the Building upon installation and may not be removed at
expiration of the Term without Landlord's consent.

                  b. During the Term, Tenant shall also have the right at its
cost from time to time and at any time to install in and remove from the
Premises any other of Tenant's furnishings, equipment and trade fixtures;
provided, however, that Tenant shall repair and restore any damage or injury to
the Premises caused by installation or removal.

                  c. Tenant shall have the right to make alterations, additions
and/or improvements to the Premises (collectively, the "Alterations") without
cost to Landlord, provided, however, that Landlord's prior written consent shall
be required for any structural Alteration, any Alteration expanding the size of
the Building or making any substantive change to the exterior appearance of the
Building, and any Alteration (or series of contemporaneous Alterations) costing
in excess of $50,000. Where Landlord's consent is required, Tenant shall present
plans and specifications to Landlord for Landlord's approval, which shall not be
unreasonably withheld or delayed, but may be conditioned upon compliance with
reasonable requirements of Landlord as provided in this Lease including, but not
limited to, the following: (i) Tenant supplies any necessary permits; (ii) such
alterations and improvements do not, in Landlord's

                                      -9-
<PAGE>

reasonable judgment, impair the structural strength of the Building; (iii)
Tenant takes or causes to be taken all steps that are otherwise required by
Section 14 of this Lease and that are required or permitted by law in order to
avoid the imposition of any mechanic's, laborer's or materialman's lien upon the
Building or the Property; (iv) Tenant uses a contractor approved by Landlord
such approval not to be unreasonably withheld, conditioned or delayed, it being
understood that union affiliation or non-affiliation shall not be a basis for
disapproval of a contractor. Landlord shall respond to Tenant requests for
consent within twenty (20) days after Tenant's submission. In connection with
any Alteration which changes the structure of the Building or the Building
Systems, whether or not same requires approval, Tenant shall provide Landlord
with as-built plans for same promptly following completion. Any and all
Alterations to the Premises which are constructed, installed or otherwise made
by Tenant shall be the property of Tenant until the expiration or sooner
termination of this Lease; at that time all such Alterations shall remain on the
Premises and become the property of Landlord without payment by Landlord unless,
at the time of granting its consent to the Alterations, Landlord conditioned its
consent in writing upon the restoration of the Premises to remove specified
portions of Alterations upon the termination of this Lease, in which event
Tenant will remove the specified portion of such Alterations and repair and
restore any damage to the Property.

         14. MECHANIC'S LIENS.

                  a. Tenant covenants that it shall not (and has no authority
to) create or allow any encumbrance against the Premises, the Property, or any
part of any thereof or of Landlord's interest therein.

                  b. Tenant covenants that it shall not suffer or permit to be
created, or to remain, any lien or claim thereof (arising out of any work done
or services, material, equipment or supplies furnished for or at the request of
Tenant or by or for any contractor or subcontractor of Tenant, other than such
furnished by Landlord) which is or may become a lien upon the Premises, the
Property, or any part of any thereof or the income therefrom or any fixture,
equipment or similar property therein.

                  c. If any lien or claim shall be filed, Tenant shall within
thirty (30) days after Tenant receives notice of the filing thereof, cause the
same to be discharged of record by payment, deposit, bond or otherwise. If
Tenant shall fail to cause such lien or claim to be discharged and removed from
record within that period and such failure continues for ten (10) additional
days after notice of default from Landlord to Tenant, then, without obligation
to investigate the validity thereof and in addition to any other right or remedy
Landlord may have, Landlord may, but shall not be obligated to, contest the lien
or claim or discharge it by payment, deposit, bond or otherwise; and Landlord
shall be entitled, if Landlord so decides, to compel the prosecution of an
action for the foreclosure of such lien by the lienor and to pay the amount of
the judgment in favor of the lienor with interest and costs. Any amounts so paid
by Landlord and all costs and expenses, including attorneys' fees, incurred by
Landlord in connection therewith, together with interest at the Default Rate
from the respective dates of Landlord's making of the payment or incurring of
the cost or expense, shall constitute Additional Rent payable by Tenant under
this Lease and shall be paid by Tenant to Landlord promptly on demand.

                  d. Notwithstanding anything to the contrary in this Lease or
in any other writing signed by Landlord, neither this Lease 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. Further, notwithstanding anything contained herein to
the contrary, nothing contained in or contemplated by this Lease shall be deemed
or construed in any way to constitute the consent or request on the part of
Landlord for the performance of any work or services or the furnishing of any
materials for which any lien could be filed against the Premises or the Property
or any part of any thereof, nor as giving Tenant any right, power, or authority
to contract for or permit the performance of any work or services or the
furnishing of any materials for which any lien could be filed against the
Premises, the Property or any part of any thereof.

representatives of Landlord and of any mortgagee or any prospective mortgagee to
enter the Premises at all reasonable times, with prior notice to Tenant, for the
purpose of (i) inspecting the Premises or (ii) making any necessary repairs to
the Premises or to the Building and performing any work therein. During the
progress of any work on the Premises or the Building, Landlord will attempt not
to inconvenience Tenant, but shall not be liable for inconvenience, annoyance,
disturbance, loss of business or other damage to Tenant by reason of making any
repair or by bringing or storing materials, supplies, tools and equipment in the
Premises during the performance of any work,

                                      -14-
<PAGE>

and the obligations of Tenant under this Lease shall not be thereby affected in
any manner whatsoever.

                  b. Landlord shall have the right at all reasonable times, with
prior notice to Tenant, to enter and to exhibit the Premises for the purpose of
inspection or showing the Premises in connection with a sale or mortgage and,
during the last twelve (12) months of the Term, to enter upon and to exhibit the
Premises to any prospective tenant.

                  c. Tenant shall have the right to retain at all times, and to
use in appropriate instances, keys to all doors within and to the Premises.

         18. DAMAGE BY FIRE OR OTHER CASUALTY.

                  a. If any of the improvements on the Premises are damaged or
destroyed by fire or other casualty, Tenant shall promptly notify Landlord
whereupon, unless one of the parties has exercised a termination right granted
in this Section 18, Landlord shall repair, rebuild or replace such damage and
restore the Premises to substantially the same condition as the Premises were in
immediately prior to such damage or destruction; provided, however, that as long
as Landlord has maintained and kept in effect the property insurance required to
be carried by Landlord under this Lease, Landlord shall only be obligated to
restore such damage or destruction to the extent of the proceeds of fire and
other extended coverage insurance policies.

                  b. The repair, rebuilding or replacement work shall be
commenced promptly and completed with due diligence, taking into account the
time required by Landlord to effect a settlement with, and procure insurance
proceeds from, the insurer, and for delays beyond Landlord's reasonable control.

                  c. If this Lease is not terminated pursuant to Section 18(f)
below, the net amount of any insurance proceeds recovered by reason of the
damage or destruction of the Building (meaning the gross insurance proceeds
excluding proceeds received pursuant to a rental coverage endorsement and the
cost of adjusting the insurance claim and collecting the insurance proceeds)
shall be applied towards the cost of restoration. Insurance deductible costs
incurred by Landlord, up to the approved deductible, shall be reimbursed by
Tenant upon completion of repairs.

                  d. Landlord's obligation or election to restore the Premises
under this Section or to terminate this Lease shall shall not, in any event,
include the repair, restoration or replacement of the fixtures, furniture or any
other personal property owned, installed, made by, or in the possession of
Tenant. Landlord's obligation to restore the Premises shall be subject to the
terms of any present or future institutional mortgage encumbering the Property,
and to the mortgagee's consent if required in such mortgage, provided however
that Landlord shall in no event be excused from restoration of damage affecting
less than 25% of the Building (whether because of a mortgage or otherwise)
unless one of the parties exercises a termination right granted in Section 18(f)
below.

                  e. If Tenant is unable in Tenant's reasonable judgment to use
the Premises or any part thereof due to fire or other casualty, Fixed Basic Rent
shall be abated in proportion to

                                      -15-
<PAGE>

the unusable portion of the Premises until such time as repairs and restoration
have been completed.

                  f. (i) If the Premises are damaged by fire or other casualty
such that more than 25% of the Building is reasonably expected to be unavailable
for Tenant's use for a period exceeding one hundred eighty (180) days from the
date of damage, then Tenant or Landlord may terminate this Lease by notice given
to the other within thirty (30) days after the date of damage. (ii) If the
Landlord has maintained in effect the property insurance coverage required under
this Lease and the damage is caused by a peril which is not covered by the
insurance, or if the insurance proceeds are not adequate to restore such damage,
then either party may terminate this Lease within thirty (30) days after the
damage, except that if Landlord exercises its termination right, Landlord shall
state the amount of the restoration cost which is reasonably anticipated to
exceed the available insurance proceeds and the reason therefore, and Tenant may
nullify the termination by undertaking in writing, within thirty days after
receipt of Landlord's termination notice, to cover the Landlord's cost of such
repairs to the extent that they exceed the available insurance proceeds. If the
excess restoration cost as reasonably estimated by Landlord exceeds three
months' Fixed Basic Rent, then Landlord may require reasonable evidence that
Tenant has the excess restoration costs available for reimbursement. (iii) If
the Premises are damaged by fire or other casualty during the last two years of
the Term and the damage affects more than 25% of the Building or is expected to
take more than thirty (30) days to repair, then either party may terminate this
Lease by notice given to the other within thirty days after the date of damage,
except that if Landlord exercises its termination right (pursuant to this
sentence only) at a time when Tenant has unexpired options to renew the Term,
then Tenant may nullify Landlord's termination by exercising Tenant's renewal
option within thirty (30) days after receipt of Landlord's notice of
termination. (iv) If release of insurance proceeds for restoration is subject to
mortgagee conditions and approval, then Tenant may terminate this Lease if
Landlord fails to confirm to Tenant, within sixty (60) days after the date of
damage, that the mortgagee's approval has been obtained and the insurance
proceeds have been or will be released for restoration of the Premises.

         19. NON-ABATEMENT OF RENT. Except as otherwise expressly set forth in
this Lease, there shall be no abatement or reduction of the Fixed Basic Rent,
Additional Rent or other sums payable under this Lease for any cause whatsoever
and this Lease shall not terminate, nor shall Tenant be entitled to surrender
the Premises, in the event of fire, casualty or condemnation.

         20. INDEMNIFICATION

                  a. Landlord hereby agrees to indemnify, defend and hold the
Tenant and its employees, agents and contractors harmless from any loss, costs
and damages (including reasonable attorney's fees and costs) suffered by Tenant,
its agents, employees or contractors, as a result of any claim by a third party,
its agents, employees or contractors arising from the negligence or misconduct
of Landlord or any of the Landlord Parties.

                  b. Tenant hereby agrees to indemnify, defend and hold the
Landlord and its employees, agents and contractors harmless from any loss, costs
and damages (including reasonable attorney's fees and costs) suffered by
Landlord, its agents, employees or contractors,

                                      -16-
<PAGE>

as a result of any claim by a third party, its agents, employees or contractors
arising from the negligence or misconduct of Tenant or any of the Tenant
Parties.

                  c. The indemnifying party shall have the right to designate
counsel acceptable to the other party, such approval not to be unreasonably
withheld, to assume the defense of any such third party claim on behalf of
itself and the indemnified party. The indemnified party shall not have the right
to settle any claim without the consent of the indemnifying party. This
indemnity shall survive the expiration of the Term or earlier termination of
this Lease.

         21. EMINENT DOMAIN

                  a. Total or Partial Taking. In the event of exercise of the
power of eminent domain whereby:

                           (i)      such portion of the Property is taken that
access to the Premises is permanently impaired thereby and in Tenant's
reasonable judgment reasonable alternate access will not be available by the
time the impairment takes effect; or

                           (ii)     more than ten percent (10%) of the parking
spaces are taken and cannot be otherwise replaced at the Premises, or

                           (iii)    or more than ten percent (10%) of the square
footage of the Building is taken;

then Tenant, shall have the right to terminate this Lease as of the date set
forth in Tenant's notice of termination to Landlord, which date shall be no
later than the date when possession of that part which was taken is required to
be delivered or surrendered to the condemning authority and no earlier than the
anticipated date of such delivery or surrender; and in such case all Fixed Basic
Rent and other charges shall be adjusted to the date of termination. A "taking"
as such term, is used in this Section 21 shall include a transfer of title or of
any interest in the Property by deed or other instrument in settlement of or in
lieu of transfer by operation of law incident to condemnation proceedings.

                  b. Temporary Taking. Notwithstanding anything hereinabove
provided, in the event of a taking of only the right to or for possession of the
Premises for a fixed period of time or for the duration of an emergency or other
temporary condition, then this Lease shall continue in full force and effect but
Fixed Basic Rent and Additional Rent shall abate for the duration, and to the
extent of, Tenant's dispossession. The above notwithstanding, if any such
temporary taking is reasonably anticipated to continue for a period in excess of
one hundred eighty (180) days, Tenant shall have the right to terminate this
Lease upon ten (10) days written notice to Landlord.

                  c. Tenant's Waiver. Regardless of whether this Lease shall
terminate, Tenant shall have no right to participate or share in any
condemnation claim, damage award or settlement in lieu thereof with respect to
any taking of any nature; provided, however, that Tenant shall not be precluded
from claiming or receiving payment for Tenant's relocation and moving expenses
and the value of Tenant's leasehold improvements and fixtures as may be

                                      -17-
<PAGE>

permitted under applicable law, except to the extent that the cost of same was
funded in whole or in part by Landlord.

         22. QUIET ENJOYMENT. Tenant, upon paying the Fixed Basic Rent,
Additional Rent and other charges herein required and observing and keeping all
covenants, agreements and conditions of this Lease, shall quietly have and enjoy
the Premises during the Term without hindrance or molestation by anyone claiming
by or through Landlord, subject, however, to the exceptions, reservations and
conditions of this Lease.

         23. ASSIGNMENT AND SUBLEASE.

                  a. As long as Tenant is operating for the Permitted Use in at
least 30% of the Building, Tenant may sublease up to seventy percent (70%) of
the Building at any time and from time to time, on such terms and conditions as
Tenant may elect, subject to the terms of this Lease. Upon execution and
delivery of a sublease, Tenant shall notify Landlord of the subtenant's name,
its use, and the portion of the Building subleased.

                  b. "Affiliate" shall mean any entity (and the word entity as
used herein shall mean any natural individual and any corporation, partnership,
limited liability company or other entity) which acquires all or substantially
all of the shares of Tenant, any entity owned in whole or in part by Tenant, and
any entity under common control with Tenant. Tenant may assign this Lease to any
Affiliate or to any entity which acquires all or substantially all of the assets
of Tenant at the Premises, as long as, if the assignee is not a public company,
either (i) the assignee is an entity which issues audited financial statements
prepared in accordance with generally accepted accounting principles separate
from any parent entity or (ii) the parent entity or other entity acceptable to
Landlord guarantees this Lease. In addition, the transfer of Tenant shares as
part of a public offering, the transfer of Tenant shares among existing
shareholders, their families and heirs and trusts for the benefit of such
shareholders, the transfer of Tenant shares on a publicly traded exchange, and
the transfer of up to an aggregate of 49% of Tenant shares to outsiders in a
private transaction shall be freely permitted.

                  c. Transfer of Tenant's rights other than pursuant to Sections
23(a) and 23(b) are referred to herein as "Third Party Transfers." If Tenant
proposes a Third Party Transfer, Tenant shall first give written notice of its
intent to Landlord, setting forth the target date for the proposed assignment or
sublease and the amount of space involved in the case of a sublease. Tenant
shall furnish to Landlord the identity of the transferee, the space involved and
the proposed use. Landlord shall have a period of fifteen(15) days after the
receipt of Tenant's notice within which to give Tenant written notice of
Landlord's election to terminate the Lease. If Landlord elects to terminate, the
termination shall take effect as of the target date for the proposed assignment
or sublease as set forth in Tenant's notice to Landlord.

                  d. If Landlord elects not to terminate this Lease pursuant to
Section 23(c), Tenant shall provide written notice of any Third Party Transfer
to Landlord prior to the effective date of any such Third Party Transfer,
setting forth the identity of the transferee, the proposed use, the space
involved and plans for layout and partitioning of space in the case of any
sublease. Tenant shall provide to Landlord such financial statements and other
information reasonably

                                      -18-
<PAGE>

requested by Landlord in connection with the proposed Third Party Transfer which
information may be considered by Landlord in connection with its approval or
rejection of the Third Party Transfer. The proposed Third Party Transfer shall
be subject to Landlord's approval, which shall not be unreasonably withheld,
delayed or conditioned, provided however that at Landlord's option Landlord may
condition its consent to any proposed Third Party Transfer on the execution of
an amendment to this Lease, effective as of the date of the Third Party
Transfer, deleting, as to any then unexercised Tenant options or rights, Article
37 (captioned Renewal Option), Article 38 (captioned Right to Expand) and/or
Article 41 (captioned Right of First Offer to Purchase). Landlord shall respond
to Tenant requests within thirty (30) days after receipt of Tenant's request
accompanied by the information required herein.

                  e. In the case of any assignment of this Lease, the assignee
shall assume, by written instrument, all of the obligations of the Tenant as
provided by this Lease, and an original executed counterpart of such assumption
agreement shall be furnished to the Landlord within ten days after the effective
date of the assignment. Any sublease shall expressly acknowledge that said
subtenant's rights against Landlord shall be no greater than those of Tenant.

                  f. The Tenant and each assignee shall be and remain liable for
the observance of all the covenants and provisions of this Lease, including, but
not limited to, the payment of Fixed Basic Rent and Additional Rent reserved
herein, through the entire Term, as the same may be renewed, extended or
otherwise modified.

                  g. In any event, the acceptance by the Landlord of any rent
from the assignee or from any of the subtenants or the failure of the Landlord
to insist upon a strict performance of any of the terms, conditions and
covenants herein shall not release the Tenant herein, nor any assignee or
subtenant, from any and all of the obligations to be performed by it in
accordance herewith during and for the entire Term.

                  h. Tenant shall pay to Landlord up to one Thousand Five
Hundred Dollars ($1,500.00) to cover the legal costs and fees it incurs in
connection with a consent to any sublet or assignment.

                  i. Without limiting any of the provisions of this Section 23,
if pursuant to the Federal Bankruptcy Code (herein referred to as the "Code"),
or any similar law hereafter enacted having the same general purpose, Tenant is
permitted to assign this Lease notwithstanding the restrictions contained in
this Lease, adequate assurance of future performance by an assignee expressly
permitted under such Code shall be deemed to mean the deposit of cash security
in an amount equal to the sum of one year's Fixed Basic Rent, which deposit
shall be held by Landlord for the balance of the Term, without interest, as
security for the full performance of all of Tenant's obligations under this
Lease, to be held and applied in the manner specified for any security deposit
required hereunder.

                  j. Except as specifically provided above, Tenant shall not
assign this Lease or sublet all or any portion of the Premises. Tenant shall not
mortgage, sublease, transfer this Lease, the Premises or the Tenant's interest
therein, nor shall Tenant pledge its interest in this Lease or in any security
deposit required hereunder without in each instance Landlord's prior written
consent.

                                      -19-
<PAGE>

         24. SUBORDINATION. At the request of Landlord or Landlord's mortgagee,
Tenant shall enter into an agreement pursuant to which this Lease and Tenant's
rights under this Lease shall be subject and subordinate at all times in lien
and priority to any first mortgage hereafter placed upon the Property, and to
all renewals, modifications, consolidations and extensions thereof, in form and
content reasonably acceptable to Landlord's mortgagee, provided, however that
such agreement shall contain provisions mutually acceptable to Tenant and such
lender under which any holder of such lien or mortgage agrees not to disturb the
use and occupancy of the Premises in accordance with the terms of this Lease
upon any foreclosure or other acquisition of Landlord's rights in the Lease.
Landlord agrees to cause its current mortgage lender to execute and deliver to
Tenant a subordination, non-disturbance and attornment agreement in a form
mutually acceptable to both Tenant and such lender.

         25. CURING DEFAULTS. If either party defaults in the performance of any
of its obligations under this Lease, the other party may, without any obligation
to do so and in addition to any other rights it may have in law or equity, elect
to cure such default on behalf of the defaulting party after written notice as
provided elsewhere in this Lease (except in the case of emergency) to the
defaulting party. The defaulting party shall reimburse the other party upon
demand for any sums paid or costs incurred in curing such default, including
interest thereon at the Default Rate from the respective dates of the curing
party's making the payments and incurring such costs, provided however that if
Tenant cures a Landlord obligation for which Tenant was obligated to pay (as for
example, the premiums for property insurance), then to the extent Tenant was
obligated to make payment under this Lease, Tenant may not recover its
expenditure from Landlord.

         26. SURRENDER.

                  a. At the expiration of the Term or earlier termination of
this Lease, Tenant shall promptly yield up the Premises and all Alterations
thereto, and all Building operating fixtures and equipment in a condition which
is clean of garbage and debris and broom clean and in the same condition, order
and repair in which they are required to be kept throughout the Term, ordinary
wear and tear and damage by fire or other casualty excepted.

                  b. If Tenant, or any person claiming through Tenant, continues
to occupy the Premises after the expiration of the Term or earlier termination
of this Lease or any renewal thereof without prior written consent of Landlord,
the tenancy under this Lease shall become, at the option of Landlord, expressed
in a written notice to Tenant and not otherwise, a tenancy from month-to-month,
terminable by Landlord on thirty (30) days prior notice, under the same terms
and conditions set forth in this Lease; (ii) the Fixed Basic Rent for each month
or portion thereof during such continued occupancy shall be one hundred fifty
percent (150%) of the Fixed Basic Rent for the last month of the Term. Anything
to the contrary notwithstanding, any holding over by Tenant without Landlord's
prior written consent shall constitute an Event of Default under this Lease and
shall be subject to all the remedies set forth in Subsection 27(b) of this
Lease.

         27. DEFAULTS-REMEDIES.

                  a. Tenant Defaults. It shall be an Event of Default by Tenant
under this Lease if any one or more of the following events occurs:

                                      -20-
<PAGE>

                           (i)      Tenant fails to pay any and all installments
of Fixed Basic Rent and such failure continues for fifteen (15) days following
written notice from Landlord to Tenant.

                           (ii)     Tenant fails to pay any and all Additional
Rent or any other charges or payments due and payable under this Lease whether
or not herein included as rent and such failure continues for twenty (20) days
following written notice from Landlord to Tenant.

                           (iii)    Tenant fails to maintain liability insurance
for the benefit of Tenant and Landlord as required this Lease and such failure
continues for twenty (20) days following written notice from Landlord to Tenant.

                           (iv)     Tenant fails to furnish an estoppel
certificate within the time required under Section 35 of this Lease and such
failure continues for ten (10) days following a second written request from
Landlord to Tenant.

                           (v)      Tenant violates, fails to perform or
otherwise breaches any agreement, term, covenant or condition contained in this
Lease (other than as described in Subsections 27(a)(i) - 27(a)(iv) above) and
such failure continues for thirty (30) days following notice from Landlord to
Tenant, provided however that if such failure is capable of cure but cannot
reasonably be cured within thirty (30) days, then it shall not be an Event of
Default as long as Tenant commences to cure and proceeds with diligence until
the failure is cured.

                           (vi)     Tenant makes an assignment for the benefit
of creditors or files a petition in bankruptcy or for reorganization or for an
arrangement with creditors under any federal or state law (in each case, a
"Bankruptcy Proceeding"), or a Bankruptcy Proceeding is filed against Tenant and
is not stayed, dismissed or discharged within ninety (90) consecutive days.

                           (vii)    Any of the events enumerated in Subsection
(a)(vii) of this Section 27 happens to any guarantor of this Lease.

                  b. Landlord Remedies. Upon the occurrence of an event of
default under this Lease, Landlord shall have all of the following rights:

                           (i)      With respect to defaults in the payment of
Fixed Basic Rent, Landlord may charge a late payment charges and/or interest at
the Default Rate pursuant to Section 8 of this Lease. If Landlord incurs a late
charge in connection with any payment which Tenant has failed to make within the
times required in this Lease, Tenant shall pay Landlord, in addition to such
payment due, the full amount of such late charge incurred by Landlord. Nothing
in this Lease shall be construed as waiving any rights of Landlord arising out
of any default of Tenant, by reason of Landlord's imposing or accepting any such
late charge(s) and/or interest; the right to collect such late charge(s) and/or
interest is separate and apart from any rights relating to remedies of Landlord
after default by Tenant including, without limitation, the rights and remedies
of Landlord provided herein.

                                      -21-
<PAGE>

                           (ii)     Landlord may at any time and from time to
time bring one or more actions to recover amounts due from Tenant, with interest
at the Default Rate from the date due to the date full reimbursement is
received, plus Landlord's enforcement costs.

                           (iii)    Landlord may cure Tenant's Event of Default
as elsewhere provided in this Lease.

                           (iv)     Landlord may re-enter the Premises by any
suitable action or proceeding at law, without being liable for prosecution or
damages therefor, and Landlord may repossess and enjoy the Premises. Upon
recovering possession of the Premises after an Event of Default by Tenant,
Landlord may, at Landlord's option, either terminate this Lease or make such
alterations and repairs as may be necessary, as reasonably determined by
Landlord, in order to relet the Premises and may relet the Premises or any part
or parts thereof, either in Landlord's name or otherwise, for a term or terms
which may, at Landlord's option, be less than or exceed the period which would
otherwise have constituted the balance of the Term and at such rent or rents and
upon such other terms and conditions as in Landlord's sole discretion may seem
advisable and to such person or persons as may in Landlord's discretion seem
best; upon each such reletting all rents received by Landlord from such
reletting shall be applied as follows: first, to the payment of any costs and
expenses of such reletting, including all costs of alterations and repairs;
second, to the payment of any indebtedness other than Fixed Basic Rent,
Additional Rent or other charges due hereunder from Tenant to Landlord; third,
to the payment of Fixed Basic Rent, Additional Rent and other charges due and
unpaid hereunder; and the residue, if any, shall be held by Landlord and applied
in payment of future rent as it may become due and payable hereunder. If rentals
received from reletting during any month are less than that to be paid during
that month by Tenant, Tenant shall pay any such deficiency to Landlord. Such
deficiency shall be calculated and paid monthly. No such re-entry or taking
possession of the Premises or the making of alterations or improvements thereto
or the reletting thereof shall be construed as an election on the part of
Landlord to terminate this Lease unless written notice of termination is given
to Tenant. Notwithstanding any such reletting without termination, Landlord may
at any time thereafter elect to terminate this Lease for such previous breach.
After obtaining possession of the Premises, Landlord shall use commercially
reasonable efforts to re-let the Premises.

                           (v)      Landlord may terminate this Lease and the
Term without any right on the part of Tenant to waive the forfeiture by payment
of any sum due or by other performance of any condition, term or covenant
broken.

                           (vi)     CONFESSION OF JUDGMENT FOR POSSESSION. UPON
THE OCCURRENCE OF AN EVENT OF DEFAULT UNDER SECTION 27(a)(i) OR UPON THE
EXPIRATION OF THE TERM OF THIS LEASE, FOR THE PURPOSE OF OBTAINING POSSESSION OF
THE PREMISES, TENANT HEREBY AUTHORIZES AND EMPOWERS THE PROTHONOTARY OR ANY
ATTORNEY OF ANY COURT OF RECORD IN THE COMMONWEALTH OF PENNSYLVANIA OR
ELSEWHERE, AS ATTORNEY FOR TENANT AND ALL PERSONS CLAIMING UNDER OR THROUGH
TENANT, TO APPEAR FOR AND CONFESS JUDGMENT AGAINST TENANT FOR POSSESSION OF THE
PREMISES, AND AGAINST ALL PERSONS CLAIMING UNDER OR THROUGH TENANT, IN FAVOR OF
LANDLORD, FOR RECOVERY BY LANDLORD OF POSSESSION THEREOF, FOR WHICH THIS
AGREEMENT OR A COPY HEREOF

                                      -22-
<PAGE>

VERIFIED BY AFFIDAVIT, SHALL BE A SUFFICIENT WARRANT; AND THEREUPON A WRIT OF
POSSESSION MAY IMMEDIATELY ISSUE FOR POSSESSION OF THE PREMISES, WITHOUT ANY
PRIOR WRIT OR PROCEEDING WHATSOEVER AND WITHOUT ANY STAY OF EXECUTION. IF FOR
ANY REASON AFTER SUCH ACTION HAS BEEN COMMENCED THE SAME SHALL BE TERMINATED AND
THE POSSESSION OF THE PREMISES REMAINS IN OR IS RESTORED TO TENANT, LANDLORD
SHALL HAVE THE RIGHT UPON THE OCCURRENCE OF ANY SUBSEQUENT EVENT OF DEFAULT
UNDER SECTION 26(a)(i) TO CONFESS JUDGMENT IN ONE OR MORE FURTHER ACTIONS IN THE
MANNER AND FORM SET FORTH ABOVE TO RECOVER POSSESSION OF SAID PREMISES FOR SUCH
SUBSEQUENT DEFAULT. NO SUCH TERMINATION OF THIS LEASE, NOR TAKING, NOR
RECOVERING POSSESSION OF THE PREMISES SHALL DEPRIVE LANDLORD OF ANY REMEDIES OR
ACTION AGAINST TENANT FOR FIXED BASIC RENT, ADDITIONAL RENT OR FOR OTHER SUMS
DUE HEREUNDER OR FOR DAMAGES DUE OR TO BECOME DUE FOR THE BREACH OF ANY
CONDITION OR COVENANT HEREIN CONTAINED, NOR SHALL THE BRINGING OF ANY SUCH
ACTION FOR RENT AND/OR OTHER SUMS DUE HEREUNDER, OR BREACH OF COVENANT OR
CONDITION NOR THE RESORT TO ANY OTHER REMEDY HEREIN PROVIDED FOR THE RECOVERY OF
RENT AND/OR OTHER SUMS DUE HEREUNDER OR DAMAGES FOR SUCH BREACH BE CONSTRUED AS
A WAIVER OF THE RIGHT TO INSIST UPON THE FORFEITURE AND TO OBTAIN POSSESSION IN
THE MANNER HEREIN PROVIDED.

                  c. Damages. If Landlord shall terminate this Lease after the
occurrence of an Event of Default, Tenant shall be and remain liable to Landlord
in an amount computed as follows: (A) an amount equal to the sum of all Rent
then in arrears; plus (B) all costs and expenses actually incurred by Landlord
in connection with the reletting of the Premises (other than those costs for

                  e. Landlord Defaults. It shall be an event of default by
Landlord under this Lease if any one or more of the following events occurs:

                           (i)      Landlord fails to maintain property

(20) days following written notice from Tenant to Landlord.

                           (ii)     Landlord fails to substantially complete the
Site Work required under Section 3(a) within thirty (30) days following the

Tenant under Section 23(d) regarding Third Party Transfers or Section 13(c)
regarding proposed Alterations within the time set forth in the applicable
Section and such failure continues for ten (10) days following a second request

                           (iv)     Landlord violates, fails to perform or
otherwise breaches any agreement, term, covenant or condition contained in this
Lease and such failure continues for thirty (30) days following notice from
Tenant to Landlord, provided however that if such failure is capable of cure but
cannot reasonably be cured within thirty (30) days, then it shall not be an
event of default as long as Landlord commences to cure and proceeds with
diligence until the failure is cured.

                  f. Tenant Remedies. Upon the occurrence of an event of default
under this Lease by Landlord, Tenant shall have all of the following rights:

                           (i)      Tenant may at any time and from time to time
bring one or more actions to recover amounts due from Landlord, with interest at

as elsewhere provided in this Lease.

                           (iii)    With respect to an event of default arising
out of Landlord's failure to disburse the Improvement Allowance in accordance
with the terms of the Work Letter, Tenant may upon written notice to Landlord

substantially completes the Site Work. Furthermore, in such event and during the
period of such event of default, Landlord, at its cost, shall provide
alternative parking and transportation services in order to provide parking
capacity approximately the same as that which will be provided by the Site Work.

                  g. Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to either party 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 or by statute.

                  h. Consequential, Indirect, or Punitive Damages.

arising in connection with this Lease.

         28. BROKER'S COMMISSION. Landlord and Tenant represent and warrant to
one another that the Broker (as defined in the Preamble) is the sole broker with
whom Landlord and Tenant has dealt in bringing about this Lease. The fees of the
Broker named in the Preamble shall be paid by the Landlord in accordance with
separate written agreements with the Broker. Landlord and Tenant agree to
indemnify and hold one another harmless from any and all claims of other brokers
or other intermediaries claiming entitlement to a commission or fee by reason of
dealings with the indemnifying party. Notwithstanding the foregoing, the parties
acknowledge that Cushman and Wakefield of Pennsylvania, Inc. ("C&W") has been
involved in the sale of the Property to Landlord, and that Tenant has no
liability to C&W or to Landlord with respect to C&W.

                Philadelphia, PA 19103

Any other request or correspondence may be given in writing by any such other
means as such party desires, effective upon receipt by the addressee, but Major
Notices shall not constitute notice for purposes of this Lease unless given in
the manner prescribed above. Either party may at any time, in the manner set
forth for giving notices to the other, specify a different address to which
notices to it shall thereafter be sent. Notices given by messenger delivery or
overnight courier shall be effective upon delivery; notices given by certified
mail, return receipt requested shall be effective upon receipt or rejection of
receipt by the addressee.

         30. INABILITY TO PERFORM.If either party is delayed or prevented from
performing any of its obligations under this Lease by reason of strike, labor
troubles, or any cause whatsoever beyond that party's control, the period of
such delay or such prevention shall be deemed added to the time herein provided
for the performance of any such obligation, provided, however that nothing
herein shall be deemed to extend any time periods giving rise to a right of
termination or rent abatement such as those set forth in Section 11, Section 18
and Section 27.f(iv), and further provided that Tenant's obligation to pay Fixed
Basic Rent shall commence no later than six (6) months after the actual Delivery
Date.

         31. SURVIVAL. Notwithstanding anything to the contrary contained in
this Lease, the expiration of the Term, whether by lapse of time or otherwise,
shall not relieve either party from its obligations accruing prior to the
expiration of the Term.

         32. FINANCIAL STATEMENTS. Upon Landlord's written request no more
frequently than once each year, Tenant shall deliver to Landlord Tenant's most
recent annual audited financial statements which shall be prepared in accordance
with generally accepted accounting principles consistently applied. Landlord
shall keep all financial statements delivered to it confidential but shall be
permitted upon written notice to Tenant to deliver same to its lender(s), as
well as prospective lenders or purchasers of all or a portion of the Property or
Landlord's interest therein so long as such parties receiving such information
agree to keep same confidential. Notwithstanding the foregoing, if and when
shares in the Tenant are publicly traded, Landlord shall no longer be required
to maintain such confidentiality and provided the financial statements described
herein are readily available to the public, Tenant shall not be required to
provide same upon Landlord's request. Further, if as a result of acquisition by
another entity separate financial statements are no longer available for Tenant
at a time when Tenant's shares are not publicly traded, the requirement for the
Tenant to deliver financial statements under this Section 32 shall terminate if
this Lease is guaranteed by the acquiring entity or other entity acceptable to
Landlord.

         33. WAIVER OF INVALIDITY OF LEASE. Each party agrees that it will not
raise or assert as a defense to any obligation under the Lease or make any claim
that the Lease is invalid or

                                      -26-
<PAGE>

unenforceable due to any failure of this document to comply with ministerial
requirements including, without limitation, requirements for corporate seals,
attestations, witnesses, notarizations or other similar requirements and each
party hereby waives the right to assert any such defenses or make any claim of
invalidity or unenforceability due to any of the foregoing.

         34. SECURITY DEPOSIT.

                  a. On or before July 31, 2003 Tenant shall deposit with
Landlord, and shall thereafter maintain in effect through a date which is ninety
(90) days following the expiration of the Term, as same may be extended, a
letter of credit in the amount of the Security Deposit, in the form attached
hereto as Exhibit F (the "Letter of Credit") or such other form as may be
approved by Landlord, which approval shall not be unreasonably withheld so long
as it is generally consistent with the form attached. Landlord shall hold the
Letter of Credit as security for the full performance by Tenant of all terms,
covenants and conditions of this Lease. Upon the occurrence of an Event of
Default by Tenant involving the failure to pay money, Landlord may draw upon the
Letter of Credit in the amount owed by Tenant. It is understood that the
proceeds of the Letter of Credit are not to be considered as the last rental due
under this Lease. If at any time during the Term of this Lease, Landlord draws
against the Letter of Credit in whole or in part in order to cure an Event of
Default, Tenant shall within ten (10) business days after demand by Landlord
tender to Landlord a replacement Letter of Credit in the full amount required
hereunder. If the Term is then continuing, and Landlord has received notice from
the banking institution issuing the Letter of Credit that the Letter of Credit
will not be renewed, Tenant shall deliver to Landlord a replacement Letter of
Credit no later than twenty (20) days after Landlord's receipt of such notice.
If Tenant shall fail to timely deliver a replacement Letter of Credit as
aforesaid, then Landlord shall be entitled to draw immediately under the Letter
of Credit in Landlord's possession, and shall hold the funds so drawn as a cash
security deposit.

                  b. The initial amount of the Security Deposit, as set forth in
the Basic Lease Provisions and Definitions in the Preamble of this Lease, shall
be reduced to the sum of $250,000 at such time as Tenant has achieved three (3)
consecutive quarters of profitability, as demonstrated by Tenant's quarterly
financial statements prepared in accordance with generally accepted accounting
principles and certified by Tenant's chief financial officer. In such event
Landlord shall cooperate with Tenant in connection with such reduction,
including confirming its acceptance of the applicable amendment to the Letter of
Credit.

                  c. The Letter of Credit (or cash if the Security Deposit is
held in cash) shall be returned to Tenant no later than thirty (30) days after
expiration of the Term and surrender of the Premises. If Landlord shall fail to
refund the Security Deposit or surrender the then Current Letter of Credit
within thirty (30) days after Tenant's request, then in the case of a cash
Security Deposit Tenant shall be entitled to recover from Landlord, in addition
to the Security Deposit, interest at the Default Rate from the date due to the
date the cash is received by Tenant, and in the case of the Letter of Credit,
Tenant shall be entitled to recover from Landlord Interest at the Default Rate
for the period of such delay in receiving the original Letter of Credit back
from Landlord.

                                      -27-
<PAGE>

                  d. Landlord shall be responsible for any bank fees associated
with the transfer of the Letter of Credit to a successor owner of the Property
in connection with the sale of the Property and the assignment of this Lease.

         35. ESTOPPEL CERTIFICATE. Tenant shall from time to time, within ten
(10) days after Tenant's receipt of Landlord's written request or that of any
mortgagee of Landlord, execute and deliver to Landlord a written instrument,
substantially in the form attached hereto as Exhibit D (the "Tenant Estoppel
Certificate"), stating such exceptions to the contents thereof as may be
applicable.

         36. MISCELLANEOUS.

                  a. Required Approval. The submission of this Lease for
examination does not constitute an offer to lease, or a reservation of or option
for the Premises, and this Lease becomes effective only upon execution and
delivery thereof by both Landlord and Tenant.

                  b. Non Waiver. The failure of either party hereto in any one
or more instances to insist upon the strict performance of any one or more of
the agreements, terms, covenants, conditions or obligations of this Lease, or to
exercise any right, remedy or election herein contained, shall not be construed
as a waiver or relinquishment of the right to insist upon such performance or
exercise in the future, and such right shall continue and remain in full force
and effect with respect to any subsequent breach, act or omission.

                  c. Partial Payment. No payment by Tenant or receipt by
Landlord of a lesser amount than the correct Fixed Basic Rent or Additional Rent
due hereunder shall be deemed to be other than a payment on account, nor shall
any endorsement or statement on any check or any letter accompanying any check
or payment be deemed to effect or evidence an accord and satisfaction and
Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance or pursue any other remedy in this Lease or at law
provided.

                  d. Entire Agreement. This Lease constitutes the entire
agreement between the parties relating to the subject matter contained herein.
Neither party hereto has made any representations or promises to the other
except as expressly contained herein. This Lease supersedes all prior
negotiations, agreements, informational brochures, letters, promotional
information and other statements and materials made or furnished by Landlord or
its agents. No agreement hereinafter made shall be effective to change, modify,
discharge or effect an abandonment of this Lease, in whole or in part, unless
such agreement is in writing and signed by the party against whom enforcement of
the change, modification, discharge or abandonment is sought.

                  e. Partial Invalidity. If any of the provisions of this Lease,
or the application thereof to any person or circumstances, shall, to any extent,
be invalid or unenforceable, the remainder of this Lease, or the application of
such provision or provisions to persons or circumstances other than those as to
whom or which it is held invalid or unenforceable, shall not be affected
thereby, and every provision of this Lease shall be valid and enforceable to the
fullest extent permitted by law.

                                      -28-

                  f. Choice of Law. This Lease has been executed and delivered
in the Commonwealth of Pennsylvania and shall be construed in accordance with
the laws of the Commonwealth of Pennsylvania. Any action brought to enforce or
interpret this Lease shall be brought in the court of appropriate jurisdiction
in the county in which the Building is located. Should any provision of this
Lease require judicial interpretation, it is agreed that the court interpreting
or considering same shall not apply the presumption that the terms hereof shall
be more strictly construed against a party by reason of the rule or conclusion
that a document should be construed more strictly against the party who itself
or through its agent prepared the same. It is agreed and stipulated that all
parties hereto have participated equally in the preparation of this Lease and
that legal counsel was consulted by each responsible party before the execution
of this Lease.

                  g. Recordation. At Tenant's option, the parties will execute
and acknowledge a short form memorandum of lease to be recorded at Tenant's
expense.

                  h. No Joint Venture. This Lease shall create only the
relationship of Landlord and Tenant between Landlord and Tenant and no estate
shall pass out of Landlord. Nothing herein is intended to be construed as
creating a joint venture or partnership relationship between the parties hereto.

                  i. No Third Party Beneficiaries. Notwithstanding anything to
the contrary contained herein, no provision of this Lease is intended to benefit
any party other than the signatories hereto and their permitted heirs, personal
representatives, successors and assigns, and no provision of this Lease shall be
enforceable by any other party.

                  j. Exhibits. All exhibits referred to in this Lease are
attached hereto and shall be deemed an integral part hereof.

                  k. Captions. The captions included in this Lease, whether for
sections, subsections, paragraphs, Table of Contents, Exhibits, or otherwise,
are inserted and included solely for convenience and shall not be considered or
given any effect in construing the provisions hereof, and are not to be used in
interpreting this Lease or for any other purpose in the event of any
controversy.

                  l. Representations. Landlord has made no representation,
agreement, condition, warranty, understanding, or promise, either oral or
written, other than as set forth herein, with respect to the Lease, the
Property, the Premises, or otherwise.

                  m. Gender; Plural Terms; Persons. The masculine, feminine, or
neuter pronoun shall each include the masculine, feminine, and neuter genders. A
reference to person shall mean a natural person, a trustee, a corporation, a
partnership and any other form of legal entity. All references (including

         37. RENEWAL OPTION. Tenant is hereby granted two (2) options to renew
this Lease upon the following terms and conditions:

                                      -29-
<PAGE>

                  a. At the time of the exercise of the option to renew and at
the time of the said renewal, there shall not have occurred an Event of Default
by Tenant under this Lease which remains uncured.

                  b. Notice of the exercise of the option shall be sent to the
Landlord in writing at least twelve (12) months before the expiration of the
Term.

                  c. Each renewal term shall be for a period of five (5) years,
to commence at the expiration of the preceding Term and all of the terms and
conditions of this Lease, other than the Fixed Basic Rent, shall apply during
such renewal term.

                  d. The annual Fixed Basic Rent to be paid during the first
renewal term shall be the fair rental value per square foot of the Premises at
the commencement of the renewal term. The annual Fixed Basic Rent to be paid
during the second renewal term shall be the fair rental value per square foot of
the Premises at the commencement of the second renewal term. Within sixty (60)
days after Tenant's notice of election to renew, the Landlord shall notify
Tenant of Landlord's opinion of the fair rental value. Should Tenant dispute
Landlord's determination, then the Tenant shall be free to, at the Tenant's sole
cost and expense, employ the services of an appraiser familiar with buildings
located within the metropolitan Philadelphia, Pennsylvania area comparable to
the Building, who shall be a member of MAI and who shall render an appraisal. If
the Landlord and the Tenant's appraiser cannot agree on the fair rental value,
Landlord shall, at Landlord's sole cost and expense, employ the services of an
appraiser familiar with buildings located with the metropolitan Philadelphia,
Pennsylvania area comparable to the Building who shall be a member of MAI and
who shall render an appraisal. If the two appraisers cannot agree on the fair
rental value, or in such case, on an independent appraiser acceptable to both,
either Landlord or Tenant may request the American Arbitration Association to
appoint such independent appraiser who shall be a member of MAI familiar with
comparable buildings in the area of the Building who shall render an appraisal,
and in such event the judgment of a majority of the three appraisers shall be
final and binding upon the parties. The parties shall share equally in the cost
of any third such independent appraiser. Pending resolution of the issue of fair
rental value, the Tenant shall pay the Landlord as of commencement of the
renewal term, the Fixed Basic Rent for the preceding lease year, subject to
retroactive adjustment upon final determination of this issue.

         38. RIGHT TO EXPAND.

                  a. Landlord hereby grants to Tenant the one-time right (the
"Expansion Option") during the Term to expand the Building up to fifty thousand
(50,000) rentable square feet (but no less than thirty thousand (30,000)
rentable square feet) (the "Expansion Space") within the Expansion Space Area
shown on Exhibit G attached to this Lease, in accordance with plans and
specifications for same (the "Expansion Improvements Plans") approved by Tenant
and Landlord and all applicable governmental authorities with jurisdiction over
the Property. The Expansion Option shall not include the right to increase the
rentable square feet contained within the Building on its current footprint by
adding mezzanines or otherwise, all of which additions being subject to the
provisions of Section 13 of this Lease.

                                      -30-
<PAGE>

                  b. The Expansion Option shall be exercised by Tenant, if at
all, by written notice (the "Expansion Exercise Notice") delivered to Landlord
at any time after the Commencement Date, provided however that if the Expansion
Exercise Notice is given at a time when fewer than six years remain in the then
current Term, the then current Term shall be extended to the last day of the
month in which occurs the fifth anniversary of the date that Tenant takes
occupancy of the improved Expansion Space (exclusive of any unexpired renewal
terms, which shall remain in effect) . The Expansion Option may only be
exercised by the named Tenant hereunder or an Affiliate assignee of the named
Tenant.

                  c. During the sixty (60) day period following Tenant's
Expansion Exercise Notice, Landlord and Tenant shall negotiate the details of
construction and Fixed Basic Rent for the Expansion Space. If the parties are
unable to reach agreement within said sixty (60) day period, then at its option
Tenant may, upon acquisition of necessary governmental permits and approvals,
construct its addition within the Expansion Space at Tenant's own expense
subject only to Landlord's approval of the Expansion Improvements Plans, which
approval shall not be unreasonably withheld, conditioned or delayed as long as
the addition is structurally sound with an exterior reasonably complementary to
the rest of the Building, and Tenant may occupy the Expansion Space without
increase in the Fixed Basic Rent until the expiration of the Term of this Lease,
whereupon such improvements shall become the property of Landlord without
compensation.

         39. ADDITIONAL DEFINITIONS.

                  a. "Date of this Lease" or "date of this Lease" shall mean the

by Landlord.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

            This AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement")
entered into as of February 20, 2004, by and between Animas Corporation, a
Delaware corporation (the "Company"), and Katherine D. Crothall (the
"Executive").

            WHEREAS, the Company and the Executive entered into that certain
Employment Agreement dated January 1, 2002 and now wish to amend certain terms
of and restate that Agreement upon the terms and conditions set forth herein.

            NOW, THEREFORE, the parties hereto, intending to be legally bound,
hereby agree as follows:

            1.    Employment

                  1.1.  Position. The Company hereby agrees to continue to
employ the Executive as its President and Chief Executive Officer and the
Executive hereby accepts such employment and agrees to perform her duties and
responsibilities, in accordance with the following terms, conditions and
provisions.

                  1.2.  Employment Term. The term of the Executive's employment
under this Agreement shall commence on the date the Company's registration
statement on a Form S-1 is declared effective by the Securities and Exchange
Commission (the "Effective Date") and shall continue in effect through January
1, 2005 (the "Expiration Date"); provided, however, commencing on January 1,
2005 and on each January 1 thereafter, the Expiration Date shall automatically
be extended one additional year unless, not later than September 30 prior to
such January 1, either party shall give written notice to the other party that
the Expiration Date shall cease to be so extended (the "Original Term").
Notwithstanding the foregoing sentence, if a Change in Control occurs prior to
January 1, 2005, the term of the Executive's employment shall expire no earlier
than the second anniversary of the first day of the month following the month in
which the Change of Control occurs (the "Change of Control Term"), unless
terminated prior thereto in accordance with the applicable provision of Section
5. Notwithstanding any other provision of this Agreement to the contrary, this
Agreement shall immediately become null and void if the Effective Date does not
occur on or prior to June 30, 2004. Collectively the Original Term and the
Change of Control Term shall be referred to herein as the "Employment Term."

                  1.3.  Duties and Responsibilities. The Executive shall serve
as the Company's President and Chief Executive Officer and in such other senior
positions, if any, to which she may be elected by the Board of Directors of the
Company (the "Board") during the Employment Term. During the Employment Term,
the Executive shall perform all duties and accept all responsibilities incident
to, and not inconsistent with, such positions.

                  1.4.  Extent of Service. During the Employment Term, the
Executive agrees to use her best efforts to carry out her duties and
responsibilities under Section 1.3 hereof and, consistent with the other
provisions of this Agreement, to devote substantially all of her business time,
attention, and energy thereto, except to the extent required by the Executive's
outside board memberships and civic or charitable activities held on the date of
this Agreement.
<PAGE>
The Executive agrees not to become engaged in any additional business, civic or
charitable activity that, in the Board's reasonable judgment, is likely to
interfere materially with her ability to discharge her duties and
responsibilities to the Company.

                  1.5.  Base Salary. For all the services rendered by the
Executive hereunder, the Company shall pay the Executive a base salary at the
annual rate of $285,000 plus an automobile allowance of $1,100 per calendar
month ("Base Salary"), payable in installments at such times as the Company
customarily pays its other senior level officers (but in any event no less often
than monthly). The Executive's Base Salary shall be reviewed and may be
appropriately adjusted by the Board pursuant to its normal performance review
policies for senior level officers.

                  1.6.  Retirement and Benefit Coverages. The Executive shall be
eligible to participate in any pension plans, retirement plans and any health,
life, accident, general liability, directors and officers liability, or
disability insurance, sick leave or other benefit plans or programs made
available to other senior level officers of the Company as long as they are kept
in force by the Company ("Plans") and provided the Executive meets the
eligibility requirements and other terms, conditions and restrictions of the
respective Plans. In addition, the Executive shall be entitled to holiday,
vacation and sick leave in accordance with the Company's vacation, holiday and
pay for time not worked policies, as well as any other perquisites provided by
the Company to its senior level officers.

                  1.7.  Stock Options/Stock Awards/Benefits. In the event that
(i) the Executive's employment is terminated by the Company or a successor
entity pursuant to Section 5.2, (ii) the Executive resigns from the Company
pursuant to Section 5.3 or (iii) if the Executive's employment is terminated
during the six month period before or the twelve month period following a Change
of Control as defined in Section 6, then one hundred percent (100%) of any stock
option, restricted stock or other stock awards granted the Executive that have
not yet become exercisable or vested shall automatically accelerate and become
fully exercisable or vested on the effective date of such event and the
Executive shall become entitled to the payments set forth in Sections 5.2 or
5.3, as applicable. In addition, if a Change of Control (other than a Change of
Control within the meaning of Section 6.3(c) or Section 6.3(d) of this
Agreement) is consummated prior to December 31, 2006, then, (a) to the extent
that an option award that has been issued to Executive is subject to a vesting
and/or unexercisability period that extends longer than twenty-four (24) months
from such date, then that portion of the entire option award that is then
unvested and/or unexercisable and that would have become vested and/or
exercisable in the final twenty-four (24) months of such vesting and/or
unexercisability period shall become vested and immediately exercisable on the
date of a Change of Control and (b) to the extent that an option award that has
been issued to the Executive is subject to a vesting and/or unexercisability
period that is shorter then twenty-four (24) months from such date, then all of
the option award shall become vested and immediately exercisable on the date of
a Change of Control. Subject to the discretion of the Board, the Executive shall
be eligible to receive additional grants of stock options from time to time in
the future, on such terms and subject to such conditions as the Board shall
determine as of the date of any such grant.

                  1.8.  Life Insurance. During the Employment Term, the Company
shall maintain, under an arrangement satisfactory to the Company $3,000,000 of
life insurance on the

                                      -2-
<PAGE>
life of the Executive if available at reasonable commercial rates as determined
by the Board or if not available, for such lower amount as agreed to by the
Company and the Executive. The Executive shall have the right to designate the
beneficiary of such insurance policy. The Company may maintain term life
insurance, whole life insurance or such other form of insurance as it deems
appropriate.

                  1.9.  Incentive Programs. The Executive shall be entitled to
participate in any short-term or long-term incentive compensation programs
established by the Company for its senior level officers generally ("Incentive
Programs"). Payments under such Incentive Programs shall depend upon achievement
of certain business and individual performance targets specified and approved by
the Board; provided, however, that the Executive's "target opportunity" under
any such Incentive Program shall not be less than the highest level of target
opportunity of any other senior level Officer.

            2.    Confidential Information. The Executive acknowledges that, by
reason of her employment by and service to the Company before and during the
Employment Term, she has had and will continue to have access to certain
confidential and proprietary information relating to the Company's business,
which may include, but is not limited to, trade secrets as defined by
Pennsylvania Law, customer information, supplier information, cost and pricing
information, marketing and sales techniques, strategies and programs,
proprietary computer programs and software and financial information
(collectively referred to as "Confidential Information"). The Executive
acknowledges that such Confidential Information is a valuable and unique asset
of the Company and the Executive covenants that she will not at any time during
the Employment Term use any Confidential Information or divulge or disclose any
Confidential Information to any person, firm or corporation except in connection
with the Executive's good faith belief as to the proper performance of her
duties for the Company. The Executive also covenants that, for a period of three
(3) years after the termination of her employment, directly or indirectly, she
will not use any Confidential Information for any purpose or divulge or disclose
any Confidential Information to any person, firm or corporation, unless such
information is in the public domain through no fault of the Executive.
Notwithstanding the foregoing, if the Executive is required to disclose
Confidential Information by a court of law, by any governmental agency having
supervisory authority over the business of the Company or over the Executive or
by any administrative or legislative body (including a committee thereof) that
the Executive reasonably believes has apparent jurisdiction to order her to
divulge, disclose or make accessible such information, the Executive shall
inform the Company in writing promptly of such required disclosure and shall not
disclose any Confidential Information until steps taken by the Company to
preclude such disclosure have been ineffective or the Company authorizes
disclosure.

            3.    Non-Competition; Non-Solicitation.

                  3.1.  Non-Competition. The Executive agrees that:

                        (a)   During the Employment Term and for a period of two
(2) years thereafter, or, if longer, for the period during which the Executive
receives payments from the Company under Section 5.2, the Executive will not,
except with the prior written consent of the Board, directly or indirectly own,
manage, operate, join, control, finance or participate in the ownership,
management, operation, control or financing of, or be connected as an officer,

                                      -3-
<PAGE>
director, employee, partner, principal, agent, representative, consultant or
otherwise with, or use or permit her name to be used in connection with, any
business or enterprise that is engaged in a geographic area in which the Company
or any of its affiliates is operating or has documented plans to operate,
provided the Executive has knowledge of those plans, either during the
Employment Term or on the date the Executive's employment terminates, as
applicable, (whether or not such business is physically located within those
areas) (the "Geographic Area"), in any business that is directly competitive to
a business maintained by the Company or any of its affiliates or to a business
that the Company or any of its affiliates has documented plans to maintain,
provided that the Executive has knowledge of those plans, either during the
Employment Term or on the date the Executive's employment terminates, as
applicable ("Competing Business"). It is recognized by the Executive that the
business of the Company and its affiliates operates throughout the Geographic
Area and that the Executive is involved in such business throughout the
Geographic Area, and therefore, that more limited geographical limitations on
this non-competition covenant are not appropriate.

                        (b)   The foregoing restrictions shall not be construed
to prohibit the ownership by the Executive of less than five percent (5%) of any
class of securities of any corporation that is engaged in any of the foregoing
businesses having a class of securities registered pursuant to the Securities
Exchange Act of 1934 (the "Exchange Act"), provided that such ownership
represents a passive investment and that neither the Executive nor any group of
persons including the Executive in any way, either directly or indirectly,
manages or exercises control of any such corporation, guarantees any of its
financial obligations, otherwise takes any part in its business, other than
exercising her rights as a shareholder, or seeks to do any of the foregoing.

                  3.2.  Non-Solicitation. The Executive further covenants and
agrees that, during the Employment Term and for the period of two (2) years
thereafter, or, if longer, for the period during which the Executive receives
payments from the Company under Section 5.2, the Executive will not, without the
prior written consent of the Company, personally solicit for a Competing
Business any customer that was a customer of the Company or any of its
affiliates during the Employment Term or on the date on which the Executive's
employment terminates or any person who is a managerial or higher level employee
of the Company at the date the Executive's employment terminates. The foregoing
covenant of the Executive shall not apply to any person after twelve months have
elapsed subsequent to the date on which such person's employment by the Company
has terminated.

            4.    Equitable Relief.

                        4.1.  The Executive acknowledges and agrees that (i) the
restrictions contained in Sections 2 and 3 are reasonable and necessary to
protect and preserve the legitimate interest, properties, goodwill and business
of the Company, (ii) the Company would not have entered into this Agreement in
the absence of such restrictions and (iii) the Company will suffer irreparable
injury if the Executive breaches any of the provisions set forth in Sections 2
and 3. The Executive represents and acknowledges that (i) she has been advised
by the Company to consult her own legal counsel in respect of this Agreement,
and (ii) she has had full opportunity, prior to execution of this Agreement, to
review thoroughly this Agreement with her counsel.

                                      -4-
<PAGE>
                        4.2.  The Executive further acknowledges and agrees that
a breach of any of the restrictions in Sections 2 and 3 cannot be adequately
compensated by monetary damages. The Executive agrees that the Company shall be
entitled to seek preliminary injunctive relief, without the necessity of proving
actual damages. In the event that any of the provisions of Sections 2 or 3
hereof should ever be adjudicated to exceed the time, geographic, service, or
other limitations permitted by applicable law in any jurisdiction, it is the
intention of the parties that the provision shall be amended to the extent of
the maximum time, geographic, service, or other limitations permitted by
applicable law, that such amendment shall apply only within the jurisdiction of
the court that made such adjudication and that the provision otherwise be
enforced to the maximum extent permitted by law.

                        4.3.  The Executive irrevocably and unconditionally (i)
agrees that any suit, action or other legal proceeding arising out of this
Agreement, including, without limitation, any action commenced by the Company
for preliminary and permanent injunctive relief and other equitable relief, may
be brought in the United States District Court for the Eastern District of
Pennsylvania, or if such court does not have jurisdiction or will not accept
jurisdiction, in any court of general jurisdiction in Chester County,
Pennsylvania, (ii) consents to the non-exclusive jurisdiction of either such
court in any such suit, action or proceeding, and (iii) waives any objection
that the Executive may have to the laying of venue of any such suit, action or
proceeding in either such court. The Executive also irrevocably and
unconditionally consents to the service of any process, pleadings, notices or
other papers at the address set forth in the notice provisions of Section 12
hereof.

            5.    Termination.

                  5.1.  The Employment Term shall terminate upon the occurrence
of any one of the following events:

                        (a)   Disability. The Company may terminate the
Employment Term in compliance with applicable law, if the Executive is unable
substantially to perform the essential duties and responsibilities hereunder to
the full extent required by the Board by reason of mental or physical illness,
injury or any other cause for six consecutive months, or for more than nine
months in the aggregate during any period of twelve consecutive calendar months
(a "Disability"); provided, however, that the Company shall continue to pay the
Executive her Base Salary during such six month or twelve consecutive calendar
month period. At the date of such termination the Company shall prepare and
execute a release substantially in the form attached hereto as Annex 1, (the
"Release"), and present the Release for execution to the Executive, or the
Executive's representative should she lack capacity to execute the Release. Upon
execution of the Release by the Executive, or her personal representative, as
the case may be, the Executive shall be entitled to receive all payments and
benefits to the same extent and at the same time as specified in Section 5.2(b),
offset by any amounts the Executive receives under any long- term disability
program maintained by the Company. Otherwise, in the event of Disability, the
Company shall have no further liability or obligation to the Executive under
this Agreement except as set forth in the Release. In the event of any dispute
under this Section 5.1(a) and to the extent determined by the Board to be
job-related and consistent with business necessity, the Executive shall submit
to a physical examination by a licensed physician experienced in

                                      -5-
<PAGE>
disability examination selected by the Board and approved by the Executive, such
approval not to be unreasonably withheld.

                        (b)   Death. The Employment Term shall terminate on the
date of the Executive's death. In such event, the Company shall pay to the
Executive's executors, legal representatives or administrators, as applicable,
an amount equal to the installment of her Base Salary set forth in Section 1.5
hereof for the full month in which she dies, and all unreimbursed expenses and
unused vacation time. If the Executive dies while an employee of the Company,
the designated beneficiary, or if no such beneficiary has been designated, the
Executive's estate, shall be entitled to receive (i) the proceeds of the life
insurance policy described in Section 1.8 and (ii) a payment from the Company of
any other benefits in accordance with the terms of any Plan and Incentive
Programs of the Company, on the basis that the death of the Executive is
equivalent to termination without cause. Otherwise, the Company shall have no
further liability or obligation under this Agreement to her executors, legal
representatives, administrators, heirs or assigns or any other person claiming
under or through her.

                        (c)   Cause. The Company may terminate the Employment
Term at any time for "Cause" upon 30 days' written notice to the Executive, in
which event all payments under this Agreement shall cease, except for (i) Base
Salary to the extent already earned and a payment equal to any unreimbursed
expenses and unused vacation, which shall be paid in a single lump sum on the
day the Employment Term terminates, and (ii) any other benefits in accordance
with the terms of any applicable Plans and Incentive Programs of the Company.
For purposes of this Agreement, the Executive's employment may be terminated for
"cause" if (i) the Executive is convicted of a felony (ii) in the reasonable
determination of the Board, the Executive has committed an intentional act of
fraud, embezzlement, or theft in connection with the Executive's duties in the
course of her employment with the Company, (iii) in the reasonable determination
of the Board, the Executive has engaged in gross negligence in the course of her
employment with the Company that is materially harmful to the business of the
Company, or (iv) the Executive intentionally breached her obligations under this
Agreement, including inattention to or neglect of duties and shall not have
remedied such breach within 30 days after receiving written notice from the
Board specifying the details thereof and the act or failure to act by the
Executive is materially harmful to the business of the Company. For purposes of
this Agreement, an act or omission on the part of the Executive shall be deemed
"intentional" or "gross negligence" only if it was done by the Executive in bad
faith, not merely an error in judgment, and without reasonable belief that the
act or omission was in the best interest of the Company. In the event the
Executive disputes the existence of Cause in connection with a termination of
employment, no termination for Cause shall be effective in the absence of an
affirmative vote by the three fourths of the full Board (disregarding any
director who must abstain).

                  5.2.  Termination Without Cause.

                        (a)   The Company may terminate the Executive without
Cause, at any time, from the position in which she is employed hereunder (on
which date the Employment Term shall be deemed to have ended) upon not less than
30 days prior written notice to the Executive; provided, however, that,
commencing on the date of such notice, the

                                      -6-
<PAGE>
Executive shall be under no obligation to render any additional services to the
Company and shall be allowed to seek other employment. Upon such termination,
except as provided in Section 5.2(b) below, the Executive shall be entitled to
receive, as liquidated damages for the failure of the Company to continue to
employ the Executive (i) Base Salary to the extent already earned and a payment
equal to any unused vacation, unreimbursed expenses, which shall be paid in a
single lump sum on the day the Employment Term ends, and (ii) any other benefits
in accordance with the terms of any Plans and Incentive Programs of the Company.

                        (b)   Notwithstanding the foregoing, upon such
termination, the Company shall prepare and execute the Release and present the
Release to the Executive for execution. Upon the Executive's execution of the
Release and her agreement to be bound by the terms of and not rescind the
Release, she shall be entitled to receive, commencing on the eighth day
following execution of the Release, in lieu of the Company's obligations
described in Subsection (a) of this Section, which the Executive agrees to
waive, as liquidated damages for the failure of the Company to continue to
employ the Executive, (i) continuation for eighteen months of the Executive's
current Base Salary in accordance with Section 1.5 (without regard to the
Executive's removal), (ii) any other amounts earned, vested, or owing but not
yet paid under Section 1.5 through 1.9 above, (iii) a pro-rata portion of any
Incentive Programs to the extent that such amount would have been earned in
accordance with the terms of such Incentive Programs specified in Section 1.9
above for the then current fiscal year of the Company, without regard to a
requirement, if any, set forth in Incentive Programs of employment with the
Company at date of payment under such Incentive Programs (iv) a payment equal to
any unused vacation and unreimbursed expenses, (v) any other benefits in
accordance with the terms of any Plans and Incentive Programs of the Company
without regard to a requirement, if any, set forth in Plans or Incentive
Programs of employment with the Company at date of payment under such Plans or
Incentive Programs, and (vi) to the extent not provided in (E) directly above,
health insurance for the Executive and eligible family members and disability
insurance for the Executive, for a period of eighteen (18) months from the date
of termination pursuant to Section 5.2(a), each with coverage and at a cost
identical to that provided the Executive immediately prior to such termination.
Notwithstanding the foregoing, if the Company determines that it is unable to
provide the benefit set forth in (iv) or (v) above, the Company shall satisfy
its obligation under this Agreement through a cash payment of the amount
necessary to provide the benefit and the amount necessary to pay any federal,
state or local tax on such cash payment. Upon Termination Without Cause, the
Company shall have no liability or obligation to the Executive except as set
forth in Section 5.4 and in the Release.

                  5.3.  Constructive Termination Without Cause.

                        (a)   Resignation by the Executive for good reason
("Constructive Termination without Cause") shall mean a termination of the
Executive's employment at her initiative following the occurrence, without the
Executive's written consent, of(i) a material diminution in the Executive's
duties, responsibilities, authority or status, or a failure of the Executive to
have a position reporting directly to the Board, (ii) a reduction in any amount
of the Executive's Base Salary, (iii) the assignment to the Executive of duties
or responsibilities that are materially inconsistent with the duties,
responsibilities, authority, or status of her position as defined in Section 1.3
above or which materially impair the Executive's ability to function in her then
current position, (iv) the Executive's removal as a member of the

                                      -7-
<PAGE>
Board, or (v) a failure of the Company to comply with any of the material terms
of this Agreement; provided, however, that a termination of the Executive's
employment shall not constitute a Constructive Termination without Cause if the
Company's action is in response to actions taken by the Executive that
constitute Cause (as defined in Section 5.1(c) above).

                        (b)   In the event of a Constructive Termination Without
Cause, the Company shall prepare and execute the Release and present the Release
to the Executive for execution. Upon the Executive's execution of the Release
and agreement to be bound by and not rescind the terms of the Release, she shall
be entitled to receive all amounts and benefits to the same extent and at the
same time as specified in Section 5.2(b). In the event the Executive refuses to
execute and agree to be bound by the terms of the Release (or revokes the
Release), she shall receive only the amounts and benefits to the same extent and
at the same time as specified in Section 5.2(a).

                        (c)   Prior to resigning under this Section, the
Executive shall give written notice to the Board and offer a 30-day period for
the Company to cure. If no cure has been effected by the end of the applicable
cure period, the Executive may resign immediately. The Company may not terminate
the Executive pursuant to Section 5.1(c) or 5.2 subsequent to the date of the
written notice provided pursuant to this Section 5.3(c).

                  5.4.  Voluntary Termination. The Executive may voluntarily
terminate the Employment Term upon 30 days' prior written notice for any reason.
In such event, the Executive shall be entitled only to (i) Base Salary to the
extent already earned and a payment equal to any unused vacation, and
unreimbursed expense which shall be paid in a single lump sum on the day the
Employment Term terminates, and (ii) any other benefits in accordance with the
terms of any Plans and Incentive Programs of the Company. A voluntary
termination under this Section 5.4 shall not be deemed a breach of this
Agreement.

                  5.5.  Termination at End of Employment Term. Notwithstanding
Section 5.4, if the Executive's employment with the Company is terminated or not
renewed at the end of an Employment Term by the Company, the Company shall
prepare and execute the Release and present the Release to the Executive for
execution. Upon execution of the Release by the Executive, the Company shall pay
to the Executive as severance compensation the amounts described in Section
5.2(b), but with the Executive's Base Salary to continue under Section 5.2(b)(i)
for one year after termination of employment. The payments under this Section
5.5 shall be made in lieu of the payments described in Section 5.4, which the
Executive hereby agrees to waive. In the event the Executive refuses to execute
and agree to be bound by the terms of the Release (or revokes the Release), the
Executive shall receive only amounts and benefits specified in Section 5.4.

            6.    Change of Control.

                  6.1.  If a Change of Control (as defined in 6.3 below) occurs
during the Employment Term, any payment or distribution by the Company to or for
the benefit of the Executive pursuant to the terms of this Agreement or
otherwise shall be subject to the provisions of subsection 6.2 below.

                                      -8-
<PAGE>
                  6.2.  Notwithstanding anything in this Agreement to the
contrary, if it shall be determined that any payment or distribution by the
Company to or for the benefit of the Executive pursuant to the terms of this
Agreement or otherwise (a "Payment") would constitute an "excess parachute
payment" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), and that it would be economically advantageous to
the Executive to reduce the Payment to avoid or reduce the taxation of excess
parachute payments under Section 4999 of the Code, the aggregate present value
of the amounts payable or distributable to or for the benefit of the Executive
pursuant to this Agreement (such payments or distributions pursuant to this
Agreement are hereinafter referred to as "Agreement Payments") shall be reduced
(but not below zero) to the Reduced Amount. The "Reduced Amount" shall be an
amount expressed in present value that maximizes the aggregate present value of
Agreement Payments without causing any Payment to be subject to taxation under
Section 4999 of the Code. For purposes of this Section 6, present value shall be
determined in accordance with Section 280G(d)(4) of the Code. The calculations
under this Section 6.2 shall be made as follows:

                        (a)   All determinations to be made under this Section
6.2 shall be made by the Company's independent public accounting firm as in
effect immediately prior to the Change of Control (the "Accounting Firm"), which
firm shall provide its determinations and any supporting calculations to the
Company and Chief Executive Officer within 10 days of the event that gives rise
to the "excess parachute payment." Any such determination by the Accounting Firm
shall be binding upon the Company and the Executive. The Executive shall in her
sole discretion determine which and how much of the Agreement Payments shall be
eliminated or reduced consistent with the requirements of this Section 6.2.
Within five days after the Executive's determination, the Company shall pay (or
cause to be paid) or distribute (or cause to be distributed) to or for the
benefit of the Executive such amounts as are then due to the Executive under
this Agreement. As a result of the uncertainty in the application of Section
280G of the Code at the time of the initial determination by the Accounting Firm
hereunder, it is possible that Agreement Payments will have been made by the
Company that should not have been made ("Overpayment") or that additional
Agreement Payments that have not been made by the Company could have been made
("Underpayment"), in each case, consistent with the calculations required to be
made hereunder. Within two years after the event that gives rise to the "excess
parachute payment," the Accounting Firm shall review the determination made by
it pursuant to the preceding paragraph. If the Accounting Firm determines that
an Overpayment has been made, any such Overpayment shall be promptly repaid by
the Executive to the Company; provided, however, that no amount shall be
repayable by the Executive to the Company if and to the extent such repayment
would not reduce the amount which is subject to taxation under Section 4999 of
the Code. In the event that the Accounting Firm determines that an Underpayment
has occurred, any such Underpayment shall be promptly paid by the Company to or
for the benefit of the Executive.

                        (b)   All of the fees and expenses of the Accounting
Firm in performing the determinations referred to in subsection (a) above shall
be borne solely by the Company. The Company agrees to indemnify and hold
harmless the Accounting Firm from any and all claims, damages and expenses
resulting from or relating to its determinations pursuant to subsections (a)
above, except for claims, damages or expenses resulting from the gross
negligence or willful misconduct of the Accounting Firm.

                                      -9-
<PAGE>
                        (c)   The limitations of this Section 6.2 shall only
apply if payments under this Agreement are subject to Section 280G at the time
of the Change of Control. If payments under this Agreement would not be subject
to Section 280G if the shareholders of the Company approved the payments, the
Company shall use its commercially reasonable efforts to procure the necessary
shareholder approval of the payments in a timely manner. If the shareholders
approve the payments so that Section 280G does not apply, the Company shall make
payments under this Agreement without regard to this Section 6.2.

                  6.3.  A "Change of Control" shall be deemed to have occurred
if the event set forth in any one of the following paragraphs shall have
occurred:

                        (a)   Any "person" (as such term is used in Sections
13(d) and 14(d) of the Exchange Act other than a person who is a shareholder of
the Company as of the effective date of this Agreement) is or becomes a
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing more than 50% of the
combined voting power of the then outstanding securities of the Company, as
determined by the Board of Directors of the Company or

                        (b)   The closing of a merger, consolidation or other
form of business combination of the Company, or any direct or indirect
subsidiary of the Company, with another corporation and the shareholders of the
Company, immediately prior to such transaction, will not beneficially own,
immediately after such transaction, shares of the Company or the surviving
entity or any parent thereof, entitling the shareholders of the Company to vote
more than 50% of all shares of the Company, or the surviving entity or any
parent thereof which would be entitled in the election of directors (without
consideration of the rights of any class of stock to elect directors by a
separate class vote),

                        (c)   The sale or other disposition of all or
substantially all of the assets of the Company, or

                        (d)   A liquidation or dissolution of the Company.

                        (e)   Individuals who are Continuing Directors cease to
constitute a majority of the members of the Board. "Continuing Directors" for
this purpose being the members of the Board on the date of adoption of this
Agreement, provided that any person becoming a member of the Board subsequent to
such date whose election or nomination for election was supported by two-thirds
of the Directors who then comprised the Continuing Directors shall be considered
to be a Continuing Director.

            7.    Survivorship. The respective rights and obligations of the
parties hereunder shall survive any termination of the Executive's employment
and the Employment Term to the extent necessary to the intended preservation of
such rights and obligations.

            8.    Settlement of Disputes; Arbitration; Expenses. All claims by
the Executive for benefits under this Agreement shall be directed to and
determined by the Board and shall be in writing. Any denial by the Board of a
claim for benefits under this Agreement shall be delivered to the Executive in
writing and shall set forth the specific reasons for the denial and the specific
provisions of this Agreement relied upon. The Board shall afford a reasonable

                                      -10-
<PAGE>
opportunity for a review of the decision denying a claim and shall further allow
to appeal to the Board a decision of the Board within sixty (60) days after
notification by the Board that the Executive's claim has been denied. Any
further dispute under the provisions of this Agreement (other than a dispute in
which the primary relief sought is an equitable remedy such as an injunction)
shall be settled by arbitration in the City of Philadelphia, Pennsylvania in
accordance with the National Rules for the Resolution of Employment Disputes
then in effect of the American Arbitration Association, before a panel of three
arbitrators, two of whom shall be selected by the Company and the Executive,
respectively, and the third of whom shall be selected by the other two
arbitrators. Any award entered by the arbitrators shall be final, binding and
nonappealable and judgment may be entered thereon by either party in accordance
with applicable law in any court of competent jurisdiction. This arbitration
provision shall be specifically enforceable. The arbitrators shall have no
authority to modify any provision of this Agreement or to award a remedy for a
dispute involving this Agreement other than a benefit specifically provided
under or by virtue of the Agreement. If the Executive prevails on any material
issue which is the subject of such arbitration or lawsuit, the Company shall be
responsible for all of the fees of the American Arbitration Association and the
arbitrators and any expenses relating to the conduct of the arbitration as well
as the Executive's reasonable legal fees and expenses. The arbitrators shall, in
any other event, determine who shall pay the Executive's legal fees and
expenses.

            9.    No Attachment. Except as required by law, no right to receive
payments under this Agreement shall be subject to anticipation, commutation,
alienation, sale, assignment, encumbrance, charge, pledge, or hypothecation or
to execution, attachment, levy, or similar process or assignment by operation of
law, and any attempt, voluntary or involuntary, to effect any such action shall
be null, void and of no effect; provided, however, that nothing in this Section
shall preclude the assumption of such rights by executors, administrators or
other legal representatives of the Executive or her estate and their assigning
any rights hereunder to the person or persons entitled thereto.

            10.   Source of Payment. All payments provided for under this
Agreement shall be paid in cash from the general funds of the Company. The
Company shall not be required to establish a special or separate fund or other
segregation of assets to assure such payments, and, if the Company shall make
any investments to aid it in meeting its obligations hereunder, the Executive
shall have no right, title or interest whatever in or to any such investments
except as may otherwise be expressly provided in a separate written instrument
relating to such investments. Nothing contained in this Agreement, and no action
taken pursuant to its provisions, shall create or be construed to create a trust
of any kind, or a fiduciary relationship, between the Company and the Executive
or any other person. To the extent that any person acquires a right to receive
payments from the Company hereunder, such right, without prejudice to rights
which employees may have, shall be no greater than the right of an unsecured
creditor of the Company.

            11.   Notices. All notices and other communications required or
permitted hereunder or necessary or convenient in connection herewith shall be
in writing and shall be deemed to have been given when hand delivered or mailed
by registered or certified mail, as follows (provided that notice of change of
address shall be deemed given only when received):

            If to the Company, to:

            Animas Corporation
            590 Lancaster Avenue
            Frazer, PA 19355

            If to the Executive, to the address on file with the Company:

or to such other names or addresses as the Company or the Executive, as the case
may be, shall designate by notice to each other person entitled to receive
notices in the manner specified in this Section.

            12.   Contents of Agreement; Amendment and Assignment.

                  12.1. This Agreement supersedes all prior agreements and sets
forth the entire understanding between the parties hereto with respect to the
employment of the Executive by the Company (including, without limitation, that
certain Employment Agreement by and between the Company and Executive dated
January 1, 2002) and cannot be changed, modified, extended or terminated except
as provided herein or upon written amendment approved by the Company and
executed on its behalf by a duly authorized officer and by the Executive. This
Agreement does not amend or modify the provisions of any Plans or Incentive
Programs in which the Executive participates or is eligible to participate
except as set forth in Sections 1.7 and 5.2(b)(iii) and (v) hereof.

                  12.2. All of the terms and provisions of this Agreement shall
be binding upon and inure to the benefit of and be enforceable by the respective
heirs, executors, administrators, legal representatives, successors and assigns
of the parties hereto, except that the duties and responsibilities of the
Executive hereunder are of a personal nature and shall not be assignable or
delegatable in whole or in part by the Executive. The Company shall require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization or otherwise) to all or substantially all of the business or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the extent the Company would be required to perform if no such
succession had taken place.

            13.   Severability. If any provision of this Agreement or
application thereof to anyone or under any circumstances is adjudicated to be
invalid or unenforceable in any jurisdiction, such invalidity or unenforceabiity
shall not affect any other provision or application of this Agreement which can
be given effect without the invalid or unenforceable provision or application
and shall not invalidate or render unenforceable such provision or application
in any other jurisdiction. If any provision is held void, invalid or
unenforceable with respect to particular circumstances, it shall nevertheless
remain in full force and effect in all other circumstances.

            14.   Remedies Cumulative; No Waiver. No remedy conferred upon a
party by this Agreement is intended to be exclusive of any other remedy, and
each and every such remedy shall be cumulative and shall be in addition to any
other remedy given hereunder or now or hereafter existing at law or in equity.
No delay or omission by a party in exercising any right,

                                      -12-
<PAGE>
remedy or power hereunder or existing at law or in equity shall be construed as
a waiver thereof, and any such right, remedy or power may be exercised by such
party from time to time and as often as may be deemed expedient or necessary by
such party in its sole discretion.

            15.   Beneficiaries/References. The Executive shall be entitled, to
the extent permitted under any applicable law, to select and change a
beneficiary or beneficiaries to receive any compensation or benefit payable
hereunder following the Executive's death by giving the Company written notice
thereof. In the event of the Executive's death or a judicial determination of
her incompetence, references in this Agreement to the Executive shall be deemed,
where appropriate, to refer to her beneficiary, estate or other legal

            16.   Miscellaneous. All section headings used in this Agreement are
for convenience only. This Agreement may be executed in counterparts, each of
which is an original. It shall not be necessary in making proof of this
Agreement or any counterpart hereof to produce or account for any of the other
counterparts.

            17.   Withholding. The Company may withhold from any payments under
this Agreement all federal, state and local taxes as the Company is required to
withhold pursuant to any law or governmental rule or regulation. The Executive
shall bear all expense of, and be solely responsible for, all federal, state and
local taxes due with respect to any payment received hereunder except as
otherwise provided with respect to her restricted stock award.

            18.   Governing Law. This Agreement shall be governed by and
interpreted under the laws of the Commonwealth of Pennsylvania without giving
effect to any conflict of laws provisions.

            IN WITNESS WHEREOF, the undersigned, intending to be legally bound,
have executed this Agreement as of the date first above written.
