REMEDIES UPON TENANT'S DEFAULT

     19th:     If there should occur any default on the part of the Tenant in
the performance of any conditions and covenants herein contained, or if during
the term hereof the premises or any part thereof shall be or become abandoned or
deserted, vacated or vacant, or should the Tenant be evicted by summary
proceedings or otherwise, the Landlord , in addition to any other remedies
herein contained or as may be permitted by law, may, without being liable for
prosecution therefor, or for damages, re-enter the said premises and the same

rents as may be in arrears and also the rents as may accrue subsequent to the
re-entry by the Landlord, to the extent of the difference between the rents
reserved hereunder and the rents, if any, received by the Landlord during the

for the benefit of creditors [SEE ADDENDUM A-36], or if this lease or the estate
of the Tenant hereunder shall pass to another by virtue of any court
proceedings, writ of execution, levy, sale, or by operation of law, the Landlord
may, if the Landlord so elects, at any time thereafter, terminate this lease and
the term hereof, upon giving to the Tenant or to any trustee, receiver, assignee
or other person in charge of or acting as custodian of the assets or property of
the Tenant, five days notice in writing, of the Landlord's intention so to do.
Upon the giving of such notice, this lease and the term hereof shall end on the
date fixed in such notice as if the said date was the date originally fixed in
this lease for the expiration hereof; and the Landlord shall have the right to
remove all persons, goods, fixtures and chattels therefrom, without liability
for damages.

NON-LIABILITY OF LANDLORD

any remedy herein conferred or the acceptance by the Landlord of any installment
of rent after any breach by Tenant, in any one or more instances, shall not be
construed or deemed to be a waiver or a relinquishment for the future by the
Landlord of any such conditions and covenants, options, elections or remedies,
but the same shall continue in full force and effect.

NON-PERFORMANCE BY LANDLORD

     23rd:     This lease and the obligation of the Tenant to pay the rent

affected, curtailed, impaired or excused because of the Landlord's inability to
supply any service or material called for herein, by reason of any rule, order,
regulation or preemption by any governmental entity, authority, department,
agency or subdivision or for any delay which may arise by reason of negotiations
for the adjustment of any fire or other casualty loss or because of strikes or
other labor trouble or for any cause beyond the control of the Landlord. [See
Addendum A - 38]

$32,252.00 as security for the payment of the rent hereunder and the full and
faithful performance by the Tenant of the covenants and conditions on the part

interest, after the expiration of the term hereof, provided that the Tenant [See
Addendum A - 44]. During the term hereof, the Landlord may, if the Landlord so
elects, have recourse to such security, to make good any default by the Tenant,
in which event the Tenant shall, on demand, promptly restore said security to

repayment thereof as herein provided, and the assignor shall be deemed to be
released by the Tenant from all liability to return such security. This
provision shall be applicable to every alienation or change in title and shall
in no wise be deemed to permit the Landlord to retain the security after
termination of the Landlord's ownership of the reversion or title. The Tenant
shall not mortgage, encumber or assign said security without the written consent
of the Landlord.

        any repairs or replacements (i) which are required as the result of the
        negligence or willful misconduct of Landlord, its agents, employees,
        representatives or contractors, or the failure of Landlord to perform
        its obligations under this Lease, or (ii) which would constitute a
        Capital Improvement (as defined in Section 7 below), all of which
        repairs and replacements shall be made by Landlord at Landlord's sole
        cost and expense.

5.      Notwithstanding anything to the contrary contained herein, Landlord
        covenants and agrees that it will, at Landlord's sole cost and expense,

        practicable, interfering with the conduct of Tenant's business. If
        during such repairs and replacements the premises are wholly or
        partially unsuitable for their use as provided in this Lease, there

        replacements (i) relate to any portion of the premises the maintenance

        Improvements") under generally accepted accounting principles
        consistently applied ("GAAP").

 21.    Notwithstanding anything to the contrary contained herein, Tenant shall
        have the right, without Landlord's consent, to assign or sublet this
        Lease (a) to a parent, subsidiary or affiliate of Tenant, (b) in
        connection with a merger, consolidation or combination or (c) in
        connection with a sale of substantially of all of the assets of Tenant.

22.     provided the holder thereof enters into an agreement with Tenant in
        recordable form, binding upon the successors and assigns of the parties
        thereto, by the terms of which such holder agrees not to disturb the
        possession and other rights of Tenant under or pursuant to this Lease
        during the Term, as the same may be extended, so long as Tenant is not
        in default hereunder beyond the expiration of all applicable notice and
        cure periods, and in the event of acquisition of title, or coming into
        possession, by said holder through foreclosure proceedings or otherwise,
        to accept Tenant as tenant of the premises under the terms and
        conditions of this Lease, and to assume and perform all of Landlord's
        obligations hereunder.

23.     If at the time of execution of this Lease there shall be any mortgage
        encumbering the premises, Landlord shall obtain and deliver to Tenant,
        within thirty (30) days thereafter, a non-disturbance agreement with
        respect to such mortgage in form reasonably acceptable to Tenant. In the
        event that Landlord shall not have delivered such non-disturbance
        agreement prior to the expiration of the aforesaid thirty (30)-day
        period, Tenant shall have the continuing right to terminate this Lease
        on thirty (30) days' prior notice to Landlord and, upon the expiration
        of said thirty (30)-day notice period, if such non-disturbance agreement
        shall not have been delivered to Tenant, this Lease shall terminate as
        if such date were herein fixed as the expiration date hereof.

24.     ; provided that Tenant shall have the right to receive a separate award
        with respect to its personal property and relocation costs.

25.     If the premises, or such portion thereof as to render the balance (if
        reconstructed to the maximum extent practicable) unsuitable for Tenant's
        purposes, shall be taken by condemnation or right of eminent domain
        (including a temporary taking in excess of one hundred eighty (180)
        days), Tenant shall have the right to terminate this Lease by notice to
        Landlord within thirty (30) days after Tenant has been deprived of
        possession. Notwithstanding anything to the contrary contained herein,
        if Landlord shall fail to restore the remainder of the premises as
        nearly equivalent as practicable to their condition immediately prior to
        the taking within one hundred eighty (180) days from the date that
        possession of the portion of the premises so taken is delivered to the
        condemning authority (regardless of force majeure), then, in such event,
        Tenant may terminate this Lease by ten (10) days' prior written notice
        to Landlord given no later than thirty (30) days after the expiration of
        the aforesaid one hundred eighty (180)-day period. In the case of a
        taking that permanently reduces the area of the premises, a just
        proportion of the base rent and additional rent hereunder shall be
        abated for the remainder of the Term, as the same may be extended.

                                       3
<PAGE>

26.     and the base rent shall be abated in an equitable manner based upon the
        nature and extent of the damage to the premises until completion of such
        repairs by Landlord.

27.     In the event that the premises are damaged to the extent that thirty
        percent (30%) or more of the floor area thereof is rendered
        untenantable, Tenant shall have the right to terminate this Lease upon
        ten (10) days' prior written notice given to Landlord no later than
        thirty (30) days after the date of occurrence of such damage.
        Notwithstanding anything to the contrary contained herein, if Landlord
        shall fail either to complete the restoration and repair of the
        premises, or to restore the same as nearly equivalent as practicable to
        their condition immediately prior to the damage or destruction, within
        one hundred eighty (180) days from the date of occurrence of the damage
        or destruction (regardless of force majeure), then, in either such
        event, Tenant may terminate this Lease by ten (10) days' prior written
        notice to Landlord given no later than thirty (30) days after the
        expiration of the aforesaid one hundred eighty (180)-day period.

28.     if Tenant has not commenced to remedy such failure within five (5) days
        after written notice thereof by Landlord to Tenant, or if Tenant
        thereafter fails to diligently prosecute such remedy to completion,

29.     and upon no less than twenty-four (24) hours' prior notice to Tenant
        (except in the event of emergency in which case no notice will be
        required)

30.     Except in the event of emergency, Landlord shall be accompanied by a
        representative of Tenant at all times while entering the premises, which
        representative Tenant agrees to make available promptly upon request.

31.     during the last six (6) months of the Term, as the same may be extended,

32.     reasonably

33.     expiration of said fifteen (15)-day period

34.     unless Tenant, prior to the expiration of said fifteen (15)-day period,
        shall provide Landlord with evidence of Tenant's ability to insure the
        premises under a policy of "All Risk" insurance, in an amount equal to
        the full replacement value of the premises, issued by a reputable
        insurance company licensed to do business in the state in which the
        premises are located and reasonably acceptable to Landlord. Such
        insurance shall show Landlord as a named insured with respect to the
        real property.

35.     Landlord shall use reasonable efforts to mitigate its damages hereunder.

36.     and, with respect to proceedings initiated against Tenant, are not
        discharged within sixty (60) days thereafter

37.     except to the extent such damage or injury is caused by the negligence
        or willful misconduct of Landlord, its agents, employees,
        representatives or contractors.

38.     Tenant shall not be deemed to be in default under this Lease if
        prevented from performing any obligation hereunder for any reason beyond
        its reasonable control, including without limitation Acts of God, war,
        civil commotion, fire, flood or casualty, labor difficulties, shortages
        of or inability to obtain labor, materials or equipment, governmental
        regulations or restrictions, or unusually severe weather. It is agreed
        that financial inability shall not be a matter beyond Tenant's
        reasonable control for purposes of this Section.

                               TO LEASE AGREEMENT
                               DATED AUGUST , 1995
                                 BY AND BETWEEN
                            IRVING BROWN ("LANDLORD")
                                       AND
                 INTERNATIONAL TECHNIDYNE CORPORATION ("TENANT")

        Notwithstanding the provisions of the above-referenced Lease Agreement
(the "Lease"), the following new Sections 33 through 47 are hereby added to and
made a part of the Lease:

        33RD: In the event that Tenant fails to make any payment of monthly base
rent, on or before the tenth (10th) day of the month in which the same is due,
Tenant shall, from and after the second such occurrence, pay to Landlord a late
charge equal to five percent (5%) of such monthly installment.

        34TH: Any consent or approval of Landlord required under this Lease
shall not be unreasonably withheld, conditioned or delayed.

        35TH: Prior to the Commencement Date, Landlord shall construct, at
Landlord's sole cost and expense, the demising walls and other improvements
shown on Schedule A attached hereto and incorporated herein by this reference
("Landlord's Work") in order to separate the premises demised hereunder from the
balance of the Building (which balance consists of approximately 5,260 square
feet) currently occupied by ISA. Upon completion of Landlord's Work, Tenant's
premises shall have separate electric, gas, water and sewer meters and shall be
physically separated from the balance of the Building in a secure manner, having
their own entrance from the parking lot and their own bathrooms. It is the
intent of the parties hereto that the premises demised hereunder to Tenant shall
be self-contained and have no access to or from any other tenant's space in the
Building.

        36TH: Upon paying the security deposit and signing this Lease, Tenant
shall have the right to enter the Building on October 1, 1995, in order to
commence, at Tenant's sole cost and expense, the construction of its leasehold
improvements in the premises. Tenant shall have access to the premises from
October 1, 1995, through October 31, 1995, between the hours of 8:00 a.m. and
5:00 p.m., Monday through Friday, excluding holidays, for the purpose of such
construction. Tenant shall notify a person to be designated by Landlord of
Tenant's intent to enter the premises. Permission to enter during this
construction period shall not be unreasonably withheld, conditioned or delayed.
Tenant shall have the right to occupy the premises and commence its business
operations therein on November 1, 1995. Tenant and Landlord understand that ISA
currently occupies and will continue to occupy the premises covered under this
Lease until October 31, 1995. Landlord and ISA will cooperate with Tenant so
that the transition period will run smoothly and so as to minimize inconvenience
to any party involved. Tenant shall pay to Landlord the sum of $12,500.00 for
such occupancy for the month of November, 1995. Tenant shall pay no base rental
or other charges for its occupancy of the premises for the month of

                                       1
<PAGE>
December, 1995. As of the Commencement Date, all base rental and other charges
hereunder shall be payable in accordance with the terms and conditions of this
Lease.

        37TH: Commencing upon the Commencement Date hereunder, Tenant shall pay
to Landlord, in twelve (12) equal monthly installments together with the base
rental, an amount equal to 82.169% ("Tenant's share" or "Tenant's pro rata
share") of the following charges:

        1. Real estate taxes on the Building and Land.

        2. Commercial liability insurance and extended coverage "All Risk"
        insurance, in an amount equal to the replacement cost of the Building,
        and any other insurance that Landlord reasonably deems necessary for the
        protection of the Building and Land.

        3. Maintenance and repairs to the common areas serving the Building,
        including without limitation landscaping, snow removal and clean-up of
        the parking lot (the "Common Area Expenses").

        4. Any inspections and maintenance to the fire sprinkler systems.

        38TH: Except to the extent expressly otherwise provided herein, Tenant
shall, at its sole cost and expense, maintain and repair the non-structural
interior portions of the premises, including without limitation the air
conditioning and heating units exclusively serving the premises, and all
electrical wiring and plumbing lines after the point that they enter the
premises. Landlord warrants that, as of the Commencement Date, all of the above
systems shall be in good working order and repair.

        39TH: Tenant shall have the option to renew this Lease for an additional
three (3)-year period, beginning on July 1, 1999, and ending on June 30, 2002.
Tenant shall have the right to exercise such option to renew by written notice
to Landlord given on or before June 30, 1998. If Tenant fails to so notify
Landlord, Tenant shall be deemed to have waived its option. All terms and
conditions of this Lease shall remain the same during the option period except
that the annual base rental shall be increased by an amount equal to three
percent (3%) of the previous year's base rental. This increase shall take place
each and every January 1st during the option period, it being understood and
agreed that the base rental for the period commencing on July 1, 1999 and
continuing through and including December 31, 1999, shall be paid at the annual
rate in effect at the time of expiration of the original Term of this Lease.
Notwithstanding anything to the contrary contained herein, in no event shall
Tenant be obligated to make any payment of base rental hereunder prior to the
substantial completion of Landlord's Work. The term "substantial completion" for
purposes of this Section shall mean completion of Landlord's Work in accordance
with Schedule A hereto, with the exception of minor punchlist items that can be
fully completed within ten (10) working days without material interference with
Tenant's use and occupancy of the premises as permitted hereunder.

                                       2
<PAGE>
        40TH: The term "real estate taxes" for purposes of this Lease shall mean
all ad valorem real estate taxes payable with respect to the building in which
the premises are located (the "Building") and the land on which the Building is
situated (the "Land"). The term "real estate taxes" shall also include such
taxes as may be imposed in lieu of ad valorem real estate taxes; provided,
however, that in no event shall Tenant be responsible for payment of any
inheritance, estate, succession, transfer or gift tax imposed on Landlord or any
income tax or any other like tax which is measured in any manner by the income
or profit of Landlord. Within thirty (30) days after the end of each full or
partial tax year falling within the Term of this Lease, as the same may be
extended, Landlord shall deliver to Tenant (i) a copy of the paid tax bill(s)
relating to such tax year and (ii) Landlord's computation of Tenant's share of
the taxes covered by such bill(s). If the tax payments previously made by Tenant
with respect to such tax year either exceed or are less than Tenant's share of
the actual taxes evidenced by such bill(s), the difference shall be paid by or
reimbursed to Tenant, as appropriate, within fifteen (15) days after Tenant's
receipt of such bill(s). Tenant shall not, in any event, be liable for any
interest or penalty charge payable by Landlord with respect to any tax bill
unless such charge is the result of Tenant's failure to make its tax payments to
Landlord hereunder in a timely manner in accordance with the provisions of this
Section. A fair and equitable adjustment shall be made with respect to any tax
payments due from Tenant to Landlord in connection with the first and last
periods of the Term of this Lease, as the same may be extended, since said
periods may not coincide with the tax years involved. If Landlord shall obtain
any abatement, refund or rebate in real estate taxes applicable to the Building
or Land, Landlord shall promptly forward to Tenant its pro rata share of said
abatement, refund or rebate, less Tenant's pro rata share of the cost and
expense of obtaining the same. Notwithstanding anything to the contrary
contained herein, Landlord shall elect to pay in installments, over the longest
period allowed by the applicable taxing authority, any betterment or special
assessment included within the definition of real estate taxes hereunder, and
Tenant shall only be obligated to pay its pro rata share of those installments
which are allocable to the Term of this Lease, as the same may be extended.

        41ST: Landlord agrees to maintain in good condition and repair the
sprinkler system for the Building, to keep the parking areas serving the
Building well-lighted and to perform all landscaping of the Land and all
maintenance of, and snow and ice removal from, all paved areas of the Land, all
in such manner as shall be in keeping with first-class industrial park practices
and, to the extent practicable, without interfering with the conduct of Tenant's
business. Tenant's share of the Common Area Expenses shall be prorated with
respect to any partial year at the commencement or expiration (or earlier
termination) of the Term of this Lease, as the same may be extended. Within
sixty (60) days after the end of each calendar year, Landlord shall provide to
Tenant a detailed statement of the Common Area Expenses for such year in form
and with accompanying back-up documentation reasonably satisfactory to Tenant.
If the payments previously made by Tenant with respect to such year either
exceed or are less than Tenant's share of the actual Common Area Expenses as
evidenced by such statement, the difference shall be paid by or reimbursed to
Tenant, as appropriate, within fifteen (15) days after Tenant's receipt of said
statement. In no event shall any of the following be included within the
definition of Common Area Expenses: Original costs of acquisition of land or
constructions, the cost of any Capital Improvement (as defined in Section 7
above), administrative costs, management fees, real estate taxes, depreciation,
interest amortization, refinancing costs, overhead and profit, any item for

                                       3
<PAGE>
which Landlord is otherwise compensated or which is otherwise payable to
Landlord pursuant to the terms of this Lease, the cost of redecorating,
subdividing or otherwise preparing another tenant's space, interest or penalties
resulting from late payments by Landlord and any other cost benefiting specific
tenant(s) and not all tenants generally. Tenant shall have the right from time
to time, by its accountants or representatives, to inspect and examine all of
Landlord's records (including without limitation supporting data) relating to
the calculation of Common Area Expenses payable by Tenant hereunder, as well as
to request and receive reasonable invoice support with respect to the same.
Landlord shall retain such records for at least two (2) years. In the event that
any such inspection discloses that Tenant has paid an amount in excess of
Tenant's pro rata share, Landlord shall refund such excess to Tenant promptly
upon demand. In addition, in the event that any such inspection discloses that
Landlord has charged Tenant in excess of three percent (3%) more than the amount
properly chargeable to Tenant, Landlord shall reimburse to Tenant the reasonable
costs of such inspection promptly upon demand.

        42ND: Notwithstanding anything to the contrary contained herein, Tenant
may, but shall not be obligated to, cure, at any time following ten (10) days'
prior written notice to Landlord (except in cases of emergency when no notice
shall be required), any default by Landlord under this Lease, and Tenant may
reimburse itself for the cost thereof out of payments thereafter accruing
hereunder (with any unreimbursed balance remaining upon the expiration or
earlier termination of this Lease to be promptly paid by Landlord to Tenant).

        43RD: If any action at law or in equity is brought to enforce or
interpret the provisions of this Lease, the prevailing party in such action
shall be entitled to reimbursement of the reasonable attorneys' fees and
disbursements and court costs incurred by said prevailing party in connection
with such action.

        44TH: Landlord agrees to indemnify, defend and hold harmless Tenant, its
parent, subsidiaries and affiliates, and their respective officers, directors,
shareholders and employees, from and against any and all liabilities, losses,
damages, suits, actions, causes of action, costs, expenses (including without
limitation reasonable attorneys' fees and disbursements and court costs),
penalties, fines, demands, judgments, claims or liens (including without
limitation liens or claims imposed under any so-called "Superfund" or other
environmental legislation) arising from or in connection with the presence at
the time of Tenant's taking possession of the Premises of Hazardous Materials
(as hereinafter defined) on, or the subsequent removal thereof from, the
Premises.

        Tenant agrees to indemnify, defend and hold harmless Landlord from and
against any and all liabilities, losses, damages, suits, actions, causes of
action, costs, expenses (including without limitation reasonable attorneys' fees
and disbursements and court costs), penalties, fines, demands, judgments, claims
or liens (including without limitation liens or claims imposed under any
so-called "Superfund" or other environmental legislation) arising from or in
connection with the use, storage, release or discharge by Tenant of Hazardous
Materials on, or the subsequent removal thereof from, the Premises.

                                       4
<PAGE>
        For purposes of this Section, the term "Hazardous Materials" shall
include without limitation any petroleum product, any flammable, explosive or
radioactive material, or any hazardous or toxic waste, substance or material,
including without limitation substances defined as "hazardous substances",
"hazardous materials," "solid waste" or "toxic substances" under any applicable
laws relating to hazardous or toxic materials and substances, air pollution
(including noise and odors), water pollution, liquid and solid waste,
pesticides, drinking water, community and employee health, environmental land
use management, stormwater, sediment control, nuisances, radiation, wetlands,
endangered species, environmental permitting and petroleum products, which laws

Act, as amended; the Emergency Planning and Community Right-to-Know Act, as
amended; the Occupational Safety and Health Act, as amended; comparable state
laws; and all rules and regulations promulgated pursuant to such laws and
ordinances.

        The provisions of this Section shall survive the expiration or earlier
termination of the Term of this Lease, as the same may be extended.

        45TH: So long as Tenant shall be contesting, in good faith and by
appropriate legal proceedings, the validity of any law, ordinance, order or
regulation, compliance with which is the responsibility of Tenant under this
Lease, Tenant may defer compliance with the same provided Tenant first gives
Landlord assurance reasonably satisfactory to Landlord against any loss, cost or
expense on account thereof.

        46TH: This Lease shall be governed by and construed in accordance with
the laws of the State of New Jersey. No delay or omission on the part of either
party to this Lease in requiring performance by the other party or in exercising
any right hereunder shall operate as a waiver of any provisions hereof or of any
right hereunder, and the waiver, omission or delay in requiring performance or
exercising any right hereunder on any one occasion shall not be construed as a
bar to or waiver of such performance or right on any future occasion. Any and
all rights and remedies which either party may have under this Lease, at law or
in equity, shall be cumulative and shall not be deemed inconsistent with each
other, and any two or more of all such rights and remedies may be exercised at
the same time insofar as permitted by law. The individuals executing this Lease
hereby represent and warrant that they are empowered and duly authorized to so
execute this Lease on behalf of the parties they represent.

        47TH: Landlord shall indemnify, defend and hold harmless Tenant, its
parent, subsidiaries and affiliates, and their respective officers, directors,
shareholders and employees, from and against any and all damages, liabilities,
actions, causes of action, suits, claims, demands, losses, costs and expenses
(including without limitation reasonable attorneys' fees and disbursements and
court costs) to the extent arising from or in connection with (i) the negligence
or willful misconduct of Landlord, its agents, employees, representatives or
contractors or (ii)

                                       5
<PAGE>
Landlord's breach of any of the provisions of this Lease; provided, however,
that Landlord shall have no liability under this Section to the extent any such
damages, liabilities, actions, causes of action, suits, claims, demands, losses,
costs or expenses are caused by the negligence or willful misconduct of Tenant,
its agents, employees, representatives or contractors. The provisions of this
Section shall survive the expiration or earlier termination of the Term of this
Lease, as the same may be extended.

                                       LANDLORD:
