delivering a notice in writing (the "Notice of Termination") to the Employer,
and the Continuing Compensation and Benefits' provisions of this Agreement
shall apply.

c. Continuing Compensation and Benefits.

    i.  (a) if, at the time of termination of the Executive's employment
        in accordance with Section b hereof, a Tax Change has also
        occurred, the Employer shall make a lump-sum cash payment to the
        Executive no later than thirty (30) days following the date of
        such termination in an amount ("X") determined pursuant to the
        following formula: X=(2.99A-B) x (1+C).

        For the purpose of the foregoing formula,
        A = The Executive's base amount (determined pursuant to Internal
            Revenue Code Section 280G(b)(3)(A)) on the date of the
            Tax Change
        B = The present value of all other amounts which qualify as payments
            under Internal Revenue Code Section 280G(b)(2)(A)or(B) (without
            regard to the provisions of Code Section 280G(b)(2)(A)(ii)), such
            present value to be determined pursuant to the provisions of
            Internal Revenue Code Section 280G;
        C = 120% times 0.5 times the lowest of the semiannual applicable
            federal rates (determined pursuant to Internal Revenue Code
            Section 1274(d)) in effect on the date of the Tax Change; and
        D = The number of whole semiannual periods plus any fraction of a
            semiannual period from the later of the date of the Tax Change or
            the Change in Control or Ownership to the date of termination of
            the Executive's employment.

Notwithstanding the foregoing or any other provision of this Agreement
to the contrary, if the amount determined in "B" above equals or
exceeds 2.99 times the amount determined under "A" above, no payment
shall be made to the Executive under this Section.

(b) If, at the time of termination of the Executive's employment in
accordance with Section b hereof, a Tax Change has not occurred, the
Employer shall make a lump-sum cash payment to the Executive no later
than thirty (30) days following the date of such termination in an
amount equal to (A) 2.99 times the lesser of (i) the Executive's base
amount determined pursuant to the principles set forth in the
regulations promulgated under Code Section 280G(b)(3)(A) and as though
a Tax Change has occurred on the date of the Executive's termination of
employment and (ii) the Executive's base amount so determined but as
though a Tax Change will occur in the calendar year following the date
of the Executive's termination of employment, minus (B) any other
amounts paid or payable within thirty (30) days following the
Executive's termination of employment which would constitute (or be
presumed to constitute payments under Code Section 280G(b)(2)(A) or (B)
(without regard to the provisions of Code Section 280G(b)(2)(A)(ii)) if
a Tax Change had occurred on the date of such termination of
employment.

    ii.  The Executive shall not be required to mitigate the amount of any
         payment provided for in subsection c(i) by seeking other
         employment or otherwise, nor shall the amount of any payment or
         benefit provided for in subsection c(i) be reduced by any
         compensation earned by the Executive as the result of employment
         by another employer or by reason of the Executive's receipt of or
         right to receive any retirement or other benefits after the date
         of termination of employment or otherwise, except as otherwise
         provided therein.
    iii. Upon written request of the Executive, the Employer's obligation
         to make the payment under this Section shall be secured in total
         (i) by a standby letter of credit obtained by the Employer from a
         recognized financial institution the long-term obligations of
         which are rated, on the date of the request, investment grade or
         better by Standard & Poor's Corporation or Moody's Investors
         Service, Inc. or(ii) by other security as the Executive shall
         approve, obtained within ten (10) days of the Executive's written
         request following a Change in Control or Ownership.

    iv.  The Employer shall pay all reasonable legal fees and related
         expenses (including the costs of experts, evidence and counsel
         and expenses included in connection with an arbitration or in
         other litigation or appeal) incurred by the Executive as a result
         of (i)(a) his delivery of a Notice of Termination or (i)(b) his
         seeking to obtain or enforce any right or benefit provided by
         this Agreement.

d.  Termination for Cause. The Employer may terminate the Executive's
    Employment for "Cause." For purposes of this Agreement, "Cause" means
    the occurrence of either of the following:

    i.  The Executive's conviction of, or plea of guilty or nolo contendere
        to, a felony or a crime of falsehood or involving moral
        turpitude; or

    ii. The willful failure by the Executive to substantially perform his
        duties to the Employer, other than a failure resulting from the
        Executive's incapacity as a result of the Executive's Disability,
        which willful failure results in demonstrable material injury
        and damage to the Employer. Notwithstanding the foregoing, the
        Executive's Employment shall not be deemed to have been
        terminated for Cause if such termination took place as a result
        of:
        a. Questionable judgment on the part of the Executive;
        b. Any act or omission believed by the Executive in good faith,
           to have been in or not opposed to the best interests of the
           Employer; or
        c. Any act or omission in respect of which a determination could
           properly be made that the Executive met the applicable standard
           of conduct prescribed for indemnification or reimbursement or
           payment of expenses under the Employer's By-laws or the laws of
           New Jersey, or the directors and officers' liability insurance
           of the Employer or any Employer, in each case as in effect at
           the time of such act or omission.

If the Executive's Employment is terminated for Cause, all rights of the
Executive under this Agreement shall cease as of the effective date of such
termination, except that the Executive (i) shall be entitled to receive
accrued Salary through the date of such termination and (ii) shall be
entitled to receive the payments and benefits to which he is then entitled
under the employee benefit plans of the Employer or any affiliate thereof as
of the date of this termination.

Adopted by the Board of Directors on January 25, 1996.

rules and regulations contained in Tenant's Lease regarding their
conduct on the Premises.  Proof of such agreements shall be given to

23. INDEMNIFICATION.  Tenant shall not do, nor permit to be done, any
act or thing in or upon the Premises, which may, will, or does subject
Landlord to any claims, penalties, expenses, judgments,
responsibility, liability, damages or similar occurrence by reason of
damage or loss to any property or harm and/or injury (including death)
to any persons at any time.

and/or occupancy of the Premises and/or the conduct of Tenant's
business and/or the breach by Tenant of any of the terms and
conditions of this Lease and/or similar reason.

24. FAILURE TO GIVE POSSESSION.  If Landlord, for any reason, shall be
unable to give possession of the Premises on the date set for the
commencement of the Term, Landlord shall not be subject to any
liability for such failure. Under such circumstances, provided the
delay is not caused or contributed to by Tenant, the rent payments
shall not commence until possession of the Premises is given or the
Premises are available for occupancy by Tenant, whichever occurs
first. Failure to give possession on the date of commencement of the
term shall in no way affect the validity of this Lease or the
obligations of Tenant hereunder nor shall it be construed in any way
as an extension to the Term or expiration date of this Lease.
    If Landlord, at its option, grants Tenant permission to enter
into the possession of the Premises prior to the date specified as the
commencement of the Term, Tenant agrees that such occupancy shall be
pursuant to the terms and conditions of this Lease.

25. MECHANICS LIEN.  Tenant shall not permit nor allow any notice of

a mechanic's lien is filed for work claimed to have been done or for
materials claimed to have been furnished to Tenant, same shall be
discharged of record and satisfied by Tenant within five (5) days
thereafter at Tenant's own cost and expense, or Tenant shall file a
bond pursuant to statute releasing such liens. Failure to do so shall
entitle Landlord to resort to such remedies as are provided herein in
case of any default of this Lease, in addition to such as are
permitted by law.

liability to Landlord, its employees, agents, invitees and similar
parties; (b) hindrance or molestation from Tenant, its employees, and
agents; and (c) such entry constituting an eviction of Tenant or

27. ASSIGNMENT.
    a. Tenant shall not assign, mortgage, pledge, encumber or in any
manner transfer this Lease or any portion thereof, or any interest
herein, or sublet the whole or any part of the Premises, without
obtaining the approval of Landlord. In the event of any such
occurrence, with or without Landlord's approval, Tenant shall,
nevertheless, remain liable for the performance of all of the terms
and conditions of this Lease and will require any assignee/ sub lessee
to execute and deliver to Landlord an assumption of all of the terms
and conditions of this Lease in form satisfactory to Landlord.
Landlord shall be entitled to, and Tenant shall promptly remit to
Landlord, any profit which may inure to the benefit of Tenant as a
result of any partial or entire subletting of the Premises or
assignment of this Lease, whether or not approved by Landlord.
    b. For the purposes of this paragraph, Tenant understands that
the transfer of a majority of Tenant's stock is tantamount to an
assignment.
    c. As a condition precedent to Tenant's right to sublease the
Premises or to assign this Lease, Tenant shall, at Tenant's own
expense, first comply with ECRA and fulfill all of Tenant's
environmental obligations under this Lease pursuant to paragraph 52.
which also arise upon termination of Tenant's lease term.  If this
condition is not satisfied, then Landlord shall have the right to
withhold consent to sublease or assignment.
    Tenant shall promptly furnish to Landlord true and complete
copies of all documents, submissions and correspondence provided by
Tenant to the Element and all documents, reports, directives and
correspondence provided by the Element to Tenant.  Tenant shall also

the Premises.  Tenant shall notify Landlord in advance of all meetings
scheduled between Tenant and NJDEP, and Landlord may attend all such
meetings.
    d. Should Tenant make an assignment or sublet the Premises or
any portion thereof without the approval of Landlord, then Landlord
may, at its option, terminate this Lease by giving Tenant five (5)
days notice of Landlord's intention to do so and, upon the expiration
of five (5) days, this Lease shall terminate and Tenant shall
peaceably quit and surrender the Premises to Landlord; nevertheless

Lease shall not, nor shall any interest therein, be assignable as to
the interest of Tenant by operation of law, without the approval of
Landlord.
    e. Subletting or assigning this Lease to anyone other than an
actual user of the Premises is positively prohibited.
    f. Tenant may assign this Lease or sublet the Premises or any

or any portion thereof, to a wholly owned subsidiary.

28. SUBORDINATION.  This Lease shall be subject and subordinate at all
times to the lien of any mortgages and/or other encumbrances, common
right-of-way's, easements and similar items existing or hereafter
placed upon the Premises by Landlord, or with the permission of
Landlord, without the necessity of any further instrument or act on

-10-
<PAGE>

the part of Tenant to effectuate such subordination.  Tenant agrees,
however, at the election of a mortgagee, to attorn to any holder of
any mortgage to which this Lease is subordinate.  Tenant agrees to
execute and deliver promptly upon demand, and without charge, such
further instrument or instruments evidencing such subordination of
this Lease to the lien of any mortgage and/or other encumbrance.
Tenant hereby irrevocably appoints Landlord as Tenant's attorney-in-
fact to execute and deliver such instrument or instruments for and in
the name of the Tenant provided same have not been executed by Tenant
within ten (10) days after Landlord's notice to Tenant.
    Landlord agrees that the subordination of the Lease to any
future mortgage relating to the Premises shall be conditional and
contingent upon any such mortgagee's agreeing that, so long as Tenant
is not in default under the terms and conditions of the Lease, such
mortgages shall not disturb Tenant's use, possession and occupancy of
the Premises.

29. CERTIFICATIONS.  Tenant agrees, within ten (10) days after
Landlord's notice, to execute, acknowledge and deliver to Landlord a
written instrument in recordable form certifying:  (1) that this Lease
is unmodified and in full force and effect (or if there have been
modifications, that the same are in full force and effect as modified
and stating the modifications); (2) that the Tenant has accepted
possession of the Premises and the date on which the term of the Lease
commenced; (3) the dates to which rent and additional rent have been
paid in advance, if any; (4) whether or not to the best knowledge of
the signer of such certificate, Landlord is in default in the
performance of any covenant of this Lease, and, if so, specifying each
such default of which the signers may have knowledge; (5) any other
reasonable stipulation as may be required and/or requested by
Landlord.  It is understood that such instrument may be relied upon by
a prospective purchaser of the fee or any mortgagee of the Premises.
    Tenant shall provide to Landlord, if requested, its latest
audited financial statement, accurately reflecting its financial
condition for the latest fiscal year of Tenant.  It is understood that
such statement may be relied upon by a prospective purchaser of the
fee or any mortgagee of the Premises.

30. DEFAULT.  The occurrence of any of the following shall constitute
    a material default and breach of this Lease by Tenant:
a. Failure of Tenant to accept possession of the Premises within
thirty (30) days after the effective date of the Lease;
    b. The vacating or abandonment of the Premises by Tenant;
    c. The failure by Tenant to pay, when due, any installment of
rent hereunder or any additional rent or any such other sum herein
required to be paid by Tenant;
    d. A failure by Tenant to observe and perform any other
provision or terms and conditions of this Lease to be observed or
performed by Tenant, where such failure continues for fifteen (15)
days (or a lesser time period when an emergency or law requires or
makes such a reduction for abatement and/or correction prudent; or
when a lesser or non-notice provision is specifically provided for in
any covenant of this Lease) after written notice thereof from Landlord
to Tenant provided, however, that if the nature of the default is such
that the same cannot reasonably be cured within such fifteen (15) day
period, Tenant shall not be deemed to be in default if Tenant shall
within such period commence such cure and thereafter diligently
prosecute the same to completion;
    e. The filing of a petition by or against Tenant for
adjudication as a bankrupt or insolvent or for its reorganization or
for the appointment pursuant to any local, state or Federal bankruptcy
or insolvency law of a receiver or trustee of Tenant's property; or an
assignment by Tenant for the benefit of creditors; or the taking of
possession of the property of Tenant by any local, state or Federal
governmental officer or agency or court appointed official for the
dissolution or liquidation of Tenant or for the operating, either
temporary or permanent, of Tenant's business; provided, however, that
if any such action is commenced against Tenant, the same shall not
constitute a default if Tenant causes the same to be dismissed within
thirty (30) days after the filing of same.

                                  REMEDIES
                                  --------
Upon the occurrence of any such event of default set forth
above:
    a. Landlord may (but shall not be required to) perform for the
account of Tenant the curing of any default of Tenant and immediately
recover as additional rent any expenditure made and the amount of any
obligations incurred in connection therewith, plus interest at the
rate of four percent (4%) per annum over the Midlantic National
Bank/South prime rate from the date of such expenditure;
    b. Tenant may cure any monetary default by making payment of the
monies due, together with a late charge of 5% of the amount due not
later than ten (10) calendar days after notice of the default has been
given to Tenant.  If said default should continue for a longer period,
Landlord may accelerate all rent and additional rent due for the
succeeding nine (9) months of the term of this Lease and declare the
same to be immediately due and payable.
    c. Tenant may cure any non-monetary default by correcting the
default condition described in Landlord's notice to Tenant if said
corrections are completed within twenty (20) calendar days after
notice of the default has been given to Tenant.  If said default
should continue for a longer period, Landlord may accelerate all rent
and additional rent due for the succeeding nine (9) months of the term
of this Lease and declare the same to be immediately due and payable.
    d. In the event of default, and the failure of Tenant to cure
same within the designated time period, Landlord, at its option, may
serve notice upon Tenant that this Lease and the then unexpired term
hereof and all renewal options shall cease and expire and become
absolutely void on the date specified in such notice, to be not less
than five (5) days after the date of such notice without any right on
the part of the Tenant to save the forfeiture by payment of any sum
due or by the performance of any terms, provision, covenant, agreement
or condition broken; and, thereupon and at the expiration of the time
limit in such notice, this Lease and the term hereof granted, as well
as the right, title and interest of the Tenant hereunder, shall wholly
cease and expire and become void in the same manner and with the same
force and effect (except as to Tenant's liability) as if the date
fixed in such notice were the date herein granted for expiration of
the term of this Lease.  Thereupon, Tenant shall immediately quit and
surrender to Landlord the Premises, and Landlord may enter into and
repossess the Premises by summary proceedings, detainer, ejectment or
otherwise and remove all occupants thereof and, at Landlord's option,
any property thereon without being liable to indictment, prosecution
or damages therefore.  No such expiration or termination of this Lease
shall relieve Tenant of its liability and obligations under this
Lease, whether or not the Premises shall be relet;
    e. Landlord may, at any time after the occurrence of any event
of default, re-enter and repossess the Premises and any part thereof
and attempt in its own name, as agent for Tenant if this Lease not be
terminated or in its own behalf if this Lease be terminated, to relet
all or any part of such Premises for and upon such terms and to such
persons, firms or corporations and for such period or periods as
Landlord, in its sole discretion, shall determine, including the term
beyond the termination of this Lease; and Landlord shall not be
required to accept any tenant offered by Tenant or observe any
instruction given by Tenant about such reletting or do any act or
exercise any care or diligence with respect to such reletting or to
the mitigation of damages. For the purpose of such reletting, Landlord
may decorate or make repairs, changes, alterations or additions in or
to the Premises to the extent deemed by Landlord desirable or
convenient; and the cost of such decoration, repairs, changes,
alterations or additions shall be charged to and be payable by Tenant
as additional rent hereunder, as well as any reasonable brokerage and
legal fees expended by Landlord; and any sums collected by Landlord
from any new tenant obtained on account of the Tenant shall be
credited against the balance of the rent due hereunder as aforesaid.
Tenant shall pay to Landlord monthly, on the days when the rent would
have been payable under this Lease, the amount due hereunder less the
amount obtained by Landlord from such new Tenant;

-12-
<PAGE>

    f. The parties recognize and agree that the damage to Landlord
resulting from any failure by Tenant to timely surrender possession of
the Premises will be substantial, will exceed the amount of the
monthly installments of the Rent payable hereunder, and will be
impossible to measure accurately.  Tenant therefore agrees that if
possession of the Premises is not surrendered to Landlord upon the
expiration date or sooner termination of the Lease, in addition to any
other rights or remedies Landlord may have hereunder or at law, Tenant
shall pay to Landlord, as liquidated damages, for each month and for
each portion of any month during which Tenant holds over in the
Premises after the expiration date or sooner termination of this
Lease, a sum equal to two times the aggregate of that portion of Base
Annual Rent and Additional Rent that was payable under this Lease
during the last month of the Term.
Nothing herein contained shall be deemed to permit Tenant to
retain possession of the Premises after the expiration date or sooner
termination of the Lease.
    g. In addition to all remedies provided herein or by law, Tenant
shall pay to Landlord reasonable attorneys fees and court costs and
any other expenses incurred as a result of such breach or default.

termination specified by Landlord pursuant to notice as provided for
elsewhere in this Lease:  (a) Tenant shall remove all of its personal
property from the Premises; (b) Tenant shall peacefully quit and
surrender to Landlord the Premises, broom clean and in the same
condition in which Tenant has agreed to keep it during the Term.
Tenant's obligation to observe or perform this covenant shall survive
the expiration or prior termination date of this Lease; (c) Tenant,
for itself and on behalf of any and all persons claiming through or
under it, including, but not limited to, creditors of every kind,
shall and does hereby waive and surrender all rights and privileges
which it may have under or by reason of any present or future law, to

same in any manner as Landlord, at its option, elects, all at the risk
and cost of Tenant and without any liability to Landlord whatsoever.
    If during the last month of the term or prior termination,
Tenant has removed all or substantially all of the Tenant's property
from the Premises, Landlord may, without notice to Tenant, immediately
enter the Premises to renovate and decorate the Premises, without
liability to Tenant and without reducing or otherwise affecting
Tenant's obligations hereunder.

32. NON-WAIVER BY LANDLORD.  Landlord may restrain any breach or
threatened breach of any covenant of this Lease by Tenant.  However,
the recitation herein of any particular remedy shall not preclude the
Landlord from any other remedy it may have, either at law or in
equity. Landlord, at its option, may pursue more than one remedy
available either concurrently or separately.  The failure of Landlord
to insist upon the strict performance of any one of the terms and
conditions of this Lease or to exercise any right, remedy or election
provided for in this Lease, or permitted by law, shall not constitute
or be construed as a waiver or relinquishment of such right, remedy or
election.  Landlord may, at its option, mitigate any damages caused or
arising out Tenant's breach of any of the terms and conditions of this
Lease, but shall not be under any obligation or duty to do so.  Any
rights and remedies of Landlord, whether created by the terms of this
Lease or existing at law, in equity, or otherwise, shall be distinct,
separate and cumulative and no one of them, whether exercised by
Landlord or not, shall be deemed to be in exclusion of any other.

shall and may peaceably and quietly have, hold and enjoy the Premises

34. SECURITY.  Upon execution of this Lease, Tenant shall deposit with
Landlord the sum of $10,270.00 (carried over) as security for the
faithful performance and observance by Tenant of the terms and
conditions of this Lease.  The depositing of said sum with the
Landlord is a condition precedent to the valid execution of the Lease.
Landlord, at its option, may use, apply or retain the whole or any
part of the security so deposited for the payment of any sum for which
Tenant is in default or for any sum which Landlord, at its option, may
expend by reason of Tenant's default of any of the terms and
conditions of this Lease.  Any expenditures made by Landlord as herein
stipulated shall be paid by Tenant as additional rent.  Landlord shall
be permitted to co-mingle Tenant security funds with other funds of
Landlord and shall not be required to pay interest on any sum so held.
In the event that Tenant shall fully and faithfully comply with
all the terms and conditions of this Lease, the security shall be
returned to Tenant after the date fixed as the end of the Lease and
after delivery of the Premises by Tenant to Landlord pursuant to the
terms and conditions of this Lease.
    In the event of a sale of the Premises, Landlord shall have the
right to transfer the security to the buyer and Landlord shall
thereupon be relieved by Tenant from all liability for the return of
such security and Tenant agrees to look to the buyer solely for the
return of said security.  The provisions hereof shall apply to every
transfer or assignment made of the security to a new buyer.  Tenant
further covenants that it will not assign or encumber or attempt to
assign or encumber the monies deposited herein as security and that
neither the Landlord nor its successors or assigns shall be bound by
any such assignment, encumbrance, attempted assignment or attempted
encumbrance.

respective parties shall and hereby do waive trial by jury in any
action or proceeding brought by either of the parties hereto against
the other upon a claim for rents.
    In all actions involving any claim of violation of any non-
economic clause, term or provision of this Lease and specifically any
action involving any claim of negligence by either party, either shall
have and reserve all rights provided by law to trial by jury.
    This Lease shall be construed without regard to any presumption
or other rule requiring construction against the party causing this
Lease to be drafted.

37. SIGNS.  The Tenant shall not place nor allow to be placed any
signs upon or about the exterior of the building or the grounds of the

employees, and similar parties as to the condition or usefulness of
the Premises; (b) Tenant does not acquire any rights, easements or
licenses by implication or otherwise, except as are specifically

implied warranties; (d) upon execution of this Lease or anytime
thereafter Tenant assumes the full and sole responsibility for the
condition, safety, operation and management of the Premises pursuant
to the terms and conditions contained herein.

40. LANDLORD'S APPROVAL.  Except where specifically stated otherwise:
    Whenever Landlord's approval or consent is required pursuant to
any term or condition of this Lease, such approval shall be in writing
and in advance for each occurrence. Landlord is under no duty or
obligation to grant approvals.
    Whenever this Lease provides for a Landlord's option, it is
agreed such does not imply or constitute a duty or an obligation of
Landlord.
    Whenever this Lease provides for Landlord's approval which shall
not be unreasonably withheld, it is agreed that Tenant's remedy in the
event of Landlord's non-approval is limited to specific performance.

41. NET LEASE.  It is intended that the rent and additional rent
reserved hereunder shall be an absolutely net return to the Landlord
throughout the Term.  The rent and additional rent reserved hereunder

dedication of the Premises or any portion thereof.

45. COMPLIANCE WITH THE NJ ENVIRONMENTAL CLEANUP RESPONSIBILITY ACT.
    a. Tenant shall, at Tenant's own expense, comply with the
Environmental Cleanup Responsibility Act, N.J.S.A. 13:lK-6 et seq.,
the regulations promulgated thereunder and any successor legislation
and regulations, and any amendments or additions thereto, (hereinafter
referred to as 'ECRA').  Tenant shall, at Tenant's own expense, make
all submissions to, provide all information to, and comply with all
requirements of, the Industrial Site Evaluation or its successor
('Element') of the New Jersey Department of Environmental Protection
('NJDEP').
    b. Tenant's obligations under this paragraph shall arise if
there is any closing, terminating or transferring of operations of an
industrial establishment at the premises pursuant to ECRA, whether
triggered by Landlord or Tenant.
    c. Provided this Lease is not previously cancelled or terminated
by either party or by operation of law, Tenant shall commence its
submission to the Element in anticipation of the end of the lease term
no later than one (1) year prior to the expiration of the lease term.
Tenant shall promptly furnish to Landlord true and complete copies of
all documents, submissions, correspondence and oral or written
communications provided by Tenant to the Element, and all documents,
reports, directives, correspondence and oral or written communications
by the Element to Tenant.  Tenant shall also promptly furnish to

reports obtained and prepared from samples and tests taken at and
around the Premises.  Tenant shall notify Landlord in advance of all
meetings scheduled between Tenant and NJDEP, and Landlord may attend
all such meetings.
    d. Should the Element or any other division of NJDEP determine
that a cleanup plan be prepared and that a cleanup be undertaken
because of a spill or discharge of a hazardous substance or waste at
the Premises which occurred during the term of the Lease, Tenant
shall, at Tenant's own expense, promptly prepare and submit the
required plan and financial assurances and shall promptly carry out
the approved plans.

negative declaration application, limited conveyance application or
other submission and shall promptly sign such affidavits and

    f. Should Tenant's operations at the Premises be outside of those
industrial operations covered by ECRA, Tenant shall, at Tenant's own
expense, obtain a letter of non-applicability or de minimus quantity
exemption from the Element prior to termination of the Lease term and
shall promptly provide Tenant's submission and the Element's exemption
letter to Landlord.  Should Tenant obtain a letter of non-
applicability or de minimus quantity exemption from the Element, then
Tenant shall, at Landlord's option, hire a consultant satisfactory to
Landlord to undertake sampling at the Premises sufficient to determine
whether or not Tenant's operations have resulted in a spill or
discharge of a hazardous substance or waste at or around the Premises.
Should the sampling reveal any spill or discharge of a hazardous
substance or waste, then Tenant shall, at Tenant's expense, promptly
clean up the Premises to the satisfaction of Landlord and NJDEP.
    g. If Tenant fails to obtain either:  (i) a non-applicability
letter; (ii) a de minimus exemption; (iii) a negative declaration; or
(iv) final approval of cleanup; (collectively referred to as "ECRA

termination of the lease term, then upon the expiration or earlier

-16-
<PAGE>

termination of the lease term Landlord shall have the option either to
consider the Lease as having ended or to treat Tenant as a holdover
tenant in possession of the Premises.  If Landlord considers the Lease
as having ended, then Tenant shall nevertheless be obligated to
promptly obtain ECRA clearance and to fulfill the obligations set
forth in subparagraph (f) above.  If Landlord treats Tenant as a
holdover tenant in possession of the Premises, then Tenant shall
monthly pay to Landlord double the regular and additional monthly rent
which Tenant would otherwise have paid, until such time as Tenant
obtains ECRA clearance and fulfills its obligations under subparagraph
(f) above, and during the holdover period all of the terms of this
Lease shall remain in full force and effect.
    h. Tenant represents and warrants to Landlord that Tenant intends
to use the Premises for printed circuit board assembly and related

Federal Executive Office of the President, Office of Management and
Budget: 36-61.  Tenant's use of the Premises shall be restricted to
the classifications set forth above unless Tenant obtains Landlord's
written prior written consent to any change in use of the Premises.
Prior to the commencement date of Tenant's lease term, Tenant shall
supply to Landlord an affidavit of an officer of Tenant ("Officer's
Affidavit") setting forth Tenant's SIC numbers and a detailed
description of the operations and processes Tenant will undertake at
the Premises, organized in the form of a narrative report including a
description and quantification of hazardous substances and wastes to
be generated, manufactured, refined, transported, treated, stored,
handled or disposed of at the Premises.  Following commencement of the
lease term, Tenant shall notify Landlord by way of a supplemental
Officer's Affidavit, as to any changes in Tenant's operation, SIC
number or use or generation of hazardous substances and wastes.
Tenant shall also supplement and update Officer's Affidavit upon each
anniversary of the commencement of the lease term.  Tenant shall not
commence or alter any operations at the Premises prior to (i)
obtaining all required operating and discharge permits or approvals,
including, but not limited to, air pollution control permits and
pollution discharge elimination system permits from NJDEP, all
governmental or public authorities having jurisdiction over Tenant's
operations or the Premises, and (ii) providing copies of permits and
approvals to Landlord.
    i. Tenant shall permit Landlord and Landlord's agents, servants
and employees, including, but not limited to, legal counsel and
environmental consultants and engineers, access to the Premises for
the purposes of environmental inspections and sampling during regular
business hours, or during other hours either by agreement of the
parties or in the event of any environmental emergency.  Tenant shall
not restrict access to any part of the Premises, and Tenant shall not
impose any conditions to access.   In the event that Landlord's
environmental inspection shall include sampling and testing of the
Premises, Landlord shall use its best efforts to avoid interfering
with Tenant's use of the Premises, and upon completion of sampling and
testing shall repair and restore the affected areas of the Premises
from any damage caused by the sampling and testing.
    j. Tenant's indemnification of Landlord as set forth elsewhere
within this Lease shall extend to any and all claims, liabilities,
losses, damages and costs, foreseen or unforeseen, including without
limitation to reasonable counsel, engineering and other professional
or expert fees, which Landlord may incur by reason of Tenant's action
or non-action with regard to Tenant's obligations under this
paragraph.

this paragraph shall be restrainable by injunction without limiting
Landlord's right to remedy as provided for elsewhere in this Lease.

or permit upon the Premises or generate, create, emit, or dispose at

all applicable state, federal, municipal and county permits relating
to Tenant's processes or operations or the generation, storage or
disposal of hazardous substances, materials or wastes on the Premises.

Tenant acknowledges that during the term of this Lease, chemical(s) or
material(s) which Tenant uses, generates, repackages, stores or
permits on the Premises may be legally banned or subject to mandatory
modification or conversion.  Tenant agrees that it will not, on the
basis of such legal ban or mandatory modification or conversion, claim

abatement of rent. Tenant further agrees that it will comply fully,
and at Tenant's own expense, with any said legal ban or mandatory
modification or conversion.
