(1)  ORGANIZATION AND BASIS OF PRESENTATION

      The  unaudited  consolidated  condensed  financial  statements  have been
prepared  from  the  books  and  records  of  Enzon,  Inc.  and subsidiaries in
accordance with generally accepted accounting principles for  interim financial
information.   Accordingly,  they  do  not  include all of the information  and
footnotes  required by generally accepted accounting  principles  for  complete
financial  statements.    In   the   opinion  of  management,  all  adjustments
(consisting only of normal and recurring  adjustments) considered necessary for
a fair presentation have been included.  Interim  results  are  not necessarily
indicative of the results that may be expected for the year.

(2)  NET LOSS PER COMMON SHARE

      Net  loss per common share is based on net loss for the relevant  period,
adjusted for  cumulative  undeclared  preferred stock dividends of $163,500 and
$175,051, respectively, for the nine months  ended March 31, 1995 and 1994, and
$54,500 and $58,051, respectively, for the three  months  ended  March 31, 1995
and  1994,  divided  by  the  weighted  average  number  of  shares issued  and
outstanding  during  the  period.   Stock  options,  warrants and common  stock
issuable  upon  conversion of the preferred stock are not  reflected  as  their
effect would be antidilutive  for  both  primary and fully diluted earnings per
share computations.  The total number of shares  issued  to former shareholders
of Enzon Labs Inc. (formerly known as Genex Corporation), which was acquired on
October  31,  1991,  have  been  included  in  the weighted average  number  of
outstanding shares, as if all shares had been issued  on  October 31, 1991, the
date of acquisition.

(3)  INVENTORIES

      The composition of inventories at March 31, 1995 and  June 30, 1994 is as
follows:

</TABLE>
(4)  CASH FLOW INFORMATION

      The  Company  considers  all  highly  liquid  securities  with   original
maturities  of three months or less to be cash equivalents.  Cash payments  for
interest were  approximately  $1,900 and $3,700 for the nine months ended March
31, 1995 and 1994, respectively.   There  were  no income tax payments made for
the nine months ended March 31, 1995 and 1994.  During  the  nine  months ended
March 31, 1995, the Company issued 100,000 shares of unregistered Common  Stock
in  order  to acquire an option to purchase the remaining facility it currently
leases in Piscataway, New Jersey.  During the nine months ended March 31, 1994,
8,000 shares  of Series A Cumulative Convertible Preferred Stock were converted
to 21,978 shares of Common Stock.  Accrued dividends of $64,000 on the Series A
Cumulative Convertible  Preferred  Stock  that  was  converted, were settled by
issuing  7,032  shares  of  Common  Stock and cash payments  totalling  $9  for
fractional shares for the nine months  ended  March  31,  1994.   There  was no
conversion  of  the  Series A Cumulative Convertible Preferred Stock during the
nine months ended March 31, 1995.

(5)  STOCKHOLDERS' EQUITY

      During the nine  months  ended  March 31, 1995, the Company concluded its
agreement with Susquehanna Brokerage Services,  Inc. ("Susquehanna") dated June
24,  1994.   Under  this agreement, the Company sold,  in  a  public  offering,
954,000 shares of newly  issued  Common  Stock.   The  shares  were  sold  at a
weighted  average  price  of  $2.06 per share, resulting in net proceeds to the
Company of approximately $1,747,000.

(6)  NON-QUALIFIED STOCK OPTION PLAN

      During the nine months ended March 31, 1995, the Company issued 1,326,078
stock options at an average exercise  price  of  $2.41 under the Company's Non-
Qualified  Stock Option Plan, (the "Plan") of which  367,000  were  granted  to
officers and  213,328  to independent directors.  All options granted under the
plan during the nine months  ended  March 31, 1995, were granted at prices that
equalled or exceeded the fair market  value of the stock at the time the option
was granted.  The options also have a minimum vesting period of six months.

(7)  COMMITMENTS

      During December 1994, the Company  amended its long-term supply agreement
for unmodified L-asparaginase, one of the  raw  materials used in the Company's
product  ONCASPAR<reg-trade-mark>.  The  amendment  eliminated   the  Company's
obligation  to  purchase $870,000 of raw material for the year ending  December
31, 1994 and increased the purchase commitment for the year ending December 31,
1995 by $870,000  to  $1,700,000.  Under the amended agreement, the Company has
the option to fully satisfy  $870,000  of the purchase requirement for the year
ending December 31, 1995, without taking  delivery  of the product, by making a
payment of $350,000.

(8)  RESTRUCTURING EXPENSES

      During  the  quarter  ended  March  31,  1995,  the Company  reduced  its
workforce by approximately 30 employees, bringing the total number of employees
to 134 as of March 31, 1995.  As a result of these reductions,  the Company was
able  to  move  its  General  and  Administrative  operations into its existing
facility at 20 Kingsbridge Road in Piscataway, New Jersey.

      On March 31, 1995, the Company terminated its  lease  for  83,000  square
feet  at 40 Kingsbridge Road in Piscataway, New Jersey, its former General  and
Administrative  facility.   As  part of the termination agreement, the landlord
was  able to draw down on a $600,000  letter  of  credit  that  served  as  the
security  deposit  for  both buildings that the Company occupied on Kingsbridge
Road  in Piscataway.  The  termination  payment,  severance  related  to  staff
reductions, as well as the write-off of leasehold improvements, moving expenses
and commission due the Company's real estate broker, related to the termination
of the  40 Kingsbridge lease were recorded as a restructuring charge during the
quarter ended  March 31, 1995.  The termination of the Company's 40 Kingsbridge
Road facility lease  reduces  the  Company's  future  minimum lease payments by
$132,000, $650,000, $729,000 and $729,000 for each of the  fiscal  years ending
June  30,  1995,  1996,  1997  and  1998,  respectively,  and  an  aggregate of
$7,161,000 for the years thereafter.

(9)  OPERATING LEASES

      During October 1994, the Company entered into a sale-leaseback  agreement
for   certain  research  and  development  equipment  valued  at  approximately
$830,000.   The equipment was sold at a price which exceeded book value and the
corresponding  lease is being accounted for as an operating lease.  The minimum
lease payments under the agreement are $448,000, $174,000, $174,000 and $43,000
for each of the  fiscal  years  ending  June  30,  1995,  1996,  1997 and 1998,
respectively.

(10)  SIGNIFICANT AGREEMENT - RHONE-POULENC RORER AGREEMENT

      During  January  1995,  the Company revised its exclusive U.S.  marketing
rights  license with Rhone-Poulenc  Rorer  Pharmaceuticals,  Inc.  ("RPR")  for
ONCASPAR.   Under  the  revised agreement, Enzon will earn a royalty of 10% for
the year ending December  31,  1995  and  23.5%  thereafter, until 2008, on net
sales of ONCASPAR up to agreed upon amounts, as opposed  to  50% of net profits
provided  for under the original agreement.  Additionally, Enzon  will  earn  a
royalty of  23.5%  for  the year ending December 31, 1995 and 43.5% thereafter,
until 2008 on net sales of  ONCASPAR  which  exceed the agreed upon limits with
the limitation that the total royalties earned  for  any  such  year  shall not
exceed  33%  of  net sales.  The revision eliminates RPR's requirement to  make
certain minimum advertising,  promotional  and  clinical  expenditures.  Future
decisions  regarding  clinical  development  will  be at RPR's discretion.  The
amended  agreement  also  provides  for  a  payment  of $3,500,000  in  advance
royalties, which was received in January 1995.  Royalties due under the revised
agreement will be offset against a credit of $5,970,000,  which  represents the
royalty advance plus reimbursement of certain RPR costs and interest  expenses,
before  cash  payments will be made under the agreement.  The revised agreement
also provides for  the  acceleration  of  the  remaining  $500,000  in  license
payments under the original license from June 30, 1995 to March 15, 1995.




<PAGE>
ITEM 2.     MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1995 VS. THREE MONTHS ENDED MARCH 31, 1994

REVENUES.  Revenues for the three months ended March 31,  1995 decreased by 38%
to  $4,814,000  as  compared to $7,708,000 for the same period  in  1994.   The
components of revenues are sales and contract revenues.  Sales increased by 67%
to $3,912,000 for the  three  months  ended  March  31,  1995  as  compared  to
$2,348,000  for  the  same  period  in  the  prior  year, due to an increase in
patients  receiving ADAGEN<reg-trade-mark>, increased  ONCASPAR<reg-trade-mark>
revenues from  Rhone-Poulenc  Rorer Pharmaceuticals, Inc. ("RPR") and increased
shipment of clinical supplies to  the Company's collaborative partner, Schering
Corporation  ("Schering").  Other than  approximately  $380,000  of  additional
clinical supplies,  which  are  scheduled for delivery during the next quarter,
the Company has no firm orders for  clinical  supplies  from  Schering.  ADAGEN
sales  for  the three months ended March 31, 1995 and 1994 were $2,148,000  and
$2,062,000, respectively.  Under the Company's amended exclusive U.S. marketing
license with  RPR,  depending on net sales levels, Enzon will earn a royalty of
between 10% and 23.5%  for  the year ending December 31, 1995 and between 23.5%
and 43.5% for the years thereafter  on  the  net  sales of ONCASPAR.  Royalties
earned under the amended agreement are limited in that  all royalties earned in
any  such  year shall not exceed 33% of net sales.  Contract  revenue  for  the
three months  ended March 31, 1995 decreased by 83% to $902,000, as compared to
$5,361,000 for  the same period in 1994.  The decrease was principally due to a
one time $5,000,000  payment from RPR received in the prior year related to the
Food and Drug Administration  ("FDA")  approval  of ONCASPAR.  During the three
months ended March 31, 1995 and 1994, the Company  had export sales of $572,000
and $577,000, respectively.  Sales in Europe were $519,000 and $547,000 for the
three months ended March 31, 1995 and 1994, respectively.

COST OF SALES.  Cost of sales, as a percentage of sales,  increased  to 21% for
the three months ended March 31, 1995 as compared to 16% for the same period in
1994.  The increase was due primarily to a charge recorded for the three months
ended March 31, 1995 for idle capacity at the Company's manufacturing facility,
and cost of sales related to clinical supplies of PEG-Intron A manufactured for
Schering  which  has  a  lower  margin than the other products sold during  the
quarter.  Prior to the approval of  ONCASPAR  in  February  1994, the Company's
first  FDA  approved  drug  for  a  potentially large patient population,  idle
capacity  was  charged to research and  development  expense.   In  the  fourth
quarter of fiscal  1994, the Company began classifying idle capacity as cost of
sales.   During  the  quarter  ended  March  31,  1995,  the  Company  utilized
approximately 76% of its  manufacturing  capacity  for  the  production  of its
approved products and clinical supplies for Schering.

RESEARCH  AND  DEVELOPMENT.   Research  and  development expenses for the three
months ended March 31, 1995 decreased by 50% to  $2,097,000 from $4,217,000 for
the  same period in 1994.  This decrease was primarily  due  to  (i)  decreased
research  facilities and occupancy costs due to a rent credit received from one
of the Company's  landlords  and  the  subleasing  of  certain facilities, (ii)
reductions   in   personnel,   principally   in   the  clinical  and   research
administration areas, and related costs, such as payroll  taxes  and  benefits,
(iii)  the  charging  of idle capacity to cost of sales during the three months
ended March 31, 1995, rather  than research and development expenses as was the
case  during  the  three months ended  March  31,  1994  and  (iv)  other  cost
containment measures taken by the Company.

SELLING,  GENERAL  AND   ADMINISTRATIVE   EXPENSES.    Selling,   general   and
administrative  expenses for the three months ended March 31, 1995 decreased by
38% to $1,537,000  from  $2,463,000  for the same period in 1994.  The decrease
was due to (i) reductions in personnel and related costs, such as payroll taxes
and benefits and (ii) other cost containment measures taken by the Company.

RESTRUCTURING EXPENSE.  During the quarter  ended  March  31, 1995, the Company
reduced its workforce by 30 employees bringing the total number of employees to
134 as of March 31, 1995.  As a results of these reductions,  the  Company  was
able  to terminate its lease for its General and Administrative headquarters at
40 Kingsbridge  Road,  Piscataway,  New  Jersey.   As  part  of the termination
agreement, the landlord was able to draw down on a letter of credit that served
as  a  security  deposit  on  both  of  the  buildings the Company occupied  on
Kingsbridge Road in Piscataway.  This termination payment and severance related
to  the  staff reduction as well as the write-off  of  leasehold  improvements,
moving expenses  and  commissions  due  the  Company's  real estate broker were
recorded as restructuring expenses during the quarter ended March 31, 1995.

OTHER INCOME/EXPENSE.  Other income/expense increased by  $157,000  to $174,000
for the three months ended March 31, 1995 as compared to $17,000 for  the  same
period  last year.  The increase was due principally to an increase in interest
bearing investments as well as an increase in interest rates and gains recorded
on the sale of equipment.

NINE MONTHS ENDED MARCH 31, 1995 VS. NINE MONTHS ENDED MARCH 31, 1994

REVENUES.  Revenues for the nine months ended March 31, 1995 decreased by 7% to
$10,874,000  as  compared  to  $11,752,000  for  the  same period in 1994.  The
components of revenues are sales and contract revenues.  Sales increased by 34%
to  $8,072,000  for  the  nine  months  ended  March 31, 1995  as  compared  to
$6,011,000  for  the  same period in the prior year,  due  to  an  increase  in
patients  receiving ADAGEN,  increased  ONCASPAR  revenues  from  RPR  and  the
shipment of  clinical  material to Schering.  Other than approximately $380,000
of additional clinical supplies,  which  are  scheduled for delivery during the
next  quarter,  the  Company  has  no firm orders for  clinical  supplies  from
Schering.  ADAGEN sales for the nine  months ended March 31, 1995 and 1994 were
$6,157,000 and $5,457,000, respectively.   Contract revenue for the nine months
ended March 31, 1995 decreased by 51% to $2,802,000,  as compared to $5,741,000
for the same period in 1994.  The decrease was principally  due  to a  one time
payment received during the nine months ended March 31, 1994 from  RPR  related
to  the FDA approval of ONCASPAR.  The decrease was offset in part by a payment
of $1,800,000  recorded  in  the nine months ended March 31, 1995 from Bristol-
Myers Squibb related to the exercise  of  its  option  under an agreement dated
September  1993,  to  acquire  a  worldwide  non-exclusive  license   for   all
therapeutic   indications   for   the  Company's  Single-Chain  Antigen-Binding
("SCA<trademark>") protein technology.   During the nine months ended March 31,
1995  and  1994, the Company had export sales  of  $1,571,000  and  $1,497,000,
respectively.   Sales  in  Europe  were  $1,390,000 and $1,384,000 for the nine
months ended March 31, 1995 and 1994, respectively.

COST OF SALES.  Cost of sales, as a percentage  of  sales, increased to 27% for
the nine months ended March 31, 1995 as compared to 16%  for the same period in
1994.   The increase was due primarily to (i) a charge recorded  for  the  nine
months ended  March  31,  1995 for idle capacity at the Company's manufacturing
facility and (ii) cost of sales  related  to  clinical supplies of PEG-Intron A
manufactured for Schering which has a lower margin than the other products sold
during the quarter.  Prior to the approval of ONCASPAR, the Company's first FDA
approved  drug for a potentially large patient population,  idle  capacity  was
charged to  research  and development expense.  In the fourth quarter of fiscal
1994, the Company began classifying idle capacity as cost of sales.

RESEARCH AND DEVELOPMENT.   Research  and  development  expenses  for  the nine
months ended March 31, 1995 decreased by 34% to $8,856,000 from $13,494,000 for
the same period in 1994.  This decrease was primarily due to (i) reductions  in
personnel,  principally  in the clinical and research administration areas, and
related costs, such as payroll  taxes  and  benefits, (ii) the charging of idle
capacity to cost of sales during the nine months  ended  March 31, 1995, rather
than research and development expenses as was the case during  the  nine months
ended  March 31, 1994, (iii) decreased research facilities and occupancy  costs
due to a  rent  credit  received  from  one  of the Company's landlords and the
subleasing of certain facilities and (iv) other cost containment measures taken
by the Company.

SELLING,   GENERAL   AND  ADMINISTRATIVE  EXPENSES.    Selling,   general   and
administrative expenses  for  the nine months ended March 31, 1995 decreased by
38% to $5,357,000 from $8,701,000  for  the  same period in 1994.  The decrease
was due to (i) reductions in personnel and related costs, such as payroll taxes
and benefits, (ii) decreased marketing and advertising  costs for ONCASPAR as a
result  of  the  Company's  license  agreement with RPR, and (iii)  other  cost
containment measures taken by the Company.   Under the Company's exclusive U.S.
marketing rights license, RPR is responsible for  all marketing and advertising
costs.




<PAGE>
RESTRUCTURING EXPENSE.  During the quarter ended March  31,  1995,  the Company
reduced its workforce by 30 employees bringing the total number of employees to
134  as  of March 31, 1995.  As a results of these reductions, the Company  was
able to terminate  its lease for its General and Administrative headquarters at
40 Kingsbridge Road,  Piscataway,  New  Jersey.   As  part  of  the termination
agreement, the landlord was able to draw down on a letter of credit that served
as  a  security  deposit  on  both  of  the  buildings the Company occupied  on
Kingsbridge Road in Piscataway.  This termination payment and severance related
to  the  staff reduction as well as the write-off  of  leasehold  improvements,
moving expenses  and  commissions  due  the  Company's  real estate broker were
recorded as restructuring expense during the quarter ended March 31, 1995.

OTHER INCOME/EXPENSE.  Other income/expense increased to  $945,000 for the nine
months ended March 31, 1995 as compared to $145,000 for the  same  period  last
year.   The  increase  was  principally due to an insurance settlement received
during  the nine months ended  March  31,  1995  related  to  ADAGEN  that  was
destroyed in shipment.

      The  Company  adopted the provisions of Statement of Financial Accounting
Standards No. 115, "Accounting  for  Certain  Investments  in  Debt  and Equity
Securities"  (SFAS  115) as of July 1, 1994.  The adoption of SFAS 115 did  not
have  a material impact  on  the  Company's  consolidated  condensed  financial
statements.

LIQUIDITY AND CAPITAL RESOURCES

      Enzon  had  $4,725,000 in cash and cash equivalents as of March 31, 1995.
The Company invests  its  excess  cash  in a portfolio of high-grade marketable
securities and United States government-backed securities.

      The  Company's  cash  reserves,  as  of  March  31,  1995,  decreased  by
$1,006,000 from June 30, 1994.  The decrease in cash reserves was caused by the
funding  of  operations  which was offset in part  by  the  proceeds  from  the
Company's  public  offering,   the   sale/leaseback  of  certain  research  and
development equipment and a royalty advance  of  $3,500,000 received related to
the renegotiation of the Company's exclusive U.S. marketing rights license with
RPR.

      During the nine months ended March 31, 1995,  the  Company  received  net
proceeds  of approximately $1,747,000 from the sale of 954,000 shares of Common
Stock  through   Susquehanna   Brokerage  Services,  Inc.  ("Susquehanna"),  as
underwriter.  During January 1995,  the  Company  revised  its  exclusive  U.S.
marketing  rights  license with RPR for ONCASPAR.  Under the revised agreement,
Enzon will earn a royalty  on  net  sales  of ONCASPAR as opposed to 50% of net
profits  provided  for  under the original agreement.   The  amended  agreement
provides for a payment of  $3,500,000  in advance royalties, which was received
in January 1995.  Royalties due under the  revised  agreement  will  be  offset
against  a  credit  of  $5,970,000,  which represents the royalty advances plus
reimbursement of certain RPR costs and  expenses,  before cash payments will be
made  under  the  agreement.   The  royalty advance is shown  as  a  long  term
liability on the consolidated balance  sheet  as  of March 31, 1995 and will be
reduced as royalties are recognized under the agreement.

      The Company's agreement with Sanofi Winthrop  Inc.  ("Sanofi"),  formerly
Sterling  Winthrop,  Inc., and the Eastman Kodak Company ("Kodak"), requires  a
credit to Sanofi for monies  not  expended for the development of PEG-SOD, PEG-
catalase  and  PEG-uricase  under  the  Company's  March  1987  stock  purchase
agreement with Kodak, pursuant to which  Kodak  advanced the Company $9,000,000
to fund all activities to obtain FDA approval for  these products and purchased
2,000,000  shares  of the Company's Common Stock for $6,000,000.   The  Company
believes that under the agreement, Sanofi may only apply the credit, shown as a
current liability in  the  consolidated  condensed  balance  sheet, against the
purchase of clinical supplies and the Company has no other obligation  to repay
the credit to Sanofi.  Sanofi has notified the Company that it does not require
future  clinical  supplies from the Company and, therefore, the Company has  no
further obligation under the agreement to supply PEG-SOD to Sanofi.

      As of March 31,  1995,  940,808 shares of Series A Cumulative Convertible
Preferred Stock ("Series A Preferred  Stock") had been converted into 3,093,411
shares of Common Stock. Accrued dividends  on  the converted Series A Preferred
Stock in the aggregate of $1,792,000 were settled  by  the  issuance of 232,383
shares  of  Common Stock.  The Company does not presently intend  to  pay  cash
dividends on  the  Series  A Preferred Stock.  As of March 31, 1995, there were
$1,094,500 of accrued and unpaid  dividends  on  the  Series A Preferred Stock.
Dividends accrue on the outstanding Series A Preferred  Stock  at  the  rate of
$218,000 per year.

      To  date,  the Company's sources of cash have been the proceeds from  the
sale of its stock through public and private placements, sales of ADAGEN, sales
of ONCASPAR, sales of its products for research purposes, contract research and
development fees,  technology  transfer  and license fees and royalty advances.
The Company's current sources of liquidity  are  its cash, cash equivalents and
interest  earned  on such cash reserves, sales of ADAGEN,  sales  of  ONCASPAR,
sales of its products  for  research  purposes  and  license  fees.  Management
believes that its current sources of liquidity will be sufficient  to  meet its
anticipated  cash requirements based, if necessary, on reduced spending levels,
through October 31, 1995.

      Upon exhaustion  of  the  Company's  current cash reserves, the Company's
continued operations will depend on its ability to realize significant revenues
from the commercial sale of its products, raise additional funds through equity
or  debt  financing, or obtain significant licensing,  technology  transfer  or
contract research  and  development fees.  There can be no assurance that these
sales, financings or revenue generating activities will be successful.

      In management's opinion,  the  effect  of inflation on the Company's past
operations has not been significant.

                          CHANGE OF CONTROL AGREEMENT


            AGREEMENT by and between Enzon, Inc.,  a  Delaware corporation (the
"Company"),  and                         (the "Executive"),  dated  as  of  the
day of                   , 1994.

            The Board of Directors of the  Company (the "Board") has determined
that it is in the best interests of the Company  and its stockholders to assure
that  the  Company  will  have  the  continued  dedication  of  the  Executive,
notwithstanding the possibility, threat or occurrence  of  a  Change of Control
(as defined in Section 2) of the Company.  The Board believes it  is imperative
to  diminish  the  inevitable  distraction  of  the Executive by virtue of  the
personal uncertainties and risks created by a pending  or  threatened Change of
Control and to encourage the Executive's full attention and  dedication  to the
Company  currently  and  in  the  event  of any threatened or pending Change of
Control,  and  to  provide  the  Executive  with   compensation   and  benefits
arrangements  upon  a Change of Control which ensure that the compensation  and
benefits expectations  of  the  Executive  will  be  satisfied  and  which  are
competitive   with  those  of  other  corporations.   Therefore,  in  order  to
accomplish these  objectives,  the  Board  has caused the Company to enter into
this Agreement.

            NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

1.          CERTAIN DEFINITIONS

            (a)   The "Effective Date" shall  mean  the  first  date during the
Change  of  Control  Period (as defined in Section 1(b)) on which a  Change  of
Control occurs.  Anything in this Agreement to the contrary notwithstanding, if
a Change of Control occurs  and  if the Executive's employment with the Company
is terminated prior to the date on  which  the Change of Control occurs, and if
it  is  reasonably  demonstrated  by the Executive  that  such  termination  of
employment  (i)  was at the request of  a  third  party  who  has  taken  steps
reasonably calculated  to  effect the Change of Control or (ii) otherwise arose
in connection with or anticipation  of  the  Change  of  Control,  then for all
purposes of this Agreement the "Effective Date" shall mean the date immediately
prior to the date of such termination of employment.

            (b)   The   "Change  of  Control  Period"  shall  mean  the  period
commencing on the date hereof  and  ending on the third anniversary of the date
hereof; provided, however, that commencing on the first anniversary of the date
hereof, and on each successive annual anniversary of the date hereof (such date
and each annual anniversary thereof shall  be  hereinafter  referred  to as the
"Renewal  Date"),  the Change of Control Period shall be automatically extended
so as to terminate three  years from such Renewal Date, unless at least 60 days
prior to the Renewal Date the  Company  shall give notice to the Executive that
the Change of Control Period shall not be so extended.

2.          CHANGE OF CONTROL

            For the purpose of this Agreement,  a  "Change  of  Control"  shall
mean:

            (a)   A "Board Change" which, for purposes of this Agreement, shall
have  occurred  if  a  majority  of  the seats (other than vacant seats) on the
Company's  Board  were  to be occupied by  individuals  who  were  neither  (i)
nominated by a majority of  the  Incumbent  Directors  nor  (ii)  appointed  by
directors  so  nominated.  An "Incumbent Director" is a member of the Board who
has been either  (i)  nominated  by  a majority of the directors of the Company
then in office or (ii) appointed by directors  so nominated, but excluding, for
this purpose, any such individual whose initial  assumption of office occurs as
a result of either an actual or threatened election  contest (as such terms are
used in Rule 14a-11 of Regulation 14A promulgated under the Securities Exchange
Act  of 1934, as amended (the "Exchange Act")) or other  actual  or  threatened
solicitation  of proxies or consents by or on behalf of a Person other than the
Board; or

            (b)   The  acquisition  by  any individual, entity or group (within
the meaning of Section 13(d)(3) or 14(d)(2)  of  the Exchange Act) (a "Person")
of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) of 50% or more of the then outstanding  voting  securities of the
Company (the "Outstanding Company Voting Securities"); provided,  however, that
the following acquisitions shall not constitute a Change of Control:   (x)  any
acquisition  by  the  Company, (y) any acquisition by any employee benefit plan
(or related trust) sponsored  or  maintained  by the Company or any corporation
controlled by the Company or (z) any acquisition by any corporation pursuant to
a reorganization, merger or consolidation, if,  following  such reorganization,
merger  or  consolidation, the conditions described in clauses  (i),  (ii)  and
(iii) of subsection (c) of this Section 2 are satisfied; or

            (c)   a  merger or consolidation of the Company with another entity
shall occur in which neither  the  Company nor a corporation that, prior to the
merger  or  consolidation,  was a subsidiary  of  the  Company,  shall  be  the
surviving entity; or

            (d)   a merger or  consolidation  of  the Company following which a
majority of the Outstanding Company Voting Securities  is  owned by a Person or
Persons  who  were not "beneficial owners" of such Outstanding  Company  Voting
Securities immediately prior to such merger or consolidation; or

            (e)   a voluntary or involuntary liquidation of the Company; or

            (f)   a  sale  or disposition by the Company of at least 80% of its
assets in a single transaction  or  a series of transactions (other than a sale
or disposition of assets to a subsidiary  of  the  Company in a transaction not
involving a Change of Control or a change in control of such subsidiary).

3.          EMPLOYMENT PERIOD

            The Company hereby agrees to continue the  Executive in its employ,
and  the Executive hereby agrees to remain in the employ  of  the  Company,  in
accordance  with  the  terms  and  provisions of this Agreement, for the period
commencing on the Effective Date and  ending  on  the third anniversary of such
date (the "Employment Period"), in the capacity of                      of  the
Company        responsible        for,        among        other        things,
  and,  subject to the general supervision of the Board, such other duties  and
responsibilities  as  are  not  inconsistent  with  the  express  terms of this
Agreement.   The Company agrees that it will not take any action, or  make  any
demands on the  Executive,  which may be deemed to arbitrarily, unreasonably or
unnecessarily interfere with  the performance of the services to be rendered by
the Executive hereunder.

4.          TERMS OF EMPLOYMENT

            (a)   POSITION AND DUTIES.

                  (i)   During  the  Employment  Period,  (A)  the  Executive's
position  (including  status,  offices,  titles  and  reporting  requirements),
authority,  duties and responsibilities shall be in accordance with  Section  3
hereof and (B)  the  Executive's  services  shall  be performed at the location
where the Executive was employed immediately preceding  the  Effective  Date or
any  office  which  is the headquarters of the Company and is less than 5 miles
from such location.

                  (ii)  During the Employment Period, and excluding any periods
of vacation and sick  leave  to  which the Executive is entitled, the Executive
agrees to devote reasonable attention  and time during normal business hours to
the  business  and affairs of the Company  and,  to  the  extent  necessary  to
discharge the responsibilities  assigned to the Executive hereunder, to use the
Executive's reasonable best efforts  to perform faithfully and efficiently such
responsibilities.  During the Employment  Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures,  fulfill  speaking  engagements  or
teach at educational institutions, and (C) manage personal investments, so long
as  such  activities do not significantly interfere with the performance of the
Executive's  responsibilities  as an employee of the Company in accordance with
this Agreement.  It is expressly  understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such  activities  (or  the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter  be  deemed  to interfere with the performance  of  the  Executive's
responsibilities to the Company.

            (b)   COMPENSATION.


                  (i)   BASE SALARY.      During  the  Employment Period, the 
Executive shall receive an annual base salary ("Annual Base Salary"), which 
shall be paid in equal installments on a monthly basis, at least equal to 
twelve times the highest monthly base salary paid or payable to the Executive
by the Company in  respect  of  the  twelve-month  period immediately preceding 
the month in which the Effective Date occurs.  During the Employment Period, 
the Annual Base Salary shall be reviewed at least annually and shall
be increased at any time and from time to time as shall be substantially 
consistent with increases  in base salary generally awarded in the ordinary 
course of business to other peer executives of the Company.  Any increase in 
Annual Base  Salary  shall not serve to limit or reduce any other obligation
to the Executive under this Agreement.  Annual Base Salary shall not be reduced
after any such increase and the term Annual Base Salary as utilized in this 
Agreement shall refer to Annual Base Salary as so increased.  

                  (ii)  ANNUAL  BONUS.   In addition to Annual Base Salary, the
Executive shall be awarded, for each fiscal  year  ending during the Employment
Period, an annual bonus (the "Annual Bonus") in cash  at  least  equal  to  the
average  annualized  (for  any  fiscal year consisting of less than twelve full
months or with respect to which the  Executive has been employed by the Company
for less than twelve full months) bonus paid or payable, including by reason of
any deferral, to the Executive by the  Company  in  respect of the three fiscal
years immediately preceding the fiscal year in which  the Effective Date occurs
(the "Recent Average Bonus").  Each such Annual Bonus shall  be  paid  no later
than  the  end  of the third month of the fiscal year next following the fiscal
year for which the Annual Bonus is awarded, unless the Executive shall elect to
defer the receipt of such Annual Bonus.

                  (iii)   INCENTIVE, SAVINGS RETIREMENT AND STOCK OPTION PLANS.
During the Employment Period, the Executive shall be entitled to participate in
all incentive, savings retirement  and  stock option plans, practices, policies
and programs applicable generally to other  peer executives of the Company, but
in  no event shall such plans, practices, policies  and  programs  provide  the
Executive  with  incentive opportunities (measured with respect to both regular
and  special  incentive  opportunities,  to  the  extent,  if  any,  that  such
distinction  is  applicable),  savings  opportunities  and  retirement  benefit
opportunities,  in  each  case, less favorable, in the aggregate, than the most
favorable of those provided  by the Company for the Executive under such plans,
practices, policies and programs  as  in  effect  at any time during the 90-day
period immediately preceding the Effective Date or  if  more  favorable  to the
Executive,  those  provided  generally  at any time after the Effective Date to
other executives of the Company.

                  (iv)  WELFARE BENEFIT PLANS.   During  the Employment Period,
the  Executive  and/or  the Executive's family, as the case may  be,  shall  be
eligible for participation  in  and  shall  receive  all benefits under welfare
benefit  plans,  practices,  policies  and  programs provided  by  the  Company
(including,  without  limitation,  medical, prescription,  dental,  disability,
salary continuance, employee life, group  life,  accidental  death  and  travel
accident  insurance  plans and programs) to the extent applicable generally  to
other peer executives  of  the  Company,  but  in  no  event  shall such plans,
practices, policies and programs provide the Executive with benefits  which are
less  favorable,  in  the  aggregate,  than  the  most favorable of such plans,
practices, policies and programs in effect for the Executive at any time during
the  90-day  period  immediately  preceding  the Effective  Date  or,  if  more
favorable to the Executive, those provided generally  at  any  time  after  the
Effective Date to other peer executives of the Company.

                  (v)   EXPENSES.   During the Employment Period, the Executive
shall be entitled to receive prompt reimbursement for all reasonable employment
expenses  incurred  by the Executive in  accordance  with  the  most  favorable
policies, practices and  procedures  of  the  Company  and  in  effect  for the
Executive  at  any  time  during  the  90-day  period immediately preceding the
Effective Date or, if more favorable to the Executive,  as  in effect generally
at any time thereafter with respect to other peer executives of the Company.

                  (vi)  FRINGE  BENEFITS.   During the Employment  Period,  the
Executive shall be entitled to fringe benefits  in  accordance  with  the  most
favorable  plans, practices, programs and policies of the Company in effect for
the Executive  at  any  time during the 90-day period immediately preceding the
Effective Date or, if more  favorable  to the Executive, as in effect generally
at any time thereafter with respect to other peer executives of the Company.

                  (vii)   OFFICE  AND SUPPORT  STAFF.   During  the  Employment
Period, the Executive shall be entitled  to  an office or offices of a size and
with furnishings, and to exclusive personal secretarial  and  other assistance,
at least equal to the most favorable of the foregoing provided to the Executive
by the Company at any time during the 90-day period immediately  preceding  the
Effective Date or, if more favorable to the Executive, as provided generally at
any time thereafter with respect to other peer executives of the Company.

                  (viii)VACATION.   During the Employment Period, the Executive
shall be entitled to paid vacation in accordance with the most favorable plans,
policies, programs and practices of the  Company as in effect for the Executive
at any time during the 90-day period immediately  preceding  the Effective Date
or,  if  more favorable to the Executive, as in effect generally  at  any  time
thereafter with respect to other peer executives of the Company.

5.          TERMINATION OF EMPLOYMENT

            (a)   DEATH   OR  DISABILITY.   The  Executive's  employment  shall
terminate  automatically upon  the  Executive's  death  during  the  Employment
Period.  If  the  Company  determines  in good faith that the Disability of the
Executive has occurred during the Employment Period (pursuant to the definition
of Disability set forth below), it may give  to the Executive written notice in
accordance with Section 12(b) of its intention  to  terminate  the  Executive's
employment.   In such event, the Executive's employment with the Company  shall
terminate effective  on  the  30th  day  after  receipt  of  such notice by the
Executive (the "Disability Effective Date"), provided that, within  the 30 days
after  such  receipt,  the  Executive  shall  not  have  returned  to full-time
performance  of  the  Executive's  duties.   For  purposes  of  this Agreement,
"Disability"  shall  mean  the  absence  of  the Executive from the Executive's
duties with the Company on a full-time basis for  180 consecutive business days
as a result of incapacity due to mental or physical illness which is determined
to  be  total  and  permanent by a physician selected by  the  Company  or  its
insurers  and  acceptable   to   the   Executive   or   the  Executive's  legal
representative  (such  agreement  as  to  acceptability  not  to   be  withheld
unreasonably).

            (b)   CAUSE.  The Company may terminate the Executive's  employment
during  the  Employment  Period  for  Cause.   For  purposes of this Agreement,
"Cause" shall mean (i) a material breach by the Executive  of  the  Executive's
obligations  under  Section 4(a) (other than as a result of incapacity  due  to
physical or mental illness) which is demonstrably willful and deliberate on the
Executive's part, which  is committed in bad faith or without reasonable belief
that such breach is in the  best  interests  of  the  Company  and which is not
remedied  in a reasonable period of time after receipt of written  notice  from
the Company  specifying such breach or (i) the conviction of the Executive of a
felony involving moral turpitude.

            (c)   GOOD  REASON.   The  Executive's employment may be terminated
during the Employment Period by the Executive for Good Reason.  For purposes of
this Agreement, "Good Reason" shall mean

                  (i)   the  assignment  to   the   Executive   of  any  duties
inconsistent  in  any respect with the Executive's position (including  status,
offices,   title   and    reporting   requirements),   authority,   duties   or
responsibilities as contemplated  by Sections 3 and 4(a) or any other action by
the Company which results in a diminution  in  such position, authority, duties
or responsibilities, excluding for this purpose  an isolated, insubstantial and
inadvertent action not taken in bad faith and which  is remedied by the Company
promptly after receipt of notice thereof given by the Executive;

                  (ii)  any failure by the Company to  comply  with  any of the
provisions   of  Section  4(b),  other  than  an  isolated,  insubstantial  and
inadvertent failure  not  occurring  in  bad faith and which is remedied by the
Company promptly after receipt of notice thereof given by the Executive;

                  (iii)  the Company's requiring  the  Executive to be based at
any office or location other than that described in Section 4(a)(i)(B);

                  (iv)   any  purported  termination  by  the  Company  of  the
Executive's employment otherwise than as expressly permitted by this Agreement;
or

                  (v)   any failure by the Company to comply  with  and satisfy
Section  11(c),  provided  that such successor has received at least ten  days'
prior written notice from the  Company  or the Executive of the requirements of
Section 11(c).

            For purposes of this Section  5(c), any good faith determination of
"Good  Reason" made by the Executive shall be  conclusive.   Anything  in  this
Agreement  to  the contrary notwithstanding, a termination by the Executive for
any  reason  during  the  six-month  period  immediately  following  the  first
anniversary of  the  Change of Control Date shall be deemed to be a termination
for Good Reason for all purposes of this Agreement.
            (d)   NOTICE  OF  TERMINATION.   Any termination by the Company for
Cause or by the Executive for Good Reason shall  be  communicated  by Notice of
Termination  to the other party hereby given in accordance with Section  12(b).
For purposes of  this  Agreement,  a  "Notice  of  Termination" means a written
notice which (i) indicates the specific termination provision in this Agreement
relied upon, (ii) to the extent applicable, sets forth in reasonable detail the
facts  and  circumstances  claimed to provide a basis for  termination  of  the
Executive's employment under  the  provision so indicated and (iii) if the Date
of Termination (as defined below) is  other  than  the  date of receipt of such
notice, specifies the termination date (which date shall  be  not  more than 15
days  after  the giving of such notice).  The failure by the Executive  or  the
Company to set  forth  in  the  Notice  of Termination any fact or circumstance
which contributes to a showing of Good Reason  or  Cause  shall  not  waive any
right  of the Executive or the Company  hereunder or preclude the Executive  or
the  Company  from  asserting  such  fact  or  circumstance  in  enforcing  the
Executive's or the Company's rights hereunder.

            (e)   DATE  OF TERMINATION.  "Date of Termination" means (i) if the
Executive's employment is  terminated  by  the  Company  for  Cause,  or by the
Executive for Good Reason, the date of receipt of the Notice of Termination  or
any  later  date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
Date of Termination  shall  be  the  date  on  which  the  Company notifies the
Executive  of  such  termination  and  (iii)  if the Executive's employment  is
terminated by reason of death or Disability, the  Date  of Termination shall be
the  date of death of the Executive or the Disability Effective  Date,  as  the
case may be.

6.          OBLIGATIONS OF THE COMPANY UPON TERMINATION

            (a)   GOOD  REASON; OTHER THAN FOR CAUSE, DEATH OR DISABILITY.  If,
during the Employment Period,  the  Company  shall  terminate  the  Executive's
employment other than for Cause or Disability or the Executive shall  terminate
employment for Good Reason:

                  (i)   the Company shall pay to the Executive in a lump sum in
cash  within  30  days  after  the  Date  of  Termination  the aggregate of the
following amounts.

                        A.    the sum of (1) the Executive's Annual Base Salary
through  the Date of Termination to the extent not theretofore  paid,  (2)  the
product of  (x)  the greater of (i) the Annual Bonus paid or payable, including
by reason of any deferral, to the Executive (and annualized for any fiscal year
consisting of less  than twelve full months or for which the Executive has been
employed for less than  twelve  full  months)  for  the most recently completed
fiscal year during the Employment Period, if any, and  (ii)  the Recent Average
Bonus  (such  greater amount shall be hereinafter referred to as  the  "Highest
Annual Bonus"),  and  (y)  a  fraction, the numerator of which is the number of
days in the current fiscal year  through  the  Date  of  Termination,  and  the
denominator of which is 365 and (3) any compensation previously deferred by the
Executive  (together  with  any  accrued  interest or earnings thereon) and any
accrued vacation pay, in each case to the extent  not theretofore paid (the sum
of  the  amounts  described in clauses (1), (2) and (3)  shall  be  hereinafter
referred to as the "Accrued Obligations"); and

                        B.    the  amount equal to the product of (1) three and
(2) the sum of (x) the Executive's Annual  Base  Salary  and  (y)  the  Highest
Annual Bonus; and

                        C.    a   separate   lump-sum  supplemental  retirement
benefit equal to the difference between (1) the actuarial equivalent (utilizing
for  this  purpose  the  actuarial assumptions utilized  with  respect  to  the
Company's Retirement Plan  (or  any  successor  plan  thereto) (the "Retirement
Plan") during the 90-day period immediately preceding the  Effective  Date)  of
the  benefit  payable  under  the  Retirement  Plan and any supplemental and/or
excess retirement plan of the Company providing benefits for the Executive (the
"SERP")  which  the  Executive  would  receive  if the  Executive's  employment
continued  at  the  compensation level provided for  in  Sections  4(b)(i)  and
4(b)(ii) for the remainder  of the Employment Period, assuming for this purpose
that all accrued benefits are  fully  vested  and that benefit accrual formulas
are no less advantageous to the Executive than  those  in effect during the 90-
day  period  immediately preceding the Effective Date, and  (2)  the  actuarial
equivalent (utilizing  for this purpose the actuarial assumptions utilized with
respect to the Retirement  Plan  during the 90-day period immediately preceding
the Effective Date) of the Executive's  actual  benefit  (paid  or payable), if
any,  under the Retirement Plan and the SERP; and

                  (ii)  for  the  remainder of the Employment Period,  or  such
longer period as any plan, program, practice or policy may provide, the Company
shall continue benefits to the Executive and/or the Executive's family at least
equal to those which would have been  provided  to  them in accordance with the
plans,  programs,  practices and policies described in  Sections  4(b)(iv)  and
4(b)(vi) if the Executive's  employment  had  not been terminated in accordance
with the most favorable plans, practices, programs  or  policies of the Company
as in effect and applicable generally to other executives  and  their  families
during  the 90-day period immediately preceding the Effective Date or, if  more
favorable  to the Executive, as in effect generally at any time thereafter with
respect to other  peer  executives of the Company and their families, provided,
however, that if the Executive  becomes reemployed with another employer and is
eligible to receive medical or other  welfare  benefits  under another employer
provided plan, the medical and other welfare benefits described herein shall be
secondary to those provided under such other plan during such applicable period
of  eligibility (such continuation of such benefits for the  applicable  period
herein  set  forth  shall  be  hereinafter  referred  to  as  "Welfare  Benefit
Continuation").   For purposes of determining eligibility of the Executive  for
retired benefits pursuant  to such plans, practices, programs and policies, the
Executive shall be considered  to  have  remained employed until the end of the
Employment Period and to have retired on the last day of such period; provided,
however, that the Executive shall be entitled  to  the  more  favorable  of the
retiree  benefits  in effect on the Date of Termination or the retiree benefits
in effect on the date  that  would  have  been  the last date of the Employment
Period if the Executive had remained employed; and

                  (iii)  to the  extent not theretofore  paid  or provided, the
Company  shall  timely  pay or provide to the Executive and/or the  Executive's
family any other amounts  or  benefits required to be paid or provided or which
the Executive and/or the Executive's  family is eligible to receive pursuant to
this Agreement and under any plan, program,  policy  or practice or contract or
agreement  of  the  Company  and  its affiliated companies  as  in  effect  and
applicable generally to other peer executives and their families during the 90-
day period immediately preceding the  Effective  Date  or, if more favorable to
the  Executive, as in effect generally thereafter with respect  to  other  peer
executives  of  the Company and their families (such other amounts and benefits
shall be hereinafter referred to as the "Other Benefits").

            (b)   DEATH.  If the Executive's employment is terminated by reason
of the Executive's  death  during  the  Employment Period, this Agreement shall
terminate without further obligations to  the Executive's legal representatives
under  this Agreement, other than for payment  of  Accrued  Obligations  (which
shall be  paid  to  the  Executive's estate or beneficiary, as applicable, in a
lump sum in cash within 30  days  of  the  Date  of Termination) and the timely
payment or provision of the Welfare Benefit continuation and Other Benefits.

            (c)   DISABILITY.  If the Executive's  employment  is terminated by
reason  of  the  Executive's  Disability  during  the  Employment Period,  this
Agreement shall terminate without further obligations to  the  Executive, other
than for payment of Accrued Obligations (which shall be paid to  the  Executive
in a lump sum in cash within 30 days of the Date of Termination) and the timely
payment or provision of the Welfare Benefit Continuation and other Benefits.

            (d)   CAUSE;  OTHER  THAN  FOR  GOOD  REASON.   If  the Executive's
employment  shall  be  terminated for Cause during the Employment Period,  this
Agreement shall terminate  without  further  obligations to the Executive other
than the obligation to pay to the Executive Annual Base Salary through the Date
of Termination plus the amount of any compensation  previously  deferred by the
Executive,  in  each  case to the extent theretofore unpaid.  If the  Executive
terminates employment during the Employment Period, other than for Good Reason,
this Agreement shall terminate  without  further  obligations to the Executive,
other than for Accrued Obligations and the timely payment or provision of Other
Benefits.  In such case, all Accrued Obligations shall be paid to the Executive
in a lump sum in cash within 30 days of the Date of Termination.

7.          NONEXCLUSIVITY OF RIGHTS

            Nothing in this Agreement shall prevent  or  limit  the Executive's
continuing  or  future  participation in any plan, program, policy or  practice
provided by the Company and  for  which  the  Executive  may qualify, nor shall
anything herein limit or otherwise affect such rights as the Executive may have
any contract or agreement with the Company.  Amounts which  are vested benefits
or which the Executive is otherwise entitled to receive under any plan, policy,
practice  or  program of or any contract or agreement with the  Company  at  or
subsequent to the  Date of Termination shall be payable in accordance with such
plan, policy, practice or program or contract or agreement except as explicitly
modified by this Agreement.

8.          FULL SETTLEMENT; RESOLUTION OF DISPUTES

            (a)   The Company's obligation to make the payments provided for in
this Agreement and otherwise  to perform its obligations hereunder shall not be
affected by any set-off, counterclaim,  recoupment,  defense  or  other  claim,
right or action which the Company may have against the Executive or others.  In
no event shall the Executive be obligated to seek other employment or take  any
other action by way of mitigation of the amounts payable to the Executive under
any  of  the  provisions  of  this Agreement and, except as provided in Section
6(a)(ii), such amounts shall not  be  reduced  whether  or  not  the  Executive
obtains other employment.  The Company agrees to pay promptly upon invoice,  to
the  full  extent  permitted  by  law,  all  legal  fees and expenses which the
Executive  may  incur  as a result of any contest (regardless  of  the  outcome
thereof)  by  the  Company,   the  Executive  or  others  of  the  validity  or
enforceability of, or liability  under,  any provision of this Agreement or any
guarantee of performance thereof (including  as  a result of any contest by the
Executive about the amount of any payment pursuant to this Agreement).

            (b)   If there shall be any dispute between  the  Company  and  the
Executive  (i) in the event of any termination of the Executive's employment by
the company,  whether  such  termination was for Cause, or (ii) in the event of
any termination of employment  by  the  Executive, whether Good Reason existed,
then, unless and until there is a final,  nonappealable  judgment by a court of
competent jurisdiction declaring that such termination was  for  Cause  or that
the determination by the Executive of the existence of Good Reason was not made
in good faith, the Company shall pay all amounts, and provide all benefits,  to
the Executive and/or the Executive's family or other beneficiaries, as the case
may  be,  that  the  Company  would  be  required to pay or provide pursuant to
Section 6(a) as through such termination were  by  the Company without Cause or
by the Executive with Good Reason; provided, however,  that  the  Company shall
not  be required to pay any disputed amounts pursuant to this paragraph  except
upon receipt  of  any undertaking by or on behalf of the Executive to repay all
such amounts to which the Executive is ultimately adjudged by such court not to
be entitled.

9.          CERTAIN ADJUSTMENTS

            (a)   For  purposes  of  this section, (i) A Payment shall mean any
payment or distribution in the nature  of compensation to or for the benefit of
Executive, whether paid or payable pursuant  to  this  Agreement  or  otherwise
(including  the  vesting  of  stock  options,  the  lapse  of  restrictions  on
restricted  stock  and any other events that result in a "payment in the nature
of compensation" within  the  meaning  of  Section 280G of the Internal Revenue
Code of 1986, as amended (the "Code")); (ii)  Agreement  Payment  shall  mean a
Payment  paid  or payable pursuant to this Agreement (disregarding this Section
9); (iii) Net After  Tax  Receipt shall mean the Present Value of a Payment net
of all taxes imposed on Executive  with  respect  thereto  under Sections 1 and
4999 of the Code determined by applying the highest marginal rate under Section
1  of  the  Code  which  applied  to  the  Executive's taxable income  for  the
immediately preceding taxable year; (iv) "Present  Value" shall mean such value
determined in accordance with Section 2870G(d)(4) of the Code; and (v) "Reduced
Amount" shall mean the largest aggregate amount of Payment  which  is less than
the sum of all Payments and if paid to the Executive would result in  aggregate
Net  After  Tax  Receipts which are equal to or greater than the Net After  Tax
Receipts which would  result  if the Executive were paid an amount equal to the
sum of the aggregate Payments.

                  Anything in this  Agreement  to the contrary notwithstanding,
in  the event it shall be determined that receipt  of  all  Agreement  Payments
would  subject  Executive  to  the  excise  tax  under Section 4999 of the Code
(together  with  any  interest or penalties imposed thereon,  "Excise  Tax")  a
determination shall be made whether there is a "Reduced Amount".  If there is a
Reduced Amount, the aggregate Payments shall be reduced to such Reduced Amount.

            (b)   All determinations  required to be made under this Section 9,
including whether there is a Reduced Amount, shall be made by KPMG Peat Marwick
(the "Accounting Firm") which shall provide  detailed  supporting  calculations
both to the Company and the Executive within 15 business days of the receipt of
notice  from the Executive that there has been a Payment, or such earlier  time
as is requested  by  the  Company.   In  the  event that the Accounting Firm is
serving as accountant or auditor for the individual,  entity or group effecting
the  Change  of  Control,  the  Executive  shall  appoint  another   nationally
recognized accounting firm to make the determinations required hereunder (which
accounting  firm  shall  then be referred to as the Accounting Firm hereunder).
All fees and expenses of the  Accounting  Firm  shall  be  borne  solely by the
company.   If  the Accounting Firm determines that no Excise Tax is payable  by
the Executive, it  shall  furnish  the  Executive  with  a written opinion that
failure to report the Excise Tax on the Executive's applicable  federal  income
tax  return  would  not  result  in  the  imposition of a negligence or similar
penalty.  If the Accounting Firm determines  that  aggregate Payments should be
reduced to the Reduced Amount, the Company shall promptly give Executive notice
to that affect and a copy of the detailed calculation  thereof.  As promptly as
practicable  following  such  determination,  the  Company  shall   pay  to  or
distribute for the benefit of Executive such Agreement Payments as are then due
to  Executive under this Agreement and shall promptly pay to or distribute  for
the benefit of Executive in the future such Agreement Payments as become due to
Executive under this Agreement.  Any determination by the Accounting Firm shall
be binding  upon  the  Company and the Executive.  While it is the intention of
the Company and the Executive to reduce the amounts payable or distributable to
Executive hereunder only  if  the aggregate Net After Tax Receipts to Executive
would thereby be increased, as  a  result of the uncertainty in the application
of  Section  4999  of the Code at the time  of  the  initial  determination  by
Accounting Firm hereunder,  it is possible that amounts will not have been paid
or distributed by the Company  to  or  for the benefit of Executive pursuant to
this   Agreement  which  should  not  have  been   so   paid   or   distributed
("Overpayment")  or  that  additional  amounts which will have not been paid or
distributed by the Company to or for the  benefit of Executive pursuant to this
Agreement  could  have been so paid or distributed  ("Underpayment"),  in  each
case, consistent with  the calculation of the Reduced Amount hereunder.  In the
event that Accounting Firm,  based either upon the assertion of a deficiency by
the Internal Revenue Service against  the Company or Executive which Accounting
Firm believes has a high probability of success, determines that an overpayment
has been made, any such Overpayment paid  or  distributed  by the Company to or
for the benefit of Executive shall be treated for all purposes  as  a  loan  to
Executive  which Executive shall repay to the Company together with interest at
the applicable  federal  rate  provided  for in Section 7872(f)(2) of the Code;
provided, however, that no such loan shall  be  deemed to have been made and no
amount shall be payable by executive to the Company  if  and to the extent such
deemed  loan  and  payment  would  not either reduce the amount  on  which  the
Executive is subject to tax under Section  1  and  Section  4999 of the Code or
generate a refund of such taxes.  In the event that Accounting Firm, based upon
controlling precedent or substantial authority, determines that an Underpayment
has occurred, any such Underpayment shall be promptly paid by the Company to or
for  the  benefit  of  the  Executive together with interest at the  applicable
federal rate provided for in Section 7872(f)(2) of the Code.

10.         CONFIDENTIAL INFORMATION

            The Executive shall hold in a fiduciary capacity for the benefit of
the Company all secret or confidential  information, knowledge or data relating
to the Company and its respective business,  which  shall have been obtained by
the Executive during the Executive's employment by the  Company and which shall
not  be  or  become public knowledge (other than by acts by  the  Executive  or
representatives  of  the  Executive  in  violation  of  this Agreement).  After
termination of the Executive's employment with the Company, the Executive shall
not, without the prior written consent of the Company or  as  may  otherwise be
required  by law or legal process, communicate or divulge any such information,
knowledge or  data to anyone other than the Company and those designated by it.
In no event shall  an  asserted  violation of the provisions of this Section 10
constitute a basis for deferring or  withholding  any amounts otherwise payable
to the Executive under this Agreement.

11.         SUCCESSORS

            (a)   This Agreement is personal to the  Executive  and without the
prior  written consent of the Company shall not be assignable by the  Executive
otherwise than by will or the laws of descent and distribution.  This Agreement
shall inure  to  the  benefit  of  and  be enforceable by the Executive's legal
representatives.

            (b)   This Agreement shall inure  to  the benefit of and be binding
upon the Company and its successors and assigns.

            (c)   The  Company will require any successor  (whether  direct  or
indirect,  by  purchase,  merger,   consolidation   or  otherwise)  to  all  or
substantially  all  of  the  business and/or assets of the  Company  to  assume
expressly and agree to perform  this  Agreement  in  the same manner and to the
same  extent  that  the  Company would be required to perform  it  if  no  such
succession had taken place.   As  used  in this Agreement, "Company" shall mean
the Company as hereinbefore defined and any  successor  to  its business and/or
assets  as  aforesaid  which  assumes and agrees to perform this  Agreement  by
operation of law, or otherwise.

12.         MISCELLANEOUS

            (a)   This  Agreement   shall  be  governed  by  and  construed  in
accordance with the laws of the State  of  New  Jersey,  without  reference  to
principles of conflict of laws.  The captions of this Agreement are not part of
the  provisions  hereof  and shall have no force or effect.  This Agreement may
not be amended or modified  otherwise  than  by a written agreement executed by
the parties hereto or their respective successors and legal representatives.

                          LEASE TERMINATION AGREEMENT

                  THIS  LEASE TERMINATION AGREEMENT ("Agreement"), made  as  of

                  WHEREAS,  by  Lease  Agreement,  dated  June   5,  1992  ("40

Kingsbridge Lease"), Landlord leased to Tenant the entire building  located  at

40  Kingsbridge Road, Piscataway, New Jersey ("40 Kingsbridge Building") for an

initial  term  of  fifteen  (15)  years  (the  20  Kingsbridge Lease and the 40

                  WHEREAS, concurrently with the execution  and delivery of the

Leases,  Tenant delivered to Landlord, as security for the performance  of  its

                  WHEREAS,  the  20  Kingsbridge  Lease  and the 40 Kingsbridge

the Leases is a default under the other Lease;

                  WHEREAS,  Tenant  is  in  default  under the  Leases  due  to

Tenant's abandonment of the 40 Kingsbridge building;

                  WHEREAS,  Landlord  and  Tenant desire  to  resolve  Tenant's

Building for purposes of removing its property including equipment.

            3.    Tenant hereby agrees to indemnify and hold Landlord  harmless

from  and  against  any suits, claims, proceedings, damages, liabilities and/or

other  compensation asserted by any broker, salesperson  or  finder  with  whom

Tenant has dealt in connection with the termination of the Leases.

            4.    This   Agreement  shall  be  governed  by  and  construed  in

accordance with the laws of the State of New Jersey.

            5.    This  Agreement   contains  all  of  the  understandings  and

agreements  of  the parties with respect  to  the  subject  matter  hereof  and

supersedes all other understandings and agreements of the parties, both written

and relating to the  subject  with hereof. This Agreement shall not be modified

arising out of Tenant's abandonment of the 40 Kingsbridge Building.

            8.    This  Agreement shall be binding upon and shall inure to  the

benefit of Landlord and Tenant  and  their  respective  successors, assigns and

                         OPTION AGREEMENT


               THIS OPTION AGREEMENT, ("Option Agreement"), dated as of April

1, 1995, between Holland Realty Corp., a Delaware corporation, having an

address c/o VIB Management, Inc., 712 Fifth Avenue, 19th Floor, New York, New

York 10019 ("Holland") and Enzon, Inc., a Delaware corporation, having an

office at 20 Kingsbridge Road, Piscataway, New Jersey 08854 ("Enzon").



                       W I T N E S S E T H :

               WHEREAS, Enzon is the tenant of the entire building located at

20 Kingsbridge Road, Piscataway, New Jersey designated as Block 503B, Lot 5B on

the Tax Map of the Township of Piscataway (the "Premises") pursuant to that

certain Lease Agreement of even date herewith between Holland and Enzon

("Lease");

               WHEREAS, Enzon desires to obtain an option to purchase the

Premises and Holland is willing to grant an option to purchase the Premises to

Enzon upon the terms and conditions hereinafter set forth;

               NOW, THEREFORE, for good and valuable consideration, the receipt

and sufficiency of which is hereby acknowledged, Holland and Enzon hereby agree

as follows:

          1.   Subject to the conditions set forth in this Option Agreement,

Enzon shall have the option to purchase fee title in and to the Premises

("Purchase Option") during calendar years 1996, 1997 and 1998 for the purchase

price ("Option Purchase Price") of (a) Three Million Five Hundred Thousand and

XX/100 ($3,500,000.00) Dollars if the closing and transfer of title occurs on

or before December 31, 1996, (b) Three Million Seven Hundred Fifty Thousand and

XX/100 ($3,750,000) Dollars if the closing and transfer of title occurs between

January 1, 1997 and December 31, 1997 and (c) Four Million and XX/100

($4,000,000.00) Dollars if the closing and transfer of title occurs between

January 1, 1998 and December 1, 1998. As consideration for Holland granting to

Enzon the Purchase Option, Enzon shall deliver to Holland on or before April

17, 1995 100,000 unregistered shares of common stock of Enzon ("Stock"). The

value of the Stock shall not be applied against the Option Purchase Price. In

the event Enzon shall fail to timely deliver the stock to Holland, such failure

shall constitute a default under that certain Indenture of Lease, of even date

herewith, between Holland, as Landlord, and Enzon, as Tenant, covering the

premises known as 20 Kingsbridge Road, Piscataway, New Jersey entitling Holland

to exercise any and all remedies available to Holland under said lease upon a

default by Enzon thereunder.

          2.   Enzon shall have the right to exercise the Purchase Option by

written notice ("Purchase Option Notice") delivered to Holland in accordance

with the terms hereof on or before December 31, 1998.

          3.   The date for the closing of title to the Premises shall be the

date which is the later of (a) forty-five (45) days after the date of mailing

of the Purchase Option Notice, or such earlier date as Enzon shall set forth in

the Purchase Option Notice or (b) ten (10) days after Holland shall have

received the ISRA Document (as hereinafter defined); provided that if the

closing is delayed solely due to the action or inactions of Holland, the

closing date shall be extended by the number of days attributable to such delay

and the Option Purchase Price will be the price that would have been in effect

but for such delay.

          4.   If, following the delivery of Enzon's Purchase Option Notice,

Enzon shall default in its obligation to purchase the Premises, the Purchase

Option shall forever terminate. If Holland defaults in its obligation to

transfer fee simple title to Enzon in accordance with the provisions of this

Article, Enzon shall have the right, as its sole and exclusive remedy, to

enforce specific performance of Holland's obligations hereunder but Enzon shall

have no right to make any claim for monetary damages as a result of any default

by Holland hereunder.

               5.   At the closing of title to the Premises (a) Enzon shall pay

the full amount of the Option Purchase Price to Holland by certified or bank

check made payable to the direct order of Holland, or as designated by Holland

or, at Holland's option by the wire transfer of federal funds to Holland's

account, or as designated by Holland, and (b) Holland shall deliver to Enzon a

bargain and sale deed with covenants against grantor's acts to the Premises, in

proper form for recording, duly executed and acknowledged, so as to convey to

Enzon fee simple title in and to the Premises, free and clear of all liens

(other than liens for Real Estate Taxes not yet due and payable) and

encumbrances, except for (x) those encumbrances which are of record as of the

date hereof, and (y) those liens and encumbrances which arise as a result of

the actions or inactions by Enzon, as tenant under the Lease. Holland shall

also deliver, at the closing, a corporate resolution authorizing the sale of

the Premises, a Title Affidavit in favor of Enzon's title insurance company and

a Certificate of Non-Foreign Status under Section 1445 of the Internal Revenue

Code. In addition, at the closing, Holland shall deliver to Enzon a letter from

the New Jersey Department of Environmental Protection and Energy ("NJDEPE")

that the Premises did not constitute an "industrial establishment" within the

meaning of the Environmental Cleanup Responsibility Act, N.J.S.A. 13:1K-6 ET

SEQ. and/or the Industrial Site Recovery Act ("ISRA"), or a "no further action

letter" without any deed restrictions from NJDEPE (as defined in ISRA) that the

Premises are not subject to the provisions of ISRA; or in the absence of either

of the foregoing, an approved "clean-up plan" (as defined in ISRA)

(collectively, the "ISRA Document"), provided, however, that if the cost to

Holland to implement the "clean-up" plan will, in Holland's reasonable

estimation, exceed Twenty-Five Thousand and XX/100 ($25,000.00) Dollars,

Holland shall have the right to terminate this Option Agreement and Enzon's

right to purchase the Premises. Notwithstanding anything herein to the

contrary, Holland shall have no obligation to comply with the deliveries

required under the preceding sentence if Holland is unable to comply with its

delivery obligation due to the acts or omissions of Enzon or its employees,

agents or contractors.

               Notwithstanding anything herein to the contrary, if the cost to

implement a "clean-up" plan exceeds Twenty-Five ($25,000.00) Dollars, Enzon

shall have the right to either (a) close title without any obligation on the

part of Holland to implement such "clean-up plan" in which event Enzon shall

receive a credit in the amount of Twenty-Five Thousand ($25,000.00) Dollars

against the Option Purchase Price or (b) agree to fund all costs of the

"clean-up plan" in excess of Twenty-Five Thousand ($25,000.00) Dollars in which

event the closing shall be postponed for a period not to exceed one (1) year in

order to implement such "clean-up plan". Enzon's right to exercise option (b)

in the preceding sentence is conditioned on the "clean-up plan" being able to

be completed within a period of one (1) year as determined by Holland's

environmental consultant and Enzon delivering to Holland cash or other

security, reasonably satisfactory to Holland, covering all costs of the

"clean-up plan" in excess of Twenty-Five Thousand ($25,000.00) Dollars.   Enzon

shall exercise its right contained in this paragraph within ten (10) days of

its receipt of Holland's notice of termination.

          6.   Except for an adjustment of fixed rent under the Lease, no

adjustments to the Option Purchase Price shall be made at the closing of title

to the Premises. Holland shall be responsible for the payment of any and all

transfer taxes, deed stamps, recording fees and any and all other taxes, costs

or expenses that may be payable in connection with the transfer of fee simple

title in and to the Premises to Enzon; but each party shall be responsible for

their own attorneys' fees incurred in connection with the closing of title to

the Premises.

          7.   Any termination, cancellation or surrender of Enzon's interest

in the Lease or the occurrence of a Bankruptcy Event (as hereinafter defined)

shall terminate Enzon's right to exercise the Purchase Option and to acquire

the Premises.

               Any of the following shall be a "Bankruptcy Event":

               (a)  Enzon's becoming insolvent, as that term is defined in

Title 11 of the United States Code, entitled Bankruptcy, 11 U.S.C. 101 et seq.

(the "Bankruptcy Code"), or under the insolvency laws of any State, District,

Commonwealth or Territory of the United States (the "Insolvency Laws");

               (b)  the appointment of a receiver or custodian for all or a

substantial portion of Enzon's property or assets if such appointment was

consented to or acquiesced to by Enzon, or the appointment of a receiver or

custodian for all or a substantial portion of Enzon's property or assets

without the consent or acquiescence of Enzon which is not dismissed within

sixty (60) days of the appointment, or the institution of a foreclosure action

upon all or a substantial portion of Enzon's real or personal property which is

not dismissed within sixty (60) days of the institution of such action;

               (c)  the filing of a voluntary petition by Enzon under the

provisions of the Bankruptcy Code or Insolvency Laws;

               (d)  the filing of an involuntary petition against Enzon as the

subject debtor under the Bankruptcy Code or Insolvency Laws, which is either

not dismissed within sixty (60) days of filing, or results in the issuance of

an order for relief against the debtor, whichever is later; or

               (e)  Enzon's making or consenting to an assignment for the

benefit of creditors or a common law composition of creditors.

          8.   If at any time during the period commencing as of the delivery

of Enzon's Purchase Option Notice, and ending at the closing of title to the

Premises, shall be either damaged or destroyed, or taken in condemnation or

pursuant to the exercise of the right of eminent domain, Enzon shall close

title to the Premises without any abatement or reduction of the Option Purchase

Price. At the closing of title to the Premises, Holland shall assign to Enzon,

in the case of damage or destruction to the Demised Premises, all of its

interest in the insurance proceeds for such damage or destruction together with

any rights against third parties with respect to such damage or destruction

and, in the case of a taking, all condemnation proceeds. Notwithstanding

anything herein to the contrary, in the event the cost to repair or restore the

damage or destruction shall exceed Two Hundred Thousand ($200,000.00) Dollars

as reasonably determined by an independent consultant designated by Holland or

if the insurance proceeds will be insufficient to restore the damage or

destruction, Enzon shall have the right to terminate this Option Agreement by

written notice of termination to Holland within fifteen (15) days of the damage

or destruction.

          9.   Any notices, correspondence or communications (collectively

"Notices") required or desired to be given under this Option Agreement shall be

in writing and shall be sent by United States registered or certified mail,

postage prepaid, return receipt requested, or by personal delivery, or by

overnight courier service with next business day delivery specified to the

                             ARTICLE V

Tenant shall exhibit to the Landlord receipted bills or other proof of payment.

Notwithstanding anything in this Section 7.01 and Section 7.03 to the contrary,
Tenant shall pay to Landlord together with each monthly installment of Basic
Rent, an additional amount sufficient to enable Landlord to pay, when due, all
of the Real Estate Taxes. The determination of the amount so payable and of the
fractional part thereof to be deposited with the Landlord each month so that
the aggregate of such deposits shall be sufficient for this purpose, shall be
made by the Landlord in its reasonable discretion. Such amounts shall be held
by he Landlord in trust and applied to the payment of the Real Estate Taxes.
All funds deposited by Tenant with Landlord hereunder shall be deposited in an
interest bearing account and any interest earned on such funds shall accrue for

Year (less the administrative fee) shall be retained by Landlord and shall be
applied towards Tenant's monthly installments of Real Estate Taxes for the
subsequent Lease Year. If one month prior to the due date of any Real Estate
Taxes amounts then on deposit with Landlord therefor shall be insufficient for
the payment of such obligation in full, Tenant within five (5) days after
demand, shall deposit the amount of the deficiency with Landlord. Landlord
shall not be required to segregate the amounts deposited with it under this
Section 7.01 but may commingle same with any other funds held by it. Upon
notice to Tenant, Landlord shall have the right, at any time and from time to
time, to elect not to escrow the Real Estate Taxes pursuant to the provisions
of this paragraph, whereupon the provisions of the preceding paragraph of this
Section 7.01 shall apply. Notwithstanding any such election to discontinue
escrowing the Real Estate Taxes, Landlord shall have the right, at any time and
from time to time, upon giving notice to Tenant to resume escrowing the Real
Estate Taxes in accordance with the provisions of this paragraph of Section
7.01.  In determining Tenant's montly escrow installment in respect of Real
Estate Taxes all assessments referred to in Section 7.03 shall be payable over
the maximum period permitted by law.

               Section 7.02. The Tenant shall not be required to pay any
estate, inheritance, devolution, succession, transfer, legacy or gift tax
charged against the Landlord or the estate or interest of the Landlord in the
Demised Premises or upon the right of any person to succeed to the same or any
part thereof by inheritance, succession, transfer or gift, nor any capital
stock tax or corporate franchise tax incurred by the Landlord, nor any income
tax upon or against the income of the Landlord (including any rental income
derived by the Landlord from the Demised Premises).

               Section 7.03. The Tenant shall pay all assessments that may be
imposed upon the Real Property by reason of any specific public improvement

installment thereof relating to a fiscal period in which the Term of this Lease
begins or ends shall be apportioned.

               Section 7.04. The Tenant, in its name or the Landlord's name,
shall have the right to contest, or review, by appropriate proceedings, in such
manner as it may deem suitable, at its own expense, and without expense to the
Landlord, any tax, assessment, water and sewer rents or charges, or other
charges payable by the Tenant pursuant to this Lease. Any refund resulting from
such contest or review shall be assigned to and belong to the Tenant and shall
be paid to the Tenant promptly upon its receipt by the Landlord. If the refund
relates to a tax year that is apportioned between the Landlord and the Tenant,
the refund shall be apportioned between the Landlord and the Tenant.

               Section 7.05. Notwithstanding anything contained herein to the
contrary, should Landlord's mortgagee require at any time, the maintenance of
an escrow reserve for the tax obligations of Tenant or for any other obligation
of Tenant as in this Lease contained, Tenant shall promptly pay to said
escrowee the required amount as the same may be periodically adjusted from time
to time.

               Section 7.06. As used in this Lease, Real Estate Taxes shall
mean the property taxes and assessments imposed upon the Demised Premises, or
upon the Rent (Basic and Additional), as such payable to Landlord, including
but not limited to, real estate, city, county, village, school and transit
taxes, or taxes, assessments or changes levied, imposed or assessed against the
Real Property including the Building, by any other taxing authority, whether
general or specific, ordinary or extraordinary, foreseen or unforeseen. If due
to a future change in the method of taxation, any franchise, income or profit
tax or other tax shall be levied against Landlord in substitution for, or in
lieu of, or in addition to, any tax which would otherwise constitute a Real
Estate Tax, such franchise, income or profit tax or other tax shall be deemed
to be a Real Estate Tax for the purPoses hereof.

               Section 7.07. Tenant agrees to pay the cost of all utilities,
including but not limited to gas and electricity charges for the Demised
Premises.


                           ARTICLE VIII

                             Insurance

               Section 8.01. Tenant's Insurance. (A) Tenant covenants and
represents, said representation being specifically designed to induce Landlord
to execute this Lease, that during the entire Term hereof, at its sole cost and
expense, Tenant shall obtain, maintain and keep in full force and effect, the
following insurance:

                    (1) "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 State of New Jersey, upon property of every
               description and kind owned by Tenant and located in the Demised
               Premises for which Tenant is legally liable or installed by or
               on behalf of Tenant, including by way of example and not by way
               of limitation, furniture, fixtures, fittings, installations and
               any other personal property, in an amount equal to the full
               replacement cost thereof. The Tenant may self-insure as to plate
               glass insurance.

                    (2) Comprehensive General Liability Insurance coverage, to
               include personal injury, bodily injury, broad form property
               damage, and contractual liability, naming Landlord and
               Landlord's mortgagee or trust deed holder and ground lessors (if
               any) as additional insureds in limits of not less than Three
               Million and 00/100 (S3,000,000.00) Dollars.

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

                    (4) Any other form or forms of insurance or increase in the
               limits of any of the aforesaid enumerated coverages or other
               forms of insurance as Landlord or the mortgagees or ground
               lessors (if any) of Landlord may reasonably require from time to
               time if in the reasonable opinion of Landlord or said mortgagees
               or ground lessors said coverage and/or limits become inadequate
               and less than that commonly maintained by prudent tenants in
               similar buildings in the area by tenants making similar uses.

                    (B) All property insurance policies shall be taken out with
insurers rated AX by Best Rating Service of Oldwick, New Jersey who are
licensed to do business in the State of New Jersey and shall be in form
satisfactory from time to time to Landlord. A policy or certificate evidencing
such insurance together with a paid bill shall be delivered to Landlord not
less than fifteen (15) days prior to the commencement of the Term hereof. Such
insurance policy or certificate will provide an undertaking by the insurers to
notify Landlord and the mortgagors or ground lessors (if any) of Landlord in
writing not less than thirty (30) days prior to any material change, reduction
in coverage, cancellation, or other termination thereof. Should a certificate
of insurance initially be provided, a policy shall be furnished by Tenant
within thirty (30) days of the Term's commencement. The aforesaid insurance
shall be written with no deductible.

                    (C) In the event of damage to or destruction of the Demised
Premises entitling Landlord or Tenant to terminate this Lease pursuant to
Article XI hereof, and if this Lease is so terminated, Tenant will immediately
pay to Landlord all of its insurance proceeds, if any, relating to the
leasehold improvements and alterations (but not Tenant's trade fixtures,
equipment, furniture and other personal property of Tenant in the Demised
Premises or those leasehold improvements and alterations to which Landlord has
consented and pursuant to which consent are required to be removed by Tenant at
the expiration or sooner termination of the Term) which have become Landlord's
property on installation or would have become Landlord's property at the Term's
expiration or sooner termination.

                    (D) Tenant agrees that it will not keep or use or offer for
sale (if sales of goods is a permitted use pursuant to this Lease) in or upon
the Demised Premises any article which may be prohibited by any insurance
policy in force from time to time covering the Demised Premises. Tenant shall
promptly comply with all reasonable requirements of the insurance authority or
of any insurer now or hereafter in effect relating to the Demised Premises.

                    (E) If any insurance policy carried by Landlord, as
provided in Section 8.02 hereof, shall be cancelled or cancellation shall be
threatened or the coverage thereunder reduced or threatened to be reduced in
any way by reason of the use or occupation of the Demised Premises or any part
thereof by Tenant or any assignee or sublessee of Tenant or anyone permitted by
Tenant to be upon the Demised Premises, and if Tenant fails to remedy the
conditions giving rise to said cancellation or threatened cancellation or
reduction in coverage on or before (i) forty-eight (48) hours after notice
thereof from Landlord, or (ii) prior to said cancellation or reduction becoming
effective, Tenant shall be in default hereunder and Landlord shall have all of
the remedies available to Landlord pursuant to this Lease.

               Section 8.02. Landlord's Insurance. Landlord covenants and
agrees that throughout the Term it will insure the Demised Premises [excluding
any property with respect to which Tenant is obligated to insure pursuant to
Subsection 8.01(A)(l) above] against damage by fire and standard extended
coverage perils for full replacement value and public liability insurance in
such reasonable amounts with such reasonable deductibles as required by any
mortgagee or ground lessor (if any), or if none, as would be carried by a
prudent owner of a similar building in the area. In addition, Landlord shall
maintain and keep in force and effect during the Term, rental income insurance
insuring Landlord against abatement or loss of Basic Rent, including items of
Additional Rent, in case of fire or other casualty similarly insured against,
in an amount at least equal to the Basic Rent and Additional Rent during, at
the minimum, one (1) Lease year hereunder. Landlord may, but shall not be
obligated to, take out and carry any other forms of insurance as it or the
mortgagee or ground lessor (if any) of the Real Property may reasonably require
or reasonably determine available. All insurance carried by Landlord on the
Demised Premises shall be reimbursed in full by Tenant, as Additional Rent.
Upon written request of Tenant, Landlord shall provide Tenant with copies of
certificates evidencing the insurance maintained by Landlord together with
copies of premium invoices with respect to such insurance coverage. Tenant
further acknowledges that the exculpatory provisions of this Lease as set forth
in Article XX and the provisions of this Subsection 8.02 as to Tenant's
insurance are designed to insure adequate coverage as to Tenant's property and
business without regard to fault and to avoid Landlord obtaining similar
coverage for said loss for its negligence or that of its agents, servants or
employees which would result in double coverage for the same perils which is
payable by Tenant. Landlord will not carry insurance of any kind on Tenant's
furniture or furnishings, or on any fixtures, equipment, appurtenances or
improvements of Tenant under this Lease, and Landlord shall not be obligated to
repair any damage thereto or replace the same.

               Section 8.03. Waiver of Claim/Waiver of Subrogation.
Notwithstanding anything contained herein to the contrary, in the event of any
loss or damage to the Building, the Premises and/or any contents, each party
waives all claims against the other for any such loss or damage and each party
shall look only to any insurance which it has obtained to protect against such
loss. Any policy or policies of fire, extended coverage or similar casualty
insurance, which either party obtains in connection with the Demised Premises,
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 said 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 insured affording it the same coverage as that provided the party
obtaining said coverage.

               Section 8.04. Indemnity. Tenant is and shall be in exclusive
control and possession of the Demised Premises as provided herein, and Landlord
shall not in any event whatsoever be liable for any injury or damage to any
property or to any person happening on or about the Demised Premises, or for
any injury or damage to the Demised Premises, nor to any property of Tenant, or
of any other person contained therein.

Tenant shall indemnify and save Landlord harmless against and from all
liabilities, claims, suits, fines, penalties, damages, losses, fees, costs and
expenses (including reasonable attorneys' fees) which may be imposed upon,
incurred by or asserted against Landlord by reason of:

                    (1)  Any work or thing done by Tenant, its agents or
               employees in, on or about the Demised Premises or any part
               thereof;

                    (2)  Any use, occupation, condition, operation by Tenant,
               its agents or employees of the Demised Premises or any part
               thereof or of any street, alley, sidewalk, curb, vault,
               passageway or space adjacent thereto or any occurrence on any of
               the same;

                    (3)  Any act or omission on the part of Tenant or any
               subtenant or any employees, licensees or invitees;

                    (4)  Any accident, injury (including death) or damage,
               unless caused by Landlord, its agents or employees, to any third
               party or property owned by someone other than Tenant and not
               under the care, custody or control of the Tenant occurring in,
               on or about the Demised Premises, or any part thereof or in, on
               or about any street, alley, sidewalk, curb, vault, passageway or
               space adjacent thereto; and

                    (5)  Any failure on the part of Tenant to perform or comply
               with any of the covenants, agreements, terms or conditions
               contained in this Lease.

               The provisions of this Section shall survive the expiration or
earlier termination thereof.

               Notwithstanding anything contained herein to the contrary,
Tenant shall have no obligation to indemnify Landlord and its agents from any
matter arising out of the negligence or intentional acts of Landlord or its
agents.

               Section 8.05. Escrow. In the event any mortgagee, ground lessor
or trust deed holder requires an escrow for insurance, taxes or any other
reoccurring charges, Tenant shall, on demand from Landlord, deposit the
required escrow as required by any of the aforesaid. Notwithstanding the above,
any payment by Tenant in excess of the actual charges for the above shall be
refunded to the Tenant.


                            ARTICLE IX

                              Repairs

               Section 9.01. The Tenant shall keep the Demised Premises,
including the sidewalks in front thereof, in good condition and repair, and
shall redecorate, paint and renovate the Demised Premises as may be necessary
to keep them in good condition and repair and good appearance. The Tenant shall
keep the Demised Premises and all parts thereof in a clean and sanitary
condition and free from trash, flammable material and other objectionable
matter. The Tenant shall keep the sidewalks, roadways and landscaped areas
forming part of the Demised Premises clean and free of obstructions, snow and
ice. Throughout the Term of this Lease, the Tenant, at its sole cost and
expense, will take good care of the Demised Premises and will keep the same in
good order and condition and make all necessary repairs and replacements
thereto, structural and non-structural, interior and exterior, ordinary and
extraordinary, foreseen and unforeseen.

               The Tenant shall replace, at the Tenant's expense, all glass in
and on the Demised Premises which may become broken after the date of Tenant's
occupancy. When used in this Article, the term "repairs" shall include all
necessary replacements and renewals. All repairs made by Tenant shall be equal
in quality and class to the original work. The Tenant shall quit and surrender
the Demised Premises at the end of the Term in good order and repair,
reasonable wear and tear excepted and in compliance with the requirements
stated herein and in a "broom-clean" condition, and shall, by way of example
and not by way of limitation, clean and reseal all exposed concrete floors.

               Should the Tenant fail to keep the Demised Premises in good
condition and repair, Landlord, after reasonable notice to Tenant (or without
notice in the case of an emergency), may, without being obliged, make the
repairs, and Tenant shall pay to Landlord, immediately upon demand, the cost
therefor, which shall constitute Additional Rent due hereunder and shall be
subject to all remedies by law or otherwise for the collection of Basic Rent
and Additional Rent; however, nothing herein shall be construed to impose a
duty on Landlord to mitigate its damages by undertaking any repair which is
Tenant's obligation.

               Section 9.02. The Tenant shall not make any alterations,
additions or improvements to the Demised Premises without the prior written
consent of the Landlord, which Landlord shall not unreasonably withhold or
delay. In the event Tenant has not received a response from Landlord to
Tenant's request for such alteration, addition or improvement, within ten (10)
days of Landlord's receipt of such request, Tenant shall so notify Landlord of
its failure to respond, and should Landlord still not respond to Tenant within
five (5) days of receipt of such Tenant's notice, Landlord's consent shall be
deemed granted. All erections, alterations, additions and improvements, whether
temporary or permanent in character, which may be made upon or to the Demised
Premises either by the Landlord or the Tenant, except furniture or movable
trade fixtures installed at the expense of the Tenant, shall be the property of
the Landlord and shall remain open and be surrendered with the Demised Premises
as a part thereof at the expiration or sooner termination of this Lease,
without compensation to the Tenant; or, in the alternative and at the direction
of Landlord, Tenant shall remove all or so much of the property therefrom as
directed or such property shall be conclusively deemed abandoned and may be
removed by Landlord, and Tenant shall reimburse Landlord for the cost of such
removal. Landlord may have any such property stored at Tenant's risk and
expense. Landlord shall notify Tenant at the time of its consent, as to whether
it will require that Tenant remove, at the expiration or sooner termination of
the Lease Term, any erections, alterations, additions or improvements made by
Tenant, and restore the Demised Premises to its preexisting condition and that
the Tenant use contractors approved by Landlord.

               Notwithstanding anything contained herein to the contrary,
Tenant may, without the need for obtaining Landlord's prior written consent,
make alterations, additions and improvements within the Premises which do not
affect the Building Systems (i.e. heating, ventilating, plumbing, electrical or
other utilities) or which do not affect any structural portion of the Building,
provided said alteration, addition and/or improvement does not exceed the sum
of Forty Thousand and 00/100 ($40,000.00) Dollars in the aggregate in any one
(1) Lease year. Tenant shall, however, as to said alterations, additions and/or
improvements not requiring Landlord's consent, provide Landlord with reasonable
prior notice of its intention to perform such alterations, together with
information as to the nature of said alterations, additions and/or
improvements, including but not limited to plans and specifications.


                             ARTICLE X

                  Tenant's Additional Obligations

               Section 10.01. Notwithstanding anything contained herein to the
contrary, during the Lease Term, Tenant agrees to maintain and repair and
replace, at its sole cost and expense, if necessary: (i) the roof; and (ii) the
parking lot, sidewalks and curbs. With respect to maintenance and repair of the
heating, ventilating and air conditioning ("HVAC") system servicing the Demised
Premises, Tenant shall, at its sole cost and expense, purchase a maintenance
and service contract, each Lease Year during the Term. Landlord shall have the
right to review and approve (which approval shall not be unreasonably withheld
or delayed) said maintenance and service contract and the contractor. Any items
of maintenance and repair to the HVAC system not covered by said maintenance
and service contract and/or any required replacement of all or a portion of
said HVAC system (as determined by Landlord in its sole but reasonable
judgment) shall be Tenant's responsibility, at its sole cost and expense.
Additionally, during the Lease Term, Tenant hereby agrees, at its own cost and
expense, to maintain and repair, when necessary, the Building Structure, which,
for the purposes hereof, shall be the footings, foundation, the steel
supporting columns, and exterior walls and to maintain, repair and/or replace,
at its own cost and expense the electrical transformer servicing the Demised
Premises and plumbing supply lines to the Building. Tenant shall purchase a
maintenance and service contract for the roof in accordance with the
requirements set forth above as to maintenance and service contract for the
HVAC system. Tenant shall promptly deliver to Landlord a copy of the
maintenance and service contracts for the HVAC system and the roof.  Landlord
shall assign to Tenant all existing warranties and guaranties relating to the
Demised Premises and its systems.

                            ARTICLE XI

                             Casualty

               Section 11.01. If the Demised Premises or the Building is
damaged or destroyed by fire, explosion, the elements or otherwise during the
Term so as to render the Demised Premises wholly untenantable or unfit for
occupancy, or should the Demised Premises be so badly injured that the same
cannot be repaired within one hundred eighty (180) days from the happening of
such injury [as determined by Landlord's architect or engineer by notice to
Landlord and Tenant within thirty (30) days of the date of the casualty], then,
and in such case, the Term hereby created shall, at the option of either the
Landlord or the Tenant terminate upon the giving of a notice of termination. If
a notice of termination is given, the Term of this Lease shall terminate
effective as of the date of such damage or destruction, and the Tenant shall
immediately surrender the Demised Premises and all the Tenant's interest
therein to the Landlord, and pay Basic Rent and Additional Rent to the time of
such damage or destruction, and the Landlord may re-enter and repossess the
Demised Premises discharged from this Lease and may remove all parties
therefrom.

               Section 11.02. Should the Demised Premises be rendered
untenantable and unfit for occupancy, but yet be repairable within one hundred
eighty (180) days from the happening of said injury [as determined by
Landlord's architect or engineer within thirty (30) days of the date of the
casualty], the Landlord will, provided the mortgagee makes the proceeds of any
casualty insurance required to be carried pursuant to this Lease available to
the Landlord to restore and further provided that the insurance proceeds so
received are adequate to restore the Building and the Demised Premises, enter
and repair the same with reasonable speed, and the Basic Rent and Additional
Rent shall not accrue after said injury or while such repairs are being made,
but shall recommence immediately after such repairs shall be completed;
provided that Landlord has delivered to Tenant a certificate of occupancy as
required by local law. Landlord shall endeavor to provide Tenant with thirty
(30) days prior notice of the estimated date of completion of such repairs.

               Section 11.03. If the Demised Premises shall be so slightly
injured as not to be rendered untenantable and unfit for occupancy, the
Landlord shall repair the same with reasonable promptness and the Basic Rent
and Additional Rent accrued and accruing shall not cease or terminate. The
Tenant shall immediately notify the Landlord in case of fire or other damage to
the Demised Premises.

               Section 11.04. Notwithstanding anything to the contrary in
Section 11.01, neither the Landlord nor the Tenant shall have any option to
terminate this Lease upon the happening of an injury referred to in Section
11.01, provided: (i) that the happening of such injury occurs at a time when
the unexpired Term of this Lease is two (2) years or more; (ii) further
provided that the mortgagee makes the proceeds of any casualty insurance
required to be carried pursuant to this Lease available to Landlord to restore;
and (iii) further provided that the insurance proceeds so received are adequate
to restore the Building and the Demised Premises. In such event, the Landlord
shall repair the Demised Premises, even to the extent of rebuilding the
Building if necessary, subject, however, to the receipt of sufficient insurance
proceeds. The Landlord shall promptly enter and repair the Demised Premises
with reasonable speed, making due allowance for conditions beyond the
Landlord's control, including but not limited to time lost in adjusting
insurance claims and strikes, and the Basic Rent and Additional Rent shall not
accrue after such injury and while repairs are being made, provided Landlord
receives the proceeds of rent insurance maintained by the Tenant, but shall
recommence immediately after said repairs shall be completed and the Landlord
delivers possession thereof to the Tenant. Landlord shall have no obligation to
repair or restore Tenant's improvements.

               Notwithstanding anything contained herein to the contrary, in
the event Landlord shall commence the restoration of the Demised Premises in
accordance with this Section 11.04, and if Tenant's acts or omissions, or those
of its agents, servants, or employees did not cause the casualty, then unless
Landlord restores the Demised Premises within one hundred eighty (180) days of
the date of the casualty, as said period is extended by Force Majeure, however
in no event beyond two hundred seventy (270) days from the date of the
casualty, Tenant shall have the right to terminate this Lease upon thirty (30)
days' prior notice to Landlord of its intent so to do, which notice shall be
given no earlier than said one hundred eightieth (180th) day as extended by
Force Majeure, but in no event beyond said two hundred seventieth (270th) day,
unless Landlord completes said restoration within the thirty (30) day period
similarly extended by Force Majeure but not beyond two hundred seventy (270)
days from the date of the casualty. Notwithstanding the foregoing, if, during
said restoration, Landlord's architect or engineer determines that the Premises
will not be restored within one hundred eighty (180) days of the date of the
casualty, subject to Force Majeure [but not beyond two hundred seventy (270)
days from the date of the casualty], then Landlord shall so notify Tenant and
Tenant shall have the right to terminate this Lease on thirty (30) days' notice
to Landlord of its intent to do so, unless Landlord completes said restoration
within said thirty (30) day period, similarly extended for Force Majeure.


                            ARTICLE XII

                           Condemnation

               Section 12.01. If Tenant's use of the Demised Premises is
materially affected due to a taking under any power of eminent domain or
condemnation then, at the option of the Tenant, to be exercised in writing
within thirty (30) days of the taking of title thereto, this Lease shall expire
within thirty (30) days of the date of such notice and the Basic Rent and any
Additional Rent herein reserved shall be apportioned as of that date. However,
if the Tenant does not exercise the aforementioned option, or if the taking
does not materially affect the Tenant's use of the Demised Premises, this Lease
shall not expire but the Basic Rent and Additional Rent shall be equitably
apportioned. If the Landlord and the Tenant fail to agree upon an equitable
apportionment, the Basic Rent and Additional Rent for the Building, after such
taking, shall be determined in accordance with the Commercial Rules of the
American Arbitration Association of Somerset, New Jersey, and the arbitrator
shall be empowered to assess the costs and expenses of the proceedings as part
of the determination. Pending such determination the Tenant shall pay, on
account of the Basic Rent and Additional Rent, such proportion of the Basic
Rent and Additional Rent reserved in this Lease as the total area of the
Building after the taking bears to the total area of the Building before the
taking, subject to adjustment in accordance with the arbitrator's award. If the
Landlord can, after such taking, construct an addition to the remaining
Building so as to restore all of the Building area and Building facilities
theretofore taken, the Landlord shall, subject to the adequacy of the
condemnation award and to the mortgagee making the same available to the
Landlord, promptly construct such addition and restore such facilities so taken
and upon the completion of such restoration, the full Basic Rent and Additional
Rent reserved by this Lease shall be reinstated, as of the date of such
restoration, and, if the Tenant is able to occupy and use the Building, the
proportionate Basic Rent and Additional Rent shall be paid by the Tenant as
herein provided, during the period between the taking and the restoration of
the Building and facilities. No part of any award shall belong to the Tenant
except that nothing contained herein is intended to affect or limit the
Tenant's separate claim for fixtures or other improvements owned by Tenant
provided the same does not diminish the Landlord's award. It is expressly
understood and agreed that the provisions of this Article XII shall not be
applicable to any condemnation or taking for governmental occupancy for a
limited period of time, and this Lease shall be and remain unaffected by such
condemnation or taking and the Tenant shall continue to be responsible for all
of its obligations hereunder and Tenant shall continue to pay the Basic Rent
and Additional Rent as provided in the Lease, provided in the event of any such
condemnation or taking Tenant shall be entitled to appear, claim, prove and
receive any award; but if the period of temporary use or occupancy extends
beyond the expiration date, Landlord shall be entitled to appear, claim, prove
and receive the entire award as represents the costs of restoration to the
Demised Premises and the portion of any such award allocable to the period
following the expiration date. To the extent Landlord receives any award for
loss of Tenant's rental or for the temporary use and occupancy of the Demised
Premises attributable to any portion of the Term hereof, Landlord agrees to
credit same against the Basic Rent and Additional Rent and otherwise payable by
Tenant hereunder. For purposes of this Section 12.01, a "limited period of
time" shall be deemed to mean six (6) months or less.

               Section 12.02. Tenant agrees to execute and deliver any
instruments, at the expense of Landlord, as may be reasonably necessary or
required to expedite any condemnation proceeding or to effectuate a proper
transfer of title to such governmental or other public authority, agency, body
or public utility seeking to take or acquire the Demised Premises or any
portion thereof. The Tenant covenants and agrees to vacate the Demised Premises
in the event the Lease is terminated as a result of condemnation and to remove
all of Tenant's personal property therefrom in accordance with the terms of
this Lease and deliver up peaceably possession thereof to the Landlord or to
such other party designated by Landlord by written notice in the condition
provided for in the Lease. In the event that the Lease is terminated all
obligations of the parties (except those obligations accruing prior to the
termination date and those which by the terms of this Lease survive
termination) shall cease as of such taking. Landlord and Tenant each agree to
provide prompt notice to the other of any taking or proposed taking of the
Demised Premises or any part thereof.

                           ARTICLE XIII

                    Compliance With Laws, Etc.

               Section 13.01. The Tenant shall not do or permit anything to be
done in the Demised Premises which shall constitute a public nuisance or which
will conflict with the regulations of the Fire Department or with any insurance
policy upon said improvements or any part thereof.

               Section 13.02. The Tenant shall, at its own expense, obtain all
necessary environmental and operating permits and comply with all requirements
of law and with all ordinance or orders, rules and regulations of any state,
municipal or other public authority affecting the Demised Premises and with all
requirements of the Fire Insurance Exchange or similar body, and of any
liability insurance company insuring the Landlord against liability for
accidents in or connected with the Demised Premises including, but not limited
to laws, ordinance, orders, rules and regulations which apply to the interior
or exterior of the Demised Premises, the structural or nonstructural parts
thereof, and to make all improvements and repairs required by such laws,
ordinances, orders, rules and regulations, ordinary or extraordinary, foreseen
or unforeseen.

               Section 13.03. (A) Tenant acknowledges the existence of
environmental laws, rules and regulations, including but not limited to the
provisions of IRA, as hereinafter defined. Tenant shall comply with any and all
such laws, rules and regulations.

                    (B) Tenant hereby agrees to execute such documents as
Landlord reasonably deems necessary and to make such applications as Landlord
reasonably requires to assure compliance with IRA. Tenant shall bear all costs
and expenses incurred by Landlord associated with any required ISRA compliance
resulting from Tenant's use of the Demised Premises including but not limited
to state agency fees, engineering fees, clean-up costs, filing fees and
suretyship expenses. As used in this Lease, IRA compliance shall include
applications for determinations of nonapplicability by the appropriate
governmental authority. The foregoing undertaking shall survive the termination
or sooner expiration of the Lease and surrender of the Demised Premises and
shall also survive sale, or lease or assignment of the Demised Premises by
Landlord. Tenant agrees to indemnify and hold Landlord harmless from any
violation of IRA occasioned by Tenant's use of the Demised Premises. The Tenant
shall immediately provide the Landlord with copies of all correspondence,
reports, notices, orders, findings, declarations and other materials pertinent
to the Tenant's compliance and the requirements of the New Jersey Department of
Environmental Protection and Energy ("NJDEPE") under IRA as they are issued or
received by the Tenant

                    (C) As used herein, Hazardous Substances shall be defined
as any "hazardous chemical", "hazardous substance" or similar term as defined
in the Comprehensive Environmental Responsibility Compensation and Liability
Act, as amended (42 U.S.C. 9601, et seq.), the New Jersey Environmental Cleanup
Act, as amended, N.J.S.A. 13:lK-6 ET SEQ. and/or the Industrial Site Recovery
Act ("ISRA"), the New Jersey Spill Compensation and Control Act, as amended,
N.J.S.A. 58:10-23.11b, ET SEA., any rules or regulations promulgated
thereunder, or in any other applicable federal, state or local law, rule or
regulation dealing with environmental protection. It is understood and agreed
that the provisions contained in this Section shall be applicable
notwithstanding the fact that any substance shall not be deemed to be a
Hazardous Substance at the time of its use by the Tenant but shall thereafter
be deemed to be a Hazardous Substance.

                    (D) In the event Tenant fails to comply with ISRA as stated
in this Section or any other governmental law as of the termination or sooner
expiration of the Lease and as a consequence thereof Landlord is unable to rent
the Demised Premises, then the Landlord shall treat the Tenant as one who has
not removed at the end of its Term, and thereupon be entitled to all remedies
against the Tenant provided by law in that situation including a monthly rental
of two hundred (200%) percent of the Monthly Basic Rent for the last month of
the Term of this Lease or any renewal term, payable in advance on the first day
of each month, until such time as Tenant provides Landlord with a negative
declaration or confirmation that any required clean-up plan has been
successfully completed.

                    (E) Tenant agrees that Tenant, its agents and contractors,
licensees, or invitees shall not handle, use, manufacture, store or dispose of
any Hazardous Substances, as hereinafter defined, on, under, or about the
Demised Premises, without Landlord's prior written consent (which consent shall
not be unreasonably withheld as long as Tenant demonstrates and documents to
Landlord's reasonable satisfaction (i) that such Hazardous Substances (a) are
necessary or useful to Tenant's business; and (b) will be used, kept, and
stored in compliance with all laws relating to any Hazardous Substances so
brought or used or kept in or about the Demised Premises; and (ii) that Tenant
will give all required notices concerning the presence in or on the Demised
Premises or the release of such Hazardous Substances from the Demised Premises)
provided that Tenant may handle, store, use or dispose of products containing
small quantities of Hazardous Substances, which products are of a type
customarily found in office and households (such as aerosol cans containing
insecticides, toner for copies, paints, paint remover, and the like), provided
further that Tenant shall handle, store, use and dispose of any such Hazardous
Substances in a safe and lawful manner and shall not allow such Hazardous
Substances to contaminate the Demised Premises or the environment.

                    (F) Tenant further agrees that Tenant will not permit any
substance suspected of causing cancer or reproductive toxicity to come into
contact with groundwater under the Demised Premises. Any such substance coming
into contact with groundwater shall be considered a Hazardous Substance for
purposes of this Section.

                    (G) (i) Notwithstanding the provisions of Section 13.03(E),
Tenant may handle, store, and use Hazardous Substances, limited to the types,
amounts, and use identified in the Hazardous Substances Exhibit attached
hereto. If no Hazardous Substances Exhibit is attached to this Lease, then this
Section 13.03(G) shall be of no force and effect. Tenant hereby certifies to
Landlord that the information provided by Tenant pursuant to this Section is
true, correct, and complete. Tenant covenants to comply with the use
restrictions shown on the attached Hazardous Substances Exhibit. Tenant's
business and operations, and more especially its handling, storage, use and
disposal of Hazardous Substances shall at all times comply with all applicable
laws pertaining to Hazardous Substances. Tenant shall secure and abide by all
permits necessary for Tenant's operations on the Demised Premises. Tenant shall
give or post all notices required by all applicable laws pertaining to
Hazardous Substances. If Tenant shall at any time fail to comply with this
Section, Tenant shall immediately notify Landlord in writing of such
noncompliance.

                         (ii) Tenant shall provide Landlord with copies of all
Material Safety Data Sheets (as required by the Occupational Safety and Health
Act) relating to any Hazardous Substances to be used, kept, or stored at or on
the Demised Premises, at least thirty (30) days prior to the first use,
placement, or storage of such Hazardous Substance on the Demised Premises.
Landlord shall have ten (10) days following delivery of such Material Safety
Data Sheets to approve or forbid, in its sole discretion subject to the
limitation contained in Section 13.03(E) above, such use, placement, or storage
of a Hazardous Substance on the Demised Premises.

                         (iii) Tenant shall not store hazardous wastes on the
Demised Premises for more than ninety (90) days; "hazardous waste" has the
meaning given it by the Resource Conservation and Recovery Act of 1976, as
amended. Tenant shall not install any underground or aboveground storage tanks
on the Demised Premises. Tenant shall not dispose of any Hazardous Substance or
solid waste on the Demised Premises. In performing any alterations of the
Demised Premises permitted by the Lease, Tenant shall not install any Hazardous
Substance in the Demised Premises without the specific consent of Landlord
attached as an Exhibit to this Section.

                         (iv) Any increase in the premium for necessary
insurance on the Demised Premises which arises from Tenant's use and/or storage
of Hazardous Substances shall be solely at Tenant's expense. Tenant shall
procure and maintain at its sole expense such additional insurance as may be
necessary to comply with any requirement of any federal, state or local
governmental agency with jurisdiction.

                    (H) If Landlord, in its sole discretion, believes that the
Demised Premises or the environment have become contaminated with Hazardous
Substances that must be removed under the laws of the State where the Demised
Premises are located, in breach of the provisions of this Lease, Landlord, in
addition to its other rights under this Lease, may enter upon the Demised
Premises and obtain samples from the Demised Premises, including without
limitation, the soil and groundwater under the Demised Premises, for the
purposes of analyzing the same to determine whether and to what extent the
Demised Premises or the environment have become so contaminated. Tenant shall
reimburse Landlord for the costs of any inspection, sampling and analysis that
discloses contamination for which Tenant is liable under the terms of this
Section. Tenant may not perform any sampling, testing, or drilling to locate
any Hazardous Substances on the Demised Premises without Landlord's prior
written consent.

                    (I) Without limiting the above, Tenant shall reimburse,
defend, indemnify and hold Landlord harmless from and against any and all
claims, losses, liabilities, damages, costs and expenses, including without
limitation, loss of rental income, loss due to business interruption, and
attorneys' fees and costs, arising out of or in any way connected with the use,
manufacture, storage, or disposal of Hazardous Substances by Tenant, its agents
or contractors on, under or about the Demised Premises, including, without
limitation, the costs of any required or necessary investigation, repair,
clean-up or detoxification and the preparation of any closure or other required
plans in connection herewith, whether voluntary or compelled by governmental
authority. The indemnity obligations of Tenant under this clause shall survive
any termination of the Lease. At Landlord's option, Tenant shall perform any
required or necessary investigation, repair, clean-up, or detoxification of the
Demised Premises required under any applicable federal or state statute or
regulation. In such case, Landlord shall have the right, in its sole
discretion, to approve all plans, consultants, and clean-up standards. Tenant
shall provide Landlord on a timely basis with (i) copies of all documents,
reports, and communications with governmental authorities; and (ii) notice and
an opportunity to attend all meetings with regulatory authorities. Tenant shall
comply with all notice requirements and Landlord and Tenant agree to cooperate
with governmental authorities seeking access to the Demised Premises for
purposes of sampling or inspection. No disturbance of Tenant's use of the
Demised Premises resulting from activities conducted pursuant to this Section
shall constitute an actual or constructive eviction of Tenant from the Demised
Premises. In the event that such clean-up extends beyond the termination of the
Lease, Tenant's obligation to pay Basic Rent (including Additional Rent) shall
continue until such clean-up is completed and any certificate of clearance or
similar document has been delivered to Landlord. Basic Rent during such
holdover period shall be at market rent; if the parties are unable to agree
upon the amount of such market rent, then Landlord shall have the option of (a)
increasing the Basic Rent for the period of such holdover based upon the
increase in the cost of living (as determined by the Consumer Price Index for
the New York Metropolitan Area) from the third (3rd) month preceding the
commencement date to the third (3rd) month preceding the start of the holdover
period, using such indices and assumptions and calculations as Landlord in its
sole reasonable judgment shall determine are necessary; or (b) having Landlord
and Tenant each appoint a qualified MAI appraiser doing business in the same
area; in turn, these two independent MAI appraiser shall appoint a third MAI
appraiser and the majority shall decide upon the fair market rental for Demised
Premises as of the expiration of the then current Term. Landlord and Tenant
shall equally share in the expense of the appraisal except that in the event
the Basic Rent is found to be within fifteen (15%) percent of the original rate
quoted by Landlord, then Tenant shall bear the full cost of all the appraisal
process. In no event shall the Basic Rent be subject to determination or
modification by any person, entity, court, or authority other than as set forth
expressly herein, and in no event shall the rent for any holdover period be
less than the Basic Rent due in the preceding period.

                    (J) Notwithstanding anything set forth in the Lease, Tenant
shall only be responsible for contamination of Hazardous Substances or any
clean-up resulting directly therefrom, resulting directly or indirectly from
matters occurring or Hazardous Substances deposited (other than by contractors,
agents or representatives controlled by Landlord) during the Lease Term, and
any other period of time during which Tenant is in actual or constructive
occupancy of the Demised Premises. Tenant shall take reasonable precautions to
prevent the contamination of the Demised Premises with Hazardous Substances by
third parties.

                    (K) It shall not be unreasonable for Landlord to withhold
its consent to any proposed assignment or sublease if (i) the proposed
assignee's or sublessee's anticipated use of the Demised Premises involves the
generation, storage, use, treatment or disposal of Hazardous Substances; (ii)
the proposed assignee or sublessee has been required by any prior landlord,
lender or governmental authority to take remedial action in connection with
Hazardous Substances contaminating the property if the contamination resulted
from such assignee's or sublessee's actions or use of the property in question;
or (iii) the proposed assignee or sublessee is subject to an enforcement order
issued by any governmental authority in connection with the use, disposal, or
storage of a Hazardous Substance.

                    (L) Any of Tenant's insurance insuring against claims of
the type dealt with in this Section shall be considered primary coverage for
claims against the Demised Premises arising out of or under this Section.

                    (M) In the event (i) any transfer of Tenant's interest
under this Lease; or (ii) the termination of this Lease, by lapse of time or
otherwise, Tenant shall be solely responsible for compliance with any and all
then effective Federal, state or local laws concerning (a) the physical
condition of the Demised Premises, Building, or Building Area; or (b) the
presence of hazardous or toxic materials in or on the Demised Premises,
Building, or Building Area (for example, the New Jersey Environmental Cleanup
Responsibility Act, or similar applicable state laws), including, but not
limited to, any reporting or filing requirements imposed by such laws. Tenant's
duty to pay Basic Rent and Additional Rent shall continue until the obligations
imposed by such laws are satisfied in full and any certificate of clearance or
similar document has been delivered to Landlord. The Basic Rent and Additional
Rent required to be paid by Tenant in accordance with this Subsection 13.03(M)
during that period beyond the termination or sooner expiration of this Lease
shall be as described in Subsection 13.03(D).

                    (N) All consents given by Landlord pursuant to this Section
shall be in writing and shall be considered amendments to this Lease.

                    (O) Landlord represents to Tenant that (i) it has received
no notice of a violation of any environmental law, rule or regulation
including, but not limited to, ISRA with respect to the Demised Premises; and
(ii) to its actual knowledge, it is not aware of any violation of such laws,
rules or regulations with respect to the Demised Premises.

               Section 13.04. Notwithstanding anything contained herein to the
contrary, Tenant shall have no responsibility for any cost or expense for any
Hazardous Substance or environmental condition determined to have been in
existence prior to its initial occupancy of the Demised Premises.


                            ARTICLE XIV

                           Subordination

               Section 14.01. This Lease is and shall be subject and
subordinate to all present and future first mortgages or first deeds of trust
affecting the Demised Premises. The Tenant shall execute, any instrument which
may be deemed necessary or desirable by the Landlord to further effect or to
evidence the subordination of this Lease to any such first mortgage or first
deed of trust. The Landlord may assign this Lease to any such first mortgagee
or first trust deed holder in connection with any such lien superior to this
Lease, and the Tenant shall execute, at no expense to the Tenant, any
instrument which may be necessary or desirable by the Landlord or the holder of
said lien in connection with said assignment. Any expense incurred in the
preparing, executing or recording of such assignment to any such holder shall
be without expense or cost to the Tenant. The Tenant further agrees, within ten
(10) days of Landlord's written request, to certify by written instrument duly
executed and acknowledged to any first mortgagee, first trust deed holder or
purchaser, or any proposed first mortgage lender, first trust deed holder or
purchaser, that this Lease is in full force and effect, or if not, in what
respect it is not, that this Lease has not been modified, or the extent to
which it has been modified, that there are no existing defaults hereunder to
the best of the knowledge of the party so certifying, or specifying the
defaults, if any, and any other information which Landlord shall reasonably
require. Any such certification shall be without prejudice as between the
Landlord and the Tenant, it being agreed that any document required hereunder
shall not be used in any litigation between the Landlord and the Tenant.
Landlord agrees to use its best efforts to obtain, on behalf of Tenant, a
non-disturbance, subordination and attornment agreement from the present
mortgagee; however, this Lease is not conditioned upon the same being granted,
and any charges assessed by the holders of such mortgages in connection with
the obtaining of the aforesaid non-disturbance agreement shall be paid by
Tenant.

Landlord agrees to obtain a non-disturbance agreement from the holder of any
future mortgage on the property, on behalf of Tenant and in connection
therewith, Tenant agrees to attorn to said mortgagee and any purchaser
following foreclosure. Any charges assessed by the holders of said mortgage in
connection with the obtaining of the aforesaid non-disturbance agreement shall
be paid by Tenant.

Notwithstanding anything contained herein to the contrary, in no event will
Tenant be required to pay more than Two Thousand and 00/100 ($2,000.00) Dollars
in the aggregate for any charges assessed by the holders of the aforesaid
mortgages in connection with obtaining the aforesaid non-disturbance
agreements.


                            ARTICLE XV

                        Defaults, Remedies

               Section 15.01. If, during the Term any one or more of the
following acts or occurrences (any one of such occurrences or acts being
hereinafter called an Event of Default) shall happen:

                    (A) The Tenant shall default in making any payment of Basic
Rent or any Additional Rent as and when the same shall become due and payable,
and such default shall continue for a period of ten (10) days after notice from
the Landlord that such payment is due and unpaid; or

                    (B) The Tenant shall default in the performance of or
compliance with any of the other covenants, agreements, terms or conditions of
this Lease to be performed by the Tenant (other than any default curable by
payment of money), and such default shall continue for a period of thirty (30)
days after written notice thereof from the Landlord to the Tenant, or, in the
case of a default which cannot with due diligence be cured within thirty (30)
days, the Tenant shall fail to proceed promptly (except for unavoidable delays)
after the giving of such notice and with all due diligence to cure such default
and thereafter to prosecute the curing hereof with all due diligence (it being
intended that as to a default not susceptible of being cured with due diligence
within thirty (30) days, the time within which such default may be cured shall
be extended for such period as may be reasonably necessary to permit the same
to be cured with all due diligence); or

                    (C) The Tenant or any guarantor of this Lease shall file a
voluntary petition in bankruptcy or shall be adjudicated a bankrupt or
insolvent, or shall file any petition or answer seeking any reorganization,
composition, readjustment or similar relief under any present or future
bankruptcy or other applicable law, or shall seek or consent to or acquiesce in
the appointment of any trustee, receiver, or liquidator of the Tenant or any
guarantor of this Lease or of all or any substantial part of its properties or
of all or any part of the Demised Premises; or

                    (D) If, within sixty (60) days after the filing of an
involuntary petition in bankruptcy against the Tenant or any guarantor of this
Lease, or the commencement of any proceeding against the Tenant or such
guarantor seeking any reorganization, composition, readjustment or similar
relief under any law, such proceeding shall not have been dismissed, or if,
within sixty (60) days after the appointment, without the consent or
acquiescence of the Tenant or such guarantor, of any trustee, receiver or
liquidator of the Tenant or such guarantor, or of all or any part of the
Demised Premises, such appointment shall not have been vacated or stayed on
appeal or otherwise, or if, within sixty (60) days after the expiration of any
such stay, such appointment shall have been vacated, or if, within sixty (60)
days after the taking possession, without the consent or acquiescence of the
Tenant or such guarantor, of the property of the Tenant, or of such guarantor
by any governmental office or agency pursuant to statutory authority for the
dissolution or liquidation of the Tenant or such guarantor, such taking shall
not have been vacated or stayed on appeal or otherwise; or

                    (E) If the Demised Premises shall be abandoned by the
Tenant for a period of thirty (30) consecutive days.

then, and in any such event, and during the continuance thereof, the Landlord
may, at its option, then or thereafter while any such Event of Default shall
continue and notwithstanding the fact that the Landlord may have any other
remedy hereunder or at law or in equity, by notice to the Tenant, designate a
date, not less than ten (10) days after the giving of such notice, on which
this Lease shall terminate; and thereupon, on such date the Term of this Lease
and the estate hereby granted shall expire and terminate upon the date
specified in such notice with the same force and effect as if the date
specified in such notice was the date hereinbefore fixed for the expiration of
the Term of this Lease, and all rights of the Tenant hereunder shall expire and
terminate, but the Tenant shall remain liable as hereinafter provided. The
parties agree that either party who brings an action to enforce any obligation
of the other party under this Lease shall, if successful, be entitled to
recover from said unsuccessful party all reasonable attorneys' fees and other
reasonable expenses incurred in enforcing said obligation against the
unsuccessful party, this to survive the expiration or sooner termination of
this Lease.

               Section 15.02. If this Lease is terminated as provided in
Section 15.01, or as permitted by law, the Tenant shall peaceably quit and
surrender the Demised Premises to the Landlord, and the Landlord may, without
further notice, enter upon, re-enter, possess and repossess the same by summary
proceedings, ejectment or other legal proceedings, and again have, repossess
and enjoy the same as if this Lease had not been made, and in any such event
neither the Tenant nor any person claiming through or under the Tenant by
virtue of any law or an order of any court shall be entitled to possession or
to remain in possession of the Demised Premises, and the Landlord, at its
option, shall forthwith, notwithstanding any other provision of this Lease, be
entitled to recover from the Tenant in lieu of all other claims for damages on
account of such termination as and for liquidated damages an amount equal to
the excess of all Term Basic Rent and Additional Rent reserved hereunder for
the unexpired portion of the Term of this Lease discounted at the rate of six
(6%) percent per annum to the then present worth, over the fair rental value of
the Demised Premises at the time of termination for such unexpired portion of
the Term (the rent received on a reletting shall be conclusively accepted as
the fair rental value). Nothing herein contained shall limit or prejudice the
right of the Landlord, in any bankruptcy or reorganization or insolvency
proceeding, to prove for and obtain as liquidated damages by reason of such
termination an amount equal to the maximum allowed by any bankruptcy or
reorganization or insolvency proceedings, or to prove for and obtain as
liquidated damages by reason of such termination, an amount equal to the
maximum allowed by any statute or rule of law whether such amount shall be
greater or less than the excess referred to above.

               Section 15.03. If the Landlord re-enters and obtains possession
of the Demised Premises, as provided in Section 15.02 of this Lease, following
an Event of Default, the Landlord shall have the right, without notice, to
repair or alter the Demised Premises in such a manner as the Landlord may deem
necessary or advisable so as to put the Demised Premises in good order and to
make the same rentable, and shall have the right, at the Landlord's option, to
relet the Demised Premises or a part thereof, and the Tenant shall pay to the
Landlord on demand all reasonable expenses incurred by the Landlord in
obtaining possession, and in altering, repairing and putting the Demised
Premises in good order and condition and in reletting the same, including
reasonable fees of attorneys and architects, and all other reasonable expenses
or commissions, and the Tenant shall pay to the Landlord upon the rent payment
dates following the date of such re-entry and including the date for the
expiration of the Term of this Lease in effect immediately prior to such
re-entry, the sums of money which would have been payable by the Tenant as
Monthly Basic Rent and Additional Rent hereunder on such rent payment dates if
the Landlord had not re-entered and resumed possession of the Demised Premises,
deducting only the net amount of rent (basic and additional), if any, which the
Landlord shall actually receive (after deducting from the gross receipts the
expenses, costs and payments of the Landlord which in accordance with the terms
of this Lease would have been borne by the Tenant) in the meantime from and by
any reletting of the Demised Premises, and the Tenant shall remain liable for
all sums otherwise payable by the Tenant under this Lease, including but not
limited to the expense of the Landlord aforesaid, as well as for any deficiency
aforesaid, and the Landlord shall have the right from time to time to begin and
maintain successive actions or other legal proceedings against the Tenant for
the recovery of such deficiency, expenses or damages or for a sum equal to any
Monthly Basic Rent payment and Additional Rent. As an alternative remedy, the
Landlord shall be entitled to damages against the Tenant for breach of this
Lease, at any time (whether or not the Landlord shall have become entitled to
or shall have received any damages as hereinabove provided) in an amount equal
to the excess, if any, of the Term Basic Rent and Additional Rent which would
be payable under this Lease at the date of the expiration of the Term, less the
amount of Term Basic Rent and Additional Rent received by the Landlord upon any
reletting, both discounted to present worth at the rate of six (6%) percent per
annum, semi-annually. The obligation and liability of the Tenant to pay the
Term Basic Rent and the Additional Rent shall survive the commencement,
prosecution and termination of any action to secure possession of the Demised
Premises. Nothing herein contained shall be deemed to require the Landlord to
wait to begin such action or other legal proceedings until the date when this
Lease would have expired had there not been an Event of Default.

               Section 15.04. The Tenant hereby waives all right of redemption
to which the Tenant or any person under it may be entitled by any law nor or
hereafter in force. Notwithstanding anything herein contained, Landlord agrees
to use reasonable efforts to relet the Demised Premises in order to mitigate
its damages, but nothing herein shall limit the Landlord's right, in its sole
discretion, to approve any tenant and to determine the terms and conditions of
any lease, including but not limited to rent and length of term. The Landlord's
remedies hereunder are in addition to any remedy allowed by law.

               Section 15.05. In the event of any breach or threatened breach
by Tenant of any of the agreements, terms, covenants or conditions contained in
this Lease, Landlord shall be entitled to enjoin such breach or threatened
breach and shall have the right to invoke any right or remedy allowed at law or
in equity or by statute or otherwise as though re-entry, summary dispossess
proceedings, and other remedies were not provided for in this Lease. During the
pendency of any proceedings brought by Landlord to recover possession by reason
of default, Tenant shall continue all money payments required to be made to
Landlord, and Landlord may accept such payments for use and occupancy of the
Demised Premises. In such event, Tenant waives its right in such proceedings to
claim as a defense that the receipt of such money payments by Landlord
constitutes a waiver by landlord of such default.


                            ARTICLE XVI

                      Assignment and Sublease

               Section 16.01. The Tenant may not mortgage, pledge, hypothecate,
assign, transfer, sublet or otherwise deal with this Lease or of the Demised
Premises in any manner except as specifically provided for in this Article XVI.

               Section 16.02. In the event that Tenant desires to sublease the
whole or any portion of the Demised Premiss or assign the within Lease to any
other party, Tenant shall give Landlord written notice of such desire and
furnish Landlord with an exact copy of the proposed assignment or sublease not
less than thirty (30) days prior to the effective date on which Tenant desires
to make such assignment or sublease and the identity of the subtenant or
assignee. The Tenant shall not submit, nor shall Landlord accept, any
assignment or sublease for review which has a proposed rent less than the
current market value. The Landlord shall require a Five Hundred and 00/100
($500.00) Dollar payment to cover its handling charges for each request for
consent to any sublet or assignment prior to its consideration of the same.

               Section 16.03. The Landlord shall have a period of thirty (30)
days following receipt of the aforementioned notice within which to notify the
Tenant in writing that Landlord elects either:

                    (A) to terminate this Lease as to the space so affected as
of the date so specified by the Tenant as above (with the same effect as if
such date was the date fixed herein for the expiration of the Term) in which
event Tenant will be relieved of all further obligation hereunder as to such
space; or

                    (B) to, upon the execution of the proposed sublease or
assignment to the proposed subtenant or assignee, assume the proposed
assignment or sublease so that such prospective sublessee or assignee shall
then become the tenant of the Landlord hereunder; or

                    (C) to permit the Tenant to assign or sublet such space,
subject, however, to the Tenant remaining liable for the observance of all of
the covenants and provisions of this Lease, including, but not limited to the
payment of Term Basic Rent reserved herein, through the entire Term of this
Lease. If the rental rate agreed between Tenant and assignee or sublessee is
greater than the Term Basic Rent and Additional Rent that Tenant must pay
Landlord (computed on the basis of an average square foot rent for the Demised
Premises), then all of such excess rental shall be shared equally by Landlord
and Tenant; or

                    (D) to reasonably refuse to consent to Tenant's assignment
or sublet and to continue this Lease in full force and effect. The Landlord's
refusal to consent shall not be deemed unreasonable if, by way of example and
not by way of limitation, the proposed assignment or sublet is to any
governmental or quasi-governmental agency or to anyone whose use would impose
abnormal or excessive wear and tear on the Demised Premises.

If Landlord should fail to notify Tenant in writing of such election within
said thirty (30) day period, Landlord shall be deemed to have elected option
(C) above. No future assignment or subletting shall be made except upon
compliance with this Section.  Any attempted assignment or sublease by Tenant
in violation of this Section shall be void. This absolute prohibition against
assigning or subletting except in compliance with this Section shall include
those by operation of law or statute.

               Section 16.04. In any event, except as otherwise provided in
Section 16.03, the acceptance by the Landlord of any Basic Rent or Additional
Rent from the assignee or from any of the subtenants or the failure of the
Tenant to insist upon a strict performance of any of the terms, conditions and
covenants herein shall not release the Tenant herein, nor any assignee assuming
this Lease, from any and all of the obligations herein during and for the
entire Term of this Lease.

               Section 16.05. Notwithstanding anything contained herein to the
contrary, any sublet or assignment to an Affiliated Company or to any entity
into which Tenant has been merged or which is wholly owned by Tenant, or by
which Tenant is wholly owned in connection with a joint venture entered into by
Tenant shall not be subject to the provisions of Sections 16.01, 16.02, and
16.03(A), (B) and (D). As used herein, Affiliated Company shall mean any
corporation related to such party as a parent, subsidiary or brother-sister
corporation so that such corporation and such party or such corporation and
such party and other corporations constitute a controlled group as determined
under Section 1563 of the Internal Revenue Code of 1986, as amended and as
elaborated by the Treasury Regulations promulgated thereunder.

In the event that any or all of Tenant's interest in the Demised Premises
and/or this Lease is transferred by operation of law to any trustee, receiver,
or other representative or agent of Tenant, or to Tenant as a debtor in
possession, and subsequently any and all of Tenant's interest in the Demised
Premises and/or this Lease is offered or to be offered by Tenant or any
trustee, receiver, or other representative or agent of Tenant as to its estate
or property (such person, firm or entity being hereinafter referred to as the
"Grantor"), for assignment, conveyance, lease, or other disposition to a
person, firm or entity other than Landlord (each such transaction being
hereinafter referred to as a "Disposition"), it is agreed that Landlord has and
shall have a right of first refusal to purchase, take, or otherwise acquire,
the same upon the same terms and conditions as the Grantor thereof shall accept
upon such Disposition to such other person, firm, or entity; and as to each
such Disposition the Grantor shall give written notice to Landlord in
reasonable detail of all of the terms and conditions of such Disposition within
twenty (20) days next following its determination to accept the same but prior
to accepting the same, and Grantor shall not make the Disposition until and
unless Landlord has failed or refused to accept such right of first refusal as
to the Disposition, as set forth herein.

Landlord shall have sixty (60) days next following its receipt of the written
notice as to such Disposition in which to exercise the option to acquire
Tenant's interest by such Disposition, and the exercise of the option by
Landlord shall be effected by notice to that effect sent to the Grantor; but
nothing herein shall require Landlord to accept a particular Disposition or any
Disposition, nor does the rejection of any one such offer of first refusal
constitute a waiver or release of the obligation of the Grantor to submit other
offers hereunder to Landlord. In the event Landlord accepts such offer of first
refusal, the transaction shall be consummated pursuant to the terms and
conditions of the Disposition described in the notice to Landlord. In the event
Landlord rejects such offer of first refusal, Grantor may consummate the
Disposition with such other person, firm, or entity; but any decrease in price
of more than two (2%) percent of the price sought from Landlord or any change
in the terms of payment for such Disposition shall constitute a new transaction
requiring a further option of first refusal to be given to Landlord hereunder.
Without limiting any of the provisions of Article XV, if pursuant to the
Federal Bankruptcy Code (herein the "Code"), or any similar law hereafter
enacted having the same general purpose, Landlord declines the right provided
it in the preceding paragraph and 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 one (1)
year's Annual Basic Rent and Additional Rent for the next succeeding twelve
(12) months (which Additional Rent shall be reasonably estimated by Landlord),
which deposit shall be held by Landlord for the balance of the Lease 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 same manner
specified for security in Section 23.02.

Except as specifically set forth above, no portion of the Demised Premises or
of Tenant's interest in this Lease may be acquired by any other person or
entity, whether by assignment, mortgage, sublease, transfer, operation of law
or act of the Tenant, nor shall Tenant pledge its interest in this Lease or in
any security deposit required hereunder.

               Section 16.06. If Tenant is a corporation and if at any time
during the Lease Term the persons owning a majority of its "voting stock" at
the time of the execution of this Lease should cease to own a majority of such
voting stock (except as the result of transfers by bequest or inheritance),
Tenant covenants to notify Landlord of any such transfer and such transfer
shall be deemed an assignment of this Lease. In the event of such transfer,
Landlord may either (a) not unreasonably withhold its consent thereto or (b)
terminate this Lease by notice to Tenant to be effective ninety (90) days after
service. This Section shall not apply whenever Tenant is a corporation, the
outstanding stock of which is listed on a recognized stock exchange. For the
purposes of this Section 16.06, stock ownership shall be determined in
accordance with the principles set forth in Section 544 of the Internal Revenue
Code of 1986, as amended, to and including the date of this Lease, and the term
"voting stock" shall refer to shares of stock regularly entitled to vote for
the election of directors of the corporation.

               Section 16.07. Tenant shall have no claim, and hereby waives the
right to any claim, against Landlord for money damages by reason of any
refusal, withholding or delaying by Landlord of any consent, and in such event,
Tenant's only remedies therefor shall be an action for specific performance,
injunction or declaratory judgment to enforce any such requirement. Landlord
acknowledges that Tenant may commence such action by means of an order to show
cause before the Superior Court of New Jersey, in which event Landlord
acknowledges Tenant's rights to an expedited proceeding and to notify Landlord
of the institution of the Order to Show Cause by telephone means. Landlord and
Tenant further agree that the determination of such Court shall be conclusive
and non-appealable.

                           ARTICLE XVIII

                           Holding Over

               Section 18.01. If the Tenant shall remain in the Demised
Premises after the expiration of the Term without having executed and delivered
a new lease with the Landlord, such holding over shall not constitute a renewal
or extension of this Lease. The Landlord may, at its option, elect to treat the
Tenant as one who has not removed at the end of its Term, and thereupon be
entitled to all the remedies against the Tenant provided by law in that
situation, or the Landlord may elect, at its option, to construe such holding
over as a tenancy from month to month, subject to all the terms and conditions
of this Lease, except as to duration thereof, and in that event the Tenant
shall pay Monthly Basic Rent and Additional Rent in advance in the amount as
provided for pursuant to N.J.S.A. 2A:42-6. The time limitations described in
this Article XVIII shall not be subject to extension for Force Majeure, except
that any increased rental as herein described shall not be applicable for the
first thirty (30) days beyond the expiration of the Term if, and only if, said
holding over is as a result of Tenant's inability to move its furniture,
fixtures and equipment to a new location for reasons attributable to Force
Majeure.


                            ARTICLE XIX

                               Liens

               Section 19.01. Tenant shall not do any act, or make any
contract, which may create or be the foundation for any lien or other
encumbrance upon any interest of Landlord or any ground or underlying lessor in
any portion of the Demised Premises. If, because of any act or omission (or
alleged act or omission) of Tenant, any Notice of Intention, mechanic's or
other lien, ,charge, or order for the payment of money or other encumbrance
shall be filed against Landlord and/or any ground or underlying lessor and/or
any portion of the Demised Premises (whether or not such lien, charge, order,
or encumbrance is valid or enforceable as such), Tenant shall, at its own cost
and expense, cause same to be discharged of record or bonded within fifteen
(15) days after the filing thereof; and Tenant shall indemnify and save
harmless Landlord and all ground and underlying lessor(s) against and from all
costs, liabilities, suits, penalties, claims, and demands, including reasonable
counsel fees, resulting therefrom. If Tenant fails to comply with the foregoing
provisions, Landlord shall have the option of discharging or bonding any such
lien, charge, order, or encumbrance, and Tenant agrees to reimburse Landlord
for all costs, expenses and other sums of money in connection therewith (as
additional rental) with interest at the maximum rate permitted by law promptly
upon demand. All materialmen, contractors, artisans, mechanics, laborers and
any other person now or hereafter contracting with Tenant or any contractor or
subcontractor of Tenant for the furnishing of any labor services, materials,
supplies, or equipment with respect to any portion of the Demised Premises, at
any time from the date hereof until the end of the Lease Term, are hereby
charged with notice that they look exclusively to Tenant to obtain payment for
same.

             Condition of Demised Premises, Loss, Etc.

occurring in or about the Demised Premises, for any reason whatsoever, to
include but not be limited to: any existing or future condition, defect, matter
or thing in the Demised Premises; the acts, omissions or negligence of other
persons or tenants in and about the Demised Premises; theft or burglary from
the Demised Premises; the negligence of Landlord, its agents, servants or
invitees; and defects, errors or omissions in the construction or design of the
Demised Premises and/or the Building including the structural and
non-structural portions thereof. Tenant covenants and agrees to make no claims
for any such loss, damage or injury at any time. Nothing in this Section 20.01
shall be construed to preclude any claim for personal injury by any third party
or for any property damage claim by any third party for its property, provided
said property is not under the care, custody or control of Tenant if such loss
or injury is due in whole or in part to Landlord's negligence or misconduct or
that of its employees or agents. As used herein, third parties include but are
not limited to employees, agents, contractors, invitees or any other party not
occupying the Demised Premises pursuant to a sublet or license or as a
successor or assign of Tenant.


                            ARTICLE XXI

to enter the Demised Premises at reasonable hours to examine the same, or to
exhibit the Demised Premises to prospective purchasers and to place upon the
Demised Premises a suitable "For Sale" sign, which sign must be approved by the
Tenant, which approval shall not be unreasonably withheld. For twelve (12)
months prior to the expiration of the Term, the Landlord, or its agents, may
exhibit the Demised Premises to prospective tenants and may place the usual "To
Let" signs thereon. Notwithstanding the foregoing, except in the event of an
emergency, Landlord shall provide Tenant with reasonable telephone notice prior
to entering the Demised premises in connection with this Section 21.01.


                           ARTICLE XXII

                               Signs

               Section 22.01. No sign, advertisement or notice shall be affixed
to or placed upon any part of the Demised Premises by the Tenant, except in
such manner, and of such size, design and color as shall be approved in advance
in writing by the Landlord, which approval the Landlord shall not unreasonably
withhold, provided: (i) that Tenant comply with all applicable governmental
ordinances and regulations and receives all necessary governmental approvals
required for erection and maintenance of the sign and (ii) no later than the
last day of the Term, Tenant shall, at Tenant's expense, remove the sign and
repair all injury done by or in connection with the installation or removal of
the sign. Notwithstanding the foregoing, Landlord hereby consents to that sign
to be located at the Demised Premises which is described on Exhibit D attached

event Landlord may require the Tenant to deposit security in the amount
specified in Section 16.05 to adequately assure Tenant's performance of all of
its obligations under this Lease, including all payments subsequently accruing.
Failure of Tenant to deposit the security required by this Section within
thirty (30) days after Landlord's written demand shall constitute a material
breach of this Lease by Tenant.

               Section 23.04. Anything in this Lease to the contrary
notwithstanding, at Landlord's option, Tenant shall pay a "Late Charge" of
eight (8%) percent of any installment of Monthly Basic Rent or Additional Rent

The Tenant agrees to indemnify and hold Landlord harmless from any and all
claims of Pyne, Gordon and any other brokers with whom Tenant has dealt in
connection with this Lease, and expenses in connection therewith arising out of
or in connection with the negotiation of or the entering into this Lease by
Landlord and Tenant. Landlord represents and warrants to the Tenant that LPC,
Pyne and Gordon are the sole brokers with whom it has dealt in connection with
this Lease and Landlord shall indemnify and hold harmless Tenant from any and
all claims arising out of conduct which is inconsistent with said
representation. Landlord shall pay any commission owing to LPC in connection
with this Lease.

claim it might otherwise have in and waives its right of distraint of, the
machinery, fixtures and other property of the Tenant, and in any other property
of any nature whether on or off the Demised Premises, belonging to the Tenant.
The provisions of this Section are intended to apply to the Landlord's common

                       ERISA Representation

               Section 29.01. Tenant represents and warrants to Landlord to the

affiliate of Tenant has employee pension or profit-sharing plans that hold, in
the aggregate, beneficial interests representing greater than five (5%) percent

that a breach of the foregoing representation and warranty may constitute a
prohibited transaction under the terms of the Employee Retirement Income
Security Act of 1974 and the Internal Revenue Code, as modified by PTE 82-51,
an administrative exemption from certain of the prohibited transaction rules
granted to the Innovest, N.V. by the United States Department of Labor [46 Fed.
Reg. 14, 238 (April 2, 1982)].   If at any time Tenant or any affiliate of
Tenant has employee pension or profit-sharing plans that hold, in the
aggregate, beneficial interests representing greater than five (5%) percent of
the total assets of any Innovest, N.V. investment fund, Tenant shall promptly
advise Landlord of such fact in writing.


                            ARTICLE XXX

                           Miscellaneous

               Section 30.01. Partial Invalidity. If any term or provision of
this Lease or the application thereof to any party or circumstances shall to
any extent be invalid or unenforceable, the remainder of this Lease or the
application of such term or provision to parties or circumstances other than
those to which it is held invalid or unenforceable, shall not be affected
thereby, and each term and provision of this Lease shall be valid and enforced
to the fullest extent permitted by law.  Section 30.02. Waivers. One or more
waiverS by either party of the obligation of the other to perform any covenant
or condition shall not be construed as a waiver of a subsequent breach of the
same or any other covenant or condition.

The receipt of Basic Rent or Additional Rent by the Landlord, with knowledge of
any breach of this Lease by the Tenant or of any default on the part of the
Tenant in the observance or performance of any of the conditions or Covenants
of this Lease, shall not be deemed to be a waiver of any provision of this
Lease except with respect to the non-payment of Basic Rent or Additional Rent
and then only to the extent of the Basic Rent or Additional Rent actually
received by Landlord. Neither acceptance of the keys nor any other act or thing
done by the Landlord or any agent or employee during the Term herein demised
shall be deemed to be in acceptance of a surrender of said Demised Premises,
excepting only an agreement in writing signed by the Landlord accepting or
agreeing to accept such a surrender.

documents executed by the parties in connection herewith contain the entire and
only agreement between the parties and no oral statements or representations or
prior written matter not contained in this instrument or in any other documents
executed by the parties in connection herewith shall have any force or effect.
This Lease shall not be modified in any way or terminated except by a writing
executed by both parties.

               Section 30.07. Landlord. The term "Landlord" as used in this

obligations of the Landlord hereunder accruing after such transfer, and it
shall be deemed without further agreement between the parties that such
grantee, transferee or assignee has assumed and agreed to observe and perform
all obligations of the Landlord hereunder arising during the period it is the
holder of the Landlord's interest hereunder.

               Section 30.08. Words of Duty. Whenever in this Lease any words
of obligation or duty are used, such words or expressions shall have the same

               Section 30.09. Cumulative Remedies. The specified remedies to
which the Landlord or the Tenant may resort under the terms of this Lease are
cumulative and are not intended to be exclusive of any other remedies or means
of redress to which the Landlord or the Tenant may lawfully be entitled in case
of any breach or threatened breach of any provision of this Lease.

               Section 30.10. No option. The submission of this Lease Agreement
for examination does not constitute a reservation of, or option for, the
Demised Premises, and this Lease Agreement becomes effective as a Lease
Agreement only upon execution and delivery thereof by Landlord and Tenant.

               Section 30.11. Accord and Satisfaction. No payment by Tenant or
receipt by Landlord of a lesser amount that the Basic Rent and additional
charges payable hereunder shall be deemed to be other than a payment on account
of the earliest stipulated Monthly Basic Rent and Additional Rent, nor shall
any endorsement or statement on any check or any letter accompanying any check
or payment for Basic Rent or Additional Rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice
to Landlord's right to recover the balance of such Basic Rent and Additional
Rent or pursue any other remedy provided herein or by law.

               Section 30.12. Corporate Authority. If Tenant is a corporation,
Tenant represents and warrants that this Lease and the undersigned's execution
of this Lease has been duly authorized and approved by the corporation's Board
of Directors. The undersigned officers and representatives of the corporation
executing this Lease on behalf of the corporation represent and warrant that
they are officers of the corporation with authority to execute this Lease on

include those situations beyond either party's control, including by way of
example and not by way of limitation, acts of God; accidents; repairs; strikes;
shortages of labor, supplies or materials; inclement weather; or, where

proceeds. Any time limits required to be met by either party hereunder, whether
specifically made subject to Force Majeure or not, except those related to the
payment of Term Basic Rent or Additional Rent and except as to the time periods
set forth in Article XVIII, shall, unless specifically stated to the contrary
elsewhere in this Lease, be automatically extended by the number of days by
which any performance called for is delayed due to Force Majeure.

               Section 30.15. Additional Rent. As used in this Lease,
Additional Rent shall mean all sums in addition to Basic Rent payable by Tenant
to Landlord pursuant to the provisions of this Lease.
