     C.1.  If Lessor shall purchase any item of capital equipment or make any
capital expenditure intended to result in savings or reductions in the Common
Area Maintenance Charges and which Lessor reasonably believes shall provide
Lessee with the benefit of a savings or reduction in such Common Area
Maintenance Charges based upon the advice of Lessor's consultants, then the
actual costs for same shall be included in the Common Area Maintenance Charges,
to the extent hereinafter set forth.  Lessor shall deliver to Lessee, promptly
following Lessee's request, a copy of any concluded studies conducted by Lessor
which show anticipated savings or reductions in such Common Area Maintenance
Charges as a result of any planned capital expenditure or purchase of capital
equipment.  The costs of capital equipment or capital expenditures shall be
included in the Common Area Maintenance Charges in the year in which the costs
are incurred and in any subsequent years, on a straight-line basis, to the
extent that such items are amortized over such period of time as reasonably can
be estimated at the time in which such savings or reductions in such Common Area
Maintenance Charges are expected to equal Lessor's costs for such capital
equipment or capital expenditure, with an interest factor equal to two percent
(2%) above the interest rate payable on United States Treasury securities having
a maturity comparable to the period of amortization at the time Lessor incurred
said costs.  If Lessor shall lease any such item of capital equipment designed
to result in savings or reductions in any Common Area Maintenance Charges, then
the rentals and other costs paid pursuant to such leasing shall be included in
such Common Area Maintenance Charges for the year in which they were incurred.

     2. If Lessor shall purchase any item of capital equipment or make any other
capital expenditure in order to comply with Legal Requirements, Insurance
Requirements or Environmental Laws (as those terms are hereinafter defined) or
reasonably necessary in order to benefit or increase the safety and security of
the Building, Property, or its tenants and/or invitees, then the costs for same
shall be included in Common Area Maintenance Charges for the year in which the
costs are incurred and subsequent years, on a straight-line basis, amortized
over the useful life of such items, with an interest factor equal to two percent
(2%) above the interest rate payable on United States Treasury securities having
a maturity comparable to the useful life of such items at the time Lessor
incurred said costs.  If Lessor shall lease any such item of capital equipment
to comply with Legal Requirements, Insurance Requirements, Environmental Laws or
to increase safety and security then, in such event, the rentals and other costs
paid pursuant to such leasing shall be included in Common Area Maintenance
Charges for the year in which they were incurred.

     3. If during all or part of any year, including calendar year 1998, (i)
less than ninety-five percent (95%) of the leasable space in the Building is
occupied by tenants or occupants or (ii) Lessor shall furnish any particular
item(s) of work or service (which would constitute a Common Area Maintenance
Charge hereunder) to less than ninety-five percent (95%) of the leasable
portions of the Building or to only a portion of the Property, due to the fact
that less than ninety-five percent (95%) of the leasable portions of the
Building are occupied, or because such item of work or service is not required
or desired by the tenant of such portion, or such tenant is itself obtaining and
providing such item of work or service, or for other reasons, then, for the
purposes

                                     Page 4 of 40
<PAGE>
of computing the Additional Rent payable hereunder, the amount of Common Area
Maintenance Charges or the amount of the expenses attributable to such item as
the case may be, for such period shall be deemed to be increased by an amount
equal to the additional costs and expenses which would reasonably have been
incurred during such period had the Building been at least ninety-five percent
(95%) occupied or had Lessor furnished such item of work or services to such
other portions of the Building or the Property.

     D. Lessor shall have the absolute right, at all times during the Term and
any Renewal Term (as hereinafter defined) to increase, reduce, alter or
otherwise modify the way in which it uses, operates, repairs, or maintains the
Building and/or the Property and the cost thereof.  Nothing contained herein
shall require Lessor to incur or provide any particular service or charge in
connection with its use, operation, repair or maintenance of the Building and/or
Property, it being agreed and understood that the items described in Section
3.0l.B. are by way of illustration only and shall not obligate Lessor thereto,
except that Lessor shall maintain the Building and Property as a first class
office building located in Westchester County, New York.

     E. The term "Taxes" shall mean all such taxes, assessments, use and
occupancy taxes in respect of this Lease and any subleases made hereunder, water
and sewer charges, rates and rents, water and other meter charges and all such
other charges, taxes, levies and sums of every kind or nature whatsoever,
general and special, extraordinary as well as ordinary, whether or not now
within the contemplation of the parties, as shall or may during or in respect of
the Term (or any period prior to the Term for which Fixed Rent is payable) be
assessed, levied, charged or imposed upon or become a lien on the Property,
Building, or Demised Premises, or any part thereof, or anything appurtenant
thereto, or the sidewalks, streets or roadways in front of, adjacent to or
appurtenant to the Property, Building or Demised Premises (and which have a
basis related in any way to the Property, Building, or Demised Premises and/or
the use or manner of use thereof), or which, if imposed on Lessee or in respect
of the Property, Building or Demised Premises and if not paid by Lessee, would
be collectible from Lessor, or which have been so assessed, levied, charged or
imposed prior to the Term (but, in the last-mentioned case, only with respect to
a period falling within the Term); PROVIDED, HOWEVER, that, except if and to the
extent otherwise provided in the succeeding sentence, "Taxes" shall not mean
federal, state or local income taxes, franchise, excise, gift, transfer, capital
stock, estate, succession or inheritance taxes or penalties or interest for late
payment of any tax in respect of which Lessee shall have duly made payment of
Additional Rent as herein provided.  If, at any time during the Term, the
methods of taxation prevailing at the commencement of the Term shall be altered
so that, in lieu of or as a substitution in whole or in part for the taxes,
assessments, levies, impositions or charges now or hereafter levied, assessed or
imposed on real estate and the improvements thereon, shall be levied, assessed
or imposed any tax or other charge on or in respect of the Property, Building
and/or Demised Premises or the rents, income or gross receipts of Lessor
therefrom (including any county, town, municipal, state or federal levy), then
such tax or charge shall be deemed a Tax, but only to the extent that such Tax
would be payable if the Property, Building or Demised Premises, or the rent,
income or gross receipts received therefrom, were the only property of Lessor
subject to such Tax, and Lessee shall pay and discharge the same as herein
provided in respect of the payment of Taxes.

     F. The term "School Tax Base" shall mean the amount of Taxes as hereinabove
defined, imposed, levied, assessed and/or collected on the Property, for the
1997/1998 School Tax and "Town Tax Base" shall mean the amount of Taxes as
hereinabove defined, imposed, levied, assessed and/or collected on the Property
for the 1998 Town, County and State Tax.

     G. The term "School Tax Year" shall mean each period of twelve (12)
consecutive months commencing as of the first day of January of each such
period; and "Town Tax Year" shall mean each period of twelve (12) consecutive
months commencing as of the first day of January of each such period, in which
any part of the term of this Lease shall occur, or such other periods of twelve
(12) months as may be adopted as the fiscal year for real estate tax purposes.

     SECTION 3.02.A. Lessee shall pay to Lessor, as Additional Rent, during or
in respect of the period from the Commencement Date to the Expiration Date (both
dates inclusive) for each School Tax Year and Town Tax Year or portion thereof,
its proportionate share ("Lessee's Proportionate Share," as hereinafter defined)
of increases in Taxes which will be imposed, levied, assessed or collected on
the Property, and/or Building of which the Demised Premises are a part, for such
School Tax Year and/or Town Tax Year, as the case may be, over the respective
tax bases regardless of whether such increase results from a higher tax rate
and/or an increase in the assessed valuation of either the Property or Building
or any other tax.  Reasonable fees and expenses, if any, incurred in obtaining
any reduction in assessed valuation from the tentative
                                     Page 5 of 40
<PAGE>

assessment to the final assessment shall also be considered an increase in Taxes
for the purpose of this provision.  Such payments shall be made by Lessee as
Additional Rent in equal monthly installments during the applicable tax year
together with the payment of Fixed Rent.  Copies of tax bills applicable to the
School Tax Base and the Town Tax Base, as the case may be, and to any such
applicable tax year shall be made available by Lessor for inspection by Lessee
during normal business hours.  In the event of any reduction in Taxes after
final assessment and with respect to which Lessee has paid its proportionate
share, any such reduction, less fees and expenses incurred to obtain such
reduction shall be refunded in proportionate amounts to Lessee.

     B. If Lessor obtains a reduction of either the School Tax Base or Town Tax
Base by final determination of legal proceedings or otherwise, then: (i) the
School Tax Base or Town Tax Base shall be correspondingly revised, (ii) all Tax
payments theretofore paid or payable hereunder shall be recomputed on the basis
of such reduction, (iii) Lessee shall pay to Lessor as Additional Rent, within
thirty (30) days after receipt of a bill therefor, any deficiency between the
amount of such Tax payments theretofore computed and the amount thereof due as a
result of such recomputations and (iv) all future Tax payments shall be computed
using the revised School Tax Base and Town Tax Base.

     SECTION 3.03.A. Lessee shall pay to Lessor, as Additional Rent, during or
in respect of the period from the Commencement Date to the Expiration Date (both
dates inclusive) for each calendar year or portion thereof, Lessee's
Proportionate Share of the increases in the Common Area Maintenance Charges over
the over the Base Common Area Maintenance Charges (as hereinafter defined).
Such payments shall be made by Lessee as Additional Rent in equal monthly
installments during the applicable calendar year together with the payment of
Fixed Rent.

     B. The term "Base Common Area Maintenance Charges" shall mean the Common
Area Maintenance Charges in effect for the calendar year ending December 31,
1998.

     SECTION 3.04.A. At any time hereafter and from time to time, Lessor may
furnish to Lessee a Lessor's Statement setting forth (i) Lessor's actual Common
Area Maintenance Charges (or any one or more items thereof) and/or actual Taxes
for a period which shall have expired and/or (ii) Lessor's reasonable estimate
of Common Area Maintenance Charges and/or Taxes for a succeeding period.  Within
thirty (30) days next following rendition of each such Lessor's Statement,
Lessee shall pay to Lessor the entire amount, if any, shown on such Lessor's
Statement as being due with respect to any period which shall have expired.  In
addition, Lessee shall pay to Lessor, on the first day of each month following
rendition of each such Lessor's Statement, on account of the estimated
Additional Rent thereafter payable, a proportionate sum of the total Additional
Rent shown upon such Lessor's Statement as being Lessor's reasonable estimate
for a succeeding period on an annual basis (it being agreed that Lessor's
estimate shall in any event be deemed reasonable if it is based on actual Common
Area Maintenance Charges (or any one or more items thereto and/or actual Taxes
for a period which shall have expired immediately prior thereto, so that one
month prior to the end of such period, Lessee's Proportionate Share of the
increase shall be paid in full, and Lessee shall continue to pay Additional Rent
on such basis until receipt of a subsequent Lessor's Statement.  Such Additional
Rent shall be due and payable at the same time as each monthly installment of
Fixed Rent.

     B. A reconciliation shall be made upon each Lessor's Statement as follows:
Lessee shall be debited with any Common Area Maintenance Charges and/or Taxes
payable as shown on such Lessor's Statement, and credited with the aggregate of
the total amount, if any, paid by Lessee in accordance with the provisions of
the preceding paragraph on account of the estimated Additional Rent, for the
period or item in question, and, within thirty (30) days next following
rendition of such Lessor's Statement, Lessee shall pay Lessor the amount of any
net debit balance shown thereon or Lessor shall apply against the next ensuing
installments of Fixed Rent the net credit balance shown thereon.

     C. Without limiting the preceding provisions of Section 3.04, it is
understood that Lessor shall furnish a Lessor's Statement, for each calendar
year falling wholly or partially within the Term.

     SECTION 3.05.A. Lessor's failure to render Lessor's Statements with respect
to any period shall not prejudice Lessor's fight to render a Lessor's Statement
with respect to that or any subsequent period.  The obligations of Lessor and
Lessee under the provisions of this Article with respect to Additional Rent
shall survive the expiration or any sooner termination of the Term.

     B. Each Lessor's Statement shall be conclusive and binding upon Lessee
unless within thirty (30) days after receipt of such Lessor's Statement, Lessee
shall notify Lessor that it disputes

                                     Page 6 of 40
<PAGE>
the reasonableness or correctness of Lessor's Statement, specifying the respects
in which Lessor's Statement is claimed to be unreasonable or incorrect. Pending
the determination of such dispute by agreement or otherwise, Lessee shall pay
Additional Rent in accordance with the applicable Lessor's Statement, and such
payment will be without prejudice to Lessee's position.  If the dispute shall be
finally determined in Lessee's favor by a court of competent jurisdiction,
Lessor shall forthwith pay Lessee the amount of Lessee's overpayment of
Additional Rent resulting from compliance with Lessor's Statement.  Lessor, upon
request of Lessee, shall either make available to Lessee such documentation as
may be in Lessor's possession to support a particular Common Area Maintenance
Charge or permit Lessee to examine relevant portions of Lessor's books and
records.

     SECTION 3.06. Lessee shall pay and discharge, or cause to be paid and
discharged, the following items, regardless of to whom or how incurred, all
taxes and assessments, if any, which shall or may during the Term be charged,
levied, assessed or imposed upon, or become a lien upon, the personal property
of Lessee used in the operation of the Demised Premises and which if not paid by
Lessee, would be collectible from Lessor.

                         ARTICLE 4 - USE OF DEMISED PREMISES

title thereto and, subject to Lessor's obligations under Section 8.01, Lessee
accepts the Demised Premises in their "AS IS" state and condition on the

expressly set forth herein), express or implied, in fact or by law, by Lessor,

                                     Page 8 of 40
<PAGE>

and without recourse to Lessor, as to title thereto, the nature, condition or
usability thereof or as to the use or occupancy which may be made thereof.

     SECTION 5.02. If delivery of possession to the Demised Premises to Lessee
is delayed by reason of Unavoidable Delays (as hereinafter defined), then this
Lease and the validity thereof shall not be affected thereby and Lessee shall
not be entitled to terminate this Lease, to claim actual or constructive
eviction, partial or total, or to be compensated for loss or injury suffered as
a result thereof, nor shall the same be construed in any way to extend the Term,
PROVIDED, HOWEVER, that, notwithstanding the provisions of Article 1, the
Commencement Date shall be deemed to occur only if and when possession of the
Demised Premises is made available to Lessee.

     SECTION 5.03. The provisions of this Article shall be considered an express
provision to the contrary pursuant to New York REAL PROPERTY LAW Section 223-(a)
governing delivery of possession of the Demised Premises and any law providing
for such a contingency in the absence of such express agreement now or hereafter
enacted shall have no application in such case to the extent inconsistent with
this Lease.

                        ARTICLE 6 - UTILITIES, CLEANING, ETC.

     SECTION 6.01.A. During the Term hereof and any Renewal Term, Lessor shall
furnish to Lessee, during Normal Working Hours as hereinafter defined: (a)
necessary elevator facilities; (b) heat to the Demised Premises when reasonably
necessary or otherwise required by law in accordance with the specifications
provided for in this Lease; (c) water for ordinary lavatory and drinking
purposes, but if Lessee uses or consumes water for any other purposes or in
unusual and excessive quantities in Lessor's reasonable judgment, Lessor may
install a water meter at Lessee's expense in good working order and repair to
register such water consumption and Lessee shall pay for water consumed in
excess of ordinary lavatory and drinking purposes as shown on said meter as
Additional Rent as and when bills are rendered; (d) air conditioning and/or
cooling; (e) ventilation; and (f) electricity for Building lighting and normal
Building equipment and other incidental equipment ("Utility Service").

     B. The air conditioning and/or cooling system shall be designed to be
capable of maintaining inside conditions of not more than 78 degrees F when
outside conditions are not more than 89 degrees F dry bulb and 74 degrees F wet
bulb and a temperature of 70 degrees F when the outside temperature is 11
degrees F.  The design capabilities of the system are based upon and limited to
the following conditions: (i) the occupancy does not exceed one (1) person for
each 150 square feet of area; (ii) the total connected electrical load does not
exceed 5 watts per square foot of installed ceiling area for all purposes,
including lighting and power; and (iii) proper use of window blinds to control
sunload.  The system shall provide fresh air as per code requirements.  If due
to use of the Demised Premises in a number exceeding the aforementioned
occupancy and electrical load criteria, or due to rearrangement of partitioning
after the initial preparation of the Demised Premises, interference with normal
operation of the air conditioning in the Demised Premises results, necessitating
changes in the air conditioning system servicing the Demised Premises, such
changes shall be made by Lessor upon written notice to Lessee and at Lessee's
sole cost and expense.  Lessee agrees to keep all windows closed, and to lower
and close window coverings when necessary because of the sun's position whenever
the said air conditioning system is in operation, and Lessee agrees at all times
to cooperate fully with Lessor and to abide by all the regulations and
requirements which Lessor may prescribe for the proper functioning and
protection of the said air conditioning system.  Lessor, throughout the Term,
shall have free and unrestricted access to any and all air conditioning
facilities in the Demised Premises.

     C. Except as otherwise specifically provided for in this Lease, Lessor
represents that Lessee shall have access (by elevator) to the Demised Premises
Twenty-Four (24) hours a day, Seven (7) days a week.

     D. Lessor agrees that Lessee shall have the right to use the existing
supplemental air conditioning units located in the Demised Premises, which shall
be in working order on the Commencement Date.  During the Term hereof and any
Renewal Term, Lessor shall furnish to Lessee condenser water ("Condenser Water")
serving not more than Five (5) tons of rated cooling capacity for use in
connection with the Supplemental Units serving the Demised Premises.  Lessee
agrees to pay Lessor for all Condenser Water used in connection with the
Supplemental Units at the rate of One Hundred and Twenty-Five and 00/100
($125.00) Dollars per month, per rated ton of connected load (the "Condenser
Water Charge"), PROVIDED, HOWEVER, that in no

                                     Page 9 of 40
<PAGE>

event shall Lessor ever be obligated to provide Lessee with more than Five (5)
tons per hour of Condenser Water for use in connection with the Supplemental
Units.

     SECTION 6.02. During the Term hereof and any Renewal Term, Lessor shall
furnish to Lessee cleaning services for the Demised Premises in accordance with
the Cleaning Specifications annexed hereto as EXHIBIT "D."

     SECTION 6.03.A. If Lessee uses the Demised Premises outside Normal Working
Hours, Lessee agrees to pay to Lessor an overtime charge to cover Lessor's
actual expenses for electricity for lighting and normal Building Equipment (as
hereinafter defined) and other incidental equipment, extra building maintenance,
building employee overtime, furnishing water for lavatories, air cooling, heat,
ventilation, wear and tear, etc. caused by Lessee's overtime use ("Overtime
Services").

     B.1. Lessor shall furnish such Overtime Services to Lessee as may be
required provided that (i) Lessee pays to Lessor as Additional Rent special
overtime charges (the "Overtime Charges") therefor, which is presently at the
rate of One Hundred and Seventy-Five and 00/100 ($175.00) Dollars per hour,
along with Lessee's next monthly installment of Fixed Rent if such service shall
have been finished to Lessee prior to the fifteenth (15th) day of the month or
along with the subsequent monthly installment of Fixed Rent if such service
shall have been furnished to Lessee after the fifteenth (15th) day of the month,
(ii) that Lessee's request shall be received by Lessor by not later than 2:00
P.M. on the day for which such required after hours service is requested (and by
not later than 2:00 P.M. on the day preceding any requested before-hours
service), (iii) that Lessor shall not be required to furnish such Overtime
Services to Lessee for more than twenty (20) hours in any one (1) week, and (iv)
the Building HVAC system is not then producing chilled water for future HVAC
use.  Notwithstanding anything contained to the contrary in this Article 6,
Lessee shall not be required to pay Overtime Charges for intermittent use of the
Demised Premises outside Normal Working Hours, provided that such use shall not
be on a scale and of a frequency so as to constitute the regular operation of
Lessee's business outside Normal Working Hours.  In no event, however, shall
Lessor be obligated to supply heating or air conditioning outside of Normal
Working Hours unless Lessee shall request and pay for the same as provided in
this Article 6.

     2. Lessee agrees that the Overtime Charges and Condenser Water Charge may,
from time to time, be increased by Lessor, with not less than thirty (30) days
prior written notice to Lessee, if the rates at which Lessor purchases
electrical energy from the public utility corporation supplying electrical
current to the Building of which the Demised Premises are a part or shall be
increased, or the cost of supplying Condenser Water shall be increased, or any
tax is imposed upon Lessor's receipt from the sale or resale of electrical
energy or Condenser Water by any Federal, State or Municipal Authority, or any
charges incurred or taxes payable by Lessor in connection therewith shall be
increased.  The Overtime Charges and Condenser Water Charge shall be increased
by an amount equal to the product of the respective hourly rate times the
percentage increase in the rates at which Lessor purchases electrical energy
from the public utility corporation as aforesaid, or the percentage increase in
the cost of producing Condenser Water, as the case may be.

     SECTION 6.04.A. Lessee acknowledges and agrees that Lessor shall furnish
electrical current to Lessee for lighting, electrical appliances and/or office
equipment in the Demised Premises, including electrical current for the
Supplemental Units ("Electric Service") based on the method of including the use
thereof within the Fixed Rent and, accordingly, Lessee agrees that the Fixed
Rent provided for in Article 2 of this Lease has been increased to compensate
Lessor for supplying Electric Service on the basis of Two and 25/100 dollars
($2.25) per square foot per annum for each square foot contained in the Demised
Premises (hereinafter referred to as the "Base Charge") payable in equal monthly
installments commencing on the Commencement Date.  By the execution of this
Lease, Lessee acknowledges and agrees that the Base Charge shall not be
contestable by Lessee at a future date and shall only be increased by Lessor at
a future date in accordance with this Section.  Lessor will furnish electricity
to Lessee through presently installed electrical facilities, which Lessor
represents to be at least five (5) watts of connected load per square foot of
installed ceiling area for all lighting and power purposes, for Lessee's
reasonable use.

     B.1. Lessee shall make no substantial alterations or additions to the
initial lighting, electrical appliances or office equipment without first
obtaining written consent from Lessor (which consent shall not be unreasonably
withheld or delayed) in each instance.  Lessor warrants that the electrical
facilities servicing the Demised Premises is in good working order and can
accommodate a normal office installation with associated office machinery and
equipment.

                                    Page 10 of 40
<PAGE>

Lessee agrees that at all times its use of Electric Service shall not exceed the
capacity or overload any of the central and appurtenant installations for
Electric Service including, but not limited to all wires, feeders, risers,
electrical boxes, switches, outlets, connections, and cables located in the
Property, Building, or Demised Premises or any other mechanical equipment spaces
located therein.  Lessee's use of Electric Service shall not interfere with the
use thereof by other occupants of the Property, or Building and shall be of such
a nature, as determined by Lessor in its reasonable judgment and discretion, so
as not cause permanent damage or injury to the Demised Premises or the Building
of which the Demised Premises are a part, or cause or create a dangerous or
hazardous condition or entail excessive or unreasonable alterations, repairs or
expense, or interfere with or disturb other tenants or occupants.

     2. If at any time prior to or during the Term or any Renewal Term of this
Lease, subject to the restrictions contained elsewhere in this Lease: (i) Lessee
installs substantial additional or substituted lighting, electrical appliances,
office equipment or otherwise increases its use of Electric Service in excess of
five (5) watts of connected load per square foot of installed ceiling area for
all purposes, and/or; (ii) subject to the provisions of Article 8 of this Lease,
electrical feeders, risers, wiring or other electrical facilities serving the
Demised Premises shall be installed by Lessor, Lessee or others, on behalf of
Lessee or any person claiming through or under Lessee in addition to the
feeders, risers, wiring or other electrical facilities necessary to serve the
lighting fixtures, electrical appliances, office equipment and electrical
receptacles initially located in the Demised Premises; then the Fixed Rent shall
be increased by an amount determined by the electrical engineer selected by
Lessor who shall certify the amount of the Additional Rent to be increased in
writing to Lessor and Lessee.  Following any such determination and
certification by the electrical engineer, this Lease shall automatically be
modified by increasing the Additional Rent by an amount equal to (i) the product
of the Base Charge times the percentage increase in Lessee's use of electrical
current over that for Lessee's initially installed lighting, electrical
appliances and office equipment and/or (ii) the product of the Base Charge times
the percentage increase in the potential additional electrical energy made
available to Lessee annually based upon the estimated capacity of such
additional electrical feeders, risers, wiring or other electrical facilities, as
the case may be.  As evidence of such modification, such electrical engineer's
certification shall be delivered by Lessor to Lessee and also appended hereto.
Any such increase shall be effective as of the date of the first use by Lessee
of such additional service and retroactive to such date if necessary.  In
addition, Lessee shall pay to Lessor, as Additional Rent, within ten (10) days
of the date of a notice therefor from Lessor, the total actual Cost (as
hereinafter defined) to Lessor of the additional electrical feeders, risers,
wiring, or other electrical facilities serving the Demised Premises.

     C. If, at any time or times after the date of this Lease, the rates at
which Lessor purchases electrical energy from the public utility corporation
supplying electrical current to the Building of which the Demised Premises are a
part shall be increased, or any tax is imposed upon Lessor's receipt from the
sale or resale of electrical energy or gas or telephone service to Lessee by any
Federal, State or Municipal Authority, or any charges incurred or taxes payable
by Lessor in connection therewith shall be increased, the Additional Rent shall
be increased by an amount equal to the product of the Base Charge times the
percentage increase in the rates at which Lessor purchases electrical energy
from the public utility corporation as aforesaid, over those rates in effect on
the date of the calculation of the Base Charge.  Following any such rate
increase or other charge, this Lease shall automatically be modified by
increasing the Additional Rent for the remainder of the term hereof in
accordance with this Subsection and, as evidence of such modification,
documentation of such rate increase or other charge shall be delivered by Lessor
to Lessee and also appended hereto.  Any such increase in the Additional Rent
shall be effective as of the date of any such increase in cost or other charge
to Lessor and shall be retroactive to such date if necessary.

     D. Notwithstanding anything contained to the contrary in this Article 6,
Lessor shall have the right, at its option, to conduct a survey of the Demised
Premises by an electrical engineer of Lessor's choosing at any time during the
term of this Lease in order to determine Lessee's actual use of electrical
current therein.  In the event that Lessor's survey provided for in the
preceding sentence shall indicate that Lessee's use of electrical current
exceeds five (5) watts of connected load per square foot of installed ceiling
area for all purposes, Lessee, upon receipt of notice from Lessor, shall pay to
Lessor an increase in Fixed Rent equal to an amount determined by multiplying
the Base Charge times the percentage increase in Lessee's use of electrical
current over five (5) watts of connected load per square foot of installed
ceiling area for all purposes.  Any such increase shall be payable in accordance
with the terms of this Article 6 and shall be effective as of the date of
Lessee's first increased use of electrical current and shall be retroactive to
such date, if necessary.

     SECTION 6.05. Except as otherwise specifically provided for in this Lease,
Lessor reserves the right to temporarily stop, interrupt and/or suspend Utility
Service, and/or Electric Service when necessary by reason of accident or for
repairs, alterations, replacements or improvements necessary or desirable in the
judgement of Lessor for as long as may be reasonably required by reason thereof.
The repairs, alterations, replacements or improvements shall be done with a
minimum of inconvenience to Lessee and Lessor shall pursue same with due
diligence.

     SECTION 6.06. Except to the extent caused by the negligent or wilful acts
or on omissions of Lessor, its employees, agents or contractors, Lessor shall in
no way be liable for any loss, damage, or expense which Lessee may incur as a
result of the change, at any time, of the character or quality of Electric
Service, or Utility Service or any failure of or defect in Electric Service, or
Utility Service by reason of any public or private utility company then
supplying such service to the Property, Building or the Demised Premises and
Lessee agrees to hold the Lessor harmless and to indemnify it from and against
any loss, liability or damage in connection therewith.  This indemnity shall
survive the expiration or other termination of this Lease.

                          ARTICLE 7 - REPAIR AND MAINTENANCE

     SECTION 7.01.A. Subject to the provisions of Section 7.02 hereof, Lessee
shall, during the Term of this Lease and any Renewal Term, at Lessee's sole cost
and expense, take good care of, maintain and make all repairs (other than
structural) in the Demised Premises, and the fixtures and equipment therein and
appurtenances thereto, including but not limited to, the Supplemental Units,
internal doors and entrances, door checks, internal signs, floor covering,
interior walls, columns and partitions; and lighting, heating, hot water,
plumbing and sewerage facilities, sprinkler system and sprinkler heads located
within the Demised Premises and serve only the Demised Premises.

     B. If Lessee refuses or neglects to maintain or make repairs or otherwise
fails to perform any of Lessee's repair or maintenance obligations hereunder,
Lessor shall have the right, but shall not be obligated, to make such repairs or
perform on behalf of and for the account of Lessee.  All sums so paid by Lessor
in connection with the payment or performance by it or any of the obligations of
Lessee hereunder and all actual and reasonable costs, expenses and disbursements
paid in connection therewith or enforcing or endeavoring to enforce any right
under or in connection with this Lease, or pursuant to law, together with
interest thereon at the minimum legal rate from the respective dates of the
making of such payment, shall constitute Additional Rent payable by Lessee under
this Lease and shall be paid by Lessee to Lessor upon demand by Lessor.  The
provisions of this Section shall survive the expiration or other termination of
this Lease.

     SECTION 7.02.A. Lessor shall not be required to make any repairs or
improvements of any kind upon the Demised Premises except for necessary
structural repairs to the Building or for damage caused by a casualty or
Lessor's negligent or wilful acts or omissions, excluding Lessee's property.
Lessor shall during the Term of this Lease and any Renewal Term, maintain and
repair all common areas and other facilities in or about the Property and/or the
Building, exclusive of doors, door frames, door checks, windows and window
frames.  Lessor shall have the right to construct, maintain and operate lighting
and other facilities on all said areas and improvements; to police the same; to
change the area, level, location and arrangement of parking areas and other
facilities; to build multistory parking facilities; to restrict parking by
Lessees, their officers, directors, agents and employees, to enforce parking
charges (by operation of meters and otherwise to the extent required by law);
and to close all or any portion of said areas or facilities to such extent as
may be legally sufficient to prevent a dedication thereof or the accrual of any
right to any person or the public therein; to close temporarily all or any
portion of the parking areas or facilities to discourage non-visitor parking.
Lessor shall operate and maintain the common areas in such manner as Lessor in
its discretion shall determine, and Lessor shall have full right and authority
to employ and discharge all personnel with respect thereto.  If Lessor shall
designate an employee or lessee parking area or areas, Lessee and its employees
shall use only such areas for parking and Lessee shall cooperate fully with
Lessor in enforcing this covenant.

     B. In the event that Lessor is unable or fails to provide Critical Services
(as hereinafter defined) which it is obligated to provide under this Lease
solely as a result of Lessor's negligence, wilful acts or omissions, and the
loss of such services causes all or part of the Demised Premises to become
unusable or access to the Demised Premises is not reasonably available for more
than five (5) consecutive business days, or if such condition is caused by any
other reason other than as provided for herein and such condition continues for
thirty (30)
                                    Page 12 of 40
<PAGE>

consecutive days, and the Demised Premises are in fact not used for the purposes
for which they were leased, during such period, then in such event, Lessee shall
be entitled to a pro rata abatement of Rent commencing with the sixth (6th)
consecutive business day, or the thirty-first (31st) consecutive day that same
are unusable, as the case may be; PROVIDED, HOWEVER, that Lessee shall not be
entitled to any abatement of Rent if such unusability is (a) caused by the
negligence or wilful act or omission of Lessee or any of Lessee's servants,
employees, agents, or licensees; or (b) where such condition arises in
connection with work performed by Lessor at the request of Lessee to make a
decoration, alteration, improvement or addition; or (c) where the repair in
question are those which Lessee is obligated to make or furnish under any of the
provisions of this Lease.  The provisions of this paragraph B shall not apply in
the event of a condition caused by fire or other casualty or condemnation as
provided for in Articles 12 and 18, respectively.  As used herein, the term
"Critical Services" shall mean: (i) electricity; (ii) heating through the
Buildings heating system but excluding supplemental heating systems installed by
Lessee; (iii) ventilating and air conditioning through the Building's AC System
but excluding any supplemental units; (iv) water (including condenser water);
and/or (v) elevator service to the Demised Premises.

     SECTION 7.03. "Repairs" as used herein shall mean all repairs,
replacements, renewals, alterations, additions and betterments.  All contracts
between Lessee and others for installations, maintenance, and repairs and
alterations involving the Demised Premises, including maintenance agreements,
shall be subject to the prior written approval of Lessor, not to be unreasonably
withheld or delayed.

     SECTION 7.04. Lessor shall not be required to make any repairs or
replacements to the common areas occasioned by the act or negligence of Lessee,
its agents, employees, invitees, customers, licensees, or contractors, except to
the extent that Lessor is reimbursed therefor under any policy of insurance
permitting waiver of liability and containing a waiver of subrogation, except as
otherwise provided in this Article and Article 12 of this Lease.

                      ARTICLE 8 - THE WORK; LESSEE'S ALTERATIONS

     SECTION 8.01. Lessor shall have no obligation whatsoever to perform any
build-out or similar work to Demised Premises, and Lessee agrees to accept same
in "AS IS" physical order and condition on the Commencement Date and without any
representation or warranty, express or implied, in fact or by law, by Lessor,
and without recourse to Lessor, as to title thereto, the nature, condition or
usability thereof or as to the use or occupancy which may be made thereof.
Notwithstanding the foregoing, Lessor agrees to perform the work set forth on
the plans and specifications annexed hereto as EXHIBIT "E" and made a part
hereof (the "Work").  Lessor agrees to perform, at its sole cost and expense,
that portion of the Work more particularly set forth on EXHIBIT "F" annexed
hereto and made a part hereof as Lessor's financial contribution to the Work.
Lessee agrees to pay Lessor for the Cost (as that term is hereinafter defined)
of that portion of the Work set forth on EXHIBIT "F" as Lessee's financial
contribution to the Work ("Lessee's Financial Contribution").  Lessee shall pay
to Lessor as Additional Rent, Lessee Financial Contribution within ten (10)
business after demand therefor.

     SECTION 8.02. Following the Commencement Date, Lessee may complete its own
build-out, if any, and fully equip the Demised Premises with all trade and
operating fixtures and equipment, plumbing, lighting and other fixtures and
equipment, furniture, furnishings, floor covering, and any and all other items
necessary for the proper operation of Lessee's business ("Lessee's Work").  All
equipment permanently affixed to the Demised Premises by Lessee shall not be
subject to liens, conditional sales contracts, security agreements or chattel
mortgages.  Nothing contained herein shall prohibit Lessee from purchasing
display and other moveable equipment which may be subject to liens, conditional
sales contracts, security agreements or chattel mortgages ("Lessee's Trade
Fixtures").  Lessee shall complete or cause to be completed all of Lessee's Work
required on Lessee's part to be performed in and at the Demised Premises under
this Lease pursuant to Lessor's STANDARD REQUIREMENTS FOR ALTERATIONS TO BE
PERFORMED BY LESSEES' annexed hereto as EXHIBIT "G," as may be amended from time
to time.

     SECTION 8.03. Other than as specifically provided for in Section 8.02
hereof, Lessee shall not do any construction, work or alterations to the Demised
Premises, nor shall Lessee install any items other than Lessee's Trade Fixtures
without first: (1) obtaining Lessor's written consent, which consent shall not
be unreasonably withheld or delayed AND (2) complying with all of the terms,
covenants and conditions contained in Lessor's STANDARD REQUIREMENTS FOR
ALTERATIONS TO BE PERFORMED BY LESSEES'.

<PAGE>
                           ARTICLE 9 - COMPLIANCE WITH LAWS

     SECTION 9.01. Lessor represents that the Demised Premises, the Building and
Property and all of Lessor's Work will comply with all Legal Requirements,
Environmental Laws and Insurance Requirements as of the Commencement Date.

     SECTION 9.02. Throughout the Term of this Lease and all Renewal Terms, if
any, Lessee shall promptly comply with all Legal Requirements, Environmental
Laws and Insurance Requirements whether or not such compliance involves
structural repairs or changes or be required on account of any particular use to
which the Demised Premises, or any part, may be put, and whether or not any such
Legal Requirements, Environmental Laws, or Insurance Requirements be of a kind
not now within the contemplation of the parties hereto.  Compliance by Lessee
with Legal Requirements, Environmental Laws, and Insurance Requirements shall be
at Lessee's sole cost and expense.  Lessee shall not contest the application or
validity of any such Legal Requirements, Environmental Laws, or Insurance
Requirements without the prior written consent of Lessor in each such instance.
Any repair or change required under this Section shall be deemed a repair for
the purposes of Article 7.  With respect to actions necessary to comply with
Legal Requirements, Insurance Requirements and Environmental Laws which, due to
their nature, can only be taken by Lessor, Lessor, at Lessee's expense, will
cooperate with Lessee in facilitating such compliance.


                        ARTICLE 10 - RIGHTS RESERVED TO LESSOR

     SECTION 10.01. Lessee shall permit Lessor, Lessor's's agents, and its
invitees to enter the Demised Premises, or any part thereof, at all reasonable
times and upon reasonable notice to Lessee provided same does not unreasonably
interfere with Lessee's business for the purposes of (a) inspecting the same,
(b) curing Events of Default of Lessee (after ten (10) days' notice to Lessee,
except that no notice shall be required in case of an emergency), (c) showing
the same to mortgagees, appraisers, or prospective lenders, purchasers or
lessees (Lessor shall only show the Demised Premises to prospective lessees in
the last nine (9) months of the Term, as may be extended), (d) observing the
performance by Lessee of its obligations under this Lease, (e) performing any
act or thing which Lessor may be obligated or have the right to do under this
Lease or otherwise, and (f) any other reasonable purpose.  Lessor and any
providers of Utility Services or other services shall have the right to maintain
existing utility, mechanical, electrical and other systems and to enter upon the
Demised Premises to make such repairs and alterations therein or in or to the
Demised Premises as may, in the reasonable opinion of Lessor, be deemed
necessary or advisable.  Lessor shall not be liable for inconvenience,
annoyance, disturbance or loss of business to Lessee or any sublessee by reason
of making any repairs or the performance of any work, or on account of bringing
materials, tools, supplies and equipment into or through the Demised Premises
during the course thereof and the obligations of Lessee under this Lease shall
not be affected thereby.  The rights provided in this Article shall be exercised
so as to minimize interference with the use and occupancy of the Demised
Premises by Lessee.  Nothing contained in this Article shall impose, or shall be
construed to impose on Lessor any obligation to maintain the systems referred to
in this Article or the Demised Premises or anything appurtenant thereto, or to
make repairs or alterations thereof or thereto, or to create any liability for
any failure to do so.

     SECTION 10.02.A. Without abatement or diminution in rent, Lessor reserves
and shall have the following additional rights: (a) to change the street address
and/or the name of the Building of which the Demised Premises are a part and/or
the Property and/or the locations of entrances, passageways, doors, doorways,
corridors, elevators, stairs, toilets, or other public parts of the Building
and/or Property without liability to Lessee, PROVIDED, HOWEVER, that Lessor
shall take no action which adversely affects Lessee's access to and/or use of
the Demised Premises and/or Building, (b) to approve in (in Lessor's reasonable
judgment) writing all sources furnishing construction work, painting,
decorating, repairing, maintenance and any other work in or about the Demised
Premises, (c) to erect, use and maintain pipes and conduits in and through the
Demised Premises, provided that any such pipes, and conduits are located behind
the walls and in the ceiling of the Demised and do not materially reduce the
usable square footage of the Demised Premises and do not unreasonably interfere
with the operation of Lessee's existing systems and facilities servicing the
Demised Premises; (d) to charge to Lessee any reasonable and actual expense
including overtime cost incurred by Lessor in the event that repairs,
alterations, decorating or other work in the Demised Premises are made or done
after ordinary business hours at Lessee's request, (e) to immediately enter and
alter, renovate, and redecorate the Demised Premises (without reduction or
abatement of rent or incurring any liability to Lessee for compensation), if
during the last six (6) months of the Term or of any Renewal Term Lessee shall
                                    Page 14 of 40
<PAGE>

have removed all of Lessee's property therefrom, and (f) grant to anyone the
exclusive right to conduct any particular business or undertaking in the
Building of which the Demised Premises are a part.

     B. Lessor may exercise any or all of the foregoing rights hereby reserved
to Lessor without being deemed guilty of an eviction, actual or constructive, or
disturbance or interruption of Lessee's use or possession and without being
liable in any manner toward Lessee and without limitation or abatement of Rent
or other compensation, and such acts shall have no effect on this Lease.

                                ARTICLE 11 - INSURANCE

     SECTION 11.01.A. Lessee shall obtain and keep in full force and effect
during the Term, and during any earlier period of time when Lessee or Lessee's
agents, employees, or contractors may enter the Demised Premises at its own cost
and expense:

          (1) commercial general liability insurance (with a contractual
     liability endorsement covering the matters set forth in Article 16) having
     a combined single limit of not less than Two Million ($2,000,000.00)
     Dollars (including umbrella coverage) protecting Lessor, any Lessor's agent
     which is acting as a property manager for the Property, the holder of any
     Mortgage, or Lessor under any Superior Lease and Lessee as insureds, as
     their interests appear (and naming each such person as an insured party or
     as an additional insured, as their interests appear) against any and all
     claims for bodily injury, death or property damage occurring, during the
     Term and during any earlier period of time when Lessee or Lessee's agents,
     employees, or contractors may enter the Demised Premises;

          (2) insurance (herein sometimes referred to as "Lessee's fire
     (casualty) insurance") against loss or damage by any and all risks and
     hazards to Lessee's Property (as hereinafter defined) for the full
     replacement value thereof (including coverages which are currently
     sometimes referred to as "all risk" with coverage written on a replacement
     cost basis);

          (3) workers' compensation and employees liability insurance in
     accordance with the laws of the State of New York and all Governmental
     Authorities having jurisdiction over the Demised Premises and/or the
     Property; and

          (4) Lessee shall insure and keep insured in the name of Lessee, with
     the name of Lessor included as an additional insured, as its interests may
     appear, at Lessee's expense (i) all internal plate glass in the Demised
     Premises; (ii) if there is a steam boiler, steam generator, or any other
     combustible device, mechanism or appliance in, on, adjoining or beneath the
     Demised Premises, for the exclusive use of the Lessee, Lessee shall insure
     and keep the same insured with a broad form boiler insurance in the amount
     of at least Five Hundred Thousand ($500,000.00) Dollars.  Lessee shall
     further insure, at Lessor's request, against any other peril generally
     insured against by a business of Lessee's type.

     B. Said insurance is to be written in form and substance reasonably
satisfactory to Lessor by an insurance company, licensed to do business in the
State of New York, which shall be rated by Best's Insurance Rating Service with
at least a rating equal to A:XII.  Lessee shall procure, maintain and place such
insurance and pay all premiums and charges therefor and upon failure to do so
Lessor may, but shall not be obligated to, procure, maintain and place such
insurance or make such payments, and in such event Lessee agrees to pay the
amount thereof plus interest at the maximum legal rate, to Lessor on demand as
Additional Rent.  If Lessee has other locations that it owns or leases, said
policy shall include an aggregate per location endorsement.  Lessee shall cause
to be included in all such insurance policies (i) a provision to the effect that
the same will not be canceled or modified except upon not less than thirty (30)
days' prior written notice to the Lessor, and (ii) a provision to the effect
that the naming of any person other than Lessee as an insured shall not obligate
such person to pay any premium.  Each such Lessee's fire (casualty) insurance
policy shall contain an agreement by the insurer that the act or omission of one
insured will not invalidate the policy as to any other insured.  Not less than
ten (10) days prior to the Commencement Date the original insurance policies or
appropriate certificates and paid receipts therefor (together with a photocopy
of the policy, if Lessor shall so request), shall be deposited with Lessor.  Any
renewals or endorsements thereto shall also be deposited with Lessor, not less
than ten (10) days prior to the expiration date of the policy being renewed,

                                    Page 15 of 40
<PAGE>
replaced or endorsed, to the end that said insurance shall be in full force and
effect at all times during the Term.

     SECTION 11.02. Lessee agrees to use reasonable efforts to include in each
of its insurance policies (insuring the Demised Premises and Lessor's property
therein, against loss occasioned by fire or other casualty) a waiver of the
insurer's right of subrogation against the Lessor, or if such waiver should be
unobtainable or unenforceable, (a) an express agreement that such policy shall
not be invalidated if the insured waives or has waived before the casualty the
right of recovery against any party responsible for a casualty covered by the
policy, or (b) any other form of permission for the release of the other party,
or (c) the inclusion of the Lessor as an additional insured, as its interests
may appear.  Lessee, upon request from Lessor from time to time, will furnish
evidence of the nature of the insurance arrangements made concerning the subject
matter of this Section.

     SECTION 11.03. As long as both parties' fire (casualty) insurance policies
then in force include the waiver of subrogation or agreement or permission to
release liability referred to in Section 11.02 or name the other party as an
additional insured, each party hereby waives (and agrees to cause any other
permitted occupants of the Demised Premises to execute and deliver to the other
party written instruments waiving) any right of recovery against the other
party, the holder of the Mortgage, or Superior Lease, and any servants,
employees, agents or contractors of the other party, or of any such Lessor's or
holder, or of any such other tenants or occupants, for any loss occasioned by
fire or other casualty, that is an insured risk under Lessee's fire (casualty)
insurance policies.  In the event that at any time either party's fire
(casualty) insurance carriers shall not include such or similar provisions in
the other party's fire (casualty) insurance policies, the waivers set forth in
the foregoing sentence shall be deemed of no further force and effect.  During
any period when either party fails to maintain such fire (casualty) insurance,
for the purposes of the first sentence of this Section there shall be deemed to
be in effect such fire (casualty) insurance meeting the requirements of such
sentence.

     SECTION 11.04. Nothing contained in this Lease shall (i) relieve Lessee of
any liability to Lessor or to its insurance carriers which Lessee may have under
law or the provisions of this Lease in connection with any damage to the Demised
Premises by fire or other casualty; (ii) impose upon Lessor any duty to procure
or maintain any kinds of insurance or any particular amounts or limits of any
such kinds of insurance.

     SECTION 11.05. Lessor shall insure the Building with all risk insurance
coverage in such amounts so as to avoid co-insurance and Lessor agrees that such
policies shall contain a waiver of subrogation in favor of Lessee.

                          ARTICLE 12 - DAMAGE OR DESTRUCTION

     SECTION 12.01. If the Demised Premises or any part thereof shall be damaged
by fire or other casualty, Lessee shall give prompt notice thereof to Lessor and
Lessor shall proceed (subject to the provisions of this Article) with reasonable
diligence to repair or cause to be repaired such damage.  Except as provided in
Section 12.05, the Fixed Rent shall be abated proportionately to the extent that
the Demised Premises shall have been rendered Untenantable (as hereinafter
defined), such abatement to be from the date of such damage or destruction to
the date the Demised Premises shall no longer be Untenantable.

     SECTION 12.02. If the Demised Premises shall be totally damaged or the
whole of the Demised Premises shall be rendered Untenantable by fire or other
casualty, and Lessor has not terminated this Lease pursuant to Section 12.03 and
Lessor has not completed the making of the required repairs and restored and
rebuilt the Demised Premises and/or access thereto within one (1) year from the
date of such damage or destruction to the level of demising walls only, and such
additional time after such date, as shall equal the aggregate period Lessor may
have been delayed in doing so by Unavoidable Delays or adjustment of insurance,
Lessee may serve notice on Lessor of its intention to terminate this Lease and
if within thirty (30) days thereafter, Lessor shall not have substantially
completed the making of the required repairs and restored and rebuilt the
Demised Premises to the level of demising walls, then in such events, this Lease
shall terminate on the expiration of such thirty (30) day period as if such
termination date were the Expiration Date, and the Fixed Rent and Additional
Rent shall be apportioned as of such date of sooner termination and any prepaid
portion of Fixed Rent and Additional Rent for any period after such date shall
be refunded by Lessor to Lessee.

     SECTION 12.03.A. If the Demised Premises shall be totally damaged or the
whole of the Demised Premises shall be rendered Untenantable by fire or other
casualty or if the Demised
                                    Page 16 of 40
<PAGE>

Premises shall be so damaged by fire or other casualty that substantial
alteration or reconstruction shall, in Lessor's reasonable opinion, be required,
then and in such events Lessor may, at its option, terminate this Lease and the
Term and estate hereby granted by giving Lessee not less than thirty (30) days,
nor more than sixty (60) days, notice of such termination, within ninety (90)
days after the date of such damage.  In the event that such notice of
termination shall be given, this Lease and the Term and estate hereby granted
shall terminate as of the date provided in such notice of termination (whether
or not the Term shall have commenced) with the same effect as if that were the
Expiration Date, and the Fixed Rent and Additional Rent shall be apportioned as
of such date of sooner termination, mid any prepaid portion of Fixed Rent and
Additional Rent for any period after such date shall be refunded by Lessor to
Lessee.

     B. If the Demised Premises shall be totally damaged or the whole or
substantially all of the Demised Premises shall be rendered untenantable by fire
or other casualty, and Lessor has not terminated this Lease as provided in
Section 12.03.A., Lessor shall notify Lessee, within ninety (90) days after such
fire or other casualty, as to the estimated period of time necessary to complete
the required repairs and restore and rebuild the Demised Premises to the level
of demising walls.  If such Lessor's estimate exceeds one (1) year, from the
date of such notice, or if Lessor falls to deliver such notice, then in such
events, Lessee may serve on Lessor, within thirty (30) days of its receipt of
Lessor's notice, or the expiration of the ninety (90) days after such fire or
other casualty, as the case may be (time being of the essence with respect
thereto), notice of its intention to terminate this Lease on a date which shall
be not more than thirty (30) days from the date of Lessee's notice.  If Lessee
gives notice of its intention to cancel this Lease as provided herein, then in
such event, this Lease shall terminate on the expiration of such thirty (30) day
period as if such termination date were the Expiration Date, and the Fixed Rent
and Additional Rent shall be apportioned as of such date of sooner termination
and any prepaid portion of Fixed Rent and Additional Rent for any period after
such date shall be refunded by Lessor to Lessee.  Lessee's failure to notify
Lessor within the thirty (30) day period shall be deemed a waiver of the right
to terminate this Lease.

     SECTION 12.04. Lessor shall not be liable for any inconvenience or
annoyance to Lessee or injury to the business of Lessee resulting in any way
from such damage by fire or other casualty or the repair thereof.

     SECTION 12.05. Lessee shall restore all improvements made by Lessee to the
Demised Premises, at Lessee's sole cost and expense.  Nothing herein contained
shall relieve Lessee from any liability to the Lessor or to its insurers in
connection with any damage to the Property, Building or Demised Premises by fire
or other casualty if Lessee shall be legally liable in such respect.
Notwithstanding any of the foregoing provisions of this Article, if by reason of
some action or inaction on the part of Lessee or any of its employees, agents,
officers, directors or contractors, Lessor or the holder of the Mortgage or
Superior Lease shall be unable to collect all of the insurance proceeds
(including rent insurance proceeds) applicable to damage or destruction of the
Demised Premises by fire or other cause, then, without prejudice to any other
remedy which may be available against Lessee, the abatement of Fixed Rent
provided for in this Article shall not be effective to the extent of the
uncollected insurance proceeds.

     SECTION 12.06. This Lease shall be considered an express agreement to the
contrary pursuant to New York REAL PROPERTY LAW Section 227 governing any case
of damage to or destruction of the Demised Premises or any part thereof by fire
or other casualty, and any law providing for such a contingency in the absence
of such express agreement, now or hereafter enacted, shall have no application
in such case to the extent inconsistent with this Lease.

     SECTION 12.07. Lessee shall, at its own cost and expense, remove all of
Lessee's property from the Demised Premises as Lessor shall require in order to
repair and restore the Demised Premises and Lessor shall not be obligated to
commence repairs or restoration of the Demised Premises until such property has
been removed by Lessee from the damaged portion of the Demised Premises.  Should
Lessee neglect, fail, or refuse to remove its aforesaid property within thirty
(30) days after such damage or destruction, the provisions for abatement of
Fixed Rent contained herein shall be suspended and of no force and effect
whatsoever until Lessee has completed such removal.  In no event shall the
Lessor be required to repair or replace Lessee's merchandise, trade fixtures,
furniture, furnishings, inventory and equipment.

                   ARTICLE 13 - CURING DEFAULT'S; FEES AND EXPENSES

     SECTION 13.01. If Lessee shall default in the full and prompt performance
of any covenant contained herein and to be performed on Lessee's part, Lessor,
after notice to Lessee in accordance with provisions of this Lease (except that
a lesser notice appropriate to the

                                    Page 17 of 40
<PAGE>

circumstances shall be required in case of an emergency), without being under
any obligation to do so and without thereby waiving such default may perform
such covenant for the account and at the expense of Lessee and may enter upon
the Demised Premises for any such purpose and take all action thereon as may be
necessary therefor.  All reasonable sums so paid by Lessor in connection with
the payment or performance by it of any of the obligations of Lessee hereunder
and all actual and reasonable costs, expenses and disbursements paid in
connection therewith or enforcing or endeavoring to enforce any right under or
in connection with this Lease, or pursuant to law, together with interest
thereon at the maximum legal rate from the respective dates of the making of
each such payment, shall constitute Additional Rent payable by Lessee under this
Lease and shall be paid by Lessee to Lessor upon demand by Lessor.  The
provisions of this Section shall survive the expiration or other termination of
this Lease.

                           ARTICLE 14 - DEFAULT PROVISIONS

     SECTION 14.01.A. If any one or more of the following events shall happen
and shall not have been cured within any applicable grace period herein
provided:

          (1) if default shall be made in the due and punctual payment of Fixed
     Rent or Additional Rent payable by Lessee under this Lease when and as the
     same shall become due and payable, and such default shall continue for a
     period of five (5) days after written notice thereof from Lessor to Lessee
     (provided that no such notice shall be required if, during the period of
     one (1) year immediately preceding the date of default, there shall have
     been two (2) or more defaults in the due and punctual payment of Fixed Rent
     or Additional Rent payable by Lessee under this Lease when and as the same
     shall have been due and payable); or

          (2) if default shall be made by Lessee in performance of, or
     compliance with, any of the covenants, agreements or conditions contained
     in this Lease and either (i) in the case of a default or a contingency
     which can with due diligence be cured within thirty (30) days, such default
     shall continue for a period of thirty (30) days after written notice
     thereof from Lessor to Lessee, or (ii) in the case of a default or a
     contingency which cannot with due diligence be cured within thirty (30)
     days, Lessee shall fail, after written notice thereof from Lessor, to
     proceed promptly and with all due diligence to commence to cure the same
     and thereafter to prosecute the curing of such default with all due
     diligence (it being intended that, in connection with a default which is
     not susceptible of being cured with due diligence within thirty (30) days
     the time of Lessee within which to cure the same shall be extended for such
     period as may be necessary for the curing thereof with all due diligence);
     or

          (3) if Lessee shall file a voluntary petition seeking an order or
     relief under Title 11 of the United States Code or similar law of any
     jurisdiction applicable to Lessee, or Lessee shall be adjudicated a debtor,
     bankrupt or insolvent, or shall file any petition or answer seeking,
     consenting to or acquiescing in any order for relief, reorganization,
     arrangement, composition, adjustment, winding-up, liquidation, dissolution
     or similar relief with respect to Lessee or its debts under the present or
     any future bankruptcy act or any other present or future applicable
     federal, state or other statute or law, or shall file an answer admitting
     or failing to deny the material allegations of a petition against it for
     any such relief or shall generally not, or shall be unable to, pay its
     debts as they become due or shall admit in writing in any filing with any
     court or Governmental Authority its insolvency or its inability to pay its
     debts as they become due, or shall make a general assignment for the
     benefit of creditors or shall seek or consent or acquiesce in the
     appointment of any trustee, receiver, examiner, assignee, sequestrator,
     custodian or liquidator or similar official of Lessee or of all or any part
     of Lessee's property or if Lessee shall take any action in furtherance of
     or authorizing any of the foregoing; or if Lessee shall call a meeting of,
     or propose any form of arrangement, composition, extension or adjustment
     with its creditors holding a majority in amount of Lessee's outstanding
     indebtedness; or

          (4) if any case, proceeding or other action shall be commenced or
     instituted against Lessee, seeking to adjudicate lessee a bankrupt or
     insolvent, or seeking an order for relief against Lessee as debtor, or
     reorganization, arrangement, composition, adjustment, winding-up,
     liquidation, dissolution or similar relief with respect to Lessee or its
     debts under the present or any future bankruptcy act or any other present
     or future applicable federal, state or other statute or law, or seeking
     appointment of any trustee, receiver, examiner, assignee, sequestrator,
     custodian or liquidator or similar official of Lessee or of all or part of
     Lessee's property, which either (i) results in the entry of an

                                    Page 18 of 40
<PAGE>

     order for relief, adjudication of bankruptcy or insolvency or such an
     appointment or the issuance or entry of any other order having similar
     effect or (ii) remains undismissed for a period of ninety (90) days; or if
     any case, proceeding or other action shall be commenced or instituted
     against Lessee seeking issuance of a warrant of execution, attachment,
     restraint or similar process against Lessee or any of Lessee's property
     which results in the taking or occupancy of the Demised Premises or an
     attempt to take or occupy the Demised Premises which shall not have been
     vacated, discharged, or stayed or bonded pending appeal within ninety (90)
     days after the entry thereof; or

          (5) if any event shall occur or any contingency shall arise whereby
     this Lease or the estate hereby granted to the unexpired balance of the
     Term would, by operation of law or otherwise, devolve upon or pass to any
     person other than Lessee, except as is expressly permitted under Article
     27, or if default shall be made by Lessee in the performance of, or
     compliance with the covenants, agreements and conditions set forth in
     Article 27; or

          (6) if Lessee's (other than Lessee herein named) obligations under
     this Lease shall have been guaranteed by any person other than Lessee and
     such person shall default in observance or performance of any term,
     covenant or condition to be observed or performed by such person under the
     instrument or agreement containing such guarantee; or

          (7) if any financial statement or other information furnished to
     Lessor by Lessee in connection with this Lease is materially false or
     misleading; or

          (8) if Lessee shall default in the observance or performance of any
     term, covenant or condition on Lessee's part to be observed or performed
     under the provisions of Section 35.09; or

          (9) if Lessee is the subject of a Chapter 11 reorganization under the
     Bankruptcy Reform Act of 1978 and such reorganization is not confirmed
     within eighteen (18) months from the time of filing of a voluntary or
     involuntary petition thereunder (it being understood that in such event
     Lessee consents to the termination of the automatic stay provisions of
     Section 362 of such Act);

 then and in any such event (hereinafter sometimes called an "Event of Default")
Lessor may give written notice ("Termination Notice") to Lessee specifying such
Event of Default or Events of Default and stating that this Lease and the Term
shall expire and terminate on the date specified in the Termination Notice,
which shall be at least seven (7) days after the giving of the Termination
Notice, and on the date specified therein this Lease and the Term and all rights
of Lessee under this Lease shall expire and terminate, it being the intention of
the Lessor and Lessee hereby to create conditional limitations, and Lessee shall
remain liable as provided in Article 15 and in accordance with those provisions
of this Lease which are specifically stated herein to survive the expiration or
other termination of this Lease.

     B. Notwithstanding the provisions of Section 14.0l.A, if there shall be an
Event of Default at any time or from time to time under the provisions of
subdivision (1) of Section 14.0l.A, Lessor may, in lieu of giving a Termination
Notice, at any time after the occurrence of any such Event of Default and during
the continuance thereof, institute an action for the recovery of the Fixed Rent
and/or Additional Rent in respect of which an Event of Default shall have
occurred and be continuing.  Neither the commencement of any such action for the
recovery of Fixed Rent and/or Additional Rent nor the prosecution thereof shall
be deemed a waiver of Lessor's right to give a Termination Notice in respect of
any such Event of Default during the continuance thereof and Lessor may,
notwithstanding the commencement and prosecution of any such action, give a
Termination Notice and terminate this Lease pursuant to Section 14.0l.A at any
time during the continuance of such Event of Default.

     C. If, at any time, (i) Lessee shall be comprised of two or more persons,
or (ii) Lessee's obligations under this Lease shall have been guaranteed by any
person other than Lessee, or (iii) Lessee's interest in this Lease shall have
been assigned, the word "Lessee," as used in subdivisions (4), (5) and (9) of
Section 14.0l.A, shall be deemed to mean any one or more of the persons
primarily or secondarily liable for Lessee's obligations under this Lease.  Any
monies received by Lessor from or on behalf of Lessee during the pendency of any
proceeding of the types referred to in said subdivisions (4), (5) and (9) of
Section 14.0l.A shall be deemed paid as compensation for the use and occupation
of the Demised Premises and the acceptance of any such

                                    Page 19 of 40
<PAGE>
compensation by Lessor shall not be deemed an acceptance of rent or a waiver on
the part of Lessor of any rights under Section 14.01.

     SECTION 14.02. In the event that this Lease shall be terminated as provided
in this Article, Lessor or Lessor's agents may, immediately, or at any time
thereafter, without further notice, enter upon and re-enter the Demised Premises
and possess and repossess itself thereof, by summary proceedings, ejectment or
otherwise, and have, hold and enjoy the Demised Premises and the right to
receive all income of and from the same.  No re-entry by Lessor pursuant to this
Article shall be deemed an acceptance of a surrender of this Lease nor shall it
absolve or discharge Lessee from any liability under this Lease.

     SECTION 14.03. In the event that this Lease shall be terminated as provided
in this Article, Lessor may, at any time or from time to time thereafter, relet
the Demised Premises or any part thereof, for such term or terms (which may be
greater or less than the period which would otherwise have constituted the
balance of the Term) and on such conditions (which may include concessions or
free rent, which shall, however, be amortized over the entire term for the
purpose of determining damages under Article 15) as Lessor may determine, to any
tenant which it may deem suitable and satisfactory and for any use and purpose
it may deem appropriate and may collect and receive the rents therefor.  Lessor
shall use commercially reasonable methods in making such reletting.  Lessor, at
its option, may make such repairs, alterations, additions, improvements,
decorations and other physical changes in and to the Demised Premises as Lessor
considers advisable or necessary in connection with any such reletting or
proposed reletting, without relieving Lessee of any liability under this Lease
or otherwise affecting any such liability.  Lessor shall in no way be
responsible or liable for any failure to relet the Demised Premises, or any part
thereof, or for any failure to collect any rent due upon such reletting.  Lessor
shall not in any event be required to pay Lessee (but shall credit Lessee, to
the extent set forth in Article 15, with) any sum received by Lessor on a
reletting of the Demised Premises, or any part thereof, whether or not in excess
of the rent reserved in this Lease.

     SECTION 14.04. Lessee, on its own behalf and on behalf of all persons
claiming through or under Lessee including all creditors, does hereby waive any
and all rights and privileges, so far as is permitted by law, which Lessee and
all such persons might otherwise have under any present or future law, to (i)
the service of any notice of intention to re-enter or institute legal
proceedings to that end, excluding service of process, (ii) redeem the Demised
Premises, (iii) re-enter or repossess the Demised Premises, or (iv) restore the
operation of this Lease, after Lessee shall have been dispossessed by a judgment
or by warrant of any court or judge, or after any re-entry by Lessor or after
any expiration or termination of this Lease and the Term, whether such
dispossess, re-entry, expiration or termination shall be by operation of law or
pursuant to the provisions of this Lease.  The words "re-enter," "re-entry" and
"re-entered" as used in this Lease shall not be deemed to be restricted to their
technical legal meanings.

     SECTION 14.05. In the event the Lessee shall dispute the validity or
amount, or the time or manner of payment of, any Rent claimed by Lessor to be
due from Lessee under this Lease, Lessee shall nevertheless pay the same and
such payment may be without prejudice to Lessee's position if Lessee so requests
at the time of payment.  If the dispute shall be finally determined in Lessee's
favor by a court of competent jurisdiction, Lessor shall within a reasonable
period of time not to exceed sixty (60) days pay Lessee the amount of Lessee's
overpayment of such rent.  Lessee's failure to observe and perform the
provisions of this Section shall be deemed a default under subdivision (1) of
Section 14.0l.A.

                 ARTICLE 15 - MEASURE OF DAMAGES IN EVENT OF DEFAULT

     SECTION 15.01.A. In the event that this Lease be terminated pursuant to
Article 14 as a result of an Event of Default on the part of the Lessee and
whether or not the Demised Premises be relet, Lessor shall be entitled to retain
all monies, if any, paid by Lessee to Lessor, whether as advance Rent or
otherwise, but such monies shall be credited by Lessor against any Rent due at
the time of such termination, or at Lessor's option, against any damages payable
by Lessee, and Lessor shall be entitled to recover from Lessee, and Lessee shall
pay to Lessor the following:

          (a) All Rent to the date upon which this Lease and the Term shall have
     terminated, and

          (b) All expenses reasonably incurred by Lessor in recovering
     possession of the Demised Premises (including summary proceedings),
     restoring the Demised Premises to good order and condition, maintaining the
     Demised Premises in good order and condition
                                    Page 20 of 40
<PAGE>

     while vacant, altering or otherwise preparing the same for reletting, and
     in reletting the Demised Premises (including reasonable and customary
     brokerage commissions and legal expenses), the same to be paid by Lessee to
     Lessor on demand, and

          (c) The amount by which the rent which, but for the termination of
     this Lease, would have been payable under this Lease from the date of
     termination to the Expiration Date exceeds the rental and other income, if
     any, collected by Lessor in respect of the Demised Premises, or any part
     thereof, subject nevertheless to the provisions of Section 14.03, said
     amount to be due and payable by Lessee to Lessor on the several days on
     which the Rent reserved in this Lease would have become due and payable for
     the period which otherwise would have constituted the unexpired portion of
     the Term (that is to say, upon each of such days Lessee shall pay to Lessor
     the amount of deficiency then existing).

     B. Whether or not Lessor shall have collected any monthly deficiencies
aforesaid, Lessor shall be entitled to recover from Lessee on demand, as and for
liquidated damages, a lump sum payment equal to the amount by which the Fixed
Rent and Additional Rent payable hereunder for the period which otherwise would
have constituted the unexpired portion of the Term (due account being taken of
amounts, if any, collected under clause [c] of Section 15.0l.A, and conclusively
presuming the Additional Rent to be the same as was payable for the year
immediately preceding such termination or re-entry and thereafter increasing by
three (3%) percent per annum) exceeds the then rental value of the Demised
Premises for the same period both discounted at a rate equal to then applicable
Treasury Rate to present value.  If the Demised Premises or any part thereof be
relet by Lessor for the unexpired portion of the Term, or any part thereof,
before presentation of proof of such liquidated damages to any court, commission
or tribunal, the amount of rent reserved upon such reletting shall be deemed
PRIMA FACIE to be the fair and reasonable rental value for the part or the whole
of the Demised Premises so relet during the term of the reletting.  Nothing
herein contained shall limit or prejudice the right of the Lessor to prove for
and obtain as damages by reason of such termination an amount equal to the
maximum allowed by any statute or rule of law in effect at the time when, and
governing the proceedings in which, such damages are to be proved, whether or
not such amount be greater or less than the amount of liquidated damages
referred to above (due account to be taken, however, of the amounts, if any,
collected under this Article 15).

     SECTION 15.02. In no event shall Lessee be entitled to receive any excess
of the rental and other income collected by Lessor in respect of the Demised
Premises over the sums payable by Lessee to Lessor hereunder.  In no event shall
Lessee be entitled in any suit for the collection of damages pursuant to this
Article to a credit in respect of any such rental and other income, except to
the extent that such rental and other income is allocable to the portion of the
Term in respect of which such suit is brought and is actually received by Lessor
prior to the entry of judgment in such suit.

     SECTION 15.03. Separate actions may be maintained by Lessor against Lessee
from time to time to recover any damages which, at the commencement of any such
action, have then or theretofore become due and payable to Lessor under Article
14, without waiting until the end of the Term and without prejudice to Lessor's
right to collect damages thereafter.

                             ARTICLE 16 - INDEMNIFICATION

     SECTION 16.01. Notwithstanding that joint or concurrent liability may be
imposed upon either party by statute, ordinance, rule, regulation, order or
court decision, and notwithstanding any insurance furnished by either party
pursuant hereto or otherwise, Lessee shall and does hereby indemnify and hold
Lessor and its agents, officers, directors, and employees, harmless from and
against any and all loss, liability, fines, suits, claims, obligations, damages,
penalties, demands and actions, and costs and reasonable expenses of any kind or
nature (including architects', engineers' and attorneys' fees) due to or arising
out of any of the following:

          (a) any work or thing done in, on or about the Demised Premises,
     Building or the Property or any part thereof or any use, possession,
     occupation, condition, operation, maintenance, repair or management of the
     Demised Premises, Building or the Property or any part thereof, by Lessee
     or anyone claiming through or under Lessee or the respective employees,
     agents, licensees, contractors, servants or sublessees of Lessee or any
     such person;

                                    Page 21 of 40
<PAGE>
          (b) any act or omission on the part of Lessee or any person claiming
     through or under Lessee, or the respective employees, agents, licensees,
     invitees, contractors, servants or sublessees of Lessee or any such person;
     or

          (c) any accident or injury to any person (including death) or damage
     to property (including loss of property) occurring in, on, or about the
     Demised Premises, Building or the Property or any part thereof, due to the
     act or omission by Lessee, its employees, agents, licensees, invitees,
     contractors or servants.

     The provisions of this Section 16.01 shall survive the expiration or
termination of this Lease.  Any sums payable by Lessee to Lessor under this
Section 16.01 shall be due and payable on demand.

     SECTION 16.02. Lessor and Lessor's agents, officers, directors, and
employees shall not be liable for any of the following, however caused, other
than by negligent or wilful acts: (a) failure of any Utility Service, (b) damage
to Lessee's property on the Demised Premises caused by or resulting from any
cause whatsoever, including explosion, falling plaster, vermin, smoke, gasoline,
oil, Hazardous Materials, steam, gas, electricity, earthquake, subsidence of
land, hurricane, tornado, flood, wind or similar storms or disturbances or
water, rain, ice or snow which may be upon, or leak or flow from, any street,
road, parking lot, sewer, gas main or subsurface area, or from any part of the
Property, or leakage of gasoline, oil or other substances from pipes, pipelines,
appliances, storage tanks, sewers or plumbing works in or at the Property, or
from any other place, or from the breaking of any electrical wire or the
breaking, bursting or leaking of water or Hazardous Materials from any plumbing
or sprinkler system, or any other pipe or storage tanks in, on, under or about
the Property, (c) interference with light or other incorporeal hereditaments,
and (d) loss by theft or otherwise of Lessee's Property or the property of any
person claiming through or under Lessee.  Any employees of Lessor to whom any
property shall be entrusted by or on behalf of Lessee shall be deemed to be
acting as Lessee's agents with respect to such property and neither Lessor nor
Lessor's agents shall be liable for any loss or for damage to any such property
by theft or otherwise.  This Section 16.02 shall not be construed as a provision
for indemnification.

     SECTION 16.03. Except as otherwise provided for in this Lease, Lessor shall
and does hereby agree to indemnify, defend and hold harmless Lessee and Lessee's
agents from and against any and all loss, liability, fines, suits, claims,
obligations, damages, penalties, demands and actions, and costs and reasonable
expenses of any kind or nature (including architects' and attorneys' fees) due
to or arising out of the negligence or willful misconduct of Lessor, its agents,
officers, directors and employees.  In case of any obligation of Lessor to
indemnify Lessee pursuant to this Section, such obligation shall be subject to
and conditioned upon (x) the receipt by Lessor of prompt written notice of the
claim with respect to which indemnification is sought and (y) Lessor's having
had reasonable opportunity to conduct the defense of such claim in such manner
as it deems appropriate, with the full cooperation of Lessee, and using counsel
reasonably acceptable to Lessor.

                        ARTICLE 17 - MECHANICS AND OTHER LIENS

     SECTION 17.01. If any mechanic's, laborer's or materialman's lien shall be
at any time be filed against the Demised Premises, Building or Property, or any
part thereof with respect to any work done, or caused to be done, or labor or
materials furnished, or caused to be furnished, by Lessee or anyone claiming
through or under Lessee (except for Lessor's Work), Lessee, within thirty (30)
days after notice of the filing thereof, shall cause the same to be discharged
of record by payment, deposit, bond, order of a court of competent jurisdiction
or otherwise.  If Lessee shall fail to cause such lien to be discharged within
the period aforesaid, then, in addition to any other right or remedy, Lessor
may, but shall not be obligated to, discharge the same by bonding proceedings,
if permitted by law (and if not so permitted, by deposit in court).  Any amount
so paid by Lessor, including all reasonable and actual costs and expenses paid
by Lessor in connection therewith, together with interest thereon at the maximum
legal rate from the respective dates of Lessor's so paying any such amount, cost
or expense, shall constitute Additional Rent payable by Lessee under this Lease
and shall be paid by Lessee to Lessor on demand.

                              ARTICLE 18 - CONDEMNATION

     SECTION 18.01. If the whole of the Demised Premises, or such part thereof
as will render the remainder Untenantable, shall be acquired or condemned for
any public or quasi-public use or purpose, this Lease and the Term shall end as
of the date of vesting of title in the
                                    Page 22 of 40
<PAGE>
condemning authority with the same effect as if said date were the Expiration
Date.  If only a part of the Demised Premises shall be so acquired or condemned
then, except as otherwise provided in this Article, this Lease and the Term
shall continue in force and effect but, from and after the date of the vesting
of title, the Fixed Rent shall be an amount which bears the same ratio to the
Fixed Rent payable immediately prior to such condemnation pursuant to this Lease
as the value of the untaken portion of the Demised Premises (appraised after
taking and repair of any damage to the Demised Premises pursuant to this
Section) bears to the value of the entire Demised Premises immediately before
the taking.  The value of the Demised Premises before and after the taking shall
be determined for the purposes of this Section by an independent licensed
appraiser chosen by Lessor.  If more than sixty (60%) percent of the total area
of the Building included in the Demised Premises immediately prior to
acquisition or condemnation is so acquired or condemned, or if by reason of such
acquisition or condemnation, Lessee no longer has reasonable means of access to
the Demised Premises, then in such event, either party, may give notice to the
other party within sixty (60) days next following the date upon which Lessee
have received notice of vesting of title, thirty (30) days notice of termination
of this Lease.  In the event any such thirty (30) day notice of termination is
given by Lessor or Lessee, this Lease and the Term shall terminate upon the
expiration of said thirty (30) days with the same effect as if that date were
the Expiration Date.  If a part of the Demised Premises shall be so acquired or
condemned, and the Term shall not be terminated pursuant to the provisions of
this Section, Lessor, at Lessor's expense, shall restore that part of the
Demised Premises not so acquired or condemned to a self-contained unit.  In the
event of any termination of this Lease and the Term pursuant to the provisions
of this Section, the Fixed Rent and Additional Rent shall be apportioned as of
the date of sooner termination and any prepaid portion of the Fixed Rent and
Additional Rent for any period after such date shall be refunded by Lessor to
Lessee, subject to the claims, if any, of Lessor against Lessee hereunder or
otherwise.

     SECTION 18.02. In the event of any acquisition or condemnation of all or
part of the Demised Premises for any public or quasi-public use or purpose,
Lessor shall be entitled to receive the entire award for such acquisition or
condemnation, Lessee shall have no claim against Lessor or the condemning
authority for the value of any unexpired portion of the Term and Lessee hereby
expressly assigns to Lessor all of its right, title and interest in and to any
such award, and also agrees to execute any and all further documents that may be
required in order to facilitate the collection thereof by Lessor.  Nothing
contained in this Section shall be deemed to prevent Lessee from making a
separate claim in any condemnation proceeding for moving expenses and for the
value of any Lessee's Property which would be removable at the end of the Term
pursuant to the provisions hereof, directly against any Governmental Authority
authorized to exercise the power of eminent domain, provided that applicable
statutes permit such awards and any award to Lessor is not diminished or
adversely affected thereby.

     SECTION 18.03. The terms "condemnation" and "acquisition" as used in this
Article shall include any agreement in lieu of or in anticipation of the
exercise of the power of eminent domain between Lessor and/or any Superior
Mortgage and any Governmental Authority authorized to exercise the power of
eminent domain.

                      ARTICLE 19 -  COVENANT OF QUIET ENJOYMENT

     SECTION 19.01. If and so long as no Event of Default shall have occurred
and be continuing, Lessor covenants and agrees that Lessee may peaceably and
quietly enjoy the Demised Premises and Lessee's possession of the Demised
Premises will not be disturbed by Lessor, its successors and assigns, subject,
however, to the terms of this Lease (including those set forth in Sections 24.01
and 24.02), the Mortgage, Superior Lease and any and/or all other agreements and
any amendments thereto, to which this Lease is subordinated.

                  ARTICLE 20 - WAIVER OF COUNTERCLAIM AND JURY TRIAL

     SECTION 20.01. In the event that Lessor shall commence any summary or other
proceedings or action for non-payment of Rent hereunder, Lessee shall not
interpose any counterclaim of any nature or description in such proceeding or
action, unless such non-interposition would effect a waiver of Lessee's right to
assert such claim against Lessor in a separate action or proceeding.  The
parties hereto waive a trial by jury on any and all issues arising in any action
or proceeding between them or their successors under or in any way connected
with this Lease or any of its provisions, any negotiations in connection
therewith, the relationship of Lessor and Lessee, or Lessee's use or occupation
of the Demised Premises, including any claim of injury or any emergency or other
statutory remedy with respect thereto.  The provisions of this Article shall
survive the expiration or other termination of this Lease.

                                 ARTICLE 21 - NOTICES

     SECTION 21.01.A. Except as otherwise expressly provided in this Lease, any
bills, statements, notices, demands, requests, consents or other communications
given or required to be given under this Lease shall be effective only if
rendered or given in writing and

          (a) If to Lessee, then, at the option of Lessor, (i) addressed to
     Lessee's address as set forth in this Lease with a copy thereof to Lessee
     at One Meadowlands Plaza, East Rutherford, New Jersey 07073, Attention:
     General Counsel, or to such other address as Lessee may designate as its
     new address for such purpose by notice given to Lessor in accordance with
     the provisions of this Section, or (ii) delivered personally to Lessee, or
     (iii) by overnight courier,

          (b) If to Lessor, sent by personal delivery or overnight courier,
     addressed to Lessor at Lessor's address as set forth in this Lease, with a
     copy thereof to Hirsch & Katz, LLP, 595 Stewart Avenue, Suite 400, Garden
     City, New York 11530, Attention: Steven C. Hirsch, Esq., or to such other
     address as Lessor may designate as its new address for such purpose by
     notice given to Lessee in accordance with the provisions of this Section.

     B. Any such bill, statement, notice, demand, request, consent or other
communication shall be deemed to have been rendered or given: (i) on the date
delivered, if delivered to Lessee personally, or by overnight courier and
(ii) on the expiration of five (5) days after mailing, if mailed to Lessor or
Lessee as provided in this Section.  Any notice by a party signed by counsel for
such party shall be deemed a notice signed by such party.

                 ARTICLE 22 - WAIVERS AND SURRENDERS TO BE IN WRITING

     SECTION 22.01. The receipt of full or partial Rent by Lessor with knowledge
of any breach of this Lease by Lessee or of any default on the part of the
Lessee in the observance or performance of any of the provisions or covenants of
this Lease shall not be deemed to be a waiver of any such provision, covenant or
breach of this Lease, PROVIDED, HOWEVER, that acceptance of a payment of Rent
shall be valid PRO TANTO.  No waiver or modification by Lessor, unless in
writing, and signed by Lessor, shall discharge or invalidate any provision or
covenant or affect the right of Lessor to enforce the same in the event of any
subsequent breach or default.  The failure on the part of Lessor to insist in
any one or more instances upon the strict performance of any of the provisions
or covenants of this Lease, or to enforce any covenant or provision herein
contained or to exercise any right, remedy or election herein contained
consequent upon a breach of any provision of this Lease, shall not affect or
alter this Lease or be construed as a waiver or relinquishment for the future of
such one or more provisions or covenants or of the right to insist upon strict
performance or to exercise such right, remedy or election, but the same shall
continue and remain in full force and effect with respect to any existing or
subsequent breach, act or omission, whether of a similar nature or otherwise.
The receipt by Lessor of any rent or any other sum of money or any other
consideration hereunder paid by Lessee after the termination, in any manner, of
the Term, or after the giving by Lessor of the Termination Notice, shall not
reinstate, continue or extend the Term, or destroy, or in any manner impair the
efficacy of any such Termination Notice, as may have been given hereunder by
Lessor to Lessee prior to the receipt of any such Rent, or other sum of money or
other consideration, unless so agreed to in writing and signed by Lessor.
Neither acceptance of the keys or any other act or thing done by Lessor or any
agent or employee shall be deemed to be an acceptance of a surrender of the
Demised Premises, or any part thereof, excepting only an agreement in writing
signed by Lessor.  No payment by Lessee or receipt by Lessor of a lesser amount
than the correct Rent shall be deemed to be other than a payment on account, nor
shall any endorsement or statement on any check, as distinguished from any
letter accompanying such check or payment, be deemed to effect or evidence an
accord and satisfaction, and Lessor may accept such check or payment without
prejudice to Lessor's right to recover the balance or pursue any other remedy in
this Lease provided.

     SECTION 22.02. No waiver or modification by Lessee, unless in writing, and
signed by Lessee, shall discharge or invalidate any provision or covenant or
affect the right of Lessee to enforce the same in the event of any subsequent
breach or default.  The failure on the part of Lessee to insist in any one or
more instances upon the strict performance of any of the provisions or covenants
of this Lease, or to enforce any covenant or provision herein contained or to
exercise any right, remedy or election herein contained consequent upon a breach
of any provision of this Lease, shall not affect or alter this Lease or be
construed as a waiver or relinquishment for the future of such one or more
provisions or covenants or of the right to insist
                                    Page 24 of 40
<PAGE>

upon strict performance or to exercise such right, remedy or election, but the
same shall continue and remain in full force and effect with respect to any
existing or subsequent breach, act or omission, whether of a similar nature or
otherwise.

                            ARTICLE 23 - RIGHTS CUMULATIVE

     SECTION 23.01. Each right and remedy of Lessor shall be cumulative and to
the extent permitted by law, the exercise or beginning of the exercise by Lessor
of any one or more of the rights or remedies of such party shall not preclude
the simultaneous or later exercise by Lessor of any or all other rights or
remedies; PROVIDED, HOWEVER, that this sentence shall not be construed to
entitle Lessor to satisfaction of more than one remedy in respect of a
particular breach.  In the event of any breach or threatened breach by Lessee or
any persons claiming through or under Lessee of any of the agreements, terms,
covenants or conditions contained in this Lease, Lessor shall be entitled to
enjoin such breach or threatened breach (if entitled to do so at law or in
equity or by statute or otherwise) and shall have the right to invoke any right
or remedy allowed by law or in equity or by statute or otherwise as if re-entry,
summary proceedings or other specific remedies were not provided for in this
Lease.

                    ARTICLE 24 - CONVEYANCE; LIABILITY OF PARTIES

     SECTION 24.01. The term "Lessor" as used herein shall mean and include only
the owner or owners at the time in question of the Lessor's interest in this
Lease so that in the event of any transfer or transfers (by operation of law or
otherwise) of Lessor's entire interest in this Lease, Lessor herein named (and
in the case of any subsequent transfers or conveyances, the then transferor)
shall be and hereby is automatically freed and relieved, from and after the date
of such transfer or conveyance, of all liability in respect of the performance
of any covenants or obligations on the part of the Lessor contained in this
Lease thereafter to be performed, provided that the transferee shall be deemed
to have assumed and agreed to perform subject to the limitation of this Article
(and without further agreement between or among the parties or their successors
in interest, and/or the transferee) and only during and in respect of the
transferee's period of ownership, all of the terms, covenants and conditions in
this Lease contained on the part of Lessor to be performed, which terms,
covenants, and conditions shall be deemed to "run with the land," it being
intended hereby that the terms, covenants and conditions contained in this Lease
or the part of the Lessor to be performed shall, subject as aforesaid, be
binding on Lessor, its successors and assigns, only during and in respect of
their respective successive periods of ownership.

     SECTION 24.02. In the event of a breach by Lessor of any provisions,
covenants or obligations of this Lease to be performed by Lessor, the monetary
liability of Lessor in relation to any such breach shall be limited to the
equity of Lessor in the Demised Premises, and Lessee shall look only to Lessor's
equity in the Demised Premises for the performance and observance of the terms,
covenants, conditions and obligations of this Lease to be performed or observed
by Lessor and for the satisfaction of Lessee's remedies for the collection of
any award, judgment or other judicial process requiring the payment of money by
Lessor in the event of a default in the full and prompt payment and performance
of any Lessor's obligations hereunder and in no event shall any of the partners
constituting Lessor (the "Partners"), nor the partners, shareholders, officers
or directors of Lessor or the Partners shall be liable for the performance of
Lessor's obligations under this Lease, nor shall any of the Partners assets be
liable to any levy, execution, restraint, award, claim of any kind whatsoever
arising out of, or in any way related to this Lease.

     SECTION 24.03. The term "Lessee" as used in this Lease shall mean and
include Lessee named herein and, during and in respect of their respective
successive periods of ownership, each subsequent owner or owners of the
leasehold estate created by this Lease.  For all purposes of this Lease and
without affecting the rights of, and obligations between, Lessee herein named
and any transferee, notwithstanding any transfer (by operation or law or
otherwise) of title to the leasehold estate created by this Lease by Lessee
herein named or by any subsequent owner of such estate and notwithstanding the
assumption by any transferee of the obligations of the Lessee hereunder, Lessee
herein named, as between Lessor and Lessee herein named, shall remain primarily
liable as primary obligor and not as a surety, for the full and prompt payment
and performance of Lessee's obligations hereunder and, without limiting the
generality of the foregoing or of Article 28, shall remain fully and directly
responsible and liable to Lessor for all acts and omissions on the part of any
transferee subsequent to it in violation of any obligation of this Lease.

                    ARTICLE 25 - CHANGES AND ALTERATIONS BY LESSEE

     SECTION 25.01.A. Lessee shall have no right to make any alteration, change,
additions or improvement, structural or otherwise (an "Alteration"), to the
Demised Premises or any appurtenances thereto without the prior written consent
of Lessor in each instance, which consent shall not be unreasonably withheld.

     B. If Lessor shall grant its consent to the making of an Alteration, then
the same shall (i) be performed at the sole cost and expense of Lessee, (ii) be
performed in a good and workmanlike manner, and in compliance with all
applicable Legal Requirements (including existing zoning requirements),
Insurance Requirements and Environmental Laws, (iii) be consistent with the use
of the Demised Premises provided for herein, (iv) not in any way render the
Demised Premises other than a complete, self containing operating unit, (v) in
the case of a structural alteration, be performed in accordance with plans and
specifications approved prior to the commencement of any work by the appropriate
Governmental Authorities and by Lessor, (vi) be of such nature so as not to
lessen the fair market value of the Demised Premises, and (vii) be performed
under the supervision of a licensed architect approved by Lessor and in
accordance with Lessor's STANDARD REQUIREMENTS FOR ALTERATIONS TO BE PERFORMED
BY LESSEES', as may be amended from time to time.

     SECTION 25.02.A. Any and all Alterations made in accordance with
Section 25.01 shall immediately become the property of Lessor, PROVIDED,
HOWEVER, that if, in accordance with the provisions of Sections 25.02.B and
29.02, Lessee shall have the option to and shall remove its trade fixtures,
provided that same are not affixed to or such removal would otherwise damage the
Demised Premises, then the same shall cease to be property of the Lessor upon
removal.

     B. Unless Lessor shall otherwise expressly indicate in writing at the time
of granting its consent to the making of a proposed Alteration, Lessee shall, as
and when provided in Section 29.02, restore the affected portion of the Demised
Premises to the state or condition thereof existing prior to the making of such
Alteration.

     C. Any and all contractors to be involved in performing work shall be
subject to Lessor's prior approval, which shall not be unreasonably withheld.

     D. Prior to commencing any work at the Demised Premises, Lessee shall
furnish Lessor with evidence reasonably satisfactory to Lessor of such insurance
as Lessor may require and such insurance shall be in full force and effect
during such work and will cover, by endorsement or otherwise, the risk during
the course of such work.

     E. In the event of any Alteration as provided for in this Article, the Rent
payable hereunder shall not be reduced or abated in any manner whatsoever,
except as specifically provided for in Article 3 hereof.

     F. No Alterations shall involve the removal of any fixtures, equipment or
other property in the Demised Premises which are not Lessee's property, unless
Lessor's prior written consent is first obtained and unless such fixtures,
equipment or other property shall be promptly replaced, at Lessee's expense and
free of superior title, liens and claims, with fixtures, equipment or other
property (as the case may be) of like utility and at least equal value (which
replaced fixtures, equipment or other property shall thereupon become the
property of Lessor), unless Lessor shall otherwise expressly consent in writing.

     SECTION 25.03. Notwithstanding anything herein to the contrary, Lessor
(which term shall mean Lessor and/or Lessor's affiliated general contractor)
shall have the right to bid on any and all Alterations pursuant to Article 25 of
this Lease.  In the event that Lessor is not the successful bidder, then in such
event, Lessor (which term shall mean Lessor and/or Lessor's affiliated general
contractor) shall be entitled to a general supervisory fee of Five (5%) percent
to supervise all such Alterations.

                          ARTICLE 26 - CERTIFICATE OF LESSEE

     SECTION 26.01. Lessee agrees at any time and from time to time, within
twenty (20) days after receiving written request by Lessor, to execute,
acknowledge and deliver a statement certifying (i) the Commencement Date and/or
Rent Commencement Date hereunder, (ii) that this Lease is unmodified and in full
force and effect (or if there have been modifications, that the Lease is in full
force and effect as modified and stating the modifications), (iii) the dates to
which the Fixed Rent and Additional Rent have been paid, and (iv) whether or not
to the knowledge of

                                    Page 26 of 40
<PAGE>

the signer of such statement (a) Lessor is in default in keeping, observing or
performing any term, covenant, agreement, provision, condition or limitation
contained in this Lease and, if in default, specifying each such default,
(b) either party is holding any funds under this Lease in which the other has an
interest (and, if so, specifying the party holding such funds and the nature and
amount thereof), and (c) there is any amount then due and payable to Lessee by
Lessor, it being intended that any such statement delivered pursuant to this
Section may be relied upon by Lessor, any mortgagee, superior lessor or any
person who may and does become a mortgagee, superior lessee, any person who may
and does become a purchaser or assignee of Lessor's interest in this Lease or
the mortgagee's interest in any mortgage or the Lessor's interest in the
Superior Lease.

                  ARTICLE 27 - ASSIGNMENTS, SUBLEASES AND MORTGAGES

     SECTION 27.01.A. Except as otherwise specifically provided in this Article,
neither this Lease, nor the Term and estate hereby granted, nor any part
thereof, nor the interest of Lessee in any sublease or the rental thereunder,
shall be assigned, mortgaged, pledged, encumbered or otherwise transferred by
Lessee or Lessee's legal representatives or successors in interest, by operation
of law or otherwise, and neither the Demised Premises, nor any part thereof, nor
any Lessee's Property, shall be encumbered in any manner by reason of any act or
omission on the part of Lessee or anyone claiming under or through Lessee, or
shall be sublet or be used or occupied or permitted to be used or occupied or
utilized for desk or storage space by anyone other than Lessee or for any
purpose other than as specifically permitted by this Lease, without the prior
written consent of Lessor in each case, which consent may be withheld for any
reason whatsoever.  If Lessee is other than a public company, a transfer
(including any issuance of stock) of an aggregate of fifty (50%) percent or more
stock, partnership interest or other equity interest in Lessee by any party or
parties in interest shall be deemed an assignment of this Lease.

     B. If Lessee is a corporation, upon at least thirty (30) days prior notice
to Lessor, this Lease in its entirety may be assigned without Lessor's consent
to a corporation into which Lessee merges or consolidates, or which controls, is
controlled by or under common control with Lessee, so long as the Demised
Premises continue to be used for the use described in Article 4 of this Lease;
the transfer is not principally for the purpose of transferring the leasehold
estate created hereby; the net worth of the assignee is at least equal to or in
excess of the net worth of Lessee at the time of execution of this Lease and
immediately prior to such assignment or the assignee can otherwise secure and
guaranty the payment to Lessor of all rent and any other amounts due from Lessee
pursuant to this Lease in a manner reasonably satisfactory to Lessor; the
assignee assumes by documents satisfactory to Lessor all of Lessee's obligations
to be performed under this Lease, and; provided such assignment shall be subject
to all of the other terms and conditions of this Lease.

     SECTION 27.02. If this Lease be assigned, whether or not in violation of
the provisions of this Lease, Lessor may collect rent from the assignee, and
Lessor shall be entitled to receive, as Additional, Rent, all the excess
consideration paid to Lessee in connection with such assignment as shall for any
period exceed the aggregate of the Rents payable under this Lease (the "Excess
Consideration").  Such Excess Consideration shall be reduced by the reasonable
cost of tenant improvements, rent concessions, and brokerage commissions
reasonably incurred by Lessee for such assignment, and the net amount thereof
shall be paid to Lessor either: (i) in a lump sum, (ii) or allocated to such
period on a straight line basis over the term of such assignment if paid in
installments, as the case may be, promptly after receipt thereof by Lessee.  The
provisions of the preceding sentence shall be in full force and effect
notwithstanding that Lessee has sought the protection of any provisions of the
bankruptcy law (as hereinafter defined) or if a petition has been filed against
Lessee under such bankruptcy law.  If the Demised Premises or any part thereof
be sublet or be used or occupied by anybody other than Lessee, whether or not in
violation of this Lease, Lessor may, after default by Lessee and expiration of
Lessee's time to cure such default, if any, collect rent from the sublessee or
occupant.  In either event, Lessor may apply the net amount collected to the
rents herein reserved, but no such assignment, subletting, occupancy or
collection shall be deemed a waiver of any of the provisions of Section 27.01,
or the acceptance of the assignee, sublessee or occupant as tenant, or a release
of Lessee from the further performance by Lessee of Lessee's obligations under
this Lease.  The consent by Lessor to an assignment, mortgaging or subletting
pursuant to any provision of this Lease shall not in any way be considered to
relieve Lessee from obtaining the express consent of Lessor for any other or
further assignment, mortgaging or subletting.  References in this Lease to use
or occupancy by anyone other than Lessee shall not be construed as limited to
sublessees and those claiming under or through sublessees but as including also
licensees and others claiming under or through Lessee, immediately or remotely.
The listing of any name other than that of Lessee on any door of the Demised
Premises or on any sign on the Demised Premises, or

                                    Page 27 of 40
<PAGE>

otherwise, shall not operate to vest in the person so named any right or
interest in this Lease or in the Demised Premises, or be deemed to constitute,
or serve as a substitute for, any prior consent of Lessor required under this
Article, and it is understood that any such listing shall constitute a privilege
extended by Lessor which shall be revocable at Lessor's will by notice to
Lessee.  Lessee agrees to pay to Lessor any reasonable counsel fees incurred by
Lessor in connection with any proposed assignment of Lessee's interest in this
Lease or any proposed subletting of the Demised Premises or any part thereof.
Neither any assignment of Lessee's interest in this Lease nor any subletting,
occupancy or use of the Demised Premises or any part thereof by any person other
than Lessee as provided in this Article, nor any application of any such rent as
provided in this Article shall, under any circumstances, relieve Lessee herein
named of its obligations fully to observe and perform the terms, covenants and
conditions of this Lease on Lessee's part to be observed and performed.

     SECTION 27.03.A. Notwithstanding anything contained in Sections 27.01 and
27.02, in the event that, at any time or from time to time during the Term,
Lessee desires to sublet all or any part of the Demised Premises, Lessee shall
notify Lessor of such desire and shall: (i) submit to Lessor in writing the name
and address of the proposed subtenant, a reasonably detailed statement of the
proposed subtenant's business, reasonably detailed financial references for the
proposed subtenant and any other information reasonably requested by Lessor, and
(ii) submit to Lessor a copy of the proposed sublease.


     B. If a proposed assignment or sublease requires Lessor's consent, then
upon receipt of such notice Lessor shall thereupon have the option and right,
exercisable within ten (10) days of receipt of such notice from Lessee, to
terminate this Lease effective as of a date specified by Lessor in such notice
which date shall not be later than thirty (30) days after the date of Lessor's
notice.  Notwithstanding the foregoing, Lessor shall not have the right to
terminate this Lease in connection with a collateral assignment of the Lease
which Lessor has consented to.

     C. If within fifteen (15) days after Lessee shall have requested the
consent of Lessor to any assignment or subletting under this Article, and shall
have submitted all items required hereby, Lessor does not exercise its option to
terminate this Lease, the term of the proposed assignment or sublease may
commence upon Lessor's consent, which consent may not be unreasonably withheld,
it being agreed that if within such fifteen (15) day period Lessor does not
advise Lessee that such consent is not granted, such consent shall be deemed
granted by Lessor.  Lessor, however, shall not in any event be obligated to
consent to the proposed sublease or the commencement of the term unless: (i) in
the reasonable judgment of Lessor the proposed subtenant is of a character and
financial worth such as is in keeping with the standards of Lessor in those
respects for the Demised Premises, and the nature of the proposed subtenant's
business and its reputation are in keeping with the character of the Demised
Premises and the use thereof, (ii) the purpose for which the proposed subtenant
intends to use the portion of the Demised Premises sublet to it are uses
expressly permitted by and not expressly prohibited by this Lease; (iii) the
proposed sublease shall prohibit any further assignment or subletting, except in
accordance with the terms of this Lease; (iv) no Event of Default shall have
occurred and be continuing and (v) Lessee shall reimburse Lessor for all
reasonable costs that may be incurred by Lessor in connection with any sublease
or assignment, including the costs of making investigations as to the
acceptability of a proposed subtenant or assignee and legal costs incurred in
connection with the granting of any requested consent.

     D. With respect to each and every subletting authorized by the provisions
of this Article it is further agreed and understood between Lessor and Lessee
that: (i) the subletting shall be, and each such sublease shall expressly
provide that is, subject and subordinate at all times and in all respects, to
this Lease, (ii) no subletting shall be for a term ending later than one day
prior to the Expiration Date originally provided for herein and that part, if
any, of the proposed term of any sublease which shall extend beyond a date one
day prior to the Expiration Date originally provided for herein (or any sooner
date of the expiration of the term or termination of this Lease) is hereby
deemed to be a nullity, (iii) there shall be delivered to Lessor, within ten
(10) days after the commencement of the term of the proposed sublease, notice of
such commencement and a fully executed copy of the proposed sublease (unless
previously submitted) and (iv) Lessee shall pay to Lessor, as Additional Rent,
all of the rents, additional charges and other consideration arising from such
subletting as shall for any period exceed the aggregate of the Rents payable
under this Lease for the subleased space of the same period less the brokerage
commissions and attorneys' fees and disbursements reasonably incurred by Lessee
for such subletting, allocated to such period on a straight line basis over the
term of such subletting.

     E. Anything herein contained to the contrary notwithstanding: (i) Lessee
shall not advertise but may list its space for subletting or assignment, and may
list its space at a rental rate

                                    Page 28 of 40
<PAGE>

lower than the rental rate then being paid by Lessee to Lessor only with respect
to subletting (but not assignment) and (ii) No assignment or subletting shall be
made to any person or entity which shall at that time otherwise be a tenant,
sub-tenant or other occupant of any part of the Property or which shall within
the prior six (6) months have been negotiating with Lessor to become such a
tenant, sub-tenant or occupant of the Property, unless such person or entity
desires the Demised Premises solely for expansion purposes and not for
relocating its business and Lessor has no space available to satisfy such person
or entity's needs.

                              ARTICLE 28 - SUBORDINATION

     SECTION 28.01. Subject to the provisions of Section 28.02, this Lease, and
all rights of Lessee hereunder, are and shall be subject and subordinate in all
respects to (a) all present and future ground leases, overriding leases and
underlying leases and/or grants of term of the Property, the Building, the
Building Equipment and/or any appurtenance thereto of which Lessor has notified
Lessee (collectively, the "Superior Lease"), (b) all mortgages and building loan
agreements, including leasehold mortgages, deeds of trust, and building loan
agreements, which may now or hereafter affect the Property, the Building, the
Building Equipment and/or any appurtenance thereto, of which Lessor has notified
Lessee (collectively, the "Mortgage"), whether or not the Mortgage shall also
cover other land and/or buildings, and (c) each and every advance made or
hereafter to be made under the Mortgage and to all renewals, modifications,
replacements, substitutions and extensions of any Superior Lease and the
Mortgage and spreaders and consolidations of the Mortgage.  The provisions of
this Section shall be self-operative and no further instrument of subordination
shall be required.  In confirmation of such subordination, Lessee shall promptly
execute and deliver, at its own cost and expense, an instrument in recordable
form to evidence such subordination.  If, in connection with the obtaining,
continuing or renewing of financing for which the Demised Premises or the
interest of the lessee under the Superior Lease represents collateral in whole
or in part, a bank, insurance company or other lender shall request reasonable
modifications of this Lease as a condition of such financing, Lessee will not
unreasonably withhold or delay its consent thereto, provided that such
modifications do not increase the monetary obligations of Lessee under this
Lease or materially increase the other obligations of Lessee hereunder or
materially and adversely affect the rights of Lessee under this Lease.
Notwithstanding the foregoing, Lessor represents that as of the date hereof, the
Property and Building are not encumbered by a Superior Lease or Mortgage.

     SECTION 28.02. The subordination provided in Section 28.01 shall be
effective as between Lessee herein named and any lessor under a future Superior
Lease, or any holder of a future Mortgage, as the case may be, only if such
lessor or holder delivers to Lessee an agreement providing in substance, that if
and so long as no Event of Default shall have occurred and be continuing, this
Lease shall continue upon its then executory terms and conditions and possession
of the Demised Premises held by Lessee herein named will not be disturbed by
such person in the event of a default under the underlying lease or the
Mortgage, as the case may be.  The foregoing provisions of this Section shall
endure to the benefit of Lessee herein named and shall apply notwithstanding
that, as a matter of law, this Lease may terminate upon the termination of the
Superior Lease, or the foreclosure (including judgment of foreclosure and sale)
of the Mortgage.

     SECTION 28.03. If at any time prior to the expiration of the Term, the
holder of the Mortgage shall become the owner of the Demised Premises as a
result of foreclosure of its mortgage or by reason of an assignment of the
lessee's interest under any such lease or conveyance of the Demised Premises,
Lessee agrees, at the election and upon demand of any owner of the Demised
Premises, or of the holder of any Mortgage or Superior Lease (including a
leasehold mortgage) in possession of the Demised Premises, to attorn, from time
to time, to any such owner, or lessee, upon the then executory terms and
conditions of this Lease, provided that such owner, holder or lessee, as the
case may be, shall then be entitled to possession of the Demised Premises.  No
such owner, holder or lessee shall be liable for any previous acts or omission
of Lessor under this Lease (except that this provision shall not be construed to
relieve such person from any obligation thereafter to be performed), nor shall
such owner, holder or Lessee be subject to any offset which shall have
theretofore accrued to Lessee against Lessor, or be bound by any previous
modification of this Lease, not expressly provided for in this Lease, entered
into after the date of the Mortgage, or Superior Lease, or by any previous
prepayment of more than one month's Fixed Rent.  The foregoing provisions of
this Section shall enure to the benefit of any such owner, holder or lessee,
shall apply notwithstanding that, as a matter of law, this Lease may terminate
upon the termination of the Superior Lease, or the foreclosure (including
judgment of foreclosure and sale) of the Mortgage, shall be self-operative upon
any such demand, and no further instrument shall be required to give effect to
said provisions.  Lessee, however, upon demand of any such owner, holder or
lessee, agrees to execute, from time

                                    Page 29 of 40
<PAGE>
to time, instruments in confirmation of the foregoing provisions of this
Section, acknowledging such attornment and setting forth the terms and
conditions of its tenancy.  Nothing contained in this Section shall be construed
to impair any right otherwise exercisable by any such owner, holder or lessee.

                 ARTICLE 29 - SURRENDER; REMOVAL OF LESSEE'S PROPERTY

     SECTION 29.01. On the last day of the Term or on the earlier termination of
the Term, Lessee shall peaceably and quietly leave, surrender and deliver the
Demised Premises to Lessor, together with (a) all alterations, changes,
additions and improvements, which may have been made upon the Demised Premises,
and (b) except for Lessee's Property, all fixtures and articles of personal
property of any kind or nature which Lessee may have installed or affixed on,
in, or to the Demised Premises for use in connection with the operation and
maintenance of the Demised Premises (whether or not said property be deemed to
be fixtures), all of the foregoing to be surrendered in good, substantial and
sufficient repair, order and condition, reasonable use, wear and tear, and
damage by fire or other casualty, excepted, and free of occupants and
sublessees.

     SECTION 29.02. On or prior to the Expiration Date or any earlier
termination of this Lease, Lessee shall remove Lessee's Property, and any items
referred to in clauses (a) or (b) of Section 29.01, which Lessor shall request
Lessee to remove (unless Lessor shall have waived such right as to any item
referred to in clause (a) of Section 29.01 at the time of the granting of
consent with respect thereto under Article 25), and Lessee shall pay or cause to
be paid the cost of repairing or remedying any damage caused thereby, provided
that no item of Lessee's Property may be removed if its removal would impair the
integrity (structural or otherwise) of the Building or Building Equipment.  All
property not so removed shall be deemed abandoned and may either be retained by
Lessor as its property or disposed of, without accountability, at Lessee's sole
cost, expense and risk, in such manner as Lessor may see fit.

     SECTION 29.03. If the Demised Premises are not surrendered in accordance
with the provisions of this Article upon the expiration or termination of this
Lease, Lessor shall have all rights given at law or in equity, in the case of
holdovers, to remove Lessee and anyone claiming through or under Lessee.  In any
event, Lessee shall and does hereby indemnify Lessor against all loss or
liability arising from delay by Lessee in so surrendering the Demised Premises,
including any claims made by and succeeding lessees founded on such delay.
Lessee expressly waives, for itself and for any person claiming through or under
Lessee (including creditors), any rights which Lessee or any such person may
have under the provisions of any law in connection with any holdover summary
proceedings which Lessor may institute to enforce the provisions of this
Article.  Lessee's obligations under this Article shall survive the expiration
or termination of this Lease.

     SECTION 29.04. Lessee acknowledges the extreme importance to Lessor that
possession of the Demised Premises be surrendered at the expiration or sooner
termination of this Lease.  In the event that Lessee fails to vacate the Demised
Premises at the expiration or sooner termination of this Lease, Lessee shall be
obligated to pay Lessor damages in an amount equal to twice the amount of annual
Fixed Rent and Additional Rent provided for on the day preceding the Expiration
Date for such period of time that Lessee holds over on a per diem basis.

                              ARTICLE 30 - RENEWAL TERM

     SECTION 30.01. Lessee named herein, shall have the right, at its option, to
extend this Lease for a term ("Renewal Term") of five (5) years (to commence on
the Expiration Date originally provided for herein and to end at noon on the
Fifth (5th) Anniversary of such Expiration Date originally provided for herein)
by giving Lessor notice of such election at any time but not less than Nine (9)
months prior to the Expiration Date originally provided for herein (time being
of the essence with respect thereto), and upon the giving of such notice this
Lease thereupon shall, subject to the provisions of Section 30.02, be
automatically extended for the Renewal Term with the same force and effect as if
the Renewal Term had been originally included in the Term, without the execution
of any further instrument.

     SECTION 30.02. Any notice of election to exercise the option to extend as
hereinbefore provided must be in writing and sent to Lessor as provided in
Article 21.  Neither the option granted to Lessee in this Article to extend the
Term, nor the exercise of such option by Lessee, named herein shall prevent
Lessor from exercising any option or right granted or reserved to Lessor in this
Lease to terminate this Lease, and the effective exercise of any such right of
termination by Lessor shall terminate any such renewal or extension and any
right of Lessee to
                                    Page 30 of 40
<PAGE>

any such renewal or extension, whether or not Lessee shall have exercised any
such option to extend the Term.  Any such option or right on the part of Lessor
to terminate this Lease pursuant to the provisions hereof shall continue during
any Renewal Term.

     SECTION 30.03. All of the terms, covenants and conditions of this Lease
shall continue in full force and effect during the Renewal Term except that
(i) the Fixed Rent for the Renewal Term shall be as provided in Section 30.04
(all other rent and charges payable by Lessee remaining unaffected), and
(b) there shall be no further privilege of extension of this Lease beyond the
Renewal Term.

     SECTION 30.04.A. During the Renewal Term, Lessee shall pay to Lessor annual
Fixed Rent, at the same times and in the same manner as in the Term originally
provided for, at the annual rate equal to the annual fair rental value of the
Demised Premises (with deduction for the cash value of free rent and leasehold
improvements), which renewing, non-equity tenants are then receiving in
connection with a lease for comparable space in a building of the same age,
quality, size, location, services, amenities, quality of construction and
appearance to that of the Building on the date of the commencement of the
Renewal Term with a term equal to the Renewal Term and otherwise containing the
same provisions as this Lease contains, as determined by agreement between
Lessor and Lessee.  If, prior to the commencement of the Renewal Term, Lessor
and Lessee are unable to agree on the amount of the annual Fixed Rent during the
Renewal Term, then in such event, the determination of such annual fair rental
value shall be made by arbitration pursuant to the provisions of
Section 30.04.B. hereof.  If the Renewal Term shall commence prior to
determination of the amount of annual Fixed Rent payable during the Renewal
Term, either by agreement or by decision of the arbitrators, Lessee, in the
meantime, shall pay the monthly installments of Fixed Rent at the annual rate
payable under this Lease for the year ending on the Expiration Date originally
provided for herein.  If monthly installments of the amount agreed upon by
Lessor and Lessee, or found by the arbitrators, shall be greater than such
amount, then Lessee, forthwith after such agreement or arbitrator's decision,
shall pay to Lessor, for the period from the commencement of the Renewal Term to
the last day of the calendar month in which the agreement or the arbitrators'
decision takes effect, the difference between the monthly installments actually
paid and the monthly installments which should have been paid in accordance with
such agreement or arbitrators' decision, together with interest at the prime
rate plus two (2%) percent from the respective due dates of each monthly
installment to the date of payment pursuant to this paragraph; and, thereafter,
Lessee shall pay the monthly installments at the new rate.  In no event shall
the annual Fixed Rent during the Renewal Term be less than the annual Fixed Rent
payable immediately prior to the Renewal Term.

     B.(1) In the event that Lessor and Lessee are unable to agree on the amount
of the annual Fixed Rent during the Renewal Term, then either Lessor or Lessee
(hereinafter referred to as the "Initiating Party") may give the other party
(hereinafter called the "Responding Party") a notice designating the name and
address of the arbitrator designated by the Initiating Party to act on its
behalf in the arbitration process hereinafter described (the "Review Notice").

     (2) If the Initiating Party gives a Review Notice, then within twenty (20)
days after giving of such Review Notice, the Responding Party shall give notice
to Initiating Party specifying in such notice the name and address of the
arbitrator designated by the Responding Party to act on its behalf.  In the
event the Responding Party shall fail to give such notice within such twenty
(20) day period, then the appointment of such arbitrator shall be made in the
same manner as hereinafter provided for the appointment of a third arbitrator in
a case where two arbitrators are appointed hereunder and the parties are unable
to agree to such appointment.  The two arbitrators so chosen shall meet within
thirty (30) days after the second arbitrator is appointed and shall exchange
sealed envelopes each containing such arbitrators written determination of the
fair market rent of the Demised Premises based on the criteria set forth in
Section 30.04.A. The fair market rent specified by Lessor's arbitrator shall be
called the "Lessor's Submitted Value" and the fair market rent specified by
Lessee's arbitrator shall be called the "Lessee's Submitted Value."  Copies of
such written determinations shall promptly be sent to both Lessor and Lessee.
Any failure of either such arbitrator to meet and exchange such determinations
shall be acceptance of the other party's arbitrator's determination as to fair
market rent, if, and only if, such failure persists for five (5) days after
notice to whom such arbitrator is acting, and, provided that such five (5) day
period shall be extended by reason of any Unavoidable Delay.  If the higher
determination of the fair market rent for the Demised Premises is not more than
one hundred and five (105%) percent of the lower determination of the fair
market rent, then the fair market rent for such space shall be deemed to be the
average of the two determinations.  If, however, the higher determination is
more than one hundred and five (105%) percent of the lower determination, then
within ten (10) days of the date the arbitrators submitted their respective fair
market rent determinations, the two arbitrators shall appoint a third
arbitrator.  In the event of

                                    Page 31 of 40
<PAGE>
their being unable to agree upon such appointment within ten (10) days after the
exchange of the sealed envelopes, the third arbitrator shall be selected by the
parties themselves if they can agree thereon within a further period of 10 days.
If the parties do not so agree, then either party, on behalf of both and on
notice to the other, may request such an appointment by the American Arbitration
Association (or any successor organization) in accordance with its rules then
prevailing or if the American Arbitration Association (or any successor
organization) shall fail to appoint said third arbitrator within fifteen (15)
days after such request is made, then either party may apply for such
appointment, on notice to the other, to the President of the Westchester County
Bar Association (who may consult with the Chairman of the Real Property Law
Committee of the Westchester County Bar Association).  Within ten (10) days
after the appointment of such third arbitrator, the Lessor's arbitrator shall
submit Lessor's Submitted Value to such third arbitrator and the Lessee's
arbitrator shall submit Lessee's Submitted Value to such third arbitrator.  Such
third arbitrator shall, within thirty (30) days after the end of such fifteen
(15) day period, make his own determination of the fair market rent of the
Demised Premises using the criteria set forth in Section 30.04.A. hereof, and
send copies of his determination promptly to both Lessor and Lessee specifying
whether Lessor's Submitted Value or Lessee's Submitted Value was closer to the
determination by such third arbitrator of the fair market rent of the Demised
Premises.  Whichever of Lessor's Submitted Value or Lessee's Submitted Value
shall be closer to the determination by such third arbitrator shall conclusively
be deemed to be the fair market rent of the Demised Premises.

     (3) In no event shall the arbitrators enlarge upon, or alter or amend, this
Lease or Lessor's or Lessee's rights as provided in this Lease, it being
understood that the sole issue for determination by the arbitrators shall be the
single issue of fact of the annual fair rental value of the Demised Premises as
provided in paragraph A of this Section 30.01.

     (4) Except as otherwise provided in the following sentence, the fees and
expenses of an arbitration proceeding shall be borne by the parties equally.
The fees of respective counsel engaged by the parties the fees and expenses of
expert witnesses and other witnesses called and the cost of transcripts shall be
borne by the parties engaging such counsel or, calling such witness or ordering
such transcripts.

     SECTION 30.05. The rights provided to Lessee to extend this Lease as
provided in Section 30.01 is conditioned in all respects upon (i) there being no
Event of Default in the observance or performance of any term, covenant,
condition or agreement of Lessee's part to be observed or performed under this
Lease both at the time the notice of exercise is given and immediately prior to
commencement of the Renewal Term, and (ii) there being no sublease in effect
(other than subleases with related corporations) with respect to the Demised
Premises or any part thereof during the two (2) year period immediately
preceding the Expiration Date originally provided for herein.  Any termination,
cancellation or surrender of this Lease shall terminate any right of extension
hereunder for the Renewal Term.

                     ARTICLE 31 -   FIBER OPTIC NETWORK SERVICES

     SECTION 31.01. From and after the Commencement Date, Lessor agrees that
Lessee shall have the right, subject to the rights of other lessees, and
Lessor's reasonable consent, which shall not be unreasonably withheld,
conditioned or delayed, to install, maintain, repair, remove and operate in the
Demised Premises and penetrate the Building in a location reasonably designated
by Lessor and utilize existing Building conduits and risers for the installation
and maintenance of fiber optic cables, PROVIDED, HOWEVER, that such fiber optic
cables do not exceed four (4) inches in diameter, in connection with Lessee's
fiber optic network (the "Fiber Optic Network") for the Term of this Lease or
any Renewal Term.  Lessee shall notify Lessor of its intention to install, use
and maintain the Fiber Optic Network in accordance with the provisions of this
Lease.

     SECTION 31.02. If Lessor shall grant its consent to the installation, use
or maintenance of the Fiber Optic Network, then the same shall (i) be installed
and maintained at the sole cost and expense of Lessee, (ii) be installed and
maintained in a good and workmanlike manner, in a location reasonably designated
by Lessor, and in compliance with all applicable Legal Requirements (including
existing zoning requirements), Insurance Requirements and Environmental Laws,
(iii) be consistent with the use of the Demised Premises provided for herein,
(iv) be performed in accordance with plans and specifications approved prior to
the commencement of any work by the appropriate Governmental Authorities and by
Lessor, which approval by Lessor will not be unreasonably withheld, conditioned
or delayed, (v) be of such nature so as not to lessen the fair market value of
the Building or Property, and (vi) be performed under the supervision of a
licensed architect reasonably approved by Lessor and in accordance
                                    Page 32 of 40
<PAGE>

with Lessor's STANDARD REQUIREMENTS FOR ALTERATIONS TO BE PERFORMED BY LESSEES,
as may be reasonably amended from time to time.

     SECTION 31.03.A. Unless Lessor shall otherwise expressly indicate in
writing at the time of granting its consent to the installation of the Fiber
Optic Network, Lessee shall, on or before the expiration or sooner termination
of this Lease as and when provided in Section 29.02, remove the Fiber Optic
Network and restore the affected portion of the Demised Premises and Building to
the state or condition thereof existing prior to the installation of the Fiber
Optic Network.

     B. Any and all contractors to be involved in performing work shall be
subject to Lessor's prior approval, which shall not be unreasonably withheld,
conditioned or delayed.

     C. Prior to installing the Fiber Optic Network, Lessee shall furnish Lessor
with evidence reasonably satisfactory to Lessor of such insurance as Lessor may
require and such insurance shall be in full force and effect during such
installation and will cover, by endorsement or otherwise, the risk during the
course of such installation.

     SECTION 31.04. All of the terms, covenants and conditions of this Lease
shall continue in full force and effect.

     SECTION 31.05. The right of Lessee to install, use or maintain the Fiber
Optic Network as provided in Section 31.01 is conditioned in all respects upon
there being no material Event of Default in the observance or performance of any
term, covenant, condition or agreement on Lessee's part to be observed or
performed under this Lease both at the time the notice is given.  Any
termination, cancellation or surrender of this Lease shall terminate Lessee's
right to install, use or maintain the Fiber Optic Network.

                                 ARTICLE 32 - BROKERS

     SECTION 32.01. The parties represent that in connection with this Lease it
dealt with no broker other than Austin Corporate Properties, Inc. and
Insignia/ESG (the "Brokers"), nor has either party had any correspondence or
other communication in connection with this Lease with any other person who is a
broker, and that so far as the parties are aware the Brokers are the only
brokers who negotiated this Lease.  Each party hereby indemnifies the other
party and holds it harmless from any and all loss, cost, liability, claim,
damage, or expense (including court costs and attorneys' fees) arising out of
any inaccuracy of the above representation.  Lessor agrees to pay the Brokers
all commissions due for their services pursuant to a separate written agreement.

                            ARTICLE 33 - SECURITY DEPOSIT

     SECTION 33.01.A. Lessee shall deposit with Lessor, upon execution of this
Lease, the sum of One Hundred and Thirty-Six Thousand, Eight Hundred and Four
and 00/100 ($136,804.00) Dollars either in cash or by Letter of Credit as
provided in Section 33.02 as security for the faithful performance and
observance by Lessee of the terms, provisions, conditions and covenants of this
Lease (the "Security Deposit").  Lessee agrees that, in the event that Lessee
defaults, beyond all applicable grace and cure periods after notice, in respect
of any terms, provisions, conditions and covenants of this Lease (including the
payment of Rent), Lessor may use, apply or retain the whole or any part of the
cash security so deposited or may notify the Issuing Bank (as such term is
defined in Section 33.02) and thereupon receive all of the monies represented by
the said Letter of Credit and use, apply, or retain the whole or any part of
such proceeds, as the case may be, to the extent required for the payment of
Rent, or any other sums as to which Lessee is in default, or for any sum that
Lessor may expend or may be required to expend by reason of Lessee's default, in
respect of the terms, provisions, conditions and covenants of this Lease
(including any damages or deficiency accrued before or after summary proceedings
or other re-entry by Lessor).  In the event that Lessor applies or retains any
portion or all of such cash security or proceeds of such Letter of Credit, as
the case may be, Lessee shall forthwith restore the amount so retained or
applied.

     B. In the event that the Security Deposit hereunder is in cash, Lessor
agrees to maintain such cash in an interest bearing account with the interest to
be added as additional security, except that Lessor shall be entitled to an
administrative fee of One (1%) percent per annum to administer the account.

     amount of the Letter of Credit upon presentation of only the Letter of
     Credit, a sight draft in the amount to be drawn and an affidavit of
     default;

          B. the Letter of Credit shall be deemed to be automatically renewed,
     without amendment, for consecutive periods of one year during the Term of
     this Lease, unless the Issuing Bank sends written notice ("Non-Renewal
     Notice") to Lessor by certified or registered mail, return receipt
     requested, not less than thirty (30) days next preceding the then
     expiration date of the Letter of Credit that it elects not to renew such
     Letter of Credit;

          C. Lessor, after receipt of the Non-Renewal Notice, shall have the
     right, exercisable by a sight draft only, to receive the moneys represented
     by the Letter of Credit (which moneys shall be held by Lessor as a cash
     deposit pursuant to the terms of this Article 33 pending replacement of
     such Letter of Credit); and

          D. Upon Lessor's sale of the Property, or Lessor's interest therein,
     or a leasing of the Property, the Letter of Credit shall be transferable by
     Lessor as provided in Section 33.04.

     SECTION 33.03. In the event of a sale of the Property, or Lessor's interest
therein, or of a leasing of the Property, Lessor shall transfer the cash
security or Letter of Credit, as the case may be, deposited hereunder to the
vendee or lessee, and Lessor shall thereupon be released by Lessee from all
liability for the return of such cash security or Letter of Credit to a new
lessor, provided that such new lessor assumes all of Lessor's obligations with
respect to such cash security or Letter of Credit.  Lessee shall execute such
documents as may be necessary to accomplish such transfer or assignment of the
Letter of Credit.

     SECTION 33.04. Lessee covenants that it will not assign or encumber, or
attempt to assign or encumber the monies or Letter of Credit deposited hereunder
as security, and that neither Lessor nor its successors and/or assigns shall be
bound by any such assignment, or attempted encumbrance.

     SECTION 33.05. In the event that Lessee shall fully and faithfully comply
with all of the terms, provisions, conditions and covenants of this Lease, and
provided further, that no Event of Default shall have occurred and be
continuing, the Security Deposit shall be returned to Lessee within thirty (30)
days after Lessee delivers possession of the Demised Premises to Lessor as
provided for in this Lease.

                               ARTICLE 34 - DEFINITIONS

                              STANDARD REQUIREMENTS FOR
                        ALTERATIONS TO BE PERFORMED BY LESSEES

     For purposes of these STANDARD REQUIREMENTS FOR ALTERATIONS TO BE PERFORMED
BY LESSEES, Lessee's Alterations, as that term is defined in Article 8 of the
Lease, and Lessee's construction, work and alterations as contemplated in
Article 25 of the Lease are hereinafter sometimes collectively referred to as
the "Alterations."  Whenever in this Exhibit G Lessor's approval or consent must
be sought and obtained prior to the performance of any Alterations, such
approval or consent shall not be unreasonably withheld or delayed.

     SECTION 1.  All Lessee's Alterations shall be performed in accordance with
all Governmental Authority, Legal Requirements, Insurance Requirements and
Environmental Laws (as those terms are defined in the Lease) and other agencies
having jurisdiction and with the over-all design and construction standards of
the Building, Building Equipment and Demised Premises.  All Lessee's Alterations
shall be built in accordance with the provisions hereof, the Lease, and the
Final Plans (as hereinafter defined).

     SECTION 2.  All architectural and engineering plans and specifications for
the Demised Premises shall be prepared by a licensed architect employed by
Lessee at its sole cost and expense and shall describe all the work which under
this Lease is to be performed by Lessee and showing in sufficient detail the
location of all utilities, partitions, bathrooms, offices, storage and/or locker
facilities and any other matters which may affect the construction work to be

available plans and specifications for the Building and Building Equipment, if
requested by Lessee or his architect and the actual cost thereof shall be born
by Lessee.

     SECTION 3.  It shall be the sole responsibility of Lessee and/or Lessee's
agent to file all drawings, plans and specifications, pay all fees and obtain
all permits and applications from all Governmental Authority having
jurisdiction, and to obtain a Certificate of Occupancy, Certificate of
Compliance and all other "sign offs" and approvals required to enable Lessee to
occupy the Demised Premises for the purposes provided for in its Lease.  Lessor,
at its sole cost and expense, shall be responsible for all violations in other
parts of the Building which prevent Lessee from obtaining the Certificate of
Occupancy, Certificate of Compliance and all other "sign offs" and approval to
enable Lessee to occupy the Demised Premises

     SECTION 4.  Simultaneously with any request for consent to make Lessee's
Alterations as defined in Article 8 of the Lease or alterations to the Demised

expense shall cause Lessee's architect to prepare and deliver to Lessor for
Lessor's approval two (2) sets of preliminary plans for Lessee's Alterations,
prepared in strict accordance with the provisions contained herein, initialed by
Lessee.  Lessor shall notify Lessee of the matters, if any, in which the
preliminary plans fail to conform to the standards established for the Property,
Building, Building Equipment and/or Demised Premises, or otherwise fail to meet
with the Lessor's approval.  Lessee shall promptly upon receipt of any such
notice or notices from Lessor cause the preliminary plans to be revised in such
manner as is requisite to obtaining Lessor's approval and shall resubmit said
revised preliminary plans initialed by Lessee as aforesaid for Lessor's approval
within Thirty (30) days of said notice.  When Lessor shall determine that the
preliminary plans are satisfactory to Lessor, Lessor shall cause one set thereof
to be initialed on behalf of Lessor, thereby evidencing the approval thereof by
the Lessor, and shall return such set so initialed to Lessee.  The preliminary
plans or revised preliminary plans, as the case may be, so approved by Lessor
are hereinafter referred to as the "Preliminary Plans."  If such Preliminary
Plans are not approved by Lessor within Fifteen (15) days after submission to
Lessor, Lessor shall advise Lessee of such disapproval and Lessee's architect
shall revise said plans at Lessee's cost and expense, and such plans shall be
deemed approved by both Lessee and Lessor.

     SECTION 5.  Within Thirty (30) days after Lessor's approval of Lessee's
Preliminary Plans, Lessee, at its sole cost and expense, shall cause to be
prepared and delivered to Lessor four (4) complete sets of drawings and
specifications showing Lessee's Alterations, prepared in conformity with
Preliminary Plans, and such drawings and specifications shall have been
initialed by Lessee, evidencing Lessee's approval thereof.  Lessor shall notify
Lessee of the matters, if any, in which said drawings and specifications fail to

in such manner as is requisite to obtaining Lessor's approval and shall resubmit
revised drawings and specifications initialed by Lessee as aforesaid for

determine that the drawings and specifications or revised drawings and
specifications, as the case may be, conform to the Preliminary Plans and are
satisfactory to Lessor, Lessor shall cause the plans and specifications to be
initialed on behalf of Lessor, thereby evidencing the approval thereof by
Lessor, and shall return two (2)

thereof, upon notice from Licensor, Licensee shall resist such action or
proceeding at Licensee's expense by counsel selected by Licensee and reasonably
satisfactory to Licensor.

     SECTION 8.01.  In the event Licensee ceases to be a tenant or occupant of

the Property.

Section 2 hereof is based on the current monthly rate of Seventy-Five ($75.00)
Dollars for each reserved space and Sixty-Five ($65.00) Dollars for each
non-reserved space.  Licensee agrees that such rates may, from time to time, be
increased by Licensor, with not less than thirty (30) days prior written notice

for the monthly rental of parking spaces as determined by comparison to similar
