sentence if Tenant is obligated to make such repairs pursuant the provisions of
Article FIFTH (A) hereof. Notwithstanding the foregoing provisions of this
Section, Owner shall have no obligation to make any repairs unless and until
specific actual notice of the necessity therefor shall have been given to Owner.

                             (C) Owner agrees solely to the extent that
non-compliance by Owner prevents Tenant from using or materially interferes with
Tenant's use of the Demised Premises for its normal business operations Owner,

the Real Property, which shall impose any duty upon Owner or Tenant with respect
to the Demised Premises or the use or occupation thereof, or any public portion
of the Building which affects Tenant's use of the Demised Premises and with
which Tenant is not required to comply pursuant to the provisions of Article
ELEVENTH, provided, however, Owner shall not be required to so comply unless and
until Owner shall have received notice of the necessity therefor from Tenant.

               SIXTH: Utilities and Services: (A) Electricity. (1) Owner at
Tenant's expense, shall redistribute or furnish electrical energy to or for the
use of Tenant in the Demised Premises for the operation of the lighting fixtures

character of electrical service is changed by the corporation(s) and/or other
entity(ies) selected by Owner to supply electrical service to the Building or is
no longer available or suitable for Tenant's requirements, no such change,
unavailability or unsuitability shall constitute an actual or constructive
eviction, in whole or in part, or entitle Tenant to any abatement or diminution
of any rent or sums due Owner from Tenant under this Lease, or relieve Tenant
from any of its obligations under this Lease, or impose any liability upon
Owner, or its agents, by reason of inconvenience or annoyance to Tenant, or
injury to or interruption of Tenant's business or otherwise unless such change,
unavailability or unsuitability is caused by Owner's gross negligence or willful
minconduct. Tenant covenants that at no time shall the use of the electrical
energy in the Demised Premises exceed the capacity of the existing feeders or
risers or wiring installations then serving the Demised Premises.

                                            (3)    Owner  shall  provide for an
electrical  load of six (6) watts per square foot of usable area demand load
other than during any period it is prohibited from doing so by any laws, orders,
rules and/or regulations of any applicable governmental authorities (including,
but not limited to, the New York State Energy Conversation Construction Code) in
which event the reference to six (6) watts hereinabove set forth shall, during
such period, be decreased to the maximum number of watts per usable square foot
which is permitted by any such laws, orders, rules and/or regulations. The
foregoing shall be exclusive of the electrical power for the Building HVAC

reasonable judgment, such additional feeders or risers are necessary and are
permissible under applicable laws and insurance regulations and the installation
of such feeders or riders will not cause permanent damage or injury to the

                                       9
<PAGE>

Building or the Demised Premises or cause or create a dangerous or hazardous
condition or entail excessive or unreasonable alterations or repairs to or

in Owner's reasonable judgment; and (ii) mechanical ventilation through the
Building air conditioning system on business days from 8:00 A.M. to 7:00 P.M.,
except when conditioned air or heat is being furnished, to the extent required
pursuant to law. Notwithstanding the foregoing provisions of this paragraph (D),
Owner shall not be responsible if the normal operation of the Building air
conditioning system shall fail to provide conditioned air at reasonable
temperatures, pressures or degrees of humidity or in reasonable volumes or
velocities in any portions of the Demised Premises (a) which, by reason of any

claiming through or under Tenant, shall have an electrical load in excess of
four (4) watts per square foot of usable area for all purposes (including
lighting and power), or which shall have a human occupancy factor in excess of
one person per one hundred seventy-five (175) square feet of usable area (the
average electrical load and human occupancy factors for which the Building air
conditioning system is designed) or (b) because of any rearrangement of
partitioning or other Alterations made or performed by or on behalf of Tenant or
any person claiming through or under Tenant. Whenever said air conditioning
system is in operation, Tenant agrees to cause all the windows in the Demised
Premises to be kept closed and to cause the Venetian blinds in the Demised
Premises to be kept closed if necessary because of the position of the sun.
Tenant agrees to cause all the windows in the Demised Premises to be closed
whenever the Demised Premises are not occupied. Tenant shall cooperate fully

air conditioning and ventilating system. Tenant agrees that if its violation or
breach of any of the foregoing provisions of this paragraph (D), shall adversely
affect the operation of the Building's heating, ventilation and air-conditioning
system, no such adverse affects shall constitute an actual or constructive

                                       10
<PAGE>

eviction, in whole or in part, or entitle Tenant to any abatement or diminution
of rent, or relieve Tenant from any of its obligations under this Lease, or
impose any liability upon Owner, or its agents, by reason of inconvenience or
annoyance to Tenant, or injury to or interruption of Tenant's business or
otherwise.

Building and shall comply with all reasonable rules and regulations of Owner
with respect thereto. Tenant, at Tenant's expense, shall cause all portions of
the Demised Premises used for the storage, preparation, service or consumption
of food or beverages to be cleaned daily in a manner satisfactory to Owner, and
to be exterminated against infestation by vermin, roaches or rodents
(collectively, "Infestation") regularly and, in addition, whenever there shall
be evidence of any infestation.

                                            (2) Owner, at Owner's expense, shall
clean the public portions of the Building at regular intervals and cart Tenant's
ordinary refuse and rubbish in accordance with practices and standards adopted
by Owner for the Building and Owner, at Owner's expense, shall perform or cause
to perform extermination services against Infestation of the public areas as and
when required, in Owner's reasonable judgment.

                                            (3) The removal of refuse and
rubbish and the furnishing of office cleaning services to Tenant by persons
other than Owner and its contractors shall be performed in accordance with such
regulations and requirements as, in Owner's reasonable judgment, are necessary
for the proper operation of the Building, and Tenant agrees that Tenant will not
permit any person to enter the Demised Premises or the Building for such
purposes, or for the purpose of providing extermination services required to be
performed by Tenant pursuant to Subsection A of this Section, other than persons
first approved by Owner, such approval not unreasonably to be withheld.

                             (F) (1) If Tenant, in Owner's reasonable judgment,
uses water for more than ordinary lavatory purposes, Owner may install a hot
water meter and a cold water meter and thereby measure Tenant's consumption of
water for all purposes. Owner shall pay for the cost of any such meters and
their installation, and Tenant shall keep any such meters and any such
installation equipment in good working order and repair, at Tenant's cost and
expense. Tenant agrees to pay for water consumed as shown on said meters, and
sewer charges, taxes and any other governmental charges thereon, as and when
bills are rendered. For the purposes of determining the amount of any sums
required to be paid by Tenant under this Section, all hot and cold water
consumed during any period when said meters are not in good working order shall
be deemed to have been consumed at the rate of consumption of such water during
the most comparable period when such meters were in good working order.

                                    (2) In connection with Owner's Initial
Construction, Owner shall, at Tenant's expense, supply and install a hot water

                             (G) The Fixed Rent does not reflect or include any
charge to Tenant for the furnishing or distributing of any necessary elevator
facilities, heat, conditioned air or mechanical ventilation to the Demised
Premises during periods (referred to as "Overtime Periods") other than the hours
and days set forth above in this Article for the furnishing and distributing of
such services. Accordingly, if Owner shall furnish any such elevator facilities,
heat, conditioned air or mechanical ventilation to the Demised Premises at the
request of Tenant during Overtime Periods, Tenant shall pay Owner for such
services at the standard reasonable rates then fixed by Owner for the Building
or, if no such rates are then fixed, at reasonable rates. Owner shall not be
required to furnish any such services during Overtime Periods, unless Owner has
received reasonable advance notice from Tenant requesting such services. If
Tenant fails to give Owner reasonable advance notice requesting such services
during any Overtime Periods, then, whether or not the Demised Premises are
habitable during such Overtime Periods, failure by Owner to furnish or
distribute any such services during such Overtime Periods shall not constitute
an actual or constructive eviction, in whole or in part, or entitle Tenant to
any abatement or diminution of rent, or relieve Tenant from any of its
obligations under this Lease, or impose any liability upon Owner or its agents
by reason of inconvenience or annoyance to Tenant, or injury to or interruption
of Tenant's business or otherwise.

                             (H) Owner's Right to Stop Service: Owner reserves
the right to stop the service of the heating, air conditioning, ventilating,
elevator, plumbing, electrical, communications or other mechanical systems or
facilities in the Building when necessary by reason of accident or emergency, or
for repairs, alterations, replacements or improvements, which, in the judgment
of Owner are desirable or necessary, until said repairs, alterations,
replacements or improvements shall have been completed. The exercise of such
right by Owner shall not constitute an actual or constructive eviction, in whole
or in part, or entitle Tenant to any abatement or diminution of rent, or relieve
Tenant from any of its obligations under this Lease, or impose any liability
upon Owner or its agents by reason of inconvenience or annoyance to Tenant, or
injury to or interruption of Tenant's business, or otherwise. Owner shall employ
reasonable diligence in attempting to restore the operation of any such systems
or facilities without any obligation, however, to employ labor at overtime or
other premium pay rates.

an "V" on said Exhibit "2" must remain where shown on said Exhibit "2". Owner
shall have the right to reconfigure the Parking Lot (including the exclusive
spaces) and add additional buildings in the Parking Lot and may increase or
reduce the number of spaces in the Parking Lot, so long as any such
reconfiguration, and/or additional buildings do not diminish Tenant's rights to
the parking spaces Tenant is otherwise entitled to hereunder. No such

                                       12
<PAGE>

reconfiguration, additional buildings or reduction in the number of space in the
Parking Lot for any reason, including, but not limited to, the construction of
additional buildings therein or any acquisition or condemnation set forth in
Article TWELFTH, shall constitute an actual or constructive eviction, in whole
or in part, or entitle Tenant to any abatement or diminution of rent or relieve
Tenant from any of its obligations under this Lease or impose any liability upon
Owner, it agents, or upon any lessor under any ground or underlying lease, or
upon the holder of any mortgage. Tenant shall have no rights in and to the
Parking Lot other than the aforedescribed exclusive use and nonexclusive use, in
common with other tenants and occupants and their business visitors, for Tenant

Premises upon the Expiration Date broom clean and in good order and in the same
condition that the Demised Premises existed on the Commencement Date, ordinary

property and effects of Tenant or such person which shall remain in the Demised
Premises after the Expiration Date and any net proceeds from the sale thereof,
without waiving any of Owner's rights with respect to any "Event of Default" (as
hereinafter defined) by Tenant. Tenant hereby expressly waives for itself and
for any person claiming through or under Tenant any rights which Tenant or any
such person may have under the provisions of Section 2201 of the New York Civil
Practice Law and Rules or any successor law of like import then in force in
connection with any holdover summary proceedings which Owner may institute to
enforce the foregoing provisions of this Article EIGHTH. If the date upon which

Article EIGHTH shall survive the Expiration Date.

               NINTH: Assignment and Subletting. (1) Tenant may not assign or
transfer this Lease, without the prior written consent of Owner in each
instance, which consent Owner may withhold in its sole discretion. The sale,
pledge, transfer or other alienation of (a) any of the issued and outstanding
capital stock of any corporate Tenant (unless such stock is publicly traded on a

                                       13
<PAGE>

recognized security exchange or over-the counter market) or (b) any interest in
any partnership or joint venture of Tenant, however accomplished, and whether in
a single transaction or in a series of related and/or unrelated transactions,
resulting in a change of more than forty-nine (49%) percent of the then issued
and outstanding capital stock of any corporate Tenant (unless such stock is
publicly traded on a recognized security exchange or over-the-counter market) or
the interests in any partnership or joint venture of Tenant, however
accomplished, and whether in a single transaction or in a series of
related/unrelated transactions, shall be deemed, for the purposes of this
Article NINTH, as an assignment of this Lease which shall require the prior
consent of Owner in each instance. Tenant shall not be permitted to sublet the
Demised Premises without the prior written consent of Owner which consent Owner
may withhold at its sole discretion.

                                            (2) As long as Tenant is not in
default under any of the terms, covenants or conditions of this Lease on
Tenant's part to be observed and performed beyond applicable notice and cure
periods, Tenant shall have the right without the prior consent of Owner, to
permit the use or occupancy of all or any part of the Demised Premises by any
subsidiary or affiliate of Tenant named herein for the use permitted in this
Lease only for such period as it shall remain such subsidiary or affiliate. For
the purposes of this Article: (a) a "subsidiary" of Tenant named herein shall
mean any corporation not less than fifty-one (51%) percent of whose outstanding
voting stock at the time shall be owned by Tenant named herein, and (b) an
"affiliate" of Tenant named herein shall mean any corporation, partnership or
other business entity which controls or is controlled by, or is under common
control with Tenant named herein. For the purpose of the definition of
"affiliate" the word "control" (including, "controlled by" and "under common
control with") as used with respect to any corporation, partnership or other
business entity, shall mean the possession of the power to direct or cause the
direction of the management and policies of such corporation, partnership or
other business entity, whether through the ownership of voting securities or
contract. However, no such use and occupancy shall be valid unless, Tenant shall
give prompt notice to Owner of any such use or occupancy of all or any part of
the Demised Premises and such use or occupancy shall be subject and subordinate
to all of the terms, covenants and conditions of this Lease. No such use or
occupancy shall operate to vest in the user or occupant any right or interest
in this Lease or the Demised Premises.

                                            (3)    Reasonable Approval of
Assignment or Subletting:  (a) Notwithstanding the foregoing provisions hereof,
Tenant will neither assign this Lease in whole or in part nor sublease all or
part of the Demised Premises without Owner's prior written consent, which Owner
agrees will not be unreasonably withheld or delayed as hereinafter set forth.

                                    (b)    If Tenant  requests  Owner's consent
to any assignment or sublease, Tenant will promptly provide Owner with (i) the
name and address of the proposed assignee or subtenant, (ii) a copy of the
proposed assignment or sublease, (iii) reasonably satisfactory information about
the nature, business and business history of the proposed assignee or subtenant,
and (iv) banking, financial or other credit information, and references about
the proposed assignee or subtenant sufficient to enable Owner to determine the
financial responsibility and character of the proposed assignee or subtenant. If
all of the foregoing meets with Owner's approval, which approval shall not be
unreasonably withheld or delayed, Owner shall consent to any such proposed
assignment or subletting.

                                       14
<PAGE>

                                          (c) Owner's consent to any assignment
or sublease will not waive the requirement of its consent to any subsequent
assignment or sublease.
                                    (d)    Owner's  consent  to  an  assignment
or sublease will not be effective until: a fully executed copy of the instrument
of assignment or sublease has been delivered to the Owner; in the case of an
assignment, the owner has received a written instrument in which the assignee
has assumed and agreed to perform all of the Tenant's obligations in the Lease;
and Owner has received reimbursement for its reasonable attorneys' fees and
costs incurred in connection with both determining whether to give its consent
and giving its consent.

                                      (e) Owner's consent to an assignment
or sublease will not release the Tenant from the payment and performance of its
obligations in the Lease, but rather the Tenant and its assignee will be jointly
and severally primarily liable for such payment and performance. An assignment
or sublease without Owner's prior written consent will be void at Owner's
option.

               TENTH: Owner Access. (A) (1) Owner and its agents shall have the
following rights in and about the Demised Premises: (i) to enter the Demised
Premises at all times to examine the Demised Premises or for any of the purposes
set forth in this Article TENTH or for the purpose of performing any obligation
of Owner under this Lease or exercising any right or remedy reserved to Owner in
this Lease, or complying with any Legal Requirement which Owner is obligated to
comply with hereunder, and if Tenant, its officers, partners, agents or

to take all materials into and upon the Demised Premises that may be required in
connection with any such decorations, repairs, alterations, improvements,
additions or maintenance; and (vi) to alter, renovate and decorate the Demised
Premises at any time during the Demised Term if Tenant shall have removed all or
substantially all of Tenant's property from the Demised Premises. The lessors
under any superior lease and the holders of any mortgage shall have the right to
enter the Demised Premises from time to time through their respective employees,
agents, representatives and architects to inspect the same or to cure any
default of Owner or Tenant relating thereto. Owner shall have the right, from
time to time, to change the name, number or designation by which the Building is
commonly known which right shall include, without limitation, the right to name
the Building after any tenant of the Building.

                                            (2) Supplementing the provisions of
this Paragraph A, Owner, agrees that, except in cases of emergency, any entry
upon the Demised Premises shall be made at reasonable times, and only after
reasonable advance notice (which may be mailed, delivered or left at the Demised
Premises, notwithstanding any contrary provisions of this Lease), and any work

                                       15
<PAGE>

performed or installations made by Owner shall be made with reasonable diligence
and any such entry, work or installations shall be made in a manner designed to
minimize interference with Tenant's normal business operations (however, nothing
contained in this Section shall be deemed to impose upon Owner any obligation to
employ contractors or labor at so-called overtime or other premium pay rates).

                             (B) Owner's Reservation of Rights to Portions of
the Building: All parts
(except surfaces facing the interior of the Demised Premises) of all walls,
windows and doors bounding the Demised Premises (including exterior Building
walls, core corridor walls, doors and entrances), all balconies, terraces and

Premises used for shafts, stacks, stairways, chutes, pipes, conduits, ducts, fan
rooms, heating, air conditioning, ventilating, plumbing, electrical,
telecommunication and other mechanical facilities, closets, service closets and
other Building facilities, and the use thereof, as well as access thereto

alteration and repair, are hereby reserved to Owner. Owner also reserves the
right at any time to change the arrangement or location of entrances,
passageways, doors, doorways, corridors, elevators, stairs, toilets and other
public parts of the Building, provided any such change does not permanently and
unreasonably obstruct Tenant's access to the Demised Premises. Nothing contained
in this Article TENTH shall impose any obligation upon Owner with respect to the
operation, maintenance, alteration or repair of the Demised Premises or the
Building.

                             (C) Access to Third Parties: Owner and its agents
shall have the right
to permit access to the Demised Premises, whether or not Tenant shall be

entitled to, such access for the purpose of taking possession of, or removing,
any property of Tenant or any other occupant of the Demised Premises, or for any
other lawful purpose, or by any representative of the fire, police, building,
sanitation or other department of the City, State or Federal Governments.
Neither anything contained in this Article TENTH, nor any action taken by Owner
under this Paragraph (C), shall be deemed to constitute recognition by Owner
that any person other than Tenant has any right or interest in this Lease or the
Demised Premises.

                             (D) No Actual or Constructive Eviction: The
exercise by Owner or its
agents or by the lessor under any superior lease or by the holder of any
mortgage of any right reserved to Owner in this Article TENTH shall not
constitute an actual or constructive eviction, in whole or in part, or entitle
Tenant to any abatement or diminution of rent, or relieve Tenant from any of its
obligations under this Lease, or impose any liability upon Owner, or its agents,
or upon any lessor under any superior lease or upon the holder of any such
mortgage, by reason of inconvenience or annoyance to Tenant, or injury to or
interruption of Tenant's business, or otherwise.

                             (E) Whenever reasonably possible, any entry by
Owner (or its agents) to the Demised Premises shall be with a designated agent
or representative of Tenant.

               ELEVENTH: Legal Compliance: (A) Tenant agrees that its use of the
Demised Premises and the installation, operation and maintenance of Tenant's
personal property and equipment shall at all times, at Tenant's expense,

                                       16
<PAGE>

strictly comply with all applicable "Legal Requirements", and the orders and
requirements of all "Government Authorities". The term "Legal Requirements"
shall mean all present and future laws, codes, ordinances, statutes,
requirements, orders and regulations, ordinary and extraordinary, foreseen and
unforeseen, of any Governmental Authority (hereinafter defined) and all
directions, requirements, orders and notices of violations thereof. The term
"Governmental Authority" shall mean the United States of America, the State of
New York, the County of Suffolk, Town of Islip, any political subdivision
thereof and any agency, department, commission, board, bureau or instrumentality
of any of the foregoing, now existing or hereafter created, having jurisdiction
over Owner, Tenant, the use of the Demised Premises or the Building.

                             (B) In addition to the aforesaid, Tenant shall (i)
not generate, store,
install, dispose of or otherwise handle any substance, waste or material which
is deemed hazardous, toxic, a pollutant or contaminant, under any Legal
Requirement now or hereinafter in effect (referred to herein as "Hazardous
Substances") in the Demised Premises, or in or around the Building, in any
manner contrary to any applicable Legal Requirements; (ii) not install or place
in the Demised Premises any asbestos or asbestos-containing materials (iii) at
Tenant's cost and expense remove, clean-up and remedy any Hazardous Substance in
the Demised Premises or the Building to the extent and in the manner required by
any applicable Legal Requirements, if the presence of such Hazardous Substances
resulted from the action or inaction of Tenant, its employees, contractors,
subcontractors, agents, occupants or invitees. Tenant shall not remove, clean
up, abate, or disturb any asbestos or asbestos-containing material in or about
the Demised Premises except as Owner shall direct.

                             (C) Owner's Obligations - Asbestos (i) In the event
that, at any time during the Demised Term, in connection with any Alterations
proposed to be performed by Tenant in the Demised Premises Tenant is unable to
obtain a form signed by a certified asbestos investigator, or any other form or
approval required by Federal, State, County or Municipal authorities, indicating
that said Alterations do not constitute an asbestos project, Owner agrees, upon
notice from Tenant to such effect, to perform such work as shall be required to
abate or remove any asbestos in the Demised Premises in order to enable Tenant
to obtain any such form or approval.

                                      (ii) If any laws, orders, rules or
regulations of any Federal, State, County or Municipal authority require that
any asbestos or other hazardous material contained in or about the Demised
Premises be removed or dealt with in any particular manner, or, in the event any
work performed by Owner in connection with any removal or abatement or other
work performed in connection with the existence of any such asbestos or other
hazardous material is disturbed or damaged by Tenant or any person claiming
through or under Tenant, then it shall be Owner's obligation, at Owner's
expense, to remove, abate, or otherwise deal with such asbestos or other
hazardous material in accordance with such laws, orders, rules and regulations.

                                       iii. Notwithstanding the provisions of
subsections (i) and (ii) of this Section, in the event any asbestos or other
hazardous material is installed in the Demised Premises by or on behalf of

                                       17
<PAGE>

Tenant, or any person claiming through or under Tenant, Owner shall have no
responsibility in connection with the asbestos or other hazardous material so
installed by Tenant or any person claiming through or under Tenant and no
obligation to perform any work with respect to the asbestos or other hazardous
material so installed by Tenant or any person claiming through or under Tenant,
but it shall be Tenant's obligation, at Tenant's expense, to (i) perform such
work with respect to such asbestos or other hazardous material so installed by
Tenant or any person claiming through or under Tenant as shall be required to
abate or remove any asbestos in the Demised Premises in order to enable Tenant
to obtain any form or approval referred to in subsection (i), and (ii) remove,
abate or otherwise deal with such asbestos or other hazardous material in
accordance with all such laws, orders, rules and regulations referred to in
subsection (ii).



               TWELFTH: Casualty and Condemnation. (A) In the event that the
Demised Premises shall be damaged by fire or other casualty, Owner shall have no
obligation to repair such damage provided that if Owner gives Tenant notice that
it intends to repair such damage within ninety (90) days of such damage or
casualty then, this Lease shall remain in full force and effect provided that
Owner shall undertake such repairs with reasonable diligence. If the Tenant
shall be unable to use all or substantially all of the Demised Premises or
Tenant's equipment by reason of a fire or casualty which was not the result of
the act or negligence of Tenant, then, during such period of inability the Fixed
Rent, increases therein or other sums payable by Tenant to Owner shall abate
until the earlier of the date (i) such damage is repaired or (ii) Tenant begins
to use Demised Premises or (iii) this Lease and the Demised Term shall end as
provided in this Article TWELFTH, provided however, that in the event that only
a portion of the Demised Premises is so rendered unusable then, the Fixed Rent
shall be abated in the same portion that the usable portion of the Demised
Premises bears to the total amount of the Demised Premises. In the event that
Owner shall not give notice that it intends to repair such damage, then, Tenant
shall have the option, by notice to Owner within thirty (30) days after the
initial ninety (90) day period, to cancel this Lease and the Demised Term in
which event this Lease and the Demised Term shall terminate and be of no further
force and effect as of the date of such notice and except for those obligations
which survive expiration of the Demised Term, neither party shall have any
further obligation or liability under this Lease for any period after such
effective termination date. In any event, however, if in the event any such fire
or other casualty in the Demised Premises is not substantial in Owner's
reasonable judgment, Owner shall be required to repair any damage caused by such
fire or other casualty in accordance with the applicable provisions of this
Article.

                             (B) Notwithstanding anything contained in this
Lease to the contrary, in the event that any of the following listed events
shall occur (sometimes referred to herein as the "Termination Events"), then
this Lease and the Demised Term shall terminate and be of no further force and
effect as of the effective date that this Lease shall so terminate. For the
purposes hereof the Termination Events shall be any of the following:

                                      (i) if (a) the Demised Premises or (b)
                      the Building shall be damaged by fire or other casualty
                      (whether or not in such instance the Demised Premises
                      shall be so damaged) and Owner has the right hereunder and

                                       18
<PAGE>

                      so elects not to repair or restore such damage in which
                      event the Demised Term shall terminate on a date set forth
                      in a notice by Owner to Tenant, within a reasonable period
                      of time thereafter, terminating this Lease and the Demised
                      Term (i) as of the date of such fire or casualty, if the
                      Demised Premises was damaged thereby, or (ii) a date set
                      forth in Owner's notice;

                                                (ii) the Demised Premises or a
                      substantial part of the Building shall be acquired or
                      condemned by any legal authority or for public use or
                      purpose in which event the Lease granted hereunder shall
                      terminate upon a notice by Owner to Tenant terminating
                      this Lease and the Demised Term as of the date of such
                      taking and Owner shall be entitled to the entire award
                      therefor, except that nothing herein shall prevent Tenant
                      from making any claim for its relocation or moving
                      expenses.

                             (C) (1) Tenant's Subrogation:Tenant acknowledges
that it has been
advised that Owner's insurance policies do not cover Tenant's personal property
or any other property of Tenant in the Demised Premises; accordingly, it shall
be Tenant's obligation to obtain and maintain insurance covering its property in
the Demised Premises. Tenant shall attempt to obtain and maintain, throughout
the Demised Term, in Tenant's casualty and other insurance policies covering
Tenant's personal property and other property of Tenant in the Demised Premises,
so-called "waiver subrogation" provisions to the effect that such policies shall
not be invalidated should the insured waive, in writing, prior to a loss, any or
all right of recovery against any party for loss occasioned by fire or other
casualty. If Tenant is unable to obtain such provisions in Tenant's property and
other insurance policies, Tenant shall name Owner as an additional insured but
not as a loss payee under such policies, it being understood and agreed that
Owner shall have no right whatsoever to any of the proceeds of such insurance.
As long as such or similar provisions are included in such insurance policies
then in force, Tenant hereby waives (and agrees to cause any other permitted
occupants of the Demised Premises to execute and deliver to Owner written
instruments waiving) any right of recovery against Owner, any lessors under any
ground or underlying lease, the holders of any mortgage, and all other tenants
or occupants of the Building, and any servants, employees, agents or contractors
of Owner, or of any such lessor, or holder or any such other tenants or
occupants, for any loss occasioned by fire or other casualty. In the event that
at any time such insurance carriers shall not include such or similar provisions
in any such insurance policy, the waiver set forth in the foregoing sentence (or
in any written instrument executed by any other permitted occupant of the
Demised Premises) shall, upon notice given by Tenant to Owner, be deemed of no
further force or effect from and after the giving of such notice. During any
period while any such waiver of right of recovery is in effect, Tenant, or any
other permitted occupant of the Demised Premises, as the case may be, shall look
solely to the proceeds of such policies to compensate Tenant or such other
permitted occupant for any loss occasioned by fire or other casualty.

                                       19
<PAGE>

                  (2)    Owner's   Subrogation  Waiver  Provisions: Owner shall
attempt to obtain and maintain, through-out the Demised Term, in Owner's fire
and extended coverage insurance policies covering the Building, provisions to
the effect that such policies shall not be invalidated should the insured waive,
in writing, prior to a loss, any or all right of recovery against any party for
loss occur-ring to the Building. In the event that at any time Owner's fire
insurance carriers shall exact an additional premium for the inclusion of such
or similar provisions, Owner shall give Tenant notice thereof. In such event, if
Tenant agrees, in writing, to reimburse Owner for such additional premium for
the remainder of the Demised Term, Owner shall require the inclusion of such or
similar provisions by Owner's fire insurance carriers. As long as such or
similar provisions are included in Owner's fire insurance policies then in
force, Owner hereby waives (i) any obligation on the part of Tenant to make
repairs to the Demised Premises necessitated or occasioned by fire or other
casualty that is an insured risk under such policies, and (ii) any right of
recovery against Tenant, any other permitted occupant of the Demised Premises,
and any of their servants, employees, agents or contractors, for any loss
occasioned by fire or other casualty which is an insured risk under such
policies. In the event that at any time Owner's fire insurance carriers shall
not include such or similar provisions in Owner's fire insurance policies, the
waivers set forth in the foregoing sentence shall, upon notice given by Owner to
Tenant, be deemed of no further force or effect.

                             (D) (i)Supplementing the provisions of (A) and (B)
hereof, in the event (a) the Demised Premises or Building shall be damaged by
fire or other casualty and Tenant shall be unable to use all or a material
portion of the Demised Premises as a result of such damage and (b) Owner shall
not exercise the right to terminate this Lease in accordance with the provisions
of paragraph (A) or (B) hereof, then Owner shall be obligated to repair any such
damage, and, if such damage is not repaired within one hundred eighty (180) days
after the date of such fire or other casualty (such one hundred eighty (180) day
period is referred to as the "Restoration Period"), Tenant shall have the
following options:

                                             (a) to give to Owner within twenty
(20) days next following the expiration of the Restoration Period a ten (10)
days' notice of termination of this Lease, or

                                           (b) to extend the Restoration Period
for a further period of one (1) month by notice given to Owner within twenty
(20) days after the expiration of the initial Restoration Period. In the event
Tenant shall have given such notice to Owner extending the initial Restoration
Period and if such damage shall not have been repaired by Owner within any
extended Restoration Period, Tenant shall have the options to (a) further extend
the Restoration Period for further successive periods of one (1) month, by
notice given to Owner within twenty (20) days after the expiration of any
extended Restoration Period or (b) to give Owner, within twenty (20) days after
the expiration of any such extended Restoration Period of a ten (10) days'
notice of termination of this Lease.

                                 (ii) Notwithstanding anything to the contrary
contained in the provisions of subsection (i) of this Paragraph (D), in the
event that an independent architect shall determine that the repair of such
damage to the Demised Premises or Building will reasonably require a period

                                       20
<PAGE>

longer than one
hundred eighty (180) days Owner shall, within sixty (60) days after the date of
such fire or casualty, give a notice to Tenant extending the initial Restoration
Period to the date upon which Owner estimates that such repair to the Demised
Premises or Building shall be completed. In the event Owner shall give such a
notice under this subsection (ii), then the initial Restoration Period set forth
in subsection (i) of this paragraph (D), shall be so extended and (b) Tenant
shall have the further option to give to Owner a ten (10) days' notice of
termination of this Lease within thirty (30) days next following the giving of
such notice under this subsection (ii) by Owner to Tenant extending the initial
Restoration Period.

                                 (iii) In the event that Tenant shall fail to
give any such notice within the time periods set forth therein, Tenant shall be
deemed to have given to Owner a notice pursuant to subdivision (b) of subsection
(i) of this Paragraph (D) extending the Restoration Period provided, however,
that any ten (10) days' notice of termination given by Tenant pursuant to the
provisions of subsection (ii) of this Paragraph (D) beyond the thirty (30) day
period provided therein shall be void and of no force and effect.

                                 (iv) In the event that Tenant shall give to
Owner with the applicable time periods set forth in the foregoing provisions of
this Section a ten (10) days' notice of termination of this Lease, this Lease
and the Demised Term shall come to an end and expire upon the expiration of
said ten (10) days with the same effect as if the date of the expiration of
said ten (10) days were the Expiration Date, the Fixed Rent and all increases
thereof shall be apportioned as of the casualty date, and any prepaid portion
of Fixed Rent for any period after such date shall be refunded by Owner to
Tenant.

                                 (v) Nothing  contained in the  foregoing
provisions  of this  Paragraph (D) shall be deemed to affect the rights of
Owner to give to Tenant a notice of termination of this Lease in accordance
with the provisions of Paragraph (B) hereof.

               THIRTEENTH: Indemnity and Insurance: (A) Tenant covenants and
agrees to defend, protect, indemnify and hold harmless Owner, Rudin Management
Company, Inc., Cogswell Realty Group, LLC, and CRG Management, LLC (which, as of
the date hereof, is Owner's managing agent), and the agents, servants and
employees of each of the foregoing (individually, "Indemnitee" and collectively
the "Indemnitees") from and against each and every claim, demand, cause of
action, liability, cost, damage, loss, penalty, fine, judgment or expense
(including, but not limited to, attorneys' fees and expenses incurred in defense
of the Indemnitees) which (i) may be made, asserted, brought or recovered by any
person, firm or corporation arising out of any death or bodily or personal
injury (including sickness or disease) or any damage to property to the extent
caused by, resulting from or in any way directly or indirectly incidental to or
in connection with the use of the Demised Premises or the operation of the
Tenant's equipment, and/or any act, omission or negligence of Tenant and its
agents contractors or employees and (ii) shall arise or result from or be
incurred in connection with or in any way be incidental to (1) any breach by
Tenant of its obligations under this Lease or (2) any violation of any Legal
Requirement or any fine, penalty or governmental order issued to or enforced
against Owner or any Indemnitee by any relevant Governmental Authority with
regard to such violation; the term "expense" shall include, but not be limited
to, any attorneys' fees or expenses incurred by Owner in connection with the

                                       21
<PAGE>

aforesaid and attorneys' fees or expenses incurred in connection with any action
to recover such attorneys' fees or expenses. The obligations of Tenant hereunder
shall survive the expiration, cancellation or termination of this Lease and the
Demised Term.

                             (B) Without limiting the aforesaid, Tenant agrees
to be responsible for any damage caused to the Building, and/or any other
property owned by Owner or any tenant, Tenant, user or occupant of the Building
which may be caused by Tenant or any of its agents or representatives.
Throughout the Demised Term and for so long as Tenant (or any person through or
under Tenant) shall use or occupy the Demised Premises, Tenant shall, at
Tenant's cost and expense, obtain and maintain throughout the Demised Term
comprehensive public liability and water legal liability insurance against any
claims by reason of personal injury, death and property damage occurring in or
about the Demised Premises covering, without limitation, the operation of any
private air conditioning equipment and any private elevators, escalators or
conveyors in or serving the Demised Premises or any part thereof, whether
installed by Owner, Tenant or others, and shall furnish to Owner duplicate
original policies of such insurance at least ten (10) days prior to the
Commencement Date and at least ten (10) days prior to the expiration of the term
of any such policy previously furnished by Tenant, in which policies Owner, and
Owner's Indemnitees shall be named as parties insured, which policies shall be
issued by companies, and shall be in form and amounts, satisfactory to Owner.

               FOURTEENTH: Subordination. (A) This Lease and all of Tenant's
rights hereunder shall remain, subject and subordinate in all respects to all
ground or underlying leases now or hereafter in effect and to all mortgages
which may now or hereafter affect such leases and/or the Building and/or the
Real Property, and to all advances made or hereafter to be made under such
mortgages, and to all renewals, modifications, consolidations, correlations,
replacements and extensions of, and substitutions for, such leases and
mortgages. The foregoing provisions of this Article shall be self-operative and
no further instrument of subordination shall be required.

                             (B) Owner agrees within a reasonable time after the
execution and delivery of this Lease to request the then holder or holders of
the existing mortgage to enter into an agreement substantially to the effect
that in the event of any foreclosure of the existing mortgage, such holder or
holders will not make Tenant a party-defendant to such foreclosure (unless
required by law in order to obtain jurisdiction, but in such event, no judgment
foreclosing this Lease will be sought) nor disturb its possession under this
Lease so long as there shall be no default by Tenant under this Lease beyond
applicable grace periods (any such agreement, or any agreement of similar
import, is referred to as a "Non-Disturbance Agreement" and any provisions in
any Mortgage substantially to the same effect as those contained in a
Non-Disturbance Agreement are referred to as "Non-Disturbance Provisions"). If
Owner is unable in good faith to obtain any such Non-Disturbance Agreement or
Non-Disturbance Provisions, neither the validity of this Lease nor the
obligations of Tenant under this Lease shall be affected thereby and Owner shall
not be liable to Tenant for its failure to obtain any such Non-Disturbance
Agreement or Non-Disturbance Provisions, it being intended that Owner's sole
obligation with respect to any Non-Disturbance Agreement or Non-Disturbance
Provisions, shall be to request, in good faith, within a reasonable time after
the execution and delivery of this Lease the then holders of any Mortgage to
enter into such Non-Disturbance Agreement. If required by the holder of any

                                       22
<PAGE>

Mortgage, Tenant shall promptly join in any commercially reasonable
Non-Disturbance Agreement to indicate it concurrence with the provisions
thereof. Tenant will pay any commercially reasonable fee charged by any holder
or lessor for preparing such Agreement.

                             (C) Before Owner executes any future Mortgage,
Owner agrees to request the
then holder or holders of such future Mortgage to enter into a Non-Disturbance
Agreement or include Non-Disturbance Provisions in such future Mortgage. Before
Owner executes any future Superior Lease of the Real Property or the Building,
Owner shall request the lessor thereof to enter into an agreement substantially
to the effect that in the event of the termination of such Superior Lease by
reason of the default or insolvency of the lessee thereunder, such lessor will
permit Tenant to attorn to such lessor and will not disturb its possession under
this Lease so long as there shall be no default by Tenant under this Lease
beyond applicable grace periods (any such agreement, or any agreement of similar
import, is referred to as a "Tenant Recognition Agreement" and any provisions in
any such Superior Lease substantially to the same effect as those contained in a
Tenant Recognition Agreement are referred to as "Tenant Recognition
Provisions"). If Owner is unable in good faith to obtain any such
Non-Disturbance Agreement, Non-Disturbance Provisions, Tenant Recognition
Agreement or Tenant Recognition Provisions, neither the validity of this Lease
nor the obligations of Tenant under this Lease shall be affected thereby and
Owner shall not be liable to Tenant for its failure to obtain any such
Non-Disturbance Agreement, Non-Disturbance Provisions, Tenant Recognition
Agreement or Tenant Recognition Provisions, it being intended that Owner's sole
obligation with respect to any Non-Disturbance Agreement, Non-Disturbance
Provisions, Tenant Recognition Agreement or Tenant Recognition Provisions, shall
be to request, in good faith, before the date of execution of any future
Mortgage or Superior Lease to enter into such Non-Disturbance Agreement or
include Non-Disturbance Provisions in any future Mortgage or enter into such
Tenant Recognition Agreement or include Tenant Recognition Provisions in any
future Superior Lease, as the case may be. If required by the holder of any
future Mortgage or by the lessor under any Superior Lease, Tenant shall promptly
join in any commercially reasonable Non-Disturbance Agreement or Tenant
Recognition Agreement to indicate its concurrence with the provisions thereof.
If any holder of any such future such Mortgage or Superior Lease shall impose a
fee as a condition of entering into any such Non-Disturbance Agreement,
Non-Disturbance Provisions or Tenant Recognition Provisions, Owner may withdraw
its request for same unless, within ten (10) days next following Owner's advice
to Tenant as to such fee and the amount thereof, Tenant shall execute and
deliver to Owner a written agreement to pay Owner, as additional rent under this
Lease, a sum equal to the amount of such fee. If Tenant does not execute and
deliver such agreement within said period, Owner shall have the right to
withdraw its request for any such Agreement or Provision in which event Owner
shall have no further obligation to obtain same.


               FIFTEENTH: (A) Owner Liability Limitation. Except as otherwise
expressly set forth herein to the contrary, Owner shall incur no liability of
any kind whatsoever to Tenant or to any person, firm or corporation claiming by,
through or under Tenant in connection with this Lease or the revocation thereof,
or the use by Tenant of all or any portions of the Demised Premises or the
Building. Owner shall have no responsibility or liability for any loss or damage
that may occur to Tenant's property or effects while located in the Demised
Premises or the Building unless such damage is due to the negligence of Owner.

                                       23
<PAGE>

No general or limited partner, officer, director, employee or shareholder of
Owner or any agent thereof shall be personally liable for the performance of
Owner's obligation under this Lease. The liability of for any Owner's obligation
under this Lease shall be limited to Owner's interest in the Building, and
Tenant shall not look to any of Owner's other assets for enforcement or
satisfaction of any such obligation, nor shall Tenant seek recourse for such
enforcement or satisfaction against any general or limited partner, officer,
director, employee or shareholder of Owner or any agent thereof. Tenant
acknowledges and agrees that (i) Owner shall not be obligated to provide
security or any other type of protection for any equipment, personal property or
installation in the Demised Premises, (ii) neither Owner nor its agents shall be
liable or responsible to Tenant for any loss or damage to any property or person
occasioned by theft, fire, act of God, public enemy, injunction, riot, strike,
insurrection, war, court order, requisition or other order of governmental body
or authority, or for any damage or inconvenience which may arise through
maintenance, repair or alteration of any part of the Building. Owner and Tenant
agree that neither party shall be liable to the other for any special or
consequential damages, including lost profits or revenues, as a result of such
parties' default of its obligations under this Lease, provided that nothing
contained herein shall otherwise limit, modify or violate any claim or remedy in
law or equity by one party hereof against the other by reason of a breach or
default in the other's obligations under this Lease.

                             (B) Owner's Indemnity: Notwithstanding the
foregoing provisions of (A) hereof, Owner agrees to indemnify and save Tenant
and Tenant's agents harmless of and from all loss, cost, liability, damage and
expense, including, but not limited to, reasonable counsel fees, penalties and
fines incurred in connection with or arising from (i) any default by Owner in
the performance or observance of any of the terms, covenants or conditions of
this Lease on Owner's part to be observed or performed, or (ii) any acts,
omissions or negligence of Owner or its employees, agents, contractors or
servants in or about the demised Premises or the Building either prior to,
during, or after, the expiration of the Demised Term. Owner further agrees to
indemnify and save harmless Tenant and its agents of an from all loss, cost,
liability, damage, and expense, including, but not limited to, reasonable
counsel fees incurred in connection with or arising from any claims by any
persons or damage to property occasioned by any act, omission or negligence
referred to in the preceding sentence. If any action or proceeding shall be
brought against Tenant or Tenant's agents based upon any such claim and if
Owner, upon notice from Tenant, shall cause such action or proceeding to be
defended at Owner's expense by counsel acting for Owner's insurance carriers in
connection with such defense or by other counsel reasonably satisfactory to
Tenant, without any disclaimer of liability by Owner in connection with such
claim, Owner shall not be required to indemnify Tenant or Tenant's agents for
counsel fees in connection with such action or proceeding.

during the Demised Term, any one or more of the following events (referred to as
"Events of Default") shall occur: (i) if Tenant shall default in the payment
when due of any installment of Fixed Rent or in the payment when due of any
other sums due Owner hereunder, and such default shall continue for a period of
ten (10) days after notice by Owner to Tenant of such default, or (ii) if Tenant
shall default in the observance or performance of any term, covenant or
condition (other than the covenants to make payment of Fixed Rent or other sums
due Owner) of this Lease on Tenant's part to be observed or performed and Tenant
shall fail to remedy such default within thirty (30) days after notice by Owner

                                       24

to Tenant of such default; or (iii) if Tenant shall file a voluntary petition in
bankruptcy or insolvency, or such proceeding shall be commenced against Tenant
or Tenant shall be adjudicated a bankrupt or insolvent, or Tenant shall file or
there shall be filed against Tenant any petition or answer seeking any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar relief under present or any future federal bankruptcy act or any
other present or future applicable federal, state or other statute or law, or
Tenant shall make an assignment for the benefit of creditors, or Tenant shall
seek or consent to or acquiesce in the appointment of any trustee, receiver or
liquidator for Tenant or of all or any part of Tenant's property; or (iv) if
Tenant shall desert or abandon the Demised Premises or Tenant's equipment; or
(v) if Tenant's interest in this Lease shall devolve upon or pass to any person,
whether by operation of law or otherwise except as provided in Article NINTH
hereof then, upon the occurrence, at any time prior to or during the Demised
Term, of any one or more of such Events of Default, Owner, at any time
thereafter, at Owner's option, may give to Tenant a five (5) days' notice of
termination of this Lease and, in the event such notice is given, this Lease and
the Demised Term shall come to an end and expire upon the expiration of said
five (5) days with the same effect as if the date of expiration of said five (5)
days were the expiration date of the Demised Term and this Lease, but Tenant
shall remain liable for damages and all other sums payable pursuant to law. Any
notice given by Owner to Tenant under this Article SIXTEENTH shall be deemed a
"ten day notice to quit" under the provisions of Section 713 of the Real
Property Actions and Proceedings Law.

                             (B) In the event that this Lease shall end, Owner
and its agents and servants may immediately, or at any time after such default
or after the date upon which this Lease and the Demised Term shall expire and
come to an end, re-enter the Demised Premises or any part thereof, without
notice, either by summary proceedings or by any other applicable action or
proceeding, or by force or otherwise (without being liable to indictment,
prosecution or damages therefor), and may repossess the Demised Premises and
dispossess Tenant and any other persons from the Demised Premises and remove
any and all of their property and effects from the Demised Premises including
Tenant's equipment and Owner, at Owner's option, may release the whole or any
part or parts of the Demised Premises, from time to time, either in the name of
Owner or otherwise, to such tenant or tenants, for such term or terms ending
before, on or after the expiration date of the Demised Term, at such rental or
rental fees or otherwise and upon such other conditions, which may include
concessions and free rent periods, as Owner, in its sole discretion, may
determine. Tenant hereby waives the service of any notice of intention to
re-enter or to institute legal proceedings to that end which may otherwise be
required to be given under any present or future law. Tenant, on its own behalf
and on behalf of all persons claiming through or under Tenant, including all
creditors, does further hereby waive any and all rights which Tenant and all
such persons might otherwise have under any present or future law to redeem the
Demised Premises, or to re-enter or repossess the Demised Premises, or to
restore the operation of this Lease, after (i) Tenant shall have been
dispossessed by a judgment or by warrant of any court or judge, or (ii) any
re-entry by Owner, or (iii) any expiration or termination of this Lease and the
Demised Term, whether such dispossess, re-entry, expiration or termination shall
be by operation of law or pursuant to the provisions of this Lease.

               SEVENTEENTH: Inability to Perform. If, by reason of strikes or
other labor disputes, fire or other casualty (or reasonable delays in adjustment
of insurance), accidents, Legal Requirement or any orders of any Government
Authority, or any other cause beyond Owner or Tenant's reasonable control,
whether or not such other cause shall be similar in nature to those hereinbefore
enumerated, Owner or Tenant, as the case may be, is unable to perform, fulfill
or is delayed in fulfilling any of their respective obligations under this Lease
or any instrument collateral thereto, then the performance or observance of such
obligation shall be suspended to the extent of and during the duration of such
inability and (i) no such inability or delay shall constitute an actual or
constructive eviction of Tenant, in whole or in part, or entitle Tenant to any
abatement or diminution of any of the Fixed Rent or any other sum due Owner from
Tenant hereunder, or (ii) no such inability or delay shall relieve Owner or
Tenant, as the case may be, from any of their respective obligations under this
Lease which are not affected by such inability or delay, or impose any liability
upon Owner, or Tenant as the case may be, or their agents, by reason of
inconvenience or annoyance to the other party, or injury to or interruption of
Tenant's business, or otherwise. The provisions of this Article SEVENTEENTH
shall not apply to the obligations of either Owner or Tenant to pay any monies
due the other party. Owner and Tenant, as the case may be applicable, each
agrees to employ reasonable diligence to eliminate the cause of any inability or
delay referred to in this Article, however, the provisions of this sentence
shall not apply in the event of any strike or labor dispute and neither party
shall be required to employ labor at overtime or any other premium pay rates
unless there is a danger or threatened danger to the health or safety of any
occupant of the Building or the environmental condition thereof.

constitutes the entire understanding between the parties with respect to the
transaction contemplated herein. This Lease may not be modified, amended or
terminated, and Tenant's obligations hereunder shall in no way be discharged,
except as expressly provided in this Lease or by written instrument executed by
the parties hereto. This Lease shall be governed by and construed in accordance
with the laws of the State of New York. This Lease shall not be binding or
effective until this Lease is executed and delivered by Owner and Tenant. This

associations and any other private or public entities, whether any of the
foregoing are acting on their own behalf or in a representative capacity. If any
term, covenant or condition of this Lease or any application thereof shall be
invalid or unenforceable, the remainder of this Lease and any other application
of such term, covenant or condition shall not be affected thereby. This Lease
shall be construed without regard to any presumption or other rule requiring
construction against the party causing this Lease to be drafted. In the event of
any action, suit, dispute or proceeding affecting the terms of this Lease, no
weight shall be given to any deletions or striking out of any of the terms of
this Lease contained in any draft of this Lease and no such deletion or strike
out shall be entered into evidence in any such action, suit or dispute or
proceeding given any weight therein.

                             (C) Owner and Tenant mutually represent and warrant
to the other that they had no dealings with any brokers, consultants,
individuals or any other entities in the negotiation and/or consummation of this
Lease other than C.B. Richard Ellis. Owner and Tenant hereby mutually agree to
indemnify and hold the other party harmless from and against any claims, costs,
expenses (including, without limitation, legal fees) and other liabilities
incurred by the other party by reason of any claim or action for a commission or
fee or other compensation by any person or broker in connection with this Lease

thereto.

                             (J) Courtyard: Subject to the applicable provisions
of this Lease including, but not limited to, any Legal Requirements of any
Governmental Authority, Tenant shall have the exclusive use of the courtyard,
as shown on Exhibit "3", which Owner shall initially mow and remove the existing
rubbish. During the Demised Term, Owner shall mow said courtyard on an ongoing
basis, provided Tenant grants Owner reasonable access thereto during regular
business hours and Tenant uses reasonable efforts to maintain said courtyard in
reasonably good order and condition. Tenant shall also have the right to enclose
said courtyard, subject to Owner's reasonable approval (including the reasonable
approval of the type of "fencing" used) and the approval of any Legal
Requirements of any Governmental Authority. Tenant shall maintain such "fencing"
or other improvements in or about the courtyard in good order, repair and
condition throughout the Demised Term.

shall not lease any space in the Building or Real Property to any tenant or
occupant which uses any such space for heavy manufacturing. However, light

               TWENTIETH. Security. Letter of Credit: (A) (1) Tenant has
deposited with Owner, at the time of the execution and delivery of this Lease,
an unconditional, irrevocable letter of credit issued by a lending institution
acceptable to Owner (referred to as the "Bank"), in favor of Owner, in the sum
of TWO HUNDRED NINETY TWO THOUSAND NINE HUNDRED EIGHTY and 45/100 ($292,980.45)
DOLLARS (referred to as the "Security Amount") in funds available immediately or
same day funds in the City of New York, as security for the faithful observance
and performance by Tenant of the terms, covenants and conditions of this Lease
on Tenant's part to be observed and performed. Such letter of credit is for a
term of not less than one (1) year which term shall be automatically renewed for
successive one (1) year terms, unless the Bank gives not less than one hundred
twenty (120) days prior written notice that it will not so renew the letter of
credit for such successive term and the last term of the letter of credit shall
end not less than sixty (60) days after the Expiration Date. If such letter of
credit is not automatically renewed as aforesaid, Tenant agrees to cause the
Bank to renew such letter of credit, from time to time, during the Demised Term,
at least ninety (90) days prior to the expiration of said letter of credit or
any renewal or replacement, upon the same terms and conditions. In the event of
any transfer of said letter of credit pursuant to Paragraph F, and notice of
such transfer to Tenant, Tenant, within twenty (20) days thereafter, shall cause
a new letter of credit to be issued by said Bank to the transferee, upon the
same terms and conditions, in replacement of the letter of credit so transferred
and Owner agrees that, simultaneously with the delivery of such new letter of
credit, it will return to said Bank the letter of credit being replaced. The
letter of credit deposited hereunder, and all renewals and replacements, are
referred to, collectively, as the "Letter of Credit". In amplification and not
in limitation of the foregoing, the Letter of Credit shall expressly provide
that (i) the Letter of Credit can be drawn down by presentation of a sight draft
only without any other documents or statements, (ii) partial drawings are
allowed and (iii) the Letter of Credit shall be transferable by Owner, as
beneficiary thereof, without restriction or limitation and with all fees paid by
Tenant.

                                            (2) The Letter of Credit shall be
held by Owner for the purposes set forth in this Article and shall not be
transferred except for transfer (a) to an agent for collection, or (b) pursuant
to the provisions of Paragraph F. In the event Tenant defaults beyond any
applicable grace period hereunder in the performance of its obligations to issue
a replacement Letter of Credit, or in the observance or performance of Tenant's
agreement to cause the Bank to renew the Letter of Credit, Owner, in addition to
all rights and remedies which Owner may have under this Lease or at law, shall
have the right to require the Bank to make payment to Owner of the entire
Security Amount or the undrawn portion thereof, as the case may be, represented
by the Letter of Credit, which sum may be held by Owner as Cash Security (as
said term is hereinafter defined) in accordance with the provisions of this
Article. If payment of the entire Security Amount or the undrawn portion thereof
is made to Owner by reason of Tenant's failure to renew or replace the Letter of
Credit in accordance with the foregoing provisions of this Article, Owner shall
have the right, at any time on behalf of Tenant, to replace said Cash Security
with a new Letter of Credit issued by the Bank or any other bank selected by
Owner, in Owner's sole discretion, and Tenant hereby irrevocably constitutes and
appoints Owner as Tenant's agent and attorney-in-fact to cause the Bank or any
such other bank selected by Owner to issue such a replacement Letter of Credit.
The Letter of Credit provides for partial drawings.

                                       29
<PAGE>

                                            (3) In the event Tenant defaults in
the payment when due of
an installment of Fixed Rent or in the payment when due of any additional rent
and such default shall continue for a period of ten (10) days after notice by
Owner to Tenant of such default or if this Lease and the Demised Term shall
expire and come to an end as provided in Article SIXTEENTH or by or under any
summary proceeding or any other action or proceeding, or if Owner shall re-enter
the Demised Premises as provided in Article 17, or by or under any summary
proceeding or any other action or proceeding, then Owner, in addition to all
rights and remedies which Owner may have under this Lease or at law, may from
time to time, draw on the Letter of Credit in one or more drawings for the
amount of any Fixed Rent or additional rent then due and for any amount then due
and payable to Owner under this Lease. In the event of a partial drawing, as
provided in the immediately preceding sentence, Tenant shall, within five (5)
days after demand, cause the Bank to issue an amendment to the Letter of Credit
restoring the amount available thereunder to the Security Amount. In
amplification and not in limitation of the provisions of this Lease, a failure
by Tenant to cause the Bank to issue an amendment to the Letter of Credit
restoring the amount available thereunder to the Security Amount shall be deemed
a default by Tenant under the terms, covenants and conditions of this Lease.
Notwithstanding anything to the contrary set forth in this Lease, including, but
not limited to, the foregoing provisions of this Article, in addition to all
rights granted to Owner pursuant to the provisions of the Lease, if this Lease
and the Demised Term shall expire and come to an end as provided in Article
SIXTEENTH, or by or under any summary proceeding, or any other action or
proceeding, or if Owner shall re-enter the Demised Premises as provided in
Article 17, or by or under any summary proceeding or any other action or
proceeding, Owner, in addition to all rights and remedies which Owner may have
under this Lease or at law, shall have the right to require the Bank to make
payment to Owner of the entire Security Amount or the undrawn portion thereof,
as the case may be, represented by the Letter of Credit, which sum shall be held
and applied by Owner as Cash Security in accordance with the provisions of this
Article.

                             (B) Any sum held by Owner as cash security ("Cash
Security") shall be held subject to the provisions of Section 7-103 of the
General Obligations Law or any similar statute successor thereto.

                             (C) Application of Cash Security: In the event
Tenant defaults in the observance or performance of any term, covenant or
condition of this Lease on Tenant's part to be observed or performed, including,
but not limited to, the covenant for the payment of Fixed Rent and additional
rent, beyond the applicable grace period provided under this Lease for curing
such default, Owner may use, apply or retain the whole or any part of any Cash
Security held by Owner under any of the provisions of Paragraph A hereof, to the
extent required for the payment of any Fixed Rent, additional rent or any other
sum with respect to which Tenant is in default, or for the payment of any sum
which Owner may expend or incur because of Tenant's default in the observance or
performance of any such term, covenant or condition, including, but not limited
to, the payment of any damages or deficiency in the reletting of the Demised
Premises, whether such damage or deficiency accrued before or after summary
proceedings or other re-entry by Owner, without thereby waiving any other rights
or remedies of Owner with respect to such default, and Owner shall hold the
remainder of such Cash Security as security for the faithful performance and
observance by Tenant of the terms, covenants and conditions of this Lease on
Tenant's part to be observed and performed with the same rights as hereinabove

                                       30
<PAGE>

set forth to use, apply or retain all or any part of such remainder in the event
of any further default by Tenant under this Lease.

                             (D) Restoration of Cash Security: If Owner uses,
applies or retains the whole or any part of the Cash Security held by Owner
under any of the provisions of Paragraph A., Tenant, promptly after notice
thereof, shall deliver to Owner, in cash or by a cashier's check, or Tenant's
certified check, in either case drawn by or on a bank which is a member of the
New York Clearing House Association and payable to the order of Owner, the sum
necessary to restore the Cash Security to the Security Amount. In Amplification
and not in limitation of the provisions of this Lease, a failure by Tenant to
so replenish the Cash Security to the Security Amount shall be deemed a default
by Tenant under the terms, covenants and conditions of this Lease.

                             (E) Return of Security: The Letter of Credit and/or
any remaining portion of any Cash Security then held by Owner for the
performance of Tenant's obligations under this Lease as security shall be
returned to Tenant after (i) the Expiration Date and (ii) the full observance
and performance by Tenant of all of the terms, covenants and conditions of this
Lease on Tenant's part to be observed and performed, including, but not limited
to, the provisions of EIGHTH.

                             (F) Transfer of Letter of Credit: In the event of a
sale or other transfer of the Land and/or Building, or Owner 's interest in this
Lease, Owner shall transfer the Letter of Credit and/or any remaining portion of
any Cash Security then held by Owner as security for the performance of Tenant's
obligations under this Lease to the transferee, and Owner shall thereupon be
released from all liability for the return of such security; Tenant agrees to
look solely to the transferee for the return of any such security and it is
agreed that the provisions of this sentence shall apply to every sale or
transfer of the Land and/or Building or Owner's interest in this Lease by Owner
named herein or its successors, and to every transfer or assignment made of any
such security. Any transferee shall be deemed to have agreed that any Letter of
Credit or Cash Security transferred to such transferee pursuant to this Section
shall be held in accordance with the provisions of this Article for the purposes
of this Article. A lease of the entire Building pursuant to which the lessee
shall be entitled to collect the rents hereunder shall be deemed a transfer
within the meaning of this Section.

                             (G) Deposit of Cash Security in Interest-Bearing
Account: Subject to Owner's right to replace the Cash Security with a new Letter
of Credit in accordance with the provisions of Paragraph A, Owner agrees that,
if not prohibited by law or the general policies of lending institutions in New
York City, Owner shall deposit any Cash Security held by Owner in an
interest-bearing savings account at a bank or banks selected by Owner, and all
interest accruing thereon shall be added to and become part of such Cash
Security and shall be retained by Owner under the same conditions as the
principal sum held as Cash Security. Notwithstanding anything to the contrary
set forth in this Article with respect to any Cash Security, Owner shall be
entitled to retain the one (1%) percent administrative fee permitted by law to
be retained by landlords with respect to cash security deposits or any such
lesser percentage as reasonable under the circumstances.

                                       31
<PAGE>

                             (H) No Assignment of Security by Tenant: Tenant
agrees that it will not assign, mortgage or encumber, or attempt to assign,
mortgage or encumber, the Letter of Credit or any Cash Security held by Owner
under this Lease, and that neither Owner nor its successors or assigns shall be
bound by any such assignment, mortgage, encumbrance, attempted assignment,
attempted mortgage or attempted encumbrance. Owner shall not be required to
exhaust its remedies against Tenant before having recourse to the Letter of
Credit, the Cash Security or any other security held by Owner. Recourse by Owner
to the Letter of Credit, the Cash Security or any other security held by Owner
shall not affect any remedies of Owner which are provided in this Lease or which
are available in law or equity.

                             (I) Partial Return of Security: Owner has agreed
that Owner shall return
to Tenant the sum of FORTY EIGHT THOUSAND EIGHT HUNDRED THIRTY and 08/100
($48,830.08) DOLLARS of such security on the date (referred to as the "Partial
Return Date") which is the first (1st) anniversary of the Rent Commencement Date
and the further sums of FORTY EIGHT THOUSAND EIGHT HUNDRED THIRTY and 08/100
($48,830.08) DOLLARS on each successive anniversary of said Partial Return Date
for each of the next three (3) years thereafter, provided Tenant is not then in
default under any of the terms, covenants or conditions of this Lease on
Tenant's part to be observed and performed. Accordingly, if on the Initial
Partial Return Date and each anniversary dates thereafter as set forth above,
Tenant shall not so be in default, Tenant may replace the Letter of Credit with
a Letter of Credit in a sum reduced by FORTY EIGHT THOUSAND EIGHT HUNDRED THIRTY
and 08/100 ($48,830.08) DOLLARS on such Partial Return Date and on each such
successive anniversary date thereof for each of the next three (3) years as set
forth herein. In the event that at any time Tenant shall be entitled to reduce
such Letter of Credit as provided in the foregoing provisions of this Article
the security shall be held as Cash Security then, in lieu of Tenant replacing
any such Letter of Credit, Owner shall return sums to Tenant equal to the amount
by which the Letter of Credit would have been reduced if it were in existence;
however, in no event shall the Letter of Credit or Cash Security ever be reduced
below the sum of NINETY SEVEN THOUSAND SIX HUNDRED SIXTY and 13/100 ($97,660.13)
DOLLARS. The sum of TWO HUNDRED NINETY TWO THOUSAND NINE HUNDRED EIGHTY and
45/100 ($292,980.45) DOLLARS referred to in the previous Paragraphs of this
Article shall be deemed reduced as the provisions of this Paragraph shall
operate to so reduce the Letter of Credit and/or Cash Security, as the case may
be.

               TWENTY-FIRST. Tax Escalation. (A) Definitions: In the
determination of any increase in the Fixed Rent under the provisions of this
Article, Owner and Tenant agree that the following terms shall have the
following meanings:

                                            (1) The term "Tax Escalation Year"
shall mean each fiscal year commencing December 1st and ending on the following
November 30th which shall include any part of the Demised Term.

                                            (2) The term "Taxes" shall be deemed
to mean a sum equal to all real estate taxes and assessments, special or
otherwise, upon or with respect to the Real Property imposed by the Town of
Islip, County of Suffolk or any other taxing authority to create a source of
revenue through taxation of real estate as such. If, due to any change in the
method of taxation, any franchise, income, profit, sales, rental, use and
occupancy or other tax or payments in lieu of any such taxes shall be

                                       32
<PAGE>

substituted for, or levied against Owner or any owner of the Building or the
Real Property, in lieu of any real estate taxes or assessments upon or with
respect to the Real Property, such tax or payments in lieu of any such taxes
shall be included in the term Taxes for the purposes of this Article.

                                            (3) The term "Tenant's Proportionate
Share" shall mean the fraction, 32,610/355,000 (I.E. 9.19%).

                                            (4) The term "Owner's Basic Tax
Liability" shall mean a sum equal to Taxes, as finally determined, payable for
the Tax Escalation Year commencing December 1st, 2003 and expiring
November 30th, 2004. As of the date hereof, there are no Tax abatements
affecting the Building and/or Real Property.

               (B) If Taxes payable in any Tax Escalation Year shall be in such
amount as shall constitute an increase above Owner's Basic Tax Liability, the
Fixed Rent for such Tax Escalation Year shall be increased by a sum equal to
Tenant's Proportionate Share of any such increase. Tenant shall pay any such
amounts owing to Owner pursuant to the foregoing provisions of this Article
within ten (10) days after the submission by Owner to Tenant of a bill therefor,
Tenant's obligation to make such payments shall survive the expiration or sooner
termination of this Lease. All sums payable under this Article shall be
collectible by Owner in the same manner as Fixed Rent.

               TWENTY-SECOND.Right of First Refusal: (A) Provided Tenant is not
then in default in the observance and performance of any of the terms, covenants
or conditions of this Lease on Tenant's part to be observed or performed, in the
event that at any time during the Demised Term (a) any space (referred to as
"Option Space") in the Building shall become available for leasing during the
Demised Term which is contiguous to the Demised Premises as then configured and
(b) Owner shall receive a bona fide offer to lease any such Option Space (any
such offer is referred to as an "Option Space Offer"), and (c) Owner shall find
such Option Space Offer to be acceptable in Owner's sole judgment, and (d)
Tenant, in contradistinction to sub-tenants or other occupants, shall then be in
occupancy of at least 80% of the space leased to Tenant under this Lease, Owner
shall give notice of such Option Space Offer to Tenant, and Tenant shall have
the option, exercisable by notice given to Owner within ten (10) days next
following the date of the giving of such notice by Owner to Tenant to lease the
Option Space referred to in said notice upon the same terms and conditions set
forth in the Option Space Offer (except that Owner shall perform "Owner's
Initial Construction" (exclusive of any Tenant overages as described in Article
FIRST (B)) in any such Option Space in a like manner, on a pro-rata dollar, per
square foot basis, at Owner's expense, as performed initially in the original
Demised Premises, provided, however, that from and after the Commencement Date,
Owner's expenditure with respect to such "Owner's Initial Construction" to be
performed in any Option Space shall be reduced by 1/130 of such total cost per
month (exclusive of any such Tenant overages) and that the Fixed Rent for any
Option Space, the exercise for which by Tenant on or prior to the first (1st)
anniversary of the Commencement Date, shall be at the same rental rate as set
forth in the Lease and, thereafter, at ninety-five (95%) percent of fair market
value, as otherwise determined in this Article) for a term to expire on the
Expiration Date.

                                       33
<PAGE>

                             (B) No space in the Building shall be deemed
"available for leasing" if (a) the then tenant of such space, or any assignee,
subtenant or other occupant through or under such tenant, shall enter into (i)
any agreement with Owner extending the letting agreement affecting such space,
or (ii) any new lease with Owner affecting such space, or (b) any other existing
tenant in the Building or any assignee of such other tenant shall exercise any
contractual option or right which such tenant has to lease such space existing
as of the date hereof. Notwithstanding the foregoing provisions of this Article
TWENTY-SECOND, Tenant shall not have the right to lease and add to the Demised
Premises any space which becomes available for leasing if, at the time of the
exercise of such option by Tenant, the remaining term of this Lease is less than
two (2) years, unless Tenant has executed its Renewal Option in this Lease.

                             (C) In the event that Tenant shall timely exercise
any option contained in this Article, Owner and Tenant, within thirty (30) days
after the giving of the Additional Option Notice, shall enter into an additional
space agreement (each such additional space agreement is referred to as an
"Additional Agreement") which modifies this Lease by adding the applicable
Option Space to the Demised Premises. Any Additional Agreement shall provide for
a leasing of the applicable Option Space at an annual rental rate equal to the
annual rental rate set forth in the applicable Option Space Offer and otherwise
upon all of the other terms, covenants and conditions set forth in such Option
Space Offer.

                             (D) Notwithstanding the foregoing, Owner shall only
be required to give Tenant a single Additional Option Notice for any Option
Space for which Owner receives an Option Space Offer. Thereafter, Owner is free
to lease any such space to a third (3rd ) party as Owner deems fit.

                             (E) Time is of the essence with respect to (a) the
giving of any applicable Additional Option Notice and (b) the execution and
delivery of any applicable Additional Agreement. In the event Tenant shall fail
to (i) give any applicable Additional Option Notice within (10) days after the
giving of the notice by Owner to Tenant of the availability of any such Option
Space, or (ii) execute and deliver to Owner any applicable Additional Agreement
within thirty (30) days after the date of the giving of any applicable
Additional Option Notice, the rights of Tenant under this Article shall be
deemed of no further force and effect with respect to the particular leasing to
which the Option Space Offer relates, but the rights of Tenant under this
Article shall otherwise remain in full force and effect. Any Additional Option
Notice given by Tenant after such ten (10) day period purporting to exercise
such right and any execution and delivery of any Additional Agreement by Tenant
after such thirty (30) day period shall be void and of no force or effect.

                             (F) Upon the request of Owner, from time to time,
Tenant shall execute and deliver to Owner an instrument, in form reasonably
satisfactory to Owner, stating (i) whether or not Tenant has exercised any such
option to lease any Option Space pursuant to the provisions of this Article, and
 in the event thatTenant has so exercised such right, (ii) either stating the
principal terms and conditions of each Additional Agreement or, if such be the
case, stating that Tenant has failed to execute and deliver such Additional
Agreement within such thirty (30) day period and, accordingly, acknowledging

                                       34
<PAGE>

that such Additional Agreement is void and of no force and effect and that
Tenant has no further rights with respect to the Option Space referred to
therein.

               TWENTY-THIRD. Tenant's Single Renewal Option. (A) Provided Tenant
is not then in default under any of the terms, covenants or conditions of this
Lease on Tenant's part to be observed or performed, Tenant shall have the single
option to renew this Lease with respect to all or any portion of the Demised
Premises designated by Tenant (provided the portion not so renewed is reasonably
configured so that Owner may lease same to a third (3rd) party as a
self-contained unit) and the Demised Term for a single renewal term of five (5)
years (referred to herein as the "Renewal Term") commencing on the date next
following the Expiration Date (the "Renewal Term Commencement Date") and ending,
unless sooner terminated pursuant to the provisions of this Lease or pursuant to
law, on the last day of the calendar month immediately preceding the fifth (5th)
anniversary of the Renewal Term Commencement Date (referred to as the "Extended
Expiration Date"). If Tenant exercises such option in accordance with the
provisions and limitations of this Article, this Lease and the Demised Term
shall be renewed for such Renewal Term: (i) upon an annual rental rate equal to
ninety-five (95%) percent of the fair market annual rental value of comparable
space in the Building for the twelve (12) month period prior to the Expiration
Date, as determined by agreement between Owner and Tenant, or by arbitration in
accordance with the provisions of B hereof, and (ii) except as hereinafter
provided, upon all of the other then executory terms, covenants and conditions
contained in this Lease (including, but not limited to, the definition of
"Owner's Basic Tax Liability" set forth in Article TWENTY-FIRST), and the
Expiration Date shall be deemed extended to the Extended Expiration Date.

                             (B) In the event Owner and Tenant are unable to
agree as to the fair
market annual rental value of the Demised Premises pursuant to A, such fair
market annual rental value shall be determined by arbitration, as follows:

                                            (1) Owner and Tenant shall each
appoint an arbitrator within thirty (30) days after notice by either party
requesting arbitration of the issue. If either Owner or Tenant shall have
failed to appoint an arbitrator within such period of time, then, upon request
of either Owner or Tenant, as the case may be, such arbitrator shall be
appointed by the American Arbitration Association, or its successor, or if at
any time such association is not in existence and has no successor, then, by the
Presiding Justice of Appellate Division, First Department, of the Supreme Court
of the State of New York, or any successor court.

                                            (2) The two arbitrators appointed as
above provided, shall select a third arbitrator and if they fail to do so within
thirty (30) days after their appointment, such third arbitrator shall be
appointed as above provided for the appointment of an arbitrator in the event
either party fails to do so.

                                            (3) All of such arbitrators shall be
commercial real estate appraisers or brokers having at least fifteen (15) years
of experience in such field in the County of Suffolk.

                                       35
<PAGE>

                                            (4) The three arbitrators, selected
as aforesaid, forthwith shall convene and render their decisions as promptly as
practicable after the appointment of the third arbitrator. The decision of such
arbitrators shall be in writing and the vote of the majority of them (or, if
there shall be no majority decision, then the decision of the last appointed
arbitrator) shall be the decision of all and binding upon Owner and Tenant
whether or not a judgment shall be entered in any court. Duplicate original
counterparts of such decision shall be sent by the arbitrators to both Owner
and Tenant.

                                            (5) The arbitrators, in arriving at
their decision, shall take into consideration the escalation base year set forth
in Article TWENTY-FIRST, the fact that no free rent period or money allowance
shall be given to Tenant for the Renewal Term and the fact that the Demised
Premises shall be taken by Tenant "as is" for the Renewal Term, or, if there are
construction costs or construction time or other lease procurement, costs, then
same shall be taken into consideration, the fact that there is a brokerage
commission and that there is no so-called "down-time" during which Owner is not
receiving rent with respect to the Renewal Term and the arbitrators shall also
be entitled to consider all testimony and documentary evidence which may be
presented at any hearing as well as facts and data which the arbitrators may
discover by investigation and inquiry outside of such hearings. The arbitrators
shall be bound by the provisions of this Lease, and shall not add to, subtract
from, or otherwise modify such provisions. The cost and expense of such
arbitration shall be borne equally by Owner and Tenant, except that each party
shall pay its own counsel fees and expenses.

                             (C) The option set forth in A. may only be
exercised by notice given by Tenant to Owner on or prior to the date which is
twelve (12) calendar months immediately prior to the Expiration Date. Time is of
the essence with respect to the exercise of such option. Tenant shall not have
the right to give any such notice after the Notice Date, and any notice given
after the Notice Date purporting to exercise such option shall have no force and
effect.

                             (D) Tenant, upon request of Owner, from time to
time, will execute and deliver to Owner an instrument in form reasonably
satisfactory to Owner stating whether or not Tenant has exercised the option
contained in the provisions of A hereof.

               TWENTY-FOURTH.Tenant's Floating Termination Option: (A) For the
purposes of this Article, the term "Owner's Repayment Expenses" shall be deemed
to be a sum equal to the aggregate of: (a) a sum equal to the actual cost and
expense to Owner of performing Owner's Initial Construction (including, but not
limited to, the cost to Owner of a field superintendent, operating engineer,
laborers, freight elevator costs, rubbish removal, temporary sprinkler and
lighting, electric and heat, protection, insurance, Building Department filing
and expediting, building permits, blueprint costs and every other item which
customarily would be considered a general condition, and, if applicable, any
construction management or other fees paid to the general contractor or
construction manager who is performing Owner's Initial Construction, and, if
there is no general contractor or construction manager who is performing Owner's
Initial Construction, 10% of such actual cost and expense to Owner of performing
Owner's Initial Construction for office overhead and as a construction
management fee); plus (b) any brokerage commissions paid or payable by Owner in
connection with this Lease; plus (c) the total sum of the Fixed Rent
conditionally excused by operation of the provisions of SECOND (c) plus (d) any

                                       36
<PAGE>

and all other expenses, whether directly or indirectly, expended by Owner with
respect to this Lease. For the purposes of this Article, the term "Termination
Percentage" shall mean the percentage obtained by dividing the total number of
days from the date next following the sixth (6th) anniversary date of the Rent
Commencement Date and each successive anniversary date of the Rent Commencement
Date thereafter to and including the Expiration Date fixed pursuant to Article
FIRST, both dates inclusive, by the total number of days in the Demised Term.
For the purposes of this Article, the term "Termination Consideration" shall be
deemed to be a sum equal to Owner's Repayment Expenses, multiplied by the
Termination Percentage, together with interest thereon at the rate of eight (8%)
percent per annum from the date upon which Owner made payments of any portions
of Owner's Repayment Expenses, or the date upon which Owner granted a rent
holiday in connection therewith, to the date upon which the Termination
Consideration is paid by Tenant to Owner.

                             (B) Tenant shall have the right to terminate this
Lease as of the sixth (6th) anniversary date of the Rent Commencement Date and
each successive anniversary date of the Rent Commencement Date thereafter
(referred to as the "Tenant's Earlier Termination Date") provided (i) this
Lease has not been terminated previously pursuant to the provisions of this
Lease or pursuant to law; (ii) Tenant is not then in default under any of the
terms, covenants or conditions of this Lease on Tenant's part to be observed or
performed; (iii) Tenant shall give notice to Owner of Tenant's exercise of such
right to so terminate this Lease not later than the date which is nine (9)
months prior to the Tenant's Earlier Termination Date (referred to as the
"Termination Option Notice Date"); and (iv) simultaneously with the giving of
such notice, Tenant shall pay to Owner by cash, certified or teller's check to
the order of Owner drawn upon a bank which is a member of the New York Clearing
House a sum equal to one-half (1/2) of the Termination Consideration (if known
at such time when said payment is due or, if not known, a good faith estimate
thereof) with the remaining one-half (1/2) of said Termination Consideration to
be paid not less than forty-five (45) days prior to Tenant's Earlier Termination
Date which sums shall be in addition to the Fixed Rent and additional rent
payable by Tenant under the provisions of this Lease. Time is of the essence
with respect to the giving of such notice before the Termination Option Notice
Date and any notice given after the Termination Option Notice Date purporting to
exercise such option shall be void and of no force or effect. In the event
Tenant shall give any such notice of termination pursuant to the provisions of
this Section and shall otherwise comply with the conditions of the exercise of
Tenant's right to terminate this Lease, including, but not limited to, the
payment of the sum referred to in subsection (iv), this Lease and the Demised
Term shall come to an end and expire on the Tenant's Earlier Termination Date
with the same force and effect as though said date were the Expiration Date,
unless sooner terminated pursuant to any other term, covenant or condition of
this Lease or pursuant to law.

                             (C) Upon request of Owner, from time to time,
Tenant will execute and deliver to Owner an instrument, in form reasonably
satisfactory to both parties, stating that Tenant has not exercised the right of
termination contained in (B) hereof or that Tenant has exercised the right of
termination contained in (B) hereof, as the case may be. Failure of Owner to
request the execution and delivery of such instrument or failure of Tenant to
execute such instrument, however, shall not vitiate the foregoing provisions of
this Article.

               TWENTY-FIFTH: Signage: As used herein, the word "sign" shall be
construed to include, without limitation, any pylon, monumental, placard,
poster, light, awning, marquee or other advertising symbol or object,
irrespective of whether same shall be temporary or permanent.

               Subject to Owner's approval and the approval of any governing or
quasi-governing authority (herein, collectively, "Authority") having
jurisdiction thereover, Tenant shall have the right, at Tenant's sole expense,
to install a "sign" or "signs" up to the maximum permissible size per applicable
code of any such Authority.

               Tenant, at Tenant's expense, may install a "sign" or "signs" in
the Building directing the general public to the Demised Premises, subject to
Owner's approval, which shall not be unreasonably withheld.

               IN WITNESS WHEREOF, the parties hereto have hereunto set their
hands and seals as of the day and year first above written.
