          WITNESSETH: Landlord hereby leases to Tenant and Tenant hereby hires
from Landlord, the entire 6/th/ floor and portion of the 5/th/ floor as shown on
the floor plans annexed hereto and made a part hereof as Exhibit A (the "Demised
Premises" or "demised premises", whether capitalized or not) in the building
known as 67 a/k/a 75 Broad Street in the Borough of Manhattan, City of New York
(the "Building" or "Building", whether capitalized or not), for the term of
approximately fifteen (15) years and seven (7) months (or until such term shall
sooner cease and expire as hereinafter provided) to commence as provided in
Article 52 (the "Commencement Date") and shall expire nevertheless on the last
day of the 187/th/ calendar month following the Commencement Date (the
"Expiration Date"), both dates inclusive, at annual rental rates, as provided in
the Rent Schedule annexed hereto and made a part hereof as Exhibit B (the "fixed
rent" or "Fixed Rent" or "Fixed Annual Rent," whether capitalized or not), which
Tenant agrees to pay in lawful money of the United States which shall be legal
tender in payment of all debts and dues, public and private, at the time of
payment, in equal monthly installments in advance on the first day of each month
during said term, at the office of Landlord or such other place as Landlord may
designate, without any set off, counterclaim or deduction whatsoever unless
expressly provided for in this lease. The first (1st) monthly installment of
fixed rent shall be paid upon execution of this Lease by Tenant.

          The parties hereto, for themselves, their heirs, distributees,
executors, administrators, legal representatives, successors and assigns, hereby
covenant as follows:

          1.   Rent. Tenant shall pay the rent as above and as hereinafter
provided.

          2.   Occupancy. Tenant shall use and occupy the Demised Premises for
telecommunications and other communications equipment (Including, but not
limited to, switching gear) and executive, general, and administrative offices,
and for all lawful incidental or ancillary uses in connection with the
foregoing, and for no other purpose.

          3.   Alterations: Tenant shall make no structural changes in or to the
Demised Premises of any nature without Landlord's prior written consent
provided, however, that Tenant shall be permitted without the prior written
consent of Landlord to make non-structural alterations to the Demised Premises,
the cost of which, individually, do not exceed, $25,000.00 and which, when taken
in any one-year period, do not exceed $75,000.00 in the aggregate, provided that
such alterations do not adversely affect the exterior or interior of the
Building, the Certificate of Occupancy of the Building, or the structure or
working systems of the Building or adversely affect other Building tenants.
Furthermore, as to any non-structural alterations which exceed the initial
amounts or any adjusted amounts, Tenant shall not perform such non-structural
alterations without the prior written consent of the Landlord, which consent
shall not be unreasonably withheld, delayed or conditioned. It is understood by
the parties that Landlord shall be deemed to approve any request for consent by
Tenant under this Article 3 if Landlord fails to give Tenant written notice
approving, denying or requesting additional information within twenty (20) days
from the date Tenant has submitted plans to Landlord. Notwithstanding the
foregoing, Tenant may, at its sole cost, install floor coverings, objects of
art, wall and ceiling coverings, paneling, building standard window blinds and
trims regardless of cost without Landlord's consent. Also notwithstanding
Article 3, Tenant shall have no obligation to remove from the Demises Premises
any fixtures, paneling, partitions, railings or like installations, solely to
the extent installed by Landlord.

               With regards to Tenant's initial work, the plans and
specifications in respect of which shall be responded to in writing by Landlord
within ten (10) business days after Tenant submits a request for approval of the
same to Landlord. If Landlord shall not respond to Tenant's requested approval
of its plans and specifications within such ten (10) business day period, then
Landlord shall be deemed to have approved such plans and specifications.
Notwithstanding the foregoing, Tenant must use Landlord's base building
contractor for any electrical work in and to or from any base building
electrical service rooms, provided Landlord's contractor provides its service at
competitive market rates and quality. Tenant shall, at its expense, before
making any alterations, additions, installations or improvements obtain all
permits, approval and
<PAGE>

certificates required by any governmental or quasi-governmental bodies and (upon
completion) certificates of final approval thereof and shall deliver promptly
duplicates of all such permits, approvals and certificates to Landlord. Landlord
hereby agrees, at no cost and expense to it, to cooperate reasonably with Tenant
and agrees to execute all documents necessary for the procuring of any
governmental consents, permits, etc. Tenant agrees to carry and will cause
Tenant's contractors and sub-contractors to carry such workman's compensation,
general liability, personal and property damage insurance as Landlord may
reasonably require. If any mechanic's lien is filed against the Demised Premises
or the Building for work claimed to have been done for, or materials furnished
to, Tenant, whether or not done pursuant to this Article, the same shall be
discharged by Tenant within thirty (30) days after Tenant receives written
notice of the filing thereof at Tenant's expense, by either payment, the posting
of a statutory bond required by law or otherwise (e.g., by summary judgment for
a facial irregularity). Notwithstanding the foregoing, Tenant may remove any of
the fixtures and equipment delineated on Exhibit E provided it repairs any
damage occasioned by said removal. The foregoing notwithstanding Landlord
reserves the right at any time sixty (60) days prior to the Expiration Date to
require Tenant to remove any non-Building Standard installations. Nothing in
this Article shall be construed to give Landlord title to or to prevent Tenant's
removal of any fixtures, office furniture, equipment and like installations,
installed in the Demised Premises from time to time by Tenant, but upon removal
of any such furniture, fixtures and equipment from the Demised Premises or upon
removal of other installations as may be permitted hereunder, Tenant shall
immediately and at its expense, repair and restore the Demised Premises to the
condition existing prior to the installation, ordinary wear and tear,
obsolescence and damage by casualty, pursuant to Article 9, excepted, and repair
any damage to the Demised Premises or the Building due to such removal.

          With respect to any proposed work, Tenant shall, submit (a) "load
letter" evidencing Tenant's proposed floor and electrical loads and (b) final
"as built" plans.

          4.   Repairs: Landlord shall maintain and repair the exterior of the
Building and the structural portions of the Building, and all Building systems
servicing the Demised Premises including the structural portions of the Demised
Premises, provided such repair is not occasioned by Tenant's negligence or its
alterations; and the public portions of the Building and all Building systems
servicing the Demised Premises, (including, but not limited to, all plumbing,
electrical, heating and ventilating systems but expressly not Tenant's internal
system pursuant to Article 54 hereof). In addition to the foregoing, Landlord
shall maintain and keep in working condition and repair, only if supplied or
installed by Landlord, the radiators, central air conditioning equipment and
ducting, electrical conduit and risers, lighting fixtures, water columns and
pipes, serving the Demised Premises, provided such need for repair is not caused
by Tenant, its agents, employees or contractors. Tenant shall, throughout the
term of this lease, take good care of the Demised Premises including the windows
and window frames and, the fixtures and appurtenances therein and at Tenant's
sole cost and expense promptly make all repairs thereto and to the Building,
whether structural or non-structural in nature, caused by or resulting from the
carelessness, omission, neglect or improper conduct of Tenant, Tenant's
servants, employees, invitees, or licensees. In no event shall Tenant be
obligated to make any repairs (structural or non-structural) or replacements
necessitated by, or to repair damage due, in whole or in part, to any act,
omission or negligence of Landlord or Landlord's agents, employees, invitees,
licensees, servants and contractors. Tenant shall also repair all damage to the
Building and the Demised Premises caused by the moving of Tenant's fixtures,
furniture or equipment. All the aforesaid repairs shall be of quality or class
equal to the condition existing prior to the damage, ordinary wear and tear,
obsolescence and damage by casualty excepted. If Tenant fails, after ten (10)
days written notice from Landlord, to proceed with due diligence to make repairs
required to be made by Tenant under this Article 4, the same may be made by the
Landlord at the expense of Tenant, and the actual reasonable expenses thereof
incurred by Landlord shall be collectible, as additional rent within thirty (30)
days, after rendition of a bill or statement therefor. If the Demised Premises
be or become infested with vermin by reason of Tenant's actions or omissions,
Tenant shall, at its expense, cause the same to be exterminated. Tenant shall
give Landlord prompt notice of any defective condition in the Demised Premises
for which Landlord may be responsible hereunder (including but not limited to
plumbing, heating system or electrical lines located in the Demised Premises).
Notwithstanding the foregoing, Tenant's failure to give such notice to Landlord
shall not be deemed a waiver by Tenant or Tenant's rights or a discharge of
Landlord's obligations hereunder (provided Tenant gives notice of the same
within the three (3) month period immediately following the occurrence of the
defective condition). Landlord shall, at its sole cost and expense, remedy the
condition with due diligence, but at the expense of Tenant, if repairs are
necessitated by damage or injury attributable to Tenant, Tenant's servants,
agents, employees, invitees or licensees as aforesaid. There shall be no
allowance to the Tenant for a diminution of rental value and no liability on the
part of Landlord by reason of inconvenience, annoyance or injury to business
arising from Landlord, Tenant or others making or failing to make any repairs,
alterations, additions or improvements in or to any portion of the Building or
the Demised Premises or in and to the fixtures, appurtenances or equipment
thereof. The provisions of this Article 4 with respect to the making of repairs
shall not apply in the case of fire or other casualty with regard to which
Article 9 shall apply.

          Landlord agrees to substantially complete the following common area or
public portion upgrades within six (6) months from the date of execution of this
Lease:

               1.   Lobby - Periodic restoration of marble floors, wall and
                    ceiling murals; installation of a "Dignified First Class"
                    lobby kiosk directory;

                                      -2-
<PAGE>

               2.   Bathrooms - All existing bathrooms to be periodically
                    renovated.

               3.   Elevator Cabs - Remodeled "State of the Art" controls and
                    new elevator cabs.

               4.   Risers - Building will be providing a secure riser
                    management system. Riser space is available as per
                    building's rate schedule (as outlined in the Generator
                    Article of this lease). There shall be no charge for Tenant
                    to run conduit between Tenant's contiguous floors as long as
                    it is within the space occupied by Tenant, i.e. within the
                    Demised Premises; and

               5.   Upgrade Class "E" System.


          5.   Window Cleaning: Tenant will not clean nor require, permit,
suffer or allow any window in the Demised Premises to be cleaned from the
outside in violation of Section 202 of the New York State Labor Law or any other
                                           ---------------------------
applicable law or of the Rules of the Board of Standards and Appeals, or of any
other Board or body having or asserting jurisdiction.

          6.   Requirements of Law, Fire Insurance, Floor Loads: Prior to the
commencement of the lease term, if Tenant is then in possession, and at all
times thereafter, Tenant shall, at Tenant's sole cost and expense, promptly
comply with all present and future laws, orders and regulations of all state,
federal, municipal and local governments, departments, commissions and boards
and any direction of any public officer pursuant to law, and all orders, rules
and regulations of the New York Board of Fire Underwriters, or the Insurance
Services Office, or any similar body which shall impose any violation, order or
duty upon Landlord or Tenant with respect to the Demised Premises, as a direct
consequence of Tenant's specific manner of use thereof (including any Tenant
alterations), or, with respect to the Building, if as a direct consequence of
Tenant's acts or omissions in connection with its specific manner of use of the
Demised Premises or the Building (other than the use permitted under the lease).
Nothing herein shall require Tenant to make structural repairs or alterations
unless Tenant has, by its manner of use of the Demised Premises or method of
operation therein, violated any such laws, ordinances, orders, rules,
regulations or requirements with respect thereto. In no event shall Tenant be
required to make any structural repairs to the Demised Premises in order to
comply with laws, unless the necessity for same shall be due to Tenant's
negligence or willful misconduct or its specific manner of use including
Tenant's alterations. Tenant may, after securing Landlord to Landlord's
satisfaction against all damages, interest, penalties and expenses, including,
but not limited to, reasonable attorney's fees, by cash deposit or by surety
bond in an amount and in a company satisfactory to Landlord, contest and appeal
any such laws, ordinances, orders, rules, regulations or requirements provided
same is done with all reasonable promptness and provided such appeal shall not
subject Landlord to prosecution for a criminal offense, or cause the Demised
Premises or any part thereof to be condemned or vacated. Tenant shall not do or
permit any act or thing to be done in or to the Demised Premises which is
contrary to law, or which will invalidate or be in conflict with public
liability, fire or other policies of insurance at any time carried by or for the
benefit of Landlord. Tenant shall not keep anything in the Demised Premises
except as now or hereafter permitted by the Fire Department, Board of Fire
Underwriters, Fire Insurance Rating Organization and other authority having
jurisdiction, and then only in such manner and such quantity so as not to
increase the rate for fire insurance applicable to the Building, nor use the
Demised Premises in a manner which will increase the insurance rate for the
Building or any property located therein over that in effect immediately prior
to the commencement of Tenant's occupancy, following thirty (30) days notice to
Tenant, accompanied by adequate evidence of such increase in fire rates
attributable solely to Tenant's use or misuse hereunder. If by reason of such
failure to comply with the foregoing the fire insurance rate shall, at the
beginning of this lease or at any time thereafter, be higher than it otherwise
would be, then Tenant shall reimburse Landlord, as additional rent hereunder,
for that portion of all fire insurance premiums thereafter paid by Landlord
which shall have been charged because of such failure by Tenant, provided that
Landlord shall have given Tenant thirty (30) days prior written notice that such
failure would cause the rate of fire insurance for the Building to increase. In
any action or proceeding wherein Landlord and Tenant are parties, a schedule of
"make-up" or rate for the Building or Demised Premises issued by the New York
Fire Insurance Exchange or a body making fire insurance rates applicable to said
Demised Premises, shall be prima facie evidence of the facts therein stated and
of the items and changes in the fire insurance rates applicable to the Demised
Premises. Tenant shall not place a load upon any floor of the Demised Premises
exceeding the floor load per square foot area which it was designed to carry and
which is allowed by law provided, however, that Landlord shall have previously
delivered to Tenant a copy of the present Certificate of Occupancy for the
Building or otherwise notified Tenant in writing as to the permitted floor loads
of the Demised Premises. Tenant's equipment shall not exceed the floor load,
which floor load is shown on the annexed Certificate of Occupancy. Tenant agrees
that if as a result of the Tenant's use of the Demised Premises the Tenant
becomes obligated to pay for any increases in the Landlord's fire insurance
premiums pursuant to the provisions of Article 6 of this Lease and provided that
similar action or usage of other tenants in the Building have caused (or
contributed to) an increase in Landlord's fire insurance premiums, Tenant shall
only be responsible for its proportionate share of such increase.

               Landlord represents that the use permitted under Article 2 of
this Lease and equipment to be installed and/or operated by Tenant in the
Demised Premises will not invalidate (or be in

                                      -3-
<PAGE>

conflict with) any insurance policy carried by Landlord on the date of this
Lease, nor cause an increase in premium under any such insurance policy.

          7.   Subordination: This lease is subject and subordinate to all
ground or underlying leases and to all mortgages which may now or hereafter
affect such leases or the real property of which the Demised Premises form a
part thereof, and to all renewals, modifications, consolidations, replacements
and extensions of any such underlying leases and mortgages. This clause shall be
self-operative and no further instrument or subordination shall be required by
any ground or underlying lessor or by any mortgagee, affecting any lease or the
real property of which the Demised Premises are a part. In confirmation of such
subordination, Tenant shall execute promptly any certificate that Landlord may
reasonably request.

               Landlord agrees that it shall use best efforts (at no cost or
expense to Landlord) to obtain and deliver to Tenant, as to the existing
mortgage covering the real property of which the Demised Premises form a part,
and/or any renewal, modification, consolidation, replacement and extension of
the existing mortgage, non-disturbance agreements in recordable form (or such
agreement shall be contained in such mortgage or any renewal, modification,
consolidation, extension or replacement thereof) from the holder of any such
existing mortgage, providing in substance that provided Tenant shall have
entered into possession and occupancy of the Demised Premises and commenced
payment of fixed rent and additional rent hereunder, and so long as Tenant is
not in default in its obligations for the payment of fixed rent and additional
rent and in the performance of the other terms, covenants and conditions to be
performed on its part under this Lease beyond applicable notice and cure
periods, its possession of the Demised Premises will not be disturbed during the
term hereof, notwithstanding the foreclosure of any such mortgage, and Tenant
will not be named as a party defendant in any foreclosure proceedings brought
for the recovery of possession, it being hereby covenanted and agreed to by
Tenant that the holder of any existing such mortgage, or anyone claiming by,
through or under said holder shall not be: (a) liable for any act or omission
for any prior landlord (including Landlord), (b) subject to any offsets or
defenses which Tenant might have against any prior landlord (including
Landlord), (c) bound by any fixed rent or additional rent or other charges which
Tenant might have paid for more than the current month to a prior landlord
(including Landlord), or (d) bound by any modification of this Lease made
without the consent of such mortgagee.

               The inability of Landlord to obtain such agreement shall not be
deemed a default on Landlord's part of its obligations hereunder, or impose any
claim in favor of Tenant against Landlord by reason thereof, or affect the
validity of this Lease. Tenant agrees to (i) execute and deliver to such
mortgagee a nondisturbance and attornment agreement in form and substance
customarily adopted by such mortgagee and (ii) reimburse Landlord for all
reasonable expenses incurred by Landlord in connection therewith, including
legal expenses.

               Landlord agrees that it shall obtain and deliver to Tenant, as to
all future mortgages hereafter made covering the real property of which the
Demised Premises form a part, and/or any renewal, modification, consolidation,
replacement and extension of such future mortgage, non-disturbance agreements in
recordable form (or such agreement shall be contained in such future mortgage or
any renewal, modification, consolidation, extension or replacement thereof) from
the holder of any such mortgage, providing in substance that provided Tenant is
not in default in its obligations for the payment of fixed rent and additional
rent and in the performance of the other terms, covenants and conditions to be
performed on its part under this Lease beyond applicable notice and cure
periods, its possession of the Demised Premises will not be disturbed during the
term hereof, notwithstanding the foreclosure of any such mortgage, and Tenant
will not be named as a party defendant in any foreclosure proceedings brought
for the recovery of possession, it being hereby covenanted and agreed to by
Tenant that the holder of any such mortgage, or anyone claiming by, through or
under said holder shall not be:

     (a)  liable for any act or omission for any prior landlord (including
          Landlord), or

     (b)  subject to any offsets or defenses which Tenant might have against any
          prior landlord (including Landlord), or

     (c)  bound by any fixed rent or additional rent or other charges which
          Tenant might have paid for more than the current month to a prior
          landlord (including Landlord), or

     (d)  bound by any modification of this Lease made without the consent of
          such mortgagee.

          8.   Property - Loss, Damage, Reimbursement, Indemnity: Landlord
or its agents shall not be liable for any damage to property of Tenant or of
others entrusted to employees of the Building, nor for loss of or damage to any
property of Tenant by theft or otherwise, nor for any injury or damage to
persons or property resulting from any cause of whatsoever nature, unless caused
by or due to the negligence or wilful acts of Landlord, its agents, servants or
employees. Landlord or its agents shall not be liable for any damage caused by
other tenants or persons in, upon or about said Building or caused by operations
in connection of any private, public or quasi public work. If at any time any
windows of the Demised Premises are temporarily closed, darkened or bricked up
(or permanently closed, darkened or bricked up, if required by law) for any
reason whatsoever including, but not limited to Landlord's own acts, Landlord
shall not be liable

                                      -4-
<PAGE>

for any damage Tenant may sustain thereby and Tenant shall not be entitled to
any compensation therefor nor any abatement or diminution of rent nor shall the
same release Tenant from its obligations hereunder nor constitute an actual or
constructive eviction. Tenant shall indemnify and save harmless Landlord against
and from all liabilities, obligations, damages, penalties, claims, costs and
expenses for which Landlord shall not be reimbursed by insurance, including
reasonable attorney's fees, paid, suffered or incurred as a result of any breach
by Tenant, Tenant's agents, contractors, employees, invitees, or licensees, of
any covenant or condition of this lease, or the carelessness, negligence or
improper conduct of the Tenant, Tenant's agents, contractors, employees,
invitees or licensees. Landlord shall indemnify and save harmless Tenant against
and from all liabilities, obligations, damages, penalties, claims, costs and
expenses for which Tenant shall not be reimbursed by insurance, including
reasonable attorney's fees, paid, suffered or incurred as a result of any breach
by Landlord, Landlord's agents, contractors, employees, invitees, or licensees,
of any covenant or condition of this lease, or the carelessness, negligence or
improper conduct of the Tenant, Tenant's agents, contractors, employees,
invitees or licensees.

          Notwithstanding anything contained hereinabove to the contrary, each
party hereby releases the other party (which term as used in this paragraph
includes the employees, agents, shareholders, officers and directors of the
other party) from all liability whether for negligence or otherwise, in
connection with any loss covered by any insurance policies which the releasor
carries with respect to the Demised Premises or any interest or property therein
or, thereon (whether or not such insurance is required to be carried under this
Lease), but only to the extent that such loss is collected under said insurance
policies. Such release is also conditioned upon the inclusion in the policy or
policies of a provision whereby any such release shall not adversely affect said
policies or prejudice any right of the releasor to recover thereunder. Each
party agrees that its insurance policies, aforesaid, will include such a
provision so long as the same shall be obtainable without extra cost, or if
extra cost shall be charged therefor, each party shall advise the other thereof
of the amount of the extra cost, and the other party, at its election, may pay
the same, but shall not be obligated to do so.

          9.   Destruction, Fire and Other Casualty: (a) If the Demised Premises
or any part thereof shall be damaged by fire or other casualty, Tenant shall
give immediate notice thereof to Landlord and this lease shall continue in full
force and effect except as hereinafter set forth. (b) If the Demised Premises
are partially damaged or rendered partially unusable for Tenant's purposes as
permitted pursuant to Article 2 by fire or other casualty, the damages thereto
shall be repaired by and at the expense of Landlord and the rent and additional
rent, until such repair shall be substantially completed, shall be apportioned
from the day following the casualty according to the portion of the Demised
Premises which is usable, (c) If the Demised Premises are totally damaged or
rendered wholly unusable for Tenant's purposes as permitted pursuant to Article
2 by fire or other casualty, then the rent and additional rent shall be
proportionately paid up to the time of the casualty and thenceforth shall cease
until the date when the Demised Premises shall have been repaired and restored
by Landlord, subject to Landlord's right to elect not to restore the same as
hereinafter provided. (d) If the Demised Premises are rendered wholly unusable
for Tenant's purposes as permitted pursuant to Article 2 or (whether or not the
Demised Premises are damaged in whole or in part) if the Building shall be so
damaged that Landlord shall decide to demolish it or to rebuild it, then, in any
such events, Landlord may elect to terminate this lease by written notice to
Tenant, given within 90 days after such fire or casualty, specifying a date for
the expiration of the lease, which date shall not be more than 60 days after the
giving of such notice, and upon the date specified in such notice the term of
this lease shall expire as fully and completely as if such date were the date
set forth above for the termination of this lease and Tenant shall forthwith
quit, surrender and vacate the Demised Premises without prejudice however, to
Landlord's rights and remedies against Tenant under the lease provisions in
effect prior to such termination, and any rent owing shall be paid up to such
date and any payments of rent made by Tenant which were on account of any period
subsequent to such date shall be returned to Tenant. Unless Landlord shall serve
a termination notice as provided for herein, Landlord shall make the repairs and
restorations under the conditions of (b) and (c) hereof, with all reasonable
expedition, subject to reasonable delays due to adjustment of insurance claims,
labor troubles and causes beyond Landlord's control. After any such casualty,
Tenant shall cooperate with Landlord's restoration by removing from the Demised
Premises as promptly as reasonably possible, all of Tenant's salvageable
inventory and movable equipment, furniture, and other property. Tenant's
liability for rent shall resume upon the earlier to occur of (x) Tenant's
resuming full use and occupancy of the Demised Premises, or (y) twenty (20) days
after written notice from Landlord that the Demised Premises are substantially
ready for Tenant's occupancy. (e) Nothing contained hereinabove shall relieve
Tenant from liability that may exist as a result of damage from fire or other
casualty. Notwithstanding the foregoing, each party shall look first to any
insurance in its favor before making any claim against the other party for
recovery for loss or damage resulting from fire or other casualty, and to the
extent that such insurance is in force and collectible and to the extent
permitted by law, Landlord and Tenant each hereby releases and waives all right
of recovery against the other or any one claiming through or under each of them
by way of subrogation or otherwise. The foregoing release and waiver shall be in
force only if both releasors' insurance policies contain a clause providing that
such a release or waiver shall not invalidate the insurance. If, and to the
extent, that such waiver can be obtained only by the payment of additional
premiums, then the party benefitting from the waiver shall pay such premium
within ten (10) days after written demand or shall be deemed to have agreed that
the party obtaining insurance coverage shall be free of any further obligation
under the provisions hereof with respect to waiver of subrogation. Tenant
acknowledges that Landlord will not carry insurance on Tenant's furniture and or
furnishing or any fixtures or equipment, improvements, or appurtenances
removable by

                                      -5-
<PAGE>

Tenant and agrees that Landlord will not be obligated to repair any damage
thereto or replace the same, (f) Tenant hereby waives the provisions of Section
227 of the Real Property Law and agrees that the provisions of this Article
           -----------------
shall govern and control in lieu thereof.

               If the building or the Demised Premises shall be so damaged by
fire or other casualty so as to interfere substantially with the use of or
access to the Demised Premises by Tenant, or it shall have been mutually
determined by Landlord and Tenant, no later than thirty (30) days from the
occurrence of the event, that such damage cannot be repaired within four (4)
months from the date of the occurrence of the event then Tenant shall have the
right, by giving written notice to Landlord to such effect within fifteen (15)
days after it has been determined that the damage can not be restored or
repaired within the aforesaid period, to terminate this Lease and its
obligations hereunder, in which event the fixed rent and additional rent shall
be prorated to the date of the occurrence of such damage. If Tenant shall fail
to serve such notice as aforesaid, then this Lease shall continue in full force
and effect subject, however, to Landlord's right of termination as set forth in
this Article 9.

          10.  Eminent Domain: If the whole or more than fifty (50%) percent of
the Demised Premises shall be acquired or condemned by eminent domain for any
public or quasi public use or purpose, or in the event of any condemnation in
respect of the Building which renders the Demised Premises wholly untenantable,
then and in that event, the term of this lease shall cease and terminate from
the date of title vesting in such proceeding and Tenant shall have no claim for
the value of any unexpired term of said lease.

               Nothing contained in Article 10 hereof shall prohibit Tenant from
making a separate claim with the condemning authority for (a) the value of
property owned by Tenant, (b) any moving expenses incurred by Tenant as a result
of such condemnation and (c) any other separate claim which Tenant may hereafter
be permitted to make provided, however, that such separate claim shall not
reduce or adversely affect the amount of Landlord's award.

          11.  Assignment, Mortgage, Etc.: Tenant, for itself, its heirs,
distributees, executors, administrators, legal representatives, successors and
assigns, expressly covenants that it shall not assign, mortgage or encumber this
Lease, nor underlet, or suffer or permit the Demised Premises or any part
thereof to be used by others without the prior written consent of Landlord
(which consent shall not be unreasonably withheld, delayed or conditioned) in
each instance except as otherwise set forth in Article 42. Transfer of the
majority of the stock of a corporate Tenant shall be deemed an assignment of
this lease except as set forth in Article 42. If this lease be assigned, or if
the Demised Premises or any part thereof be underlet or occupied by anybody
other than Tenant, Landlord may, after default by Tenant, collect rent from the
assignee, under-tenant or occupant, and apply the net amount collected to the
rent herein reserved, but no such assignment, underletting, occupancy or
collection shall be deemed a waiver of this covenant, or the acceptance of the
assignee, under-tenant or occupant as tenant, or a release of Tenant from the
further performance by Tenant of covenants on the part of Tenant herein
contained. The consent by Landlord to an assignment or underletting shall not in
anyway be constructed to relieve Tenant from obtaining the express consent in
writing of Landlord to any further assignment or underletting.

               12.  Electric Current: See Article 46.

               13.  Access to Premises: Landlord or Landlord's agents shall
have the right (but shall not be obligated) to enter the Demised Premises in any
emergency at any time, and, at other reasonable times upon reasonable advance
notice to Tenant, to examine the same and to make such repairs, replacements and
improvements as Landlord may deem necessary and reasonably desirable to any
portion of the Building or which Landlord may elect to perform in the Demised
Premises after Tenant's failure to make repairs or perform any work which Tenant
is obligated to perform under this lease, or for the purpose of complying with
laws, regulations and other directions of governmental authorities. Except in
emergency cases, Landlord will not enter or access the sixth (6/th/) floor of
the Building and/or the mechanical areas servicing the Demised Premises without
a representative of Tenant present. Landlord shall perform any work using all
reasonable efforts to minimize interference and interruption with Tenant's
occupancy and the conduct of its business in the Demised Premises. Tenant shall
permit Landlord to use and maintain and replace pipes and conduits in and
through the Demised Premises and to erect new pipes and conduits therein
provided, that (a) such pipes and conduits are concealed in the walls, floors,
columns or ceiling of the executive and administrative portions of the Demised
Premises if practical and/or legal, (b) the work is performed at such times and
by such methods as will not unreasonably interfere with Tenant's use and
occupancy of the Demised Premises (c) damage the appearance of the Demised
Premises or (d) materially and adversely affect the layout of the Demises
Premises. Landlord at its sole cost and expense, shall promptly repair any
damage caused by any such work. Landlord may, during the progress of any work in
the Demised Premises, take all necessary materials and equipment into the
Demised Premises, provided Landlord does not unreasonably interfere with
Tenant's use and occupancy of the Demised Premises without the same constituting
an actual or constructive eviction nor shall the Tenant be entitled to any
abatement of rent while such work is in progress nor to any damages by reason of
loss or interruption of business or otherwise. Throughout the term hereof,
Landlord shall have the right to enter the Demised Premises at reasonable hours
upon reasonable advance notice to Tenant for the purpose of showing the same to
prospective purchasers or mortgagees of the Building, and upon reasonable
advance notice to Tenant during the last six (6) months of the term for the
purpose of

                                      -6-
<PAGE>

showing the same to prospective tenants and may, during said six (6) months
period, place upon the Building the usual notices "To Let" and "For Sale" which
notices Tenant shall permit to remain thereon without molestation. If Tenant is
not present to open and permit an entry into the Demised Premises, Landlord or
Landlord's agents may enter the same by master key or forcibly in an event of an
emergency only and provided reasonable care is exercised to safeguard Tenant's
property, such entry shall not render Landlord or its agents liable therefor,
nor in any event shall the obligations of Tenant hereunder be affected. If
during the last month of the term Tenant shall have removed all or substantially
all of Tenant's property therefrom, Landlord may immediately enter, alter,
renovate or redecorate the Demised Premises without limitation or abatement of
rent, or incurring liability to Tenant for any compensation and such act shall
have no effect on this lease or Tenant's obligations hereunder, except that
Tenant shall have no obligations to repair or restore any portion of the Demised
Premises which Landlord alters, decorates or renovates. Notwithstanding anything
to the contrary contained in Article 13, the Rider hereto or any other provision
contained in this Lease, Landlord acknowledges that it shall not have the right
to enter into (w) any portion of the Demised Premises designated on Exhibit A as
the "Shared Area"; (x) any other portion of the Demised Premises designated on
Exhibit A as a "Secure Area" or hereinafter designated as such by Tenant in
writing for any reason whatsoever; (y) the sixth (6/th/) floor or any part of
the Demised Premises in which a "data center" is located; and (z) any mechanical
areas servicing the Demised Premises (collectively, the "Restricted Area"),
without the prior consent of Tenant in each instance, except in the case of an
emergency.

          14.  Vault, Vault Space, Area: No Vaults, vault space or area, whether
or not enclosed or covered, not within the property line of the Building is
leased hereunder, anything contained in or indicated on any sketch, blue print
or plan, or anything contained elsewhere in this lease to the contrary
notwithstanding. Landlord makes no representation as to the location of the
property line of the Building. All vaults and vault space and all such areas not
within the property line of the Building, which Tenant may be permitted to use
and/or occupy, is to be used and/or occupied under a revocable license, and if
any such license be revoked or if the amount of such space or area be diminished
or required by any federal, state or municipal authority or public utility,
Landlord shall not be subject to any liability nor shall Tenant be entitled to
any compensation or diminution or abatement of rent, nor shall such revocation,
diminution or requisition be deemed an actual or constructive eviction. Any tax,
fee or charge of municipal authorities for such vault or area shall be paid
Tenant, if used by Tenant, whether or not specifically leased hereunder.

          15.  Occupancy: Tenant will not at any time use or occupy the Demised
Premises in violation of the Certificate of Occupancy issued for the Building.
Tenant has inspected the Demised Premises and accepts them as is, subject to any
Riders annexed hereto with respect to Landlord's Work, if any. In any event,
Landlord makes no representation as to the condition of the Demised Premises and
Tenant agrees to accept the same subject to violations, whether or not of
record. To the best of Landlord's knowledge, there are no health, safety or fire
law violations affecting the Demised Premises and that the Demised Premises will
be delivered in compliance with all local laws other than local laws whose
compliance with is conditioned upon Tenant completing its initial work. Landlord
represents and warrants to Tenant that the existing Certificate of Occupancy for
the Building is in full force and effect, and is annexed hereto and made a part
hereof as Exhibit D.

          16.  Bankruptcy: (a) Anything elsewhere in this lease to the contrary
notwithstanding, this lease may be cancelled by Landlord by sending of a written
notice to Tenant within a reasonable time after the happening of any one or more
of the following events: (1) the commencement of a case in bankruptcy or under
the laws of any state naming Tenant as the debtor, which, in the case of an
involuntary bankruptcy, is not dismissed or stayed within ninety (90) days after
the commencement thereof or (2) the making by Tenant of an assignment or any
other arrangement for the benefit of creditors under any state statute. Neither
Tenant nor any person claiming through or under Tenant, or by reason of any
statute or order of court, shall thereafter be entitled to possession of the
Demised Premises but shall forthwith quit and surrender the Demised Premises. If
this lease shall be assigned in accordance with its terms, the provisions of
this Article 16 shall be applicable only to the party then owning Tenant's
interest in this lease.

               (b)  It is stipulated and agreed that in the event of the
termination of this lease pursuant to (a) hereof, Landlord shall forthwith,
notwithstanding any other provisions of this lease to the contrary, be entitled
to recover from Tenant as and for liquidated damages an amount equal to the
difference between the rental reserved hereunder for the unexpired portion of
the term and the fair and reasonable rental value of the Demised Premises for
the same period. In the computation of such damages the difference between any
installment of rent becoming due hereunder after the date of termination and the
fair and reasonable rental value of the Demised Premises for the period for
which such installment was payable shall be discounted to the date of
termination at the rate of ten percent (10%) per annum. If the Demised Premises
or any part thereof be relet by Landlord for the unexpired term of said lease,
or any part thereof, before presentation of proof of such liquidated damages to
any court, commission or tribunal, the amount of rent reserved upon such
reletting shall be deemed to be the fair and reasonable rental value for the
part or the whole of the Demised Premises so re-let during the term of the re-
letting. Nothing herein contained shall limit or prejudice the right of the
Landlord to prove for and obtain as liquidated damages by reason of such
termination, an amount equal to the maximum allowed by any statute or rule of
law in effect at the time when, and governing the proceedings in which, such
damages are to be proved, whether or not such amount be greater, equal to, or
less than the amount of the difference referred to above.

                                      -7-

          17.  Default: A. If Tenant defaults in fulfilling any of the covenants
of this lease other than the covenants for the payment of rent or additional
rent; or if the Demised Premises becomes vacant or deserted; or if any execution
or attachment shall be issued against Tenant or any of Tenant's property
whereupon the Demised Premises shall be taken or occupied by someone other than
Tenant; or if this lease be rejected under Section 235 of Title 11 of the U.S.
Code (bankruptcy code); then, in any one or more of such events, upon Landlord
serving a written thirty (30) days notice upon Tenant specifying the nature of
said default and upon the expiration of said thirty (30) days if Tenant shall
have failed to comply with or remedy such default, or if the said default or
omission complained of shall be of a nature that the same cannot be completely
cured or remedied within said thirty (30) day period, and if Tenant shall not
have diligently commenced curing such default within such thirty (30) day
period, and shall not thereafter with reasonable diligence and in good faith,
proceed to remedy or cure such default, then Landlord may serve a written ten
(10) days' notice of cancellation of this lease upon Tenant, and upon the
expiration of said ten (10) days this lease and the term thereunder shall end
and expire as fully and completely as if the expiration of such ten (10) day
period were the day herein definitely fixed for the end and expiration of this
lease and the term thereof and Tenant shall then quit and surrender the Demised
Premises to Landlord but Tenant shall remain liable as hereinafter provided.

     B.   If the notice provided for in (1) hereof shall have been given and the
term shall expire as aforesaid; or if after ten (10) days written notice from
Landlord Tenant shall make default in the payment of any item of rent reserved
herein or any item of additional rent herein mentioned or any part of either or
in making any other payment herein required: then and in any of such events,
Landlord may dispossess Tenant by summary proceedings or otherwise, and the
legal representative of Tenant or other occupant of the Demised Premises and
remove their effects and hold the Demised Premises as if this lease had not been
made, and Tenant hereby waives the service of notice of intention to re-enter or
to institute legal proceedings to that end. If Tenant shall make default
hereunder prior to the date fixed as the commencement of any renewal or
extension of this lease, Landlord may cancel and terminate such renewal or
extension agreement by written notice.

          18.  Remedies of Landlord and Waiver of Redemption: In case of any
such default, expiration and/or dispossess by summary proceedings or otherwise,
(a) the rent, and additional rent, shall become due thereupon and be paid up to
the time of such re-entry, dispossess and/or expiration, (b) Landlord may re-let
the Demised Premises or any part or parts thereof, in the name of Landlord, for
a term or terms, which may at Landlord's option be less than or exceed the
period which would otherwise have constituted the balance of the term of this
lease and may grant then customary and reasonable concessions or free rent or
charge a higher rental than that in this lease, (c) Tenant or the legal
representatives of Tenant shall also pay Landlord as liquidated damages for the
failure of Tenant to observe and perform said Tenant's covenants herein
contained, any deficiency between the rent hereby reserved and or covenanted to
be paid and the net amount, if any, of the rents collected on account of the
subsequent lease or leases of the Demised Premises for each month of the period
which would otherwise have constituted the balance of the term of this lease.
The failure of Landlord to re-let the Demised Premises or any part or parts
thereof shall not release or affect Tenant's liability for damages hereunder,
subject to Landlord's obligations to mitigate damages under New York law, if
any. Landlord shall, if required by law, use good faith efforts to (i) relet the
Demised Premises at fair market rents and (ii) upon sub-reletting, to collect
all rents due thereunder and to otherwise mitigate its damages hereunder. In
computing such liquidated damages there shall be added to the said deficiency
such reasonable expenses as Landlord may incur in connection with re-letting,
such as legal expenses, attorneys' fees, brokerage, advertising and for keeping
the Demised Premises in good order or for preparing the same for subject to
Landlord's re-letting. Any such liquidated damages shall be paid in monthly
installments by Tenant on the rent day specified in this lease and any suit
brought to collect the amount of the deficiency for any month shall not
prejudice in any way the rights of Landlord to collect the deficiency for any
subsequent month by a similar proceeding. Landlord, in putting the Demised
Premises in good order or preparing the same for re-rental may, at Landlord's
option, make such alterations, repairs, replacements, and/or decorations in the
Demised Premises as Landlord, in Landlord's sole reasonable judgment, considers
advisable and necessary for the purpose of re-letting the Demised Premises, and
the making of such alterations, repairs, replacements, and/or decorations shall
not operate or be construed to release Tenant from liability hereunder as
aforesaid. Landlord shall in no event be liable in any way whatsoever for
failure to re-let the Demised Premises, or in the event that the Demised
Premises are re-let, for failure to collect the rent thereof under such re-
letting subject to Landlord's obligation to mitigate damages, if any, and in no
event shall Tenant be entitled to receive any excess, if any, of such net rents
collected over the sums payable by Tenant to Landlord hereunder. In the event of
a breach or threatened breach by Tenant of any of the covenants or provisions
hereof, Landlord and Tenant shall have the right of injunction and the right to
invoke any remedy allowed at law or in equity as if re-entry, summary
proceedings and other remedies were not herein provided for. Mention in this
lease of any particular remedy, shall not preclude Landlord or Tenant from any
other remedy, in law or in equity. Tenant hereby expressly waives any and all
rights of redemption granted by or under any present or future laws in the event
of Tenant being evicted or dispossessed for any cause, or in the event of
Landlord obtaining possession of Demised Premises, by reason of the violation by
Tenant of any of the covenants and conditions of this lease, or otherwise.

          19.  Fees and Expenses: If Tenant shall default beyond applicable
notice and cure periods in the observance or performance of any term or covenant
on Tenants part to be observed or

                                      -8-
<PAGE>

performed under or by virtue of any of the terms or provisions in any Article of
this lease, then, unless otherwise provided elsewhere in this lease, Landlord
may immediately in the case of an emergency or at any time after ten (10) days
written notice perform the obligations of Tenant hereunder. If Landlord, in
connection with the foregoing or in connection with any default by Tenant in the
covenant to pay rent hereunder, makes any expenditures or incurs any reasonable
obligations for the payment of money, including but not limited to attorney's
fees, in instituting, prosecuting or defending any action or proceedings and
Landlord prevails, then Tenant will reimburse Landlord for such sums so paid or
obligations incurred with interest and costs. The foregoing expenses incurred by
reason of Tenant's default shall be deemed to be additional rent hereunder and
shall be paid by Tenant to Landlord within twenty (20) days after rendition of
any bill or statement to Tenant therefor. If Tenant's lease term shall have
expired at the time of making of such expenditures or incurring of such
obligations, such sums shall be recoverable by Landlord as damages.

          20.  Building Alterations and Management: Subject to the provisions of
Article 13 above, and more particularly, the restrictions set forth therein in
respect of Restricted Areas, Landlord shall have the right at any time, upon
reasonable notice to Tenant, without the same constituting an eviction and
without incurring liability to Tenant therefor to run pipes and conduits through
the Demised Premises and other building areas, make other repairs and to change
the arrangement and or location of public entrances, passageways, doors,
doorways, corridors, elevators, stairs, toilets or other public parts of the
Building and to change the name, number or designation by which the Building may
be known, provided that any such changes do not in no more than a de-minimis
manner change the location and size of the Demised Premises, or in no more than
a de-minimis manner interfere with ingress and egress to and from the Demised
Premises or Tenant's use and occupancy thereof. Landlord shall endeavor to
perform such repairs and relocations in the walls, columns and ceilings or
below finished surfaces. Notwithstanding anything to the contrary contained in
this Lease, Landlord shall not make any repairs to the Restricted Areas without
prior written approval of Tenant's engineers, except in the case of an
emergency. There shall be no allowance to Tenant for diminution of rental value
and no liability on the part of Landlord by reason of inconvenience, annoyance
or injury to business arising from Landlord or other Tenants making any repairs
in the Building or any such alterations, additions and improvements provided
such work does not in more than a deminimus manner interfere with Tenant's use
and occupancy of the Demised Premises. Furthermore, Tenant shall not have any
claim against Landlord by reason of Landlord's imposition of any controls of the
manner of access to the Building by Tenant's invitees as the Landlord may deem
necessary for the security of the Building and its occupants.

          21.  No Representations by Landlord: Neither Landlord nor Landlord's
agents have made any representations or promises with respect to the physical
condition of the Building (except for the completion of Landlord's Work, as
hereinafter defined), the land upon which it is erected or the Demised Premises,
the rents, leases, expenses of operation or any other matter or thing affecting
or related to the Demised Premises or the Building except as herein expressly
set forth and no rights, easements or licenses are acquired by Tenant by
implication or otherwise except as expressly set forth in the provisions of this
lease. Tenant has inspected the Building and the Demised Premises and is
thoroughly acquainted with their condition and agrees to take the same "as is"
on the date possession is tendered and acknowledges that the taking of
possession of the Demised Premises by Tenant shall be conclusive evidence that
the said Demised Premises and the Building of which the same form a part were in
good and satisfactory condition at the time such possession was so taken. All
understandings and agreements heretofore made between the parties hereto are
merged in this contract, which alone fully and completely expresses the
agreement between Landlord and Tenant and any executory agreement hereafter made
shall be ineffective to change, modify, discharge or effect an abandonment of it
in whole or in part, unless such executory agreement is in writing and signed by
the party against whom enforcement of the change, modification, discharge or
abandonment is sought.

          22.  End of Term: Upon the expiration or sooner termination of the
term of this lease, Tenant shall quit and surrender to Landlord the Demised
Premises, broom clean, in good order and condition, ordinary wear and damages
which Tenant is not required to repair as provided elsewhere in this lease
excepted, and Tenant shall remove all its property from the Demised Premises.
Tenant's obligation to observe or perform its covenant shall survive the
expiration or other termination of its lease. If the last day of the term of
this Lease or any renewal thereof, falls on Sunday, this lease shall expire at
noon on the preceding Saturday unless it be a legal holiday in which case it
shall expire at noon on the preceding business day.

          23.  Quiet Enjoyment: Landlord covenants and agrees with Tenant that
upon Tenant paying the rent and additional rent and observing and performing all
the terms, covenants and conditions, on Tenant's part to be observed and
performed, Tenant may peaceably and quietly enjoy the Demised Premises hereby
demised, subject, nevertheless, to the terms and conditions of this lease.

          24.  Failure to Give Possession: If Landlord is unable to give
possession of the Demised Premises on the date of the commencement of the term
hereof, because of the holding-over or retention of possession of any tenant,
undertenant or occupants, or if Landlord has not completed any work required to
be performed by Landlord, or for any other reason, Landlord shall not be subject
to any liability, except as provided below, for failure to give possession on
said date and the validity of the lease shall not be

                                      -9-
<PAGE>

impaired under such circumstances, nor shall the same be construed in any manner
to extend the term of this lease, but the rent payable hereunder shall be
abated until after Landlord shall have given Tenant notice that the Demised
Premises are substantially ready for Tenant's occupancy. If permission is given
to Tenant to enter into the possession of the Demised Premises or to occupy any
space in the Building other than the Demised Premises prior to the date
specified as the commencement of the term of this lease, Tenant covenants and
agrees that such occupancy shall be deemed to be under all the terms, covenants,
conditions and provisions of this lease, except as to the covenant to pay rent.
The provisions of this Article are intended to constitute "an express provision
to the contrary" within the meaning of Section 223-a of the New York Real
                                                            -------------
Property Law.
------------

               Notwithstanding the foregoing provisions of this Lease, in the
event that Landlord fails to deliver possession of the Demised Premises with
Landlord's Work substantially complete on or prior to the date which is forty
five (45) days from the date of lease execution, Tenant shall be entitled to an
additional day for day abatement of fixed rent for each day past forty five (45)
days that Landlord's Work is not substantially complete. Tenant may have access
to the Demised Premises during performance of Landlord's Work and each party and
their contractors shall cooperate with each other so as to minimize interference
with Landlord's Work and Tenant's Work respectively.

               Notwithstanding the foregoing provisions of this Lease, in the
event that Landlord fails to deliver possession of the Demised Premises with
Landlord's Work substantially complete (as defined below) on or prior to the
date which is six (6) months from the date of execution of this Lease, Tenant
shall have the right to terminate this Lease within the following ten (10)
business days by giving notice thereof to Landlord. Upon receipt of such notice
by Landlord, all liability between the parties hereto shall be extinguished,
except that Landlord shall return to Tenant any monies deposited with Landlord
pursuant to this Lease. The foregoing right of termination shall be Tenant's
exclusive remedy with respect to the failure to deliver possession.

          25.  No Waiver: The failure of Landlord or Tenant to seek redress for
violation of, or to insist upon the strict performance of any covenant or
condition of this lease or of any of the Rules or Regulations, set forth or
hereafter adopted by Landlord, shall not prevent a subsequent act which would
have originally constituted a violation from having all the force and effect of
an original violation. The receipt by Landlord or payment by Tenant of rent with
knowledge of the breach of any covenant of this lease shall not be deemed a
waiver of such breach and no provision of this lease shall be deemed to have
been waived by Landlord unless such waiver be in writing signed by the party
against whom such waiver is sought to be enforced. No payment by Tenant or
receipt by Landlord of a lesser amount than the monthly rent herein stipulated
shall be deemed to be other than on account of the earliest stipulated rent, nor
shall any endorsement or statement of any check, any letter accompanying any
check or payment of rent be deemed an accord and satisfaction and Landlord may
accept such check or payment without prejudice to Landlord's right to recover
the balance of such rent or pursue any other remedy in this lease provided. All
checks tendered to Landlord as and for the rent of the Demised Premises shall be
deemed payments for the account of Tenant. Acceptance by Landlord of rent from
anyone other than Tenant shall not be deemed to operate as an attornment to
Landlord by the payor of such rent or as a consent by Landlord to an assignment
or subletting by Tenant of the Demised Premises to such payor, or as a
modification of the provisions of this lease. No act or thing done by Landlord
or Landlord's agents during the term hereby demised shall be deemed an
acceptance of a surrender of said Demised Premises and no agreement to accept
such surrender shall be valid unless in writing signed by Landlord. No employee
of Landlord or Landlord's agent shall have any power to accept the keys of said
Demised Premises prior to termination of the lease and the delivery of keys to
any such agent or employee shall not operate as a termination of the lease or a
surrender of the Demised Premises.

          26.  Waiver of Trial by Jury: It is mutually agreed by and between
Landlord and Tenant that the respective parties hereto shall and they hereby do
waive trial by jury in any action, proceeding or counterclaim brought by either
of the parties hereto against the other (except for personal injury or property
damage) on any matters whatsoever arising out of or in any way connected with
this lease, the relationship of Landlord and Tenant, Tenant's use of or
occupancy of the Demised Premises, and any emergency statutory or any other
statutory remedy. It is further mutually agreed that in the event Landlord
commences any summary proceeding for possession of the Demised Premises, Tenant
will not interpose any counterclaim of whatever nature or description in any
such proceeding except for mandatory counterclaims which would otherwise be
waived.

          27.  Inability to Perform: Except as otherwise expressly set forth in
the Lease, this Lease and the obligation of Tenant to pay rent hereunder and
perform all of the other covenants and agreements hereunder on part of Tenant to
be performed shall in no manner be affected, impaired or excused because
Landlord is unable to fulfill any of its obligations under this lease or to
supply or is delayed in supplying any service expressly or impliedly to be
supplied or is unable to make, or is delayed in making any repair, additions,
alterations or decorations or is unable to supply or is delayed in supplying any
equipment or fixtures if Landlord is prevented or delayed from so doing by
reason of strike or labor troubles or any cause whatsoever beyond Landlord's
reasonable control including, but not limited to, government preemption in
connection with a National Emergency or by reason of any rule, order or
regulation of any department or

                                      -10-
<PAGE>

subdivision thereof of any government agency or by reason of the condition of
supply and demand which have been or are affected by war or other emergency.

               Notwithstanding anything contained in this Lease to the contrary,
if due to any work or installation performed by Landlord under the Lease or
failure by Landlord to perform its obligations under the Lease, (i) Tenant shall
be unable for at least seven (7) consecutive business days to operate its
business in the Demised Premises in substantially the same manner as such
business was operated prior to the performance of such work or installation or
such failure, and (ii) such interruption shall occur during business hours, the
Fixed Rent and the Additional Rent shall be reduced on a per diem basis in the
proportion in which the area of the part of the Demised Premises which is
unusable bears to the total area of the Demised Premises for each day subsequent
to the aforesaid seven (7) consecutive business day period that such portion of
the Demised Premises remains unusable.

          28.  Notices: Except as otherwise expressly provided in this Lease or
by any Legal Requirement, every notice, demand, consent, approval, request or
other communication (collectively, "notices") which may be or is required to be
given under this Lease or by law shall be in writing and shall be sent by United
States certified or registered mail, postage prepaid, return receipt requested

Regulations then in effect.


     B.   Cleaning Services
          -----------------

          (i)   Provided Tenant shall keep the Demised Premises in good order,
Landlord, at Landlord's expense, shall cause the executive and administrative
portions of the Demised premises only and the common areas of the fifth (5/th/)
floor of the Building to be cleaned. Tenant shall pay to Landlord within twenty
(20) days after receipt of a bill therefor, Landlord's charges for cleaning work
in the executive and administrative portions of the Demised Premises or the
Building required because of (i) misuse or neglect on the part of Tenant or its
employees or visitors, (ii) use of portions of the executive and administrative
portions of the Demised Premises for preparation, serving, or consumption of
food or beverages, reproducing operations, private lavatories or toilets or
other special purposes requiring greater or more difficult cleaning work than
office areas, (iii) interior partitioning glass surfaces, (iv) non-Building
standard materials or finishes installed by Tenant or at its request. Landlord
and/or its cleaning contractor and their employees shall have after hours access
to the executive and administrative portions of the Demised Premises and the use
of Tenant's light, power and water in the executive and administrative portions
of the Demised Premises as may be reasonably required for the purpose of
cleaning the executive and administrative portions of the Demised Premises.
Landlord and/or its cleaning contractor and its employees shall comply with
Tenant's security requirements with respect to the Demised Premises of which
Tenant shall notify Landlord from time to time.

          (ii)  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 Landlord, and

and, in addition, whenever there shall be evidence of any infestation.

          (iii) Only Landlord or any one or more persons, firms or corporations
authorized in writing by Landlord shall be permitted to act as maintenance

absolute discretion, at any time and from time to time, the hours during which
and regulations under which such services are to be furnished. Landlord
expressly reserves the right to act as or to designate, at any time and from
time to time, an exclusive contractor for all or any one or more of such
services, provided that the quality thereof and the charges therefor are
reasonably comparable to that of other contractors, and Landlord expressly
reserves the right to exclude from the Building any person, firm or corporation
attempting to furnish any of such services.

shall pay for water consumed as shown on said meter as additional rent within
twenty (20) days after receipt of a bill therefor.

     D.   Heat. See Article 54.
          ----

     E.   Subject to the abatement provisions contained in the last paragraph of
Article 27 hereof, Landlord reserves the right, without same constituting an

diminution of fixed rent and/or additional rent, to temporarily stop services of
the heating, elevators, plumbing, air-conditioning, power systems or cleaning or
other services, if any, when necessary by reason of accident or for repairs,
alterations, replacements or improvements necessary or desirable in the judgment
of Landlord for as long as may be reasonably required by reason thereof. If the
Building of which the Demised Premises are a part supplies manually-operated
elevator service, Landlord at any time may substitute automatic-control elevator
service and upon ten days' written notice to Tenant, proceed with alterations
necessary therefor without in any manner affecting this lease or the obligation
of Tenant hereunder. The same shall be done with a minimum of inconvenience to
Tenant and Landlord shall pursue the alteration with due diligence.

          30.  Captions: The Captions are inserted only as a matter of
convenience and for reference and in no way define, limit or describe the scope
of this lease nor the intent of any provision thereof.

          31.  Definitions: The term "Landlord" as used in this lease means only
the Landlord of the fee or of the leasehold of the Building, or the mortgagee in
possession, for the time being of the land and Building (or the Landlord of a
lease of the Building or of the land and Building) of which the Demised Premises
form a part, so that in the event of any sale or sales of said land and Building
or of said lease, or in the event of a lease of said Building, or of the land
and Building, Landlord shall be and hereby is entirely freed and relieved of all
covenants and obligations of Landlord hereunder accruing after the effective
date of such sale, and it shall be deemed and construed without further
agreement between the parties or their successors in interest, or between the
parties and the purchaser, at any such sale, of the said lessee of the Building,
or of the land and Building, that the purchaser or the lessee of the Building
has assumed and agreed to carry out any and all covenants and obligations of
Landlord hereunder. Notwithstanding the provisions of this Article

                                      -12-
<PAGE>

31 or of Article 34, no sale, assignment or transfer by Landlord of Tenant's
security deposit (in connection with the sale, transfer or assignment by
Landlord of its rights and obligations under this Lease and/or in the Building)
shall operate to release Landlord from its responsibility and liability to
Tenant for said security deposit, unless and until the party to whom such
security deposit has been assigned or transferred has acknowledged to Tenant its
receipt of such security deposit, and has assumed all of the obligations of
Landlord with respect thereto. The words "re-enter" and "re-entry" as used in
this lease are not restricted to their technical legal meaning. The term
"business days" as used in this lease, shall exclude Saturdays, Sundays and all
days observed by term State or Federal Government as legal holidays and those
designated as holidays by the applicable Building service union employees
service contract or by the applicable Operating Engineers contract with respect
to HVAC service.

          32.  Estoppel Certificate: Tenant and Landlord shall execute,
acknowledge and deliver to each other, within ten (10) business days after
Landlord's or Tenant's request, a certificate stating: (a) that this lease is
unmodified and in full force and effect (or, if there have been modifications,
that this lease is in full force and effect, as modified, and identifying the
modifications); (b) the commencement and expiration dates of the term of this
lease; (c) the dates through which fixed rent and additional rent have been
paid; (d) whether or not there is any existing default by Landlord or Tenant
with respect to which a notice of default has been delivered, and if there is
any such default, specifying the nature and extent thereof; (e) that this lease
is subordinate to any existing or future mortgage placed by Landlord on the
Building; and (f) whether or not there are any setoffs, defenses or
counterclaims against the enforcement of any of the agreements, terms, covenants
or conditions of this lease to be paid, complied with or performed by Tenant.
Any such certificate may be relied upon by Landlord and any mortgagee, purchaser
or other person with whom Landlord may deal. In the event that Tenant fails to
deliver the certificate required under this Article 32, same shall be deemed a
default hereunder. Tenant's only liability under this Article 32 is to be
estopped from any claim contrary to the certificate executed therein.

          33.  Rules and Regulations: Tenant and Tenant's servants, employees,
agents, visitors, and licensees shall observe faithfully, and comply strictly
with, the Rules and Regulations annexed hereto and made a part hereof as Exhibit
C and such other and further reasonable Rules and Regulations as Landlord or
Landlord's agents may from time to time adopt, provided, however, that Landlord
shall give Tenant at least ten business (10) days prior written notice of any
such other or further Rules or Regulations. In case Tenant disputes the
reasonableness of any additional Rule or Regulation hereafter made or adopted by
Landlord or Landlord's agents, the parties hereto agree to submit the question
of the reasonableness of such Rule or Regulation for decision to the New York
office of the American Arbitration Association, whose determination shall be
final and conclusive upon the parties hereto. The right to dispute the
reasonableness of any additional Rule or Regulation upon Tenant's part shall be
deemed waived unless the same shall be asserted by service of a notice, in
writing upon Landlord within fifteen (15) days after the giving of notice
thereof. Landlord shall apply all Rules and Regulations without discrimination
against or among any tenants of the Building. Moreover, the terms, covenants,
conditions and provisions of this Lease shall govern in the event of any
conflict or inconsistency between this Lease and any Rules and Regulations.

          34.  Security. Tenant shall, upon execution of this lease, deposit
with Landlord the sum of FIVE HUNDRED THOUSAND AND 00/100 ($500,000.00) DOLLARS
security for the faithful performance and observance by Tenant of the terms,
provisions and conditions of this lease; it is agreed that in the event Tenant
defaults in respect of any of the terms, provisions and conditions of this
lease, including, but not limited to, the payment of rent and additional rent,
and fails to cure the same within any applicable grace and/or notice periods,
then, Landlord may use, apply or retain the whole or any part of the security so
deposited to the extent required for the payment of any rent and additional rent
or any other sum as to which tenant is in default or for any sum which Landlord
may expend or may be required to expend by reason of Tenant's default in respect
of any of the terms, covenants and conditions of this lease, including but not
limited to, any damages or deficiency in the re-letting of the Demised Premises,
whether such damages or deficiency accrued before or after summary proceedings
or other re-entry by Landlord. In the event that Tenant shall fully and
faithfully comply with all of the terms, provisions, covenants and conditions of
this lease, the security shall be promptly returned to Tenant. In the event of a
sale of the land and Building or leasing of the Building, of which the Demised
Premises form a part, Landlord shall have the right to transfer the security to
the vandee or lessee and Landlord shall thereupon be released by Tenant from all
liability for the return of such security; and Tenant agrees to look to the new
Landlord solely for the return of said security, and it is agreed that the
provisions hereof shall apply to every transfer or assignment made of the
security to a new Landlord. Tenant further covenants that it will not assign or
encumber or attempt to assign or encumber the monies deposited herein as
security and that neither Landlord nor its successors or assigns shall be bound
by any such assignment, encumbrance, attempted assignment or attempted
encumbrance.

          In lieu of the cash security provided for in Article 34 hereof, Tenant
may deliver to Landlord, as security pursuant to said Article 34, an
irrevocable, clean, "Evergreen" commercial letter of credit in the amount of
$500,000.00 (the "Letter"), issued by a bank which is authorized by the State of
New York or has a branch office or corresponding bank which enables Landlord to
draw upon the Letter in the State of New York and which shall permit Landlord
(a) to draw thereon up to the full amount of the credit evidenced thereby in the
event of any default by Tenant in the terms, provisions, covenants or conditions
of this Lease beyond any applicable notice and cure periods or (b) to draw the
full amount thereof to be held as cash security

                                      -13-
<PAGE>

pursuant to Article 34 hereof if for any reason the Letter is not renewed within
forty-five (45) days prior to its expiration date. The Letter (and each renewal
thereof) shall (i) be for a term of not less than one (1) year (except that the
last Letter shall be for a term expiring forty-five (45) days after the
Expiration Date), (ii) expressly provide for the issuing bank to notify Landlord
in writing not less than forty-five (45) days prior to its expiration as to its
renewal or non-renewal, as the case may be, and (iii) if not so renewed each
year (or later period of expiration) shall be immediately available for Landlord
to draw up to the full amount of such credit (to be held as cash security
pursuant to said Article 34). Not less than forty-five (45) days prior to the
expiration date of each Letter (and every renewal thereof), Tenant shall deliver
to Landlord a renewal or new Letter subject to all of the conditions aforesaid,
all to the intent and purposes, that a Letter in the sum of $500,000.00 shall be
in effect for the remainder of the term of this Lease.

          After the third (3/rd/) year of the term of the Lease, Landlord and
Tenant will seek to mutually agree to a reduction in the Security if Tenant
effectuates a public offering of its stock and materially increases its net
worth and meets other reasonable qualifications as Landlord may reasonably
request.

          35.  Adjacent Excavation - Shoring: If an excavation shall be made
upon land adjacent to the Demised Premises, or shall be authorized to be made,
Tenant shall afford to the person causing or authorized to cause such
excavation, provided, that such person compiles with all applicable requirements
of law, a license to enter upon the demises Demised Premises for the purpose of
doing such work as said person shall deem necessary to preserve the wall or the
Building of which Demised premises form a part from injury or damage and to
support the same by proper foundations without any claim for damages or
indemnity against Landlord, or diminution or abatement of rent.

          36.  Successors and Assigns: The covenants, conditions and agreements
contained in this lease shall bind and inure to the benefit of Landlord and
Tenant and their respective heirs, distributees, executors, administrators,
successors, and except as otherwise provided in this lease, their assigns.

     -------------------------

     If and to the extent that any of the provisions of this Rider conflict or
are otherwise inconsistent with any of the preceding printed provisions of this
Lease, or of the Rules and Regulations attached to this Lease, whether or not
such inconsistency is expressly noted in this Rider, the provisions of this
Rider shall prevail, and in case of inconsistency with said Rules and
Regulations, the Rider shall govern and control.

38.  ADDITIONAL DEFINITION
     ---------------------

     For the purposes of this Lease and all agreements supplemental to this
Lease, and all communications with respect thereto, unless the context otherwise
requires:

     1.   The term "fixed rent' or "Fixed Rent" shall mean rent at the annual
rental rate or rates provided for in Schedule B annexed hereto and made a part
hereof,

     2.   The term "additional rent" shall mean all sums of money, other than
fixed rent and which become due and payable from Tenant to Landlord hereunder,
and Landlord shall have the same remedies therefor as for a default in payment
of fixed rent.

     3.   The term "rent" and "rents" shall mean and include fixed rent and/or
additional rent hereunder.

     4.   The terms "Commencement Date" shall mean the date of substantial
completion of Landlord's Work and the "Expiration Date" shall mean the Jest last
of 187th calendar month following the Commencement Date.

     5.   The term "Lease Year" shall mean the twelve (12) month period
commencing on the Commencement Date and each successive twelve (12) month period
thereafter.

     6.   The term "Superior Lessee" or "Superior Mortgagee" shall mean any
party then holding a ground lease or mortgage encumbering the land and/or
Building.

     7.   The term "Rent Commencement Date" shall mean the date which is seven
(7) months following the Commencement Date, but Tenant shall receive an
additional fixed rent credit pursuant to Article 41.

     8.   The term "Substantial Completion" or "Substantially Complete" shall
mean the date when Landlord's Work then remaining to be done, if any, consists
of minor "punch list items" and shall have reached that stage of completion such
that Tenant could either use or occupy the Demised Premises or Tenant could then
proceed to complete Tenant's Work without interference in mere than a deminimus
manner by reason of those items still required to complete Landlord's Work as
reasonably determined by Tenant's architect. Further, the taking of possession
of the Demised Premises or any portion or portions thereof by Tenant following
Tenant's receipt of notice from Landlord of substantial completion of Landlord's
Work in respect thereof, or otherwise, shall be conclusive evidence that
substantial completion was, in fact, achieved, but Tenant shall have thirty (30)
days after Tenant's receipt of Landlord's notice of substantial completion to
give Landlord notice of any "punch list" items remaining to be completed, in
which event such "punch list items" shall be completed within forty-five (45)
days of Tenants notice of the existence of such items.

39.  ESCALATION FOR INCREASE IN REAL ESTATE TAXES:
     --------------------------------------------

     A.   As used herein:

          1.   "Taxes" shall mean real estate taxes payable (adjusted after
protest or litigation, if any) for any part of the term of this lease, on the
Building and/or the land (the "Land"), (i) any taxes which shall be levied in
lieu of any such taxes or which shall be levied on the gross rentals of the
Building and/or the Land, (ii) any special assessments against the Building
and/or the Land which shall be required to be paid during the fiscal year in
respect to which taxes are being determined, and (iii) the reasonable expense of
contesting the amount or validity of any such taxes, charges or assessments,
such reasonable expense to be applicable

                                      -16-
<PAGE>

to the period of the item contested; but "Taxes" shall not include (a) any
interest or penalties incurred by Landlord solely as a result of Landlord's late
payment of Taxes, (b) any assessments, bonds or other fees in connection with
the remodeling or renovation of the Building, or (c) any franchise, estate,
succession, unincorporated business, income or inheritance taxes.

          2.   "Tax Year" shall mean each period of twelve (12) months,
commencing on the first day of July of each such period, in which occurs any
part of the term of this Lease or such other period of twelve(12) months
occurring during the term of this Lease as hereafter may be duly adopted as the
fiscal year for real estate tax purposes of the City of New York.

          3.   "Base Tax" shall mean the Taxes for the 1999 calendar year i.e.,
the sum of Taxes payable for the second half 1998/1999 fiscal tax year and first
half 1999/2000 fiscal tax year (the "Base Tax Year"),

          4.   "Tenant's proportionate Share' shall mean 7.10%. If at any time
additional floors and rentable area shall be added to the Building, Tenant's
Proportionate Share shall be ratably reduced upon such addition.

          5.   "Landlord's Statement" shall mean any instrument containing a
computation of additional rent due pursuant to the provisions of this Article 39
furnished by Landlord to Tenant.

     B.   If the Taxes far any Tax Year shall be greater than the Base Tax, then
Tenant shall pay as additional rent for such Tax Year, a sum equal to Tenant's
Proportionate Share of the amount by which the Taxes for such Tax Year are
greater than the Base Tax (which amount is hereinafter called the "Tax
Payment"). If the Rent Commencement Date or the Expiration Date shall occur on a
date other than July 1 or June 30 respectively, any additional rent due under
this Article 39 for the Tax Year in which the Rent Commencement Date or
Expiration Date shall occur shall be apportioned in that percentage which the
number of days in the period from the Rent Commencement Date to June 30 or from
July 1 to the Expiration Date, as the case may be, both inclusive, shall bear to
the total number of days in such Tax Year. Tenant's obligation to pay such
additional rent and Landlord's obligation to refund pursuant to Paragraph C
below, as the case may be, shall survive the termination of this Lease. If the
Taxes for any Tax Year subsequent to the Base Tax Year, or an installment
thereof, shall be reduced before such Taxes or such installment shall be paid,
the amount of Landlord's reasonable costs and expenses of obtaining such
reduction (but not exceeding the amount of such reduction) shall be added to and
be deemed part of the Taxes for such Tax Year. Payment of additional rent for
any Tax Payment due from Tenant shall be made as and subject to the conditions
hereinafter provided in this Article.

     C.   Only Landlord shall be eligible to Institute proceedings to contest
the Taxes or reduce the assessed valuation of the Land and Building. Landlord
shall be under no obligation to contest the Taxes or the assessed valuation of
the Land and the Building for any Tax Year and may settle any such contest on
such terms as Landlord in its reasonable judgment considers proper. If Landlord
shall receive a refund for any Tax Year for which a Tax Payment shall have been
made by Tenant pursuant to Paragraph B above, Landlord shall pay to Tenant,
Tenant's Proportionate Share of such refund amount within ten (10) business days
after Landlord's receipt thereof, Tenant's Proportionate Share of such refund
(including experts' and attorneys' fees) of obtaining such refund. If the
assessment for the Base Tax Year shall be reduced from the comparative statement
(as provided in Paragraph D below) to Tenant with respect to a Tax Year, the
amount of the Tax Payment shall be adjusted in accordance with such change and
Tenant, on Landlord's demand, shall pay any increase in additional rent
resulting from such adjustment.

     D.   Landlord shall furnish to Tenant, prior to the commencement of any Tax
Year, a Landlord's Statement setting forth Landlord's estimate of Tenant's Tax
Payment, which shall include a reasonably detailed calculation of Tenant's Tax
Payment together with a copy of the real estate tax bill for the Building in
respect of such Tax Year ("Tenant's Estimated Tax Payment"). Tenant shall pay to
Landlord on the first day of each month during such Tax Year an amount equal to
one-twelfth (1/12th) of Tenant's Estimated Tax Payment for such Tax Year. If,
however, Landlord shall furnish any such statement for a Tax year subsequent to
the commencement thereof, then (i) until the first day of the month following
the month in which such statement is furnished to Tenant, Tenant shall pay to
Landlord on the first day of each month an amount equal to the monthly sum
payable by Tenant to Landlord under this Paragraph in respect of the last month
of the immediately preceding Tax year; (ii) promptly after such statement is
furnished to Tenant, Landlord shall give notice to Tenant stating whether the
installments of the Tax Payment previously made for such Tax Year were greater
or less than the installments of the Tax Payment to be made for such Tax Year in
accordance with such statement, and (a) if there shall be a deficiency, Tenant
shall pay the amount thereof within fifteen (15) days after demand therefor, or
(b) if there shall have been an overpayment, Landlord shall promptly either
refund to Tenant the amount thereof within fifteen (15) days after Tenant's
receipt of such notice, or permit Tenant to credit the amount thereof against
subsequent payments under this Article; and (iii) on the first day of the month
following the month in which such statement is furnished to Tenant, and monthly
thereafter throughout the remainder of such Tax Year, Tenant shall pay to
Landlord an amount equal to one-twelfth (1/12th) of the Tax Payment shown on
such statement.

     E.   Tenant shall have the right to request that Landlord deliver a copy of
the real estate tax bill for the Building in respect of any Tax Year.

     F.   Landlord's failure during the lease term to prepare and deliver any
Landlord's Statement, or Landlord's failure to make a demand under this Article
or under any other provision of this Lease shall not in any way waive Landlord's
right to collect any such amounts due hereunder (provided such Landlord's
Statement shall be delivered within twelve (12) months after the expiration of
the Tax Year to which it is applicable). Tenant's liability for the additional
rent due under this Article shall survive the expiration or sooner termination
of this Lease.

     G.   In no event shall any adjustment of Tax Payments hereunder result in a
decrease in the fixed rent or additional rent payable pursuant to any other
provision of the lease, it being agreed that the payment of additional rent
under this Article 39 is an obligation supplemental to Tenant's obligation to
pay fixed rent.

40.  INTENTIONALLY OMITTED.

41   FREE RENT:
     ----------

     Provided Tenant is not in default under the terms, covenants and conditions
of this lease beyond applicable grace, notice and cure periods, Tenant shall
have the right to use and occupy the Demised Premises free of fixed rent for the
first seven (7) months following the Commencement Date, and Tenant shall receive
a monthly fixed rent credit of TWENTY-SEVEN THOUSAND SEVEN HUNDRED SEVENTY EIGHT
AND 78/100 ($27,778.78) DOLLARS per month during months 13 through 48 of the
Term of this Lease; except that Tenant shall pay to Landlord all sums due under
Article 46 hereof representing reimbursement to Landlord for the furnishing to
Tenant of electric current during said periods. Except for the free fixed rent
allowance as herein provided, Tenant shall use and occupy the Demised Premises
pursuant to all of the other terms, covenants and conditions of this lease.

42.  AMENDING ARTICLE 11:
     --------------------

     Notwithstanding the provisions of Article 11, and in modification and
amplification thereof:

     A.   If Tenant shall desire to assign this Lease or to sublet all or a
portion of the Demised Premises, Tenant shall submit to Landlord a written
request for Landlord's consent to such assignment or subletting, which request
shall contain or be accompanied by the following information: (i) the name and
address of the proposed assignee or subtenant; (ii) a duplicate original or
photocopy of the proposed assignment agreement or sublease or a true and correct
photocopy of the offer from the proposed assignee or subtenant signed by such
proposed assignee or subtenant; (iii) the nature and character of the business
of the proposed assignee or subtenant and its proposed use of the Demised
Premises; and (iv) banking, financial and other credit information with respect
to the proposed assignee or subtenant reasonably sufficient to enable Landlord
to determine the financial responsibility of the proposed assignee or subtenant.

          Landlord shall then have the option to be exercised by written notice
given to Tenant within fifteen (15) days after receipt of Tenant's request for
consent to require a surrender of the Demised Premises if Tenant has requested
consent to an assignment of this lease or a subletting of all or substantially
all of the Demised Premises, or to require a surrender of a portion of the
Demised Premises which Tenant proposes to sublet, upon the terms and conditions
hereinafter provided.

     B.   If Landlord shall exercise its option to require a surrender of the
Demised Premises or portion thereof as provided above, then upon the proposed
commencement date of the subletting specified in Tenant's notice to Landlord,
the Demised Premises or portion intended to be sublet, as the case may be, shall
be surrendered to Landlord in accordance with the provisions of the Lease
pertinent to surrender, and this Lease shall cease and terminate insofar as the
Demised Premises or portion thereof, as the case may be, with the same force and
effect as though such proposed commencement date were the Expiration Date. If
only a portion of the Demised Promises is involved, the terms and conditions of
the Lease shall remain in full force and effect, except that the Fixed Rent and
additional rent shall be proportionately reduced based upon the number of square
feet of the portion of the Demised Premise surrendered. In addition, in the
event that less than all of the Demised Premises is surrendered:

          1.   Landlord shall cause to be constructed, at Landlord's sole cost
and expense, such alterations and connections as may be required in order to
physically separate such surrendered the portion of the Demised Premises from
the balance of the Demised Premises; and

          2.   After the proposed commencement date specified above, Landlord
shall, subject to Article 13 herein, have free access to enter to the Demised
Premises in order to complete the construction referred to in Subparagraph B1
above.

                                      -18-
<PAGE>

     C.   If Landlord does not exercise its option specified above, then
Landlord's consent to a subletting of all or a portion of the Demised Premises
or an assignment of Tenant's interest in this lease shall not be unreasonably
withheld or delayed on further condition that:

     1.   The proposed subtenant or assignee shall not be a school of any kind,
or an employment or placement agency or governmental or quasi governmental
agency, medical office or executive recruitment office;

     2.   The subletting or assignment shall be to a tenant whose occupancy will
be in keeping with the dignity and character of the then use and occupancy of
the Building and whose occupancy will not be more objectionable or more
hazardous than that of Tenant herein or impose any additional burden upon
Landlord in the operation of the Building;

     3.   No space shall be advertised or openly promoted to the general public
utilizing the name of the Landlord or any principal or partner thereof, or
stating or otherwise characterizing a rental rate;

     4.   The proposed sublessee or assignee shall not be an occupant of any
space in the Building or a party who dealt with Landlord or Landlord's agent
(directly or through a broker) with respect to space in the Building during the
six (6) months immediately preceding Tenant's request for Landlord's consent;

     5.   Tenant shall reimburse Landlord on demand for any reasonable costs
that may be incurred in connection with any assignment or sublease, including,
without limitation, the reasonable costs of making investigations as to the
acceptability of the proposed assignee or subtenant, and reasonable legal costs
incurred in connection with the granting of any requested consent, provided such
costs do not exceed $2,000.00 per each consent;

     6.   In case of a subletting, it shall be expressly subject to all of the
obligations of Tenant under this Lease and the further condition and restriction
that the subleased Demised Premises shall not be further sublet by the sublessee
in whole or in part, or any part thereof suffered or permitted by the sublessee
to be used or occupied by others, without the prior written consent of Landlord
in each instance;

     7.   Tenant, at Tenant's expense, shall provide and permit reasonably
appropriate means of ingress to and egress from the space sublet by Tenant; and

     8.   Tenant is not then in default under the terms, covenants and
conditions of this lease on Tenant's part to be observed and performed beyond
applicable notice and cure periods.

     D.   No permitted or consented to assignment or subletting shall be
effective or valid for any purpose whatsoever unless and until a counterpart of
the assignment or a counterpart or reproduced copy of the sublease shall have
been first delivered to the Landlord, and, in the event of an assignment, the
Tenant shall deliver to Landlord a written agreement executed and acknowledged
by the Tenant and such assignee wherein such assignee shall assume the due
performance of this Lease on Tenant's part to be performed for the balance of
the term of this Lease notwithstanding any other or further assignment.

     E.   Any transfer by operation of law or otherwise, of Tenant's interest in
this Lease or of a fifty (50%) percent or greater interest in Tenant (whether
stock, partnership interest or otherwise) shall be deemed an assignment of this
Lease for purposes of this Article except that the transfer of the outstanding
capital stock of any corporate tenant shall be deemed not to include any initial
public offering of Tenant's stock or the sale of such stock by persons or
parties through the "over-the-counter-market" or through any recognized stock
exchange, other than those deemed "insiders" within the meaning of the
Securities Exchange Act of 1934, as amended.

          Notwithstanding the provisions of this Article 42, the following
transfers shall not constitute an assignment for purposes hereof and shall be
permitted without Landlord's consent, even where effective control of Tenant may
shift as a result thereof: (i) the public offering or trading of Tenant's or
Tenant's parent's stock on a nationally recognized exchange or on the NASDAQ
over-the-counter or "small cap issues" markets, (ii) gifts, bequeaths,
inheritance or other devices between and among Tenant's shareholders (or
partners, as the case may be) and their families, or (iii) private placements
pursuant to which the proceeds are invested directly in Tenant or a related
entity of Tenant.

     F.   Landlord acknowledges and agrees that Tenant may enter into agreements
with Tenant's customers and users of voice, video, data, computer, telco, and
other communication equipment and systems ("Collocation Agreements") that
provide for the physical location of such equipment within the Demised Premises.
Such Collocation Agreements shall not be deemed a subletting or assignment under
this lease and Landlord shall not be entitled to any fee or additional rental
therefore. Landlord further acknowledges that Tenant shall be allowed to
interconnect such equipment to Tenant's equipment within the Demised Premises
and shall also be allowed to interconnect such equipment with telco services
provided by other third party local telephone providers at no additional charge
or cost.

                                      -19-
<PAGE>

     G.   Neither any assignment of Tenant's interest in this Lease nor any
subletting, occupancy or use of the Demised Premises or any part thereof by any
person other than Tenant, nor any collection of rent by Landlord from any person
other than Tenant as provided in Article 11 hereof, nor any application of any
such rent as provided in said Article 11 shall, in any circumstances, relieve
Tenant of its obligations fully to observe and perform the terms, covenants and
conditions of this Lease on Tenant's part to be observed and performed.

     H.   Notwithstanding anything to the contrary contained herein, if Landlord
shall consent to any assignment or subletting (other than in respect of an
assignment or subletting permitted under paragraph I below), then (i) in the
case of an assignment, if Tenant shall receive any consideration from its
assignee in connection with the assignment of this Lease, Tenant shall pay over
to Landlord, as additional rent, a sum equal to fifty (50%) percent of any such
consideration (including sums designated by the assignee as paid for the
purchase of Tenant's property in the Demised Premises, less the then net
unamortized or undepreciated cost of Tenant's property as determined on the
basis of the amortization schedule therefore utilized by Tenant in Tenant's
federal income tax returns, as shall exceed the brokerage commissions,
alterations expenses and attorneys' fees and disbursements (including, without
limitation, actual up-front, out-of-pocket payments for improvement allowances
or other concessions paid at or prior to the effective date of such assignment)
reasonably incurred by Tenant for such assignment or (ii) if Tenant shall sublet
the Demised Premises or any portion thereof to anyone for rents, additional
charges or other consideration which for any period shall exceed the rents
payable for the subleased space under this Lease for the same period, Tenant
shall pay Landlord, as additional rent, a sum equal to fifty (50%) percent of
any such excess less brokerage commissions, and attorneys' fees and
disbursements reasonably incurred by Tenant for such subletting (including,
without limitation, actual up-front, out-of-pocket payments for improvement
allowances or other concessions paid at or prior to the effective date of such
sublease) and all sums payable to Landlord pursuant to subdivision (ii) of this
Paragraph H shall be paid on the effective date of such assignment or on such
later date when, and to the extent, any such payments are made to Tenant by the
subtenant or assignee.

     I.   Tenant may, without Landlord's prior written consent, but upon prior
written notice to Landlord, assign or transfer its entire interest in this Lease
and the leasehold estate hereby created or sublet the whole or any portion of
the Demised premises to a related entity of Tenant (as hereinafter defined) or
an entity (1) to which substantially all of Tenant's assets are transferred or
(2) to which all of the capital stock of Tenant is transferred or into with or
with which Tenant is otherwise merged or consolidated; provided, however, that
(i) Tenant shall not be in default in any of the terms of this Lease beyond
applicable notice and cure periods, (ii) the proposed occupancy shall not
increase the office cleaning requirements (if any) or impose an unreasonable
extra burden upon the building equipment or building services and (iii) the
proposed subtenant or assignee shall not be entitled, directly or indirectly, to
diplomatic or sovereign immunity and shall be subject to the service of process
in, and the jurisdiction of the courts of, New York State. A "related entity",
as used in this Section shall mean with respect to an entity to which reference
is made, an entity which controls, is controlled by or is under common control
with such entity. For the purposes hereof, "control" shall be deemed to mean
ownership of not less than fifty (50%) percent of all of the voting stock of
such corporation or not less than fifty (50%) percent of all of the legal and
equitable interest in any other business entities or the ability to control the
business decision of such corporation or entity. Any such subletting shall not
be deemed to vest in any such related entity any right or interest in this Lease
or the Demised Premises nor shall it relieve, release, impair or discharge any
of Tenant's obligations hereunder.

     J.   Each sublease shall provide that it is subject and subordinate to this
Lease and to the matters to which this Lease is or shall be subordinate, and
that in the event of default by Tenant under this Lease, Landlord may, at its
option, take over all of the right, title and interest of Tenant, as sublessor,
under such sublease, and such sublessee shall, at Landlord's option, attorn to
Landlord pursuant to the then executory provisions of such sublease, except that
Landlord shall not (i) be liable for any previous act or omission of Tenant
under such sublease or, (ii) be subject to any offset not expressly provided in
such sublease which theretofore accrued to such sublease to which Landlord has
not specifically consented in writing or by any previous prepayment of more than
one month's rent.

46.  ELECTRIC CURRENT:
     -----------------

     A.   Definitions
          -----------

          For purposes of this Article 46, the following term shall have the
following meanings:

          The term "Landlord's Cost", shall mean, the then going cost per
kilowatt hour and kilowatt to Landlord of purchasing electricity, from the
Electricity Providers (herein defined) as adjusted from time to time for fuel
adjustment charges, rate adjustment charges, sales tax, and/or any other
factors.

          The term "Electricity Provider" shall mean any utility and any other
energy services company or companies, whether or not affiliated with Landlord,
that is supplying electric energy and capacity including but not limited to
generation, transmission, distribution and other ancillary services, to the
building and the Demised Premises, or directly to Tenant, regardless of whether
such Electricity Provider generates its own electricity at or near the building
or delivers such electricity over transmission and distribution equipment owned
by the Electricity Provider, the local utility or any other Electricity
Provider. Landlord may purchase such services from more than one Electricity
Provider.

B.   Method of Furnishing Electric Current to the Demised Premises
     -------------------------------------------------------------

          Tenant agrees that Landlord, that subject to Paragraph 5 hereof,
shall furnish electricity to Tenant on a "submetering" basis.

     1.   Submetering: Landlord shall, at Tenant's sole cost and expense
          pursuant to Article 52, install and maintain a meter or meters
          (collectively, the "Submeter") at a location designated by Landlord to
          measure Tenant's consumption of electricity in the Demised Premises
          only. If and so long as electric current is supplied by Landlord to
          the Demised Premises or other Tenant controlled areas to service
          Tenant's equipment and the air conditioning units and other
          appurtenant equipment contained therein or elsewhere in the Building,
          Tenant will pay Landlord or Landlord's designated agent, as additional
          rent for such service, the amounts applying to Tenant's measured
          electrical demand and consumption (as determined by such Submeter)
          Landlord's Cost, plus a fee (the "Overhead Charge") equal to nine (9%)
          percent of such charge to Landlord, representing
          administrative/overhead costs to Landlord. The amounts computed from
          the Submeter together with the Overhead Charge are herein collectively
          called the "Electricity Additional Rent". Landlord may from time to
          time, increase the Electricity Additional Rent based upon any
          increase in Landlord's Cost. Where more than one meter measures the
          electric service to Tenant (including such electric energy as is
          consumed in connection with the operation of the ventilation and air
          conditioning equipment servicing the Demised Premises), the electric
          service rendered through each meter may be computed and billed
          separately as above set forth. Bills for the Electricity Additional
          Rent (the "Bills") shall be rendered to Tenant at such time as
          Landlord may elect. In the event that such Bills are not paid within
          thirty (30) days after the same are rendered, Landlord may, after an
          additional thirty (30) days written notice and Tenant's failure to
          cure such default within such aggregate sixty (60) day period,
          discontinue the service of electric current to the Demised Premises
          without releasing Tenant from any liability under this Lease and
          without Landlord or Electrical Providers incurring any liability for
          any damage or loss sustained by Tenant as the result of such
          discontinuance. If any tax is imposed upon Landlord's receipts from
          the sale or resale of electric current to Tenant by any Federal, state
          or municipal authority, Tenant agrees that, unless prohibited by law,
          Tenant's Percentage of such taxes shall be passed on to, and included
          in the bill of, and paid by Tenant to Landlord as additional rent.

                                      -22-
<PAGE>

     2.   Subject to Article 46, Subparagraph B1, Tenant agrees not to connect
          any additional electrical equipment of any type to the building
          electric distribution system, without Landlord's prior written
          consent, which consent shall not be unreasonably withheld. Except as
          hereinafter provided, any additional risers, feeders, or other
          equipment proper or necessary to supply Tenant's electrical
          requirements, upon written request of Tenant, will be installed by
          Landlord, at the sole cost and expense of Tenant, if, in Landlord's
          reasonable judgment, the same are necessary and will not cause
          permanent damage or injury to the building or the Demised Premises, or
          cause or create a dangerous or hazardous condition or entail excessive
          or unreasonable alterations, repair or expense or interfere with or
          disturb other tenants or occupants.

     3.   Tenant's use of electric current in the Demised Premises shall not at
          any time exceed the capacity of any of the electrical conductors and
          equipment in or otherwise serving the Demised Premises, which is
          presently 208 three phase service (upgradable to a 480 three phase
          service by the installation of a 480 volt transformer, at Tenant's
          expense which shall be based on Landlord's actual cost for said
          installation of transformer without additional mark-up) with 20 watts
          per usable square foot available to the Demised Premises. At Tenant's
          expense, Landlord shall provide, at a rental rate of $15.00 per
          rentable square foot, space in the basement or sub-basement of the
          Building, for installation of Tenant's transformers. Subject to
          availability, Landlord and Tenant will determine the location of the
          480 volt transformer and any other equipment used in connection
          therewith. At Tenant's expense, Landlord shall provide additional
          amperage, up to a maximum full service of 4,000 amps, at an additional
          charge of $350.00 per additional amp for a total additional amperage
          cost of $ ___________(the "Additional Amperage Cost"). Within ten (10)
          business days from Lease execution, Landlord shall notify Tenant as to
          the location of the 4,000 amp service and that same shall be "live"
          (i.e., ready for Tenant's connections). The location of the 4,000 amp
          service shall be designated as "stab 6", which shall be exclusively
          designated for Tenant. Tenant shall pay Landlord the first $250,000.00
          of the Additional Amperage Cost in cash and any remaining balance
          thereof shall be paid by way of a reduction in Tenant's Free Rent (as
          provided in Article 41) ratably spread during months 13 through 48 of
          the Term of this Lease.

     4.   Subject to the provisions of paragraph 27 above, Landlord shall not be
          liable in any way to Tenant (other than for gross negligence or
          willful misconduct) for any failure or defect in the supply or
          character of electric energy furnished to the Demised Premises by
          reason of any requirement, act or omission of the utility serving the
          building with electricity or for any other reason.

     5.   Landlord reserves the right to discontinue furnishing electric energy
          to Tenant at any time upon sixty (60) days prior written notice to
          Tenant, provided that (i) Landlord discontinues the furnishing of
          electric energy to substantially all tenants in the Building and (ii)
          electric energy can be supplied by the Electricity Provider directly
          to Tenant, from and after the effective date of such termination,
          Landlord shall no longer be obligated to furnish Tenant with electric
          energy, provided, however, that such termination date may be extended
          for a time reasonably necessary for Tenant to make arrangements to
          obtain electric services directly from the Electrical Provider
          approved by Landlord. In the event Landlord discontinues furnishing
          electric energy to Tenant and Tenant must upgrade its equipment to
          obtain electric energy from another source, then Landlord shall pay
          Tenant's reasonable expenses in connection with such upgrade. If
          Landlord exercises such right of termination, this Lease shall remain
          unaffected thereby and shall continue in full force and effect; and
          thereafter Tenant shall diligently arrange to obtain electric service
          directly from the Electrical Provider approved by Landlord servicing
          the building, and may at Landlord's cost utilize the then existing
          electric feeders, risers and wiring serving the Demised Premises to
          the extent available and safely capable of being used for such purpose
          and only to the extent of Tenant's then authorized connected lead.
          Landlord shall not be obligated to pay any part of any cost required
          for Tenant's direct electric service, unless Landlord elects to
          terminate service of electricity as hereinbefore provided,

     6.   Notwithstanding any provisions of this Article 46, in no event shall
          (a) the fixed rent under this Lease be reduced by virtue of this
          Article 46 and (b) the cost to Tenant for electric energy be less than
          109% of Landlord's Cost.

     7.   Landlord will not unreasonably withhold or delay its consent to
          Tenant's request for additional electrical power and Landlord shall
          make a prompt and appropriate request to the Electricity Provider for
          such additional electrical power. Such additional electrical power
          shall be provided, subject to availability, at Tenant's expense at
          Landlord's then Building standard rates.

     It is specifically understood and agreed that this Lease may be offered to
Tenant for signature by the leasing or managing agent and is subject to
Landlord's acceptance and approval, and that Tenant shall have affixed its
signature hereto with the understanding that such act shall not, in any way,
bind Landlord or its agent until such time as this Lease shall have been
approved and executed by Landlord and delivered to Tenant.

49.  MISCELLANEOUS:
     --------------

     A.   Subject to Article 13 herein, without incurring any liability to
Tenant, Landlord may permit access to the Demised Premises and open the same,
whether or not Tenant shall be present, upon demand of any receiver, trustee,
assignee for the benefit of creditors, sheriff, marshall or court officer
entitled to, or reasonably purporting to be entitled to, such access for the
purpose of taking possession of, or removing, Tenant's property or for any other
lawful purpose (but this provision and any action by Landlord hereunder shall
not be deemed a recognition by Landlord that the person or official making such
demand has any right or interest in or to this Lease, or in or to the Demised
Premises), or upon demand of any representative of the fire, police, Building,
sanitation or other department of the city, state or federal governments.

     B.   No receipt of monies by Landlord from Tenant, after any reentry or
after the cancellation or termination of this Lease in any lawful manner, shall
reinstate the lease; and after the service of notice to terminate this Lease, or
after the commencement of any action, proceeding or other remedy, Landlord may
demand, receive and collect any monies due, and apply them on account of
Tenant's obligations under this Lease but without in any respect affecting such
notice, action, proceeding or remedy, except that if a money judgment is being
sought in any such action or proceeding, the amount of such judgment shall be
reduced by such payment.

     C.   If Tenant is in arrears in the payment of fixed rent or additional
rent, Tenant waives its right, if any, to designate the items in arrears against
which any payments made by Tenant are to be credited and Landlord may apply any
of such payments to any such items in arrears as Landlord, in its sole
discretion, shall determine, irrespective of any designation or request by
Tenant as to the items against which any such payments shall be credited.

     D.   No payment by Tenant nor receipt by Landlord of a lesser amount than
may be required to be paid hereunder shall be deemed to be other than on account
of any such payment, nor shall any endorsement or statement on any check or any
letter accompanying any check tendered as payment be deemed an accord and
satisfaction and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such payment due or pursue any other
remedy in this Lease provided.

     E.   If in this Lease it is provided that Landlord's consent or approval as
to any matter will not be unreasonably withheld, and it is established by a
court or body having final jurisdiction thereover that Landlord has been
unreasonable the only effect of such finding shall be that Landlord shall be
deemed to have given its consent or approval; but Landlord shall not be liable
to Tenant in any respect for money damages by reason of withholding its consent.

     F.   If payment of any Fixed Rent or Additional Rent shall not have been
paid by the tenth (10th) day after the date on which such amount was due and
payable, then, in addition to and without waiving or releasing any other
remedies of Landlord, a late charge of four cents ($.04) for each dollar overdue
shall be payable on demand by Tenant to Landlord as damages for Tenant's failure
to make prompt payment, in default of payment of any late charges, Landlord
shall have (in addition to all other remedies) the same rights as provided in
this Lease for nonpayment of Fixed Rent. Nothing in this Section contained and
no acceptance of late charges by Landlord shall be deemed to extend or change
the time for payment of Fixed Rent or Additional Rent.

     G.   If the Expiration Date or the date of sooner termination of this Lease
shall fall on a day which is not a business day, then Tenant's obligations
pursuant to Article 22 hereof shall be performed on or prior to the next
succeeding business day, Tenant expressly waives, for itself and for any person

                                      -24-

have under the provisions of Section 2201 of the New York Civil Practice Law and
Rules and of any similar or successor law of same import then in force, in
connection with any holdover proceedings which Landlord may institute to enforce
the provisions of this Lease. If the Demised Premises are not surrendered upon
the termination of this Lease, Tenant hereby indemnifies Landlord against
liability resulting from delay by Tenant in so surrendering the Demised
Premises, including any claims made by any succeeding tenant or prospective
tenant founded upon such delay. In the event Tenant remains in possession of the
Demised Premises after the termination of this Lease without the execution of a
new lease, Tenant, at the option of Landlord, shall be deemed to be occupying
the Demised Premises as a tenant from month to month, at a monthly rental equal
to 200% times the fixed rent and additional rent payable during the last month
of the term, subject to all of the other terms of this Lease insofar as the same
are applicable to a month-to-month tenancy. Tenant's obligations under this

     L.   To the extent that Tenant required use of any riser space i.e. the

or whether this Lease property conforms with requirements imposed by the

credited against the Tax Amount becoming due hereunder if such Tax Abatement
related to the Actual Benefit is thereafter revoked solely by reason of Tenant's

Tenant's business in the Demised Premises or its use and occupancy thereof, and
only to the extent Landlord shall have refunded any

limiting, as a result of the exercise by Tenant of a right to terminate this
Lease, or assignment of this Lease, or subleasing of the Premises, or for
Tenant's failure to meet and continue to meet any of the eligibility
requirements under the Program, or Tenant's breach under this Lease), together
with any interest at the highest rate allowed by law commencing upon the date
such payment is to be made, along with all penalties which may be imposed

          Lease; and

          2.   Tenant is not in default (after the expiration of applicable
          notice and grace periods, if any) under this Lease as of the time of
          the giving of the Extension Notice and the Commencement Date of the
          First Extension Term.

     B.   The Fixed Rent payable by Tenant to Landlord during the First
Extension Term shall be a sum equal to the fair market rent for the Demised
Premises as determined as of the date occurring three (3) months prior to the
Commencement Date of the First Extension Term (such date is hereinafter called
the "Determination Date") and which determination shall be made within a
reasonable period of time after the occurrence of the Determination Date
pursuant to the provisions of Paragraph C hereof, but such Fixed Rent shall in
no event be less than the aggregate Fixed Rent in effect under the Lease for
the entire Demised Premises for the last month of the Term hereof (without
giving effect to any temporary abatement of Fixed Rent under the provisions of
this Lease).

     C.   1.   Landlord and Tenant shall endeavor to agree as to the amount of
the fair market rent for the Demised Premises pursuant to the provisions of
Paragraph B hereof, during the fifteen (15) day period following the
Determination Date. In the event that Landlord and Tenant can not agree as to
the amount of the fair market rent within such fifteen (15) day period following
the Determination Date, then Landlord or Tenant may initiate the appraisal
process provided for herein by giving notice to that effect to the other, and
the party so initiating the appraisal process (such party hereinafter called the
"Initiating Party") shall specify in such notice the name and address of the
person designated to act as an arbitrator on its behalf. Within fifteen (15)
days after the designation of such arbitrator, the other party (hereinafter
called the "Other Party") shall give notice to the Initiating Party specifying
the name and address of the person designated to act as an arbitrator on its
behalf. If the Other Party fails to notify the Initiating Party of the
appointment of its arbitrator within the time above specified, then the
Initiating Party may apply to the American Arbitration Association or any
organization which is a successor thereto (the "AAA") for appointment of the
Other Party's arbitrator, which appointment shall be made by the AAA with ten
(10) days after such application. The two arbitrators so chosen shall meet
within ten (10) days after the second arbitrator is appointed and if, within
fifteen (15) days after the second arbitrator is appointed, the two arbitrators
shall not agree, they shall together appoint, by written instrument delivered to
both Landlord and Tenant, a third arbitrator (the "Arbitrator"), which
instrument shall be so delivered with such Arbitrator's retention agreement
which shall provide, inter alia, that (x) each of Landlord and Tenant agree to
                     ----- ----
pay fifty (50%) percent of all the Arbitrator's fees and expenses (including,
without limitation, witness fees and other similar expenses) at its standard
rates, and (y) the Arbitrator shall deliver to Landlord and Tenant its written
announcement as to its selection of either Tenant's determination of fair market
value rent or Landlord's determination of fair market value rent. In the event
of their being unable to agree upon such appointment within thirty (30) days
after the appointment of the second arbitrator, then either Landlord or Tenant
may apply for the appointment of the Arbitrator (with a copy of such application
delivered to the other party by certified mail) to the AAA. Within five (5) days
of receipt of such retention

                                      -29-
<PAGE>

agreement and such instrument, each of Landlord and Tenant shall execute such
agreements and return it by overnight mail to the Arbitrator with a check for
50% of the Arbitrator's fees and simultaneously deliver to the other party a
copy of such signed agreement and check. If either party shall fail to do so,
then in the case of Tenant, Landlord's determination of fair market value rent
shall prevail; and in the case of Landlord, Tenant's determination of fair
market value rent shall prevail.

          2.   Each party shall pay the fees and expenses of their respective
original arbitrators appointed by or for such party, and half the fees and
expenses of the third arbitrator and all other expenses (not including the
attorneys fees, witness fees and similar expenses of the parties which shall be
borne separately by each of the parties) of the arbitration shall be borne by
the parties equally.

          3.   The Arbitrator shall determine the fair market rent of the
Demised Premises and render a written certified report of its determination to
both Landlord and Tenant within thirty (30) days of the appointment of the first
two arbitrators or fifteen (15) days from the appointment of the third
arbitrator if such Arbitrator is appointed pursuant to this Paragraph; and the
fair market rent, so determined, shall be applied to determine the Fixed Rent
pursuant to Paragraph B hereof.

          4.   Each of the arbitrators selected as herein provided shall be a
qualified member of the American Institute of Real Estate Appraisers (or any
successor of such institute, or if such organization or successor shall no
longer be in existence, a recognized national association or institute of
appraisers), possess a valid and current MAI designation, and have at least ten
(10) years experience in the leasing and renting of office space in first class
office buildings in New York City, New York.

          5.   If Landlord notifies Tenant that the Fixed Rent for the First
Extension Term shall be equal to the aggregate Fixed Rent in effect under this
Lease for the last month of the Term (without giving effect to any temporary
abatement thereof), then the provisions of Subsections 1, 2, 3 and 4 of this
Paragraph C shall be inapplicable and have no force or effect.

          6.   In the event Landlord or Tenant initiates the appraisal process
and as of the Commencement Date of the First Extension Term the amount of the
fair market rent has not been determined, Tenant shall continue to pay the Fixed
Rent in effect under this Lease for the last month of the Term and when such
determination has been made, an appropriate retroactive adjustment shall be made
as of the Commencement Date of the First Extension Term.

     D.   Except as provided in Paragraphs A and B hereof, Tenant's occupancy of
the Demised Premises during the First Extension Term shall be on the same terms
and conditions as are in effect immediately prior to the expiration of the Term
of this Lease, provided, however, Tenant shall have no further right to extend
the term of this Lease pursuant to this Article 55.

     E.   If Tenant does not send the Extension Notice pursuant to the
provisions of Paragraph A hereof, this Article 55 shall have no force or effect
and shall be deemed deleted from this Lease.

     F.   If this Lease is renewed for the First Extension Term, then Landlord
or Tenant can request the other party hereto to execute an instrument setting
forth the exercise of Tenant's right to extend the term of this Lease and the
last day of the First Extension Term.

     G.   If Tenant exercises its right to extend the term of the Lease for the
First Extension Term pursuant to this Article 55, the phrases "the term of this
Lease" or "the term hereof" as used in the Lease, shall be construed to include,
when practicable, the First Extension Term.
