Lease Forms

  • Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

                                      LEASE

         THIS LEASE (the "Lease") is made and entered into as of the 6th day of
July 1999, by and between HV 645 Harrison, Inc., a California corporation (the
"Landlord"), and Linkshare Corporation, a Delaware corporation (the "Tenant").

1.       Premises

         (a) Subject to and upon the terms, covenants and conditions hereinafter
set forth, Landlord leases to Tenant and Tenant rents from Landlord those
certain premises as set forth in the Basic Lease Information attached hereto and
as approximately shown on the plan attached hereto as Exhibit A (the "Premises")
on the ground floor of the building located at 645 Harrison Street, San
Francisco, California (the "Building").

         (b) Tenant shall accept the Premises and the Building in their "as-is"
condition; provided, however, Landlord shall deliver the Premises in a broom
clean condition with the lighting, electrical and plumbing in good operating
condition. In addition Landlord shall repaint and recarpet the Premises with
paint and carpet mutually agreeable; provided the cost shall not exceed $17,400.
All alterations shall be performed in accordance with the terms of Section 9
below. Landlord acknowledges that Tenant is planning on demolishing non-load
bearing walls in the Premises as part of its initial construction of
improvements; and that Landlord shall not require the restoration of such walls
at the end of the term of this Lease.

2.       Term

         This Lease shall be for the term commencing on the Commencement Date
(provided Tenant shall have the right of access to the Premises upon the full
execution of this Lease, which access shall be governed by the terms of this
Lease, except the obligation to pay Base Rental) and expiring on the date that
is 48 and 1/2 months following the Commencement Date, unless sooner terminated
as provided herein (the "Term"). If Landlord, for any reason whatsoever, cannot
deliver possession of the Premises to Tenant on the date specified herein as the
Commencement Date, this Lease shall not be void or voidable, nor shall Landlord
be liable to Tenant for any loss or damage resulting therefrom. In that event,
however, Tenant shall not be liable for any Base Rental or Additional Charges
(as hereinafter defined) until Landlord delivers possession of the Premises to
Tenant.

3.       Rent

         (a) Tenant shall pay to Landlord "Base Rental" throughout the Term in
monthly installments as set forth in the Basic Lease Information attached
hereto, due and payable upon the first day of each and every month during the
Term, without any further notice from, or demand by Landlord and without any
offset or deduction whatsoever, in lawful money of the United States of America,
at the address set forth in the Basic Lease Information attached hereto or
elsewhere as designated from time to time by Landlord's written notice to
Tenant. Tenant shall also pay to
<PAGE>

Landlord all charges and other amounts whatsoever as provided in this Lease
("Additional Charges"); and such Additional Charges shall be payable to Landlord
at the place where the Base Rental is payable and Landlord shall have the same
remedies for a default in the payment of Additional Charges as for a default in
the payment of Base Rental. If the Commencement Date should occur on a day other
than the first day of a calendar month, or the Expiration Date should occur on a
day other than the last day of a calendar month, then the Base Rental and
Additional Charges for such fractional month shall be prorated on a daily basis.

         (b) Tenant recognizes that late payment of any Base Rental or
Additional Charges will result in additional administrative expense to Landlord
and will impair Landlord's ability to meet its obligations with respect to the
Building and otherwise, the exact extent of which additional expense and
impairment will be extremely difficult or impractical to determine. Tenant
therefore agrees that if any Base Rental or Additional Charges remain unpaid for
a period of five (5) days after the date the same is due, the amount of such
unpaid Base Rental or Additional Charges shall be increased by a late charge to
be paid to Landlord by Tenant in an amount equal to ten percent (10%) of the
amount of the past due Base Rental and/or Additional Charges. The amount of the
late charge to be paid to Landlord by Tenant on any delinquent Base Rental
and/or Additional Charges shall be reassessed and added to Tenant's obligation
for each successive monthly period accruing after the date on which the late
charge is initially imposed until such late charge and all delinquent Base
Rental and Additional Charges have been paid in full by Tenant. Tenant agrees
that such amount is a reasonable estimate of the loss and expense to be suffered
by Landlord as a result of any such late payment by Tenant. The provisions of
this Paragraph 3(b) in no way relieve Tenant of the obligation to pay Base
Rental or Additional Charges on or before the date on which they are due, nor do
the terms of this Paragraph 3(b) in any way affect Landlord's remedies pursuant
to Paragraph 18 in the event any Base Rental or Additional Charges are unpaid
after the date due.

4.       Additional Charges.  For purposes of this Paragraph 4, the following
terms shall have the meanings hereinafter set forth:

                  (i) "Base Year" shall mean the calendar year 2000.

                  (ii) "Taxes" shall mean all impositions, taxes, assessments
         (special or otherwise), and other governmental liens or charges of any
         kind or nature whatsoever, ordinary and extraordinary, foreseen and
         unforeseen, and any substitute therefor, including all taxes
         attributable in any manner to the Premises, the land on which the
         Premises is located or the rents (however the term may be defined)
         receivable therefrom or any charge or other payment required to be paid
         to any governmental authority, whether or not any of the foregoing
         shall be designated "real estate tax", "sales tax", "rental tax",
         "excise tax", "business tax", or designated in any other manner (except
         only those taxes of the following categories: any inheritance, estate
         succession, transfer or gift taxes imposed upon Landlord or any income
         taxes specifically payable by Landlord as a separate tax paying entity
         without regard to Landlord's income source as arising from or out of
         the Premises and/or the land on which it is located). Taxes shall also
         include reasonable legal fees, costs, and disbursements incurred in
         connection with proceedings to contest, determine, or reduce such
         Taxes.


                                        2
<PAGE>

                  (iii) "Operating Costs" shall mean all costs incurred by
         Landlord in connection with owning, operating and maintaining the
         Building. Operating Costs shall not include capital costs incurred by
         Landlord that are not required to be made to the Building by law or for
         the health and safety of the occupants of the Building.

                  (iv) "Tenant's Share" shall mean 4.3%.

         (a) Commencing upon January 1, 2001, tenant shall pay to Landlord as
Additional Charges, each month, an amount equal to Tenant's Share of any
increase in Taxes and Operating Costs from the Base Year.

         (b) Tenant shall pay, prior to delinquency, all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Tenant contained in the Premises or elsewhere. When possible, Tenant
shall cause said trade fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of
Landlord. If any of Tenant's said personal property shall be assessed with
Landlord's real property, Tenant shall pay Landlord the taxes attributable to
Tenant within 10 days after receipt of a written statement setting forth the
taxes applicable to Tenant's property.

5.       Security Deposit and Letter of Credit

         Tenant concurrently with the execution of this Lease, has deposited
with Landlord the sum set forth in the Basic Lease Information attached hereto,
the receipt of which is hereby acknowledged by Landlord as security for the
faithful performance by Tenant of all terms, covenants and conditions of this
Lease. Tenant agrees that Landlord may apply the security deposit, after the
lapse of any applicable cure period, to remedy any failure by Tenant to repair
or maintain the Premises or to perform any other terms, covenants and conditions
contained herein or make any payment owing hereunder. If Tenant has kept and
performed all terms, covenants and conditions of this Lease during the Term,
Landlord will, within thirty (30) days after the expiration hereof, promptly
return the security deposit to Tenant or the last permitted assignee of Tenant's
interest hereunder. Should Landlord use any portion of the security deposit to
cure any default by Tenant hereunder, Tenant shall forthwith replenish the
security deposit to the original amount. Landlord shall not be required to keep
the security deposit separate from its general funds, and Tenant shall not be
entitled to interest on any such deposit. Upon the occurrence of any Events of
Default (as defined in Paragraph 18 of this Lease) the security deposit shall
become due and payable to Landlord to the extent required to compensate Landlord
for damages incurred, or to reimburse Landlord as provided herein, in connection
with any such Event of Default.

6.       Use and Compliance with Laws

         (a) Tenant shall use and occupy the Premises for general office and for
no other use or purpose.


                                        3
<PAGE>

         (b) Tenant shall not use the Premises or permit anything to be done in
or about the Premises that will in any way conflict with any law, statute,
ordinance or governmental rule or regulation now in force or which may hereafter
be enacted or promulgated. Tenant shall not do or permit anything to be done in
or about the Premises or bring or keep anything therein which will in any way
increase the rate of any insurance upon the Building or any of its contents or
cause a cancellation of such insurance or otherwise affect such insurance in any
manner, and Tenant shall at its sole cost and expense promptly comply with all
laws, statutes, ordinances and governmental rules, regulations or requirements
now in force or which may hereafter be in force and with the requirements of any
board of fire underwriters or other similar body now or hereafter constituted
relating to or affecting the condition, use or occupancy of the Premises,
excluding structural changes not related to or affected by alterations or
improvements made by Tenant or Tenant's use of the Premises.

7.       Hazardous Substances

         Except for Hazardous Substances on or in the Premises as of the
Commencement Date, Tenant will not cause, suffer or permit any Hazardous
Substance (as hereinafter defined) to be brought, kept or stored within the
Premises, and Tenant will not engage in or permit any other person to engage in
any activity, operation or business upon the Premises that involves the
generation, manufacture, refining, transportation, treatment, storage, handling
or disposal of any Hazardous Substance that would or could result in Tenant,
Landlord, the Premises, or the Building to be subject to any law, statute,
ordinance, or regulation or rule of common law pertaining to health, industrial
hygiene, or the environment. Tenant shall be responsible for any violation of
this Article 7 by any subtenant or other occupant of the Premises. The term
"Hazardous Substance" shall include, without limitation those substances,
materials and wastes that are or become regulated under applicable local, state
or federal law, or the United States government, or which are classified as
hazardous or toxic under federal, state, or local laws or regulations.

8.       Utilities and Janitorial

         Tenant shall pay for all water, gas, heat, light, power, telephone and
other utilities and services supplied to the Premises, together with any taxes
thereon. If any such services are not separately metered to Tenant, Tenant shall
pay a reasonable proportion to be determined by Landlord of all charges jointly
metered with other premises based upon estimated usage of each tenant. Tenant,
at Tenant's sole cost, shall be responsible for providing janitorial services to
the Premises.

9.       Alterations

         Tenant shall not make any alternations, additions or improvements
(collectively, "Alterations") in or to the Premises without the prior written
consent of Landlord, which shall not be unreasonably withheld, but may be
predicated upon but not limited to Tenant's use of contractors who are
reasonably acceptable to Landlord; and any Alterations, except for Tenant's
movable furniture and equipment, at Landlord's election, shall immediately
become Landlord's property and,


                                        4
<PAGE>

at the end of the Term, shall remain on the Premises without compensation to
Tenant or, if Landlord shall elect, be removed by Tenant prior to the expiration
date of this Lease. All Alterations shall be completed in compliance with all
laws, codes, rules, and ordinances in effect at the time of such Alterations. In
the event the making of any Alterations triggers any additional work to be
performed to the Premises or the Building, such additional work shall be
performed at Tenant's sole cost and expense. In the event Tenant fails to remove
any Alterations required by Landlord to be removed, Landlord may remove such
Alterations and Tenant shall be obligated to immediately reimburse Landlord for
the cost therefor. In the event Landlord consents to the making of any
Alterations by Tenant, the same shall be made by Tenant, at Tenant's sole cost
and expense, in accordance with plans and specifications approved by Landlord,
and any contractor or person selected by Tenant to make the same must first be
approved in writing by Landlord, such approval not to be unreasonably withheld
or delayed. Upon the expiration or sooner termination of the Term, Tenant shall
upon written demand by Landlord (to be provided at the time such approval for
Alterations is requested) and at Tenant's sole cost and expense, promptly remove
any Alterations made by or for the account of Tenant that are designated by
Landlord to be removed, and Tenant shall at its sole cost and expense, promptly
repair and restore the Premises to its original condition.

10.      Repair

         (a) Tenant shall take good care of the Premises and, at Tenant's cost
and expense, shall make all repairs and replacements to preserve the Premises in
good working order and condition normal wear and tear and damage due to casualty
excepting, except that Tenant shall not be required to make any such structural
repairs or structural replacements unless necessitated or occasioned by the
acts, omissions or negligence of Tenant, or any of its employees, contractors,
agents or invitees, or by the manner of Tenant's use or occupancy of the
Premises. Landlord shall not be liable for and there shall be no abatement of
Base Rental or Additional Charges with respect to any injury to or interference
with Tenant's business arising from any repairs, maintenance, alteration or
improvement in or to any portion of the Building, including the Premises, or in
or to the fixtures, appurtenances and equipment therein. Landlord shall use its
reasonable effort to perform any repairs, maintenance, alterations or
improvements of things and in a manner so as to minimize any disturbance to
Tenant. Tenant hereby waives and releases its right to make repairs at
Landlord's expense under Sections 1941 and 1942 of the California Civil Code or
under any similar law, statute or ordinance now or hereafter in effect. In
addition, Tenant hereby waives and releases its right to terminate this Lease
under Section 1932(1) of the California Civil Code or under any similar law,
statute or ordinance now or hereafter in effect.

         (b) All repairs and replacements made by or on behalf of Tenant or any
person claiming through or under Tenant shall be made and performed (i) at
Tenant's sole cost and expense and at such time and in such manner as Landlord
may reasonably designate, (ii) by contractors or mechanics reasonably approved
by Landlord, (iii) so that same shall be at least equal in quality, value, and
utility to the original work or installation, (iv) in accordance with the
reasonable rules and regulations for the Building adopted by Landlord from time
to time, and (v) in accordance with all applicable laws and regulations of
governmental authorities having jurisdiction over the Premises.


                                        5
<PAGE>

11.      Liens

         Tenant shall keep the Premises free from any liens arising out of any
work performed, material furnished or obligations incurred by Tenant. In the
event that Tenant shall not, within ten (10) days following the imposition of
any such lien, cause the same to be released of record by payment or posting of
a proper bond, Landlord shall have, in addition to all other remedies provided
herein and by law, the right, but not the obligation, to cause the same to be
released by such means as it shall deem proper, including payment of the claim
giving rise to such lien. All such sums paid by Landlord and all expenses
incurred by it in connection therewith shall be considered Additional Charges
and shall be payable to it by Tenant on demand with interest at the maximum rate
permitted by law. Landlord shall have the right at all times to post and keep
posted on the Premises any notices permitted or required by law, or which
Landlord shall deem proper, for the protection of Landlord, the Premises and the
Building from mechanics' and materialmen's liens, and Tenant shall give to
Landlord at least five (5) business days' prior notice of commencement of any
construction in the Premises.

12.      Assignment and Subletting

         (a) Tenant shall not directly or indirectly, voluntarily or by
operation of law, sell, assign, encumber, pledge or otherwise transfer or
hypothecate all or any part of the Premises or Tenant's leasehold estate
hereunder (collectively, "Assignment"), or permit the Premises to be occupied by
anyone other than Tenant or sublet the Premises or any portion thereof
(collectively, "Sublease") without Landlord's prior written consent in each
instance, which consent may not be unreasonably withheld by Landlord.

         (b) Without limiting the other instances in which it may be reasonable
for Landlord to withhold its consent to an Assignment or Sublease, Landlord and
Tenant acknowledge that it shall be reasonable for Landlord to withhold its
consent in, the following instances:

                  (i) if at the time consent is requested or at any time prior
         to the granting of consent, Tenant is in default under this Lease or
         would be in default under this Lease but for the pendency of any grace
         or cure period under Paragraph 18 below;

                  (ii) if the proposed assignee or sublessee is a governmental
         agency;

                  (iii) if, in Landlord's judgment, the use of the Premises by
         the proposed assignee or sublessee would not be compatible to the types
         of use by other tenants in the Building, would entail any alterations
         which would lessen the value of the leasehold improvements in the
         Premises, would result in more than a reasonable number of occupants
         per floor, would require unreasonable increased services by Landlord or
         would conflict with any so-called "exclusive" or percentage lease then
         in favor of another tenant of the Building;


                                        6
<PAGE>

                  (iv) if, in Landlord's reasonable judgment, the financial
         strength of the proposed assignee or sublessee does not meet the credit
         standards applied by Landlord for other tenants under leases with
         comparable terms, or the character, reputation, or business of the
         proposed assignee or sublessee is not consistent with the quality of
         the other tenancies in the Building;

                  (v) if the Sublease would result in the division of the
         Premises into three or more units; or

                  (vi) if the proposed assignee or sublessee is an existing
         tenant of the Building or Landlord is currently marketing space in the
         Building to such proposed assignee or sublessee.

         (c) If Tenant desires at any time to enter into an Assignment or
Sublease, it shall first give written notice ("Tenant's Notice") to Landlord of
its desire to do so, which notice shall contain (i) the name of the proposed
assignee or subtenant, (ii) the terms and provisions of the proposed Assignment
or Sublease, and (iii) such financial information as Landlord may reasonably
request concerning the proposed assignee or subtenant.

         (d) If Landlord consents by delivery a written notice to Tenant, to an
Assignment or a Sublease within fifteen (15) days of receipt of Tenant's Notice,
Tenant may thereafter, within ninety (90) days after Landlord's consent, but not
later than the expiration of said ninety (90) days, enter into such Assignment
or Sublease, upon the terms and conditions set forth in the notice furnished by
Tenant to Landlord pursuant to Paragraph 12(c).

         (e) In the case of an Assignment, fifty percent (50%) of any sums or
other, economic consideration received by Tenant as a result of such Assignment
shall be paid to Landlord, after deducting the cost to Tenant of any
improvements made for such Assignment and the cost to Tenant of any broker fees
in connection with such Assignment. In the case of a Sublease, fifty percent
(50%) of any sums or economic consideration received by Tenant as a result of
such Sublease shall be paid to Landlord after first deducting the rental due
hereunder and after deducting the cost to Tenant of any improvements made for
such Assignment and the cost to Tenant of any broker fees in connection with
such Assignment, prorated to reflect only rental allocable to the sublet portion
of the Premises.

         (f) Notwithstanding any of the above provisions of this Section to the
contrary, if Tenant notifies Landlord that it desires to enter into a Transfer,
Landlord, in lieu of consenting to such Assignment or Sublease, may elect (x) in
the case of an assignment or a sublease of the entire Premises, to terminate
this Lease, or (y) in the case of a sublease of less than the entire Premises,
to terminate this Lease as it relates to the space proposed to be subleased by
Tenant. In such event, this Lease will terminate (or the space proposed to be
subleased will be removed from the Premises subject to this Lease and the Base
Rent and Tenant's Share under this Lease shall be proportionately reduced) on
the date the Transfer was proposed to be effective, and Landlord may lease such
space to any party, including the prospective Transferee identified by Tenant.


                                        7
<PAGE>

         (g) No consent by Landlord to any Assignment or Sublease by Tenant
shall relieve Tenant of any obligation to be performed by Tenant under this
Lease, whether arising before or after the Assignment or Sublease. The consent
by Landlord to any Assignment or Sublease shall not relieve Tenant from the
obligation to obtain Landlord's express written consent to any other Assignment
or Sublease. Any Assignment or Sublease that is not in compliance with this
Paragraph 12 shall be void and, at the option of Landlord, shall constitute a
material default by Tenant under this Lease. The acceptance of Base Rental or
Additional Charges by Landlord from a proposed assignee or sublessee shall not
constitute the consent to such Assignment or Sublease by Landlord.

         (h) Any sale or other transfer, including by consolidation, merger or
reorganization of a majority of the voting stock of Tenant, if Tenant is a
corporation, shall not be an Assignment for purposes of this Paragraph 12.

         (i) Each assignee of this Lease shall assume all obligations of Tenant
under this Lease and shall be and remain liable jointly and severally with
Tenant for the payment of Base Rental and Additional Charges, and for the
performance of all the terms, covenants and conditions herein contained on
Tenant's part to be performed. No Assignment shall be binding on Landlord unless
the assignee or Tenant shall deliver to Landlord a counterpart of the Assignment
and an instrument in recordable form that contains a covenant of assumption by
the assignee satisfactory in substance and form to Landlord, but the failure or
refusal of the assignee to execute such instrument of assumption shall not
release or discharge the assignee from its liability as set forth above.

13.      Insurance and Indemnification

         (a) Except to the extent caused by the gross negligence of Landlord,
Tenant agrees to defend, protect and indemnify Landlord against and save
Landlord harmless from any and all loss, cost, liability, damage and expense,
including without limitation, penalties, fines and reasonable counsel fees and
disbursements, incurred in connection with or arising from any cause whatsoever
in, on or about the Premises, including without limiting the generality of the
foregoing: (i) any default by Tenant in the observance or performance of any of
the terms, covenants or conditions of this Lease on Tenant's part to be observed
or performed, or (ii) the use or occupancy or manner of use or occupancy of the
Premises by Tenant or any person or entity claiming through or under Tenant, or
(iii) the condition of the Premises or any occurrence or happening on the
Premises from any cause whatsoever, or (iv) any sots, omissions or negligence of
Tenant or any person or entity claiming through or under Tenant, or of the
contractors, agents, servants, employees, visitors or licensees of Tenant or any
such person or entity, in, on or about the Premises or the Building, either
prior to the commencement of, during, or after the expiration of the Term,
including without limitation any acts, omissions or negligence in making or
performing any Alterations. In the event any action or proceeding is brought
against Landlord for any claim against which Tenant is obligated to indemnify
Landlord hereunder, Tenant upon notice from Landlord shall defend such action or
proceeding at Tenant's sole expense by counsel selected by Landlord. The
provisions of this


                                        8
<PAGE>

Paragraph 13 shall survive the expiration or termination of this Lease with
respect to any claims or liability occurring prior to such expiration or
termination.

         (b) Tenant shall procure at its cost and expense and keep in effect
during the Term commercial general liability insurance including contractual
liability with a minimum combined single limit of liability of Two Million
Dollars ($2,000,000.00) or such greater amount as Landlord may reasonably
specify from time to time by written notice to Tenant. Such insurance shall name
Landlord and the current property manager of the Building as additional insured,
shall specifically include the liability assumed hereunder by Tenant (provided
that the amount of such insurance shall not be construed to limit the liability
of Tenant hereunder), and shall provide that it is primary insurance, and not
excess over or contributory with any other valid, existing and applicable
insurance in force for or on behalf of Landlord, and shall provide that Landlord
shall receive thirty (30) days' written notice from the insurer prior to any
cancellation or change of coverage. Tenant shall deliver policies of such
insurance or certificates thereof to Landlord on or before the Commencement
Date, and thereafter at least thirty (30) days before the expiration dates of
expiring policies; and, in the event Tenant shall fail to procure such
insurance, or to deliver such policies or certificates, Landlord may, at its
option, procure the same for the account of Tenant, and the cost thereof shall
be paid to Landlord as Additional Charges within five (5) days after delivery to
Tenant of bills therefor. Tenant's compliance with the provisions of this
Paragraph 13(b) shall in no way limit Tenant's liability under any of the other
provisions of this Paragraph 13.

         (c) Landlord shall procure and keep in effect during the Term casualty
insurance insuring the Building, excluding any improvements or Alterations made
by Tenant, and Tenant shall pay Tenant's Share of the annual cost within thirty
days after receipt of an invoice from Landlord.

14.      Waiver of Subrogation

         Landlord and Tenant shall each obtain from their respective insurers
under all policies of fire, theft, public liability, workers' compensation and
other insurance maintained by either of them at any time during the Term
insuring or covering the Building or any portion thereof or operations therein,
a waiver of all rights of subrogation which the insurer of one party might
otherwise have against the other party, and Landlord and Tenant shall each
indemnify the other against any loss or expense, including reasonable attorneys'
fees, resulting from the failure to obtain such waiver.

15.      Damage and Destruction

         If the Premises or the Building are damaged by fire or other casualty,
Landlord shall forthwith repair the same, provided that such repairs can be made
within ninety (90) days after the date of such damage under the laws and
regulations of the federal, state and local governmental authorities having
jurisdiction thereof. In such event, this Lease shall remain in full force end
effect except that Tenant shall be entitled to a proportionate reduction of Base
Rental based upon the extent to which such damage and the making of such repairs
by Landlord shall interfere with the business carried on by Tenant in the
Premises. Within twenty (20) days after the date of such damage,


                                        9
<PAGE>

Landlord shall notify Tenant whether or not such repairs can be made within
ninety (90) days after the date of such damage. If such repairs cannot be made
within ninety (90) days from the date of such damage, Landlord and Tenant shall
each have the option within thirty (30) days after the date of such damage to
terminate this Lease as of a date specified in such notice, which date shall be
not less than thirty (30) nor more than sixty (60) days after notice is given.
In case of termination, the Base Rental shall be reduced by a proportionate
amount based upon the extent to which such damage interfered with the business
carried on by Tenant in the Premises, and Tenant shall pay such reduced Base
Rental up to the date of termination. The repairs to be made hereunder by
Landlord shall not include, and Landlord shall not be required to repair, any
damage to the property of Tenant. Tenant hereby waives the provisions of Section
1932, subdivision 2, and Section 1933, subdivision 4, of the Civil Code of
California.

16.      Eminent Domain

         If any part of the Premises shall be taken or appropriated under the
power of eminent domain such that the balance of the Premises is rendered
unsuitable for its intended use, either party shall have the right to terminate
this Lease at its option. If any part of the Building shall be taken or
appropriated under power of eminent domain, Landlord may terminate this Lease at
its option upon at least thirty (30) days notice to Tenant. In either of such
events, Landlord shall receive (and Tenant shall assign to Landlord upon demand
from Landlord) any income, rent, award or any interest therein which may be paid
in connection with the exercise of such power of eminent domain provided,
however, that Tenant may receive the portion of the sum paid by virtue of such
proceedings to Tenant in its own right for relocation expenses and damage to
Tenant's personal property. If a part of the Premises shall be so taken or
appropriated and such taking or appropriation does not render the balances of
the Premises unsuitable for its intended use or neither party hereto elects to
terminate this Lease, and if the Premises have been damaged as a consequence of
such partial taking or appropriation, Landlord shall restore the Premises
continuing under this Lease at Landlord's cost and expense. Thereafter, the Base
Rental to be paid under this Lease for the remainder of the term shall be
proportionately reduced, such reduction to be based upon the extent to which the
partial taking or appropriation shall interfere with the business carried on by
Tenant in the Premises. Notwithstanding anything to the contrary contained in
this Paragraph 16, in the case of any temporary taking of any part of the
Premises during the Term, this Lease shall be and remain unaffected by such
temporary taking and Tenant shall continue to pay in full the Base Rental
payable hereunder, and Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and Landlord shall be entitled to receive that portion of any
award which represents the cost of restoration of the Premises and the use and
occupancy of the Premises after the end of the Term.

17.      Right of Entry

         Landlord, or any of its agents, shall have the right to enter the
Premises during all reasonable hours to examine the same or to make such
repairs, additions or alterations as may be deemed


                                       10
<PAGE>

necessary for the safety, comfort, or preservation thereof, or of the Building,
or to exhibit the Premises at any time within one hundred eight (180) days
before the expiration of this Lease.

18.      Events of Default and Remedies

         (a) The occurrence of any one or more of the following events ("Event
of Default") shall constitute a breach of this Lease by Tenant:

                  (i) Tenant fails to pay any Base Rental under this Lease as
         and when such rent becomes due and payable and such failure continues
         for more than five (5) days after Landlord gives written notice thereof
         to Tenant; provided, however, that after the second such failure in a
         calendar year, only the passage of time, but no further notice, shall
         be required to establish an Event of Default in the same calendar year;
         or

                  (ii) Tenant fails to pay any Additional Charges or other
         amount of money or charge payable by Tenant hereunder as and when such
         Additional Charges or amount or charge becomes due and payable and such
         failure continues for more than ten (10) days after Landlord gives
         written notice thereof to Tenant; provided, however, that after the
         second such failure in a calendar year, only the passage of time, but
         no further notice, shall be required to establish an Event of Default
         in the same calendar year; or

                  (iii) Tenant fails to perform or breaches any other agreement
         or covenant of this Lease to be performed or observed by Tenant as and
         when performance or observance is due and such failure or breach
         continues for more than ten (10) days after Landlord gives written
         notice thereof to Tenant; provided, however, that if, by the nature of
         such agreement or covenant, such failure or breach cannot reasonably be
         cured within such period of ten (10) days, an Event of Default shall
         not exist as long as Tenant commences with due diligence and dispatch
         the curing of such failure or breach within such period of ten (10)
         days and, having so commenced, thereafter prosecutes with diligence and
         dispatch and completes the curing of such failure or broach; or

                  (iv) Tenant (A) files, or consents by answer or otherwise to
         the filing against it of, a petition for relief or reorganization or
         arrangement or any other petition in bankruptcy or for liquidation or
         to take advantage of any bankruptcy, insolvency or other debtors'
         relief law of any jurisdiction, (B) makes an assignment for the benefit
         of its creditors, (C) consents to the appointment of a custodian,
         receiver, trustee or other officer with similar powers of Tenant or of
         any substantial part of Tenant's property, or (D) takes action for the
         purpose of any of the foregoing; or

                  (v) Without consent by Tenant, a court or government authority
         enters an order, and such order is not vacated within thirty (30) days,
         (A) appointing a custodian, receiver, trustee or other officer with
         similar powers with respect to Tenant or with respect to any
         substantial part of Tenant's property, or (B) constituting an order for
         relief or approving a petition for relief or reorganization or
         arrangement or any other petition in bankruptcy or for liquidation or
         to take


                                       11
<PAGE>

         advantage of any bankruptcy, insolvency or other debtors' relief law of
         any jurisdiction, or (C) ordering the dissolution, winding-up or
         liquidation of Tenant; or

                  (vi) This Lease or any estate of Tenant hereunder is levied
         upon under any attachment or execution and such attachment or execution
         is not vacated within thirty (30) days; or

                  (vii) Tenant intentionally abandons the Premises.

         (b) If an Event of Default occurs, Landlord shall have the right at any
time to give a written termination notice to Tenant and, on the date specified
in such notice, Tenant's right to possession shall terminate and this Lease
shall terminate. Upon such termination, Landlord shall have the right to recover
from Tenant:

                  (i) The worth at the time of award of all unpaid rent which
         had been earned at the time of termination;

                  (ii) The worth at the time of award of the amount by which all
         unpaid rent which would have been earned after termination until the
         time of award exceeds the amount of such rental loss that Tenant proves
         could have been reasonably avoided;

                  (iii) The worth at the time of award of the amount by which
         all unpaid rent for the balance of the term of this Lease after the
         time of award exceeds the amount of such rental loss that Tenant proves
         could be reasonably avoided; and

                  (iv) All other amounts necessary to compensate Landlord for
         all the detriment proximately caused by Tenant's failure to perform all
         of Tenant's obligations under this Lease or which in the ordinary
         course of things would be likely to result therefrom. The "worth at the
         time of award" of the amounts referred to in clauses (i) and (ii) above
         shall be computed by allowing interest at the maximum annual interest
         rate allowed by law for business loans (not primarily for personal,
         family or household purposes) not exempt from the usury law at the time
         of termination or, if there is no such maximum annual interest rate, at
         the rate of eighteen percent (18%) per annum. The "worth at the time of
         award" of the amount referred to in clause (iii) above shall be
         computed by discounting such amount at the discount rate of the Federal
         Reserve Bank of San Francisco at the time of award plus one percent
         (1%). For the purpose of determining unpaid rent under clauses (i),
         (ii) and (iii) above, the rent reserved in this Lease shall be deemed
         to be the total rent payable by Tenant under Paragraphs 3 and 4 hereof.

         (c) Notwithstanding the occurrence of an Event of Default, pursuant to
California Civil Code ss. 1954.1, or any successor statute thereof, this Lease
shall continue in effect for so long as Landlord does not terminate Tenant's
right to possession, and Landlord shall have the right to enforce all its rights
and remedies under this Lease, including the right to recover all rent as it
becomes due under this Lease. Acts of maintenance or preservation or efforts to
relet the Premises or the appointment of a receiver upon initiative of Landlord
to protect Landlord's interest under this


                                       12
<PAGE>

Lease shall not constitute a termination of Tenant's right to possession unless
written notice of termination is given by Landlord to Tenant.

         (d) The remedies provided for in this Lease are in addition to all
other remedies available to Landlord at law or in equity by statute or
otherwise.

         (e) All agreements and covenants to be performed or observed by Tenant
under this Lease shall be at Tenant's sole cost and expense and without any
abatement of Base Rental and Additional Charges. If Tenant fails to pay any sum
of money to be paid by Tenant or to perform any other act to be performed by
Tenant under this Lease, Landlord shall have the right, but shall not be
obligated, and without waiving or releasing Tenant from any obligations of
Tenant, to make any such payment or to perform any such other act on behalf of
Tenant in accordance with this Lease. All sums so paid by Landlord and all
necessary incidental costs shall be deemed Additional Charges hereunder and
shall be payable by Tenant to Landlord on demand, together with interest on all
such sums from the date of expenditure by Landlord to the date of repayment by
Tenant at the maximum annual interest rate allowed by law for business loans
(not primarily for personal, family or household purposes) not exempt from the
usury law at the date of expenditure or, if there is no such maximum annual
interest rate, at the rate of eighteen percent (18%) per annum. Landlord shall
have, in addition to all other rights and remedies of Landlord, the same rights
and remedies in the event of the nonpayment of such sums plus interest by Tenant
as in the case of default by Tenant in the payment of Base Rental.

         (f) If Tenant abandons or surrenders the Premises, or is dispossessed
by process of law or otherwise, any movable furniture, equipment, trade fixtures
or personal property belonging to Tenant and left in the Premises shall be
deemed to be abandoned, at the option of Landlord, and Landlord shall have the
right to sell or otherwise dispose of such personal property in any commercially
reasonable manner.

19.      Right of Landlord to Perform

         All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any abatement of Base Rental or Additional Charges. If
Tenant shall fail to pay any sum of money, other than Base Rental or Additional
Charges, required to be paid by it hereunder or shall fail to perform any other
act on its part to be performed hereunder, and such failure shall continue for
ten (10) days after notice thereof by Landlord, Landlord may, but shall not be
obligated to do so, and without waiving or releasing Tenant from any obligations
of Tenant, make any such payment or perform any such act on Tenant's part to be
made or performed as provided in this Lease. All sums so paid by Landlord and
all necessary incidental costs together with interest thereon at the maximum
rate permitted by law, from the date of such payment by Landlord shall be
payable as Additional Charges to Landlord on demand.


                                       13

20.      Notices

         Any notices under this Lease shall be effective only if given in
writing, sent by certified mail or delivered personally, (a) to Tenant (i) at
the address designated for such notices in the Basic Lease Information attached
hereto, if sent prior to Tenant's taking possession of the Premises, or (ii) at
the Premises if sent subsequent to Tenant's taking possession of the Premises,
or (iii) at any place where Tenant may be found if sent subsequent to Tenant's
vacating, deserting, abandoning or surrendering the Premises, and (b) to
Landlord at the address set forth in the Basic Lease Information, or (c) to such
other address as either Landlord or Tenant may designate as its new address for
such purpose by notice given to the other in accordance with the provisions of
this Paragraph 20. Any notice shall be deemed to have been given two (2) days
after the date when it shall have been mailed or upon the date personal delivery
is made. If Tenant is notified of the identity and address of any mortgagee,
Tenant shall give to such mortgagee notice of any default by Landlord under the
terms of this Lease in writing sent by certified mail, and such mortgagee shall
be given a reasonable opportunity to cure such default prior to Tenant's
exercising any remedy available to it.

21.      Quiet Enjoyment

         Upon the payment by Tenant of all Base Rental and Additional Charges
due hereunder, and upon performance by Tenant of all of the terms, covenants and
conditions on Tenant's part to be observed and performed, Tenant shall peaceably
and quietly hold and enjoy the Premises for the Term hereby demised, subject to
all of the terms, covenants and conditions of this Lease.

22.      Subordination and Attornment

         (a) This Lease shall be subject and subordinate at all times to the
lien of all mortgages and deeds of trust securing any amount or amounts
whatsoever which may now exist or hereafter be placed on or against the Building
or on or against Landlord's interest or estate therein, all without the
necessity of having further instruments executed by Tenant to effect such
subordination. Notwithstanding the foregoing, in the event of a foreclosure of
any such mortgage or deed of trust or of any other action or proceeding for the
enforcement thereof, or of any sale thereunder, this Lease shall not be
terminated or extinguished, nor shall the rights and possession of Tenant
hereunder be disturbed, if no Event of Default then exists under this Lease, and
Tenant shall attorn to the person or entity that acquires Landlord's interest
hereunder through any such mortgage or deed of trust. Tenant agrees to execute,
acknowledge and deliver upon demand such further instruments evidencing such
subordination of this Lease to the lien of all such mortgages and deeds of trust
as may reasonably be required by Landlord. Landlord shall use its reasonable
efforts to obtain a non-disturbance agreement from any current lender.

         (b) The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, shall not work a merger and shall, at the option of
Landlord, terminate all or any existing subleases or subtenancies or operate as
an assignment to Landlord of any or all such subleases or subtenancies.


                                       14
<PAGE>

         (c) If the original Landlord hereunder, or any successor owner of the
Building, sells or conveys the Building, all liabilities and obligations on the
part of the original Landlord, or such successor owner, under this Lease
accruing after such sale or conveyance shall terminate and the original
Landlord, or such successor owner, shall automatically be released therefrom,
and thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

23.      Tenant's Certificates

         From time to time upon not less than ten (10) days' prior written
notice from Landlord, Tenant will execute and deliver to Landlord a certificate
of Tenant stating: (a) that Tenant has accepted the Premises (or, if Tenant has
not done so, that Tenant has not accepted the Premises and specifying the
reasons therefor), (b) the Commencement and Expiration Dates of this Lease, (c)
that this Lease is unmodified and in full force and effect (or, that there have
been modifications), (d) whether or not there are then existing any defenses
against the enforcement of any of the obligations of Tenant under this Lease
(and, if so specifying same), (e) whether or not there are then existing any
defaults by Landlord in the performance of its obligations under this Lease
(and, if so, specifying same), (f) the dates, if any, to which the Base Rental
and Additional Charges under this Lease have been paid, and (g) any other
information that may reasonably be required by Landlord. It is intended that any
such certificate of Tenant delivered pursuant to this Paragraph 23 may be relied
upon by Landlord and any prospective purchaser or mortgagee of the Building or
any portion thereof. Tenant's failure to execute and deliver such certificate to
Landlord within ten (10) days of Landlord's written notice shall constitute a
certification by Tenant (i) that Tenant has accepted the Premises, (ii) that
there are no existing defenses against the enforcement of the obligations of
Tenant under the Lease, and (iii) that there are no existing defaults by
Landlord in the performance of its obligations under the Lease. In addition,
Tenant's failure to execute and deliver such certificate to Landlord with ten
(10) days of Landlord's written notice shall constitute a certification by
Tenant that the information required in (b), (c), (f) and (g) of this Paragraph
23 to be included in the certificate of Tenant is as indicated by Landlord in
writing to any prospective purchaser or mortgagee of any part of the Building or
the land upon which the Building is located, if such a writing is provided by
Landlord as a result of Tenant's failure to timely provide a tenant's
certificate pursuant to this Paragraph 23.

24.      Successors and Assigns

         Subject to the provisions of Paragraph 12, the terms, covenants and
conditions contained in this Lease shall be binding upon and inure to the
benefit of the parties hereto and their respective legal and personal
representatives, successors and assigns.

25.      Attorneys' Fees

         If either party defaults in the performance of any of the terms,
covenants and conditions of this Lease and by reason thereof the other party
employs the services of an attorney to enforce


                                       15
<PAGE>

performance of the covenants, or to perform any service based upon defaults,
then in any of said events the prevailing party shall be entitled to reasonable
attorneys' fees and all expenses and costs incurred by the prevailing party
pertaining thereto (including costs and fees relating to any appeal) and in
enforcement of any remedy.

26.      Waiver

         If either Landlord or Tenant waives the performance of any term,
covenant or condition contained in this Lease, such waiver shall not be deemed
to be a waiver of any subsequent breach of the same or any other term, covenant
or condition contained herein. Furthermore, the acceptance of Base Rental or
Additional Charges by Landlord shall not constitute a waiver of any preceding
breach by Tenant of any term, covenant or condition of this Lease, regardless of
Landlord's knowledge of such preceding breach at the time Landlord accepted such
Base Rental or Additional Charges. Failure by Landlord to enforce any of the
terms, covenants or conditions of this Lease for any length of time shall not be
deemed to waive or to decrease the right of Landlord to insist thereafter upon
strict performance by Tenant. Waiver by Landlord of any term, covenant or
condition contained in this Lease may only be made by a written document signed
by Landlord.

27.      Surrender of Premises

         At the end of the Term or sooner termination of this Lease, Tenant will
peaceably deliver to Landlord possession of the Premises, together with all
improvements or additions upon or belonging to same, by whomsoever made, in the
same condition as received or first installed, damage by fire, earthquake, Act
of God, or the elements alone excepted. Upon the termination of this Lease,
Tenant shall repair any damage caused by such removal. Property not so removed
shall be deemed abandoned by Tenant, and title to the same shall thereupon pass
to Landlord.

28.      Holding Over

         Any holding over after the expiration of the Term with the consent of
Landlord shall be construed to be a tenancy from month to month at a monthly
Base Rental equal to two hundred percent (200%) of the Base Rental for last
month of the Term of this Lease, and shall otherwise be on the terms and
conditions herein specified so far as applicable. Any holding over without
Landlord's consent shall constitute an Event of Default and entitle Landlord to
recover possession of the Premises in accordance with applicable law.

29.      Limitation of Liability

         Tenant agrees to look only to the equity of Landlord in the Premises
and not to Landlord personally with respect to any obligations or payments due
or which may become due from Landlord hereunder, and no other property or assets
of Landlord or any partner, joint venturer, officer, director, shareholder,
agent, or employee of Landlord, disclosed or undisclosed, shall be subject to
levy, execution or other enforcement procedure for the satisfaction of Tenant's
claims under or with


                                       16
<PAGE>

respect to this Lease, and no partner, officer, director, agent or employee of
Landlord shall be personally liable in any manner or to any extent under or in
connection with this Lease. If at any time the holder of Landlord's interest
hereunder is a partnership or joint venture, a deficit in the capital account of
any partner or joint venturer shall not be considered an asset of such
partnership or joint venture.

30.      Brokerage

         Tenant and Landlord each represents and warrants to the other that it
has dealt with no broker, agent or other person in connection with this
transaction and that no broker, agent or other person brought about this
transaction, other than the brokers set forth in the Basic Lease Information
attached hereto and Tenant and Landlord agree to indemnify and hold the other
harmless from and against any claims by any other broker, agent or other person
claiming a commission or other form of compensation by virtue of having dealt
with the indemnifying party with regard to this leasing transaction. The
provisions of this paragraph shall survive the expiration or termination of this
Lease.

31.      Invalidity of Provision

         If any term, provision, covenant or condition of this Lease or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease or the application of such
term, provision, covenant or condition to persons or circumstances other than
those as to which it is held invalid or unenforceable shall not be affected
thereby and each term, provision, covenant or condition of this Lease shall be
valid and be enforceable to the fullest extent permitted by law. This Lease
shall be construed in accordance with the laws of the State of California.

32.      Time of Essence

         It is understood and agreed between the parties that time is of the
essence of all the terms, provisions, covenants and conditions of this Lease.

33.      Entire Agreement

         This Lease contains the entire agreement between the parties hereto and
all previous negotiations leading thereto, and it may be modified only by an
agreement in writing signed by Landlord and Tenant. No surrender of the Premises
shall be valid unless accepted by Landlord in writing. Tenant acknowledges and
agrees that Tenant has not relied upon any statement, representation, prior
written or prior or contemporaneous oral promises, agreements or warranties
except such as are expressed herein.

         IN WITNESS WHEREOF, the parties hereto have executed this Lease as of
the date first above written.

Landlord the entire rentable portion of the eighth floor (the "Demised
Premises"), in the building known as 215 Park Avenue South, New York, New York
10003 (the "Building"), for a term (the "Term") to commence on July 1, 1999,
subject to obtaining the consent of the Prime Landlord pursuant to Article 16,

($32,500.00) Dollars per month, from the Commencement Date to December 31, 2002,
and Four Hundred Twenty Thousand ($420,000.00) Dollars, Thirty Five Thousand
($35,000.00) Dollars per month, from January 1, 2003 to December 30, 2006. If

consecutive monthly installments as set forth above in advance on the first day
of each calendar month during the Term, at Landlord's office hereinabove set

Simultaneously with the execution of this Sublease, Tenant has paid to Landlord
the first monthly installment of Fixed Rent, receipt of which, subject to
collection, is hereby acknowledged. Notwithstanding the foregoing if the Tenant
is not in material default of its obligations hereunder beyond applicable notice
and grace periods, it shall be entitled to a rental abatement of Fixed Rental
from the Commencement Date until November 30, 1999.

         2. (a) This Sublease is a sublease with respect to the Demised Premises
and is subject and subordinate to all of the terms, covenants and conditions of
that certain Agreement of Lease ("Prime Lease") made as of October 8, 1998
between 215 Park Avenue South Associates L.P. as Landlord ("Prime Landlord") and
Landlord, as tenant, a copy of which has been provided to Tenant, and which
Tenant acknowledges receipt of. Except as specifically provided in, and to the
extent not inconsistent with, the provisions of this Sublease, all of the terms,
covenants and conditions of the Prime Lease, except Articles 24, 32, 42, 43, 45,
and 48 thereof, shall be deemed incorporated herein. Notwithstanding the
foregoing the following Articles shall be incorporated as modified:

                  Article 49(A), Paragraph (ii) and all references to the ninth
                  floor are deleted.
                  Article 50(A)(3) - The multiplication factor shall be 15,000.
                  Article 51(A)(2) - The percentage shall be 5.17 percent and
                  the base year shall be the New York City 1999/2000 Tax Year.


                                       21
<PAGE>

                  Article 52(A)(vii) - The Tenant's share shall be 5.17 percent.

         As used in the Prime Lease, the term "Landlord" shall refer to Landlord
hereunder and the term "Tenant" shall refer to Tenant hereunder. Landlord
represents to Tenant that (i) the Prime Lease is in full force and effect and
has not been amended; (ii) the redacted copy of the Prime Lease presented to the
Tenant is a true copy of the original, except for the deleted portions; (iii) to
the best of Landlord's knowledge, neither Landlord or Tenant is in default under
the Prime Lease, and no condition exists to which with the giving of notice or
the passage of time, or both, would constitute a default under the Prime Lease;
and (iv) to the best of Landlord's knowledge, there are no New York City
Building Department violations or conditions which would give rise with the
passage of time to become such violations, encumbrances or liens affecting the
Demised Premises.

         (b) Tenant acknowledges that it has read and examined the Prime Lease
as redacted and is fully familiar with all of the terms, covenants and
conditions on the tenant's part to be performed thereunder. Tenant covenants and
agrees that, except for the payment of Fixed Rent and Additional Rent (as such
terms are defined in the Prime Lease), it will perform and observe all of the
terms, covenants and conditions contained in the redacted Prime Lease to be
performed and observed on the part of the "Tenant" thereunder during the term of
this Sublease insofar as they relate to the Demised Premises, other than the
redacted portions hereof, and any default by Tenant in the performance or
observance of such terms, covenants and conditions of the Prime Lease shall be
deemed a default under this Sublease. Tenant will and does hereby indemnify and
hold Landlord harmless from and against any and all actions, claims, demands,
damages, liabilities and expenses (including, without limitation, reasonable
attorney's fees) based upon, or incurred on account of, any violation of such
terms, covenants and conditions caused suffered or permitted by Tenant, its
agents, servants, employees or invitees. Landlord hereby agrees to pay the Fixed
Rent and Additional Rent, if any, when due and otherwise comply with the
provisions of the Prime Lease which are not the Tenant's obligations under this
Sublease. A failure of the Landlord hereunder to make any payment of fixed rent
or additional rent due the Prime Landlord under the Prime Lease shall be deemed
a breach hereunder, and the Tenant shall be allowed to make the appropriate
payments to the Prime Landlord. If any payment made to the Prime Landlord by
Tenant exceeds the payments due hereunder, Landlord shall reimburse Tenant
within ten (10) business days of the demand for payment by Tenant. Tenant shall
be further entitled to cure Landlord's non-monetary defaults under the Prime
Lease. Landlord hereby agrees to indemnify Tenant against all cost, expenses and
claims, including reasonable attorneys fees, with reference to any claims by the
Manhattan Studio Architect & Design, P.C. with references to professional
services provided by them to Landlord regarding either the eighth or ninth
floors of the Building.

         3. Tenant shall use and occupy the Demised Premises for general
executive and administrative offices in connection with Tenant's business and
for no other purpose.

         4. (a) Simultaneously with the execution of this Sublease, Tenant shall
deposit with Landlord the sum of $135,000.00, as security for the full and
faithful performance and


                                       22
<PAGE>

observance by Tenant of the terms, provisions, covenants and conditions of this
Sublease on Tenant's part to be performed and observed. In the event the Tenant
is not in default of any of its obligations hereunder on January 1, 2003, after
any applicable notice and cure periods, Tenant shall be entitled to refund of
$65,000.00 of the security deposit, and one half of the accrued interest, or to
replace the existing letter of credit, as hereinafter provided, with a letter of
credit in the sum of $70,000.00.

                  (b) Landlord shall deposit such funds in an interest bearing
account for the benefit of Tenant, with accrued interest to be retained with the
security deposit for the benefit of the Tenant, provided however Landlord shall
be entitled to retain one (1%) one percent of the security deposit annually as
an administrative fee.

                  (c) In lieu of maintaining a cash deposit as previously
described Tenant may establish and maintain during the term hereof an clean,
unconditional, irrevocable letter of credit in the amount specified. The letter
of credit shall be issued by a New York Clearing House Bank and shall be in a
form reasonably acceptable to Landlord for a period extending thirty (30) days
after the conclusion of the term hereof. Such letter of credit shall provide,
among other provisions, that it shall be drawable, either in partial draws or in
a single draw for the full amount, at the same time(s) and the same amount(s) as
the cash deposit might be applied by Landlord pursuant to the provisions of this
Article. If at any time the total of the undrawn amount(s) of the letter of
credit and any cash deposits then held by Landlord shall be less than the amount
specified in Article 4 (a) hereof, then Tenant shall immediately deposit with
the Landlord an additional letter of credit or an additional cash deposit equal
to such deficiency. Said letter shall be for successive terms of not less than
one year and shall be automatically be renewed unless the issuing bank shall
give Landlord notice thereof not less than thirty (30) days before the
expiration of the then current term. In the event Landlord receives notice of
non-renewal of the letter of credit it shall be entitled to draw and retain as a
cash security deposit the entire then current balance.

                  (d) Landlord may use, apply or retain the whole or any part of
the security deposit to the extent required for the payment of any Fixed Rent or
any other sum as to which Tenant is in default, after any applicable notice and
cure periods, 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, provisions,
covenants and conditions of this Sublease, including, but not limited to, any
damages or deficiency in the reletting of the Demised Premises, whether such
damages or deficiency accrued before or after summary proceedings or other
re-entry of Landlord. In the event that Tenant shall fully and faithfully comply
with all of the terms, provisions, covenants and conditions of this Sublease,
the security deposit, or so much thereof as shall not have been applied by
Landlord as aforesaid, shall be returned to Tenant promptly after the Expiration
Date (or earlier termination date) and after delivery of entire possession of
the Demised Premises to Landlord. In the event of an assignment by Landlord of
its interest under the Prime Lease, Landlord shall have the right to transfer
the security deposit to the assignee and Landlord shall thereupon be released by
Tenant from all liability for the return of such security deposit provided that
the Assignee shall assume the obligation to maintain the Security Deposit in
accordance with


                                       23
<PAGE>

the terms and conditions of this Sublease. In such event, Tenant shall look
solely to the new landlord or any subsequent transferee for the return of said
security deposit. Tenant further covenants that it will not assign or encumber
or attempt to assign or encumber the security deposit and that neither Landlord
nor it successors or assigns shall be bound by any such assignment, encumbrance,
attempted assignment or attempted encumbrance.

         5. In the event that Tenant shall default in the full performance of
any of the terms, provisions, covenants and conditions on its part to be
performed under this Sublease following the notice and any applicable grace
procedures in the Prime Lease, then Landlord shall have the same rights and
remedies with respect to such default as are given to the Prime Landlord under
the Prime Lease with respect to defaults by the "Tenant" under the Prime Lease,
all with the same force and effect as though the provisions of the Prime Lease
with respect to defaults and the rights and remedies under the Prime Lease in
the event thereof were set forth at length herein. Notwithstanding anything to
the contrary contained in the Prime Lease and without limiting the generality of
the preceding sentence, if Tenant fails to surrender possession of the Demised
Premises on the Expiration Date or such earlier date as this Lease may be
terminated, (i) Landlord shall be entitled to all of the rights and remedies
which are available to a landlord against a tenant holding over after the
expiration of a term and to such other rights and remedies as may be provided
for in this Sublease, the Prime Lease, at law or in equity and (ii) Tenant, at
Landlord's option, shall be deemed to be occupying the Demised Premises as a
tenant from month to month, at a monthly rental equal to the greater of (a) two
times (2x) the Fixed Rent and Additional Rent payable during the last full
calendar month immediately preceding the expiration or termination of this
Sublease or (b) all loss, cost, liability and expense (including actual
attorneys fees and disbursements) suffered or incurred by Landlord, as a result
of Tenant's occupancy of the Demised Premises after the Expiration Date and
including, without limitation, damages or costs of any kind paid or payable by
Landlord to Prime Landlord or any third party, with respect to the entire
premises of which the Demised Premises are a part but excluding any loss caused
solely by the holding over of any other subtenant or assignee in the balance of
Landlord's space.

         6. (a) Tenant shall have and enjoy the same rights to have facilities
and services furnished by Prime Landlord as Landlord possesses under the
provisions of the Prime Lease. Landlord agrees that if at any time during the
Term such facilities or services are not furnished or are improperly furnished
to Tenant, then, upon receipt of written notice from Tenant specifying such
failure, Landlord shall use its reasonable efforts to cause such facilities
and/or services to be resumed or properly furnished or performed by Prime
Landlord insofar as the same apply to or affect the Demised Premises, provided
that Prime Landlord's failure to furnish and/or perform such facilities or
service does not result from anything done or permitted to be done by Tenant
which would excuse Prime Landlord from the furnishing or performance thereof. If
Landlord shall commence litigation in order to obtain any such work, facilities,
services or duties for Tenant, which litigation Tenant may join, and whether or
not it so joins, Tenant shall pay all reasonable costs and expenses (including
attorney's fees) incurred in connection therewith. No such litigation shall be
commenced without Tenant's prior written approval. The failure of Landlord to
cause any such facilities and/or services to be resumed or properly furnished or


                                       24
<PAGE>

performed shall in no event (unless Prime Landlord's failure is a result of
Landlord's default under the Prime Lease) excuse Tenant from the full
performance of all of the terms, provisions, covenants and conditions of this
Lease on the part of Tenant to be performed, including, without limitation,
Tenant's obligation to pay Fixed Rent and Additional Rent. Notwithstanding the
foregoing, if Landlord is entitled to an abatement of rent from the Prime
Landlord due to the failure of the Prime Landlord supply facilities and/or
services, then Tenant shall be entitled to a prorata abatement of Fixed and
Additional Rent due hereunder.

                  (b) Notwithstanding anything, in the Prime Lease or this
Sublease to the contrary, Tenant covenants and agrees that Landlord shall not be
obligated to perform any services of any nature whatsoever (including, without
limitation, the furnishing of heat, electrical energy, water, air cooling or air
conditioning, elevator service, window washing or rubbish removal services), nor
shall Landlord be obligated to make any repairs, alterations or improvements in
and about the Demised Premises, other than as expressly set forth in this
Sublease, or to comply with any violations of law in respect thereto, nor shall
Landlord be required to restore the Demised Premises following the occurrence of
a fire or other casualty, or to perform any other duty respecting the Demised
Premises which Prime Landlord is required to perform under the Prime Lease, nor
shall Landlord be liable to Tenant under any representation or warranty made by
the Prime Landlord in the Prime Lease, it being understood, and Tenant hereby so
agrees, that Tenant shall look solely to Prime Landlord, for the performance of
any and all such services or work, the making of repairs, alterations or
improvements, elimination or correction of violations of law, the restoration of
the Demised Premises following fire or other casualty, the performance of other
duties of Prime Landlord and compliance with all such representations and
warranties, subject in each case to the terms of the Prime Lease and this
Sublease. Landlord agrees to cooperate with Tenant, in the event that Tenant
wishes to assert a claim against Prime Landlord in Tenant's name or in
Landlord's name, it being understood and agreed that Tenant shall have the right
to make such a claim on Landlord's behalf, provided, however that Tenant shall
reimburse Landlord for any reasonable expenses Landlord may incur, and further
provided, that Tenant shall submit copies of all documents regarding any claim
to Landlord for its approval before sending the same to Prime Landlord.
Landlord's approval will not be unreasonably withheld or delayed.

         7. Tenant has made a thorough inspection of the Demised Premises and is
familiar with the condition thereof. Tenant agrees that neither Landlord nor any
agent, representative or employee of Landlord has made any representations or
warranties whatsoever with respect to the Demised Premises other than as
contained herein. Tenant agrees to accept the Demised Premises "as is" without
requiring any alterations, improvements, repairs or decorations to be made by
Landlord or at Landlord's expense, either at the time possession is given to
Tenant or any other time during the term of this Sublease, provided however that
Landlord represents that the air conditioning units servicing the Premises will
be in good working at the commencement of the lease term and prior to the
commencement of the Lease Term, Landlord will supply Tenant with an ACP-5
Certificate regarding asbestos in the Premises. Tenant may not make any physical
alterations to the Premises without the prior written consent of the Prime
Landlord, as provided for in the Prime Lease. Tenant shall submit any request
for approval to an alteration to the


                                       25
<PAGE>

Landlord, who shall immediately forward the request to the Prime Landlord. A
consent by the Prime Landlord to a proposed alteration shall be deemed to be a
consent by the Landlord.

         8. Notwithstanding anything to the contrary contained in the Prime
Lease or this Sublease, Tenant shall not assign, mortgage or encumber this
Sublease or any of its rights or interest hereunder, nor sublet the Demised
Premises or any part thereof without the Landlord's prior written consent which
consent may not be unreasonably withheld. Tenant shall not permit the Demised
Premises or any part thereof to be used or occupied by anyone other than the
officers, directors and employees of Tenant without such consent. Where required
under the Prime Lease, Prime Landlord's consent shall be obtained.

         9. Any notice, demand, request, consent or other communication
