cure said default with the same effect as if cured by Landlord, and if
necessary, enter upon the Premises for the purpose of curing any such default,
provided that the mortgagee or ground lessor must cure the default within the

of any such notice to Landlord shall not be properly given under the terms of
this Lease and shall not be of any force and effect until a duplicate copy
thereof shall also have been given to the mortgagee or ground lessor pursuant to

to that time Tenant vacates the Premises, to decorate, remodel, repair, alter or
otherwise prepare the Premises for reoccupancy, including the placing of a

<PAGE>

22.02 - Limitation on Personal Liability
----------------------------------------

          (a) It is understood and agreed that Tenant shall look solely to the
estate and property of Landlord in the Building for the satisfaction of Tenant's
remedies for the collection of a judgment (or other judicial process) requiring
the payment of money by Landlord in the event of any default or breach by
Landlord with respect to any of the terms, covenants and conditions of this
Lease to be observed and/or performed by Landlord and any other obligation of
Landlord created by or under this Lease and no other property or assets of
Landlord or of its partners, beneficiaries, co-tenants, shareholders, or
principals (as the case may be) shall be subject to levy, execution or other
enforcement procedures.

          (b) The term "Landlord," as used in subparagraph 22.02(a) above and
throughout this Lease, so far as covenants and agreements on the part of the
Landlord are concerned, shall be limited to mean and include only the owner or
owners at the time in question of the Building and Lease.  Further, in the event
of any transfer or transfers of the title to the said Lease and/or the Building,
Landlord herein named (and in case of any subsequent transfers or conveyances,
the then grantor), including each of its partners, beneficiaries, co-tenants,
shareholders, or principals (as the case may be), shall be automatically freed
and relieved from and after the date of such transfer and conveyance of all
liability as respects the performance of any covenants and agreements on the
part of Landlord.  Landlord or the grantor shall turn over to the grantee all
monies and security, if any, then held by Landlord or such grantor on behalf of
Tenant and shall assign to such grantee all right, title and interest of

agreements contained in this Lease on the part of Landlord to be performed

22.04 - Lease Binding

          All covenants in this Lease which are binding upon Tenant shall be
construed to be equally applicable to and binding upon Tenant's agents,
employees and others claiming the right to be in the Premises or in the Building
through or under Tenant.

          If more than one individual, firm or corporation shall join as Tenant,
the singular context shall be construed to be plural wherever necessary and the
covenants of Tenant shall be the joint and several obligations of each party
signing as Tenant, and, when the parties signing as Tenant are partners, shall
be the joint and several obligations of the firm and of the individual members
thereof.

22.05 - Vaults, Vault Space, Etc.
---------------------------------

          No vaults, vault space or space not within the property line of the
Building is leased hereunder, anything contained in or indicated on any sketch,
blueprint or plan, or anything contained elsewhere in this Lease to the contrary
notwithstanding.  Landlord makes no representations as to the location of the
property line of the Building.  All vaults and vault space and all space 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 be diminished or
required by any Federal, State, 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 constructive or actual eviction.  Any fee or
charge of municipal authorities for such vault shall be paid by Tenant.

22.06 - Failure to Give Possession
----------------------------------

          If Landlord shall not be able to turn space over substantially
completed to Tenant by October 1, 1999, then for each day of delay of
substantial completion Tenant shall receive three (3) additional days of rent
abatement.

22.07 - Force Majeure
---------------------

          The period of time during which either party is prevented or delayed,
in the performance or the making of any improvements or repairs or fulfilling
any obligation other than the payment of fixed monthly rent or additional rent
required under this Lease due to unavoidable delays caused by fire, catastrophe,
strikes or labor trouble, civil commotion, Acts of God or the public enemy,
governmental prohibitions or regulation or inability to obtain materials by
reason thereof, or other causes beyond such party's reasonable control, shall be
added to such party's time for performance thereof, and such party shall have no
liability by reason thereof.

22.08 - Attornment by Tenant
----------------------------

          If at any time during the term of this Lease Landlord hereunder shall
be the holder of a leasehold estate covering premises which include the Premises
and if such leasehold estate shall be canceled or otherwise terminated prior to
the expiration date thereof and prior to the expiration of the term of this
Lease or in the event of the surrender thereof whether voluntary, involuntary or
by operation of law, Tenant shall make full and complete attornment to the
lessor of such leasehold estate for the balance of the term of this Lease upon
the same covenants and conditions as are contained herein so as to establish
direct privity between such lessor and Tenant and with the same force and effect
as though this Lease was made directly from such lessor to the Tenant.  Tenant
shall make all rent payments thereafter directly to such lessor.  In the event
any proceedings are brought for the foreclosure of, or in the event of
conveyance by deed in lieu of foreclosure of, or in the event of exercises of
the power of sale under any mortgage or deed of trust made by Landlord covering
the leases Premises, or in the event Landlord sells, conveys or otherwise
transfers its interest in the Building or any portion thereof containing the
leased Premises, Tenant shall attorn to and hereby

                                       19
<PAGE>

covenants and agrees to execute an instrument in writing reasonably satisfactory
to the new owner whereby Tenant attorns to such successor in interest and
recognizes such successor as the Landlord under this Lease.

22.09 - Landlord May Pay Tenant's Obligations
---------------------------------------------

          All costs and expenses which Tenant assumes or agrees to pay under the
provisions of this Lease shall at Landlord's election be treated as additional
rent, and in the event of nonpayment, Landlord shall have all the rights and
remedies herein provided for in case of nonpayment of rent or of a breach of
covenant.  If Tenant shall default, beyond the applicable notice and cure
period, in making any payment required to be made by Tenant (other than the
payment of rent as provided by Article 3 above) or shall default in performing
any term, covenant or condition of this Lease on the part of Tenant to be
performed which shall involve the expenditure of money by Tenant, Landlord at
Landlord's option may, but shall not be obligated to, make such payment or, on
behalf of Tenant, expend such sum as may be necessary to perform and fulfill
such term, covenant or condition, and any and all sums so expended by Landlord,
with interest thereon at the rate of one and one-half percent (1-1/2%) per month
from the date of such expenditure, shall be and be deemed to be additional rent,
in addition to the rent provided in Article 3 and shall be repaid by Tenant to
Landlord on demand, but no such payment or expenditures by Landlord shall be
deemed a waiver of Tenant's default nor shall it affect any other remedy for
Landlord by reason of such default.

any such proposed modification or termination without said mortgagee's consent
shall be void as against said mortgagee.

22.16 - Complete Agreement
--------------------------

          This Lease contains and embraces the entire Agreement between the
parties hereto and it or any part of it may not be changed, altered, modified,
limited, terminated, or extended orally or by any agreement between the parties
unless such agreement be expressed in writing, signed and acknowledged by the
parties hereto, their legal representative, successors or assigns, except as may
be expressly otherwise provided herein.

22.17 - Invalidity of Particular Provisions
-------------------------------------------

          If any term or provision of this Lease or the application thereof to
any person or circumstances shall to any extent, be invalid or unenforceable,
the remainder of this Lease, or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby and each term and provision of this
Lease shall be valid and be enforced to the fullest extent permitted by law.

22.18 - Execution of Lease by Landlord
--------------------------------------

          The submission of this document for examination and negotiation does
not constitute an offer to lease, or a reservation of, or option for, the
Premises and this document becomes effective and binding only upon the execution
and delivery hereof by Landlord and by Tenant.  All negotiations,
considerations, representations and understandings between Landlord and Tenant
are incorporated herein and may be modified or altered only by agreement in
writing between Landlord and Tenant, and no act or omission of any employee or
other agent of Landlord shall alter, change or modify any of the provisions
hereof.

agent or of partnership or of joint venture between the parties hereto, it being

other provision herein contained, nor any acts of the parties hereto, shall be
deemed to create any relationship between the parties hereto other than Landlord
and Tenant.

          Tenant shall have two (2) consecutive five (5) year lease renewal

of recognized responsibility which are licensed to do business in the State of
New York.

which is usable by Tenant.  If the Building shall be so damaged that in the
opinion of Landlord the Building should not be restored or the Building should
be restored in such a way as to alter the Premises materially, Landlord may

        (a)  In the event that any part of the Premises shall be condemned or
taken in any manner for any public or quasi-public use, at the option of
Landlord, or automatically if the whole of the Premises be so taken, this Lease
shall forthwith cease and terminate as of the date when possession of the

of vesting of title.

                       ARTICLE 13 - Landlord's Remedies

13.01 - Conditional Limitations and Events of Default

        This Lease and the demised term are subject to the limitation that if,
at any time prior to or during the term, any one or more of the following events
(herein called an "event of default") shall occur, that is to say:

        (a)  If Tenant shall make an assignment for the benefit of its
        creditors; or

        (b)  If the leasehold estate hereby created shall be taken on execution
        or by other processes of law;

        (c)  If any petition shall be filed against Tenant in any bankruptcy,
        reorganization, composition, extension, arrangement, or insolvency
        proceedings, and Tenant shall thereafter be adjudicated bankrupt, or
        such petition shall be approved by the court, or the court shall

                                      -10-
<PAGE>

        assume jurisdiction of the subject matter and if such proceedings shall
        not be dismissed within ninety (90) days after the institution of the
        same; or if any such petition shall be so filed by the Tenant; or

        (d)  If in any proceedings a receiver or trustee be appointed for
        Tenant's property, and such receivership or trusteeship shall not be
        vacated or set aside within ninety (90) days after the appointment of
        such receiver or trustee; or

        (e)  If there is a transfer or attempted transfer of this Lease or of
        Tenant's interest therein or any sublease of the Premises or any portion
        thereon in violation of the restrictions set forth in this Lease; or

        (f)  If Tenant shall fail to pay any installment of the fixed monthly
        rent, or additional rent or any portion thereof when the same shall
        become due and payable, and such failure shall continue for ten (10)
        days after written notice from Landlord; or

        (g)  If Tenant shall vacate or abandon the Premises and permit same to
        remain unoccupied or closed for business (other than temporarily in
        connection with making permitted repairs or alterations); or

        (h)  If Tenant shall fail to perform or observe any other requirement of
        this Lease (not hereinbefore in this paragraph specifically referred to)
        on the part of Tenant to be performed or observed, and such failure
        shall continue for twenty (20) days after written notice thereof from
        Landlord to Tenant;

then, upon the happening of any one or more of the aforementioned events of
default, Landlord may give Tenant a notice (hereinafter called "notice of
termination") of its intention to end the term of this Lease at the expiration
of five (5) days from the date of service of such notice of termination, and at
the expiration of such five (5) days, this Lease and the term hereof, as well as
all of the right, title and interest of Tenant hereunder, shall wholly cease and
expire in the same manner and with the same force and effect as if the date of
expiration of such five (5) day period were the date originally specified herein
for the expiration of the demised term of this Lease, and Tenant shall then quit
and surrender the Premises to Landlord, but Tenant shall remain liable as herein
provided.

13.02 - Landlord's Remedies

        (a)  If this Lease shall be terminated as in Section 13.01 provided,
Landlord or Landlord's agents or employees may immediately or at any time
thereafter re-enter the Premises and remove therefrom Tenant, its agents,
employees, licensees, and any subtenants and other persons, firms or
corporations, and all or any of its or their property therefrom either by
summary dispossess proceedings or by any suitable action or proceeding at law or
by force, self-help or otherwise, without being liable to indictment,
prosecution or damages therefor, and repossess and enjoy said Premises, together
with all alterations, additions and improvements thereto.  Landlord, in the
event

                                      -11-
<PAGE>

of such re-entry and repossession, may store Tenant's property in a public
warehouse or elsewhere at the cost of and for the account of Tenant.

        (b)  In case of any such termination, re-entry or dispossess by summary
proceedings or otherwise, the rents and all other charges required to be paid up
to the time of such termination, re-entry or dispossess, shall be paid by Tenant
and Tenant shall also pay to Landlord all expenses which Landlord may then or
thereafter incur for legal expenses, attorney's fees, brokerage commissions and
all other costs paid or incurred by Landlord for restoring the Premises to good
order and condition and for altering and otherwise preparing the same for
reletting and for reletting thereof. Landlord may, at any time and from time to
time, relet the Premises, in whole or in part, for any rental then obtainable
either in its own name or as agent of Tenant, for a term or terms which, at
Landlord's option, may be for the remainder of the then current term of this
Lease or for any longer or shorter period.

        (c)  If this Lease be terminated as aforesaid, Tenant nevertheless
covenants and agrees notwithstanding any entry or re-entry by Landlord, whether
by summary proceedings, termination or otherwise, to pay and be liable for on
the days originally fixed herein for the payment thereof, the installments of
fixed monthly rent, additional rent and other charges, as under the terms of
this Lease would become due if this Lease had not been terminated or if Landlord
had not entered or re-entered as aforesaid, and regardless whether the Premises
be relet or remain vacant in whole or in part. In the event the Premises be
relet by the Landlord, Tenant shall be entitled to a credit (but not in excess
of the rent or other charges reserved under the terms of this Lease) in the net
amount of rent received by Landlord in reletting the Premises after deduction of
all expenses and costs incurred in reletting the Premises and in collecting the
rent in connection therewith. As an alternative, at the election of Landlord,
Tenant shall pay to Landlord as damages such a sum as at the time of such
termination represents the amount of excess, if any, of the then present value
of the total fixed monthly rent, additional rent and other benefits which would
have accrued to Landlord under the Lease for the remainder to the Lease term, if
the Lease terms had been fully complied with by Tenant, over and above the then
present rental value of the Premises for the balance of the term. Suit or suits
for the recovery of an deficiency or damages or for any installments or
installments of fixed monthly rent, additional rent or other charges hereunder,
or for a sum equal to any such installment or installments, may be brought by
Landlord at once or from time to time at Landlord's election and nothing in this
Lease shall be deemed to require Landlord to await the date whereon this Lease
or the term hereof would have expired by limitation had there been no such
default by Tenant or no such cancellation or termination.

        (d)  Tenant hereby expressly waives, so far as permitted by law, the
service of any notice of intention to re-enter provided for in any statute, or
of the institution of legal proceedings to that end, and Tenant, for and on
behalf of itself and all persons claiming through or under Tenant, also waives
any and all right of redemption or re-entry or repossession under present or
future laws, including specifically but without limitation Section 761 of the
New York Real Property Action and Proceedings Law including any amendments
hereafter. As an inducement to Landlord to make this Lease and in consideration
thereof, the Landlord and Tenant covenant and agree that in any action or
proceeding brought by either Landlord or Tenant against the other or any matter
whatsoever

                                      -12-
<PAGE>

arising out of, or by virtue of the terms of this Lease or of Tenant's
occupancy, Landlord and Tenant shall and do hereby waive trial by jury. In the
event Landlord commences any proceedings for non-payment of rent, Tenant shall
not interpose any non-compulsory counterclaim in any such proceeding. This shall
not, however, be construed as a waiver of Tenant's rights to assert such claim
in any separate action or actions initiated by Tenant.

        (e)  No failure by Landlord to insist upon the strict performance of any
covenant, agreement, term or condition of this Lease or to exercise any right or
remedy consequent upon a breach thereof, and no acceptance of full or partial
rent during the continuance of any such breach, shall constitute a waiver of any
such breach or of such covenant, agreement, term or condition.  No waiver of any
breach shall affect or alter this Lease, but each and every covenant, agreement,
term and condition of this Lease shall continue in full force and effect with
respect to any other then existing or subsequent breach thereof.  No payment by
Tenant or receipt by Landlord of a lesser amount than the monthly installments
of rent or additional rent stipulated in this Lease shall be deemed to be other
than on account of the earliest amounts due nor shall any endorsement or
statement on any check or letter accompanying a check for payment of rent be
deemed any accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
additional rent or to pursue any other remedy provided by this Lease.

        (f)  Tenant hereby grants to Landlord a security interest in all
equipment, fixtures, improvements, merchandise, now or hereafter located in the
Premises, and all proceeds therefrom, to secure the payment and performance of
the Tenant's obligations set forth in this Lease. Upon request, Tenant agrees to
sign a Financing Statement simultaneously with the execution and delivery of
this Lease or at any time thereafter, and Landlord is hereby authorized to file
such Financing Statement as may be required under the Uniform Commercial Code to
perfect such security interest. Upon the occurrence of any "event of default",
pursuant to Section 13.01 hereof, Landlord shall be entitled to exercise all of
the rights and remedies of a secured party under the Uniform Commercial Code.
Reasonable attorney fees of the Landlord in enforcing any right or exercising
any remedy under this Security Agreement shall be deemed a part of the
obligations secured hereby.

        (g)  In the event of any breach or threatened breach by Tenant of any of
the covenants, agreements, terms or conditions contained in this Lease, Landlord
shall be entitled to enjoin such breach or threatened breach and shall have the
right to invoke any right and remedy allowed at law or in equity, by statute or
otherwise.

        (h)  Each right and remedy of Landlord provided for in this Lease shall
be cumulative and shall be in addition to every other right or remedy provided
for in this Lease or now or hereafter existing at law or in equity, by statute
or otherwise.

14.01 - Mechanics' Liens

                                      -13-
<PAGE>

        If any mechanics' lien shall be filed against the Premises, the Building
or any portion thereof based upon any act of Tenant or anyone claiming through
Tenant, Tenant after notice thereof from Landlord (or any person in privity of
estate with Landlord) forthwith shall commence such action by bonding, deposit,
payment or otherwise, as will remove or satisfy such lien within fifteen (15)
days. In the event Tenant does not remove or satisfy said lien within said
fifteen (15) day period, Landlord shall have the right to do so by posting a
bond or undertaking, and Tenant agrees to reimburse Landlord for any and all
expenses incurred by Landlord in connection therewith five (5) days after
receipt by Tenant of Landlord's invoice therefor. These expenses include, but
are not limited to filing fees, legal fees and bond premiums.

        However, nothing in this Article 14 shall be deemed or construed as (a)
Landlord's consent to any person, firm or corporation for the performance of any
work or services or the supply of any materials to the Premises or any
improvement thereon, or (b) giving Tenant or any other person, firm or
corporation any right to contract for or to perform or supply any work, services
or materials that would permit or give rise to a lien against the Premises or
any part thereof.

         ARTICLE 15 - Assignments, Subleases and Transfers of Tenant's
                                   Interests

15.01 - Limitation on Tenant's Rights

        Neither this Lease nor any interest of Tenant therein shall be sold,
assigned, transferred, mortgaged, pledged, hypothecated or otherwise disposed
of, nor shall the Premises or any part thereof be sublet or occupied by other
than Tenant, whether by act of Tenant, or by operation of law, or otherwise,
without the prior written consent of Landlord in each instance.

        It is understood and agreed between the parties that, should Tenant
request Landlord's consent to a proposed assignment of this Lease or a
subletting of all or any portion of the Premises, Landlord will, in addition to
any other requirements which may be imposed as conditions to Landlord's consent,
require that Tenant execute and deliver to Landlord an agreement whereby Tenant
obligates itself, as additional rent, to pay over to Landlord the amount, if
any, of all rent, additional rent and any other consideration paid by such
assignee or sublessee to Tenant pursuant to such assignment or sublease which is
in excess of rent and additional rent due and payable from time to time from
Tenant to Landlord pursuant to this Lease.

        No consent by Landlord to an assignment of this Lease and no assignment
made, shall be effective until there shall have been delivered to Landlord an
agreement, in recordable form, executed by Tenant and the proposed assignee,
wherein and whereby such assignee assumes due performance of the obligations on
Tenant's part to be performed under this Lease to the end of the term hereof.

        Any assignment, mortgage, pledge, or hypothecation of these lease, or of
any interest of Tenant hereunder, and any sublease affecting the Premises shall
be subject to the full terms and conditions of this Lease.  Regardless of the
assumption by an assignee of due performance, the

                                      -14-
<PAGE>

Tenant named herein shall continue to be fully responsible for the due
performance of Tenant's obligations under this Lease in the same manner and to
the same extent as if no such assignment had been made.

        Any assignment, mortgage, pledge, or hypothecation of this Lease, or of
any interest of Tenant hereunder, or any sublease affecting the Premises shall
be subject and subordinate to the full terms and conditions of this Lease.
Regardless of the assumption by an assignee of due performance, the Tenant named
herein shall continue to be fully responsible for the due performance of
Tenant's obligations under this Lease in the same manner and to the same extent
as if no such assignment had been made.

        Any assignment, mortgage, pledge, or hypothecation of this Lease, or of
any interest of Tenant hereunder, or any sublease affecting the Premises,
without full compliance with all of the requirements set forth in this Lease,
shall be a breach of this Lease and an event of default hereunder.

15.02 - Landlord's Consent

        Any consent by Landlord to a sale, assignment, sublease, mortgage,
pledge, hypothecation, or transfer of this Lease, shall apply only to the
specific transaction thereby authorized and shall not relieve Tenant from the
requirement of obtaining prior written consent of Landlord to any further sale,
assignment, sublease, mortgage, pledge, hypothecating, or transfer of this
Lease.

        With respect to any of the consents requested by Tenant under the
provisions of this Article 15, whether or not the Landlord shall have consented
thereto, Tenant shall pay to the Landlord all reasonable counsel fees and other
out-of-pocket expenses incurred by the Landlord in connection therewith.

          ARTICLE 16 - Subordination of Lease and Mortgagee's Rights

16.01 - Subordination

        This Lease and all of the rights and interests of Tenant under this
Lease shall be subject and subordinate to any ground or underlying lease and to
any mortgage, whether fee or leasehold mortgage, now or hereafter affecting the
Premises or the Building or the land under the Building, and to any advances
made thereunder, and to the interest thereon, and to any renewal, modification,
consolidation, replacement, extension or refinancing thereof.

16.02 - Mortgagee's Rights

        (a) So long as any ground lease or mortgage shall remain a lien on the
Premises, the Building, or the land under the Building, Tenant agrees that
simultaneously with the giving of any

                                      -15-
<PAGE>

notice to Landlord which is required to be given by this Lease Tenant shall give
a duplicate copy thereof to the ground lessor or mortgagee. Further, Tenant
agrees that if Landlord defaults in its performance of any of the covenants
under the Lease, the ground lessor or mortgagee may cure said default within a
reasonable period of time beyond any time period permitted of Landlord, and if
necessary be permitted entry upon the Premises for the purpose of curing any
such default, all with the same effect as if cured by Landlord. The giving of
any such notice to Landlord shall not be properly given under the terms of this
Lease and shall be of no force and effect until a duplicate copy thereof shall
also have been given to the ground lessor or mortgagee pursuant to this Section
16.02.

        (b) The parties hereto mutually agree that so long as a mortgage shall
be a lien upon the Premises, they will not reduce the rents from that provided
for in this Lease, provide for payments of rents prior to the time herein
provided for, nor terminate this lease prior to the end of the term, except as
otherwise expressly provided in this Lease, without first obtaining the consent
of the mortgagee in writing, and that any such proposed modifications or
terminations without said mortgagee's consent shall be void as against said
mortgagee.

        (ii)   making any repairs to the Premises or the Building Common
        Facilities located in the Premises, or performing any work in the
        Premises that may be necessary by reason of Tenant's default under the
        terms of this Lease;

        (iii)  exhibiting the Premises for the purpose of sale, ground lease,

        Any notice, statement, certificate, request or demand required or

request or demand shall be deemed to have been given on the date mailed as

of a prior notice, which shall only be effective upon receipt.

        At any time or times when Tenant's interest herein shall be vested in
more than one person, firm or corporation, jointly, in common or in severalty, a
notice given by Landlord to any one such person, firm or corporation shall be
conclusively deemed to have been given to all such persons, firms, or
corporation. Any notice by Tenant pursuant to the provisions hereof shall be
void and ineffective unless signed by all such persons, firms or corporations
unless such persons, firms or corporations shall have previously given notice to
Landlord, signed by each of them designating and authorizing one or more of them
to give the notice referred to, and such notice shall then be unrevoked by any
notice to Landlord.

18.02 - Certificate by Tenant

        Within ten (10) days after request by Landlord from time to time, Tenant
shall deliver to Landlord or to a person, firm or corporation, specified by
Landlord, a duly executed and acknowledged instrument, certifying:

        there has been any modification, that the Lease is in full force and
        effect, as modified, and identifying the date of any such modification.

        (ii)   whether Tenant knows or does not know, as the case may be, of any
        default by Landlord of the terms, covenants, and conditions of this
        Lease, and specifying the nature of such defaults, if any;

        (iii)  whether or not there are any then existing set-offs or defenses
        by Tenant to the enforcement by Landlord of the terms, covenants, and

22.01 - Holdover

        Should Tenant continue to occupy the Premises after the expiration or
earlier termination of this Lease, whether with or against the consent of

22.02 - Limitation on Personal Liability

        It is understood and agreed that Tenant shall look solely to the estate
and property of Landlord, its successors and assigns, in the Building for the
satisfaction of Tenant's remedies for the collection of a judgment (or other
judicial process) requiring the payment of money by Landlord, in the event of
any default or breach by Landlord with respect to any of the terms, covenants
and conditions of this Lease to be observed or performed by Landlord and any
other obligations or liability of Landlord created by or under this Lease, and
no other property or assets of Landlord, its successors and assigns, or of their

procedures for the satisfaction of Tenant's remedies.

22.03 - Definition of Landlord

        The term "Landlord", as used in this Lease, shall be limited to mean and
include only the owner of the Building (or the owner of a lease of the
Building), at the time in question.  In the event of any transfer or transfers
of the Landlord's interest in this Lease or the title to the Building (or in the
event of any lease of the Building or assignment of such lease).  Landlord
herein named (and in case of any subsequent transfer or conveyance, the then
grantor), including each of its partners, beneficiaries, co-tenants,

any performance or the making of any improvements or repairs or fulfilling any

by fire, catastrophe, strikes or labor trouble, civil commotion, Acts of God or
the public enemy, governmental prohibitions or regulations or inability to

reasonable control, shall be added to such party's time for performance, and
such party shall have no liability by reason thereof.

22.05 - Relocation of Tenant

        Landlord reserves the right, and Tenant consents, to relocate Tenant to
other space with approximately the same square footage area within the Building

<PAGE>

22.06 - Failure to Give Possession

        If Landlord is unable to give possession of the Premises on the Term
Commencement Date by reason of the holding over or retention of possession of
any tenant, tenants, or occupants or for any other reason, or if repairs,
improvements or decoration of the Premises or of the Building are not completed,
such inability by Landlord shall not constitute a default under this Lease but
the Term Commencement Date shall be postponed until such date as such holdover
tenant or occupant shall give up possession of the Premises and the term of this
Lease shall be deemed to commence on such Term Commencement Date as postponed
(and the termination date of the term of the Lease shall be extended by the same
period as the Term Commencement Date is postponed)

the exercise of the power of sale under, any mortgage made by Landlord covering
the Premises, or in the event Landlord sells, conveys or otherwise transfers its
interest in the Building or any portion thereof containing the Premises. Tenant
shall attorn to and hereby covenants and agrees to execute an instrument in
writing reasonably satisfactory to the new owner whereby Tenant attorns to such
successor in interest and recognizes such successor as the Landlord under this
Lease.

22.09 - Definition of Tenant's Allocable Share

        For purpose of determining Tenant's Allocable Share herein, such share
shall be the percentage resulting from dividing the number of square feet set
forth in Section 1.01 above, by the total number of square feet in the Building,
which are leased as of the beginning of each lease year or partial lease year,
less the area occupied by the Ida Benderson Center.

22.10 - Division of Costs

of New York and shall be binding upon the parties hereto and their respective
legal representatives, successors and assigns except as expressly provided
otherwise. Use of the neuter gender shall be deemed to include the masculine or
feminine, as the sense requires. Any reference to successors and assigns of

to a particular assignment as required by the provisions of Article 15 thereof.

22.14 - Invalidity of Particular Provisions

        If any term or provisions of this Lease or the application thereof to
any person or circumstances shall, to any extent, be invalid or unenforceable,

unenforceable, shall not be affected thereby and each term and provision of this
Lease shall be valid and be enforced to the fullest extent permitted by law.

negotiation does not constitute an offer to lease, or a reservation of, or
option for, the Premises, and this document shall

                                      -22-
<PAGE>

be effective and binding only upon the execution and delivery thereof by both
Landlord and Tenant.

22.16 - Assignment of Rents or Sale and Lease Back

        (a) With reference to any assignment by Landlord of Landlord's interest
in this Lease, or the rents payable hereunder, conditional in nature or
otherwise, which assignment is made to the holder of a mortgage or ground lease
on property which includes the Premises, Tenant agrees:

            (i)  that the execution thereof by Landlord, and the acceptance
            thereof by the holder of such mortgage, or the ground lessor shall
            never be treated as an assumption by such holder or ground lessor of
            any of the obligations of Landlord hereunder, unless such holder, or
            ground lessor, shall, by notice sent to Tenant, specifically
            otherwise elect; and

            (ii) that except as aforesaid, such holder or ground lessor shall be
            treated as having assumed Landlord's obligations hereunder upon
            foreclosure of such holder's mortgage and the taking of possession
            of the Premises, or, in the case of a ground lessor, the assumption
            of Landlord's position hereunder by such ground lessor.

        (b) Where a party acquires the lessor's interest in property (whether
land only, or land and buildings) which includes the Premises, and
simultaneously leases the same back, such acquisition shall not be treated as an
assumption of Landlord's position hereunder, and this Lease shall thereafter be
subject and subordinate at all times to such lease.

performed by Landlord for the Building.  Tenant shall not use the Premises for
any illegal or immoral purpose.

The listing of any name other than that of Tenant, whether at the doors of the

at will by written notice to Tenant.

     (d) Tenant shall not advertise the business, profession or activities of
Tenant conducted in the Building in any manner which violates the letter or

ordinance or regulation or any condition imposed by standard fire insurance
policy issued for office buildings in the municipality where the Building is
located, or do or permit anything to be done, or keep or permit anything to be
kept, in the Premises, which would increase the fire or other casualty insurance

companies of good standing refusing to insure the Building or any such property
in amounts reasonably satisfactory to Landlord.

     (i) Tenant shall cooperate fully with Landlord to assure the effective

access thereto by all persons whose presence, in the judgment of Landlord, shall
be prejudicial to the safety, character, reputation and interests of the
